his report is the outcome of a country study conducted under the ALGAS project by Viet Nam. ALGAS, which stands for “Asia Least-cost T Greenhouse Gas Abatement Strategy,” is a study by 12 Asian countries
of national emissions of greenhouse gases (GHGs) in 1990, the projections of GHGs emissions to 2020, and an analysis of GHGs abatement options in different economic sectors. The study includes the formulation of national GHGs abatement strategies consistent with national development priorities, and the preparation of a portfolio of GHGs abatement projects and national action plans embodying national development objectives.
during 1995-1998 with funding of about $9.5 million from the Global Environment Facility (GEF) through the United Nations Development Programme (UNDP). The ADB also provided supplemental funding of $592,000. The Government of Norway and the Governments of participating countries likewise provided financial and in-kind contributions, respectively, to the project. With a budget of more than $10 million, this is the largest regional technical assistance project executed by the ADB. Apart from Viet Nam, the countries involved in the study are Bangladesh, People’s Republic of China, India, Indonesia, Republic of Korea, Mongolia, Myanmar, Pakistan, Philippines, Thailand, and the Democratic People’s Republic of Korea (DPRK). For DPRK, the country study is being executed by the United Nations Economic and Social Commission for Asia and the Pacific (UN ESCAP). Together, these countries contain more than one-half of the world’s population. The ALGAS project was designed to assist the countries to meet their commitments under the United Nations Framework Convention on Climate Change.
A team of national technical experts (NTEs) undertook each country study, with the active involvement of Governments through a designated national counterpart agency (NCA). The NTEs were drawn from different institutions of each country, and were assisted in their tasks by a team of international technical experts (ITEs). The ALGAS project involved a number of regional capacity-building activities, including training workshops on GHGs inventory preparation, analysis of GHGs mitigation options, empirical measurements of methane from rice paddies, analytical modeling of the energy and forestry sectors, and the preparation of project pre-feasibility reports. It also included study tours, supply of equipment, and a regional database. A regional thematic support group of experts who have contributed to the study was organized to help continue cooperation among the participating countries. The Environment Division, Office of Environment and Social Development of the ADB, with the active support of UNDP-GEF coordinated the study. The UNDP country offices provided significant logistics support and encouragement to the NTEs teams.
In the case of Viet Nam, the NCA was the Institute of Meteorology and Hydrology (IMH) of the Hydrometeorological Service. The NTEs team, which was led by experts of IMH, included experts of the Institutes of Agricultural Planning and Projection; and Forest Science; Electricity of Viet Nam; Ministries of Industry; Training and Education; Transportation; Science, Technology and Environment; and Agriculture and Rural Development; and Planning and Investment. At different stages of the study, the NTEs team conducted several national workshops in which interim results were presented and feedback obtained from government agencies, industry, researchers, and NGOs.

The ITEs team included experts of Alternative Energy Development Inc. (US) in association with Asian Institute of Technology (Thailand); Australian Bureau of Agricultural and Resource Economics; Hagler Bailly Services (US); ICF Kaiser (US); and Lawrence Berkeley National Laboratory (US). A number of institutions in the participating countries helped conduct various capacity- building activities. The ITEs team included several members from the region who were concurrently members of their respective NTEs teams. A group of independent international reviewers carried out peer reviews of each country study.
The completion of this report, together with its companion volumes on the other 11 participating countries and the Regional Summary report, is an indication of the success of this regional collaborative effort. Each country report comprises, besides an executive summary, chapters on country background; an assessment of energy, forestry and land-use change, and agriculture sectors; formulation of a national least-cost GHGs abatement strategy; a portfolio of least-cost GHGs abatement projects, a national GHGs action plan; and recommendations and future actions. It is hoped that the ALGAS reports would be useful to policymakers, multilateral and bilateral development agencies, the private sector, and researchers in the field both from within and outside the region, particularly those involved with climate change issues.

he Asian Development Bank (ADB) and the United Nations Development Programme (UNDP) are pleased to have had the T opportunity to join in working on the Asia Least-cost Greenhouse
Gas Abatement (ALGAS) Project. This is one example of our successful collaboration. We are particularly gratified to note the hard work put in by the country project teams and the international consultants to achieve a successful outcome of this Project. The commitments shown by the participating parties is a positive sign that efforts will be carried forward into follow-up work. We believe that this Country Report, the ten accompanying Country Reports, and the Summary Report, which have been released on the occasion of the Fourth Meeting of the Conference of the Parties to the United Nations Framework Convention on Climate Change in November 1998 in Buenos Aires, will be useful to the policymakers, donor agencies, researchers, and the broader Climate Change community. We hope that they will lead to further concrete steps by all of these parties to ensure that the work undertaken to date will bear fruit in significant action to mitigate climate change.

SECTION 1 EXECUTIVE SUMMARY
iet Nam is located in Southeast Asia, sharing land borders with People’s Republic of China, Laos, and Cambodia. It has a land V area of 330,990 km2, and stretches 1,650 km from north to south,
600 km at its widest and 50 km at its narrowest. It consists of more than 1 million km2 of water surface, with 3,260 km of coastline, and thousands of small islands, especially in the Tonkin Gulf. Viet Nam is the 12th most populous country in the world, with an estimated population of 72.5 million in 1994 and a population growth rate of 2.5 percent. About 20 percent of the population live in the urban areas, while 80 percent live in rural areas.
Viet Nam can be divided into three geographical regions: the South, the Central, and the North. The Mekong Delta in the south and the Red River Delta in the north are separated by a thin central strip. This clear distinction in geographical regions is also reflected in economic development. There are about 2,860 rivers in Viet Nam. The Red River and the Mekong River are the largest and most important ones. Viet Nam is located in the inter-tropical zone, but because of its long north-south span, climate conditions vary from sub- zero temperatures in the northern mountains to the year-round heat of the Mekong Delta.
Viet Nam ratified the United Nations Framework Convention on Climate Change (UNFCCC) on 16 November 1994. The Hydrometeorological Service (HMS) has been assigned by the Government to take full responsibility for climate change issues and for implementing programs related to the objectives of the UNFCCC.
A Viet Nam Climate Change Country Team (VNCCCT) was established in 1994 with a mandate to improve knowledge on climate change and its social, economic and environmental impacts. The Director General of HMS chairs the VNCCCT. It is represented by all relevant ministries and government agencies including representatives from Ministry of Planning and Investment, Ministry of Science, Technology and Environment, Ministry of Industry, Ministry of Transportation, Ministry of Agriculture and Rural Development, Ministry of Training and Education, Ministry of Foreign Affairs, Viet Nam Union of Scientific and Technical Associations, and Hydrometeorological Service. The VNCCCT has remained as the main policy advisory body in the area of climate change. It played a key role in the implementation of the ALGAS Project, and it is charged with overseeing and advising on the implementation of the Project.
Other studies in Viet Nam related to climate change are described below.
Regional Studies on Global Environment Issues: The study was sponsored by ADB for eight Asian countries, including Viet Nam. It studied the socioeconomic impacts of climate change and policy options to cope with climate change. Vulnerability Assessment in Viet Nam, funded by the Netherlands. Started in 1994, its objective was to undertake the vulnerability and impacts assessment on the coastal zone. Socioeconomic and Physical Approaches to Analyzing Climate Change Impacts in Viet Nam. Funded by the United Kingdom, this research project started in 1996. It is a study of socioeconomic vulnerability to climate change impacts in the coastal zone of the Red River Delta of Viet Nam.

EXECUTIVE SUMMARY
Mitigation Assessment: This study deals with GHGs mitigation analysis and cost-effective options. UNDP/UNITAR/GEF CC: TRAIN (Phase 1): Its objective was to assist the countries in formulating climate change policy for the implemen- tation of the UNFCCC.
The total net emissions of greenhouse gases (GHGs) in Viet Nam, using 1993 as the base year, were: 64,062 Gg CO2, 2,588 Gg CH4, 14.63 Gg N2O, 182.09 Gg NOx and 3,127.56 Gg CO. Using a global warming potential (GWP) of 1 for CO2, 21 for CH4, and 310 for N2O, the contribution of these three gases in terms of CO2-equivalent or GWP is equivalent to a total CO2 emissions of 111.7 million tonnes (mt), which is contributed by:
Carbon dioxide, 64 mt,
The three sectors that emitted the largest quantities of GHGs are
Methane, 54.4 mt of CO2-equivalent, and Nitrous oxide, 4.5 mt of CO2-equivalent.
agriculture, forestry, and energy. The agriculture sector contributed 48 mt of CO2-equivalent while the forestry sector emitted 31 mt CO2-equivalent, and the energy sector emitted 27.5 mt of CO2-equivalent (Table 1-1). Total GHGs emissions in CO2 equivalent by sector in 1993 are presented in Figure 1-1.

GHGs emissions from the energy sector in 2020, based on projection of the energy demand and the primary energy supply, were projected to be morethan 8 times as high as in 1993. The total GHG emissions from the energysector are projected to increase from 22.31 mt in1993 to 196.98 mt at the endof the study period. (Table 1-2 and Figure 1-2) This corresponds to an averagegrowth rate of 6.7 percent per year.

In the forestry sector, the highest CO2-equivalent emissions were produced in 1993, but forestry sector emissions have been decreasing since then, and shortly after 2000 the sector is projected to become a net sink for CO2 (see Figure 1.2).
The agriculture sector’s emissions are gradually increasing, with the annual growth rate of 0.1 to 0.2 percent.
The growth rate of GHGs emissions from the energy sector is faster than those of the agriculture and forestry sectors. The total GHGs emissions from the three sectors shows a steeply increasing trend starting in year 2000.The net annual growth rate from 2000 to 2020 is 6.5 percent.
A list of GHGs mitigation options was developed for each sector, and based on the list, a wide range of policy and technology options were identified that could be considered to reduce GHGs emissions or enhance sinks.
Potential mitigation options that could provide GHGs abatement in the energy sector are as follows.
Demand-side energy efficiency measures:
(i) Improve energy efficiency in fuel combustion processes used in industry.
(ii) Highly efficient cooking stoves in rural areas. (iii) Energy-efficient industrial boilers to replace low-efficiency models. (iv) Switching from coal to natural gas for cooking in urban areas. (v) Energy efficient compact lamp for lighting. (vi) Highly efficient electric motors to replace standard electric motors. (vii) Highly efficient household electric equipment. (viii) Increased vehicle fuel efficiency. (ix) Waste heat recovery power generation.
Supply-side measures:
(x)
(xi)
Fuel switching to renewable and less-carbon-intensive energy sources. Improvement in efficiency of fossil fueled power plants.

SECTION I
The forest mitigation options aim at carrying out reforestation and forest protection at a national level. In addition, scattered tree planting activities by local households provide a number of economic benefits as well as reducing deforestation.
GHGs mitigation options in the forestry sector are as follows:
(i) Reforestation of degraded forest areas under long and short rotation period.
(ii) Natural regeneration. (iii) Forest protection. (iv) Scattered tree planting.
Viet Nam is an agricultural country, with 75 to 80 percent of its population living in the countryside engaged in the agricultural production of over 7.3 million hectares (mha) of agricultural land.
The most significant agricultural sources of methane emissions are rice cultivation and livestock. Agriculture sector mitigation options should meet the following general guidelines:
Increase agricultural production levels.
Potential GHGs abatement options for the agriculture sector is:
(i) Water management in irrigated rice paddy fields. (ii) Change in cropping patterns from the two rice crop to three crop
system (rice - upland crop - rice). (iii) Sowing directly to rice paddy fields. (iv) Using bio-fertilizers (composite) on the field crop. (v) Rational feeding of livestock. (vi) Using biogas in rural areas.
The macroeconomic scenario for all sectors is based on the gross domestic product (GDP) growth rate and GDP structure that was projected by the Development Strategic Institute (Table 1-3). Projected baseline GHGs emissions for each sector is given in Table 1-2. It should be noted that these projections were made prior to the recent turndown of the Asian economies in the region.
Not require significant amounts of hard currency. Result in products that will be accepted by local consumers.
The Energy Flow Optimization Module - Environment (EFOM-ENV) was used to develop and analyze baseline and mitigation scenarios. Descriptions of the technology-specific scenarios in the energy sector are given in Table 1-4.
costs compared with the business-as-usual (BAU) scenario (Table 1-5). The results show that all energy demand-side abatement options are “win-win” (negative cost) options. On the supply side, wind power construction is a cost- effective option. However, fuel switching for coal and oil thermal-fired power plants is more expensive than the baseline.
The individual mitigation options were evaluated for GHGs emissions and

Two approaches to placing constraints on GHGs emissions were evaluated using the EFOM-ENV model. The ABAT01, ABAT02, and ABAT03 cases set constraints on, CO2 emissions in year 2020 to be reduced by 5 percent, 10 percent, and 15 percent, respectively, compared to the BASE case, which is the least cost solution. The discounted cost of the ABAT01 case is higher than that of the BASE case but lower than BAU case (Table 1-6).

Based on the Master Plan of Ministry of Agriculture and Rural Development (MARD), GHGs emissions and carbon sequestration in the forestry sector has been projected to the years 2000, 2010 and 2020.
In past years, the rate of reforestation has increased from year to year. Every year, more than 100,000 hectares (ha) of forest are planted. However, the natural forests are shrinking in area due to shifting cultivation and clearing for permanent agriculture. They are also being degraded through unsuitable exploitation for logs and fuelwood. Deforestation continues as a serious problem of the country. It is estimated that the rate of annual forest loss is about 150,000 ha. This problem needs to be solved in the coming years.
For the ALGAS Study, three scenarios were developed: Baseline, Technical Potential, and Feasible scenarios. All forestry options under the three scenarios were developed and analyzed with the Comprehensive Mitigation Analysis Process (COMAP) model. The Baseline scenario is considered a likely-trends scenario. The Technical Potential scenario is based on the Government’s policy relating to reforestation, afforestation, and natural forest protection. The Feasible scenario assumes that levels of implementation of forestry options are higher than in the Baseline scenario but lower than in the Technical Potential scenario. This scenario is considered to be more feasible than the Technical Potential scenario because of existing socioeconomic and technological conditions in the country. Five forestry mitigation options are suggested for this scenario, in which the rate of reforestation would be about 140,000 ha per year, while 4 billion scattered trees would be planted during the period 1994-2020. In addition. 6.5 mha of existing natural forests would be protected, and 1.9 mha of degraded forest areas would be managed under enhanced natural regeneration in the whole period.
Feasible scenario. Forest protection has by far the largest abatement potential. Table 1-8 describes the Baseline Scenario and the forestry options under the
The Baseline scenario for the agriculture sector assumes that the rice cultivation area grows from 6.5 mha in 1993 to 7.3 mha in 2010 and 7.7 mha in 2020. The population of animals increases from 6.2 million head of

The abatement options in this sector are:
Water management with intermittent draining of rice fields during the growing season. Water management can reduce methane emissions by 20–50 percent, while at the same time increasing yield by 6–8 percent. Improving the nutrition of livestock through mechanical and chemical feed processing.
GHGs emissions and investment costs of reducing methane emissions from agriculture sector activities are given in Table 1-9. The methane emissions avoided under mitigation options A1 and A2 are 93x103 tonne in 2000, 194x103 tonne in 2010, and 295x103 tonne in 2020.

Cost of Emissions Reduction Initiative (CERI) curves relate the quantity of GHGs that can be reduced or sequestered by mitigation options and the cost of mitigation per unit of GHGs reduction.
CERI curves for GHGs mitigation in the energy sector were developed from EFOM-ENV model results.
The CERI curve for the individual mitigation options (Figure 1-3) shows that most of the overall mitigation potential has a negative abatement cost; that is, the mitigation technologies result in lower overall system cost than do the BAU technologies. The option with positive cost is fuel switching in existing power stations.
Figure 1–4 illustrates how the incremental cost increases as more stringent constraints on GHGs emissions in year 2020 are placed on the energy system. In this figure, each step in the curve relates to a specific case (see Table 1-6). The initial step, which has significant negative cost, refers to the BASE case. In this figure, the emissions abatement is the quantity in year 2020 only.

Based on the COMAP modeling results, CERI curves were developed for three scenarios. Figures 1-6, 1-7, and 1-8 express the relationship between the potential carbon reduction (or carbon stored) and cost per unit abated by the identified forestry mitigation options under the different scenarios. The types of option are the same in the Baseline and Feasible Scenarios, but the assumed rate of activity (and the cumulative abatement) is greater in the latter scenario. Forest protection is both the least-cost option and the one with the largest abatement potential. Short rotation reforestation is the most expensive option.

The overall national policy in the energy sector is to satisfy the energy demand for long-term development of the country with a high GDP growth rate, and provide national, regional, and global environmental benefit. The specific objectives of the Action Plan based on the National Energy Development Program (NEDP) focuses on development of clean energy sources, with special attention given to:
Hydroelectricity,
Nuclear electricity.
The National GHGs Abatement Action Plan will be developed in the National Energy Environment Plan (NEEP) through sectoral regional and national strategies and socioeconomic development plans. The main environmental implications considered in the NEEP are the emissions of CO2, SO2, NOx and dust. For environmental management, a system of regulation based on cost-benefit with environment assessment analysis will be

developed. The appropriate environmental policies will be undertaken in the energy sector based on a least-cost plan, recognizing the environmental impacts. The following issues are considered in development of the national policies:
Energy efficiency Renewable energy exploitation Environmental standards and environment cost benefit analysis for
energy projects.
The Action Plan calls for implementing the identified abatement options and projects through short, medium, and long term measures.
For implementation of the Action Plan, the National Climate Change Office should work in close linkage with all sectoral environmental offices, energy management offices, and energy monitoring offices, such as the DSM Cell and Energy Efficiency Office. The Climate Change Office will coordinate activities taken under the action plan and specific projects will be implemented by sectoral agencies.
The main document on the economic and social development of Viet Nam specifically indicates that the forestry sector should concentrate on (i) improving the economic results of the operations, (ii) increasing the rate of forest plantation, (iii) accelerating revegetation of bare hills, (iv) improving the results of forest exploitation, and (v) creating a forest resource capable of protecting the environment and harboring diverse wildlife. In the next decade, several concrete objectives for the forestry sector include:
Strengthen the national protection capability by means of protecting 9.3 mha of existing forests, increasing the rate of forest plantation, and accelerating revegetation of bare hills. Focus on activities concerning natural forest regeneration, establish- ment of new plantations in order to reforest 5 mha in the period 1998- 2010. Up to the year 2010, there will be more than 15 mha of forests all over the country. To increase forest coverage to 45 percent by the year 2010. Provide employment for local people and improve the living standard for more than 20 million people living in and around forest areas.
For the forestry sector, the GHGs abatement action plan is focused on several activities:
Forest plantation establishment Forest protection/conservation Planting scattered trees Information and education.
In order to implement the forestry options successfully, it is necessary to encourage all other economic sectors as well as local communities to take part in forest operations. A forest management system should be established from central to local levels (MARD Provinces Districts Communes), and links

in the forestry sector is as follows. The proposed time-line for implementing the GHGs abatement strategy
Short term (1998 - 2005):
Reforestation at a rate of 140,000 ha of degraded forest land per year. Planting 1.5 billion scattered trees. Protecting 6.5 mha of natural forests. Rehabilitating 1.8 mha of degraded forests.
Medium term (2005 - 2015):
Reforestation at a rate of 100,000 ha of degraded forest land per year. Planting 2 billion scattered trees. Continue rehabilitating 1.8 mha of degraded forests. Continue protecting the natural forest, expanding protected land area, and maintaining forest plantations.
Long term (beyond 2015):
Revegetating 0.8 mha of wasteland. Planting 0.5 billion scattered trees. Harvesting a number of forest products from forest plantations that were established in the short-term period (1998 - 2005) to meet the in-country demand as well as wood export. Determining the GHGs mitigation options that should be continued and new options and strategies that need to be formulated.
The strategy for the agriculture sector is to satisfy the food requirements for the people’s consumption in any situation, to assure the food source through development of breeding and provision of enough raw materials for the industry, and to effectively increase the export volume. These goals are supported by the following programs:
Diversification of agriculture.
The mitigation measure for methane emissions from rice fields is controlling water irrigation and the intermittent draining of rice fields during the end of tilling and after flowering. It is expected that implementation of this practice will result in significant reduction of methane emissions from the agriculture sector in coming years.
Methane emissions from the livestock subsector will be mitigated by improving nutrition and through mechanical and chemical feed processing.
Intensification of cultivation and increasing productivity of the food crops.
VIET NAM
SECTION 1
There are five projects proposed in the Viet Nam ALGAS Project. A summary of the priority projects is presented in Table 1-11.
(i) The National Action Plan for implementing UNFCCC will integrate all sectoral plans addressed to GHGs abatement and climate change adaptation strategies. This plan will be submitted to the Government for approval.
(ii) The Government should establish an organization that will have a legally well defined mandate, logistically well supported operation, and technically skilled personnel to implement the National Action Plan. The tasks and functions of the organization will include GHGs inventory, database management, and monitoring and evaluation of GHGs emissions, programs, policy, projects and activities related to GHGs reduction.
The Viet Nam Climate Change Country Team (VNCCCT) was estab- lished in 1994, with a mandate to improve knowledge on climate change and its social, economic, and environment impacts. The VNCCCT is represented by all the relevant ministries and government agencies relating to climate change issues. It will play a key role in the implementation of the National Action Plan.
iii) In the energy sector, the National Energy Plan should integrate energy efficiency for both the supply and demand sides. In the forestry sector, the programs such as forest protection, watershed manage- ment, biodiversity conservation, reforestation, and settlement of shifting cultivation will be performed to implement the GHGs abatement strategies. In the agriculture sector, reducing methane emissions from rice paddy should be included in the program of making more intensive cultivation of the food crops.
iv) The establishment of demonstration projects can help to show the barriers and constraints of implementation and also show the best way to carry out programs and projects.
v) There is a need to build and strengthen the national capacity to integrate climate change concerns into medium- and long-term planning. This should include education and training on climate change for national development planners, as well as for policy decision- makers from all relevant ministries and government agencies.
At the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil, June 1992, Viet Nam signed the United Nations Framework Convention on Climate Change (UNFCCC). Viet Nam Government ratified the Convention on 16th November 1994.

SECTION 2 INTRODUCTION AND
BACKGROUND
he territory of Viet Nam includes the land area of 330,990 km2 and immense sea space with thousands of islands. Its territorial waters are T 12 miles wide, and the sea exclusive economic zone is 200 miles wide
covering an area about 1 million km2. The territory ranges from 23o23' to 08o02' North latitude and from 102o08'
to 109o28' East longitude. Viet Nam is 1,650 km long from North to South. From West to East the widest part is 600 km and the narrowest part is 50 km only. The entire length of the coastline is 3,260 km.
Viet Nam has a great number of mountains; many of them have a height of more than 2,500 meters. The mountainous area occupies three-fourths of land territory. There are more than 2,860 large and small rivers; among these rivers more than 2,300 have a length of more than 10 km. On average, there is an outlet approximately every 20 km along the coastline. The Red River of North Viet Nam and the Mekong River of South Viet Nam are the largest and most important ones.
Viet Nam possesses a monsoon tropical climate, characterized by a tropical solar radiation regime with plentiful total solar radiation and positive values of monthly solar radiation balance. It also has a monsoon wind regime marked by a noticeable change of prevailing winds from summer to winter. Annual mean temperature ranges from 8°C - 29°C, varying with latitude and altitude. The monthly mean temperature of the coldest month (December or January) is about 13°C - 20°C in the northern parts, and mountains in South Viet Nam at a height of more than 1,000 meters. The coldest month mean temperature is about 20°C - 25°C in the plains and in the mountains with the height less than 1,000 meters in the southern parts. The temperature in the hottest month (between March and July) is about 25°C - 30°C in the plains throughout the territory and decreases with altitude. Throughout the territory, including highlands, midlands, and plains, annual mean rainfall ranges from 600 - 5,000 mm with 100 - 200 days of rain annually. The rainy season is from April/May to September/October in most parts of the territory, and from August/September to December/January in several coastal regions of central Viet Nam. The annual mean number of typhoons is four to five for the period of 1901-1960 and six to seven in the past three decades.

INTRODUCTION AND BACKGROUND
Viet Nam had a population of 71 million in 1993. The estimated population in 1995 was 74 million. It has a high rate of population growth. On average, the population growth rate is 2.23 percent per year. During the last 10 years the growth rate has been decreasing. In 1993, urban population constituted approximately 20 percent of the total population. According to the survey carried out in July 1994, the total number of rural households is 12 million. The labor force is 45.8 percent of the population. In cities, the majority of the labor force work in industrial and commercial activities or other services. In villages, most of the population take part in agricultural production. In coastal zones and islands, most of the population work in fishery.
The monthly average income over the whole country is D119,000, and urban and rural average monthly income are D220,000 and D94,000, respectively. About 65.8 percent of the population has less than the average income, and poor households consist of 40.9 percent of the total.
Viet Nam has a young population with a high labor proportion and literacy rate. At present the population aged under 20 years comprises about 49 percent, and the population of working age comprises more than 50 percent of the total. According to the 1989 census, 87.7 percent of the population aged 10 years and over were literate.
Viet Nam still remains a backward agricultural-based economy. In 1993, products from the industry, agriculture, and service sectors constituted 28.9, 29.9, and 41.2 percent of the gross domestic product (GDP), respectively.
In agriculture, the gross output of cultivation and animal husbandry contribute 74 and 26 percent, respectively, of the total output. Industry is structured by electricity, fuels, ferrous and non-ferrous metallurgy, equipment and machinery, electrical products, chemical products, fertilizers, construction materials, cellulose and paper, wood and wood products, foodstuffs, textile products, sewing products, tanning and manufactured leather products, printings, etc.
Industrial production reached a growth rate of 10.0 percent in 1991, 17.1 percent in 1992, 12.7 percent in 1993, 13.7 percent in 1994, and 14 percent in 1995. Growth rates differed from sector to sector: crude oil, 23.3 percent; power, 20.8 percent; cement, 18.3 percent; rolling steel, 30.3 percent; tool machinery, 14.8 percent; chemical fertilizer, 20.4 percent.
In 1993, the GDP was D136,571 billion, or approximately $14 billion, equivalent to approximately $200 per capita.
In the five years 1991-1995, the economy of Viet Nam was characterized by a relatively high economic growth rate in most sectors: 12.5 percent in industry, 9.1 percent in services, and 4.3 percent in agriculture. The average GDP growth rate in the period reached 8.2 percent. It was 8.8 percent in 1994 and 9.5 percent in 1995.

During 1996-2000 Viet Nam’s economy should achieve an average annual growth rate of 8.5 percent. Agriculture (including forestry and fishery) should experience an annual increase of 4.2 percent, industry (including construction) 12.5 percent, and the service sector 7.6 percent. With such a growth pattern, GDP at 1994 prices will reach $26 billion by the year 2000.
Up to the year 2000, the area of rice field is projected to increase to 7.0 mha, and food output is projected to continue its rapid increase. The food output is expected to be not less than 20 mt of rice equivalent. By the year 2000, the area of forest cover is projected to increase to 11 mha and forest coverage is projected to be more than 30 percent.
is projected to reach $108 billion. The share of industry, services, and agriculture of the total GDP is projected to be 44.0 percent, 43.9 percent, and 12.1 percent, respectively. The GDP per capita is expected to reach $1,025 per person. In order to gain this objective, the growth rate of the total GDP should be 7.8 percent in the period 2001 to 2010 and 7 percent in the period 2011 to 2020.
According to the Government’s plan, by the year 2020 the area of rice fields is projected to be 7.7 mha and rice production is projected to reach 44 mt per year. Livestock population is projected at 7 million cattle, 4.5 million buffaloes, and 38 million swine.

iet Nam has recently succeeded in maintaining high growth with good macroeconomic performance. This development has required V increased demand for energy; as society develops, the economy
expands, and the demand for energy becomes greater.
with Viet Nam’s GDP growth of 8.8 percent per year from 1992 to 1995 (Table 3-1), primary energy consumption in the country grew significantly from 7,530 ktoe in 1992 to 11,270 ktoe in 1995, an average annual growth rate of 14.4 percent.

Favorable conditions for economic development mean Viet Nam’s rapid economic development is likely to continue. According to the latest economic projection by the Ministry of Planning and Investment in 1998, the annual average GDP growth rates will be 8.5 percent, 7.8 percent, and 7 percent in the periods 1996-2000, 2001-2010, and 2011-2020, respectively (Table 3-2). This means that a large amount of energy will be consumed in the corresponding periods because energy is vital for the development of industry and commerce, which will sustain a high rate of economic growth.
GDP is the total production from three main economic sectors: industry and construction, agriculture, and service. Of these three, the industry and construction is the most energy intensive and has the highest growth rates: 12.5 percent in 1996-2000, 10 percent in 2001-2010 and 8 percent in 2011- 2020 (Table 3-2). The industrial sector plays a major and increasing share in economy (30 percent, 35.5 percent, 41.5 percent, and 44 percent in the years 1995, 2000, 2010 and 2020, respectively) (Table 3-3). Thus this sector is expected to use the largest amounts of energy. Energy demand is expected to continue increasing during the two coming decades, reaching 101,378.89 ktoe of primary energy by the year 2020. This increase in energy use will cause an increase in the growth of GHGs emissions.

Compared to most of other developing countries, Viet Nam is relatively rich in primary energy resources. Coal deposits, located in the north, are estimated to have recoverable reserves of 3,410.1 million tonnes (mt) of anthracite, 383 mt of lignite and 100 billion tonnes (bt) of bituminous (Report of Viet Nam Coal, 1998). Viet Nam’s overall hydro potential is estimated at 17,000 MW with about 70 percent in the North (Energy Institute, 1997). Crude oil reserves have been discovered in the southern offshore areas with recoverable reserves of 1 billion barrels (World Bank report, 1993), and production increased to 8.6 mt in 1996. The natural gas reserves of 3 trillion ft3 were identified in 1993 (World Bank report, 1993). Despite these energy resources, Viet Nam has one of the lowest levels of energy consumption in the developing world. However, energy consumption per capita has increased continuously from 63.6 kgoe in 1985 to 64.2 kgoe in 1990, reaching 91.2 kgoe in 1994 which reflects an improvement in the country’s standard of living.
characterized by its behavior in three periods: from 1980 to 1985 when there was a centralized economic system, energy consumption was more or less constant, petroleum product consumption, and electricity grew at about 8.9 percent per year. During this period, supplies of both petroleum and electricity were limited. From 1986 to 1990, after the beginning of economic reform, petroleum products and electricity consumption began increasing. The third period, from 1990 to 1994, was characterized by a rapid increase in all types of energy consumption. Total final energy consumption increased from 4,249 ktoe in 1990 to 6,613 ktoe in 1994 (Table 3-4), at an average annual rate of about 12 percent, a trend which is expected to continue and lead to an increase of the growth of GHGs emissions.

Total energy consumption rose rapidly from 4,529 ktoe in 1991 to 6,731 ktoe in 1994 with an annual average growth rate of 14 percent (Table 3-5). Liquid fuel was the dominant type of fuel consumed, with an average growth rate of 19 percent per year. Liquid fuel consumption reached 4,034 ktoe in 1993 and 4,591 ktoe in 1994; solid fossil fuel consumption doubled during the same year. The difference in consumption of these fuels was not so great during 1991-1992, a result of growing demand in the industrial, transportation, residential, and commercial sectors for liquid fuel for power generation. Natural gas has been used for power generation and contributed a small part too in fossil fuel consumption.
Energy is consumed in Viet Nam primarily by five major economic sectors: industrial, transportation, agricultural, residential, and commercial. Among these the industrial sector has been the largest consumer of fossil fuel. Its consumption was 2,408 ktoe in 1994 (Table 3-5), increasing from 1,859 ktoe in 1991, accounting for more than 30 percent of total fossil consumption. The combined residential and commercial sector followed with 1,944 ktoe in 1994, rising from 879 ktoe in 1991. The share of the residential and commercial sectors increased from 19 percent in 1991 to 28 percent in 1994. Fossil fuel consumption for power generation decreased lightly to 914 ktoe in 1994 from 936 ktoe in 1991 because of substitution of petroleum products from coal (these products have a higher efficiency in power generation). The sector with the lowest consumption is agriculture. Its share was only 4 percent between 1992 and 1994.

The first GHGs inventory for the energy sector in Viet Nam was compiled in 1992-1993, and it covered only the emissions from combustion activities in 1990. For that inventory, National Technical Experts (NTEs) employed the methodology proposed by the Organization for Economic Cooperation and Development (OECD).
The Energy Economics Division of Hanoi University of Technology conducted the sector GHGs Inventory for this report. It involved the cooperation of various institutions including Electricity of Viet Nam, the Institute of Meteorology and Hydrology (IMH), the Institute of Energy, the Institute of Transport Science and Technology, and the Ministry of Planning and Investment. GHGs emissions from the energy sector in 1993 were estimated from energy combustion and fugitive emissions. The results are presented in Standard Format of the Intergovernmental Panel on Climate Change (IPCC).

Fugitive emissions were estimated from coal production as well as production of crude oil and natural gas. Fugitive emissions from coal mining include methane CH4. Fugitive emissions from crude oil and natural gas are also in the form of CH4. The production processes that cause fugitive emissions are:
Energy transformation, i.e., power generation, Fuel combustion for the energy industry,
Combustion in the residential sector, and
Post-mining activities Crude oil production Natural gas production Flaring: emissions from burning of discarded and associated gas
during production
Coal mining: underground and surface mining activities
a. Methods
Under the IPCC guidelines for National GHGs Inventory, three steps were taken to estimate GHGs emissions from energy sources in Viet Nam.
Baseline data were collected for the sectors covered using a top- down approach, and secondary sources. Appropriate emissions coefficients were selected from among IPCC emissions coefficients for each type of energy in the study. IPCC procedures were applied to estimate GHGs emissions using the Global Average method for fugitive emissions and production- based average emission factors for fuel combustion.
b. Assumptions
The following assumptions were used in the calculation of GHGs emissions:
Emissions of almost all GHGs in the energy sector come from burning fossil and traditional biomass fuels. The calorific value given by IPCC was used for domestic anthracite.

Traditional biomass fuels consist of wood and rice residues. The consumption of these fuels is estimated based on per-capita con- sumption data provided for rural and urban areas by the Energy Institute. CO2 emissions were estimated based on the basic IPCC assumption and carbon contents of each fuel consumed by various economic sectors. The emission factor for road transportation is adopted from the results of an Indian study. This choice was based on the technological similarity between road transportation vehicles in India and Viet Nam.
The data for energy production, storage, and consumption in Viet Nam come from secondary sources, listed by fuel types and by economic sectors. These data were obtained from the results of the report of national project KC.03.01, 1995.
Biomass consumption data were estimated based on an average per-capita consumption per capita rural and urban areas provided by the Energy Institute.
Most coefficients used are those given by the IPCC. The emissions factors for CO2 in the transportation sector and for CH4 were based on the results of an Indian study.
The results of the estimation of GHGs emissions from energy sector sources in Viet Nam in 1993 are presented in Table 3-6. It is estimated that coal production emitted 78 Mg of methane and 7,352 Gg of CO2. Total emissions from fossil fuel reached 22,939 Gg CO2-equivalent in 1993. The industry sector had the highest GHGs emissions (6,932 Gg CO2-equivalent in 1993, followed by power generation (Table 3-6).

1. End-use:
The industrial sector emitted 7 mt of CO2-equivalent or 40 percent of the total energy sector emissions.
The commercial and service sector emitted 4 mt of CO2-equivalent or 18 percent of the total emission from the energy sector. Emission contained 3.8 mt of CO2, small amounts of nitrous oxide, and negligible amounts of methane.
The transport sector emitted 2.7 mt of CO2-equivalent or 11 percent of total emissions from energy sector. Carbon monoxide (CO) emissions were about 200 mt with a small amount of NOx, and a negligible amount of CH4.
The other sectors, including agriculture, emitted 3 mt of CO2-equivalent or 13 percent of the total emissions from energy sector. These emissions consist almost entirely of CO2; amounts of other gases were negligible.
2. Conversion:
The power sector emitted 6 mt of carbon dioxide equivalent or 25 percent of total emissions from the energy sector. Emissions were mainly CO2 (3.5 mt), with negligible amounts of CH4, N2O, and CO.
3. Fugitive:
Activities that generate fugitive emissions in Viet Nam include coal, oil, and gas exploitation and production. However, the data used for the estimation of fugitive emissions from oil - gas production in 1993 were not available, so fugitive emissions are estimated for coal mining only, including underground and surface mining activities. There are no local specific emission factors in Viet Nam, so fugitive methane emissions from coal mining is estimated based on CH4 emission coefficients used in India for different types of mining. Fugitive emissions from fossil fuel contained about 0.8 mt of CO2-equivalent or 3 percent of total emissions from the energy sector. Emissions of methane were about 0.076 mt.

Although experienced experts from various related institutions and ministries carried out the GHGs Inventory for the energy sector, there are still limitations.
Most of data used in this study came from secondary sources. One of the weaknesses of using these sources is the inability to verify their reliability. This study ignores emissions data that are not available at present, which also reduces the accuracy of the results. Almost all the coefficients used for the inventory were provided by IPCC. Local coefficients are not available, and there are large differences in end-use energy technologies and technical manage- ment and practices. Detailed data at the subsectoral level are not available; breakdown of consumption by subsectors has been approximated.
Following the results of the 1993 inventory, GHGs emissions from the energy sector were estimated at 27 mt CO2-equivalent, not including the CO2 emissions from traditional biomass burned for energy. The consumption of energy in the industrial sector ac- counted for the largest quantities of GHGs gases. Experts from various ministries and institutions carried out the inventory, with experience in energy activities and a good under- standing of the IPCC approach. More national technical experts have to be educated in order to be able to crosscheck results. Data used for preparing the inventory are from official govern- ment sources. Some corrections were made in the new version of the energy sector GHGs inventory in 1993 based on the updated data submitted by the ministries. Regarding future projections of energy demand, Viet Nam, like many other developing countries, needs to develop its economy; this economic growth will lead to the use of more energy and thus to production of more GHGs emissions. The total projections of energy sector GHGs emissions are estimated at about 340 mt CO2- equivalent to the year 2020. The main limitation of this inventory comes from the use of coefficients. Almost all the coefficients used for preparing the inventory were provided by IPCC. Local coefficients are not available, and there are large differences in end-use energy technologies, and technical management and practices among different areas in Viet Nam. The inventory was carried out for the year 1993 because of the availability of data for that year. For submission to UNFCC, the results should be updated with 1994 data. More time may be needed to verify each crucial figure on site, including emissions in the transport sector. As a result of the experience gained from the implementation of the inventory under the ALGAS Project, Viet Nam plans to conduct a national GHGs inventory first for its initial national communication and thereafter, on an annual basis. The climate change office will be

strengthened to its full capacity to establish a network for real-time data collection. This office will be responsible for preparing the annual GHGs inventory.
The energy sector in Viet Nam as described above is one of the most important components of the macroeconomic and social development of the country. It has the main priority in the Country Development Plan. The growth rate of energy demand, since 1992, has been on average 14.4 percent, higher than the growth rate of the economic output, and the energy demand in the future will continue to grow at a high rate. It is obvious, that GHGs emissions will increase significantly in the future. At present, the value of GHGs emissions from the energy sector is 22.2 mt CO2-equivalent. It represents 31.5 percent of all national GHGs emissions. Projected GHGs emissions in year 2010 will be 5 times higher and in 2020, 7 to 8 times higher than that in 1993. Thus, measures to mitigate GHGs emissions need to be implemented in the energy sector.
At present, energy production and end-use energy technologies used in Viet Nam are old technologies resulting in a high consumption of energy per unit of output in Viet Nam compared with the OECD countries. Energy consumption compared to European Union (EU) industries are as much as 50 percent higher for thermal uses and 30 percent for electricity uses.
Specific technological efficiency data provided by sectoral studies and surveys are given in Table 3-8. These data show the technological development level of both the energy supply and the end-use energy sectors.

Because of limited sources of data, the mitigation option assessment of the energy sector is limited. Sufficient data on technological costs are not available at present. It has been decided to use the 1995 investment costs of modern technology. These costs may change over time, but in the present assessment the costs are fixed at the 1995 level. The discount rate has been assumed to be 10 percent.
The energy supply and the energy demand sectors in Viet Nam are operating with obsolete technologies. Rehabilitating and replacing these existing technologies are potential measures for saving energy and for reducing the pollution emissions, including GHGs emission.
The mitigation options or measures should satisfy the high-energy demand while reducing the GHGs emissions. The new efficient technologies on the demand side and the fuel switching options on the supply side will be the best options. Following is a list of potentially good mitigation options for the energy sector:

This study used a methodology to identify strategies that satisfy energy demand and at the same time reduces GHGs emissions for the energy sector of Viet Nam. The approach can be described as follows:
First, the Sectoral Energy Environmental Demand Analysis Model (MEDEE/S-ENV) model is used for energy demand forecasting; and Second, based on the projected energy demand, the Energy Flow Optimization Model-Environment (EFOM-ENV) is used as a tool for optimization of the energy resources while minimizing adverse effects to the environment. Evaluation is done within EFOM-ENV taking into consideration the best available technologies and associated fuel shares, for the major energy activities.
The assessment of the energy GHGs mitigation options was carried out by using the MEDEE/S-ENV and EFOM-ENV models. MEDEE/S-ENV was used to project the final energy demand. EFOM-ENV was used to optimize and to calculate primary energy requirements and the related energy production necessary to satisfy a given exogenous demand of final energy. Under this assessment, the energy emissions and cost impacts have been evaluated.
mitigation options were provided by the various institutions worlung on the development of the energy sector. The data on energy consumption and energy intensity were derived from primary sector and end use data. Long-term social economic assumptions are based on projections from the Long Term Strategy Study Institute.
The input data and variables used for the assessment of the energy sector
Energy Demand Forecast-MEDEE/S Model
The MEDEE/S model is a techno-economic model. The model is organized into homogeneous categories or modules, which enables a detailed modeling of energy demand dynamics.
MEDEE/S is made up of a basic model, which is automatically implemented for the 5 energy subsectors, and a series of annex sub-models for calculating environmental details that can be specified. MEDEE/S thus resembles a “model kit”, which each country can adapt through a user-friendly procedure to suit its own socioeconomic characteristics and data availability.

ENERGY ASSESSMENT SECTOR
The procedure used by the model for forecasting energy demand is briefly described below.
The socioeconomic system is divided into subsectors (industry, agriculture, service, transportation, and household) in which the characters of economic activities and energy consumption demand are considered. These subsectors are in turn divided respectively into homogenous groups called modules in which the characteris- tics of the energy consumption are considered identical among the consumer unit. Thus, one can apply the same structure of evalua- tion to estimate energy demand of consumer units from the same group. The estimation of energy demand from each module is broken down into two steps:
Estimate the energy demands for satisfying social needs and for conducting the defined production activities (cooking, heating, and lighting). Estimate the final energy demand from the energy consumption by calculating the actual energy consumption based on the type of energy used and power efficiency of equipment. After establishing the structure of evaluation on the energy demand for each module and integrating all the systems of power consumption, the study on the fluctuation of energy demand is made on the basis of varying scenarios.
Structure of the Viet Nam MEDEE/S Model
In the model, the energy consumption system of Viet Nam is separated into five sectors: industry, agriculture, transportation, household and commercial/service. The forecast process is applied to 4 periods 1990-1995, 1995-2000, 2000-2005 and 2010-2020.
Industry Sector:
The industry sector includes six subsectors: food industry, textile- garment, chemicals, metallurgy & engineering, building materials and others. Data of energy consumption was obtained from the Energy Institute and Ministry of Industry (MOI), and data of GDP of each sector was obtained from the statistical yearbook. On the basis of this data (year 1994), the values of electric intensity and fossil fuel intensity of each subsector in the base year was calculated. Viewed from the structure of the overall energy balance, the proportions of energy, by fuel type, used for heating in each industrial subdivision can be estimated.
Household Sector:
The whole sector is divided into two areas: rural and urban. Each area is classified into two categories: household type 1 that has an annual income less than 10 million VND (Vietnamese dong) and household type 2 having annual income higher than 10 million VND. Data on the ratio of these 2
VIET NAM
SECTION 3
types of households were obtained from the book “A Survey on the Living Standard of the Vietnamese People” published by State Planning Committee and General Statistics Office. The types of energy consumption studied in this module include cooking, lighting, and hot water. Family electrical appliances studied in detail are television, refrigerator, fan and air conditioner. The structure of energy fuel types used for cooking and lighting as well as the index of family electrical appliances is also extracted from the survey data. The consumption standards are estimated according to the average capacity of the appliances and the numbers of hours used per annum, with reference to standards of the Energy Institute.
Transportation Sector
The research takes the following transportation kinds into account: road, rail, waterway and aviation transport, in which freight transport and passenger transport is differentiated. All the data for the transportation sector are available in the “Statistical Yearbook 1995”. In combination with the data of energy consumption collected from Ministry of Transport and Ministry of Industry, energy-consumption rates for various means of transport were calculated. Data of the proportion of motor vehicles ownership were collected from the survey on the living standard of the Vietnamese people.
Agriculture Sector
The energy consumption level was calculated for the following agriculture sector demands: motor demand, heating demand and electricity demand. The demand for domestic usage of rural areas, however, was determined from the civil-domestic module. Based on the GDP of the agriculture sector and the energy consumption level in the overall energy balance, the values of basic variables for the agriculture sector were calculated. Variables estimated include electricity intensity, energy intensity of fossil fuels and energy intensity of motor fuels.
Commercial/Service Sector
Due to the lack of statistical data, the energy demand was calculated for the whole sector based on the value added that this sector contributed according to the number of employees. The data was derived from the “Statistical Yearbook, 1995”.

Energy Flow Optimization Model-Environment (EFOM-ENV)
The EFOM-ENV model that belongs to the category of medium or long-term energy system optimization modes using quasidynamic linear programming was applied in the study.
In EFOM-ENV, the energy flow begins with primary energy through energy transportation to the final energy demand. Some primary energy forms are converted to intermediate energy forms and then to final energy demand such as hydropower, fossil fuels converted to electricity, etc.
network is modeled as an oriented graph with nodes representing different energy types and likes representing conversion and emission reduction processes in between. The energy conversion and abatement technologies are described according to their technical (conversion efficiencies, installed capacities, by products, etc.), economic (investment, fixed and operating costs) and environmental aspects (emission factors characteristics).
EFOM-ENV is a quasi-dynamic model that calculates the inter-temporal development of the energy system over a planning horizon of several decades. The age structure of existing plants, the dynamics of market penetration and the development of energy demand due to the expected economic development are explicitly taken into account. In the optimization process, various options for energy supply and emission reduction based on given sets of energy technologies, energy carrier etc. are analyzed leading to optimal strategies for energy supply and emission reduction. Therefore, structural changes in the energy systems (e.g. fuel switching technology switching) are not given exogeneously, but are part of the optimal solution calculated by the model.
The EFOM-ENV model is structured in a modular manner in which the real
The main features of the model are:
Explicit representation of energy processes by unidirectional links. Links can be grouped into subsystems representing a sector or a clearly defined group of technological processes. The complete energy system network is presented by a succession of interconnected subsystems from energy reserves until the final consumption (or demand). The energy supply and demand system is presented by an integrated database that relates with the associated network model. This Energy Environment Data Base (EEDB) describes completely the energy system as well as the technical, economic and environment informa- tion in all of its parts. Emphasis on technological processes of energy supply and utilization can be explicitly presented by means of a set of
VIET NAM
SECTION 3
economic/social/environmental parameters associated with the links representing them. Optimization of the energy system can be carried out in static snapshots or dynamic (multi-period) modes using linear programming. The objective function for optimization is under full control of the user, although the most often used objective function is to minimize the total discounted energy system costs. Analytical representations of the energy generation and utilization activities with seasonal or daily load cycles such as electricity, heat, steam and gas. Environmental issues, that stem from the supply side (i.e. those related to resources extraction, energy transformation, transportation, delivery to the final consumption), can be dealt with. The impacts of policy measures (energy conservation, fuel switching etc.) implemented at the end use level can also be examined by the model. On the other hand, emission reduction measures such as fuel substitution, improvement of fuel quality, energy conservation, efficiency improvements, and emission control technologies can also be assessed with the help of
EFOM-ENV.
EFOM-ENV can provide an optimal primary energy supply mix and can estimate the capacity and investment needed to satisfy the long-term demand at the least cost. The overall discounted costs of the system are minimized which include investments, import expenditure, variable and fixed costs of all process operations of the energy chains, and the costs of emission control technologies.
On the other hand, the described methodology and its use for the elaboration of strategies for energy supply and emission reduction involve several limitations. In a linear programming model, all relations are expressed by linear functions, in spite of the fact that a number of non- linearities exist in the real energy system. A technical example of such non- linearities is the ratio of electricity and heat production of cogeneration power plant. On an economic level the “economies of scale” have to be mentioned leading to specific investment costs decreasing with the capacity installed. Furthermore, integer variables are not considered in the model, so that minimum or standard capacities of plant types cannot be adequately taken into account.
Structure of the Viet Nam EFOM-ENV Model
Model generally distinguishes between different systems. Each system comprises a set of technologies with similar function. In line with the disaggregation used for the Viet Nam 2020 program, the energy supply and demand are represented by systems as follows:
Coal svstem (COAL-SS)
The coal system comprises all conventional activities from the coal extraction with two types of mines such as open pits and deep mines to coal washing for the production of clean coal and then transport to users. The export and import of coal is also included.
VIET NAM
ENERGY ASSESSMENT SECTOR
PAGE 51
SECTION 3
PAGE 52
ENERGY ASSESSMENT SECTOR
At present, Viet Nam exports coal but the domestic demand for coal will increase rapidly, especially in the power generation sector so that domestic coal production might soon not satisfy demand. For this reason, imported coal is considered in this coal module. The structure of the coal system includes coal for coking and imported coke for industrial demand.
Oil System (OIL-SS)
This system includes all activities from extraction of crude to refining and distribution of oil products to end-users. In Viet Nam, crude oil is low sulfur light oil and there is only offshore extraction. At present, there is no refining, but according to the Viet Nam Petroleum and Gas Corporation, Viet Nam will build oil-refining plants between 2000 and 2020.
Until oil-refining plants are in operation, Viet Nam will have to import all oil products to cover its demands. After year 2000, part of oil products from domestic refineries may be exported. Associated gas is accounted for in the gas system.
Gas System (GAS-SS)
This system covers all gas related activities from natural gas extraction onshore and offshore to end-use, including intermediate processing such as production of liquefied natural gas (LNG), compressed natural gas (CNG) and liquefied petroleum gas (LPG). There is also the potential for Viet Nam to export natural gas by undersea pipeline to Thailand. This project is presently under discussion by the two governments. The associated gas from oil extraction is also included in this system.
Central Electricity System (CENTELEC-SS)
The electricity corporation of Viet Nam (EVN) is managing all the chain from power generation to distribution of the electricity to end-users. On the network side, the two electricity systems considered include (i) Northern system and (ii) Southern system.
In the Northern system, rich in coal reserves, coal-fired thermal plants will be considered. At present, hard coal is the main fuel for all thermal plants. However, in the future lignite will also be considered for use.
generating plants in the southern system. Possible energy sources include offshore natural gas in the south and coal from the north or from other Asian countries. Coal- fired, oil-fired, oil-gas fired and combine cycle power plants will be considered in the future in the Southern sub-system.
There are also hydropower plants in both systems. In addition, the two systems are connected by a high voltage 500 kV transmission line. The activities represented in each sub-system range from power generation, including fossil fuel generation and hydropower generation, to transmission, sub-transmission and distribution of electricity. The export of electricity is considered in both the northern and southern systems.
Fuel supply will be a key determinant in the future for choosing thermal
Traditional Fuel System (TF-SS)
Traditional fuels are mainly used in household sector for cooking. The two main types of traditional fuels are fuelwood and agricultural residues. They are
VIET NAM
SECTION 3
considered in this study as the combined category of biomass. This system considers the fuel chain from extraction of biomass to transport to end-users.
Industrial System (INDUS-SS)
In the industry system, energy demand consists of coal, gas, electricity, fuel oil, motor fuels and other oil products. The electricity demand of the industrial sector is received from the northern and southern electricity system.
The industrial sector is the largest energy consumer now and also in the future. At present, in the industrial production subsector, most of the equipment is outdated. Industrial equipment consumes more energy than the equipment in the developed countries, especially in thermal processes.
Household System (HH-SS)
In order to account properly for the substitution option and conservation measures inside the household system, household demand is split according to end-use application, mainly into three categories: cooking, lighting and other electrical uses. The fuel types considered for cooking are electricity, kerosene, LPG, coal and traditional fuels. The fuel types for lighting are kerosene and electricity. The final electricity needed in this sub-system is received from both the northern and southern system.
Transportation System (TRANSPOR-SS)
The energy forms in transport system are coal, diesel oil, gasoline and jet fuel. At present in Viet Nam, the railway uses coal as fuel for its steam engines. It is expected that this will be replaced by diesel engines by the year 2005.
Agricultural System (AGRICULT-SS)
In the agriculture system, energy demand includes motor fuels and electricity, which is received from northern sub-system and southern subsystem, for specific electricity uses.
Macroeconomic Assumptions
The BAU case is an extension of present trends and assumes that the efficiency of the existing energy system will remain at 1994 levels. It assumes no major change in energy policy. In this case, market forces are crucial in determining energy supply and de- mand. In the BAU case, the economic development assumed by the Development Strategic Institute, Ministry of Planning and Invest- ment is shown in tables 3.4.2.1 and 3.4.2.2 and forms the basis of the main assumptions stated below. It is estimated that Viet Nam's population will reach 82.1, 88.5, 94.4, and 107 million in 2000, 2005, 2010 and 2020, respectively. The growth rate of investment for the period 1996 to 2000 has been projected at 15 percent. In the period 2001 to 2010 and 2011 to 2020, this figure will increase according to economic targets, quality of life changes, and changes in the use of capital.

Income in the non-agriculture sector will increase from 5.5 percent per year during the period 1996 to 2000 to 9 to 10 percent per year in the period after 2000. According to the projection in agriculture sector, the annual average growth rate of the agricultural value-added will reach 4 percent to 4.5 percent during the next 15 years. Industry and construction - The annual average growth rate of the industry and construction sector will reach about 11-14 percent in the period 1996-2010 and 10 percent in the period 2011-2020. It is difficult to measure the growth rate of the service sector in com- parison. However, the development of industry and agriculture lead to the development of services. A reasonable annual growth rate of the service sector will range from 8.5 to 10 percent. This is based on an annual growth rate of 44.5 percent in the agriculture sector and 14 percent in the industry sector for the first 10 years followed by 12-13 percent for the period 2010 -2020.

Energy Supply Assumptions
The main principle of the strategy for reducing pollution emissions on the supply side is to reduce fossil fuel usage by improving energy efficiency, substituting fossil fuels by non-fossil fuels, and replacing with high-carbon- content fuels with low-carbon-content. Viet Nam’s energy development is summarized as follows:
In construction of future thermal power plants, priority should be given to the development of larger units with higher efficiency than current plants. In the future, transmission and distribution networks should be rehabilitated. A standard medium voltage level of 22 kV should be used for reducing transmission and distribution losses. It is assumed that oil refinery plants will be constructed and oper- ated by 2000 mainly for the domestic market. Oil products are

considered only while there will be surplus over the domestic demand.
BASE Case Assumptions
(i) Macroeconomic Assumptions
Hypotheses regarding population growth, and GDP growth and structure are the same as in the BAU case.
(ii) Mitigation options in Supply Sectors
Fuel Switching in Power Generation
This emissions abatement option involves fuel switching in the power generation sector. In the north, existing coal-fired power plants are substituted by oil-fired power plants; in the south, existing oil-fired power plants are substituted by gas-fired thermal power plants.
The capacity of existing coal-fired power plants to be converted to oil use is 640 MW in the period 2000 to 2005. The investment requirement is estimated to be about $150/kW. The capacity of existing oil-fired power plants to be converted to gas use is 198 MW in the period 2000 to 2005. The investment requirement is estimated to be about $l00/kW.
Wind Turbine
The technical viability of operating wind energy systems depends on the available wind velocity and duration. Viet Nam, particularly the central region, is in a high wind-velocity area. However, wind energy use is still very limited, and is used mainly in remote areas. Some foreign companies have proposed new wind farms for Viet Nam. The Ventis Company conducted a feasibility study for the construction of a wind farm with a capacity of 10MW in a first phase and 20MW at the end of the second phase in Nha Trang city, in southern Viet Nam. The first phase is expected to be in operation by year 2000, and the second phase is expected to start operation in 2005.
installed wind power capacity is as follows: This study considers wind power growth starting in the 2000, and the

Mitigation Options in Demand Sectors
The final energy demand of the BASE case assumes efficiency improvements in the industrial sector, in coal cooking stoves, and in household electric appliances.

Efficiency Improvements in Cooking
Energy for cooking in Viet Nam is dominated by biomass fuels. In rural areas, fuelwood is used for cooking. Some kerosene is also used. Coal, either in lump form or as briquettes, is widely used. The share of electricity for cooking is very small.
The change from burning lump coal in homemade stoves to burn briquettes in innovative stoves leads to an efficiency increase from 17 percent to 25 percent. The cost of efficiency improvements in a cooking stove is estimated to be $50/ktoe saved. Penetration rates of this efficiency improvement in milestone years are assumed as follows:
2000 2005 2010 2020
Rural households, percent 5 10 15 20
Urban households, percent 10 15 20 30
Compact Fluorescent Lamps (CFLs)
Lighting in Viet Nam is currently provided predominantly by mercury vapor lamps. Fluorescent lighting is rarely used, and incandescent lighting is used in outlying areas. There is a large potential for application of CFLs in Viet Nam. This option entails installation of CFLs in place of existing lamps. The schedule for this substitution is as follows:
2005 2010 2020
Rural households, percent 0 3 5
Urban households, percent 10 15 20
Characteristics of incandescent bulbs currently in use and CFLs can be described as follows:

Nominal power capacity, W 75 14
Lifetime, hours 1,000 8,000
Capital cost, $ 0.5 20
Annual consumption, kWh 109.5 23
Based on these figures, cost of substituting CFLs by bulbs is estimated to be $31/MWh saved.

High-Efficiency Refrigerators
The Institute of Energy, through surveys carried out by Market Research of the Energy Institute, estimated that refrigerators in Viet Nam represents about 3 percent of residential peak demand in the winter and 5 percent in the summer. However, this market is growing very rapidly.
Estimated power consumption of refrigerators range from 100W to 135W. In this study, the figures and characteristics were taken from a World Bank demand-side management analysis. They are related to 150-liter refrigerators with a 120-W capacity. The compressor operates an average of 14 hours per day, resulting in an annual electricity consumption of 613 kWh. This emissions reduction option assumes that existing standard refrigerators will be replaced with efficient ones. Characteristics of both standard and efficient refrigerators are listed below:

Lifetime, years 8 8
Capital cost, $ 350 385

The schedule for substitution is as follows:

Rural households, percent 5 10 15
Urban households, percent 15 20 30
Based on the above figures, the cost of substituting efficient refrigerators for standard ones is estimated to be $63/MWh.
Air Conditioning
At present, electricity consumption for air conditioning in Viet Nam is estimated (in the World Bank DSM Analysis Report) to be 3 percent of total electric consumption. This share will be higher in the future due to the construction of new modern buildings and improved living standards. This study considers replacement of existing air conditioners (from the former Soviet Union) with more efficient ones. Average annual electricity consumption of existing air conditioner is estimated at 1,987 kWh per year. With efficient air conditioners, electricity consumption is expected to be reduced by 22 percent. The characteristics of the two models of air conditioners are below:

Urban households, percent 15 20 30
The cost for substituting efficient air conditioner by efficient air conditioners for standard one is estimated to be $9/MWh.
More Efficient Industrial Motors
Establishment of an electric motor efficiency standard would capture opportunities that would otherwise be lost during the intense industrial growth period that is expected in Viet Nam. Highly efficient electric motors are available from the majority of large electric motor manufacturers in industrialized countries.
This emission reduction option considers savings improvement based on a 15-kW motor, which is the average motor size in the 0.75 to 150 kW motor range. For this average size, a 5 percent efficiency improvement based on an 86 percent standard efficiency motor results in energy savings of 6.4 percent. The energy consumption and incremental cost are shown below:

The Abatement Case Approach
a. First Approach
The first approach involves setting CO2 emissions constraints at the end of the study period, i.e. in 2020. Different levels of CO2 emissions reduction are considered. The least-cost solution will indicate energy supply technologies that meet the final energy demand and CO2 emissions constraints at the same time.
This approach defines potential CO2 emissions reduction in 2020 to 5 percent, 10 percent, or 15 percent compared to base emissions.
b. Second Approach
This approach limits CO2 emissions at the same levels as the first approach but according to a yearly growth rate during the study (2005 and 2020) compared to CO2 emissions in the Base case. Growth rates for CO2 emissions are 0.5 percent, 1 percent, and 1.1 percent per annum.
Final energy demand for the study period was given in section 3.4.2. Final energy demand input for optimization of the energy supply system (from EFOM-ENV) is summarized in Table 3-17.
Primary Energy supply
Figure 3-9 shows the development of the primary energy supply in Viet Nam in the BAU scenario. As a result of increase in energy demand, total primary energy supply in 2020 will be about 6.1 times as high as demand in 1990. This corresponds to an average annual growth rate of about 7.2 percent.
Domestic coal production will increase gradually with an average growth rate of 8.5 percent in this study period resulting from increased industrial and power generation demands. However, the share of coal production will decrease from 27 percent in 1994 to 14 percent in 2020. The annual average growth rate will be about 4.6 percent during the study.

Natural gas penetrated the market in 1995 and will increase until 2020 as it is used for power generation. The share of natural gas will increase to about 11.9 percent in 2020 from 7.8 percent in 1995. In terms of absolute value, natural gas increases from 1,700 ktoe in 2000 to 9,590 ktoe at the end of the study period; i.e., the average growth rate is about 9 percent per year. Development of hydropower has also been promoted. Hydropower supply has increased in recent years and continues to grow during the study period at an average of 7.4 percent per year until it reaches 13,650 ktoe.
In order to meet the high-energy demand, nuclear power plants will be constructed in 2020. However, the share of nuclear power will still be small at 5 percent in relation to total primary energy supply. Geothermal and wind power will be used for power generation, but their share in total primary energy is small.

Power Generation
Because of high electricity demand growth, power generation is expected to rise drastically. Electricity production in 2020 will be more than 13 times than that in 1994. This corresponds to an average growth of 11 percent per year during the study. Electricity production reaches 152 TWh in 2020 up from 11 TWh in 1994. Electricity production by hydropower plants dominates accounting for about 50 percent of this total during the study period. Figure 3-10 illustrates electricity production by fuel types in milestone years.
power industry is gas fueled combined cycle plants. Electricity generated from this technology will account for 36 percent of total electricity generation from thermal power in 2020.

During the study period, fuel input for electricity generation will increase from 3,072 ktoe in 1994 to 29,705 ktoe in 2020. (Table 3-22, Fig 3-11)
Hydropower dominates power generation during the study period. The share of hydropower in the total fuel input for electricity production is at its maximum at 69 percent in 1994, and then decreases to 46 percent in 2020. It is clear that natural gas is the preferable fuel for power generation in the least-cost solution. The share of natural-gas-based electricity in total electricity production ranges from 29 percent to 32 percent, growing at an annual rate of 10.5 percent.

By contrast, the contribution of oil products will decrease in the fuel mix for electricity production in the year 2000. Replacement of oil will be largely a result of increased use of natural gas and hydropower for electricity generation. Figure 3-13 shows the fuel mix in electricity production in the BAU case.
Table 3-23 illustrates the power generation by technologies in a least cost option. It is clear that electricity generation will come mainly from hydropower, which accounts for 74.6 percent of total electricity generation in 1994 and 39.8 percent in 2020. In 2020, more than 40 percent of total electricity generation will come from gas combined cycle. The coal-fired power plants share of electricity generation will be about 16 percent in 2020. The shares of other new and renewable energy technologies, such as wind power, geothermal power, and biomass, will still be small in the least-cost power supply mix,

CO2 Emissions
CO2 emissions will increase rapidly in the future mainly because of growth of primary energy consumption and increasing use of coal. Total CO2 emissions are projected to increase from 22 mt per annum in 1994 to 197 mt per annum at the end of study period. This corresponds to an average growth rate of 8.8 percent per year in the BAU case.
Table 3-25 illustrates CO2 emissions by sectors. The contribution of industry to total CO2 emissions is largest in the BAU case. The share of CO2
emissions from industry is projected to increase from about 36 percent in 1994 to 44 percent in 2020; while the share of the tertiary sector will drop from about 20 percent in 1994 to 9 percent in 2020 in the BAU case in the study period. The share of CO2 emissions from the power sector ranges between 10 percent and 20 percent in the BAU case.
declines slightly from 28 percent to 22 percent over the period 1994 to 2020 in the BAU case. The agriculture sector will continue playing very small role in the total CO2 emissions due to its very small share in the total final energy demand.

Natural gas penetrates the market mainly from 2000 and will increase drastically in the period 2000-2020 due to the introduction of gas into power generation. The share of natural gas will increase to about 12.3 percent in 2020 from 8.18 percent in 2000. In absolute value terms, natural gas would increase from 1,700 ktoe in 2000 to 9,590 ktoe in the BASE scenario at the end of study period, i.e., average growth rate will be about 9 percent per year.

The development of hydropower production would also be promoted. The supply of hydropower has increased in recent years and will continue to increase in the study period at 8.5 percent per year of average growth rate and will reach 13,648 ktoe in the BASE scenario in 2020 (Table 3-33). However, the share of hydropower will be the range of 18-23 percent in the primary energy supply during the study period. In 2020, in order to meet the high-energy demand, nuclear power plants will be constructed. However the share of nuclear power would be still small in total primary energy supply, with about 5 percent in 2020.
but their share in total primary energy is still small.
Power Generation
Geothermal power and wind power will be used for power generation
Due to the high growth rate of electricity demand, power generation is expected to rise drastically. The electricity production in 2020 would be more 11.2 times than that in 1994. The electricity production reaches 11,706 GWh in 1994 and up to 131,251 GWh in 2020.
Table 3-31 illustrates the power generation by technologies at a least cost option. It is clearly that electricity generation will mainly from hydropower, accounting for 74 percent in 1994 and 42 percent in 2020 in total electricity generation. In 2020, more than 41 percent of total electricity generation will come from natural gas combine cycle power plants. The share of electricity generation of coal fired power plants will increase to about 14 percent in 2020 compared to 4.1 percent in 2010. The other new and renewable energy technologies such as wind power, geothermal power and biomass are included in the least cost power supply mix which is expected to provide a small share of the power. Hydropower is the most favorable primary energy for power generation until 2020.

Hydropower is the most favorable primary energy for power generation until 2020. However, the share of hydropower in total energy input for production of electricity reaches a maximum at 69.3 percent in 1994 and then declines to 45.9 percent in 2020. Natural gas for power generation increases with an annual average growth rate at 9 percent in the period 2000-2020. The share of coal increased drastically from approximately in 9.9 percent 1994 to 19.2 percent in 2020. The substitution of oil in year 2000 is mainly due to an increased use of natural gas and hydropower for electricity generation (Tables 3-33 and 3-37).

Comparison of BAU and BASE Cases
The comparison of primary energy supply in the BAU and BASE cases is illustrated by Figure 3-23. By enhancing energy conservation measures in energy use, the primary energy supply can be reduced. In 2020, the reduction of primary energy supply in the BASE case is about 3.2 percent compared to the BAU case. Most of the primary energy deduction is coal, while other energy supply is the same as the BAU case.

Other Mitigation Scenarios
First Approach
The first approach is designed based on the reduction of CO2 emissions from the results given in the Base case. The reduction rate is set in year 2020 for three levels: 5 percent, 10 percent and 15 percent compared to the Base case. The three abatement cases are set respectively as ABAT01 (optionl), ABAT02 (option2), and ABAT03 (option3).
Primary Energy Supply
The ABAT01 case, with the CO2 emissions reduction rate of 5 percent in 2020 compared to the Base case, leads to the substitution of nuclear power for coal. The share of primary coal supply in the Base case is 21.2 percent in 2020, while nuclear power accounts for only 0.72 percent in the same year. By setting the constraint to abate 5 percent CO2 emissions from energy activities in 2020, the least cost solution selects less coal (18.45 percent) and more nuclear power (3.07 percent) than in the Base case to satisfy the final demand. The shares of the other primary energy in the total primary supply remains unchanged compared to the Base case.
The ABAT02 case assumes a 10 percent CO2 emissions reduction as compared to the Base case. The result is a variation in coal and nuclear power similar to that seen in ABAT01. In this case 27.7 percent of coal reduction compared with the Base case is substituted by nuclear power. It can be observed that coal share is reduced while the nuclear power share increases. The results show that coal will account for 15.5 percent of the total primary energy supply and nuclear power 5.4 percent in 2020.
percent CO2 emissions reduction, the energy substitution is between coal and natural gas, and nuclear power. In comparison with the Base case in 2020, use of coal is reduced by 30 percent, and 22 percent of natural gas is replaced by nuclear power. The nuclear power option accounts for 9.6 percent of the total primary energy supply. Table 3-40 and Figure 3-26 illustrate the primary energy supply for this and the other scenarios.
Electricity Generation
In the ABAT03, due to the more stringent constraint in 2020 of a 15
The optimization results of the different levels of constraint on CO2emissions show that the most affected energy related activity is the power generation sector. The least cost solution adopted by these abatement cases is fuel switching in the power sector.
In the Base case, the least-cost solution without CO2 emissions constraints show that 36.3 percent of the electricity generation comes from combined cycle gas plants, 14.5 percent from coal plants, while nuclear power accounts for only 1.9 percent in the total electricity generation in 2020.
In the ABAT01 case, the results show a reduction of electricity generation by coal of 9.4 percent and an increase of electricity generation by nuclear power of 9.1 percent.

The power generation from other sources of energy remains at almost the same level as compared with that of the Base case.
from energy related activities as compared to the Base case. As a result, coal will not be used for electricity generation. At the same time, the share of electricity generation by nuclear power increases to 28 percent while the share from natural gas is reduced to 30.3 percent by 2020.
Table 3-41 shows, for the first approach, the shares of the power generation by the various technologies under these three scenarios.

Second Approach
In the second approach, the CO2 reduction is set to decline from the year 2000 at three levels: 0.5 percent, 1 percent and 1.1 percent per annum as compared to the Base case. These three scenarios are established as ABAT04 (opt4), ABAT05 (opt5), and ABAT06 (opt6).
Primary Energy Supply
The ABAT04 case, with the CO2 emissions reduction rate of 0.5 percent per annum as compared to the Base case, leads to the substitution of nuclear power supply for coal supply. By setting the constraint to abate 0.5 percent CO2 emissions during 2000 to 2020 from energy activities, the least cost solution to satisfy final demand results in less coal and more nuclear power than in the Base case. The shares of the other primary energy in the total primary supply remain unchanged compared to the Base case.
The ABAT05 case sets the CO2 reduction rate to 1 percent per annum compared to the Base case. In the ABAT05 case, the main variation is the greater substitution of nuclear power for coal based power as seen in the ABAT04 case.
In the ABAT06 case, due to a more stringent constraint on CO2emissions of 1.1 percent per annum, nuclear power is substituted for not only coal but also natural gas power plants as well. The least cost option results in a reduction of 29.1 percent of coal and 30.5 percent of gas use in comparison with the Base case in 2020. The resulting nuclear power option accounts for 10 percent of the total primary energy supply. Figure 3-30 illustrates the primary energy supply in the second approach.
Electricity Generation
In the ABAT04 case, the results show the reduction of electricity generation by coal and the increase of electricity generation by nuclear power for the period 2005-2020. The share of electricity generation by coal

ranges from 11.6 percent in 2005 to 14.9 percent by 2020 in the Base case and is expected to be reduced to 7.8 percent in 2005 and 5.3 percent by 2020 in this case. While the share of oil fired power plants for total electricity generation increases from 3.6 percent in 2005 and 2.2 percent in 2010 in the Base case to 5.9 percent in 2005 and 3.6 percent in 2010 in this case. In 2020 the reduction of electricity generation by coal will be replaced by nuclear power (2.0 percent in the Base case compared to 11.4 percent in the ABAT04 case).
power plants will be reduced rapidly from 7.8 percent of total electricity generation in 2005 to 0 percent in 2020, while 28.1 percent of electricity generation is expected to come from nuclear power in 2020.

Comparison of Approaches to CO2 Constraints
The key difference between the approaches presented in this section consists in the way CO2 emissions abatement constraints are applied over the study period. In the first approach, CO2 constraints are applied only at the end of the study period (i.e., in 2020) and several cases are analyzed depending on the level of the CO2 emissions abatement constraint applied (i.e. 5 percent, 10 percent, and 15 percent CO2 reduction compared to the BASE Case). In the second approach CO2 emissions abatement constraints are applied all along the study period between 2000 and 2020 (i.e., at 0.5 percent, 1 percent and 1.1 percent per year CO2 emissions abatement as compared to the BASE Case).
The results of the first approach show that the CO2 emissions reduction appears only in the last period of the study (i.e. 2015-2020), whereas in the second approach CO2 emissions reduction is gradual from 2000 until 2020.
In the first approach, the modifications of the primary energy structure and of the power sector (fuel and technologies) happen only in the last period under study (i.e. 2015-2020). However, in the second approach, the primary energy structure and the power sector show regular changes all along the study period (2000 to 2020). In terms of the final structure of the Power sector in 2020 in the most extreme (stringent) cases in both approaches (i.e. ABAT03 and ABAT06), small differences appear as shown in Tables 3.4.5.14 and 3.4.5.15. In terms of CO2 emissions abatement, both cases (ABAT03 and ABAT06) correspond to a similar CO2 abatement rate of around 15 percent in 2020 compared to the BASE Case.
The approaches correspond to different policy strategies. The first approach consists in limiting GHG emissions on the basis of a given target year (i.e. 2020), while the second approach corresponds to imposing a gradual abatement of CO2 emissions on the energy sector activities.
Scenarios for Specific Mitigation Options
There were seven specific technical options assessed for least-cost mitigation: two energy supply options and five energy efficiency options.
(i) Efficient Coal Cooking Stoves (ENV-1)
The ENV-1 option considers the efficiency improvement of coal cooking stoves. The average efficiency of existing coal cooking stoves is estimated to be 17 percent. It is assumed that it is possible to increase the efficiency up to 25 percent. The incremental cost of the efficiency improvement is estimated at about $50 per ktoe of saved coal.
mt. The incremental cost of avoided CO2 mitigation is –$4.15 per t. The least-cost results show a potential cumulative CO2 mitigation of 73
(ii) Compact Fluorescent Lamps (ENV2)
The ENV-2 option proposes to replace incandescent light bulbs (ILBs) by energy-efficient compact fluorescent lamps (CFLs). Average power consumption of the existing bulb is about 75W and electricity consumption is about 110kWh per annum. CFLs use roughly 80 percent less electricity but CFLs are more expensive than ILBs. The lifetime of CFLs is estimated to be 8

times more than that of ILBs. However the cost of CFLs is higher than that of IBLs.
mitigated with an incremental cost of –$8.31 per t of avoided CO2 emissions from switching to CFLs.
The EFOM-ENV model results indicate a potential 16 mt of CO2
(iii) Energy-efficient Refrigerators (ENV3)
The ENV-3 option relates to better marketing of energy-efficient refrigerators to replace existing refrigerators. The average refrigerator efficiency assumed results in a unit consumption of 521 kWh/year or about 85 percent of the energy consumed as compared to the old refrigerators.
incremental cost of –$8.53 per t of avoided CO2. The modeling results show a potential 88 mt of CO2 reduction with an

cost of -$10.54 per t avoided CO2. The results show a potential 52 mt of CO2 reduction with an incremental
(v) High Efficient Electric Motors (ENV5)
The ENV5 option considers the replacement of existing motors with energy efficient motors. It is assumed that the average efficiency of standard electric motors can be improved by at least 5 percent from 86 percent to 91 percent.
incremental cost of avoided CO2 for this option was estimated to be -$7.19 pert of CO2.
The results indicate a potential CO2 mitigation in the order of 70 mt. The
(vi) The Fuel Switching in Existing Thermal Power Plants (ENV6)
The ENV6 option considers the substitution of coal by oil in existing thermal power plants in the north and oil by gas and increasing gas used in generation of existing thermal power plants in the south. In this scenario primary energy supply is not much different when compared with the Base scenario. The share of fuel oil in total fuel for generation is higher than that of the Base scenario, while the coal share is lower.
The switching from coal to oil in the north and oil to gas in the south for power generation reduces GHGs emissions in very large amounts. The total GHGs (CO2) emissions of this scenario will be 14 mt CO2 with an incremental cost of $46.4 per t of avoided CO2.
(vii) Wind Power Plants (ENV7)
Wind power is a new energy technology and also a new concept in Viet Nam. In the past, small stand-alone wind power stations for battery charging were used for low power needs such as lighting and telecommunication.

They are most likely to be installed in remote islands as cheaper alternatives for diesel generator sets.
The total GHGs (CO2) emissions for this option is 34 mt CO2 with an incremental cost of -$4.64 pert of avoided CO2.
Table 3-43 presents a summary of the differences in cumulative costs and emissions of the seven mitigation options considered. The mitigation options lead to savings in CO2 emissions of between 5 and 88 mt. Similarly, the incremental costs vary from option to option. Six out of the seven options can be implemented at negative incremental costs.
their incremental costs per t of CO2 reduced. Energy efficient air conditioners followed by energy efficient refrigerators and compact fluorescent lamps are most cost effective in reducing CO2 emissions. Figure 3-34 shows that in total more than 333 mt of CO2 can be reduced at negative incremental costs by implementing the six most cost-effective mitigation options.

CERI Curve by Reduction of CO2 Emissions Growth Rate
The First Approach
In the BAU case, the final energy demand was projected based on economic development indicators by the MEDEE/S model. The primary energy supply was calculated to meet the demand optimized by the EFOM- ENV model. The total CO2 emissions in 2020 are expected to be 197 million ts. Discounted cost of the whole study period is about $34,354 million.
EFOM-ENV model with the improvement of efficiency in energy use. The total CO2 emissions of the optimal solution is 189 million ts, 4.2 percent less than that of the BAU case. The discounted cost is expected to be $33,447 million. Cost for reduction of 1 t CO2 emissions is calculated at – $109.
CO2 emissions abatement at 5 percent, 10 percent, and 15 percent in 2020 compared to the BASE case, the CO2 emissions will be reduced by 9.0 percent, 13.8 percent, and 18.4 percent compared to the BAU case respectively. The discounted cost of the ABAT01 case will be higher than that of the BASE case but lower than the BAU case. The incremental cost of the ABAT01 case is –$31 per t avoided CO2 emissions in comparison with the BAU case, while those of ABAT02 and ABAT03 are $3.88 per t avoided CO2 emissions and $4.87 per t avoided CO2 emissions respectively. Table 3-44 shows CO2 emissions and total discounted cost in first approach and Table 3-45 presents the CO2 emissions abatement and incremental cost in the first approach.

The total CO2 emissions reduction in the whole study period compounds to 13 percent by ABAT01, 17.5 percent by ABAT02, and 18.7 percent by ABAT03, compared to the BAU case. The discounted cost of ABAT04 and ABAT05 cases will be higher than that of the BASE case, but lower than the BAU case. The incremental cost of the ABAT04 case is – $1.47 per t avoided CO2 emissions, and that of the

The results in Tables 3.4.6.3 and 3.4.6.5 show the cumulative abatement of CO2 emissions corresponding to the first and second approaches. The results are generally higher in the first approach than in the second approach for an equal level of CO2 emissions abatement. For example, the CO2 abatement for the study period is 254 (10 percent), 348 (14 percent) and 442 (18 percent) mt of CO2 in ABAT01, 02 and 03 respectively as compared to 172 (7 percent), 256 (10 percent) and 276 (11 percent) million ts of CO2 in ABAT04, 05 and 06 respectively. When looking at the costs of emissions reduction (in $ per t of CO2 abated), it is interesting to note that the abatement options corresponding to both approaches are similar when comparing them on an equal basis of CO2emissions abatement. For example, the BAT05 case (which corresponds to a 10 percent abatement of CO2 emissions) has an abatement cost of –$0.88 per t. This is comparable to the ABAT01 case (which also corresponds to a 10 percent abatement of CO2 emissions) results in an abatement cost of –$0.85 per t). In both approaches, when CO2 abatement requirements increase to a certain limit, the abatement costs become positive indicating an increased positive cost

related to these abatement options. That is, the more stringent the CO2 emissions abatement, the higher will be the cost.
The main difference between both approaches resides in the way CO2 emissions abatement is applied to the energy system. In the first approach we look at abating CO2 by year 2020. In the second approach, CO2 emissions abatement is progressively applied from 2000 up to 2020. The second approach is probably more realistic in terms of environmental policy as the investments in CO2 emissions abatement will be progressively done throughout the study period. The first approach assumes that all the investments will be done only during last period of the study (i.e., 2015-2020). This is clearly less desirable.
In Viet Nam, the technologies on both the supply and demand sides are very old and obsolete. The priority of energy efficiency improvement has been considered as a strategy of development. Any measure or action to be implemented in order to increase energy use efficiency will have positive economic and environmental effects.
reducing GHGs emissions, but the investment costs for these options are higher than others. Hydropower will be one of the most reliable initiatives. The environmental cost of hydropower schemes in term of land loss and resettlement requirements are considerable and there is some evidence that these have been underestimated. There may be also environmental benefits from hydropower projects arising from improved conditions for river traffic and from the cleaner and more regular flows of water downstream of reservoirs. The balance of these impacts is not an easy matter.
From the results of this project, preliminary estimates for some of the options are provided, especially for environmental impacts. A detailed socioeconomic and environment impacts assessment should be implemented for specific projects.
Switching to low or non-GHGs emitting fuels is an effective measure for

The energy sector is one of the most important motive forces of economic development in Viet Nam. The high growth rate of the economy requires to the use of more energy. To support economic growth, primary energy supply should be adequate to meet energy demand.
(i) The final energy demand of Viet Nam over the next two decades will be expected to increase dramatically. Final energy consumption in 2020 is projected to be 6-7 times hgher than in the base year 1994. As a result, GHGs emissions will dramatically increase at both the sectoral and national level.
(ii) The industry sector will play a dominant role and will be responsible for more than 50 percent of the total energy demand in 2020. The GHGs mitigation of the industry sector is significant. The improvement of efficiency in industrial production in order to reduce energy con- sumption and GHGs emissions will be one of the most effective ways for GHGs abatement.

(vi) The best prospects for reduction of GHGs emissions are expected in the power generation sector. These include options such as the transformation of existing coal and oil fired thermal plants to use of natural gas, the construction of new combined cycle power plants, and construction of hydropower plants.
(vii) Many mitigation measures including switching to renewable energy will result in both national and global environmental benefits.

There are some differences in the data provided by different sources, especially the data of long-term projections. The measures to overcome constrains that were identified during the project require upgrading the ALGAS country team with sector experts, and establishing a national and provincial network for further studies and data collection.
(x) The information relating to the world market for environment-friendly technologies is insufficient. This lack of information limits the number of technical options that were assessed. International cooperation and communication should be upgraded to help obtain more reliable information for the future.
(xi) The knowledge and recoption of the need for abatement of GHGs emissions by policy makers and planners is a very important factor for successful implementation. The least-cost strategy developed by the ALGAS Project can serve as input for policy formulation.

SECTION 4FORESTRY AND LAND-USE
CHANGE SECTOR ASSESSMENT
iet Nam has a total land area of 33 million hectares (mha), and it lies between latitudes 8o35' N and 23o24' N. About 19 mha, accounting V for 58 percent of the land area of Viet Nam, are classified as forestland.
Half of that area, 9.3 mha are dense forests. Most of the other half is covered by bush or open tree stands, but some bear almost no vegetation at all. The only large areas of natural forest remaining are located in the highlands of southern Viet Nam and are evergreen or semi-deciduous, often dominated by dipterocarp species. These forests constitute the most valuable wood resource of the country and will continue to do so well into the next century.
Forestland in Viet Nam is divided into three categories: (i) Special use forest, (ii) Protection forest, and (iii) Production forest, and each of these covers only a part of the area. The forest use classification provides a broad structural basis for the description of primary forest values. The Special use class recognizes scenic, amenity, scientific, and cultural values. Forests in the Protection class have, primarily, watershed and coastal protection value. The Production class includes forest types capable of yielding wood and other forest products.
summarized in Table 4-1. The areas of forest type and forest use classes in Viet Nam are

The areas under different forest categories in 1993, according to the Forestry Science Institute, Ministry of Agriculture and Rural Development, are shown in Table 4-2.
The forestry sector is critically important in the social and economic development of both urban and rural communities, and the success of general development strategies will depend to a considerable extent on how the forest resource is being managed. The forestry sector in Viet Nam contributes about 3 percent to the GDP. In global terms, the forestry sector offers a number of options for reducing GHGs, particularly carbon, emissions. According to preliminary estimates by the Intergovernmental Panel on Climate Change (IPCC) Working Group II (1996), between 1995 and 2050 about 60 to 90 Gt of carbon emissions could be reduced or sequestered through slowing deforestation, establishment of plantations, agro-forestry, and forest regeneration. Thus there is a large potential to reduce carbon emissions through forestry sector abatement strategies.

According to the Forest Inventory and Planning Institute (FIPI), the achievements of the national reforestation program are impressive, with recent annual planting of about 125,000 ha. However, it is clear that the reforestation accomplishments have been lower than expected. The natural forests are shrinking in area due to shifting cultivation and clearing for permanent agriculture, and they are also being degraded through unsustainable exploitation for logs and fuelwood. Deforestation continues to be a serious problem of the country. It is estimated that the rate of annual forest loss is at about 150,000 ha. This problem needs to be solved in the years to come.
This chapter discusses several key issues related to: (i) sector emissions inventory; (ii) sector mitigation analysis; and (iii) assessment of different strategies and development of the least-cost strategy.
Forests are both a source and a sink of carbon dioxide, which is the GHGs most associated with the forests. Activities such as forest land conversion and exploitation of forests lead to the emissions of CO2 into the atmosphere, whereas the planting of forests sequesters CO2. The 1993

National GHG inventory in Viet Nam shows that the total GHGs emitted from the forestry and land use change sector was about 31.3 million tonnes (mt) in CO2-equivalent, accounting for 25.4 percent of total of GHG emissions in the country. Forest conversion is one of the major causes of forest loss in Viet Nam. It is estimated that around 0.5 mha of forestland is converted annually by clearing of forests for agricultural use or shifting cultivation in Viet Nam.
Under the Asian Development Bank’s Regional Study on Global Environment Issues, the 1990 National GHGs Inventory has been carried out based on the OECD method. Under the ALGAS Project, the most recent National GHGs Inventory has been carried out by the Institute of Meteorology and Hydrology (IMH), Hydrometeorological Service (HMS) of Viet Nam, in cooperation with the Forest Science Institute (FSI), Ministry of Agriculture and Rural Development (MOARD). The IPCC method was used for this inventory. At the time of inventory, 1993 was selected as the year to represent the period in which Viet Nam’s economy system is transforming from a planned to a market-oriented economy. Moreover, the newest official data that could be used for this inventory were from 1993. Thus, 1993 was chosen as basic year for the inventory.
Viet Nam used the standard IPCC methodology for emissions inventory in the land-use change and forestry sector. The major spreadsheets of the IPCC methodology included the following submodules.
(i) 5.1 Changes in forest and other woody biomass stocks
This submodule deals with the emissions or sequestration of carbon (and carbon dioxide) due to change in forest and other woody biomass stocks affected by human activity.
(ii) 5.2 Forest and grassland Conversion
In this submodule, total carbon emissions from deforestation or forest clearing is calculated through the main activities such as burning of aboveground biomass on site, decaying of timber biomass used off site, and decomposition of aboveground biomass on site.
(iii) 5.3 On-site burning of forests (for trace gases)
This submodule deals with the emissions of CH4, CO, N2O, and NOx due to on-site burning of plant residues after deforestation. The method of calculation is very similar to that of non-CO2 trace gases from burning of traditional biomass for energy.
(iv) 5.4 Abandonment of managed lands
This submodule deals with removals of CO2 resulting from the natural regeneration of forest in abandoned farmland or degraded forest, as well as dry tropical forests. The activity involved is annual carbon uptake by aboveground biomass in abandoned farmlands and dry tropical forests.

Changes in Forest and Other Woody Biomass Stocks
As mentioned in Section 4.1, areas under different forest categories in Viet Nam in 1993 are shown in Table 4-2. Three main categories are: (i) Plantations, (ii) Natural forests, and (iii) Savannas. These area data were used for estimating total carbon content in annual growth of forests. In addition, dispersed trees (e.g., urban, village, farm trees) were added for this estimation. It is estimated that more than 1.2 million dispersed trees were planted in the country in 1993. Total annual growth increment or carbon uptake increment by forest/biomass stock was about 30.78 Tg carbon.
According to the MOARD, total biomass consumption in the year 1993 was about 32,316 kt dry matter (dm), of which wood consumption for commercial and other purposes was 3,643 kt dm and for fuel was 28,672 kt dm. Wood removed in forest clearing was 1,372 kt dm. Therefore, the total biomass consumption from stock would be about 30,944 kt dm. As a result, annual carbon release from total biomass consumption from the stocks was 15.47 Tg C. Net carbon uptake could be estimated by subtracting the annual carbon released from the total annual carbon uptake. Total carbon uptake due to changes in forest and other woody biomass stocks is shown in Table 4-3.

3 Net Carbon uptake 15.31
Forest and Grassland Conversion
This category includes conversion of existing forest and natural grasslands to other land uses, such as agriculture. In order to estimate amount of carbon emissions due to forest and grassland conversion, three sets of calculations have been used:

It is estimated that about 448 kha of forests including 420 kha of dry forests were converted, mainly for agriculture purposes, in the inventory year. Three activities causing GHGs emissions from forest and grassland conversion are (i) on-site and off-site burning of biomass, (ii) decomposition process, and (iii) soil. Total carbon released from forest and grassland conversion is presented in Table 4-4.

Total GHG Emissions from Land-use Change and Forestry Sector
Emissions from the sector were calculated, according to the method proposed by IPCC, for the year 1993. Total of CO2 emissions (excluding non- CO2 GHG emissions) from the sector was more than 29.8 million t, including the following sources:
(i) Changes in forest and other woody biomass stocks, (ii) Forest and grassland conversion, and (iii) Abandonment of managed lands.
Although 57.2 Tg of CO2 was removed from the atmosphere by these forestry activities, the sector still contributed 29.9 Tg of CO2 (excluding non- CO2 GHG emissions) to the total of national GHG emissions in 1993. Table 4-6 shows the total carbon dioxide uptake/emissions from the sector in 1993.

SECTION 4 FORESTRY AND LAND-USE CHANGE
SECTOR ASSESSMENT
The main factors contributing to the estimated carbon emissions in the sector are deforestation and forest degradation, including shifting cultivation, and clearing for agricultural purposes in the country. With three million people practicing shifting cultivation, forests are still the main source of fertile land for cultivation of essential food crops, and this causes forest degradation in Viet Nam. In addition, in order to satisfy short-term needs and create immediate benefits, forest resources are being exploited heavily. It is estimated that more than 30 Tg of wood in dry matter is being extracted from forests annually. This factor also leads to forest loss in the country.
CO2 emissions from the forestry and land-use change sector in 1993 was 29.8 Tg excluding non-CO2 gas emissions (trace gases). The sector accounted for about 25 percent of national CO2 emissions. Figure 4-1 illustrates the percentage of total GHGs emissions (in CO2-equivalent in different sectors in Viet Nam in 1993.

The land-use change and forestry sector has a large potential for reducing GHG emissions through enhancing carbon sinks in the country as well as protecting the environment. The 5-year plan of the Viet Nam Government sets several targets for protecting the existing natural forest areas as well as forest plantation. One target is to develop watershed protection forest and plantation in order to increase forest coverage rapidly to over 40 percent of the land in the next decade. It is also proposed to accomplish the promotion of sedentary farming and settlement throughout the country by the year 2000.

The Government plan for the forestry sector (as given in Table 4-7) and the Master Plan of the MOARD were the references used to develop GHG emissions projections in the sector. Figure 4-2 presents CO2 emissions projections made for Viet Nam up to year 2020. CO2 emissions are projected to decline from 29.8 Tg in 1993 to 4.2 Tg in the year 2000. However, no net emissions are projected for the years 2010 and 2020. Instead a net sequestration of 21.7 Tg by 2010 and 28.4 by 2020 are projected. This projected reduction in CO2 emissions (or in fact net sequestration) is mainly due to the large projected increases in plantation area as well as conservation of natural forests (Table 4-7).

biomass. This is critical for Viet Nam because there are about 1.1 mha of bamboo forests with five main species that have completely different stem morphologies. Given the importance of bamboo in the Viet Nam economy, mitigation assessment in this ecosystem requires a better method for estimating the bamboo emissions/uptake.

the land-use change and forestry sector, the sector contributed 25 percent of total GHGs emissions in the country.
In order to implement the inventory, the IMH, in cooperation with FSI and other concerned agencies, made efforts to collect both activity data and data that describe various biological and chemical parameters associated with land use. However, several data were difficult to gather or measure, so IPCC default values were used for estimation of CO2 emissions/uptake in the sector.
For updating the GHGs inventory for future, it is necessary to :
(i) study the approach and methods of IPCC guidelines; (ii) strengthen the GHGs inventory team, including key persons from
several institutions such as General Statistical Office, Development Strategy Institute, Forestry Inventory and Planning Institute, and MOARD;
(iii) verify and improve GHGs source and sink coefficients. Particularly, improve estimated coefficients for forestry and land-use change activities proposed by the IPCC, and evaluate the applicability of these coefficients to known or expected Viet Nam conditions.
(iv) develop a National GHGs Inventory Plan focused on implementation of the first National Communication on GHGs Inventory and those carried out in 1998. The base year for the next inventory will be 1994.
Forests and forestland occupy about two-thirds of the total area of the country. It is a main asset and provides most of the work opportunities for more than 24 million people belonging to some 50 ethnic groups, who live in or close to the forests. Forests and forestland are also most important factors contributing to environmental balance.
vegetation of Viet Nam was estimated at 14.3 mha in 1943, corresponding to a forest coverage of 44 percent (Project VIE88 - 037,1991). From LANDSAT satellite image interpretation, the results of the inventory in 1993 indicated that the area covered by woody vegetation (tree species and bushes) was 9.3 million ha, corresponding to a forest cover of 28 percent (FIPI, 1993).
During the past five decades, Viet Nam’s forests have degraded. The forest
Causes of forest loss in the country are:
Heavy exploitation of the forest resources. Shifting cultivation practiced by about 3 million people living in mountainous areas or highland. Forestland conversion to cultivated land due to population growth and illegal immigration. Forests were also destroyed because of chemical warfare. It’s estimated that about 1.2 mha were lost in the 1960s and 1970s.
The Viet Nam Government has made strong efforts in both reducing deforestation and increasing reforestation in the country in the past 30 years. With a number of forestry projects, including the achievements in tree planting, forest protection, fixed cultivation, and encouragement of sedentary farming and settlement, during recent years losses of forest have been reduced. Deforestation now stands at about 100,000 ha a year, down by 50 percent from previous levels.

SECTION 4
In order to restore forests and enhance carbon sinks in the forestry sector, there are many measures that require different investments as well as certain socioeconomic conditions.
The national GHGs inventory in 1993 showed that the GHGs emissions, including non-CO2 trace gases (in CO2 -equivalent terms), from the forestry and land-use change sector accounted for 25.4 percent of the total GHG emissions (in CO2-equivalent terms) in Viet Nam. Although there was an uptake of 57 Tg CO2 by forest vegetation, a number of activities such as clearing forest, shifting cultivation, logging, etc., led to 87 Tg CO2 emissions into atmosphere. As a result, the total net CO2 emissions in the sector was 29.9 Tg, accounting for one-third of the total CO2 emitted in 1993.
Developing and assessing feasible forestry GHGs mitigation options is one of main tasks of the ALGAS Project in Viet Nam. The COMAP model has been used for developing and evaluating forestry GHGs mitigation options.
According to Viet Nam’s forestry condition, in order to enhance carbon pools as well as to meet biomass demand in the country, four main mitigation options have been considered.
(i) Reforestation. (ii) Enhanced natural forest regeneration. (iii) Forest protection. (iv) Scattered tree planting.
Forestry mitigation options have been matched with land categories in the country. Table 4-8 describes the area under each land category actually suitable and available for the forestry mitigation options.

In recent years, the rate of reforestation increased from year to year. Every year 100,000 ha of forest and 500 million scattered trees are planted. As a result, the deforestation rate is now reducing by 50 percent from the previous level.

Up to the year 1996, the reforestation rate is greater than deforestation. According to the Government plan, 5 mha of forest will be planted during 1996 - 2010 (MOARD, 1997). Besides, a policy named “Stop logging in natural forests for a given period” will come into effect soon. Under this policy, such activities as logging, timber, etc. would be strictly banned in the areas of natural forest. Therefore, the rate of natural regeneration will be increased dramatically in the next period.

1. The Comprehensive Mitigation Analysis Process (COMAP) model is used for developing and assessing forestry mitigation options. The steps are:

(iv) Estimate the potential for bioenergy-technology-based bioelec- tricity generation for a given extent of land availability and efficiency of conversion, as well as estimate carbon emissions avoided and the potential for fossil fuel electricity substitution through generation of bioelectricity (BIOENER model).
In order to provide information on the financial costs, net present value (NPV) of benefits of forestry options, and changes in carbon stocks annually under different scenarios, REFOREST and FORPROT models were applied, in which 1994 was chosen as a base year. Activity data was mainly collected from General Statistical Office and Forest Science Institute, Forest Inventory and Planning Institute- MOARD, and Development Strategy Institute - Ministry of Planning and Investment (MPI). The costs and inputs used in the COMAP for each option are given in Appendix A4-6, while the COMAP outputs are presented in Section 4.3.4.
(3) Several forestry options were developed and evaluated in an attempt to reduce sources of GHGs and to maintain and expand sinks of GHGs in the country. In all analysis, a value of 10 t/ha for the wasteland was used to estimate dry weight of vegetation carbon with carbon density of 0.5, and a value of 50 tC/ha was assumed for amount of carbon stored in the soil. For the mitigation, values of 0.65 tC/ha-yr for reforestation, 0.5 tC/ha-yr for scattered trees, and 1 tC/ha- yr for enhanced natural regeneration were used to define amount of carbon stored in soil. A value of 5 years for the decomposition period and a value of 10 tC/ha-yr for the amount of decomposition carbon were used. For discount rate, a value of 10 percent was applied.
Recently, a plan was developed by the Vietnamese Government in which

and Table 4-9. From a GHGs accounting perspective, forestry options can be divided into three classes of benefits:
(i) Reduce sources of GHGs. (ii) Maintain sinks of GHGs. (iii) Expand sinks of GHGs.
The forestry mitigation options aim at carrying out reforestation and forest protection at the country level in the attempt to reduce carbon emissions as well as enhance carbon sinks. Enhancement of natural regeneration and protection of degraded forests would also be potential options.
To slow the deforestation rate, as well as meet a part of local biomass demand, the scattered tree planting option was developed and assessed. However, it is noted that it will be very difficult to meet the Government’s targets, in which 5 additional ha of new forest will be established by 2010 and most existing natural forests will be protected by 2020. Therefore, the Government plan is considered as a Technical Potential scenario. The two other scenarios: (i) Baseline and (ii) Feasible scenario were also developed and assessed. The three scenarios will be discussed in section 4.4.2
COMAP models are used as analytical tools for assessing the performance, costs, and benefits of the mitigation options, as well as for estimation of the emissions reduction or carbon sequestration potential per unit area of each mitigation option.
One of the main steps of the forestry options assessment is to estimate land availability in the country for each forestry option. Table 4-8 in Section 4.3.1 shows potential areas available for the options. However, due to several reasons such as socioeconomic conditions, financial sources, feasibility, etc., only a part of the available areas may be used for forestry mitigation options. With regard to forest protection, apart from a few areas of natural forest in high mountain or remote areas, almost all natural forests face deforestation. Thus, nearly all existing natural forests need protecting. This becomes more suitable when the policy “Stop logging in natural forests for a given period” comes into effect soon.
The categories of mitigation options and the size of the area allocated for each option annually under the feasible scenarios are shown in Table 4-10.
Five forestry mitigation options are developed under the feasible scenario as follows:
(i) Enhanced natural regeneration of 1.85 mha of degraded forest areas. (ii) Reforestation of 2.2 mha, including 1 mha under long rotation and 1.2
mha under short rotation. (iii) Protecting 6.5 mha of existing forests. (iv) Planting 4 billion scattered trees.
By implementing the above options, the forestry sector could increase forest coverage from 26 percent at present to 45 percent by the year 2020.
COMAP models are used for assessing and evaluating forestry mitigation options under three scenarios based on different silviculture measures. The forestry mitigation options have been developed relating to reforestation,

enhanced natural forest regeneration, scattered tree planting, and forest protection in the country in the period 1994-2020.
Under the feasible scenario, the long rotation reforestation option showed the lowest mitigation potential with 67.5 Tg C abated whereas the existing natural forest protection option demonstrated the greatest potential, with 680.2 Tg C abatement, accounting for 69 percent of total carbon abated.
As can be seen from Table 4-11, it is found that forest protection is the option with the lowest endowment cost and the highest mitigation potential. In term of present value of benefit, apart from the long rotation reforestation option, the other four options have a positive value, in which the highest value is estimated for the scattered trees option, with the benefit of $409 per hectare. The long rotation reforestation option gave a negative net present value (NPV) because of the long period of investment, low domestic market price, and the Government’s recent policy to ban raw wood export. Thus, wood prices in the country may be affected in the next decades.
For investment cost, the enhanced natural regeneration and existing natural forest protection options required lower costs, while the reforestation options with both long and short rotation required higher cost (Table 4-11). Figure 4-3 illustrates the mitigation potentials of the options in terms of total of carbon abated per hectare. Figure 4-4 shows the life-cycle cost ($/tC abated) required to implement the each option until 2020.
the lowest life-cycle cost with the value of $0.4 /tC abated. On the contrary, the short rotation reforestation option (SRR) required the highest life-cycle cost with the value of $3.5 /tC abated.
under both baseline and technical potential scenarios, 11 forestry options, including 5 options of the baseline scenario, were developed and assessed through COMAP model. The total area under each option and its COMAP outputs are presented in Table 4-12.

In order to analyze forestry mitigation options at the country level along with the relevant environmental aspects and financial benefits, the COMAP models were utilized.
The two models: (1) FOR - PROT and (2) REFOREST of COMAP models were used in Viet Nam. FOR - PROT model was utilized for assessing the potential and cost-effectiveness of forest protection options while REFOREST model was applied for assessing the potential and cost-effectiveness of reforestation options under both long and short rotation periods. It was also used for evaluating enhanced natural generation and scattered tree options. All forestry options under Baseline, Technical Potential, and Feasible Scenarios were developed and analyzed through the model.
In general, the models are useful for assessing the mitigation potential of the forestry sector through a set of identified forestry mitigation options. However, several values inputted into the COMAP model, such as soil carbon densities and the rate of carbon accumulation under different forest areas, should be verified and improved for the next study.
So far, there are four activities conducted in the forestry sector in Viet Nam, namely reforestation/afforestation, natural regeneration, forest protection, and scattered tree planting. Based on Viet Nam's socioeconomic conditions and the rate of forest rehabilitation, the following scenarios have been developed.
(1) Baseline scenario: It is assumed that the rate of annual forest rehabilitation during the period 1994-2020 would be 100,000 ha, approximating the average rate of forest rehabilitation in the last ten years. The rate of deforestation would be 50,000 ha per year, down by 50 percent from the existing level. The survival rates for reforesta- tion programs vary. However, in the COMAP analysis it was assumed that the survival rate was 100 percent. For forest protection activities, under this scenario only 2.4 mha of existing protection forests shall be conserved in the period.

5 million additional ha and 6 billion scattered trees would be planted in the country in the next decade, in an attempt to increase the cover rate of forest and perennial trees from 28 percent at present to 45 percent in 2010. The rate of reforestation would be 300,000 ha per year. Deforestation would be stopped by means of implementing the “Forest-door closure” policy in which logging, timber, etc. in existing natural forests will be prohibited in a given period. In addition, 3.1 mha of degraded forests would also be protected, and 2.7 mha of degraded forest areas would be under natural regeneration.
(3) Feasible scenario: Under this scenario, levels of implementation of several forestry options are assumed to be higher than in the Baseline scenario but lower than in the Technical potential scenario. This scenario, actually, is considered to be more feasible than the technical potential scenario because of several existing socioeco- nomic and technological conditions in the country. It is assumed that the rate of reforestation would be about 140,000 ha per year and 4 billion scattered trees would be planted during the period of 1994-2020, while 6.5 mha of exiting natural forests would be protected. In addition, about 1.9 mha of degraded forest areas would be under enhanced natural regeneration in the whole period.

For the Baseline scenario, as mentioned in the previous section, the government policy is assumed to be implemented, in which 5 million additional ha and 6 billion scattered trees will be planted by 2010. However, if the government policy is used as a baseline, no additional mitigation actions can be taken for many years to come. The Baseline scenario, in Viet Nam’s case, is considered as the Likely trends scenario. Under this scenario, the rate of annual reforestation would be about 100,000 ha until 2020, approximating the average rate in the last 10 years. The survival rates for reforestation programs were assumed to be 100 percent in the COMAP analysis. However, the deforestation rate would continue to be on the average of 50,000 ha per year over the period 1994-2020. As a result, the area of existing forests, particularly natural forests, would reduce from 8.2 mha in 1994 to 6.9 mha in 2020. The following forestry options were developed under the Baseline scenario and were assessed by the model.
(i) Enhanced natural regeneration of 1.1 mha of degraded forest areas including 0.6 million ha of young and mixed forests (ENR1)
(ii) Reforestation of 0.8 mha of degraded forest areas under 27-year rotation period (LRR1)
(iii) Reforestation of about 1 mha of degraded forest areas under 10-year rotation period (SRR1)
(iv) Conservation of 2.4 mha of protection forests (FP1) (v) Planting 3 billion scattered trees (ST1)
The Technical Potential scenario was developed based on the Government’s policy. In fact, in the past 30 years, areas planted in trees total about 1 mha. Deforestation still remains a problem which must be solved in the coming years. Thus, it is very difficult to achieve goals of the policy by 2010. The policy, however, can be considered as a Technical potential scenario in Viet Nam. Under this scenario, 6 forestry options were developed and analyzed by the COMAP model.
(i) Enhanced natural regeneration of 2.7 mha of degraded forest areas including 0.6 mha of young and mixed forests (ENR2)
(ii) Reforestation of 1.4 mha of degraded forest areas under 27-year rotation period (LRR2)

COMAP results for the options developed under both the Baseline and Technical Potential Scenarios are presented in Table 4-11.
A number of mitigation options could be assessed based on several criteria such as available land areas, socioeconomic situations, and political conditions. In general, both baseline and mitigation scenarios depend on the demands exerted on the forest resources of both wood products and other land uses.
Under the Feasible scenario, the rate of reforestation would be about 140,000 ha per year in the period of 1994-2020. Protection of 8.4 mha of existing forests, including 1.9 ha of degraded forests under enhanced natural regeneration, would be included in this scenario. Four billion scattered trees would be planted by 2020. The forestry mitigation options under this scenario are developed as follows:
(i) Enhanced Natural Regeneration (ENR3)
Since this option will carry out enhanced natural regeneration of 1.85 mha of degraded forest areas, including 400,000 ha of young and mixed forests, the estimated NPV of benefits will be $0.8/tC or $34.2/ ha. There can be abatement of 87.3 Tg of carbon emissions.
(ii) Long Rotation Reforestation (LRR3)
Each year, 40,000 ha of waste or degraded lands will be planted with a 27-year rotation period. Under this option, 1 mha will be developed into forest plantation resulting abatement of 67.5 Tg of carbon emissions while NPV of benefits will be $ –1.2/tC or $ –55.5/ha.
(iii) Short Rotation Reforestation (SRR3)
Each year, 90,000 ha of waste or degraded lands will be planted with a 10-year rotation period. Under this option, 1.2 million ha will be reforested, resulting an abatement of 71.7 Tg of carbon emissions, while NPV of benefits will be $9.9/tC or $353.9/ha
(iv) Forests Protection (FP3)
This option will conserve 6.5 mha of existing natural forests. The estimated NPV of benefits will be $0.8/tC or $85.3/ha. Under this option, there can be abatement of 680.2 Tg of carbon emissions.
(v) Scattered Trees (ST3)
This option will plant scattered trees at the average rate about 60,000 ha per year in equivalent. The estimated NPV of benefits will be $9.2/tC or $409.1/ha. Under this option, there can be abatement of 79.9 Tg of carbon emissions.

SECTOR ASSESSMENT
A number of cost-effectiveness indicators generated by the model, such as NPV of benefits, initial cost, mitigation potentials, and life-cycle cost for each above option can be found in Table 4-11.
GHGs emissions/removal from the forestry sector has been estimated for the period 1993-2020, based on master plan of MOARD and the recent government plan. By carrying out several low-cost and most effective mitigation options, the sector will play an important part in reducing total CO2 emissions as well as enhancing carbon sinks in the country.
Generally, implementation of the scenarios has a positive impact on socioeconomic conditions. It can provide employment for local people as well as attract them to reforestation and forest protection activities. It is estimated that about 350,000 people can be employed under the Baseline scenario. The employment potential of the Feasible scenario is estimated at 616,000 people, and it is estimated that 912,000 local people can be provided with employment under the Technical Potential Scenario.. This means that the scenarios, in the attempt to halt deforestation in forest and mountainous areas, can generate income for the poor, particularly for several ethnic groups who are living in the forests and practicing shifting cultivation.
With regard to the environment, the implementation of reforestation, afforestation, enhanced natural regeneration, and forest protection will contribute an important part to conservation of water resources, biodiversity, and improvement of soil condition.
The COMAP outputs indicate that the amounts of carbon abated under the Baseline, Technical Potential, and Feasible scenarios in the period 1994- 2020 would be 469 Tg, 1,433 Tg, and 987 Tg, respectively. Total areas required for planting, regeneration, and protection in the period would be 6.4 mha, 19.0 mha, and 12.2 mha for the Baseline, Technical Potential, and Feasible scenarios, respectively. The life-cycle costs required would be about $380 thousand million for the Baseline scenario, $1,019 thousand million for the Technical Potential scenario, and $657 thousand million for the Feasible scenario. (Table 4-14). The source of investment funds can be from financial benefits generated by baseline activities in the sector. Besides, funding can also be obtained from the State budget for reforestation and forest protection programs in the years to come, supporting the attempt to increase forest areas in the country up to 14 mha by 2010.
From the three scenarios, it can be seen that most forestry options have positive present value of benefits, excluding long rotation reforestation options. It means that the activities can generate benefit to compensate cost. In terms of life-cycle cost, it was found that forest protection has the least cost at $ 0.4 per t of carbon abated in the three scenarios. The relationship between cumulative carbon abatement and cost per t carbon abated under the three scenarios is presented in Figure 4-5.

In order to assess cost-effectiveness of the forestry mitigation options under the Feasible scenario, the values of NPV were calculated in terms of t of carbon abated per ha under each option. Priority of those options has been identified. The best NPV ($/tC) is given by the short rotation reforestation option (SRR3) with $9.87/tC, the scattered trees option (ST3) comes in second ($9.22/tC), the forest protection option (FP3) takes the third place ($0.81/ tC), and the enhanced natural regeneration option (ENR3) comes in fourth ($0.78/tC). The long rotation reforestation option (LRR3) gave a negative value of –$1.23/tC.

By implementing the identified mitigation options under the Feasible scenario, the cumulative mitigation potential will be 987 mt of carbon (Figure 4-6). Cumulative life-cycle costs required for adopting the scenario will be $657 million, whereas cumulative NPV of benefits for about 12 mha under this scenario will be $1,679 million. The least-cost strategy for the scenario is given in Figure 4-5c.
Under the Feasible scenario, NPV of benefit obtained by the scattered trees option is the highest with a value of $695 million, while the long rotation reforestation is the opposite with a value of –$56 million. The forest protection option has the highest mitigation potential with 680 mt carbon abated, accounting for nearly 70 percent of the total carbon abated for the scenario. Actually, the option becomes more feasible in the nation because of the recent government policy aimed at conserving existing natural forest in the years to come, in the attempt to protect environment as well as reduce the impacts of climate change.
Figure 4-7 illustrates the total cumulative carbon abated against the cumulative NPV of benefits, while Figure 4-8 illustrates the total cumulative carbon abated against the cumulative life-cycle costs required for adopting the Feasible scenario.

The forestry sector has the potential to reduce GHGs emissions and enhance carbon pools in the country. Based on the recent plan of the Government as well as Viet Nam’s socioeconomic conditions, the forestry least-cost GHGs abatement strategy in the period 1996-2020 was formulated. Goals of the strategy are as follows.
Establish a system of protection forest, covering about 8 mha, for the purpose of protecting existing natural forest watersheds, preventing soil erosion, and enhancing carbon sinks. Establish a system of special-use forest, covering about 2 mha, for use as national parks, forest reserves, and cultural sites. Establish 11 mha of production forests. By the year 2010, most of the necessary exploitation would come from planted forests with
Create 5 mha of new forest, in which 1 mha should be established
By extending the forested area as indicated above, the rate of forests coverage should increase to 45 percent of the land surface of the country, leaving only a little hill land bare of tree cover.
only a minor share coming from the natural forests.
by using intensive methods to obtain high productivity.
Short-term (1998 - 2005)
The rate of reforestation is planned to reach about 140,000 ha per year, an increase of 30 percent as compared with the average annual reforestation rate in the past 5 years. In addition, about 1.5 billion scattered trees will be planted and 6.5 mha of existing natural forests will be protected. At the same time,
VIET NAM
SECTION 4
natural regeneration will be allowed in 1.8 mha of degraded forests. As a result, there will be about 1 mha planted in forestland by 2005, contributing to reduction of GHGs emissions from the sector.
Medium-term (2005 – 2015)
Continuing to carry out forest protection options will maintain and improve the important carbon sinks in the country. The average annual reforestation rate will be reduced gradually. From 2005, about 100,000 ha of forest and 200 million scattered trees will be planted annually. It is estimated that by 2015, more than 2 million additional ha would have been planted since 1997, including 1.2 mha of protection forests.
Long-term (beyond 2015)
The rate of reforestation will be 160,000 ha per year. About 1 mha of wasteland will be revegetated by 2020. Natural forests will be protected for the whole period. Before 2020, a number of forest products such as roundwood, timber, etc. from established plantations and some natural forests would be harvested to meet the in-country demand as well as wood export.

FORESTRY AND LAND-USE CHANGE
SECTOR ASSESSMENT
The result of the 1993 National GHGs Inventory indicate that the main factors contributing to forestry sector carbon emissions are deforestation and forest degradation, including shifting cultivation and clearing for agricultural purposes. In 1993, Viet Nam’s forest was able to uptake 57.2 Tg CO2- equivalent, while the emissions was about 87.1 Tg, excluding non-CO2 GHGs emissions. Total net CO2 equivalent emissions, including non-CO2 trace gases, was 31.2 Tg. It was estimated that net CO2-equivalent emissions would be about 4.2 Tg in the year 2000. However, in the sector no net emissions are projected in the future. Instead, a net sequestration of 21.7 Tg CO2 and 28.4 Tg CO2 are projected in the years 2010 and 2020, respectively. This projected reduction in CO2 emissions (or in fact net sequestration ) is mainly due to the large projected increases in plantation area and conservation of natural forests in the country.
So far, deforestation continues to be a serious problem that must be solved in the years to come. In order to stop logging and maintain existing carbon sinks, forest protection options become more important in the country. The options are considered to be more feasible under the recent policy of the Government aimed at conservation of existing natural forests. Actually, the forest conservation option is normally assessed as the lowest cost and most effective way of reducing carbon emissions.
For the ALGAS study, three scenarios were developed. The Baseline scenario is considered as a Likely trends scenario, whereas the Technical potential scenario is based on the Government’s policy relating to reforestation, afforestation, and natural forest protection in the nation in the next decades. The Feasible scenario, consisting of five mitigation options, is suggested and analyzed. Generally, all of the forestry options under the scenarios were developed and assessed by the COMAP model.
Baseline, Technical Potential, and Feasible scenarios in the period 1994-2020 would be 469 Tg, 1,433 Tg, and 987 Tg, respectively. The NPV of benefits would be $1,009 million for the Baseline, $2,638 million for the Technical Potential, and $1,679 million for the Feasible scenario.
required the total cost of about $657 million, while the total cost required under Baseline scenario is $380 million. However, the implementation of the scenarios has a positive impact on socioeconomic as well as environmental issues. It can provide employment for local people as well as attract them to reforestation and forest protection activities. It is estimated that about 350,000, 616,000, or 912,000 local people could be provided with employment under the Baseline, Feasible, or Technical Potential scenarios, respectively. For environment aspects, reforestation, afforestation, enhanced natural regeneration, and forest protection options will contribute an important part in conservation of water resources, biodiversity, and improvement of soil condition.
Baseline scenario are projected to decline, and in fact there will be a significant carbon sink creation even under the Baseline scenario, due to forest conservation and considerable afforestation planned by the Government.

iet Nam is an agricultural country, and 80 percent of its population is involved in agriculture. The sector contributes nearly one-third of the V total Gross Domestic Product (GDP). Agricultural land is about 7.3
mha or 22 percent of the country’s total land area of 33 mha. The Viet Nam agricultural economy is based on food crops, industrial
crops, and livestock husbandry. Within the agriculture sector, the cultivation subsector takes the major part (proportion of production, 73.5 percent in 1993), while livestock husbandry constitutes the rest (Table 5-1).
Food crops, including paddy/rice, maize, sweet potato, cassava, and potato are of predominant importance in Vietnamese agriculture (Table 5-1). This subsector as a whole made up 47 percent of the total GDP of the agriculture sector in 1995 and is the major food source for the people. Gross output of food crops in paddy equivalent increased from 21.5 mt in 1990 to 27 mt in 1995. Paddy, the staple food of the population and one of the major export commodities, is dominant among food crops. Paddy output increased from 19.2 mt in 1990 to 23.5 mt in 1994 and to 25 mt in 1995.
Industrial crops include perennial crops such as rubber, coffee, coconut, and tea, and annual crops such as groundnut, sugarcane, and soybean. Some of these crops are important export commodities.
The livestock subsector has also grown fast in recent years supported mostly by domestic demand (Table 5-1).

The agriculture sector is an important source of GHGs emissions. Most of this is methane and nitrous oxide. Significant reduction in CH4 emissions from agriculture can be achieved through improved nutrition of ruminant animals and better management of paddy rice fields. Additional CH4 decreases are possible by altered treatment and management of animal wastes and by reduction of biomass burning.
Emissions of GHGs in the agriculture sector is primarily of methane from paddy fields and from livestock (including enteric fermentation and manure management). Nitrogen fertilizer used to increase crop productivity is a source of nitrous oxide emissions, while field burning of agricultural residues and prescribed burning of savannas are sources of CH4, N2O, NOx, and CO2.

Meteorology and Hydrology in collaboration with the National Institute for Agricultural Protection and Planning. This inventory is based on the base year of 1993, because was the most recent year for which good data were available for GHGs estimation. This year is also representative of the time of the transition economic situation in Viet Nam.
The primary GHGs emissions from livestock is methane, produced from digestive processes, mainly in ruminants, and from animal manure. Enteric fermentation in herbivores produces methane as a by-product of the digestive process. Methane emissions from enteric fermentation and animal manure is estimated according to IPCC (1995), Tier 1 methodology.
Anaerobic decomposition of organic material in flooded rice fields produces methane, which escapes to the atmosphere primarily by transport through the rice plants. The quantity of methane emitted is believed to be a function of rice species, number and duration of harvests, soil type, water management, fertilizer use, and temperature. Recently, experts agreed that the relationship between CH4 emissions and soil temperature as presented in the IPCC Guideline (1995), was no longer appropriate, because new data suggest that the seasonally integrated CH4 flux depends much more on the input of organic carbon, the water regime, time and duration of drainage, and soil type, etc., than on the local temperature. The emissions of methane from rice fields is calculated as follows
Fc = Ef x A x 10 -12
Where:
Fc is the estimated emissions of methane from a particular rice water regime and for a given organic amendment, in Tg. Ef is the seasonally integrated emissions factor and per cropping season, in gm-2. A is the annual rice-cultivated-area under these conditions and per cropping season, in m2.

The emissions factors given in Table 5-2 for calculation are those for inorganic fertilizer use. However, there are two different kinds of fertilizers used in the South and the North of Viet Nam. In the South, where 61.6 percent of the country’s rice fields are located, only chemical fertilizers are applied, while organic + chemical fertilizers are used in the North of Viet Nam (38.4 percent total of country’s rice fields).
organic + chemical amendment, a correction factor of 2 (range 2-5) must be applied to the coefficient for the corresponding rice ecosystem without organic amendment. The total emissions from rice paddy in Viet Nam, calculated by this method, are presented in Table 5-3.

Release of non-CO2 trace gases from savanna burning.
The estimation of GHGs emissions from prescribed burning of savannas is based on the IPCC 1995 guideline. There are two kinds of savanna in Viet Nam, shrub savanna and grass savanna, covering 308 kha and 88 kha, respectively. The biomass densities of the two types of savanna are 40 t dry matter per hectare on shrub savanna and 30 t dm/ha on grass savanna. These local data were obtained from the Institute of Forest Science, Ministry of Agriculture and Rural Development.
Field burning of agricultural residues and release of non-CO2 trace gases.
The estimation of GHGs emissions from on-site burning of agricultural residues is based on the IPCC 1995 method, with the assumption that the total carbon released is a function of the amount and efficiency of biomass burning. The carbon content of the biomass non-CO2 gas emissions was estimated by applying the emissions ratio of CH4 and CO to the total carbon released. Similarly, the emissions ratios of N2O and NOx are based on the total nitrogen released.
The rice production data were obtained from the National Statistical Office. The assumption regarding the fraction of crop residue burned in the field was derived from the default factor for developing countries.
The data for animal population come from the annual statistical reports of National Statistical Office. The numbers of livestock and poultry in Viet Nam, 1993, are presented in Table 5-4.
The data sources for rice paddy under various water management regimes are based on statistical material from the National Institute for Agricultural Planning and Projection-Ministry of Agriculture and Rural Development (MOARD). These materials define three categories of rice fields in Viet Nam: continuously irrigated, rainfed, and deep-water rice with water depth ranging between 50-100 cm.
The local data for burning savanna come from the Institute of Forest Science (MOARD).
The principal agricultural residues burned in the field are from the residues of rice straw. The rice production data were obtained from the National Statistical Office. The assumption regarding the fraction of crop residues burned in the field was derived from the default factor for developing countries.
The inventory of agricultural soil is based on the data of fertilizer consumed by crop type provided by the National Institute for Agricultural Planning and Projection - MOARD.

SECTION 5
The summary of Viet Nam's emissions of GHGs from the agriculture sector (CH4, CO, N2O, and NOx) during 1993 is presented in Table 5-5. The major emissions in the agriculture sector consist of CH4 (2247 Gd/year), followed by CO (975 Gg/year), NOx (24 Gg/year) and N2O (3Gg/year).
Methane
The crop cultivation subsector is the major source of methane emissions, with rice cultivation contributing 78 percent of the total (1,755 Gg/year). The livestock subsector contributes 20 percent (452 Gg/year) of the total emissions. Within the livestock subsector, enteric fermentation is the most important source, contributing 73 percent, while the remaining 27 percent comes from manure management. Biomass burning from savanna and agricultural residues emit only 1 percent of the methane (24 Gg/year and 16 Gg/ year). The major regions of savanna burning (shrub and grass) are the Central and the North of Viet Nam, while the burning of agricultural residues is practiced mainly in the South of Viet Nam.
Carbon Monoxide
The source of CO emissions is biomass burning of savanna and agricultural residues. Both are comparable in rates with total emissions of 975 Gg/year. The prescribed burning of savannas is the more important of the two types of biomass sources (65 percent).
Nitrogen Oxide (NOx)
Emissions of NOx from burning of savanna are 11 Gg/year and from agricultural residues are 14 Gg/year.
Nitrous Oxide (N2O)
The total emissions of N2O is estimated at 3 Gg/year by using the medium default values of emissions coefficients from the IPCC methodology, 1995. Agricultural soil is the most important source of N2O emissions, contributing 79 percent of the total N2O emissions. The remaining 21 percent are from biomass burning in prescribed burning of savanna (9 percent) and burning of agricultural residues (12 percent).

Rice cultivation is the greatest emitter of CH4; however, its contribution would decrease from 78 percent of the total in 1993 to 68 percent in 2020, while the contribution from livestock will increase from 20 percent in 1993 to 30 percent in 2020 (Table 5-7).
5.2.6 LIMITATIONS OF THE GHGs INVENTORY DATA
5.2.7 CONCLUSIONS
PAGE 142
The method for estimating emissions from enteric fermentation in cattle requires data on the population of various animals and the average emissions factors (kg CH4/head-year). However, the available data are insufficient for calculating the GHGs emissions accurately and for designing a mitigation strategy. The available data do not provide key information such as demographic characteristics of the population (e.g., age, weight, geographic distribution, and sizes of livestock) and the other variables related to emissions factors (e.g., feed intake and the conversion of feed energy to methane).
The method for estimating emissions from rice cultivation requires information about water management practices, season length, and fertilizer practices. Besides these, other information about rice cultivation practices, cultivar types, soil types, etc., should be collected and analyzed to ensure an accurate projection and inventory.
need to be initiated in the country: For improving future GHGs emissions inventories, the following activities
Collecting detailed data at the province level. Carrying out experiments to measure methane emissions from rice paddy under different cultivation practices in order to improve the emissions factors for rice cultivation related parameters. Carrying out household surveys in key areas for the livestock population characteristics. Collecting the data on low-methane-emitting rice varieties when available.
(i) The agriculture sector emits the largest quantities of GHGs in Viet Nam. In 1993, the total emissions were 2,247 Gg of methane emis- sions and 3.22Gg of N2O emissions, which equal 48 mt of CO2- equivalent.

The agriculture sector inventory revealed that 76 percent of total CO2-equivalent is produced from rice cultivation, and 20 percent is produced from the livestock subsector (Table 5-8),
(ii) To improve the accuracy of the GHGs emissions inventories, there is a need to carry out surveys and collect the detailed data of animal population and cultivation practices, including the data on low methane emitting rice varieties. Furthermore, there is a need to organize the measurement of methane emissions from rice paddy under different cultivation practices.
(iii) For updating the GHGs inventory in Viet Nam, the action plan proposed is as below:
Organize a study of the approach and methods of GHGs inven- tory according to IPCC guidelines. Test the confidence and applicability of GHGs inventory process, methods, and emissions factors provided by IPCC. Carry out experiments to determine some emissions factors relevant to Viet Nam. Establish an Office of GHGs Inventory. Undertake necessary efforts to bring out the first communication of the national GHGs inventory.
Greenhouse gases emitted from the agriculture sector in 1993 were equivalent to 48 mt of carbon dioxide. Agriculture produced 2.2 mt CH4 in 1993, accounting for 87 percent of total CH4 emissions of the country. The most significant sources are rice cultivation (78 percent of total CH4) and livestock (20 percent of total CH4) (See Tables 5-6 and 5-7). The inventory provides information to be used in deciding where mitigation should be focused and what abatement strategies need to be developed and implemented.
for mitigating greenhouse gas emissions, as presented in Table 5-9. Several potential GHGs abatement options exist in the agriculture sector

However, two of the options in Table 5-9 have been identified as the most promising options:
(i) Water management in irrigated rice paddy fields. (ii) Rational feeding of livestock.
These mitigation options meet the following general guidelines for the agriculture sector:
For the remaining options, (i) Changing the cropping pattern, (ii) Directly sowing, (iii) Using biofertilizers, and (iv) Using biogas, because of insufficient data, the assessment of these options has not been considered.
Agricultural production levels will be maintained or enhanced in the country. Additional benefits will accrue to the farmer (e.g. reduced labor, reduced or more efficient use of inputs). Local consumers will accept agricultural products.
The following methods have been used to assess the mitigation options in agricultural sector.
(i) To determine the investment cost, financial value, and the NPV of benefits, a bottom-up approach has been taken.
(ii) The baseline and alternative scenarios have been clearly defined. These scenarios are considered important for providing decision- makers with useful guidance on the allocation of national resources.
(iii) Sources of data.
The agricultural economic data, such as rice yield, livestock population and productivity, investment cost, the production cost, benefit value, etc. come from the Institute of Agricultural Economies (IAE). These data inputs are grouped into four main economic regions: Red River Delta, North Central Coast, South Central Coast, and Mekong River Delta
Some assumptions have been provided by IAE.

Discount rate: 10 percent The price of rice is equal to $170 per t. The investigation of practice of water management in irrigated rice fields with periodic draining showed that at two growth stages of rice crop, the end of tillering and 15-20 days after flowering, the water requirement of rice is minimum. Draining of rice fields during these two stages may lead to achieving a higher yield of rice (7-9 percent increase). At the same time, it can decrease methane emissions by 25- 50 percent. The practice of improving nutrition through increasing feed digestibil- ity, by mechanical processing and chemical processing of the feed, was found to be a feasible mitigation option in the livestock sector. This option will lead to a higher productivity among livestock (about 10 percent) and it also reduces methane emissions by between 10 and 25 percent.
(i) Mitigation option for methane emissions from rice cultivation:
In Viet Nam, agricultural production still plays an important role. According to the country Agricultural Development Plan, there is a need to achieve a production of 28 mt of food grains in 2000, 33.8 mt in 2010, and 44 mt in 2020 to guarantee food security, to provide for export, and to make strong development of breeding. In rice paddy, intensive farming techniques have to be adopted to achieve a productivity level of more than 4 t/ha-crop
At present, there is 5 mha of irrigated rice. However, the control of irrigation can be currently implemented in very small areas. The Government is providing for investments to improve the irrigation system.
Development needs to be focused on management of irrigation water, with a system of draining rice fields during the growing season, in the areas with secure irrigation supplies. These areas are the Red River Delta, the North Central Coast, the South Central Coast, and the Mekong River Delta.
The goal of this option is to control and provide sufficient water requirements for rice crops so that food production is improved and methane emissions from rice cultivation is reduced.
Mitigation of methane emissions from livestock
Animal population is expected to increase in the next few decades. There were 3.3 million cattle, 3 million buffaloes, and 15 million swine in 1993. Their population is expected to increase up to 7 million cattle, 4.5 million buffaloes, and 38 million swine in 2020.
In Viet Nam, most of the feed supplied to ruminant animals (cattle and buffaloes) is of low quality and is not subject to any form of

processing. The greatest opportunity for reducing CH4 emissions among ruminant animals is through increasing the feed digestibility through mechanical and chemical processing of the feed.
In other words, chemical and physical treatment of low quality crop residues that are fed to ruminants can enhance animal productivity and lower CH4 emissions per unit product. The treatment methods include alkali/ammonia treatment, chopping, grinding, heating, steaming, and wrapping and preserving by-products of crops such as rice, maize, and sweet potatoes.
The goals of this option are as follows:
Increasing the quantity and quality of livestock feed in order to improve the meat and milk production. Reducing methane emissions from livestock.

(i) Water management of rice fields
Rice plays an important role in the culture and diets of people of Viet Nam. The water management option for mitigating GHGs emissions in rice cultivation satisfies the criteria discussed in Section 5.3.1 and will be ecologically sustainable.
An assessment of the investment cost impact on rice yield is shown in Table 5-11. Under the baseline scenario, the baseline cost of rice is $1,052/ha- year, which includes expenses of inputs: labor, seeds, fertilizer, chemicals, electric for irrigation; and equipment, machinery, land. The baseline yield is 7,340 kg/ha-year with a financial value of $1,248/yr.

methane emissions (assumed) by 50 kg/ha-year. However, the option is more expensive than the baseline scenario by about $69/ha-year.
(ii) Improving livestock nutrition through mechanical and chemical feed processing
Improving nutrition reduces methane emissions per unit of product by enhancing animal performance, including weight gain, milk production, and work and reproductive performance. Methane emissions per unit of digestible energy consumed by animals will also be reduced.
An assessment of the investment cost and impact on animal yield are shown in Table 5-11. Under the baseline scenario, the averaged investment cost is $41/head, which includes stud animal, feed, medicine, and labor. The baseline yield is 84 kg/head-year with a financial value of $48.7. With the assumption that feed digestibility is increased by 5 percent, the option of improving nutrition through mechanical and chemical feed processing will increase the animal yield by about 6 kg/head-year, valued at $52. The methane emissions reduces by about 10 percent (5 kg/head-year). The option is more expensive than the baseline scenario by about $3/head-year. (Table 5-11)

The incremental cost for the two options discussed above were all positive. For the water management option, the cost of methane emissions reduction is estimated to be $1.01/kg methane reduced. Improving livestock nutrition will cost $0.40/kg methane reduced (Table 5-12).
The NPV of benefit /kg of methane avoided for the water management option is $0.54/kg. That of the improving nutrition option is $0.07/kg methane avoided.

Specify a set of relevant GHGs abatement options and make a separate direct cost and emissions ranking of these compared with reference scenario.
(ii) Analyze and assess the cost of methane emissions reduction and NPV of benefits per kg methane avoided of one or more of the alternatives for GHGs abatement.
Baseline scenario assumes an increase of 19 percent in rice cultiva- tion area and 89 percent in livestock population (Table 5-13), driven by a demand for increased food supply (Table 5-6). There will be no technologies used toward mitigation of GHGs emissions Abatement scenarios were considered by decreasing the GHGs emissions in the year of 2020 by 15 to 20 percent of its value in the reference year. This would be brought about by the adoption of
(i) Water management with the intermittent draining of rice fields during the growing season.
(ii) Improving the nutrition of livestock through mechanical and chemical animal feed processing.
The area under rice cultivation is projected to increase by 19 percent (Institute for Agricultural Planning and Projection, 1996). However, the extent of irrigated area is also expected to increase from 5.46 mha in 1993 to 6.02 mha in 2000, 6.94 mha in 2010, and 7.45 mha in 2020.

A strategy has been developed to reduce methane emissions in year 2020 to reach a level of 9 percent over the base year, 1993. This could be achieved by targeting the two mitigation options as follows.
(i) Carrying out intermittent drainage of 5.5 mha of rice paddy under controllable irrigation. A mitigation of 50 kg CH4/ha-yr will result in a total of mitigation of 273 Gg CH4 through this option.
feed to 4.2 mt/yr will result in a reduction of 5 kg CH4/animal-yr from a total of 4.4 million animals. This will result in a total mitigation of 22 Gg CH4/yr.
(ii) Gradually increasing the quantity of improved (processed) animal
The development objective of the Viet Nam agriculture sector in the next decade will be to ensure food security and export reinforcement. This will be met by the expansion of rice cultivation area and by increasing the animal population together with intensive farming, which will lead to increased methane emissions in the country. The future emissions is estimated by constructing a mitigation scenario of two mitigation options in the agriculture sector.
Table 5-14 shows that the total CH4 emissions of the abatement scenario in agriculture sector with two mitigation options will decrease by 93Gg in 2000, 194Gg in 2010, and 295 Gg in 2020. The total emissions of the abatement scenario will be 361 Gg in 2000, 2,496 Gg in 2010, and 2,743 Gg in 2020.
Total investment cost for the two mitigation options from rice cultivation and livestock will be $1.90 million in 2000, $3.81 in 2010, and $5.71 million in 2020.

On the basis of the agricultural situation in Viet Nam and its development, the scope of the emissions reduction strategy is focused on the rice cultivation and livestock subsectors.
The mitigation options to be promoted are as follows:
Water management leading to intermittent draining of rice fields during the growing season. Improving animal nutrition through mechanical and chemical feed processing.
Furthermore, a list of potential mitigation options has been presented under Section 5.3.1. Whenever adequate data concerning these options become available, these mitigation options could be implemented and considered in developing an abatement strategy.
Short-term (1998 to 2005)
A total of 1.8 mha of rice field will be irrigated and drained during the growing season. Most of this area would be located in the Red River Delta (1.1 million ha) and North Central Coast (0.5 million ha). Nearly 0.4 million head of buffaloes and cattle, and 2.7 million head of swine will be fed by improved methods of animal nutrition through the use of mechanical and chemical feed processing.

Water management and intermittent drainage of irrigated rice paddy fields. Changing the cropping pattern from “two - rice - crop” to “three crops system”. (Rice - Upland crop - Rice). Direct sowing of rice paddy. Using biofertilizer on the crop field. Rational feeding of livestock. Using biogas in rural areas.
The most promising options for reducing emissions are:
(i) Water management and intermittent drainage of irrigated rice paddy fields, and
(ii) Rational feeding of livestock. These options will lead to improve- ments in the standard of living of the rural population.

For the mitigation option in livestock, the required incremental investment is estimated to be $91.9 million. For the mitigation option of water management in rice fields, it is estimated to be $5,620 million until 2020.
(iii) Barriers to adoption of mitigation options are:
Lack of knowledge about methane emissions from rice fields and ruminants on part of government officials, planners, and decision-makers. Limited infrastructure for production and dissemination of technologies. Lack of capital for investment in feed processing facilities and other infrastructure and resource improvements.

he Cost of Emissions Reduction Initiatives (CERI) Curves were developed under the ALGAS Project. CERI curves relate the quantity of T GHGs, which can be reduced or sequestered by mitigation options, to
the cost per unit of GHGs reduction. CERI curves are based on the principle of incremental cost analysis, where
incremental costs are equal to the difference in costs over time between a reference (baseline) scenario and alternative GHGs mitigation scenarios. Based on CERI curves, policy makers, analysts, and other interested groups can understand the impacts of choosing different sets of GHGs mitigation options.
CERI curves for the energy sector were developed with results from the EFOM - ENV model. Seven GHGs individual abatement options and two approaches to CO2 constraint were evaluated using the EFOM - ENV model.
CERI Curve for Individual Options in the Energy Sector
The individual mitigation options were estimated and evaluated for GHGs emissions and costs compared with the business-as-usual (BAU) scenario. The results for the individual abatement options are shown in Table 6-1 and Figure 6- 1.

The COMAP (Comprehensive Mitigation Analysis Process) model was used for assessing several forestry mitigation options. Based on the modeling results, forestry CERI curves were developed for the baseline and feasible scenarios. The forestry mitigation options under the two scenarios consist of five options: Enhanced natural regeneration (F1), Long rotation reforestation (F2), Short rotation reforestation (F3), Forest protection (F4), and Scattered trees (F5). The calculation of the average incremental cost of each option is based on present value of life-cycle cost (endowment cost). The total potential carbon abatement under the baseline scenario is 471 million tonnes, equivalent to 1,727 mt of CO2. The potential carbon abatement of the feasible scenario is 987 mt, or 3,619 mt CO2-equivalent .

Forest protection options under both Baseline and Feasible scenarios have the highest mitigation potential and the lowest cost. The ranked order of forestry options from low to high cost under Feasible scenario is: Forest protection (F4), Enhanced natural regeneration (F1), Planting scattered trees (F5), Long rotation reforestation (F2), and Short rotation reforestation (F3).
Forest protection and enhanced natural regeneration were assessed to be the best options for Forestry and Land-use Change Sector at the National Workshop on GHGs Mitigation Options and other NTE's meetings. They have multiple environment and socioeconomic benefits and can be implemented at the country level in the years to come.
The principal measures for reducing methane emissions from the agricultural sector are water management with the intermittent draining of rice fields during the growing season, and improving nutrition of livestock through mechanical and chemical feed processing.
Methane emissions from rice paddy are projected to decrease from the current 2,111 Gg CH4 per year to 1,838 Gg CH4 by the year 2020 through the intermittent draining of rice fields at the end of tillering and at 15-20 days after flowing.

NATIONAL LEAST-COST GHGs ABATEMENT STRATEGY
Energy Sector
The general GHGs abatement strategy for the energy sector in Viet Nam is to use energy efficiently on both supply and demand sides, minimize the cost of energy, and reduce pollution emissions. The key elements of the strategy are:
Promotion of conservation and efficient use of energy. Promotion of rational use of national energy resources. Utilization of new and renewable energies. Integration of social and environmental concerns in the implementa- tion of a program of sustainable economic development.
Specific elements are as follows:
(i) Power sector loss reduction and efficiency improvement
In the short-term (1998-2005):
The T&D system will be rehabilitated and upgraded. New technology for production of high efficiency transformers will be installed. The standards for medium voltage level will be selected. Improvement of efficiency of existing power plants.
(ii) Renewable energy utilization
In the short-term (1998-2005):
Encourage use of new and renewable energy sources, especially wind power. Establishment of wind farm with capacity of 10-20 MW. Maximal use of hydropower resources with special focus on highly economic projects on Da River, Se San River, and Dong Nai River.
In the medium and long-term (2005 and beyond):
Pursue large-scale utilization of renewable energy resources. Develop other energy sources, such as nuclear power.
(iii) End-use energy efficiency improvement
In the short-term (1998-2005):
Collect and analyze data and conduct feasibility study of standards for electrical appliances. Collect and analyze data and conduct feasibility study for improve- ment of energy efficiency in State-owned industrial enterprises.
VIET NAM
SECTION 6
In the medium-term (2005-2015):
Adopt and implement efficiency standards for electrical appliances. Develop and implement feasible standards for improvement of energy efficiency in existing and new State-owned industrial enterprises and building systems.
Forestry Sector
The GHGs abatement strategy supports the general objectives for the forestry sector which are expressed in the main document on the economic and social development of Viet Nam. The document indicates that the forestry sector should concentrate on: improvements in the economic result of the operations, increasing the rate of forest plantation, accelerating revegetation of bare hills, improving the results of forest exploitation, and creating a forest resource capable of protecting the environment and harboring diverse wildlife.
decade, as follows: There are several concrete objectives for the forestry sector in the next
Strengthen the national protection capability by protecting 9.3 mha of existing forests, increasing the rate of forest plantation, and accelerating revegetation of bare hills. Focus on activities concerning natural forest regeneration and establishment of new plantations in order to reforest 5 mha in the period 1998-2010. By the year 2010, there will be more than 15 mha of forests, with forest coverage at 45 percent of the land area. Provide employment for local people. Gradually improve the living standard for more than 20 million people living in and around forest areas.
With particular reference to the proposed mitigation options, the following strategies are recommended.
(i) Reforestation
Develop feasible reforestation projects in which more productive plantations are established in order to meet the growing demand for wood for industrial use and fuelwood. Reforestation efforts should give more attention to:
Local socioeconomic conditions of the plantation sites and the approach to participation of the local people for planning and implementation of the plantation programs. In fuelwood-deficit areas, in particular, community forestry approach needs to be explored. Consideration should be given to natural reforestation schemes if necessary, combined with natural regeneration, enrichment, or other silvicultural measures. Research should provide locally focused advice on the right species and the best seed resources for reforestation.
VIET NAM
NATIONAL LEAST-COST GHGs ABATEMENT STRATEGY
PAGE 165
SECTION 6
PAGE 166
NATIONAL LEAST-COST GHGs ABATEMENT STRATEGY
Maintenance of plantations, involving replanting where necessary, is an integral part of the reforestation effort, and can determine the success or failure of a program.
(ii) Forest protection
Create nonforest-based livelihood opportunities.
Improve the protection and management of existing forests within the special-use forestland. Implement the policy “Stop logging in natural forests for a given period” to reduce current deforestation rate in the country. Expand the protection forest area from 5.7 mha to about 7 mha.
(iii) Planting scattered trees
Increase the planting of scattered trees to 400 million trees per year. Allocate land to the households for practicing cultivation in forestry- agriculture systems. Expand urban forestry.
(iv) Information and education
Raise public awareness about environment protection, including forest protection and management. Adequate information and education campaign for each mitigation option.
Short-term (1998 to 2005)
The rate of reforestation is planned to reach about 140,000 ha per year, an increase of 30 percent as compared with the average annual reforestation rate in the past 5 years. In addition, about 1.5 billion scattered trees will be planted, and 6.5 mha of existing natural forests will be protected. At the same time, natural regeneration will be allowed in 1.8 mha of degraded forests. As a result, there will be about 1 mha planted in forest by 2005.
Medium-term (2005 to 2015)
In order to maintain and improve the carbon sinks in the country, forest protection options will continue to be carried out. The average annual reforestation rate will be reduced gradually. From 2005, about 100,000 ha of forest and 200 million scattered trees will be planted annually. It is estimated that by 2015, more than 2 million additional ha would have been planted since 1998, including 1.2 mha of protection forests.
Long-term (beyond 2015)
Reforestation will continue at a rate of 160,000 ha per year. About 1 mha of wasteland will be revegetated by 2020. Natural forests will be also protected for the whole period. By the year 2020, a number of forest products such as roundwood, timber, etc. from established plantations and some natural forests

The development strategy of Viet Nam agriculture in the next decade is stated as follows:
“Continuing to firmly assure the foods and foodstuffs matters for the full society and export reinforcement. Strongly developing all high valuable tree kinds via the intensive cultivation in order to respond to the requirement of raw materials for processing industry. Forming the regions of concentrated breeding, the firms of processing foodstuffs with several shape/scale types. Strongly developing the processing industry, performing the investment in depth, closely attaching the process of renewed processing equipment to the rearrangement of system of agricultural-forest all-products processing firms.’’
The following discussion presents a number of tasks to be undertaken to

(iii) To effectively increase the export volume of agricultural products.
Intensify cultivation of food crops, concentrating on productivity of rice and corn. Rapidly produce new seeds, especially hybrid seeds, and strains with high efficiency, quality, and good resistance to pests and diseases. Invest in the rice industry, including the drying system, grinding, polishing, classification of rice via the modern equipment, and port facilities. To establish a policy of support for the food produc- ers, ensuring reliable and competitive income for the long term. The objective is to increase food productivity from the current 26 mt per year to between 30 and 32 mt in year 2000.
Breeding of livestock:
(i) Enhance the program of producing the improved strains. To assure breeds are developed according to the most recent research in the field. To rapidly develop the industry for processing the feeds in the larger breeding region.
(ii) Implement the big herd-developing program to produce high quality, lean meat through the method of advanced hybridiza- tion for prompt enhancement of product volume.
Implementation of breed improvement will allow achievement of the year 2000 target of 7 million buffaloes and cows, 17 million pigs, and 170 million poultry, and the program will enhance the livestock productivity to meet the targets of chopped meat of 2 mt per year of all kinds, and 60,000 t of fresh milk, in the year 2000. This program is expected to relate closely with the improvement of animal nutrition through mechanical and chemical feed processing.
The abatement strategy for the agriculture sector consists of two measures:
(i) Reducing methane emissions from rice paddy while maintaining or increasing the rice production.
In Viet Nam, rice plays a key role in culture and diet. The GHGs abatement strategy must satisfy the following criteria: improvement of rice productivity, low requirement of hard currency, and ecological stability.

SECTION 7
Background
Boilers in the Viet Namese industrial sector have operated for a long time. Consumption of thermal energy can be 150 percent of that used in comparable industries in OECD countries. Measures for improvement of boiler efficiency in Viet Nam will save a large amount of fuel and reduce air pollutant emissions.
There are about 600 boilers operating at present in the industrial sector of Viet Nam, with capacity ranging from 4 to 230 tonnes per hour, but most of them have a capacity of less than 10 tons per hour. There are only about 100 boilers with capacity from 10 to 230 tonnes per hour. They are operating in the thermal power industry, sugar industry, and paper industry. The efficiencies of the boilers range from 35 to 70 percent. Good practice efficiency may reach 85 percent. Therefore, the opportunity for energy saving by improving boiler efficiency is large.

SECTION 7
Introduction
Although the Viet Nam Government has made strong efforts in reducing forest loss in the country, the average annual deforestation rate is still more than 100,000 ha. Main factors that have caused the forest loss in Viet Nam are connected with the country's recent history. Due to rapidly increasing population, the people have reclaimed not only most of the deltas and coastal plains for farming, but a great deal of forest land has become inhabited, mainly by ethnic minorities. The land squatters prefer dense forest lands for food production by slash and burn practices, which has been seen as a major cause of deforestation. In addition, during the war, a large forest area including conservation forests was destroyed. In addition, natural forest has to be cleared for wood to meet the increasing demands in the country.
There are about 3 mha of brush lands needing immediate reforestation. Plantation establishment is one of the best solutions for releasing pressure on natural forest to meet wood demand and for assisting in rehabilitation of the ecological environment.
The proposed short-rotation-reforestation project is planned for implementation in Lang Son and Ha Bac provinces, and is aimed at the following goals:
Conserving and expanding carbon sink by reducing the pressure on the natural forest. Strengthening reforestation and forest land protection in the area. Providing employment for 10,000 households living in mountainous areas. Protecting up-river forests and preventing soil erosion. Decreasing shifting cultivation of ethnic minorities in the area.
Project Objectives:
The project intends to reforest 12,500 ha in Lang Son and Ha Bac provinces during 4 years. The project objectives are:
(i) Conserve up-river forest and enhance carbon sink of degraded forest land.
(ii) Establish 12,500 ha of Pinus massoniana and other tree species. (iii) Create employment opportunities for at least 10,000 local households
living in mountainous areas. Engage them in reforestation and forestry business.
(iv) Conserve soil and water and enhance biological diversity.
Project Activities:
(i) Set up a plan of land-use at commune level. (ii) Allocate forest land to the participating households. (iii) Train project staff and disseminate information for local people. (iv) Provide saplings and other relevant materials for the households (v) Establish credit support and financing in planting, maintaining, and
(vi) Establish a durable market for wood production. protecting forests.

SECTION 7
Background
Viet Nam is an agricultural country, with 80 percent of its population living in the countryside, carrying out the cultivation of more than 7.4 mha of agricultural land. Of this cultivated land, 4.3 mha are rice fields, and more than 1.2 mha are used for cultivation of long-term plants. Rice cultivation areas are usually located in the river deltas, and the most important are the Red River Delta and the Mekong River Delta.
Rice cultivation has the most significant contribution to the emissions of GHGs from the agriculture sector. The total CH4 emissions from rice paddies is estimated at 1,755 Gg CH4 in 1993 (68 percent of total CH4 emissions in the country, and 78 percent of total CH4 emissions from the agricultural sector). Methane emissions from rice cultivation is expected to grow to 1,893 Gg CH4 in 2000, 1,998 Gg CH4 in 2010, and 2,111 Gg CH4 in 2020.
The mitigation area identified in this project is the Red River Delta, in which the cultivation is under the intensive farming system. The Government and farmers in this area have invested in the irrigation system for a long time.
Methane emissions and abatement studies are expected to be conducted for estimating the possible contribution of water management in rice paddies to methane emissions reduction.
Project Objectives:
Global Environment Obiective:
Reduction of methane emissions from rice paddies while maintain- ing the rice productivity.
National Development Obiectives:
Increase rice production in response to the increasing national consumption requirements and the demand for exports, with the indirect effect of improving the life of the local people. Conduct a demonstration project to determine whether the recom- mended practices are cost-effective for farmers. Transfer the practices to agricultural managers and farmers.
Project Activities:
(i) Conduct experimental trials for water management in rice paddies in three plots (Hai Duong, Thai Binh, and Ha Tay) in the Red River Delta.
(ii) Develop the applicable study. (iii) Exchange information through training seminar or workshop. (iv) Transfer the practices to major rice producing areas of the country. (v) Monitoring and evaluation.
The Institute of Meteorology and Hydrology (IMH) shall implement the project for Agricultural Planning and Projection with the active participation of Agrometeorological Experimental Stations and Region Centers for Agriculture.

Projects prepared and implemented should be tailored to the local conditions in the area where they are to be implemented. In order to serve the projects and the general development in the area, economic, technical, and service units should be established in the area, and a suitable social and technical infrastructure should be created.
The document specifically indicates that the forestry sector should concentrate on: improvements in the economic results of the operations, increasing the rate of forest plantation, acceleration of revegetation of bare hills, improving the results of forest exploitation, and creating a forest resource
In general, several concrete objectives for the forestry sector in the capable of protecting the environment and harboring diverse wildlife.
next decade are as follows:
(i) Protect 9.3 mha of existing forests, increasing the rate of forest plantation, and accelerating revegetation of bare hills.
(ii) Focus on activities concerning natural forest regeneration and establishment of new plantations in order to reforest 5 mha in the period 1997-2010. By the year 2010, there will be more than 15 mha of forests, and forest coverage will have increased to 45 percent of the total land area.
(iii) Provide employment for local people and gradually improve the living standard for more than 20 million people living in and around forest areas.
In addition, the sector should apply relevant research to improving cultivation systems for sloping land. Close links between forestry and agriculture should be created, and also between forest operations and forest industries. The management of State forest enterprises should be reformed, and all other economic sectors should be encouraged to take part in forest operations.

Agriculture Sector:
Viet Nam’s agriculture sector has undergone various changes owing to the evolution of the political and economic environment. The Doi Moi policy and the subsequent renovation process were aimed at transforming the economic system from a planned to a market-oriented economy. The economic incentives farmers gained through the renovation process have enhanced agricultural production. In fact, during the last five years, the GDP in the agriculture sector achieved an average annual growth of 4-5 percent.
The goals of the agricultural sector are to:
(i) satisfy the food requirement for the people’s consumption in any situation, to sufficiently ensure the food source and enough raw material for the industry, and to further increase the export volume;
(ii) develop all highly valuable tree varieties via intensive cultivation, and establish new plantations in order to respond to the require- ment of raw materials for the processing industry; and
(iii) form regions of concentrated breeding of crops, and support the firms that process foodstuffs.
The following programs support these goals:
(i) Intensifying cultivation of the food crops (ii) Diversification of agriculture.
The program of intensifying cultivation of food crops sets a target of increasing grains production to 35 mt in 2010 and 45 mt in 2020.
The environmental objective of the agriculture sector is to ensure the food requirements of the country by adopting strategies and technologies

that are most appropriate, cost-efficient, and environment-friendly. However, GHGs reduction has not been included in these strategies. Methane emissions reduction from rice fields is a main mitigation measure proposed for the agriculture sector of Viet Nam. Methane reduction will be implemented by controlling the water irrigation and drainage of rice fields, with intermittent draining of rice fields during the end of tillering and at 15- 20 days after flowering. This proposed project might reduce methane emissions from rice paddies by 30-50 percent.

The National GHGs Abatement Plan for Agriculture will focus only on
In setting up the National Plan for Environment and Sustainable Development, Viet Nam has recognized its environmental problems. The goals and specific objectives of the plan are summarized below and in Table 8-3.
The goals:
(i) To satisfy the basic material, spiritual, and cultural needs of all the people of Viet Nam, both present and future generations, through the wise management of national resources.
(ii) To define and establish policies, action plans, and institutional structures to ensure that the sustainability of national resources use will be fully integrated into all aspects of Viet Nam’s social and economic development process.
The specific objectives:
(i) Maintain Viet Nam’s wealth of genetic diversity of both domesti- cated and wild species for current and potential benefit.
(ii) Ensure the sustainable use of Viet Nam’s natural resources by managing intensity and pattern of use.
(iii) Maintain overall environmental quality necessary for the well- being of human existence.
(iv) Achieve a population level and distribution that is in balance with natural sustainable productivity at a dignified standard of living.
A specific objective for GHGs emissions reduction has not been formulated in this National Plan. Understanding the issue, Viet Nam is completing the Country Program for Implementation of UNFCCC as a part of the National Plan.
The national and sectoral objectives of the Country Program for Implementation of UNFCCC on GHGs emissions reduction in Viet Nam are based on national development goals, taking into account national and regional interests in economy and environment. It should also achieve global benefit. The National Plan does not conflict with those of other sectoral, national, regional, and global programs, but serves to reinforce them, and forms a part of a broad coordinated program for sustainable development. It will be a part of the commitment of Viet Nam to UNFCCC and the country’s environmental policy, contributing to the global efforts to protect our climate (see Table 8-4).

SECTION 8
The Ministry of Agriculture and Rural Development has full responsibility for forestry sector administration and management and is also in charge of forest production and other related activities. There is a need to establish a strong institutional mechanism for effectively undertaking GHGs abatement related activities.
In order to implement the identified forestry mitigation options successfully, there is a need to create close links between forestry and agriculture and between forest operations and forest industries. Participation of other economic sectors and local communities is also important in the success of plans and programs implemented in the sector, including forest protection, reforestation, and other related activities. History provides ample evidence that projects planned and executed with little regard for the welfare and aspirations of local people cannot succeed. Thus, all activities in the forestry sector will have to be planned and executed in close cooperation with the local people.
At present, the Department of Forestry and several institutions under the Ministry of Agriculture and Rural Development (MARD) conduct the implementation of forest protection and reforestation. The Ministry needs to establish a unit of protection and management for the protection and special-use forests. In particular, a Steering Board including members of the Viet Nam Climate Change Country Team (VNCCCT) needs to be established soon, and shall be responsible for activities pertaining to GHGs inventory, GHGs mitigation assessment, and GHGs abatement strategies.
The Government will support more funding for operations such as forest protection, watershed management, biodiversity conservation, reforestation, the development of special-use forests (nature reserves and national parks), and settlement of shifting cultivation.

AND FUTURE ACTIONS
iet Nam signed the United Nations Framework Convention on Climate Change (UNFCCC) at the United Nations Conference on Environment and Development in Rio de Janeiro, Brazil, in June 1992, and ratified
this Convention on 16th November 1994. Since February 1995 Viet Nam has been a Party to the Convention. Viet Nam is a Non-Annex I country to the Convention but the Government of Viet Nam has tried its best to optimize its organizing capacity to undertake relevant steps for the implementation of UNFCCC measures in order to contribute to humankind responses to climate change.
One of the activities for climate change in Viet Nam is implementation of the “Asia Least-cost Greenhouse Gas Abatement Strategies (ALGAS) Project”, funded by GEF with the ADB as the executing agency. The project has been implemented in 12 Asian developing countries including Viet Nam.
The main tasks of the Project were:
(i) Develop a National Inventory of GHGs Sources and Sinks (ii) Identify Options for Mitigation Abatement of GHGs (iii) Develop a Least-Cost Strategy for Mitigation/ Abatement of GHGs.
Fulfilling these tasks under the ALGAS Project, the1993 Viet Nam National GHGs Inventory, GHGs mitigation option assessment, and National GHGs Mitigation Abatement Strategy have been developed. This strategy should be adopted by the Government and implemented on a national basis.
Implementation of the GHGs Abatement Strategy should be integrated into aspects of the country’s development and should meet the following national and international objectives.
National objectives:
In setting up the National Plan for Environment and Sustainable Development, Viet Nam has recognized its environmental problems. The goals and specific objectives of the plan are described below.
Goals:
(i) To satisfy the basic material, spiritual, and cultural needs of all the people of Viet Nam, both present and future generations, through the wise management of national resources; and
(ii) To define and establish policies, action plans, and institutional struc- tures to ensure that the sustainability of national resources use will be fully integrated into all aspects of the country’s social and economic development process.
Specific Objectives:
(i) Maintain Vietnam’s wealth of genetic diversity of both domesticated and wild species of animals, for current and potential benefit.
(ii) Ensure the sustainable use of Vietnam’s natural resources by managing intensity and pattern of use.

Specific objectives of the strategy for GHGs emissions reduction, which have been formulated in the ALGAS Project, will be as stated below, and as a part of the National Environmental Plan.
International objectives:
The national and sectoral objectives of the strategy on GHGs emissions reduction in Viet Nam are based on national development taking into account national and regional interests in the economy and environment. It should also achieve global benefit. The development strategy does not conflict with those of other sectoral, national, regional, and global plans, but serves to reinforce them, and forms a part of a broad coordinated program for sustainable development. The National GHGs Abatement Strategy in this study will facilitate development of the country program for effective implementation of Vietnam’s commitments as a developing country under the UNFCCC.
National Implementation Strategy
In order to implement fully the GHGs strategy and at the same time undertake commitments as a party to the Convention, and to optimize and use all financial assistance and technology transfer, Viet Nam has developed a Country Program comprised of four main policies:
(i) Reducing anthropogenic emissions by sources and enhancing sinks of all GHGs by using cleaner energies, reducing energy loss, saving energy, and planting and protecting forests;
(ii) Adapting to climate change to foster agriculture’s adaptability, to manage the use of water sources, to prevent floods, and to monitor the prevention of the natural calamities;
gate and to enforce relevant Government Decrees on responding to climate change; and
(iii) Formulating policies on compiling and implementing laws to promul-
(iv) Formulating policies on expanding international cooperation.
The Country Program will be approved by the Government and guide the implementation of the National GHGs Abatement Strategy and commitments.
In the context of the National Strategy and implementation program, the Sectoral GHGs Abatement Strategies described below will be implemented.
Energy
The GHGs abatement strategy in the energy sector supports the national energy development policy. In general, this strategy may be summarized as:
(i) To maintain rapid growth and efficient and sustainable economic development by satisfying the energy demand for long-term develop-

and demand sides; (ii) Promotion of conservation and efficient use of energy on both supply
(iii) Promotion of rational use of national energy resources; (iv) Utilization of less GHGs emitting sources and new and renewable
energy; and (v) Integration of social and environmental concerns in the implementa-
tion of program of energy sector development and economically sustainable development.
This strategy will be implemented through energy programs and measures:
(i) Implementation of demand-side management (DSM) program of improving efficiency, reducing the intensity of energy consumption per unit of product, and electricity load management, including:
Compact fluorescent lamps; Energy-efficient refrigerators; Energy-efficient air conditioners; and Highly efficient electric motors.
Efficiency improvement in coal cooking;
(ii) Fuel substitution to less GHGs-emitting energy sources:
Fuel switching in existing thermal power plants from coal to gas; and Switching from cooking with coal to biomass and natural gas.
(iii) Identify and diversify energy sources, with special attention given to the most important and clean energy sources:
Wind power; Nuclear power; and

For the energy sector, the implementation of mitigation options can be supported by energy institutions such as State oil and gas companies, the Viet Nam electricity company, the industry sector, commercial banks, including ADB and World Bank. The GEF and funding sources from other international, financial, and technical organizations may be involved. Individual countries will be also requested for financial assistance for implementing the abatement initiatives in the energy sector.
For the forestry sector, the implementation of several mitigation options can engage financial institutions like the Vietnamese Reforestation and Forest Protection Fund, and receive credits from State Bank and Bank for Agriculture and Rural Development, State plantation enterprises, Agro-forestry Department, and, for relevant programs or projects, from World Bank, ADB, or GEF. Credits from non-refundable aids, foreign investment, and people’s capitals can also be mobilized to implement the mitigation options.
For the agriculture sector, the implementation of mitigation options can be financed from the State budget through the Ministry of Agriculture and Rural Development, from local Government through the Department of Agriculture and Rural Development of Provinces, and from Agricultural Agency, the farmers, and NGOs. Credits from the Bank of Agriculture and Rural Development are also provided to the agriculture sector. However, mitigation options that relate to capacity building and technical assistance can engage GEF, World Bank, ADB, international organizations, and donor governments.
