Concepts of Climate Change Impacts and Vulnerability

Vulnerability – the propensity or predisposition to be adversely affected. It encompasses a variety of concepts and elements including sensitivity or susceptibility to harm and lack of capacity to cope and adopt.

Exposure - the presence of people, livelihoods, species or ecosystems, environ- mental functions, services, and resources, infrastructure, or economic, social, or cultural assets in places and settings that could be adversely affected

Hazard - potential occurrence of a natural or human-induced physical event or trend or physical impact So

Concepts of Climate Change Impacts and Vulnerability

Adaptation – the process of adjustment to actual or expected climateand its effects. In human systems, adaptation seeks to moderate or avoid harm or exploit beneficial opportunities. In some natural systems, human inter- vention may facilitate adjustment to expected climate and its effects

Risk - potential for consequences where something of value is at stake and where the outcome is uncertain, recognizing the diversity of values

Impacts – effects to natural and human systems of extreme weather and climate events and of climate change. Impacts generally refer to effects on lives, livelihoods, health, ecosystems, economies, societies, cultures, services and infrastructure due to the interaction of climate changes or hazardous climate events occurring within a specific time period and the vulnerability of an exposed society or system.

Step 1. Scoping and Designing Adaptation Project

Asia-Pacific Network for Global Change Research  

torrential rains, typhoons, storm surge, dry spells, rain‐induced  landslides, coral reef bleaching and rat infestation in farmlands. These gave the participants ideas on the focus of the vulnerability and adaptation assessments that they could implement in their areas. 

 Meanwhile,  hands‐on  training  on  the  use  of customized  SimCLIM  for  Albay,  called AlbayCLIM,  was  led  by  Drs.  Peter  Urich  and Peter  Kouwenhoven  from  CLIMsystems,  Ltd. Participants  generated  climate  change  and sea‐level  rise  scenarios  using  various  Global Circulation  Models  (GCMs),  as  well  as conducted extreme events analysis and water tank modeling. Results of the climate and sea‐level rise modeling were deemed highly useful in  the  revision  of  the  Comprehensive  Land Use  Plan  (CLUP)  that  the  province  was undertaking.  

  2.4  Actual impacts, vulnerability and adaptation assessment  Following the concepts  learned  in the training, two case study sites were chosen where the actual vulnerability and adaptation assessments were conducted  from May to October 2011. These were the municipalities of Bacacay and Oas, which represent two of the three major landscapes in Albay, namely,  coastal  area  and  hilly,  mountainous  terrains,  respectively.  The  focus  on  coastal  and forest/upland  communities  for  the  actual  assessment  was  due  to  the  fact  that  these  areas  are among the most vulnerable ecosystems to climate change. These are where the so‐called ‘poorest of the poor’ could also be found.  The Adaptation Policy Framework (APF) was used as a guide in conducting the assessment. This is a second‐generation  framework  with  more  holistic  approach  towards  impacts  assessment  and  the ultimate goal of  informing adaptation policy (UNDP/GEF 2004). Central to this  is the assessment of current  vulnerability,  particularly  from  climate  variability  and  extremes,  placing  emphasis  on understanding current climate risks before moving to the  ‘uncertain territories of what  lies ahead’ (Dessai  et  al.  2005).  The  APF  has  five  major  components  (boxes)  linked  by  two  cross‐cutting components (adaptive capacity and stakeholder context) (Figure 1).  Based on the steps outlined in the APF, the following were the methods used in conducting impacts, vulnerability and adaptation, assessment of the coastal and upland communities:  Step  1.  Scoping  and  designing  an adaptation  project.  This  entailed scoping  the  project,  defining  the objectives,  establishing  project team,  reviewing  literature, choosing appropriate methods, etc. Much of  these were accomplished during  the  preparation  of  the proposal, the project’s initial meeting and the succeeding collection of secondary data.

Approaches for Impacts and Vulnerability Assessment

(Natural) hazards-based approach – analyze possible outcomes from a specific typhoon hazard

Vulnerability-based approach – determine the likelihood that current vulnerability may be affected by future climate hazards

Adaptive-capacity approach – analyze the barriers to adaptation and propose how they can be overcome

Policy-based approach – investigate the efficacy of an existing or proposed policy in light of changing exposure or vulnerability

Step 2. Assess Current Vulnerability

Resources, approaches, methods and tools would vary depending on the nature of output desired and the scale

Some impacts and vulnerability assessment methods:GIS-based vulnerability mapping

Sustainable Livelihood Framework

Multi-criteria Vulnerability Index

Use of indicators following the vulnerability components or DPSIR Framework

Participatory approaches (usually for local level)

exposure (left) the south to north gradient of temperature and precipitation (total and interannual

variation) is clearly evident. Sensitivity is more varied, showing pockets of high sensitivity in the northern

and northwestern areas of the country and in southeastern Mali (owing in part to high infant mortality

rates) and less sensitivity around Bamako (the capital) and in the west and the east. Adaptive capacity

declines with distance from Bamako and other urban centers, as well as from the Niger River. For the

PCs (bottom row), PC1 largely comprises climate indicators and those that are strongly influenced by climate, such as malaria and soil organic carbon, so it looks quite similar to the exposure component on

the row above. PC2 combines (in the order of their loadings) maternal education, household wealth,

health infrastructure, and the poverty index; hence it can be straightforwardly interpreted as a measure

of household social vulnerability. PC3 includes two indicators with positive loadings, child stunting and household wealth; and two with negative loadings, the decadal component of precipitation and malaria

stability. This component overwhelmingly is driven by child stunting and hence could be seen as a stand-

in for child wellbeing and malnutrition. Overall, the two approaches bring out different information that

is complementary and may help to understand spatial patterns of vulnerability that can be useful for

targeting interventions.

In summary, comparing spatial index approaches to PCA, the PCA appears to be a useful exploratory

tool as it permits the developer to uncover spatial relationships between different components of vulnerability and to avoid biasing the results of a purely additive approach by the use of too many

components that share the same spatial patterns. It can also provide additional insight into the

vulnerability patterns and components. However, individual PCs, especially of higher order, are often

not easy to interpret. Moreover, Midgley (personal communication) argues in favor of the additive approach on a conceptual basis, in the sense that each indicator may contribute separately to overall

vulnerability. For example, while child malnutrition and poverty levels may co-vary across space, and

hence be collapsed into one PC, that does not mean that they don’t contribute separately to the ability

of people to cope with stressors.

drought. The city’s lessons from past typhoons and flooding events have improved their risk reduction responses,

as seen in the foregoing measures that it has been pursuing. The maturing capacity for disaster risk response best

explains this score.

Drought and sea level rise, on the other hand, are remote events to the city, and are not perceived to be as

pressing as floods or typhoons. This explains the minimal actions and investments on these hazards.

By sector, infrastructure posted the highest level of adaptive capacity as seen in the focus on structural solutions

for water-related hazards. The social sector has the lowest level of adaptive capacity, owing to the short-term and

disaster-response paradigm adopted for its services. Further, its capacity heavily relies on the performance of

other sectors, which generally scored low to medium in many of the hazards identified.

Summary of Vulnerability by Sector and Climate-Related Hazard

Combining the scores from the

threat level and adaptive

capacity, the relative vulnerability

of the city of Iloilo by hazard is

6.42 out of 10. This can be traced

to the apparent concentration of

present efforts on disaster

response to flooding and

typhoons and less attention on

the other hazards, as informed by

experience. While the threat level

for these two hazards is the

highest, the strengthening of

response efforts does offset the threat to a certain level.

Of the hazards identified, given the minimal efforts to address its impacts, the city appears to be most vulnerable

to drought. While the threat level is low on this hazard, adaptive capacity was also low.

Of the five sectors, land use and

environment are the most

vulnerable to multi-hazards. Both

sectors posted the highest threat

level considering the magnitude

and nature of resources affected

and the inadequate actions to

address them beyond “business

as usual”. The economic sector

appears to be the least vulnerable

to hazards, mainly because this

sector is market driven and

private-sector led. This suggests a

higher autonomous capacity of actors in coping and recovering from temporary shocks and stresses.

By sector, infrastructure posted the highest level of adaptive capacity as seen in the focus on structural solutions

for water-related hazards. The social sector has the lowest level of adaptive capacity, owing to the short-term and

disaster-response paradigm adopted for its services. Further, its capacity heavily relies on the performance of

other sectors, which generally scored low to medium in many of the hazards identified.

Summary of Vulnerability by Sector and Climate-Related Hazard

Combining the scores from the

threat level and adaptive

capacity, the relative vulnerability

of the city of Iloilo by hazard is

6.42 out of 10. This can be traced

to the apparent concentration of

present efforts on disaster

response to flooding and

typhoons and less attention on

the other hazards, as informed by

experience. While the threat level

for these two hazards is the

highest, the strengthening of

response efforts does offset the threat to a certain level.

Of the hazards identified, given the minimal efforts to address its impacts, the city appears to be most vulnerable

to drought. While the threat level is low on this hazard, adaptive capacity was also low.

Of the five sectors, land use and

environment are the most

vulnerable to multi-hazards. Both

sectors posted the highest threat

level considering the magnitude

and nature of resources affected

and the inadequate actions to

address them beyond “business

as usual”. The economic sector

appears to be the least vulnerable

to hazards, mainly because this

sector is market driven and

private-sector led. This suggests a

higher autonomous capacity of actors in coping and recovering from temporary shocks and stresses.

Step 4. Formulating an Adaptation Strategy

Creation of a set of adaptation policy options and measures in response to current climate vulnerability and future climate risks

Selection of methods, tools and processes should be tailored to specific planning context

Use of community-based approaches for local level needs

Involves trade-off analysis for prioritization: valuation methods, cost-benefit analysis, benefit-cost ratio, cost-effective analysis, multi-criteria analysis

Characteristics of successful appraisal: practical, relevant, robust and comprehensive

Step 5. Continuing the Adaptation Process

Albay challenged the provincial government particularly the Provincial Agricultural Services to

be more aggressive in addressing the needs of one of the poorest of the poor groups in our

society – the farmers and fisher folks.

(d) Barangay Level Composting aims to reduce

the volume of garbage dumped at the land fill

and process the compost into organic fertilizer

thus reducing methane emissions from

agricultural lands.

(e) Palanog Cement Factory (Business Sector) is

practicing the substitution of fossil fuels by rice hull to reduce greenhouse gas emissions.

(4) Institutional Initiatives

A) APSEMO- Disaster Management/Disaster Risk Reduction

B) CIRCA -Climate Risk Reduction and Climate Change Adaptation

The provincial government of Albay established the Center for Initiatives and Research on

Climate Adaptation (CIRCA) in 2008, a living research and training institution in collaboration

with the Environment Management Bureau (EMB), World Agroforestry Centre (ICRAF), Bicol

University (BU) and the University of the Philippines Los Banos (UPLB). Its goal is to

strengthen capacity for research and project and program implementation in sustainable

agriculture, forestry, fisheries, energy and eco-cultural tourism in the light of climate change.

Take Home Message

Impacts and Vulnerability Assessment is an important and critical step in adaptation planning

Selection of methods and tools depends on the purpose, scale and context of the study

Combination of different approaches, i.e., top-down and bottom-up; quantitative or qualitative, make the assessment more robust

The resulting assessment may still reflect a lot of uncertainties but this is not a hindrance for effective adaptation planning
