    EXECUTIVE SUMMARY

    The National Communication comprises, the National Circumstances; Greenhouse Gas Inventory;Impacts and Vulnerability; Mitigation Options and Adaptation Responses; Policies and Measures;Education, Training and Awareness Programmes; Constraints and Technological Needs andRecommended Research Studies and a Portfolio of Projects.

    National CircumstancesSri Lanka with an areal extent of about 65,610 square kilometres lies between 6o and 10on latitude andbetween 80o and 82oe longitude. The island consists of a mountainous area in the south-central parts anda vast coastal plain, which surrounds it. Despite the relatively small size of the country, there isconsiderable variation in climate over time and space. The annual average rainfall varies from below1000mm (39) over a small region in the arid parts of the north-west and south-east of the island to over5000mm (197) in a few places on the south-western slopes of the central hills. There is little seasonalvariation of temperature. The mean annual temperature in the coastal areas below 150m in elevationranges from 26.0oc to 28.0oc while in the hill country above 1500m, it ranges from 15.0o c to 19.0o c.

    Sri Lankas population which at the last census taken in 1981 was 14.8 million, is projected to reach 19.0million by the year 2001 and 23.1 million by the year 2031. The population is unevenly distributed acrossthe country. Nearly 60.0% is concentrated in the wet zone, which includes both the maritime provinceswith higher levels of economic development and the areas given over to the cultivation of plantationcrops. Over 75% of the countrys population live in rural areas.

    Until the 1960s, the Sri Lankas economy depended heavily on the export-oriented plantation crops oftea, rubber and coconut. By 1998 the major sector of the growing economy was the services sectorcontributing 53.0% to the Gross Domestic Product (GDP). This was followed by the agriculture,fisheries and the forestry sector with 21.3% and the manufacturing sector with 16.5%. The three majoreconomic activities in the country are agriculture and livestock, manufacturing and fishing. Together theycontribute 37.0% towards the Gross National Product and provide employment to 53.0% of the totalemployed. The agricultural sector comprises two sub-sectors, one producing mainly for the domesticmarket and the other mainly for the export market. Paddy is the main crop within the domestic sector.The export sector is dominated by tea, rubber and coconut. A variety of animals are raised in the countryincluding neat cattle, buffaloes, sheep, goats, pigs and poultry. The dairy and the poultry industriesrepresent the more prominent and organized sectors of the countrys livestock industry. Fish productionwhich includes both marine fish production (coastal, offshore and deep sea) and aqua culture fishproduction (inland, coastal brackish water prawns and cultured prawns), contributes on the average 3.0%to the Gross National Product. The manufacturing sector consists of three sub-sectors, i.e. factoryindustry, processing of plantation crops and small industries. Together they contributed 17.1% of theG.N.P. in 1998. Factory industry is the most important of the three sub-sectors accounting for 78.0% ofthe value added in the manufa...
