Abstract

There is ample evidence to suggest that Sri Lanka’s climate has already changed. However, the bigger question of national importance is what Sri Lanka’s climate will look like in 50 or 100 years and how prepared the country is to face such changes. This report reviews the status of climate change (CC) research/activities in Sri Lanka in terms of observed and projected climatic changes, their impacts on water resources and agriculture, CC mitigation and adaptation, and research needs. The study also developed a pilot level CC Vulnerability Index, which was subsequently mapped at district level. The maps indicate that typical farming districts such as Nuwara Eliya, Badulla, Moneragala, Ratnapura and Anuradhapura are the most vulnerable to CC due to their heavy reliance on primary agriculture.
