Nepal, a Least Developed Country, is considered to be one of the countries most vulnerable to climate change impacts due to various factors such as its rugged mountain topography, acute poverty, especially in rural areas, and weak national and local institutional capacity. Many communities in Nepal, particularly those inhabiting mid-hill and high mountains, already live in very poor conditions. Even a small change in climatic conditions adversely affects their lives and livelihoods.Governments and communities are facing various constraints in managing the observed and anticipated impacts of climate change. One of the challenges to adaptation planning in the context of Nepal is to understand the complexity and uncertainty arising from the inherent dynamic nature of the climatic, ecological, socio-economic and political systems (Thapa et al, 2010). Continuous efforts havebeen made to tackle this challenge at national and international scales. For example,there has been a focus on building a sound scientific knowledge base for makingclimate projections and drawing vulnerability assessment methods.
