Impact of Climate Change on Agriculture
Introduction
Climate change is one of the biggest and urgent issues of the present world and overwhelming scientific consensus is concerned with climate change. The earth’s climate is rapidly changing mainly as a result of increase in greenhouse gases caused by human activities. Over the last 100 years (1906-2005), global temperature has increased by 0.74°C and it is expected to increase by about 0.2°C per decade over the next two decade (IPCC 2007). For developing countries like Nepal, it is not just an environmental phenomenon but also an economic, social and political issue. Nepal is among the most vulnerable countries on earth with regard to climate change however, emission of green house gas

Such a study would contribute towards a better understanding of the intensity and impacts of global changes. The first step in such a study would be to understand existing farming practice in Far-Western of Nepal. Studies on perceptions, local knowledge, and adaptive strategies at the household and community levels, as well as lessons learned, can provide the basis for concepts and methods of assessing climate change impacts, vulnerability, and adaptation on livelihood of the local people.

Many climate researchers have confined their studies to the biological and physical domains, concentrating mainly on representing the response of crops to various changes in climate. However, studies focusing on the socio economic aspects of global climate change are sparse and have almost exclusively restricted their analysis to the impact of environment modifications on agricultural production (Vedwan & Rhoades 2001). Micro-level studies of the impact of climatic variability on farming system and adaptive strategies as well as their consequent response under climatic uncertainty are relatively few at regional level. This is, therefore, a study of climatic uncertainty and its impact on agriculture especially farming system, in Far-Western part of Nepal. Farmers and rural communities in Nepal and around the world are already adapting to climate change and developing new practices to meet changing circumstances (Bordoni 2009). This research will mainly
