There is a need to assess the potential impacts of climate change on agriculture in order to plan appropriate adaptation measures. Farmers are already adapting to these changes to a certain degree. This article presents a case study of rainfed and farmer-managed irrigated agriculture in the Indrawati Basin, Nepal. It describes farmers' perceptions of climate change, an analysis of historical water availability, and future projections of temperature and precipitation. Adaptation strategies already being used by farmers are identified and new ones are recommended based on primary information collected from farmers and an in-depth analysis of the climate data.
