Study was conducted in least vulnerable districts (LVD) and highly vulnerable districts (HVD) of Karnataka. The results reveal that, in the LVD most of the farmers perceived that lower productivity and profitability of crops as the most visible impact of the climate change which has been ranked 1st (75.33 score) and incidence of farmers suicide with a score of 9.82 being ranked last. In case of HVD, farmers perceived increasing rural-out migration (78.98) as a most threatening impact of climate change hence it is placed at 1st rank and increasing price of food items with garette score of 27.12 placed at last rank. In both HVD and LVD, most of the farmers chosed drip irrigation, availing crop insurance scheme and construction of farm pond as the first line of defence to mitigate effects of climate change. However, the mitigation measures adopted by farmers to overcome the problem of groundwater depletion and climate change was found to be higher in HVD as against LVD.
