Impact of Climate Change on Rainfed Agriculture in India: A Case Study of Dharwad
Asha latha K. V., Munisamy Gopinath, and A. R. S. Bhat developing countries, climate change will cuase yield declines for the most important crops and South Asia will be particularly hard hit (IFPRI, 2009). Many studies in the past have shown that India is likely to witness one of the highest agricultural productivity losses in the world in accordance with the climate change pattern observed and scenarios projected. Climate change projections made up to 2100 for India indicate an overall increase in temperature by 2-40 c with no substantial change in precipitation quantity (Kavikumar, 2010). In course of time where the industrial revolution occurred in western countries and usage of the fossil fuels increased rapidly, on the other side the natural buffering system for climate change forests, were destroyed indiscriminately for want of fuel, fodder and timbers in the developing countries. These factors were intensified by the human activities in the past 250 years, which had tremendous impact on the climate system. According to the IPPCC the green house gas emission could cause the mean global temperature to rise by another 1.4oC to 5.8oC. Already the symptoms of climate change were observed at a faster rate in the artic and under artic regions through melting of the frozen ice which have danger of submergence of the coastal zones. In the case of the inland water source, there is tremendous change in both surface as well as ground water due to erratic rainfall and occurrence of frequent droughts. Many studies (Parry et al., 1999; Darwin, 2004; Olesen and Bindi, 2002; Adams et al.,2003 and Tsvetsinskaya et al.,2003) find that region-specific analysis is required to evaluate the agronomic and economic impact of weather changes in more detail.
