Abstract:

Changes in climate could significantly impact agriculture. Crop diversification has been used as an indicator to study the impacts of climate change on agriculture in recent literature. Besides climatic factors, crop diversification also depends on economic factors such as farmer’s revenues, consumer’s demands, and market conditions. We estimated Composite Entropy Index (CEI) as a measure for crop diversification in Karnataka and quantified the impacts of climatic and economic factors. We constructed CEI for all the districts across Karnataka from 1998 to 2014. The results from our model indicated that after controlling for economic factors, the climatic factors impact crop diversification significantly. Crop diversification increased in Karnataka due to climate change. Furthermore, our model also highlights the interactive effects of agricultural inputs such as fertilizers and climatic variables such as rainfall on crop diversification

Keywords:

CEI, crop diversification, agro-climatic zones
