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 farmers’ revenues, consumer demands, and market conditions. We estimate Composite Entropy Index (CEI) as a measure for crop diversification in Karnataka and quantify the impacts of climatic and economic factors. We construct CEI for all the districts across Karnataka from 1998 to 2014. The results from our model indicate that after controlling for economic factors, 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.
