Description
Summary:•Crop yields of Rice, Groundnut and Tobacco are significantly impacted by climatic variables in the state.•Influence of exogenous variables is more than climatic variables for commercial crops like Cotton and Tobacco.•Crops cultivated in Rabi (Tobacco) are more susceptible to changes in climatic variables.•Drought crops like Jowar are able to withstand uptick in temperatures better than any other crops. Observed meteorological data demonstrates that temperature has increased by 0.74°C in the last hundred years with the bulk of the warming occurring in the last 50 years. This paper examines the impact of climate change on five major crops in the former state of Andhra Pradesh using district level panel data for the period 1981–2010. Analysis of data shows that crop yields are significantly impacted by climate for rice, tobacco and groundnut. Crops grown in rabi are more susceptible to changes in climate than those in kharif, while drought crops like jowar are found to withstand changes in climate better than others.
