Observational data shows that there have been significant regional variations in climate change patterns across India. This study examines the effects of climate change on yields of rice across different climatic zones in the former state of Andhra Pradesh. The study uses district level panel data for 30 years (1981–2010) to analyze the influence of climatic variables like rainfall, maximum temperature and minimum temperature on rice yields at the agro‐climatic zone level. Analysis of data shows that the degree of impact of climate on yield of rice is varied across different climatic zones in the former state of Andhra Pradesh. Climatic zones which have traditionally higher temperature and lesser rainfall are more susceptible to variations in climate than others. Though the negative impact of temperature is similar among all the zones, there are observable spatial variations and differences in the degrees of impact The study also found that the impact of irrigation is significantly higher in traditionally drier zones than others. Given significant regional variations on climate change impact, policy makers, administrators and crop scientists have to design micro‐level mitigation and adaptation techniques.
