Impact of climate change on agricultural productivity and food security in India: A State level analysis

This paper has analysed the emerging dimensions of food security and trends of crop productivity by using secondary data from 1980–81 to 2014–15 at State level of India and has also identified the impact of climatic and non-climatic variables on food security and crop productivity. The study revealed that the growth rate of foodgrains and non-foodgrains productivity was found positive except for some crops of non-foodgrains at state level with some fluctuations. In case of food security and its component, the result showed that there were wide variations across the states during the study period. The panel data regression results also highlighted that thenon-climaticfactors had positive and significant impact on foodsecurity except urbanization while climatic factors viz. maximum temperature had negative and significant impact and minimum temperatureand rainfall had insignificant impact on foodsecurity. Furthermore, the impact ofclimatic andnon-climatic factors had a mixed effect on crop productivity. The paper suggested that there was need to change the policy in term of building sustainable climate resilient technology, enhancing the agricultural infrastructure and optimizing use of inputs for boosting up the crop productivity and increasing public-private partnerships for sustainable development to solve the problems of food and nutrition at state level.
