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

Abstract

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 the non-climatic factors had positive and significant impact on food security except urbanization while climatic factors viz. maximum temperature had negative and significant impact and minimum temperature and rainfall had insignificant impact on food security. Furthermore, the impact of climatic and non-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.

Rainfall variability, rainfed agriculture and degree of human marginality in North Guanajuato, Mexico

“…Climate change, agricultural productivity, food security and poverty are tightly correlated (Kumar & Sharma, 2013). Research on these variables must continue to be conducted locally, regionally and nationwide to provide proposals and raise the quality of life of the population that depends on low-yielding, rainfed agriculture.…”

Climate Change and its impacts on Indian agriculture: An Econometric analysis

“…Climate change is not a new phenomenon in the world (Kumar & Gautam, ; Kumar & Sharma, ). The rise in temperature of the earth surface and in atmosphere, variation in rainfall, declining groundwater, flooding due to high rainfall, drought, soil erosion, heavy wind, rising sea level due to melting of glacier, cyclone, wind speed, hail storm, fog, earthquake and landslide etc.…”

Linking Food Security with Household’s Adaptive Capacity and Drought Risk: Implications for Sustainable Rural Development

“…Droughts directly affect agriculture (Edame et al 2011), while they indirectly affect economic growth, income distribution, household welfare and agricultural demand (Schmidhuber and Tubiello 2007). Overall impact of drought may be reduction in agricultural production, purchasing power and employment opportunities resulting into serious threat of hunger, food insecurity, poverty and malnutrition in any region of the world (Kumar and Sharma 2013;Sam et al 2016).…”
