Impact of Climate Change on Food Grain Productivity in Mirzapur District of Uttar Pradesh

The paper has looked into the impact of climate change on productivity of foodgrains in the Mirzapur district of Uttar Pradesh by considering two major factors, viz. temperature and rainfall for the period 1950–2013. The regression analysis has shown that a drop in mean minimum temperature has a positive impact while rise in mean maximum temperature has a negative impact on rice productivity. A rise of 1°C in mean maximum temperature may decrease the rice yield by about 200 kg/ha. The rainfall has depicted a positive relation with rice yield. In the case of wheat, the rise in mean maximum temperature as well as increase in rainfall have a positive impact on its yield.
