Impact of Climate Change on Paddy Yield in Bastar District of Chhattisgarh

Abstract

Agriculture and forest product collection are the economic foundations of the Bastar district. Paddy and maize are widely grown in the Bastar region. Paddy is grown in 76 percent of the gross cropped area in Bastar district. To assess the impact of climate change on paddy productivity a simple ordinary least square (OLS) Regression analysis have been analysed. Observation revealed that the rainfall during the month of June to September affected the crop yield positively, Monsoon rainfall affects more the crop yield negatively. Bastar district is mainly rainfed and only 2.14 percent area near to the water resources can be irrigated, the lack of irrigation effects the crop yield greatly hence, any increase in rainfall in the germination and booting period (June to August) will help in increase the productivity of crop. The month of or before harvesting if gets rain, it can destroy the standing crop and cause huge lose to the production.An increase in annual maximum Temperature affects the paddy crop productivity negatively whereas productivity increases with every per cent increase with the annual minimum Temperature. Paddy is a tropical and subtropical crop hence, the result had positive relationship with maximum Temperature, Excessive rainfall can negatively or positively impact crop yield.The study suggests to develop such varieties which can withstand with minimum Temperature.
