The present study was conducted at the department of agrometeorology, IGKV Raipur (C.G.) from 2019 to 2021, to assess the zone level vulnerability in three agro-climatic zones of Chhattisgarh with respect to climate change. The data on various components were collected from the Census directorate of Chhattisgarh, department of agrometeorology, Raipur and the report of directorate of economics and statistics Raipur, Chhattisgarh for the period of 2000 to 2018 and divided into three different study periods i.e. 2000-2005, 2006-2010 and 2011-2018. We used Hiremath and Shiyani and Iyenger and Sudershan's methodology to contract the vulnerability and composite vulnerability index. The outcome of this study indicated that the agricultural sector played a major role and contributed significantly to quantifying the vulnerability followed by climatic and demographic indicators during all three study periods. Results of the composite vulnerability index indicated that Bastar Plateau Agro-Climatic Zone (BP ACZ) was categorized as a more vulnerable zone followed by the Northern Hills agro-climatic zone (NH ACZ) and Chhattisgarh Plain Agro-Climatic Zone (CGP ACZ) in decreasing order of vulnerability in all the three study periods. Zone wise classification of degree of vulnerability, Chhattisgarh Plain Agro-Climatic Zone (CGP ACZ) and the Northern Hills Agro-Climatic Zone (NH ACZ) was categorized as highly vulnerable category, while Bastar Plateau Agro-Climatic Zone (BP ACZ) falls under the Very highly vulnerable category, during all the three-study period. We have not found the less vulnerable, moderately vulnerable and vulnerable zone during all the three study periods.
