The present research work entitled “Impact of rainfall on production and productivity of horticultural crops and vulnerability assessment in different districts of Chhattisgarh Plain Zone (1)” was carried out to find the trend of annual rainfall, area and production, correlation analysis in order to study the impact of annual and seasonal rainfall with production and productivity of fruits and vegetables respectively followed by vulnerability assessment with respect to climate change in eight districts of Chhattisgarh plain zone 1, i.e, Raipur, Mahasamund, Dhamtari, Durg, Rajnandgaon, Kanker, Balodabazar and Gariyaband. The time series data was collected for 16 years from 2004-2020 on all the demographic, climatic, agricultural, occupational and geographic indicators. Patnaik and Naraynan method was used for calculating the vulnerability index followed by Garret’s ranking method in order to calculate the percentage vulnerability of the districts. Trend analysis was done using linear trend method and correlation analysis was carried out using MS Excel software. Also, Weather Cock software was used to calculate annual rainfall from 1991-2020.
As per the analysis of overall vulnerability index followed by Garret’s ranking, district Mahasamund was found to be the most vulnerable while district Rajnandgaon was observed as least vulnerable for climate change among the eight districts of Chhattisgarh plain zone 1. Assessment of vulnerability index exemplifies the impact of climate change on vulnerability in terms of exposure, sensitivity and adaptability.
