Assessing socio-economic vulnerability to climate change-induced disasters: evidence from Sundarban Biosphere Reserve, India

Communities in the Sundarban Biosphere Reserve (SBR), India, face very high socio-economic vulnerability to climate change-induced disasters such as cyclones and storm surges. The study identified Basanti, Gosaba, Kultali, Namkhana, and Patharpratima blocks as particularly vulnerable, while Kakdwip, Sagar, and Hingalganj showed high vulnerability. This finding was derived from a pragmatic analysis combining exposure metrics—like storm surge height, flood inundation, and drainage factors—with sensitivity and adaptation data from a field survey of 570 households. The research highlights that constant exposure to extreme weather events, coupled with weak infrastructure and poverty, hinders socio-economic progress. Recommendations for improvement include stronger infrastructure, early warning systems, disaster monitoring centers, better transport connectivity, and enhanced livelihood opportunities. This approach effectively demonstrates the impact of climate change on coastal communities and suggests adaptive measures to mitigate vulnerabilities.
