Climate change is unequivocal, impacting the world to varying extent and intensities. However, ecologically fragile and economically weaker communities are more vulnerable to extreme climate events. Geo-politically, the North-Eastern region of India is also known for its volatile and sensitive nature. Moreover, owing to its spatio-ecological instabilities related to the eastern Himalayan ecosystem, international borders, trans-boundary river basins and pervasive socio-economic turmoil make India’s North-Eastern region to be particularly vulnerable to the effects of climate change. Thus, this article is an attempt to evaluate climate vulnerability to different states of Northeast India. It is based on secondary sources of data gathered from different agencies. This study incorporated IPCC’s SREX framework (2014) that has also been used by DST (2020). An index-based approach is utilised where proxy indicators that highlight important components of vulnerability (Exposure, Sensitivity and Adaptive Capacity) are chosen and finally Climate Vulnerability Index (CVI) is developed. Results reveal that Arunachal Pradesh is the most vulnerable, while Assam is the least vulnerable to climate vulnerability on account of its robust infrastructure than other states of Northeast. This vulnerability evaluation will help these states to prioritise adaptation planning, emergency preparedness, promoting environmental awareness and focusing on advanced infrastructure development to reduce climate vulnerability in this region by ranking and identifying the most vulnerable states.
