Geographies of vulnerability to climate change: empirical evidences from the Indian Himalayan foothills

In India, there is a need for field survey-based vulnerability studies to overcome the uncertainties that exist in regional model-based climate vulnerability assessments. Therefore, the present study explored the regional patterns and their associated determinant factors of climate change vulnerability in the Himalayan Foothills of West Bengal to determine which regions are more vulnerable in the same geographical space. The research was conducted in the 13 Community Development Blocks (CD Blocks) of the Himalayan Foothills of West Bengal, India. The Socio-Economic Vulnerability Index (SEVI) was proposed to fulfill the above objectives. The present SEVI was comprised of seven subdimensions of climate change vulnerability: namely, climate variability, natural disaster risk, socio-demographic profile, livelihood strategy, environment profile, livelihood security, and accessibility of basic infrastructure covering three major vulnerability components, exposure, adaptive capacity, and sensitivity. The primary field survey was conducted using a structured questionnaire for data collection comprised of 22 indicators covering seven significant dimensions. The results suggest that Alipurduar-II, Jalpaiguri, and Mal, which are highly exposed to climate variability and natural disaster risk at the same time, have low adaptive capacities. The livelihood strategy, socio-demographic, and environmental profile were the determining factors of regional vulnerability in the study area. The CD blocks Falakata, Dhupguri, and Rajganj showed a higher adaptive capacity and were less sensitive to climate change vulnerability, even though exposure to climate change was the same in the entire area. The survey findings indicate that adaptive capacity is high in Falakata and Rajganj and these areas are less susceptible to climate change vulnerability. Finally, the appropriate recommendation is to develop a basic physical infrastructure, including bridges over the rivers and concrete village roads in all the flood-prone villages in the entire Himalayan Foothills of West Bengal for better connectivity. Also, household food availability should be secured through public distribution systems that develop the coping capacity of the region as a whole.
