Analysis of socioeconomic vulnerability for cyclone-affected communities in coastal Odisha, India

This research is based on the assessment of vulnerability for six of the most cyclone prone coastal blocks in the state of Odisha, India. The necessary primary data were collected from 450 sample households through a structured questionnaire survey. The secondary data related to the demographic profile of blocks were taken from the published census reports. The socioeconomic vulnerability score for each block is developed using a set of 29 indicators selected from the literature review and in consultation with experts. The selected indicators cover the IPCC dimensions of vulnerability (adaptive capacity, sensitivity, and exposure to climate change led hazards). Results of this research conclude that among the six blocks, Soro block is the most vulnerable and Rangeilunda block is the least vulnerable. The most influential factors for socioeconomic vulnerability in the study area include population density, population growth rate, percentage of rural population, distance of cyclone shelter, unemployment, adequate toilet facility, frequency and impact of flood and cyclone, and lack of logistics supports during cyclone. The findings of this study advocate that the interventions for vulnerability reduction and development of adequate coping mechanism should be made for the communities living in such areas.
