Vulnerability and risk perceptions of hydrometeorological disasters: a study of a coastal district of Odisha, India

Climate change has increased hydrometeorological disasters all over the world. The increase in the occurrences of hydrometeorological disasters has brought into focus the preservation and protection of the coasts. This study, thus, makes a comprehensive assessment of the Puri district on the east coast of India, which is most affected by hydrometeorological disasters. We identify the hotspots by applying the analytical hierarchical process to the integrated coastal vulnerability index in ArcGIS. Further, employing the ordered logistic regression model, we identify the household characteristics determining disaster risk perception among the vulnerable households. Results tend to indicate that the region falling in and around Puri-Konark coastal belt are the most vulnerable ones. The households, which are economically deprived, engaged in the primary sector, and having more dependent members, perceive greater risks of hydrometeorological disasters. The proximity to the sea and river also increases their perceived risks. The findings suggest risk-mitigating efforts by prioritizing the needs of the poor and vulnerable communities while guaranteeing access to opportunities.
