Who Is Vulnerable and Where Do They Live? Case Study of Three Districts in the Uttarakhand Region of India Himalaya

Abstract

Uttarakhand, India, is a dynamic region. It is frequently exposed to natural hazards and is experiencing rapid urbanization. However, the interaction of the increase in people, the built environment, and vulnerability to natural hazards is poorly understood. We model the relationship between urbanization and hazards for 3 cities (Almora, Nainital, and Champawat) and their surrounding subdistricts in the region using a social vulnerability framework. We apply the framework by using principal component analysis to identify socioeconomic vulnerability indicators and built-environment vulnerability indicators. The results show that higher access to assets reduces vulnerability and that larger households are less vulnerable. We also find that the presence of a bathroom and higher-quality building materials are associated with reduced vulnerability. Bathroom presence is more frequent in cities than in surrounding areas, and the quality of building materials was mixed within cities. Access to assets is higher in the cities than in surrounding areas, but households are smaller in cities. These indicators of vulnerability help to close the knowledge gap and identify who is vulnerable and where they live. This analysis continues to expand the conversation about vulnerability to disasters related to natural hazards in mountain regions.
