Disparities in exposure to hydrogeomorphic hazards in Bangladesh.

ABSTRACT: Natural hazards can impair socio-economic development. While population exposure to various natural hazards has been quantified, the exposure to hydrogeomorphic hazards - involving water-induced landscape changes - remains unknown. Using high-resolution hydrogeomorphic modelling, combined with population and wealth data, this study provides a national-scale spatial assessment of exposure to hydrogeomorphic hazards across population and wealth groups, taking Bangladesh as a case study. Bangladesh is an exceptionally geo-dynamic country, where multiple hazards coincide with a dense population (1300 people per km²) and a high poverty rate (20%). Here we show that over 22 million people, making up 13% of the population, live within hydrogeomorphically unstable regions. Of the 22 mil
