Spatial distribution of heatwave vulnerability in a coastal city of Bangladesh

While extreme heat events received wider attention in recent years, understanding heatwave vulnerability is still a challenging task that requires clear of range location-dependent climatic, socio-economic, physiological, and environmental parameters. This study investigates the spatial distribution Chattogram City Corporation (CCC) — commercial capital Bangladesh. A index (HVI) was developed, including various parameters related to three latent variables exposure, sensitivity, adaptive capacity derived using remote sensing socio-economic data. Factor analysis performed assess all HVI. Besides, autocorrelation, cluster outlier analyses, hot spot were carried out investigate shows HVI CCC, which spatially associated with individual total seven wards (smallest administrative zone CCC) found be very highly vulnerable heatwave. further reveals randomly distributed throughout city, although high land surface temperature concentrated existing built-up areas. It also identified major spots CCC. The methodology findings this will interest policymakers city planners prepare mitigation plans, policies, strategies mitigate hazard.
