Assessing Health and Community Resilience to Compounding Multi-Hazards

Changing climate and increasing urbanization have significantly amplified the frequency and intensity of extreme weather events. These events trigger cascading, multidimensional impacts, including physical destruction, financial losses, social disruptions, and both short- and long-term consequences for the health and well-being of affected populations. International efforts, such as the Lancet Countdown on Health and Climate Change, have highlighted the profound effects of climate events on human health. Despite consistent progress by the multi-hazards community in developing methods to assess the co-occurrence of disasters and the cascading impacts of multi-hazards, the susceptibility of populations to compounding multi-hazards remains underexplored in the context of health and community resilience. Our study addresses this gap by analyzing global data on extreme weather hazards from 2003 to 2021 at a 0.25° resolution, alongside the characteristics and resilience of exposed populations, using tools such as the Flood Resilience Measurement for Communities (FRMC) and the World Risk Poll Resilience Index.
