Multi-Hazard District Exposure Atlas
How many people and how much farmland sit in each district's flood, low-elevation, surface-heat and air-pollution exposure, built from primary remote-sensing layers and population-weighted with WorldPop. Switch the map layer with the dropdown.

Sources and method
Flood: GloFAS v2.1 100-year river-flood hazard (JRC/Copernicus, ~1 km), population inside the modelled extent. Coastal: FABDEM bare-earth elevation (30 m), population below 5 m. Heat: MODIS MOD11A2 land-surface temperature (NASA, 1 km), warm-season (March to May) 2020 to 2024 mean, population-weighted. Air: satellite-derived surface PM2.5 from van Donkelaar et al. (ACAG, Washington University), accessed via the Open Earth Engine community catalogue and the basis of the State of Global Air annual reports, ~1 km, 2020 to 2022 mean, population-weighted. Population: WorldPop 2020 (100 m), summed within district polygons; the WorldPop 2020 national total is about 141 million, roughly 14 percent below the 2022 census count of 165.2 million because the 2020 grid is an unadjusted model, so the percentages are shares of WorldPop-modelled population, not of the census total. Boundaries: FAO GAUL 2015 (ADM2).
The combined exposure rank is the mean of each district's within-country percentile rank across the four hazards (equal weights, no hidden weighting). It is a relative ranking across the 64 districts, not an absolute risk score. Surface temperature is reported as a heat-intensity layer, not a clinical heat index.
