Cropland Flood Exposure

Flood risk is usually counted in people. This page counts it in farmland: how much cropland in each district sits inside the 100-year flood extent. The districts at the top are the haor basin and the northern char belt, where a single early flood can take the Boro rice crop before harvest.

Method and sources

Cropland: ESA WorldCover 2021 cropland class intersected with the GloFAS v2.1 100-year river-flood extent, summed by district (FAO GAUL 2015 boundaries). This is modelled exposure of farmland to a design flood, not an annual loss estimate. Related: the exposure atlas (population layers) and the haor flash-flood early warning for the live Boro-harvest view.
