Flood risk, counted in farmland.

Flood risk is usually counted in people. This page counts it in cropland: how much farmland 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.

At-risk cropland

By district

Ordered by hectares of cropland inside the 100-year flood extent. The bar shows each district against the worst-affected. Share is that district's portion of the national at-risk total. Floodplain population is the share of the district's people who live inside the same 100-year extent. The top ten are shaded.

Method and sources

Cropland: ESA WorldCover 2021 cropland class intersected with the GloFAS v2.1 100-year river-flood extent, summed by district on FAO GAUL 2015 boundaries. This is modelled exposure of farmland to a design flood, not an annual loss estimate. Floodplain population is the district's share of population inside the same 100-year extent. From the BDPolicyLab multi-hazard district layer.
