Flood Exposure Analysis
People and land within modelled flood extents, by return period
Estimated population and agricultural land falling inside modelled riverine flood
extents across the Greater Horn of Africa, for the 20-, 50- and 100-year return
periods. Higher return periods describe rarer but more severe floods, so exposure
rises as the flood footprint grows.
