Horn of Africa: flooding risk

This map illustrates the Horn of Africa's risk of floods for the population, which is concentrated around the Shabeelle, Juba, Awash and Tana Rivers.

The map, biased by the fact that it only considers population density as a measure of exposure, shows the intuitive result that the risk of flooding is greatest in the most populated regions of Ethiopia, Kenya, and Somalia, where large percentage of the population lives along major rivers (e.g. locations of Addis Ababa, Nairobi). For flooding risk, a more detailed analysis beyond the scope of the project may be necessary - one that considers that the headwater areas might not be as exposed as the downstream areas and that there may be different levels of flood control measures like dams and levees on different rivers.
