Drought and Displacement Remain the Horn's Largest Shared Emergency

The Horn of Africa sits across one of the world's most rainfall-variable zones. Much of the region depends on two rainy seasons — the long rains around March to May and the short rains around October to December — and the failure of consecutive seasons is the single largest driver of humanitarian need across all four countries.

The mechanism is consistent. Pastoralist communities lose livestock first, because animals cannot be moved fast enough to water. Terms of trade turn against herders as animal prices fall and cereal prices rise. Families move toward towns, water points and aid distribution, and displacement concentrates in settlements that were not built for it.

Displacement in the Horn is overwhelmingly internal rather than cross-border. People move within their own countries, to the outskirts of Mogadishu, Baidoa, Dhusamareb, or to towns in the Ethiopian lowlands. Camps that begin as emergency settlements frequently become permanent, and a second generation grows up in them.

Climate is not the only variable. Conflict restricts the movement of both herds and assistance, and areas that are hardest to reach are frequently the areas in greatest need. Where drought and insecurity overlap, the response is slower and the outcome worse.

There is a longer structural question underneath the emergency cycle. Pastoralism has been the rational land-use strategy for these rangelands for centuries precisely because it is mobile. Where that mobility is constrained — by conflict, by land enclosure, by settlement — the system's resilience falls.
