Long-term drought continued across areas of the Greater Horn of Africa (eastern Kenya, southeastern Ethiopia, northern/central Somalia and Djibouti) and southern Africa. In Kenya, two million people were in need of food aid (WFP). Widespread crop failure over much of Mozambique, southern and eastern Zimbabwe, as well as adjacent parts of Malawi and South Africa, was the result of less than half the normal rainfall during the rainy season. For the latest African analysis and forecast, see the Famine Early Warning System Network.
