Africa: Intense water deficits ahead for central Somalia
The forecast through March 2020 indicates that water deficits in Africa will shrink and downgrade considerably, but exceptional deficits will emerge from central Somalia into Ethiopia. Surpluses in East Africa will remain widespread, particularly in Tanzania and Kenya. Other areas with a forecast of surplus include the Nile River through Egypt and nations on the north coast of the Gulf of Guinea.
Africa: Water deficits will downgrade overall
The forecast through August 2019 indicates moderate water deficits across northern Africa with large pockets of exceptional deficit in Libya, Egypt, and Sudan. The southern Sahara and the Sahel will be near-normal, and deficits in the Horn will downgrade. Mild deficits will cover much of southern Africa, punctuated by surpluses in East Africa and some pockets of intense deficit from Cameroon through Republic of the Congo, in southern Angola, northern Namibia, and western Botswana.
Africa: Water deficits forecast to increase across the Sahel
The forecast through April indicates that water deficits will downgrade in the southern half of the continent, becoming primarily moderate across the central breadth and mild in the south. Deficits in the north will increase and intensify, with moderate to extreme deficits in the Sahara and deficits reaching exceptional intensity in parts of the Sahel and into western Ethiopia. Intense deficits will linger in Cameroon, Equatorial Guinea, and Gabon. Surpluses will persist in western Tanzania.
