Africa

Africa: Severe water deficits in northern Africa, Gabon, & Botswana

Africa: Severe water deficits in northern Africa, Gabon, & Botswana

Severe to exceptional water deficit conditions are expected to continue in the desert regions of the northern nations, Algeria, Libya, Egypt, northern Niger, and northern Sudan. Gabon, Botswana and Madagascar are also expected to experience exceptional deficit conditions in the near term. Surpluses in Tanzania may shift southward in the out months entering early 2018. While conditions moderate across sub-Saharan Africa,  there are indications that moderate to severe deficits may develop across the Sahel and northern Chad and Sudan in the December through February 2018 period.

Africa: Water surpluses forecast for SE Tanzania, NE & coastal Kenya

Africa: Water surpluses forecast for SE Tanzania, NE & coastal Kenya

Severe to exceptional water deficits are forecast across northern Africa, Gabon, central Republic of the Congo, and western Madagascar through July or longer. Moderate to severe deficits are expected in northern Cameroon, eastern Central African Republic, southwestern Ethiopia, western Kenya, Democratic Republic of the Congo, Rwanda, Burundi, Angola, and northern Mozambique. Exceptional surpluses are expected to emerge in northeastern and coastal Kenya, and to re-emerge in south-central Sudan. Surpluses of varying intensity are forecast to persist in southeastern Tanzania, western Zambia, northern Botswana, Zimbabwe, and along South Africa’s border with Botswana. After July deficits in the north will persist, though diminish slightly in intensity and extent.

Africa: Water deficits forecast across the North & Gabon, DRC, Kenya

Africa: Water deficits forecast across the North & Gabon, DRC, Kenya

Widespread exceptional water deficits are forecast to emerge across northern Africa from April through June; deficits of lesser severity are forecast across Africa’s mid-section. Deficits in the Horn of Africa, DRC, and Angola are expected to downgrade to primarily moderate severity. Surpluses are expected in southeast Sudan into South Sudan, southeastern Tanzania, western Zambia, the Okavango Delta in northern Botswana, Zimbabwe, northern South Africa, and northern Madagascar. After June deficits across northern Africa are forecast to recede slightly overall, but severe to exceptional deficits are expected to emerge in southern Somalia, and moderate to severe deficits may emerge in northeast Namibia. 

Africa: Water deficits forecast across the North, Somalia, Gabon

Africa: Water deficits forecast across the North, Somalia, Gabon

Though the extent of exceptional water deficits across the continent will diminish from March through May, severe to exceptional deficits will continue to emerge across northern Africa, especially in Niger. Exceptional deficits are also forecast in southern Somalia and southern Gabon. Deficits are also expected in Congo, Rwanda, Burundi, southeastern Central African Republic, Democratic Republic of the Congo, northern Angola, Uganda, western Tanzania, Kenya, and northeastern Mozambique. Surpluses are expected in southeast Sudan, the Okavango Delta in northern Botswana into western Zambia, Zimbabwe, and northern South Africa. From June through August the overall picture will remain much the same, but worth noting is that extreme to exceptional deficits are forecast for nearly all of Egypt during this period, and deficits will emerge in Somaliland, northern Cameroon, and southern Angola. 

Africa: Exceptional water deficits recede but widespread deficits persist

Africa: Exceptional water deficits recede but widespread deficits persist

The extent of exceptional deficits across the continent will diminish through April, but moderate to extreme deficits will persist across northern Africa and across Africa’s mid-section from Gabon to southern Somalia. Deficits will diminish considerably in Madagascar though persist in the south. Surpluses are forecast in the Okavango Delta in northern Botswana, southern Zambia, Zimbabwe, and western Mozambique. The forecast for May through July indicates a downgrade in the intensity of deficits in the southern Sahel and an increase in the intensity of deficits across northern Africa where extreme to exceptional deficits are expected to emerge in eastern Algeria, northern Niger, Libya, Egypt, and northern Sudan. 

Many analyses reported in ISciences-authored blog posts are based on data generated by the ISciences Water Security Indicator Model (WSIM). Other sources, if used, are referenced in footnotes accompanying individual posts. WSIM is a validated capability that produces monthly reports on current and forecast global freshwater surpluses and deficits with lead times of 1-9 months at 0.25°x0.25° resolution. This capability has been in continuous operation since April 2011 and has proven to provide reliable forecasts of emerging water security concerns in that time-frame. WSIM has the ability to assess the impacts of water anomalies on people, agriculture, and electricity generation. Detailed data, customized visualizations, and reports are available for purchase.
