Africa: Exceptional water deficits to diminish considerably

Africa: Exceptional water deficits to diminish considerably

Overall the extent of exceptional water deficits is expected to diminish considerably September through November leaving moderate deficits in the south and extreme to exceptional deficits across the southern Sahara. Exceptional surpluses are expected to persist in southeastern Tanzania, and while those areas of surplus will moderate slightly after November, surpluses will emerge throughout the country and may be particularly intense in Dodoma Region. Except for surpluses in East Africa, primarily moderate deficits are forecast for most of the continent from November through spring next year.

Africa: Exceptional water deficits in Sub-Saharan Africa to moderate

Africa: Exceptional water deficits in Sub-Saharan Africa to moderate

Though the extent of exceptional water deficits in Africa is forecast to shrink from September through November, much of the continent will remain in conditions of deficit. Surpluses are forecast to persist in Burkina Faso, Northwest Province in Cameroon, southern Sudan, eastern South Sudan, and Tanzania during this period. From December through February nearly all of Africa is forecast to experience some degree of water deficit, though less severe than in prior months. Primarily moderate deficits are forecast from the northernmost countries down through the Democratic Republic of the Congo, with only mild deficits forecast in southern Africa.

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.
