Regions forecast to have significant water deficits for the 12-month period November 2021 through October 2022 include: Chile, Texas (U.S), North Africa, Portugal, and Spain. Areas of significant water surplus include: China, India, Southeast Asia, and eastern Australia. This Watch List is based on ISciences Water Security Indicator Model v2 (WSIMv2) 7 February 2022.
Africa: Water surpluses persist in Tanzania & Kenya
Exceptional water deficits in North Africa will diminish but persist, and severe deficits are forecast in Gabon and in Nigeria south of the Benue River. Deficits will also persist in western Zambia and are expected to be extreme on the Kafue River. Moderate to exceptional deficits will emerge in central Botswana. Exceptional surpluses will persist in Tanzania, Kenya, and northern Uganda, but diminish somewhat in northern Madagascar. Surpluses east of Kinshasa in Democratic Republic of the Congo are forecast to increase in both extent and intensity, becoming severe.
Africa: Water deficits persist across North Africa, southern Africa
Though the severity of water deficits across North Africa is forecast to shrink from August through October, the widespread extent of deficits will remain the same. Deficits will also persist in Democratic Republic of the Congo, southeastern Central African Republic, and much of Africa’s southern half, with extreme deficits forecast to persist in northern Zambia through November. From November through January nearly all of Africa is forecast to experience some degree of water deficit, primarily moderate.
ISciences Worldwide Water Watch List August 2016
