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. 

South Asia: Water deficits forecast in Gujarat, surpluses in eastern Afghanistan

South Asia: Water deficits forecast in Gujarat, surpluses in eastern Afghanistan

The March through May forecast indicates some relief from water deficit conditions for many parts of India. However, severe to extreme deficits are forecast to persist in Gujarat and moderate deficits are forecast in Uttarakhand, southern India, and Sri Lanka. Surpluses ranging from moderate to exceptional are forecast for the eastern Ganges Basin, the eastern two-thirds of Nepal, and Bangladesh. Surpluses are also expected along the northern tributaries of the Indus River in Pakistan and in eastern Afghanistan.

United States: Exceptional water deficits forecast AR, MO; surpluses in ID

United States: Exceptional water deficits forecast AR, MO; surpluses in ID

Though the extent of exceptional deficits from Missouri to the Gulf and to the Atlantic is expected to recede from March through May, exceptional deficits will persist in Arkansas, Missouri, and western Illinois, and moderate deficits will emerge throughout much of the US east of the Mississippi. Surpluses are forecast for the Pacific Northwest, Idaho, northern Nevada, Central California, western Nevada, and western Colorado and are expected to be exceptional in Idaho, parts of Central California, and along the Columbia River.

Southeast Asia & the Pacific: Water deficits forecast for Thailand, western Cambodia, Papua New Guinea

Southeast Asia & the Pacific: Water deficits forecast for Thailand, western Cambodia, Papua New Guinea

For the next three months severe to exceptional water deficits are forecast to persist in Cambodia, particularly in the west, and severe to extreme deficits will emerge throughout much of Thailand. Deficits are also forecast for southern Myanmar and Papua New Guinea. Both deficits and surpluses are forecast in Laos during this period and in Vietnam, though surpluses will dominate Vietnam’s central coast. After May deficits of varying intensity are forecast for much of the region and are expected to be of greatest severity in Papua New Guinea and Indonesian Borneo. 

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.
