Europe: Water deficits in Finland, surpluses forecast for western European Russia

Europe: Water deficits in Finland, surpluses forecast for western European Russia

From March through May widespread water surpluses are forecast to emerge in western European Russia, which may be exceptional near St. Petersburg and to the east. Severe to exceptional deficits are forecast for Finland, Estonia, much of Latvia, southern Sweden and Denmark. Scattered moderate deficits are forecast for much of Western and Central Europe with pockets of greater severity in central Germany, southern Austria, Macedonia, and from Rome to Palermo, Italy. Surpluses are forecast for Switzerland and eastern Romania. The June through August forecast indicates primarily moderate deficits throughout most of Europe with widespread exceptional deficits persisting in Finland and Estonia. 

South America: Water deficits in eastern Brazil, surpluses in northern Peru

South America: Water deficits in eastern Brazil, surpluses in northern Peru

Though the extent of water deficits in South America is expected to shrink March through May, deficits are forecast in central and eastern states of Brazil, western French Guiana into eastern Suriname, Bolivia, Chile, and coastal Peru. Surpluses are forecast in Paraguay, in a line down western Argentina, in central Buenos Aires Province (Argentina), in Rio Grande do Sul and Paraná (Brazil), northern Peru, northern Guyana, Suriname, and parts of Ecuador. From June through August deficits are forecast to persist across Brazil’s mid-section and emerge in Piauí and across northern Brazil. Deficits are also forecast for Bolivia, Colombia, Venezuela, Guyana, Suriname, French Guiana, coastal Peru, and northern Chile. Surpluses will persist in aforementioned areas of Paraguay and Argentina.

Australia & New Zealand: Water deficits forecast to persist in Queensland

Australia & New Zealand: Water deficits forecast to persist in Queensland

Widespread exceptional water deficits in South Australia are forecast to nearly disappear from March through May leaving moderate deficits, but widespread deficits of varying severity are forecast in eastern Australia, particularly Queensland, with exceptional deficits in Central West, Queensland. Primarily moderate deficits are forecast for New South Wales, much of Victoria, and in Western Australia south of Perth. After May the forecast indicates considerable improvement with the near-absence of extreme to exceptional deficits, though severe deficits will emerge in eastern Tasmania.

Middle East: Water deficits in Turkey, Saudi Arabia, Yemen

Middle East: Water deficits in Turkey, Saudi Arabia, Yemen

The extent of exceptional water deficits in the region is expected to nearly disappear March through May, but moderate to severe deficits are forecast for the Arabian Peninsula and Turkey. Deficits are also forecast for Syria, Jordan, Lebanon, Israel, southern Iraq, and coastal Georgia. Surpluses are forecast in Iran from the central Persian Gulf inland to the center of Kerman Province. From June through August the extent and severity of deficits will increase throughout much of the region, particularly on the Arabian Peninsula.

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. 

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.
