Australia & New Zealand: Water deficits forecast in southwestern Victoria, New Caledonia

Australia & New Zealand: Water deficits forecast in southwestern Victoria, New Caledonia

Despite recent flooding in northern Tasmania, water deficits are forecast to persist in western Tasmania through April, with greatest severity in August. Deficits in New Caledonia are forecast to persist through October; deficits across some far northern regions of Australia may linger through November; and deficits in the southwest tip of Western Australia, south of Adelaide, and in the Melbourne area will persist through April. Water surpluses are forecast for the Fitzroy River Basin and southwest of there, also in the Upper Murray River catchment.

East Asia: Water surpluses to persist on Yellow River & lower Yangtze River

East Asia: Water surpluses to persist on Yellow River & lower Yangtze River

Moderate to exceptional water surpluses are forecast to persist in China along the Yellow River and the lower reaches of the Yangtze River through October. Deficits will continue to emerge in Shandong, eastern Yunnan, and western Guangxi. Widespread deficits are forecast for the Korean Peninsula from September on, and deficits will continue to emerge in Southeast and Northeast China. Deficits may recede in Honshu, Japan in October before re-emerging.

South America: Exceptional water deficits persist in central Brazil

South America: Exceptional water deficits persist in central Brazil

South America is forecast to transition away from widespread exceptional water deficits after October. However, until then exceptional deficits are forecast for much of Brazil north of Rio, along with deficits of varying severity elsewhere in South America. By December the extent of exceptional water deficits in Brazil will diminish except along the Amazon River and in Amapá and Maranhão. From November on moderate deficits are forecast in Colombia, Venezuela, Guyana, Suriname, French Guiana, Ecuador, Peru, Chile, and Rio Grande do Sul, Brazil.

Europe: Water deficits forecast for Eastern Europe, surpluses in Luxembourg

Europe: Water deficits forecast for Eastern Europe, surpluses in Luxembourg

Water deficits are forecast to persist over the next several months in Finland, southern Norway and Sweden, the Baltics, eastern Germany, Eastern Europe, the Iberian Peninsula, and the Mediterranean. Water surpluses are forecast to persist, though diminished in extent and severity, in the United Kingdom, northern France and across the border into Germany. From November on, a transition to water surpluses across Northern Europe, the Baltics, European Russia, and later, Central Europe, is forecast.  Deficits remain in the forecast for countries along the Mediterranean Sea through April.

Africa: Water deficits persist across North Africa, southern Africa

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.

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.
