Canada: Water deficits in Ontario and Quebec

Canada: Water deficits in Ontario and Quebec

The outlook for Canada through December indicates that, overall, the extent of exceptional water deficits will shrink, though a span across central Quebec will persist until March. Deficits of varying severity are forecast for most of Ontario and Quebec. Surpluses are forecast in the southwestern corner of Northern Ontario from Kenora north which are expected to persist through March. Surpluses are also forecast for southern British Columbia near Kamloops and the Peace Country region of Northeast British Columbia through March.

Australia & New Zealand: Water surplus forecast for Murray River Basin through March

Australia & New Zealand: Water surplus forecast for Murray River Basin through March

Exceptional surpluses are forecast to persist through December in central Queensland, along the southwest coast of Western Australia, and east of Spencer Gulf. Moderate to exceptional surpluses are forecast in the Murray Basin through March, and moderate deficits along South Australia’s Limestone Coast and southern Tasmania. Deficits in New Caledonia are expected to diminish.

Europe: Water deficits, especially Scandinavia, Spain & Ukraine, surpluses in western European Russia

Europe: Water deficits, especially Scandinavia, Spain & Ukraine, surpluses in western European Russia

For the next three months water deficits will continue to dominate much of Europe especially Spain, Scandinavia, the Baltics, and Ukraine. Although the severity will diminish the extent will increase. Exceptional surpluses are forecast for western European Russia. From January through March deficits are expected to diminish in both extent and severity across Europe. Surpluses will continue to emerge in European Russia during that period and will also emerge in the Baltics and southern Scandinavia.

Middle East: Water deficits persist, esp Syria, Iraq west of Euphrates, & SW Yemen

Middle East: Water deficits persist, esp Syria, Iraq west of Euphrates, & SW Yemen

Widespread water deficits are forecast to persist throughout the Middle East, but the severity of deficits will diminish October through December and continue to diminish through March. Exceptional deficits are, however, forecast for southwestern Yemen through December. Moderate to severe deficits will emerge in northern and eastern Turkey, and moderate deficits will emerge nearby in northwest Iran. Severe deficits are forecast for Syria and for Iraq from the Euphrates west. 

Africa: Exceptional water deficits shrink, surpluses persist in White Nile Basin

Africa: Exceptional water deficits shrink, surpluses persist in White Nile Basin

The extent of exceptional deficits across Africa is forecast to shrink considerably through December. However, moderate to extreme deficits are forecast for eastern Central African Republic and Republic of the Congo, and exceptional deficits are also expected along rivers in South Sudan, Uganda, Somalia, and Kenya. Surpluses are forecast in southeastern Sudan into South Sudan and for the Nile. The forecast for January through March indicates primarily moderate water deficits across northern Africa, a scattered band of both deficits and surpluses across the Sahel, and primarily abnormal to moderate deficits 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.
