Europe: Water surplus to persist in Ireland, Central Europe, & European Russia

Europe: Water surplus to persist in Ireland, Central Europe, & European Russia

The forecast indicates a transition in April to water deficits across much of Europe, but until then widespread surpluses will persist in Northern, Central, Eastern Europe, and European Russia and are expected to be exceptional in Russia, northern Poland, northwestern Ireland, and along the Dnieper River in Ukraine. Deficits will continue to emerge in Southern Europe, particularly the Iberian Peninsula, but will retreat significantly in France, persisting only along the southern coast. Intense deficits will emerge in Crimea, and will persist in northern Finland and northern Norway.

ISciences Worldwide Water Watch List January 2018

Regions forecast to have significant water deficits for the 12-month period from October 2017 through September 2018 include: Missouri (US), Brazil, Spain, Portugal, Morocco, Turkmenistan, Inner Mongolia (China), and South Australia and Tasmania (Australia). Areas with a forecast of significant water surplus include: Ireland, Poland, and Bangladesh. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 10 January 2018.

Europe: Water surpluses to spread in Central Europe, esp Poland

Europe: Water surpluses to spread in Central Europe, esp Poland

The extent of exceptional water deficits will diminish considerably through February in Southern Europe leaving primarily moderate deficits on the Iberian Peninsula, France, and Italy, with more intense deficits in southeastern France. Exceptional surpluses will continue to emerge in western European Russia and Poland and will emerge in Belarus. Surpluses of varying severity will emerge in greater extent in Central and Eastern Europe. After February the extent and intensity of surpluses in Russia, Central, and Eastern Europe will diminish but surpluses will remain intense in central Poland. 

Middle East: Widespread deficits forecast to persist, esp Israel & Lebanon

Middle East: Widespread deficits forecast to persist, esp Israel & Lebanon

Widespread exceptional deficits observed in the prior three months are expected to moderate considerably through February, though extreme deficits are in the forecast for Lebanon and Israel. Deficits of slightly lesser intensity, but still severe, are forecast for southeastern Turkey, Syria, pockets throughout Iraq, central Iran, northern Saudi Arabia, and southwestern Yemen. Primarily moderate deficits are forecast nearly everywhere else. After February, deficits on the Arabian Peninsula are expected to ratchet up in intensity, and moderate deficits will continue to emerge in Turkey. 

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.
