Europe: Water deficits throughout Continental Europe

The forecast through April 2023 predicts severe to exceptional deficits in central France, central Sweden, and coastal areas of the Balkans. Pockets across northern Italy, northeastern Spain, and central Poland can expect deficits of similar intensity. Switzerland, Austria, eastern Hungary, eastern Slovakia, and Romania are expected to experience areas of moderate surplus.

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.
