ISciences Worldwide Water Watch List September 2023

ISciences Worldwide Water Watch List September 2023

The forecast for September 2023 expects significant water deficits for the 12-month period of June 2023 through May 2024 in northern Africa, northern and western South America, the Middle East, and most of Canada’s provinces. Areas expected to experience surplus include the western United States, north-central Australia, and southeastern 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.
