ISciences Worldwide Water Watch List March 2017

Regions likely to have significant water deficits for the 12-month period from December 2016 through November 2017 include: Arkansas, Quebec, Brazil, Finland, Denmark, Libya, Niger, Gabon, Madagascar, Saudi Arabia, Yemen, northern Russia, Inner Mongolia, Thailand, western Cambodia, Papua New Guinea, and eastern Australia. Water surpluses are forecast for: Idaho, Central California, southwestern Zambia, the Okavango Delta in Botswana, northeastern Afghanistan, and between the Irtysh and Yenisei Rivers in Russia. This Watch List is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 8 March 2017.

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.
