Widespread surpluses are forecast for Southeast China, which may be of exceptional severity in Fujian and along the Pearl River (Zhujiang). However, both deficits in the North and surpluses in the South are forecast to diminish in severity during the latter part of the forecast period.

Australia: Exceptional water deficits to persist near Melbourne, Tasmania, Perth; north may transition to 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.
