In India, deficits will increase and intensify, blanketing a vast extent across the country’s girth, and will include exceptional deficits throughout Gujarat in the west and severe to exceptional deficits from Madhya Pradesh through Karnataka, as well as in Punjab, Rajasthan, Haryana, and India’s Far Northeast.

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.
