South Asia: Water deficits forecast to persist in India, transitioning to surpluses in June

Widespread water deficits, with large areas of exceptional deficits, are forecast for much of India through April 2016. Both deficits and surpluses are forecast during this period for southeastern India and Sri Lanka. Deficits are expected to transition to moderate to severe surpluses June through October. Moderate surpluses are also forecast to emerge along the northern portion of the Indus River in Pakistan in August. 

South Asia: Water deficits expected in Southern Afghanistan, Pakistan, and portions of India; surpluses forecast in southeastern India, Sri Lanka, northeastern Afghanistan, and Nepal

The forecast through September 2016 indicates water deficits in southern Afghanistan, Pakistan, and portions of India, with many areas experiencing both deficits and surpluses. Surpluses are forecast in southeastern India, Sri Lanka, northeastern Afghanistan, and Nepal.

 

South Asia: Exceptional deficits forecast across much of India through February; notable surpluses in southeastern India

The forecast through August 2016 indicates water deficits in southern Afghanistan, Pakistan, and most of India, with some areas experiencing both deficits and surpluses. Notable surpluses are forecast in southeastern India. Surpluses are also forecast for Sri Lanka, northeastern Afghanistan, Nepal, and Bangladesh.

South Asia: Water surpluses to persist in Nepal, Bangladesh, Sri Lanka, deficits in India

While water surpluses may persist in northeastern Afghanistan, Nepal, Bangladesh, and Sri Lanka, the remainder of South Asia is expected to experience water deficits. Of particular interest are the widespread and exceptional water deficits forecast for much of India November 2015 through January 2016.

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.
