Current Water Anomalies: Brazil

It is widely known that Brazil is in the midst of a crippling drought.  The map is based on 3 months of observed data (Dec14-Feb15) and nine months of forecast data (Mar15-Nov15).  It shows that the drought is likely to continue through November.  This will severely stress the ability of Sao Paulo to provide water to its citizens where water is already rationed, and continue to restrict the ability of Brazil to produce hydropower requiring significant expenditures for backup generation from natural gas and oil.

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.
