ISciences Worldwide Water Watch List March 2018

ISciences Worldwide Water Watch List March 2018

Regions forecast to have significant water deficits for the 12-month period from December 2017 through November 2018 include: the US West, Southwest, and South Atlantic States; southern Venezuela; Uruguay; northeastern Argentina; Finland; northern Africa and Gabon; and southern Iraq. Areas with a forecast of significant water surplus include: the Ohio River Valley and western Montana (US); Paraguay; Tanzania and Ethiopia; Ireland; Central and Eastern Europe; and European Russia. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 7 March 2018.

South America: Water deficits forecast to diminish in eastern Brazil

South America: Water deficits forecast to diminish in eastern Brazil

Exceptional water deficits are forecast to diminish considerably in the coming months, but pockets are forecast through April in southern Venezuela, Amapá (Brazil), western Brazil, western Ecuador, and around the Gulf of Corcovado in southern Chile. Deficits are also forecast in southern Colombia, northern Peru, Uruguay, Rio Grande do Sul (Brazil), and northeastern Argentina. Surplus is forecast in northeastern Venezuela, scattered throughout eastern Brazil, northern Bolivia, and eastern Paraguay. After April, the extent of anomalous water conditions will shrink. 

South America: Much wetter than normal conditions forecast for Paraguay

South America: Much wetter than normal conditions forecast for Paraguay

A number of significant transitions are forecast for the next three months. Though exceptional water deficits will diminish across northern South America – transitioning to surplus in many northern nations and the northern Amazon Basin – deficits will intensify in eastern Brazil. Surpluses are forecast to emerge throughout Paraguay and into southern Brazil. Surpluses in Uruguay will transition to moderate deficit; Buenos Aires Province, Argentina will transition from surplus to near-normal. After March, water anomalies will moderate considerably across most of the continent. 

South America: Intense water deficits to emerge in Rio Grande do Norte, Paraiba, Pernambuco

South America: Intense water deficits to emerge in Rio Grande do Norte, Paraiba, Pernambuco

Exceptional water deficits are forecast to diminish considerably over the next three months except in the western Amazon Basin in Brazil and Acre, Rondônia, Mato Grosso, and Tocantins. Deficits are also expected across Brazil’s Northeast region. Elsewhere on the continent, intense deficits are expected in western Bolivia and the Gulf of Corcovado, Chile. Areas of surpluses include central Colombia; Mato Grosso do Sul, Brazil; and La Pampa Province, Argentina. After February widespread surpluses will emerge in the northern Amazon Basin and Venezuela, Guyana, and Suriname.

South America: Exceptional water deficits in Brazil forecast to retreat to the north after September

South America: Exceptional water deficits in Brazil forecast to retreat to the north after September

Recently observed conditions across the whole of South America are expected to persist through September with a slight decrease in the extent of exceptional water deficits in much of Brazil north of Rio de Janeiro. Surpluses in eastern Paraguay and southern Brazil should transition to near-normal conditions during this period, but exceptional surpluses are expected to persist in La Pampa and Buenos Aires Provinces in Argentina. After September conditions are forecast to improve across the continent though exceptional water deficits will persist in Amapá and northern Pará, Brazil and in nearby northern regions.

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.
