South Asia: Deficits remain in Afghanistan, ...

Exceptional surpluses in India will mostly dissipate, transitioning to moderate to severe surpluses. Exceptional deficits will remain in Afghanistan and Pakistan. 

South Asia: Deficits remain in Afghanistan, Pakistan, surpluses persist in India

Africa: Water deficits recede in Somalia & Southern Africa

Africa: Water deficits recede in Somalia & Southern Africa

Most areas of exceptional water deficit will downgrade through March. Moderate deficits are expected across northern Africa, with more severe conditions in Morocco, Western Sahara, and Guinea-Bissau. Intense deficits are also forecast for southeastern Nigeria, southwestern Cameroon, Equatorial Guinea, and Gabon. Intense deficits will retreat in southern Africa. Surpluses will linger in southern Sudan, northeastern South Sudan, Tanzania, northern Mozambique, and northern Madagascar. After March deficits in northern Africa will intensify, but south of the Sahara milder conditions will prevail.

Southeast Asia & the Pacific: Intense water deficits persist in Cambodia

Southeast Asia & the Pacific: Intense water deficits persist in Cambodia

Though water deficits persist in western Cambodia and Papua New Guinea, surpluses have dominated the rest of the region but will gradually transition to moderate deficit. Through March, exceptional surpluses are forecast in Myanmar, northern Laos, and northern Vietnam; less intense surpluses in southern Laos, eastern Cambodia, southern Vietnam, the Philippines, and Sumatra; and exceptional deficits in western Cambodia and northern Papua New Guinea. Mild deficits will emerge in Indonesia, and continue to emerge overall after March. 

South Asia: Intense water deficits Madhya Pradesh, Karnataka, eastern Gujarat

South Asia: Intense water deficits Madhya Pradesh, Karnataka, eastern Gujarat

Intense water deficits are forecast to persist in Madhya Pradesh, India through June 2018. Through March, deficits will spread throughout much of India. Intense deficits will persist in Madhya Pradesh and Karnataka, and will emerge in eastern Gujarat. Deficits will be moderate in southern Pakistan but more severe in Afghanistan. Exceptional surpluses will continue in Bangladesh and nearby states in India. After March, water anomalies will downgrade overall, but deficits will persist in Madhya Pradesh and will emerge in India’s far northeast, and surpluses will re-emerge in the Pennar River Basin. 

Europe: Water surplus to persist in Ireland, Central Europe, & European Russia

Europe: Water surplus to persist in Ireland, Central Europe, & European Russia

The forecast indicates a transition in April to water deficits across much of Europe, but until then widespread surpluses will persist in Northern, Central, Eastern Europe, and European Russia and are expected to be exceptional in Russia, northern Poland, northwestern Ireland, and along the Dnieper River in Ukraine. Deficits will continue to emerge in Southern Europe, particularly the Iberian Peninsula, but will retreat significantly in France, persisting only along the southern coast. Intense deficits will emerge in Crimea, and will persist in northern Finland and northern Norway.

ISciences Worldwide Water Watch List January 2018

Regions forecast to have significant water deficits for the 12-month period from October 2017 through September 2018 include: Missouri (US), Brazil, Spain, Portugal, Morocco, Turkmenistan, Inner Mongolia (China), and South Australia and Tasmania (Australia). Areas with a forecast of significant water surplus include: Ireland, Poland, and Bangladesh. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 10 January 2018.

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.
