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.
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.
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.
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.
Warmer than normal temperatures are indicated in the January Outlook for much of Europe, particularly Eastern Europe and European Russia. Wetter than normal conditions are expected in South America's northernmost nations and in Myanmar.
The extent of exceptional water deficits will diminish considerably through February in Southern Europe leaving primarily moderate deficits on the Iberian Peninsula, France, and Italy, with more intense deficits in southeastern France. Exceptional surpluses will continue to emerge in western European Russia and Poland and will emerge in Belarus. Surpluses of varying severity will emerge in greater extent in Central and Eastern Europe. After February the extent and intensity of surpluses in Russia, Central, and Eastern Europe will diminish but surpluses will remain intense in central Poland.
Widespread exceptional deficits observed in the prior three months are expected to moderate considerably through February, though extreme deficits are in the forecast for Lebanon and Israel. Deficits of slightly lesser intensity, but still severe, are forecast for southeastern Turkey, Syria, pockets throughout Iraq, central Iran, northern Saudi Arabia, and southwestern Yemen. Primarily moderate deficits are forecast nearly everywhere else. After February, deficits on the Arabian Peninsula are expected to ratchet up in intensity, and moderate deficits will continue to emerge in Turkey.
The near-term forecast indicates continued improvement in water conditions in southern Africa as exceptional deficits nearly disappear. Intense deficits are, however, expected in Lesotho. Deficits are forecast across northern Africa including pockets of exceptional deficit in western Mauritania through Guinea-Bissau, scattered around the Gulf of Guinea, small pockets across the southern Sahara, and in southeastern Ethiopia. Surpluses are expected in southern Sudan, South Sudan, western Ethiopia, Kenya, Tanzania, western DRC, and western CAR into Cameroon. After February intense deficits will emerge in the north.
Through May 2018 intense water deficits are forecast in central India and intense water surpluses in Bangladesh. In the near-term through February, deficits are forecast throughout most of India with exceptional deficits expected in eastern Gujarat and Karnataka. Exceptional surpluses are expected in West Bengal, Tripura, Mizoram, eastern Jammu and Kashmir, and the Pennar River Basin in southern India. Moderate deficits are forecast for Pakistan and Afghanistan with some pockets of exceptional deficit in the northeast. Surpluses are forecast for western Bhutan and much of Nepal.
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.
