The forecast through June indicates that widespread water surpluses will persist from northern Syria into southern Turkey, from the Euphrates River in Iraq well into western Iran, and in northern Iran along the coast. Deficits will downgrade on the Arabian Peninsula but will remain widespread. Central and northern Turkey will transition from surplus to moderate deficit.

Water deficits are expected to shrink and downgrade significantly through December but intense deficits will persist in southern Iraq. Severe deficits are forecast for Georgia, Kuwait, most of Saudi Arabia, and into western United Arab Emirates. Deficits of varying severity are expected in Yemen, moderate to severe deficits in central and southern Iran, and mild deficits in the Levant.
Exceptional water deficits are forecast to shrink, though deficits in the region will increase overall, emerging in Turkey, Yemen, and Oman. Exceptional deficits are expected in southern Iraq. Deficits will remain widespread in the bulk of Iran east of Tehran, with extreme conditions in southern Kerman Province. After May, deficits will emerge in eastern Turkey, joining those in the rest of the country, and moderate deficits will emerge throughout Armenia, Georgia, and Azerbaijan.
Exceptional water deficits are forecast to nearly disappear in the near-term leaving primarily moderate to severe deficits across the region. Severe deficits are forecast November through January along stretches of the Euphrates River, and deficits of greater intensity are expected along Turkey’s northern coast and in southwestern and southeastern Yemen. Overall, water deficits will diminish slightly in extent and intensity from February through April.
Exceptional water deficits in the Middle East are forecast to nearly disappear after October though widespread deficits of lesser intensity will continue to emerge. Until then, however, extreme to exceptional deficits will blanket much of the Arabian Peninsula, Syria, Jordan, Iraq west of the Euphrates, much of Georgia, and a pocket of southwestern Turkey surrounding Antalya. After October significant deficits remain in the forecast for Georgia, northern Saudi Arabia, Iraq west of the Euphrates, pockets of central Iran, and southwestern and eastern Yemen.
Widespread intense water deficits are forecast for the Arabian Peninsula through September, gradually diminishing in extent and severity thereafter. From July through September exceptional deficits will persist across central Saudi Arabia, in southern Iraq, and in Lebanon, and severe to extreme deficits are forecast for Qatar, United Arab Emirates, Yemen, Iraq west of the Euphrates, and North Khorasan, Iran. Surpluses in Fars and near Tehran, Iran will transition to conditions of both deficit and surplus, receding by early next year. Surpluses along the northern Iran/Iraq border will persist through December, and a pocket of exceptional surplus in central Oman will persist through March 2018.
Regions forecast to have significant water deficits for the 12-month period from April 2017 through March 2018 include: Brazil, Europe, northern Africa, Gabon, Somalia, Saudi Arabia, Cambodia, South Korea, Tasmania, and Mongolia. Water surpluses are forecast for: the US Gulf Coast and Idaho, La Pampa (Argentina), western European Russia, eastern Romania, southeastern Tanzania, the Volga River Basin, between the Upper Ob and the Tom Rivers (Russia), Kazakhstan, Bangladesh, and the southern Yangtze River Basin. This Watch List is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 10 July 2017.
Exceptional water deficits spanning the Arabian Peninsula are expected to continue through November affecting southern Iraq, Kuwait, Saudi Arabia, the Gulf States, all of Yemen, and most of Oman. Conditions are expected to moderate in early 2018. Moderate to exceptional surpluses in northern Iraq extending into Iran should subside by December. Exceptional surpluses in south central Iran are expected to persist through the forecast period before moderating between December and February 2018. A pocket of exceptional surplus in central Oman persists throughout the forecast period into 2018.
