ISciences Worldwide Water Watch List April 2024

The forecast for April 2024 expects significant water deficits for the 12-month period of January 2024 through December 2024 in South America, northeastern Africa, and the Middle East. Areas expected to experience surplus include eastern to eastern Africa, northern Australia, Europe, and Southeast Asia.

The forecast indicates that exceptional deficits will persist in northwestern regions of China, but lessen in size in northern and northeastern China. Surpluses occurring in Tibet are also expected to remain but diminish in size.

The forecast indicates that deficits will persist throughout Mainland Southeast Asia, but decrease in intensity, becoming mostly moderate to severe anomalies. Intense surplus is expected to expand throughout Maritime Southeast Asia, particularly in central Indonesia, Papua, and Papua New Guinea.

South Asia: Surplus expands throughout India

The forecast indicates that most exceptional deficits in Pakistan and Afghanistan will dissipate, though some regions are expected to experience lingering deficits. India is expected to observe widespread surplus throughout the country.

Middle East: Intense deficits to persist on the Arabian Peninsula

Middle East: Intense deficits to persist on the Arabian Peninsula

The near-term forecast through November indicates a significant retreat of exceptional deficits on the Arabian Peninsula though deficits will continue to emerge, reaching south into much of Yemen and southern Oman. Deficits in the Levant will downgrade to moderate. Exceptional deficits in Iraq west of the Euphrates are expected to become slightly less intense except in the south. Deficits will emerge throughout much of the eastern two-thirds of Iran. After November exceptional deficits are forecast to nearly disappear though widespread deficits of lesser intensity will continue to emerge.

Middle East: Water deficits on the Arabian Peninsula will moderate after October

Middle East: Water deficits on the Arabian Peninsula will moderate after October

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. 

Middle East: Widespread intense deficits persist on the Arabian Peninsula

Middle East: Widespread intense deficits persist on the Arabian Peninsula

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.

Middle East: Exceptional water deficits forecast for the Arabian Peninsula

Middle East: Exceptional water deficits forecast for the Arabian Peninsula

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.

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.
