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.

Southeast Asia and the Pacific: Surplus spreads ...

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.

Liaodong Peninsula

East Asia: Water surpluses in Shanghai, deficits in Inner Mongolia

East Asia: Water surpluses in Shanghai, deficits in Inner Mongolia

Water conditions observed in the region through November and forecast through April are characterized by exceptional anomalies, both surpluses and deficits, while the forecast for the latter six months of the 12-month forecast (May through October) shows a decrease in the intensity of anomalies. From February through April surpluses are forecast from Shanghai through northern Hunan. Extreme to exceptional deficits are forecast for southern Mongolia, western Inner Mongolia (China), eastern Yunnan, and northern Taiwan. Moderate deficits are expected in Ningxia, southern Shaanxi, Gansu, eastern Sichuan, the Liaodong Peninsula, eastern Guangxi, and Guangdong. Both deficits and surpluses reaching exceptional intensity will continue to emerge in China’s western half.

East Asia: Water surpluses forecast in Shanghai; deficits eastern Sichuan

East Asia: Water surpluses forecast in Shanghai; deficits eastern Sichuan

Water surpluses are forecast to persist in Southeast China through March but with diminished severity, except in Shanghai and Jiangsu where exceptional surpluses may persist. Deficits will continue to emerge on the Liaodong Peninsula, eastern Sichuan, Shaanxi, Gansu, Ningxia, and eastern Yunnan. Exceptional deficits intermingled with conditions of both deficit and surplus are expected across northern China from central Inner Mongolia west and north into Mongolia. After March Southeast China is forecast to transition to normal conditions and anomalies elsewhere in the country will generally diminish in severity.

East Asia: Water surpluses from Jiangsu to Guangdong

East Asia: Water surpluses from Jiangsu to Guangdong

Water surpluses are forecast to persist through February in a vast area along China’s coast from Jiangsu south through Guangdong and in Hainan, including exceptional surpluses in Shanghai, Jiangsu, Anhui, Fujian, Guangdong, and southern Taiwan. Water deficits will persist through February on the Liaodong Peninsula and in northeast North Korea, and through May near Incheon, South Korea and in southern Shaanxi, eastern Sichuan, Guizhou, and Yunnan with exceptional severity in Yunnan.

ISciences Worldwide Water Watch List December 2016

Regions likely to have significant water deficits for the 12-month period from September 2016 through August 2017 include: the US South; Chile; Scandinavia; northern Africa, southern Somalia, and South Africa; the Middle East; southern India; Cambodia; and northern Russia. Water surpluses are forecast for: southern Minnesota, Nicaragua, Kazakhstan, Bangladesh, western Myanmar, Laos, Vietnam, and Jiangsu and Shanghai, China This watch list is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 6 December 2016.

East Asia: Water surpluses forecast to persist in Shanghai, Jiangsu; deficits near Seoul

East Asia: Water surpluses forecast to persist in Shanghai, Jiangsu; deficits near Seoul

Water deficits are forecast to diminish in severity November through January in Northeast China, the Korean Peninsula, and the Shandong Peninsula, but will continue to emerge on Liaodong Peninsula, Guizhou, northeast Guangxi, and eastern Yunnan. Exceptional surpluses will persist in Shanghai, Jiangsu, Anhui, and Fujian, but from February through April conditions in Fujian will transition to near-normal. Moderate deficits will emerge in many parts of North Korea. 

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.
