Exceptional surpluses will persist in northern regions of Mainland Southeast Asia. Most areas of Maritime Southeast Asia will observe near-normal conditions.
Severe to exceptional surpluses are expected to persist in several regions of India and emerge in Bangladesh. Some South Asian countries will observe isolated pockets of deficit.
Exceptional deficit anomalies will continue in southern regions of the Middle East, as well as in coastal regions of Turkey. Isolated pockets of exceptional deficit will also persist in Iran. Southwestern coastal areas of the Middle East will continue to observe moderate to severe surplus.
Exceptional deficits will remain in areas near Lake Baikal and in much of western Russia. Northern and southeastern Kazakhstan will observe continuing surpluses of varying intensity, as will some Russian areas near the Lena River.
Regions forecast to have significant water deficits for the 12-month period of June 2021 through May 2022 include: the U.S. West, Canada, North Africa, Central Asia, and Hokkaido, Japan. Areas with a forecast of significant water surplus include: Northeast China, the Yellow River, Yangtze River, Nepal, Bangladesh, and the Yenisei River. This Watch List is based on ISciences Water Security Indicator Model v2 (WSIMv2) run on 7 September 2021.
Severe to exceptional water deficits are forecast to emerge April through June across central and southern India. Deficits will also emerge near Karachi, Pakistan and will continue to emerge in western Pakistan. Surpluses are forecast in Jammu and Kashmir, eastern Afghanistan, and along the northern Indus River in Pakistan. From July through September deficits in India will decrease in intensity but increase in extent as deficits emerge in the Chambal River watershed. Severe to extreme deficits will persist in Madhya Pradesh. Moderate to severe deficits are also forecast to emerge throughout Bangladesh.
Regions likely to have significant water deficits for the 12-month period from January 2017 through December 2017 include: Arkansas and Florida (US), Quebec (Canada), Brazil, Finland, Estonia, Denmark, Libya, Egypt, Saudi Arabia, Yemen, Tamil Nadu (India), Borneo, and New Guinea. Water surpluses are forecast for: Idaho and the Pacific Northwest (US), southwestern Zambia, the Okavango Delta (Botswana), northeastern Pakistan, between the Irtysh and Tom Rivers (Russia), central Vietnam, and eastern Queensland (Australia). This Watch List is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 7 April 2017.
The March through May forecast indicates some relief from water deficit conditions for many parts of India. However, severe to extreme deficits are forecast to persist in Gujarat and moderate deficits are forecast in Uttarakhand, southern India, and Sri Lanka. Surpluses ranging from moderate to exceptional are forecast for the eastern Ganges Basin, the eastern two-thirds of Nepal, and Bangladesh. Surpluses are also expected along the northern tributaries of the Indus River in Pakistan and in eastern Afghanistan.
Though the extent of exceptional deficits in southern India is forecast to diminish February through April, deficits will emerge across the country’s mid-section in places which, in the prior three months, had seen normal or surplus water conditions. Exceptional deficits are forecast for Gujarat and northeast India; and in Karachi, Pakistan. Surpluses are forecast along major rivers in northeastern Pakistan, throughout Afghanistan, and in eastern Nepal. From May through July deficits in India will diminish considerably in severity except in Assam and Arunachal Pradesh. Surpluses will continue to emerge in Afghanistan and may be exceptional in the Upper Helmand Basin.
