Southeast Asia & the Pacific: Water surpluses through April, deficits after

Southeast Asia & the Pacific: Water surpluses through April, deficits after

The forecast through April indicates the beginning of a transition from water surplus to deficit, after which deficits of varying intensity will prevail. Through April surpluses are forecast for Vietnam, the Malay Peninsula, the Philippines, and North Sumatra, Indonesia. Exceptional deficits will persist in Cambodia, while Thailand can expect deficits in the north and surpluses in the south. Java is expected to transition from surplus to deficit. Deficits will emerge in central Borneo and will persist in Papua New Guinea. After April deficits are forecast for most of the region, and may be more severe and widespread in Malaysia, Indonesia, and Papua New Guinea.

South Asia: Water deficits continue to emerge in India, surpluses in NE Afghanistan

South Asia: Water deficits continue to emerge in India, surpluses in NE 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.

Australia & New Zealand: Water deficits in Queensland & North Island

Australia & New Zealand: Water deficits in Queensland & North Island

From February through April moderate to exceptional deficits are forecast for much of Queensland. Primarily moderate deficits are forecast for New South Wales and southern Victoria. Moderate to severe deficits are expected to persist in North Island, New Zealand. Surpluses in the northern part of Western Australia and into the Victoria River Basin of Northern Territory are expected to diminish in severity. The forecast after April looks less eventful with moderate deficits tracing a path from Northern Territory’s Top End down along the eastern coast through New South Wales.

Africa: Exceptional water deficits recede but widespread deficits persist

Africa: Exceptional water deficits recede but widespread deficits persist

The extent of exceptional deficits across the continent will diminish through April, but moderate to extreme deficits will persist across northern Africa and across Africa’s mid-section from Gabon to southern Somalia. Deficits will diminish considerably in Madagascar though persist in the south. Surpluses are forecast in the Okavango Delta in northern Botswana, southern Zambia, Zimbabwe, and western Mozambique. The forecast for May through July indicates a downgrade in the intensity of deficits in the southern Sahel and an increase in the intensity of deficits across northern Africa where extreme to exceptional deficits are expected to emerge in eastern Algeria, northern Niger, Libya, Egypt, and northern Sudan.

ISciences Worldwide Water Watch List February 2017

Regions likely to have significant water deficits for the 12-month period from November 2016 through October 2017 include: Arkansas, Quebec, French Guiana, Chile, Brazil, France, Germany, Finland, Estonia, Latvia, northern Africa, Kenya, Tanzania, Yemen, Saudi Arabia, United Arab Emirates, Arctic Russia, southern India, Cambodia, Papua New Guinea, Inner Mongolia, and Queensland. Water surpluses are forecast for: Idaho, Nevada, California, northern Botswana, northeastern Afghanistan, central Vietnam, southern Thailand, and Shanghai. This Watch List is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 8 February 2017.

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.
