The forecast through May indicates that water deficits will downgrade, with moderate anomalies throughout most of the continent, some pockets of greater intensity, and surpluses in Tanzania. Exceptional deficits are forecast in the Ethiopian Highlands. Other areas of significant deficit include Equatorial Guinea, Lesotho, Guinea-Bissau, central Republic of the Congo, eastern Angola, western Zambia and central Zambia and along the Zambezi River, and northern Zimbabwe.
The forecast through May indicates that water deficits in Brazil will shrink and downgrade significantly, though intense deficits are forecast for eastern Minas Gerais, Espíritu Santo, and São Paulo. Surpluses will emerge in northeastern states and will moderate but increase in the south. Exceptional deficits are forecast for Suriname and French Guiana, and deficits of varying intensity for Brazil’s northern neighbors, and Peru, Chile, eastern Bolivia, and Argentina. Surpluses will shrink in northern Bolivia, downgrade in central Paraguay, and moderate in northeastern Argentina and Uruguay.
Most notable in the forecast through May is the absence of widespread, intense water surpluses observed in the East in prior months and the emergence of surpluses in the West. Surpluses will shrink and downgrade in the center of the country but remain widespread in a broad path from southern Minnesota to the Gulf of Mexico and will be intense in Kansas. Moderate surpluses will cover much of California, and many Rocky Mountain States will transition from deficit to surplus.
The forecast through May indicates that the widespread, exceptional water deficits that have dominated Australia in prior months will diminish considerably. However, exceptional deficits are forecast in the far north and in northern South Australia. Severe deficits are forecast in eastern Queensland and extreme anomalies in the Northern Tableland of New South Wales. Intense deficits are also forecast for Tasmania, New Zealand, and New Caledonia.
Regions forecast to have significant water deficits for the 12-month period from December 2018 through November 2019 include: French Guiana, Finland, Latvia, Angola, Namibia, United Arab Emirates, Cambodia, and Australia. Areas with a forecast of significant water surplus include: Kansas, Texas, and Tennessee (US), Syria, Tanzania, and China. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 7 March 2019.
ISciences announced today the start of the Data ANalytics and Tools for Ecosecurity (DANTE) project. A joint effort of ISciences, the Center for International Earth Science Information Network (CIESIN) and North Carolina-based CASE Consultants International, DANTE aims to provide scientists, defense and security analysts, relief agencies, businesses and communities with enhanced insights into the connections between environmental stresses and security outcomes.
The March Outlook indicates exceptionally warmer than normal temperatures from eastern Mongolia through Northeast China, the Korean Peninsula, and Japan. Conditions are expected to be drier than normal in Northeast China as well.
The forecast through April indicates that water surpluses in the Ob River Basin of Russia will downgrade somewhat. Exceptional surpluses are expected in the northern Yenisei River watershed. Surpluses will increase in the Northern European Plain from the Kola Peninsula in the west past the Vychegda Lowland. Deficits are forecast for the Upper Volga River Basin and Trans Volga region of Russia, western Kazakhstan, and eastern Tajikistan. Deficits will be severe in the Upper Volga Basin.
The forecast through April indicates a vast stretch of intense water deficits in southern and eastern Mongolia and into Inner Mongolia, China. Moderate surpluses will emerge on the Lower Reaches of the Yellow River. Widespread surpluses will persist in the Yangtze Basin’s Lower Reaches and in the southern portion of the Middle Reaches, reaching into Guangxi. Surpluses will be exceptional in Shanghai and Jiangsu. Deficits are forecast for North Korea and northern Honshu, Japan. Some surpluses are forecast for South Korea and Kyushu, Japan.
The forecast through April indicates that, while exceptional water deficits in Gujarat and in the south will downgrade, widespread deficits of varying intensity are forecast in western and southern India. Surpluses will re-emerge in Uttar Pradesh in the western Gangetic Plain. Other regions with surpluses include Mizoram (India), Bangladesh, Nepal, rivers in northern Pakistan, and around Kabul, Afghanistan.
