Southeast Asia & the Pacific: Water deficits forecast to spread in Malaysia, emerge in Indonesia

Southeast Asia & the Pacific: Water deficits forecast to spread in Malaysia, emerge in Indonesia

The forecast indicates a transition away from widespread, intense water surplus to deficit. Surpluses are forecast, however, for parts of Myanmar, northern Laos, northwestern Vietnam, eastern Cambodia, central Philippines, and East Nusa Tengara. Intense deficits will emerge in southernmost Thailand, and spread in Malaysia and northern Sumatra. Deficits of varying intensity are expected to emerge throughout Indonesia and may be extreme in West Nusa Tengara and Timor-Leste. Deficits in Papua New Guinea will downgrade but remain severe.

Southeast Asia & the Pacific: Water deficits forecast for the Malay Peninsula

Southeast Asia & the Pacific: Water deficits forecast for the Malay Peninsula

The forecast indicates a transition away from water surplus to deficit. Moderate deficits are forecast for northern Cambodia, southern Vietnam, northern Luzon, and pockets of Sumatra and Java. More intense deficits are forecast for peninsular Thailand and Malaysia, eastern Papua New Guinea, western Timor Leste, and West Nusa Tengara. Surpluses are expected in north-central Vietnam, northern Borneo, northern Sumatra, central Philippines, North Sulawesi, East Nusa Tengara, and Pulau Sumba.

Southeast Asia & the Pacific: Exceptional deficits forecast for Peninsular Malaysia

Southeast Asia & the Pacific: Exceptional deficits forecast for Peninsular Malaysia

The forecast indicates a transition away from water surplus to deficit. Deficits are forecast for mainland Southeast Asia, Peninsular Malaysia, northern Sumatra, and Luzon and Mindanao in the Philippines; deficits may be exceptional in Peninsular Malaysia. Exceptional deficits in Cambodia will shrink considerably but persist in a pocket northeast of Tonlé Sap. Severe deficits are forecast for Vietnam’s Mekong Delta region. Surpluses are forecast for central Philippines. After June, anomalies in the region will downgrade though severe deficits will continue in Peninsular Malaysia.

Southeast Asia & the Pacific: Water surplus forecast for Myanmar, Vietnam, Philippines

Southeast Asia & the Pacific: Water surplus forecast for Myanmar, Vietnam, Philippines

Cambodia continues to stand out through May in Southeast Asia with exceptional water deficit in the west. Surpluses are forecast for much of the rest of Southeast Asia, the Philippines, and Malaysia, and may be especially intense in western Myanmar, around the Gulf of Tonkin, central Philippines, and Brunei. Deficits will emerge in the southern tip of Sumatra and into Java, but are expected to nearly disappear in Papua New Guinea, persisting mainly around the Gulf of Papua. After May, surpluses in the region will retreat and Cambodia will return to near-normal conditions.

Southeast Asia & the Pacific: Water deficits in Cambodia to abate after April

Southeast Asia & the Pacific: Water deficits in Cambodia to abate after April

Exceptional water deficits will persist in western Cambodia through April. Deficits of varying severity are expected in Sumatra, Java, western Borneo, and Papua New Guinea. Intense surpluses are forecast for western and eastern Myanmar, northern Laos, along the Mekong River until it reaches Cambodia, and central Philippines. Surpluses are also forecast for Vietnam, pockets of Thailand, Brunei, and northeastern Borneo. After April, surpluses will retreat, Cambodia will transition to near-normal, and deficits are expected in Malaysia, Sumatra, and western Borneo. 

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.
