Laos has notified its Southeast Asian neighbours that it's moving ahead with a third contentious hydro dam on the Mekong River's mainstream.
The Mekong River Commission, an organisation that groups Laos, Cambodia, Vietnam and Thailand for joint management of the river, said in a statement it has received notice from Laos that it will undertake a process of consultation about the Pak Beng dam.
In the previous consultation cases for the Xayaburi and Don Sahong dams, Laos pressed forward with the projects despite vociferous objections from the other countries, scientists and conservationists. It has already begun preparatory work for the 912-megawatt Pak Beng dam in the northern province of Oudomxay.
Critics of the dams say they will damage wild fisheries and a rice bowl delta that support 60 million people in the region. The river basin is already under pressure from dozens of dams already built on Mekong tributaries.
The commission's relevance as a transboundary organisation has been undermined by Laos, as well as its own internal failings. Foreign donors have cut financial assistance and the commission's staff numbers have been slashed.
But it said in the statement that despite the lack of agreement, the consultation process for the Xayaburi dam had resulted in the Lao government and the project's Thai developer spending an additional $400 million on design changes that could mitigate some of its damaging effects.
The government of Communist Party-ruled Laos sees hydro-electricity exports as a way to develop its impoverished economy and plans up to nine dams on the Mekong mainstream.
But by jeopardising wild fisheries, it might add to its own food security problems. The World Food Program says nearly half of children under the age of five in Laos suffer from chronic malnutrition and stunting.
