Merry-go-round on the Mekong - new dam looms as failed dam faces closure

WWF 3 Mar 11;

Bangkok, Thailand: Investors in proposed Mekong River dams need to absorb the lessons of the Mun River dam, a notable economic failure as well as the cause of massive environmental and social disruption, WWF warned today.

Thailand’s government is considering a plan to permanently open the gates on the Mun River dam in hopes of restoring the river basin ecosystem and reviving livelihoods along one of the country’s primary Mekong tributaries. Since its over-budget construction in the early 1990s, the Mun River dam has decimated the fish population, displaced communities and failed to deliver profit for investors.

Similar risks may accompany the proposed Xayaburi dam, slated for construction on the Mekong River mainstream in northern Laos, because of critical gaps in the understanding of fisheries, biodiversity and sediment movement on Asia’s most biodiverse river.

At stake, according to WWF, are the livelihoods of tens of millions of people in the region.

“The Mekong is a unique and particularly complex ecosystem that hosts the most productive inland fisheries in the world and is second only to the Amazon in number of fish species,” said Dr. Suphasuk Pradubsuk, National Policy Coordinator with WWF-Thailand.

“The lessons of Thailand’s Mun River dam are still fresh: Hasty environmental and social impact studies can lead to a bitter lose-lose situation for both fishermen and dam owners.”

At $233 million, the Mun River dam cost investors twice the original estimate, and energy production fell to a third of expected capacity during the dry season. Return on investment dropped from a projected 12 per cent to 5 per cent.

Stakes high for investors

“All promoters of hydropower in the Mekong must learn the lessons of the Mun River dam,” said Suphasuk. “Current limited baseline studies do not sufficiently explain how the different parts of the ecosystem interact, so we can’t accurately predict the effects of any mainstream dam.”

“The stakes are very high for people and nature, and therefore for investors as well.”

The Xayaburi dam in Laos, the first to be proposed on the lower Mekong mainstream, is just ending the “consultation” phase stipulated under the procedures of the Mekong River Commission (MRC). This is meant to ensure a rigorous and transparent scientific assessment of the impact of the dam.

A number of Thai banks, including Bangkok Bank, Kasikorn Bank, Krung Thai Bank and Siam Commercial Bank, are planning to support the Thai developer CH Karnchang PCL on the Xayaburi project.

“From an investor standpoint, this project is risky, plain and simple,” says.Suphasuk. “Developers and investors should consider the reputational risk of damming Asia’s most biodiverse river.”

“Only the Kasikorn Bank has had discussions with WWF about the risks of the project, while the Bangkok, Krung Thai and Siam Commercial banks have not responded to WWF’s requests to meet.

“The banks could only benefit from discussing the risks before making such an important decision for the people and ecosystem of the Mekong River, as well as for their own profit and corporate image.”

Study indicates lessons not learned

The just-released Xayaburi feasibility study gives no indication that any of the Mun River dam lessons have been learned, WWF noted.

“The study blandly assures us that impacts of the Xayaburi dam would be low level, without providing anything much to justify this optimism,” said Phansiri Winichagoon, WWF-Thailand Country Director. “Dam proponents were equally bland about impacts on the Mun River too, but there was economic and environmental disaster lurking in what was ignored and what was only superficially considered.

“This study falls a long way short of current best practice in environmental assessment.”

WWF supports a 10-year delay in the approval of all lower Mekong mainstream dams to ensure a comprehensive understanding of all the impacts of their construction and operation.

Alternatively, WWF and partners promote using assessment tools to assist decision making for more sustainable hydropower projects which could have much less impact on fish migration or sediment movement.

Mekong dam faces resistance
UPI 3 Mar 11;

BANGKOK, March 3 (UPI) -- A 1,260-megawatt hydropower project in northern Laos poses a threat to the environment and surrounding communities, environmentalists say.

Xayaburi dam, the first of 11 hydropower dams proposed along the lower Mekong River, is just ending the consultation phase and a decision on construction could come as early as this month.

The Mekong Agreement, which recognizes the shared impacts of river development projects on neighboring countries, stipulates that Thailand, Cambodia, Laos and Vietnam must all approve major projects on the lower Mekong River.

Last June, Thai electricity utility EGAT signed an initial agreement with the dam's main developer, Thai construction company Ch Karnchang, to purchase more than 95 percent of the project's electricity.

Potential investors for the $3.5 billion hydropower project include Bangkok Bank, Kasikorn Bank, Krung Thai Bank and Siam Commercial Bank.

But investors for Xayaburi, as well as the 11 other proposed Mekong River projects, need to absorb the lessons of Thailand's Mun River dam, WWF said Thursday. That project, constructed in the early 1990s, was a "notable economic failure" which caused massive environmental and social disruption, the environmental group said.

Mun River's final cost was $233 million, double the original estimate, with return on investment falling to 5 percent from a projected return of 12 percent, WWF said.

"From an investor standpoint, this project is risky, plain and simple," said Suphasuk Pradubsuk, national policy coordinator with WWF-Thailand, in a release.

"Developers and investors should consider the reputational risk of damming Asia's most bio-diverse river."

The Mekong, he said, is a "unique and particularly complex" ecosystem, hosting the most productive inland fisheries in the world, second only to the Amazon in the number of fish species.

Environmental group International Rivers says that more than 200,000 fishermen and farmers -- most of the lower riverside community -- would suffer displacement and reduced earnings because of the Xayaburi project.

"Millions more people in the region are likely to be adversely (affected) through changes to the river's biodiversity, fisheries and sediment flows," said Ame Trandem of International Rivers, reports IRIN, the news service of the U.N. Office for the Coordination of Humanitarian Affairs.

The Laotian government, however, maintains that Xayaburi won't have any significant impact on the Mekong mainstream.

International Rivers has called for better energy solutions to protect the Mekong River.

"What happens with the Xayaburi Dam will essentially set the precedent for whether more mainstream dams are built or not," Trandem said.
