VIETNAM RIVERS NETWORK (VRN) –Rivers and water resources are among the most valuable assets to humanity that need to be protected.

“It will be a major threat to Vietnam’s Mekong River delta,” said Dr. Pham Bich San, Deputy Secretary General of the Vietnam Union of Science and Technology Associations (VUSTA), adding that the dams on the Mekong mainstream will have negative impacts on the ecological environment, especially the lower course.

San cited recent research which found that the Mekong is one of the five biggest river basins in the world which has seen its current reduced the most sharply. The average annual flow in the lower course has declined by 10 percent over the last 30 years.

The Mekong section which runs across Vientiane in Laos has been so depleted in the last 10 years that people can wade across the river in the dry season.

In Thailand, the Chao Praya River, as it’s known by locals, which has traditionally been mild, unexpectedly caused major floods which lasted many months in 2011.

In the Mekong River Delta in Vietnam, salt water has encroached on the Tan Chau area in An Giang Province. This never happened in the past.

The Mekong River has always played a very important role in Vietnamese socio-economic development and regional food security. The Mekong River delta is home to 20 million people who are responsible for 27 percent of Vietnam’s GDP, 90 percent of rice exports and 60 percent of Vietnam’s seafood exports.

“VUSTA has many times in the past voiced its concern about the negative impacts of hydropower dams on Vietnam. Nevertheless, Laos went ahead and built its Xayabury hydropower plant. Now Vietnam needs to have a stronger voice over the Lao Dong Sahong project,” San said.

Professor Dr. Ho Uy Liem, a renowned scientist, some years ago warned that if Xayabury dam was built, it would create a very dangerous precedent for another 11 dams to be set up on the Mekong main stream.

“If so, this will be the destruction of the river,” Liem said. “This will deprive the livelihood of the 60 million people living along the riverside, especially the Vietnamese in the Mekong River Delta,” he said.

And Liem’s warning seems to turn into reality.

Le Bo Linh, Deputy Chair of the National Assembly’s Science & Technology Committee, has also expressed his deep concerns about the Lao decision to build Don Sahong dam, affirming that the work will affect the river’s hydrological regime, causing depletion in the dry season and bringing salinity to Vietnam’s Mekong River delta.

According to Linh, at the international meeting of the Mekong River Commission in April in HCM City, the involved parties approved a declaration which says that countries need to consult with others in the region if they plan to execute construction works on the Mekong main stream.

The Lao government, which promised at the meeting that it would consult with other countries, still has decided to set up its hydropower dams.

Linh said the government of Vietnam needs to express its official viewpoint on Laos building dams on the Mekong River, because it seems that concerns voiced by scientists and environmentalists, institutions and individuals are not enough for the Lao government to rethink the project.

    Mekong Matters: Workshop and Network for Development Journalists

    The rapid pace of development leading up to the the ASEAN Economic Community (AEC) is creating opportunities for journalists to find innovative and important environmental, business, investment, health and culture stories. Are you a Mekong-area journalist who reports on social and environmental impacts of development projects such as dams, mines, roads, ports or economic land concessions? Mekong Partnership for the Environment (MPE) may have workshop, fellowship, resource and networking opportunities for you.

    STOP DON SAHONG DAM, ELEVATE MEKONG COOPERATION

    Hanoi, VietNam –  A recent press release by International Rivers on 18/06/2014 has confirmed that the construction towards the controversial Don Sahong Dam in Southern Laos has continued despite growing opposition from neighboring governments and ongoing calls for regional consultation. The Don Sahong Dam, which is located on the Mekong mainstream, must undergo the Procedures for Notification, Prior Consultation and Agreement (PNPCA) as required by the 1995 Mekong Agreement. Nevertheless, the Lao government argues that Don Sahong Dam would not have to go through the PNPCA since it is not located on the mainstream. Laos continues to move forward unilaterally with this project despite opposition from regional communities and the governments of Cambodia, Thailand, and Vietnam.

    2nd VRN’s letter to Kasikorn Bank, Siam Commercial Bank and Bangkok Bank: Careful consideration and suspension of the loan to the Xayaburi hydropower dam project.

    The Xayaburi project is the first dam under construction, among 11 dams proposed on the lower Mekong mainstream. Many studies have already highlighted that the dams will cause severe impacts to the fish migration in Mekong River. Moreover, the dam will block sediment flow along the Mekong mainstream. The sediment prevents the Mekong Delta sinking and shrinking, and is the main source for the fertile delta land of Vietnam, which is known as the world’s rice basket. By unilaterally pushing forward with the project, Lao PDR has violated the 1995 Mekong Agreement signed by Cambodia, Lao PDR, Thailand and Viet Nam. Thus the project has been designed, and constructed started, without complying with the Mekong River Commission’s Procedure of Notification, Prior Consultation and Agreement (PNPCA), which is mandatory for all mainstream projects on the lower Mekong River.
