Dear Gen. Chavalit Yongchaiyudh,

We, the undersigned 76 organizations from 25 countries, are deeply concerned about the potential impacts of the Lancang-Mekong Navigation Channel Improvement Project and are concerned that the project is proceeding without a thorough and careful examination of its impacts on the environment and people's livelihoods.

As you are well aware, the Mekong River is a complex and rich ecosystem upon which millions of people depend for their livelihoods. Many have adapted to the river's ebbs and flows relying on the river's diverse and vibrant fisheries, cultivating vegetables on the riverbanks and using the river for transport and drinking water. However, this delicate balance is in jeopardy due to blasting and dredging for the Lancang-Mekong Navigation

Channel Improvement Project.

Poor environmental impact assessment, local opposition

Despite its potentially far-reaching impacts, the navigation project is proceeding without a comprehensive investigation of the project's social and environmental impacts. A recent article in the Cambodian Daily stated that the environmental impact assessment was “not up to international standards.” The project also fails to meet Thai legal standards on environmental impact studies and public participation, in violation of the agreement between China, Burma, Laos and Thailand. Villagers from Chiang Khong, Thailand, have expressed concerns about the project's potential impacts. Senators from Thailand have also voiced reservations and called for serious and careful study of the project's environmental impacts.

Destruction of rapids, reefs and shoals

The most serious impact of the project is the blasting and clearance of many rapids, shoals and scattered reefs to facilitate navigation. The destruction and blasting will have wide-ranging ecological impacts on countries located along the entire length of the Mekong. Rapids and reefs comprise some of the most productive riverine habitats, serving as vital breeding grounds and safe haven for fish and other forms of aquatic life, including plants such as Mekong seaweed (kai). Blasting the rapids and reefs could jeopardize the survival of rare species such as the Mekong giant catfish, which spawns in the rapids. The reefs also play an important role in producing oxygen, reducing pollution and aiding in decomposition of vegetation. Because of their high productivity, islets and rapids are a source of food and income for small fishermen who rely on the river for their livelihoods.

Destruction of the rapids and dredging of the river channel may also have serious impacts on water flow, impacting people who live along the banks of the Mekong and have adapted to the river's flood-drought cycle. Without the rapids, the river may flow faster, eroding the riverbanks and damaging riverside plantations.

Impacts on Cambodia and Vietnam

While the navigation project directly affects people living in China, Burma, Laos and Thailand, it is also likely to have far-reaching impacts on people in downstream countries. Cambodian and Vietnamese officials have raised concerns that fewer reefs upstream could change the flow of water into their countries, posing problems for farming and other activities. The project could also affect fisheries by destroying spawning grounds for fish that live in Cambodia and Vietnam but migrate upriver to lay their eggs. Despite these potential impacts, people in Cambodia and Vietnam have not been consulted.

Surveys in Thailand an indicator of potential impacts

Recent surveys have documented that rapids, shoals and reefs in Thailand that are supposed to be destroyed for the navigation project are crucial for the subsistence livelihoods of local people. The surveys are an indicator of the likely impacts that the navigation project will cause all along the river. The studies have found that local people from Chiang Saen to Chiang Khong rely on riverine plants, such as Mekong seaweed, that grow in the rapids for food and income. The plants, sand dunes, whirlpools and small swamps provide vital spawning ground for Mekong fishes, including the endangered Mekong giant catfish. Blasting of the rapids would destroy important fish habitat and threaten the income and food security of villagers living in the area.

Further, villagers living in Huai Luk-Waing Kaen, Thailand, will lose their common customary lands without compensation due to dredging of the shoal. Fishermen in Chiang Saen can no longer use traditional fishing boats due to waves created by large ships. Last summer, the number of fish caught by fishermen along the Thai-Lao border also decreased because implementation of the project altered water levels and currents in the Mekong.

Call for halt to project until studies completed

Given the impacts outlined above, we respectfully urge the Chinese, Lao, Myanmar and Thai governments to stop all work on the Lancang-Mekong Navigation Channel Improvement Project immediately and ensure that comprehensive environmental and social impact assessments are conducted that will examine potential impacts along the Mekong, from China downstream to Cambodia and Vietnam. These assessments should be carried out in a transparent and participatory process by a study team selected by government officials, villagers who will be affected by this project and civil society organizations in the Mekong region. The health and vitality of the Mekong River and the lives of those who depend on it deserve nothing less.

Thank you for your attention.
