Dams threaten “millions of Mekong livelihoods”

PHNOM PENH, 22 July 2009 (IRIN) - For thousands of years, the Mekong
River has nourished civilizations and housed one of the world’s most
diverse populations of fish and plants.

Yet 17 dams recently built on the Mekong and its tributaries in China,
Thailand, Laos, and Vietnam, as well as 11 more in the planning
process, are threatening Mekong fisheries – and thereby the food
security they have provided for millions, critics warn.

“People affected could number in the millions, due to the extensive
changes expected to the river’s ecosystem downstream,” Aviva Imhof,
campaigns director of International Rivers, an NGO based in
California, told IRIN.

Most alarming, NGOs say, is a cascade of eight dams being built in the
Upper Mekong in China, the origin of Southeast Asia’s largest river,
which could alter the ecosystem downstream for Thailand, Laos and
Cambodia.

Of the eight dams in China, four have been completed. NGOs claim they
are already undermining fish populations and causing erosion in
downstream Myanmar, northern Thailand and northern Laos.

The dams are allegedly blocking Mekong fish from travelling upstream
to spawn, threatening fisheries.

Livelihoods

Between 60 and 65 million people live in the Mekong River basin and
are overwhelmingly dependent on fisheries.

About 80 percent of their protein intake comes from fish, with an
estimated value of about US$2.5-$3 billion a year, the Bangkok-based
NGO Towards Ecological Recovery and Regional Alliance (TERRA),
reports. They eat more than 1.5 million tonnes of fish per year,
according to conservative Mekong River Commission (MRC) estimates.

The MRC, an inter-governmental body of Mekong countries based in
Vientiane, Laos, says the basin provides a wide variety of breeding
habitats for more than 1,300 species of fish, while the annual rise
and fall of the river ensures a nutrient-rich environment on which the
fish can feed.

Aside from the fishermen, thousands more earn their livelihoods making
and selling food products and fishing gear and repairing boats,
according to the MRC.

Resettlement

“Local people will became the victims of this [the dams], and will not
necessarily receive any benefits,” Premrudee Daoroung, co-director of
TERRA, told IRIN.

In China, two resettled communities have not received adequate
compensation, and seen lower fish catches, as well as an increased
incidence in disease, according to International Rivers.

“There has been no investigation into this, nor any attempt to
document the downstream impacts by the Chinese government or other
regional governments,” Imhof said.

In landlocked Laos, one of the region’s poorest and least developed
nations, a series of relatively small dams and diversions has already
led to the forced relocation of thousands of indigenous peoples.

The controversial Nam Theun 2 Dam project, which will flood more than
600 sqkm, will displace at least 7,000 when completed, and affect many
more, according to Minority Rights International.

Pushing for development

Chinese companies have long been building dams to develop the Yunnan
province in the southwest, a mountainous frontier known for its vast
rivers and natural resources.

Dams provide the renewable electricity needed to support China’s rapid
economic growth, and reduce its dependence on coal plants. Governments
downstream claim the hydroelectric dams will cut electricity costs.

The World Bank has estimated that Cambodia, for example, has some of
the highest electricity costs in the world.

To increase the supply of electricity for all Southeast Asia, Laos is
planning at least 30 dams on Mekong River tributaries or smaller
streams that branch off from the main river.

“Laos knows that Thailand will be the biggest buyer of their
electricity and this will benefit the country economically,” Daoroung
told IRIN. “Thai people, at the same time, have been told by the
government… that the country plans to buy very cheap electricity from
Laos.”

But despite the negative impacts, supporters say the dams could help
local communities, who face annual floods and droughts due to extreme
fluctuations in rain levels.

“Dry season water levels could increase, making water available for
irrigation and urban water supply,” Damian Kean, a spokesman for the
MRC in Vientiane, Laos, told IRIN by e-mail.

“China has also clearly stated it will operate the upstream projects
so that river flows downstream are maintained at acceptable levels,”
he added.
