The Cambodian government has committed to the construction of five dams along the Mekong River in order to meet a huge demand for electricity, but environmental groups warn that severe repercussions loom for this strategy.
“While each project proposed in Cambodia comes with a different set of impacts, large dams are likely to widen the gap between the rich and the poor, increase malnourishment levels and lead to an environmentally unsustainable future,” Ame Trandem, South East Asia programme director for International Rivers, told IPS.
Four dam projects have been approved so far in Cambodia, with one already operational. All are being developed by Chinese companies on build-operate-transfer agreements, according to Trandem.
The Mekong River runs through six countries, including China and Vietnam, most of which are planning the construction of hydroelectric dams.
“The plans to build a cascade of 11 Mekong mainstream dams is one of the greatest threats currently facing Cambodia,” said Trandem.
The mandate on planning and development of hydropower in Cambodia lies within the ministry of industry, mines and energy, which did not respond to requests for comment.
Another danger of damming the Mekong is the threat to the Mekong delta, an extremely fertile area of land which is responsible for much of the region’s rice supply.
“As the Mekong River feeds and employs millions of people in the region for free, it would be irresponsible to proceed with the Xayaburi and other mainstream dams,” said Trandem.
The Mekong is one of the only rivers in the world to reverse its flow in the dry season. This natural mechanism buffers the intrusion of salt water from the South China Sea into the delta, and could be upset by upstream development.
Dams also block fish migration routes, alter flows, and change aquatic habitats, so these projects are also likely to have an adverse effect on Cambodia’s fisheries.
