ANTICIPATED GEOMORPHIC IMPACTS FROM MEKONG BASIN DAM CONSTRUCTION

By Z.K RUBIN, G.M. KONDOLF, AND P. CARLING (2014)

Dam locations are indicated for two scenarios: definite future, and full-build. 
Main stream dams are included in full-build scenario, but represented separately.

Mekong Delta faces increased risk of landslides as sediment loss continues

Last update 07:40 | 17/05/2017

VietNamNet Bridge – Every year, 55 million tons of sediment is lost from the rivers in Mekong Delta, 90 percent of which is sand.

Nguyen Huu Thien, an independent expert, said the Mekong Delta has been taking shape for the last 6,000 years thanks to alluvial accretion. But the volume of sediment in the river and canal system has decreased gradually, leading to an increased risk of landslides.

The coastal provinces in the western part of the southern region are also directly affected by the change.

The alluvium from river mouths to the sea has the function of protecting the coast, easing the impact from waves hitting the coast. When there is not enough silt, the sea water will cause erosion. Tiếp tục đọc

The environment and lives of dozens of millions of people living in the Lower Mekong Basin are being threatened as the Mekong River is expected to see yet another hydropower dam construction, experts said at an international conference on Friday.

Experts all express concerns over the Laos-proposed Pak Beng dam, the latest to be built on the Mekong River, as they convened for a consultation process held by the Vietnam Mekong River Commission in the southern Vietnamese city of Can Tho. Tiếp tục đọc

Mongabay Series: A plan to save the Mekong Delta

  A plan to save the Mekong Delta

Mongabay Series:
Part 1 – Will climate change sink the Mekong Delta?
Part 2 – Vietnam sweats bullets as China and Laos dam the Mekong
Part 3 – Mother Nature and a hydropower onslaught aren’t the Mekong Delta’s only problems
Part 4 – A plan to save the Mekong Delta

18 October 2016 / David Brown

Rising seas and upstream dams are threatening to hammer the fertile region. Can Vietnam act in time to stave off disaster?

  • The Mekong Delta Plan is the product of several years’ work by Dutch and Vietnamese officials, supported by a platoon of experts from both nations.
  • It’s a blueprint for dealing not only with the effects of climate change and upstream dams but also with certain shortsighted activities by the Vietnamese themselves.
  • The region’s farmers as well as the relevant branches of government must be persuaded to buy into the plan.
This is the final installment of an in-depth, four-part series exploring threats facing the Mekong Delta and how they might be addressed. Read the firstsecond, third and fourth installments.“I think this year Vietnam got a taste of the new normal,” said Dinh Tuyen, my journalist friend in bustling Can Tho, the Mekong Delta’s hub city. “Less fresh water from rains or from up the river, and more salt water as sea levels rise.”We’d been talking about a story Tuyen had written in May for Thanh Nien, a leading Vietnamese daily. It featured photos of blue-green river waters, and called attention to a remarkable development: the Mekong’s southern branch was not, as usual, muddy with a cargo of silt. Tiếp tục đọc

Climate change and dams going in upstream are threatening to render the crucial region unviable. But are the Delta’s biggest problems of Vietnam’s own making?

  • Vietnam’s Mekong Delta, home to nearly 20 million people, is one of the most highly productive agricultural environments in the world, thanks in part to an elaborate network of canals, dikes, sluice gates and drainage ditches.
  • On the strength of Delta agriculture, Vietnam has gone from a chronic importer of rice to a major exporter.
  • But farmers in the region are critical of the government’s food security policies, which mandate that most of the Delta’s land be devoted to rice production. And many of them are taking measures to circumvent those rules, in ways that aren’t always friendly to the environment.
  • That’s just one example of how water and land-use policy in the Delta is undermining efforts to protect the vulnerable region from climate change and upstream development.

This is the third article of an in-depth, four-part series exploring threats facing the Mekong Delta and how they might be addressed. Read the  first, secondthird and fourth installments. Tiếp tục đọc
