ĐBSCL sẽ tiếp tục đối mặt với nguy cơ xâm nhập mặn, xói lở, mất nguồn lợi thủy sản nếu dự án thủy điện Pắc-Beng do Trung Quốc đầu tư xây dựng ở Lào hoạt động.

Tại hội thảo Tham vấn dự án (DA) thủy điện Pắc-Beng của Lào trên dòng chính sông Mê Kông ngày 5.5, ông Trần Đức Cường, Phó chánh văn phòng thường trực Ủy ban Sông Mê Kông VN, cho biết DA thủy điện Pắc-Beng thuộc H.Pắc Beng, tỉnh Oudomxay, Lào, cách thủ đô Vientiane hơn 600 km về phía thượng lưu, cách biên giới VN 1.933 km.

Chỉ đúng nguyên nhân ĐBSCL sạt lở và các khuyến nghị

BĐV – Bài viết của GS.TSKH Nguyễn Ngọc Trân – Nguyên Chủ nhiệm Chương trình cấp Nhà nước Điều tra cơ bản tổng hợp ĐBSCL về tình hình sạt lở ở khu vực này.

Tình hình sạt lở bờ sông, bờ biển ở ĐBSCL ngày càng nhiều và nghiêm trọng.

Các nguyên nhân cơ bản thường được nói đến thời gian gần đây là do thiếu hụt trầm tích bị các đập thủy điện trên dòng chính sông Lancang – Mekong giữ lại, và do lạm khai thác cát sông.

Hiểu sâu để có giải pháp tốt. Nhằm mục đích này, xin đóng góp một số ý kiến vào nhận thức khách quan vấn đề sạt lở và từ đó một số việc cần làm theo thiện ý của tác giả.

International Waters Governance – Mekong

Mekong

Legal Basis:

The Mekong River Commission (“MRC”) governs the allocation and utilization of the Mekong River waters by four countries – Thailand, Cambodia, Vietnam, and Laos. The MRC was founded in 1995 pursuant to the Agreement on the Cooperation for Sustainable Development of the Mekong River Basin (the “1995 Agreement”), which was signed and entered into force at Chiang Rai, Thailand on 5 April 1995. On 5 April 2010, the heads of state of Thailand, Cambodia, Vietnam, and Laos met in Hua Hin, Thailand for the first MRC Summit to mark the 15th anniversary of the adoption of the 1995 Agreement. The parties adopted a joint declaration—the Hua Hin Declaration—reaffirming their commitment to implementing the 1995 Agreement. The 1995 Agreement was the result of more than 40 years of regional and supra-regional efforts to manage the resources of the Mekong River Delta. In the mid-1950s, the United Nation’s Economic Commission for Asia and the Far East (“ECAFE”) and the U.S. Bureau of Reclamation sent teams to the Mekong to examine water management issues. Both ECAFE and the U.S. Government published detailed reports of their findings. Tiếp tục đọc

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
