Data on agricultural, hydropower, saltwater intrusion and rainfall patterns in Vietnam Mekong Delta explains where the country’s food comes from, why it’s disappearing and what can be done about it.
The fertile Mekong Delta is a crucial region for Vietnam’s continued food and economic security but a variety of factors have wreaked havoc on how Vietnam grows food, catches fish and ultimately survives a radically changing environment. Here, reporters analyze 20 years of data on agricultural, hydropower, saltwater intrusion and rainfall patterns in Vietnam’s Mekong Delta (VMD) to explain where the country’s food comes from, why it’s disappearing and what can be done about it.
1. Disappearing waters
Vietnam’s flood plains are disappearing, and fish, rice and people along with it. The flood peak in Tan Chau and Chau Doc in 2020 is only about 60% of that in 2002. From now on, VMD will have to wait from 50 to 100 years to have a big flood season. Within 15 years, the amount of fish caught in An Giang has plummeted by two-thirds.
Đồng bằng sông Cửu Long (ĐBSCL) của Việt Nam là đồng bằng lớn thứ ba trên Trái Đất, là nơi sinh sống của gần 18 triệu người với sinh kế chủ yếu là sản xuất nông nghiệp và nuôi trồng thủy sản. Được coi là “Vựa lúa” của Việt Nam, ĐBSCL đóng góp hơn một nửa tổng sản lượng gạo của cả nước và 95% sản lượng gạo xuất khẩu, góp phần đưa Việt Nam trở thành quốc gia xuất khẩu gạo lớn thứ ba thế giới. Khu vực này cũng đóng góp 70% sản lượng trái cây và hơn 60% sản lượng thủy sản xuất khẩu của cả nước.1
The Lao Government has given the green light for two private companies to carry out a feasibility study on the construction of a 220kV transmission line which would carry electricity from five dams in northern Laos to Vietnam.

The Mekong River Commission on Thursday called on China and Southeast Asian to better coordinate management of Mekong hydropower dams and reservoirs after three years of record low flows and extra dry conditions.
The Mekong River’s flow dropped to the lowest levels in more than six decades from 2019 to 2021 due to an increased number of reservoirs, dams and other water storage, a worsening of the climate situation and unusually low rainfall, a new MRC river flow report showed.
Dry conditions in the past three years have affected navigation, river ecosystems and riverbank stability in the region where tens of millions of people depend on the Mekong for their livelihoods.
Các chuyên gia đến từ Tổ chức Bảo tồn Thiên nhiên Quốc tế (IUCN) và Viện Di sản Thiên nhiên Hoa Kỳ (NHI) mới đây đã đưa ra khuyến nghị cả Campuchia và Việt Nam sẽ phải chịu hậu quả nặng nề từ đập Sê Kông 1. Với Campuchia là sản lượng đánh bắt cá giảm đáng kể và với Việt Nam là giảm lượng trầm tích bồi đắp.
Sông Sê Kông bắt nguồn từ Thừa Thiên-Huế, Việt Nam chảy qua CHDCND Lào, và đổ vào Campuchia. Đây là dòng nhánh lớn cuối cùng của sông Mê Công chưa bị cản trở bởi các đập thủy điện và có tầm quan trọng đặc biệt, không thể thay thế được đối với an ninh lương thực của khu vực và với sức sản xuất của vùng Châu thổ Sông Mê Công. Hai sông nhánh lớn khác, cùng với Sê Kông tạo thành các lưu vực 3S, là Srepôk và Se San đã bị chặn ngay trước nơi chúng nhập với dòng chính sông Mê Công bởi đập Hạ Sesan 2 được hoàn thành vào cuối năm 2017.
Washington [US], March 1 (ANI): Raising concerns over the dipping water-levels of the Mekong River and upstream dams in China, Principal Deputy Assistant Secretary of State for East Asian and Pacific Affairs Ambassador Atul Keshap points out that upstream dams in China that exacerbate droughts are hurting the communities and ecosystems that have relied for countless generations on the Mekong River’s natural flood pulse.
Speaking at the Indo-Pacific conference on Strengthening Transboundary River Governance, Keshap on Saturday (local time) said the conference report launched at the event is excellent and summarizes our work examining the challenges facing the Mekong River basin and its ties to the economies, livelihoods, and culture of nearly 70 million people.
“We remain concerned just as we were in October during the conference–that record droughts and the upstream dams in China that exacerbate them are hurting the communities and ecosystems that have relied for countless generations on the Mekong River’s natural flood pulse,” he said as reported by the Frontier Post.

BANGKOK: A US-funded project using satellites to track and publish water levels at Chinese dams on the Mekong river was launched on Monday (Dec 13), adding to the superpowers’ rivalry in Southeast Asia.
The 4,350km waterway – known as the Lancang in China and flowing south through Myanmar, Laos, Thailand, Cambodia and Vietnam – has become a focus of competition.Advertisement

Germany has provided equipment to the Mekong River Commission to monitor the environmental impacts of two mainstream dams on the lower reaches of the Mekong River.
The equipment, worth around $600,000, meant to help monitor the impacts of Laos’s Xayaburi and Don Sahong dams, was handed over on Tuesday as part of the German government’s support for the MRC’s Joint Environment Monitoring of Mekong Mainstream Hydropower Projects (JEM) program, which is now in the pilot stage.
HONOLULU (29 July 2020)—In recent years, relations with Southeast Asia have emerged as an important pillar of US engagement with the Indo-Pacific region. The Association of Southeast Asian Nations (ASEAN) is central to US foreign policy in the region, with a growing focus on the five countries bound together by the Mekong River—Cambodia, Lao PDR, Myanmar, Thailand, and Vietnam.
As they emerge from a tumultuous history, these countries must confront new elements of great-power competition even as their youthful populations push for economic growth and integration into the wider region and the world. Among other impacts, urbanization, infrastructure expansion, and climate change all affect the Mekong River, the natural resources along its banks, and the 240 million people who live in the region.
BANGKOK: Laos is pushing ahead with a hydropower project on the Mekong River, despite reservations aired by neighbouring countries over its potential to harm fisheries and farming downstream, the Mekong River Commission (MRC) said on Wednesday (Jul 10.

For three decades, China has been building dams on the upper Basin of the Mekong River, worrying countries downstream that China could one day turn off the tap. New data shows that for six months in 2019, while China received above average precipitation, its dams held back more water than ever — even as downstream countries suffered through an unprecedented drought. These new findings confirm what many had long suspected: China is impounding much more water than it ever has before and is causing erratic and devastating changes in water levels down stream.

The Eyes on Earth report, Monitoring the Quantity of Water Flowing Through the Upper Mekong Through Natural (Unimpeded) Conditions, published this week by Pact, shows that deviations from normal flow patterns began to occur with the operation of the first large hydropower dam on the Upper Mekong mainstream in 2012. Using satellite data on the Upper Mekong from 1992 to 2019, matched against daily measurements of river height downstream at Chiang Saen, Thailand, the research shows unusual fluctuations in recent years. The report concludes that cooperation between China and the Lower Mekong countries to simulate the natural flow cycle of the Mekong could potentially improve low-flow conditions and benefit all communities in the Mekong River Basin.
