How have construction of hydropower dams along the Mekong River Basin affected Cambodia?
These dams have disrupted the hydrology of the Mekong River and its tributaries. Unseasonal changes to water levels, flow rates, and turbidity are having ecologically negative synergistic effects, not only on areas immediately nearby these hydropower projects, but also on places many km away in neighboring countries.
What are the issues caused by hydropower dams along the Mekong River?
Hydropower dams have had a dramatic effect on the Mekong river over the last two decades, resulting in unseasonable flooding and droughts, low water levels in the dry season, and drops in the amounts of sediment carried by the river, with drastic consequences for biodiversity and fisheries.
What is Mekong River basin?
The Mekong River is the longest river in Southeast Asia. The Upper Mekong River Basin comprises the Tibetan Plateau, the Three Rivers Area and Lancang Basin in China and Myanmar. The Lower Mekong River Basin is made up of the Northern Highlands, the Khorat Plateau, the Tonle Sap Basin and the Mekong Delta.
Why is the Mekong River Drying Up?
While drought ravaged the lower Mekong Basin in 2019, there was above-average rainfall and snowmelt in China and the flow from these events was nearly all retained in China’s dams. China’s actions have been a cause of droughts over a number of years. China is impounding more water than ever before.
How many dams are planned on the Mekong River?
Over 120 dams are planned for the tributaries and 11 large-scale hydropower dams are slated for the Lower Mekong mainstream, which has the potential to produce over 13,000 MW of hydropower4.
Why is the Mekong river Drying Up?
What are the advantages of the Mekong river dam?
The three major advantages put forward in support of dam construction are hydropower, irrigation, and flood control. All require impoundment of the river, displacement of communities and provision of their major benefits at some distance from the site of the dam.
Is Mekong River clean?
It moves 475 km3 of water annually and supports over 70 million people who rely on it as their main source of water. However, indiscriminately disposed waste and sewage discharge along the river’s length has turned the Mekong into one of the world’s ten most polluted rivers.
Why is the Mekong Basin important?
From its source in the Tibetan Plateau to its end in Vietnam, the Mekong River is a critical source of drinking water for the millions of people who live in its watershed.
Why is the Mekong River Basin important?
The Mekong River connects China, Laos, Thailand, Cambodia and Vietnam physically and economically. The river is a lifeline for the entire basin, sustaining economies and livelihoods across the entire region.
Are there any hydroelectric projects in the Mekong River?
An additional 134 projects are planned for the lower Mekong, which will maximize the river’s hydropower generating capacity. The single most significant impact—both now and in the future—on the use of water and its management in the Mekong Region is hydropower.
Is the Mekong River basin wet or dry?
Fig. 1. The Mekong River basin: hydropower dams ( MRC (Mekong River Commission), 2015, Water, Land, and Ecosystems – Mekong, 2017) and mainstream hydrological stations analyzed in this study. The LMB has a monsoonal climate with distinct wet and dry seasons.
Where are the hydro power dams in China?
In the Upper Mekong River Basin (UMB), extensive hydropower development has also occurred as part of China’s development strategy. China has constructed 11 hydropower dams, of which two are large storage dams, along the mainstream in the Upper Mekong Basin.
What is the purpose of the Mekong River Commission?
In response to this dynamic situation, the Mekong River Commission (MRC) focuses on advancing regional cooperation for the sustainable management of the growing number of hydropower projects from a river basin management perspective. The MRC supports countries through:
