The Harmful of the Hydro-Electric Dams Upstream of the Mekong River Effect on the Ecosystems and Livelihoods of People in Mekong Delta, Vietnam

The development of hydro-electric projects of the upstream Mekong countries has been and will be inevitable and greatly impact on the downstream areas, in which the Mekong Delta is suffering a lot of losses, especially for Vietnam. The processes have been happening at the same time: the process of depleting water, for agriculture, for industry, for daily life, and people's livelihoods. The processes, at the same time the effects that resonate with the process of climate change, cause great harm [1]. The drought has accelerated the acidification process, because the potential drought of acid sulfate soil (1,700,000 ha) will become intense, damaging the ecosystem and human livelihoods. The drought due to the construction of hydro-electric dams upstream (especially Lan Thuong River, China) makes the process of salinization with saline intrusion fierce (seawater 4 g/liter) [2]. Many, penetrating into the interior fields more than 100KM, the harm is extremely great. If they want to reduce the harm, the Mekong River Commission must ask the upstream countries to share it with the downstream.
