The dangers of the construction of hydroelectric dams upstream of the Mekong River adversely effect on the ecosystems and livelihoods of people in the Mekong Delta, Viet Nam

Abstract

The main purpose of the article is with the results of scientific and serious research to let the world know the enormous harm of upstream hydroelectric dams, mainly of China, causing huge, multifaceted, and global damage. impact on the downstream area, but especially on the Mekong Delta of Vietnam: ''Wetland'' will become ''dead land'' The development of hydro-electric projects of the up-stream Mekong countries has been and will be inevitable and greatly impact on the down-stream areas, in which the Mekong Delta is suffering a lot of losses., especially, for Viet Nam.. 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. 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 hydroelectric dams upstream (especially Lan Thuong river, China) makes the process of salinization with saline intrusion fierce (seawater 4 gr/L) Many, penetrating into the interior fields more than 100KM, the harm is extremely great. If want to reduce the harm, the Mekong River Commission must ask the upstream countries to share it with the downstream
