Mekong delta homestay
According to relevant reports Netease, since the beginning of this year, five provinces in southwest China suffered a severe drought, no rain for months continued into March, Thailand, Laos, Vietnam and Cambodia are beginning to have serious drought, which flows through the five countries Mekong River water level dropped to the lowest level in 20 years. To this end, the lower mekong delta homestay tour countries criticized China's Upper Mekong dams in the drought intensified. In fact, the Mekong River since ancient times "is not and the water," joked, but the debate on this issue has continued for decades.
Around the Mekong River water resources development of the three disputed
Controversial one: repair of dams in the upstream river will affect the ecological balance?
Environmental protection Organization: Mekong dams accelerated the reduction of water, water quality, changes in water flow has caused a series of questions: for example, Vietnam's "rice bowl" Mekong Delta River erosion are due to seasonal flooding and the unique Arid Changes affected.
Thai fishermen: the unpredictability of salt to bring the production of agricultural and fishery losses. Thailand Parmon dam near the fishermen said, "when the dam burst the first time, Hanoi was scared to scattered fish. Dam projects after the beginning of the year, Hanoi has no fish."
The Chinese government: the dam is the biggest ecological impact of sediment to flow downstream fewer, because the silt gathered in a reservoir, but this objective so that the Mekong River for irrigation and navigation more convenient. Former minister of China Ministry of Water Resources, Association of China Wang Shucheng more dams, "said the ecological water Environment Impact only on the watershed area, but if you do not affect the development and construction of water damage to the global ecological environment. "
Controversy II: repair of dams in the upper reaches of the river is dirty water will decrease?
Environmental protection Organization: Council. Construction of dam would change the law in each of the ups and downs the water, which makes water the downstream countries subject to the upper reaches of the state regulation of water demand. Mekong River in the past few months the region is indeed reduced precipitation, which is not only a natural drought, or by the upper reaches of the impact of large dams projects.
Mekong River Commission: no. Mekong River water level drop is caused by the drought rather than natural causes caused the dam. Rainfall in the Mekong River Basin in 2009 dropped by 30%, while the rainy season but end month and a half earlier than usual, which makes the Mekong and its tributaries, smaller volume of water. "Upstream flood control dams have a positive effect", the Mekong River Commission President Jeremy Bird said, "If there are no dams upstream, downstream in January of this year is likely to have been shortage of water supply problems."
Chinese government: no. Average annual runoff of the departure Lancang Mekong River to the sea only 13.5% of average annual runoff of the Mekong water main outside the Mekong River from China (86.5%). Water evaporation from reservoirs, small hydropower, hydropower does not consume water running. Moreover, China has no inter-basin water transfer Lancang River Basin Plan, along the very few industrial and agricultural water consumption, the demand on limited water resources. Lancang River Hydropower Development almost no effect on downstream water.
Controversial three: no effect after the completion of the dam, who is in charge?
Mekong River Commission (MRC): Mekong River Commission, an advisory in the form of Thailand, Cambodia, Vietnam, Laos, the development of water resources issues in four countries for data detection and information analysis, but on the national implementation of the project without any decision. At present, the downstream countries of dams on river water temperature conditions on the authority of the data, mostly from the agency on rainfall, river levels and floods clock of the periodic reports.
China: China's Yunnan Province has its own testing system, but never in the past 15 years, the downstream country open. March 25 this year, China announced its willingness to offer the first time in Yunnan Jinghong Hydropower Station Dam and water level information Manwan. However, the Chinese government within the data provided only for the assessment of the dam.
Environmental organizations: Thailand's "Siamese River of Life," "Save the Mekong Union" and other environmental organizations, environmental groups are opposed to dam the Mekong River (especially hydroelectric dam) of the active non-governmental forces, they through the organization of the various inter-regional forums, published articles in the media side of "supervision" of China and its construction of the dam.
