In the Mekong River, the species is known at least as far north as Louang Phrabang in northern Laos. Thailand will be impacted, as its fish stocks in the Mekong will decline by 55%, Laos will be reduced by 50%, Cambodia by 35%, and Vietnam by 30%. 扎曲 Pinyin Zāqū) Chinesisch: Lancang Jiang ( chin. Regional spe-cies richness (Table S1) ranges from 484 species in the Mekong Delta to only 24 species in the Chinese headwaters far north. This makes the Mekong second to only the Amazon for the variety of fish species present. Between 1973 and 2009, the Greater Mekong subregion (excluding China) lost about a third of its forest cover. Within the Mekong River system there are flourishing fisheries that exploit a large number of species. From 5.3 to 3.5 ka the delta advanced across a broad embayment formed between higher ground near the Cambodian border and uplands north of Ho Chi Minh City. The Mekong basin is not normally considered a seismically active area as much of the basin is underlain by the relatively stable continental block. Its estimated length is 4,350 km (2,703 mi), and it drains an area of 795,000 km 2 (307,000 sq mi), discharging 475 km 3 (114 cu mi) of water annually. The commercially valuable fish species in the Mekong are generally divided between "black fish", which inhabit low oxygen, slow moving, shallow waters, and "white fish", which inhabit well oxygenated, fast moving, deeper waters. The Greater Mekong also hosts a self-cloning skink and a fish with vampire fangs, among many other recently discovered species. An estimated 2.56 million tonnes of inland fish and other aquatic animals are consumed in the lower Mekong every year. (2017). , Sewage treatment is rudimentary in towns and urban areas throughout much of the Mekong's length, such as Vientiane in Laos. Migration status is known for only 24% of those species, and of those, 87% are migratory . In a worst-case scenario, China could well make demands on thirsty downstream countries who would not be able to refuse.  At this time the shoreline of the South China Sea almost reached Phnom Penh and cores recovered from near Angkor Borei contained sediments deposited under the influence of tides, and salt marsh and mangrove swamp deposits. Studies of the provenance of sediments in the Mekong delta reveal a major switch in the source of sediments about eight million years ago (Ma). , New species are regularly described from the Mekong. water purification) benefits to people, supporting local economies and livelihoods across the basin. In: Renaud, F. G. and C. Kuenzer (eds. Ninety percent of plastic in the oceans is flushed there by just 10 rivers. The endangered Siamese crocodile (Crocodylus siamensis) occurs in small isolated pockets within the northern Cambodian and Laotian portions of the Mekong River. It’s not just tigers and giant catfish.  This value increases considerably when the multiplier effect is included, but estimates vary widely. The Chinese and Thai governments agreed to build the bridge and share the estimated US$33 million cost. Furthermore, it points to the shocking decline in freshwater species, with the iconic Mekong giant catfish and population of Irrawaddy river dolphins among a dozen species on the critically endangered list – just one small step from extinction. The main hydrological contributions to the mainstream in this reach come from the Se Kong, Se San, and Sre Pok catchments. In: Sustainability Science 8 (4), pp. Leinenkugel, P., C. Kuenzer, N. Oppelt and S. Dech (2013): Characterisation of land surface phenology and land cover based on moderate resolution satellite data in cloud prone areas – A novel product for the Mekong Basin. Around the Tonle Sap Lake in Cambodia, more than 1.2 million people live in fishing communes and depend almost entirely on fishing for their livelihoods. The second group are those on the right bank, mainly the Mun and Chi Rivers, that drain a large part of northeast Thailand. Together, these rivers make up the largest hydrological sub-component of the lower basin.  From the point where it rises to its mouth, the most precipitous drop in the Mekong occurs in the upper Mekong basin, a stretch of some 2,200 km (1,400 mi). The Mekong giant catfish and the Nile perch of Lake Victoria provide contemporary cases. Asian elephant  The Lao Government is aiming to lift the nation out of poverty by making it "the battery of Asia". It is also one of the most biodiverse rivers; serving as home to many species that are blocked or hindered by the development of dams. Only the Amazon boasts a higher level of bio-diversity.  Between 1997 and 2015, an average of two new species per week were discovered in the region. The Mekong River produces fish when it flows free and clean electricity when it’s dammed. The bridge will be 691.6 meters long and have 8.5 meters wide two-lane motorway.. ): The Mekong Delta System.  A carnivorous creature that feeds on fish, amphibians, reptiles and mammals, this crocodile lives in and around the Mekong River in small numbers. Among the fish species in the Mekong River, the Mekong giant catfish (scientific name: Pangasianodon gigas) is the biggest. Several giant freshwater species are listed in the Red Book of Threatened Species of the International Union for Conservation of Nature (IUCN), including giant Australian fish - the largest freshwater fish of the same family with the barbeled houndshark. The boundary between Reach 2 and 3 is where the Mekong hydrology starts to change. Phnom Penh Agreement between Cambodia and Vietnam on the Transit of Goods, 7 September 2000. DOI: 10.1080/01431161.2014.890377. During the wars in Indochina in the 1970s, a significant quantity of explosives (sometimes, entire barges loaded with military ordnance) sank in the Cambodian section of the Mekong (as well as in the country's other waterways).
