Migration status is known for only 24% of those species, and of those, 87% are migratory [18]. The Mekong giant catfish and the Nile perch of Lake Victoria provide contemporary cases. 133–166. [12] As elsewhere in the basin, forest cover has been steadily reduced during the last three decades by shifting agriculture and permanent agriculture. We identified 877 fish species in the MRB (not including estuary marine species). For example, if runoff from melting snow in any given year is very low, then flows upstream of Vientiane-Nong Khai would be lower. The Bassac River is the first and main distributary of the Mekong. The Mekong boasts the most concentrated biodiversity per hectare of any river.[41]. OAAs account for about 20% of the total Mekong catch. [12], The Mekong delta in Vietnam is farmed intensively and has little natural vegetation left. This number is constantly increasing as many previously unknown species are found. Only the Amazon boasts a higher level of bio-diversity. Adult fish occur in both Chiang Rai and Loei Provinces in Thailand, and young fish … It is impacting the ecosystem, disturbing the migratory patterns of fish as well as riverbank plants and local agriculture downstream.[56]. In: Renaud, F. G. and C. Kuenzer (eds. The species is considered virtually extinct in the wild with numbers estimated between 50 and 4,000 in Thailand due to habitat destruction and hunting for skins. [46] Aquaculture yields about two million tonnes of fish a year. [12] Sandy and saline soils are the most common soil types, which makes much of the land unsuitable for wet rice cultivation. The last three can grow up to about 3 m (9.8 ft) in length and weigh 300 kg (660 lb). It is the world’s third most diverse fish population, with 1,148 fish species, after the Amazon and Congo river basins. Irrawaddy dolphins leaping in Thai section of the Mekong. Here the mainstream divides into a complex and increasingly controlled and artificial system of branches and canals. Unlike the Friendship Bridges, it is not a border crossing. Only the Amazon boasts a higher level of bio-diversity. Thereafter, it turns and runs more or less directly south, crossing into Cambodia. Many hydrological aspects of the lower basin start to change rapidly at the downstream boundary of this reach. When the Mekong is low, the Tonle Sap is a tributary: water flows from the lake and river into the Mekong. The low tide level of the river in Cambodia is lower than the high tide level out at sea, and the flow of the Mekong inverts with the tides throughout its stretch in Vietnam and up to Phnom Penh. [12], Reach 6: Phnom Penh to the South China Sea. Although the pattern of the annual hydrograph is fairly predictable, its magnitude is not. [6] Inaugurated in 2010, it is the longest main span cable-stayed bridge in Southeast Asia. In: International Journal of Remote Sensing 35 (8), pp. Muntjac རྫ་ཆུ་ ), transkribiert ins Chinesisch Zaqu ( chin. Agreement between and among the Governments of the Laos, Thailand, and Vietnam for Facilitation of Cross border Transport of Goods and People, (amended at Yangon, Myanmar), signed in Vientiane, 26 November 1999. Threatened species in the Mekong River Ecoregion include mammals such as the iconic Irrawaddy dolphin and gigantic fish like Mekong giant catfish, giant carp, and giant freshwater stingray, all of which can exceed 200 kg in weight. The Fourth Thai–Lao Friendship Bridge opened to traffic on 11 December 2013. 180–198. Kuenzer, C., I. Campbell, M. Roch, P. Leinenkugel, V. Q. Tuan and S. Dech (2012): Understanding the impact of hydropower developments in the context of upstream–downstream relations in the Mekong river basin. [60], Construction of Myanmar–Laos Friendship Bridge started on 19 February 2013. It is the world's twelfth longest river and the seventh longest in Asia. The flow level falls again, even with the right bank entry of the Mun-Chi system from Thailand. However, the hydrological impacts of land cover changes induced by the Vietnam War were quantified in two sub-catchments of the lower Mekong River basin. The seasonal cycle of changing water levels at Phnom Penh results in the unique "flow reversal" of water into and out of the Great Lake via the Tonle Sap River. Understanding the nature and timing of the elevation of Tibet (and the Central Highlands of Vietnam) therefore helps explain the provenance of sediment reaching the delta and the Tonle Sap Great Lake today. [9][10]. National Geographic term it as the “world’s most productive river” due to its plethora of fish and its tendency to product array of “mega-fish” such as the giant catfish. In this way, maps were created to show the numbers of potential trigger species per … [12] With upland shifting agriculture (slash and burn), soils recover within 10 to 20 years but the vegetation does not. [13], Loss of forest cover in the Thai areas of the lower basin has been the highest of all the lower Mekong countries over the past 60 years. There is much current interest in biodiversity and the need to sustain it. Cruising on the mighty Mekong River, one experience out of the many that you can look forward to is bird- watching. Die verschiedenen Völker entlang des Flusslaufs haben unterschiedliche Namen für den Mekong: Tibetisch: Dza Chu ( tib. From the Tibetan Plateau the river runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. New species are still being discovered in the Greater Mekong. The Mekong is one of them. Working to sustain the natural world for the benefit of people and nature. It is 1,380 meters (4,528 ft) long, and was completed in 2000.

The difficulty of navigating the river has meant that it has divided, rather than united, the people who live near it. It swells over four times its smallest size to 14,500 square kilometres at the height of the floods, according to the Mekong River Commission (MRC) - an area bigger than Lebanon. [citation needed], Much of the 8.3 billion tonnes of plastic present on earth[67] makes its way to the oceans. A second time, the river leaves the border and flows east into Laos soon passing the city of Pakse. All river/lake sub-catchments in the Lower Mekong River basin that contain potential KBA trigger species (species meeting the KBA criteria and thresholds) were identified using the species distribution maps assembled. Traditional forms of trade in small boats linking communities continue today, however the river is also becoming an important link in international trade routes, connecting the six Mekong countries to each other, and also to the rest of the world. Broadly, navigation of the river is divided between upper and lower Mekong, with the "upper" part of the river defined as the stretch north of the Khone Falls in southern Laos and the "lower" part as the stretch below these falls. 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. Kuenzer, C. and F. G. Renaud (2012): Climate Change and Environmental Change in River Deltas Globally. Between 1997 and 2009 an incredible 1,376 species were discovered by science across this region alone 1,2,3. In spite of poor fertility, however, agriculture is intensive. [39][40] [12], In Cambodia, wet rice is the main crop and is grown on the flood plains of the Tonle Sap, Mekong, and Bassac (the Mekong delta distributary known as the Hậu in Vietnam) Rivers. If that were not enough, the report’s foreword issues an unmistakable warning. 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. [3] Thailand imports a wide variety of products from China, including vegetables, fruit, agricultural products, and fertilisers. Renaud, F. G. und C. Kuenzer (2012): The Mekong Delta System. But really peculiar is here that the Tonle Sap , who is over months in the dry season feeding the Mekong, in monsoon turns into a sidearm of the Mekong, receiving water from the main stream. Economy. The Mekong River is the second most biodiverse river in the world (after the Amazon River). [39][47][49][50] Fish are the staple of the diet in Laos and Cambodia, with around 80% of the Cambodian population's annual protein intake coming from fish caught in the Mekong River system, with no alternative source to replace it. Key features of flow behaviour are tidal influences and salt water intrusion. The Thai–Lao Friendship Bridge (Thai: สะพานมิตรภาพ ไทย-ลาว; RTGS: saphan mittra phap thai-lao) connects Nong Khai city with Vientiane in Laos. These deflected deposition south-eastwards in the direction of the Cà Mau Peninsula, which is one of the most recent features of the delta. [35], One species of freshwater dolphin, the Irrawaddy dolphin (Orcaella brevirostris), was once common in the whole of the lower Mekong but is now very rare, with only 85 individuals remaining.[38]. In addition, new dams could push endangered aquatic species such as the Mekong giant catfish further to the brink of extinction. Interdisciplinary Analyses of a River Delta. From 8 Ma to the present, however, the contribution from the Three Rivers Area fell to 40%, while that from the Central Highlands rose from 11 to 51%. The Mekong Basin has one of the world's largest and most productive inland fisheries. In the Central Highlands of Vietnam, forest cover was reduced from over 95% in the 1950s to around 50% in the mid-1990s. Interdisciplinary Analyses of a River Delta (= Springer Environmental Science and Engineering). Also, it is a habitat for thousands of plants and animals. The first group are left bank tributaries that drain the high rainfall areas of Laos. Glutinous rice, maize, and cassava are the principal crops. DOI: 10.1080/01431161.2014.890377. DOI: 10.3390/rs5020687. The total economic value of the fishery is between US$3.9 and US$7 billion a year. "China could, in short, use its dams to 'weaponize water'". [58] The plan is split into two phases. Biota estimates for the Greater Mekong Subregion (GMS) include 20,000 plant species, 430 mammals, 1,200 birds, 800 reptiles and amphibians, and an estimated 850 freshwater fish species (excluding euryhaline species mainly found in salt or brackish water, as well as introduced species). DOI: 10.1016/j.rse.2013.05.004. 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%. Between 1973 and 2009, the Greater Mekong subregion (excluding China) lost about a third of its forest cover. 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. [3] [9] Although research projects are currently ongoing, relatively little is known about this species. The magnitude of these earthquakes rarely exceeds 6.5 on the Richter magnitude scale and is unlikely to cause material damage. Laos lies almost entirely within the lower Mekong basin. Many of these species provide direct (e.g. [3], No other river is home to so many species of very large fish. Once believed to have numbered in the thousands, the population began to … This reach includes the hydraulic complexities of the Cambodian floodplain, the Tonle Sap and the Great Lake. The Mekong River is a globally important river system, known for its unique flood pulse hydrology, ecological productivity, and biodiversity. Therein lies the dilemma. [26][page needed]. The biodiversity of the Mekong's fauna and flora is just behind the Amazon basin in South America. Mekong River region is famous for its extremely diverse ecology systems with about 20,000 species of plants, 1,300 species of fish, 1,200 species of birds, 800 species of snakes and frogs and 430 species of mammals. [23] Sediments deposited in the Tonle Sap Great Lake about this time (7.9–7.3 ka) also show indications of marine influence, suggesting a connection to the South China Sea. [3] Wild capture fisheries alone have been valued at US$2 billion a year. The Mun-Chi river system from the right bank in Thailand enters the mainstream within this reach. Of these species, 165 are long distance swimmers and require different habitats throughout their migration and lifecycle. The Mekong River Commission has recorded nearly 500 species of fish in the Mekong river basin, with the majority of them native to Cambodian territories. The Kizuna Bridge is in Cambodia, in the city of Kampong Cham, on the road linking Phnom Penh with the remote provinces of Ratanakiri and Mondolkiri, and Laos. Many of the species in the Mekong are endemic. However, Khong is an archaic word meaning "river", loaned from Austroasiatic languages, such as Vietnamese sông (from *krong) and Mon kruŋ "river", which led to Chinese 江 whose Old Chinese pronunciation has been reconstructed as /*kˤroŋ/[5] and which long served as the proper name of the Yangtze before becoming a generic word for major rivers. The Greater Mekong also hosts a self-cloning skink and a fish with vampire fangs, among many other recently discovered species. Species under threat in the region include the Irrawaddy Dolphin, the Indochinese Tiger, and the Asian Elephant. The catfish, which is the world’s largest freshwater fish that can grow to 3 meters and 350 kilograms, is endemic to the Mekong River, but is facing an increasingly hard time in its natural habitat. The 1,170-metre-long (3,840 ft) bridge opened on 8 April 1994. 2747–2751. We identified 877 fish species in the MRB (not including estuary marine species). European interest was sporadic: the Spanish and Portuguese mounted some missionary and trade expeditions, while the Dutch Gerrit van Wuysthoff led an expedition up the river as far as Vientiane in 1641–42. This extension has since been completed. Saola Douc Langur The reserve protects the headwaters of, from north to south, the Yellow (Huang He), the Yangtze, and the Mekong Rivers. Just after the Amazon River Basin, the Mekong River is often considered to be the second most diverse area on Earth. If that were not enough, the report’s foreword issues an unmistakable warning. [53], The Jinghong Dam, as of January 2020[update] the nearest Chinese dam upstream of the Thai border, has caused huge fluctuations in river levels, affecting people's livelihoods downstream by disrupting the river's natural cycle. [21][22] From 36 to 8 Ma the bulk (76%) of the sediments deposited in the delta came from erosion of the bedrock in the Three Rivers Area. This has implications for the occurrence of drought conditions. The main exports from Thailand are dried longan, fish oil, rubber products, and consumables. New Agreement on Waterway Transportation between Vietnam and Cambodia, signed in Phnom Penh, 17 December 2009. [62] It links Chiang Rai Province, Thailand with Ban Houayxay, Laos. Background: The Lower Mekong river basin supports a high diversity of aquatic species. Among the fish species in the Mekong River, the Mekong giant catfish (scientific name: Pangasianodon gigas) is the biggest. Locals are blaming low water on the newly constructed Xayaburi Dam, as it enters its test phase prior to the start of commercial operation in October 2019. This Irrawaddy dolphin was photographed swimming in the Mekong ... Wild Asian elephants in Kuiburi National Park, Thailand. Table 2 summarises the mean annual flows along the mainstream. It is the world's twelfth longest river and the seventh longest in Asia. Indochinese tiger (Panthera tigris corbetti) is only found in the ... Pseudoryx nghetinhensis - Saola 4 to 5 month old female. World Wildlife Fund has dubbed the Mekong Delta a ‘treasure trove’ of rare creatures teeming with numerous species of plants, lizards, fish, mammals and birds. Many are super-sized. Crested gibbon [12], In a large river system like the Mekong, seasonal flows can be quite variable from year to year. [12] Drought is by far the major hydrological hazard in this region. water purification) benefits to people, supporting local economies and livelihoods across the basin. The mountainous landscape means that only 16% of the country is farmed under lowland terrace or upland shifting cultivation. The Mekong River is the world’s second-most biodiverse river, after the Amazon River, with the largest freshwater fishery . [12], The internal drainage patterns of the Mekong are unusual when compared to those of other large rivers. The population is ranked as critically endangered on the IUCN Red List, the highest international threat ranking for endangered species, and is restricted to a 180 km stretch of the mainstream Mekong River in Cambodia between Kratie and Khone Falls on the border with Laos. The Mekong River Basin, site of the biggest inland fishery in the world, is undergoing massive hydropower development. 687–715. Regional spe-cies richness (Table S1) ranges from 484 species in the Mekong Delta to only 24 species in the Chinese headwaters far north. The cumulative impacts of these activities on the river regime have not been measured. Let’s find out some unique marine animals in this river. The Mekong River is the second most biodiverse river in the world (after the Amazon River). Mature fish migrate up the Mekong River and spawn in April and May at unknown spawning grounds. 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. [3], In Laos, 50 and 100 DWT vessels are operated for regional trade. ► Find out more about these species. The Mekong is really an eruption of wildlife. In: Remote Sensing of Environment 136, pp. The Mekong River produces fish when it flows free and clean electricity when it’s dammed. [24] Although the hydraulic relationships between the Mekong and the Tonle Sap Great Lake systems during the Holocene are not well understood, it is clear that between 9,000 and 7,500 years ago the confluence of the Tonle Sap and the Mekong was in proximity to the South China Sea. Asian elephant [66], Sewage treatment is rudimentary in towns and urban areas throughout much of the Mekong's length, such as Vientiane in Laos. A more outstanding biological treasure than the Amazon river's . At least 329 fish species, nearly 40% of the species identified in the LMB, utilize the 3S Basin. The Mekong Fish Database developed by the Mekong River Commission provides the most comprehensive data source on Mekong fishes, although it does not include any information on species from areas upstream of Yunnan and in Myanmar. After 3.5 ka, however, the delta had built out beyond the embayment and became subject to wave action and marine currents. Agreement between China and Lao PDR on Freight and Passenger Transport along the Lancang–Mekong River, adopted in November 1994. The WWF estimates that there are 20,000 plant species, 430 mammals, 1,200 birds and 800 reptiles and amphibians in the Greater Mekong Sub-region. The drop is due primarily to habitat degradation, bycatch, pollution and climate change. The Mekong Basin can be divided into two parts: the "upper Mekong basin" in Tibet, and the "lower Mekong basin" from Yunnan downstream from China to the South China Sea. Dams are rising all along the Mekong. In Vietnam, since the year 2000 Mỹ Thuận Bridge crosses the first channel—the left, main branch of the Mekong, the Sông Tiền or Tiền Giang—near Vĩnh Long and since 2008 Rạch Miễu Bridge crosses it near Mỹ Tho, between the provinces of Tiền Giang and Bến Tre. Aquatic biodiversity in the Mekong River system is the second highest in the world after the Amazon. 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. "Half a dozen species [out of more than 1,000 — 700 of which are migratory species in the Mekong] seem to have disappeared from the waters where I fish," he says. The seasonal variations in water level directly affect trade in this section of the river. The Khmer empire of Angkor was the last great Indianized state in the region. In: International Journal of Remote Sensing 35 (8), pp. In 2009, 145 species previously unknown to science were described from the region, including 29 fish species, two bird species, 10 reptiles, five mammals, 96 plants, and six amphibians. [3] Fisheries contribute significantly to a diversified livelihood strategy for many people, particularly the poor, who are highly dependent on the river and its resources for their livelihoods. Here we estimate fish biomass and biodiversity losses in numerous damming scenarios using a simple ecological model of fish migration. More giants inhabit this mighty river than any other on Earth. [3] It flows through the Tibetan Autonomous Region and then southeast into Yunnan Province, and then the Three Parallel Rivers Area in the Hengduan Mountains, along with the Yangtze to its east and the Salween River (Nu Jiang in Chinese) to its west. Some of the highlights of the city are its Tropical Plant Institute, which boasts 13,000 species on site, and Manting Park, which has over 1,300 years of history behind it. Threatened species in the Mekong River Ecoregion include mammals such as the iconic Irrawaddy dolphin and gigantic fish like Mekong giant catfish, giant carp, and giant freshwater stingray, all of which can exceed 200 kg in weight. The two-lane, 12-metre-wide (39 ft), 1,600-metre-long (5,200 ft) bridge opened to the public on 9 January 2007. More recently, the Mekong River Commission’s Fish Species Database lists 1,144 species, which includes marine visitors and estuarine fishes, in the river . The flow of the Mekong River is plentiful, cultivating vast wetlands and forests, transporting and supplying construction materials, medicines, and food. The present river morphology of the Mekong Delta developed over the last 6,000 years. In a worst-case scenario, China could well make demands on thirsty downstream countries who would not be able to refuse. The Mekong region is a biodiversity hotspot and its monsoon based annual flood pulse supports the rich biological diversity in the basin. ► Find out more about these species, Leopard The Mekong River provides water, food and energy security for a population of about 70 million people, for most of whom the staple diet is rice, fish, and other aquatic animals. The Mekong basin is not normally considered a seismically active area as much of the basin is underlain by the relatively stable continental block. The name of the rapids means 'where the ghost lost its way'. [27], In 1995, Laos, Thailand, Cambodia, and Vietnam established the Mekong River Commission (MRC) to manage and coordinate the use and care of the Mekong. The Mekong basin is one of the richest areas of biodiversity in the world. [68], A growing number of academics, NGOs, and scientists urge the international community and the Mekong River Commission to put to rest the myth of sustainable hydro power. Although this reach cannot be termed "unspoiled", the hydrological response is perhaps the most natural and undisturbed of all the lower basin. Broadly, there are three types of fish habitats in the Mekong: i) the river, including all the main tributaries, rivers in the major flood zone, and the Tonle Sap, which altogether yield about 30% of wild catch landings; ii) rain-fed wetlands outside the river-floodplain zone, including mainly rice paddies in formerly forested areas and usually inundated to about 50 cm, yielding about 66% of wild catch landings; and iii) large water bodies outside the flood zone, including canals and reservoirs yielding about 4% of wild catch landings.[3]. ► Find out about ongoing new species discoveries in the Greater Mekong The region is home to numerous endangered species, including the Indochinese tiger, the Asian elephant, the Irrawaddy dolphin, and the Mekong giant catfish. The declines of the Murray cod of the Murray-Darling river system in Australia, some sturgeon stocks of Eurasia, the tilapiine species Oreochromis esculentus and Oreochromis variabilisof Lake Victoria, and perhaps the Pacific salmon of the Columbia River are examples of the historical influence of overharvest. Wild capture fisheries play the most important role in supporting livelihoods. [43][44][48] They provide a principal form of income for numerous people and act as a safety net and coping strategy in times of poor agricultural harvests or other difficulties. [42] Hence, the lower Mekong basin yields about 4.5 million tonnes of fish and aquatic products annually. The area is said to be one of the richest areas of biodiversity in the world, second only to the Amazon basin. No other river supports as many huge fish species. Mekong River in Vietnam. Mondulkiri Protected Forest and Phnom Prich Wildlife Sanctuary are ... A male dhole. 7–48. Only 14 have catchment areas that exceed 1,000 km2 (390 sq mi), yet the greatest amount of loss of forest cover in the entire river system per square kilometer has occurred in this region due to heavy unchecked demand for natural resources. The Mekong is reeling from the combined onslaught of climate change, sand-mining, and incessant damming of the river, which combined to help cause the … Narrower and more turbulent sections of water in the upstream parts of the Mekong River, coupled with large annual water level variations continue to present a challenge to navigation. The bridge opened for traffic on 11 December 2001. Flooded forests provide critical terrestrial nutrient inputs and habitat to support aquatic species. This was succeeded by the Khmer culture Chenla state around the 5th century. Port infrastructure is being expanded to accommodate the expected growth in traffic, with new facilities planned for Chiang Saen port. [3], The Mekong is already heavily dammed, with many more dams planned and under construction, mostly for generating hydropower. Kuenzer, C., P. Leinenkugel, M. Vollmuth and S. Dech (2014): Comparing global land-cover products – implications for geoscience applications: an investigation for the trans-boundary Mekong Basin. … … Together, these rivers make up the largest hydrological sub-component of the lower basin. [63][64][65] When drought ends and the inevitable floods begin, the effects of Mekong dams on flood pulse dynamics over the entire Lower Mekong are poorly understood. The 10 Happiest Countries To Live In The World 2019 - Seen as the World’s Safest Countries - Duration: 10:05. To the early European traders, the Mekong River was also known as Mekon River, May-Kiang River and Cambodia River. [2] Its estimated length is 4,350 km (2,703 mi),[2] and it drains an area of 795,000 km2 (307,000 sq mi), discharging 475 km3 (114 cu mi) of water annually. This is also the point of confluence between the Ruak River (which follows the Thai–Myanmar border) and the Mekong. In: Renaud, F. G. and C. Kuenzer (eds. Little is known about these magnificent species of the Greater Mekong region, some attaining five metres in length and over half a ton in weight. The obvious conclusion is that the current model for sharing the Mekong river’s resources is very far from sustainable — and that urgent action is needed to chart a new course for the river, which will underpin the region’s sustainable development rather than undermine it. DOI: 10.1080/01431161.2014.890305. From 1893, the French extended their control of the river into Laos, establishing French Indochina by the first decade of the 20th century. [3], Waterborne trade in the lower Mekong countries of Vietnam and Cambodia has grown significantly, with trends in container traffic at Phnom Penh port and general cargo through Can Tho port both showing steady increases until 2009 when a decrease in cargo volumes can be attributed to the global financial crisis and a subsequent decline in demand for the export of garments to the US. As of 2013, Cambodian volunteers are being trained, with the support of the Office of Weapons Removal and Abatement within the US State Department Bureau of Political-Military Affairs, to conduct underwater explosive removal. , snakes, frogs, bats and 82 plants Mekong 's fauna and flora just.
