Consequently, although the Mun and Chi basins drain 15% of the entire Mekong basin, they only contribute 6% of the average annual flow. Sandy and saline soils are the most common soil types, which makes much of the land unsuitable for wet rice cultivation. In spite of poor fertility, however, agriculture is intensive. Glutinous rice, maize, and cassava are

10125-522: The expansion of Austroasiatic and Austronesian groups. Distinctive Basal-East Asian (East-Eurasian) ancestry was recently found to have originated in Mainland Southeast Asia at ~50,000BC, and expanded through multiple migration waves southwards and northwards respectively. Geneflow of East Asian-related ancestry into Maritime Southeast Asia and Oceania could be estimated to ~25,000BC (possibly also earlier). The pre-Neolithic Papuan-related populations of Maritime Southeast Asia were largely replaced by
10260-411: The expansion of various East Asian-related populations, beginning about 50,000BC to 25,000BC years ago from Mainland Southeast Asia. The remainders, known as Negritos, form small minority groups in geographically isolated regions. Southeast Asia was dominated by East Asian-related ancestry already in 15,000BC, predating the expansion of Austroasiatic and Austronesian peoples . In the late Neolithic ,
10395-590: The fifth century CE, trade networking between East and West was concentrated in the maritime route. Foreign traders were starting to use new routes such as Malacca and Sunda Strait due to the development of maritime Southeast Asia. This change resulted in the decline of Funan, while new maritime powers such as Srivijaya , Tarumanagara , and Mataram emerged. Srivijaya especially became the dominant maritime power for more than 5 centuries, controlling both Strait of Malacca and Sunda Strait . This dominance started to decline when Srivijaya were invaded by Chola Empire ,
10530-476: The flow of the Tonlé Sap River causing it to flow back into the lake. The lake expands from 2500 km to more than 16,000 km creating an enormous wetland area. This wetland area supports a tremendous amount of biodiversity including plants, reptiles, mammals, birds and other animals. Many of these are known to be rare or endangered. These wetlands are also an important breeding area for fish from
10665-597: The former western colonies under the concept of " Greater East Asia Co-Prosperity Sphere ". However, the Shōwa occupation regime committed violent actions against civilians such as live human experimentation, sexual slavery under the brutal " comfort women " system, the Manila massacre and the implementation of a system of forced labour , such as the one involving four to ten million romusha in Indonesia. A later UN report stated that four million people died in Indonesia as
10800-510: The freshwater fish in the river basin are cypriniforms (377 species) and catfish (92 species). Southeast Asia Southeast Asia is the geographical southeastern region of Asia , consisting of the regions that are situated south of China , east of the Indian subcontinent , and northwest of the Australian mainland , which is part of Oceania . Southeast Asia is bordered to
10935-497: The ghost lost its way'. It then turns east into the interior of Laos, flowing first east and then south for some 400 km (250 mi) before meeting the border with Thailand again. Once more, it defines the Laos-Thailand border for some 850 km (530 mi) as it flows first east, passing the capital of Laos, Vientiane , then turns south. A second time, the river leaves the border and flows east into Laos soon passing
11070-675: The government of Cambodia to fulfil 3 key functions. These are: The Biosphere has been divided into 3 core areas for protection. These are; Prek Toal in Battambang Province , Boeng Tonle Chhmar in Kampong Thom Province and Stoeng Sen also in Kompong Thom. Boeng Tonle Chhmar has been selected as a Ramsar Convention site, which designates wetlands of international importance. The core areas function similar to national park areas and cover 42,300 ha. including
11205-528: The high rainfall areas of Laos. The second group are those on the right bank, mainly the Mun and Chi Rivers, that drain a large part of northeast Thailand. Laos lies almost entirely within the lower Mekong basin. Its climate, landscape and land use are the major factors shaping the hydrology of the river. The mountainous landscape means that only 16% of the country is farmed under lowland terrace or upland shifting cultivation . With upland shifting agriculture (slash and burn), soils recover within 10 to 20 years but
11340-750: The hydrological impacts of land cover changes induced by the Vietnam War were quantified in two sub-catchments of the lower Mekong River basin. 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. On the Khorat Plateau , which includes the Mun and Chi tributary systems, forest cover was reduced from 42% in 1961 to 13% in 1993. Although this part of northeast Thailand has an annual rainfall of more than 1,000 mm (40 in),
11475-437: The hydrological response is perhaps the most natural and undisturbed of all the lower basin. Many hydrological aspects of the lower basin start to change rapidly at the downstream boundary of this reach. On 19 July 2019 this reach of the river dropped to its lowest level in a century. Officials are particularly concerned as July is in the wet season, when mainstream flows are abundant historically. Locals are blaming low water on
11610-461: The island of New Guinea ; it is the only place where ice glaciers can be found in Southeast Asia. The highest mountain in Southeast Asia is Hkakabo Razi at 5,967 metres (19,577 feet) and can be found in northern Burma sharing the same range of its parent peak, Mount Everest . The South China Sea is the major body of water within Southeast Asia. The Philippines, Vietnam, Malaysia, Brunei, Indonesia, and Singapore, have integral rivers that flow into
11745-550: The lake and Mekong River. Both Siamese crocodiles (Crocodylus siamensis) and saltwater crocodiles (Crocodylus porosus) once occurred side-by-side in the lake, and there is thought to be inter-species breeding amongst the crocodiles found in the floating farms on the western part of the Lake in and around Prek Toal. In 2001, the Tonlé Sap Biosphere Reserve (TSBR) of Cambodia was established by Royal Decree of
11880-479: The lands they conquered, and attempted to spread European institutions to the region. Several Southeast Asian countries were also briefly occupied by the Japanese Empire during World War II . The aftermath of World War II saw most of the region decolonised. Today, Southeast Asia is predominantly governed by independent states. The region, together with part of South Asia, was well known by Europeans as
12015-472: The largest empire to ever exist in Southeast Asian history. By the 15th century CE however, Majapahit's influence began to wane due to many war of successions it experienced and the rise of new Islamic states such as Samudera Pasai and Malacca Sultanate around the strategic Strait of Malacca . Majapahit then collapsed around 1500. It was the last major Hindu kingdom and the last regional power in
12150-437: The lower basin from Yunnan make up about 15% of the wet season flow at Kratie . This rises to 40% during the dry season, even this far downstream. During the wet season, the proportion of average flow coming from Yunnan rapidly decreases downstream of Chiang Saen, from 70% to less than 20% at Kratie. The dry season contribution from Yunnan is much more significant. The major portion of the balance comes from Laos, which points to
12285-583: The lower basin. Over 25% of the mean annual flow volume to the mainstream at Kratie comes from these three river basins. They are the key element in the hydrology of this part of the system, especially to the Tonle Sap flow reversal. Reach 5: Kratie to Phnom Penh . This reach includes the hydraulic complexities of the Cambodian floodplain, the Tonle Sap and the Great Lake. By this stage, over 95% of
12420-611: The newly constructed Xayaburi Dam , as it enters its test phase prior to the start of commercial operation in October 2019. Reach 3: Vientiane and Nong Khai to Pakse . The boundary between Reach 2 and 3 is where the Mekong hydrology starts to change. Reach 2 is dominated in both wet and dry seasons by the Yunnan Component. Reach 3 is increasingly influenced by contributions from the large left bank tributaries in Laos, namely
12555-866: The north by East Asia , to the west by South Asia and the Bay of Bengal , to the east by Oceania and the Pacific Ocean , and to the south by Australia and the Indian Ocean . Apart from the British Indian Ocean Territory and two out of 26 atolls of the Maldives in South Asia, Maritime Southeast Asia is the only other subregion of Asia that lies partly within the Southern Hemisphere . Mainland Southeast Asia
12690-667: The ocean. Magellan's voyage records how much more manoeuvrable their vessels were, as compared to the European ships. A slave from the Sulu Sea was believed to have been used in the Magellan expedition as a translator. Studies presented by the Human Genome Organisation (HUGO) through genetic studies of the various peoples of Asia show empirically that there was a single migration event from Africa, whereby
12825-727: The present, however, the contribution from the Three Rivers Area fell to 40%, while that from the Central Highlands rose from 11 to 51%. One of the most striking conclusions of provenance studies is the small contribution of sediment from the other parts of the Mekong basin, notably the Khorat Plateau, the uplands of northern Laos and northern Thailand, and the mountain ranges south of the Three Rivers area. The last glacial period came to an abrupt end about 19,000 years ago (19 ka ) when sea levels rose rapidly, reaching
12960-436: The principal crops. Drought is by far the major hydrological hazard in this region. As the Mekong enters Cambodia, over 95% of its flows have already joined the river. From here on downstream the terrain is flat and water levels rather than flow volumes determine the movement of water across the landscape. The seasonal cycle of changing water levels at Phnom Penh results in the unique "flow reversal" of water into and out of
13095-796: The principal left bank tributaries enter the mainstream, mainly the Nam Ngum and Nam Theun. The flow level falls again, even with the right bank entry of the Mun-Chi system from Thailand. Although the Mun–Chi basin drains 20% of the lower system, average annual runoff is only 250 mm (10 in). Runoff in the mainstream increases again with the entry from the left bank of the Se Kong from southern Laos and Se San and Sre Pok from Vietnam and Cambodia. Table 2: Lower Mekong Mainstream annual flow (1960 to 2004) at selected sites. Flows at Chiang Saen entering
13230-462: The proper name of the Yangtze before becoming a generic word for major rivers. To the early European traders, the Mekong River was also known as Mekon River , May-Kiang River and Cambodia River . The local names for the river include: The Mekong rises as the Za Qu ( Tibetan : རྫ་ཆུ་ , Wylie : rDza chu , ZYPY : Za qu ; Chinese : 扎曲 ; pinyin : Zā Qū ) and soon becomes known as
13365-645: The region and Sri Lanka . Buddhism later established a strong presence in Funan region in the fifth century. In present-day mainland Southeast Asia, Theravada is still the dominant branch of Buddhism, practised by the Thai, Burmese, and Cambodian Buddhists. This branch was fused with the Hindu-influenced Khmer culture. Mahayana Buddhism established presence in Maritime Southeast Asia, brought by Chinese monks during their transit in
13500-407: The region and made contacts with local courts. Local rulers converted to Hinduism or Buddhism and adopted Indian religious traditions to reinforce their legitimacy, elevate ritual status above their fellow chief counterparts and facilitate trade with South Asian states. They periodically invited Indian Brahmins into their realms and began a gradual process of Indianisation in the region. Shaivism
13635-423: The region as Islam provided a positive force among the ruling and trading classes. Gujarati Muslims played a pivotal role in establishing Islam in Southeast Asia. Trade among Southeast Asian countries has a long tradition. The consequences of colonial rule, struggle for independence, and in some cases war influenced the economic attitudes and policies of each country. From 111 BC to 938 AD northern Vietnam
13770-523: The region before the arrival of the Europeans. Islam began to make contacts with Southeast Asia in the eighth-century CE, when the Umayyads established trade with the region via sea routes. However its spread into the region happened centuries later. In the 11th century, a turbulent period occurred in the history of Maritime Southeast Asia . The Indian Chola navy crossed the ocean and attacked
13905-523: The region came under contact with the Indian subcontinent c. 400 BCE , it began a gradual process of Indianisation where Indian ideas such as religions, cultures, architectures, and political administrations were brought by traders and religious figures and adopted by local rulers. In turn, Indian Brahmins and monks were invited by local rulers to live in their realms and help transforming local polities to become more Indianised, blending Indian and indigenous traditions. Sanskrit and Pali became
14040-644: The region en route to Nalanda . It is still the dominant branch of Buddhism practised by Indonesian and Malaysian Buddhists. The spread of these two Indian religions confined the adherents of Southeast Asian indigenous beliefs into remote inland areas. The Maluku Islands and New Guinea were never Indianised and its native people were predominantly animists until the 15th century when Islam began to spread in those areas. While in Vietnam, Buddhism never managed to develop strong institutional networks due to strong Chinese influence. In present-day Southeast Asia, Vietnam
14175-635: The region were the Pyu city-states that already existed circa second century BCE, located in inland Myanmar. It served as an overland trading hub between India and China. Theravada Buddhism was the predominant religion of these city states, while the presence of other Indian religions such as Mahayana Buddhism and Hinduism were also widespread. In the first century, the Funan states centered in Mekong Delta were established, encompassed modern-day Cambodia, southern Vietnam, Laos, and eastern Thailand. It became
14310-553: The region, specifically, the Philippines. East Timor and the eastern half of Indonesia (east of the Wallace Line in the region of Wallacea ) are considered to be geographically associated with Oceania due to their distinctive faunal features. Geologically, the island of New Guinea and its surrounding islands are considered as parts of the Australian continent , connected via the Sahul Shelf . Both Christmas Island and
14445-487: The rest of Indonesia , Malaysia , southern Vietnam , and Palau by 1000 BC. They often settled along coastal areas, replacing and assimilating the diverse preexisting peoples. The Austronesian peoples of Southeast Asia have been seafarers for thousands of years. They spread eastwards to Micronesia and Polynesia , as well as westwards to Madagascar , becoming the ancestors of modern-day Malagasy , Micronesians , Melanesians , and Polynesians . Passage through
14580-457: The result of the Chola expeditions. As Srivijaya influence in the region declined, The Hindu Khmer Empire experienced a golden age during the 11th to 13th century CE. The empire's capital Angkor hosts majestic monuments—such as Angkor Wat and Bayon . Satellite imaging has revealed that Angkor, during its peak, was the largest pre-industrial urban centre in the world. The Champa civilisation
14715-495: The river as far as Vientiane in 1641–42. The French invaded the region in the mid-19th century, capturing Saigon in 1861, and establishing a protectorate over Cambodia in 1863. The first systematic European exploration began with the French Mekong Expedition led by Ernest Doudard de Lagrée and Francis Garnier , which ascended the river from its mouth to Yunnan between 1866 and 1868. Their chief finding
14850-448: The river develops alluvial channels that are free of control exerted by the underlying bedrock. The Mekong basin is not normally considered a seismically active area as much of the basin is underlain by the relatively stable continental block. Nonetheless, the parts of the basin in northern Laos , northern Thailand , Myanmar and China do experience frequent earthquakes and tremors. The magnitude of these earthquakes rarely exceeds 6.5 on
14985-480: The river flows for a further 2,600 km (1,600 mi) through Laos, Thailand, and Cambodia before entering the South China Sea via a complex delta system in Vietnam . The upper basin makes up 24% of the total area and contributes 15–20% of the water that flows into the Mekong River. The catchment here is steep and narrow with Soil erosion being a major problem and as a result of this, approximately 50% of
15120-409: The river landscape is flat. Small changes in water level determine the direction of water movement, including the large-scale reversal of flow into and out of the Tonle Sap basin from the Mekong River. The Mekong Delta in Vietnam is farmed intensively and has little natural vegetation left. Forest cover is less than 10%. In the Central Highlands of Vietnam, forest cover was reduced from over 95% in
15255-601: The river's ecosystem , including the exacerbation of drought . The Mekong was originally called Mae Nam Khong from a contracted form of Tai shortened to Mae Khong . In Thai and Lao, Mae Nam ("Mother of Water[s]") is used for large rivers and Khong is the proper name referred to as "River Khong". 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/ and which long served as
15390-477: The sediment in the river comes from the upper basin. In Yunnan Province in China, the river and its tributaries are confined by narrow, deep gorges. The tributary river systems in this part of the basin are small. Only 14 have catchment areas that exceed 1,000 km (400 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. In
15525-507: The south of Yunnan, in Simao and Xishuangbanna Prefectures, the river changes as the valley opens out, the floodplain becomes wider, and the river becomes wider and slower. Major tributary systems develop in the lower basin. These systems can be separated into two groups: tributaries that contribute to the major wet season flows, and tributaries that drain low relief regions of lower rainfall. The first group are left bank tributaries that drain
15660-633: 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. The many maps of the river basin produced throughout recorded history reflect the region's changing human geography and politics. In 1995, Laos, Thailand, Cambodia, and Vietnam established the Mekong River Commission (MRC) to manage and coordinate
15795-415: The term also refers to the much larger area of those three countries that was notorious as a drug producing region. From the Golden Triangle tripoint, the Mekong turns southeast to briefly form the border of Laos with Thailand. Khon Pi Long is a series of rapids along a 1.6 km (1.0 mi) section of the Mekong River dividing Chiang Rai and Bokeo Province in Laos. The name of the rapids means 'where
15930-492: The term became more restricted to territories of the former French Indochina (Cambodia, Laos, and Vietnam). The maritime section of Southeast Asia is also known as the Malay Archipelago , a term derived from the European concept of a Malay race . Another term for Maritime Southeast Asia is Insulindia (Indian Islands), used to describe the region between Indochina and Australasia . The term "Southeast Asia"
16065-572: The total flow has entered the Mekong system. The focus turns from hydrology and water discharge to the assessment of water level, over- bank storage and flooding and the hydrodynamics that determine the timing, duration and volume of the seasonal flow reversal into and out of the Great Lake. Reach 6: Phnom Penh to the South China Sea . Here the mainstream divides into a complex and increasingly controlled and artificial system of branches and canals. Key features of flow behaviour are tidal influences and salt water intrusion. Every year, 35–50% of this reach
16200-478: The underlying geological structure is fairly homogeneous and stable, exerting little or no control on river morphology . In marked contrast, the tributary networks of the Salween , Yangtze , and particularly the Mekong, are complex with different sub-basins often exhibiting different, and distinct, drainage patterns. These complex drainage systems have developed in a setting where the underlying geological structure
16335-687: The use and care of the Mekong. In 1996 China and Myanmar became "dialogue partners" of the MRC and the six countries now work together in a cooperative framework. In 2000, the governments of China, Laos, Thailand and Myanmar signed a Agreement on Commercial Navigation on Lancang-Mekong River among the Governments of the People's Republic of China, the Lao People's Democratic Republic, the Union of Myanmar and
16470-419: The vegetation does not. Shifting cultivation is common in the uplands of northern Laos and is reported to account for as much as 27% of the total land under rice cultivation. As elsewhere in the basin, forest cover has been steadily reduced during the last three decades by shifting agriculture and permanent agriculture. The cumulative impacts of these activities on the river regime have not been measured. However,
16605-464: 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). Besides being a danger for fishermen, unexploded ordnance also creates problems for bridge and irrigation systems construction. As of 2013, Cambodian volunteers are being trained, with
16740-463: The west and from the east. Regular trade between the ships sailing east from the Indian Ocean and south from mainland Asia provided goods in return for natural products, such as honey and hornbill beaks from the islands of the archipelago. Before the 18th and 19th centuries, the Europeans mostly were interested in expanding trade links. For the majority of the populations in each country, there
16875-533: The younger population of China. Solheim and others have shown evidence for a Nusantao maritime trading network ranging from Vietnam to the rest of the archipelago as early as 5000 BC to 1 AD. The Bronze Age Dong Son culture flourished in Northern Vietnam from about 1000 BC to 1 BC. Its influence spread to other parts Southeast Asia. The region entered the Iron Age era in 500 BC, when iron
17010-509: Was already inhabited by Homo erectus from approximately 1,500,000 years ago during the Middle Pleistocene age. Distinct Homo sapiens groups, ancestral to Eastern non-African (related to East Asians as well as Papuans) populations, reached the region by between 50,000BC to 70,000BC, with some arguing earlier. Rock art (parietal art) dating from 40,000 years ago (which is currently the world's oldest) has been discovered in
17145-598: Was comparatively little interaction with Europeans and traditional social routines and relationships continued. For most, a life with subsistence-level agriculture, fishing and, in less developed civilisations, hunting and gathering was still hard. Europeans brought Christianity allowing Christian missionaries to become widespread. Thailand also allowed Western scientists to enter its country to develop its own education system as well as start sending royal members and Thai scholars to get higher education from Europe and Russia. During World War II, Imperial Japan invaded most of
17280-481: Was constructed largely through fluvial and tidal processes. At this time the delta was advancing at a rate of 17 to 18 m (56 to 59 ft) per year. After 3.5 ka, however, the delta had built out beyond the embayment and became subject to wave action and marine currents. These deflected deposition south-eastwards in the direction of the Cà Mau Peninsula , which is one of the most recent features of
17415-690: Was first used in 1839 by American pastor Howard Malcolm in his book Travels in South-Eastern Asia . Malcolm only included the Mainland section and excluded the Maritime section in his definition of Southeast Asia. The term was officially used in the midst of World War II by the Allies , through the formation of South East Asia Command (SEAC) in 1943. SEAC popularised the use of the term "Southeast Asia", although what constituted Southeast Asia
17550-459: Was forged also in northern Vietnam still under Dong Son, due to its frequent interactions with neighbouring China. Most Southeast Asian people were originally animist , engaged in ancestors, nature, and spirits worship. These belief systems were later supplanted by Hinduism and Buddhism after the region, especially coastal areas, came under contact with Indian subcontinent during the first century. Indian Brahmins and traders brought Hinduism to
17685-548: Was located in what is today central Vietnam, and was a highly Indianised Hindu Kingdom. The Vietnamese launched a massive conquest against the Cham people during the 1471 Vietnamese invasion of Champa , ransacking and burning Champa, slaughtering thousands of Cham people, and forcibly assimilating them into Vietnamese culture. During the 13th century CE, the region experienced Mongol invasions , affected areas such as Vietnamese coast, inland Burma and Java . In 1258, 1285 and 1287,
17820-414: Was not fixed; for example, SEAC excluded the Philippines and a large part of Indonesia while including Ceylon . However, by the late 1970s, a roughly standard usage of the term "Southeast Asia" and the territories it encompasses had emerged. Although from a cultural or linguistic perspective the definitions of "Southeast Asia" may vary, the most common definitions nowadays include the area represented by
17955-542: Was that the Mekong had too many falls and rapids to ever be useful for navigation . The river's source was found by Pyotr Kuzmich Kozlov in 1900. From 1893, the French extended their control of the river into Laos, establishing French Indochina by the first decade of the 20th century. This lasted until the First and Second Indochina Wars expelled French from its former colony and defeated US-supported governments. During
18090-436: Was the dominant religious tradition of many southern Indian Hindu kingdoms during the first century. It then spread into Southeast Asia via Bay of Bengal , Indochina, then Malay Archipelago, leading to thousands of Shiva temples on the islands of Indonesia as well as Cambodia and Vietnam, co-evolving with Buddhism in the region. Theravada Buddhism entered the region during the third century, via maritime trade routes between
18225-508: Was under Chinese rule. Vietnam was successfully governed by a series of Chinese dynasties including the Han , Eastern Han , Eastern Wu , Cao Wei , Jin , Liu Song , Southern Qi , Liang , Sui , Tang , and Southern Han . Records from Magellan's voyage show that Brunei possessed more cannon than European ships, so the Chinese must have been trading with them. Malaysian legend has it that
