Mekong Delta

This article is about the geographical region. For the German heavy metal band, see Mekong Delta (band).
Location of the Mekong Delta region within Vietnam

The Mekong Delta (Vietnamese: Đồng bằng Sông Cửu Long "Nine Dragon river delta"), also known as the Western Region (Vietnamese: Miền Tây or the South-western region (Vietnamese: Tây Nam Bộ) is the region in southwestern Vietnam where the Mekong River approaches and empties into the sea through a network of distributaries. The Mekong delta region encompasses a large portion of southwestern Vietnam of 39,000 square kilometres (15,000 sq mi).[1] The size of the area covered by water depends on the season.

The Mekong Delta has been dubbed as a "biological treasure trove". Over 1,000 animal species were recorded between 1997 and 2007 and new species of plants, fish, lizards, and mammals has been discovered in previously unexplored areas, including the Laotian rock rat, thought to be extinct.[2]

History

A statue of Visnu found at Óc Eo (6–7th century AD).

The Mekong Delta was likely inhabited long since prehistory; the empires of Funan and Chenla maintained a presence in the Mekong Delta for centuries.[3] Archaeological discoveries at Óc Eo and other Funanese sites show that the area was an important part of the Funan kingdom, bustling with trading ports and canals as early as in the first century AD and extensive human settlement in the region may have gone back as far as the 4th century BC. Angkor Borei is a site in the Mekong Delta that existed between 400 BC-500 AD. This site had extensive maritime trade networks throughout Southeast Asia and with India, and is believed to have possibly been the ancient capital to the Kingdom of Funan.[4]

The region was known as Khmer Krom (lower Khmer, or lower Cambodia) to the Khmer Empire, which likely maintained settlements there centuries before its rise in the 11th and 12th centuries.[nb 1] The kingdom of Champa, though mainly based along the coast of modern Central Vietnam, is known to have expanded west into the Mekong Delta, seizing control of Prey Nokor (the precursor to modern-day Ho Chi Minh City) by the end of the 13th century.[nb 2] Author Nghia M. Vo suggests that a Cham presence may indeed have existed in the area prior to Khmer occupation.[nb 3]

Beginning in the 1620s, Khmer king Chey Chettha II (1618–1628) allowed the Vietnamese to settle in the area, and to set up a custom house at Prey Nokor, which they colloquially referred to as Sài Gòn.[5] The increasing waves of Vietnamese settlers which followed overwhelmed the Khmer kingdom—weakened as it was due to war with Thailand—and slowly Vietnamized the area. During the late 17th century, Mạc Cửu, a Chinese anti-Qing general, began to expand Vietnamese and Chinese settlements deeper into Khmer lands, and in 1691, Prey Nokor was occupied by the Vietnamese.

Nguyễn Hữu Cảnh, a Vietnamese noble, was sent by the Nguyễn lords of Huế by sea in 1698 to establish Vietnamese administrative structures in the area.[6] This act formally detached the Mekong Delta from Cambodia, placing the region firmly under Vietnamese administrative control. Cambodia was cut off from access to the South China Sea, and trade through the area was possible only with Vietnamese permission.[3] During the Tây Sơn wars and the subsequent Nguyễn Dynasty, Vietnam's boundaries were pushed as far as the Cape Cà Mau. In 1802 Nguyễn Ánh crowned himself emperor Gia Long and unified all the territories comprising modern Vietnam, including the Mekong Delta.

Upon the conclusion of the Cochinchina Campaign in the 1860s, the area became Cochinchina, France's first colony in Vietnam, and later, part of French Indochina.[7] Beginning during the French colonial period, the French patrolled and fought on the waterways of the Mekong Delta region with their Divisions navales d'assaut (Dinassaut), a tactic which lasted throughout the First Indochina War, and was later employed by the US Navy Mobile Riverine Force.[8] During the Vietnam War—also referred to as the Second Indochina War—the Delta region saw savage fighting between Viet Cong (NLF) guerrillas and units of the United States Navy's swift boats and hovercrafts (PACVs).

Following independence from France, the Mekong Delta was part of the Republic of Vietnam and eventually the country of Vietnam. In the 1970s, the Khmer Rouge regime attacked Vietnam in an attempt to reconquer the Delta region. This campaign precipitated the Vietnamese invasion of Cambodia and subsequent downfall of the Khmer Rouge.

Geography

Mekong River Delta from space, February 1996

The Mekong Delta, as a region, lies immediately to the west of Ho Chi Minh City (also called Saigon by locals), roughly forming a triangle stretching from Mỹ Tho in the east to Châu Đốc and Hà Tiên in the northwest, down to Cà Mau at the southernmost tip of Vietnam, and including the island of Phú Quốc.

The Mekong Delta region of Vietnam displays a variety of physical landscapes, but is dominated by flat flood plains in the south, with a few hills in the north and west. This diversity of terrain was largely the product of tectonic uplift and folding brought about by the collision of the Indian and Eurasian tectonic plates about 50 million years ago. The soil of the lower Delta consists mainly of sediment from the Mekong and its tributaries, deposited over thousands of years as the river changed its course due to the flatness of the low-lying terrain.[9]

The present Mekong Delta system has two major distributary channels, both discharging directly into the South China Sea. The Holocene history of the Mekong Delta shows delta progradation of about 200 km during the last 6 kyr. During the Middle Holocene the Mekong River was discharging waters into both the South China Sea and the Gulf of Thailand. The water entering the Gulf of Thailand was flowing via a palaeochannel located within the western part of the delta; north of the Camau Peninsula.[10] Upper Pleistocene prodeltaic and delta front sediments interpreted as the deposits of the palaeo-Mekong River where reported from central basin of the Gulf of Thailand[11]

The Mekong Delta is the region with the smallest forest area in Vietnam. 300,000 hectares (740,000 acres) or 7.7% of the total area are forested as of 2011. The only provinces with large forests are Cà Mau Province and Kiên Giang Province, together accounting for two thirds of the region's forest area, while forests cover less than 5% of the area of all of the other eight provinces and cities.[12]

Climate change concerns

Being a low-lying coastal region, the Mekong Delta is particularly susceptible to floods resulting from rises in sea level due to climate change. The Climate Change Research Institute at Cần Thơ University, in studying the possible consequences of climate change, has predicted that, besides suffering from drought brought on by seasonal decrease in rainfall, many provinces in the Mekong Delta will be flooded by the year 2030. The most serious cases are predicted to be the provinces of Bến Tre and Long An, of which 51% and 49%, respectively, are expected to be flooded if sea levels rise by one meter.[13] Another problem caused by climate change is the increasing soil salinity near the coasts. Bến Tre Province is planning to reforest coastal regions to counter this trend.[14]

Demographics

Mekong Delta

The inhabitants of the Mekong Delta region are predominantly ethnic Viet. The region, formerly part of the Khmer Empire, is also home to the largest population of Khmers outside of the modern borders of Cambodia. The Khmer minority population live primarily in the Trà Vinh, Sóc Trăng, and Muslim Chăm in Tan Chau, An Giang provinces. There are also sizeable Hoa (ethnic Chinese) populations in the Kiên Giang, and Trà Vinh provinces. The region had a population of 17.33 million people in 2011.[12]

The population of the Mekong Delta has been growing relatively slowly in recent years, mainly due to out-migration. The region's population only increased by 471,600 people between 2005 and 2011, while 166,400 people migrated out in 2011 alone. Together with the central coast regions, it has one of the slowest growing populations in country. Population growth rates have been between 0.3% and 0.5% between 2008 and 2011, while they have been over 2% in the neighbouring southeastern region.[12] Net migration has been negative in all of these years. The region also has a relatively low fertility rate, at 1.8 children per woman in 2010 and 2011, down from 2.0 in 2005.[12]

Economy

The Mekong Delta is by far Vietnam's most productive region in agriculture and aquaculture, while its role in industry and foreign direct investment is much smaller.

Agriculture

2.6 million ha in the Mekong Delta are used for agriculture, which is one fourth of Vietnam's total.[12] Due to its mostly flat terrain and few forested areas (except for Cà Mau Province), almost two thirds (64.5%) of the region's land can be used for agriculture. The share of agricultural land exceeds 80% in Cần Thơ and neighbouring Hậu Giang Province and is below 50% only in Cà Mau Province (32%) and Bạc Liêu Province (42%).[12] The region's land used for growing cereals makes up 47% of the national total, more than northern and central Vietnam combined. Most of this is used for rice cultivation.

Rice output in 2011 was 23,186,000t, 54.8% of Vietnam's total output. The strongest producers are Kiên Giang Province, An Giang Province, and Đồng Tháp Province, producing over 3 million tonnes each and almost 11 million tonnes together. Any two of these provinces produce more than the entire Red River Delta.[12] Only three provinces produce less than 1 million tonnes of rice (Bạc Liêu Province, Cà Mau Province, Bến Tre Province).[12]

Fishery

The Mekong Delta is also Vietnam's most important fishing region. It has almost half of Vietnam's capacity of offshore fishing vessels (mostly in Kien Gian with almost 1/4, Bến Tre, Cà Mau, Tiền Giang, Bạc Liêu). Fishery output was at 3.168 million tons (58.3% of Vietnam) and has experienced rapid growth from 1.84mt in 2005.[12] All of Vietnam's largest fishery producers with over 300kt of output are in the Mekong Delta: Kiên Giang, Cà Mau, Đồng Tháp, An Giang, and Bến Tre.[12]

Despite the region's large offshore fishing fleet, 2/3 (2.13 million tonnes out of Vietnam's total of 2.93) of fishery output actually comes from aquaculture.[12]

Industry and FDI

The Mekong Delta is not strongly industrialized, but is still the third out of seven regions in terms of industrial gross output. The region's industry accounts for 10% of Vietnam's total as of 2011.[12] Almost half of the region's industrial production is concentrated in Cần Thơ, Long An Province and Cà Mau Province. Cần Thơ is the economic center of the region and more industrialized than the other provinces. Long An has been the only province of the region to attract part of the manufacturing booming around Ho Chi Minh City and is seen by other provinces as an example of successful FDI attraction.[15] Cà Mau Province is home to a large industrial zone including power plants and a fertiliser factory.[16]

Accumulated foreign direct investment in the Mekong Delta until 2011 was $10.257bn.[12] It has been highly concentrated in a few provinces, led by Long An and Kiên Giang with over $3bn each, Tiền Giang and Cần Thơ (around 850m), Cà Mau (780m) and Hậu Giang (673m), while the other provinces have received less than 200m each.[12] In general, the performance of the region in attracting FDI is evaluated as unsatisfactory by local analysts and policymakers.[15] Companies from Ho Chi Minh City have also invested heavily in the region. Their investment from 2000 to June 2011 accounted for 199 trillion VND (almost $10bn).[17]

Infrastructure

The construction of the Cần Thơ Bridge, a cable-stayed bridge over the largest distributary of the Mekong River, was completed on April 12, 2010, three years after a collapse that killed 54 and injured nearly 100 workers. The bridge replaces the ferry system that currently runs along National Route 1A, and links Vĩnh Long Province and Cần Thơ city. The cost of construction is estimated to be 4.842 trillion Vietnamese đồng (approximately 342.6 million United States dollars), making it the most expensive bridge in Vietnam.[18]

Culture

Life in the Mekong Delta revolves much around the river, and many of the villages are often accessible by rivers and canals rather than by road.

The region is home to cải lương, a form of Kinh/Vietnamese folk opera.

Literature and movies

Several movies have been filmed in the Mekong Delta and depict the culture of the region. They include The Buffalo Boy and The Floating Lives.

In the movie Apocalypse Now, Lt. Col. Kilgore captures this location for the American soldiers to surf (due to its 6-foot peak), justifying it with the famous line, "Charlie don't surf".

Nguyễn Ngọc Tư, an author from Cà Mau Province, has written many popular books about life in the Mekong Delta.
