Vietnam - Land and Resources

Shaped like an enormous letter S, Vietnam extends more than 1,500 km (1,000 mi) from China in the north to the Gulf of Thailand in the south. At its narrowest, just north of the port city of Da Nang, the distance between the sea and the country’s western border is less than 50 km (30 mi). Vietnam’s total area is 331,690 sq km (128,066 sq mi).



Natural Regions

Vietnam has four major geographic regions. The country’s northernmost section consists of a tangled mass of rugged and heavily forested mountains that extend into Vietnam from China’s Yunnan Plateau. In Vietnam, these mountains attain a maximum elevation of 3,143 m (10,312 ft) at Fan Si Pan, the country’s highest point. To the east and southeast of these mountainous highlands is the Red River Delta, a triangular-shaped alluvial plain that stretches along the Gulf of Tonkin, an arm of the South China Sea. The Truong Son (Annam Highlands) lies to the south of the delta and forms the backbone of Vietnam. Also in this region are the Central Highlands, a vast upland plateau situated between the Cambodian border and the South China Sea. Vietnam’s fourth and southernmost region is the Mekong Delta. This region is a fertile area of marshy flatland that stretches from the southern edge of the Central Highlands in the north to the mangrove swamps of the Ca Mau peninsula in the south.

Rivers

Vietnam’s two major rivers are the Red River in the north and the Mekong River in the south, both of which are navigable for their entire lengths within Vietnam. The Red River flows almost directly southeast from southern China into Vietnam’s northwestern highlands. The Mekong follows an irregular path across Southeast Asia to its mouth at the South China Sea. Farming in much of the Mekong Delta was once impossible because salt water from the South China Sea would periodically cover the low-lying land. To combat this problem, the French installed dikes during the 20th century. Today, an intricate system of dikes and canals helps prevent flooding of the Mekong and Red River deltas. Among Vietnam’s noteworthy smaller rivers are the Huong River (Perfume River) at Hue and the Ka Long O River near Vinh.

Coastline

Vietnam’s coastline extends 3,440 km (2,140 mi) from the Chinese border in the north to the frontier with Cambodia in the Gulf of Thailand. In some areas, such as east of the Central Highlands and north of the Red River Delta, the mountains extend directly into the sea. This creates a number of protected harbors suitable for shipping, including those of the port cities of Da Nang, Qui Nhon, and Nha Trang. The mountains also form a picturesque backdrop, and beaches at Da Nang and Nha Trang are among the most popular resort areas in the country. The remaining coastal areas are flatlands, created by the deposits of alluvial soils by rivers. Over time, this deposition process creates triangular, flat deltas, notably the Red and Mekong deltas.

Plant and Animal Life

Many plant and animal species thrive in Vietnam’s warm, rainy climate. Mountain forests are typically dense, consisting of a wide variety of evergreens and rain forest vegetation. Upland farmers periodically clear lands for cultivation, which causes some deforestation, although this is not nearly as serious a problem as in other areas of Southeast Asia. During the Vietnam War (1959-1975) heavy bombing cleared some areas of foliage, but plant life in these areas has gradually begun to recover. In the country’s warmest zones, farmers have widely planted the hillsides and plateau regions with cash crops such as coffee, tea, and rubber. Most lowland areas and some upland valleys are planted with wet rice, although other useful crops include bananas, coconuts, papaya, and bamboo. Dense mangrove swamps cover the lowland areas along the southern coast of the Mekong Delta and on the Ca Mau peninsula.

Vietnam’s forests are inhabited by many large mammals, including elephants, deer, bears, tigers, and leopards. Smaller animals, such as monkeys, hares, squirrels, and otters, are also found in considerable numbers throughout the country. In recent years, scientists have identified several previously unknown species of animal life in the Truong Son, including the endangered sao la, a cattlelike animal. Many species of birds and reptiles, including crocodiles, snakes, and lizards, also thrive in Vietnam.

Natural Resources

Vietnam’s most valuable natural resource is its land, particularly the fertile, alluvial soils in the Red and Mekong deltas. Some 23 percent of the land is currently being cultivated.

Vietnam has some valuable mineral resources, including gold, iron, tin, zinc, phosphate, chromite, apatite, and anthracite coal. Most deposits are located in the northern part of the country. Few attempts were made to extract these minerals until the French takeover of Vietnam at the end of the 19th century. The French opened coal mines, principally along the coast directly east of Haiphong. They also established a phosphate factory on the Paracel Islands, located in the South China Sea.

Since reunification, the Communist government has sought to increase exploitation of Vietnam’s natural mineral resources but has had only modest success so far. Extraction of oil deposits in the South China Sea began in the mid-1980s. In the mid-1990s oil production was sufficient to meet domestic needs, while also providing an important source of export earnings.

Climate

Vietnam’s climate is generally hot and humid. In central and southern Vietnam, seasonal variations are slight and marked only by a dry and a wet period. The average daily temperatures in the Mekong Delta range from 17° to 34° C (63° to 93° F) in January and from 22° to 33° C (72° to 91° F) in July. Along the central coast, temperatures range from 18° to 28° C (64° to 83° F) in January and from 24° to 37° C (76° to 99° F) in July. The northern plains experience greater seasonal variations and generally have cooler nighttime temperatures. The average daily temperatures at Hanoi, for example, range from 13° to 20° C (56° to 68° F) in January and from 25° to 33° C (78° to 91° F) in July.

In general, rainfall is plentiful throughout the country, although most precipitation in southern and central Vietnam occurs during the summer months when monsoon winds sweep in from the sea. The Mekong Delta has the longest rainy season, typically lasting from May to October. Central Vietnam receives heavy precipitation from September to December. The average annual rainfall is about 1,680 mm (66 in) in the Red River Delta, 1,650 mm (65 in) along the central coast, and 1,980 mm (78 in) in the Mekong Delta. Typhoons periodically strike the central coast, and in recent years some have caused considerable loss of life and destruction of cropland.

Environmental Issues

Groundwater contamination has led to inadequate supplies of drinking water in many areas of Vietnam. Only 95 percent (2000) of the urban population has access to safe drinking water. Chemicals sprayed during the Vietnam War caused widespread defoliation in the country’s forests, contributing to soil degradation and water pollution. Coastal water pollution, along with severe overfishing, has greatly endangered the country’s marine life.

Deforestation rates in Vietnam were high in the late 20th century as a result of logging, agriculture, and heavy bombing during times of war. From 1990 to 2000, the country’s deforestation rate was -0.54 percent (1990-2000). Forests cover 30.2 percent (2000) of Vietnam, and only 3.1 percent (1997) of the land is protected in parks and other reserves. Vietnam is party to international treaties concerning climate change, endangered species, hazardous wastes, ship pollution, and wetlands.
