Cambodia is known as “the land of smiles.” But it’s also home to some of the world’s most endangered wildlife. There are more tigers here than anywhere else in Asia outside India.

There are also leopards, elephants, gibbons, rhinos, bears, crocodiles, and even rare birds like the giant hornbill and the white-winged duck. And while much of the country is still covered in dense forests, Cambodia’s forests are being lost rapidly. Today, less than 5% of Cambodia’s original forest cover remains.


Cambodia’s relief map is divided into four zones:

1. Central Plain

2. Transitional Plains

3. The Eastern Highlands

4. The Western Highlands

The relief map of Cambodia covers areas ranging from the low-lying alluvial plain in the center to the rugged mountain ranges along the borders of Thailand and Laos. The map provides general information about landforms, topography, soils, hydrology, vegetation, climate, and human settlement patterns.


The Cambodian landscape is defined by the Mekong River, which flows southward across the country’s center. In the north lies the Tonle Sap Lake, fed by the mighty river, while the tropical forests of the Cardamom Mountains rise in the east. The climate varies widely from region to region: the southern plains are hot and dry, the lowlands around the Mekong delta are humid and wet, and the mountains provide cool relief from the summer heat.

Most of Cambodia’s soils are sandier than those in Thailand and Vietnam. Soils are classified into three categories based on texture and nutrient content.

Red soil

Also known as krom, is largely composed of reddish clayey silt. These soils are well drained and fertile. They occur mainly in the central parts of the country, where rainfall averages about 2,500 millimeters per annum.

Yellow soil

Also called khléng consists mostly of yellow loess. This type of soil is deep and heavy. It occurs throughout much of the country except along the coast.

Black soil

Also called chhay krom is similar to red soil but contains less clay and more iron oxide. It is common in the highland regions of Ratanakiri province and Mondulkiri province.

Cambodia’s fertile soils make agriculture possible even though the country has one of the lowest levels of agricultural productivity in Southeast Asia.

Agricultural production is concentrated in the southern provinces of Kampot, Kandal, Koh Kong, Pursat, Preah Sihanouk, Svay Rieng, Takeo, and Mondulkiri. Rice is grown almost exclusively in the southern half of the country. Other important cash crops include cassava, sugarcane, coffee, and tea.

Livestock raising is another major source of income. Pigs and poultry are raised primarily for meat consumption, whereas cattle are used for milk and leather products. Beef exports account for most of the value added from livestock.


The Khmer people constitute about 75% of Cambodia’s population, making it the most populous state in Southeast Asia. Although there is no consensus on the exact number of Cambodian inhabitants, estimates range from 10 million to 15 million, depending on how many people live outside the country. In addition, some experts estimate that up to five million refugees remain displaced within Cambodia.

The Khmer language belongs to the Austroasiatic family of languages, which includes Burmese, Thai, and Malay, and several tribal languages are spoken in India. The Khmer language is written in Latin script.


The Khmer language is one of many languages spoken in Cambodia. It is the most widely used language there. Many Cambodians are fluent in the language, which is often considered the national language. This might sound contradictory since the country is also home to several ethnic groups speaking different languages. However, the Khmer language is the lingua franca of Cambodia, and even though some speakers of minority languages use it, they generally don’t consider themselves Khmers.

Cambodia is officially bilingual, although English is commonly taught in schools. Nevertheless, the vast majority of people still speak Khmer.

Plant and animal life

Cambodia covers about one-sixth of the Indochinese Peninsula. Its terrain includes mountains, hills, rivers, lakes, swamps, savannas, dense tropical forests, temperate forests, and arctic tundra. The climate varies considerably across the country.

Most of the land area lies within the tropics, where temperatures average around 90°F (32°C), although some regions near the coast that experience cooler weather. Rainfall is heaviest in the south, especially during the wet season from May to October.

The country lies entirely within the monsoon belt. During most of the year, heavy rains fall over the southern half of the peninsula, including the Mekong Delta, the Tonlé Sap River basin, and the provinces bordering Thailand. Monsoonal winds blow inland from November to April.

In general, the vegetation consists of broadleaf evergreens, conifers, and flowering shrubs. Tropical species predominate in the south. Evergreen forests cover most of the western highlands, and montane forests occur throughout the rest of the country. Mangrove swamps cover parts of the coastline.

Plant and animal life

Cambodia’s flora and fauna range from tropical rainforest to savannah grassland to mountain jungles. The country contains some 2,500 species of flowering plants. About 1,400 of those are endemic—found nowhere else in the world.

The country’s wildlife includes about 400

Cambodia ranks among the world’s least developed countries regarding health care, education, infrastructure, and economic opportunity.


The Cambodian capital Phnom Penh lies in the tropics, with a hot and humid climate throughout most of the year. The city receives around 2,500 hours of sunshine per year, and temperatures are generally high, averaging 25°C (77°F) during the day and 15°C (59°F) at night. Rainfall is heaviest during the summer, although it does occur throughout the year. Phnom Penh experiences some of the wettest weather in Southeast Asia.

Precipitation varies from 0.5 mm (0.02 inches) in January to almost 300 mm (12 inches) in October. This makes the average annual precipitation about 740 mm (29 inches). However, heavy downpours can occur during the rainy season, especially during July–October.

History of Cambodia

Cambodia has been inhabited since prehistoric times. Some artifacts indicate human settlements dating back at least 7,500 years ago. Archaeologists believe that the Khmer civilization began around 800 BC. This ancient culture flourished until it collapsed in 1431 AD, following the invasion of Angkor Wat by the Cham people.

The Khmers rebuilt their empire under Jayavarman VII, who ruled from 1181 to 1219. His son, Suryavarman I, continued his father’s work, expanding the kingdom into what became known as Indochina. He built temples and palaces throughout the region and established relations with China and India. In 1350, he died without an heir, and the throne passed to his brother, Thong.

After ruling for five years, he abdicated in favor of his nephew, Jayavarman VIII, who reigned for 30 years. During his reign, the capital city moved several times. By the 15th century, however, the Khmer Empire had declined due to foreign invasions.

In 1866, the French invaded Cambodia and forced King Norodom to sign a treaty granting France control over most of the country. In 1953, the French returned the area to Cambodia but retained sovereignty over Phnom Penh.
