Geography
Cambodia is situated on the Indochinese peninsula, Cambodia is bordered by Thailand and Laos on the north and Vietnam on the east and south. The Gulf of Thailand is off the western coast. The size of Missouri, the country consists chiefly of a large alluvial plain ringed by mountains with the Mekong River to the east. The plain is centered around Lake Tonle Sap, which is a natural storage basin of the Mekong.


Climb
Cambodia's climate, like that of the rest of Southeast Asia, is dominated by monsoons, which are known as tropical wet and dry because of the distinctly marked seasonal differences.
Cambodia has a temperature range from 21 to 35 °C (69.8 to 95.0 °F) and experiences tropical monsoons. Southwest monsoons blow inland bringing moisture-laden winds from the Gulf of Thailand and Indian Ocean from May to October. The northeast monsoon ushers in the dry season, which lasts from November to April. The country experiences the heaviest precipitation from September to October with the driest period occurring from January to February.
Cambodia has two distinct seasons. The rainy season, which runs from May to October, can see temperatures drop to 22 °C (71.6 °F) and is generally accompanied with high humidity. The dry season lasts from November to April when temperatures can rise up to 40 °C (104 °F) around April. Disastrous flooding occurred in 2001 and again in 2002, with some degree of flooding almost every year.
Ecology
Cambodia has a wide variety of plants and animals. There are 212 mammal species, 536 bird species, 240 reptile species, 850 freshwater fish species (Tonle Sap Lake area), and 435 marine fish species. Much of this biodiversity is contained around the Tonle Sap Lake and the surrounding biosphere.[92] The Tonle Sap Biosphere Reserve s a unique ecological phenomenon surrounding the Tonle Sap. It encompasses the lake and nine provinces: Kampong Thom, Siem Reap, Battambang, Pursat, Kampong Chhnang, Banteay Meanchey, Pailin, Oddar Meanchey and Preah Vihear. In 1997, it was successfully nominated as a UNESCO Biosphere Reserve.[93] Other key habitats include the dry forest of Mondolkiri and Ratanakiri provinces and the Cardamom Mountainsecosystem, including Bokor National Park, Botum-Sakor National Park, and the Phnom Aural and Phnom Samkos wildlife sanctuaries.
The Worldwide Fund for Nature recognizes six distinct terrestrial ecoregions in Cambodia – the Cardamom Mountains rain forests, Central Indochina dry forest, Southeast Indochina dry evergreen forest, Southern Annamites montane rain forest, Tonle Sap freshwater swamp forest, and Tonle Sap-Mekong peat swamp forest.


Economy
In 2011 Cambodia's per capita income in PPP is $2,470 and $1,040 in nominal per capita. Cambodia's per capita income is rapidly increasing but is low compared to other countries in the region. Most rural households depend on agriculture and its related sub-sectors. Rice, fish, timber, garments and rubber are Cambodia's major exports. The International Rice Research Institute (IRRI) reintroduced more than 750 traditional rice varieties to Cambodia from its rice seed bank in the Philippines.These varieties had been collected in the 1960s.

Based on the Economist, IMF: Annual average GDP growth for the period 2001–2010 was 7.7% making it one of the world's top ten countries with the highest annual average GDP growth. Tourism was Cambodia's fastest growing industry, with arrivals increasing from 219,000 in 1997 to over 2 million in 2007. In 2004, inflation was at 1.7% and exports at $1.6 billion US$.
China is Cambodia's biggest source of foreign direct investment. China planned to spend $8 billion in 360 projects in the first seven months of 2011. It is also the largest source of foreign aid, providing about $600 million in 2007 and $260 million in 2008.
Oil and natural gas deposits found beneath Cambodia's territorial waters in 2005 yield great potential but remain mostly untapped, due in part to territorial disputes with Thailand.
Agriculture
Agriculture is the traditional mainstay of the Cambodian economy. Agriculture accounted for 90 percent of GDP in 1985 and employed approximately 80 percent of the work force. Rice is the principle commodity.
Major secondary crops include maize, cassava, sweet potatoes, groundnuts, soybeans, sesame seeds, dry beans, and rubber. The principal commercial crop is rubber. In the 1980s it was an important primary commodity, second only to rice, and one of the country's few sources of foreign exchange.


Lenguages
The Khmer language is a member of the Mon–Khmer subfamily of the Austroasiatic language group. French, once the language of government in Indochina, is still spoken by many older Cambodians. French is also the language of instruction in some schools and universities that are funded by the government of France. Cambodian French, a remnant of the country's colonial past, is a dialect found in Cambodia and is sometimes used in government, particularly in court. However, the increasing number of tourists from around the world has resulted in the shift from French to English
