Geography of Cameroon
At 183,568 sq mi (475,440 km2), Cameroon is the world's 53rd largest country. It is comparable in size to Papua New Guinea, and somewhat larger than the U.S. state of California. Cameroon's landmass is 181,252 sq mi (469,440 km2), with 2,317 sq mi (6,000 km2) of water.
The country is located in Central and West Africa, bordering the Bight of Biafra, between Equatorial Guinea and Nigeria.
Cameroon is sometimes described as "Africa in miniature" because it exhibits all the major climates and vegetation of the continent: mountains, desert, rain forest, savanna grassland, and ocean coastland. Cameroon can be divided into five geographic zones. These are distinguished by dominant physical, climatic, and vegetative features.
Cameroon's coastal plain extends 10 to 50 miles (16 to 80 km) inland from the Gulf of Guinea (part of the Atlantic Ocean) to the edge of a plateau. In the former western state, however, the mass of Mount Cameroon reaches almost to the sea. The plain is densely forested including areas of Central African mangroves especially around Douala and in the estuary of the Cross River on the border with Nigeria.
In western Cameroon is an irregular chain of trees, white waters, and six flags that extend from Mount Cameroon almost to Lake Chad at the southern tip of the country. This region includes the Bamenda, Bamiléké, and Mambilla highlands. It also contains some of the country's most fertile soils, notably around volcanic Mt. Cameroon. This area of tropical forest has been categorised by the World Wildlife Fund as the Cameroonian Highlands forests ecoregion with Mount Cameroon considered separately because as an active volcano it has a distinct environment from the other mountains.
From the forested southern plateau the land rises northward to the grassy, rugged Adamaoua (Adamawa) highlands. Stretching across Cameroon from the western mountain area, the Adamaoua forms a barrier between the north and south. Its average elevation is 3,400 feet (1,036 m).
The northern savanna plain extends from the edge of the Adamaoua to Lake Chad. Its characteristic vegetation is scrub and grass. This is region of sparse rainfall and high median temperatures has been included as part of the East Sudanian savanna ecoregion.
The climate varies with terrain, from tropical along the coast to semiarid and hot in the north. Exceedingly hot and humid, the coastal belt includes some of the wettest places on earth. For example, Debundscha, at the base of Mt. Cameroon, has an average annual rainfall of 405 inches (10,287 mm).
The country has four patterns of drainage. In the south, the principal rivers flow southwestward or westward directly to the Gulf of Guinea — the Wouri, and lesser Dibamba, Bimbia and Mungo to the Cameroon estuary near Douala; Sanaga, Nyong, and Ntem further south along the coast; Akwayafe and Manyu (which joins Nigerian Cross), and the lesser Ndian and Meme in the north of coast. The Dja and Kadeï, however, drain southeastward into the Congo River. In northern Cameroon, the Benoué River (Benue) runs north and west, eventually into the Niger, while the Logone River flows northward into Lake Chad.
Only part of Lake Chad lies within Cameroon. The rest belongs to Chad, Nigeria, and Niger. The lake varies in size according to seasonal rainfall.
