One of the smallest countries in Africa, Burundi is landlocked and has an equatorial climate. Burundi is a part of the Albertine Rift, the western extension of the East African Rift. The country lies on a rolling plateau in the centre of Africa. The average elevation of the central plateau is 1,707 m (5,600 ft), with lower elevations at the borders. The highest peak, Mount Heha at 2,685 m (8,810 ft), lies to the southeast of the capital, Bujumbura.
The source of the Nile River is in Bururi province and is linked from Lake Victoria to its headwaters via the Ruvyironza River. Lake Victoria is also an important water source, which serves as a fork to the Kagera River. Another major lake is Lake Tanganyika, located in much of Burundi’s southwestern corner.
Burundi’s lands are mostly agricultural or pasture. Settlement by rural populations has led to deforestation, soil erosion and habitat loss. Deforestation of the entire country is almost completely due to overpopulation, with a mere 600 km2 (230 sq mi) remaining and an ongoing loss of about 9% per annum. There are two national parks, Kibira National Park to the northwest (a small region of rain forest, adjacent to Nyungwe Forest National Park in Rwanda), Ruvubu National Park to the northeast (along the Rurubu River, also known as Ruvubu or Ruvuvu). Both were established in 1982 to conserve wildlife populations.
