Geography of Burkina Faso

Burkina Faso has a total area of 274,200 km² (105,870 sq mi), of which 273,800 km² (105,710 sq mi) is land and 400 km² (150 sq mi) water. Comparatively, it is slightly larger than New Zealand and Colorado. Its borders total 3,611 kilometres (2,244 mi): Benin 386 kilometres (240 mi), Ivory Coast 545 kilometres (339 mi), Ghana 602 kilometres (374 mi), Mali 1,325 kilometres (823 mi), Niger 622 kilometres (386 mi), and Togo 131 kilometres (81 mi). It has no coastline or maritime claims.

It is made up of two major types of countryside. The larger part of the country is covered by a peneplain, which forms a gently undulating landscape with, in some areas, a few isolated hills, the last vestiges of a Precambrian massif. The southwest of the country, on the other hand, forms a sandstone massif, where the highest peak, Ténakourou, is found at an elevation of 749 metres (2,457 feet). The massif is bordered by sheer cliffs up to 150 meters (490 feet) high. The average altitude of Burkina Faso is 400 meters (1,300 feet) and the difference between the highest and lowest terrain is no greater than 600 metres (2,000 feet). Burkina Faso is therefore a relatively flat country. Its elevation extremes are a lowest point at the Mouhoun (Black Volta) River (200 metres or 656 feet) and highest point at Tena Kourou (749 metres or 2,457 feet).

Provinces of Burkina Faso

Departments of Burkina Faso

The country is divided into 13 administrative regions. These regions encompass 45 provinces and 351 departments.

The country owes its former name of Upper Volta to three rivers which cross it: the Black Volta (or Mouhoun), the White Volta (Nakambé) and the Red Volta (Nazinon). The Black Volta is one of the country's only two rivers which flow year-round, the other being the Komoé, which flows to the southwest. The basin of the Niger River also drains 27% of the country's surface.

The Niger's tributaries – the Béli, the Gorouol, the Goudébo and the Dargol – are seasonal streams and flow for only four to six months a year. They still, however, can cause large floods. The country also contains numerous lakes – the principal ones are Tingrela, Bam and Dem. The country contains large ponds, as well, such as Oursi, Béli, Yomboli and Markoye. Water shortages are often a problem, especially in the north of the country.

Köppen climate classification map of Burkina Faso

Burkina Faso has a primarily tropical climate with two very distinct seasons. In the rainy season, the country receives between 600 and 900 millimetres (23.6 and 35.4 in) of rainfall; in the dry season, the harmattan – a hot dry wind from the Sahara – blows. The rainy season lasts approximately four months, May/June to September, and is shorter in the north of the country. Three climatic zones can be defined: the Sahel, the Sudan-Sahel, and the Sudan-Guinea. The Sahel in the north typically receives less than 600 millimeters (24 inches) of rainfall per year and has high temperatures, 5–47 degrees Celsius (41–117 degrees Fahrenheit).

A relatively dry tropical savanna, the Sahel extends beyond the borders of Burkina Faso, from the Horn of Africa to the Atlantic Ocean, and borders the Sahara to its north and the fertile region of the Sudan to the South. Situated between 11°3' and 13°5' north latitude, the Sudan-Sahel region is a transitional zone with regards to rainfall and temperature. Further to the south, the Sudan-Guinea zone receives more than 900 millimeters (35 inches) of rain each year and has cooler average temperatures.

Burkina Faso's natural resources include manganese, limestone, marble, phosphates, pumice, salt and small deposits of gold. 21.93% of its land is arable, and 0.26% has permanent crops as of 2012. As of 2003, 250 km² were irrigated. Its total renewable water resources as of 2011 were 12.5 m³, with a total freshwater withdrawal of 0.72 km³/yr (46% domestic, 3% industrial, 51% agricultural; this amounts to a per-capita withdrawal of 54.99 m³/yr.

Burkina Faso's fauna and flora are protected in two national parks and several reserves: see List of national parks in Africa, Nature reserves of Burkina Faso.

Recurring droughts and floods are a significant natural hazard.[9] Current environmental issues include: recent droughts and desertification severely affecting agricultural activities, population distribution, and the economy; overgrazing; soil degradation; deforestation.

Burkina Faso is party to the following international environmental agreements: Biodiversity, Climate Change, Desertification, Endangered Species, Hazardous Wastes, Marine Life Conservation, Ozone Layer Protection, Wetlands. It has signed, but not ratified, the Law of the Sea and the Nuclear Test Ban.[10][11]
