Ouagadougou (/ˌwɑːɡəˈduːɡuː/; Mossi: [ˈwaɡᵊdᵊɡᵊ]) is the capital of Burkina Faso and the administrative, communications, cultural and economic centre of the nation. It is also the country's largest city, with a population of 1,475,223 (as of 2006).The city's name is often shortened to Ouaga. The inhabitants are called ouagalais. The spelling of the name Ouagadougou is derived from the French orthography common in former French African colonies.
Burkina Faso (formerly Upper Volta) is a landlocked Sahel country that shares borders with six nations. It lies between the Sahara Desert and the Gulf of Guinea, south of the loop of the Niger River, mostly between latitudes 9° and 15°N (a small area is north of 15°), and longitudes 6°W and 3°E. The land is green in the south, with forests and fruit trees, and desert in the north.
Burkina Faso has a primarily tropical climate with two very distinct seasons. In the rainy season, the country receives between 600 and 900 mm (23.6 and 35.4 in) of rainfall; in the dry season, the harmattan – a hot dry wind from the Sahara – blows.
