WORLD HEALTH ORGANIZATION Global Task Force on Cholera Control Last update: 18 January 2012 CHOLERA COUNTRY PROFILE: NIGER General Country Information: The Republic of Niger is a landlocked sub-Saharan country in Western Africa, named after the Niger River. It borders Nigeria and Benin to the south, Burkina Faso and Mali to the west, Algeria and Libya to the north and Chad to the east. Its capital and largest city is Niamey. In 1922, Niger was colonized by France and French became the official language. The 1946 French constitution provided for decentralization of power. Since 1960, Niger is fully independent. In February 2010, a coup d'état occurred in Niamey and soldiers captured President Mamadou Tandja. The country was then headed by a ruling junta. A new president has been elected in February 2011. Niger's subtropical - tropical climate is mainly hot and dry, with a large deserted area. Its economy is based on farming, livestock and some of the world's largest uranium deposits. But drought cycles, desertification, grasshopper invasion, 3.3% population growth rate and the drop in world demand for uranium have undercut an already marginal economy. Niger faces chronic nutritional emergencies and the lack of rain falls in 2011 will impact food production. Malaria causes more deaths each year in Niger among children under five years of age than any other single infection.
