Irrigated land: 490 sq km (1993 est.)
Natural hazards: hot, dry, dust/sand-laden sirocco wind blows primarily in March and April; periodic droughts
Environment - current issues: overgrazing, deforestation, and soil erosion aggravated by drought are contributing to desertification; very limited natural fresh water resources away from the Senegal which is the only perennial river
Environment - international agreements: party to: Biodiversity, Climate Change, Desertification, Endangered Species, Hazardous Wastes, Law of the Sea, Nuclear Test Ban, Ozone Layer Protection, Ship Pollution, Wetlands signed, but not ratified: none of the selected agreements
Geography - note: most of the population concentrated in the cities of Nouakchott and Nouadhibou and along the Senegal River in the southern part of the country
