Geography of Botswana
Botswana is a landlocked country located in Southern Africa, north of South Africa. Botswana occupies an area of , of which are land. Botswana has land boundaries of combined length , of which the constituent boundaries are shared with Namibia, for ; South Africa ; Zimbabwe, and Zambia, . Much of the population of Botswana is concentrated in the eastern part of the country. Sunshine totals are high all year round although winter is the sunniest period. The whole country is windy and dusty during the dry season. Geography. The land is predominantly flat to gently undulating tableland, although there is some  hilly country, where mining is carried out. The Kalahari Desert is in the central and the southwest. The Okavango Delta, one of the world's largest inland deltas, is in the northwest and the Makgadikgadi Pans, a large salt pan lies in the north-central area. The Makgadikgadi has been established as an early habitation area for primitive man; This large seasonal wetland is composed of several large component pans, the largest being Nwetwe Pan, Sua Pan and Nxai Pan. Botswana's lowest elevation point is at the junction of the Limpopo and Shashe Rivers, at a height of . The  highest point is Monalanong Hill, at . The country is divided into four drainage regions, which are sometimes indistinct due to the arid nature of the climate: Except for the Chobe, Okavango, Boteti and Limpopo rivers, most of Botswana's rivers cease to flow during the dry and early rainy seasons. Climate. Botswana is semi-arid, due to the short rain season. However, the relatively high altitude of the country and its continental situation gives it a subtropical climate. The country is remote from moisture-laden air flows for most of the year. The dry season lasts from April to October  in the south and to November in the north where, however, rainfall totals are higher. The south of the country is most exposed to cold winds during the winter period (early May to late August) when average temperatures are around . The whole country has hot summers with average temperatures around . Sunshine totals are high all year round although winter is the sunniest period. The whole country is windy and dusty during the dry season. Natural hazards. Botswana is affected by periodic droughts, and seasonal August winds blow from the west, carrying sand and dust, which can obscure visibility. Environment. Current  environmental issues in Botswana are overgrazing, desertification and the existence of only limited fresh water resources. Research from scientists has found that the common practice of overstocking cattle to cope with drought losses actually depletes scarce biomass, making ecosystems more vulnerable. The study of the district predicts that by 2050 the cycle of mild drought is likely to become shorter —18 months instead of two years—due to climate change. International agreements. Botswana is a party to the following international agreements: Biodiversity, Climate Change, Desertification, Endangered Species, Hazardous Wastes, Law of the Sea, Nuclear Test Organization, Ozone Layer Protection and  Wetlands.
