Geography of Botswana

From Wikipedia, the free encyclopedia

Botswana is a landlocked country located in Southern Africa, north of South Africa. Botswana occupies an area of 581,730 square kilometres (224,610 mi2), of which 566,730 km2 (218,820 mi2) are land. Botswana has land boundaries of combined length 4,347.15 kilometres (2,701.19 mi), of which the constituent boundaries are shared with Namibia, for 1,544 km (959 mi); South Africa 1,969 km (1,223 mi); Zimbabwe, 834 km (518 mi) and Zambia, 0.15 km (0.093 mi). Much of the population of Botswana is concentrated in the eastern part of the country.

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.[3] Botswana's lowest elevation point is at the junction of the Limpopo and Shashe Rivers, at a height of 513 m (1,683 ft). The highest point is Monalanong Hill, at 1,495 m (4,905 ft).[1] The country is divided into four drainage regions, which are sometimes indistinct due to the arid nature of the climate:

  • the Chobe River on the border with the Caprivi Strip of Namibia together with a small adjacent swampy area is part of the Zambezi basin;
  • most of the north and central region of the country is part of the Okavango inland drainage basin;
  • the easternmost part of the country falls into the Limpopo drainage basin;
  • the southern and southwestern regions, which are the driest of all, are drained by the Molopo river along the South African border and the Nossob river through the Kalahari Gemsbok National Park, and are technically part of the basin of the Orange River. None of these rivers normally flows as far as the Orange, however. (The last recorded confluence was in the 1880s.)[4]

Except for the Chobe, Okavango, Boteti and Limpopo rivers, most of Botswana's rivers cease to flow during the dry and early rainy seasons.

In Botswana forest cover is around 27% of the total land area, equivalent to 15,254,700 hectares (ha) of forest in 2020, down from 18,803,700 hectares (ha) in 1990. In 2020, naturally regenerating forest covered 15,254,700 hectares, of the naturally regenerating forest 0% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 11% of the forest area was found within protected areas. For the year 2015, 24% of the forest area was reported to be under public ownership and 76% private ownership.[5]

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 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 14 °C (57.2 °F). The whole country has hot summers with average temperatures around 26 °C (78.8 °F). Sunshine totals are high all year round although winter is the sunniest period. The whole country is windy and dusty during the dry season.[2]

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

Rain clouds over Serowe January 2019

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.[8]

Tree cover extent and loss

Global Forest Watch publishes annual estimates of tree cover loss and 2000 tree cover extent derived from time-series analysis of Landsat satellite imagery in the Global Forest Change dataset.[9][10][11][12] In this framework, tree cover refers to vegetation taller than 5 m (including natural forests and tree plantations), and tree cover loss is defined as the complete removal of tree cover canopy for a given year, regardless of cause.[13]

For Botswana, country statistics report cumulative tree cover loss of 512 ha (5.12 km2) from 2001 to 2024 (about 2.5% of its 2000 tree cover area).[9] For tree cover density greater than 30%, country statistics report a 2000 tree cover extent of 20,328 ha (203.28 km2).[9] The charts and table below display this data. In simple terms, the annual loss number is the area where tree cover disappeared in that year, and the extent number shows what remains of the 2000 tree cover baseline after subtracting cumulative loss. Forest regrowth is not included in the dataset.[9][13]
