geography.

At 581,730 km² Botswana is the world's 48th-largest country (after Madagascar). It is comparable in size to Madagascar, and is slightly smaller than the U.S. state of Texas or the Canadian province of Manitoba. It lies between latitudes 17° and 27°S, and longitudes 20° and 30°E.
The country is predominantly flat, tending toward gently rolling tableland. Botswana is dominated by the Kalahari Desert, which covers up to 70% of its land surface.

The Limpopo River Basin, the major landform of all of southern Africa, lies partly in Botswana, with the basins of its tributaries, the Notwane, Bonwapitse, Mahalapswe, Lotsane, Motloutse and the Shashe, located in the eastern part of the country.
