Botswana is landlocked, bordered to the south and east by South Africa, to the northeast by Zimbabwe and to the north and west by Namibia. It also touches Zambia just west of the Victoria Falls. The tableland of the Kalahari Desert covers the centre and south. The principal wildlife areas are the Okavango Delta to the northwest, the largest inland delta in the world, which includes the Moremi Game Reserve; Chobe National Park in the north, including Savute and the Linyanti Marshes; and Kgalagadi Transfrontier National Park in the far southwest, co-managed with South Africa.
The majority of the population lives in the southeast around Gaborone, Serowe and Kanye along the South African border. The vast arid sandveld of the Kalahari occupies much of central and western Botswana. The seasonal rains bring a considerable difference to the vegetation, especially in the Makgadikgadi Pans and the Okavango Delta.
