Botswana, officially the Republic of Botswana, is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 70 per cent of its territory part of the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, Zambia to the north and Zimbabwe to the northeast. With a population of slightly over 2.4 million people and a comparable land area to France, Botswana is one of the most sparsely populated countries in the world. It is essentially the nation-state of the Tswana people, who constitute nearly 80 per cent of the population.
