Situated in the centre of southern Africa, Botswana lies at about 950 metres above sea level and more than 600 kilometres from the nearest coast. The country’s most striking features are its flatness and aridity. With the exception of the eastern part of Botswana – where the great majority of Batswana live and where the summer rainfall is slightly higher – three-quarters of the country constitutes the Kalahari Desert. This is what makes for its most remarkable aspect: The Okavango Delta is a wetland within a desert, receiving its waters from rain falling in central Africa, 1000 km away.
