It’s one of the Seven Natural Wonders of Africa, covers a flat area of more than 20,000km2, and in 2014, it became the 1,000th site to be inscribed onto the UNESCO World Heritage List. Botswana’s Okavango Delta is one of the most spectacular sites on Earth. The delta, which is made up of grasslands, marshes, lagoons and thousands of islands, is produced by seasonal flooding, peaking between June and August, Botswana’s dry winter months. During this period, it swells to three times its normal size, causing one of Africa’s greatest concentrations of wildlife. Botswana is home to the ‘Big Five’ game animals: the lion, leopard, buffalo, elephant and rhinoceros. Together with giraffe, hippos, cheetah, crocodiles and many other species, they make the Okavango Delta one of Africa’s most popular tourist destinations. Almost as diverse is the human population, which is made up of five ethnic groups, each of which has its own language. In the main, their livelihood comes from the delta.
