percentage of africa that is desert
Deserts in Africa are growing by the year and some geographers would say over half of Africa is desert and they may not be wrong. The main deserts, including the Sahara and the Kalahari, are well known and demarcated. The combined area of these 'official' deserts is 33 percent of Africa's total land mass. Other unofficial desert areas are also starting to turn into deserts. A big example of this is the Sahel which is traditionally classified as a semi-arid belt of savannah that runs east-west on the southern edge of the Sahara.
