Land resources in Africa
Africa is the second largest continent in the world after Asia, and with a total land area of more than 3,025.8 million hectares (ha), its landmass is more than three times that of the United States of America. Of Africa’s 53 countries, Sudan is the largest, covering 250.39 million ha and Seychelles the smallest, covering only 45,600 ha. In terms of population density, Mauritius was in 2001 the most densely populated with 583 people/100 ha, compared to Namibia, the least densely populated at 2 people/100 ha.
The African landscape is a rich and dynamic mosaic of resources, which includes forests and woodlands, arable land, mountains, deserts, coastal lands and freshwater systems, that holds vast opportunities for development and improving human well-being if managed sustainably.
