Sub-Saharan Africa is a study in diversity. Covering an area that spans the entire width of the continent beginning at the Sahara Desert and ending at the southernmost tip of South Africa, the region is home to countless cultures, languages, religions, plants, animals and natural resources. It’s no surprise that it captured the imagination of Europe’s earliest explorers — and that it continues to capture the imagination of current world powers eager to exploit it. And yet despite the region’s diversity, Sub-Saharan African countries have common challenges — transnational terrorism, rapid population growth, endemic poverty and corruption — that prevent them from capitalizing on their economic potential. The coming years will be critical for the region, especially as its political institutions mature in a rapidly globalizing world.
