GORéE ISLANDWHO, a former slave-trading hub, is so close to Dakar, Senegal’s capital, that hundreds of amateurs swim out to it every year. Yet some days it disappears from sight, lost in a haze of pollution and dust. In the Nigerian city of Port Harcourt, part of its oil-producing region, black soot settles on everything.

Outdoor pollution in the continent is rarely measured.
