Africa may not be the first continent that springs to mind when thinking about smog-cloaked cities. But that could change, if urban centres grow as fast as forecast without sufficient checks on pollution or traffic.

That would represent a higher rate of growth than seen in China’s urban centres over two decades of economic growth there, with all the same associated risks, according to the International Energy Agency.
