A canoe filled with food floats past a makeshift photo studio in the waterside slum of Makoko in Lagos January 22, 2013. Nigeria is often used by promoters of an "Africa Rising" narrative urging investors to buy into the continent's potential to reap a "demographic dividend" from an expanding population of young people of working age.
