There are a couple of African countries with very little chance of an agriculture above self-sufficiency, but in general Africa could not only feed itself but become a major agricultural exporter. But a growing population coupled with a declining agricultural industry in some countries without any birth control is of course Bono's wet dream. Food aid and charity concerts for the next decades to come.
Just like Indias population growth feeds up all its economic growth.
