What Africa has achieved over the past decade is noteworthy: average growth rates of 5 per cent and inflation in single digits. Moreover, an increasingly stable and predictable economic and political environment has lessened the risks for business investors, thereby giving companies more confidence to exploit profitable investment opportunities in Africa. According to a report published by the McKinsey Global Institute in 2010 entitled Lions on the move: the progress and potential of African economies, the rate of return on investment in Africa today, even adjusting for the real and perceived business risks, is higher than in any other developing region. In addition, Africa has vast reserves of natural resources, including platinum, gold, diamonds, chromite, manganese, phosphates, copper, coal, cobalt, iron ore and uranium. It is also home to about 12 per cent of the world's oil reserves, and has huge swathes of arable land and forests.
