The financial services group expects Africa's GDP growth to average 5% through to 2015, and notes that countries which offered the most FDI opportunities include SA, Kenya, Nigeria, Ghana and Angola.
Current African projects under way in water, electricity and transport infrastructure amount to $22-billion (about R170-billion).
Africa has relied on expatriates over the past 50 years and organisations spend $4-billion (about R31-billion) annually to recruit and pay 100000 expatriates to work on the continent.
Another challenge Africa faces is the low number of adults with tertiary education qualifications.
Across sub-Saharan Africa, only 0.38% of adults have a tertiary education compared with a South African average of 0.60%. Kenya leads the continent with 2%, against a global average of 3.94% of adults with tertiary education.
