Is Africa overly dependent on oil revenue

As South African President Jacob Zuma outlined plans for oil and gas exploration in coastal waters that he said could contain as much as 9 billion barrels of crude and vast quantities of natural gas, we ask if our continent is overly dependent on oil as a major source of revenue.

President Zuma in a speech to senior South African and Malaysian officials in the port city of Durban, Zuma said "Over the next 20 years, this could lead to the production of 300 000 barrels of oil and gas per day," Zuma said, adding that the industry needed a legislative framework that would benefit both South Africa and participating firms.

But he stressed there was "significant uncertainty" about the extent of hydrocarbon resources in South Africa's waters, some of the last unexplored stretches of the continent's energy-rich coastline.
Much of the exploration effort in South Africa is being spurred by the recent discovery of massive natural gas reserves off the coast of neighbouring Mozambique and Tanzania in east Africa.

For a continent that had Agriculture as a major export and source of revenue, there is growing emphasis on exploration of oil and gas as the benefit for the nations already exploring this sector has been immense. Given the level of corruption and high number of dictators operating in oil rich African nations, is this an advisable lane to tow?
