On Thursday,the World
Bank's chief economist for Africa, Shanty
Devarajan,said "Nigeria, the largest regional
producer, can keep
supplying at 2011 levels for another 41 years,
while Angola, the second largest producer in the
region, has about 21 years remaining at current
production levels before its known reserves are
depleted.
He also said "Given the size of these reserves, it is
likely that
the dependence on oil resources in these countries
are likely to continue in the near to medium term.
Production in newly oil-rich countries such as
Ghana and Uganda could also last for several
years."
