Despite a recent slowdown in gross domestic product (GDP) growth, Africa cannot afford not to press on with plans to develop its transport and energy networks, said World Bank president, Jim Yong Kim in a statement.
Governments therefore need to maintain macro-economic stability to attract capital that remains willing to commit to the continent even though investment in emerging markets is at its lowest level in around 35 years, said Kim.
GDP growth in sub-Saharan Africa in 2015 is expected to remain at 3.7%, its lowest level since 2009, according to World Bank figures.
The continent's commodities producers, such as Ghana and Zambia, have been especially hard hit by lower global prices and there is a real danger of over-production, he said.
"Right now we have to do everything we can to bring together the bankable (infrastructure) projects that even in a period of low growth will attract private investors," Kim commented.
