Studies show that improved infrastructure could add 2% to Africa’s GDP growth rate and improve productivity by 40%. According to the World Bank, infrastructure has been responsible for more than half of Africa’s recent improved growth performance and has the potential to contribute even more in the future. Yet Africa’s infrastructure services in some countries are twice as expensive as elsewhere, reflecting both diseconomies of scale in production and high profit margins caused by lack of competition. Apart from new investment to meet the large unmet demand, there is also a need for the rehabilitation, upgrading and modernization of existing infrastructure systems in Africa.
