It is no secret that Africa faces an infrastructure crisis. The low-income economies of the region have fewer miles of paved roads and fewer modern freight and passenger-transport systems than any other region in the world. Electricity is also highly unreliable; businesses in many African countries suffer from power outages on more than half of the days they work per year. Inadequate infrastructure is cited by most African firms as the single biggest obstacle to doing business.
