Journal Articles & Books
December, 2013
Eastern Africa

More than 300 million Africans, about 30 percent of the total population, live more than one day away from the nearest port. Even when ports lie within a few hundred miles, typically sparse road networks, poor maintenance, and limited transportation infrastructure translate into high access costs. The larger map illustrates cost-of-travel accessibility to 63 major African ports, based on port type, size, and capacity in terms of the estimated total number of hours, both off and on the road network, required to travel from any location in Africa to the nearest port.
