    África oriental

    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.

    Across Africa buying and selling connects people. For a small-scale farmer, this trade takes place primarily within a limited geographic area based on access to market centers of a given size. The maps illustrate these areas using different colors to represent marketsheds—geographical areas and associated populations that are part of real or potential trade networks with a given market. From any location within a marketshed, it takes less time to travel to the corresponding market compared to any neighboring markets.

    Africa has long needed to significantly and sustainably intensify its smallholder agriculture. But achieving large-scale, sustainable increases in productivity is a complex process. Less-than-ideal growing conditions, limited suitable space for expansion, and a lack of infrastructure and support services may limit farmers’ prospects and give them few incentives to invest.
