Recent research suggests that isolation from regional and international markets has contributed significantly to poverty in many Sub-Saharan African countries. Numerous empirical studies identify poor transport infrastructure and border restrictions as significant deterrents to trade expansion. In response, the African Development Bank has proposed an integrated network of functional roads for the subcontinent. Drawing on new econometric results, the authors quantify the trade-expansion potential and costs of such a network. They use spatial network analysis techniques to identify a network of primary roads connecting all Sub-Saharan capitals and other cities with populations over 500,000. The authors estimate current overland trade flows in the network using econometrically-estimated gravity model parameters, road transport quality indicators, actual road distances, and estimates of economic scale for cities in the network. Then they simulate the effect of feasible continental upgrading by setting network transport quality at a level that is functional, but less highly developed than existing roads in countries like South Africa and Botswana. The authors assess the costs of upgrading with econometric evidence from a large World Bank database of road project costs in Africa. Using a standard approach to forecast error estimation, they derive a range of potential benefits and costs. Their baseline results indicate that continental network upgrading would expand overland trade by about USD 250 billion over 15 years, with major direct and indirect benefits for the rural poor. Financing the program would require about USD 20 billion for initial upgrading and USD 1 billion annually for maintenance. The authors conclude with a discussion of supporting institutional arrangements and the potential cost of implementing them.

Sound infrastructure is critical for growth in East Africa. During 1995-2005, improvements in infrastructure boosted growth by one percentage point per year, due largely to wider access to information and communication technologies (ICTs). Although power infrastructure sapped growth in other regions of Africa, it contributed 0.2 percentage points per year growth in East Africa. If East Africa's infrastructure could be improved to the level of the strongest performing country in Africa (Mauritius), regional growth performance would be boosted by some six percentage points, with power making the strongest contribution. East Africa's infrastructure ranks behind that of southern and western Africa across a range of indicators, though in terms of access to improved sources of water and sanitation and Internet density, it is comparable with or superior to the subcontinent's leader, southern Africa. By contrast, density of fixed-line telephones, power generation capacity, and access to electricity remain extremely low, though utility performance is improving through regional power trades. The road network is relatively good, although with some lengths of poor-quality or unpaved roads. Surface transport is challenged by border crossings, port delays, slow travel, limited railways, and trade logistics, but the region has a relatively mature and competitive trucking industry. Air transport benefits from a strong hub-and-spoke structure but has made little progress toward market liberalization. Of the seven countries in the region, four are landlocked, two have populations of fewer than 10 million people, and two have an annual gross domestic product of less than USD 10 billion. The difficult economic geography of East Africa makes a regional approach to infrastructure development necessary to achieve further improvement.

Based on extensive data collection in Uganda, this paper demonstrates that the rural access index, as defined today, should not be a government objective because the benefit of such investment is minimal, whereas achieving rural accessibility at less than 2 kilometers would require massive investments that are not sustainable. Taking into account the fact that plot size is limited on average to less than 1 hectare, a farmer's transport requirement is usually minimal and does not necessarily involve massive investments in infrastructure. This is because most farmers cannot fully load a truck or pay for this service and, even if productivity were to increase significantly, the production threshold would not be reached by most individual farmers. Therefore, in terms of public policy, maintenance of the existing rural roads rather than opening new roads should be given priority; the district feeder road allocation maintenance formula should be revised to take into account economic potential and, finally, policy makers should devote their attention to innovative marketing models from other countries where smallholder loads are consolidated through private-based consolidators.
