Regional integration and international connectivity via economic corridors play an essential role in reducing the isolation of West Africa's landlocked countries such as Burkina Faso. Burkina Faso's main international corridors are the Ouagadougou-Lomé road corridor connecting it to Togo, the Ouagadougou-Tema (Ghana) road corridor, and the Ouagadougou-Niamey (Niger) road corridor, as well as the Ouagadougou-Abidjan (Cote d'Ivoire) road and rail corridors. Each of the corridors plays a unique role in regional integration, national trade, and sub-national rural and urban development, by providing connectivity to consumption centers, economic production zones, and/or economically lagging areas. The national perspective suggests that the Ouagadougou-Lomé corridor is very important for Burkina Faso's imports, serving as the artery for about 40 percent of all cargo entering the country, while the Ouagadougou-Abidjan road and rail corridors play an equally crucial role in allowing Burkina Faso's exports to reach global markets. The region's trunk road infrastructure is in fair-to-good condition on most sections, although large gaps remain on corridors such as the eastern link between Lomé and Niamey. This study develops several scenarios of corridor interventions that address the inefficiencies to quantify the expected impacts in terms of real income growth and domestic market accessibility.
