Transport Corridors for Wider Socio–Economic Development

Abstract

There can be two broad objectives of transport corridor development: to improve efficiency in the transport and logistics processes in the corridor, and to generate economic development in the corridor region, capitalizing on improved connectivity and transport networks. This paper focuses on the second objective of corridor development. A transport corridor can become a tool for spatially balanced and more sustainable economic development and human well-being in the corridor region. Considering the promise of this approach, this paper undertakes a critical review of transport infrastructure development studies undertaken in Sub-Saharan and South Asian countries to find evidence of infrastructure development impacts. Evidence gathered from the review suggests that transport infrastructure development can have significant positive impacts on economic growth, income, poverty, employment, equity, and inclusion. However, there can be important trade-offs between economy and welfare and environmental quality, and the distribution of impacts can be uneven. The paper also considers how some of the transport corridor development issues are addressed and complementary interventions that may be required, and, finally, discusses lessons learned from the review and their policy implications which can be useful for future corridor designs, and provides suggestions of research studies to fill the current knowledge gaps.
