Physical Infrastructure Development addresses the key challenges of balancing economic growth, poverty alleviation, and environmental protection in the development of major physical infrastructure, ranging from transport to energy. The contributions, reflecting the perspectives of economics, engineering, planning, political science, and urban design, examine the impact of alternative financing and pricing arrangements on the sharing of burdens and benefits, and the opportunities and risks of public-private partnerships. They also assess the emerging approaches for restoring ecosystems degraded by past infrastructure development, and the strategies for promoting farsighted infrastructure planning and protecting vulnerable people impacted by physical infrastructure expansion.
