Book excerpt: Cities, Regions and Flows presents a theoretical framework for understanding the changing relationship between places and physical movement, and thoughtfully prepared case studies from five continents on how cities relate to value chains, and how they ensure accessibility and urban liveability in an increasingly contested policy environment. Moreover, the book discusses how urban policies attempt to solve related conflicts in terms of infrastructure provision, land use, local labour markets and environmental sustainability. The two subsystems that are of major interest here - urban regions on the one hand, and logistics management and physical distribution on the other - develop in quite distinct, and often contradictory, ways. Whereas urban regions face disintegration due to the expansion of the built environment and the spatio-temporal fragmentation of life-worlds and regional systems, the logistics system itself demands integration in order to keep flows moving and to reduce costs. Physical flows, networks and chains thus have a fundamental impact on urban restructuring.
