scale for considering economic strength and growth opportunities is “the megaregion,” a network of metropolitan centers and their surrounding areas that are spatially and functionally linked through environmental, economic, and infrastructure interactions.Recently a great deal of attention has been focused on the emergence of the European Union and on European spatial planning, which has boosted the region’s competitiveness. Megaregions applies these emerging concepts in an American context. It addresses critical questions for our future: What are the spatial implications of local, regional, national, and global trends within the context of sustainability, economic competitiveness, and social equity? How can we address housing, transportation, and infrastructure needs in growing megaregions? How can we develop and implement the policy changes necessary to make viable, livable megaregions? By the year 2050, megaregions will contain two-thirds of the U.S. population. Given the projected growth of the U.S. population and the accompanying geographic changes, this forward-looking book argues that U.S. planners and policymakers must examine and implement the megaregion as a new and appropriate framework.Contributors, all of whom are leaders in their academic and professional specialties, address the most critical issues confronting the U.S. over the next fifty years. At the same time, they examine ways in which the idea of megaregions might help address our concerns about equity, the economy, and the environment. Together, these essays define the theoretical, analytical, and operational underpinnings of a new structure that could respond to the anticipated upheavals in U.S. population and living patterns.
