This book reconsiders the fundamental principles of zoning and city planning over the course of the past one-hundred years, and the lessons that can be learned for the future of cities. Bringing together the contributions of leading scholars, representing diverse methodologies and academic disciplines, this book studies core questions about the functionality of cities and the goals that should be promoted via zoning and planning. It considers the increasing pace of urbanization and growth of mega cities in both developed and developing countries; changing concepts on the role of mixed-use and density zoning; new policies on inclusionary zoning as a way to facilitate urban justice and social mobility; and the effects of current macrophenomena, such as mass immigration and globalization, on the changing landscape of cities. The books twelve chapters are divided into four parts, each addressing different aspects of zoning and planning by combining theoretical analysis with a close observation of diverse case studies from North America and Europe to the Middle East and developing economies. Part I offers a critical analysis of the conventional account of zoning as a top-down form of land-use regulation starting with the 1916 NYC code. Part II studies how contemporary concepts of zoning, both substantive and procedural, impact the built environment across todays cities. Part III revisits the economic foundations of zoning and urban policy in the context of domestic markets, as compared with the regulatory and market effects of interstate agreements on cross-border real estate investments. Part IV analyzes the dominant, yet often implicit social and political motives that are driving zoning policies across different countries. This volumes focus on the ties between zoning policy and economics, politics, socioeconomic conditions, and the local-to-global scope of governance will appeal to scholars and students of political science, economics, law, planning, sustainability, geography, sociology, and architecture, as well as policy-makers and practitioners, especially those in developing countries and transitional and emerging economies.
