A distinctive feature of urbanization in the last 50 years is the expansion of urban populations and built development well beyond what was earlier conceived as the city limit, resulting in metropolitan areas. This is challenging the relevance of traditional municipal boundaries, and by extension, traditional governing structures and institutions. "Steering the Metropolis: Metropolitan Governance for Sustainable Urban Development,” encompasses the reflections of thought and practice leaders on the underlying premises for governing metropolitan space, sectoral adaptations of those premises, and dynamic applications in a wide variety of contexts. Those reflections are structured into three sections. Section 1 discusses the conceptual underpinnings of metropolitan governance, analyzing why political, technical, and administrative arrangements at this level of government are needed. Section 2 deepens the discussion by addressing specific sectoral themes of mobility, land use planning, environmental management, and economic production, as well as crosscutting topics of metropolitan governance finance, and monitoring and evaluation. Section 3 tests the concepts and their sectoral adaptations against the practice, with cases from Africa, America, Asia, and Europe.

Built on an estuary, New York City is rich in population and economic activity but poor in available land to manage the needs of a modern city. Since consolidation of the five boroughs in 1898, New York has faced innumerable challenges, from complex water and waste management issues, to housing and feeding millions of residents in a concentrated area, to dealing with climate change in the wake of Superstorm Sandy, and everything in between. Any consideration of sustainable urbanism requires understanding how cities have developed the systems that support modern life and the challenges posed by such a concentrated population. As the largest city in the United States, New York City is an excellent site to investigate these concerns. Featuring an array of the most distinguished and innovative urban environmental historians in the field, Coastal Metropolis offers new insight into how the modern city transformed its air, land, and water as it grew.
