The Environmental Advantages Of Cities

An analysis that offers evidence to challenge the widely held assumption that urbanization and environmental quality are necessarily at odds. Conventional wisdom about the environmental impact of cities holds that urbanization and environmental quality are necessarily at odds. Cities are seen to be sites of ecological disruption, consuming a disproportionate share of natural resources, producing high levels of pollution, and concentrating harmful emissions precisely where the population is most concentrated. Cities appear to be particularly vulnerable to natural disasters, to be inherently at risk from outbreaks of infectious diseases, and even to offer dysfunctional and unnatural settings for human life. In this book, William Meyer tests these widely held beliefs against the evidence. Borrowing some useful terminology from the public health literature, Meyer weighs instances of “urban penalty” against those of “urban advantage.” He finds that many supposed urban environmental penalties are illusory, based on commonsense preconceptions and not on solid evidence. In fact, greater degrees of “urbanness” often offer advantages rather than penalties. The characteristic compactness of cities, for example, lessens the pressure on ecological systems and enables resource consumption to be more efficient. On the whole, Meyer reports, cities offer greater safety from environmental hazards (geophysical, technological, and biological) than more dispersed settlement does. In fact, the city-defining characteristics widely supposed to result in environmental penalties do much to account for cities' environmental advantages. As of 2008 (according to U.N. statistics), more people live in cities than in rural areas. Meyer's analysis clarifies the effects of such a profound shift, covering a full range of environmental issues in urban settings.

With an ever-growing majority of the world's human population living in city spaces, the relationship between cities and nature will be one of the key environmental issues of the 21st Century. This book brings together a diverse set of authors to explore the various aspects of this relationship both theoretically and empirically. Rather than considering cities as wholly separate from nature, a running theme throughout the book is that cities, and city dwellers, should be characterized as intrinsic in the creation of specifically urban-generated ‘socio-natures’.

Urban areas are increasingly contributing to climate change while also suffering many of its impacts. Moreover, many cities, particularly in developing countries, continue to struggle to provide services, infrastructure and socio-economic opportunities. How do we achieve the global goals on climate change and also make room for allowing global urban development? Increasing levels of awareness and engagement on climate change at the local level, coupled with recent global agreements on climate and development goals, as well as the New Urban Agenda emerging from Habitat III, present an unprecedented opportunity to radically rethink how we develop and manage our cities. Urbanization and Climate Co-Benefits examines the main opportunities and challenges to the implementation of a co-benefits approach in urban areas. Drawing on the results of empirical research carried out in Brazil, China, Indonesia, South Africa, India and Japan, the book is divided into two parts. The first part uses a common framework to analyse co-benefits across the urban sectors. The second part examines the tools and legal and governance perspectives at the local and international level that can help in planning for co-benefits. This book will be of great interest to students, practitioners and scholars of urban studies, climate/development policy and environmental studies.

The CityForm consortium’s latest book, Dimensions of the Sustainable City, is the first book to report on an empirical multi-disciplinary study specifically designed to address urban sustainability. Drawing together the various dimensions of sustainability – economic, social, transport, energy and ecological – the book examines their relationships both to each other and to urban form. The book investigates the sustainability dimensions of cities through a series of projects based on a common list of elements of urban form, and which draw on the consortium’s latest research to review the sustainability issues of each dimension. The elements of urban form include density, land use, location, accessibility, transport infrastructure and characteristics of the built environment. The book also addresses issues such as adapting cities, psychological and ecological benefits of green space and sustainable lifestyles, each presenting a critical review of the relevant literature followed by an empirical analysis presenting the key results. Based on studies across five UK cities, the book draws out findings of relevance to sustainable cities worldwide. As well as an invaluable reference to researchers in sustainable planning and urban design, the book will provide a useful text for advanced undergraduate and graduate courses and for policy makers dealing with these issues. The CityForm consortium is a multi-disciplinary group of researchers from five universities funded by the UK Engineering and Physical Science Research Council from 2003-07.

Our cities are plagued by problems of congestion, waste, and pollution that deplete natural resources, damage the environment, and reduce the quality of life for their citizens. The irony is, as this fascinating new study shows, it doesn’t have to be like this. Building the Ecological City describes the problems we face and puts forward solutions to the question – how can we build cities that provide an acceptable standard of living for their inhabitants without depleting the ecosystems and bio-geochemical cycles on which they depend? The book suggests and examines the concept of urban metabolism which characterizes the city as a set of interlinked systems of physical flows linking air, land, and water. A series of chapters looks at the production and management of waste, energy use and air emissions, water supply and management, urban land use, and air quality issues. Within the broader context of climate change, the book then considers a range of practical strategies for restoring the health of urban ecosystems from the remediation of ‘brownfield’ land to improving air quality and making better use of water resources. A major contribution to better urban management and planning for both citizens and the environment, Building the Ecological City is an invaluable sourcebook for urban and national planners, architects, and environmental agencies.

The idea of sustainability has become central to international dialogues on development. This study focuses on cities and examines the implications that urbanization has for the future of the environment. The contributors explain how the development of infrastructure and industries poses serious threats to the environment through the pollution of air, water and soil. Many urban governments are actively initiating programs to mitigate harmful environmental impacts, and the discussions show that some forms of urban settlement are more benign than others. To assess whether cities can be sustainable in environmental terms, this book brings together comprehensive studies of the urban experience in nine major countries and regions: the United States, Canada, Western Europe, Eastern Europe, Japan, Southeast Asia, China and Hong Kong, Africa, and Latin America. The chapters examine the meaning of sustainable development in a specific region, the growth and structure of urban systems, the effects of possible climatic changes on urban areas, the political environment within which cities operate, and the pressures caused by intense urban use of services and natural resources. Chapters conclude with policy proposals for increasing sustainability.

What is a green city? What does it mean to say that San Francisco or Vancouver is more "green" than Houston or Beijing? When does urban growth lower environmental quality, and when does it yield environmental gains? How can cities deal with the environmental challenges posed by growth? These are the questions Matthew Kahn takes on in this smart and engaging book. Written in a lively, accessible style, Green Cities takes the reader on a tour of the extensive economic literature on the environmental consequences of urban growth. Kahn starts with an exploration of the Environmental Kuznets Curve (EKC)—the hypothesis that the relationship between environmental quality and per capita income follows a bell-shaped curve. He then analyzes several critiques of the EKC and discusses the implications of growth in urban population and surface area, as well as income. The concluding chapter addresses the role of cities in promoting climate change and asks how cities in turn are likely to be affected by this trend. As Kahn points out, although economics is known as the "dismal science," economists are often quite optimistic about the relationship between urban development and the environment. In contrast, many ecologists and environmentalists remain wary of the environmental consequences of free-market growth. Rather than try to settle this dispute, this book conveys the excitement of an ongoing debate. Green Cities does not provide easy answers complex dilemmas. It does something more important—it provides the tools readers need to analyze these issues on their own.
