Understanding Urban Metabolism

Understanding Urban Metabolism addresses the gap between the bio-physical sciences and urban planning and illustrates the advantages of accounting for urban metabolism issues in urban design decisions. Urban metabolism considers a city as a system, and distinguishes between energy and material flows as its components. Based on research from the BRIDGE project, this book deals with how the urban surface exchanges and transforms energy, water, carbon and pollutants in cities. This book also introduces a new method for evaluating how planning alternatives can modify the physical flows of urban metabolism components and how environmental and socioeconomic components interact. The inclusion of sustainability principles into urban planning provides an opportunity to place the new knowledge provided by bio-physical sciences at the centre of the planning process, but there is a strong need to bridge knowledge and practice, as well as for a better dissemination of research results and exchange of best practice. This book meets that need and provides the reader with the necessary tools to integrate an understanding of urban metabolism into urban planning practice.

A unified framework for analyzing urban sustainability in terms of cities' inflows and outflows of matter and energy. Urbanization and globalization have shaped the last hundred years. These two dominant trends are mutually reinforcing: globalization links countries through the networked communications of urban hubs. The urban population now generates more than eighty percent of global GDP. Cities account for enormous flows of energy and materials—inflows of goods and services and outflows of waste. Thus urban environmental management critically affects global sustainability. In this book, Paulo Ferrão and John Fernández offer a metabolic perspective on urban sustainability, viewing the city as a metabolism, in terms of its exchanges of matter and energy. Their book provides a roadmap to the strategies and tools needed for a scientifically based framework for analyzing and promoting the sustainability of urban systems. Using the concept of urban metabolism as a unifying framework, Ferrão and Fernandez describe a systems-oriented approach that establishes useful linkages among environmental, economic, social, and technical infrastructure issues. These linkages lead to an integrated information-intensive platform that enables ecologically informed urban planning. After establishing the theoretical background and describing the diversity of contributing disciplines, the authors sample sustainability approaches and tools, offer an extended study of the urban metabolism of Lisbon, and outline the challenges and opportunities in approaching urban sustainability in both developed and developing countries.

This open access book is the first to systematically introduce the principles of urban informatics and its application to every aspect of the city that involves its functioning, control, management, and future planning. It introduces new models and tools being developed to understand and implement these technologies that enable cities to function more efficiently – to become ‘smart’ and ‘sustainable’. The smart city has quickly emerged as computers have become ever smaller to the point where they can be embedded into the very fabric of the city, as well as being central to new ways in which the population can communicate and act. When cities are wired in this way, they have the potential to become sentient and responsive, generating massive streams of ‘big’ data in real time as well as providing immense opportunities for extracting new forms of urban data through crowdsourcing. This book offers a comprehensive review of the methods that form the core of urban informatics from various kinds of urban remote sensing to new approaches to machine learning and statistical modelling. It provides a detailed technical introduction to the wide array of tools information scientists need to develop the key urban analytics that are fundamental to learning about the smart city, and it outlines ways in which these tools can be used to inform design and policy so that cities can become more efficient with a greater concern for environment and equity.

The social and material production of urban nature has recently emerged as an important area in urban studies, human/environmental interactions and social studies. This has been prompted by the recognition that the material conditions that comprise urban environments are not independent from social, political, and economic processes, or from the cultural construction of what constitutes the ‘urban’ or the ‘natural’. Through both theoretical and empirical analysis, this groundbreaking collection offers an integrated and relational approach to untangling the interconnected processes involved in forming urban landscapes. The essays in this book attest that the re-entry of the ecological agenda into urban theory is vital both in terms of understanding contemporary urbanization processes, and of engaging in a meaningful environmental politics. They debate the central themes of whose nature is, or becomes, urbanized, and the uneven power relations through which this socio-metabolic transformation takes place. Including urban case studies, international research and contributions from prominent urban scholars, this volume will enable students, scholars and researchers of geographical, environmental and urban studies to better understand how interrelated, everyday economic, political and cultural processes form and transform urban environments.

Over half of the world’s population now lives in urban areas. Few who live in cities understand that cities, too, are ecosystems, as beholden to the laws and principles of ecology as are natural ecosystems. Understanding Urban Ecology: An Interdisciplinary Systems Approach introduces students at the college undergraduate level, or those in advanced-standing college credit high school courses, to cities as ecosystems. For graduate students it provides an overview and rich literature base. Urban planners, educators, and decision makers can use this book to help in designing a more sustainable or “green” future. The authors use a systems approach to explore the complexity and interactions of different components of a city’s ecology with an emphasis on the energy and materials required to maintain such concentrated centers of human activity and consumption. The book is written by seventeen specialized contributors and includes ten accompanying detailed field exercises to promote hands-on experience, observation, and quantification of urban ecosystem structure and function.The chapters describe one by one the different subsystems of the urban environment, their individual components and functions, and the interactions among them that create the social-ecological environments in which we live. The book’s emphasis on social-ecological metabolism provides students with the knowledge and methods needed to evaluate proposed policies for urban sustainability in terms of ecosystem capacity, potential positive and negative feedbacks, the laws of thermo-dynamics, and socio-cultural perception and adaptability.

This book provides a basic understanding and state-of-the-art of urban metabolism. Urban centres are increasingly challenged by population increase and the resultant environmental concerns including the urban sprawl and climate change. Different patterns of urbanization contribute to the changing climate via. differences in their urban metabolism represented by energy and matter. Urban metabolic studies in terms of energy and material inflows, outflows, and stocks can be associated with traditional evaluation techniques to help assess the magnitude and potential effects of variety of environmental challenges the world is facing today. Urban centres are critical real time observatories that indicate the impact anthropogenic activities have on global biogeochemical cycles. Urban processes have significant and lasting impacts on the global carbon budget. The technological and infrastructural advancements have fuelled an increase in urban inputs and outputs of material and energy. Therefore, more sustainable approaches need to be adopted in changing scenarios for urban planning, particularly for sustainable resource utilization and better waste management practices. The book emphasises on the sustainability in urban metabolism, sustainable urban planning, ecosystem services, and disaster resilience to provide an interdisciplinary understanding of urban metabolism. The book also identifies an urgent need to develop new methodological approaches for real time and reliable evaluation of urban metabolism.

Global populations have grown rapidly in recent decades, leading to ever increasing demands for shelter, resources, energy and utilities. Coupled with the worldwide need to achieve lower impact buildings and conservation of resources, the need to achieve sustainability in urban environments has never been more acute. This book critically reviews the fundamental issues and applied science, engineering and technology that will enable all cities to achieve a greater level of metropolitan sustainability, and assist nations in meeting the needs of their growing urban populations. Part one introduces key issues related to metropolitan sustainability, including the use of both urban metabolism and benefit cost analysis. Part two focuses on urban land use and the environmental impact of the built environment. The urban heat island effect, redevelopment of brownfield sites and urban agriculture are discussed in depth, before part three goes on to explore urban air pollution and emissions control. Urban water resources, reuse and management are explored in part four, followed by a study of urban energy supply and management in part five. Solar, wind and bioenergy, the role of waste-to-energy systems in the urban infrastructure, and smart energy for cities are investigated. Finally, part six considers sustainable urban development, transport and planning. With its distinguished editor and international team of expert contributors, Metropolitan sustainability is an essential resource for low-impact building engineers, sustainability consultants and architects, town and city planners, local/municipal authorities, and national and non-governmental bodies, and provides a thorough overview for academics of all levels in this field. Critically reviews the fundamental issues and applied science, engineering and technology that will enable all cities to achieve a greater level of metropolitan sustainability Will assist nations in meeting the needs of their growing urban populations Chapters discuss urban land use, the environmental impact of the build environment, the urban heat island effect, urban air pollution and emissions control, among other topics
