Urban Ecosystems

Urban Ecology covers the latest theoretical and applied concepts in urban ecological research. This book covers the key environmental issues of urban ecosystems as well as the human-centric issues, particularly those of governance, economics, sociology and human health. The goal of Urban Ecology is to challenge readers’ thinking around urban ecology from a resource-based approach to a holistic and applied field for sustainable development. There are seven major themes of the book: emerging urban concepts and urbanization, land use/land cover change, urban social-ecological systems, urban environment, urban material balance, smart, healthy and sustainable cities and sustainable urban design. Within each section, key concepts such as monitoring the urbanization phenomena, land use cover, urban soil fluxes, urban metabolism, pollution and human health and sustainable cities are covered. Urban Ecology serves as a comprehensive and advanced book for students, researchers, practitioners and policymakers in urban ecology and urban environmental research, planning and practice. Includes global case studies from over 14 countries, providing a first-hand account of recent applications Covers the phenomena of sustainable transport, nutrient recovery and human health, among many others Examines environmental issues as well as social-ecological systems and governance

As humans have come to dominate the earth, the ideal of studying and teaching ecology in pristine ecosystems has become impossible to achieve. Our planet is now a mosaic of ecosystems ranging from the relatively undisturbed to the completely built, with the majority of people living in urban environments. This accessible introduction to the principles of urban ecology provides students with the tools they need to understand these increasingly important urban ecosystems. It builds upon the themes of habitat modification and resource use to demonstrate how multiple ecological processes interact in cities and how human activity initiates chains of unpredictable unintended ecological consequences. Broad principles are supported throughout by detailed examples from around the world and a comprehensive list of readings from the primary literature. Questions, exercises and laboratories at the end of each chapter encourage discussion, hands-on study, active learning, and engagement with the world outside the classroom window.

With over half of the global human population living in urban regions, urban ecosystems may now represent the contemporary and future human environment. Consisting of green space and the built environment, they harbour a wide range of species, yet are not well understood. This book aims to review what is currently known about urban ecosystems in a short and approachable text that will serve as a key resource for teaching and learning related to the urban environment. It covers both physical and biotic components of urban ecosystems, key ecological processes, and the management of ecological resources, including biodiversity conservation. All chapters incorporate case studies, boxes and questions for stimulating discussions in the learning environment.

Nowhere on Earth is the challenge for ecological understanding greater, and yet more urgent, than in those parts of the globe where human activity is most intense - cities. People need to understand how cities work as ecological systems so they can take control of the vital links between human actions and environmental quality, and work for an ecologically and economically sustainable future. An ecosystem approach integrates biological, physical and social factors and embraces historical and geographical dimensions, providing our best hope for coping with the complexity of cities. This book is a first of its kind effort to bring together leaders in the biological, physical and social dimensions of urban ecosystem research with leading education researchers, administrators and practitioners, to show how an understanding of urban ecosystems is vital for urban dwellers to grasp the fundamentals of ecological and environmental science, and to understand their own environment.

Urbanization drastically alters the ecosystems structure and functions, disrupts cycling of C and other elements along with water. It alters the energy balance and influences climate at local, regional and global scales. In 2008, urban population exceeded the rural population. In 2050, 70% of the world population will live in urban centers. The number of megacities (10 million inhabitants) increased from three in 1975 to 19 in 2007, and is projected to be 27 in 2025. Rapid urbanization is altering the ecosystem C budget. Yet, urban ecosystems have a large C sink capacity in soils and biota. Judicious planning and effective management can enhance C pool in urban ecosystems, and off-set some of the anthropogenic emissions. Principal components with regards to C sequestration include home lawns and turfs, urban forests, green roofs, park and recreational/sports facilities and urban agriculture.

This book gives an interdisciplinary overview on urban ecology. Basic understanding of urban nature development and its social reception are discussed for the European Metropolitan Area of Berlin. Furthermore, we investigate specific consequences for the environment, nature and the quality of life for city dwellers due to profound changes such as climate change and the demographic and economic developments associated with the phenomena of shrinking cities. Actual problems of urban ecology should be discussed not only in terms of natural dimensions such as atmosphere, biosphere, pedosphere and hydrosphere but also in terms of social and cultural dimensions such as urban planning, residence and recreation, traffic and mobility and economic values. Our research findings focus on streets, new urban landscapes, intermediate use of brown fields and the relationships between urban nature and the well-being of city dwellers. Finally, the book provides a contribution to the international discussion on urban ecology.

This groundbreaking work is an attempt at providing a conceptual framework to synthesize urban and ecological dynamics into a common framework. The greatest challenge for urban ecologists in the next few decades is to understand the role humans play in urban ecosystems. The development of an integrated urban ecological approach is crucial to advance ecological research and to help planners and managers solve complex urban environmental issues. This book is a major step forward.

Modern city dwellers are largely detached from the environmental effects of their daily lives. The sources of the water they drink, the food they eat, and the energy they consume are all but invisible, often coming from other continents, and their waste ends up in places beyond their city boundaries. Cities as Sustainable Ecosystems shows how cities and their residents can begin to reintegrate into their bioregional environment, and how cities themselves can be planned with nature’s organizing principles in mind. Taking cues from living systems for sustainability strategies, Newman and Jennings reassess urban design by exploring flows of energy, materials, and information, along with the interactions between human and non-human parts of the system. Drawing on examples from all corners of the world, the authors explore natural patterns and processes that cities can emulate in order to move toward sustainability. Some cities have adopted simple strategies such as harvesting rainwater, greening roofs, and producing renewable energy. Others have created biodiversity parks for endangered species, community gardens that support a connection to their foodshed, and pedestrian-friendly spaces that encourage walking and cycling. A powerful model for urban redevelopment, Cities as Sustainable Ecosystems describes aspects of urban ecosystems from the visioning process to achieving economic security to fostering a sense of place.
