The City Is An Ecosystem

The City is an Ecosystem maps an interdisciplinary, community-engaged response to the great ecological crises of our time—climate change, biodiversity loss, and social inequality—which pose particular challenges for cities, where more than half the world’s population currently live. Across more than twenty chapters, the three parts of the book cover historical and scientific perspectives on the city as an ecosystem; human rights to the city in relation to urban sustainability; and the city as a sustainability classroom at all educational levels inside and outside formal classroom spaces. It argues that such efforts must be interdisciplinary and widespread to ensure an informed public and educated new generation are equipped to face an uncertain future, particularly relevant in the post-COVID-19 world. Gathering multiple interdisciplinary and community-engaged perspectives on these environmental crises, with contemporary and historical case study discussions, this timely volume cuts across the humanities and social and health sciences, and will be of interest to policymakers, urban ecologists, activists, built environment professionals, educators, and advanced students concerned with the future of our cities.

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.

This open access book presents current knowledge about ecosystem services (ES) in urban planning, and discusses various urban ES topics such as spatial distribution of urban ecosystems, population distribution, and physical infrastructure properties. The book addresses all these issues by: i) investigating to what extent ecosystem services are currently included in urban plans, and discussing what is still needed to improve planning practice; ii) illustrating how to develop ecosystem services indicators and information that can be used by urban planners to enhance plan design; iii) demonstrating the application of ES assessments to support urban planning processes through case studies; and iv) reflecting on criteria for addressing equity in urban planning through ecosystem service assessments, by exploring issues associated with the supply of, the access to and demand for ES by citizens. Through fully worked out case studies, from policy questions, to baseline analysis and indicators, and from option comparison to proposed solutions, the book offers readers detailed and accessible coverage of outstanding issues and proposed solutions to better integrate ES in city planning. The overall purpose of the book is to provide a compact reference that can be used by researchers as a key resource offering an updated perspective and overview on the field, as well as by practitioners and planners/decision makers as a source of inspiration for their activity. Additionally, the book will be a suitable resource for both undergraduate and post-graduate courses in planning and geography.

"Merging together the fields of urban ecology, environmental justice, and urban environmental education, Urban Ecosystem Justice promotes building fair, accessible, and mutually beneficial relationships between citizens and the soils, water, atmospheres, and biodiversity in their cities. This book provides a framework for re-centering issues of justice and fairness in sustainability discourse while challenging the profound ecological alienation experienced by urban residents. While the urban sustainability movement has had many successes in the past few decades, there remain areas for it to grow. For one, the benefits of sustainability have disproportionately benefited wealthier city residents, with concerns over equity, justice and social sustainability frequently taking a back seat to economic and environmental considerations. Additionally, many city dwellers remain estranged from and unfamiliar with ecological processes, with urban environments often thought of as existing outside of nature or as hopelessly degraded. Through a citizen-centered lens, the book offers a guide to reconciling these issues by demonstrating how questions of equity, access, and justice apply to the biophysical dimensions of the urban ecosystem: soil, water, air, waste, and biodiversity. Drawing heavily from the fields of urban ecology, environmental justice, and ecological design, this book lays out a science of cities for people: a pedagogical platform that can be used to promote ecological literacy in underrepresented urban communities through affordable and decentralized means. This book provides both a theoretical and practical field guide to students and researchers of urban sustainability, city planners, architects, policymakers and activists wishing to develop reciprocal relationships with urban ecologies"--

As human activity and environmental change come to be increasingly recognized as intertwined phenomena on a rapidly urbanizing planet, the field of urban ecology has risen to offer useful ways of thinking about coupled human and natural systems. On the forefront of this discipline is Marina Alberti, whose innovative work offers a conceptual framework for uncovering fundamental laws that govern the complexity and resilience of cities, which she sees as key to understanding and responding to planetary change and the evolution of Earth. Bridging the fields of urban planning and ecology, Alberti describes a science of cities that work on a planetary scale and that links unpredictable dynamics to the potential for innovation. It is a science that considers interactions - at all scales - between people and built environments and between cities and their larger environments. Cities That Think like Planets advances strategies for planning a future that may look very different from the present, as rapid urbanization could tip the Earth toward abrupt and nonlinear change. Alberti's analyses of the various hybrid ecosystems, such as self-organization, heterogeneity, modularity, multiple equilibria, feedback, and transformation, may help humans participate in guiding the Earth away from inadvertent collapse and toward a new era of planetary co-evolution and resilience.

The book aims to capture, describe and convey the current significance, the values and potentials of urban biodiversity and ecosystem services to scientists and professionals in the context of sustainable urban development and ongoing urbanization processes. Current developments, different approaches and future challenges in the competition of green spaces and urban land consumption in China and Germany are elaborated, discussed and illustrated within case studies and good practice examples. The strategic goal is a long-term appreciation of the potentials and increased consideration of urban green spaces in city planning and development. This book provides tangible recommendations for urban planners, politicians and stakeholders in the fields of green infrastructure at the interface of environment and urban landscape.

The urban environment – buildings, cities and infrastructure – represents one of the most important contributors to climate change, while at the same time holding the key to a more sustainable way of living. The transformation from traditional to sustainable systems requires interdisciplinary knowledge of the re-design, construction, operation and maintenance of the built environment. Sustainable Urban Environments: An Ecosystem Approach presents fundamental knowledge of the built environment. Approaching the topic from an ecosystems perspective, it shows the reader how to combine diverse practical elements into sustainable solutions for future buildings and cities. You’ll learn to connect problems and solutions at different spatial scales, from urban ecology to material, water and energy use, from urban transport to livability and health. The authors introduce and explore a variety of governance tools that support the transformation process, and show how they can help overcome institutional barriers. The book concludes with an account of promising perspectives for achieving a sustainable built environment in industrialized countries. Offering a unique overview and understanding of the most pressing challenges in the built environment, Sustainable Urban Environments helps the reader grasp opportunities for integration of knowledge and technologies in the design, construction and management of the built environment. Students and practitioners who are eager to look beyond their own fields of interest will appreciate this book because of its depth and breadth of coverage.
