Living In The Megacity Towards Sustainable Urban Environments

This book tackles the challenging issues raised by the growth of large megacities from diverse perspectives and approaches. The central question raised by the growth of megacities is what effect their growth will have on the ability of the global population to live in sustainable, livable, and safe societies. In Part I, important issues on the relationships between megacities and sustainability of the global environment are specified. Part II shows what can be learned from the history and diversity of megacities to solve challenging issues of the present. We present practical approaches that can solve the issues of megacities particularly focusing on human activities that seek the more harmonious relationship between life amenities and the natural environment: population density and urban built environment; production and trade; and environmental education and enlightenment. Part III aims to answer the question, what aspects of megacities should be measured and assessed? Barometers are necessary to control human activities in megacities. We consider how to measure and assess performances of megacities, reviewing some cases of indicators that authors have developed. This publication highlights the challenging issues of the relationships between megacities and sustainability of the global environment and related issues that have accrued from them, based on the following three scales: long-term time scale from the past to the present and future; a vast spatial scale that links global space with local spaces; and the scale of various aspects of human socio-economic activities in megacities.

For the first time in human history, more than half the world’s population is urban. A fundamental aspect of this transformation has been the emergence of giant cities, or megacities, that present major new challenges. This book examines how issues of megacity development, urban form, sustainability, and unsustainability are conceived, how governance processes are influenced by these ideas, and how these processes have in turn influenced outcomes on the ground, in some cases in transformative ways. Through 15 in-depth case studies by prominent researchers from around the world, this book examines the major challenges facing megacities today. The studies are organized around a shared set of concerns and questions about issues of sustainability, land development, urban governance, and urban form. Some of the main questions addressed are: What are the most pressing issues of sustainability and urban form in each megacity? How are major issues of sustainability understood and framed by policymakers? Is urban form considered a significant component of sustainability issues in public debates and public policy? Who are the key actors framing urban sustainability challenges and shaping urban change? How is unsustainability, risk, or disaster imagined, and how are those concerns reflected in policy approaches? What has been achieved so far, and what challenges remain? The publication of this book is a step toward answering these and other crucial questions.

First published in 1990. The options and probabilities for the future of cities are issues of outstanding contemporary importance, both in the developed and developing worlds. The Living City draws together both current mainstream ideas on their futures and various alternative views to enliven the debate and put forward an agenda for sustainable urban development, emphasizing ideas that question the economic imperatives of that development. Certain aspects of city life - the economy of the city, city-countryside relationships, the city as a cultural centre - are selected for study, as the book looks at the historical past and current experiences to speculate on the likely condition of cities in the future. In addition, the book investigates whether the Third World experience of city life is a separate experience or whether there are lessons to be learnt relating to all cities. The book will appeal to professionals in the surveying, planning and architectural fields, as well as students and academics in Planning, Geography, Economics, Architecture, Development Studies and Sociology and anyone interested in issues concerning the city and the environment.

The concept of ‘sustainable urban development’ has been pushed to the forefront of policymaking and politics as the world wakes up to the impacts of climate change and the destructive effects of the Anthropocene. Climate change has emerged to be one of the biggest challenges faced by our planet today, threatening both built and natural systems with long-term consequences, which may be irreversible. While there is a vast body of literature on sustainability and sustainable urban development, there is currently limited focus on how to cohesively bring together the vital issues of the planning, development, and management of sustainable cities. Moreover, it has been widely stated that current practices and lifestyles cannot continue if we are to leave a healthy living planet to not only the next generation, but also to the generations beyond. The current global school strikes for climate action (known as Fridays for Future) evidences this. The book advocates the view that the focus needs to rest on ways in which our cities and industries can become green enough to avoid urban ecocide. This book fills a gap in the literature by bringing together issues related to the planning, development, and management of cities and focusing on a triple-bottom-line approach to sustainability.

The twenty-first century is already an urban one. Cities are pivotal to sustainability concerns globalization, climate change, food security, environmental protection, and innovation.Today's urban actors, both citizens and their leaders, have a major responsibility as trustees of the future: their present actions will influence the shape and structure of cities, so that the generation to come may live healthy and contended lives.This volume takes the reader straight to the heart of how cities work, and identifies contemporary trends, mechanism and tools that can influence current strategies and choices.The authors show that urbanization is not a problem per se for sustainable development, but rather that cities, in all their diversity and complexity, offer solutions as well as challenges.The reader will be inspired by vital analyses of the next decade's windows of opportunity for sustainable urban growth.

As urbanization continues, and even accelerates, scientists estimate that by 2015 the world will have up to 60 ‘megacities’ – urban areas with more than five million inhabitants. With the irresistible economic attractions of urban centers, particularly in developing countries, making the influx of citizens unstoppable, many of humankind’s coming social, economic and political dramas will be played out in megacities. This book shows how geographers and Earth scientists are contributing to a better understanding of megacities. The contributors analyze the impact of socio-economic and political activities on environmental change and vice versa, and identify solutions to the worst problems. They propose ways of improving the management of megacities and achieving a greater degree of sustainability in their development. The goals, of wise use of human and natural resources, risk reduction (both social and environmental) and quality of life enhancement, are agreed upon. But, as this text proves, the means of achieving these ends are varied. Hence, chapters cover an array of topics, from health management in Indian megacities, to planning in New York, to transport solutions for the chronically traffic-choked Bangkok. Authors cover the impact of climate change on megacities, as well as less tangible issues such as socio-political fragmentation in the urban areas of Rio de Janeiro. This exploration of some of the most crucial issues that we face as a species sets out research that is of the utmost importance, with the potential to contribute substantially to global justice and peace – and thereby prosperity.

In view of the fact that, by 2050, 70% of the world’s population will live in cities, the subject of "sustainable urban design" is an important issue for UNESCO’s Cities of Design. Taking into account that urban design can make a significant contribution to positive changes in environmental and social matters, the book presents seven inspirational examples for copying; included are analyses and measures for the cities of Detroit, Graz, Istanbul, Mexico City, and Puebla, as well as non-location bound projects. The authors investigate the efficiency of certificates, climate installations for urban spaces, and new ecological, architectural, and sociological concepts for mega-cities. A reader for stakeholders at the interface of social and urban design.
