Cities And Mega Risks

This book focuses on the emergence of COVID-19 and climate change as twin mega risks to cities of both developed and developing countries. The work analyses how the pandemic has transformed city functions, promoted remote working, and affected socializing, education and learning patterns, recreation, as well as shopping and entertainment. It discusses the lessons learned from these two Mega Risks, the evolution of urban patterns and functions in their wake, and provides visionary thinking for the improvement of cities from the experiences gained. The COVID-19 Pandemic and climate change are both posing serious threats to cities' future. Together, they demand changes in the ways cities' function and operate. The work presents a case for a better understanding of the twin mega risks, the magnitude of their impacts, the responses of cities in combating these issues, and planning strategies for preparing, mitigating and adapting to these and future risks. The book is designed to provide reliable resource materials for a wide audience such as planners, professional practitioners, scientists, students, teachers and researchers working in various fields including geography, environmental sciences, social sciences, policy and planning.

Megacity development and the inherent risks and opportunities for humans and the environment is a theme of growing urgency in the 21st century. Focusing on Latin America where urbanization is most advanced, this book studies the complexity of a ‘mega-urban system’ and explores interrelations between sectors and issues by providing an in-depths study of one particular city, Santiago de Chile. The book attempts to (i) focus on the emergence of risk in megacities by analyzing risk elements, (ii) evaluate the extent and severity of risks, (iii) develop strategies to cope with adverse risks, and (iv) to guide urban development by combining concepts with empirical evidence. Drawing on the work of an interdisciplinary and international consortium of academic and professional partners, the book is written for scholars in cross-cutting areas of urban, sustainability, hazard, governance and planning research as well as practitioners from local, regional and international organizations.

In this book, an interdisciplinary research group of faculty members, researchers, professionals, and planners contributed to an understanding of the dynamics and dimensions of emerging challenges and risks in megacities in the rapidly changing urban environments in Asia and examined emerging resilience themes from the point of view of sustainability and public policy. The world’s urban population in 2009 was approximately 3.4 billion and Asia’s urban population was about 1.72 billion. Between 2010 and 2020, 411 million people will be added to Asian cities (60 % of the growth in the world’s urban population). By 2020, of the world’s urban population of 4.2 billion, approximately 2.2 billion will be in Asia. China and India will contribute 31.3 % of the total world urban population by 2025. Developing Asia’s projected global share of CO2 emissions for energy consumption will increase from 30 % in 2006 to 43 % by 2030. City regions serve as magnets for people, enterprise, and culture, but with urbanisation , the worst form of visible poverty becomes prominent. The Asian region, with a slum population of an estimated 505.5 million people, remains host to over half of the world’s slum population . The book provides information on a comprehensive range of environmental threats faced by the inhabitants of megacities. It also offers a wide and multidisciplinary group of case studies from rapidly growing megacities (with populations of more than 5 million) from developed and developing countries of Asia.

Based on a major international study, this volume provides a synthesis of scientific knowledge on megacity urbanization on the coast, environmental impacts, risks and management choices, including a focus on adaptation, mitigation and disaster risk management. It is the primary output of a major international scientific project sponsored by the International Geosphere Biosphere Programme, the Land-Ocean Interactions at the Coastal Zone programme of IHDP/IGBP, and others. It brings together the work of over 60 contributing authors and an international review board. It presents the international policy and academic community with an unbiased and high quality assessment of the state-of-the art in areas of social-ecological systems interaction. One of its main messages is that while we know a great deal about megacities of more than ten million people and about urban processes, and about coasts and their physical and ecological processes (aquatic, physical and atmospheric), there is relatively little work that focusses primarily at points of intersection between large-scale urbanization and the coast. The book responds to this gap by providing the first global synthesis of megacity and large urban region urbanization on the coast. Its focus is on environmental and development challenges, climate change and disaster. It is interdisciplinary and brings together world recognised scientists (including many IPCC lead authors) on urban climate and atmosphere, disaster risk management, demography and coastal environments.

Contemporary cities face phenomenal risks, and they face particularly high levels of mounting social and environmental risks, including social polarization, urban conflicts, riots, terror, and climate change threats. This book suggests that climate change and its resulting uncertainties challenge the concepts, procedures, and scope of conventional approaches to planning, creating a need to rethink and revise current planning methods. Therefore, this book suggests a paradigm shift in our thinking, interrogation, and planning of our cities. Based on the contemporary conditions of risk at cities, this book conceptualizes the risk city as a construct of three interlinked concepts of risk, trust, and practice. It is a construct of risk and its new evolving conditions and knowledge of uncertainties stem from climate change and other risks and uncertainties. As a construct of practices, the risk city produces social and political institutional framework and promotes practices accordingly in order to reduce risk and risk possibilities and to increase trust. In light of the complex challenges and risks to the human habitat that have emerged in recent years, many cities have prepared various types of plans aimed at addressing the challenges posed by climate change. Nonetheless, despite the importance of these plans and the major public resources invested in their formulation, we still know little about them and have yet to begin studying them and assessing their contributions . From the innovative perspective of the risk city, this book asks critical questions about the nature, vision, practices, and potential impact of the recent climate change-oriented plans. What kinds of risks do they attempt to address, what types of practices do they institute, and what types of approaches do they apply? Do they adequately address the risks and uncertainties posed? How do they contribute to the worldwide effort to reduce greenhouse gas emissions? This book uses the methodologically innovative Risk City framework to examine the nature, vision, outcomes, practices, and impact of these crucial plans, as well as their contribution to the resilience of our cities and to global efforts toward reducing greenhouse gas emissions.
