Diverse driving forces, processes and actors are responsible for different trends in the development of megacities and large urban areas. Under the dynamics of global change, megacities are themselves changing: On the one hand they are prone to increasing socio-economic vulnerability due to pronounced poverty, socio-spatial and political fragmentation, sometimes with extreme forms of segregation, disparities and conflicts. On the other hand megacities offer positive potential for global transformation, e.g. minimisation of space consumption, highly effective use of resources, efficient disaster prevention and health care options – if good strategies were developed. At present in many megacities and urban areas of the developing world and the emerging economies the quality of life is eroding. Most of the megacities have grown to unprecedented size, and the pace of urbanisation has far exceeded the growth of the necessary infrastructure and services. As a result, an increasing number of urban dwellers are left without access to basic amenities like clean drinking water, fresh air and safe food. Additionally, social inequalities lead to subsequent and significant intra-urban health inequalities and unbalanced disease burdens that can trigger conflict and violence between subpopulations. The guiding idea of our book lies in a multi- and interdisciplinary approach to the complex topic of megacities and urban health that can only be adequately understood when different disciplines share their knowledge and methodological tools to work together. We hope that the book will allow readers to deepen their understanding of the complex dynamics of urban and megacity populations through the lens of public health, geographical and other research perspectives.
Megacities & Global Health brings together important research on infectious diseases, environmental and occupational hazards, disaster preparedness, crowding, urban ecology, and much more. The leading experts in global medicine, public health and urban health provide analysis, commentary and case studies of emerging and established megacities. Megacities & Global Health is especially relevant for researchers, program managers, global health professionals, and course directors, by providing fresh ideas and a substantial, up to date overview of this emerging field.
The editors are two of the most prominent researchers in this area. Both are at the Center for Urban Epidemiologic Studies. David Vlahov is particularly visible and known as the editor of the Journal of Urban Health. Sandro Galea is very prominent for his research on urban health; in particularly, research done on PTSD and children post-9/11. Thorough analysis of different populations in urban settings and specific health considerations Useful section on methods for the research audience. Applied in nature with section on prevention and interventions There are over 100 urban health centers in North America and there are no thorough, up-to-date ressources.
In a rapidly urbanizing and globalized world, cities have been the epicentres of COVID-19 (coronavirus). The virus has spread to virtually all parts of the world; first, among globally connected cities, then through community transmission and from the city to the countryside. This report shows that the intrinsic value of sustainable urbanization can and should be harnessed for the wellbeing of all. It provides evidence and policy analysis of the value of urbanization from an economic, social and environmental perspective. It also explores the role of innovation and technology, local governments, targeted investments and the effective implementation of the New Urban Agenda in fostering the value of sustainable urbanization.
The book Dhaka Megacity: Geospatial Perspectives on Urbanisation, Environment and Health presents the use of geospatial techniques to address a number of environmental issues, including land use change, climatic variability, urban sprawl, population density modelling, flooding, environmental health, water quality, energy resources, urban growth modelling, infectious diseases and the quality of life. Although the work is focused on the Megacity of Dhaka in Bangladesh, the techniques and methods that are used to research these issues can be utilized in any other areas where rapid population growth coupled with unplanned urbanization is leading to environmental degradation. The book is useful for people working in the area of Geospatial Science, Urban Geography, Environmental Management and International Development. Since the chapters in the book cover a range of environmental issues, this book describes useful tools for assisting informed decision making, particularly in developing countries.
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.
This next volume in the series will provide up to date Information and discussion on future approach to control several challenging Infectious Disease worldwide. The past decade has been highlighted by numerous advances in research of medical scientific knowledge. medical technology and the biological and diagnostic techniques-but somewhat less dramatic changes or improvement in management of medical conditions. This volume will address some of the emerging issues, challenges, and controversies in Infectious Diseases.
This forward-looking resource recasts the concept of healthy cities as not only a safe, pleasant, and green built environment, but also one that creates and sustains health by addressing social, economic, and political conditions. It describes collaborations between city planning and public health creating a contemporary concept of urban governance—a democratically-informed process that embraces values like equity. Models, critiques, and global examples illustrate institutional change, community input, targeted assessment, and other means of addressing longstanding sources of urban health challenges. In these ambitious pages, healthy cities are rooted firmly in the worldwide movement toward balanced and sustainable urbanization, developed not to disguise or displace entrenched health and social problems, but to encourage and foster solutions. Included in the coverage: Towards healthy urban governance in the century of the city“/li> Healthy cities emerge: Toronto, Ottawa, Copenhagen The role of policy coalitions in understanding community participation in healthy cities projects Health impact assessment at the local level The logic of method for evaluating healthy cities Plus: extended reports on healthy cities and communities in North and Latin America, Africa, Europe, Asia, Oceania, and the Middle East Healthy Cities will interest and inspire community leaders, activists, politicians, and entrepreneurs working to improve health and well-being at the local level, as well as public health and urban development scholars and professionals.
This book crosses disciplinary boundaries to investigate how the benefits of green spaces can be further incorporated in public health. In this regard, the book highlights how ecosystem services provided by green spaces affect multiple aspects of human health and well-being, offering a strategic way to conceptualize the topic. For centuries, scholars have observed the range of health benefits associated with exposure to nature. As people continue to move to urban areas, it is essential to include green spaces in cities to ensure sustained human health and well-being. Such insights can not only advance the science but also spark interdisciplinary research and help researchers creatively translate their findings into benefits for the public. The book explores this topic in the context of ‘big picture’ frameworks that enhance communication between the environmental, public health, and social sciences.
The Jevons Paradox, which was first expressed in 1865 by William Stanley Jevons in relation to use of coal, states that an increase in efficiency in using a resource leads to increased use of that resource rather than to a reduction. This has subsequently been proved to apply not just to fossil fuels, but other resource use scenarios. For example, doubling the efficiency of food production per hectare over the last 50 years (due to the Green Revolution) did not solve the problem of hunger. The increase in efficiency increased production and worsened hunger because of the resulting increase in population. The implications of this in todays world are substantial. Many scientists and policymakers argue that future technological innovations will reduce consumption of resources; the Jevons Paradox explains why this may be a false hope. This is the first book to provide a historical overview of the Jevons Paradox, provide evidence for its existence and apply it to complex systems. Written and edited by world experts in the fields of economics, ecological economics, technology and the environment, it explains the myth of efficiency and explores its implications for resource usage (particularly oil). It is a must-read for policymakers, natural resource managers, academics and students concerned with the effects of efficiency on resource use.
