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.

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.

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 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.

For the first time in history, the majority of the world's population lives in cities, the result of a rapid process of urbanization that started in the second half of the twentieth century. 'Megacities' around the world are rapidly becoming the scene for deprivation, especially in the global South, and the urban excluded face the brunt of what in many cases seems like low-intensity warfare. Featuring case studies from across the globe, including Latin America, the Middle East and Africa, Megacities examines recent worldwide trends in poverty and social exclusion, urban violence and politics, and links these to the challenges faced by policy-makers and practitioners.

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.

Sustainable Mega City Communities scrutinizes the challenges encountered when designing, planning and constructing sustainable megacities. Chapters explain the role of national and local governments for the strategic planning, development, implementation, monitoring and enforcement of standards of water, air, food and products used by the community. Other chapters cover Water Delivery Systems, Sanitation and Waste Disposal Systems, Power Systems, and Public Health Systems, new green technologies, practices, and standards predicated by the need for sustainable office building and housing. - Provides an in-depth look at critical infrastructural systems, charting problems and providing possible solutions - Addresses new green technologies, practices and standards predicated by the need for sustainable office building and housing - Explains the role of national and local governments for strategic planning, development, implementation, monitoring and enforcement
