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.

Megacities are cities of 10 million or more inhabitants. There are more than 20 megacities in the world and they are highly diverse. They concentrate national and global economic and political power as well as scientific, political and media attention. When analysing health in megacities, it is difficult to separate the effect of size from other variables. However, cities of similar size do not necessarily suffer from the same problems, and at the same time common issues can be found among cities of very different dimensions. Nevertheless, starting with an analysis of their common characteristics, we identify nine challenges that megacities face which have particular health impact: transportation, governance, water and sanitation, safety, food security, water and sanitation, health care, emergency preparedness, and environmental issues. Each challenge is analysed in terms of its relationship with urban health. They are highly influenced by the complexity of megacities in terms of population size, geographical extension, social inequalities, and usually multiple and fragmented metropolitan governments. We conclude that given the variation among megacities and the extent of commonalities between megacities and other lower population settings, the relevance of the megacity as a category in urban health is limited. Yet the identification of these challenges, and the different ways in which they are being handled, is useful for shedding light on determinants of health and potential intersectoral interventions in a range of urban settings well beyond this group of cities.

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 the twentieth century, the urban settings of the wealthy nations were largely associated with opportunity, accumulation of wealth, and better health than their rural counterparts. In the twenty-first century, demographic changes, globalization, and climate change are having important health consequences on wealthy nations and especially on low- and middle-income countries. The increasing concentration of poverty and significant inequalities between urban neighborhoods and the physical and social environments in cities are important determinants of population health. In this important new book, experts identify the priority problems and outline solutions that can generate and sustain healthy urban environments. Foreword by Michael H.
