The future of humanity is urban, and the nature of urban space enables, and necessitates, sharing -- of resources, goods and services, experiences. Yet traditional forms of sharing have been undermined in modern cities by social fragmentation and commercialization of the public realm. In Sharing Cities, Duncan McLaren and Julian Agyeman argue that the intersection of cities' highly networked physical space with new digital technologies and new mediated forms of sharing offers cities the opportunity to connect smart technology to justice, solidarity, and sustainability. McLaren and Agyeman explore the opportunities and risks for sustainability, solidarity, and justice in the changing nature of sharing. McLaren and Agyeman propose a new "sharing paradigm," which goes beyond the faddish "sharing economy" -- seen in such ventures as Uber and TaskRabbit -- to envision models of sharing that are not always commercial but also communal, encouraging trust and collaboration. Detailed case studies of San Francisco, Seoul, Copenhagen, Medellín, Amsterdam, and Bengaluru (formerly Bangalore) contextualize the authors' discussions of collaborative consumption and production; the shared public realm, both physical and virtual; the design of sharing to enhance equity and justice; and the prospects for scaling up the sharing paradigm though city governance. They show how sharing could shift values and norms, enable civic engagement and political activism, and rebuild a shared urban commons. Their case for sharing and solidarity offers a powerful alternative for urban futures to conventional "race-to-the-bottom" narratives of competition, enclosure, and division.

In cities around the world, planning and health experts are beginning to understand the role of social and environmental conditions that lead to trauma. By respecting the lived experience of those who were most impacted by harms, some cities have developed innovative solutions for urban trauma. In Cities for Life, public health expert Jason Corburn shares lessons from three of these cities: Richmond, California; Medellín, Colombia; and Nairobi, Kenya. Corburn draws from his work with citizens, activists, and decision-makers in these cities over a ten-year period, as individuals and communities worked to heal from trauma--including from gun violence, housing and food insecurity, poverty, and other harms. Cities for Life is about a new way forward with urban communities that rebuilds our social institutions, practices, and policies to be more focused on healing and health.

It's time for America to move beyond zoning, argues city planner M. Nolan Gray in Arbitrary Lines: How Zoning Broke the American City and How to Fix It. With lively explanations, Gray shows why zoning abolition is a necessary--if not sufficient--condition for building more affordable, vibrant, equitable, and sustainable cities. Gray lays the groundwork for this ambitious cause by clearing up common misconceptions about how American cities regulate growth and examining four contemporary critiques of zoning (its role in increasing housing costs, restricting growth in our most productive cities, institutionalizing racial and economic segregation, and mandating sprawl). He sets out some of the efforts currently underway to reform zoning and charts how land-use regulation might work in the post-zoning American city. Arbitrary Lines is an invitation to rethink the rules that will continue to shape American life--where we may live or work, who we may encounter, how we may travel. If the task seems daunting, the good news is that we have nowhere to go but up

How did neighborhood groceries, parish halls, factories, and even saloons contribute more to urban vitality than did the fiscal might of postwar urban renewal? With a novelist’s eye for telling detail, Douglas Rae depicts the features that contributed most to city life in the early “urbanist” decades of the twentieth century. Rae’s subject is New Haven, Connecticut, but the lessons he draws apply to many American cities. City: Urbanism and Its End begins with a richly textured portrait of New Haven in the early twentieth century, a period of centralized manufacturing, civic vitality, and mixed-use neighborhoods. As social and economic conditions changed, the city confronted its end of urbanism first during the Depression, and then very aggressively during the mayoral reign of Richard C. Lee (1954–70), when New Haven led the nation in urban renewal spending. But government spending has repeatedly failed to restore urban vitality. Rae argues that strategies for the urban future should focus on nurturing the unplanned civic engagements that make mixed-use city life so appealing and so civilized. Cities need not reach their old peaks of population, or look like thriving suburbs, to be once again splendid places for human beings to live and work.

Superstorm Sandy sent a strong message that a new generation of urban development and infrastructure is desperately needed, and it must be designed with resilience in mind. As cities continue to face climate change impacts while growing in population, they find themselves at the center of resilience and green city solutions, yet political and budgetary obstacles threaten even the best-planned initiatives. In The Guide to Greening Cities, seasoned green city leaders Sadhu Johnston, Steven Nicholas, and Julia Parzen use success stories from across North America to show how to turn a green city agenda into reality. The Guide to Greening Cities is the first book written from the perspective of municipal leaders with successful, on-the-ground experience working to advance green city goals. Through personal reflections and interviews with leading municipal staff in cities from San Antonio to Minneapolis, the authors share lessons for cities to lead by example in their operations, create programs, implement high-priority initiatives, develop partnerships, measure progress, secure funding, and engage the community. Case studies and chapters highlight strategies for overcoming common challenges such as changes of leadership and fiscal austerity. The book is augmented by a companion website, launching with the publication of the book, which offers video interviews of municipal leaders, additional case studies, and other resources. Rich in tools, insights, and tricks of the trade, The Guide to Greening Cities helps professionals, policymakers, community leaders, and students understand which approaches have worked and why and demonstrates multidisciplinary solutions for creating healthy, just, and green communities.

Warfare in the twenty-first century goes well beyond conventional armies and nation-states. In a world of diffuse conflicts taking place across sprawling cities, war has become fragmented and uneven to match its settings. Yet the analysis of failed states, civil war, and state building rarely considers the city, rather than the country, as the terrain of battle. In Cities at War, Mary Kaldor and Saskia Sassen assemble an international team of scholars to examine cities as sites of contemporary warfare and insecurity. Reflecting Kaldor’s expertise on security cultures and Sassen’s perspective on cities and their geographies, they develop new insight into how cities and their residents encounter instability and conflict, as well as the ways in which urban forms provide possibilities for countering violence. Through a series of case studies of cities including Baghdad, Bogotá, Ciudad Juarez, Kabul, and Karachi, the book reveals the unequal distribution of insecurity as well as how urban capabilities might offer resistance and hope. Through analyses of how contemporary forms of identity, inequality, and segregation interact with the built environment, Cities at War explains why and how political violence has become increasingly urbanized. It also points toward the capacity of the city to shape a different kind of urban subjectivity that can serve as a foundation for a more peaceful and equitable future.

Cities for Profit examines the phenomenon of urban real estate megaprojects in Asia—massive, privately built planned urban developments that have captured the imagination of politicians, policymakers, and citizens across the region. These controversial projects, embraced by elites, occasion massive displacement and have extensive social and economic impacts. Gavin Shatkin finds commonalities and similarities in dozens of such projects in Jakarta, Kolkata, and Chongqing. Shatkin is at the vanguard of urban studies in his focus on real estate. Just as cities are increasingly defined and remapped according to the value of the land under their residents’ feet, the lives of city dwellers are shaped and constrained by their ability to keep up with rising costs of urban life. Scholars and policy and planning professionals alike will benefit from Shatkin’s comprehensive research. Cities for Profit contains insights from more than 150 interviews, site visits to projects, and data from government and nongovernmental organization reports and data, urban plans, architectural renderings, annual reports and promotional materials of developers, and newspaper and other media accounts.
