The sharing economy and collaborative consumption are attracting a great deal of interest due to their business, legal and civic implications. The consequences of the spreading of practices of sharing in urban environments and under daily dynamics are underexplored. This Special Issue aims to address if and how sharing shapes cities, the way that spaces are designed and lived in if social interactions are escalated, and the ways that habits and routines take place in post-individualistic society. In particular, the following key questions are of primary interest: Urban fabric: How is ‘sharing’ shaping cities? Does it represent a paradigm shift with tangible and physical reverberations on urban form? How are shared mobility, work, inhabiting reconfiguring the urban and social fabric? Social practices: Are new lifestyles and practices related to sharing changing the use and design of spaces? To what extent is sharing triggering a production and consumption paradigm shift to be reflected in urban arrangements and infrastructures? Sustainability: Does sharing increase the intensity of use of space and assets, or, rather, does it increase them to meet the expectations of convenience for urban lifestyles? To what extent are these phenomena fostering more economically-, socially-, and environmentally-sustainable practices and cities? Policy: How can policy makers and municipalities interact with these bottom-up and phenomena and grassroots innovation to create more sustainable cities? Scholars responded to the above questions from the fields of urban studies, urban planning and design, sociology, geography, theoretically-grounded and informed by the results of fieldwork activities.

The topic of streets and street design is of compelling interest today as public officials, developers, and community activists seek to reshape urban patterns to achieve more sustainable forms of growth and development. Streets and the Shaping of Towns and Cities traces ideas about street design and layout back to the early industrial era in London suburbs and then on through their institutionalization in housing and transportation planning in the United States. It critiques the situation we are in and suggests some ways out that are less rigidly controlled, more flexible, and responsive to local conditions. Originally published in 1997, this edition includes a new introduction that addresses topics of current interest including revised standards from the Institute of Transportation Engineers; changes in city plans and development standards following New Urbanist, Smart Growth, and sustainability principles; traffic calming; and ecologically oriented street design.

Does planning in contested cities inadvertedly make the divisions worse? The 60s and 70s saw a strong role of planning, social engineering, etc but there has since been a move towards a more decentralised ‘community planning’ approach. The book examines urban planning and policy in the context of deeply contested space, where place identity and cultural affinities are reshaping cities. Throughout the world, contentions around identity and territory abound, and in Britain, this problem has found recent expression in debates about multiculturalism and social cohesion. These issues are most visible in the urban arena, where socially polarised communities co-habit cities also marked by divided ethnic loyalties. The relationship between the two is complicated by the typical pattern that social disadvantage is disproportionately concentrated among ethnic groups, who also experience a social and cultural estrangement, based on religious or racial identity. Navigating between social exclusion and community cohesion is essential for the urban challenges of efficient resource use, environmental enhancement, and the development of a flourishing economy. The book addresses planning in divided cities in a UK and international context, examining cities such as Chicago, hyper-segregated around race, and Jerusalem, acting as a crucible for a wider conflict. The first section deals with concepts and theories, examining the research literature and situating the issue within the urban challenges of competitiveness and inclusion. Section 2 covers collaborative planning and identifies models of planning, policy and urban governance that can operate in contested space. Section 3 presents case studies from Belfast, Chicago and Jerusalem, examining both the historical/contemporary features of these cities and their potential trajectories. The final section offers conclusions and ways forward, drawing the lessons for creating shared space in a pluralist cities and addressing cohesion and multiculturalism. • Addresses important contemporary issue of social cohesion vs. urban competitiveness • focus on impact of government policies will appeal to practitioners in urban management, local government and regeneration • Examines role of planning in cities worldwide divided by religion, race, socio-economic, etc • Explores debate about contested space in urban policy and planning • Identifies models for understanding contested spaces in cities as a way of improving effectiveness of government policy

Urban greening policies and measures have recently shown a high potential impact on the design and reshaping of the built environment, especially in urban regeneration processes. This book provides insights on analytical methods, planning strategies and shared governance tools for successfully integrating Nature-Based Solutions (NBS) in the urban planning practice. The selected contributions present real-life application cases, in which the mainstreaming of NBS are investigated according to two main challenges: the planning and designing of physical and spatial integration of NBS in cities on one side, and the implementation of suitable shared governance models and co-creation pathways on the other.

This book offers an overview of recent scientific and professional literature on urban greening and urban ecology, focusing on diverse disciplines such as landscape architecture, geography, urban ecology, urban climatology, biodiversity conservation, urban governance, architecture and urban hydrology. It includes contributions in which academics, public policy experts and practitioners share their considerable knowledge on the multi-faceted aspects of greening cities. The greening of cities has witnessed a global resurgence over the past two decades and has made a significant contribution to urban liveability and sustainability, as well as increasing resilience. As urban greening efforts continue to expand, it is useful to promote recent advances in our understanding of various aspects of planning, design and management of urban greenery, but at the same time, it is also important to realize that there are important gaps in our knowledge and that further research is needed. The book is organized in three main parts: concepts, functions and forms of urban greening. The first part examines the historical roots of greening cities and how the burgeoning field of urban ecology can contribute useful principles and strategies to guide the planning, design and management of urban greening. The second part shifts the focus to the diverse range of services – the functions – provided by urban greening, such as those related to urban climate, urban biodiversity, human health, and community building. The final part explores conventional, often neglected, but important forms of urban greenery such as urban woodlands and urban farms, as well as relatively recent forms of urban greenery like those integrated with buildings and waterways. It offers a ready reference resource for researchers, practitioners and policy-makers to grasp the critical issues and trigger further studies and applications in the quest for high-performance green cities.

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.

An argument that operational urban planning can be improved by the application of the tools of urban economics to the design of regulations and infrastructure. Urban planning is a craft learned through practice. Planners make rapid decisions that have an immediate impact on the ground—the width of streets, the minimum size of land parcels, the heights of buildings. The language they use to describe their objectives is qualitative—“sustainable,” “livable,” “resilient”—often with no link to measurable outcomes. Urban economics, on the other hand, is a quantitative science, based on theories, models, and empirical evidence largely developed in academic settings. In this book, the eminent urban planner Alain Bertaud argues that applying the theories of urban economics to the practice of urban planning would greatly improve both the productivity of cities and the welfare of urban citizens. Bertaud explains that markets provide the indispensable mechanism for cities’ development. He cites the experience of cities without markets for land or labor in pre-reform China and Russia; this “urban planners’ dream” created inefficiencies and waste. Drawing on five decades of urban planning experience in forty cities around the world, Bertaud links cities’ productivity to the size of their labor markets; argues that the design of infrastructure and markets can complement each other; examines the spatial distribution of land prices and densities; stresses the importance of mobility and affordability; and critiques the land use regulations in a number of cities that aim at redesigning existing cities instead of just trying to alleviate clear negative externalities. Bertaud concludes by describing the new role that joint teams of urban planners and economists could play to improve the way cities are managed.

Shaping Places explains how towns and cities can turn real estate development to their advantage to create the kind of places where people want to live, work, relax and invest. It contends that the production of quality places which enhance economic prosperity, social cohesion and environmental sustainability require a transformation of market outcomes. The core of the book explores why this is essential, and how it can be delivered, by linking a clear vision for the future with the necessary means to achieve it. Crucially, the book argues that public authorities should seek to shape, regulate and stimulate real estate development so that developers, landowners and funders see real benefit in creating better places. Key to this is seeing planners as market actors, whose potential to shape the built environment depends on their capacity to understand and transform the embedded attitudes and practices of other market actors. This requires planners to be skilled in understanding the political economy of real estate development and successful in changing its outcomes through smart intervention. Drawing on a strong theoretical framework, the book reveals how the future of places will come to be shaped through constant interaction between State and market power. Filled with international examples, essential case studies, color diagrams and photographs, this is essential reading for undergraduate and graduate students taking planning, property, real estate or urban design courses as well as for social science students more widely who wish to know how the shaping of place really occurs.

This book provides valuable insights into how cities are innovating in the field of the sharing economy through case studies. Each chapter explains how different cities have employed the sharing economy to solve their sui generis problems. The concept of Sharing Cities is getting considerable traction with grassroots groups and city governments around the world. Starting with the earliest Sharing City, Seoul, under the efforts of different Sharing Economy Associations and Organizations, more and more cities are being transformed. This book aims to highlight the positive changes that the sharing economy brings to cities and will be a valuable reference to those working in this emerging field.
