Worldwide, cities and regions are affected by structural change and face comprehensive transformation processes, many of which are yet to reveal themselves. In this context, polycentric models for development have been internationally voiced. ôPolycentric City Regions in Transformation: The Ruhr Agglomeration in International Perspectiveö discusses such models in a comparative manner and, in particular, focuses on the dynamics that shape and challenge cities and regions nowadays. The book compiles contributions from Germany, China, Canada, Portugal, Colombia, USA, Scotland, among others, which were presented in an international conference held at Essen Zollverein in June 2015.
A new 21st century urban phenomenon is emerging: the networked polycentric mega-city region. Developed around one or more cities of global status, it is characterized by a cluster of cities and towns, physically separate but intensively networked in a complex spatial division of labour. This book describes and analyses eight such regions in North West Europe. For the first time, this work shows how businesses interrelate and communicate in geographical space - within each region, between them, and with the wider world. It goes on to demonstrate the profound consequences for spatial planning and regional development in Europe - and, by implication, other similar urban regions of the world. The Polycentric Metropolis introduces the concept of a mega-city region, analyses its characteristics, examines the issues surrounding regional identities, and discusses policy ramifications and outcomes for infrastructure, transport systems and regulation. Packed with high quality maps, case study data and written in a clear style by highly experienced authors, this will be an insightful and significant analysis suitable for professionals in urban planning and policy, environmental consultancies, business and investment communities, technical libraries, and students in urban studies, geography, economics and town/spatial planning.
Winner of the Regional Studies Association's Best Book Award 2018. In the last few decades, many global cities and towns have experienced unprecedented economic, social, and spatial structural change. Today, we find ourselves at the juncture between entering a post-urban and a post-political world, both presenting new challenges to our metropolitan regions, municipalities, and cities. Many megacities, declining regions and towns are experiencing an increase in the number of complex problems regarding internal relationships, governance, and external connections. In particular, a growing disparity exists between citizens that are socially excluded within declining physical and economic realms and those situated in thriving geographic areas. This book conveys how forces of structural change shape the urban landscape. In The Post-Urban World is divided into three main sections: Spatial Transformations and the New Geography of Cities and Regions; Urbanization, Knowledge Economies, and Social Structuration; and New Cultures in a Post-Political and Post-Resilient World. One important subject covered in this book, in addition to the spatial and economic forces that shape our regions, cities, and neighbourhoods, is the social, cultural, ecological, and psychological aspects which are also critically involved. Additionally, the urban transformation occurring throughout cities is thoroughly discussed. Written by today’s leading experts in urban studies, this book discusses subjects from different theoretical standpoints, as well as various methodological approaches and perspectives; this is alongside the challenges and new solutions for cities and regions in an interconnected world of global economies. This book is aimed at both academic researchers interested in regional development, economic geography and urban studies, as well as practitioners and policy makers in urban development.
Definitions of urban entities and urban typologies are changing constantly to reflect the growing physical extent of cities and their hinterlands. These include suburbs, sprawl, edge cities, gated communities, conurbations and networks of places and such transformations cause conflict between central and peripheral areas at a range of spatial scales. This book explores the role of cities, their influence and the transformations they have undertaken in the recent past. Ways in which cities regenerate, how plans change, how they are governed and how they react to the economic realities of the day are all explored. Concepts such as polycentricity are explored to highlight the fact that cities are part of wider regions and the study of urban geography in the future needs to be cognisant of changing relationships within and between cities. Bringing together studies from around the world at different scales, from small town to megacity, this volume captures a snapshot of some of the changes in city centres, suburbs, and the wider urban region. In doing so, it provides a deeper understanding of the evolving form and function of cities and their associated peripheral regions as well as their impact on modern twenty-first century landscapes.
Thanks to reality and the stubborn resistance of history to accommodate urban planning, often cities of about the same size wind up fairly close to each other and, although they do not merge or in other ways behave as one entity, they become co-dependent either formally or informally in terms of identity if not its services. Meijers presents here his doctoral dissertation, which was undertaken with the support of an urban research project in The Netherlands. He describes polycentric urban regions and their nearly universal quest for synergy, the division of labor of one set of cities in the Randstad, Flemish Diamond and RheinRuhr areas, moving from a "central places" theory too a network model, realizing the potential of a polycentric urban region, abandoning the idea that adding up small cities makes a metropolis, and synthesizing theoretical and case study information.
This book presents new research and theory at the regional scale showing the forms metropolitan regions might take to achieve sustainability. At the city scale the book presents case studies based on the latest research and practice from Europe, Asia and North America, showing how both planning and flagship design can propel cities into world class status, and also improve sustainability. The contributors explore the tension between polycentric and potentially sustainable development, and urban fragmentation in a physical context, but also in a wider cultural, social and economic context.
Despite traditionally being a strong research topic in urban studies, inter-city relations had become grossly neglected until recently, when it was placed back on the research agenda with the advent of studies of world/global cities. More recently the ‘external relations’ of cities have taken their place alongside ‘internal relations’ within cities to constitute the full nature of cities. This collection of essays on how and why cities are connecting to each other in a globalizing world provides evidence for a new city-centered geography that is emerging in the twenty-first century. Cities in Globalization covers four key themes beginning with the different ways of measuring a ‘world city network’, ranging from analyses of corporate structures to airline passenger flows. Second is the recent European advances in studying ‘urban systems’ which are compared to the Anglo-American city networks approach. These chapters add conceptual vigour to traditional themes and provide findings on European cities in globalization. Thirdly the political implications of these new geographies of flows are considered in a variety of contexts: the localism of city planning, specialist ‘political world cities’, and the ‘war on terror’. Finally, there are a series of chapters that critically review the state of our knowledge on contemporary relations between cities in globalization. Cities in Globalization provides an up-to-date assembly of leading American and European researchers reporting their ideas on the critical issue of how cities are faring in contemporary globalization and is highly illustrated throughout with over forty figures and tables.
This edited volume provides an essential resource for urban morphology, the study of urban forms and structures, offering a much-needed mathematical perspective. Experts on a variety of mathematical modeling techniques provide new insights into specific aspects of the field, such as street networks, sustainability, and urban growth. The chapters collected here make a clear case for the importance of tools and methods to understand, model, and simulate the formation and evolution of cities. The chapters cover a wide variety of topics in urban morphology, and are conveniently organized by their mathematical principles. The first part covers fractals and focuses on how self-similar structures sort themselves out through competition. This is followed by a section on cellular automata, and includes chapters exploring how they generate fractal forms. Networks are the focus of the third part, which includes street networks and other forms as well. Chapters that examine complexity and its relation to urban structures are in part four.The fifth part introduces a variety of other quantitative models that can be used to study urban morphology. In the book’s final section, a series of multidisciplinary commentaries offers readers new ways of looking at the relationship between mathematics and urban forms. Being the first book on this topic, Mathematics of Urban Morphology will be an invaluable resource for applied mathematicians and anyone studying urban morphology. Additionally, anyone who is interested in cities from the angle of economics, sociology, architecture, or geography will also find it useful. "This book provides a useful perspective on the state of the art with respect to urban morphology in general and mathematics as tools and frames to disentangle the ideas that pervade arguments about form and function in particular. There is much to absorb in the pages that follow and there are many pointers to ways in which these ideas can be linked to related theories of cities, urban design and urban policy analysis as well as new movements such as the role of computation in cities and the idea of the smart city. Much food for thought. Read on, digest, enjoy." From the foreword by Michael Batty
