Urban Air Mobility: Intelligent, Safe and Sustainable Systems for Future Transportation
by Vishnu Kumar Kaliappan Mohana Sundaram Kuppusamy Dugki MinThis book is a resource for engineers and researchers to develop intelligent, safe, and sustainable systems for urban air mobility. In recent years, the growth of the world’s urban population has increased tremendously, and it is predicted that by 2040, 70% of the world population will be living in an urban setting. Existing ground transportation will be unable to cope with such an expansion, especially as congestion and over-crowding becomes more common. An answer may be found with the advent of recent technologies such as urban air mobility, which may play a vital role in providing solutions for public transportation.The impact of modelling, analysis and application of intelligent algorithms is very much at the core of the design and implementation of Urban Air Mobility. The various chapters are configured to address the challenges in modelling, analysis, navigation, traffic control, battery efficiency, safety and security in terms of Artificial intelligence techniques.
Urban Air Quality in Europe
by Mar VianaThis book provides an overview of air quality in urban environments in Europe, focusing on air pollutant emission sources and formation mechanisms, measurement and modeling strategies, and future perspectives. The emission sources described are biomass burning, vehicular traffic, industry and agriculture, but also African dust and long-range transport of pollutants across the European regions. The impact of these emission sources and processes on atmospheric particulate matter, ozone, nitrogen oxides and volatile and semi-volatile organic compounds is discussed and critical areas for particulate matter and nitrogen dioxide in Europe are identified. Finally, this volume presents future perspectives, mainly regarding upcoming air quality monitoring strategies, metrics of interest, such as submicron and nanoparticles, and indoor and outdoor exposure scenarios.

Urban and Metropolitan Rivers: Geomorphology, Planning and Perception (The Urban Book Series)
by Joaquim Farguell Pérez Albert Santasusagna RiuThis book provides a detailed description of fluvial processes and their influence on urban sites. During the urban expansion of modern cities throughout the twentieth century, rivers have become a source of problems during high flood events. However, due to growing social pressure, especially in dense cities, rivers are viewed as new leisure areas given that they also provide highly valuable ecosystem services. People seek open and environmentally friendly spaces amidst the dense street networks of cities. Yet, we should not forget that rivers are not merely domesticated elements of nature for leisure purposes only. Flooding risks and damages are possible within urban environments. How should we address the social and ecological interactions? How should we plan for these complexities to meet the growing social requirements and needs while respecting river dynamics? Hydrologists, geomorphologists, engineers, geographers and urban planners could leverage the knowledge and examples provided to enhance the interaction between nature and society in the growing cities of the twenty-first century.

Urban and Regional Cooperation and Development: Challenges and Strategies for the Planning and Development of the Guangdong–Macao Intensive Cooperation Zone in Hengqin Island (SpringerBriefs in Geography)
by Long Zhou Bin Li Sihong Li Ngan Leng Lei Kengfong CheongThis is an open access book. This book, first of all, introduces the new unveiled Guangdong-Macao Intensive Cooperation Zone with details as a special mode of the regional collaborative development that is committed to be mutually beneficial to both sides with different political and economic systems. China's central authorities have recently issued a masterplan for constructing the Guangdong-Macao Intensive Cooperation Zone at Hengqin Island in September 2021. As China's first and last European colony and one of China’s two special administrative regions (SARs), Macao has developed the gambling industry seven times larger than that of Las Vegas. However, the problem of the homogeneous industrial structure and the urgent need to promote sustainable economic growth by regional cooperation have been important theoretical and practical issues discussed by scholars and policy-makers. The Guangdong-Macao Intensive Cooperation Zone (ICZ) is managed under special customs supervision between two boarder lines and expected to diversify Macao’s economy. Then, this book dissects the theory of regional synergistic development and its applications in a number of international comparative and cross-interdisciplinary case studies worldwide. Finally, from the perspective of land use, transportation connection, and social service, this book thoroughly explores the challenges and strategies to implement the new cooperation model within the framework of one country, two systems, two customs, and two currencies to achieve a win–win situation using updated first-hand data collected by literature review, case study, field survey, spatial analysis, and interview.

Urban and Regional Technology Planning: Planning Practice in the Global Knowledge Economy (Networked Cities Series)
by Kenneth E. Corey Mark WilsonPart of the popular Networked Cities series, Urban and Regional Technology Planning focuses on the practice of relational planning and the stimulation of local city-regional scale development planning in the context of the global knowledge economy and network society. Designed to offer scholars, practitioners, and decision makers studies on the ways of cities, technologies, and multiple forms of urban movement intersect and create the contemporary urban environment, Kenneth Corey and Mark Wilson explore the dynamics of technology-induced change that is taking place within the context of the global knowledge economy and network society. Examining first the knowledge economy itself, Wilson and Corey go on to discuss its implications before proposing ways to strategize for future intelligent development, with particular emphasis on the ALERT model for regional and local planning. An important read for those practicing or studying planning in this network society.
The Urban and Regional Transformation of Britain (Routledge Library Editions: Urban Planning #12)
by J. B. Goddard and A. G. ChampionOriginally published in 1983 The Urban and Regional Transformation of Britain, analyses economic and social changes recorded across the cities and regions of Britain since the Barlow Report. The collection analyses the whole country at a more detailed scale than the ten Standard Regions, for which most official statistics are produced. Although there are important differences between the major regions of Britain, many of the recent processes of change appear to have operated at a local level within rather than between regions. The essays in this volume bring together change at the regional and local labour market scales and provides a comprehensive statement of urban and regional change, seeking to highlight the new spatial priorities of the 1980s.

Urban Animals: Crowding in zoocities (Routledge Human-Animal Studies Series)
by Tora HolmbergThe city includes opportunities as well as constraints for humans and other animals alike. Urban animals are often subjected to complaints; they transgress geographical, legal as and cultural ordering systems, while roaming the city in what is often perceived as uncontrolled ways. But they are also objects of care, conservation practices and bio-political interventions. What then, are the "more-than-human" experiences of living in a city? What does it mean to consider spatial formations and urban politics from the perspective of human/animal relations?This book draws on a number of case studies to explore urban controversies around human/animal relations, in particular companion animals: free ranging dogs, homeless and feral cats, urban animal hoarding and "crazy cat ladies". The book explores ‘zoocities’, the theoretical framework in which animal studies meet urban studies, resulting in a reframing of urban relations and space. Through the expansion of urban theories beyond the human, and the resuscitation of sociological theories through animal studies literature, the book seeks to uncover the phenomenon of ‘humanimal crowding’, both as threats to be policed, and as potentially subversive. In this book, a number of urban controversies and crowding technologies are analysed, finally pointing at alternative modes of trans-species urban politics through the promises of humanimal crowding - of proximity and collective agency. The exclusion of animals may be an urban ideology, aiming at social order, but close attention to the level of practice reveals a much more diverse, disordered, and perhaps disturbing experience.
The Urban Archetypes of Jane Jacobs and Ebenezer Howard: Contradiction and Meaning in City Form (G - Reference, Information And Interdisciplinary Subjects Ser.)
by Abraham AkkermanEbenezer Howard, an Englishman, and Jane Jacobs, a naturalized Canadian, personify the twentieth century’s opposing outlooks on cities. Howard had envisaged small towns, newly built from scratch, fashioned on single family homes with small gardens. Jacobs embraced existing inner-city neighbourhoods emphasizing the verve of the living street. From Howard’s idea, the American Dream of garden suburbs had emerged, yet his conceptualization of a modern city received criticism for being uniform and alienated from the rest of the city. Similarly, at the turn of the new century, Jacobs’ inner-city neighbourhoods came to be recognized as the result of commodification, vacillating between poverty and newly discovered hubs of urban authenticity. Presenting Howard and Jacobs within a psychocultural context, The Urban Archetypes of Jane Jacobs and Ebenezer Howard addresses our urban crisis in the recognition that "city form" is a gendered, allegorical medium expressing femininity and masculinity within two founding features of the built environment: void and volume. Both founding contrasts bring tensions, but also the opportunities of fusion between pairs of urban polarities: human scale against superscale, gait against speed, and spontaneity against surveillance. Jacobs and Howard, in their respective attitudes, have come to embrace the two ancient archetypes, the Garden and the Citadel, leaving it to future generations to blend their two contrarian stances.
Urban Art and the City: Creating, Destroying, and Reclaiming the Sublime (Routledge Studies in Urbanism and the City)
by Argyro LoukakiThis book offers original interdisciplinary insights into cities as a diachronic creation of urban art. It engages in a sequence of historical perspectives to examine urban space as an object of apparent quasi-cycles and processes of constitution, exaltation, imitation, contestation and redemption through art. Urban art transforms the city into a human-made sublime which is explored in the context of the Eastern Mediterranean. The book probes this process primarily through the example of Athens and Byzantine Constantinople, but also Jerusalem, Cyprus and regional cities, revealing how urban space unavoidably encompasses a spatial and temporal palimpsest which is constantly emerging. It presents new ideas for both the theorization and sensuous conception of artistic reality, architecture, and planning attributes. These extend from archaic, classical and Byzantine urban splendour to current urban decline as constitution and attack on the sublime and back. Urban processes of contestation and redemption respond recently to the new ‘imperialism of debt’ and the positivist, technocratic understandings and demands of Euro-governments and neoliberal institutions, while still evoking older forms of spatial power.Offering fresh notions on art, architecture, space, antiquity, (post)-modernity and politics of the region, this book will appeal to scholars and students of geography, urban studies, art, restoration, and film theory, architecture, landscape design, planning, anthropology, sociology and history.
Urban Assemblages: How Actor-Network Theory Changes Urban Studies (Questioning Cities)
by Thomas Bender Ignacio FaríasThis book takes it as a given that the city is made of multiple partially localized assemblages built of heterogeneous networks, spaces, and practices. The past century of urban studies has focused on various aspects—space, culture, politics, economy—but these too often address each domain and the city itself as a bounded and cohesive entity. The multiple and overlapping enactments that constitute urban life require a commensurate method of analysis that encompasses the human and non-human aspects of cities—from nature to socio-technical networks, to hybrid collectivities, physical artefacts and historical legacies, and the virtual or imagined city. This book proposes—and its various chapters offer demonstrations—importing into urban studies a body of theories, concepts, and perspectives developed in the field of science and technology studies (STS) and, more specifically, Actor-Network Theory (ANT). The essays examine artefacts, technical systems, architectures, place and eventful spaces, the persistence of history, imaginary and virtual elements of city life, and the politics and ethical challenges of a mode of analysis that incorporates multiple actors as hybrid chains of causation. The chapters are attentive to the multiple scales of both the object of analysis and the analysis itself. The aim is more ambitious than the mere transfer of a fashionable template. The authors embrace ANT critically, as much as a metaphor as a method of analysis, deploying it to think with, to ask new questions, to find the language to achieve more compelling descriptions of city life and of urban transformations. By greatly extending the chain or network of causation, proliferating heterogeneous agents, non-human as well as human, without limit as to their enrolment in urban assemblages, Actor-Network Theory offers a way of addressing the particular complexity and openness characteristic of cities. By enabling an escape from the reification of the city so common in social theory, ANT’s notion of hybrid assemblages offers richer framing of the reality of the city—of urban experience—that is responsive to contingency and complexity. Therefore Urban Assemblages is a pertinent book for students, practitioners and scholars as it aims to shift the parameters of urban studies and contribute a meaningful argument for the urban arena which will dominate the coming decades in government policies.
Urban Avant-Gardes: Art, Architecture and Change
by Malcolm MilesUrban Avant-Gardes presents original research on a range of recent contemporary practices in and between art and architecture giving perspectives from a wide range of disciplines in the arts, humanities and social sciences that are seldom juxtaposed, it questions many assumptions and accepted positions. This book looks back to past avant-gardes from the nineteenth and twentieth centuries examining the theoretical and critical terrain around avant-garde cultural interventions, and profiles a range of contemporary cases of radical cultural practices. The author brings together material from a wide range of disciplines to argue for cultural intervention as a means to radical change, while recognizing that most such efforts in the past have not delivered the dreams of their perpetrators. Distinctive in that it places works of the imagination in the political and cultural context of environmentalism, this book asks how cultural work might contribute to radical social change. It is equally concerned with theory and practice - part one providing a theoretical framework and part two illustrating such frameworks with examples.
Urban Awakenings: Disturbance and Enchantment in the Industrial City
by Samuel Alexander Brendan GleesonThis book presents a series of urban investigations undertaken in the metropolis of Melbourne. It is based on the idea that ‘enchantment’ as an affective state is important to ethical and political engagement. Alexander and Gleeson argue that a sense of enchantment can give people the impulse to care and engage in an increasingly troubled world, whereas disenchantment can lead to resignation. Applying and extending this theory to the urban landscape, the authors walk their home city with eyes open to the possibility of seeing and experiencing the industrial city in different ways. This unique methodology, described as ‘urban tramping’, positions the authors as freethinking freewalkers of the city, encumbered only with the duty to look through the delusions of industrial capitalism towards its troubled, contradictory soul. These urban investigations were disrupted midway by COVID-19, a plague that ended up confirming the book’s central thesis of a fractured modernity vulnerable to various internal contradictions.
Urban Bats: Biology, Ecology, and Human Dimensions (Fascinating Life Sciences)
by Lauren Moretto Joanna L. Coleman Christina M. Davy M. Brock Fenton Carmi Korine Krista J. PatriquinThe Anthropocene is the “age of human influence”, an epoch well known for its urban impact. More than half of all people already live in cities, and this proportion is expected to rise to almost 70 percent by 2050. Like other species in urban areas, bats must contend with the pressures of profound and irreversible land cover change and overcome certain unique challenges, such as the high density of roads, lights, glass, and free-ranging domestic animals. Research on urban bats in recent decades indicates that when it comes to urban life, some bats are synanthropes. In other words, although most species of bats are negatively impacted by urbanisation, many appear to not only succeed, but also thrive in cities and towns. This observation has inspired interesting questions about bats in relation to urbanisation. Which traits and behaviours equip bats for urban success? What features of urban areas increase the likelihood that bats will successfully persist there or even colonize new areas? And how does the success of urban bats affect co-habiting humans?Our book explores the interactions between bats and urban environments through case studies and reviews. Understanding how different species interact with urban environments can reveal potential opportunities to mitigate urban threats to bats and threats posed by bats to other urban organisms, including humans. With this book, we thus aspire to provide a knowledge base to help guide current and future efforts to conserve bats.
Urban Biodiversity: From Research to Practice (Routledge Studies in Urban Ecology)
by Alessandro Ossola Jari NiemeläUrban biodiversity is an increasingly popular topic among researchers. Worldwide, thousands of research projects are unravelling how urbanisation impacts the biodiversity of cities and towns, as well as its benefits for people and the environment through ecosystem services. Exciting scientific discoveries are made on a daily basis. However, researchers often lack time and opportunity to communicate these findings to the community and those in charge of managing, planning and designing for urban biodiversity. On the other hand, urban practitioners frequently ask researchers for more comprehensible information and actionable tools to guide their actions. This book is designed to fill this cultural and communicative gap by discussing a selection of topics related to urban biodiversity, as well as its benefits for people and the urban environment. It provides an interdisciplinary overview of scientifically grounded knowledge vital for current and future practitioners in charge of urban biodiversity management, its conservation and integration into urban planning. Topics covered include pests and invasive species, rewilding habitats, the contribution of a diverse urban agriculture to food production, implications for human well-being, and how to engage the public with urban conservation strategies. For the first time, world-leading researchers from five continents convene to offer a global interdisciplinary perspective on urban biodiversity narrated with a simple but rigorous language. This book synthesizes research at a level suitable for both students and professionals working in nature conservation and urban planning and management.
Urban Biodiversity and Built Environment: Case Study of Shanghai
by Jing GanThis book proposes the concept of urban multiple habitats and then analyzes its corresponding classification, function and potential supply capability. It provides an analysis framework for studying the relationship between urban biodiversity and built environment, and for considering the loss of urban habitats caused by high-density development. It argues that urban biodiversity is a key indicator for assessing urban ecosystem services. On this basis, the book then presents a case study mainly focusing on wild birds in Shanghai, as urban wild birds and their species could be viewed as an essential indicator for evaluating healthy ecosystem of contemporary cities. Based on the empirical findings, the book proposes an assessment model for urban biodiversity performance and a range of principles, strategies and key indicators regarding the optimization of urban planning and design practice to enhance urban biodiversity performance.
Urban Blue Spaces: Planning and Design for Water, Health and Well-Being
by Simon Bell Lora E. Fleming Friedrich Kuhlmann Mathew P. White Mark J. Nieuwenhuijsen James GrellierThis book presents an evidence-based approach to landscape planning and design for urban blue spaces that maximises the benefits to human health and well-being while minimising the risks. Based on applied research and evidence from primary and secondary data sources stemming from the EU-funded BlueHealth project, the book presents nature-based solutions to promote sustainable and resilient cities. Numerous cities around the world are located alongside bodies of water in the form of coastlines, lakes, rivers and canals, but the relationship between city inhabitants and these water sources has often been ambivalent. In many cities, water has been polluted, engineered or ignored completely. But, due to an increasing awareness of the strong connections between city, people, nature and water and health, this paradigm is shifting. The international editorial team, consisting of researchers and professionals across several disciplines, leads the reader through theoretical aspects, evidence, illustrated case studies, risk assessment and a series of validated tools to aid planning and design before finishing with overarching planning and design principles for a range of blue-space types. Over 200 full-colour illustrations accompany the case-study examples from geographic locations all over the world, including Portugal, the United Kingdom, China, Canada, the US, South Korea, Singapore, Norway and Estonia. With green and blue infrastructure now at the forefront of current policies and trends to promote healthy, sustainable cities, Urban Blue Spaces is a must-have for professionals and students in landscape planning, urban design and environmental design. Open Access for the book was funded by the European Union's Horizon 2020 research and innovation programme under grant agreement No 666773
The Urban Caribbean in an Era of Global Change
by Robert B. PotterBased on the author’s first hand field research, this book addresses the twin processes of urbanization and globalization as they affect the contemporary Caribbean region. One of the key aims of the book is to focus attention on the fact that contrary to popular perceptions, the Caribbean is highly urbanized. Indeed statistics show that the region is more highly urbanized than the world taken as a whole. In addition, the fact that the Caribbean region has always been affected by processes of globalization, in respect of its economy, polity and society, is central to the text. The chapters cover pressing topics such as urban change and the evolution of mini-metropolitan regions, the importance of the mercantile and plantopolis frameworks, tourism, post modernity and the urban nexus, economic change and the dual processes of global convergence and divergence, and the nature of the relationships existing between the state, the informal sector, housing and environmental conditions. In reality, it is shown that the development of tourism and enclave manufacturing is leading to new forms of urban concentration, and not spatial dispersal.
