Progress in Planning最新文献

The global population has rapidly urbanized over the past century, and the urbanization rate is projected to reach about 70% by 2050. In line with these trends and the increasing recognition of the significance of cities in addressing local and global challenges, a lot of research has been published on urban studies and planning since the middle of the twentieth century. While the number of publications has been rapidly increasing over the past decades, there is still a lack of studies analyzing the field's knowledge structure and its evolution. To fill this gap, this study analyzes data related to more than 100,000 articles indexed under the “Urban Studies” and “Regional & Urban Planning” subject categories of the Web of Science. We conduct various analyses such as term co-occurrence, co-citation, bibliographic coupling, and citation analysis to identify the key defining thematic areas of the field and examine how they have evolved. We also identify key authors, journals, references, and organizations that have contributed more to the field's development. The analysis is conducted over five periods: 1956–1975 (the genesis period), 1976–1995 (economic growth and environmentalism), 1996–2015 (sustainable development and technological innovation), 2016–2019 (climate change and SDGs), and 2020 onwards (post-COVID urbanism). Four major thematic areas are identified: 1) socio-economic issues and inequalities, 2) economic growth and innovation, 3) urban ecology and land use planning, and 4) urban policy and governance and sustainability. The first two are recurring themes over different periods, while the latter two have gained currency over the past 2–3 decades following global events and policy frameworks related to global challenges like sustainability and climate change. Following the COVID-19 pandemic, issues related to smart cities, big data analytics, urban resilience, and governance have received particular attention. We found disproportionate contributions to the field from the Global North. Some countries from the Global South with rapid urbanization rates are underrepresented, which may have implications for the future of urbanization. We conclude the study by highlighting thematic gaps and other critical issues that need to be addressed by urban scholars to accelerate the transition toward sustainable and resilient cities.

The Covid-19 pandemic has been presented as a critical change driver for rural amenity areas, precipitating urban flight and a decentralisation of housing choice and investment. House prices in both near-urban and more distant rural markets saw considerable growth in 2020 and 2021, linked to a mix of second home investment, expanded demand for holiday letting, migration to exploit flexible-working opportunities, and homebuying for early retirement. These demand-side pressures, apparently accentuated by the pandemic, combine with supply-side constraints on development in rural areas (which can accommodate a limited amount of additional housing) to produce significant housing stress. However, processes affecting some areas, in different parts of the world, have arguably been generalised to all areas, and localised processes remain under-investigated. This monograph explores the experience of the Brecon Beacons National Park in Wales, UK – an amenity area with good connectivity to a number of major urban centres and therefore sources of extra-local housing demand. Focusing on second home buying, as a leading element of extra-local pressure in amenity areas, the monograph considers the particular circumstances of this area. It shows that a combination of amplified demand-side factors, linked to the pandemic, and heightened supply-side constraints, due to a phosphate crisis affecting the National Park’s major river catchments, requires a programme of actions that extends beyond the housing domain in order to resolve escalating housing market challenges and associated community and economic risks.

This paper discusses the results of the “SavingScapes” research project that examined the role and relevance of civil society in landscape and heritage conservation, comparing Girona in Spain and Genoa in Italy. These two sub-regional areas are both on the Western Mediterranean coast. Tourism and international trade are the main drivers of development. Landscape is an important asset. In both areas, strong and constant transformative pressures and deeply rooted place attachment clash in the form of environmental protest movements or ‘social mobilizations’. Nevertheless, there are significant differences in the approaches and results of these mobilizations in the two areas. In order to assess the impact of these mobilizations on local planning and projects, the study has developed an outcome-based taxonomy with seven different categories, ranging from defeat (= no relevant impacts occurred) to sustainable plan/policy prefiguration (= cases in which mobilizations have led to the emergence of an alternative project). This taxonomy has then been applied to seven territorial conflicts in both case studies. Research shows that the impact of mobilizations may not be immediately significant in either region (always taking into account the differences between them). However, these movements have led to the development of novel approaches of dealing with the changing context and have emerged as co-partners in the process of constructing social and local identity.

Faced with acute housing crises, some governments are inclined to strip away the ‘bureaucracy’ of planning, relaxing rules on the scrutiny of planning applications and seeking to accelerate the building of new homes. The planning that remains becomes a ‘client service’ for the development industry – a system of housing licensing that follows on from a basic consideration of legal compliance. Such a system has been introduced in England, rooted in the extension of permitted development rights (PDR) for office-to-residential conversions. This article examines the determinants of housing quality through the conversion process, comparing the deregulated approach to conversion in England with Italy’s regulated approach, set within its zonal planning system. The conclusion drawn, after the examination of case studies, is that good quality housing cannot be delivered from the conversion of buildings without either the retention of strong case-by-case planning control or a much more detailed prescriptive approach to housing standards, which would have halted the majority of recent office-to-residential conversions in England.

Recent decades have seen the emergence of hybrid models of living and working associated typologies. These developments have been analysed from the perspective of different disciplines, each with their own interpretation of this phenomenon. Planning and architecture have addressed hybridization as a specific form of interaction between spatio-functional features (such as mixed use, multi-functionality and flexibility) and social features (such as formal and informal interactions and the spontaneous appropriation of spaces) or have sometimes simply focused on the spatio-functional dimension in urban spaces. Studies from other disciplines (e.g. mobility networks, transportation, sociology and information technology) have shown that hybrid spaces cannot exist without access to digitalization technologies. Such technologies are accelerating hybridization processes. This study examines the complex and layered phenomenon of hybridization as a possible combination of (or interaction between) spatio-functional, social and digital features within the planning debate and related fields. Most of the case studies explored by scholars so far have focused on interactions occurring between residential, social and recreational functions, but working functions are playing an increasingly important role. Furthermore, the COVID-19 pandemic has accelerated the development of new forms of hybridity in cities. As a consequence, the rising use of hybrid (on-site and on-line) working practices, planners, policy makers and stakeholders, as well as scholars, have increasingly discussed the concept of hybridization. In this context, various hybrid typologies of urban spaces have materialized in forms such as new working spaces (NWS) which include co-working spaces, incubators, as well as some cafés and multi-functional public libraries, which have recently provided working spaces. This paper focuses on the evolving concept of hybridity from the planning perspective. Based on five hybrid NWS including their surrounding neighbourhoods in Oslo, it provides empirical evidence for an understanding of the phenomenon that may support the development of hybrid spaces and buildings and develops suggestions for planning strategies.

Capital cities form the focus of a sub-field in urban studies. Much of the literature concerning their planning concentrates on their histories, and on the core precincts in which these cities of power often focus their governmental functions. Lacunae in the capital city literature include little attention to twenty-first century capital city settings in large, complex and expanding city-regions; to recent developments in broader urban literatures/city studies; and to contemporary directions of their planning and emergent futures. This article seeks to contribute to filling these gaps through a comparative study of five national capital city-regions on four continents: those of Delhi, Beijing, Paris, Pretoria and Brasília. The methods applied rest on secondary sources as well as some primary research in each of these city-regions. The article proceeds through a substantial review of literatures on capital cities and relevant urban studies, and sets out a general comparison of the five city-regions historically and in terms of their current features. We then proceed to an examination of present challenges and planning approaches in each city-region in turn. A discursive conclusion explores possibilities for the future and argues that by ‘catching up’ conceptually to contemporary trends, including debates around ‘extended urbanisation’, capital city studies, as a sub-field of urban scholarship, could play a useful role in promoting critique of policy and planning responses.

The COVID-19 pandemic highlighted the need for decision-support tools to help cities become more resilient to infectious diseases. Through urban design and planning, non-pharmaceutical interventions can be enabled, impelling behaviour change and facilitating the construction of lower risk buildings and public spaces. Computational tools, including computer simulation, statistical models, and artificial intelligence, have been used to support responses to the current pandemic as well as to the spread of previous infectious diseases. Our multidisciplinary research group systematically reviewed state-of-the-art literature to propose a toolkit that employs computational modelling for various interventions and urban design processes. We selected 109 out of 8,737 studies retrieved from databases and analysed them based on the pathogen type, transmission mode and phase, design intervention and process, as well as modelling methodology (method, goal, motivation, focus, and indication to urban design). We also explored the relationship between infectious disease and urban design, as well as computational modelling support, including specific models and parameters. The proposed toolkit will help designers, planners, and computer modellers to select relevant approaches for evaluating design decisions depending on the target disease, geographic context, design stages, and spatial and temporal scales. The findings herein can be regarded as stand-alone tools, particularly for fighting against COVID-19, or be incorporated into broader frameworks to help cities become more resilient to future disasters.

The purpose of this paper is to reveal possible reasons for unfavorable decisions in transit planning that weaken the possibility of increasing transit competitiveness versus the private car. The paper is based upon a qualitative case study of two Norwegian cities that have initiated projects to increase transit competitiveness versus the private car. Interviews and document studies have been conducted and interpreted using existing theories and case studies to determine possible reasons for decisions that are unfavorable for transit competitiveness. In this paper, it is concluded that conflicting politics is the main reason for unfavorable decisions in transit planning. Though the planning practitioners in the transit projects make effort to communicate to the politicians how the conflicting politics are limiting the possibility to increase transit competitiveness versus the private car, this effort has little effect. It is suggested in this work that the role of the urban planner should be extended to not only inform but also awaken a need for more knowledge among politicians and decisionmakers to help prevent unfavorable decisions being made within transit, and urban planning.
