ABSTRACT

Urban Living Labs (ULL) are considered spaces to facilitate experimentation about sustainability solutions. ULL represent sites that allow different urban actors to design, test and learn from socio-technical innovations. However, despite their recent proliferation in the European policy sphere, the underlying processes through which ULL might be able to generate and diffuse new socio-technical configurations beyond their immediate boundaries have been largely disregarded and it remains to be examined how they contribute to urban sustainability transitions. With this study, we contribute to a better understanding of the diffusion mechanisms and strategies through which ULL (seek to) create a wider impact using the conceptual lens of transition studies. The mechanisms of diffusion are investigated in four distinct ULL in Rotterdam, the Netherlands and Malmö, Sweden. The empirical results indicate six specific strategies that aim to support the diffusion of innovations and know-how developed within ULL to a broader context: transformative place-making, activating network partners, replication of lab structure, education and training, stimulating entrepreneurial growth and narratives of impact.  相似文献

Within the debates about the socio-economic advantages of cohesive urban regions, several barriers to institutional integration are said to exist, especially when a metropolitan government is absent and integration relies on inter-municipal cooperation. Some barriers are associated with different urban region structures, such as the asymmetric power relations and sociocultural contrasts between municipalities in systems with dominant core cities, or the lack of a leading city to overcome fragmentation and provide a shared identity in polycentric urban regions (PURs). This paper investigates whether urban regions formed around second-tier cities, whose features depart from both dominant core and PUR models, are able to mitigate these barriers when pursuing integration strategies. The analysis relies on interviews with municipal leaders in three representative European case studies, examining how they perceive the barriers to inter-municipal relations in second-tier urban regions. The findings show that perceptions vary not only between regions, with the three cases following different trajectories of integration, but also within regions, according to the geographical and socio-economic context of municipalities and the legacy of past relations. In general, barriers to integration are not minimized without explicit efforts to rebalance power relations, approach political cultures, mobilize core city leadership and develop a metropolitan identity.  相似文献

21世纪以来,西方城市研究界认为大部分城市发展将发生在发展中国家,新的城市理论也将产生在这些新的地理空间,而城市非正规性是其主要特征。本文首先对城市非正规性的演变进行了梳理,认为城市非正规性的研究具有对\"二元主义\"的超越,\"传统\"非正规研究的超越和认识论上的转变3个特征,并明晰了城市非正规性的理论内涵是一种管治模式;其次,认为制度变迁和城市非正规性研究之间的焦距在于国家、地方政府、企业和个体等行动者之间的相互作用,在此基础上总结出了城市非正规性互补式、补充式和让步式3种主要类型;最后,从政治、社会和文化三个维度总结了非正规性在中国形成的根源,并提出非正规性可以理解成为中国城市发展的一种模式,非正规实践及非正规制度蕴含制度创新的启示。  相似文献

制度变迁与中国城市的发展及空间结构的历史演变   总被引:9,自引:2,他引:9  
胡军  孙莉 《人文地理》2005,20(1):19-23
我国的城市发展水平同经济发展水平的偏离,说明对城市发展及其空间结构演变分析不能仅局限在物质经济领域,需要我们寻求影响城市发展及其空间结构变化的新因素一制度因素,把制度作为影响城市发展及其空间结构的一个主要的变量,来对此加以解释。为此,本首先构建了“制度变迁一城市发展变化”的理论框架,然后用该理论从宏观和微观两个方面来检验1949-1998年间制度变迁对城市发展及其空间结构的影响。与西方国家的以市场经济为主要动力驱动型的城市发展模式不同,中国城市的发展及其空间结构的演变在很大程度上是制度变迁而诱致的结果。但不同的制度对城市数量增长、组织体系及空间布局和对城市空间结构演变的作用力度又不尽相同。改革开放后,由于制度变迁带来的激励作用,中国城市获得了快速发展,城市空间结构快速变化。但与此同时,中国城市化的发展水平与相同发展条件下的世界城市化水平的差距却在拉大。而且随着市场经济体制的逐步完善,影响城市增长及空间结构的演变力量的因素越来越趋于分散化,制度变迁对城市发展所带来的激励作用正在弱化。为适应新世纪我国城市发展的战略目标,需要进行体制创新,为中国城市的发展及其空间结构的演变提供新的制度支持。  相似文献

Cities raise major challenges and opportunities for achieving sustainability. Much literature on urban sustainability focuses on specific aspects such as planning practices, urban policy or the diffusion of more sustainable technologies or practices. However, attempts at understanding the mechanisms of structural change towards sustainability have resulted in the emergence of an interdisciplinary field of sustainability transitions research. Transitions research has developed a phase model of transitions in which predevelopment, take-off, acceleration and stabilization phases are distinguished. However, the acceleration phase has received limited attention so far. This is a crucial gap as policy-makers are keen to accelerate transitions. This paper aims to enhance our understanding of how local actions contribute towards accelerating urban sustainability transitions. It does so by testing an acceleration mechanisms framework through exploring the collective agency of local initiatives in urban sustainability transitions. Drawing on a case study of the city of Brighton and Hove (UK), the paper finds that despite favourable local political conditions, there is a lack of evidence of acceleration apart from in individual domains such as food or mobility. Progress is found to depend on the agency of initiatives to both scale up sustainable practices and embed these practices into local governance arrangements.  相似文献

American cities vary considerably in the degree to which they pursue sustainability. What explains this variation? One plausible cause of such differences is that sustainability may be more appealing to high‐income cities than to more economically challenged cities. Yet such strict economic determinism seems simplistic and removes politics from an inherently political process. The hypothesis here is that any such relationship between income and commitment to sustainability is conditioned by a city's level of environmental advocacy. The data utilized in this analysis are derived from two large‐scale data sources. One is a comprehensive inventory of sustainability programs and policies in 50 large American cities. The other is a set of surveys in those same 50 cities. The multivariate model supports the hypothesis. Controlling for income growth and the predisposition of policymakers to be supportive of sustainability (as well as other alternative explanations), a city's commitment to sustainability is strongly linked to the advocacy of environmental and sustainability groups in the policymaking process. The example of Sustainable Seattle is used to illustrate the linkages that would seem to underlie the statistical analysis.  相似文献

ABSTRACT

Local sustainability initiatives are studied from two scholarly perspectives: the perspective of sociotechnical innovation, which relates to the capacity of bottom-up initiatives to contribute to the development of sociotechnical alternatives; and the perspective of civic engagement which relates to the capacity of citizens to organize themselves in order to pursue community goals. This paper argues that taking both these perspectives into account overcomes the problem of being too instrumental or the problem of neglecting the role of technology and innovation in local initiatives. The perspective of sociotechnical innovation presents different types of innovation pursued by local initiatives: the creation of new technology, the application of existing technology and the development of social innovation. Furthermore, innovations might diffuse over wider society by: replication, scaling up, and translation. In turn, civic engagement may take the shape of: the strengthening of social capital, the formation of social movements, and the substitution of functions and services. The insights from literature are illustrated and qualified by applying them in the context of concrete local initiatives. Finally, local initiatives will be portrayed as social contexts that are successful in gathering actors with different motivations and world views and that may contribute to the democratization of innovation.  相似文献

The aim of the paper is to define a set of smartness and sustainability indicators applicable to European cities and to assess their outcome in an ex ante perspective with regard to the implementation of Europe 2020 strategy. Following the DPSIR (Driving forces, Pressures, State, Impact, Response) model, we select a bundle of indicators for three relevant sustainability domains (environmental, social and cultural), which are proper to the smart city definition. Then we define groups of homogeneous cities for each domain by using a two-step cluster analysis. Results show the existence of heterogeneous groups of cities that are likely to become smart in the cultural domain, side by side with groups of more developed urban areas that have acquired a substantial advantage in the environmental and social dimensions.  相似文献

Non-urbanized areas (NUAs) play an important role in reducing the effects of climate change by providing both carbon storage and sequestration. Urban areas are responsible for the emission of 60% of global greenhouse gas, 50% of which are produced by buildings. During the past decades, increasing urban growth and sprawl processes produced several urban layouts characterized by different morphological features and a common lack of sustainable energy and environmental solutions. Investigating the relationship between urban morphology, energy demand and carbon emission/sequestration represents a relevant topic for urban planning practices implemented to face urban climate change effects. This study proposes a method for a transformability assessment aimed at investigating the transformation suitability of different urban morphology types. The case study is the metropolitan area of Catania (Italy), characterized by an impressive urban growth since the 1960s. The proposed method identification of limits and options for increasing sustainability of urban areas considering the contribution of both NUAs and built-up areas. This approach allows to identify appropriate planning tools for new layouts of urban fabrics while increasing the objectivity of the decision process. In the framework of climate change mitigation and adaptation, the outcomes of this research may lead to innovative urban planning practices.  相似文献

The emerging profession of arboriculture has influenced Australian urban landscapes over the past decade. Arborists manage the urban forest as a core component of urban sustainability. We analyse qualitative interviews with 53 professionals involved in tree management in six eastern Australian cities to determine the ways in which a concern with risk management has shaped both the urban forest and the professional status and role of arborists. We found tree‐related risk has, in part, worked against urban greening by reducing tree size. However, an emerging risk culture has encouraged the development of the profession of arboriculture, which, in turn, has pioneered sophisticated ways, familiar to neither engineers nor ecologists, of ensuring the cohabitation of people and trees.  相似文献

The state of archaeological research on ancient cities is presented in three edited volumes, and our understanding of ancient urbanism is undoubtedly advanced. Some venerable questions are renewed, including how and whether ancient cities differ from modern ones. However, the chapters consist mainly of narrowly focused aspects of ancient cities, and there are few interconnecting themes running through each volume. Future investigations of ancient cities will depend on an engagement with modern urban and social theory and from new kinds of comparative studies.  相似文献

In the contemporary neoliberal urban dynamics, those agencies that are on the margin of society constantly disrupt the boundaries of civil representation and forge new institutional relations within the dynamics of urban governance. I explore how this process was enacted at the turn of the century in Barcelona, looking at two coeval social mobilisations: the lock‐in of undocumented migrants in the Iglesia del Pi (2001), and the project of las agencias at the Museum of Contemporary Arts (1999–2003), both of which unfolded in the central neighbourhood of Raval. The invasion of the boundaries of civil society emerges here as a double phenomenon—one that develops both within society and in relation to institutions, instituting new modes of urban politics.  相似文献

In this article, we survey a growing body of literature within geography and other intersecting fields that trains attention on what inclusive smart cities are, or what they could be. In doing so, we build on debates around smart citizens, smart public participation, and grassroots and bottom‐up smart cities that are concerned with making smart cities more inclusive. The growing critical scholarship on such discourses, however, alerts us to the knowledge politics that are involved in, and the urban inequalities that are deeply rooted within, the urban. Technological interventions contribute to these politics and inequalities in various ways. Accordingly, we discuss limitations of the current discourses around inclusive smart cities and suggest a need for a nuanced definition of ‘inclusiveness’. We also discuss the necessity to further engage with critical data studies in order to ‘know’ what we are critiquing.  相似文献

This paper discusses and illustrates the ‘knowledge turn’ in urban policy across Europe. We identify four manifestations of it: 1) widespread efforts to lure knowledge workers; 2) a growing involvement of knowledge institutes in urban development and planning processes, 3) an explicit ‘knowledge based’ approach to planning and the design of public space, and 4) efforts to underline a ‘knowledge city’ identity using all kinds of marketing and branding techniques.  相似文献

ABSTRACT

Currently little is known about how institutional arrangements co-evolve with urban experimentation. This paper mobilizes neo-institutional literature and recent urban experimentation literature as a framework to explore how and why institutional arrangements differ across urban contexts. Empirically the paper focusses on smart city initiatives in Amsterdam, Hamburg and Ningbo. These three cities are frontrunners in adopting a comprehensive smart city agenda, but they do so in different ways. The paper examines regulative, normative and cognitive elements of institutional arrangements, explores how they shape experimentation, and reflects on their place-based specificities. The comparative analysis suggests that the focus of, and approach to, experimentation can be understood as resting in a (possibly unique) combination of strategic agency and dynamics at multiple spatial scales.  相似文献

Recent public debates about Australia's children and young people have begun to acknowledge the direct impact of urban development on their health and well-being. This paper reviews a broad range of trans-disciplinary literature addressing child-friendliness in contemporary Australian cities, drawing particular attention to the fact that even some of the most recognised texts on children and young people in Australia still make few references in their analysis to the issue of place and neighbourhood. More specifically, the paper points to two particular research challenges confronting the ongoing study of young people's well-being in urban areas, including (a) the need for a more thorough analysis, both conceptual and applied, about how children and young people's well-being is affected by different urban forms and by the social and ecological variations that occur throughout cities; and (b) the focus on younger children needs to be complemented by a focus on adolescents and young adults who in turn need to be actively involved in confronting these challenges.  相似文献

To contribute effectively to academic discourse on urban sustainability, disciplines need to think outside their silos and work together more collaboratively. Although straightforward to posit in theory, the practical realities of bringing together people with different worldviews, languages and skills can be frustrating and lead to loss of motivation. This paper presents the findings from a qualitative study of interdisciplinary team working on an urban sustainability project. Through analysis of archival materials, observations and interviews, a major theme of motivation was uncovered and explored. We conclude with some suggestions for working more effectively interdisciplinary, urban sustainability projects.  相似文献
