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

Since 2010, the term “smart city” has become a buzzword, used in a vague way to denote the increasing integration of information technology into city management processes and to describe the social and community processes they enable. The adjective “smart” is, however, only applied to cities: by implication non-cities (i.e., rural and peripheral regions) are not smart. In this paper we describe how the term “smart city” is used, and show that processes similar to those that make cities smart also occur outside cities. Reserving the term “smart” for cities therefore reflects a bias, similar to the bias that associates creativity and innovation with cities. As geographers we have become aware of our colonial and sexist biases: in this paper we argue that our urban bias is alive and well, and call attention to it.  相似文献

Metropolitan cities are undergoing a major spatial and environmental transformation. The proliferation of business districts, corporate headquarters and international hotels is prompting a massive verticalization and densification of land use, which is affecting the urban environment and infrastructure in a number of ways. Nowhere are urban environmental pressures so accentuated as in Third World metropolitan cities. Here the rush to gain a competitive edge in the global economy, in order to attract multinational firms and become a ‘global city’, is leading to an inconsistent urban policy framework in which development policies frequently clash with environmental policies. This article explores the environmental complexity of Third World metropolitan cities, focusing on the cases of Beijing and São Paulo. After a conceptual review of the relationship between globalization, cities and urban environmental problems, it examines how globalization is prompting spatial and environmental transformations in both cities; looks at the dichotomy between development policies and environmental policies by analysing the instruments in place; and investigates the role of globalization vis‐à‐vis urban sustainability issues.  相似文献

Typical of the 1990s, the global cities phenomenon preceded the past decade’s massive spread of smart cities. Yet the question of how the two phenomena currently coincide remains to be considered, as well as an analysis based on viewing smart cities as global cities. An analysis related to the European scenario is developed in this article, aimed at giving a response to the previous considerations. An index is also proposed; concerning the global character of the cities, it considers the ability of the cities to attract Foreign Direct Investments (FDI). Results of the proposed analysis show that in Europe four main scenarios exist. Two regarding positive and negative correlations between the diffusion of global and smart cities, and another two scenarios demonstrate cases in which the two features are not correlated. The first two cases are respectively related to smart cities that are also global cities. The last two cases deal with the presence of different drivers that are not related to smart urban plans, which could, however, drive the attraction of FDI or which could also promote smart actions without the thrust of FDI. Correlation and regression analyses complement the work.  相似文献

City evolution is connected to social, economic and technological evolutions. New technologies induce further changes, which are highly innovative, which again affect the urban and territorial systems. The city once again adjusts to new opportunities in relation to information and communications technologies, energy and mobility. In this paper, smart city, configured as a set of interacting systems with people, is focused as a possible model to follow for pursuing sustainability in real cities of the twenty-first century. Three processes are recalled: city development, city planning theories and city rules. Smart city seems to be the convergent point for all processes evolving in European urban areas. Theoretical definitions of smart city are recalled. At the same time, the European Commission is promoting smart city rules for implementation. Moreover, in the last years some local decision-makers implemented specific measures that today can be considered in the class of smart city measures. The objective of the paper is to analyse the European perspectives for smart city, trying to separate the three processes that are strongly integrated, but without formal links. To verify the European smart city approach, a study case concerning city logistics is considered.  相似文献

Innovations in urban governance such as Urban Living Labs (ULL) are expected to accelerate the transition towards more sustainable and climate-resilient cities. This article reviews different ULL across Europe and explores the role and potential capacity of municipalities in the development of and/or facilitation of ULL as a form of experimental governance. It focuses on the role of the public sector in the multi-actor collaborations that often characterize experimental governance. The article draws on literature on cities in sustainability, climate and environmental governance, and bridges this with political science literature on governance. Based on institutional theory that emphasizes roles, identities, and perceived and actual acting space, three functional roles for the municipality are singled out – promoter, enabler and partner – in a framework with a set of indicators that are used to analyse 50 case studies of ULL (http://www.urbanlivinglabs.net). The aim is to advance knowledge on how municipalities can facilitate urban sustainability through experimental governance.  相似文献

Abandoned industrial sites, usually contaminated by hazardous substances, create social injustice in the surrounding communities. Redevelopment of industrial land has brought prospects of sustainable development to the communities that live in and around them. This research is to identify the critical factors facilitating urban regeneration and particularly social sustainability in Kaohsiung, an industrial city of Taiwan which experienced deindustrialization in recent decades, resulting in several abandoned industrial sites and decay of the adjacent urban communities. Two different industrial land redevelopment projects were examined; (1) Jhongdou Wetland Park, which focuses on environmental sustainability, and (2) Pier-2 Art Centre, which focuses on economic sustainability. Measured by the social sustainability indicators developed by the Oxford Institute for Sustainable Development and through findings from a questionnaire survey of community members, this study found that the redevelopment project of the Pier-2 Art Centre has a higher level of social sustainability than the Jhongdou Wetland Park, performing better in six out of nine themes. Critical dimensions resulting in the better performance in social sustainability of the Pier-2 Art Centre included rental affordability, heritage conservation, community image, cultural activity, community association, public space, local organization and higher accessibility to facility.  相似文献

This article reviews some issues reflected in the 1996 UN Habitat II agenda and recent research on urbanization. The themes of the 1996 Habitat conference were urban development, urban poverty, and governance, civil society, and social capital. It is expected that over 50% of total world population will live in cities in the year 2000. Cities are viewed both as engines of economic growth and centers of severe economic, environmental, and social problems. There is some disagreement about whether cities are rational economic structures or what the World Bank's urban agenda is and its relationship with macroeconomic policy. Discussions of global urban issues are criticized for their neglect of issues of equity and poverty, cultural diversity, and identity and representation. Habitat II also stressed urban sustainability. There is growing recognition that urban management involves more than the "Brown Agenda" of environmental and physical aspects of urban growth. Recent studies identify how politics and power affect people's access to basic urban services. Urban economic activity can also contribute to environmental problems. Urban growth affects the provision of health services. Although there is not a consensus on the role of cities in expanding economic and social development and the best management practices, there is sufficient evidence to indicate that urban processes are varied throughout the developing world. The links between urban and rural areas differentiate cities and expose the need to understand the role of intermediate urban areas surrounding and between larger cities. Poverty has become increasingly urbanized, but the extent of poverty is unknown. Habitat II was an unprecedented effort to engage nongovernment groups, local government staff, trade unions, and the private sector and to emphasize community participation. Networks of trust and reciprocity are key to solving poverty, inequality, and disempowerment problems.  相似文献

Previous environmental equity studies have examined the spatial distribution of aircraft noise across cities. Their findings show that, in several cities, visible minorities and low-income populations are most affected by aircraft noise. In contrast, one study concludes that well-off populations are the most affected. These contradictory findings support the use of a comparative approach for several cities. The aim of this study is twofold. First, we want to identify if there are groups in the population that are in a situation of inequity to aircraft noise exposure in Toronto, Montréal, Vancouver, and Calgary. Then, we want to check if the exposure to the aircraft noise of the different groups varies significantly from one metropolis to another. We use the recommended noise exposure contour maps in Canada: the Noise Exposure Forecasts. Next, four variables are extracted from the 2016 Statistics Canada census at a fine-scale level (dissemination areas): that is, the percentages of low-income, visible minorities, 0- to 15-year-old, and 65-year-old and over populations. The results of a mixed effects logistic regression model show that environmental inequities in terms of exposure to aircraft noise for the four population groups are not consistent from city to city.  相似文献

Sustainable development as a process towards sustainability requires collaboration among societal actors and stakeholders at multiple levels. A key issue is to provide them with that they have comprehensive and transparent knowledge base representing the state and trends of different dimensions of sustainability. This study addresses the need to analyse and present data of sustainability as a foundation for the sustainable development process within municipalities, and among them. As a case study, we focus on 18 municipalities in the crisis-struck Bergslagen region in Sweden and compare them with 101 surrounding municipalities. Data from 2001 and 2006 on 15 indicators representing ecological, economic and social sustainability criteria were transformed to a common scale through normalization around the median, and summarized. Bergslagen region municipalities performed poorer than the surrounding ones for all dimensions in 2006. The change from 2001 to 2006 was positive for economic and social criteria, while the ecological dimension developed negatively in all municipalities. We stress the need for municipalities to collaborate with each other and other actors both at municipal and regional levels, and to use sustainability indicators as a base for informed planning processes. We propose visualization of indicators using maps to support decision-making and social learning.  相似文献

The notion of transformation is gaining traction in contemporary sustainability debates. New ways of theorising and supporting transformations are emerging and, so the argument goes, opening exciting spaces to (re)imagine and (re)structure radically different futures. Yet, questions remain about how the term is being translated from an academic concept into an assemblage of normative policies and practices, and how this process might shape social, political, and environmental change. Motivated by these questions, we identify five latent risks associated with discourse that frames transformation as apolitical and/or inevitable. We refer to these risks as the dark side of transformation. While we cannot predict the future of radical transformations towards sustainability, we suggest that scientists, policymakers, and practitioners need to consider such change in more inherently plural and political ways.  相似文献

The authors apply longue durée and semiotic approaches to a case study of flood management in the American Midwest to critique the suggestion that naming the current geological epoch the ‘Anthropocene’ might encourage global environmental sustainability. It is unlikely that the Anthropocene moniker has the symbolic power to correct ecomyopia, which the authors define as the tendency to not recognize, to ignore, or fail to act on new information that contradicts political arrangements, social norms, or world views. Anthropogenic transformation of the Mississippi River watershed shifted world views toward the human domination of nature and afforded opportunities for social stratification and the consolidation of capital and control over resources, which has biased social responses to increasing flooding. Globally, biological systems have been replaced with technological systems of increasing complexity creating canalized trajectories of practice and thought in which societies become insulated from ecological realities. The global capitalist response to the Anthropocene will likely be to embrace technological hubris.  相似文献

In the aftermath of failed urban renewal projects and the decline of central cities, community gardens have become increasingly popular in urban planning, public health, and environmental circles. However, gardens still occupy a tenuous and contradictory position in the city. While urban gardens are bounded spaces, they are also dynamic places where different understandings of (agri)culture, land use, and belonging are enacted and contested. In this paper, we identify three distinct ways in which gardens in a small Midwestern city are used and experienced by refugee gardeners and local officials: the material garden, the imagined garden, and the community’s garden. The material garden, embodied in the biophysical aspects of the soil, seeds, and resources needed to cultivate plants, shapes what can grow in the garden and the transformations by refugee agricultural practices. While planners tend to see urban gardens as temporary spaces that can promote limited pathways of migrant incorporation, gardeners practice, and imagine gardening differently through social, cultural, and economic interactions. We argue that these practices challenge traditional understandings of nature and urban planning, and can promote inclusive understandings of agriculture, cities, and sustainability, embodied in the ideal of the community’s garden.  相似文献

Sustainability in the conservation of architectural heritage is now more extensively considered than it was decades ago. The introduction of the concept of sustainability to the field marked hopes to overcome problems threatening heritage sites. There are general concepts guiding sustainable conservation. However, heritage specifics play important roles in achieving sustainability, and may direct the formulation of sustainable concepts to be applied. This paper is an attempt to add to the discourse of heritage sustainability by discussing buildings managed through a tradition of Islamic waqf in the World Heritage Stone Town of Zanzibar. It examines sustainability in terms of its financial, social, managerial, and environmental aspects. The relatively good survival rate of waqf buildings in the old town over several centuries suggests sustainable and transmissible ‘genes’ within the tradition. Waqf was found to elaborate ways to strike a balance between heritage consumption and use, avoiding gentrification, and enabling collective urban conservation. It further suggests that sustainable conservation cannot avoid monetary sacrifices, and if it is to be sustainable in the long term it should be inherent in the heritage itself.  相似文献

The thesis here submitted for debate and criticism is as follows: if today's governing principles that inspire policy choices and priority setting in our societies (which claim to be "knowledge- based societies") are to remain in place in the course of the coming five to ten years, the relative position of the less developed regions (and cities) vis-à-vis the most developed ones will again deteriorate, even though per capita real purchasing power might also slightly increase in the less developed regions. The if-hypothesis, however, is not the only possible pattern of future developments. Because present economic and political leaders are, in general, the promoters and supporters of today's predominant principles, the only way to make possible alternative future developments based on solidarity, sustainability and democracy is that citizens themselves take the initiative, locally and globally, to modify present practices and define new goals and new priorities. In consideration of the results obtained in recent years by civil social movements and protests, one may reasonably consider it as a possible scenario.  相似文献

Urban sprawl has a major impact on the environment, public health and the socio-economic evolution of cities. The causes are numerous, being mainly related to the generalized use of the automobile in modern cities. Urban sprawl has been especially relevant in US cities since the 1950s, rapidly spreading to other cities in the rest of the world. This paper studies the case of Spain using recent data. Spanish cities have grown rapidly over the 90s and 2000s. The country has completed the process of urbanization and has suffered the effects of a major real estate bubble. In this context, we are interested in measuring and explaining where and why urban sprawl has appeared in Spanish cities. Digital mapping carried out around the year 2000 providing full coverage of Spain is used to calculate an Urban Sprawl Index. It is applied to all urban areas and municipalities throughout the country, providing an objective, comparable measurement of sprawl and identifying which areas are most affected by this phenomenon. A second stage of analysis is conducted in an attempt to explain the causes of the differences in sprawl among Spanish cities with a regression model based on the literature. We have found that the cases most affected by sprawl are the latest urban developments on the Mediterranean coast as well as certain areas in the vicinity of large cities: the mountains to the north of Madrid and the coastline near Barcelona and Valencia. In some cases, urban sprawl is starting to become a problem for the environment and urban sustainability, with important consequences for the future evolution of the affected cities.  相似文献
