This article outlines the significant role of ideologies and values that lie beneath the physicality of the city, in reforming urban spatial morphology within a framework of social sustainability. We focus on the urban morphology of Middle Eastern cities, which have evolved within the framework of Islamic tradition, to illuminate the relationship between the ideological and physical dimensions of spatial morphology in all urban contexts. We examine the process by which a collective of religious, political, and cultural values underlying the physicality of the city have evolved into aesthetic conventions. This process played a crucial role in the maintenance of social and urban sustainability. We propose a form of “pattern language,” here termed the anatomical approach, that brings together the ideological dimension of a city's inhabitants and the physical characteristics of urban morphology. Such a model may help urban designers and architects to understand and create more responsive and friendly cities. It furthermore contributes to the planning education process by providing the essential knowledge and analytical foundation for site analysis and conservation of valuable contexts.  相似文献

Peru today is one of the main staging grounds for a continent‐wide integration effort. Launched in 2000, the Initiative for the Integration of Regional Infrastructure in South America (IIRSA) calls for an enormous expansion of the continent's transport and energy networks and an effort to increase the region's economic competitiveness. Among its most controversial projects is the Interoceanic Highway linking western Brazil with the Pacific coast of Peru. The highway has attracted fierce criticism from NGOs who point to major environmental impacts, an inadequate mitigation process, and a lack of transparency in funding flows and decision making. In an effort to voice their concerns, these groups engage the idea of ‘environmental governance’ to increase public participation in the development process and promote ecological sustainability. This alternative framework in turn opens up space for ‘environmental citizenship’. This article takes a closer look at how Peruvian NGOs employ this idea and suggests that while the group's advocacy of governance has had success, the building of environmental citizenship will require a move beyond urban Peruvian NGOs as technical experts.  相似文献

One often‐highlighted contemporary phenomenon in the pharmaceuticals industry is the use of “tiered pricing”, where essential medicines are sold more cheaply in low‐income than high‐income countries to widen access. With economists having for decades championed the applicability of such pricing to pharmaceuticals, this could be interpreted as a textbook case of “economic performativity”—the economic world increasingly conforming to economic models. In reality, however, tiered pharmaceutical pricing remains rare. Yet this article nonetheless urges retention of the performativity concept, albeit suitably reworked. For, insofar as the industry demonstrates nominal commitment to the model and to the social principles associated with it, it performs valuable political work. Moreover, it does help perform the pharmaceutical economy, by reproducing it in its existing form: repeatedly questioning the model's workability, Western manufacturers are able to continue to avoid putting it widely into practice and, in the process, jeopardizing the profits generated by conventional pricing.  相似文献

This article examines the urban development of Moscow from 1992 to 2015, arguing that the city's recent transformation from grey asphalt jungle to a “city comfortable for life” is driven by a process of neoliberal restructuring. In particular, the study finds that a set of multi‐scalar dynamics—namely, the global financial crisis, the rise of a local protest movement, and an intensified rivalry between federal and Muscovite elites—were the key driving forces behind Moscow's current evolution. The work advances a conceptual framework of neoliberal urbanisation that enhances the literature on post‐socialist cities and, more generally, the broader debate on actually existing neoliberalism.  相似文献

North American cities have undergone dramatic changes over the last century. Locations that were once inconvenient have become accessible through extensive road networks leading to population decentralization from the traditional urban centre to suburbia, creating polycentric sprawls from once monocentric communities. Hamilton, Ontario is one such city. The decentralization and urban decline of the city is widely attributed to sprawling development. This change in the sociospatial structure creates challenges for transportation planners as we see greater automobile dependency, greater commuting distances and increased congestion. Smart growth policies such as urban residential intensification (URI) aim to increase population densities in the urban core. This exploratory study estimates the benefits of such policies from a transportation aspect. It is predicted that the City of Hamilton will experience household growth of approximately 80,000 households over the period 2005–2031. Using IMULATE, an integrated urban transportation and land‐use model, a variety of development scenarios model this anticipated growth. Changes in vehicular emissions, traffic congestion and energy consumption as a result of URI are examined. Models of the land‐use/transportation relationship demonstrate how increasing population densities within a city's urban centre drastically reduce congestion, emissions and gasoline consumption.  相似文献

Abstract: After almost 30 years of Federal retraction from anti‐poverty initiatives, many American cities have been left with the dual burden of intensified poverty and far fewer resources to combat the problem. At the same time, such devolution has afforded cities the authority to forge poverty policy at the local level, such that the familiar neoliberal imperatives of state retraction and the mobilization of territory for capitalist expansion are frequently tempered by more progressive political imperatives at the local scale. What has thus emerged is a deeply ambivalent policy landscape, of which “kinder and gentler” poverty management strategies are a central feature. Using the example of a recent homeless program in San Francisco, “Care Not Cash”, this paper argues that such poverty management strategies, while less punitive than their revanchist predecessors, nonetheless introduce a new set of exclusions to the service delivery system, many of which are obscured by the language of compassion. In order to illustrate those new exclusions, I describe the city's homeless geographies—the public spaces, shelters, service sites, and housing models—that have been produced and reconfigured according to a logic of managing homelessness through the provision of care.  相似文献

Constructing Water Shortages on a Huge River: The Case of Shanghai   总被引:1,自引:0,他引:1       下载免费PDF全文
Shanghai is located on the world's third largest river (by volume). Yet it faces the risk of shortages of drinking water. Many decisions and environmental characteristics have contributed to this threat. First, Shanghai has become dependent on water brought into the municipality by rivers. Second, it has become increasingly reliant on water from the Changjiang (Yangzi River), principally in order to control the levels of pollution in the water that enters its treatment plants. Third, for reasons associated with inter‐provincial administrative arrangements, the city's water intakes are located within the municipality, within the estuary zone and subject to tidal intrusions of salt water. Fourth, at high tide and when the Changjiang's discharge is low, salt intrudes far into the estuary, beyond the current water intakes. If sea levels rise, these intrusions will become more pronounced. Fifth, large‐scale central government infrastructure projects (such as dams and the South‐North Transfer) are altering the hydrological characteristics of the river. Such projects raise the probability of salt water intrusions into the water intake zone. The Shanghai and central governments have thus made a series of decisions that, taken together, have led the municipality to rely on a source of drinking water that is increasingly unreliable and subject to the risk of shortages due to salt water intrusions. Why these decisions have been made – independently – is an important problem for those who would understand the provision of water for cities and the practical efficacy of Chinese governance systems.  相似文献

The early 21st century witnessed a boom in green building in San Francisco and similar cities. Major downtown property owners and investors retrofitted office towers, commissioned green certification, and critically, explored how greening might pay. Greening initiatives transcend corporate social responsibility: they represent a new attempt to enclose and speculate upon “green” value within the second nature of cities. However, this unconventional resource discovery requires a highly partial view of buildings’ socio‐natural entanglements in and beyond the city. I illuminate these efforts and their obscurities by exploring the experience of an exemplary green building in San Francisco, an office tower that has successively served as a headquarters organizing a vast resource periphery in the American West, a symbol and driver in the transformation of the city's own second nature, a financial “resource” in its own right, and most recently, an asset in an emerging global market for green property.  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

While the illumination of streets by electric streetlights in Western cities is a given today, in the early part of the twentieth century it was a technology whose conspicuous consumption was a status symbol for both individuals and towns. Not long after its introduction, however, electric lighting in cities also became noticeable in its absence. This paper draws on municipal records to consider how ideologies of white supremacy and progress came together to produce the uneven deployment of streetlighting in the small town of Rocky Mount, North Carolina, thus contributing to the city's segregation in the early part of the twentieth century. By tracing the development of hierarchical streetlighting systems, such as General Electric's White Way, I also show how the racialized deployment of streetlighting was aided by large electrical equipment manufacturers. In conclusion, I argue that these insights are crucial to understanding how technologies racialize space, but also how technologies such as streetlighting are central to the production of the spaces in which race is produced and racism takes place.  相似文献

‘Consumption’ is a central concept in the global environmental sustainability agenda. However, one important argument from Agenda 21 — that all social actors must now practise ‘sustainable consumption’— has been publicly and politically marginalised in high‐income countries such as Australia. Geographers potentially have a role in bringing consumption back onto the agenda by constructing a critical geography of consumption. Such research can help understand how the contextual use of natural resources is perceived and practised, and how consumption helps to shape contemporary social relations. This body of knowledge is vital for building sustainable development into everyday lives. Yet a focus on urban consumption perceptions and practices appears somewhat lacking in Australian geography. Ways forward can be drawn from international geography, such as in the United Kingdom where a substantial body of work has drawn a complex picture of contemporary consumption and environmental understanding. It has also challenged prevailing ‘ecological modernisation’ policy approaches, which ignore consumption's cultural facets. In sum, considering consumption in Australia can offer insights into cultural practices expressed through consumption; can challenge and add to European geographical literatures, and can also contribute to sustainability debates by offering alternatives to currently ineffective policy discourses.  相似文献

More and more European cities are confronted with population decline in a structural sense. This development of “urban shrinkage” has different causes, but similar effects: the city's hardware, software and mindware deteriorate. In this paper, we explore and assess policy strategies to respond to urban shrinkage in a European context. Four strategies are identified: (1) trivializing shrinkage, (2) countering shrinkage, (3) accepting shrinkage and (4) utilizing shrinkage. We suggest that accepting shrinkage by improving the quality of life for the city's existing residents is the most suitable and sustainable strategy. Dealing with shrinkage is a complex urban governance process that asks for a mental transformation from growth to shrinkage as well as regional rather than local thinking. Moreover, due to the fiscal burden of shrinkage, city governments will be increasingly dependent on the willingness of citizens to help. Civic engagement, however, is not something that can be simply dictated. Therefore we conclude that the authorities of Europe's shrinking cities should first enable their citizens to care for their community before asking them to do so.  相似文献

The arrival of Anglo‐American forces in Naples on 1 October 1943 precipitated the structural crisis which had beset the capital of the south since its integration into the Italian nation‐state in 1860. This crisis had been masked by the reassuringly engaging ethos of napoletanità, encoded in the urban dialect and crystallized in its literary culture from Matilde Serao and Salvatore Di Giacomo onwards. The myth of napoletanità had been frozen under Fascism, but was shattered by the experience of the war years and after, and only factitiously restored under the political hegemony of the monarchist ship owner Achille Lauro during the 1950s. Young literary Americans such as John Home Burns and William Weaver, who found themselves in Naples with the occupying Allied forces, fell under its spell, while the equally young British military intelligence officer Norman Lewis maintained a detached, but sympathetic, objectivity. The older Tuscan writer, Curzio Malaparte, so provocatively transformed the image of Naples as to earn furious rejection by the city's dominant postwar political circles and by Italy's literary circles. Yet, despite brilliant attempts at restoration by the departed Neapolitan, Giuseppe Marotta, and the much‐loved actor‐playwright Eduardo De Filippo, napoletanità was systematically undermined and demolished by younger Neapolitan writers from Domenico Rea and Anna Maria Ortese to Raffaele La Capria as the city's urban fabric was transformed by appallingly irresponsible property speculators. This article focuses on the literary anthropology of Naples in the 1940s. It explores literary texts and contexts, and the way they problematize Naples as a unified subject or object. It addresses the paradoxical issue of the city's need for liberation from itself, and the time scale of a liberation that perhaps has always been and always will be in fieri.  相似文献

More than ever before, analysts in government have access to policy‐relevant research and advocacy, which they consume and apply in their role in the policy process. Academics have historically occupied a privileged position of authority and legitimacy, but some argue this is changing with the rapid growth of think tanks and research‐based advocacy organizations. This article documents the findings from a randomized controlled survey experiment using policy analysts from the British Columbia provincial government in Canada to systematically test the source effects of policy research in two subject areas: minimum wage and income‐splitting tax policy. Subjects were asked to read research summaries of these topics and then assess the credibility of each article, but for half of the survey respondents the affiliation/authorship of the content was randomly reassigned. The experimental findings lend evidence to the hypothesis that academic research is perceived to be substantially more credible than think tank or advocacy organization research, regardless of its content. That increasingly externalized policy advice systems are not a pluralistic arena of policy research and advice, but instead subject to powerful heuristics that bureaucrats use to sift through policy‐relevant information and advice, demands added nuance to both location and content‐based policy advisory system models.  相似文献

Cities offer a large menu of possible employment and leisure opportunities. The gains from such consumer city leisure are likely to be lower on more polluted days. We study the association between daily consumption activity and outdoor air pollution in China and find evidence in favor of the hypothesis that clean air and leaving one's home for leisure trips are complements. Given the high levels of air pollution in cities in the developing world, regulation induced improvement in environmental quality is likely to further stimulate demand for the consumer city.  相似文献

China's South–North Water Transfer Project (SNWTP) is a vast and still expanding network of infrastructure and institutions that moves water from the Yangtze River and its tributaries to cities in North China. This article aims to assess the SNWTP's impacts by beginning to answer seven questions about the project: How is the management of the SNWTP evolving? What are the problems to be resolved when managing SNWTP water within jurisdictions? What are the status and management of water quality in the SNWTP? What are the consequences of resettlements caused by the SNWTP? How is increased water supply affecting regional development? Is the SNWTP achieving its stated environmental goals? What are the sustainability credentials of the SNWTP? Drawing on primary and secondary data, the article demonstrates both that the opportunities and burdens characterising the project are highly uneven and that management systems are evolving rapidly in an attempt to enforce strict water quality targets. Furthermore, while the SNWTP may be helping to resolve groundwater overexploitation in Beijing, it is highly energy intensive, raising questions about its sustainability. Our analysis highlights the need to continue to interrogate the socio‐economic, environmental, and political implications of such schemes long after they are officially completed.  相似文献

Abstract

The physical growth of cities is usually used to define the main direction of a city's development. This definition is key to understanding the city's current state and to plan for the future. Many urban planners agree that master plans should include historical urban growth and aim to specify the effective factors driving urban growth. However, defining urban boundaries and historical urban areas is a difficult task. The lack of satellite images, air photos, and real maps to use as base maps for historical urban studies is a problem that a researcher may face when determining patterns of urban development or conducting other analyses. In this article, the authors examine historical changes of the urban boundaries of the Ottoman city of Manisa. They analyze the physical growth of this large city by using the historical buildings (mosques, masjids, madrasas, baths, caravansary, and others) as markers.  相似文献

Controversy has erupted in Selma, Alabama, over recent efforts to commemorate the career of Nathan Bedford Forrest, a Confederate cavalry officer and founding member of the original Ku Klux Klan. More generally, the controversy in Selma is emblematic of an enduring regional pattern in which contests over the future are couched in terms of the past. Relative to other media, monuments appear to be trustworthy and lasting. Despite this appearance of historical consensus and stability, the city's public spaces are the product of and conduit for ongoing politics. The current conflict pits memorial activists associated with the Civil Rights Movement against neo‐Confederates. Interpreted in the context of Selma's increasing promotion of Civil Rights heritage and the recent election of the city's first African American mayor, the Forrest affair highlights the utility of the concept of symbolic accretion for understanding the complexities of commemorating antagonistic histories in the same place. Symbolic accretion describes the appending of commemorative elements onto already existing memorials. The situation in Selma suggests two different types of symbolic accretion, allied and antithetical. More generally, the act of commemoration itself may be understood as a process of accretion in that heretofore anonymous spaces are formally recognized via the grafting of memorial elements.  相似文献

An American geographer examines the recent economic resurgence of a historically significant city in China's interior as a result of a policy utilizing science and technology research institutions and the local labor force to "jump-start" technology-intensive growth. The study, based on a series of interviews and data gathered during field research in 2000 and 2002, reveals synergies among the city's pre-existing defense-related activities (electronics and aviation), its favorable financial and transport infrastructure, and the concentration of several large, prestigious technical universities, which have been utilized in the transformation of the city economy toward high-technology production for China's domestic market.

Australia's large regional cities and towns display wide variation in how they are adjusting to the socio‐economic transitions occurring in Australia. That variation is exposed using a multi‐variate model analysing performance on a range of socio‐economic variables over the decade 1986 to 1996 for 122 cities and towns with populations of 10 000 and above at the 1996 census. Those places are classified into seven clusters of community performance reflecting opportunity/vulnerability, and their spatial patterns are mapped. The resulting framework is then used to show how the recent geography of the socio‐economic performance of the large regional cities and towns has a distinctive selectivity and contributes to opportunity in some places and the vulnerable performance of others. The influence of that selectivity can be seen in the mismatched geographic patterns evident from an analysis of shares of national population and employment change, investment in non‐residential construction, levels of welfare dependency, and the ratio between household income tax generation and transfer benefits received. The paper uses the insights drawn from that analysis to pose questions suggesting the need to rethink national policy perspectives for addressing change in non‐metropolitan Australia.  相似文献
