This paper presents a case study of contemporary urban redevelopment in Syracuse, New York, within a theoretical framework drawn from urban political economy. Our analysis integrates the role of the local state in assuming the financial risk for a redevelopment project with an understanding of the meanings and role of a fabricated cultural landscape in ensuring the success of the project. We argue that the urban landscape is fundamentally embedded and implicated in the ongoing political economy of American urban places.  相似文献

The idea of urban fringe belts has been recognised as a powerful means of understanding the physical form of urban areas and the process of urban outward growth and internal change. Surrounding Auckland's city core, an inner fringe belt can be recognised. Farther out there are middle and outer fringe belts. Fluctuations in socio-economic development, the adoption of new transport modes, land reclamation and topography are major factors influencing the formation of these fringe belts. The examination of changes to fringe belts highlights important issues of urban transformation, which are pertinent to planning and design policies for urban landscape management.  相似文献

Abstract

Southeast Chicago's Calumet region is many things to many people. Home to wetlands and wildlife, mills and millgate communities, landfills and brownfields, it seems to defy easy characterization. This paper argues that it is the jarring juxtaposition of each of these features that best reflects the area. Ten interpretive “keys” -or significant landscape-shaping elements form an interpretive frame.  相似文献

Urbanization can profoundly influence the ecosystem service for biodiversity conservation. However, few studies have investigated this effect, which is significant for maintaining regional sustainable development. We take the rapidly developing, mountainous and biodiversity hotspot region, Jinghong, in southern Yunnan Province as the case study. An integrated ecosystem service model(PANDORA) is used to evaluate this regional BESV(ecosystem service value for biodiversity conservation). The modeled BESV is sensitive to landscape connectivity changes. From the 1970 s to 2010, regional urban lands increased from 18.64 km2 to 36.81 km2, while the BESV decreased from $6.08 million year-1 to $5.32 million year-1. Along with distance gradients from the city center to the fringe, BESV varies as an approximate hump-shaped pattern. Because correlation analysis reveals a stronger influence of landscape composition on spatial BESV estimates than the landscape configuration does, we conclude that the projected urban expansion will accelerate the BESV reduction. Of the projected urban land, 95% will show a decreasing BESV trend by approximately $2 m-2 year-1. To prevent this, we recommend compact urban planning for the mountainous city.  相似文献

Creative cities contribute much to the cultural economies and identities of a nation, shaping imagination and talent, and contributing to the sense of livability and place. Artists, designers, crafters, tinkerers, and even small-scale manufacturers are at the heart of urban rejuvenation in cities such as Brooklyn in New York, and Newcastle and Melbourne in Australia. Increasingly this activity is referred to in the public realm via the media, including social media, through the all-encompassing term ‘making’. Yet in much public policy, this activity is framed through previously held notions: artists, culture, and the precincts associated with this life. I explore this disjuncture by focusing on a case study of Australia’s largest city, Sydney, to interrogate the current schism between public and policy discourse. I share findings about the role of discourse, community consultation, and timing in policy development to argue that valuing making in cities requires commitment to continual community consultation to ensure policy currency, with makers as key stakeholders in this dialogue. Furthermore, the intersection of policy domains is required to prevent isolating making into one policy area. I highlight implications for the imagining of creative cities.  相似文献

以经济发达的宁波市区为例,通过水环境敏感性与水质现状两方面综合评价城市内部空间水环境效应,从中心城区至外围地区,因人口集聚水平、产业发展类型和水污染处理能力的差异,水环境效应指数不断降低;探究其空间异质性,各乡镇评价单元水环境效应指数存在正向相关;运用地理加权回归(GWR)模型,定量分析水环境效应影响机理,其中经济发展水平是水环境演变的基础,产业发展与人口集聚则是造成水环境压力的直接原因。人口空间集聚带来的水污染排放,产生的水环境效应远高于其它因素,是城市内部水环境下一步治理的重点。  相似文献

Most scholarship on rural–urban migration in Sub-Saharan Africa demonstrates that migrants tend to move in a “circular” fashion and only spend short periods of time in cities before returning home to rural villages. However, some scholars working on the impacts of climate change on migration suggest that deteriorating environmental conditions may undermine rural livelihoods and lead people to move to cities for longer periods of time. If this is true, then climate change threatens to accelerate urbanisation and lead to renewed stress on urban infrastructure. The purpose of this paper is to explore these positions and we do so by collecting survey [n = 241], in-depth interview [n = 75] and focus group [n = 123 participants] data from rural and urban Malawi. Two key results stand out as significant. The first is that migrants in Malawi's capital city tend to stay in the urban environment for longer periods of time than conventional understandings of migration would predict. The second key result is that climate change may actually lead, in the case of Malawi, to reverse (i.e urban–rural) migration. This is because many of the people in Malawi's cities depend on products produced in rural environments (e.g. food and fuelwood). If climate change undermines rural livelihoods, then many urban residents will find the basis of their livelihoods removed and will likely respond by moving back to rural villages. Overall, our results, therefore, suggest that in at least one case the effect of climate change on migration may not be to increase migration towards cities but to stimulate an exodus from cities and back to the rural countryside.  相似文献

Participatory scenario planning (PSP) processes rely on accurate stakeholder identification to develop a key set of critical uncertainties. While many stakeholder analysis methods are able to identify stakeholders and describe their relationships, we found these efforts to have limited use in the fast-moving and in-depth approach of PSP research. We find that social network analysis (SNA) is an efficient, objective, and transparent approach to stakeholder identification in highly contested natural resource management issues. We present a case study of our research on Alaska’s Kenai Peninsula to describe how SNA’s ability to contextualize the relations between actors can benefit participatory research.  相似文献

This article presents a methodology for a more detailed investigation of urban landscape change in rapidly growing cities of the less developed world beyond typical macrolevel approaches. This research is an attempt to bridge the gap between traditional landscape analysis and geographic information science (GIS). The article presents the preliminary results from a pilot project in Zamalek, Egypt, highlighting the benefits and drawbacks of the two techniques. Rarely used to study the less developed world, these techniques are utilized to assess change within a portion of Cairo's urban landscape. Large‐scale historic maps and high‐resolution satellite imagery, combined with field attribute collection, are the major data sources in this applied landscape analysis. A motivating factor in the desire to examine landscape change at such a large scale is the need to create monitoring systems for historic preservation in cities of the less developed world.  相似文献

This article argues that policy discourses need to be set within the heterogeneous resources that governments routinely use to govern across the state/non-state divide. It employs the governmentality perspective to show how a discursive coalition in the planning for housing sector uses such resources to embed a new rationality of 'planning for sustainability' in a host of differing local arenas. The article extends the governmentality approach by proposing that this 'embedding' process is geographically uneven as the discourse becomes enmeshed in differing economic and environmental circumstances. The analysis thus reveals a geography of governmentality by showing how local actions intrude upon the functioning of governmental networks.  相似文献

While the geomorphic structure of many landscapes is materially molded, shaped and transformed by human practices, it is at the same time experienced and perceived through the mediation of cultural discourse and representation. The objective of this article is twofold: (1) to establish a conceptual framework for integrated analysis of human and geomorphic dimensions of landscape change; and (2) to illustrate the use of this framework in the assessment of a physical system severely affected by human agency. This perspective offers one way in which human agency can be synthesized and integrated into aspects of physical geography— specifically fluvial geomorphology— from both a conceptual and a pragmatic point of view. The upper Embarras River in east central Illinois, used as a case study, has been and continues to be physically affected by the cultural practice of agricultural drainage over the past century and a half.  相似文献

This article examines the locational patterns of population and employment and the resultant changes in urban form in the Halifax–Dartmouth region between 1970 and 1996. The article employs the univariate and bivariate K function to measure spatial dependence or clustering within and between the classes of residential and commercial land parcels. The results of the K function estimates suggest that residential land parcels cluster together, commercial land parcels cluster together, and residential and commercial land parcels have become more clustered over time. Evidence of clustering provides insight into the changing urban form of the region and possible multinucleation.  相似文献
