Most research on the discourses and practices of urban regeneration in the UK has examined case studies located in areas of relative socio-economic distress. Less research has been undertaken on regeneration projects and agendas in areas characterised by strong economic growth. Yet, it is in such places that some of the best examples of the discourses, practices and impacts of contemporary urban regeneration can be found. In some areas of high demand regeneration projects have used inner urban brownfield sites as locations for new investment. With the New Labour government’s urban policy agendas targeting similar forms of regeneration, an examination of completed or on-going schemes is timely and relevant to debates over the direction that policy should take. This paper, drawing on a study of urban regeneration in one of England’s fastest growing towns, Reading in Berkshire, examines the discourses, practices and impacts of redevelopment schemes during the 1990s and 2000s. Reading’s experiences have received national attention and have been hailed as a model for other urban areas to follow. The research documents the discursive and concrete aspects of local regeneration and examines the ways in which specific priorities and defined problems have come to dominate agendas. Collectively, the study argues that market-driven objectives come to dominate regeneration agendas, even in areas of strong demand where development agencies wield a relatively high degree of influence. Such regeneration plays a symbolic and practical role in creating new forms of exclusion and interpretations of place.  相似文献

This paper investigates the dual nature of regionalisation between imposed institutionalised territoriality and self-made ‘ad hoc’ collaborative regional arrangements between localities. This involves, as the paper sets out to show, different, but concurrent imagineerings of ‘regions’ to two audiences - within and without a defined region. They are applied to the same territory, albeit with different images and sets of actors for internal (local) and external (national/international) consumption. These developments are examined within the context of the ‘new regionalism’ debate, in particular the notion of a replacement of ‘old’ through ‘new’ regionalism as a sequence. This duality of region making challenges the frequently somewhat simplistic presumption of regions forming as one complete entity, ‘out there’ to compete on a global market. They also have to fight for their recognition internally, but with different arguments, rationales and policies. This means that the possibility of overlapping single purpose ad hoc formed regions, as postulated under the new regionalism, needs to take into account the likelihood of several meanings of one and the same territory. The examples demonstrate that the two possibilities overlap - multi-territoriality and multi-meanings of (new) regionalism. The paper uses the example of post-unification eastern Germany, where in 1990 a completely new set of traditional regions was established, implementing a 1960s-derived western German model. Since this common starting point, strong economic, cultural and geographic differences have emerged, leading not only to policy adjustments, but also changes to the understanding of regionalisation and regional policy, and the actors involved.  相似文献

This article examines the relationship between the human right to water and indigenous water rights as articulated in the legal strategies of indigenous Yaqui (Yoemem) leadership in Mexico, and in the jurisprudence of the Inter-American Human Rights System. Accelerated urban growth and climate change in the area of study are rekindling historical water conflicts between rural indigenous communities and state authorities encouraging urban development. This configuration is not unique to Northwestern Mexico and, thus, offers an instructive case for exploring contradictions and alignments between indigenous right claims and the human right to water. This article addresses the following questions: What role does the human right to water play in the competing claims of state authorities and indigenous Yaqui leadership in Mexico? To what extent can the human right to water be reconciled with the collective rights of indigenous peoples? And in particular, what can be learned from international jurisprudence in this regard? Through content analysis of legal documents and media sources I show that even when Yaqui claims over water are advanced in the arena of international human rights, the human right to water does not have a primary role in framing their demands. In fact, I show that the human right to water was primarily mobilized to uphold rural-to-urban water transfers and undermine indigenous opposition to large-scale infrastructure development. This article produces new empirical knowledge to contribute to scholarship examining what a human right to water means in practice. This line of research is particularly timely as the human right to water becomes institutionalized in the context of growing public debate and legal discussions on collective indigenous rights.  相似文献

In northeast Mexico is Linares City, which has an extensive agricultural area and many industrial activities. Near this city is the Cerro-Prieto Dam (~12 km NE direction); this drinking water reservoir captures the water of the Pablillo River catchment area and constitutes an important source of potable water for the metropolitan area of Monterrey, the largest urban center of this region. Groundwater sources in this area provide drinking water to Linares inhabitants. A hydrogeological and hydrochemical study was conducted on the shallow aquifers surrounding the urban centers (Linares and Hualahuises) to determine the evolution of the water quality between 1981 and 2009. The hydrochemistry was assessed upgradient and downgradient from the potential contamination sources in Linares city. Groundwater showed a chemical evolution from calcium-bicarbonate type to calcium–sodium-sulfate type. The water qualities in the downstream area after Linares are inferior compared to the upstream area before the city. Nitrate concentrations in groundwater increased significantly after 28 years indicating an important pollutant process in this period of time over the study area. The possible pollution sources could be the agricultural and farm activities, industrial development, landfills leachate, septic tanks and wastewater of municipal and domestic consumption. If the present scenario continues, an aquifer vulnerability assessment would be important for the sustainable water management.  相似文献

Informal settlements become an intriguing spatial dimension of urbanization in those countries which experience the systemic shift from socialism to neoliberal regimes. This paper takes chengzhongcun(s) (literally meaning ‘villages encircled by the city’ boundaries) as a case to explore the dynamics of informal settlements in post-socialist China that has certain distinctive features related to the legacy of socialist institutions and restructuring of urban space by various forces. The paper details the political and economic contexts, as well as the ways in which chengzhongcun(s) are transformed into functional but unregulated urban space. It also elucidates the policy approach towards formalizing chengzhongcun(s) and confrontation involving in government-led redevelopment. The analysis illustrates how spatial informality is shaped by the interaction of economic interests and political considerations in a post-socialist economy with retaining the rural-urban dualism of land ownership and the control of urban citizenship.  相似文献

With over 40% of the water supply of Western and Eastern Europe coming from urban aquifers, efficient and cost-effective management tools for this resource are essential to maintain the quality of life. However, the increasing concerns about the environmental impacts of water projects and their increasing economic costs mean that traditional planning concepts, which assume unlimited supplies of potable water, must be questioned. This includes the source of the water supply and its appropriate use. Urban transport systems and the provision of water have been identified as the most critical factors that determine the future of cities in this century. The objective of an interdisciplinary research project presented in this paper is to identify and develop systems and technologies and integrative processes and analytical tools, which are commercially valuable, scientifically robust and which improve the cost effectiveness of urban water services, in line with the programs vision of ecological sustainability. As part of this program, a software tool has been developed to estimate the water flows and contaminant loads within the urban water system. This paper presents first modelling results of water and contaminant flows through the existing urban water, wastewater and stormwater systems, from source to discharge point.  相似文献

This paper examines, first, the conditions under which irrigating farmers are being alienated from their water through a state-led process of dispossession, and then, second, details the dialectical process of farmers’ resistance to these efforts. The paper advances recent scholarship on water grabbing and ‘accumulation by dispossession’ by drawing on a case from northwestern India to explore the connections between non-agrarian economic growth, irrigated agriculture and farmer livelihoods. Specifically, it examines an urban water infrastructure development project that aims to provide water to Jaipur, the Indian state of Rajasthan’s capital city, through the appropriation of an existing rural dam/reservoir complex built for irrigation and redirecting it to domestic, commercial and industrial uses. Drawing on an examination of policy documents and interviews with farmers and state planners, this paper argues that these transfers must be understood as a supply-side solution to support economic growth, where the lack of stable water supplies is a barrier to capital accumulation. The paper contributes to critical scholarship by showing that the processes underpinning water’s reallocation are specific acts of ongoing ‘dispossession’ through extra-economic means under advanced neoliberal capitalism, which alienates water away from peasant producers towards new centers of capital accumulation, dialectically creating peasant resistance to these efforts.  相似文献

This paper critically explores the politics that mediate the use of environmental science assessments as the basis of resource management policy. Drawing on recent literature in the political ecology tradition that has emphasised the politicised nature of the production and use of scientific knowledge in environmental management, the paper analyses a hydrological assessment in a small river basin in Chile, undertaken in response to concerns over the possible overexploitation of groundwater resources. The case study illustrates the limitations of an approach based predominantly on hydrogeological modelling to ascertain the effects of increased groundwater abstraction. In particular, it identifies the subjective ways in which the assessment was interpreted and used by the state water resources agency to underpin water allocation decisions in accordance with its own interests, and the role that a desocialised assessment played in reproducing unequal patterns of resource use and configuring uneven waterscapes. Nevertheless, as Chile’s ‘neoliberal’ political-economic framework privileges the role of science and technocracy, producing other forms of environmental knowledge to complement environmental science is likely to be contentious. In conclusion, the paper considers the potential of mobilising the concept of the hydrosocial cycle to further critically engage with environmental science.  相似文献

In recent years, economic geographers have drawn extensively upon notions of ‘cultural embeddedness’ to explore how spatially variable sets of cultural conventions, norms, values and beliefs shape firms’ innovative performance in dynamic regional economies. However, our understanding of these causal links remains partial, reinforced by an ‘over-territorialised’ conception of cultural embeddedness which sidelines the role of institutional actors operating outside and across the boundaries of ‘the local’. So motivated, this paper offers a theoretically-informed - and theoretically informing - empirical analysis of the high tech regional economy in Salt Lake City, Utah to explore the everyday causal mechanisms, practices and processes - both local and extra-local - through which firms’ cultural embedding within the region is manifested, performed and (un)intentionally (re)produced. In so doing, this paper aims to further our understanding of the constitutive entanglement and complex interweaving of cultural/economic practices, and to contribute to the development of an in-depth empirical corpus of work which compliments the exciting conceptual developments that have largely dominated cultural economic geography over the last decade.  相似文献

Understanding ecosystem processes from a functional point of view is essential to study relationships among climate variability, biogeochemical cycles, and surface-atmosphere interactions. Increasingly during the last decades, the eddy covariance (EC) method has been applied in terrestrial, marine and urban ecosystems to quantify fluxes of greenhouse gases (e.g., CO2, H2O) and energy (e.g., sensible and latent heat). Networks of EC systems have been established in different regions and have provided scientific information that has been used for designing environmental and adaptation policies. In this context, this article outlines the conceptual and technical framework for the establishment of an EC regional network (i.e., MexFlux) to measure the surface-atmosphere exchange of heat and greenhouse gases in Mexico. The goal of the network is to improve our understanding of how climate variability and environmental change influence the dynamics of Mexican ecosystems. First, we discuss the relevance of CO2 and water vapor exchange between terrestrial ecosystems and the atmosphere. Second, we briefly describe the EC basis and present examples of measurements in terrestrial and urban ecosystems of Mexico. Finally, we describe the conceptual and operational goals at short-, medium-, and long-term scales for continuity of the MexFlux network.  相似文献

Research pertaining to children’s geographies has mainly focused on children’s physical experiences of space, with their ‘imagined geographies’ receiving far less attention. The few studies of children’s imagined geographies that exist tend to focus on children’s national identities and their understanding of distant places. However, children’s lives are not necessarily static and they often move between places. Research has not so far considered children’s images of these transitional spaces or how such images are constructed.Through an examination of over 800 thematic drawings and stories, regarding ‘moving house’, produced by children aged 10-17 years in urban and rural communities of Lesotho and Malawi, this paper explores southern African children’s representations of migration. The research considers how ideas of migration are culturally-constructed based on notions of family, home and kinship, particularly in relation to the fluid family structure characteristic of most southern African societies. The results suggest that most children imagine migration as a household rather than an individual process, rarely including micro-migrations between extended family households in their drawings. Further, children’s images of migration are place-rooted in everyday life experiences. Their representations concentrate on the reasons for migration, both negative and positive, which are specifically related to their local social and environmental situations and whether house moves take place locally or over longer distances. The paper concludes by exploring the implications of these conceptualisations of moving house for children’s contemporary migration experiences, particularly in light of changing family structures due to the effects of the HIV/AIDS pandemic.  相似文献

Notwithstanding the burgeoning scholarship on enclave urbanism, urban gating has often been pigeonholed as an intra-urban development that is somewhat ‘epiphenomenal’ to wider global processes. Overlooked in the literature is how gated communities as globally-oriented spaces are intertwined with the transnational lifeworlds of its elite inhabitants. As key sites where transnational super-rich elites organize their consumption and reproduce their purportedly global lifestyle, gated communities are now emerging as a new ‘meta-geographical form’ that circulates in and around rapidly globalizing cities. Drawing on the case study of Sentosa Cove, an exclusive waterfront gated community in Singapore catering to ‘high net-worth’ residents, this paper critically examines how elite localities and transnationalism are being socially and spatially reproduced in the city-state. To this end, the paper makes a distinct contribution by bringing to bear critical transnationalism perspectives in the understanding of urban gating and the privileged geographies of the global super-rich.  相似文献

Guanajuato State, located in central Mexico, with less than 2% of the countrys area, has almost 17,000 deep water wells, from which nearly 4,000 cubic hectometers (hm3) per year are being extracted, more than 1,000 hm3 over the estimated renewable yield. Since, in Mexico, water is administered under federal jurisdiction by the National Water Commission (CNA, for its Spanish acronym), the state government faces the challenge of ensuring its populations economic development without formal means of intervention. Being thus limited to apply mandatory policies and measures, the state water program has focused on the implementation of a two-sided strategy. First, basic hydrogeological studies and mathematical groundwater hydrodynamic models were developed upon a comprehensive survey of existing wells and a general revision of the states geological framework. Second, a structure for water users participation in water management actions was promoted (from the dissemination of information to the implementation of pilot efficient water use projects) with financial, technical and political support from the state. Simultaneously, a coordinated effort towards the completion of the water users registry was performed with the federal authority along with other supporting measures such as training and monitoring programs. In this paper, a general overview of the projects achievements and challenges is presented.To make direct contact with the water-user associations mentioned in this paper, please write to Eng.

This paper deals with the changes brought about by the ‘reforms’ in water currently under way in many parts of the world. Three particular reforms in the state of Maharashtra in western India are discussed - the commercialization of a parastatal body, the concept of self-sufficiency as it plays out in the context of urban local bodies, and the working of the regulatory body in water. The analysis of these reforms shows how, in common with neoliberal projects elsewhere, changes in institutional practices are resulting in changes in subjectivities, foreclosing alternatives, and leading to attempts to ‘depoliticize’ the water arena. At the same time, there are differences between the regulatory experience of Maharashtra and regulation in other locales, which offers insights into how neoliberalism works in a context where water reforms have emerged relatively late.  相似文献

Groundwater is crucial for multiple uses over the world, especially in arid and semiarid regions. However, human activities significantly decreased groundwater quality. In this study, the spatiotemporal variation of groundwater quality was evaluated in an arid area where long-term paper wastewater irrigation has been implemented. For this study, seven wells were regularly monitored for physicochemical parameters over a period of 1 year. Statistical and graphical approaches were applied to interpret the spatiotemporal variation of groundwater quality parameters in the wastewater irrigation zone. Correlation analysis was also carried out to reveal the sources of some major ions. The results indicate that the groundwater type in the study area is dominated by the Cl–Na, followed by the HCO3–Na, the HCO3–Ca·Mg, and the SO4·Cl–Ca·Mg types. Groundwater in the area is significantly contaminated locally with fluoride, nitrite and ammonia, and the chemical oxygen demand levels were increased in some groundwater monitoring wells. Most contaminants showed an increasing trend from the Yellow River water irrigation zone toward the wastewater irrigation zone. Rock weathering, mineral dissolution, and cation exchange are important processes controlling groundwater quality, but human activities, such as wastewater irrigation, play an undeniable role in affecting groundwater quality in this area. The results of this study contribute to the understanding of the formation and circulation of groundwater under human activities and provide a scientific basis for regional water quality evaluation, water quality improvement, and protection.  相似文献

This paper explores young people’s experiences and perceptions of mobility and mobility constraints in poorer urban areas of Ghana, Malawi and South Africa within the specific context of inter-generational relations. Drawing principally on qualitative research findings from a study involving both adult and child researchers, our aim is to chart the diversities and commonalities of urban young people’s mobility experiences in the everyday - how they use and experience the city - developing a comparative perspective across three urban study sites which links young people’s mobility with the power relations that operate to shape their movements in individual locations. In particular, we consider how positive and negative images of young people’s mobility play out in terms of the inter-generational frictions and negotiations generated by their mobility performances. We also reflect on the developmental implications, in terms of young people’s access to services and income and their participation in the social networks and peer culture which may shape their life trajectories. Three themes are explored in detail: mobility as challenge, mobility as temptation and mobility control.  相似文献

Study on hydraulic geometry can reveal the response of river systems to basin attributes, and the trends in channel change. Based on 35 years of data collected at 10 hydrological stations (cross-sections), the hydraulic geometry relations between cross-sectional variables and discharge were established, and the derived parameters were analyzed. The channel behavior of the mountainous bedrock reach (from riverhead to Xunhua cross-section) and the alluvial reach (from Xunhua to Toudaoguai cross-sections) differed significantly over the past decades in response to dramatic water and sediment changes. The hydraulic geometry quasi-equilibrium was achieved through equally adjusting water depth and flow velocity in the mountainous bedrock reach; while primarily through flow velocity in the alluvial reach. The change rate of river width with varying discharge was relatively small in the whole upper Yellow River. Compared with the lower Yellow River and other rivers in the world, both similarity and differences existed, indicating the general adjustment direction of hydraulic quasi-equilibrium and also the importance of considering other influencing factors in hydraulic geometry studies. In addition, dams played an important role in affecting the changes of hydraulic geometry exponents.  相似文献

The aquifer system of the Basin of Mexico is the main source of water supply to the Mexico City Metropolitan Zone. Management of the Basin’s water resources requires improved understanding of regional groundwater flow patterns, for which large amounts of data are required. The current study analyses the regional dynamics of the potentiometric groundwater level using a new database called the Basin of Mexico Hydrogeological Database (BMHDB). To foster the development of a regional view of the aquifer system, data on climatological, borehole and runoff variables are part of the BMHDB. The structure and development of the BMHDB are briefly explained and then the database is used to analyze the consequences of groundwater extraction on the aquifer’s confinement conditions using lithology data. The regional analysis shows that the largest drawdown rates are located north of Mexico City, in Ecatepec (a region that has not yet received attention in hydrogeological studies), due to wells that were drilled as a temporary solution to Mexico City’s water-supply problem. It is evident that the aquifer has changed from a confined to an unconfined condition in some areas, a factor that is responsible for the large subsidence rates (40 cm/year) in some regions.  相似文献

Baldacchino [Baldacchino, G., 2002. Jurisdictional self-reliance for small island territories: considering the partition of Cyprus, The Round Table, 365, 349-360] has argued that the ‘troika’ of smallness, insularity and peripherality may incline island peoples (rather more than mainlanders?) to question the effects of economic globalization and be especially disposed to innovative approaches to development. He views jurisdictional capacity as integral to that task. Much of the literature on such issues relates to island nations, but this work focuses on Australia’s smallest and only island state of Tasmania, and thus on a sub-national jurisdiction. In what follows I explore the effects of an attempt to enrol Tasmanians in the creation and stabilization of a ‘2020 vision’ meant to be global in its reach, to focus on the particular strengths of the island state, and be innovative in advancing sustainable development. Known as Tasmania Together, the 20-year strategic vision outlines diverse economic, social and environmental goals assembled over two years via widespread consultations with the island’s communities of place and interest. For a time Tasmania Together generated significant debate about what it means to be an island people, and whether and to what extent Tasmanians’ future will be secured through economic globalization or localized endeavours premised on sustainability principles. Important to Tasmanians as well as to island studies, these rhetorics of social and spatial engagement also have salience beyond the borders of the island state, highlighting larger questions about the technologies of governmentality, agency and the performance of identity.  相似文献
