Although the “food desert” concept has captured the public imagination and spurred public policy efforts in many North American cities, the term has been critiqued by academics for being definitionally and methodologically vague, and for providing an incomplete picture of the complexity of food access. Rather than dismiss the study of urban, inner‐city food deserts, however, scholars can study disparities in retail food access through a historical, critical political economy lens to understand underserved retail landscapes as a product of capital formation and rescaling over time. The purpose of this article is to conduct such an analysis, using the case study of a low‐income community in Kingston, Ontario. Using historical research and qualitative interviews, the major finding of this analysis is that the physical accessibility of retail food appears to have declined over time in relation to the capitalization of the retail food sector. An imperfect relationship can be outlined over three phases of Canadian urban economic history to suggest that the food desert problem emerged largely in the transition from a decentralized, small‐scale, and neighbourhood‐embedded retail food industry to the scaled‐up, disembedded industry that now dominates the landscape. This industry‐level rescaling is contributing to a new urban politics of class and consumption through subtle, everyday activities such as food shopping.  相似文献

How is inner city space represented and by whom? Drawing from an extensive framing analysis of print media portrayals of Vancouver's Downtown Eastside between 1996 and 2008, we offer a detailed assessment of the predominately negative portrayal of the neighbourhood, and the centrality of three frames: medicalization, criminalization, and socialization. Certain social actors are given a privileged position in the media in the representation of the inner city. Outsiders are privileged over insiders, with the neighbourhood constituted as a problematic space and its residents as passive victims. The effect is to further the stigmatization of an already marginalized neighbourhood, and to accentuate the disempowerment of its residents.  相似文献

In this paper, we map the international trade in electronic waste (e‐waste). We quantify the directions and magnitude of this trade at the global scale and examine the utility of the pollution haven hypothesis for explaining the observed trade patterns. Our results demonstrate four key findings: the international trade in e‐waste is a more complex story than being one about ‘rich’ countries dumping waste in ‘poor’ countries; the trade in e‐waste is highly regionalized, with intra‐regional trade accounting for most of the total trade flows; the pollution haven hypothesis is an important, but partial, explanation of observed trade patterns; and there is a need to conceptualize the trade and traffic of e‐waste as open ended and contingent processes facilitated by situated practices of wasting and valuing that rely on geographic difference and mobility for the exchanges between the domains of waste and value to occur.  相似文献

Environmental decision support systems (EDSS) are designed to assist natural resource managers and stakeholders to assess problems and select options for change. EDSS that combine community engagement in developing future scenarios with computer‐based land use planning and modelling tools are widely used internationally. However, these EDSS are often not used after the research and development phase. To best understand why the EDSS are not being used in the long term, the end users of the EDSS should be consulted—a perspective that is lacking in the literature. The research reported here presents the perspectives of stakeholders involved in a community climate change adaptation project in western Canada. Evidence from the community suggests that this project was successful in instigating change. However, the EDSS was not used after the project's end. Our findings indicate that, from the end users’ perspective, the project could have had much greater and sustained success had there been ongoing engagement and communication with them, particularly in the form of continued support for the use of EDSS after the development project.  相似文献

Cet article a pour but de contribuer à la littérature en émergence portant sur la santé des Autochtones en milieu urbain, en comparant l’état de santé et les déterminants de la santé de la population autochtone et non‐autochtone en milieu urbain au Canada. L’étude s’appuie sur des données tirées de l’Enquête auprès des peuples autochtones (EPA) de 2001 et de l’Enquête sur la santé dans les communautés canadiennes (ESCC), cycle 1.1. Préconisant une approche axée sur la santé de la population, nous explorons les différences de l’état de santé et des déterminants de la santé entre les populations autochtones et non‐autochtones en milieu urbain. Trois variables sont utilisées pour décrire l’état de santé : l’auto‐évaluation de l’état de santé, les maladies chroniques et la limitation d’activités. Si l’existence de disparités en matière de santé entre la population autochtone et non‐autochtone en milieu urbain est démontrée, celles‐ci ne sont pas aussi importantes que les disparités qui caractérisent la population non‐autochtone et autochtone vivant dans une réserve. Les déterminants sociaux de la santé sont comparables pour les deux populations, mais les résultats illustrent à quel point des facteurs culturels peuvent également intervenir en faveur ou au détriment de la santé parmi la population autochtone en milieu urbain. Cette étude exploratoire fait ressortir la nécessité de tenir compte des facteurs culturels propres aux déterminants de la santé dans les recherches ultérieures afin d’identifier des pistes d’explication des disparités en matière de santé entre les individus autochtones et non‐autochtones en milieu urbain.  相似文献

This paper examines the response by local government and stakeholders to the arrival and resettlement of Syrian newcomers in Hamilton, Ontario in 2015 and 2016—the first major wave of refugee arrivals since two significant changes in Hamilton's settlement organizational landscape. The creation of a local immigration partnership called the Hamilton Immigration Partnership Council (HIPC) is an example of place‐based policymaking within local immigration and settlement in Canada. Place‐based approaches emerged to bypass top‐down policy ineffectiveness, and the shift to empower civic participation in the local decision‐making process is seen as one solution to public policy innovations. Examination of HIPC's role in this context is thus critical to understand the challenges and learnings encountered in one place‐based setting. Our findings suggest that the lack of power (in terms of information, communication, resources, and funding) led to a missed opportunity for HIPC to lead a significant resettlement initiative. HIPC's inability to bring together key partners across the sector prior to and during the event is symptomatic of systemic barriers the Council had faced, including competing interpretations of HIPC and its role by its members. This study suggests the effectiveness of place‐based policy is not without its nuances, and iterative challenges and learnings.  相似文献

Since 2009, Innu members of the community of Ekuanitshit have faced a major hydroelectric project on the Romaine River, an integral part of the Nitassinan, their ancestral territory. In this paper, we study the project's impacts on the material and ideational relationship the Innu have with the river. We explore the idea that the project transforms the traditional relationship to territory into a more pragmatic one, marked by economic and political interests. Our analysis reveals that the Innu's territorialities, though partly transformed by increased contact—and sometimes conflict—with hegemonic non‐indigenous society, remain anchored in a strong cultural heritage and a deep identification with territory. We argue that these seemingly differentiated conceptualizations, of traditions on the one hand and development on the other, are not incompatible. These conceptualizations comprise dynamic cultural, social, and political territorialities which are thus internal and external, ancestral and contemporary.  相似文献

It has recently been suggested that cities and regions should focus upon attracting talented individuals as a means to develop. Such a suggestion implies two things: first that it is possible to meaningfully alter migration flows by way of local policy, and second that these flows have an effect on local growth (and not the reverse as has generally been admitted). In this paper, we begin to investigate the empirical foundations of such assertions by examining some structural determinants of graduate migration flows by comparing them, in a gravity model context, to flows of nongraduates. Our contention is that, if migration flows are structured by such factors, then policies aimed at modifying flows—and any research purporting to give such policy advice—must first take them into account. We show that migration flows are strongly dependent on basic gravity variables such as size and distance, but that these and other variables (such as income differences, presence of graduates and border effects) do not affect all flows equally. Furthermore, we show that certain factors that are assumed to be local (such as wage levels) in fact only operate at a provincial level. Thus policies implemented locally may have little or no effect if they are manipulating factors that operate at a different scale.  相似文献

A cased and sealed borehole in the Northern Barbados accretionary complex was the site of the first attempts to measure permeability in situ along a plate boundary décollement. Three separate efforts at Hole 949C yielded permeability estimates for the décollement spanning four orders of magnitude. An analysis of problems encountered during installation of the casing and seals provides insights into how the borehole conditions may have led to the wide range of results. During the installation, sediments from the surrounding formation repeatedly intruded into the borehole and casing. Stress analysis shows that the weak sediments were deforming plastically and the radial and tangential stresses around the borehole were significantly lower than lithostatic. This perturbed stress state may explain why the test pressure records showed indications of hydrofracture at pressures below lithostatic, and permeabilities rose rapidly as the estimated effective stress dropped below 0.8 MPa. Even after the borehole was sealed, the plastic deformation of the formation and relatively large gap of the wire wrapped screen allowed sediment to flow into the casing. Force equilibrium calculations predict sediment would have filled the borehole to 10 cm above the top of the screen by the time slug tests were conducted 1.5 years after the borehole was sealed. Reanalysis of the slug test results with these conditions yields several orders of magnitude higher permeability estimates than the original analysis which assumed an open casing. Overall the results based on only the tests with no sign of hydrofracture yield a permeability range of 10?14–10?15 m2 and a rate of increase in permeability with decreasing effective stress consistent with laboratory tests on samples from the décollement zone.  相似文献

Freeze‐thaw cycles are most common at the beginning or near the end of the winter season. These cycles have various effects on the ecosystems of Eastern Canada, affecting both biotic and abiotic components of temperate cold environments. Using air temperature minima and maxima from four meteorological stations close to Québec City, we determined the frequency of daily freeze‐thaw cycles for the last 30 years. The results show no significant increase in the number of freeze‐thaw cycles despite a small increase in air temperature. Polynomial curves describing the relationship between mean air temperatures and the number of freeze‐thaw cycles were calculated. Based on these equations and anticipating a climate change scenario, we projected future freeze‐thaw cycles. Assuming a 5 °C increase in mean air temperatures by 2100, we estimated that the number of days with a freeze‐thaw cycle could increase by approximately 20 days per winter. The increase in the number of such cycles will be concentrated during the coldest months of the winter (January and February).  相似文献

While the Saint‐Laurent river is considered to be the cradle of Québécois society, many other great rivers are found across the province—other cradles of civilizations, indigenous to the continent, notably the Chisasibi and the Manicouagan. These rivers played a key role in the Québécois movement of affirmation and modernization in the twentieth century. They are valued by many people in Quebec for their hydroelectric output rather than for their cultural richness and significance for the Eeyou (Cree) and Innu Nations. Since the 1990s, I have been able to study Quebec's historical geography from the standpoint of these rivers thanks to the expertise of Eeyou and Innu knowledge holders. Using the concept of decolonization as a practice, I explore how this has impacted both my work as a geographer and my cultural identity as a Québécois woman.  相似文献

Starting from an econometric model of local employment growth, applied to Canada (1971–2001), residuals—relative to model predictions—are analyzed over time and over space, in turn allowing us to draw a distinction between general explanatory variables and factors of a more local, cyclical or accidental nature. The model's explanatory power grows over time, founded on variables such as urban size, market access and industrial structure, allowing us to conclude that local employment growth in Canada follows an increasingly geographically predictable pattern. However, an examination of the residuals reveals more localized processes. Growth volatility is most manifest in Alberta and British Columbia, home to the most erratic local economies. Emerging patterns are visible in the last period, most notably the underperformance of Northern Ontario and of non‐metropolitan communities between Windsor and Québec City, lying along the Great Lakes and the Saint Lawrence. The over‐performance—compared to model predictions — of small and mid‐sized towns in south‐eastern Québec can, on the other hand, be interpreted as a sign of truly local social processes, generally associated with a particularly dynamic local entrepreneurial class.  相似文献
