Drawing together insights from neo‐Innisian geography and environmental history, this paper explores the landscape and environmental changes engendered by ‘cyclonic’ patterns of development associated with uranium production at Uranium City, Saskatchewan. Strong postwar demand for uranium led to the establishment and rapid expansion of Uranium City on the north shore of Lake Athabasca as a ‘yellowcake town’, dedicated to producing uranium oxide concentrate to supply federal government contracts with the US military. In spite of optimistic assessments for the region's industrial future, the new settlement remained inherently unstable, tied to shifting institutional arrangements and external markets, and haunted by the spectre of resource depletion. The planning and development of the townsite at Uranium City reflected both neocolonial desires to open the north to Euro‐Canadian settlement and efforts by the state to buffer the stormy effects of resource dependency. Ultimately, however, quixotic government efforts to implant an outpost of industrial modernity in the Athabasca Region failed to forestall the inevitable winds of change, which left in their wake destructive legacies of social dislocation and environmental degradation, already evident with the near‐collapse of the uranium export market by the early 1960s.  相似文献

In efforts to become “smart cities,” local governments are adopting various technologies that promise opportunities for increasing participation by expanding access to public comment and deliberation. Scholars and practitioners encounter the problem, however, of defining publics—demarcating who might participate through technology-enhanced public engagement. We explore two case studies in the city of Calgary that employ technologies to enhance public engagement. We analyzed the cases considering both the definition of publics and the level of citizen participation in areas of participatory budgeting and secondary suites. Our findings suggest that engaging the public is not a straightforward process, and that technology-enhanced public engagement can often reduce participation towards tokenism. City councillors and planners need to critically confront claims that smart cities necessarily enhance participation. Moving beyond tokenism requires understanding “public” as a plural category. Municipal governments should seek to proactively engage citizens and communities utilizing helpful resources including, but not limited to, digital tools and smart technologies. This would allow planners to keep a “finger on the pulse” of publics' concerns, better identifying and addressing issues of equity and social justice. It is also important to consider how marginalized publics can best be recognized in order to bring their concerns to the fore in decision-making processes.  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

This paper develops a critique of Western representations of discovery, centrality and self-identity via a focus on Portugal's Expo '98. Two of the towers of the title were incorporated into the site of Expo '98 (the last universal exposition of the twentieth century), which offered the chance to reiterate the importance of Portugal's imperial discoveries on a global stage and to reaffirm Portuguese national identity in the process. The paper examines how historical and geographical narratives of imperialism and the ‘Portuguese voyages of discovery’ were reworked in Expo '98 to resurrect a national sense of pride in belonging to and pioneering Europe. Critical postcolonial perspectives which break with Eurocentrism are required if the role of other cultures and histories in the Portuguese contribution to the making of modernity is to be appreciated. Such perspectives enable wider reflections about the constitution of the West and the non-West in the making of a multifaceted modernity of which expositions (and monumental towers) are concentrated expressions.

Portugal's was the pioneer empire in more ways than one, and it exhibited all the defects as well as all the glories of the age it inaugurated. No Nation of the fifteenth or sixteenth century ever saw more, reported a greater variety of things, or left more of its imprint on the modern world, whose chief characteristic, after all, is mobility.

The article is a critical review of the literature investigating the impact suburbanization has had since the mid-20th century on the downtowns of Canadian mid-size cities and the strategies deployed to revitalize these districts. It demonstrates that large city downtowns are more likely than their mid-size city counterparts to enjoy conditions favourable to their success, hence the need to devise revitalization efforts tailored to the reality of mid-size city downtowns. The article identifies revitalization strategies adopted over the last decades, which mostly failed to reverse the decline affecting these downtowns. It then concentrates on the present, and likely enduring, revitalization model, which emphasizes hospitality, recreation, culture, services, and walkability. The article refines the understanding of the differences between mid-size and large city downtowns by concentrating on their specific dynamics and explores future revitalization options for mid-size city downtowns. It discusses the present and likely enduring absence of alternatives to the present revitalization model and highlights its equity downsides as it challenges the downtown low-income resident living environment.  相似文献

This article investigates the housing experiences of international students in comparison to other newcomers in the mid-sized Canadian city of St. John's, Newfoundland and Labrador, with a focus on how they navigate housing crises. Drawing on recent literature on housing justice, a quantitative survey of 188 participants, and 30 qualitative interviews, the findings reveal that international students and other newcomers are at different stages of their housing careers, have different needs and goals, and are experiencing the affordability crisis differently. Housing discrimination is a pressing concern, especially for international students who are subjected to intersectional prejudice, exploitation by landlords, and amplified challenges due to the COVID-19 pandemic. The article argues for inclusive housing and immigration policies that acknowledge international students as part of the Canadian housing market and ensure their rights to housing.  相似文献

Alternative food systems (AFS), which are known for their reduced food supply chain and have positive benefits for health, the environment, and local communities, offer an alternative to the conventional (industrialized) system of quality food. However, several studies question the accessibility to these food systems, especially when food insecurity remains a significant issue for many communities in North America. This article examines the accessibility of AFS among lower-income populations by taking into account the urban context, including the food environment and proximity to production areas. Using the case of a borough of Montreal and the medium-sized city of Victoriaville (Quebec), we carried out a mixed methodology combining mapping and observation of the food environment and semi-structured interviews. We show that the price of AFS (economic dimension of its access) is moderated by factors specific to each territory such as temporality, relationships to food and agriculture, and proximity to producers. The Montreal borough and the medium-sized city also stand out for their way of (re)connecting to agricultural producers. These results could help optimize public policies that focus on access to quality food and thus make AFS more accessible.  相似文献
