An illustrated methodology for the morphodynamic sectoring of the Neigette River (Québec) Fluvial hydrogeomorphology is little recognized in policy management and planning in Québec. A better understanding would result in more enlightened planning for waterways. The deficiency could result from the fact that too few methodologies have been developed that take account of the particular nature of Québec rivers. This study tests the applicability of a methodology of dividing rivers into homogeneous morphodynamic units. This compartmentalization results from the analysis of longitudinal changes in stream power, sedimentary composition of the banks, channel entrenchment, and planform geometry. The method is tested on a section of the Neigette River, which encompasses a wide variety of forms and processes frequently found in Québec rivers. Results suggest the presence of three morphodynamic sections: wandering with multiple channels, dynamic meandering and stable meandering. The method provides an effective basis for discriminating between these morphodynamic environments and their respective limits. Stream power is the variable with the greatest discriminating capacity. The efficacy of the approach, the ease of its application, and its flexibility make this a valuable tool for the management of fluvial environments.  相似文献

The African continent is known by various metaphors and geographies, but for many there are also unknowns about the continent. Geopolitically, Africa is a continent that is considered remote—an economically emerging continent seen as entangled in persistent challenges of wars, political dictatorship, poverty, disease, and more recently migration. Given these predispositions it is typical to stereotype events, practice, and behaviour as “African.” There is, however, now recognition of the continent as emerging economic power house. But unpacking the diversity of Africa reveals a huge potential with respect to resource endowments, diversity of ecology, socio‐cultural economic advancement, politics, language, and demographics. Colonial history coupled with traditional Africa shaped the geopolitical boundaries that have added to the confusion about this massive and diverse continent. Intellectual discourses either amplify the differences due to specificities of geographical focus or generalizations such as the contested notion of “African.” However, using socio‐ecological lenses, Africa is unified by these very differences in addition to being a massive landmass with several big and small island states. Appreciating these differences is useful to understanding the observed patterns of social, economic, and political systems that unify the continent. This paper illustrates the notion of “African” to describe the heterogeneous nature of a “unified” continent. Some illustrative examples between Africa and other continents are used.  相似文献

One of the significant developments in the interdisciplinary field of judgment and decision making is the classification of environments as a function of (a) their capacity to enable people to learn from experience (kind environments vs. wicked environments) and (b) the consequences of having failed to understand and adapt to them (exacting environments vs. lenient environments). Based on the premise that ‘environment’ is a key geographical concept, I explore the usefulness of appropriating these classifications in geography and argue that they can stimulate normative work on the possible contours of a better world as well as illuminate in novel ways long‐standing geographical concerns with the problematic of fairness.  相似文献

There are three interconnected and fundamental elements that define the spatiality of crime: places, distances, and directions. Over the past 180 years, research has flourished for the first two fundamental elements with relatively little research on directionality. In this article, we develop a visualization technique allowing for the display of the directional bias for a large number of offenders that aids in subsequent analysis. We show that a directional bias in criminal activity is present overall, but is not monolithic. Consequently, urban form and understanding place play a strong role in criminal directional biases for moving through our environments.  相似文献

Scientists advise limiting global warming to 1.5°C with substantial actions by 2030. Our viewpoint argues that climate response strategies in Canada have underemphasized and underestimated the potential contribution deep energy retrofits can make to greenhouse gas (GHG) emissions reductions, leading to inadequate responses in the building sector, and that Canada can (and should) be ambitious with building retrofits over the next decade. GHG savings from building retrofits can be realized more quickly than GHG reductions from other sectors, and either deliver net cost savings or are cost‐effective when compared to other mitigation measures. Retrofits can also provide social and economic benefits, such as improved health and comfort, and lower energy costs. This paper reviews energy use and building retrofits in Canada and argues the following should be implemented: (1) focus innovation on deep energy retrofit processes, not singular retrofit actions; (2) maximize both social and environmental benefits; (3) improve data gathering and availability for analysis and delivery; (4) innovate for a process of decisions and to avoid “dropouts” during the retrofit process; and (5) focus innovation on business models that maximize benefits.  相似文献

Like many other forms of scholarship in geography, tourism geography has evolved as a distinct subfield of inquiry within the discipline, although the contributions of tourism geographers are perhaps more readily acknowledged in the multidisciplinary realm of tourism studies. I trace the evolving relationship of tourism geography to both the discipline of geography and to the field of tourism studies. In doing so, I reflect on such influences as the role of institutions, paradigm shifts, technology, and other factors that affect the creation and management of geographic knowledge in the twenty‐first century. The intent of this article is two‐fold: first, to appeal to geographers for greater recognition of the importance of tourism as a quintessential component of geographic study that in today's world warrants integration into core aspects of geographic enquiry; second, to use current debates within both tourism studies and geography to reflect on issues of disciplinarity, interdisciplinarity, transdisciplinarity, and even postdisciplinarity.  相似文献

Recent studies on urban poverty in Canadian cities suggest a growing spatial concentration of poor populations within metropolitan regions. This article assesses trends in the intra‐urban distribution of the poor population from 1986 to 2006 in eight of Canada's largest cities. We consider five well‐known dimensions of segregation, as identified by Massey and Denton (1988) , in order to examine changes in the spatial distribution of poor populations within metropolitan areas: evenness, exposure, concentration, clustering, and centralization. These indices were calculated for low‐income populations at the census tract level using data from five Canadian censuses. Although each metropolitan area has distinctive characteristics, we were able to identify some general trends. The results suggest that, in 2006 compared to 1986, low‐income populations lived in more spatially concentrated areas, which were, at the same time, socioeconomically more homogeneous and more dispersed throughout the metropolitan area. In addition, we observed that over the last twenty years areas of poverty have been located, for the most part, in neighbourhoods adjacent to downtown cores. Nevertheless, we found that poverty has mostly increased in suburban areas located outside inner‐city neighbourhoods. Growing socioeconomic homogeneity and dispersion of low income areas in metropolitan areas reveal new spatial patterns of urban poverty distribution. These findings should be cause for concern as social isolation in the most disadvantaged neighbourhoods could affect the life chances and opportunities for the residents of those areas.  相似文献

Paleoenvironmental science has experienced a recent surge in interest and activity as concerns grow over global environmental change. Key research questions in the biotic realm of paleoenvironmental science focus on explaining climatic change at time scales of decades to centuries and understanding ecosystem responses to these changes. Biotic responses are increasingly being studied at smaller spatial scales to identify local factors that determine the sensitivity of a particular system to climatic change. These findings can then be applied to solving a variety of problems, such as setting conservation targets or testing mechanisms for observed climatic and biogeographic phenomena. Research approaches commonly used today include hypothesis testing, which has now become more sophisticated as paleoecologists and paleoclimatologists integrate with modellers. Other frameworks involve the quantitative integration of multiple proxy indicators and the use of extensive publicly available data networks to produce new datasets for paleoclimatic reconstructions and other applications.  相似文献

Through a study of trade fairs, this article illustrates that relational approaches to economic geography are not limited to the sphere of economic and social relationships. These relationships are influenced by and, in turn, shape material realities, such as specific infrastructure and the labour market, in a reflexive manner. Trade fairs are “relational events” that bring together regional, national, and often international producers, users, suppliers, and other agents of a value chain or technology field for the purpose of exchanging knowledge about technological and market developments, building partnerships, and maintaining existing networks through learning by interaction and observation. However, these events are also situated in space and time, grounded in the contexts of particular industries, trade patterns, public and private investments, as well as the economic geographies of places. Focusing on North America, this article presents and analyzes data on the economic geography of trade fairs and their regional economic impact (number of events, exhibitors, attendees, exhibition space). It explores regional trade fair patterns and dynamic changes in major trade fair cities by emphasizing the role of history and industry context.  相似文献

Academic geographers are working in a system in flux. A series of interconnecting and overlapping social, political, and economic processes have resulted in a shifting academic climate for geographers and geography departments. This viewpoint brings forward evidence from multiple areas of study to provide a synthesis of this changing context. Challenges to geography include the role of “facts” and “truth” in society, neoliberal university contexts as workplaces, and generational change, among many others. This paper asks more questions than it answers, with an aim to promote an engaged and informed debate among geographers about our “place” in Canada's shifting academic context.  相似文献

The coexistence of conservative and liberation perspectives within the Roman Catholic Church still causes disagreements. However, since Vatican II, the Catholic Church in Guatemala has established a commitment to act as a church of the poor. There is tension between Guatemala's elite and the Church, which has led to the murders of Church members and the issuance of death threats to others. Although the growth of evangelical movements has caused the Church to lose influence, the Church remains committed to the poor, which places it in sharp contradistinction to neoliberalism.  相似文献

The uneven distribution of environmental hazards across space and in vulnerable populations reflects underlying societal inequities. Fragmented research has led to gaps in comprehensive understanding of and action on environmental health inequities in Canada and there is a need to gain a better picture of the research landscape in order to integrate future research. This paper provides an initial assessment of the state of the environmental health research field as specifically focused on vulnerable populations in Canada. We present a meta‐narrative literature review to identify under‐integrated areas of knowledge across disciplinary fields. Through systematic searching and categorization, we assess the abstracts of a total of 308 studies focused on the past 30 years of Canadian environmental health inequity research in order to describe temporal, geographical, contextual and epistemological patterns. The results reveal that there has been significant growth in Canadian research documenting the uneven distributions and impacts of environmental hazards across locations and populations since the 1990s, but its focus has been uneven. Notably, there is a lack of research aimed at integrating evidence‐based and policy‐relevant evaluation of environmental health inequities and how they are created and sustained. Areas for future research are recommended including more interdisciplinary, multimethod and preventive approaches to resolve the environmental burden placed on vulnerable populations and to promote environmental health equity.  相似文献

Geography and the medical‐health sciences have long histories of engaging the humanities. The last decade has seen for both disciplines a significant growth in theoretical frameworks, pedagogic strategies, and research methods that draw upon visual and literary arts, critical self‐reflection, creative tools and expressions, and even direct engagement or partnership with artists, curators, authors, theatre‐practitioners, and other professionals in the arts. Both geographers and medical‐health professionals, then, are increasingly (re)making and understanding various worlds through the humanities. In this paper we explore the histories of humanities in both geography and the medical‐health sciences, especially medicine: we argue the two disciplines have much to learn from each other's engagement and work with the humanities. Focusing on the increasing use of narrative and storytelling in both disciplines, we argue that deployment of humanities‐based frameworks and impulses must not be taken up without careful and critical analytical reflection. Finally, we ground our theoretical explorations with empirical examples from recent community‐based work about the risks and benefits of storytelling and visual arts when looking at the health geographies of Indigenous and settler peoples in Northern British Columbia.

De manière impromptue : vers une démarche critique sur les méthodes de mise en récit et les méthodologies en géographie et en sciences médicales et de la santé

L'intérêt pour les sciences humaines par la géographie et les sciences médicales et de la santé s'inscrit dans une longue tradition. Au cours de la dernière décennie, les deux disciplines ont connu une importante croissance de cadres théoriques, de stratégies pédagogiques et de méthodes de recherche qui font appel aux arts visuels et à la littérature, à l'autoréflexion critique, à des outils et modes d'expression novateurs, voire même à une participation directe ou à des partenariats avec des artistes, conservateurs, auteurs, praticiens de l'art dramatique et d'autres professionnels du domaine des arts. Autant les géographes que les professionnels de la médecine et de la santé contribuent de plus en plus à (re)constituer et comprendre divers mondes à travers les sciences humaines. Cet article brosse un tableau historique des sciences humaines tant en géographie qu'en sciences médicales et de la santé, en particulier la médecine : nous soutenons que les deux disciplines ont beaucoup à apprendre l'une de l'autre sur l'intérêt que chacune porte aux sciences humaines. En mettant l'accent sur le recours grandissant par les deux disciplines à la narration et à la mise en récit, nous faisons valoir l'idée que le déploiement des cadres et des impulsions fondés sur les sciences humaines ne peut pas être envisagé sans mener au préalable une réflexion analytique minutieuse et critique. Enfin, nous fondons cette étude du champ théorique sur des exemples empiriques tirés de travaux réalisés à l'échelle communautaire sur les risques et les avantages de la mise en récit et des arts visuels quand on se penche sur les aspects géographiques de la santé des peuples autochtones et colonisateurs dans le nord de la Colombie‐Britannique.  相似文献

Geography is perceived to be a relevant contributing discipline within a growing Canadian studies community in the United States, and the Association of American Geographers (AAG) retains a viable Canadian Studies Specialty Group. Since the early 1990s, however, the number of American geographers affiliated with Canadian studies organizations has not significantly increased: the community of scholars remains small and geography holds a peripheral position in terms of its actual contribution to US‐based Canadian studies programs. This article documents and interprets these trends using membership data collected by prominent professional organizations in Canadian studies and geography. It also explores the question of why American geography's Canadian regional specialists are not engaging formal Canadian studies initiatives in greater numbers. The observations that emerge suggest that a diversification of research themes in Canadian studies, particularly in the realms of environmental and physical science, would both increase participation by American geographers and enhance the field's ability to address pertinent aspects of the Canadian experience. Although observations presented pertain directly to the state of Canadian studies in American geography, they may also shed light on the lack of involvement by geographers in a variety of area studies fields in the United States and elsewhere.  相似文献

This invited essay responds to requests by the Suzanne Mackenzie Memorial Lecture Nominating Committee and by the former Editor of this journal to take stock of and provide intellectual‐historical context for the major preoccupations that characterized feminist urban geography in its early years, by means of a personalized reflection in light of the author's own positioning in those debates and interventions. The thread running through the article is that of the relationship between the ‘economic’ and the ‘social’ in urban geography. The last section briefly considers new challenges that neoliberalism poses for critical feminist urban geographies.  相似文献
