A new generation of greenways has emerged in recent years, the most ambitious of which are nationwide, interconnected networks of multi-use, multi-purpose greenways and trails, clustered under a single national vision. However, because these initiatives have been the focus of so few research studies, opportunities to glean lessons from their planning and implementation have been limited. This paper contributes to addressing this knowledge gap by presenting a comparative account of two networks, the Trans Canada Trail in Canada and Sendero de Chile in Chile. Using document analysis and interviews with officials closely involved in their development, the evolution of both networks is documented over time, emphasizing similarities and differences related to their planning and implementation. Both initiatives have faced significant challenges in reaching their connection goals and have availed themselves of a diverse range of opportunities and strategies to advance their agendas. A simple model of a virtuous cycle is proposed to highlight the positive feedback—between political and public support, sustained funding, partnership development, accessibility for urban residents, and connectivity of the network—generated by sustained network expansion over time. It is hoped that the insights offered from this analysis may offer guidance to inform the development of similar scale projects elsewhere.  相似文献

This article examines the epistemic practices of interpretive field geomorphology—that is, the in-the-moment act of “seeing the landscape” geomorphologically. Drawing on the philosophical works of Wittgenstein and Merleau-Ponty, it aims to bring to light the complex, multi-dimensional, knowledge-producing process of field observation and interpretation. Methodologically the study is based on geomorphologists' accounts of their fieldwork, gathered through questionnaire and interviews. By paying attention to what geomorphologists say they are doing in the field, interpretive field geomorphology is articulated as a combined cognitive, social, embodied, and affective experience through which understanding is arrived at. The paper thus sheds light on one part of what Brierley et al. call “the dark art” of geomorphological interpretation, and draws out implications in terms of researcher positionality, researcher training, and offering an epistemic justification for field-based pedagogies.  相似文献

De nouvelles formes de développement sont privilégiées dans certains espaces de la proche banlieue des principales métropoles canadiennes. Cette évolution est liée à la maturation de ces espaces sur le plan économique. Par l'étude d'un cas représentatif de cette maturation économique à l'échelle métropolitaine de Montréal, l'arrondissement de Saint-Laurent, nous mettons en valeur l'évolution des stratégies d'aménagement des acteurs du développement pour les deux principales phases de développement du territoire (1950–1980 et 1980–2000). Nous relions l'évolution sur le plan économique du cas étudié et les stratégies d'aménagement des acteurs du développement en nous référant à la thèse de la régulation. Par une méthode de collecte de données de type qualitatif basée sur une analyse documentaire et l'usage d'entretiens avec les acteurs du développement (du secteur privé et municipal), nous comparons les pratiques d'aménagement pour les deux périodes étudiées. En faisant appel à la distinction entre le fordisme et le post-fordisme pour caractériser la maturation économique, nous concluons que l'évolution sur le plan morphologique du territoire est marquée par le passage d'un aménagement fonctionnaliste à un urbanisme de créneau.  相似文献

The effects of medieval agrarian crisis on settlement and population were considered in a major interdisciplinary research project in Scandinavia during the 1960s and 1970s. Within this project, there were significant differences in methods used to calculate the extent of farm desertion between historians in the participating countries. The reliance on written source material within the Swedish team reflected the dominant approach amongst historians who made less use of map and landscape evidence than others. In this renewed investigation of the magnitude of farm desertion in the Late Middle Ages, focussing on the province of Jämtland in central Sweden, field survey of the physical landscape and some three thousand historical maps are used as evidence, alongside conventional written sources, such as official letters and taxation documents. The results indicate that the extent of farm desertion in medieval Sweden has been underestimated because Swedish scholars generally eschewed the use of the retrogressive method, which their Norwegian counterparts had been using since the 1940s. There is therefore good reason to reassess the desertion rates of medieval farms in other parts of Sweden as well, using traditional geographical source materials together with the documentary sources usually favoured by historians This may also hold for other parts of Europe as well. The rate of desertion is discussed in a wider context of settlement contraction and expansion in central and peripheral areas of Sweden, including the long drawn-out process of reclamation of the deserted farms (ödesbölen).  相似文献

Community‐based conservation is experiencing a crisis of identity and purpose as a result of a disappointing track record and unresolved deficiencies. The latter include over‐simplified assumptions and misconceptions of “community,” the imposition of externally designed and driven projects at the community level, a focus on conservation outcomes at the expense of community empowerment and social justice, and limited attention to participatory processes. New approaches are urgently needed to address these weaknesses and to counter a rising trend towards environmental protectionism and a preference for conservation approaches at an eco‐regional scale that threaten the interests of local and Indigenous communities. We propose that three core principles of community‐based participatory research (CBPR)—(1) community‐defined research agenda; (2) collaborative research process; and (3) meaningful research outcomes—hold much promise. Drawing on the experience of a research partnership involving the James Bay Cree community of Wemindji, northern Quebec, and academic researchers from four Canadian universities, we document the process of applying these principles to a community‐based conservation project that uses protected areas as a political strategy to redefine relations with governments in terms of a shared responsibility to care for land and sea. We suggest that basic assumptions of CBPR, including collaborative, equitable partnerships in all phases of the research, promotion of co‐learning and capacity building among all partners, emphasis on local relevance, and commitment to long‐term engagement, can provide the basis for a revamped phase of community‐based conservation that supports environmental protection while strengthening local institutions, building capacity, and contributing to cultural survival.  相似文献

The Innis model of staple production has been used as the framework for evaluating many Canadian resource trades. This paper argues that Japanese resource trade differs from that with Europe or the United States and that the distinct set of institutional arrangements governing Japanese resource trade requires the modification of the Innis model to recognize this new form of Canadian staple production and trade. The one billion dollars per annum Canada-Japan coal trade provides a detailed case study of the institutional complexity of Japanese resource trade, as revealed through corporate strategies, trade intermediaries, equity investment, loan arrangements, export contracts, and public infrastructure. Minority Japanese investments in joint ventures replace the dominant role of foreign capital in earlier versions of the staples model. The role of finance capital is highlighted by Japanese loans typically exceeding equity investments in size. The high transaction cost of negotiating hundreds of contracts is reduced through the use of sogo shosha (Japanese general trading companies) as intermediaries. Unequal relations are demonstrated by the greater risk borne by local investors as private firms provide equity and public institutions invest in infrastructure. The Quintette mine in northeast British Columbia highlights these risks. Overall, the complexity of the Japanese supply system reduces the bargaining power of any single supplier. However, the stability promoted by the security objectives of the Japanese supply system leads to long-term trading relations that can provide corporate cash flows and maintain community viability during cyclical downturns in the industry. Le modele d'lnnis sur la production des matieres premiéres a servi a analyser les effets du commerce des ressources naturelles au Canada. Le texte maintient que les echanges de ressources naturelles avec lelapon different de ceux qui lient le Canada aux Etats-Unis et à l'Europe, et que la particularité des structures servant à administrer le commerce avec le Japon nécessite une modification du modele d'lnnis vouéà l'analyse des effets de ce commerce. Le texte se penche sur le commerce du charbon entre le Canada et le Japon, dont la valeuratteint 7 milliard$ parannée. Cette étude de cas va permettre de saisir la complexité institutionnelle des échanges ayant trait aux ressources naturelles avec le Japon, perceptible dans les stratégies des corporations, la présence d'intermédiaires, les investissements, les modalités de prêts, les contrats d'exportation et les infrastructures. Les investissements minoritaires des japonais dans des entreprises conjointes remplacent le rôle dominant des investisseurs étrangers caractéristique des modeles antérieurs d'extraction des matieres premieres. Le rôle accru du capital financier est souligné par les prêts des japonais qui exddent habituellement leur achat d'actions. Les hauts cocits transactionnels lie's à la négociation de centaines de contrats est réduit par l'intermédiaire de sogo shosha (compagnies japonaises se spkcialisant dans les échanges entre corporations). Nous constatons l'exis- tence de rapports inégaux olj le gros des risques est assumé par les investisseurs locaux et les agences gou- vernementales qui assurent la mise en place d'infrastructures. La mine Quintette dans le nord-est de la Colombie-Britannique illustre bien ces risques. La complexité du systeme d'approvisionnement japonais réduit les atouts dans les négociations des fournisseurs pris individuellement. It demeure que la stabilité, qui découle des objectifs d'approvisionnement a long terme des japonais, permet d'établir des rapports d'échange durables qui garantissent aux entreprises des revenus persistants ainsi que la prospérité des localites olj se trouvent les opérations d'extraction. Ces localités se trouvent alors soustraites aux effets des cycles économiques.  相似文献
