"It's our home" : expressions de la relation au territoire des Dane-zaa de Doig River (Colombie-Britannique, Canada)

Bénézet, Paul 19 April 2018 (has links)
Axé autour du concept de territoire, ce mémoire est une présentation de ce que cette notion recouvre pour un groupe de chasseurs-cueilleurs de l’ouest canadien. Installés depuis des millénaires sur les contreforts des Montagnes Rocheuses au nord-est de la Colombie-Britannique et en Alberta, les Dane-zaa (« le vrai peuple »), intimement engagés dans cet environnement, ont développé des savoirs et des techniques spécifiques adaptés à une gestion logique et durable du territoire et peaufinés par les générations successives. La relation entretenue recouvre cependant bien plus qu’une exploitation physique puisque les humains et les non-humains, voisins sur un pied d’égalité, interagissent dans un rapport d’échange et de respect. Depuis l’arrivée des Euro-canadiens et la signature du Traité 8 en 1900 lequel ordonna la création d’une réserve, le territoire des Dane-zaa, cet espace de vie, d’histoire et de mémoire, s’est vu fragmenter et est devenu le lieu d’enjeux et d’intérêts politiques et économiques souvent divergents et difficilement conciliables. / Focused on the concept of land, this master’s degree thesis is a presentation of what this notion represents for a group of hunter-gatherers of western Canada. Settled for thousands of years on the foothills of the Rocky Mountains in North-East British-Columbia and in Alberta, the Dane-zaa (“The Real People”), intimately engaged in their environment, have been developing knowledge and technics adapted to a rational and sustainable land management, generation after generation. However, this relationship does not only concern the exploitation of the resources the land provides, but also the bonds between humans and non-humans who share it. Since the arrival of the first euro-Canadians settlers and the signature of Treaty 8 in 1900 which ordered the creation of a reserve, the land of the Dane-zaa, their “home” and a space of history and memory, has been fragmented and has become the site of political and economic stakes and interests often divergent and which can hardly been reconciled.

Orders of Geo-Kinetic Manifestation in Ivan Doig´s The Sea Runners

Liste, Erika January 2013 (has links)
This phenomenological study presents a map of spatial forces in Ivan Doig’s The Sea Runners. The investigation calls attention to forms of space-experience that come across as a sense of embeddedness in environment. Events, places, feelings, and moods materialize as being nested within greater events and places that are likewise nested in even larger ones. The study shows that experience, place, memory, hope, and narrative have nested structures. The embedding of narrated realities within larger realities is identified as a mode of organization central to the text’s complexity. Even the smallest acts, events, moods, and feelings are set within larger ones with greater scope, reach, or extension. The literary force of The Sea Runners is made possible by a sustained presentation of complexly interlocking orders of embedding. These orders are co-ordinated and synchronized in terms of movement. The study shows how kinetic systems of circulation, vanishing, encircling, and transformation overlap and reinforce each other so as to create a comprehensive co-ordination effect that colours the presentation of landscape and travel. Movement is highlighted in the essay as a factor that makes it possible for these kinetic structures to be fused in various patterns of co-ordination. In The Sea Runners, place and motion complexly combine to shape the narrated flow of lived experience. In its various orders of fluctuation, space-experience flows in intimate association with life-feeling and movement-sensation. Certain basic kinetic categories are delineated as being at the heart of the text’s overall structure. The study brings its findings to a conclusion by discussing these kinetic categories of lived space as running parallel to categories of lived temporality.

Pétrofaciès, sédimentologie et architecture stratigraphique des roches riches en matière organique : étude multi-approches des formations Montney et Doig (Trias inferieur et moyen, Alberta - Colombie Britannique, Canada) / Petrofacies, sedimentology and stratigraphic architecture of organic rich rocks : insights from a multi-disciplinary study of the Montney and Doig formations (lower and middle Triassic, Alberta - British Columbia, Canada)

Crombez, Vincent 01 March 2016 (has links)
L’objectif de cette étude est d’affiner notre compréhension de la distribution des hétérogénéités de concentration de la matière organique dans les roches mères en se basant sur des affleurements et des données de puits provenant des Formations Triasiques de Montney et Doig (Canada). La méthodologie développée dans cette étude est la suivante : (1) la corrélation de forages sur les principes de la stratigraphie séquentielles, (2) l’analyse d’échantillons prélevés sur des affleurements, des carottes et des débris de forages avec un Rock-Eval, un ICP-MS/AES (3) l’intégration des résultats des analyses géochimiques et pétrographiques dans le cadre stratigraphique, (4) l’utilisation du code numérique DIONISOS pour restaurer l’architecture stratigraphique des Formations de Montney et Doig et tester plusieurs scénarios de productivité primaire et de restriction du bassin.Les formations de Montney et Doig ont été découpées en quatre séquences elles-mêmes regroupées en deux cycles de second ordre (A et B) séparés par un hiatus majeurs. Cette étude montre que les formations triasiques de l’Ouest du Canada se sont déposées dans un bassin actif et non pas sur une marge passive. L’intégration des résultats des analyses géochimiques et pétrographiques dans le cadre stratigraphique fait ressortir deux niveaux d’accumulation de la matière organique : une dans le FSST de la séquence A et une dans le TST de la séquence B. La modélisation avec DIONISOS montre un effondrement majeur des apports sédimentaires entre le Trias inférieur et moyen. Dernièrement, cette étude met en avant le contrôle de premier ordre de l’évolution géodynamique sur l’accumulation de la matière organique. / The aim of this study is to improve the understanding of sedimentary organic matter heterogeneities in unconventional plays, based on outcrop and well data from the Triassic Montney and Doig Formations. The workflow comprises four steps: (1) well correlations, based on sequence stratigraphy, (2) Rock-Eval VI and ICP-MS/AES analyses of outcrop, core and cutting samples, (3) integration of the analyses results in the stratigraphic framework, (4) a process-based forward modeling of the stratigraphic evolution of the basin with DIONISOS in order to test multiple scenarios of primary productivity and basin restriction.The stratigraphic architecture of the Montney and Doig Fms has been subdivided into four sequences gathered in two second order cycles (A and B) separated by a major time gap (approx. 2 My). This study shows that the deposition of the Triassic series on the Western margin of North America took place in an active structural context and not on a passive margin. The integration of the geochemical and petrographic analyses results in the stratigraphic framework shows that significant organic accumulations are located in the FSST of sequence A and in the TST of sequence B. DIONISOS shows a major drop of the sedimentary inputs between Lower and Middle Triassic that is interpreted to be linked to the regional geodynamic evolution and the early stages of the Canadian Cordillera orogeny. Lastly, this study emphasizes the first order control of the geodynamic evolution on organic rich accumulation.
