Texto completo da fonteFrom the study of three alpine valleys (chamonix, tarentaise and ferrand), the author strives to demonstrate that spatial se and planning in the "high mountain" can be understood as a unique process of spatial territorialisation of social groupes. This process needs the production of immaterial structures, such as nomination of places which has been specialty studied by the author and material structures (agrarian structures, lines of communication, networks of ski-lifts and touristics trails). The parallel development of several processes of territorialisation creates the necessity of a relative definition of the different social groupes, what we call "relations of spatial appropriation", relations which can be proved conflictual

Texto completo da fonteSnow is labile. If it has always been marked by the seal of variability, the effects of climate change tend to make its presence more uncertain, or even to make it disappear. A first part of this doctorate consisted of exploring the relationships that have been constructed with snow, whether epistemological by the research carried out on the physical object “snow”, political by the planning programs constructed with it or spatial by the effects of its presence or absence on the scale of mountain territories. This first exercise made it possible to identify two major contradictory trajectories, immunity and improvisation, put to the test in three areas: the Queyras valley in the Hautes-Alpes department (France); Valpelline in the Aosta Valley (Italy) and the profession of high mountain guide, whose practice is marked with the seal of multi-spatiality.Snow has conditioned the formalization of a very structured, developed and planned tourist model, which in turn determines the functioning of numerous mountain spaces and territories. Its absence or greater uncertainty reinforces the deployment of immune strategies of a development model which tends towards stability and rational forecasting. On the other hand, a kaleidoscope of indeterminate and heterogeneous development modes is developing at the heart of various mountain territories, finalized by issues linked to habitability. We will thus follow the intoxicating hypothesis of territorial improvisation

Texto completo da fonteThe railroad track, booming, at the end of the 19th century in the industrial countries of Europe, allowed the aristocracy and the " nouveaux riches " to move more quickly around the continent. They soon flocked to the banks of the lake " Léman ", particularly in the region of Montreux, known under the name " Rivièra Lémanique " which was covered very quickly by sumptous hotel construction. But the mountain, very close, attracted also the high society of the " Belle Epque " who wanted to be able to go there easily. To do that, appropriate means of communication were needed. By the end of the 19th century, a concession was given for a railroad line " Montreux-Oberland Bernois ". By 1901, this railroad track went up to the village " Les Avants-sur-Montreux " (978 meters high) then with service to all the inter-mountain valleys. The arrival of that train in the villages – for the important movement of tourists it created – elevated them to a well-known status as compared to Gstaad, and made fashionable for " High Society " of the time. A region was born, that of M. O. B. Growing each year without ceasing. From then on, consideration of that region was necessary for successful tourism. Finally, regardless of the chagres in tourism, the company M. O. B. Can find solutions, by adapting itself to the needs of this regional entity on one hand, but on the other hand, by extending skillfully their area of influence to the Riviera Lémanique

During the snow-free season, walking upon areas caused displacement of materials compaction of soils along with a significant decrease in the number and density of vegetal species. Some relationships between compaction and trampling are shown : - evolution of porosity on a level run with the intensification of trampling. - infiltration rates decrease rapidly with trampling to a minimum ratio.

Texto completo da fonteThe subject of this thesis is security in high mountain. This work reveals how the security initiatives are built and what the regulation mechanics are. With this aim in view, the research focus on the knowledge which influences on this mechanisms. This knowledge is studied from three points of view. The first one is about the daily life, the second one is about the institutional world and the last one is about the general relationships with risk. Moreover, this research studies the weight of the "non rationals logics" as opposed to "interests logics" (more or less economics) which influence the collective organisation of security. The high mountain is a good illustration with its little economic stakes, a limited scientific knowledge and a very strong mythical potential. The socio-anthropological approach is particularly interesting to identify this different "non rational" dynamisms

Texto completo da fonteAssessment and comprehension of gully erosion dynamics at their temporal and spatial scale in Badlands (marl’s geology, south of French Alps need fast and easy reproductible methods of characterization of these phenomena. We tested two approaches of spatial observation in order to accomplish this goal: an aerial approach by stereophotogrammetry from unmanned aerial vehicle (drone) images, and a terrestrial approach by ground laser scanner. For the aerial approach an adequate combination of ground preparation, systematic errors compensation (resulting from image acquisition) and an image matching strategy enabled us to obtain a drone DTM with resolution, accuracy, and hydrologic coherence within the limit of the data (average image ground resolution 3 cm). In regard to the terrestrial approach, results of LiDAR measurement test on different geometric surfaces show that the noise is of 1 cm from a measure distance of 30 m. The application of a simple average filter in a regular grid of 1 cm makes it possible to reduce the noise and also to recreate geometric forms of more than 3 cm large. The “advantage-constraints” ratio between these two approaches shows us that the aerial approach produces DTM with better extent and continuity, while the terrestrial approach produces more precise and detailed DTM. These results reveal the enormous potential of drone images for the development of inexpensive DTM. In addition, ground LiDAR arises as an interesting topographic surveying system for the monitoring of elementary processes of gully erosion, allowing for very detailed measurements in space and time

Main objectives of this work relies on (i) analyzing the emergence of a biological knowledge at the limit of life and (ii) on studying the dynamics of living organism, in order to assess reflection on terrestrial habitability. This project is based on vascular plants as a biological model in both frameworks: the geo-history, with a specific emphasis on the geography of science; and the scientific ecology, including botany, taxonomy, biogeography and historical ecology. This hybrid project aims to understand how high mountains constitute unique scientific locations as well as a space highlighting biodiversity changes. It aims also to understand ho vascular plants may be a relevant biological group to better understand terrestrial habitability and biodiversity evolution in the upper limit of life

Texto completo da fonteTrace metal enrichment factor values and lead isotopic ratios recorded in sediments of high mountain lakes (Aumar et Orédon, Massif du Néouvielle, Hautes-Pyrénées, France) allow us to identify anthropic historical contaminations. Pb and Sn contamination, dated back to the roman period, are probably originating fom mining activities in the south west of Spain. Lead-silver mining activities fom Germany (13th century) are correlated to Pb and Sb (seventies) are the consequence industrial development. The use of leaded gasoline and its decrease are also observed. These lake sediments have recorded large scale heavy metal contaminations but also local anthropic activities of the valley. Hydroelctric development of the valley (1900-1950) and the creation of an artificial dam disturbed the sedimentary conditions of lake Aumar. Lake Oredon sediments recorded Ni and Cu contaminations (1930-40) as a consequence of the buildingof the Cap de Long dam. This study also presents new ICP-MS developments : (i) correction of poly-atomic oxide interferences when determining transition elements, (ii) precise enough Pb isotopic ratios for discriminating Pb sources (anthropic vs natural), (iii) direct multi-element analyses in sediment matrix laser ablation -ICP-MS

The method put forward is a space-time study of the medium-height areas of the central pyrenees. It appears that the biological cycle of the bees is closely adapted to its environment. Space is thus used and shared according to the needs of the colony. A first cartography of honeybearing plants resources has been suggested as we have analyse the honey-bearing flowers potentiality of the area which has been studied, in connection with a typology of the honey-bearing species. Moreaver various improvements and or plantations have been suggested so as to favour a continuous flowering and to increase the productivity of the area. As a conclusion, a method of analysis of honey-bearing plants is proposed. This localised study brings into light the possilibility to set up a cartography of honey-bearing potentialities of an area allowing the improvement of zones and environments where the decline of agriculture is important

Texto completo da fonteThis doctorate study aims to assess the psychological factors of vulnerability to risky sports behaviours in future high mountain guides. It focuses on motivational and emotional variables linked with self-regulation and personality traits, and is based on three studies. The first study helps assess the specific psychological profile of future high mountain guides (N = 189) compared with both the general population and individuals engaged in other risky behaviours (i. E risk-taking athletes, N = 170 and firemen N = 121). The second study helps identify the role of motivational, emotional and personality variables in determining unsafe behaviours among those people taking risk at work (N = 188). The final study helps test the effects of risky behaviours on future mountain guides’ emotional experience (N = 118). Results show that future mountain guides are very far from the psychological profile of firemen and other individuals engaged in risky behaviours, Their characteristics are more like risky sports athletes’. On the whole, these individuals have a rather well-balanced psychological profile, although they may experience relational and emotional difficulties (Study 1). Besides, careless future high mountain guides are typically open to experiences, have a high lack of consciousness and tend to deliberately ignore self-conscience (Study 2). Their involvement in their practice (i. E mountain runs) together with a careless behaviour are their own approach to emotional self-regulation (Study 3)

Texto completo da fonteThe Haute Auvergne, located in Cantal, and Limousin Mountains across North of Corrèze, South of Creuse and far east of Haute Vienne, represent the study area on which this research was conducted. These are medium sized mountain territories, which represent real conservatories for all period installations, notably for Protohistory. This study area is therefore a real laboratory allowing statistic and spatial approaches. Furthermore, these territories offer numerous wetlands and bogs by which paleo-environmental data are made available. Thus, these supplements the information provided by the metallic artefacts originated from non-funeral depositories or isolated discoveries, by the settlements, notably by the hillforts, but also by the funeral domain, well represented through the good conservation of barrows cemeteries. This research has a thematic approach on these many data, for the Bronze Age but also for the Iron Ages, to apprehend the question of the occupation of these special topographic contexts on the long term, the Man/environment Interaction, and the connections between high grounds and lower areas. We here offer an essay on protohistoric geography that will lead to discussions and new research perspectives

Texto completo da fonteThis dissertation focuses on English for Specific Purposes and, more particularly, on the study and characterization of specialized professional domains and their discourses in English-speaking countries. It is a contribution to the characterization of mountaineering English, via the study of the specialized domain of American mountain guides. To this end, a model for the characterization of specialized domains and their discourses was designed and tested. Part 1 presents the theoretical and methodological framework of this research. It begins with an epistemological reflection on the status of the researcher and his/her object, and then moves on to the description of the process by which specialized domains can be studied, based on a consideration on the methodological framework, and more particularly, on the nature and value of fieldwork. Part 2 focuses on the characterization of the specialized professional domain of mountain guiding and begins with a historical account of mountaineering in the US. It deals with the training and work of professional mountain guides and aims to identify and analyze the stakes for the profession today. Part 3 attempts to characterize the discourse of mountaineering and mountain guiding. Some features of this specialized discourse are discussed, from a terminological point of view, and finally, a typology of the different written genres of the specialized discourse is proposed

Texto completo da fonteThe use of weather radar data to estimate rainfall accumulations is often complicated by the heightof the measurement. This is particularly true in mountainous areas where the beam is very farfrom the ground either because the radar are installed at high altitude or because the lowest elevations are partially or totally hidden or both. The method conventionally used in operationalsystems (and in particular at Météo-France) to extrapolate reflectivities to ground level, does notallow to consider some processes too complex to be modeled easily, such as evaporation orstrengthening of precipitation under the radar beam. In addition, the spatial variability of theprecipitation profiles is not taken into account, limiting considerably the performance of the rainfallestimation by the algorithm in both plains and mountainous regions. It is by identifying these gapsand limitations that this thesis was written, with the aim of developing an innovative method forestimating the rainfall accumulations. The idea is to take advantage of the ability of MétéoFrance's high-resolution nowcasting model (AROME-PI) to produce realistic precipitation profiles.These profiles are used to estimate the most probable one according to the available volume observations, and to use it to estimate the precipitation at the ground. In order to do so, we relie ona radar simulator that simulates the reflectivity from the model prognostic variables (hydrometeorcontents, temperature ...), and that takes into acount the radar beam geometry. The first part ofthe thesis focused on the implementation of a Bayesian method to retrieve the most relevantsimulated profiles of reflectivity which are then used to estimate the rainfall rates and accumulations. Two complex stratiform situations were studied to test the performance of the newscheme and to highlight the limitations of the correction currently used at Météo-France. Thesensitivity of the results to the weight given to the lowest elevations in the method as well as to thenumber of simulated profiles used was conducted. The second part of this thesis presentsimprovements brought to the parametrization of the bright band in the radar simulator while keeping the coherence with the microphysics scheme ICE3 implemented in AROME model. Thesimulated reflectivities were evaluated on different case studies. The biases identified have beenpartially corrected through the development of a suitable statistical method, allowing thedevelopment of a more robust simulated dataset. Finally, the last part of the work focused onevaluating the potential of the method in mountainous areas. First tests were carried out on anidealized case over flat areas for which the lowest elevation was deliberately hidden. There flectivity behind this fictive mask was then reconstructed and compared with the reflectivitiesactually observed. Next, the new method was applied to a convective case and a stratiform caseover mountainous areas. A three-dimensional evaluation of the performances from the quasivertical profiles of the Xport radar from IGE, the rain gauges as well as the SAFRAN reanalysis (amodel producing analysis and forecast of meteorological quantities adapted for the mountain),helped to evaluate the full potential of this new approach for estimating the rainfall accumulationsin complex terrain

Texto completo da fonteWater resources management is a complex issue for several reasons : multiplication and concentration of uses in a situation of interdependence, diversity of socio-economic users, responsibilities split between public and private, sectoral and sometimes mutually contradictory regulations overlap, opposition of representation systems. . . This complexity relates to the relevance and feasibility of integrated and sustainable water resources management in mountain watersheds at a local level. Is this the solution to the management problems in such areas, i. E. Can it provide sustainable solutions to reconcile economic use and water resources conservation? We have chosen the "systems" approach applied to the "Giffre" watershed for holistic understanding of water resources management systems specific to mountain areas

Texto completo da fontela potentialité de ces stations forestières artificielles. Cette étude se situe dans ce cadre général de dynamique de la biodiversité et de changement des pratiques traditionnelles de gestion et de production vers la gestion durable des peuplements forestiers favorisant les espèces autochtones.
L'analyse phytoécologique montre que : (i) La zonation des peuplements forestiers dominants sur le versant nord de la montagne de Lure n'est pas toujours en rapport avec le cortège floristique associé ; (ii) le peuplement de pin noir montre la richesse spécifique en espèces patrimoniales la plus pauvre. Par contre, le peuplement de Abies alba en mélange avec le hêtre présente la richesse spécifique la plus élevée ; (iii) Certains travaux sylvicoles peuvent maintenir les espèces patrimoniales, comme les coupes progressives dans la pinède et les coupes jardinatoires en petite surface dans la hêtraie et la hêtraie sapinière.
L'approche expérimentale sur les potentialités de régénération des principales essences forestières démontre que l'absence du Abies alba dans la partie basse de la montagne (800 m) est due à un problème de dispersion (absence de semencier alentour) et non à des contraintes écologiques. Cette absence peut être attribuée à la distribution géographique des refuges pendant les glaciations quaternaires, mais aussi à l'effet de l'anthropisation qui a commencé avec le développement des sociétés sédentaires du Néolithique.

To contribute to this question of sustainable development, understood as a global approach to developmental and environmental problems, two sites of study were chosen in mountainous and forest areas on either side of the mediterranean. The analysis devoted to an area of study in Tunisia (the Khroumirie), which is characterised by high rural density and environmental degradation, demonstrates that the major obstacle to development and resources preservation lies in the land status of the forests and in the rigid forestry policy carried out. Added to this are the lack of an endogenous dynamics of development, the failure of outside intervention to initiate a real development process, as well as the lack of development policies conceived globally, at a regional level. The analysis devoted to the French region of study (the Prealps of digne), which represents an extreme case affected by rural depopulation, throws back into question the perception of this region as a vacant area and shows the multitude of participants involved, resulting in a superimposition of multiple uses anf conflicts of interest. These two regions illustrate two different facets of the problematics of sustainable development in rural areas. The samplings from regions north and south of the mediterranean enable us to stress certain determinant criteria with respect to the difficulties encountered, in particular, the question of the link between exogenous and endogenous dynamics. The analysis results in the formulation of certain proposals intended for intervention and of certain methodological orientations towards an approach in terms of sustainable development, notably through an examination of the practices ans strategies of the participants involved

Texto completo da fonteThe research aims at the determination of the hydrological and erosional response of a small mountain catch ment to a rainfall event. It leans on the data and observations from the Draix field laboratory. The work analyse the processes and factors that control the response and discuss their relative importance. Several spatial scales are investigated : the plot scale, the slope gully scale, the small basin scale. Through the statistical analysis of the data (1985-2003), the high non-linearity of the responses is pointed out. Specifie field work (rainfall simulations, measurements under natural rainfall events, field surveys of the channel network) allows the interpretation of the response in term of erosion and sediment transport processes. A first attempt of modelling with the ETC model (Erosion des torrents en crue) developed by Cemagref, is conducted to test the model ability to reproduce the spatial and temporal patterns of the erosion response observed in the field work

Texto completo da fonteFive sedimentary sequences have been studied in the Mont Lozère with the aim to reconstruct the landscape dynamics and the land-use through the longue durée. The use of a multi-proxy analysis has allowed us both to identify distinct rhythms of human-induced landscape shift and to establish the local/regional extent of these changes. The use of high spatial, chronological and analytical resolution has enabled a correct integration of the results of this research with those supplied by the PCR-Mont Lozère project. As a result, a series of land-uses in a mountain environment from the Neolithic to present time has been proposed. A long history of socio-environmental interactions in Mont-Lozère is evidenced. A first shepherding phase in Early Neolithic (4550-4400 cal BC) has been evidenced. During Late Neolithic pastoral practices and related slash-and-burn strategies attain its highest activity. In the Iron Age Period a noticeable deforestation of both foothills and higher environments takes place as a consequence of the overall increase farming and metallurgical activities. Forest clearances increase even more during High-Medieval times, at the same time that farming activities reinforce. During the Middle Ages a more complex and diversified land-use system, including farming, metallurgy, mining and charcoal production, is recorded. The development of farming activities in the Late Medieval resulted in a more evident forest clearance of the Massif. This area remained unchanged until the 19th century, when the decay of agriculture and shepherding occurs and forest replanting in Mont Lozère is recorded. The history of highland herb communities of Nardus stricta correctly matches the main phases of land-use and underlines the key-role of farming in the genesis and evolution of this cultural landscape
Se han estudiado cinco secuencias sedimentarias en el Mont Lozère con el objetivo de reconstruir la dinámica paisajística y los usos del suelo en la longue durée. La utilización de un análisis multiproxy ha permitido determinar los principales ritmos de antropización y establecer su carácter regional y/o local. La alta resolución espacial, cronológica y analítica hapermitido la integración de resultados con aquellos obtenidos en el marco del PCR-Mont Lozère y proponer los usos de la montaña que han modelado el paisaje cultural desde el Neolítico hasta la actualidad. Se ha evidenciado una larga historia de las interacciones socioambientales en el Mont Lozère, con una primera fase de carácter agropastoral en el Neolítico Antiguo, en ca. 4550-4400 cal BC. El Neolítico Final es una fase de marcado impacto agropastoral en la que se generalizan las quemas para abrir claros en el bosque. En la Edad del Hierro se inicia una marcada deforestación en el piedemonte y los espacios de altitud, coincidiendo con un desarrollo agropastoral y metalúrgico. En el periodo altomedieval se amplifican las deforestaciones coincidiendo con un marcado incremento de las actividades agropastorales. En la Plena Edad Media se evidencia un sistema diversificado que implica metalurgia, agricultura, pastoreo, minería y carboneo. El desarrollo agropastoral de la Baja Edad Media supone una marcada deforestación en el macizo que se extiende hasta mitad del s. XIX, momento en que se inicia el declive del agropastoralismo y empiezan las reforestaciones en el Mont Lozère. La historia de las formaciones herbosas con Nardus stricta de los espacios somitales sigue estas principales fases de antropización y revela el papel clave del agropastoralismo en la génesis y evolución de este paisaje cultural
