Full textA better understanding of the dynamic equilibrium between the vegetation and the fire recurrence is useful for Mediterranean ecosystems sustainability. The impacts of fire recurrence on vegetation, its flammability and fire behaviour, have been studied on a 50 years fire history on acidic soils in South-Eastern France (massif des Maures, Var department, France). A vegetation mosaics was described according to fire mosaics. Five classes of fire recurrence were defined, from zero to four fires with different time intervals. Time elapsed since last fire then the number of fires are the most important factors in observed modifications. Species and functional analyses confirm the resilience of most species which have been selected by a long fire history. However, some plant traits are negatively affected by fire recurrence, such as competitive strategy and zoochory. A resilience threshold can be estimated around three to four fires in 50 years. In high maquis, a very structurative species (Erica arborea L. ) dominates the stand and decreases light and space for the other species. Its cover and long life duration entail a decrease in the functional diversity, leading to a slackening in dynamics. Flammability experiments on non-disturbed litters show significant differences between the facies. The most flammable are the high maquis and medium maquis with a high biomass, characterized by very high values of combustibility and vertical propagation ability. Fire behaviour simulations indicate contrasts between low and open formations and high and dense formations. High maquis, medium maquis and cork-oak woodlands on maquis lead to high fire intensity and rate of spread. Fire recurrence mainly impacts on vegetation structure and subsequently fire behaviour. These data are useful to predict the relationships between fire and vegetation in a climatic and disturbance change context

Full textThis these is composed of three volumes. The first is the text, the other two are the maps, then diagrams and charts which illustrate the text. The text is divided into the introduction and four parts, followed by a very brief conclusion. The introduction includes two chapters: a geographical chart of " Massif des Maures" (geomorphology, relief, climatology, hydrography, and lines of communication), and a second defining problematic and methodology. Let us consider universal man during a period divided in three phases: 1789 to 1870 is the " long time " when man moved slowly - 1870 to 1945 is the " mutation time " which saw the introduction of machinery - 1945 to 1996 is the " short time " when everthing takes another size. We have put the man in a historical space which evolves according to several variables: the exploitation of earth in permanent evolution - work and social condition in time and space - possession of earth - demography according to evolution of space - habitation which evolves which man, space and social conditions. Following four parts: the first is the old mixed farming and forest system of exploitation, during the " long time " and the " mutation time " - the second during the " short time " is the system of exploitation of the same space which has opened up mass tourism - the third relates to the social conditions and the demography according to the mutation of economy - the fourth is the habitation which evolves in its situation and in its disposition in function of the managment of space. The conclusion points to the diversification of specialised relations which exist between man and space

Full textDue to the social and political issues about the restoration of burned forests, this work deals with the impact of forest fires on organic and inorganic matters from forested soils collected in Maures Moutains, taking into account the fire temporal recurrence. This studied site was chosen because every year it undergoes an important pressure from wildfire. Among the three main objectives, the first one was to highlight the impact of the fire frequency on the soil quality, studying more precisely the organic matter and some nutrients. Moreover, we wanted to find fire indicators among many elements and polycyclic aromatic hydrocarbons. Finally, we searched to develop a tool for the management and characterization of burned soils using near infrared spectroscopy. The sampling was done for 2 soil layers in 30 sites involving different fire regimes. After the repeatability test of the employed analytical methods, the results show that fires have an impact on soil. Generally, the fires preferentially affect soil surface layers in a qualitative and quantitative way. If the fires have an impact on the soils, it is usually negative because one year after the last event, the soils present losses of the organic pool and nutrients. In addition, some elements could be considered as potential fire indicators in the long term. Comparatively to the elements, the studied PAH with the lowest molecular masses seem to be good fire indicators in the short term. Lastly, this work enabled to validate and envisage the use of a tool for the burned soil management, by the NIR spectroscopy coupled to chemometrics treatments

Full textThis thesis aims to: (i) explore and evaluate several ways of living with fire in Mediterranean forests; (ii) appraise different evaluative frameworks for wildfire risk governance. The case study concerns the Massif des Maures (Var; France), a fire-prone territory where structural socio-economic transformations are coming about since 50 years now. The thesis consists of three main parts clearly distinguishable (thematically as well as methodologically). First part focuses on “Fire Economics”, that is, the set of theoretical concepts and methodological tools commonly applied by economists for the study of wildfire risk (C+NVC model, “most efficient program level”, etc.). We highlight up to three fundamental sophisms in such an evaluative framework. We thus underline its inadequacy for dealing with the complexity, uncertainty, ambiguity and incommensurability of wildfires phenomenon. The focus of the thesis moves then to the presentation of an alternative approach in which several semi-qualitative and integrated Scenarios are explored through an inclusive Multi-Criteria reasoning. Second part thus treats Environmental Scenarios, an approach which is first presented in a general way and whose application to our case study is then analysed in detail, from the very first interviews with local actors to the final scenarios generated with their participation. These scenarios are: (i) Technical Confrontation; (ii) Forest (re)Colonisation; (iii) Fire Domestication; and (iv) Collective Adaptation. Third part deals with Participatory Multi-Criteria Approaches (PMCA). We first present and contextualise these evaluative frameworks as an example of Value-Articulating Institution (VAI). We then apply to our case study a hybrid PMCA inspired from two approaches frequently used in social-ecological systems management and risk governance: Multi-Criteria Mapping and INTÉGRAAL Approach. The thesis concludes with several recommendations that could improve social acceptability of current fire management strategies and more generally, enhance fire risk governance practices

Full textThe tectonic evolution of the Southern Variscan belt is still poorly understood in comparison with that of the central European Variscan belt. That is mostly due to intense late-Variscan to Alpine re-working, which is particularly pervasive in the axial zone of the Alps. At odds, the Variscan rocks of the external domains of the Alps are little affected by the Alpine re-equilibration. For these reasons, these domains well preserve the Variscan record and are of the greatest importance for constraining the evolution of the Southern Variscan belt.This thesis is focused on the Variscan basement rocks in the Argentera-Mercantour Massif (Helvetic domain), Orobic basement (Southalpine domain), and Maures-Tanneron Massif (southern Alpine foreland). The latter is included as a benchmark for the Variscan belt just outside the Alpine area. The aim of the research is to provide new constrains on the Variscan and Alpine tectonic evolution of the external domains of the Alps, as well as of the Alpine foreland.This study required structural mapping (1:10.000 to 1:100 scale) integrated by microstructural, chemical, and mineral-chemical analyses. Metamorphic conditions that affected the Variscan basements have been estimated in terms of pressure and temperature and constrained in time by relative and absolute ages. By doing so, several stages of the Variscan and Alpine tectonics are here addressed, from early Cambrian to Tertiary times, and discussed in light of the geodynamic and paleogeographic reference models for both the Variscan and Alpine belts. The results refer to four main tectonic stages of Southern Variscan belt, from the subduction of the Variscan Ocean to the Alpine collision
