description Publicationkeyboard_double_arrow_right Doctoral thesis 2016 FrancePublisher:HAL CCSD Funded by:UKRI | Net Zero Teesside OnshoreUKRI| Net Zero Teesside OnshoreAuthors: Stolyarova, Elena;Little research has been done to date on French households’ preferences for energy retrofits in the dwelling. However, the economic role of these choices is crucial for implementing an effective and realistic energy policy in the residential sector, both in terms of proposed aid and targets. Are households interested in retrofits with high energy-savings potential? How much are they willing to pay and is it sufficient to cover the up-front costs? How many households have no choice of heating system, and what is their profile?This work sets out to answer these questions empirically using discrete choice models. It starts by analyzing the technical, socio-demographic and spatial constraints that face households and create barriers to domestic energy choices. A method to detect household constraint is devised and applied to the choice of space heating system in 2006 and 2013. The second stage analyzes household preferences for heating equipment and retrofits. This second part is based on a discrete choice experiment specially carried out for this research among 2,000 households. This work sheds light on households’ preferences and heterogeneity, as well as their willingness to pay, the implicit discount rate and other economic impacts. Les préférences des ménages français pour les travaux de rénovation énergétique dans le logement ont été peu étudiées jusqu’à présent. Or, elles sont la clé d’une politique énergétique efficace et réaliste pour le secteur résidentiel, tant au niveau des aides proposées, qu’au niveau des objectifs à réaliser. Les ménages sont-ils intéressés par des travaux à fort potentiel d’économie d’énergie ? Combien sont-ils prêt à payer et est-ce que c’est suffisant pour couvrir les coûts réels ? Combien de ménages n’ont pas le choix de leur mode de chauffage et quel est leur profil ?La thèse s'attache à répondre à ces questions de façon empirique à l’aide de modèles de choix discrets. Il s’agit, dans un premier temps, d’analyser les contraintes techniques, sociodémographiques et spatiales que rencontrent les ménages et qui entravent les choix énergétiques dans le logement. Une méthodologie de détection des ménages contraints a été proposée, puis appliquée au choix du chauffage en 2006 et 2013. Dans un deuxième temps, les préférences des ménages pour les équipements de chauffage et les travaux de rénovation ont été analysées. Cette deuxième partie utilise une enquête expérimentale qui a été réalisée spécialement pour ce travail de recherche auprès de 2000 ménages. Ce travail a permis de comprendre les préférences des ménages, leur hétérogénéité, et d’en déduire les consentements à payer, les taux d’actualisation implicites et les différents effets économiques.

Le protocole mis en place pour cette méthode implique l'utilisation de huit complexes "sondes", obtenus par des opérations de symétrie à partir de l'état de transition de la réaction de transfert d'un atome d'hydrogène entre le nicotinamide et la lumiflavine. Ces complexes sont positionnés dans le site actif avec le groupe prosthétique comme référence et dans chaque cas l'énergie d'interaction protéine-ligand est évaluée par la fonction de score implémentée dans le logiciel de docking utilisé (AutoDock). L'énergie d'interaction la plus favorable permet d'identifier la face du groupe prosthétique accessible pour la réaction enzymatique dans le site actif. La méthode PredFace a été validée par l'analyse de l'ensemble des structures de la Protein Data Bank contenant des groupes prosthétiques de la famille des flavines (2170). Le protocole mis au point est très rapide (moins d'une minute), ce qui nous a permis de développer un site web afin de mettre cette méthode à la disposition de la communauté.La seconde méthode, ProsthDock, est une nouvelle méthode de docking basée sur le mécanisme d'une réaction enzymatique catalysée par un groupe prosthétique et guidée par la présence de ce groupe prosthétique dans le site actif de l'enzyme. Le développement de cette méthode a été motivé par le fait que les méthodes actuelles de docking, en présence de groupes prosthétiques, se révèlent incapables de produire des poses correctes pour des substrats, en accord avec les réactions enzymatiques. Afin de remédier à ce problème nous avons ajouté à la fonction de score classique un terme supplémentaire, qui rendra compte de l'interaction du ligand avec le groupe prosthétique. Dans un premier temps, nous avons construit un modèle simplifié du complexe NADH/FMN et calculé l'état de transition de la réaction de transfert d'hydrogène entre les deux partenaires. Des surfaces d'énergie potentielle pour cette réaction ont été calculées en variant la distance, l'angle et l'angle dièdre entre les deux réactifs. Un docking sous contrainte est ensuite réalisé et en fonction du positionnement de chaque pose de docking dans le site actif le terme supplémentaire de la fonction de score est calculé à partir des surfaces d'énergie potentielle, ce qui nous permet de modifier le classement des résultats de docking en favorisant les poses qui sont en accord avec la réaction enzymatique. During this PhD thesis we developped two new molecular modeling methods applied to enzymes containing flavin-type prosthetic groups.The first method, PredFace, predicts the stereochemistry of products from a reaction catalyzed by enzymes containing prosthetic groups, by automatically identifying the solvent-exposed face of the prosthetic group. The protocol involves the use of eigth complexes as "probes", obtained by symmetry operations starting from the transition state of a hydrogen atom transfer reaction between nicotinamide and lumiflavin. These complexes are positioned in the binding site with the prosthetic group as reference and the energy of the protein-ligand interaction is evaluated by the scoring function implemented in the docking software (AutoDock). The most favorable interaction energy allows the identification of the prosthetic group face that is available for the enzymatic reaction in the binding site. The PredFace method has been validated by analyzing all the structures in the Protein Data Bank containing flavin-derived prosthetic groups (2170). This method is very fast (less than a minute), which allowed us to develop a web site open to the scientific community.The second method, ProsthDock, is a new mechanism-based molecular docking method guided by prosthetic groups present in the active sites of enzymes. The development of this method was motivated by the incapacity of the currently available docking methods to provide, in the presence of prosthetic groups, ligand conformations that are compatible with the enzymatic reactions. In this regard, we have added a new term to the classical scoring function, to take into account the interaction between ligand and prosthetic group. We have built a simplified model of the NADH/FMN complex and calculated the transition state of the hydrogen transfer reaction between the two partners. Potential energy surfaces have been calculated for this reaction by variating the angle, diedral angle and distance between the two reaction partners. A subsequent docking with constraints provides binding site conformations of the ligand for which the new term of the scoring function is calculated using the potential energy surfaces. This results in a new ranking of the docking poses, favoring those in agreement with the enzymatic reaction.

For this reason, an accurate physical and perceptual prediction of wind turbine noise is of crucial importance for the design and deployment of modern horizontal-axis wind turbines. In the present work, we discuss a novel methodology for the far-field propagation and auralization of wind turbine noise in complex rural environments. First, the sound sources are modelled analytically using a RANS-based Amiet’s theory, accounting for leading- and trailing-edge noise. Secondly, a geometrical ray-tracing solver is used to compute the multiple source-receiver paths and evaluate the directivity gain. The pressure time signal of the equivalent source is then reconstructed using spectral shaping synthesis. Finally, the Harmonoise ray-based method is used to apply the noise attenuation due to atmospheric absorption, ground barriers, ground effects, and meteorological conditions. Also, the varying propagation delay of each source-receiver path is implemented in the time domain using appropriate interpolation techniques. The obtained audio signals are evaluated for different listener locations and operating conditions of the wind turbine.

First, the sound sources are modelled analytically using a RANS-based Amiet’s theory, accounting for leading- and trailing-edge noise. Secondly, a geometrical ray-tracing solver is used to compute the multiple source-receiver paths and evaluate the directivity gain. The pressure time signal of the equivalent source is then reconstructed using spectral shaping synthesis. Finally, the Harmonoise ray-based method is used to apply the noise attenuation due to atmospheric absorption, ground barriers, ground effects, and meteorological conditions. Also, the varying propagation delay of each source-receiver path is implemented in the time domain using appropriate interpolation techniques. The obtained audio signals are evaluated for different listener locations and operating conditions of the wind turbine.

Dès que la pente dépasse 5 %, les matériaux érodés sont redistribués dans la zone toujours en eau, contribuant au « trophic upsurge » et à la sédimentation.

L’influence écologique de l’apport de nutriments associé à la redistribution des sols pourrait être significative dans les environnements oligotrophes. On connaît très mal l’évolution des sols ennoyés au fond des retenues. Des observations préliminaires effectuées sur la retenue de Sarrans montrent que les sols conservent leur structure d’origine. Elles suggèrent aussi que des sols bruns de prairie, ennoyés en permanence depuis 80 ans, ou exondés occasionnellement, ont perdu 30 % de leur carbone, par minéralisation.[br/] - Dynamique à long terme : A long terme, ce sont les sols du bassin versant et de la zone de marnage en pente faible qui influencent l’écologie des retenues. Les sols du bassin versant dans la mesure où le contexte écologique influence l’érosion et l’apport de nutriments. Les sols de la zone littorale dans la mesure où ils soutiennent une production végétale, qui peut contribuer à filtrer l’eau, mais aussi à l’alimenter en carbone organique minéralisable. Il semble que l’émission de gaz à effet de serre par les réservoirs est, toutes choses égales par ailleurs, plus importante que celle des lacs naturels, probablement en raison de la forte sédimentation, et des variations de pression qui favorisent l’émission de CH4, en particulier lors du passage en turbine. Reservoir establishment results in the submersion of soils and vegetation. Their ecological evolution follows 3 main phases.[br/] - Initial: carbon and nutrients stored in living and dead vegetation biomass supply for a rise of the trophic level and productivity of the lake. During this phase, named « trophic upsurge », which duration and intensity are variable, water anoxia, CO2 and CH4 emissions also rise especially when temperature is high.[br/] - Mean Term: Water level fluctuates according to seasonal energy needs. Waves erode submerged soils along the shoreline. If the slope is steeper than 5%, soils are redistributed downslope and this flux contributes to the trophic upsurge and to sediment accumulation. These phenomena have been poorly studied and quantified. Our measurements at Sarrans reservoir suggest that soil redistribution is a major contributor to sediment accumulation. The ecological influence of carbon and nutrient inputs to the lake may be significant in oligotrophic environments. The evolution of permanently submerged soils is poorly known. Preliminary measurements at Sarrans reservoirs show that grassland cambisols (almost) permanently submerged have lost 30% of their original carbon store since impoundment.[br/] - On the long term, both catchment soils, through erosion and nutrient supply, and soils of the littoral zone, which support vegetation communities, influence reservoir ecology. The accumulation of sedimentary carbon in reservoirs appears much higher than in natural lakes, even eutrophic, and reasons for this are many. Greenhouse gas emission is also higher, because of higher sedimentation rate and increased water level fluctuations that favour methane bubbling and water degassing at the turbine outlet.

Le changement climatique exige une compréhension de son fonctionnement pour bâtir des politiques de gestion efficaces, car la variabilité climatique contemporaine a engendré des bouleversements des écosystèmes naturels et produit une désarticulation sociale. Il est donc nécessaire de revisiter certains concepts clés (dégradation, ressources naturelles, acteurs, etc.), avant d'examiner la réalité de la dégradation environnementale, au regard de facteurs peu souhaitables par rapport auxquels il faut pourtant essayer d'esquisser un futur désirable. Les dynamiques environnementales en cours génèrent, en effet, des mutations peu avantageuses et conduisent à des conflits redoutables sur l'eau, la terre et toutes les autres ressources dites naturelles. Dès lors, de nombreux défis se font jour ; ils appellent des solutions qui tiennent compte à la fois de l'illusion et du forçage du destin, car les expériences douloureuses imposent la prudence, mais les potentialités indiscutables fondent, a contrario, de réelles ambitions de sortie des situations difficiles dans lesquelles se trouve l'Afrique. Il s'agit d'un pari sur l'avenir, pour le continent, en tablant d'abord, sur une triple durabilité (institutionnelle, socio-économique et environnementale) mais aussi, sur sa capacité à s'adapter à l'adversité du changement climatique et à améliorer l'utilisation peu efficiente de ses ressources naturelles par une option claire et holistique pour les stratégies d'intégration régionale. C'est le miracle que l'Afrique se doit de faire dès à présent, et pendant ce siècle ! Mots clés : environnement, dégradation, changement climatique, ressources naturelles, acteurs.

Les bilans d'eau et d'énergie à la surface des continents y sont calculés à l'aide de modèle de surface continentale (Land Surface Model, LSM). Ces dernières années, l'intérêt d'utiliser un LSM sophistiqué pour modéliser le climat terrestre s'est affirmé, notamment au niveau des régions tempérées qui abritent des zones de transition où l'évapotranspiration est limitée d'une part par l'énergie d'autre part par l'eau disponible. Le site instrumenté du SIRTA mesure de nombreuses variables atmosphériques permettant de valider un modèle climatique en un point. Le SIRTA dispose également de données d'humidité du sol utilisées pour la première fois dans cette thèse. Ces données révèlent la présence d'une nappe perchée, en accord avec une campagne de mesures géophysiques réalisée durant cette thèse. Les données du SIRTA sont confrontées à des simulations régionales qui sont réalisées à l'aide du LSM ORCHIDEE couplé à un modèle atmosphérique. Nous développons la possibilité d'imposer une nappe au sein du sol modélisé par ORCHIDEE, ce qui permet de soutenir l'évaporation en été au SIRTA, en accord avec les observations. Nous explorons différentes hypothèses hydrologiques qui entrainent une augmentation de l'évaporation à l'échelle de l'Europe de l'Ouest et impliquent une augmentation des précipitations ainsi qu'un refroidissement de l'air. Ces hypothèses sont également testées lors de simulations globales afin d'en étudier l'influence sur les caractéristiques du climat et du changement climatique causé par une augmentation de gaz à effet de serre. General Circulation Models (GCM) are tools which allow studying climate at large scale. Water and energy budget over continental surface are calculated by Land Surface Model (LSM). Interest on using a sophistical LSM to simulate earth climate grew up last years, in particular in transition area, where evaporation is limited on one side by energy and on other side by available water. The instrumented site of SIRTA observes many atmospheric variables and allows validating a climate model on one point. The SIRTA have also soil moisture data which are used for the first time in this thesis. These data reveal a shallow water table, according to geophysical campaign conducted during this thesis. Data from SIRTA are confronted to regional simulations produced with the LSM ORCHIDEE coupled to an atmospheric model. We develop the possibility to impose a water table in the soil modeled by ORCHIDEE, which allows maintaining evaporation during summer at the SIRTA, according to observations. We explore different hydrologic hypothesis which conduct to an evaporation increase at Western European scale and also involve precipitation increase and air cooling. Theses hypothesis are also tested in global simulations to study effects on climate and on climate change due to an increase of greenhouse gases.

description Publicationkeyboard_double_arrow_right Doctoral thesis 2016 FrancePublisher:HAL CCSD Funded by:UKRI | Net Zero Teesside OnshoreUKRI| Net Zero Teesside OnshoreAuthors: Stolyarova, Elena;Little research has been done to date on French households’ preferences for energy retrofits in the dwelling. However, the economic role of these choices is crucial for implementing an effective and realistic energy policy in the residential sector, both in terms of proposed aid and targets. Are households interested in retrofits with high energy-savings potential? How much are they willing to pay and is it sufficient to cover the up-front costs? How many households have no choice of heating system, and what is their profile?This work sets out to answer these questions empirically using discrete choice models. It starts by analyzing the technical, socio-demographic and spatial constraints that face households and create barriers to domestic energy choices. A method to detect household constraint is devised and applied to the choice of space heating system in 2006 and 2013. The second stage analyzes household preferences for heating equipment and retrofits. This second part is based on a discrete choice experiment specially carried out for this research among 2,000 households. This work sheds light on households’ preferences and heterogeneity, as well as their willingness to pay, the implicit discount rate and other economic impacts. Les préférences des ménages français pour les travaux de rénovation énergétique dans le logement ont été peu étudiées jusqu’à présent. Or, elles sont la clé d’une politique énergétique efficace et réaliste pour le secteur résidentiel, tant au niveau des aides proposées, qu’au niveau des objectifs à réaliser. Les ménages sont-ils intéressés par des travaux à fort potentiel d’économie d’énergie ? Combien sont-ils prêt à payer et est-ce que c’est suffisant pour couvrir les coûts réels ? Combien de ménages n’ont pas le choix de leur mode de chauffage et quel est leur profil ?La thèse s'attache à répondre à ces questions de façon empirique à l’aide de modèles de choix discrets. Il s’agit, dans un premier temps, d’analyser les contraintes techniques, sociodémographiques et spatiales que rencontrent les ménages et qui entravent les choix énergétiques dans le logement. Une méthodologie de détection des ménages contraints a été proposée, puis appliquée au choix du chauffage en 2006 et 2013. Dans un deuxième temps, les préférences des ménages pour les équipements de chauffage et les travaux de rénovation ont été analysées. Cette deuxième partie utilise une enquête expérimentale qui a été réalisée spécialement pour ce travail de recherche auprès de 2000 ménages. Ce travail a permis de comprendre les préférences des ménages, leur hétérogénéité, et d’en déduire les consentements à payer, les taux d’actualisation implicites et les différents effets économiques.

As part of Work Package 3 (WP3) in the FULFILL project, we collected quantitative data from six countries: Denmark, France, Germany, Italy, Latvia, and India. In the first round of the survey, we recruited a representative sample of approximately 2000 households in each country, taking into account both the individual and household perspectives. The survey includes a quantitative assessment of the carbon footprint in various domains of life, such as housing, mobility, and diet. In addition to this, the survey also measures socio-economic factors such as age, gender, income, education, household size, life stage, and political orientation. Furthermore, the survey includes measures of quality of life, encompassing aspects such as health and well-being, environmental quality, financial security, and comfort.

Le protocole mis en place pour cette méthode implique l'utilisation de huit complexes "sondes", obtenus par des opérations de symétrie à partir de l'état de transition de la réaction de transfert d'un atome d'hydrogène entre le nicotinamide et la lumiflavine. Ces complexes sont positionnés dans le site actif avec le groupe prosthétique comme référence et dans chaque cas l'énergie d'interaction protéine-ligand est évaluée par la fonction de score implémentée dans le logiciel de docking utilisé (AutoDock). L'énergie d'interaction la plus favorable permet d'identifier la face du groupe prosthétique accessible pour la réaction enzymatique dans le site actif. La méthode PredFace a été validée par l'analyse de l'ensemble des structures de la Protein Data Bank contenant des groupes prosthétiques de la famille des flavines (2170). Le protocole mis au point est très rapide (moins d'une minute), ce qui nous a permis de développer un site web afin de mettre cette méthode à la disposition de la communauté.La seconde méthode, ProsthDock, est une nouvelle méthode de docking basée sur le mécanisme d'une réaction enzymatique catalysée par un groupe prosthétique et guidée par la présence de ce groupe prosthétique dans le site actif de l'enzyme. Le développement de cette méthode a été motivé par le fait que les méthodes actuelles de docking, en présence de groupes prosthétiques, se révèlent incapables de produire des poses correctes pour des substrats, en accord avec les réactions enzymatiques. Afin de remédier à ce problème nous avons ajouté à la fonction de score classique un terme supplémentaire, qui rendra compte de l'interaction du ligand avec le groupe prosthétique. Dans un premier temps, nous avons construit un modèle simplifié du complexe NADH/FMN et calculé l'état de transition de la réaction de transfert d'hydrogène entre les deux partenaires. Des surfaces d'énergie potentielle pour cette réaction ont été calculées en variant la distance, l'angle et l'angle dièdre entre les deux réactifs. Un docking sous contrainte est ensuite réalisé et en fonction du positionnement de chaque pose de docking dans le site actif le terme supplémentaire de la fonction de score est calculé à partir des surfaces d'énergie potentielle, ce qui nous permet de modifier le classement des résultats de docking en favorisant les poses qui sont en accord avec la réaction enzymatique. During this PhD thesis we developped two new molecular modeling methods applied to enzymes containing flavin-type prosthetic groups.The first method, PredFace, predicts the stereochemistry of products from a reaction catalyzed by enzymes containing prosthetic groups, by automatically identifying the solvent-exposed face of the prosthetic group. The protocol involves the use of eigth complexes as "probes", obtained by symmetry operations starting from the transition state of a hydrogen atom transfer reaction between nicotinamide and lumiflavin. These complexes are positioned in the binding site with the prosthetic group as reference and the energy of the protein-ligand interaction is evaluated by the scoring function implemented in the docking software (AutoDock). The most favorable interaction energy allows the identification of the prosthetic group face that is available for the enzymatic reaction in the binding site. The PredFace method has been validated by analyzing all the structures in the Protein Data Bank containing flavin-derived prosthetic groups (2170). This method is very fast (less than a minute), which allowed us to develop a web site open to the scientific community.The second method, ProsthDock, is a new mechanism-based molecular docking method guided by prosthetic groups present in the active sites of enzymes. The development of this method was motivated by the incapacity of the currently available docking methods to provide, in the presence of prosthetic groups, ligand conformations that are compatible with the enzymatic reactions. In this regard, we have added a new term to the classical scoring function, to take into account the interaction between ligand and prosthetic group. We have built a simplified model of the NADH/FMN complex and calculated the transition state of the hydrogen transfer reaction between the two partners. Potential energy surfaces have been calculated for this reaction by variating the angle, diedral angle and distance between the two reaction partners. A subsequent docking with constraints provides binding site conformations of the ligand for which the new term of the scoring function is calculated using the potential energy surfaces. This results in a new ranking of the docking poses, favoring those in agreement with the enzymatic reaction.

For this reason, an accurate physical and perceptual prediction of wind turbine noise is of crucial importance for the design and deployment of modern horizontal-axis wind turbines. In the present work, we discuss a novel methodology for the far-field propagation and auralization of wind turbine noise in complex rural environments. First, the sound sources are modelled analytically using a RANS-based Amiet’s theory, accounting for leading- and trailing-edge noise. Secondly, a geometrical ray-tracing solver is used to compute the multiple source-receiver paths and evaluate the directivity gain. The pressure time signal of the equivalent source is then reconstructed using spectral shaping synthesis. Finally, the Harmonoise ray-based method is used to apply the noise attenuation due to atmospheric absorption, ground barriers, ground effects, and meteorological conditions. Also, the varying propagation delay of each source-receiver path is implemented in the time domain using appropriate interpolation techniques. The obtained audio signals are evaluated for different listener locations and operating conditions of the wind turbine.

L’influence écologique de l’apport de nutriments associé à la redistribution des sols pourrait être significative dans les environnements oligotrophes. On connaît très mal l’évolution des sols ennoyés au fond des retenues. Des observations préliminaires effectuées sur la retenue de Sarrans montrent que les sols conservent leur structure d’origine. Elles suggèrent aussi que des sols bruns de prairie, ennoyés en permanence depuis 80 ans, ou exondés occasionnellement, ont perdu 30 % de leur carbone, par minéralisation.[br/] - Dynamique à long terme : A long terme, ce sont les sols du bassin versant et de la zone de marnage en pente faible qui influencent l’écologie des retenues. Les sols du bassin versant dans la mesure où le contexte écologique influence l’érosion et l’apport de nutriments. Les sols de la zone littorale dans la mesure où ils soutiennent une production végétale, qui peut contribuer à filtrer l’eau, mais aussi à l’alimenter en carbone organique minéralisable.

Reservoir establishment results in the submersion of soils and vegetation. Their ecological evolution follows 3 main phases.[br/] - Initial: carbon and nutrients stored in living and dead vegetation biomass supply for a rise of the trophic level and productivity of the lake. During this phase, named « trophic upsurge », which duration and intensity are variable, water anoxia, CO2 and CH4 emissions also rise especially when temperature is high.[br/] - Mean Term: Water level fluctuates according to seasonal energy needs. Waves erode submerged soils along the shoreline. If the slope is steeper than 5%, soils are redistributed downslope and this flux contributes to the trophic upsurge and to sediment accumulation. These phenomena have been poorly studied and quantified. Our measurements at Sarrans reservoir suggest that soil redistribution is a major contributor to sediment accumulation. The ecological influence of carbon and nutrient inputs to the lake may be significant in oligotrophic environments. The evolution of permanently submerged soils is poorly known. Preliminary measurements at Sarrans reservoirs show that grassland cambisols (almost) permanently submerged have lost 30% of their original carbon store since impoundment.[br/] - On the long term, both catchment soils, through erosion and nutrient supply, and soils of the littoral zone, which support vegetation communities, influence reservoir ecology. The accumulation of sedimentary carbon in reservoirs appears much higher than in natural lakes, even eutrophic, and reasons for this are many. Greenhouse gas emission is also higher, because of higher sedimentation rate and increased water level fluctuations that favour methane bubbling and water degassing at the turbine outlet.

Elle commence à se développer au début des années 1990 sous l’impulsion de Dale Jamieson (1992) et de ses réflexions sur l’inadéquation entre notre système de valeurs et les problèmes environnementaux globaux ainsi que sous l’impulsion de Henry Shue (1993) et de sa distinction entre émissions de subsistance et émissions de luxe.

Le changement climatique exige une compréhension de son fonctionnement pour bâtir des politiques de gestion efficaces, car la variabilité climatique contemporaine a engendré des bouleversements des écosystèmes naturels et produit une désarticulation sociale. Il est donc nécessaire de revisiter certains concepts clés (dégradation, ressources naturelles, acteurs, etc.), avant d'examiner la réalité de la dégradation environnementale, au regard de facteurs peu souhaitables par rapport auxquels il faut pourtant essayer d'esquisser un futur désirable. Les dynamiques environnementales en cours génèrent, en effet, des mutations peu avantageuses et conduisent à des conflits redoutables sur l'eau, la terre et toutes les autres ressources dites naturelles. Dès lors, de nombreux défis se font jour ; ils appellent des solutions qui tiennent compte à la fois de l'illusion et du forçage du destin, car les expériences douloureuses imposent la prudence, mais les potentialités indiscutables fondent, a contrario, de réelles ambitions de sortie des situations difficiles dans lesquelles se trouve l'Afrique. Il s'agit d'un pari sur l'avenir, pour le continent, en tablant d'abord, sur une triple durabilité (institutionnelle, socio-économique et environnementale) mais aussi, sur sa capacité à s'adapter à l'adversité du changement climatique et à améliorer l'utilisation peu efficiente de ses ressources naturelles par une option claire et holistique pour les stratégies d'intégration régionale. C'est le miracle que l'Afrique se doit de faire dès à présent, et pendant ce siècle ! Mots clés : environnement, dégradation, changement climatique, ressources naturelles, acteurs.

Les bilans d'eau et d'énergie à la surface des continents y sont calculés à l'aide de modèle de surface continentale (Land Surface Model, LSM). Ces dernières années, l'intérêt d'utiliser un LSM sophistiqué pour modéliser le climat terrestre s'est affirmé, notamment au niveau des régions tempérées qui abritent des zones de transition où l'évapotranspiration est limitée d'une part par l'énergie d'autre part par l'eau disponible. Le site instrumenté du SIRTA mesure de nombreuses variables atmosphériques permettant de valider un modèle climatique en un point. Le SIRTA dispose également de données d'humidité du sol utilisées pour la première fois dans cette thèse. Ces données révèlent la présence d'une nappe perchée, en accord avec une campagne de mesures géophysiques réalisée durant cette thèse. Les données du SIRTA sont confrontées à des simulations régionales qui sont réalisées à l'aide du LSM ORCHIDEE couplé à un modèle atmosphérique. Nous développons la possibilité d'imposer une nappe au sein du sol modélisé par ORCHIDEE, ce qui permet de soutenir l'évaporation en été au SIRTA, en accord avec les observations. Nous explorons différentes hypothèses hydrologiques qui entrainent une augmentation de l'évaporation à l'échelle de l'Europe de l'Ouest et impliquent une augmentation des précipitations ainsi qu'un refroidissement de l'air. Ces hypothèses sont également testées lors de simulations globales afin d'en étudier l'influence sur les caractéristiques du climat et du changement climatique causé par une augmentation de gaz à effet de serre. General Circulation Models (GCM) are tools which allow studying climate at large scale. Water and energy budget over continental surface are calculated by Land Surface Model (LSM). Interest on using a sophistical LSM to simulate earth climate grew up last years, in particular in transition area, where evaporation is limited on one side by energy and on other side by available water. The instrumented site of SIRTA observes many atmospheric variables and allows validating a climate model on one point. The SIRTA have also soil moisture data which are used for the first time in this thesis. These data reveal a shallow water table, according to geophysical campaign conducted during this thesis. Data from SIRTA are confronted to regional simulations produced with the LSM ORCHIDEE coupled to an atmospheric model. We develop the possibility to impose a water table in the soil modeled by ORCHIDEE, which allows maintaining evaporation during summer at the SIRTA, according to observations. We explore different hydrologic hypothesis which conduct to an evaporation increase at Western European scale and also involve precipitation increase and air cooling. Theses hypothesis are also tested in global simulations to study effects on climate and on climate change due to an increase of greenhouse gases.
