description Publicationkeyboard_double_arrow_right Article 2017Publisher:Romanian Foundation for Business Intelligence Authors: Viorel POP;Energy is an essential factor regarding the economic development and for providing a high standard of living to the population of any country. Because energy is produced mainly using classic fuels (coal, oil and gas) for a few decades there are signals regarding their exhaustion. Therefore, mankind should concern more about finding viable alternatives to replace the classical fuels. This way the use of nuclear fuels appeared, then the force of the wind, of the tides and of the photovoltaic cells. However, there are still enough energy resources for further growth of the global energy production. The great consumers are both the major energy producers, only their hierarchy has changed and changes over time. The paper presents all these countries, and also Romania, including its specific developments in recent years.

Available estimates of the induced land use changes conclude that this policy is inefficient to reduce emissions of GreenHouse Gas. We show that the crop yield evolutions in these estimates are significantly lower than the observed and expected evolutions. This difference is directly related to biased calibration choice of behavioral parameters. We show using the GTAP-BIO framework that a consistent calibration of these parameters leads to a strong reduction (by around 80% in the long run) of the land use changes and induced emissions.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis 2010 BelgiumPublisher:Universite Libre de Bruxelles Authors: Kestemont, Bruno;Existe-t-il un consensus scientifique sur les conditions de la durabilité ?Est-il possible de construire un indicateur unique de soutenabilité faible ?Quelles sont les composantes objectives et subjectives des indicateurs ?Peut-on envisager des indicateurs objectifs de soutenabilité ?Quelles voies de recherche sont-elles nécessaires pour développer des indicateurs de développement durable ?Telles sont les questions auxquelles cet ouvrage tente de répondre.La comparaison des courants de la soutenabilité faible et de la soutenabilité forte nous sert de fil conducteur pour évaluer la part normative et la part objective du choix des paramètres et de leur méthode d'agrégation. L'agrégation arithmétique implique des hypothèses de substituabilité entre les facteurs, ce qui relève de la soutenabilité faible. La pondération, toujours normative, peut être explicite ou se traduire par le choix d'une unité ou dimension unique. Nous redéfinissons la soutenabilité faible comme étant la réduction de la complexité à une dimension unique. Il y a dès lors autant d'indicateurs de soutenabilité faible que de choix possibles de cette dimension unique. En particulier, l'empreinte écologique par habitant relève d'une forme "écologique" de soutenabilité faible. Le prix de marché est l'unité fondamentale de mesure de sa forme "économique". Nous montrons que les acteurs ne savent pas bien identifier leur intérêt et qu'ils ne sont pas parfaitement égoïstes, ce qui introduit un biais non systématique remarquable dans toute mesure en unité monétaire. La soutenabilité forte se caractérise par la multiplicité de dimensions ou "capitaux critiques" dont le dépassement d'un seul suffit à déterminer la non soutenabilité. Les différentes formes de soutenabilités faibles peuvent représenter des capitaux critiques parmi d'autres.Nous présentons une typologie des acteurs et du partage des responsabilités, également susceptible d'introduire des grandes divergences dans les résultats publiés. Quelques études de cas illustrent ces différents éléments dans des contextes contrastés. L'empreinte écologique de consommation se limite en particulier à une responsabilisation du seul consommateur, alors que les comptes nationaux permettent d'envisager la coresponsabilité de l'ensemble des acteurs. L'indicateur de "dématérialisation de l'économie" appliqué à un village indien montre la pertinence de mesurer l'utilisation absolue de matière sans pondération monétaire. Il est par ailleurs possible de minimiser le coût de dépollution sans toucher à la limite absolue d'émissions globales de centrales thermiques. Les deux dimensions, coûts sociaux et bénéfices environnementaux, peuvent donc être traitées séparément.En conclusion, il est possible d'identifier, dans chaque calcul d'indicateur de développement durable, une composante relativement objective de soutenabilité "forte" et une composante "faible", négociable, de partage des droits et responsabilités./ We study how different world views may influence how to develop sustainable development indicators. The comparison of weak sustainability and strong sustainability serves as a guide to estimate the share of objective versus normative choice of parameters and their method of aggregation. We then present a typology of actors and shared responsibilities, which may also introduce large discrepancies in the results published. Some case studies illustrate these different elements in contrasting contexts. It appears that it is possible to identify in each calculation of sustainable development indicator, a relatively objective component of sustainability and a negotiable component of shared rights and responsibilities. info:eu-repo/semantics/nonPublished Doctorat en Sciences

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Other literature type 2009 FrancePublisher:Ecole Centrale de Nantes Authors: Saulnier, Jean Baptiste;This work focuses on the refinement of sea-states spectral characterisation in the frame of the development of wave energy converters (WECs). Until now, this characterisation has been limited to the consideration of basic global parameters such as the significant wave height and mean wave period. The present work namely underlines - thanks to simplified numerical models - that such a description is not sufficient to account for the performance of WECs, for they still exhibit a large variability in terms of mean production while wave energy and period are fixed. It is therefore needed to refine this description by introducing new wave characteristics, such as the wave groupiness, which is itself related to the sea-state's spectral bandwidth. The classical - spectral - approaches, allowing a statistical analysis of wave groups along with other works in the literature, permit to draw a set of relevant spectral parameters. The sensitivity of simplified offshore WEC models (linear in the frequency domain) to these parameters is then observed. The question of deterministic mean power estimation - namely in the case of non-linear models - is also raised, for it is also related somehow to the bandwidth of the wave field. A sea-state is actually made of a superimposition of various wave systems (as swells and wind-sea). It is then possible to refine even more its description, namely through the multi-system approach. The latter enables indeed to track in time and space the wave systems independently of each other. An algorithm for the automatic spatiotemporal analysis is proposed and illustrated to this end. Lastly, the influence of such description refinements (wave groupiness and multi-system approach) is observed at several locations (Portugal, North Sea, California) by considering various WEC models (linear axi-symmetric heaving devices, 3D SEAREV with non-linear hydrodynamics): in all cases, it is shown that both extended descriptions allow for a better characterisation of the mean WEC performance at both short and long term. Ces travaux portent sur la caractérisation spectrale des états de mer dans le cadre du développement de systèmes récupérateurs de l'énergie des vagues (SREVs). Jusqu'alors, cette caractérisation s'est limitée à des paramètres globaux basiques tels que la hauteur significative et la période moyenne des vagues. Les présents travaux soulignent notamment, à l'aide de modèles simplifiés, que cette description est insuffisante car un SREV montre encore une grande variabilité en termes de production moyenne, ces deux paramètres étant fixés par ailleurs. On s'intéresse donc à raffiner cette description en considérant des caractéristiques de vagues nouvelles, comme le groupement de vagues, lui-même lié à la largeur de bande de l'état de mer. Les approches classiques - spectrales - sur l'étude descriptive des groupes de vagues et la littérature permettent de dégager un certain nombre de paramètres spectraux. On observe ensuite la sensibilité de modèles de SREVs offshore simplifiés (modèles fréquentiels linéaires) à ces paramètres de largeur globale. La question de l'estimation déterministe de performance moyenne (dans le cas de convertisseurs non-linéaires) est également abordée, étant elle-même liée à cette caractéristique. Un état de mer étant constitué de plusieurs systèmes de vagues (houles, mer de vent), il est encore possible de raffiner sa description grâce à une approche multisystème. Celle-ci permet en outre de suivre ces systèmes indépendamment dans le temps et l'espace. Un algorithme d'analyse spatio-temporelle est proposé et illustré à cet égard. Enfin, l'influence de ces raffinements est observée en différents sites (Portugal, Mer du Nord, Californie) sur des cas de SREVs divers (systèmes axi-symétriques linéaires, SEAREV 3D d'hydrodynamique non-linéaire), et montre que dans tous les cas, le raffinement apporté permet de mieux caractériser la production à court et long terme de ces dispositifs.

This would likely affect the relative competitive position of Quebec in North America. Using the Delphi technique and partial budgets, climate change scenarios for the 2050 period were elaborated and their impact on relative competitiveness assessed for Quebec and its competitors in North America. Results indicate that Quebec competitive position would improve due to more favorable conditions for corn and apple production and due to worsen conditions for the competitors in maple syrup production.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis , Other literature type 2015 SwitzerlandPublisher:Lausanne, EPFL Authors: Munafò, Sébastien;This thesis aims to examine the causal mechanisms of living environments on leisure mobilities and verify whether their inclusion is actually able to challenge the compact city as a sustainable urban form. The research focuses on the Swiss case and in particular the cities of Geneva and Zurich. The empirical approach is based on three types of additional analysis carried out in these areas: contextual analysis, quantitative analyzes based on data from the Mobility and Transport Microcensus 2010 and qualitative analysis through interviews. The main results are the following: â ¢ We find the existence of two opposing logics of association between land density and distance traveled: a decreasing link to daily mobility, but a positive correlation for occasional mobility (day trips and overnight trips). The denser is the living environment, the greater is the distance for this mobility. â ¢ Adding the two types of mobility to obtain a total average, we find that the inner city dwellers displayed, ultimately, much higher totals than would suggest the analysis of their daily mobility alone which therefore represent an invitation to invalidate the link compact city=short distances. â ¢ By transforming these distances into environmental impact, however, our calculations show that even while taking into account the many trips of urban dwellers, the negative relationship between total energy consumption and land density of the territory remains. â ¢ By examining in detail the share of leisure in daily and occasional mobility, we see that the logic of compensation is not what structures the links with urban environnements. In everyday life, the logic of proximity prevails: to live in the centre is rather correlated to more compactophile leisure and residing in the periphery to more leisure oriented towards the attributes of nature. â ¢ For occasional trips, we show firstly that compactophile mobilities represent a large part of these practices among all respondents, and secondly, that even in the case of very important and high energy consuming naturophile mobility, the relationship with the density of the living environment is not established. The central Genevans and are much less consumers of this type of leisure than people in the centre of Zurich even though their city is much more airy and green. Moreover, we also highlight, in peri-urban dwellers, a very intense mobility or this purpose. â ¢ The interpretation that we propose refers to lifestyles and residential choice of city dwellers which takes into account their leisure aspirations. These tastes are then translated into specific leisure activities and travel. In everyday life, they rely on proximity and functional, social and sensitive attributes of their living environment that they have chosen largely also for this. When it comes to breaking the routines during holidays and vacations, the same lifestyles result in significant occasional mobility whose motives can register in continuity of their daily lifestyle (loving the same things elsewhere) or by contrast (appreciate the diversity of spaces). In both cases, these motivations echo the valorisation of the diversity inherent in urbanity without questioning the urban residential location quality itself. Our results lead us ultimately to reject the compensation effect hypothesis and reaffirm, against the defenders of the sprawl-city, the virtues of the compact city, which remains a sustainable urban form, including for our leisure mobility.

In the western cotton growing area of Burkina Faso, the variability and the diversity of the income levels of family farms (EAFs) mean that these farms require suitable agronomic accompaniment. Objectives. This article gives an account of this diversity and the need for accompaniment according to the type of identified EAF.Method. The data were collected by the active method of participative research and by investigation of the practices of 120 farms in the commune of Koumbia. Principal component analyses with economic indicators of the EAF were applied, followed by an ascending hierarchical clustering. The structural characteristics, the agro-pastoral practices of production, and the perceptions of the EAF regarding the constraints and appropriateness of agricultural production were compared by variance analysis. Results. The results showed three types of farm: farms with a low-income culture (farmers with few animals), those with a high income culture (farmers with a large number of animals) and those deriving income from breeding (stockbreeders). Taking into account the structure of the farms, their production practices, their technico-economic performance and their appropriateness of agricultural production, the form of sustainable accompaniment needed may be identified in relation to several common or specific innovations of the identified farm types. Accompaniments in the case of farm stock management, and good practice in the management of soil fertility and of animals were common to the three types of EAF. The fodder culture, fattening on pasture and the method of dairy production were specific to the farmers with a large number of animals and to the stockbreeders. The improvement of the food value of culture residues and of some aspects of the maintenance of oxen were more appropriate to the farmers with few animals. Conclusions. In order to succeed, the process of accompaniment must take into account both these specificities and the concept of sustainability. Description du sujet. Dans la zone cotonnière ouest du Burkina Faso, la variabilité et la diversité des revenus des exploitations agricoles familiales (EAF) demandent pour ces dernières des accompagnements appropriés. Objectifs. Cet article rend compte de cette diversité et des besoins d’accompagnement selon les types d’EAF identifiés.Méthode. Les données ont été collectées par la méthode active de recherche participative et par enquête auprès d’un échantillon raisonné de 120 exploitations dans la commune de Koumbia. Une analyse en composante principale avec des indicateurs économiques de l’EAF suivie d’une classification ascendante hiérarchique ont été appliquées. Les caractéristiques structurelles, les pratiques de production agro-pastorales, les perceptions des chefs d’EAF sur les contraintes et opportunités de production agropastorale ont été comparées par une analyse de variance.Résultats. Les résultats montrent trois types d’exploitations : les exploitations à faible revenu culture (agriculteurs), à fort revenu culture (agro-éleveurs) et à revenu élevage (éleveurs). À la lumière de leurs structures, pratiques de production, performances technico-économiques et opportunités de production agricole, leur accompagnement peut porter sur plusieurs innovations durables communes ou spécifiques des types identifiés. Des accompagnements sur la gestion des ressources de l’exploitation, les bonnes pratiques de gestion de la fertilité des sols et des animaux sont communs aux trois types d’EAF. Les cultures fourragères, l’embouche et la production laitière sont spécifiques aux agro-éleveurs et éleveurs. L’amélioration de la valeur nutritive des résidus de cultures et l’entretien des bœufs de trait conviennent plus aux agriculteurs.Conclusions. Pour réussir, le processus d’accompagnement doit prendre en compte ces spécificités et la notion de durabilité.

J.;Metadata only record This document presents an analysis of Fulani pastoral farming systems that focuses on how pastoralists use silvopastoral land. It aims to provide the missing knowledge needed to implement the resource management ('gestion des terroirs') approach at village level. In this region the influence of pastoral land use on the environment appears to be less pronounced than that of crop cultivation, even though levels of animal production are reasonable. The carrying capacity of the region has not yet been attained. Current constraints to pastoral land use in the region arise from the encroachment of cropland at the expense of pastoral land, and the increase in animal numbers. To develop sustainable natural resource management at village level that includes Fulani pastoral land use, the key factors appear to be the integration of livestock husbandry and cropland cultivation at household level, agreements between pastoralists and cropland farmers on land tenure and resource management, and support targeting of Fulani households (which have so far been neglected). Specific recommendations are given. (CAB Abstract)

D'abord, il s'agit de vérifier la qualité de ses travaux de recherche scientifique menés dans des contextes et avec des responsabilités variés en suivant la grille d'analyse de référence d'un doctorat. Ensuite, l'analyse consiste à prendre un recul critique sur les bilans de réalisations majeures (Antilles, Guyane…) en mobilisant l'approche de M. Callon dont la théorie de la traduction permet de construire le réseau des acteurs et de le projeter dans la problématique. Cette grille d'analyse est complétée par l'étude des aspects de temporalité, légitimité et d'acceptabilité pour chaque réalisation. Ce travail sur diverses situations d'intervention permet de préparer une réflexion sur la proposition méthodologique qui suit et son adaptation à des conditions variables. Enfin, les connaissances acquises sont synthétisées afin de construire une méthode de prospective qui permettrait de gagner en temps, en efficacité et en moyens sur des projets à venir. Pour cela, l'analyse s'appuie sur la vision de R. Passet, qui structure les éléments de tout projet dans la hiérarchie des composantes de la durabilité. Le système dynamique qui en résulte peut être alors croisé avec divers scénarios afin d'en simuler les conséquences et donc d‟éclairer les choix. Cette méthode, dite Aster, est testée sur le cas « modèle » et bien documenté de l'élevage de la crevette Macrobrachium rosenbergii en Guyane française. Elle permet d'aboutir à des recommandations précises et argumentées en matière de recherche comme de développement pour tout décideur impliqué. Aquaculture is one of the main supply of protein in feed for mankind, notably in Asia. It increases and had exceeded the level of production of world fisheries, which is decreasing. According to sites and rearing methods, aquaculture contributes to add value but also in some cases to impact negatively the aquatic ecosystems. In the coastal area, a rich and productive zone, but also a place of conflicts, this activity presents a high potential for development if it takes into account the rules of sustainability. The conditions of this sustainability may be cleared with appropriate methods of foresight analysis applied for each development project. The analysis of the professional experience of D. Lacroix for 33 years in aquaculture is structured in three steps. Firstly, the work is to check the scientific value of the research conducted under his responsibility in various contexts and for different responsibilities. This study refers to the requirements of a PhD. In the second part of the work, the results of few major projects (French West Indies, French Guyana….) are analysed with the support of the theory of translation (Callon et al) which allows to build a network of actors and to project it into the context. This way of study includes a special attention to the aspects of time planning, legitimacy and acceptability. Finally, the author examines how this knowledge gained from experience could help building a method for foresight analysis aiming at a shorter planning, a better timing and less means for future projects. To achieve this goal the author integrates the vision of the economist R. Passet which structures any project in an ecosystemic framework, including criteria of sustainability. The mix of these two approaches (Callon & Passet) entails in a new tool for foresight analysis, called Aster, which originality is to offer the possibility to test various scenarios and related consequences to help decision -makers. This new method of foresight analysis, is then tested on the well known case study of the development of prawn Macrobrachium rosenbergii in French Guyana. The test shows to be successful as it delivers precise and arguable recommendations about research and development for all stakeholders.

Therefore aquaculture development is subdued to institutional context which defines the rules for use and conservation of the environment. This paper analyses the impact of marine environment regulations on economic operating of aquaculture enterprises and on industrial dynamics. Because aquaculture enterprises use a collective good, an economic approach of aquaculture has to take into account not only the relations between enterprises and environment, but also the relations between the enterprises themselves, through production externalities. In this study, several economic tools are considered in order to incite enterprises to integrate pad of the cost of their effects on the environment. But these public policies have to take into account the youth of the activity, the specific economic situation of the enterprises and the place of aquaculture in global coastal management. [NOT CONTROLLED OCR] L'aquaculture est confrontée à un cadre institutionnel définissant les conditions d'accès d'utilisation et de protection du milieu marin. La réglementation sur l'environnement va avoir un impact sur le fonctionnement économique des entreprises et sur la dynamique sectorielle de l'aquaculture. A partir de l'étude de la nature des relations entre entreprises et milieu, on peut proposer un certain nombre d'outils économiques permettant de faire prendre en compte par les entreprises une partie du coût de leurs effets sur l'environnement. Dans le cas particulier de l'aquaculture marine, cette réglementation doit cependant tenir compte de la jeunesse de l'activité, de la situation économique des entreprises et de leur rôle dans une politique d'aménagement du littoral.

description Publicationkeyboard_double_arrow_right Article 2017Publisher:Romanian Foundation for Business Intelligence Authors: Viorel POP;Energy is an essential factor regarding the economic development and for providing a high standard of living to the population of any country. Because energy is produced mainly using classic fuels (coal, oil and gas) for a few decades there are signals regarding their exhaustion. Therefore, mankind should concern more about finding viable alternatives to replace the classical fuels. This way the use of nuclear fuels appeared, then the force of the wind, of the tides and of the photovoltaic cells. However, there are still enough energy resources for further growth of the global energy production. The great consumers are both the major energy producers, only their hierarchy has changed and changes over time. The paper presents all these countries, and also Romania, including its specific developments in recent years.

Available estimates of the induced land use changes conclude that this policy is inefficient to reduce emissions of GreenHouse Gas. We show that the crop yield evolutions in these estimates are significantly lower than the observed and expected evolutions. This difference is directly related to biased calibration choice of behavioral parameters. We show using the GTAP-BIO framework that a consistent calibration of these parameters leads to a strong reduction (by around 80% in the long run) of the land use changes and induced emissions.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis 2010 BelgiumPublisher:Universite Libre de Bruxelles Authors: Kestemont, Bruno;Existe-t-il un consensus scientifique sur les conditions de la durabilité ?Est-il possible de construire un indicateur unique de soutenabilité faible ?Quelles sont les composantes objectives et subjectives des indicateurs ?Peut-on envisager des indicateurs objectifs de soutenabilité ?Quelles voies de recherche sont-elles nécessaires pour développer des indicateurs de développement durable ?Telles sont les questions auxquelles cet ouvrage tente de répondre.La comparaison des courants de la soutenabilité faible et de la soutenabilité forte nous sert de fil conducteur pour évaluer la part normative et la part objective du choix des paramètres et de leur méthode d'agrégation. L'agrégation arithmétique implique des hypothèses de substituabilité entre les facteurs, ce qui relève de la soutenabilité faible. La pondération, toujours normative, peut être explicite ou se traduire par le choix d'une unité ou dimension unique. Nous redéfinissons la soutenabilité faible comme étant la réduction de la complexité à une dimension unique. Il y a dès lors autant d'indicateurs de soutenabilité faible que de choix possibles de cette dimension unique. En particulier, l'empreinte écologique par habitant relève d'une forme "écologique" de soutenabilité faible. Le prix de marché est l'unité fondamentale de mesure de sa forme "économique". Nous montrons que les acteurs ne savent pas bien identifier leur intérêt et qu'ils ne sont pas parfaitement égoïstes, ce qui introduit un biais non systématique remarquable dans toute mesure en unité monétaire. La soutenabilité forte se caractérise par la multiplicité de dimensions ou "capitaux critiques" dont le dépassement d'un seul suffit à déterminer la non soutenabilité. Les différentes formes de soutenabilités faibles peuvent représenter des capitaux critiques parmi d'autres.Nous présentons une typologie des acteurs et du partage des responsabilités, également susceptible d'introduire des grandes divergences dans les résultats publiés. Quelques études de cas illustrent ces différents éléments dans des contextes contrastés. L'empreinte écologique de consommation se limite en particulier à une responsabilisation du seul consommateur, alors que les comptes nationaux permettent d'envisager la coresponsabilité de l'ensemble des acteurs. L'indicateur de "dématérialisation de l'économie" appliqué à un village indien montre la pertinence de mesurer l'utilisation absolue de matière sans pondération monétaire. Il est par ailleurs possible de minimiser le coût de dépollution sans toucher à la limite absolue d'émissions globales de centrales thermiques. Les deux dimensions, coûts sociaux et bénéfices environnementaux, peuvent donc être traitées séparément.En conclusion, il est possible d'identifier, dans chaque calcul d'indicateur de développement durable, une composante relativement objective de soutenabilité "forte" et une composante "faible", négociable, de partage des droits et responsabilités./ We study how different world views may influence how to develop sustainable development indicators. The comparison of weak sustainability and strong sustainability serves as a guide to estimate the share of objective versus normative choice of parameters and their method of aggregation. We then present a typology of actors and shared responsibilities, which may also introduce large discrepancies in the results published. Some case studies illustrate these different elements in contrasting contexts. It appears that it is possible to identify in each calculation of sustainable development indicator, a relatively objective component of sustainability and a negotiable component of shared rights and responsibilities. info:eu-repo/semantics/nonPublished Doctorat en Sciences

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Other literature type 2009 FrancePublisher:Ecole Centrale de Nantes Authors: Saulnier, Jean Baptiste;This work focuses on the refinement of sea-states spectral characterisation in the frame of the development of wave energy converters (WECs). Until now, this characterisation has been limited to the consideration of basic global parameters such as the significant wave height and mean wave period. The present work namely underlines - thanks to simplified numerical models - that such a description is not sufficient to account for the performance of WECs, for they still exhibit a large variability in terms of mean production while wave energy and period are fixed. It is therefore needed to refine this description by introducing new wave characteristics, such as the wave groupiness, which is itself related to the sea-state's spectral bandwidth. The classical - spectral - approaches, allowing a statistical analysis of wave groups along with other works in the literature, permit to draw a set of relevant spectral parameters. The sensitivity of simplified offshore WEC models (linear in the frequency domain) to these parameters is then observed. The question of deterministic mean power estimation - namely in the case of non-linear models - is also raised, for it is also related somehow to the bandwidth of the wave field. A sea-state is actually made of a superimposition of various wave systems (as swells and wind-sea). It is then possible to refine even more its description, namely through the multi-system approach. The latter enables indeed to track in time and space the wave systems independently of each other. An algorithm for the automatic spatiotemporal analysis is proposed and illustrated to this end. Lastly, the influence of such description refinements (wave groupiness and multi-system approach) is observed at several locations (Portugal, North Sea, California) by considering various WEC models (linear axi-symmetric heaving devices, 3D SEAREV with non-linear hydrodynamics): in all cases, it is shown that both extended descriptions allow for a better characterisation of the mean WEC performance at both short and long term. Ces travaux portent sur la caractérisation spectrale des états de mer dans le cadre du développement de systèmes récupérateurs de l'énergie des vagues (SREVs). Jusqu'alors, cette caractérisation s'est limitée à des paramètres globaux basiques tels que la hauteur significative et la période moyenne des vagues. Les présents travaux soulignent notamment, à l'aide de modèles simplifiés, que cette description est insuffisante car un SREV montre encore une grande variabilité en termes de production moyenne, ces deux paramètres étant fixés par ailleurs. On s'intéresse donc à raffiner cette description en considérant des caractéristiques de vagues nouvelles, comme le groupement de vagues, lui-même lié à la largeur de bande de l'état de mer. Les approches classiques - spectrales - sur l'étude descriptive des groupes de vagues et la littérature permettent de dégager un certain nombre de paramètres spectraux. On observe ensuite la sensibilité de modèles de SREVs offshore simplifiés (modèles fréquentiels linéaires) à ces paramètres de largeur globale. La question de l'estimation déterministe de performance moyenne (dans le cas de convertisseurs non-linéaires) est également abordée, étant elle-même liée à cette caractéristique. Un état de mer étant constitué de plusieurs systèmes de vagues (houles, mer de vent), il est encore possible de raffiner sa description grâce à une approche multisystème. Celle-ci permet en outre de suivre ces systèmes indépendamment dans le temps et l'espace. Un algorithme d'analyse spatio-temporelle est proposé et illustré à cet égard. Enfin, l'influence de ces raffinements est observée en différents sites (Portugal, Mer du Nord, Californie) sur des cas de SREVs divers (systèmes axi-symétriques linéaires, SEAREV 3D d'hydrodynamique non-linéaire), et montre que dans tous les cas, le raffinement apporté permet de mieux caractériser la production à court et long terme de ces dispositifs.

This would likely affect the relative competitive position of Quebec in North America. Using the Delphi technique and partial budgets, climate change scenarios for the 2050 period were elaborated and their impact on relative competitiveness assessed for Quebec and its competitors in North America. Results indicate that Quebec competitive position would improve due to more favorable conditions for corn and apple production and due to worsen conditions for the competitors in maple syrup production.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis , Other literature type 2015 SwitzerlandPublisher:Lausanne, EPFL Authors: Munafò, Sébastien;This thesis aims to examine the causal mechanisms of living environments on leisure mobilities and verify whether their inclusion is actually able to challenge the compact city as a sustainable urban form. The research focuses on the Swiss case and in particular the cities of Geneva and Zurich. The empirical approach is based on three types of additional analysis carried out in these areas: contextual analysis, quantitative analyzes based on data from the Mobility and Transport Microcensus 2010 and qualitative analysis through interviews. The main results are the following: â ¢ We find the existence of two opposing logics of association between land density and distance traveled: a decreasing link to daily mobility, but a positive correlation for occasional mobility (day trips and overnight trips). The denser is the living environment, the greater is the distance for this mobility. â ¢ Adding the two types of mobility to obtain a total average, we find that the inner city dwellers displayed, ultimately, much higher totals than would suggest the analysis of their daily mobility alone which therefore represent an invitation to invalidate the link compact city=short distances. â ¢ By transforming these distances into environmental impact, however, our calculations show that even while taking into account the many trips of urban dwellers, the negative relationship between total energy consumption and land density of the territory remains. â ¢ By examining in detail the share of leisure in daily and occasional mobility, we see that the logic of compensation is not what structures the links with urban environnements. In everyday life, the logic of proximity prevails: to live in the centre is rather correlated to more compactophile leisure and residing in the periphery to more leisure oriented towards the attributes of nature. â ¢ For occasional trips, we show firstly that compactophile mobilities represent a large part of these practices among all respondents, and secondly, that even in the case of very important and high energy consuming naturophile mobility, the relationship with the density of the living environment is not established. The central Genevans and are much less consumers of this type of leisure than people in the centre of Zurich even though their city is much more airy and green. Moreover, we also highlight, in peri-urban dwellers, a very intense mobility or this purpose. â ¢ The interpretation that we propose refers to lifestyles and residential choice of city dwellers which takes into account their leisure aspirations. These tastes are then translated into specific leisure activities and travel. In everyday life, they rely on proximity and functional, social and sensitive attributes of their living environment that they have chosen largely also for this. When it comes to breaking the routines during holidays and vacations, the same lifestyles result in significant occasional mobility whose motives can register in continuity of their daily lifestyle (loving the same things elsewhere) or by contrast (appreciate the diversity of spaces). In both cases, these motivations echo the valorisation of the diversity inherent in urbanity without questioning the urban residential location quality itself. Our results lead us ultimately to reject the compensation effect hypothesis and reaffirm, against the defenders of the sprawl-city, the virtues of the compact city, which remains a sustainable urban form, including for our leisure mobility.

In the western cotton growing area of Burkina Faso, the variability and the diversity of the income levels of family farms (EAFs) mean that these farms require suitable agronomic accompaniment. Objectives. This article gives an account of this diversity and the need for accompaniment according to the type of identified EAF.Method. The data were collected by the active method of participative research and by investigation of the practices of 120 farms in the commune of Koumbia. Principal component analyses with economic indicators of the EAF were applied, followed by an ascending hierarchical clustering. The structural characteristics, the agro-pastoral practices of production, and the perceptions of the EAF regarding the constraints and appropriateness of agricultural production were compared by variance analysis. Results. The results showed three types of farm: farms with a low-income culture (farmers with few animals), those with a high income culture (farmers with a large number of animals) and those deriving income from breeding (stockbreeders). Taking into account the structure of the farms, their production practices, their technico-economic performance and their appropriateness of agricultural production, the form of sustainable accompaniment needed may be identified in relation to several common or specific innovations of the identified farm types. Accompaniments in the case of farm stock management, and good practice in the management of soil fertility and of animals were common to the three types of EAF. The fodder culture, fattening on pasture and the method of dairy production were specific to the farmers with a large number of animals and to the stockbreeders. The improvement of the food value of culture residues and of some aspects of the maintenance of oxen were more appropriate to the farmers with few animals. Conclusions. In order to succeed, the process of accompaniment must take into account both these specificities and the concept of sustainability. Description du sujet. Dans la zone cotonnière ouest du Burkina Faso, la variabilité et la diversité des revenus des exploitations agricoles familiales (EAF) demandent pour ces dernières des accompagnements appropriés. Objectifs. Cet article rend compte de cette diversité et des besoins d’accompagnement selon les types d’EAF identifiés.Méthode. Les données ont été collectées par la méthode active de recherche participative et par enquête auprès d’un échantillon raisonné de 120 exploitations dans la commune de Koumbia. Une analyse en composante principale avec des indicateurs économiques de l’EAF suivie d’une classification ascendante hiérarchique ont été appliquées. Les caractéristiques structurelles, les pratiques de production agro-pastorales, les perceptions des chefs d’EAF sur les contraintes et opportunités de production agropastorale ont été comparées par une analyse de variance.Résultats. Les résultats montrent trois types d’exploitations : les exploitations à faible revenu culture (agriculteurs), à fort revenu culture (agro-éleveurs) et à revenu élevage (éleveurs). À la lumière de leurs structures, pratiques de production, performances technico-économiques et opportunités de production agricole, leur accompagnement peut porter sur plusieurs innovations durables communes ou spécifiques des types identifiés. Des accompagnements sur la gestion des ressources de l’exploitation, les bonnes pratiques de gestion de la fertilité des sols et des animaux sont communs aux trois types d’EAF. Les cultures fourragères, l’embouche et la production laitière sont spécifiques aux agro-éleveurs et éleveurs. L’amélioration de la valeur nutritive des résidus de cultures et l’entretien des bœufs de trait conviennent plus aux agriculteurs.Conclusions. Pour réussir, le processus d’accompagnement doit prendre en compte ces spécificités et la notion de durabilité.

J.;Metadata only record This document presents an analysis of Fulani pastoral farming systems that focuses on how pastoralists use silvopastoral land. It aims to provide the missing knowledge needed to implement the resource management ('gestion des terroirs') approach at village level. In this region the influence of pastoral land use on the environment appears to be less pronounced than that of crop cultivation, even though levels of animal production are reasonable. The carrying capacity of the region has not yet been attained. Current constraints to pastoral land use in the region arise from the encroachment of cropland at the expense of pastoral land, and the increase in animal numbers. To develop sustainable natural resource management at village level that includes Fulani pastoral land use, the key factors appear to be the integration of livestock husbandry and cropland cultivation at household level, agreements between pastoralists and cropland farmers on land tenure and resource management, and support targeting of Fulani households (which have so far been neglected). Specific recommendations are given. (CAB Abstract)

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Other literature type 2010 FrancePublisher:AgroParisTech, ABIES Authors: Lacroix, Denis;L'aquaculture est l'une des composantes principales de l'apport en protéines dans le monde, surtout en Asie. Elle croît, alors que la pêche, qu'elle a dépassée en tonnage comme en valeur, décline. Selon les écosystèmes et les méthodes employées, elle peut contribuer à valoriser, mais aussi à dégrader les milieux aquatiques. Dans la zone côtière, espace riche et productif au plan biologique mais convoité, l'aquaculture conserve un potentiel de développement si sa mise en œuvre intègre les principes de la durabilité. Celle-ci peut être éclairée par la prospective avec des méthodes d'analyse adaptées à chaque projet. L'analyse de l'expérience de 33 ans en aquaculture de D. Lacroix est faite en trois temps. D'abord, il s'agit de vérifier la qualité de ses travaux de recherche scientifique menés dans des contextes et avec des responsabilités variés en suivant la grille d'analyse de référence d'un doctorat. Ensuite, l'analyse consiste à prendre un recul critique sur les bilans de réalisations majeures (Antilles, Guyane…) en mobilisant l'approche de M. Callon dont la théorie de la traduction permet de construire le réseau des acteurs et de le projeter dans la problématique. Cette grille d'analyse est complétée par l'étude des aspects de temporalité, légitimité et d'acceptabilité pour chaque réalisation. Ce travail sur diverses situations d'intervention permet de préparer une réflexion sur la proposition méthodologique qui suit et son adaptation à des conditions variables. Enfin, les connaissances acquises sont synthétisées afin de construire une méthode de prospective qui permettrait de gagner en temps, en efficacité et en moyens sur des projets à venir. Pour cela, l'analyse s'appuie sur la vision de R. Passet, qui structure les éléments de tout projet dans la hiérarchie des composantes de la durabilité. Le système dynamique qui en résulte peut être alors croisé avec divers scénarios afin d'en simuler les conséquences et donc d‟éclairer les choix. Cette méthode, dite Aster, est testée sur le cas « modèle » et bien documenté de l'élevage de la crevette Macrobrachium rosenbergii en Guyane française. Elle permet d'aboutir à des recommandations précises et argumentées en matière de recherche comme de développement pour tout décideur impliqué. Aquaculture is one of the main supply of protein in feed for mankind, notably in Asia. It increases and had exceeded the level of production of world fisheries, which is decreasing. According to sites and rearing methods, aquaculture contributes to add value but also in some cases to impact negatively the aquatic ecosystems. In the coastal area, a rich and productive zone, but also a place of conflicts, this activity presents a high potential for development if it takes into account the rules of sustainability. The conditions of this sustainability may be cleared with appropriate methods of foresight analysis applied for each development project. The analysis of the professional experience of D. Lacroix for 33 years in aquaculture is structured in three steps. Firstly, the work is to check the scientific value of the research conducted under his responsibility in various contexts and for different responsibilities. This study refers to the requirements of a PhD. In the second part of the work, the results of few major projects (French West Indies, French Guyana….) are analysed with the support of the theory of translation (Callon et al) which allows to build a network of actors and to project it into the context. This way of study includes a special attention to the aspects of time planning, legitimacy and acceptability. Finally, the author examines how this knowledge gained from experience could help building a method for foresight analysis aiming at a shorter planning, a better timing and less means for future projects. To achieve this goal the author integrates the vision of the economist R. Passet which structures any project in an ecosystemic framework, including criteria of sustainability. The mix of these two approaches (Callon & Passet) entails in a new tool for foresight analysis, called Aster, which originality is to offer the possibility to test various scenarios and related consequences to help decision -makers. This new method of foresight analysis, is then tested on the well known case study of the development of prawn Macrobrachium rosenbergii in French Guyana. The test shows to be successful as it delivers precise and arguable recommendations about research and development for all stakeholders.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Other literature type 1994 FranceAuthors: Paquotte, Philippe;Aquaculture is an economic activity which is characterised by a great dependence on environmental conditions. Therefore aquaculture development is subdued to institutional context which defines the rules for use and conservation of the environment. This paper analyses the impact of marine environment regulations on economic operating of aquaculture enterprises and on industrial dynamics. Because aquaculture enterprises use a collective good, an economic approach of aquaculture has to take into account not only the relations between enterprises and environment, but also the relations between the enterprises themselves, through production externalities. In this study, several economic tools are considered in order to incite enterprises to integrate pad of the cost of their effects on the environment. But these public policies have to take into account the youth of the activity, the specific economic situation of the enterprises and the place of aquaculture in global coastal management. [NOT CONTROLLED OCR] L'aquaculture est confrontée à un cadre institutionnel définissant les conditions d'accès d'utilisation et de protection du milieu marin. La réglementation sur l'environnement va avoir un impact sur le fonctionnement économique des entreprises et sur la dynamique sectorielle de l'aquaculture. A partir de l'étude de la nature des relations entre entreprises et milieu, on peut proposer un certain nombre d'outils économiques permettant de faire prendre en compte par les entreprises une partie du coût de leurs effets sur l'environnement. Dans le cas particulier de l'aquaculture marine, cette réglementation doit cependant tenir compte de la jeunesse de l'activité, de la situation économique des entreprises et de leur rôle dans une politique d'aménagement du littoral.
