Résumé : International audience
In a period of agricultural decline in the uplands of Europe, agriculture is ceasing to provide the primary rationale for the organisation, utilisation and functioning of rural space. Policy reform, market trends and changes to the way citizens and consumers think about the countryside all suggest a need for thinking strategically about the future development of these areas. However, without a broad involvement of stakeholders, land use conflicts, and social and cultural conflicts in general, may increase. Involving stakeholders in upland areas can be facilitated by using scenario technique and by discussing alternative futures in local stakeholder panels. In this paper we present four scenarios of land-use change for the year 2030, and their assessments by stakeholder panels in Scotland, France, Norway, Switzerland, Slovakia and Greece. The aim of the paper is to explore the ways in which stakeholders in these locations advocate and assess these scenarios. We also explore how stakeholders in different countries weight the visual landscape impacts, the livelihood and biodiversity aspects of the scenarios in their assessment, and the reasons for their prioritising. The cross-country analysis shows that stakeholders across the study areas are united in their overall rejection of agricultural liberalisation, advocating a production-oriented, but multifunctional and environmentally-friendly agriculture that maintains landscapes and biodiversity.

Résumé : International audience
The main objective of the VULSACO (VULnerability of SAndy COasts to climate change and anthropic pressure) project was to investigate present day and potential future vulnerability of sandy coasts at the 2030 horizon, i.e. on a time scale related to climate variability. The method, based on a multidisciplinary approach bringing together geologists, geographers, physicists, social psychologists, engineers and stakeholders, was structured around 4 axes: field data analysis; numerical modelling; analysis of governance and stakeholder perceptions; and development of vulnerability indexes. This approach was designed to investigate vulnerability at a local scale and was applied to 4 contrasting beaches located in France: Sète Lido (Mediterranean Sea), Truc Vert and La Tresson beaches (Atlantic Ocean), and Dewulf (English Channel). The results focus on decadal and multi-annual beach trends at the Truc Vert beach site. There is almost no trend in beach volume at Truc Vert beach, although there is a variation in this parameter on a cycle of 2 to 3 yr, with variations related to wave energy and probably to indexes of climate variability. Numerical modelling identified the sensitivity of beach responses to changes in wave height and direction, especially in terms of subtidal morphology and the potential development of shoreline instability. Together with the observed offshore wave angle at the Biscay Buoy, these model results suggest that a potential change in wave angle due to climate variability could significantly modify the bars' morphology. The combination of data analysis and numerical modelling contributed to the development of vulnerability indexes designed for sandy coasts, which take into account climate-dependant variables such as waves. This allowed the differentiation of the sites in terms of vulnerability to erosion: Sète Lido and Truc Vert beach were the most and least vulnerable sites, respectively. These indexes help in identifying the dominant components of beach vulnerability, and provide potential for the study of how anthropogenic factors affect vulnerability. The study of stakeholder perceptions and decision-making with regard to climate-related risk also highlighted potential anthropogenic effects on beach vulnerability, and identified possible site-specific outcomes.

Résumé : International audience
1. Estimating forest above-ground biomass (AGB), or carbon (AGC), in tropical forests has become a majorconcern for scientists and stakeholders. However, AGB assessment procedures are not fully standardized andeven more importantly the uncertainty associated with AGB estimates is seldom assessed.2. Here, we present an R package designed to compute both AGB/AGC estimate and its associated uncertaintyfrom forest plot datasets, using a Bayesian inference procedure. The package builds upon previous work onpantropical and regional biomass allometric equations and published datasets by default but it can alsointegrate unpublished or complementary datasets in many steps.3. BIOMASS performs a number of standard tasks on input forest tree inventories: i) tree speciesidentification, if available, is automatically corrected; ii) wood density is estimated from tree species identity;iii) if height data are available, a local height-diameter allometry may be built; else height is inferred frompantropical or regional models; iv) finally, AGB/AGC are estimated by propagating the errors associated withall the calculation steps up to the final estimate. R code is given in the paper and in the appendix forillustration purpose.4. The BIOMASS package should contribute to improved standards for AGB calculation for tropical foreststands, and will encourage users to report the uncertainties associated with stand-level AGB/AGC estimatesin future studies.

Résumé : International audience
It is now well recognized that information management systems often deal with geographic information even if they often do not take advantage of it. In these systems, requirements engineering (RE) is becoming more and more important in helping stakeholders to model their requirements regarding the quality of the data.However, to date, few RE projects take geographic information and geographic constraints into account. We thus propose to study in this paper the question of managing such geographic constraints in the framework of RE. We propose an extension of the RE model and its implementation within the KAOS framework, and the use of geographic ontologies

Résumé : International audience
Effective and sustainable prevention of work-related musculoskeletal disorders (WR-MSDs) remains a challenge for preventers and policy makers. Coordination of stakeholders involved in the prevention of WR-MSDs is a key factor that requires greater reflection on common knowledge and shared representation of workers’ activities among stakeholders. Information on workers’ strategies and operational leeway should be the core of common representations, since it places workers at the center of the “work situation system” considered by the intervention models. Participatory ergonomics permitting debates among stakeholders about workers’ activity and strategies to cope with the work constraints in practice could help them to share representations of the “work situation system” and cooperate. Sharing representation therefore represents a useful tool for prevention, and preventers should provide sufficient space and time for dialogue and discussion of workers’ activities among stakeholders during the conception, implementation and management of integrated prevention programs

Résumé : This paper presents a survey of French Eastern English Channel fishers' observations of the past and current state of the marine ecosystem and their wishes for the future, as a first step towards formulating management objectives. Twenty-nine semi-directive interviews were carried out in June 2006 among fishers and shellfish farmers. Cognitive maps proved useful to formalise their experience and knowledge. Most interviewees mentioned a decrease of the resource in recent years and pointed out the presence of several problems, such as pollution, degradation of the ocean floor and harmful impacts of human activities, including fishing. The indicators used by the fishers as the basis to form their opinion were similar to those generally used by scientists for assessing the state of exploited marine populations and communities (average fish length, CPUE, fished biomass...); additional indicators were the timing and duration of fishing seasons.

Résumé : The diversity of reef ecosystems, the multiplicity of reef resource uses and the breadth of the range of the island socio-cultural contexts concerned make coral reef fisheries (CRF) management in the South Pacific a complex task. The health and state of the targeted resources depend both on ecosystem characteristics (as determined by ecological and biological factors) and on fishing pressure, whose effects are only partly known. Increasing harvests from commercial and recreational fishing increasingly overlap with traditional Subsistence activity, creating an important CRF management challenge. This paper presents a new approach to CRF assessment and monitoring by providing a set of multidisciplinary indicators. The fisheries system is assessed from three different viewpoints: ecology of targeted populations, exploitation and the broader socio-econornic fishery context. The use of complementary indicators chosen from each of these fields could balance the chronic lack of human and financial resources for the management of these fisheries. We suggest the use of these indicators through an assessment grid or an indicator dashboard specifically adapted to given situations and management objectives determined through a participatory approach. The operational efficiency of this dashboard depends on i) dialogue between users, ii) the objectivity of the proposed monitoring, iii) the Visual transcription of divergent/convergent interests amongst stakeholders, and iv) stakeholder involvement in the decision-making process. The use and constraints of such a tool are described with reference to Ouvea atoll (New-Caledonia, South Pacific) for which an analysis of available indicators for assessing fisheries status is presented.
La diversité des écosystèmes coralliens, la multiplicité des modalités d'exploitation de leurs ressources et l'hétérogénéité des contextes socio-culturels insulaires rendent complexe la gestion des pêcheries récifo-lagonaires du Pacifique sud. La santé et l'évolution de ces ressources dépendent, d'une part, des caractéristiques propres de l'écosystème (obéissant à des facteurs biologiques et écologiques) et, d'autre part, de la pression de pêche dont certains effets seulement sont établis. La pêche traditionnelle aux fins de subsistance est aujourd'hui concurrencée par des activités à visées commerciales et récréatives, qui accroissent les prélèvements et soulèvent de nouveaux enjeux de gestion. L'article propose une approche pour l'évaluation et le suivi de ces pêcheries basée sur un ensemble d'indicateurs pluridisciplinaires. Le système « Pêche » est analysé de trois points de vue complémentaires : l'écologie des peuplements exploités, l'exploitation halieutique sensu stricto et le contexte économique et social plus large des pêcheries. La mise en place d'indicateurs issus de ces trois domaines vise à compenser le manque chronique de moyens financiers et humains pour la gestion des pêcheries coralliennes des îles du Pacifique sud. Nous suggérons que leur utilisation s'effectue au travers d'une grille d'évaluation ou tableau de bord répondant à des situations précises et des objectifs de gestion définis lors d'une approche participative. La portée opérationnelle de ce tableau de bord de gestion de la pêche repose sur i) la concertation engagée entre les usagers, ii) l'objectivité du suivi préconisé, iii) la transcription visuelle des intérêts convergents et/ou divergents des acteurs, et iv) leur implication dans le processus de décision. Les modalités et contraintes d'application de cet outil sont décrites sur l'exemple de l'atoll d'Ouvéa (Nouvelle-Calédonie, Pacifique Sud), pour lequel une analyse des indicateurs disponibles pour décrire l'état des pêcheries a été réalisée.

Résumé : International audience
This paper describes an operational protocol for integrating conservation and restoration with land-use planning in islands. Conservation challenges are intensified in insular systems due to higher ecosystem vulnerability, limited spatial options, low data availability, rapid land-use change and, globally, short-term vision planning. Our operational planning protocol integrates ecological and socio-economic factors to identify the best spatial options for conserving and restoring biodiversity, inside and outside extant reserves, while minimising future land-use conflicts. Conservation and restoration targets are formulated for species, habitats and ecological processes that support biodiversity. An optimal network of priority sites is selected to achieve those targets across the landscape. The prioritisation process integrates a Conservation Costs Index to optimise conservation and restoration investments. We discuss the outcomes of the planning protocol in terms of site prioritisation, stakeholders' participation and general implications for spatial planning in insular systems. As with many islands, the study area of Réunion Island has experienced rapid urban and agricultural expansion, which threatens its unique biodiversity. Forty three per cent of the island is currently protected in a National Park but only half of this reserve network contributes to the achievement of targets. An additional 21% of land should be conserved mainly to ensure the persistence of ecological connections between the marine, terrestrial and freshwater realms. Finally we emphasize that our method doesn't substitute the land-use planning debate but is aimed to better prepare the conservation sector for negotiating future land-use allocation with other socio-economic sectors in islands

Résumé : The results of a survey on fishers' perceptions of recent changes in the eastern English Channel ecosystem carried out in 2006 were compared with fishery and bottom-trawl survey data. A hypothesis-testing framework was used, testing the null hypothesis that fishers' statements were true, which permitted evaluation of both agreement and disagreement. Overall good agreement between fishers' statements and scientific data was found, and both sources suggested that the fish community in the Channel is undergoing large changes, among which are decreases in some commercially important species; in addition, a number of human pressures impact the ecosystem. Fishers had an accurate perception of changes and their time-frames, but not necessarily of their causes. They had a greater power than survey data to detect recent changes, showing that fishers' perceptions have great potential as early warning signals.

Physiomar 08 followed the very successful workshop 'Physiological aspects of reproduction and nutrition in marine mollusks' held in La Paz (Mexico) in November 2006 under the guidance of Maria Concepcion Lora Vilchis and Elena Palacios Metchenov from CIBNOR. This year's meeting has focus on Reproduction, Growth, Nutrition and Genetics and genomics of marine molluscs, and included a specific session on the effects of climate change on mollusc physiology: Global change. This conference has served as a forum for the communication of recent advances in all aspects of the physiology in molluscs. Researchers, students, stakeholders and mollusc farmers have had the opportunity to communicate personally in a friendly environment with leaders in the field. This meeting aimed to provide a vehicle for continuing exchanges, cooperation, and collaboration in the field of the physiology of marine molluscs to better understand their adaptation ability in a changing environment, their ecological significance, and to promote their sustainable culture.

Résumé : International audience
Coral reef fisheries support the development of local and national economies and are the basis of important cultural practices and worldviews. Transitioning economies, human development, and environmental stress can harm this livelihood. Here we focus on a transitioning social-ecological system as a case study (Moorea, French Polynesia). We review fishing practices and three decades of effort and landing estimates with the broader goal of informing management. Fishery activities in Moorea are quite challenging to quantify because of the diversity of gears used, the lack of centralized access points or markets, the high participation rates of the population in the fishery, and the overlapping cultural and economic motivations to catch fish. Compounding this challenging diversity, we lack a basic understanding of the complex interplay between the cultural, subsistence, and commercial use of Moorea's reefs. In Moorea, we found an order of magnitude gap between estimates of fishery yield produced by catch monitoring methods (2 t km −2 ∼ year −1) and estimates produced using consumption or participatory socioeconomic consumer surveys (∼24 t km −2 year −1). Several lines of evidence suggest reef resources may be overexploited and stakeholders have a diversity of opinions as to whether trends in the stocks are a cause for concern. The reefs, however, remain ecologically resilient. The relative health of the reef is striking given the socioeconomic context. Moorea has a relatively high population density, a modern economic system linked into global flows of trade and travel, and the fishery has little remaining traditional or customary management. Other islands in the Pacific in similar contexts in Polynesia such as Hawaii, that continue to develop economically, may have small-scale fisheries that increasingly resemble Moorea. Therefore, understanding Moorea's reef fisheries may provide insight into their future.

Résumé : Environmental management decisions based upon indicators are the end point of a process involving stakeholders and scientists. These steps should be explicit and follow a chronology. This paper presents a general framework for the design and use of management-oriented indicators, integrating management questions and performance criteria. We first examined the desirable characteristics of indicators aimed at providing decision-support for marine environmental management. Ideally, one should select the indicator that guarantees a safe and unambiguous decision leading to the appropriate measures in terms of regulation, remediation or control. In the present study, indicators are assessed according to two criteria: relevance and effectiveness. Relevance encompasses sensitivity and the existence of quantitative reference values, thereby allowing the selection of potential indicators. Effectiveness is the ability of the indicator to reach its predefined targets based on optimal (or at least improved) data collection protocols. The framework is illustrated by applying it to the European Water Framework Directive and to the Marine Protected Area management contexts. (C) 2010 Elsevier Ltd. All rights reserved.

Résumé : The purpose of this thesis is to improve the knowledge about and apply data mining techniques and some Bayesian model in the field of social and environmental health inequalities. On the neighborhood scale on the Paris, Marseille, Lyon and Lille metropolitan areas, the health event studied is infant mortality. We try to explain its risk with socio-economic data retrieved from the national census and environmental exposures such as air pollution, noise, proximity to traffic, green spaces and industries. The thesis is composed of two parts. The data mining part details the development of a procedure of creation of multidimensional socio-economic indices and of an R package that implements it, followed by the creation of a cumulative exposure index. In this part, data mining techniques are used to synthesize information and provide composite indicators amenable for direct usage by stakeholders or in the framework of epidemiological studies. The second part is about Bayesian models. It explains the "BYM" model. This model allows to take into account the spatial dimension of the data when estimating mortality risks. In both cases, the methods are exposed and several results of their usage in the above-mentioned context are presented. We also show the value of the socio-economic index procedure, as well as the existence of social inequalities of infant mortality in the studied metropolitan areas.
Cette thèse a pour but d'améliorer les connaissances concernant les techniques d'analyse de données et certains modèles bayésiens dans le domaine de l'étude des inégalités sociales et environnementales de santé. À l'échelle géographique de l'IRIS sur les agglomérations de Paris, Marseille, Lyon et Lille, l'événement sanitaire étudié est la mortalité infantile dont on cherchera à expliquer le risque avec des données socio-économiques issues du recensement et des expositions environnementales comme la pollution de l'air, les niveaux de bruit et la proximité aux industries polluantes, au trafic automobile ou aux espaces verts. Deux volets principaux composent cette thèse. Le volet analyse de données détaille la mise au point d'une procédure de création d'indices socio-économiques multidimensionnels et la conception d'un package R l'implémentant, puis la création d'un indice de multi-expositions environnementales. Pour cela, on utilise des techniques d'analyse de données pour synthétiser l'information et fournir des indicateurs composites utilisables directement par les décideurs publics ou dans le cadre d'études épidémiologiques. Le second volet concerne les modèles bayésiens et explique le modèle " BYM ". Celui-ci permet de prendre en compte les aspects spatiaux des données et est mis en œuvre pour estimer le risque de mortalité infantile. Dans les deux cas, les méthodes sont présentées et différents résultats de leur utilisation dans le contexte ci-dessus exposés. On montre notamment l'intérêt de la procédure de création d'indices socio-économiques et de multi-expositions, ainsi que l'existence d'inégalités sociales de mortalité infantile dans les agglomérations étudiées.

Résumé : International audience
The issue of drinking water quality compliance in small and medium scale water services is of paramount importance in relation to the 98/83/CE European Drinking Water Directive (DWD). Additionally, concerns are being expressed over the implementation of the DWD with respect to possible impacts on water quality from forecast changes in European climate with global warming and further anticipated reductions in north European acid emissions. Consequently, we have developed a decision support system (DSS) named ARTEM-WQ (AwaReness Tool for the Evaluation and Mitigation of drinking Water Quality issues resulting from environmental changes) to support decision making by small and medium plant operators and other water stakeholders. ARTEM-WQ is based on a sequential risk analysis approach that includes consideration of catchment characteristics, climatic conditions and treatment operations. It provides a holistic evaluation of the water system, while also assessing human health risks of organic contaminants potentially present in treated waters (steroids, pharmaceuticals, pesticides, bisphenol-a, polychlorobiphenyls, polycyclic aromatic hydrocarbons, petrochemical hydrocarbons and disinfection by-products; n = 109). Moreover, the system provides recommendations for improvement while supporting decision making in its widest context. The tool has been tested on various European catchments and shows a promising potential to inform water managers of risks and appropriate mitigative actions. Further improvements should include toxicological knowledge advancement, environmental background pollutant concentrations and the assessment of the impact of distribution systems on water quality variation.

Résumé : Cet article explore les raisons qui incitent des acteurs sociaux, politiques et économiques à choisir de mettre les ressources naturelles en valeur, par et pour l’écotourisme. Il pose l’hypothèse que l’attractivité de la nature — sur laquelle s’appuie l’écotourisme — n’est pas neutre, c’est-à-dire que les acteurs impliqués dans la sauvegarde de celle-ci le font principalement par intérêt. Par son lien étroit avec la biodiversité, dont les dimensions ne sont pas accessibles à tous, l’écotourisme constitue un vecteur de développement et de consolidation du pouvoir, en particulier celui de « l’éco-pouvoir », c’est-à-dire celui des acteurs qui détiennent les informations sur l’état des ressources naturelles et sur les solutions qui leur sont accessibles.
This article explores the reasons why the social, political and economic stakeholders choose to promote natural resources by means of and for ecotourism. It hypothesizes that the attractiveness of nature-based ecotourism is not revenue neutral - that is, those involved in promoting this approach do so out of self interest. Through its close relationship with biodiversity, the dimensions of which are not appreciated by all, ecotourism is a vehicle for development and consolidation of power, particularly that of "éco-power", that is say those stakeholders who have information on the state of natural resources and the solutions available to them.

Résumé : Cet article analyse les interactions socioculturelles d’acteurs multiples ayant des intérêts divergents en regard de la reconnaissance d’un espace naturel à titre d’aire protégée, plus particulièrement le Parc marin du Saguenay–Saint-Laurent (PMSSL), situé au Québec à l’embouchure de la rivière Saguenay. Compris dans le sens d’espace socialisé et investi de valeurs parfois contradictoires, ce territoire constitue le cas empirique sur lequel repose l’analyse des logiques d’acteurs. La perspective ici mise de l’avant repose à la fois sur une décision de l’État de créer et de mettre en valeur une aire marine ainsi que sur la participation active des collectivités territoriales dans la gestion du patrimoine environnemental et culturel lié à leur identité propre. Si la participation des communautés locales apparaît comme un élément essentiel et démocratique dans la reconnaissance d’un espace naturel protégé, il apparaît tout aussi capital de bien saisir la logique qui sous-tend les actions de l’État et du milieu. Les résultats empiriques montrent deux logiques d’action distinctes à l’œuvre, une logique classique de planification et implantation stratégiques de l’état réservant une espace de participation programmée pour la communauté et une logique stratégique communautaire à caractère émergent, de portée moins englobante, mais adaptable aux nouvelles réalités et contraintes gouvernementales. Les résultats peuvent être représentés sous forme d’un processus de gouvernance à l’œuvre, un caractérisé par une participation de base, mais un qui suggère qu’un processus plus hautement démocratique nécessiterait un plus haut degré de vigilance dans la perspective communautaire, suffisante pour produire une meilleure symétrie de pouvoir démocratique entre l’État.
This paper analyzes the socio-cultural dynamic between multiple stakeholders with divergent interests concerning the formalization of the status of a natural area into a protected area. The empirical case under analysis is the creation of the Saguenay Marine Park located at the confluence of the St-lawrence and Saguenay rivers in Québec, a rural region represented by different localities showing some contradictions in socio-economic values and agendas. The dual perspective put forth is, first, the governmental decision one to create and promote a marine protected area, and second, the regional community one to participate in the process and adapt the management of their cultural and environmental heritage to their own perception of their socio-economic identity. The objective of analysis is to identify the logics of action underlying both processes. The empirical results show two distinct logics at work, a government logic of classic managerial planning and implementation into which the community has a programmed role and a community logic of emergent planning, less comprehensive in scope, but adaptable to the emerging realities and limitations of the governmnent one. They can be seen in tandem as representing a governance process at work, one with a basic participative character, but one which suggests that an enhanced democratic process entails a higher vigilance level from a community perspective, such as to produce a more even democratic symmetry of powers between the State and the regional community.

Résumé : Evaluer les retombées économiques de manifestations sportives sur les territoires d’accueil est l’une des conditions permettant de décider de la pérennisation ou non de ces évènements. Cette évaluation revêt une grande importance pour les prestataires de services, les institutionnels et les diverses entreprises qui y sont engagés, car elle leur permet d’avoir une vision plus claire du marché, et le cas échéant d’ajuster et d’affiner leur politique évènementielle pour l’avenir. Aujourd’hui, apparaît de plus en plus un besoin croissant d’évaluation de la part de praticiens et d’acteurs publics impliqués dans les activités sportives. Ces derniers comme le grand public s’interrogent quelquefois sur l’utilité ou la pertinence économique et sociale de tels évènements.Aussi, l’objectif prioritaire de cette étude est de proposer dans le cas de la Guadeloupe, à partir d’un cadre conceptuel précis et d’une méthodologie partagée et éprouvée, une évaluation territoriale de l’impact économique et social de la Route du rhum, en retenant deux approches: l’une en niveau, déterminant successivement les valeurs du multiplicateur input-output à l’aide d’un tableau entrées-sorties (TES) de l’économie guadeloupéenne, et du multiplicateur de la base qui s’appuie sur les résultats d’une méta-analyse; l’autre , dynamique, spécifie par un modèle économétrique l’influence de la Route du rhum et d’autres variables sur la croissance économique de la Guadeloupe. L’enjeu consiste à se doter collectivement de points de repère afin que les différents acteurs de ce sport puissent situer les effets de leurs actions par rapport à d’autres pratiques, d’autres territoires, et à clarifier le niveau de contribution économique de cette activité sportive sur le territoire de Guadeloupe. Les résultats obtenus convergent et montrent qu’en dépit d’un succès indéniable au plan sportif et médiatique, la Route du rhum, évènement sportif de voile de haut niveau reliant tous les quatre ans St Malo à Pointe-a-Pitre, enregistre au plan économique des résultats modestes si l’on en juge à la fois par les médiocres retombées induites en matière de fréquentation touristique, par les faibles coefficients multiplicateurs de revenu affichés, par un ratio coût-bénéfice défavorable et par les incidences mineures que provoque cet évènement sur la croissance économique régionale.
Evaluation of economic effects from sport events is necessary to pursue or not these events. This evaluation is important for enterprises that provide goods and services also for the government, because it allows them to obtain an accurate vision of the future.Today, we have a growing need of evaluation from the people involved in sport activities. Sometimes, these people ask themselves on economic and social advantages of these events.The objective of this paper is to propose for Guadeloupe a rigourous methodology that assesses the economic and social impact of Route du rhum which is a transatlantic competition between St-Malo and Pointe-a-Pitre. We use two approaches: the first of which is level-based and determines the values of both economic base multipliers and input-output multipliers by composing an input-output table of the Guadeloupe economy. The second, dynamic approach specifies from an econometric model the impact of several variables, especially those of la Route du rhum. The goal is to provide findings to stakeholders of this sport for comparison. The results of the investigation merge and show globally weak economic performance of Route du rhum, particularly a poor cost-benefit ratio, weak economic multipliers and inter-industry linkages.
