Description : Des lectures épistémologiques sur les réseaux (définition, type, qualités sociaux et/ou mondiaux) en tant que supports technologiques de l'innovation, nous permettront, grâce à ce cadre méthodologique de circonscrire les enjeux et les impacts de ceux-ci dans les territoires et plus spécifiquement dans la complexité actuelle du mode de gouvernance des localités. Notre propos sera de montrer à partir de l'appropriation des TIC et de nouveaux modes d'existence des objets techniques que l'innovation sociale naît et se diversifie de façon interculturelle à partir d'hybridations complexes entre préoccupations économiques, relations avec les pouvoirs publics et utilité sociale. Notre société, forte de son implication par les réseaux numériques a dès lors une demande sociale en participation et en politique publique. Une co-construction, en liens avec les différentes instances décisionnelles du territoire local est sollicitée.

Description : Acknowledging the contribution of agriculture to global changes and its negative impacts on the environment, it is now seen as unavoidable for it to participate to the ecological transition. This research aims to understand the performativity of legal texts. This performativity does not only reveal the institutions? approach of the model to implement. It also aims to change, in the meantime, the reality (Ambroise et al., 2015). The objective of this research is to stress the importance of concepts? definitions in policies implementation when agricultural system reframing is at stake, and to highlight an uncertain use of words may produce. However, little attention is given to the choice of terms concerning the definition of a greener agriculture in official texts: terms are often mixed up without any clarification. Applying content analysis to official documents, we provide an analytical grid to grasp in what extent the unclear use of words and what they namely designate, lead to ambiguous policies eluding aspects of the concept of agroecology underlined by researchers or associations. We also shed light on the local appropriation process of the concept and its specification in the French Indies. Reconnaissant la contribution de l'agriculture aux changements globaux et à ses impacts négatifs sur l'environnement, on le voit maintenant comme inévitable pour qu'il participe à la transition écologique. Objectifs de ces recherches pour comprendre le performativity des textes juridiques. Ce performativity indique non seulement l'approche des établissements du modèle à l'instrument. Il vise également à changer, dans le même temps, la réalité (Ambroise et autres, 2015). L'objectif de cette recherche est de souligner l'importance des définitions des concepts dans l'exécution de politiques quand le système agricole reframing est en jeu, et accentuer une utilisation incertaine des mots peut produire. Cependant, peu d'attention est accordée au choix des termes au sujet de la définition d'une agriculture plus verte en textes officiels : des termes sont souvent mélangés sans n'importe quelle clarification. S'appliquant à l'analyse du contenu aux documents officiels, nous fournissons une grille analytique à la prise dans quelle ampleur l'utilisation peu claire des mots et ce qu'ils à savoir indiquent, mènent aux politiques ambiguës éludant des aspects du concept de l'agroécologie souligné par des chercheurs ou des associations. Nous avons également jeté la lumière sur le processus local d'appropriation du concept et de ses spécifications dans les Antilles françaises.

Description : The methodology is supported on the basis of the experience acquired by a group of researchers, farmers and technicians from Cuba in the implementation of Participatory Plant Breeding. The proposal presents a number of methodological considerations with the necessary flexibility to allow proper application of the method and follows a logical sequence of activities to be executed in a manner that facilitates their implementation in various contexts in which it is of interest to apply. Its implementation, as such, is a learning process in action for all actors involved in it; also enables participants to understand the scale of the needs of the producers and breeding programs and dissemination of varieties in terms of the real interest of these. The methodology has 4 main phases: 1) diagnosis, 2) Collection of plant genetic resources, 3) Establishment of demonstration plots and development diversity fairs and 4) farmer experimentation. Besides the four basic stages of Participatory Plant Breeding in Cuba other tools that allowed the PPB constitute a successful process were used, these tools are: action learning as interest Schools Farmers Festivals innovation, exchange visits and retreats, capacity building of students on stage in local innovation and creation of local seed banks.

Résumé : International audience
Two genome-wide association studies (GWASs) recently highlighted the HLA-DRA and HLA-DRB5 genes as associated with Parkinson disease (PD). However, because HLA-DRA displays a low level of polymorphisms and HLA-DRB5 is only present in approximately 20% of the population, these findings are difficult to interpret. Our aims were: (1) to replicate and investigate in greater detail the association between PD and the HLA-DR region; (2) to identify PD-associated HLA alleles; and (3) to perform a meta-analysis of our top finding. As part of 2 French population-based case-control studies of PD including highly ethnically homogeneous participants, we investigated the association between PD and 51 Single-nucleotide polymorphisms (SNPs) in the HLA-DR region. HLA-DRB1 alleles were imputed using the HLA(*) IMP software. HLA typing was performed in a subsample of the participants. We performed a meta-analysis of our top finding based on 4 GWAS data sets. Among 499 cases and 1123 controls, after correction for multiple testing, we found an association with rs660895 (OR/minor allele, 0.70; 95% CI, 0.57-0.87) within the HLA-DRB1 gene, which encodes the most polymorphic HLA-DR chain (DRβ). A meta-analysis (7996 cases, 36455 controls) confirmed this association (OR, 0.86; 95% CI, 0.82-0.91; P < .0001). SNP-based imputation of HLA alleles showed an inverse association between PD and the HLA-DRB1(*) 04 allele. We replicated an association between PD and the HLA-DR region and provided further insight into the loci and alleles involved. The highly polymorphic HLA-DRB1 locus contains rs660895, which represents a more legitimate candidate than previous ones. Our finding is in agreement with the hypothesis of an immune component in PD pathophysiology. © 2012 Movement Disorder Society.

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 : (Funding) Support for the development of the technical infrastructure and partner training provided by the United States Department of Education TICFIA program.
While the global response to HIV and AIDS has realized several successes in achieving universal access to prevention, care and treatment to date, challenges persist in ensuring equal access to these services for most at risk populations. The epidemiology of HIV reflects a stark disparity in access to prevention and treatment services for neglected most-at risk populations, such as men who have sex with men (MSM). World-wide, MSM often experience higher rates of HIV relative to the total population. The reasons for this dynamic are multi-faceted and include high risk behaviors, and cultural as well as structural barriers. For MSM in developing countries, for example, basic services for prevention and treatment of HIV infection have yet to reach the large majority of men. Homophobia and discrimination limit access of MSM to prevention services and markedly increase vulnerability, as do criminalization of same-sex behavior. Decriminalization of same-sex behavior is a structural intervention for prevention of HIV infection and has recently been embraced by a nonbinding statement from the United Nations (Beyrer C,Clin Infect Dis. 2010 May 15;50 Suppl 3:S108-13) In the Caribbean, all of the above mentioned barriers exist. In fact, recent evidence demonstrates that there is a correlation between the decriminalization of homosexuality and lower rates of HIV (UNAIDS). This correlation is attributed to improved access to services. Therefore, The United Nations Development Program (UNDP) has recently launched an initiative to address the current situation regarding men who have sex with men in Guyana where the HIV prevalence in this population is 19.4% in contrast to 1.8% in the total population. This rapid assessment has been commissioned to supplement two previous studies that were conducted in Guyana in informing the design of upcoming activities to support local capacity building to enhance access to services and respect for the human rights protections for MSM. Unfortunately, in Guyana, like much of the Caribbean, MSM tend to be a hard to reach population, perhaps due to elevated levels of stigma and discrimination and difficulty in accessing men who might participate in high risk same sex behaviors yet do not self-identify as an MSM. As a result, there is a relative paucity of data concerning the knowledge, attitudes and behaviors of this total population in Guyana. (i.e. those who self –identify and those who do not) The baseline report is organized as follows: the methodology is explained followed by the study limitations, the review (literature and desk). The report then proceeds with describing the reality of work and working with sexual and gender minorities in Guyana, the status quo and entry points. The main findings of the capacity assessment and focus groups are then discussed. Issues relating to the uniformed forces and health services providers are then presented followed by discussions and conclusions.

Résumé : International audience
In order to ensure a sustainable management of reef fisheries, data need to be collected regularly on the effect of these fisheries on both fish resources and the ecosystems that sustain them. Habitat and resources monitoring programs can provide such information, but are difficult to implement as they involve a range of technical, financial and human resources. Regarding these problems, the involvement of the local population in monitoring programs, called participatory monitoring, seems to offer solutions. Indeed, participatory monitoring has the potential of increasing the number of data collected at low cost, while taking advantage of the traditional ecological knowledge available locally. Some questions need clarifying, however: which methods can bring relevant information for the monitoring of reef fisheries while being appropriate to the motivations and skills of the local population? Is the degree of participation of the local population sufficient to make the monitoring program work, particularly over the long term? To answer these questions, participatory monitoring methods commonly used for coral reef ecosystems have been implemented to assess reef fisheries at three different sites: Moorea island and Tikehau atoll in French Polynesia, and the Bay of Tulear in Madagascar. While highlighting the relevance of some participatory monitoring programs for snapshot and large-scale surveys, the results of this study also show their lesser interest for regular data gathering on long-time scales. In any case, strong coordination and supervision by scientists are considered essential.
La gestion durable des écosystèmes coralliens nécessite de disposer d’informations régulières concernant l’impact des pêcheries sur les ressources récifales et sur les écosystèmes dont elles dépendent. Les suivis intégrés des ressources, des habitats et des espèces associées qui visent à fournir ce type d’informations sont difficiles à mettre en œuvre, car ils impliquent de nombreuses ressources humaines, techniques et financières. Face à ces problèmes, la participation de la société civile dans les programmes de suivi semble en mesure d’apporter des solutions. Dans le but de tester cette hypothèse, des méthodes de suivi participatif ont été mises en œuvre afin de caractériser des pêcheries récifales sur trois socio-écosystèmes contrastés : l’île de Moorea et l’atoll de Tikehau en Polynésie française, et le littoral de Tuléar à Madagascar. Les résultats de cette étude soulignent la pertinence de certains suivis participatifs pour fournir une vision écosystémique dans le cas de collecte de données ponctuelles et de large envergure, et leur intérêt moindre pour la collecte continue de données sur de longues échelles de temps. Dans tous les cas, une structure de coordination et l’implication de scientifiques s’avèrent primordiales pour assurer pérennité et fiabilité au système de suivi.

Description : Many rural areas in Suriname are lacking information on technology from extension agents from the government extension agency, and research institutes. Communication and informal voices of farmers are shared by media. As part of a baseline study conducted for the sixth operational strategic plan of the Small Grants Programme in Suriname, four communities were selected: Moengo, Pokigron, Nickerie, Sipaliwini and Para. The purpose of this study was to collect data from communities regarding problems related to climate change, agricultural innovation and landscape management. This qualitative study was done through the focus group method. Eight focus group meetings were organized and consisted of 8-15 participants each. The key questions were extracted from the SEPLS method (Socio-ecological Production Landscapes and Seascapes). The data was analyzed through the SWOT method. Based on the results, the communities have a good level of awareness about management of their landscapes. Improvement of agriculture management will be possible by access to innovative and new knowledge developed in and outside the community. Climate change is an important issue that the community already is aware of, they developed their own local strategy in resilience to this issue. Beaucoup de zones rurales au Surinam manquent d'information sur la technologie des agents de vulgarisation de l'agence d'extension de gouvernement, et des instituts de recherche. La communication et les voix informelles des agriculteurs sont partagées par media. En tant qu'élément d'une étude de ligne de base entreprise pour le sixième plan stratégique opérationnel du petit programme de concessions au Surinam, les quatre communautés ont été sélectionnées : Moengo, Pokigron, Nickerie, Sipaliwini et paragraphe. Le but de cette étude était de rassembler des données de communautés concernant des problèmes liés au changement climatique, à l'innovation agricole et à la gestion de paysage. Cette étude qualitative a été faite par la méthode de groupe cible. Huit réunions de groupe cible ont été organisées et se sont composées de 8-15 participants chacun. Les questions clé ont été extraites à partir de la méthode de SEPLS (des paysages et des paysages marins Socio-écologiques de production). Les données ont été analysées par la méthode de BÛCHEUR. Basé sur les résultats, les communautés ont un bon niveau de conscience au sujet de la gestion de leurs paysages. L'amélioration de la gestion d'agriculture sera possible par l'accès aux connaissances innovatrices et nouvelles développées à l'intérieur et à l'extérieur de la communauté. Le changement climatique est une question importante que la communauté a pris en compte et développé sa propre stratégie locale dans la résilience.

Résumé : International audience
Background: Heterogeneous patterns of malaria transmission are thought to be driven by factors including host genetics, distance to mosquito breeding sites, housing construction, and socio-behavioural characteristics. Evaluation of local transmission epidemiology to characterize malaria risk is essential for planning malaria control and elimination programmes. The use of geographical information systems (GIS) techniques has been a major asset to this approach. To assess time and space distribution of malaria disease in Bandiagara, Mali, within a transmission season, data were used from an ongoing malaria incidence study that enrolled 300 participants aged under six years old ". Methods: Children's households were georeferenced using a handheld global position system. Clinical malaria was defined as a positive blood slide for Plasmodium falciparum asexual stages associated with at least one of the following signs: headache, body aches, fever, chills and weakness. Daily rainfall was measured at the local weather station. Landscape features of Bandiagara were obtained from satellite images and field survey. QGIS™ software was used to map malaria cases, affected and non-affected children, and the number of malaria episodes per child in each block of Bandiagara. Clusters of high or low risk were identified under SaTScan W software according to a Bernoulli model. Results: From June 2009 to May 2010, 296 clinical malaria cases were recorded. Though clearly temporally related to the rains, Plasmodium falciparum occurrence persisted late in the dry season. Two " hot spots " of malaria transmission also found, notably along the Yamé River, characterized by higher than expected numbers of malaria cases, and high numbers of clinical episodes per child. Conversely, the northeastern sector of the town had fewer cases despite its proximity to a large body of standing water which was mosquito habitat. Conclusion: These results confirm the existence of a marked spatial heterogeneity of malaria transmission in Bandiagara, providing support for implementation of targeted interventions. Background Malaria is one of the leading causes of morbidity and mortality in the world, with an estimated 3.3 billion people at risk of malaria [1]. The incidence of malaria worldwide is estimated to be 216 million cases per year, with 81% of these cases occurring in sub-Saharan Africa. Malaria kills approximately 655,000 people per year; 91% of deaths occur in sub-Saharan Africa [1], mostly in children under five years of age. In Mali, West Africa, malaria represents 36.5% of consultation motives in health center, it is a leading cause of morbidity and mortality children of less than five years of age and the first reason of anaemia in pregnant women [2]. Malaria transmission is seasonal. Malaria parasite transmission and clinical disease are characterized by important microgeographic variation, often between adjacent villages, households or families [3-8]. This local heterogeneity is driven by a variety of factors including human genetics [9,10], distance to potential breeding sites [11,12], housing construction

Résumé : International audience
BACKGROUND: Thrombophilias are common disorders that increase the risk of pregnancy-associated venous thromboembolism and pregnancy loss and can also increase the risk of placenta-mediated pregnancy complications (severe pre-eclampsia, small-for-gestational-age infants, and placental abruption). We postulated that antepartum dalteparin would reduce these complications in pregnant women with thrombophilia. METHODS: In this open-label randomised trial undertaken in 36 tertiary care centres in five countries, we enrolled consenting pregnant women with thrombophilia at increased risk of venous thromboembolism or with previous placenta-mediated pregnancy complications. Eligible participants were randomly allocated in a 1:1 ratio to either antepartum prophylactic dose dalteparin (5000 international units once daily up to 20 weeks' gestation, and twice daily thereafter until at least 37 weeks' gestation) or to no antepartum dalteparin (control group). Randomisation was done by a web-based randomisation system, and was stratified by country and gestational age at randomisation day with a permuted block design (block sizes 4 and 8). At randomisation, site pharmacists (or delegates) received a randomisation number and treatment allocation (by fax and/or e-mail) from the central web randomisation system and then dispensed study drug to the local coordinator. Patients and study personnel were not masked to treatment assignment, but the outcome adjudicators were masked. The primary composite outcome was independently adjudicated severe or early-onset pre-eclampsia, small-for-gestational-age infant (birthweight <10th percentile), pregnancy loss, or venous thromboembolism. We did intention-to-treat and on-treatment analyses. This trial is registered with ClinicalTrials.gov, number NCT00967382, and with Current Controlled Trials, number ISRCTN87441504. FINDINGS: Between Feb 28, 2000, and Sept 14, 2012, 292 women consented to participate and were randomly assigned to the two groups. Three women were excluded after randomisation because of ineligibility (two in the antepartum dalteparin group and one in the control group), leaving 146 women assigned to antepartum dalteparin and 143 assigned to no antepartum dalteparin. Some patients crossed over to the other group during treatment, and therefore for on-treatment and safety analysis there were 143 patients in the dalteparin group and 141 in the no dalteparin group. Dalteparin did not reduce the incidence of the primary composite outcome in both intention-to-treat analysis (dalteparin 25/146 [17.1%; 95% CI 11.4-24.2%] vs no dalteparin 27/143 [18.9%; 95% CI 12.8-26.3%]; risk difference -1.8% [95% CI -10.6% to 7.1%)) and on-treatment analysis (dalteparin 28/143 [19.6%] vs no dalteparin 24/141 [17.0%]; risk difference +2.6% [95% CI -6.4 to 11.6%]). In safety analysis, the occurrence of major bleeding did not differ between the two groups. However, minor bleeding was more common in the dalteparin group (28/143 [19.6%]) than in the no dalteparin group (13/141 [9.2%]; risk difference 10.4%, 95% CI 2.3-18.4; p=0.01). INTERPRETATION: Antepartum prophylactic dalteparin does not reduce the occurrence of venous thromboembolism, pregnancy loss, or placenta-mediated pregnancy complications in pregnant women with thrombophilia at high risk of these complications and is associated with an increased risk of minor bleeding.

Résumé : International audience
This paper presents our response to the first interna- tional challenge on Facial Emotion Recognition and Analysis. We propose to combine different types of features to automatically detect Action Units in facial images. We use one multi-kernel SVM for each Action Unit we want to detect. The first kernel matrix is computed using Local Gabor Binary Pattern histograms and a histogram intersection kernel. The second kernel matrix is computed from AAM coefficients and an RBF kernel. During the training step, we combine these two types of features using the recently proposed SimpleMKL algorithm. SVM outputs are then averaged to exploit temporal information in the sequence. To eval- uate our system, we perform deep experimentations on several key issues: influence of features and kernel function in histogram- based SVM approaches, influence of spatially-independent in- formation versus geometric local appearance information and benefits of combining both, sensitivity to training data and interest of temporal context adaptation. We also compare our results to those of the other participants and try to explain why our method had the best performance during the FERA challenge.

Résumé : Sur fond de crise du tourisme au Nord, de la globalisation de l’économie et de l’accélération des mobilités, une évolution des formes de développement touristiques semble à l’œuvre dans les confins géographiques. Dans certains territoires touristiques du fait de conflits dans l’usage des ressources naturelles, des pratiques récréatives alternatives émergent qui combinent une logique économique avec des préoccupations socio-environnementales.Notre article analyse l’apparition du tourisme scientifique dans la région « non-touristique » de Aysén, en Patagonie chilienne. Des acteurs d’un territoire se mobilisent selon des pôles culturels et des axes thématiques autour de projets pilotes, de recherche expérientielle et de médiations scientifiques innovantes. Sur ce front pionnier, un réseau informel d’acteurs coordonne ses actions pour aborder les problématiques sociales et environnementales de leur territoire. Opérateurs et prestataires pour le tourisme scientifique créent de manière participative une offre originale. Un système touristique alternatif, axé sur la protection de l’environnement, de la culture et des dynamiques sociales de la communauté d’accueil, favorise l’acquisition et le partage de savoirs entre scientifiques, acteurs locaux et visiteurs.Le tourisme scientifique s’inscrit-il dans une évolution globale des pratiques touristiques ? En proposant de dépasser les frontières, entre activités récréatives et le travail, de lieux de vie et de loisir, il apparaît comme l’expression d’un « après-tourisme ». L’hybridation des pratiques, une approche scientifique associée à l’esprit de la découverte inhérent au voyage, semble pouvoir relever des défis sociétaux liés à l’essor d’un tourisme globalisé. Alors que le tourisme est pensé depuis longtemps en termes de transfert de compétences, de modèles et d’ingénierie du Nord vers le Sud, une périphérie propose de nouveaux cadres de pensée, d’action et de participation qui renouvellent le sens du voyage.
In the context of a tourism crisis in the north, a globalized economy and an increase of mobility, a change in the forms of tourism development seems to occur in peripheral areas. In some tourism areas and due to conflicts over the use of natural resources, alternative recreational practices arise that combine economic needs and socio-environmental concerns.Our article analyzes the appearance of scientific tourism in the "non-tourist" region of Aysén, in Chilean Patagonia. Actors of a territory unite according to specific cultural poles and thematic axes through experiential research and innovative scientific mediation pilot projects. On this pioneer front, an informal network of stakeholders coordinates its actions to address the social and environmental issues of their territory. Operators and service providers for scientific tourism create an innovative offer in a participatory process. An alternative tourism system, focused on protecting the environment, the culture and social dynamics of the host community, promotes the acquisition and sharing of knowledge between scientists, local actors and visitors.Is scientific tourism part of a global evolution of tourism practices? By proposing to go beyond established boundaries, of recreational activities and work, everyday places and leisure areas, it appears as the expression of an “After-Tourism”. The hybridization of practices, a scientific approach associated with the spirit of the discovery inherent of the travel experience, seems to respond to the challenges of the community confronted to the rise of a globalized tourism. While tourism has always been thought of in terms of transfer of skills, models and engineering from the North to the South, a periphery offers new frameworks of thought, action and participation that renew the meaning of travel.
En un escenario de crisis del turismo en los países desarrollados, de la globalización de la economía y del incremento de las movilidades, una evolución de las formas de desarrollo del turismo parece estar en marcha en los confines geográficos. En ciertos territorios turísticos, debido a los conflictos de uso de los recursos naturales, prácticas recreativas alternativas surgen que combinan una lógica económica con preocupaciones socio-ambientales.El presente artículo analiza el surgimiento del turismo científico en la región “no-turística” de Aysén en la Patagonia chilena. Actores del territorio se unen según polos y temáticas científicas, a través de proyectos pilotos, de investigación experiencial y mediaciones científicas innovadoras. En este frente pionero, una red informal se organiza para abordar las problemáticas sociales y ambientales de su territorio. Operadores y proveedores de servicios para el turismo científico crean de manera participativa una oferta novedosa. Un sistema turístico alternativo, basado en el cuidado del medio ambiente, de la cultura y de las dinámicas sociales del comunidad de acogida, favorece la adquisición y el intercambio de conocimientos entre científicos, actores locales y visitantes. ¿Será la aparición del turismo científico la expresión de una evolución global de las practicas turísticas? Al invitar a que sean sobrepasadas las fronteras, entre actividades recreativas y el trabajo, lugares de vida y sitios de esparcimiento, este se presenta como un “Pos-Turismo”. La hibridación de las prácticas, una aproximación científica asociada al espíritu de descubrimiento inherente del viaje, parece poder resolver los desafíos de nuestras sociedades vinculados al auge de un turismo globalizado. Cuando el turismo suele ser pensado desde hace mucho, como un proceso de transferencia de capacidades, de modelos y de ingenierías, del Norte hacia el Sur, una periferia propone nuevos marcos conceptuales, de acción y de participación, que renuevan el sentido del viaje.

Résumé : Le tourisme est souvent présenté comme l’un des instruments d’un développement durable, même s’il connaît une expansion difficilement maîtrisable, au détriment du patrimoine environnemental, insulaire et littoral en particulier, comme dans les DOM-TOM.Le tourisme a des impacts, culturels et sociaux notamment, sur l’environnement. Les ressources du patrimoine alimentent de leur côté la demande et l’offre touristiques. Un tourisme assis sur une gestion ad hoc des ressources du patrimoine constitue un facteur puissant de durabilité du développement local. La soumission de l’activité touristique aux exigences de protection, de conservation et de gestion reproductible de la biodiversité et du patrimoine naturel, dans les aires protégées de la Caraïbe française en particulier, génère des approches, des stratégies et des comportements nouveaux. La démarche écotouristique appelle une gestion participative et intégrée des ressources et des espaces, et constitue un défi pour les opérateurs du tourisme comme pour les acteurs de l’environnement, et une opportunité de « réappropriation » de leur milieu de vie par les populations locales. Il faut alors en clarifier le concept et les implications ; puis en analyser les objectifs et les enjeux dans une perspective de développement durable.
Tourism often appears as one a tool for a sustainable development, even if it is not easy to control, in the détriment of island and costal environment heritage, as in French overseas regions. Besides the cultural and social impacts of tourism upon environment, the heritage resources nuture the touristic request and offer. If based on an appropriate management of those resources, it may be a strong incentive for local sustainable development. The respect of protection, conservation and sustainable management of biodiversity and natural resources by tourism, especially in the overseas regions of French West Indies, produces new approaches, strategies and behaviours. The ecotourism approach, calling for a joint and integrated management of resources and areas, is a challenge for tour operators as for environment actors, and brings local population an opportunity to reappropriate their life environment. Its concept and implications must then be clarified, before analysing its aims and stakes regarding sustainable development

Résumé : Preparative pyrolysis followed by liquid chromatographic separation and gas chromatography of hydrocarbons (Pyrolysis-LC-GC) were used to study the participation of terrestrial and/or aquatic compounds in the formation of humic substances in sediments. Analyses performed on humic substances from recent sediments sampled in the Elorn river estuary (France) show that these substances are similar in many respects to other lacustrine or marine humic substances, with regard, for instance, to their high nitrogen and sulphur content and their low aromaticity. Mass balances on pyrolysis products and group composition of the C-14+ fraction of the pyrolysates were performed. The distribution of the total alkane and alkene fraction, isocyclo alkanes and alkenes from these humic acid pyrolysates was compared to that of various reference humic acid pyrolysates. The biomarker study (distribution and hopanes/steranes ratios from humic acid pyrolysates) confirms the participation throughout the estuary of algal precursors in the formation of the studied compounds, irrespective of the location of the sampling zone (upstream, median or downstream part of the estuary).

Résumé : The development of large pelagic fishing in the French Antilles is an integral part of a difficult economic situation of the fishing sector in Martinique where this development can seem like a solution to increasingly acute problems. Indeed, for the regulatory authorities as well as for many participants in the sector, it is imperative to find solutions to the lack of profitability of a part of the fishing ships and to confront the regular increase of the share of imports in supplying Martinique with seafood. This question about the possibilities of developing large pelagic fishing is not new since it is already mentioned in the Notice from the Economic and Social Committee of the Martinique Region in 1982. We will not show in this document a detailed analysis of small-scale fishing in Martinique. Since the latter has been abundantly studied by the team of the Caribbean Oceanological and Halieutic Research Centre (PROHC) between 1985 and 1987, we will take up these principal conclusions (with which we are in full agreement) and bring them up to date based on data collected during our mission from 11 to 24 April 1988. The first section devoted to the supply structure (local fishing and imports) will attempt to define under what conditions large pelagic fishing can be developed. The second section will address marketing and demand. Indeed, at the same time as the problems of developing large pelagic fishing, we are faced with the question of the organisation of seafood markets. This organisation is a fundamental issue for the small-scale fishing sector in the French Antilles since its long-term future depends upon it by setting different prices and amounts exchanged according to the structure it is given. We will come to a conclusion on the economic conditions of developing a large pelagic fishery and organising a market, this based on research and study work already done. We will indicate which investigations must be conducted to complete the set of factors for decision support in this area. To perform this assessment, we reconstructed from the long series 1970-1986 (sometimes with significant inadequacies): these are presented as an appendix.
(OCR non controlé) Le développement de la pêche de grands pélagiques dans les Antilles Françaises s'inscrit dans un contexte économique difficile du secteur de la pêche en Martinique où ce développement peut apparaître comme une solution à des problèmes de plus en plus aigus. En effet, pour les autorités de tutelle ainsi que pour de nombreux intervenants dans le secteur, il est impératif de trouver des solutions au manque de rentabilité d'une partie des unités de pêche et de faire face à l'augmentation régulière de la part des importations dans l'approvisionnement de la Martinique en produits de la mer. Cette question sur les possibilités d'un développement de la pêche de grands pélagiques n'est pas nouvelle puisqu'elle est déjà évoquée dans l'Avis du Comité Economique et Social de la Région Martinique en 1982. On ne présentera pas dans ce document une analyse détaillée de la pêche artisanale en Martinique. Celle-ci ayant été abondamment étudiée par l'équipe du Pôle de Recherche Océanologique et Halieutique Caraïbe (PROHC) entre 1985 et 1987, on reprendra ces principales conclusions (avec lesquelles nous sommes en plein accord) en les actualisant à partir des informations recueillies lors de notre mission du 11 au 24 avril 1988. La première section consacrée à la structure d'offre (pêche locale et importations) s'attachera à définir dans quelles conditions peut être développée une pêche de grands pélagiques. Là seconde section traitera de la commercialisation et de la demande. En effet parallèlement aux problèmes de développement d'une pêche de grands pélagiques, se pose la question de l'organisation du marché des produits de la mer. Cette organisation est un enjeu primordial pour le secteur de la pêche artisanale dans les Antilles Françaises puisqu'elle conditionne son avenir à long terme en définissant des prix et des quantités échangées différents suivant la structure qu'on lui donne. On conclura sur les conditions économiques du développement d'une pêche de grands pélagiques et de l'organisation d'un marché, ceci à partir des travaux de recherche et des études déjà réalisés. On indiquera quelles investigations doivent être menées pour compléter l'ensemble des éléments d'aide à la décision dans ce domaine. Pour effectuer cette évaluation, on a reconstituer des séries longues 1970-1986 (parfois avec des carences importantes) : celles-ci sont présentées en annexe.

Résumé : The green turtle (Chelonia mydas) is an emblematic species of marine life. However, nowadays it is subject to many threats (poaching, by-catch). Even if there is deep growing measures for its protection, the green turtle still is an endangered species and it is listed in Appendix I of Washington Convention (CITES). In order to elaborate efficient conservation and management plans, perfect knowledge of green turtle biology, but also of its population structure and their characteristics, are needed. In this thesis, we have assessed genetic structure of green turtle populations in the South-Western Indian Ocean by using genetic tools. In all, 1551 tissue samples have been collected from our study zone and from our control site French Polynesia (37 samples). All kinds if individuals were sampled (except males in reproductive phase) from 15 sampling sites including nesting, foraging, and immature development site. We used both control region of mitochondrial DNA and 6 microsatellite loci to better infer maternal and paternal lineages. We identified 29 haplotypes in the South-Western Indian Ocean. They are distributed in 3 independent and highly divergent clades, including one composed with haplotypes from Atlantic Ocean. For 7 of these haplotypes, it was the first time they were detected in the study zone. Fifteen haplotypes were previously undescribed, distributed in all the 3 clades. These new haplotypes seem to be specific to the South-Western Indian Ocean, which is then an original zone. Besides, we found a high allelic richness. These results show the South-western Indian Ocean is rich and very diversified. This region plays an important role in the global diversity of the species. The South-Western Indian Ocean is one of the two contact zones presently known between the two metapopulations of green turtles (Atlantic-Mediterranean and Indo-Pacific). This contact induces a genetic cline based on CM8 (Atlantic) and C3 (Indo-Pacific) haplotype frequencies. Analysis of the microsatellite differentiation between individuals provides evidence of genetic exchanges between the two metapopulations in the region. The South-Western Indian Ocean participates to green turtle global genetic mixing. Studying the influence of several intrinsic and extrinsic factors on population structuring provides useful information for management plan elaboration. We found no significant difference between genetic structures of foraging females and males, contrary to immature turtles which seem to be organised in 'regional pools'. This organisation could be due to both immature natal homing and influence of oceanic currents. High mitochondrial differentiation of nesting females and low global microsatellite differentiation of our samples indicate male-mediated gene flow among populations of the study zone. The genetic composition of a sampling site presents no significant variation along the year, even if we could notice some trends. Nevertheless, it can be significantly different from a year to an other one. This may result from alternation of distinct populations on the same site. We noticed different evolution in 10 or 20 years of the genetic composition depending on the sampling site. Geographic distance seems not to have significant influence on population structuring concerning microsatellite markers. Nesting females of Saziley Beach (Mayotte Island, Comoros Archipelago) present genetic divergence from females nesting in the two other sampled beaches of this island. The observed population structure shows no contradiction with the organisation of oceanic currents in the South-Western Indian Ocean. Comparing the results from the two genetic markers used, we identified 8 genetic differentiated clusters of turtles in the study zone and at least 6 distinct populations. These clusters constitute 8 potential management units (MUs) which could serve as basis in the elaboration of conservation and management plans.
La tortue verte (Chelonia mydas) constitue l'un des espèces emblématiques de la vie marine, pourtant de nombreuses menaces pèsent de nos jours encore sur sa survie (braconnage, captures accidentelles). Ainsi, malgré l'essor de mesures de protection menées à travers pour sa sauvegarde, la tortue verte constitue une espèce 'en danger d'extinction' et figure dans l'Annexe I de la Convention de Washington (CITES). Afin d'élaborer des plans de gestion et de conservation qui soient efficaces, il est important d'avoir une parfaite connaissance de la biologie de la tortue verte, mais aussi de la structure de ses populations et de leurs caractéristiques. C'est dans ce cadre que s'inscrit la présente étude. L'objectif de cette étude était d'acquérir des connaissances sur la structure des populations de tortues vertes dans le sud-ouest de l'océan Indien grâce à l'utilisation de l'outil génétique. Au total, 1551 échantillons de tissu ont été collectés dans la zone d'étude et dans notre site témoin la Polynésie française (37 échantillons). Toutes les catégories d'individus ont été échantillonnées (excepté les mâles en phase de reproduction) et les 15 sites d'échantillonnage comprennent à la fois des sites de ponte, d'alimentation et de développement pour les immatures. Deux types de marqueurs ont été utilisés : la région contrôle de l'ADN mitochondrial et 6 loci microsatellites, afin d'appréhender au mieux l'apport des lignées maternelles et paternelles. Nous avons pu mettre en évidence la présence dans le sud-ouest de l'océan Indien de 29 haplotypes distincts, appartenant à trois clades fortement divergents dont l'un constitué d'haplotypes originaires de l'océan Atlantique. Parmi ces haplotypes, 7 ont été détectés pour la première fois dans la zone d'étude, et 15 autres n'ont jamais été précédemment décrits chez cette espèce. Ils sont présents dans chacun des 3 clades d'haplotypes. Ces nouveaux haplotypes semblent spécifiques à la région, et en font une zone originale. On observe par ailleurs une grande richesse allélique dans les effectifs analysés. Ces résultats montrent que le sud-ouest de l'océan Indien est une zone riche et très diversifiée. Cette région joue un rôle important dans la diversité génétique globale de l'espèce. Le sud-ouest de l'océan Indien constitue l'une des deux seules zones connues à l'heure actuelle de contact entre les deux métapopulations de tortues vertes (Atlantique-Méditerranée et Indo-Pacifique). Ce contact a entraîné la formation d'un cline génétique portant principalement sur les fréquences relatives des haplotypes CM8 (Atlantique) et C3 (Indo-Pacifique). Les résultats obtenus lors de l'analyse microsatellite de la différenciation entre les individus originaires des deux métapopulations montrent que le sud-ouest de l'océan Indien constitue une zone d'échanges génétiques entre les deux métapopulations, participant au brasage génétique de l'espèce. L'étude de facteurs, intrinsèques et extrinsèques, pouvant influencer la structuration des populations apportent de nombreuses informations qui pourraient s'avérer utiles lors de l'élaboration de plans de gestion. La structure des femelles et des mâles en alimentation ne diffère pas, contrairement à celle des immatures qui semble s'organiser en 'pools régionaux' qui seraient le fruit de l'interaction d'un comportement de philopatrie et d'une influence des courants océaniques. La forte différenciation mitochondriale des femelles en ponte et la très faible différenciation microsatellite observée à l'échelle de la région, indiquent l'existence de flux de gènes via les mâles. La composition génétique d'un site ne varie pas de manière significative au cours de l'année. Par contre, elle peut varier d'une année à l'autre, signifiant l'alternance dans certains sites de ponte de plusieurs populations distinctes. L'évolution de la composition génétique d'un groupe, au cours de 10 ou 20 ans, diffère selon le site considéré. La distance ne semble pas influencer de manière significative la structuration des populations au niveau microsatellite. Les femelles en ponte sur la plage de Saziley (Mayotte) diffèrent génétiquement de celles pondant sur les deux autres plages de l'île. La structure observée des populations est en accord avec l'organisation des courants océanique dans la région. La confrontation des résultats obtenus à partir des deux marqueurs génétiques utilisés, permet la détermination de 8 ensembles génétiquement différenciés dans la zone d'étude et l'identification d'au moins 6 populations distinctes. Ces ensembles constituent autant d'unités de gestion (MUs) potentielles qui pourront servir de base à l'élaboration de plans de gestion et de conservation.

Résumé : International audience
Coral reef resource systems are complex adaptive social-ecological systems providing vital and valuableecosystem services for human societies such as food provision, coastal protection and recreational activities.Their sustainability is questioned in many places around the world as they experience combined effects ofmultiple chronic anthropogenic and natural drivers at local to global scales. From a management perspective,there is a crucial need to understand how the impact of these drivers cascade through the social-ecologicalsystem components. This study develops a transdisciplinary and participatory approach to investigating thesocial-ecological dynamics of a Polynesian coral reef coastal system. A preliminary conceptual model using theDriver-Pressure-State-Impact (DPSI) framework is first being built through participatory modeling workshops.Then, pressure-state relationships are assessed with the help of empirical datasets as a first step towards thevalidation of the DPSI model. Results shows striking social-ecological interactions with different patterns in thelagoon and in the fore reef. Local management should be: (1) less resource-focused to account more specificallyto the existing typology of actors; (2) more spatially-explicit to better distinguish management objectives andactions for the lagoon and the fore reef sub-systems; and (3) more coordinated with terrestrial agencies for acoherent land-sea connection and integration that would both (i) account for existing land-sea interactions and(ii) better reflect the Polynesian cultural heritage that considers nature from ridge to reef as a whole. Suchconceptual models of social-ecological systems are a useful tool to build exploratory scenarios to ultimatelysupport planning decision-making processes.
