Description : In the current ecological, economic and social context, the systematic use of drugs (prescription or self-medication) has direct health and environmental consequences. As a result, it is important to understand their perception by their main consumers. In this sense, social and environmental psychology aims to highlight the socio-psychological factors likely to influence the actors to adopt new practices or not (Zbinden et al., 2011). The present study, conducted in 2016 in CACEM territory, focuses on the analysis of social representations (SR) of drugs of the population from Martinique. The theory of SR allows the analysis of this mediation between man and his physical and social environment because these representations are highly contextualized and depend on the social anchoring of the groups (Doise, 1992).

Résumé : International audience
Understanding the factors underlying the spatio-temporal distribution of infectious diseases provides useful information regarding their prevention and control. Dengue fever spatio-temporal patterns result from complex interactions between the virus, the host, and the vector. These interactions can be influenced by environmental conditions. Our objectives were to analyse dengue fever spatial distribution over New Caledonia during epidemic years, to identify some of the main underlying factors, and to predict the spatial evolution of dengue fever under changing climatic conditions, at the 2100 horizon. We used principal component analysis and support vector machines to analyse and model the influence of climate and socio-economic variables on the mean spatial distribution of 24,272 dengue cases reported from 1995 to 2012 in thirty-three communes of New Caledonia. We then modelled and estimated the future evolution of dengue incidence rates using a regional downscaling of future climate projections. The spatial distribution of dengue fever cases is highly heterogeneous. The variables most associated with this observed heterogeneity are the mean temperature, the mean number of people per premise, and the mean percentage of unemployed people, a variable highly correlated with people's way of life. Rainfall does not seem to play an important role in the spatial distribution of dengue cases during epidemics. By the end of the 21st century, if temperature increases by approximately 3°C, mean incidence rates during epidemics could double. In New Caledonia, a subtropical insular environment, both temperature and socio-economic conditions are influencing the spatial spread of dengue fever. Extension of this study to other countries worldwide should improve the knowledge about climate influence on dengue burden and about the complex interplay between different factors. This study presents a methodology that can be used as a step by step guide to model dengue spatial heterogeneity in other countries.

Résumé : After a period of rapid development of the sites (an increase in both reared surface area and production), tropical shrimp aquaculture is currently being faced with critical problems due to economical and ecological constraints. In many countries with favourable conditions for shrimp aquaculture such as indonesia or Vietnam, sites are often badly selected and/or over-exploited. This conducts to sorne extent to decreases or collapses in the production due to the difficulty in predicting the maximum production capacity of the sites. Furthermore, it appears that production sustainability depends on many factors among which socio-economy and ecolo gy are of prime importance. The STD3 project titled « Assessment of tropical shrimp aquaculture impact on the environment in tropical countries using hydrobiology, ecology and remote sensing as helping tools for diagnosis )) was initiated in 1994, with the aim to study the sustainability of marine shrimp aquaculture in tropical areas, main! y Indonesia and Vietnam, through the following tasks: (i) improve site selection and study the impact of aquaculture on marine environments presenting a variable sensitivity to organic sewage, (ii) analyse the socio-economical aspects and profitability of the aquaculture industry and of common resources (iii) use remote sensing and geographical data bases for diagnosis and monitoring of site degradation (iv) reinforce the capacity of Asian scientists through training. Severa! aquaculture sites have been investigated in the Lampung region (South Sumatra, Indonesia), the Mekong delta (Vietnam) and on the West coast of New-Caledonia, providing a large range of typical ecosystems encountered in Asia and in the Pacifie, from coralline sites to coastal plains with mangrove and deltaic areas. The study concerned the spatial structure and seasonal influence of these ecosystems, the temporal variation during the course of the project (3 years) and the relation between the ecological structure and farm productions. Remote sensing provides a synoptic vision over large land expanses. Severa! scenes were processed for landuse mapping using conventional classification techniques. Concerning water quality assessment, a general relation for the Java sea was found between image and field data in terms of total suspended matter. Applying this relation to a new site in Sumatra has provided an initial approach to water type and, together with land use mapping, a preliminary assessment of the suitability of the area to shrimp aquaculture development. Socio-economic research has been focused on the identification ofneeds for collective action, including public policy, in the perspective of shrimp farming sustainability. The main concern is in the regulation of shrimp farming intensification and extensification at the scale of coastal ecosystemic entities in a common property resource management perspective. The common considered here is coastal water quality. Comparing the local development profiles and the institutional grounds for the design and implementation of collective management rules shows that variables such as land tenure system, farm owner socio-economic profile, social homogeneity or heterogeneity of the farmers are key factors to analyse the potential for sustainability. The defmition of water quality and the possible means to ensure its collective management are discussed. The main conclusion is that the economie incentives to farming development are strong but there is no significant difference among traditional, semi-intensive and intensive systems in terms of economie efficiency or wealth distribution. The description of the functioning of the different kinds of ecosystems make it possible to give an advice concerning the positioning of the activity inside the ecosystem, and furthermore to have a reference state in order to determine the impact of the activity on the coastal environnement. This impact can be summarized as an increase in the concentration of total suspended matt€?r, of particulate organic matter and of sulfate reducing bacterias. This organic ma~.er is either issued from rearing activities or from telluric origine, due to mangrove eradication when building the ponds. An evaluation of the relationship existing between productivity and characteristics of each ecosystem bas been conducted by correlating ecological indicators data (concentration of total suspended matter, particulate organic matter, chlorophyll, percentage of pheopigments in total pigments and cyanobacteria and sulfatereducing bacteria in water and sediments) with the average production of the farms. This comparison lead to the compilation of a scale of observed production integrating the range of these environmental parameters with shrimp production levels, bound to facilitate the positioning of shrimp farming in relation with the confmement leve! of each ecosystem. Lastly, ali geographie data originated from the various compartments of the study have been geo-referenced and loaded into a geographical information system. This allows to display any query made on spatial variables and their related statistical data, including the ir variations over the last few years and to reveal patterns and phenomena otherwise not obvious.
Le programme mis en oeuvre par la DRV (Paris, CREMA-L'Houmeau, DELIAO Brest, COP Tahiti, GIE/RA Nouvelle Calédonie), dans le cadre d'un projet européen STD3 «(Sciences et Technique au Service du Développement», en collaboration avec l'Université de Montpellier II, l'Ecole Nationale d'Agronomie de Rennes, l'ITC (Hollande), l'Institut Océanographique de Nha Trang (Vietnam), le BADC de Jepara et le BPPT de Jakarta (Indonésie), avait pour but la mise au point de méthodes permettant d'améliorer la sélection des sites ainsi que le suivi du développement et de l'impact de l'aquaculture des crevettes Péneides en milieu tropical pour éviter la surexploitation. Quatre axes de recherche ont été défmis : a) identifier la nature et quantifier les rejets de déchets issus de ce type d'aquaculture, b) définir les caractéristiques écologiques des écosystèmes susceptibles d'accueillir l'activité aquacole et suivre leur évolution sous l'influence des rejets, c) déterminer l'influence de la gestion des fermes et des ressources (aspects économiques) sur les performances de productivité, d) déterminer la capacité de la télédétection comme outil de diagnostic d'impact à l'échelle de la région, e) mener un programme de formation d'étudiants et jeunes chercheurs Vietnamiens et Indonésiens.

Résumé : International audience
BACKGROUND: Few studies have explored how noise might contribute to social health inequalities, and even fewer have considered infant mortality or its risk factors as the health event of interest.In this paper, we investigate the impact of neighbourhood characteristics - both socio-economic status and ambient noise levels - on the spatial distribution of infant mortality in the Lyon metropolitan area, in France. METHODS: All infant deaths (n = 715) occurring between 2000 and 2009 were geocoded at census block level. Each census block was assigned multi-component socio-economic characteristics and Lden levels, which measure exposure to noise. Using a spatial-scan statistic, we examined whether there were significant clusters of high risk of infant mortality according to neighbourhood characteristics. RESULTS: Our results highlight the fact that infant mortality is non-randomly distributed spatially, with clusters of high risk in the south-east of the Lyon metropolitan area (RR = 1.44; p = 0.09). After adjustments for socio-economic characteristics and noise levels, this cluster disappears or shifts according to in line with different scenarios, suggesting that noise and socio-economic characteristics can partially explain the spatial distribution of infant mortality. CONCLUSION: Our findings show that noise does have an impact on the spatial distribution of mortality after adjustments for socio-economic characteristics. A link between noise and infant mortality seems plausible in view of the three hypothetical, non-exclusive, pathways we propose in our conceptual framework: (i) a psychological pathway, (ii) a physiological disruption process and (iii) an unhealthy behaviours pathway. The lack of studies makes it is difficult to compare our findings with others. They require further research for confirmation and interpretation.

Résumé : International audience
Mount Pinatubo volcano erupted in June 1991 in the main island of Luzon belonging to the Philippines archipelago. Huge economic losses and population exodus have followed. This major crisis has been relayed with other crises due to rainfed lahars which have been supplied with eruption deposits. These lahars have occurred every year since 1991 during the rainy season. They will probably last until 2005. After a brief presentation of the Philippine official response system to disasters, this paper draws up a critical analysis of the different kinds of institutional and social responses deployed to manage the different crisis and post-crisis phases of this event. Based on three viewpoints: from population, media and other actors, this analysis attempts to point out the strengths and weaknesses of the official management system, especially by studying the efficiency and the range of the solutions taken. So, it appears that the management of the June 1991 main crisis (eruption) was a success. On the other hand, difficulties have occurred with lahars risk management. Indeed, these lahars have obliged the authorities to protect and relocate thousands of people. In spite of persistent problems, the management system (monitoring/warning/evacuation) of lahar crises improves year after year. Failures appear especially within the rehabilitation program (protection/rehousing). Many direct (lack of means, preparedness, coordination, dialog,
etc.) and indirect (politico-administrative, socio-economic, cultural contexts) factors come together to lock the wheels of
the institutional response system. They defer the socio-economic start of this vital northern Philippines area.

Résumé : The stock of Lambi, Strombus gigas (gastropod: strombidae), coastal benthic resource, has been exploited artisanally since the prehistoric period in Martinique. Nowadays, three lines of work exploit the species: free diving, nets (since the middle of the century) and scuba diving since 1985. This report presents the activity of each line of work, surveyed directly from 1986 to 1987: fishing zones and resource allocation, production, effort and performance, detail of catches (by length). The socio economic characteristics of the lambi fishermen are studied. The significant production of leisure fishing is also estimated. The decrease in the production and performance, as well as the lowering of the size of the first catch for about thirty years show that the stock is overexploited. The biological phenomenon of the stock: growth of the shell (length and shell lip), growth in weight, acquiring of sexual maturity, natural mortality are studied. The factors of mortality through fishing are estimated by class of length for the current exploitation regime by pseudo-cohort analysis. If the results confirm that the stock is overexploited, the level of overexploitation of the stock cannot be specified because of the presence of a number of lipped adults not yet too exploited in water deeper than 20 metres. The analysis of the dynamic process of the exploited population indicates two ways to the production of the stock: the forcing of the recruitment and the regulation of the exploitation regime. The lack of economic profitability of the production of juveniles over 30 mm and the difficulties raised by their collection in their natural habitat lead to the rationalization of the exploitation. The production and performance (by recruits) simulations performed for different exploitation regimens indicate that the only two conceivable options are the introduction of a minimum catch size, i.e. lambi with forming lip, and the regulation of the fishing effort. The socio-economic implications of the introduction of the determined management measures show that their applicability level is very low, because of the Martinique fishermen polyactivity, their low socio-economic level and mostly because of the free access to the resource. As a consequence, it is suggested to create new professional structures with a wide jurisdiction, in order to locally manage the marine areas, their use and their resources. (unverified OCR)
Le stock de lambi, Strombus gigas (gastéropode: strombidae), ressource benthique côtière, est exploitée artisanalement depuis l'époque préhistorique en Martinique. Trois métiers exploitent actuellement l'espèce: plongée libre, filets (depuis le milieu du siècle) et plongée en scaphandre autonome depuis 1985. Ce rapport présente l'activité de chaque métier, suivie de 1986 à 1987 par une enquête directe: zones de pêche et allocation de la ressource, productions, efforts et rendements, composition en longueur des captures. Les caractéristiques socioéconomiques des pêcheurs de lambi sont étudiées. La production d'une pêche plaisancière non négligeable est estimée. La diminution de la production, des rendements et l'abaissement de la taille de première capture depuis une trentaine d'années révèlent que le stock est surexploité. Les phénomènes biologiques du stock: croissance de la coquille (longueur et pavillon), croissance en poids, acquisition de la maturité sexuelle, mortalité naturelle sont étudiés. Les coefficients de mortalité par pêche sont estimés par classe de longueur pour le régime d'exploitation actuel par l'analyse de pseudo-cohorte. Si les résultats confirment l'état surexploité du stock, le niveau de surexploitation ne peut être précisé en raison de l'existence d'adultes pavillonnés encore peu exploités sur les fonds de plus de 20 mètres. L'analyse des processus dynamiques de la population exploitée indique deux voies pour restaurer la production du stock: le forçage du recrutement et la régulation du régime d'exploitation. Le manque de rentabilité économique de l'élevage des juvéniles au-delà de 30 mm et les difficultés pour leur collecte dans le milieu naturel conduisent à rechercher la rationalisation de l'exploitation. Les simulations de la production et du rendement par recrue réalisées pour différents régimes d'exploitation indiquent que seule la mise en place d'une taille minimale de capture, i.e le lambi au pavillon en formation, et une régulation de l'effort de pêche sont envisageables. Les implications socio-économiques de la mise en oeuvre des mesures de gestion déterminées montrent que leur niveau d'applicabilité est très faible, en raison de la polyactivité des pêcheurs martiniquais, de leur faible niveau socioéconomique et surtout, du régime de libre accès à la ressource. Aussi, il est proposé la création de nouvelles structures professionnelles aux compétences larges, qui permettraient, pour chacun des bourgs, une gestion locale de l'espace marin, des usages et des ressources.

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 : International audience
As climate change continues to impact socio-ecological systems, tools that assist conservation managers to understand vulnerability and target adaptations are essential. Quantitative assessments of vulnerability are rare because available frameworks are complex and lack guidance for dealing with data limitations and integrating across scales and disciplines. This paper describes a semi-quantitative method for assessing vulnerability to climate change that integrates socio-ecological factors to address management objectives and support decision-making. The method applies a framework first adopted by the Intergovernmental Panel on Climate Change and uses a structured 10-step process. The scores for each framework element are normalized and multiplied to produce a vulnerability score and then the assessed components are ranked from high to low vulnerability. Sensitivity analyses determine which indicators most influence the analysis and the resultant decision-making process so data quality for these indicators can be reviewed to increase robustness. Prioritisation of components for conservation considers other economic, social and cultural values with vulnerability rankings to target actions that reduce vulnerability to climate change by decreasing exposure or sensitivity and/or increasing adaptive capacity. This framework provides practical decision-support and has been applied to marine ecosystems and fisheries, with two case applications provided as examples: (1) food security in Pacific Island nations under climate-driven fish declines, and (2) fisheries in the Gulf of Carpentaria, northern Australia. The step-wise process outlined here is broadly applicable and can be undertaken with minimal resources using existing data, thereby having great potential to inform adaptive natural resource management in diverse locations.

Résumé : The literature has identified a set of factors explaining the accumulation of capital. However, little attention has been paid to the impact of cultural beliefs. This paper, based on economic science, uses data collected from 207 haitian formal sector firms to develop and test a model of capital accumulation integrating socio-cultural traits, including life in the present moment, fatalism, primacy of the hereafter and mutual assistance. The results reveal that the primacy of the beyond, life in the present moment and mutual aid have negative and significant impacts on accumulation of capital. And, fatalism has positive and significant effects on this variable.
La littérature a identifié un ensemble de facteurs expliquant l'accumulation du capital. Cependant, les travaux ne se sont que très peu intéressés à l'impact des croyances culturelles. Ce papier, relevant de la science économique, utilise des données collectées auprès de 207 entreprises du secteur formel haïtien pour élaborer et tester un modèle d'accumulation du capital intégrant des traits socioculturels, notamment la vie dans l'instant présent, le fatalisme, la primauté de l'au-delà et l'entraide mutuelle. Les résultats révèlent que la primauté de l'au-delà, la vie dans l'instant présent et l'entraide mutuelle ont des impacts négatifs et significatifs sur l'accumulation du capital. En revanche, le fatalisme a des effets positifs et significatifs sur cette variable. Mots clés. Accumulation du capital, croyances, traits socioculturels.

Résumé : International audience
Background Although the French eating model may differ from those of other countries, no studies to date have investigated dietary patterns in a wide age range of adults and at the national level. We aimed to identify dietary patterns (DP) of French adults and assess their associations with demographic, socio-economic and behavioural factors. Methods The present study included 2624 adults (1087 men, 1537 women) aged 18–79 years from the cross-sectional national French INCA2 dietary survey. Dietary data were collected using a 7-day estimated food record. Clusters of DP were derived using principal component analysis and clustering, conjointly. Age-adjusted logistic regression analyses were used to investigate the association between DP and correlates. Results Five DP were identified, namely ‘traditional’, ‘prudent’, ‘diversified’, ‘processed’ and ‘sandwiches’. Men were more likely to follow a traditional diet and women the ‘prudent’ pattern. Members of the ‘processed’ and ‘sandwiches’ patterns were younger compared to non-members. Healthier dietary patterns were overall positively associated with a higher socio-economic position, healthier behaviours (in terms of sedentary behaviours and smoking status) and lower body mass index. Under-reporting of energy intake, restrictive diet to lose weight and dietary supplement consumption were also related to specific DP, although differentially in men and women. Associations with contextual factors (i.e. household composition, agglomeration size and region) were also observed. Conclusions The identification of adults’ dietary patterns and associated behaviours (all modifiable) is important for the conceptualisation of multi-behavioural programs. The additional information on social and environmental correlates is also essential for targeting the most vulnerable population groups in the context of such public health interventions

Résumé : International audience
The international symposium on «Urban Growth and Natural Hazards, in particular in Developing Countries» was held in the University Blaise Pascal, Clermont-Ferrand (France) on December 2 and 3, 1994. This meeting brought together about 70 research people, Ph.D. students, and professionals from France and 12 countries, representing universities, research agencies, as well as government and private companies. The symposium aimed to gather specialized people who are engaged and acting in programmes on hazard appraisal, risk prevention and urban management in city environment. These people aimed to compare experiences acquired in two different fields: on the one hand urban growth and its consequences, and on the other hand, natural hazards and effects, in particular in Developing Countries.Half-way through the International Decade for Natural Hazard Disaster Reduction, we strove to reconcile two points of view usually distincts: nature-oriented research and society-oriented research on hazards. These convergent approaches should merge, not only to improve knowledge of natural hazards and risks, but also to cope with hazard and risk situation on a day-basis in a city. We also choose to study both approaches in Developing Countries (DC) because most of the large cities of the world already are or will be located there in near future. In addition, city location in DC coincides with tropical areas where natural hazards are most frequent threats to life, in particular in mountains, on seashores, and on active convergent plate margins. We stress the fact that the 3 following topics are often lacking in studies which have been carried out on natural hazard appraisal and management. 1) How should we include social and economical factors, and particularly a sound analysis of vulnerability of people and values at risk ? 2) How should we cope with hazard management in large cities of Developing Countries ? 3) What is the specific task of research people in hazard case studies engaged in urban environment and management?Three themes correspond to the three sessions of the symposium. (1) Natural hazards and environmental factors : inventory, diagnostic and classification, (2) Vulnerability of urban society and environment : concepts, approaches, and classification, (3) Tools for urban risk prevention and risk management in case of crisis and catastrophes.
Ce numéro de la Revue de Géographie Alpine reprend une dizaine parmi les 41 contributions exposées par des chercheurs français et étrangers lors du colloque international « Croissance urbaine et risques naturels dans les pays en développement » qui s'est déroulé à l'Université Blaise Pascal, Clermont-Ferrand, les 2 et 3 décembre 1994. L'objectif général du colloque était de rassembler les diverses compétences existant en France et à l'étranger dans le domaine de l'évaluation et de la gestion des risques naturels et de confronter les expériences acquises à l'interface entre les villes en croissance et le champ d'action des phénomènes naturels créateurs de risques. Le colloque a donc réuni des chercheurs, des doctorants et des praticiens français et leurs collègues étrangers chargés de prévention, de gestion des risques naturels et de gestion urbaine, principalement dans les grandes villes des pays en développement (P.E.D.).Parvenus à mi-chemin de la Décennie Internationale pour la Prévention des Catastrophes Naturelles, nous avons porté des regards croisés sur les approches naturalistes et sociologiques des risques naturels. Il est maintenant nécessaire de faire converger ces approches, non seulement dans la connaissance des menaces et des risques, mais dans la gestion du risque quotidien en milieu urbain. Nous avons concentré ces approches dans les pays en développement ; en effet, le site de leurs grandes villes coïncide souvent avec le champ d'action des phénomènes naturels générateurs de risques, notamment dans la zone intertropicale et en particulier dans les marges continent ales actives (par exemple autour du Pacifique).Nous avons porté l'accent sur 3 points principaux, qui semblent en partie faire défaut dans les études et les méthodes actuellement mises en oeuvre dans la gestion des risques naturels : 1) comment prendre en compte les aspects socio-économiques, en particulier les types d'analyse des vulnérabilités ? 2) comment aborder la gestion des risques en milieu urbain dans les P.E.D. ? 3) quel rôle doit jouer le chercheur en Sciences de l'Homme, de la Société et de la Terre dans les analyses, les expertises consacrées aux risques et surtout dans leur gestion globale, à la charnière des sociétés citadines précaires et des milieux « naturels » contraignants ?Les contributions ont été regroupées, exposées et discutées lors du colloque sous forme de 3 thèmes. (1) Les phénomènes naturels créateurs de dommages (= menaces) : diagnostic, inventaire et typologie, (2) Les vulnérabilités des sociétés et des espaces urbanisés : concepts, typologie et modes d'analyse, (3) Les outils d'aide à la prévention et à la gestion du risque en milieu urbain.

Résumé : International audience
The article deals with the intercultural exchanges between two cultural movements rooted in the African Diasporas. In Guadeloupe, a French island in the Caribbean, Gwo-ka was born on the plantation in the 17th century. Blues appeared in the southern United-States by the end of the 19th century. In order to illustrate the similarities between these two afro-diasporic cultural phenomena, the article first examines the economic and social factors that prompted their emergence. Second, it compares their socio-cultural functions within their respective communities. Using Paul Gilroy’s theory of the Black Atlantic, the article concludes with a questioning of his thesis within the framework of the present study.
L’article s’intéresse à l’interculturalité entre deux phénomènes culturels que sont le Gwo-ka et le Blues issus de la diaspora africaine aux Amériques. Le Gwo-ka est une expression culturelle née en Guadeloupe, île française située dans la mer des Caraïbes. Le Blues est également une expression culturelle née dans le Sud des États-Unis. À partir de l’analyse de leur « matrice » sociohistorique, il s’agira de mettre en évidence les rapprochements entre les différentes fonctions socioculturelles. Nous tenterons de comprendre si la théorie de l’Atlantique Noir de Paul Gilroy, reliant les communautés afro-diasporiques du Nouveau Monde, est valable dans le cadre de notre sujet d’étude.

Résumé : El turismo náutico se concibe como un segmento estratégico para el desarrollo turístico de España y sus destinos costeros. En Canarias existe una apuesta pública por la especialización del Archipiélago y su reposicionamiento como destino líder europeo de escala en el Atlántico, por las múltiples cualidades naturales que posee la región para el deporte náutico, y su posición geográfica estratégica en el cruce desde Europa hacia el Caribe. Así, se viene planteando una renovación y desarrollo del sector de la náutica de recreo y el turismo de yates, con estrategias enfocadas a la diversificación y el crecimiento. Los altos costes sociales y medioambientales asociados a este tipo de desarrollo justifican la necesidad de una mayor atención académica, que permita comprender las particularidades y complejidades de la actividad y este mercado turístico. En la misma medida en que esta actividad es vista como un factor de riesgo para el medioambiente, la comunidad local y la franja litoral, también son crecientes las preocupaciones y sensibilidad por parte de los turistas hacia estos fenómenos. Dada la carencia de investigaciones en el área, este estudio se propone identificar los determinantes de la satisfacción de los navegantes europeos con los puertos de escala de Canarias. Como resultado de encuestar a 185 navegantes europeos durante su escala en seis puertos deportivos del archipiélago en 2014 y 2015, y la validación de un sistema de ecuaciones estructurales, se ha podido demostrar, entre otros aspectos, que existe una predilección en el mercado de navegantes europeos por presenciar esfuerzos y políticas de gestión ambiental sostenible en las marinas, siendo éste un factor determinante de su satisfacción. Los hallazgos permiten elaborar una serie de recomendaciones a gestores y operadores turísticos del sector, en aras de contribuir al diseño de estrategias que garanticen un desarrollo más sostenible y razonable de la actividad, basados en el efecto positivo que producen estas estrategias en la demanda, y el potencial valor de diferenciación turística que otorga, en el entorno competitivo del sector.
The nautical activiity has great potential for the socio-economic development of tourism. In Spain, the sector is a priority concern, especially for the Canary Islands, which show a clear commitment to specialise and reposition the destination as a top quality nautical destination on a European level. These aspects, together with the prior experience and tradition these islands have as a stopover destination for vessels in the Atlantic, when crossing Europe towards the Caribbean, represent strengths that have not yet been taken advantage of in the archipelago’s attempt to move away from its image as a traditional sun and beach destination. The Governmental Authorities in the Canary Islands have clear strategies in place to promote the yachting tourism growth. However, renewing the sector is believed to be a difficult process because of the large number of factors that interact within the same. This is a phenomenon of sufficient social and environmental significance to justify academic attention. This research analyses therefore the determinants of the European yachtsmen´s satisfaction with the ports of call of the Canary Islands. Data results of questioning 185 European yachtsmen crossing the Atlantic during 2014 and 2015 reveal that, among other aspects, proper environmental management of marinas leads to an increasing yachtsmen´s satisfaction. The findings provide the opportunity for developing recommendations for tourism managers and practitioners, in the attempt to contribute to a more sustainable and reasoned development and growth in the sector. Based on the current preferences of the European market of yachtsmen, it is possible to assure that environmental and social responsibility policies are a key differentiation factor for the competitiveness of the sector.

Résumé : International audience
Background - Several studies have investigated the implication of biological and environmental factors on geographic variations of end-stage renal disease (ESRD) incidence at large area scales, but none of them assessed the implication of neighbourhood characteristics (healthcare supply, socio-economic level and urbanization degree) on spatial repartition of ESRD. We evaluated the spatial implications of adjustment for neighbourhood characteristics on the spatial distribution of ESRD incidence at the smallest geographic unit in France.Methods - All adult patients living in Bretagne and beginning renal replacement therapy during the 2004–09 period were included. Their residential address was geocoded at the census block level. Each census block was characterized by socio-economic deprivation index, healthcare supply and rural/urban typology. Using a spatial scan statistic, we examined whether there were significant clusters of high risk of ESRD incidence.Results - The ESRD incidence was non-randomly spatially distributed, with a cluster of high risk in the western Bretagne region (relative risk, RR = 1.28, P-value = 0.0003). Adjustment for sex, age and neighbourhood characteristics induced cluster shifts. After these adjustments, a significant cluster (P = 0.013) persisted.Conclusions - Our spatial analysis of ESRD incidence at a fine scale, across a mixed rural/urban area, indicated that, beyond age and sex, neighbourhood characteristics explained a great part of spatial distribution of ESRD incidence. However, to better understand spatial variation of ESRD incidence, it would be necessary to research and adjust for other determinants of ESRD.

Résumé : International audience
The principal gynaecological cancers (breast, ovary, uterus, and cervix) account for over 40% of cancers found in women worldwide. However, large differences exist, in both their incidence and geographical distribution. The French West Indies, through their location, environment, socio-economic development, lifestyle, nutrition and the origins of their populations, constitute territories with a very particular character in the heart of the Caribbean. These characteristics have an impact on public health and can affect the incidence of tumours. We report for the first time the incidence of these major gynaecological cancers in Guadeloupe. Breast, ovary and uterine cancers have lower incidences in Guadeloupe than in mainland France. By contrast, cervical cancer is more frequent in Guadeloupe than in mainland France. The mortality rates associated with breast cancer, ovary and uterine cancer are also lower in Guadeloupe than in mainland France, whereas the opposite pattern is observed for cervical cancer. These observations may be accounted for in part by a difference in the prevalence of established or suspected risk factors for each of these types of cancer.

Résumé : Coral reefs are amongst the richest and more emblematic ecosystems of the world. These hotspots of biodiversity provide many services to Human societies, bringing leisure and economic added values. In many areas, especially developing countries, these ecosystems are submitted to both climate change (rise of sea temperature and level, acidification) and human coastal pressures (urbanisation, resources exploitation). In this context, an increasing number of Marine Protected Areas is settled on coral reefs environments in order to ensure their conservation and to mitigate local pressures. Hence, one of MPAs Managers' missions is to bring ecological and social data together to build integrated indicators of effectiveness. In Reunion Island, a MPA called the Marine reserve of La Réunion was settled in 2007 along a densely urbanised and populated fringing reef coast. In order to better evaluate its MPA effectiveness, the manager requires the integration of social stakes to the management plan. A uses monitoring protocol was developed in this purpose using an ultra light aircraft and a camera. Data on 15 different recreational and non-recreational uses were acquired between 2010 and 2013, flying 48 times a year, and entered into a Geographic Information System. A huge resulting database allowed the building of an initial knowledge of the spatio-temporal distribution of uses within the Reserve. It also enabled the analysis of the uses' evolution regarding various factors of variations (amenities, facilities, shark attacks, tourism, etc.). Finally, we assessed the contribution to management efficiency using social indicators (governance, pressure indicators), and to interdisciplinary research in bringing ecologic and uses data together. This thesis brings a brand new information about coastal human activity and spatio-temporal dynamics of direct pressures on reef. This tool, designed to be reproducible and cost-optimized, enables the production of a set of indicators. Its integration to the management plan exclusively depends on the strategic choices of the manager.
Les récifs coralliens figurent parmi les biomes côtiers les plus emblématiques de la planète. Ces points chauds de la biodiversité mondiale sont convoités par les sociétés humaines pour leurs qualités paysagères et leur plus-value économique. Exposés au même titre que de nombreux écosystèmes côtiers aux changements climatiques (élévation de la température, acidification des océans), ils sont de toutes parts soumis à une anthropisation littorale mal maitrisée (urbanisation, surexploitation des ressources). Dans ce contexte, de plus en plus d' Aires Marines Protégées (AMP) s'établissent sur des écosystèmes anthropisés, les amenant à intégrer l'Homme au coeur de la gestion. À La Réunion où l'urbanisation littorale est dense et où le paysage des usages littoraux ne cesse de s’étoffer, une Réserve Naturelle Marine (RNMR) a été établie en 2007 sur un récif frangeant. L’évaluation de l’efficacité de cette AMP par son gestionnaire doit se faire par le biais d'un ensemble d'indicateurs écologiques et socio-économiques. C’est en vue d’apporter des connaissances sur la fréquentation et les usages pratiqués au sein de la RNMR que cette thèse a été initiée. Elaboré sur la base d'un suivi en ULM, un protocole a été reproduit chaque année entre 2010 et 2013 et a permis la constitution d'une base de données spatialisée, dont l'exploitation a produit trois types de résultats: i) une connaissance initiale de la répartition spatio-temporelle des usages au sein de la RNMR; ii) une compréhension de l'évolution des dynamiques spatio-temporelles à la lumière des facteurs de variations identifiés (aménagements, aménités, crise requin, tourisme, etc.), et iii) une contribution à la gestion par le développement d'indicateurs sociaux (gouvernance, pressions), et à la recherche interdisciplinaire par une confrontation des données de fréquentation et des données écologiques du milieu. La réflexion menée dans le cadre de cette thèse apporte un éclairage nouveau sur les usages et la fréquentation des littoraux coralliens à La Réunion, et leur traduction en termes de pression anthropique directe. Pensé pour être reproductible et optimisé en termes de coût, cet outil permet la production d’un ensemble d’indicateurs dont l’intégration au plan de gestion dépend exclusivement des choix stratégiques du gestionnaire.

Résumé : El turismo es una necesidad para todas las naciones, ya que genera ingresos, empleos, es una fuente de entrada de divisas que permite equilibrar la balanza de pagos de diferentes economías, entre otros factores. Pero junto con ello es fuente de profundas desigualdades y de impactos socio-ambientales considerables en naciones menos desarrolladas del mundo. El impulso a proyectos de Turismo Alternativo en el estado de Chiapas de la república mexicana es importante, ya que en esa entidad perviven muchas comunidades mayas con historia y sabiduría ancestral, acercarse a los postulados bajo los cuales deben construirse proyectos alternativos es punto central de este trabajo para también documentar los posibles impactos a futuro que pueden presentarse.
The tourism is a need for all the nations, since it generates income, work places, it is a source of entry of currencies that allows to balance the balance of payments of different economies, between other factors. But together with it there is source of deep inequality and of impacts an associate environmental considerable in less developed nations of the world. The impulse to projects of Alternative Tourism in the state of Chiapas of the Mexican republic is important, since in this entity many Mayan communities survive with history and ancestral knowledge, to approach the postulates under which alternative projects must be constructed is a central point of this work also to document the possible impacts to future that can appear.

Résumé : International audience
The socio-economic status (SES) of populations has an influence on the incidence or mortality rates of numerous health outcomes, among which respiratory diseases (Prescott et al., 2003; Ellison-Loschmann et al., 2007). Considering asthma, the possible contribution of SES to overall prevalence –regardless of asthma severity-, remains controversial in industrialized countries. Several studies indicate that allergic asthma is more prevalent in more well-off populations whereas the non-allergic forms of asthma are more common in the deprived ones (Cesaroni et al., 2003; Blanc et al., 2006). On the other hand, severe asthma whatever its etiology appears to be more frequent in the latter populations, as compared to the more affluent (Basagana et al., 2004). Risk factors for exacerbations (e.g., passive smoking (Wright Subramanian, 2007), psychosocial stress (Gold & Wright, 2005), cockroach allergens (Kitch et al., 2000), and suboptimal compliance with anti-inflammatory medication (Gottlieb et al., 1995)) are generally more common among people with asthma and low SES than their better-off counterparts. These observations support the hypothesis that some factors more present in deprived populations contribute to asthma exacerbation (Mielck et al., 1996).

Résumé : Dans le cas des DOM, singulièrement la Guadeloupe, qui sont à l'aube de l'expérimentation de réformes profondes de politiques économiques, l'élaboration d'un outil de simulation macroéconomique tel qu'un MEGC apparaît naturellement comme une exigence plus que souhaitable. Ce recours à la construction de modèles spécifiques pour les DOM est en parfaite cohérence avec l'une des principales conclusions du rapport d'information diligenté par le Sénat aux lendemains de la crise sociale du début de l'année 2009. Les appels à projet de la Commission europèenne et du Ministère de l'Outre-mer vont justement dans le sens de pallier celte carence puisque la politique économique des RUP de façon générale est conduite à vue sans aucun outil d'investigation ex ante. Nous avons conçu plusieurs modèles. Parmi eux, CloDyn est le premier modèle macroéconomique pour les DOM à vocationopérationnelle. Composée de plus de 2000 équations, ce modèle d'équilibre général calculable tient compte de nombreuses rigidités sur les marchés des biens et services et du travail et se décline sous deux versions: statique et dynamique. Les élasticités ont fait l'objet d'estimations économétriques. Il tient compte de nombreuses spécificités tant au niveau de la fiscalité de ces régions (octroi de mer, taxe sur les carburants, subventions à l'exportation) que du coût des facteurs (exonérations des charges sur les bas salaires, sur rémunératio des fonctionnaires). Il repose sur une formalisation des mécanismes en oeuvre dans ces économies que nous avons appelé le DOM disease pour expliquer les dysfonctionnements persistants sur le plan macroéconomique.
In the case of the French overseas regions, particularly of Guadeloupe, which are just beginning to experiment with economic policies radical reforrns, the development of a macroeconomic simulation tool such as a CGE model appears naturally as a highly desirable requirement. The use of the construction of specifie models for DOM is fully consistent with a major finding of the report commissioned by the Senate in the aftermath of the social crisis of the early 2009. As a malter of facts, the purpose of the calls for project initiated by the European Commission and the Ministry of Overseas is to remedy this deficiency, since the RUP economie policy is generally to conduct no investigation tool ex ante. We designed several models. Among them, CloDyn is the first operational DOM-based macroeconomic rnodel. Composed of more than 2000 equations, this computable general equilibrium model takes into account many rigidities in the markets for goods and services and labor and is available in two versions: static and dynamic. Elasticities have been econometrically estimated. lt rests on many features of both taxation (dock dues, fuel tax, export subsidies) and the cost factors (exemption from charges on low wages, remuneration of civil servants). Il is based on a formalization of the mechanisms at work in these economies we calied the DOM disease to explain the persistent failures in such economies. lt also evaluates the monetary poverty among households with the use of a block of microsimulation model and we allow a profane in GAMS to use this tool and conduct its own analytical work thanks to a user friendly interface.
