Description : The import data from the Ministry of Trade indicates that Suriname has increased pesticides imports over the last five years. According to research evidence, as much as 80% of potential production in various crops including rice would be lost as a result of agricultural pests without crop protection measures. Even though the benefits of chemical pesticides use are clear, negative health and environmental impacts of their use are also evident. In lieu of this information a study was conducted to determine small rice farmers? perceptions on their knowledge of pesticide use, and safety of pesticides in rice production For this investigation a questionnaire was adapted from a pesticide use survey to generate and collect meaningful data on perceptions of small rice farmer?s knowledge and practices related to pesticide use and safety aspects in rice production in Nickerie. The sample population consisted of 200 small rice farmers.?The collected data was analyzed using SPSS and Microsoft Excel. Descriptive statistics and correlation were used to describe the data. Findings reveal that the rice farmers are male, on the average older than 50 years and have more than 15 years of experience with rice production. Results also reveal that farmers perceive the recommended dosage as too little and therefore increase the dosage. They often mix different types of pesticides and do not use all of their protective equipment while spraying. Based on the results it is recommended to develop pesticide policies to stimulate farmers to practice safe pesticide use in Suriname. Les données d'importation du ministère du commerce indiquent que le Surinam a augmenté des importations de pesticides au cours des cinq dernières années. Selon des preuves de recherches, pas moins de 80% de production potentielle dans diverses cultures comprenant le riz serait perdu en raison des parasites agricoles sans mesures de protection des cultures. Quoique les avantages d'une utilité chimique de pesticides soient clairs, la santé et les impacts sur l'environnement négatifs de leur utilisation est également évident. Au lieu de cette information une étude a été entreprise pour déterminer les perceptions des petits agriculteurs de riz sur leur connaissance d'utilisation de pesticide, et la sécurité des pesticides dans la production de riz. Pour cette enquête un questionnaire a été adapté d'une enquête d'utilisation de pesticide pour se produire et rassembler des données significatives sur des perceptions de la connaissance du petit agriculteur de riz et des pratiques s'est rapporté aux conditions de sécurité d'utiliser-et de pesticide dans la production de riz dans Nickerie. La population témoin s'est composée de 200 petits agriculteurs de riz. Les données rassemblées ont été analysées utilisant SPSS et Microsoft Excel. Des statistiques descriptives et la corrélation ont été employées pour décrire les données. Les résultats indiquent que les agriculteurs de riz sont masculins, les plus vieux que 50 années moyennes et ont plus de 15 ans d'expérience avec la production de riz. Les résultats indiquent également que les agriculteurs perçoivent le dosage recommandé en tant que trop peu et augmentent donc le dosage. Ils souvent mélangent différents types de pesticides et n'utilisent pas tout leur équipement de protection tout en pulvérisant. Basé sur les résultats on lui recommande de développer des politiques de pesticide pour stimuler des agriculteurs pratiquer l'utilisation sûre de pesticide au Surinam.

Description : The globalization process, accelerating in the last 20 years, has raised important developmental stakes : on the one hand, economic questions with the multiplication of exchanges and its concentration in certain regions of the world; on the other hand globalization has also raised important social issues, with the acceleration of demographic flux and the whole question of "inclusion" associated with this; the issues are also environmental, through increased needs and resource limitations. Tourism represents the ideal vector of this globalization and the stakes it represents. By focusing on international tourism in a country in the South, this article seeks to better understand the stakes involved in developing international tourism resources, by seeking an answer to the question : In what ways can ecotourism constitute a real strategy for economic development, poverty alleviation, and contribute to economic growth and the protection of natural resources ? We will be examining this question in the context the Ranomafana National Park in Madagascar.

Résumé : International audience
Marine biological invasions threaten biodiversity worldwide. Here we explore how Marine Protected areas, by reducing human use of the coast, confer resilience against the introduction of non-indigenous species (NIS), using two very different Pacific islands as case studies for developing and testing mathematical models. We quantified NIS vectors and promoters on Vancouver (Canada) and Moorea (French Polynesia) islands, sampled and barcoded NIS, and tested models at different spatial scales with different types of interaction among vectors and between marine protection and NIS frequency. In our results NIS were negatively correlated with the dimension of the protected areas and the intensity of the protection. Small to medium geographical scale protection seemed to be efficient against NIS introductions. The likely benefit of MPAs was by exclusion of aquaculture, principally in Canada. These results emphasize the importance of marine protected areas for biodiversity conservation, and suggest that small or medium protected zones would confer efficient protection against NIS introduction.

Résumé : The overexploitation of fishery resources has led to a major fisheries crisis. In this context, artisanal fisheries, and in particular small-scale coastal fisheries, appear as relevant alternatives for a sustainable use of coastal resources. Marine Protected Areas (MPA) are more and more used as management tools for these fisheries, as protection effects and targeted access regulations may benefit to commercial fishers. Managers and scientists need then quantitative information not only to adapt their management to the fishing activity present on their territory, but also to estimate the effects of MPA management on it. This study provides catch and effort estimates that are essential for appraising and managing the artisanal fishery in the Côte Bleue Marine Park (CBMP), a French Mediterranean MPA including two No-Take Zones of different age and size. A field protocol was defined and implemented between July 2009 and June 2010 within the CBMP. Seven métiers were identified and characterized by target species, gear type, fishing grounds and fishing periods. During the one-year studied period, 3512 fishing trips and 4645 fishing operations were performed by 30 active boats in the Côte Bleue fishing territory, amounting to 9500 km of immersed nets. In total, approximately 130 tons of catch were landed in the six CBMP harbors, out of which 58% depend on the three main species caught on the Côte Bleue: hake (Merluccius merluccius), gilthead seabream (Sparus aurata) and common sole (Solea solea). The presented methodology could be part of a long term monitoring requiring close collaboration with local fishers. It enables adaptive management with respect to changes in fishing pressure (from inside and outside the MPA) that may impact the environment and its resources.

Description : Intervention portant sur l'étude de l'émergence de nouveaux territoires au Brésil appelées "réserves de conservation" ou "unités de conservation". Elles sont étroitement liées aux populations qui exploitent les ressources naturelles en commun sur ces territoires. Les réserves associent ainsi la conservation de l'environnement et les droits des populations traditionnelles. Elles sont le résultat d'importants mouvements sociaux des populations en réaction à l'industrie du bois et à l'agriculture intensive. Ces espaces reconnaissent par ailleurs la rationalité de ces populations par rapport à l'environnement et assure la sécurité de la terre, l'accès à l'eau et le respect des coutumes traditionnelles.

Résumé : International audience
Exposure to disturbance is rarely considered in marine protected area planning. Typically, representing and replicating the habitat types present within protected areas is used to spread the risk of protecting frequently disturbed sites. This was the approach used during the 2004 re-zoning of the Great Barrier Reef Marine Park (GBRMP) via the Representative Areas Program. Over 10 years later, we examine whether the risk was spread by mapping exposure of coral reefs in the GBRMP to four disturbances that cause coral mortality: bleaching, tropical cyclones, crown-of-thorns starfish outbreaks, and freshwater inundation. Our objectives were to: (1) assess whether no-take areas include a range of disturbance regimes, and (2) identify coral reef areas with lower relative exposure. At least 13% and an average of 31% of reef locations in each of 11 exposure classes are included within no-take areas. A greater proportion of low-exposure areas are within no-take areas than high-exposure areas (34.2% vs. 28.3%). The results demonstrate the value of risk spreading when exposure data are not available while also showing that regularly assessing exposure increases capacity for adaptive, resilience-based reef management.

Résumé : Integrating ecological connectivity into marine ecosystem management and planning is important, especially in a global context of severe fish stocks depletion and growing habitat degradation. Environmental tools such as Marine Protected Areas have been proposed to protect biodiversity, restore damaged ecosystems, sustain fisheries, and rebuild overexploited stocks. The effectiveness of marine protected areas depends in part on the maintenance of connectivity between marine populations, linked by ecological processes such as larval dispersal. In this thesis, we applied a biophysical model driven by ocean currents derived from satellite altimetry to evaluate connectivity between Western Indian Ocean reefs and across the current MPA system in the Mediterranean Sea. We applied different methods of analysis such as graph-theoretic and clustering. In the Western Indian Ocean, marine connectivity analyses show that the number of connections between reefs increases with fish pelagic larval duration. It also highlights a low connectivity across the region and a high interconnectivity within several regions (Mozambique Channel, Mascarene archipelago). In the Mediterranean Sea, connectance is globally low at the regional scale. This connectance is more important in Western than Eastern Mediterranean. Moreover, the marine connectivity analyses revealed high domestic connectivity rates. Depending on the study area, priority reefs or sites for MPA implementation are proposed. Finally, implications for transboundary marine policies and regional cooperation are discussed.
Intégrer les connaissances sur la connectivité écologique dans la gestion des écosystèmes marins est essentiel, surtout dans un contexte d'appauvrissement des ressources marines et de dégradation des habitats côtiers à l'échelle mondiale. Des outils environnementaux, tels que les Aires Marines Protégées ont été mises en œuvre pour protéger la biodiversité, restaurer les écosystèmes endommagés, soutenir les pêcheries et reconstituer les stocks surexploités. Leur efficacité dépend en partie du maintien de la connectivité entre les populations marines, assurée à travers divers processus écologiques dont la dispersion larvaire. Dans le cadre de ce travail de thèse, un modèle biophysique intégrant des données de courants, issues de mesures d'altimétrie par satellite, a été utilisé pour évaluer la connectivité entre les récifs de l'océan Indien d'une part, et à travers le réseau d'AMP de Méditerranée d'autre part. Différentes méthodes d'analyse ont été utilisées, telles que la théorie des graphes et le clustering. Dans l'océan Indien occidental, l'analyse des connectivités marines montre que le nombre de connexions entre les récifs augmente avec la durée de vie larvaire des poissons. Elle met également en évidence une faible connectivité à l'échelle de la région, mais une forte inter-connectivité au sein de plusieurs sous-régions (Canal du Mozambique, Mascareignes). En Méditerranée, la connectance est globalement faible à l'échelle régionale, bien que plus importante dans le bassin occidental que le bassin oriental. L'analyse des connectivités marines montre également un taux de connectivité élevé à l'échelle d'un même pays. Selon le cas d'étude, une liste de récifs ou de sites prioritaires dans la mise en œuvre des AMP a été proposée. Enfin, les implications de ces résultats en termes de politiques transfrontalières et de coopération régionale sont discutées.

Résumé : International audience
AimBiological invasions are major contributors to global change and native biodiversity decline. However, they are overlooked in marine conservation plans. Here, we examine for the first time the extent to which marine conservation planning research has addressed (or ignored) biological invasions. Furthermore, we explore the change of spatial priorities in conservation plans when different approaches are used to incorporate the presence and impacts of invasive species.LocationGlobal analysis with a focus on the Mediterranean Sea region.MethodsWe conducted a systematic literature review consisting of three steps: (1) article selection using a search engine, (2) abstract screening and (3) review of pertinent articles, which were identified in the second step. The information extracted included the scale and geographical location of each case study as well as the approach followed regarding invasive species. We also applied the software Marxan to produce and compare conservation plans for the Mediterranean Sea that either protect, or avoid areas impacted by invasives, or ignore the issue. One case study focused on the protection of critical habitats, and the other on endemic fish species.ResultsWe found that of 119 papers on marine spatial plans in specific biogeographic regions, only three (2.5%) explicitly took into account invasive species. When comparing the different conservation plans for each case study, we found that the majority of selected sites for protection (ca. 80%) changed in the critical habitat case study, while this proportion was lower but substantial (27%) in the endemic fish species case study.Main conclusionsBiological invasions are being widely disregarded when planning for conservation in the marine environment across local to global scales. More explicit consideration of biological invasions can significantly alter spatial conservation priorities. Future conservation plans should explicitly account for biological invasions to optimize the selection of marine protected areas.

Résumé : The eastern Baltic cod stock collapsed as a consequence of climate-driven adverse hydrographic conditions and over fishing and has remained at historically low levels. Spatio-temporal fishing closures [Marine Protected Areas (MPAs)] have been implemented since 1995, to protect and restore the spawning stock. However, no signs of recovery have been observed yet, either suggesting that MPAs are an inappropriate management measure or pointing towards suboptimal closure design. We used the spatially explicit fishery simulation model ISIS-Fish to evaluate proposed and implemented fishery closures, combining an age-structured population module with a multifleet exploitation module and a management module in a single model environment. The model is parameterized based on (i) the large amount of biological knowledge available for cod and (ii) an analysis of existing spatially disaggregated fishery data. As the population dynamics of eastern Baltic cod depend strongly on the climate-driven hydrographic regime, we considered two production regimes of the stock. MPAs were only effective for stock recovery when they reduced overall fishing effort. The performance of MPAs needs to be evaluated relative to environmental regimes, especially for stocks facing strong environmental variability.

Résumé : International audience
Marines Protected Areas (MPAs) are commonly used around the world as management tools to promote the sustainable use of marine resources. It is assumed that MPAs secure human livelihoods and well-being by protecting marine ecosystems and ecosystem services. However, the links between ecological effects of MPAs and services have rarely been explored. Here we review the different impacts of MPAs on ecosystem functioning and service provision. Results highlight that empirical evidence for positive effects of MPAs on ecosystem service provision by coastal marine ecosystems is accumulating. Finally, we identified knowledge gaps on which future research efforts could focus and empower marine resource managers to make more informed decisions and maximize the value derived from their natural resource base.

Résumé : International audience
With the health of the world’s oceans threatened as never before, it is becoming increasingly apparent that Marine Protected Areas (MPAs) play a vitally important role in protecting marine and coastal habitats. Management of Marine Protected Areas: A Network Perspective draws on the results of a major EU-sponsored research project related to the establishment of networks of MPAs in the Mediterranean and Black Seas that transpired from February 2011 to January 2016. Featuring contributions by leading university- and national research institute-based scientists, chapters utilize the latest research data and developments in marine conservation policy to explore issues related to ways in which networks of MPAs may amplify the effectiveness and conservation benefits of individual areas within them. Topics addressed include the broader socio-economic impacts of MPAs in the Mediterranean and Black Seas; the use of Marine Spatial Planning (MSP) to resolve conflicts between marine resource use and protection; special protection measures under the EU’s Marine Strategy Framework Directive (MSFD); ecological value assessments in the Black Sea; the Ecosystem Approach (EA) for managing marine ecosystems; MPAs along Turkey’s Black Sea coast; MPAs and offshore wind farms; and managing and monitoring MPA networks within and between the Black and Mediterranean Seas.Timely and important, Management of Marine Protected Areas: A Network Perspective offers invaluable insights into the role of MPAs in preserving the welfare and long-term viability of our world’s oceans.

Résumé : International audience
Different marine habitats are characterised by different soundscapes. How or which differences may be representative of the habitat characteristics and/or community structure remains however to be explored. A growing project in passive acoustics is to find a way to use soundscapes to have information on the habitat and on its changes. In this study we have successfully tested the potential of two acoustic indices, i.e. the average sound pressure level and the acoustic complexity index based on the frequency spectrum. Inside and outside marine protected areas of Moorea Island (French Polynesia), sound pressure level was positively correlated with the characteristics of the substratum and acoustic complexity was positively correlated with fish diversity. It clearly shows soundscape can be used to evaluate the acoustic features of marine protected areas, which presented a significantly higher ambient sound pressure level and were more acoustically complex than non-protected areas. This study further emphasizes the importance of acoustics as a tool in the monitoring of marine environments and in the elaboration and management of future conservation plans. Coral reef ecosystems are among the most biologically diverse and complex marine ecosystems worldwide. In addition to their biological and ecological importance, coral reefs support major economic and physical functions (e.g. food production, tourism, biotechnology development and coastal protection) that are essential for many countries 1. Unfortunately, coral reefs are severely threatened: 20% of coral reefs can no longer be defined as such, another 25% are currently endangered and another 25% will be endangered by 2050 2. The frequency and severity of natural perturbations (e.g. cyclone, outbreaks of predators, particularly the crown-of-thorns starfish [COTS] Acanthaster planci) and anthropogenic perturbations (e.g. ocean acidification, pesticides, rising seawater temperatures) on coral reefs have greatly increased worldwide in the last three decades, and, as a consequence, reef communities (fish, coral and benthic invertebrates) have suffered unprecedented levels of decline 3,4
