Résumé : Fire-free forest conversion with organic inputs as an alternative to slash-and-burn could improve agro-ecosystem sustainability. We assessed soil carbon mass changes in a sandy-clayey and well-drained soil in French Guiana after forest clearing by the chop-and-mulch method and crop establishment. At the experimental site of Combi, native forest was cut down in October 2008; woody biomass was chopped and incorporated into the top 20 cm of soil. After about one year of legume and grass cover, three forms of land management were compared: grassland (Urochloa ruziziensis), maize/soybean crop rotation with disk tillage and in direct seeding without tillage. There were four replicates. We measured 14.16 kg m(-2) of carbon in 2 mm-sieved soil down to 2 m depth for the initial forest. Forest clearing did not induce significant soil compaction; neither did any specific agricultural practice. In converted soils, C stocks were measured in the 0-30 cm layer after each crop for three years. Carbon mass changes for soil fractions <2 mm (soil C stock) and >2 mm (soil C pool) in the 0-5, 5-10, 10-20 and 20-30 cm soil layers were assessed on an equivalent soil mass basis. One year and 1.5 years after deforestation, higher C stocks (+0.64 to 1.16 kg C m(-2) yr(-1)) and C pools (+0.52 to 0.90 kg C m(-2) yr(-1)) were measured in converted soils, compared to those of the forest into the top 30 cm of soil. However, the masses of carbon in these converted soils declined later. The highest rates of carbon decrease were measured between 1.5 and 2 years after forest conversion in the <2 mm soil fraction, from 0.46 kg Cm-2 yr(-1) (in grassland soils) to 0.71 kg C m(-2) yr(-1) (in cropland under no tillage). The carbon pool declined during the third year at rates of 0.41 kg C m(-2) yr(-1) (cropland under disk tillage) to 0.76 kg C m(-2) yr(-1) (grassland soils). Three years after forest conversion, C masses in the top 30 cm of soils for grassland showed similar values than for forest. In comparison, the carbon stock in cropped soils managed under no tillage in direct seeding (without mulch) was significantly 17% and 16% lower than in forest and grassland soils, respectively. None of the studied agricultural practices succeeded in accumulating carbon from the chopped forest biomass.

Résumé : In a perfect-deficit approach (Yi, 2012), the daily maximum carbon storage capacity (CPC) of a given ecosystem for each year defines the perfect annual CPC curve. Deficits are the differences in the daily observational data for a given year against a perfect curve. The area between this curve and instantaneous canopy photosynthetic rates represents the potential productivity. Using an 11-year (2004 – 2014) eddy covariance flux and meteorological data, this perfect-deficit approach was used to examine the relationship between potential productivity and droughts occurring in 2005 and 2010 in a tropical rainforest of French Guiana, South America. Surprisingly, CPC deficits were only reduced by 24% (2005) and 19% (2010) from their respective perfect CPCs, indicating a subtle effect of drought to ecosystem productivity. Highest precipitation occurred in 2010 but precipitation deficits dropped drastically during this year (71% reduction from its perfect value) which reflects a drought condition. However, its deficits showed no correlation annually and seasonally. Soil water content (SWC) appeared to be the single driver for CPC deficits during long dry periods but is weakly correlated (r = 0.30; P <0.01 and r = 0.31; P <0.01, in 2005 and 2010, respectively). These results indicate that soil water is not a major limiting factor for productivity of this ecosystem during drought periods. In contrast, global radiation (Rg) corresponds to the peak of CPC deficits in 2010, but only 19% had been reduced from its ideal value. Yet, highest gross primary production (GPP) of 4106±231 gCm−2yr−1 occurred this year (mean 3753±231 gCm−2yr−1). Therefore, smaller deficits in Rg coupled with sufficient water may have induced higher productivity in 2010. Nevertheless, weaker correlations between potential productivity and climatic drivers may imply that other controlling aspects such as biological constraints may also have an effect to the dynamics of potential productivity during drought events, hence, must also be considered.

Résumé : Cette these porte sur une analyse de politique publique dans un champ d'action internationale, la cooperation au developpement. l'etude s'interesse particulierement au cas de la construction de la politique communautaire de cooperation au developpement, et de son affirmation visa- vis des politiques nationales europeennes. pour ce faire, cette these analyse d'un point de vue qualitatif les ressorts de l'action de l'union europeenne, a la fois pour penser le developpement dans la caraïbe, et pour penser et faire l'europe. de l'autonomisation d'une politique a l'harmonisation des politiques nationales par le bas, c'est une veritable recomposition du systeme d'acteurs qui s'opere. ce renforcement de l'integration europeenne, dans un domaine d'action partage, par le biais d'outils renouveles de l'action publique, dessine alors progressivement les premices et les contours du cadre legislatif qui a ete mis en place par le traite de lisbonne en 2009
This dissertation analyses a public policy in an international field of action: the development cooperation. the study focuses in particular on the emergence of the european community policy of development cooperation and its assertion towards european national policies. using a qualitative methodology, this research aims to improve the understanding of the motivation and the processes at stake within the european union. the field analysis has led to observe both how the development policy in the caribbean ras been thought and built, and how this process may rave an impact on the european integration process itself. from the empowerment of a policy to the harmonisation of national policies, this process carries also consequences on the system of actors, which ras been reconstructed by those changes. as a result, the european integration process has been strengthened in a field where the competence is generally shared between the eu and its member states. bringing out some new or renewed tools of public action, this outlines also some of the signs or provisions of the forthcoming legal and political framework, set up by the 2009 lisbon treaty

Résumé : A standardized rapid inventory method providing information on both tree species diversity and aboveground carbon stocks in tropical forests will be an important tool for evaluating efforts to conserve biodiversity and to estimate the carbon emissions that result from deforestation and degradation (REDD). Herein, we contrast five common plot methods differing in shape, size, and effort requirements to estimate tree diversity and aboveground tree biomass (AGB). We simulated the methods across six Neotropical forest sites that represent a broad gradient in forest structure, tree species richness, and floristic composition, and we assessed the relative performance of methods by evaluating the bias and precision of their estimates of AGB and tree diversity. For a given sample of forest area, a several small' (<1ha) sampling strategy led to a smaller coefficient of variation (CV) in the estimate of AGB than a few large' one. The effort (person-days) required to achieve an accurate AGB estimate (<10% CV), however, was greater for the smallest plots (0.1ha) than for a compromise approach using 0.5ha modified Gentry plots, which proved to be the most efficient method to estimate AGB across all forest types. Gentry plots were also the most efficient at providing accurate estimates of tree diversity (<10% CV of Hill number). We recommend the use of the 0.5ha modified Gentry plot method in future rapid inventories, and we discuss a set of criteria that should inform any choice of inventory method.

Résumé : L’outre-mer comprend des régions, des pays et des territoires aux statuts divers et au passé hérité en grande partie des grandes puissances européennes, ce qui les a placés dans une communauté d’intérêts avec les Etats auxquels ils sont rattachés mais aussi avec l’Union européenne (UE).Néanmoins, ces régions, pays et territoires n’ont eu cesse de reconstruire entre eux des liens historiques et culturels et de tisser des relations avec l’ensemble de l’outre-mer afin de présenter une cohérence d’ensemble dans leur négociation avec l’Union européenne.Les régions ultrapériphériques appliquent le droit communautaire tandis que les pays et territoires d’outre-mer, situés en dehors du territoire communautaire, connaissent un régime d’association avec l’Union européenne.Le Danemark, l’Espagne, la France, les Pays-Bas, le Portugal et le Royaume-Uni ont procédé aux réformes constitutionnelles autorisant de multiples évolutions statutaires dans le respect du droit à l’autodétermination des populations.Forts d’une évolution statutaire et d’un développement économique et social continu, les régions, pays et territoires d’outre-mer souhaitent maintenant faire valoir leurs droits et défendre leurs intérêts au niveau européen et sur la scène internationale.La globalisation des politiques les incite à se regrouper au sein d’institutions internationales. Le rattachement de ces territoires à des Etats de droit leur a ouvert la voie à des systèmes juridiques bien structurés mais aussi aux valeurs européennes. Leur ultrapériphérité les a placés dans une situation géopolitique qui les a fait accéder aux relations internationales.L’objet de cette thèse est de démontrer l’interdépendance entre ces différents ordres juridiques et l’influence du droit européen et du droit international sur l’évolution statutaire de l’outre-mer vers davantage d’autonomie, mais aussi de responsabilisation et de prise en charge de son développement au moyen d’une implication dans son environnement régional, d’une coopération inter-régionale ou transnationale et d’une participation aux travaux des organisations internationales.
The Overseas regions, countries and territories present various statuses inherited mainly from the major European Powers which placed them in a relationship of a common interest not only with their mother countries but also with the European Union (EU).However, these territories have continuously re-built between them historical and cultural links, and weaved relationship within the entire Overseas to appear as a constituted whole while negotiating with the EU.The outermost regions (OR) apply Community Law while the Overseas Countries and territories (OCT) situated outside the territory of the Community, have Association Arrangements with the EU.Denmark, France, Netherlands, Portugal, Spain and United Kingdom have proceeded to necessary constitutional reforms to allow numerous articles amendments in respect of right to self-determination of peoples.At the light of statutory amendments and of a continuous economic and social development, the Outermost regions (OR) and the Overseas Countries and Territories (OCT), now wish to assert their rights and to defend their interests at European and International level.Globalisation of policies encourages OR and OCT to gather within International bodies. The rule of law of the related countries opens them to well-structured legal systems and to European values. The outermost geopolitical localisation makes them to have access to international relations.The purpose of this thesis is to demonstrate the interdependence between these different legal systems and the impact of European and International Law on the statutory amendments of the Overseas towards more autonomy, but also liabilities and involvement on their own development by using their regional environment, inter-regional and transnational cooperation and taking part at the works of international organisations.

Résumé : International audience
Ethnopharmacological relevancePsidium acutangulum Mart. ex DC is a small tree used by the Wayana Amerindians from the Upper-Maroni in French Guiana for the treatment of malaria.Aim of the studyIn a previous study, we highlighted the in vitro antiplasmodial, antioxidant and anti-inflammatory potential of the traditional decoction of P. acutangulum aerial parts. Our goal was then to investigate on the origin of the biological activity of the traditional remedy, and eventually characterize active constituents.Materials and methodsLiquid-liquid extractions were performed on the decoction, and the antiplasmodial activity evaluated against chloroquine-resistant FcB1 ([3H]-hypoxanthine bioassay) and 7G8 (pLDH bioassay) P. falciparum strains, and on a chloroquine sensitive NF54 ([3H]-hypoxanthine bioassay) P. falciparum strain. The ethyl acetate fraction (D) was active and underwent bioguided fractionation. All the isolated compounds were tested on P. falciparum FcB1 strain. In vitro anti-inflammatory activity (IL-1β, IL-6, IL-8, TNFα) of the ethyl acetate fraction and of an anti-Plasmodium active compound, was concurrently assessed on LPS-stimulated human PBMC and NO secretion inhibition was measured on LPS stimulated RAW murine macrophages. Cytotoxicity of the fractions and pure compounds was measured on VERO cells, L6 mammalian cells, PBMCs, and RAW cells.ResultsFractionation of the ethyl acetate soluble fraction (IC50 ranging from 3.4 to <1 µg/mL depending on the parasite strain) led to the isolation of six pure compounds: catechin and five glycosylated quercetin derivatives. These compounds have never been isolated from this plant species. Two of these compounds (wayanin and guaijaverin) were found to be moderately active against P. falciparum FcB1 in vitro (IC50 5.5 and 6.9 µM respectively). We proposed the name wayanin during public meetings organized in June 2015 in the Upper-Maroni villages, in homage to the medicinal knowledge of the Wayana population. At 50 µg/mL, the ethyl acetate fraction (D) significantly inhibited IL-1β secretion (−46%) and NO production (−21%), as previously observed for the decoction. The effects of D and guiajaverin (4) on the secretion of other cytokines or NO production were not significant.ConclusionsThe confirmed antiplasmodial activity of the ethyl acetate soluble fraction of the decoction and of the isolated compounds support the previous results obtained on the P. acutangulum decoction. The antiplasmodial activity might be due to a mixture of moderately active non-toxic flavonoids. The anti-inflammatory activities were less marked for ethyl acetate fraction (D) than for the decoction.

Résumé : International audience
Over the past decade, much attention has been devoted to the development of forest biomass estimation methods at a stand scale, leading to the establishment of allometric models (Chave et al., 2014). These allometric equations use a unique wood specific gravity value (WSG) per species, but neglect the within tree variations of WSG found by others (Wiemann & Williamson, 1989).The main objectives of this study are (1) to illustrate the diversity of radial (from pith to bark) and longitudinal (from bottom to top) patterns of WSG variation within and between species, (2) to highlight different trends of WSG radial variations and the possible misinterpretations of these trends due to the effect of heartwood and (3) to link these variations and patterns to the successional status of the species (from pioneer to sciaphilic species).We sampled 33 small trees (10 Wood sciences underpinning tropical ecology and management.

Résumé : International audience
The seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements and 35 litter productivity measurements), their associated canopy photosynthetic capacity (enhanced vegetation index, EVI) and climate, we ask how carbon assimilation and aboveground allocation are related to climate seasonality in tropical forests and how they interact in the seasonal carbon cycle. We found that canopy photosynthetic capacity seasonality responds positively to precipitation when rainfall is < 2000 mm yr(-1) (water-limited forests) and to radiation otherwise (light-limited forests). On the other hand, independent of climate limitations, wood productivity and litterfall are driven by seasonal variation in precipitation and evapotranspiration, respectively. Consequently, light-limited forests present an asynchronism between canopy photosynthetic capacity and wood productivity. First-order control by precipitation likely indicates a decrease in tropical forest productivity in a drier climate in water-limited forest, and in current light-limited forest with future rainfall < 2000 mm yr(-1).

Résumé : In the framework of French-Brazil co-operation, the French Institute of research for exploitation of the sea (IFREMER), the State of Bahia and the company Littoral Sul Maricultura have developed a new technique for shrimp farming (Penaeus vannamei) using floating cages. After trials carried out during three years, this technique turns out very interesting from several viewpoints. The growth speed and the survival rate are very good, the negative effects on the environmental quality are weak and local fishermen have proved eager to adopt this technique as a part-time activity. In the same time, a technico-economic analysis, using a computerised simulation tool, as well as a market analysis in the State of Bahia have been carried out in order to assess the feasibility of such a project and to help research and development decisions. Despite low first investment and good biological results, the ex-farm production cost of shrimps weighing 15 g is as high as 4,5 US$ per kilo. This price is due to the low productivity of the labour and to the cost of nets which have a short life-time. It is possible to consider this activity as profitable on the market of Salvador de Bahia. Nevertheless, the question is how to face the international competition, which is particularly strong in the case of tropical shrimps. The conditions allowing enterprises to develop a strategy based on product quality and environmentally friendliness are reviewed. [NOT CONTROLLED OCR]
Dans le cadre de la coopération Franco-Brésilienne, l'IFREMER, l'Etat de Bahia et la société Littoral Sul Maricultura ont développé une nouvelle technique d'élevage de crevettes pénéides (Penaeus vannamei) en utilisant des cages flottantes. Après trois années de mise au point, cette technique s'est avérée intéressante sur plusieurs aspects. La vitesse de croissance et le taux de survie sont très satisfaisants, les effets négatifs sur la qualité du milieu naturel sont faibles et les pêcheurs locaux ont accueilli favorablement cette nouvelle pratique en complément de leur activité traditionnelle. Parallèlement, une analyse technico-économique utilisant un outil de simulation informatique ainsi qu'une analyse du marché de la crevette dans l'état de Bahia ont été conduites afin d'évaluer la faisabilité d'un tel projet et d'orienter les actions de recherche et développement. En dépit d'investissements initiaux plus faibles que dans les élevages en bassins et de bonnes performances zootechniques, le coût de production de crevettes de 15 g atteint 4,7 US$ par kilo. Dans les conditions de marché de l'Etat de Bahia, la rentabilité d'un projet d'élevage de crevettes en cage serait assurée, mais la faible productivité du travail et le coût de remplacement des filets ne permettent pas d'avoir des coûts de production aussi bas que dans les élevages en bassins. C'est pourquoi la question se pose de la possibilité pour ce type de production innovante d'affronter une concurrence internationale très forte comme dans le cas des crevettes tropicales. En particulier, les conditions dans lesquelles les entreprises peuvent développer une stratégie de compétitivité basée sur la qualité de leurs produits et sur le respect de l'environnement sont analysées.

Description : La façon dont la République dominicaine traite les migrants haïtiens et les citoyens dominicains d?origine haïtienne a dominé la problématique des droits humains en 2015. Les autorités gouvernementales continuent à faire suite à une décision prise par la Cour constitutionnelle en 2013, et qui avait privé de leur nationalité des dizaines de milliers de Dominicains issus de familles migrantes, pour la plupart originaires d?Haïti, en menant une double politique consistant à réenregistrer les citoyens déchu de leur nationalité tout en pratiquant des expulsions massives. Dans le même temps, le gouvernement a pour la première fois engagé un effort global pour régulariser le statut des migrants sans papiers, pour la plupart Haïtiens. En novembre 2014, la Cour constitutionnelle a également mis en danger l?ensemble des protections des droits humains en déclarant inconstitutionnelle l?adhésion du gouvernement en 1999 à la juridiction de la Cour interaméricaine des droits de l?homme. Cette décision a créé un vide juridique qui n?a toujours pas été résolu.

Résumé : The consciousness of a necessary international co-operation about the fight against marine pollution is relatively recent. In a first time, the concerned states have contracted, at the universal and regional level, some agreements in a punctual way, to organize this fight. From the 1970th, the United States are going to systematize and rationalize this conventional movement aimed to preserve the marine environnement by the working of a standardizing planning liable to be used in some threatened zones, it is the Activities Programm for the regional seas proceeding from the United States Programm for the Environment. For each regional sea reserved by the Programm ; corresponds a whole appliance contained in an Action Plan. Amid each Action Plan, a juridical appliance is foreseen which enables the riverside states to juridically, institutionally and financially organize their co-operation in touch with the International Organizations of the United States system.

Résumé : Ants have evolved venoms rich in peptides and proteins used for predation, defense, and communication. However, they remain extremely understudied due to the minimal amount of venom secreted by each ant. The present study investigated the differences in the proteome and peptidome of the venom from the bullet ant, Paraponera clavata. Venom samples were collected from a single colony either by manual venom gland dissection or by electrical stimulation and were compared using proteomic methods. Venom proteins were separated by 2D-PAGE and identified by nanoLC-ESI-QTOF MS/MS. Venom peptides were initially separated using C18 reversed-phase high-performance liquid chromatography, then analyzed by MALDI-TOF MS. The proteomic analysis revealed numerous proteins that could be assigned a biological function (total 94), mainly as toxins, or roles in cell regulation and transport. This investigation found that ca. 73% of the proteins were common to venoms collected by the two methods. The peptidomic analysis revealed a large number of peptides (total 309) but with <20% shared by the two collection methods. There was also a marked difference between venoms obtained by venom gland dissection from different ant colonies. These findings demonstrate the rich composition and variability of P. clavata venom.

Résumé : Le tourisme de masse ayant déjà démontré ses limites et fait l’objet de critiques et d’indignation de la part des associations internationales de la protection de l’environnement cède peu à peu sa place au tourisme durable. Ce dernier tient compte de la protection de l’environnement et de la sauvegarde des richesses naturelles en offrant aux touristes des produits purement bio et des cultures tout à fait originales.Dans un contexte connu par sa complexité, vu les inégalités environnementales et sociales que connaît le Maroc, et pour remédier ce déséquilibre des acteurs économiques, des locaux dans la majorité des cas, ont opté pour des investissements touristiques dans les milieux ruraux. Ainsi des établissements touristiques ruraux commencent à prendre de l’ampleur, visant à consolider la notion du tourisme durable avec ses produits artisanaux locaux, ses variétés culinaires régionales et ses folklores saisonniers aux traditions bien enracinées. Mais ces actions sont-elles en mesure d’assurer un avenir prometteur à ces établissements ruraux, sans l’intervention de l’État qui a un rôle primordial à jouer en la matière de la formation et la qualification des ressources humaines dans le secteur du tourisme ; une formation pour préserver l’environnement et les ressources naturelles et donner un nouvel élan au tourisme rural dont la modernité demeure une référence essentielle.Par la beauté naturelle de leurs sites, la qualité de leurs aliments, le comportement clair et limpide de leurs personnes, les établissements d’hébergements touristiques ruraux marocains attirent déjà un nombre significatif de touristes qui viennent à l’origine pour un séjour de deux ou trois jours et prolongent souvent à une semaine séduits par la qualité du séjour. Eau pure, qualité de l’air, richesse culturelle, autant d’atouts qui justifient le soutien de ce genre de tourisme qui inspire notre enquête au niveau de la commune rurale d’Asni.
It is high people admitted that mass tourism has its limits as there have been consequences. Indeed several NGOS as well as international organizations aiming at the protection of the environment see that this destructive or harmful tourism is losing ground it is being substituted or replaced by eco-friendly tourism. This latter target the preservation of mother earth as well as its natural resources by providing a new type of tourism labeled rural tourism whose first and paramount objective is providing tourists with organic products. This green or rural tourism tries at all cost to promote artistic commodities, authentic cultures and purely traditional folk.Rural tourism is actually expecting more prosperity and progress but on condition that the local authorities and the government cooperate more to give a push to this kind of business via a perfect or division of human resources. Rural tourism represent a new image of modern tourism that aims to protect the environment and diversity. From the beauty of the natural land scape, the quality of the food served, the professionalism of the staff members the touristic accommodation units based in Moroccan countryside manage to attract a significant number of tourists, who often come for 2 or 3 days prolong their stay for a week for having fond a deep pleasure. The water is pure, the atmospheric air is filtered, the cultural wealth is vast, it is therefore appropriate to sustain and support this kind of tourism that inspires our investigation at the rural town of Asni.
