Résumé : International audience
Despite improvements in air quality in developed countries, air pollution remains a major public health issue. To fully assess the health impact, we must consider that air pollution exposure has both physical and psychological effects; this latter dimension, less documented, is more difficult to measure and subjective indicators constitute an appropriate alternative. In this context, this work presents the methodological development of a new scale to measure the perception of air quality, useful as an exposure or risk appraisal metric in public health contexts. On the basis of the responses from 2,522 subjects in eight French cities, psychometric methods are used to construct the scale from 22 items that assess risk perception (anxiety about health and quality of life) and the extent to which air pollution is a nuisance (sensorial perception and symptoms). The scale is robust, reproducible, and discriminates between subpopulations more susceptible to poor air pollution perception. The individual risk factors of poor air pollution perception are coherent with those findings in the risk perception literature. Perception of air pollution by the general public is a key issue in the development of comprehensive risk assessment studies as well as in air pollution risk management and policy. This study offers a useful new tool to measure such efforts and to help set priorities for air quality improvements in combination with air quality measurements.

Résumé : International audience
Mapping spatial distributions of disease occurrence can serve as a useful tool for identifying exposures of public health concern. Infant mortality is an important indicator of the health status of a population. Recent literature suggests that neighborhood deprivation status can modify the effect of air pollution on preterm delivery, a known risk factor for infant mortality. We investigated the effect of neighborhood social deprivation on the association between exposure to ambient air NO2 and infant mortality in the Lille and Lyon metropolitan areas, north and center of France, respectively, between 2002 and 2009. We conducted an ecological study using a neighborhood deprivation index estimated at the French census block from the 2006 census data. Infant mortality data were collected from local councils and geocoded using the address of residence. We generated maps using generalized additive models, smoothing on longitude and latitude while adjusting for covariates. We used permutation tests to examine the overall importance of location in the model and identify areas of increased and decreased risk. The average death rate was 4.2‰ and 4.6‰ live births for the Lille and Lyon metropolitan areas during the period. We found evidence of statistically significant precise clusters of elevated infant mortality for Lille and an east-west gradient of infant mortality risk for Lyon. Exposure to NO2 did not explain the spatial relationship. The Lille MA, socioeconomic deprivation index explained the spatial variation observed. These techniques provide evidence of clusters of significantly elevated infant mortality risk in relation with the neighborhood socioeconomic status. This method could be used for public policy management to determine priority areas for interventions. Moreover, taking into account the relationship between social and environmental exposure may help identify areas with cumulative inequalities.

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

Résumé : Le bassin du fleuve Sixaola est un bassin transfrontalier partagé entre le Costa Rica et le Panama. Localisé sur la façade caraïbe de l’isthme centraméricain, il est depuis une vingtaine d’années considérées par les organismes de coopération et les organisations non gouvernementales comme un espace privilégié pour la coopération en matière environnementale. Ce bassin concentre en effet d’importantes richesses naturelles et culturelles propres à cette façade caraïbe. Dans le même temps, on y constate une importante vulnérabilité sociale et des dégradations environnementales croissantes, d’autant plus qu’on trouve autour de ce bassin des activités productives polluantes (monocultures, tourisme, etc.), ainsi que les villages les plus pauvres des deux pays.Cet article cherche à analyser comment, à côté des mécanismes d’intégration et des initiatives appuyées par les États, cet espace connaît aussi de nombreux projets et programmes de coopération menés par des organismes internationaux et des organisations non gouvernementales (ONG). Ces projets visent principalement à accroître la coopération transfrontalière pour la conservation et la gestion environnementale.En revanche, leur rôle est de plus en plus remis en cause par des acteurs locaux qui affirment que ces organismes « transnationaux » déplacent les États et imposent des projets qui ne prennent pas en compte les réalités et les besoins locaux tout en développant des discours « hégémoniques » sur la gestion intégrée des bassins transfrontaliers, le changement climatique, entre autres.
The Sixaola River basin is shared by Costa Rica and Panama. On the Caribbean side of the Central American Isthmus, it has been considered by cooperation organisms and non-governmental organizations as a privileged space for environmental cooperation for the past 20 years. This basin in fact concentrates an important amount of natural and cultural heritage that is endemic to this side of the Caribbean. At the same time, one can observe increasing social vulnerability and environmental degradation related to the presence of the poorest communities of both Panama and Costa Rica within the basin, and to polluting activities (monoculture, tourism, etc.) carried out around it.This article analyzes how this space is the locus of State integration mechanisms and other initiatives, at the same time that it harbors international organism and non-governmental cooperation programs. These latter projects claim to increase trans-border cooperation for conservation and environmental management.But their role is increasingly being contested by local stakeholders, who more and more claim that these “transnational” organisms displace States and impose projects that do not take into account local realities and needs, while developing “hegemonic” discourses on integrated management of trans-border basins and climate change, among other issues.

Résumé : Chlordecone is a very persistent insecticide used in banana plantations of the French West Indies between 1972 and 1993. Chlordecone residues were found in inland water, in agricultural and freshwater products, and in marine organisms. This pollution has become of great concern in 2007. Therefore, a governmental action Plan was launched to better assess the pollution and to improve the consumer’s protection. Within this plan, 1048 samples from 69 different species of marine fishes and crustaceans were collected all around both the Guadeloupe and the Martinique Islands and analyzed. The results confirm the presence of chlordecone in marine organisms, with highly variable concentrations (from the detection limit to 1000 μg.kg-1). In 17.9 % of the samples, concentrations exceeded 20 μg.kg-1, the maximum acceptable level in fish according to the French regulation (Anon, 2008). Two main features of this contamination were characterized. 1) Because of the sedimentation of contaminated suspended soil particles, the sheltered bays are more exposed to chlordecone than the open coast where terrigenous flux are dispersed. 2) Species biology, particularly their lifestyle and diet, appear to influence contamination levels. Thus, the more contaminated species live in relation with sediment or are at high trophic level. These results have directly supported political decisions in order to prevent too high exposure of consumers to chlordecone. Fishing activities in sheltered bays have been forbidden for potentially highly contaminated species like benthic crustaceans and top predators. Further studies are under way to assess the importance of the trophic transport of chlordecone within the foodweb, and to evaluate the historical deposition of this insecticide in sediment and its further bioavailability.

Résumé : International audience
This study aims to assess the evidence on adverse pregnancy outcome associated with living close to polluted industrial sites, and identify the strengths and weaknesses of published epidemiological studies. A systematic literature search has been performed on all epidemiological studies published in developed countries since 1990, on the association between residential proximity to industrial sites (hazardous waste sites, industrial facilities and landfill sites) and adverse pregnancy outcome (low birth weight, preterm birth, small for gestational age, intrauterine growth retardation, infant mortality, congenital malformation). Based on 41 papers, our review reveals an excess risk of reproductive morbidity. However, no studies show significant excess risk of mortality including fetal death, neonatal or infant mortality and stillbirth. All published studies tend to show an increased risk of congenital abnormalities, yet not all are statistically significant. All but two of these studies revealed an excess risk of low birth weight. Results for preterm birth, small for gestational age and intrauterine growth retardation show the same pattern. There is suggestive evidence from the post-1990 literature that residential proximity to polluted sites (including landfills, hazardous waste sites and industrial facilities) might contribute to adverse reproductive outcomes, especially congenital malformations and low birth weight—though not mortality. This body of evidence has limitations that impede the formulation of firm conclusions, and new, well-focused studies are called for. The review findings suggest that continued strengthening of rules governing industrial emissions as well as industrial waste management and improved land use planning are needed.

Résumé : International audience
The Société de pneumologie de langue française defines acute exacerbation of chronic obstructive pulmonary disease (AE COPD) as an increase in daily respiratory symptoms, basically duration ≥ 48h or need for treatment adjustment. Etiology of EA COPD are mainly infectious, viral (rhinovirus, influenzae or parainfluenzae virus, coronavirus, adenovirus and respiratory syncytial virus) or bacterial (Haemophilus influenzae, Streptococcus pneumoniae, or Moraxella catarrhalis). Pollutant exposure can also lead to AE COPD, such as NO2, SO2, ozone or particulates (PM10 and PM2.5). In 30% the etiology remains unknown. Differential diagnoses of AE COPD include infectious pneumonia, pneumothorax, acute heart failure and pulmonary embolism. Presences of signs of severity impose hospitalization: signs of respiratory distress, shock, acute confusion but also fragile patients, insufficient home support or absence of response to initial treatment. AE COPD treatments consist on increase in bronchodilators, chest physiotherapy, and antibiotics if sputum is frankly purulent. Systemic corticosteroids should not be systematic.Recommended dose is 0.5 mg/kg on short course (7 days). During hospitalization, oxygen supplementation and thromboprophylaxis could be prescribed. The main interest in noninvasive ventilation is persistent hypercapnia despite optimal medical management. During ambulatory management or hospitalization, clinical assessment at 48-72h is mandatory. L’exacerbation aiguë de bronchopneumopathie chronique obstructive (EA BPCO) représente un événement important dans l’histoire naturelle de la BPCO, notamment en cas d’hospitalisation. Les EA BPCO interviennent dans la gravité et l’évolution de la BPCO ; et leur prévention est un des objectifs principal des traitements de fond.
La Société de pneumologie de langue française définie l’exacerbation aiguë de bronchopneumopathie chronique obstructive (EA BPCO) comme une majoration des symptômes respiratoires au-delà des variations quotidiennes, en pratique, d’une durée ≥ 48h ou justifiant une modification thérapeutique. L’étiologie de ces EA BPCO est principalement infectieuse, virale (rhinovirus, virus influenzae et parainfluenzae, coronavirus, adénovirus et virus respiratoire syncytial) ou bactérienne (principalement Haemophilus influenzae, Streptococcus pneumoniae et Moraxella catarrhalis). Elles peuvent également résulter de l’exposition à certains polluants comme le NO2, le SO2, l’ozone et la pollution particulaire (PM10 et PM2,5). L’étiologie reste indéterminée dans près de 30 % des cas. Les diagnostics différentiels des EA BPCO incluent les pneumopathies infectieuses, les pneumothorax, les poussées d’insuffisance cardiaque et les embolies pulmonaires. La présence de signes de gravité conditionnent l’hospitalisation : signes d’insuffisance respiratoire aiguë, de choc ou de défaillance neurologique, mais aussi en cas de patient fragile, d’absence de soutien familial à domicile ou d’absence de réponse au traitement initial. Le traitement d’une EA BPCO consiste en une majoration des bronchodilatateurs, une kinésithérapie respiratoire, une antibiothérapie en cas d’expectoration franchement purulente.La prescription de corticoïdes systémiques ne doit pas être systématique. La dose recommandée est de 0,5 mg/kg sur une courte période (7 jours). Lors d’une hospitalisation, une oxygénothérapie et une thromboprophylaxie peuvent être prescrite. La ventilation noninvasiveest principalement indiquée en cas de persistance d’une hypercapnie malgré un traitement médical optimal. Que le patient soit pris en charge en ambulatoire ou en hospitalisation, une réévaluation clinique à 48-72h est indispensable.

Résumé : International audience
Ecological resilience assessments are an important part of resilience-based management (RBM) and can help prioritize and target management actions. Use of such assessments has been limited due to a lack of clear guidance on the assessment process. This study builds on the latest scientific advances in RBM to provide that guidance from a resilience assessment undertaken in the Commonwealth of the Northern Mariana Islands (CNMI). We assessed spatial variation in ecological resilience potential at 78 forereef sites near the populated islands of the CNMI: Saipan, Tinian/Aguijan, and Rota. The assessments are based on measuring indicators of resilience processes and are combined with information on anthropogenic stress and larval connectivity. We find great spatial variation in relative resilience potential with many high resilience sites near Saipan (5 of 7) and low resilience sites near Rota (7 of 9). Criteria were developed to identify priority sites for six types of management actions (e.g., conservation, land-based sources of pollution reduction, and fishery management and enforcement) and 51 of the 78 sites met at least one of the sets of criteria. The connectivity simulations developed indicate that Tinian and Aguijan are each roughly 10 × the larvae source that Rota is and twice as frequent a destination. These results may explain the lower relative resilience potential of Rota reefs and indicates that actions in Saipan and Tinian/Aguijan will be important to maintaining supply of larvae. The process we describe for undertaking resilience assessments can be tailored for use in coral reef areas globally and applied to other ecosystems.

Résumé : International audience
1. The use of targets to provide measurable objectives and benchmarks for management, conservation, andrestoration of ecosystems is commonplace. In the marine and coastal realms, targets have been successful insetting sustainable limits to fisheries harvests, thresholds for pollutants, and recommended amounts ofrepresentative habitat included in marine protected area (MPA) networks. Quantifiable targets can dissuadegovernments from making dubious claims about investments in ocean protection that sound impressive butcannot be verified. Examples are presented where protection targets have been used successfully for marinemanagement, and instances where measurable and meaningful benchmarks serve to allow tracking of true progress.2. However, the setting of targets can also be a double-edged sword. In some cases, targets have proven useful,but in many instances, interventions made to fulfil targets not only give a false illusion of progress or even success,they present opportunity costs that impede further conservation.3. Some of these issues were raised in the 2003 article ‘Dangerous Targets?: Unresolved issues and ideologicalclashes around marine protected areas’ that appeared in Aquatic Conservation: Marine and FreshwaterEcosystems. Since its publication, the article’s warnings about how targets can sometimes be dangerous andcounter-productive have led to intense debate among scientists and policy-makers alike, and the paper has beencited in more than 500 publications. Yet today, more than a dozen years after the first ‘Dangerous Targets’publication, new targets are driving more MPA designations and conservation strategies than ever before, andthe ‘dangerous’ aspects of target setting have been largely ignored.4. This paper discusses old ‘dangers’ in the context of new developments in marine conservation, including thelingering problem of having simplistic metrics drive marine policies, and the unintended result that can often occurwhen outputs (percentage of area under MPA designation) do not align with true outcomes of effectivemanagement and conservation. Newly emerging ‘dangers’ in letting areal targets (percentage of area underMPA designation) drive MPA designations are also discussed, including how the rush to fulfil obligations toprotect a certain proportion of area is taking place in planning, separate from broader level, and potentiallymore holistic, marine spatial planning (MSP).5. The paper suggests five recommendations that would allow policy-makers to use targets more effectively,including: (1) increase transparency in planning, especially around specific goals and objectives of MPAestablishment; (2) use time-based areal targets when representativity is a goal of the protected area strategy; (3)

Résumé : International audience
The INTERREG Caribbean IV program recommends the valorization and protection of the region's environmental core, through collaborative and sustainable management of resources. It uses Martinique as the test case. The French territories of Saint-Martin, Saint-Barthélemy, Guadeloupe, and Martinique, and the member states of the Organization of Eastern Caribbean States are part of a geographic continuum that can easily be identified through its similar landscapes, climates, and natural resources and also through the environmental degradation the states have to face, caused by human activity (pollution and deterioration of ecosystems and habitats), natural hazards, and climate change including sea level rise. Therefore the islands of the Lesser Antilles are faced with an important developmental and environmental challenge, which could be easily summarized as a struggle for balance.

Résumé : La gestion du foncier martiniquais est un sujet complexe, sensible et à forte densité politique. La superficie de la Martinique est de 1 100km2, soit l’une des plus petites régions françaises, avec la plus forte densité de population, soumise à de multirisques (cyclonique, sismique, volcanique, technologique, inondation, pollution de l’air, des sols et de l’eau, tsunami…).La triangulation urbanistique composée d’une multiplicité d’acteurs, de textes et de réglementations et d’un millefeuille institutionnel (6 niveaux d’administration : commune, intercommunalité, département, région, Etat, Europe) annihile toute responsabilité et obère un développement endogène de ce micro territoire.Un juste équilibre entre développement économique, social, culturel et environnemental doit être trouvé en conciliant les objectifs économiques et sociaux liés au développement insulaire.La remarquable biodiversité de la Martinique constitue un atout touristique indéniable, menacé par de fortes pressions anthropiques foncières.Cette recherche démontre la pertinence de la réglementation applicable au foncier à la Martinique et l’influence du développement durable sur cette réglementation. La thèse propose des solutions pérennes à mettre en œuvre pour pallier les incohérences juridiques révélées par l’étude.
Management of land in Martinique is a complex, sensitive and highly political topic.The total area of the island is 1 100 km2 (square meters), e.g, one of the smallest French areas, with the highest concentration of population, submitted to multirisk desasters (cyclonic, seismic, volcanic, technological, flood, air, ground and water pollutions, tsunami…).The urban triangulation made up of a multiplicity of actors, texts and regulations, as well as a multi-level institutional cream cake (6 levels of administration: the city, the intercity, the Department, the Regional Council, the State and Europe), destroys all kind of responsibility and obstruct an endogenous development of this micro territory.A fair balance between economic, social, cultural and environmental development is necessary, by reconciling with the economic and social goals related to the insular development.The astonishing biodiversity of the island of Martinique represents an obvious tourist asset, threatened by strong land anthropic pressures.This research study highlights the relevance of the regulation applicable to the land in Martinique as well as the influence of sustainable development on this regulation. This thesis suggests perennial solutions to implement, in order to mitigate the legal inconsistencies pointed out by the study.

Résumé : International audience
Decreasing growth rate (Feeley et al., 2007) and large die-back due to drought (Phillips et al., 2009) suggest that tropical forests are suffering recent climate changes. Forest vulnerability to external factors (e.g. air pollution, acid rain) is widely studied in northern countries, while only a few attempts have investigated crown integrity in the Tropics. The method needs to be generic enough to account for the large number of species and crown shapes encountered in tropical forests. In the present study, we developed and tested a novel field method that estimates crown fragmentation (main branch mortality (MB) and secondary branch mortality (SB)), liana infestation (LI) and crown position (CP) in the canopy. The relationship between crown fragmentation and annual growth rate (agr) was investigated through multiple regression. Six out of eight canopy tree species showed significant growth decline with increasing crown fragmentation. Higher probability of death was also found in trees with severe crown fragmentation. The capacity of such crown assessment to depict tree vitality in a forest stand is discussed along with potential applications in both forest science and management

Résumé : Industrial agriculture has clearly reached its limits. Industrial agriculture is not able anymore to satisfy the basic needs of the growing worldwide population while ensuring the conditions of reproduction of natural assets. New production models have to be designed to protect and reclame polluted and degraded agricultural areas. Agroecology is considered as a promising way to achieve ecologically-intensive agrosystems, since the seminal contribution of Altieri in 1995. Nevertheless agroecology has not fully emerged as a scientific discipline yet. Agroecology is more that a traditional scientific discipline because agroecology breaks the frontiers between biophysical sciences and social sciences. This chapter reviews the roots and evolution of agroecology in the first section. Here we propose a mathematical theory of viability to handle uncertainty and complexity within agrosystems. This theory allows to define a kern of viability in which the agrosystem stay viable in the long term (section “Scientific stakes: New frontiers”). However, agroecological innovations create new uncertainties and controversies that must be solved. Some solutions can be found individually while other solutions must by co-constructed using innovative collective actions and hydrid forums (Callon et al. 2001, section “Scientific controversy and uncertainty”). Such collective knowledge makes agroecology as the starting point of a representative democracy by setting up adaptive governance on territories (section “How to manage agrosystems in the context of global changes?”).

Résumé : International audience
The development of transport infrastructures lead to increase the exposure of population to high noise levels. The objective of this work is to define an indicator representative of the health risk induced by noise pollution in urban environment and adapted to the geographical resolution of IRIS. The methodology for the definition of the indicator considers in a first part the health aspect with the health data for the following effects: annoyance, sleep disturbance and cardiovascular diseases. Then, in a second part, methodology considers some effects related to the urban context since the configuration of urban space can change the exposure of population to noise and the perception of noise. The work is achieved with a GIS software and the input acoustical data comes from noise maps calculated for the END. The indicator seems to be relevant and interesting as it brings health information.

Résumé : International audience
Environmental context The safeguarding of water supplies and drinking water is a major issue when considering human health risk management. In this context, an automatic and on-site fractionation system for the detection of organic contaminants has been developed. The main goal of this system is to establish an initial diagnosis by identifying a class of substances involved in a case of pollution. Abstract This paper proposes a new approach for the preconcentration, fractionation, prediction and detection of organic micropollutants in water. The main aim of this study was to implement an innovative fractionation method and a prediction model based on the physicochemical properties of compounds and interactions with the sorbent of solid-phase extraction cartridges. Two sorbents (Strata-SAX and Oasis-HLB) and three specific eluting solvents (mixture of methanol and sodium chloride and mixtures of acetonitrile and ultrapure water) were used to separate organic compounds into five specific fractions according to their physicochemical properties (anionic and cationic or neutral compounds with various polarity). More than 75 molecules (43 molecules individually studied and a mixture with 43 molecules, including 11 molecules individually studied) including pesticides, pharmaceuticals, endocrine disruptors and polycyclic aromatic hydrocarbons, with various properties were studied, and the results showed that the elution fraction can be predicted for more than 85% of the compounds. This methodology could simplify the analytical chain by reducing detailed analysis on limited categories of compounds, and could be used for a rapid and on-site screening of organic compounds. © CSIRO 2016.
