HYSCORES : Cartographies hyperspectrales appliquées aux écosystèmes coralliens et à leur état de santé.
Provedor de dados: 5
Autores: Ropert, Michel; Mouquet, Pascal; Bajjouk, Touria; Delacourt, Christophe.
En 2013, les résultats des travaux menés dans le cadre des projets "Spectrhabent-OI" (2009-2012), étendus au projet "Bioindication" (2012-2013) ont permis d'illustrer le potentiel important représenté par les nouvelles techniques d'imagerie aérienne hyperspectrale appliquées sur les plateformes récifales de l'île de La Réunion. L'objectif principal du projet HYSCORES (2015-2016) est de consolider ces premiers résultats dans une perspective de mise en œuvre opérationnelle de ces nouvelles méthodes dans le cadre de la DCE (directive-cadre européenne sur l’eau (2000/60/CE)). Pour cela 3 axes de recherche sont proposés : 1) l’étude et l'évaluation de la pertinence de l'indicateur VCH (vitalité corallienne hyperspectrale) proposé en 2012 ; 2) la capacité de...

Au-delà de l'apport de l'hyperspectral dans une dimension descriptive, il a été montré que la combinaison d'indices de couverture algale et corallienne permettait d'envisager l’élaboration d’un indice surfacique d'état, adapté aux plateformes récifales, appelé "vitalité corallienne hyperspectrale" (VCH). L'objectif principal du projet HYSCORES (2015-2016) est de consolider ces premiers résultats tout en évaluant les possibilités de...

After a reminder on the program SYSCOLAG (Coastal and Lagoons Systems), of the regulatory and legislative context in territorial economic planning on the coast, we describe the structure of the developed methodological tool. We clarify then the method according to its three main trunk roads: effects of the activities and uses on the economy of the territory, the effects of the activities and uses on the natural environment and the living environment, the evaluation of the interactions between activities and uses. We apply the method exposed in a frame demonstrator by taking the scenario of the lagoon and coastal territory of the Thau Basin (Hérault). A set of appendices, including in particular evaluation grids are supplied with support for the...

Provedor de dados: 5
Autores: Buchet, Rémi.
Within the European water framework directive (WFD), the status assessment of littoral waters is based both on the chemical quality and on the ecological quality of each water body. Quality elements enabling to assess the ecological status of a water body are, among other things, biological quality elements (phytoplankton, macroalgae, angiosperms, benthic invertebrates, fish), for each of which the member states have developed quantitative indicators. This document is one of the deliverables of a multi-annual study intended to characterize the sensitivity of these biological indicators towards the various anthropogenic pressures exerted on the French Atlantic and Channel coast: ultimately, the goal is to establish a quantitative and predictive...

Autores: Gonson, Charles.
Coastal areas are complex socio-ecosystem where ecological, human and decisional compounds show multiple and reciprocal relationships. Because of the growth of population and tourism sector, coastal areas are permanently threatened through increase of recreational uses and diversification of related activities. To better understand coastal areas functioning, it is necessary to take into account uses and their management. Monitoring data over a ten years period revealed that recreational uses greatly increased especially within Marine Protecting Areas (MPA), during week-end days and warm season resulting to higher and more frequent frequentation peaks. While, practices within MPA are managed to decrease impacts, pressures associated with recreational uses...

The integration of fishing management into the ecosystemic approach has been recommended for many years by international consultative bodies; it is also written into international conventions and agreements. The implementation of the ecosystemic approach involves the development of programmes for monitoring exploited ecosystems in order to measure the effects of management steps. Plotting the results of these observations for operational reasons requires formalizing summary performance indicators.  IFREMER has carried out halieutic observation campaigns for some twenty years along the coasts of France from oceanographic ships and chartered ships. The objective of these campaigns is to produce abundance indices of species that are of halieutic interest....

Autores: Witkowski, Fanny.
Coral reefs are among the most diversified ecosystems; structured by comlexe processese. Yet, spatial organization of the diversity of reef fish communities is not well known. The present study, covering the Marine Protected Area of Pouebo (North-East of New Caledonia), takes part of the AMBIO project from IFREMER, which studies spatio-temporal variations of biodiversity by means of High-definition rotatif underwater video systems. In total 1717 individuals from 25 taxonomic families, 56 genus and 145 species were observed. The derived habitat typology of stations distinguishes five habitat classes, which seem to be highly significant for fish species richness and fish density. Results show that biodiversity increases close to the intermediate and the...

Autores: Brun, Melanie; Soudant, Dominique.
Stakeholders of the Marine Strategy Framework Directive (MSFD) need scientific and technical support to assess ecological status of marine waters and to adopt management actions to achieve the objective of the directive, i.e. “to achieve or to maintain good environmental status in the [European] marine environment by the year 2020 at the latest”. This support involves especially the development of indicators. Studies about the concept of indicator exist, in particular since the implementation of legislations such as the Water Framework Directive (WFD) in Europe. Indeed, they provide a significant source of reports and scientific papers, representing essential information for the implementation of the MSFD. However, the generic nature of the concept of...

The Marine strategy Framework Directive (MSFD) aims to reduce impacts on the marine environment in order to achieve or maintain the good ecological status by using ecosystem approach. The conservation of fish population, exploited or not, is one of the objectives. Criterion 3 of the Descriptor 1 „Biodiversity – Fish” and Descriptor 3 “Commercial species” must qualify the ecological state of these components with regard to their demographic characteristics, in addition to other primary criteria. Many size indicators exist, but in the absence of a threshold value to qualify a condition, this criterion was classified as non-operational in the previous assessment cycle. This study aims to analyze the relevance of size indicators for providing information on...

The scientist community, the fishing organisations and all involved parties show a growing interest in an integrated project management of the sea space exploited by fishing communities. A key to reach such a target is to make available reliable and precise scientist data on the different components of the fishing systems.  For about twenty years, and in its mission to support the development of an integrated management for a sustainable use of marine resources, Ifremer has been organising monitoring campaigns of fishery resources along the shores of France. These campaigns aim at providing abundance indicator on species of interest. They consequently provide an essential knowledge base to characterize and trace the status of exploited fish and...
