  • Ces travaux ont été réalisés dans le cadre de la Directive Territoriale d'Aménagement et de Développement Durable (DTADD) portée par la Préfecture de la région ex-Aquitaine. La partie I de ces travaux porte sur les valeurs du massif forestier des Landes de Gascogne. Le massif est dépositaire d’importantes valeurs et fonctions non marchandes d’intérêt général notamment : paysagères, naturalistes, hydrologiques et climatiques. Ce rapport explique également que les modes de valorisation du territoire, autres que ceux liés à la production de bois d’œuvre et d’industrie, interfèrent étroitement avec la présence même de la forêt de production : l'activité touristique, l'arrivée de nouveaux habitants et l'économie induite, ainsi que le foncier forestier.

  • Created in 2015, it follows on from the RESCO launched in 2009, and REMORa launched in 1993. In 2015, the structure and operation of the former RESCO network was used to implement planned monitoring of oysters. More specifically, the sentinel batches used by the network, representing 3 age classes (6 months, 18 months of the previous year and 30 months of the previous year) are monitored regularly (frequency: bi-monthly or monthly). throughout the year at 12 national sites (corresponding to former RESCO sites). At each passage, counts are made to assess the mortality rate, and different types of laboratory diagnostic tests will be performed: - initially, the new spat batches (Ifremer Standardized Spats) will undergo specific PCR analyzes to search for potentially present infectious agents (OsHV-1 and Vibrio aestuarianus) but also non-specific analyzes (histology, classical bacteriology) for the possible detection of other pathogenis agents ; - for the detection of emerging diseases, the first dying batches detected for each age group, for each site, will undergo specific laboratory (OsHV-1 and Vibrio aestuarianus PCR) and non-specific (histology) diagnostic tests in order to detect as early as possible emerging diseases in these sentinel batches; - for the detection of exotic diseases, in the absence of a hierarchy of exotic diseases being available for oysters, it was decided to monitor the parasite Mikrocytos mackini because infection with this parasite is regulated at European level, on one of the RESCOII sites (Loix en Ré) previously identified as a site at risk with respect to the introduction of this parasite. In addition to these mortality follow-ups and the laboratory diagnoses, each site is equipped with a probe to allow it to gather environmental parameters (temperature, pressure, salinity) at high frequency. The various results are stored in the Quadrige² database, and are available for the various actors involved. The network is closely linked to a dedicated website which allows the dissemination of objectives, protocols and results, and which will be updated every month. In parallel, newsletters summarizing the results obtained are sent by e-mail every month to the State services.

  • L'atlas départemental du risque incendie de forêt a pour but de réaliser une cartographie des aléas et enjeux avec une précision suffisante pour déterminer le risque incendie de forêt l'ensemble des communes du Lot-et-Garonne, et ainsi déterminer les communes pour lesquelles un Plan de Prévention du Risque Incendie de Forêts (PPRIF)serait nécessaire.

  • This dataset is the coastal zone land surface region from Europe, derived from the coastline towards inland, as a series of 10 consecutive buffers of 1km width each. The coastline is defined by the extent of the Corine Land Cover 2018 (raster 100m) version 20 accounting layer. In this version all Corine Land Cover pixels with a value of 523, corresponding to sea and oceans, were considered as non-land surface and thus were excluded from the buffer zone.

  • Successive infections with Vibrio harveyi were conducted in two populations of the European abalone in order to examine which genes may be involved in improved survival to the disease in the St. Malo population.

  • Shom is the national referent for the level of the sea in situ on all areas under French jurisdiction. In this capacity, he assures under the acronym REFMAR different coordination functions in the collection and dissemination of public data related to water level observations, in order to promote their use in multiple applications within the framework of international recommendations.
