Etat d’avancement de la mise en place des Plan de Protection de l'Atmosphère (PPA) 8 mars 2013 (mis à jour le 24 septembre 2015) Afin de mieux répondre à l’urgence sanitaire causée par la pollution atmosphérique dans plusieurs zones du territoire national, une dynamique de mise en révision des Plans de Protection de l’Atmosphère existants et d’élaboration de nouveaux Plans a été lancée dans toutes les zones polluées de France. A l’heure actuelle : On compte 36 PPA en France, dont 28 signés 1 PPA sont en cours de révision 7 PPA sont en cours d’élaboration 47% de la population française est couverte par un PPA

Première utilisation du sol, devant l'agriculture et loin devant l'urbanisme, la forêt couvre 45 % du territoire aquitain. La région se caractérise par la domination d'une essence, le pin maritime. Celui-ci couvre plus de la moitié de la surface forestière régionale. Outre sa valeur patrimoniale, cette forêt génère une activité économique qui représente environ 3 milliards d'euros. Ce secteur forêt-bois est donc un formidable gisement d'emplois, principalement en milieu rural. Cet espace occupé par la forêt attise néanmoins des convoitises pour différents types d'usage: l'urbanisation, les installations photovoltaïques ou encore l'agriculture.

Description of the attributes for the time-series of sea internal energy for the last 20 years for the Mediterranean basin and for each NUTS region along the coast.

This gridded product visualizes 1960 - 2014 water body ammonium concentration (umol/l) in the North Sea domain, for each season (winter: December – February; spring: March – May; summer: June – August; autumn: September – November). It is produced as a Diva 4D analysis, version 4.6.9: a reference field of all seasonal data between 1960-2014 was used; results were logit transformed to avoid negative/underestimated values in the interpolated results; error threshold masks L1 (0.3) and L2 (0.5) are included as well as the unmasked field. Every step of the time dimension corresponds to a 10-year moving average for each season. The depth dimension allows visualizing the gridded field at various depths.

The Copernicus Marine Service (or Copernicus Marine Environment Monitoring Service) is the marine component of the Copernicus Programme of the European Union. It provides free, regular and systematic authoritative information on the state of the Blue (physical), White (sea ice) and Green (biogeochemical) ocean, on a global and regional scale. It is funded by the European Commission (EC) and implemented by Mercator Ocean International. It is designed to serve EU policies and International legal Commitments related to Ocean Governance, to cater for the needs of society at large for global ocean knowledge and to boost the Blue Economy across all maritime sectors by providing free-of-charge state-of-the-art ocean data and information. It provides key inputs that support major EU and international policies and initiatives and can contribute to: combating pollution, marine protection, maritime safety and routing, sustainable use of ocean resources, developing marine energy resources, blue growth, climate monitoring, weather forecasting, and more. It also aims to increase awareness amongst the general public by providing European and global citizens with information about ocean-related issues.

Description of attributes for time series of annual average sea level (units: mm) from tide gauges over periods of 50 years (1963-2012) and 100 years (1913-2012), to characterize and assess average annual sea-level rise relative to the land.

Specification of the desirable and recommended product attributes for generating spatial layers of sea-level trend (units: mm/year) from tide gauges over periods of 50 years (1963-2012) and 100 years (1913-2012), to characterize and assess average annual sea-level rise at the coast.

Avec près de 1,4 millions d’hectares de surface agricole utilisée et 100 000 ha d'estives, l'agriculture occupe en 2010 près de 35 % du territoire aquitain. Par son assolement diversifié, elle contribue largement à la diversité des paysages et la structuration de l'espace régional. Toutefois, au cours de la dernière décennie, plus de 96 000 hectares ont quitté le giron de l'agriculture...
