Composante essentielle de tous les êtres vivants, l’eau est aussi un milieu de vie pour certains d’entre eux. Elle circule sans cesse, des précipitations vers les eaux de surface (cours d’eau, rivières, fleuves, lacs, etc.), la végétation (sauvage et agricole), les eaux souterraines (nappes), les mers et les océans. Sous l’effet des activités humaines, elle fait l’objet de nombreuses pollutions susceptibles d’affecter la biodiversité et la santé humaine. Protéger la ressource en eau constitue donc un enjeu majeur. Le Service des données et études statistiques (SDES) et l’Office français de la biodiversité (OFB) s’inscrivent dans cette démarche en informant et sensibilisant régulièrement l’ensemble des acteurs sur les enjeux liés à la préservation de l’eau et des milieux aquatiques.
Water and aquatic environments - Key figures - 2020 edition
An essential component of all living beings, water is also a living environment for some of them. It circulates constantly, from precipitation to surface water (rivers, streams, lakes, etc.), vegetation (wild and agricultural), underground (groundwater), seas and oceans. Many kinds of pollution, resulting from human activities, impact water quality and can, in turn, affect biodiversity and human health. Protecting water resources is therefore a major ongoing concern.
The Data and Statistical Studies Department (SDES, Service des données et études statistiques) and the French Biodiversity Agency (OFB, Office français de la biodiversité) play a major role in raising the awareness of all actors and giving regular information about key issues related to the preservation of water and aquatic environments.
Aiming at the wider public, this collection of 48 selected indicators, with their expert analyses, presents the state and evolution of water and aquatic environments, the major pressures that human activities place on these environments, as well as the means implemented to protect them.
