  • Les territoires de la métrologie environnementale. L'exemple de la qualité des rivières en France

    Social studies of science have shown that social perceptions, interests and values influenced the development and the use of technologies. This communication proposes a theoretical framework to assess how social context makes a difference in the way environmental data are collected and processed to make up new environmental monitoring programs. Using examples from the literature, I first contend that the environment is always somehow ambiguous depending on how we look at it. I identify thr...

    Balances de agua y calor en la marisma de Doñana

    / Le marais de Doñana est une zone humide de reconnue importance écologique, principalement comme lieu de pas, élevage et hivernage d'oiseaux européens et africains.

Sa conformation est le résultat du colmatage de l'ancien estuaire de la rivière, et présente une pratique absence de relief avec l'occurrence de procès annuels d'inon...

    La richesse spécifique : un outil pour la prise en compte de la biodiversité dans la gestion de l'espace - Application en Haute Maurienne (Aussois, Savoie)

    Mountain landscapes worked for centuries by human activities, are endangered by agricultural abandonment (open areas become overgrown by shrub fallows or forests). Phytosociological surveys undertaken in Aussois, on 941 plots of 4 m2 each in mowed meadows and already abandoned areas (ancient mowed meadows, shrub fallows and forest edges), shows a global richness of 432 species. This paper proposes that richness should be considered as a five level concept use to compare different vegetation t...

    Une inondation négociée ? Politisation d'un risque naturel sur le Rhône

    Since the 1990s a shift occurred in the policies of flood risk in France. The protection structures that had been prevailing since the 19th century were questioned, and flooding was redefined as an unavoidable and beneficial for the environment. Public policy discourses about risk culture have replaced those of flood risk as an issue of public safety. The policy instruments have also changed. Facilities to encourage residents to live with flooding replaced major dykes building. The thesis que...
