Rhone Basin Long Term Environmental Research Observatory (RBLTER)

An observatory on hydrosystems & social dynamics linked to water

The Rhone Basin Long Term Environment Research comprises Observatory and / or Experimental Sites. It is the support of research programmes that provide elements of knowledge to stakeholders and to public decision-makers, in the field of sustainable management of rivers and watersheds.

A researchers and partners network

  • a scientific label of the CNRS
  • 23 universities, schools or research organisations
  • 345 researchers


It aims to provide to decision-makers with a methodology to evaluate the effects of watersheds rehabilitation or restoration on river hydrosystems, in terms of biodiversity, sustainability (lasting effects), ecological services and potential uses

4 research themes crossed on experimental sites …

  • Climatic change and resources
  • Flows, forms, habitats, biocoenocis
  • Pollution flows, ecotoxicology and ecosystem
  • Social observation of the river governorship

A forum of exchange

  • Co-ordination of scientifc and
     technical workshops
  • To look for a correct adequacy  between developed research programmes and social concerns expressed by professionnals
