CNR model

Water resources and biodiversity

Confronted by the outlook of diminishing water resources and the depletion of biodiversity, CNR acts with its partners to promote thriftier use of the Rhone’s water and preserve the river’s ecological diversity.

Sharing water resources must remain balanced to ensure that the Rhone remains a public good accessible to different uses and a vector for territorial development. CNR develops different types of action in order to hand on an enhanced river to future generations:

passe-a-poissonsRestoring the ecological quality of the Rhone

Rehabilitation of the bypassed sections of the Rhone of Péage-de-Roussillon, Montélimar and Donzère-Mondragon in view to restoring 20 oxbows from now to 2018.

Restoration of the branches of Arméniers (Vaucluse), already included in the river contract of the Meyne and the wetlands of the Rhone.

favoriser-une-agriculture-durableEnriching biodiversity

The construction of fish passes at Sauveterre, Rochemaure, Le Pouzin and Vallabrègues, in conformity with the migrating fish management plan.


Actions performed with associations, especially the Fédération Rhône-Alpes de protection de la nature (FRAPNA) and the Ligue de protection des oiseaux (LPO) to make new generations aware. 

Developing the programme “Bees and Company” programme to preserve bees and other pollinating insects that guarantee biodiversity.

Promoting sustainable agriculture

Partnerships have been forged with the agricultural world to develop innovations to ensure thriftier water use.

Support is given to environmental research:

  • The Rovaltan Foundation for Scientific Cooperation for the ECOTOX centre: multidisciplinary research programmes are performed to understand the fate of contaminants in the environment  
  • The Alternative and Organic Techniques (AOT) platform in Drôme: a farm dedicated to experiments with multi-crop and innovative systems

CNR’s land and the environment

The implementation of the Green and Blue Corridor to preserve the ecological continuity of the Rhone for plant and animal species.

The deployment of an environmental management plan of the land of the concession in view to harmonising the uses made of it.

Didier Guillaume
President of the Drôme General Council

CNR assists us in our strategic territorial projects. Thus it is involved in a major project, the Rovaltain toxicology and ecotoxicology centre. This European scale research centre studies the interactions between the environment and human health. CNR’s support helps Drôme to enter the knowledge-based economy on a lasting basis.
