CNR model

Sustainable agriculture

In additional to its historic mission of providing irrigation, CNR helps agriculture to face new environmental challenges and climate change. Its action aims at favouring agriculture that is thriftier with water and energy.

Concessionary of the Rhone for its three uses (hydroelectricity production, navigation, irrigation), CNR is a historic partner of agricultural with the construction of more than 40 water intakes along the river to provide irrigation for 120 000 hectares land. Committed to green growth, CNR helps farmers to make their agriculture more sustainable. This is one of our actions in the framework of our Missions in the General Interest to which we devote more than €5 M and it is one of our 9 commitments in favour of energy transition and the climate.

Our approach has 3 main objectives for defining a new agroecological corridor in the Rhone Valley :

  • Water: water saving and irrigation projects
  • Energy: energy management of irrigation systems
  • Soil and biodiversity: development of agro-ecology through experimentation and innovation on the farmland of our concession.

Recherche agricole et environnementale

Agricultural and environmental research

CNR is a partner of the AOT platform (Alternative and Organic Techniques), located on the site of the experimental farm of Etoile-sur-Rhône, in Drôme. Driven by the Drôme Chamber of Agriculture, this 20 hectare space is dedicated to experimenting and demonstrating multi-crop and innovative agricultural.Another partnership has been forged with the Fondation Rovaltain, for its high level research centre operating at national and international scale, specialised in ecotoxicology – the ECOTOX centre.

Signature d'un accord-cadre CNR

Agroecological transition

In March 2015, CNR signed a partnership agreement with the Rhône-Alpes Regional Chamber of Agriculture (CRARA) and ISARA-Lyon, a school specialised in agricultural, food, and environmental engineering, to assist agroecological transition in the Alpes. This partnership responds to national objectives to produce differently, preserve biodiversity and ensure the economic performance of farms and sectors.

With this agreement, CNR and its partners are pursuing three major directions :

  • Contribute to taking climate change into account and assisting the adaptations required for agriculture by optimising water and energy resources
  • Promote sustainable and diversified agriculture in relation with the development of the Rhone Valley and, particular, in synergy with tourism development
  • Preserve the biodiversity and the ecological continuity of the corridor formed by the Rhone through agricultural practices and production systems with high environmental performance.

To reach these objectives, it is important to carry out experiments and innovate in order to develop new agricultural systems for the benefit of the territory crossed by the Rhone.

CNR, partner of the Tech&Bio show

CNR was presented for the first time at the Tech&Bio show, a biennial event for showcasing alternative and organic techniques, organised by the Drôme Chamber of, on 23 and 24 September 2015. On this occasion, it gave awards to 15 organic farmers, for their economic, social and environmental performances
