Résumé
The French MAB committee (MAB France) animates and consolidates the national network of BRs, and puts it in touch with the French and international communities interested in the MAB programme. This chapter describes the functioning of the French national network of BRs. First, we present MAB France and highlight its recent evolution and its vibrant innovations over 15 years. Then, we dwell on the French BRs. Where and what are they? When and why were they created? How do they work? Finally, in a third part we focus on their added value in the national landscape of protected areas and sustainable management of nature and its resources. In conclusion, we highlight their contribution to the implementation of a social-ecological stewardship based on ecological solidarity. The remaining challenge is to define an effective participatory approach that brings together public action and local collective actions. The unprecedented recognition enjoyed by the World Network of BR and MAB programme in recent years - by both national and local public authorities - augurs a new dynamic with hope for the future of the biosphere.
