Les indicateurs de biodiversité pour accompagner les agriculteurs : embarras du choix ou pénurie ?

National audienceTo reduce the negative impacts of agricultural systems, the agro-ecological transition first calls for theuse of greater cultivated biodiversity. Such diversification can be implemented at the field scale, mixingdifferent species, or different varieties of the same species. We discuss the advantages of this intra-fielddiversification by developing 5 examples: (1) varietal mixtures of wheat in France, (2) rice populations inYuanYang, (3) oilseed rape associated with service plants, (4) mixtures of forage species and (5) cerealand legume intercrops for grain production. We discuss the benefits conferred by this diversification on:(i) optimization and stabilization of production, (ii) interactions with cultural practices, (iii) breedingactivity, and (iv) the impact of these stands and practices on associated wild biodiversity
