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

Abstract : To reduce the negative impacts of agricultural systems, the agro-ecological transition first calls for the use of greater cultivated biodiversity. Such diversification can be implemented at the field scale, mixing different species, or different varieties of the same species. We discuss the advantages of this intra-field diversification by developing 5 examples: (1) varietal mixtures of wheat in France, (2) rice populations in YuanYang, (3) oilseed rape associated with service plants, (4) mixtures of forage species and (5) cereal and 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) breeding activity, and (iv) the impact of these stands and practices on associated wild biodiversity.
