The eU is undergoing a fundamental change in the aims for its agriculture and food systems, with a significant emphasis on meeting sustainable goals and reducing reliance on imports from outside europe. The Horizon 2020 reMiX research project (n. 727217) collaborated with farmers and additional stakeholders such as agricultural advisors to analyse and optimize the performance of intercropping based on species mixtures, mainly cereals associated with grain legumes, to design productive, diversified, resilient and environmentally friendly cropping systems that are less dependent on external inputs, or more productive in organic farming.
