In the Bourgogne-Franche-Comté and Auvergne-Rhône-Alpes regions, the PSDR4 projects POEETE and ProSys dealt with the adaptation of agricultural production systems to changes in the environmental, agricultural and social context, focusing on different scales and taking into account the context of reduced inputs and the search for autonomy by introducing legume crops. The processed data come from various approaches: surveys, experimental monitoring, modelling approach... The impact of climate change on the ecophysiology of legume crops was addressed through a model plant, the pea, and two criteria: flowering date and frost stress. To ensure the sustainability of mixed farming operations, new forage mixtures have been tested. Then the ecosystemic services provided by legume crops were studied: precedent effect, nitrogen content and interest in improving the protein autonomy of farms. The prioritization of ecosystem services in the adoption of these crops was studied via surveys of pioneer farmers in the region. Finally, the agroecological transition was studied via questions about the complementarity of mixed farming and livestock production, the performance of cropping systems including legume crops, farmers’ motivations to develop more agro-ecological practices and the study of model farm trajectories.
