Innovation systems and sustainability assessment

Interactions with farmers and local policy-makers for the development of legume crops, microbial inoculants and technical practices in reference agro-ecosystems; identifying possible innovation systems for the legume alternatives with description of past innovation trajectories by case studies; evaluation of the sustainability of the cropping system with legumes by means of indicators taking into account their economic performance and ecological services.

Coordinated by M Dulcire (CIRAD-INNOVATION)
