The STRADIV project is structured according five work packages (WP) aiming at:

• Establishing an innovation platforms to enhance a multi-stakholders dialogue on biodiversification options and to make easier the integration of biodiversity to cropping systems and the agro-ecological transition (WP1);
• Disentangling the response of biophysical and ecological processes to the management of plant diversity (WP2);
• Understanding trade-offs between ecosystem services with integrative modelling approaches, for in fine establishing optimized rules of management of plant diversity (WP3);
• Integrating the these rules in innovative systems co-designed with farmers and other stakeholder in the framework of a multiple scales approach (WP4);
• Outreaching and capacity building based on results of our project (WP5).

We selected four contrasting types of systems to support our research. They allow an exploration of different types of biodiversification (crop rotation, intercropping with annual crops or perennials) and different levels of structuration of actors interacting with farmers. These types cover both short and long-term effects of plant functional diversity on ecosystem processes (from short cycles in cereal systems to long term effects in perennial cropping systems). (see the presentation of study sites)

• Benchmarking the role of plant diversity and its management on ecological processes;
• Generic rules on plant biodiversity management to increase the efficiency of the systems and the provision of ecosystem services;
• New simulation models dedicated to integrated agroecology;
• Structuring the dialogue with and between actors at multiple scales;
• New methodological framework for the co-design and assessment of innovative biodiversified cropping systems;
• Improved capacity of farmers and other local actors to design alternatives and to improve their capacity to innovate;
• Capacity building of national and international young scientists, scientific publications, MOOCs, international congress on biodiversified systems design.
