AIM

• identify the levers and the spatial and temporal conditions for the enhanced integration of legumes into agricultural systems at different scales;
• examine the consequences of this integration on nitrogen supply, crop behavior and sector organization;
• mobilize the tools and databases available to assess the contribution of legumes to the development of OA.

MEANS

To achieve these objectives, this consortium will call upon the expertise of researchers from different domains: ecophysiology, agronomy, plant health, modeling, biogeochemistry, livestock production, and the economics of related sectors and organizations, in order to:

• build a future project that will make it possible to assess the different scenarios for increasing the use of nitrogen fixing legume species;
• draw up a scientific overview of the symbiotic fixation capacity of the different agricultural species in OA, depending on their growth and pedoclimatic conditions.

A European partnership (FiBL Switzerland) will provide additional expertise in terms of the sustainability of food systems in OA as well as enhanced value for the construction of the future project.
