AIM

The aim of this project is to test and to develop, on the basis of data collected at the national scale, an analysis framework of the effects of the spatial expansion of OA on different components
of biodiversity and services provided, in order to evaluate the relationships between ecological, economic and agronomic performances in OA.

More specifically, it involves:

• the proposal of a common framework for the analysis and quantification of performances, explicitly integrating the functions and services
provided by biodiversity;
• an assessment of the ability of this analysis framework to evaluate the synergies and antagonisms between performances along a gradient of the proportion of OA in the landscape;
• the identification of other landscape characteristics that make it possible to promote synergies between performances and to optimize
multifunctionality.

MEANS

This consortium brings together ecologists, agronomists and economists, and uses datasets resulting from long-term studies in a handson production context (approximately 200 plots throughout France) for several types of crops: cereals, rape, grapevines and apples.
