At the interface between systemic agronomy, ecophysiology and functional ecology, my research focuses on the functional role of herbaceous plants (individual or plant community) as a key component to understand the functioning and dynamic of agroecosystems and their agronomical and ecological properties. One of the central hypothesis of this work is that functional dimension of plant diversity is essential and complementary to either taxinomic or ‘sector’ (production, valorization and end markets) dimensions to drive the diversification and conception of cropping systems less dependent on external inputs, less sensitive to climatic hazards, and more favorable to soil fertility (agroecological conceptual framework).”
