Current research topics

The main topic of my research is the design of biodiversity-based cropping systems. I am interested in understanding the feedbacks loops between crop diversity and soil functioning. Climate change is projected to show increasing frequency and intensity of ecosystem disturbances. Such events could affect crop yield directly or indirectly through complex interaction with soil processes. Meanwhile, a growing body of literature is pointing out the benefits of crop diversification to face climate change. Ecological theories can be mobilized to explain such complex interactions. Depending on functional plant traits, plant species could alter differently abiotic and biotic soil conditions that in turn affect growth of other conspecific and heterospecific individuals in that soil after disappearance of causal plants. These complex interactions were conceptualized in the Plant Soil Feedbacks. In agriculture, plant-soil feedbacks are exploited in the form of crop rotation.

Accordingly, my research topics are:

• evaluation of crop diversity on soil functionning based on rhizopshere effects
• effects of crop diversity on soil microbial resistance on soil respiration and nitrification
• agroforestry as an example of biodiversity based system.
