Current Research Topics

My main topic is to understand the relation between herd management and crop rotation management. I focus on mixed / integrated farms. At BAGAP research unit, we modelled decision on crop rotations over several farming systems. It allowed us to simulate (thanks to Capfarm modelling tool) agricultural landscapes according to their composition in farming systems. From this research, I produced — with Audrey Alignier (UMR BAGAP) and Estelle Meslin (MFR Janzé) — a serious game to introduce agricultural landscape management to students.

I develop tools to differentiate mixed/integrated farms on their diversity of production, their integration between crops and animal, and their interactions with neighbors. I use these tools to explain economic and environmental performances of farms.
