Activities

Research

I work on the design of agroecological cropping systems in livestock farming territories. My research project is organized into three parts:

• Diversification of cropping systems on a supra-farm scale, based on the assumption that this scale makes it possible to mobilize agroecological levers that are not, or only to a limited extent, possible on the scale of an individual farm.
• Transfers within a territory or between neighboring territories, particularly in terms of fertility. Territorial specialization generates disparities in the production of fertilizing organic matter, with areas that are densely populated with livestock being able to produce a surplus while others, such as areas specialized in crops, have a deficit.
• Understanding innovation and the conditions of its production. In this section, I seek to understand and describe the existing innovation and the conditions that led to its realization.

Prior to this, I did my thesis at UMR SAS and the Centre Technique Interprofessionnel des Fruits et Légumes (CTFIL) from 2019 to 2022, on the environmental performance of organic vegetable farms, using the life cycle assessment (LCA) method.

Ongoing projects

• AMPERA : Metabolic and landscape approach for a territorialized agro-ecological transition in livestock farming (coordinated by V. Viaud and C. Thenail) (2023-2027)

Completed projects

• MESCLUN DURAB : A digital tool to link sustainability assessment and the (re)design of innovative vegetable production systems (coordinated by K. Morel) (2023-2027)
