  • ACR’Eau: Cropping systems inspired from conservation agriculture to reduce inputs use and preserve water quality. Funding: Water agency Rhône-Mediterranée-Corse
  • Agro-éco-Syst’N: Identifying agroecological cropping systems of high nitrogen value – specific work on organic cropping systems – Funding: CASDAR
  • CASTOR: Intercropped cover crops supporting the agroecological transition and the reduction of inputs use. Funding: TERRA ISARA
  • Perennial grains:  Grow perennial crops for grain and forage production while providing ecosystems services– Funding: TERRA ISARA & CASDAR
  • Made in AB : Management of weeds in organic agriculture – What do weed management strategies in organic tell us about options to manage weeds without herbicides? – funding Ecophyto EXPE
  • PEI green manure in Provence:  How to manage cover crops without herbicides in cereals, aromatic and medicinal plants in Provence. Funding: European Union and Provence-Alpes-Côte d’Azur Region


Teaching activities

  • Agricultural sciences: theoretical fundamentals, cropping systems, diagnosis (students of Year 3 and apprentices)
