Scientist at INRAE / SAS Phone: (+33) 2 23 48 57 09 Email: hayo.van-der-werf@inrae.fr Address: INRAE Centre Bretagne-Normandie, UMR SAS, 65 rue de St-Brieuc, CS 84215, 35042 Rennes Cedex, France Fields of expertise: Environmental assessment, agroecology Keywords: Life cycle assessment, ecosystem services, agroecology, organic agriculture

Research

My research topic is the environmental assessment of agricultural production systems. I mainly use life cycle assessment methodology. I am particularly interested in organic agriculture and more generally in agroecological systems, and in ways to assess both the environmental impacts and ecosystem services supplied by agricultural systems.

Current project

• ACV-Bio: Life cycle assessment of products of French organic agriculture (2017-2020)
• PerMABio: Environmental performance of organic vegetable farms (2019-2022)
• PerFEBio: Performance of livestock farms aimed at restoring the biodiversity of agricultural landscapes (2019-2022)
