Hazard Laurent - Senior Researcher INRAE Toulouse


I’m currently deputy director of the AGIR Research Unit of INRAE in Toulouse (France). I work on the design of methods to transform agricultural and food practices based on a theoretical framework built on pragmatism philosophy. I'm currently part of the development of two living labs: the AgroEcoLab on the ecological transition of farming systems and the Hmm lab on the redesign of a local food system. I’ve been practicing transdisciplinary research for 15 years.
