Activités - Fonctions


  • Hayo a obtenu son diplôme d’ingénieur agronome à l’Ecole Nationale Supérieur d’Agronomie de Deventer (Pays-Bas), et un Masters en « Crop Science » à l’Université de Guelph au Canada. Il est docteur en Sciences Agronomiques et Environnementales de l’Université de Wageningen aux Pays-Bas. Aux Pays-Bas il a étudié l’agronomie du maïs et l’agronomie et l’écophysiologie du chanvre.
  • De 1995 à 1997 il a été en postdoc dans à l’INRA de Colmar, où il a mis au point un système expert permettant d’évaluer les impacts environnementaux des applications de pesticides en grandes cultures. Depuis 1997 il travaille à l’INRA de Rennes, où il s’intéresse à l’analyse environnementale des systèmes, en particulier à travers des travaux méthodologiques et appliqués en Analyse de Cycle de Vie des systèmes de production agricoles.
      Membre du comité d'organisation du  colloque international LCA FOOD 2012
