Presentation of the research unit

The joint research unit LEPSE (Laboratoire d’Ecophysiologie des Plantes sous Stress Environnementaux) gathers staff from the French Agricultural Research Institute INRA (Institut National de la Recherche Agronomique) and the Center for higher education in Agricultural Sciences, Montpellier SupAgro. Most of the scientific staff is ecophysiologists and bioclimatologists. LEPSE was founded in 1993 to produce methods and knowledge to help maximising crop production with less input, essentially water. This objective was initially assigned in the context of the necessity to limit water use by agriculture. Ongoing climate change, with global temperature elevation, increased probability of heat waves and drought episodes have led us to widen our domain of research.

Organisation

The whole unit is divided into three scientific teams :

ETAP group :« Efficience de transpiration et adaptation des plantes aux climats secs»
Email group leader : Thierry Simonneau

MAGE group : « Modélisation et Analyse de l'interaction Genotype Environnement »
Email group leader : François Tardieu

SPIC group : « Stress Environnementaux et Processus Intégrés»
Email group leader : Denis Vile
