Research director: Biogeochemistry, Soil science, Grassland ecology, Agroecosystem, Ecosystem-sustainability


Dr. habil. Abad CHABBI, Research Director at the INRA, is a plant ecologist and soil biogeochemist. He worked at the Louisiana State University, USA; the Faculty of Environmental Science in Cottbus, Germany; the University of Pierre & Marie, Curie (UPMC), France; and the INRA research council where he has been leading the national Observatory for Environmental Research-Agro-Ecosystems, Biogechemical Cycles and Biodiversity ( since 2009. His areas of expertise are ecology and soil biogeochemistry. He has worked on the ecology and biogeochemistry of land-water interfaces, the effect of plant on soil organic matter dynamics and ecosystem responses to disturbance. His current research centers on understanding the link between soil carbon sequestration, nutrient availability and stoichiometry in the Plant-Soil System, plant diversity and the influence of land use management and climate change may have on these dynamics.

During his career, Dr. Chabbi has coordinated a number of pluridisciplinary projects at a national and international level, chaired and organized numerous international symposiums and edited books and several special issues of leading international journals. He is the Associated Editor of AoB Plants Oxford Journals, the Journal of Agricultural Research,member of the Editorial Board of Water Air and Soil Pollution Journal (2009-2012) and reviewer of dozens of peer review journals of environmental sciences. He has presented a number of keynote seminars around the world.

Currently, Dr Chabbi is a member/expert of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, the Chinese Academy of Science, the German Research Science Foundation (DFG), the Hercules Foundation (Hercules stichting) Belgium, the Biotechnology and Biological Sciences Research Council (BBSRC) UK, the Natural Environment Research Council (NERC) UK and of the European commission (DG Research & Innovation and DG Agriculture and Rural Development).

Dr. Chabbi is the coordinator of two strategic European FP7 projects: “EXPEER” ( and “ANAEE” ( Since April 2013 he has also been leading the C2 component of the Ecosystems Task at GEO (Group on Earth Observations).
