Dr Pascal Podwojewski is a director of Research in IRD (Institute of Research for Development) and member of the Mixed Unit of Research (UMR) IEES-Paris – Institute of Ecology and Environmental Sciences of Paris. He has over 38 years of experience in Soil science projects at IRD. He is currently posted in the Institute of Arid Regions in Medenine (south Tunisia). Prior to that, he has been posted in 4 different countries and continents (New Caledonia, Ecuador, Vietnam and South Africa) for leading research projects in soil mapping and soil type characterization in relation with major natural changes or degradation by human activities (overgrazing, fire, cultivation, erosion on sloping land). He is specialist of soil biochemical properties, detachment processes and land degradation related with global changes.

He is currently in charge in South Tunisia of a programme to improve water retention of degraded sandy soils in arid environment applied for rain fed olive tree plantations. IPBES Land Degradation and Restoration assessment for IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) – Review editor for the Chapter 1 and co-author of chapter 4 Status and trends of land degradation and restoration and associated changes in biodiversity and ecosystem functions.
