Experience

Senior researcher, I am involved in the « Soil/plant Interactions and biogeochemical coupling » and « C Balance, Soil fertility and global changes » groups of Eco&Sols. I have been working in CIRAD since 1990. My work links the physiology to the agronomy of tropical tree crops, mainly the rubber tree. This work is done with partners from the producing countries. After 3 years in Gabon, 4 years in Ivory Coast and several in France, I contributed to the building-up of the Hevea Research Platform in Partnership (HRPP) in Thailand from 2001 to 2007. I coordinated the platform from 2013 to 2018. In 2018-2019, I was Invited Professor at the Kunming Institute of Botany, Chinese Academy of Science. Back to France, I was Deputy-Director of Eco&Sol from mid-2019 to mid-2021.

 

Qualification and expertise

I have a double qualification in rubber agronomy, from planting practices to tapping systems, and in ecophysiology, on a tree to cover scale. My specific interest and expertise is the influence of tapping the rubber trunk for latex production on the functioning of the whole tree, particularly on carbon and water budget. Latex is a peculiar plant product and this makes the rubber tree a very interesting model to study resource allocation.

I am now extending the scope of my research to environmental and social impacts of tree plantations. Within the HEVEADAPT (ANR 2014-2017) project that I coordinated, we assessed how family plantations can adapt to global changes and keep sustainable. We now focus on forecasting the impacts of climate change and workforce availability on natural Rubber commodity chain in Southeast Asia (FORSEA AFD Project 2022-2026).
