Main fields of research and expertise

Over the last 30 years, Jean-Luc Maeght worked at national and international levels, in several countries (France, Mauritania, Senegal, Thailand, Lao PDR), in multi-disciplinary teams, in agronomy, soil conservation, biophysic, ecology and natural resources. He worked also on scientific instrumentation and experimental techniques on root images acquisitions. His key qualifications are: soil science and biophysic (physicochemical characteristics of the soil, hydrological assessment, study of degraded and submerged soil), plant ecology (rice crop, rubber tree, teak tree, roots development in Forestry and Agroforestry), and engineering (root images process, data acquisition and automatic transfer – use of data logger and sensors). His current activities within team research interests include (i) investigating the links between land use, root growth dynamics and soil erosion in the mountain environments of Northern Lao PDR and Northern Vietnam, (ii) understanding root-soil interactions and crop-intercrop competition processes in rubber tree plantations of NE Thailand and agroforestry system in France, (iii) investigating the long term impact of agricultural practices and drought on under teak plantation, in Northern Lao PDR and on land use change from cultivated to natural re-growth vegetation in Northern Vietnam.
