Présentation

My current activities on team research interests include (i) investigating the links between land use, root growth dynamics and soil erosion in the mountain environments of Northern Lao P.D.R. and Vietnam in DongCao catchment, (ii) understanding root-soil interactions and crop-intercrop competition processes in rubber tree plantations of NE Thailand and Vietnam, (iii) investigating the long term impact of agricultural practices on the environment and teak plantation, in Northern Lao P.D.R and natural regrows forest Vietnam on DongCao catchement.
