I’m a PhD student at Sorbonne University (SU) and the Institute of Technology of Cambodia (ITC) and my PhD focuses on the ecosystem services delivered by biodiversity (here termites because they are the most impressive soil engineers in Cambodia building large scale mounds) in paddy fields in the long term observatory of Chrey Back,in Cambodia. First I considered their impacts on soil fonctioning, with a focus on soil physics and organic matter dynamics, and second I looked at the utilization by the population, from the utilization of termite mound soil as amendment to the consumption of plants for medicinal purposes.
