In south east Asia, Eco&Sols is involved with the joint « Hevea Research Platform in Partnership » (DP HRPP) and the Joint International Laboratory “« Land Use changes and Soil Ecosystem Services » (LMI Luses).
These two facilities study the 3 research themes of Eco&Sols, focusing in particular on the functioning of the rubber tree ecosystem in Thailand. Eco&Sols is involved in setting up simple field indicators to gain a better understanding of the relationship between biodiversity and function in agrosystems in Laos and Vietnam, and soon in Cambodia.
Eco&Sols is mainly involved in the HRPP Agronomics, physiology and environment activity. Since 2015, research has been organised around the National Research Agency Heveadapt project which studies how biophysical factors interact with socioeconomic factors to determine the vulnerability of family-run plantations and how they can adapt to global changes.
Research is based on a network of observatories and experimental sites, in particular 3 sites equipped with a high level of instrumentation to measure carbon and water flows and ecophysiological parameters, 3 physiology and ecophysiology laboratories, long term trials on the adaptation of rubber clones to water stress (GHRYD project) and on the use of fertilisers (Yara project). This research in experimental sites is complemented by field studies to monitor the effect of transitions (forest to plantation or crop to plantation) and the long term effect of plantations, in particular on the soils.

LUSES joint international laboratory
LUSES « Dynamic of Land Use changes and Soil Ecosystem Services » is a joint international laboratory with 7 Asian partners in Laos, Thailand and Vietnam and two French Research Institutes, the IRD and CIRAD.
This laboratory sets out to consolidate the research capacities (education, equipment, training) of its partners on the environmental impact of agriculture. This is an integrated approach based on a multi-disciplinary team (soil scientists, microbiologists, soil and water biologists and agronomists) and a network of institutes in south east Asia and the IRD, centred on soil-plant-water interactions in cultivated land.
The current news about the laboratory can be found on the LMI Luses facebook page

Between 2012 and 2015, 15 joint courses were organised by Eco&Sols in Laos, Thailand and Vietnam involving more than 290 partners. Three courses are scheduled for 2016:
- Measuring soil microbial activity using MicroRespTM
- Statistical ecological analyses
- Writing an article in English
