We think that global problems can only be solved by strong international relationships. Therefore we developped international collaboration involving student exchange, which is highly beneficial in terms of scientific education.


Since 2008, PSG collaborates with the Scientific and Technological Bioresource Nucleus (BIOREN) at the Universidad de la Frontera in Temuco (Chile). Our students benefit from regular exchange. The collaboration under the framework of two EcosSud projects has led to two PhD theses carried out in co-tutelle and many co-authored papers.

Since 2014, PSG collaborates with the Global Centre for Environmental Remediation  at the University of Newcastle (Australia) and the College of Agriculture & Natural Resources at the University of Delaware (USA) under the framework of the Australian Research Council funded project ‘Carbon Corundum’.

In 2015, PSG established a collaboration with Landcare Research in Lincoln (New Zealand) under the framework of the project ‘Management options for increasing soil carbon under grasslands’ funded by the Newzealand Ministry for primary industries.

A collaboration with the National Ecological Observatory Network (NEON) in Bolder, USA allowed PSG to address global large scale ecological processes related to climate and landuse changes. Under the framework of this collaboration we share best practices with regards to the establishment and governance of large scale integrated research infrastructures.

PSG is part of the international soil warming network coordinated by the University of California in Berkley (USA). We collaborate with this institution in terms of technical expertise and promotion of this kind of field experiments.

PSG has a strong long lasting collaboration with the Institute of Soil Science at TUM in Munich, Germany on the molecular characterisation of soil organic matter. Recently, we shared master and PhD students.

In 2017, PSG established a collaboration with the Institute of Environment and Sustainable Development in Agriculture at CAAS in Pekin, China about the analyses and understanding of nanoscale controls on biogeochemical cycling of elements.


We have an on-going collaboration with the Agroecologie lab at INRA Dijon concerning the impact of microbial diversity on soil organic matter dynamics and soil processes.

Concerning the microbial players implicated in N2O emissions we collaborate with the research unit Ecologie microbienne à Lyon.
