To understand, anticipate and assess the impacts of global changes on the ecosystem services provided by human-made or natural ecosystems in order to enable their sustainable and multi-functional management. Reflect on the clusters of such services (where they are numerous and interdependent), study them as such and question their conceptual relevance.

To meet this challenge, it is essential to work in an interdisciplinary way, in order to understand not only the dynamics of each function/service, but also their interactions. We are particularly interested in: (i) the characterisation of mechanisms and patterns (state, value and vulnerability of Ecosystem services) at different spatiotemporal scales and their relationships (conflicts and synergies); (ii) the assessment of the impact of changes and the response of ecosystem services in order to evaluate the optimal state of the multifunctionality of ecosystems and identify levers for action (e.g. vegetation management scenario); (ii) the development of concepts and tools adapted to the sustainable management of ecosystem services, especially when they are numerous and interdependent (often referred to as conflicts and/or synergies).

The main worksites are located in the south of France (road embankments; Camargue), in French Guiana (tropical forest), Central Africa and Mexico (underground services), and in central and southern China (restoration). Our work is based on: in situ measurements and observations of functional services/traits (morphology, anatomy, biomechanics and biochemistry); modelling and simulation of networked ecosystem processes (Capsis platform, DORIAN Ecoservet model); experimentation on biotic and abiotic processes (under controlled conditions in greenhouses, rain simulation, marking with stable isotopes, etc.).
