Leveraging TREE benefits in socio-ecosystems under extreme weatHer events with local knowledge: a modelling aPproach

The Marie S. Curie Postdoctoral Fellowship (MSCA-PF) programme is a highly prestigious renowned EU-funded scheme. It offers talented scientists a unique chance to set up 2-year research and training projects with the support of a supervising team. Besides providing an attractive grant, it represents a major opportunity to boost the career of promising researchers.

Research laboratories in Brittany are thus looking for excellent postdoctoral researchers with an international profile to write a persuasive proposal to apply for a Marie S. Curie Postdoctoral Fellowship in 2026 (deadline of the EU call set on 9th September 2026). The topic and research team presented below have been identified in this regard.

Environment and Geosciences (ENV)

Nature-based solutions, urban forestry, agroforestry, structural equation modelling, beliefs, values, functional ecology

Nature-based solutions, solutions that involve coexisting with nature, have recently gained attention by many international organizations (FAO, IUCN, IPCC) because they can address the impacts of dramatic extreme weather events in urban and agricultural lands while supporting sustainable development. To achieve resilience towards extreme weather events, human-nature relationships have to be recoupled within the whole nexus of socio-ecosystems (ecological-governance-society). Faced with this challenge, the interfaces between cities and rural areas are crucial because of the interdependencies between socio- economic and ecological systems for educational, food, transport and equity. Moreover, nowadays people have limited experience with nature (“shifting baseline syndrome” and “extinction of experience”), which in turn could limits sympoietic relationships to gain new alliances between human and non-human, especially in the urban milieu. Due to many functions related to ecosystem services, these alliances must preserve the soil functioning for climate adaptation and attenuation. Our research question is to evaluate how trees, as a symbol and recurrent feature in urban and agricultural lands, and conveyor of beliefs and values, could lever nature-based solutions in socio-ecosystems.

We hypothesize that the presence of trees and their role in the resilience of the soil microbial community and its functioning could be a trigger (or an indicator) of the importance of biodiversity by various stakeholders. Our approach is based on functional ecology and microbial ecology. Along with an experimental determination of the role of tree and understorey vegetation and their traits in the functioning of urban and agricultural environments, structural equation modelling will be used to (i) capture the local knowledge of various stakeholders, and (ii) explore the different causal patterns linking soil microbial resilience to functional diversity. This approach will also include a group discussion to reconnect people with the need to protect soils and biodiversity by co-learning based on data-driven approach. This project is supported by the POPSU project head, Prof. Dr Romain Pasquier (political sciences) and local political authorities and stake-holders.

The Postdoctoral Fellow will be supervised by Edith Le Cadre as main supervisor (full professor of agronomy) at Institut Agro and by secondary international supervisors (see secondments). This project is supported by the POPSU project head, Prof. Dr Romain Pasquier (political sciences) and local political authorities and stake-holders, and applied statistics experts (Pr Mathieu Emily) providing a nurturing environment for transdisciplinary approaches of Nature-based solutions.

SAS joint research unit (Soil AgrohydroSystem Spatialisation) focuses on interactions between agriculture and the environment, from the scale of a field or livestock building to that of a watershed or agricultural landscape (of a few thousand hectares). Our research focuses mainly on agricultural contexts with livestock systems. For more informations: https://eng-umrsas.rennes.hub.inrae.fr/

Rennes and Brittany (North west France), with mobility to the University of Helsinki, Finland

Secondments (6 months/24 months). Johan Kotze and Heikki Setälä, University of Helinski, Finland (co supervisors). Dr Kotze and Prof. Setälä are worldwide experts in urban ecology. Along with their scientific expertise complementary to French supervisors, the secondment will add a positive value to the project and will expand the professional network of the candidate.
