Our research in soil science is part of a broader context, where soil health plays a central role in current environmental challenges. Soil is well-known for providing ecosystem services that are essential to human well-being: food supply, water and air regulation, support for life, etc.
Soil damage such as compaction, erosion, loss of organic matter and biodiversity therefore has a direct impact on the functioning of terrestrial ecosystems.
With a view to sustainable management, our research focuses on studying the role of soil organisms and understanding their interactions and implications for the maintenance and resilience of ecosystems.
Our research contributes to the development of sustainable management practices, aimed at protecting soils while meeting the growing needs for food security and biodiversity.
The Pedofauna group focuses on soil biology, with a particular interest in earthworms and their crucial role in pedogenesis processes.
Our research aims to understand how soil organisms may influence:
Our studies focus more specifically on alluvial, agricultural and urban environments, combining fundamental and applied sciences.

Discover how the soils in Lausanne’s parks can help combat heat islands! In this new article, find out about the initial results of the URBA-SOIL project, which is dedicated to studying anthroposols, these often modified and little-known urban soils.
Through in situ measurements, 3D tomography analyses, and interdisciplinary collaborations, the team is exploring how these soils absorb and retain water, and how their management can help cool the city. The project paves the way for concrete recommendations to improve soil permeability and de-seal urban spaces.
A fascinating dive into the heart of urban soils—between science, climate, and development issues.
