Natural and Man-made Hydrosystems Ecology Laboratory (LEHNA)

Date of the last update : 22/03/2023


The Natural and Man-made Hydrosystems Ecology Laboratory (LEHNA) is a mixed research team (UMR 5023) supervised by 3 institutions: the CNRS, Lyon 1 University and ENTPE. It is under a contract with the INRA and is based at two sites: Villeurbanne and Vaulx-en-Velin.

The Impact of Pollutants on Ecosystems team is based at the ENTPE site.

The team's research involves assessing the environmental impact of transport infrastructure and urban development.

The aim of the research conducted by LEHNA’s team is:

  • to enable the design and development of tools and parameters for characterizing the functional state of ecosystems,
  • to assess the disruptions and ecotoxicological risks incurred by living communities,
  • to produce explanatory and predictive models of how the environments in question function.

The aim of this research is therefore to provide reliable evidence for decision-making and help manage anthropic environments.
