Laboratory for the study of Interactions between Soils, Agrosystems, Hydrosystems (LISAH)

Director: Jérôme Molenat

Research area
The Unit ‘Laboratory for the study of Interactions between Soils, Agrosystems, Hydrosystems' groups both researchers and academic staff from the National Institute for Agricultural Research (INRA), the Institute of Research for Development (IRD) and the School of Agronomy of Montpellier (Supagro).
Its central research theme is the study of the spatial organisation and hydrology of agricultural landscapes both in developed and developing countries. Specific objectives are to:
  • increase basic understanding about erosion, water and pollutant transport processes in soils and farmed catchments as a function of their spatial and temporal heterogeneities, both natural and land use related
  • develop new methods and tools for detecting and preventing threats to soil and water resources
  • design sustainable management strategies for rural landscapes
  • educate students on the concepts and tools for analysing and modelling the spatial organisation of farmed landscapes and their hydrological behaviour.
The unit has three main research programs:
  • Studying and modelling transport mechanisms from field to catchment scales
  • Analysing and modelling the spatial organization and evolution of the functional properties of farmed landscapes according to their hydrological behaviour
  • Developing distributed eco-hydrological modelling approaches
The LISAH manages a long term environmental observatory, called OMERE (Observatoire Méditerranéen de l'Environnement Rural et de l'Eau), which aims at studying the impact of human activities on runoff, erosion and subsequent changes in water quality. This observatory consists of two experimental catchments located in South France near Montpellier and in Tunisia in the Cap Bon region. The two sites represent two different stages in the evolution of Mediterranean farmed landscapes.

Research highlights
  • Development of distributed hydrological modeling in farmed catchments
  • Water contamination processes by pesticides at the catchment scale in semi-arid environments
  • Evaluation of water harvesting techniques at field and catchment scales
  • Impact of global change on the soil vulnerability to soil erosion
  • Development of digital mapping of soils and of anthropogenic landscape features
