Laboratory for the study of Soil-Agrosystem-Hydrosystem interactions

LISAH researches deals with hydrology, contaminants transfer and erosion in cultivated landscapes, and on the spatial properties and temporal changes of the landscapes, in order to address following an integrated approach and with a broad view the many challenges relative to water and soils in cultivated landscapes.

The goals of LISAH

  • To develop knowledges on mass (water, erosive) transfers and on the ecodynamics of contaminants (with a focus on pesticides) in soils and cultivated catchments in relation to the organization (in time and space) of both natural (soils, landform) and anthropic (land use, management, agricultural practices) properties.

  • To develop tools allowing the identification and prevention of risks arising from human activities in cultivated landscapes and affecting both hydrological regimes and soil and water resources evolution.

  • To contribute to the definition of new methods for sustainable landscape management

  • To train students in the concepts and tools for the analysis and modelling of spatial organization and hydrology of cultivated landscapes.

Researches focused mainly on the Mediterranean environment, and secondarily on the tropical environments

The laboratory operates in Maghreb countries (Tunisia, Morocco) relying on a network of partners (INAT, INGREF and ENIT in Tunisia; IAV, INRA and ENFI in Morocco).

Secondarily, the lab has developed activities in the tropical areas on the study of the environmental impacts of intensive agriculture on soils and water. In particular it is active in Guadeloupe with partner Institutes or units (INRA, BRGM, CIRAD, IRD).

A laboratory with ca sixty scientists and technicians

LISAH staff comprises 25 researchers and lecturers-researchers and 17 technicians and engineers from INRA, IRD and SupAgro.

Our scientific skills are in hydrology, soil sciences, agronomy, erosion, pollutant transfers and spatialisation methods; our technical skills cover,  hydro-metrology, hydrochemical measurements, soil  physical measurements, in database conception, in geomatics, software engineering and in web site and interface designing.

LISAH is also a host laboratory for students from the North or South undergoing training. Ten to twelve PhD students work in the laboratory, as well as post-doctorate fellows and students during their graduate and post-graduate internships.
