The lab is structured into 4 teams (3 scientific teams and 1 engineering team), 3 technical units supporting research activities and 2 cross-cutting workshops that ensure transversality between teams or between teams and technical units.

The three scientific teams are organised according to the three main functions of the landscape under study :

• Soil and water contaminants
• Soil resource under global changes
• Ecohydrology of agrosystems

The mission of the "OpenFLUID and engineering for landscape modelling" engineering team is to develop, enhance and disseminate the landscape modelling platform OpenFLUID and provide the numerical computational skills required for the intern development of mechanistic models.

Three technical units are supporting the laboratory's scientific activities for administrative, instrumental/experimental and information systems tasks.

Two transversal workshops complete the lab organisation:

• The "Agroecology of Landscapes" workshop has a transversal function organizing the confrontation of the main functions studied by each of the teams. One of the priorities of this workshop is to revisit the 5-year strategy for the production of models, their coupling and their capitalisation in connection (non-exclusive) with the OpenFLUID platform.
• The "Innovative experiments and observations" workshop is transversal to scientific teams and technical units, telying also the lab with other innovative technical structures outside the lab (FabLabs, dedicated networks). It aims at organizing the internal innovation in metrology, on observation systems, on experimental protocol. A first use of the workshop products may be the OMERE Observatory.

Finally, the Environmental Research Observatory (ORE OMERE), with two locations in the North and South of the Mediterranean (France-Tunisia), is not a structure specific to LISAH, but is an important element in the structuring of the lab's activities (2 ORE co-leaders, 2 site co-organizers).
