within irrigated area and their dry surroundings in Senegal and Mali.

     - The group target is an assemblage of rodent species, some of which being pests
       for human health and agriculture. 
     - The context is that of changing environmental and agricultural conditions in Sahel
       as well as structuring processes of the species assemblages.
     - The approach is based on field sampling and monitoring.

The report attached synthesises the research program and the preliminary field data
