Résumé :	The Loukkos large perimeter covers an area of 256 000 ha, 147 300 ha of which are useful agricultural areas and 42 000 ha of which are currently irrigated. In this study we analysed the impact of agricultural managements on wetlands in Loukkos (Morocco), using the mapping approach of the evolution in irrigated sectors of the Loukkos perimeter. As a result, 34% of wetlands, including two Ramsar Sites were negatively impacted. The conversion of natural ecosystems to agricultural fields, the overuse of water in irrigation and the urbanization are the most factors that threaten the wetlands’ surfaces. Finally, the mapping of the evolution of the irrigated sectors of the Loukkos perimeter made it possible to assess the current situation and the criticality degrees of the impacts with the estimation of the impacted areas. This mapping approach will facilitate the initi- ation for a more specific approach where the most sensitive and affected areas will be satisfied.
