| Summary: | The objective of this study is to identify the most suitable areas for the implementation of a solid waste landfill in the province of Tangier-Assilah using geographic information systems (GIS). This approach aims to minimize pollution and its negative impacts on the environment and society. In this study, eight environmental, social and economic factors were considered, including residential areas, distance from roads, distance to water bodies, distance to forests, elevation, slope, aspect and parks. To determine the importance of each criterion, the Analytic Hierarchy Process (AHP) was used, based on a pairwise comparison matrix. In addition, a map was produced to indicate the most suitable and unsuitable areas for the solid waste landfill facility. This model can be used to help decision makers make informed decisions and develop effective planning strategies for selecting the most appropriate sites for the landfill.
