The geological heritage of the Rehamna region (Morocco) is rich and diverse, but is highly exposed to natural and anthropogenic pressures. Despite numerous geosite inventories in Morocco, no specific quantitative study had yet assessed the risk of degradation in this region, which constitutes a major gap in the implementation of a geoconservation strategy. The objective of this work is to fill this gap by proposing a hierarchy of degradation risk for ten representative geosites in Rehamna. The methodology is based on the Analytic Hierarchy Process (AHP), a multi-criteria approach combining seven vulnerability factors: anthropogenic activity, uncontrolled tourism, proximity to roads, lack of protection, lithology, natural erosion, and climate change. The relative weights of the criteria were established using a pairwise comparison matrix (CR = 0.044), and each geosite was evaluated using field scores, which were then converted into weighted scores. The numerical results show that three geosites—the Sidi Bou Othmane pegmatites (3.48/5), the Paradoxides schists (3.31/5) and the Kettara pyrrhotite (3.29/5)—present a high to moderate-high risk, while the Sebt Brikiine granite (1.77/5) and the Kef El Mounib conglomerates (1.97/5) appear to be low vulnerability. The practical value of this research lies in the development of a decision-making tool for geological heritage managers, enabling them to define conservation priorities and integrate geosites into land-use planning. The originality of the study lies in the first-time application of the AHP method to the Rehamna, accompanied by innovative graphical visualizations (proportional circles and comparative diagrams). The limitations of this work concern the partially subjective nature of the weighting of criteria and the lack of quantitative data on tourist numbers. Nevertheless, the approach can be extended to other regions of Morocco and enriched by the integration of GIS tools and temporal monitoring, thus contributing to the development of a national geoconservation strategy.
