**5. Conclusion**

Associating multi-criteria analysis with GIS offers possibilities for risk management that integrates, in a systemic vision, a set of parameters relating to its comprehension. These techniques have been applied to the Menoua watershed for modeling soil sensitivity to erosion. The final map obtained is intended to guide actors on the sustainable management of potential erodible zones. It highlights five categories of sites: very low, low, moderate, high, and very high sensitivity to erosion. There are two sites whose sensitivity to soil erosion is high. The first to the north, is around the summit of Mount Bamboutos, where a combination of ferralitic soils, agricultural activities, and steep slopes are decisive factors of erosion. The second in the south, is limited to the major tectonic zones of the area (foréké escarpment). It has a high drainage density in areas whose outcropping lithology corresponds to ferralitic soil formations on gneiss that stand out on the sloping ground. As for areas with low erosive sensitivity, they are found in isolated points throughout the basin. The study reveals that the level of very strong and strong erosion sensitivity accounts for 8.82%. The basin is therefore a geographical area at risk of erosion. In order to optimize the reliability of the map produced, a field mission made it possible to validate the sites prone to erosion. Based on these findings, it is recommended that erosion sensitivity should be taken into account when carrying out agricultural development projects. Adopting no-tillage farming technique and the agroforestry can reduce sensitivity to erosion and ensure sustainable management of mountains.
