• 40% of Moroccan territory exposed to moderate–severe degradation [2].
• 2 million ha agricultural land degraded by water erosion [3].
• Erosion rates range between 5–20 t/ha/yr, up to 50 t/ha/yr in northern mountains [4, 5].
• Reservoir storage loss: 75 million m³/year (≈ one medium dam/year) [3].
• Current erosion assessment methods lack the precision and accuracy needed to identify sediment sources and capture true sediment dynamics [6, 7, 8].
• A robust, integrated framework is urgently needed to identify erosion hotspots and support effective mitigation
This study aims to enhance soil erosion assessment in Morocco by integrating RUSLE–GIS analysis, advanced remote sensing, isotope techniques, hydrological modeling, and field measurements.
