Description This paper examines possible management pathways to address soil erosion issues due to
improper land management and landform patterns. Therefore, a landscape management and
planning tool (LAMPT), a spatially explicit model based on the Revised Universal Soil Loss
Equation (RUSLE) adjusted for the sediment delivery ratio (SDR) was used to model the historical
soil loss and evaluate the efficiency of some land management and conservation strategies.
Different database and field characterization were used to calibrate the model for the Mo river
basin and validate the model outputs at the landscape level. In addition, a participatory rural
appraisal approach was used to validate the simulated spatial patterns of soil erosion at the
landscape level. The results indicated that the simulated net soil loss (NSL) for the Mo basin was
higher than the tolerable limits for the Tropics. The local appraisal of soil loss was in line with the
simulated outputs even though quantification was not accounted for when dealing with rural
illiterate people. Simulated historical NSLs were approximately 26, 23, 27, and 44 Mg ha-1y-1,
for 1972, 1987, 2000, and 2014, respectively. Steep slopes (≥ 15 ᴼ), poorly covered lands, and
riversides (distances ≤ 100 m) are critical areas of sediment sources. Measures, such as
controlling erosion hotspots through land protective measures, could help reduce the NSL up to 70%, closer to the tolerable limits for the tropics. The model implementation in the basin showed
insights in identifying soil erosion-prone areas and targeting soil conservation planning and
landscape restoration measures.
