The combat against land degradation in Lesotho has been in existence since the arrival of the missionaries but failed due to lack of scientific evidence on the cause, extent and severity of the degraded watersheds to help plan sustainable management strategies to mitigate land degradation. Field investigation was conducted using LADA Soil Assessment Methodologies to assess the physical properties of the Bolahla- Mphosong catchment to provide a first-hand scientific data on the state and causes of land degradation for decision support making at the different levels of economic planning. The field assessment indicated that the soil quality status of the catchment was moderate but high bulk density and high slope gradients were the main causes of land degradation in the Bolahla-Mphosong catchment. Sustainable management practice such as Conservation Agriculture (CA), organic mulching, contour ridging and stripe cropping, avoiding overgrazing and farming on marginal lands should be encouraged among the land users to help mitigate land degradation in the catchment.
