  abstract = {{S}oil erosion is one of the most critical threats to cultivated land. {Y}et little information is available in {S}ub-{S}aharan {A}frica, especially on the relative contributions of various forms of erosion. {T}herefore, this study's objective was to quantify soil loss by sheet and linear erosion. {T}he study was carried out on the sloping land rangeland of the {P}otshini catchment of {K}wa{Z}ulu-{N}atal, {S}outh {A}frica, with an annual average rainfall of 766 mm. {T}he average sheet erosion computed using a network of 1 m(2) microplots was 7.7 ton ha(-1) y(-1) with standard error of 1.97 ton ha(-1) y(-1) (which corresponded to an ablation rate of between 0.35 to 1.32 mm y(-1)) while linear erosion, mainly the retreat of gully banks, removed 4.8 ton ha(-1) y(-1), i.e., 38.4% of total soil losses. {D}espite removing a lower amount of soil, sheet erosion by depleting fertile, carbon- and nutrient-enriched soil horizons has a great impact on most ecological functions associated with soils.},
