Abstract

The improved erosion hazard methodology presented in Part I of this paper was applied to Lesotho. Values for variables describing the contribution of the major factors in erosion were abstracted from existing topographic, soil and rainfall maps, and from climatic data and crop yield statistics. Using the SLEMSA framework as a model for combining the influence of the variables, the information was organized on a 14 x 14km grid to give an erosion hazard map of Lesotho. Slope and rainfall are the dominant factors, and they largely explain the variation in "Erosion Hazard Units' from 64 in the southern lowlands to 3230 in the north-eastern mountains
