Land degradation in general and soil erosion in particular is a serious threat to landscapes compromising their overall health. For planning and targeting, spatially distributed information about the magnitude of the problem and its drivers are necessary.

Erosion is a complex processes governed by diverse drivers which operate at different scales and interact at different levels, making its predication difficult. Due to scarcity of data, accurate estimation of soil loss and modelling its spatial variability at landscape and regional scales is difficult in developing regions.

Physical-based models require detailed understanding of hydrological and modelling processes thus less applicable in data scarce regions.
