There is a close relation between the occurrence of soil conservation measures and distribution of land use in the Gina River catchment. Soil conservation measures were practiced particularly in the areas with a slope inclination of 9-18 % used for agriculture (see figure). With increasing inclination of slope the occurrence of soil conservation measures decreases but the occurrence of soil erosion damages increases. This led to the assumption that also in these areas soil conservation measures have to be implemented. Alternatively, these areas are less intensive used to prevent soil erosion processes (Beck et al. 2004).

The discussion about the results of the investigation of soil erosion damages in the Gina River catchment is presented next.
