Land Degradation Model
The IMAGE 2.4 Land Degradation Model (LDM) comprises a qualitative description of the land degradation process of water erosion.
Classification of water-erosion sensitivityMaximum correspondence with the GLASOD degradation status maps of Oldeman et al. (1991) was achieved by using a classification of water erosion-sensitivity for which about 85% of the grid cells have a calculated erosion risk that corresponds to the GLASOD water erosion status (see table below). This classification can be used as a guide when analysing the water-erosion sensitivity indicator. | Classification of water-erosion sensitivity index | | Water erosion-sensitivity index | Erosion risk | | < 0.15 | no/low | | 0.15 - 0.30 | moderate | | 0.30 - 0.45 | high | | > 0.45 | very high |
