The erosion mapping showed that over 50% of the island had considerable to extremely severe erosion (Arnalds et al. The classification of land based on erosion give good estimates on conditions of land, and can also be an indication of degradation (Figure 4.3). This is however not fully adequate for degradation classification as land classified as 1 and 2 could be degraded although well vegetated, and some land is eroded due to natural reasons.
