Land degradation occurs when the land becomes unstable. Land degradation can display as a loss of vegetative cover, an undesirable change to the soil (eg. salinity), or as soil erosion.
|Land degradation can be considered in 3 categories:|
This is the where soil is scoured and lost from its position in the landscape. More information on these processes, and on occurrence in Victoria is available on the soil erosion pages.
This is the in-place decline in soil quality. More information on the types and their processes is available on the soil degradation pages.
This is where ecosystem vigour is reduced resulting in loss of ecosystem services. More information is available on the ecosystem decline pages.
