Question

What is the difference between land degradation and soil degradation?

Answer 1

Land degradation is a process in which value of land is affected by human activities. Land degradation is a broader definition which includes degradation due to pollution, wind erosion etc. Soil erosion refers to the removal of top soil which is considered to be most fertile. Soil erosion is a part of land degradation.

Answer 2

Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land.[1] It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.[2] Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires.

Soil retrogression and degradation are two regressive evolution processes associated with the loss of equilibrium of a stable soil. Retrogression is primarily due to soil erosion and corresponds to a phenomenon where succession reverts the land to its natural physical state.
