Answer:
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.
This is considered to be an important topic of the 21st century due to the implications land degradation has upon agronomic productivity, the environment, and its effects on food security.[3] It is estimated that up to 40% of the world's agricultural land is seriously degraded.
CAUSES:-
Land degradation is a global problem largely related to agricultural use. Causes include:
Land clearance, such as clearcutting and deforestation
Agricultural depletion of soil nutrients through poor farming practices
Livestock including overgrazing and overdrafting
Inappropriate irrigation[7] and overdrafting
Urban sprawl and commercial development
Vehicle off-roading
Quarrying of stone, sand, ore and minerals
