4. CAUSES :
 Land clearance,such as deforestation and clear
cutting
 Agricultural depletion of soil nutrients through poor
farming practices
 Livestock including overgrazing and overdrafting
 Inappropriate irrigation,mono culture and over
drafting
 Soil contamination and mining activities.
 Dumping of non-biodegradable trash, such
as plastics

5. EFFECTS:
Soil erosion is one of the most
destructive phenomena of land
degradation.
Surface runoff and floods.
Desertification.
Loss of Nutrients and land productivity.
Loss of fodder,decline in production of
timber.

6. STATISTICAL VIEW

7. PREVENTIVE MEASURES:
 Proper management of waste lands.
 Control of mining activities.
 Proper discharge and disposal of industrial
wastes.
 Using natural fertilizers.
 Afforestation and proper management of
gazing can help to some extent.
 Stabilisation of sand dunes by growing
thorny bushes.
