Question

What do you mean by land degradation?

Answer 1

Land Degradation

Land degradation is the process by which the quality and productivity of land decline, making it less suitable for agriculture, forestry, or habitation. It involves the deterioration of the physical, chemical, and biological properties of soil and the loss of its natural vegetation. This decline is caused by a combination of natural processes and, more significantly, unsustainable human activities.

Key Causes of Land Degradation:

• Soil Erosion: Removal of the fertile topsoil by wind and water.
• Deforestation: Clearing of forests for agriculture or urbanization.
• Overgrazing: Excessive grazing by livestock, which removes vegetation cover.
• Improper Agricultural Practices: Such as excessive use of chemical fertilizers and pesticides.
• Salinization and Waterlogging: Caused by poor irrigation management.

Land degradation reduces agricultural output, threatens food security, and harms biodiversity.
