How can soil erosion be prevented?

Soil erosion can be prevented by adopting scientific methods to reduce the washing away of the topsoil by wind or water.

Methods of Prevention

• Afforestation: Planting trees to bind the soil with roots.
• Contour ploughing: Ploughing along the slope lines to reduce runoff.
• Terrace farming: Creating steps on hills to slow water flow.
• Windbreaks: Planting trees in rows to block strong winds.
• Cover crops: Growing grass or legumes to protect bare soil.

Human Role

• Avoid deforestation and overgrazing.
• Encourage sustainable farming and replant vegetation after mining or construction.

Importance

Preventing soil erosion protects fertility, prevents floods, and ensures long-term agricultural productivity.
