What does terrace farming help to prevent?

Terrace farming helps to prevent several problems related to agriculture, especially on sloping land:

1. Soil Erosion: This is the most significant benefit. Terraces act as barriers, slowing down the flow of rainwater and reducing the force with which it washes away topsoil.

2. Water Runoff: Terraces help to capture rainwater and allow it to infiltrate the soil rather than flowing downhill and potentially causing floods or landslides.

3. Soil Degradation: By reducing erosion and improving water retention, terrace farming contributes to healthier soil with better fertility and structure.

4. Landslides: Terraces provide stability on slopes, reducing the risk of landslides, especially during heavy rainfall.

5. Siltation: Terraces prevent the erosion of soil from higher elevations and its deposition into rivers and reservoirs, thus reducing siltation and maintaining their capacity.

6. Crop Damage: The reduced runoff and soil erosion protect crops from being washed away or damaged by water flow.

Overall, terrace farming is a sustainable and environmentally-friendly agricultural practice that helps to conserve soil resources and protect the surrounding environment.
