Soil conservation

• stopping rivers flooding. building small dams in gullies to slow down water run-off. digging channels across farm slopes to divert water. protecting areas likely to be eroded.

Answer 2

Afforestation

One of the best ways to conserve soil is to increase the area under forests. Undiscriminating trees cutting should be stopped and efforts should be made to plant trees in new areas.

Checking overgrazing

Grazing land is very important but overgrazing foresta and grasslands by animals especially by herds, flock of sheeps and goats should be properly checked.

Constructing Dams

Soil erosion which happens maximum times by river floods can be avoided by constructing dams across the rivers. Water speed can be checked and this considerably saves soil from erosion.

Since the 1940s, many methods have been used to save the soil and prevent erosion, including:

• planting trees
• using new farming methods
• stopping rivers flooding
• building small dams in gullies to slow down water run-off
• digging channels across farm slopes to divert water
• protecting areas likely to be eroded.
