Type of land degradation

Remedial actions

Sheet erosion

1) Construct soil erosion control structures such as ridges, fanyajuu and terraces on steep slopes.

2) Apply manure/use leguminous plants in the field to replenish the lost nutrients.

3) Plant trees/leguminous trees/agroforestry trees to serve as windbreak in the field especially for the affected area.

Rill erosion

1) Plant grass or encourage restoration of natural vegetation by abandoning human activities on the area.

2) Use contour ridges to harvest and prevent violent flow of water during rains.

Gully erosion

1) Construct gabions.

2) Planting tress e.g. castrol oil trees (Minyonyo) and sisal to help hold the soil.

3) Stop anthropogenic use of land surrounding the gullies to encourage natural vegetation restoration.

Reduction of vegetation cover

1) Plant trees/leguminous trees/agroforestry trees in the affected area.

2) Use of bench terraces.

3) Use of water diversion structures.

Loss of greenish colour

1) Construct water harvesting structures such as ridges, fanyajuu and terraces on steep slopes.

2) Plant trees and use leguminous plants/crops around contours on steep slopes to replenish the lost nutrients.

3) Use of fertilizers such as manure and inorganic fertilizers to replenish the lost nutrients.
