Answer Text:
Methods of Land Rehabilitation
Afforestation and Reafforestation as a method of Land Rehabilitation.
- Improve the productivity of land in the following ways:
a) Controls soil erosion by:
- Acting as wind breakers
- Leaves reduce impact of raindrops on the soil
- Roots hold/bind the soil particles together.
b) Vegetation reduces runoff and increases the rate of
infiltration of rain water ensuring there is a complete water cycle.
c) Decayed vegetation provides humus which restores soil fertility.
d) Roots help moisture to percolate deeply into the ground.
e) Modifies the climate of an area by moisture being released to the atmosphere causing higher rainfall and lowering the temperature.
