Scientists work with farmers to prevent loss of fertile soil

Scientists are working with farmers to help them reclaim sloping land ruined by heavy rainfall, through terracing and planting extra crops that hold the soil in place in a drive they say repairs soil fertility and increases yields.

Terracing is common in Kenya, but only when coupled with the planting of the right trees and shrubs does it raise yields per hectare by between 15 to 40 per cent.
