(i) Bush fallowing may leave land unprotected against the agents resulting in wind erosion.

(ii) Over cropping leads to soil exhaustion thus making the soil vulnerable to erosion.

(iii) Cultivation on river banks/steep slopes increases soil erosion processes.

(iv) Deforestation/cutting down of trees exposes the soil to agents of erosion.

(v) Continuous ploughing weakens the soil structure making it easy for agents of erosion to carry it away.

(vi) Ploughing across the contour/up and down the slope creates channels which encourages easy removal of soil by running water.

(vii) Overstocking leads to trampling on the top soil by animals thereby loosening the particles and making them easy to carry away.

(viii) Overgrazing leads to removal of vegetation cover thus exposing soil to agents of erosion.

(ix) Continuous burning without replenishing soil nutrients deprives the soil of the fertility which binds the particles together. This makes soils prone to erosion.

(x) Mining/quarrying/road construction loosens the soils making them easily eroded.
