-Overstocking reduces vegetation cover exposing soil to agents of erosions

- Ploughing up / down a slope provides channels for surface run off. These are enlarged to become gullies

- Deforestation / cleaning of vegetation cover exposes soil to agents to erosion.

- Mining/ Quarry/ road construction loosens / exposes the soil making of it susceptible to erosion.

- Human settlement and cultivation on steep slope / rivers frontage increases soil erosion processes.

- Continues cultivation without replenishment of soil fertility leads to soil exhaustion making the soil vulnerable to erosion.

- Shifting cultivation / bush fallowing leaves land unprotected against erosion.

-Overstocking – farmers to reduce the number of livestock

- Deforestation – Plant more trees / reafforestations

- Ploughing on steep slopes – contour ploughing

- Monoculure – diversification of crops
