iv) Gabions; they are built across a valley to trap soil and reduce speed of water.

v) Dams/reservoirs, built across a valley to hold/store water/reduce speed of water.

vi) Contour farming; carried along the contour to reduce speed of runoff.

vii) Mulching; reduce speed of run-off; avoid splash erosion; reduce evaporation and increase the water
holding capacity of the soil.

viii) Afforestation/forestation/agroforestry; Trees protect the soil from splash erosion by reducing the force with which rain falls on the ground; act as windbreaks/roots bind soil particles.

ix) Use of grass strips/filter – helps to slow the speed of water run-off and trap eroded soil.
