What steps can be taken to control soil erosion in hilly areas?

The methods of soil conservation in hilly regions are :

(i) Plowing along the contour lines decreases the speed of water flow down the slopes.

(ii) terrace cultivation on slopes decreases erosion.

(iii) Strip cropping: large fields are divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind.

(iv) Shelter plantation: here Tree are planted in rows. These shelterbelts have led to the stabilization of sand dunes and in stabilizing the desert in western India.
