Question:

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

Answer:

The following steps can be taken to control soil erosion in the hilly areas:
a) Ploughing along the contour lines can decelerate the flow of water down the slopes. This is called contour ploughing.
b) Steps can be cut out on the slopes making terraces. Terrace Cultivation restricts erosion.
c) Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind. This method is known as strip cropping.
d) Planting lines of trees to create shelter also works in a similar way. These shelterbelts have contributed significantly to the stabilisation of sand dunes and in stabilising the desert in western India.
