Question

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

Answer 1

$\huge \mathbb\purple{SOIL \: EROSION}$

• The denudation of soil cover and subsequent washing down is called soil erosion.
• It is caused by deforestation over grazing, mining,etc.,

$\mapsto \large \mathtt\blue{Contour \: Ploughing}$

• It is the process of ploughing along the contour lines to decelerate the flow of water down the slopes.

$\mapsto \large \mathtt\blue{Terrace \: Farming}$

• Steps can be cut out on the slopes making terraces.
• This restricts the erosion.

$\mapsto \large \mathtt\blue{Strip \: Cropping}$

• Large fields can be divided into strips.
• Strips of grass are left to grow between the crops.
• This breaks the force of wind.

$\mapsto \large \mathtt\blue{Shelter \: Belts}$

• Planting rows of trees to create shelter works in a similar way.
• It has contributed to the stabilisation of sand dunes in Western India.
