Megha's village was facing the problem of soil erosion. Choose the measures from the given options which you will suggest the people living in that village to prevent the soil erosion?
The correct options are
A Afforestation
D Making farmland boundaries.
The washing away of the top layer of the soil by wind or water is known as soil erosion. Heavy rainfall, overgrazing, deforestation, etc are the major factors which cause soil erosion. The methods to prevent soil erosion are:
(i) Afforestation- Planting of more trees.
(ii) Making farmland boundaries- This retains rainwater hence preventing washing away of the soil.
(iii) No overgrazing- Overgrazing by cattle can make the land barren. So this should be avoided to prevent soil erosion.
(iv) Strip farming- Strips or bands are made on the slope of the hills hence preventing washing away of sand.
More usage of pesticides can cause soil pollution, so, this is not a good measure to prevent soil erosion.
