Detailed Solution

Follow these instructions to stop soil erosion in hilly locations.
Afforestation: The best way to save the land is to increase the area under forest. Accidental felling of trees should be prevented, and efforts should be made to plant trees in new areas.
Checking and Reducing Shifting Farming: Checking and reducing shifting farming will reduce soil erosion.
Contour tillage: If the slope of the hill is ploughed perpendicularly following the natural outline of the hill, it breaks the flow of water under the hill. This will prevent soil erosion.
