Answer
1. Overgrazing – use controlled grazing or shade trees. 2. Lack of crop residue – leave residues or mulch. 3. Improper plowing – adopt contour plowing, terracing or bunds.

Step-by-step solution

  1. Overgrazing removes protective vegetation, leading to bare soil; prevent with regulated grazing or planting shade trees.
  2. Lack of crop residue exposes soil to wind and rain; prevent by leaving residues or applying mulch.
  3. Improper plowing or absence of contour plowing causes water to flow downhill and erode soil; prevent by contour plowing, terracing or building bunds.
