Contour bunding is a method of soil conservation used in

  1. desert margins, liable to strong wind action
  2. low flat plains, close to stream courses, liable to flooding
  3. scrublands, liable to spread of weed growth
  4. None of the above

Answer

None of the above

  • (a) Contour bunding is done across the slope to check runoff and soil erosion by water, mainly on sloping cultivated land. It is not a method for desert margins facing wind erosion. Verdict: Incorrect.
  • (b) Low flat flood-prone plains near streams need embankments/drainage/flood-control measures, not contour bunding, which requires a noticeable slope. Verdict: Incorrect.
  • (c) Contour bunding is a soil and water conservation measure, not a method to control weed spread in scrublands. Verdict: Incorrect.
  • Since (a), (b), and (c) are all incorrect, the correct answer is (d) None of the above.
