Contour bunding is a method of soil conservation used in

Smart Elimination

We associate countours with Hills/Mountains. As, options (a), (b) and (c) dosnt point out any relevance to Mountains, we go with none of the above (option (d))

Potential Trap

Contour bunding is for slopes/hilly areas. None of the options (Desert margins, Low flat plains, Scrublands) perfectly describe 'Hilly/Sloping agricultural land'.

Answer Key & Explanation

Answer: D

The correct answer is Option D.

Explanation:

  • Contour Bunding: Involves constructing embankments along contours (lines of equal elevation) to arrest water flow and soil erosion.
  • Ideal Location: It is primarily used in hilly areas or sloping lands with scanty to moderate rainfall to retain moisture and prevent runoff.
  • Option Analysis:
    • (a) Desert margins (strong wind): Requires Wind Breaks/Shelter belts.
    • (b) Low flat plains (flooding): Bunding here is for flood control, not 'contour bunding' for soil conservation in the traditional sense.
    • (c) Scrublands (weed): Irrelevant.
  • Since the specific context of 'sloping agricultural land' is missing and other options refer to specific mismatching conditions, 'None of the above' is the official answer.

Value Addition

  • Terrace Farming: Used on steep slopes.
  • Shelter Belts: Used in coastal/dry regions to block wind.
