Identify a water-harvesting system found in Jaisalmer.

Question

Accepted Answer

Step-by-step explanation:

1. Identify the systems:
   - $(1)$ Guls: traditional mountain water channels (Kashmir/Himachal) — not typical of Jaisalmer.
   - $(2)$ Johads: small earthen check dams used in parts of Haryana and eastern Rajasthan.
   - $(3)$ Khadins: large earthen bunds across slopes in western Rajasthan (Jaisalmer/Barmer) to trap runoff and create cultivable land.
   - $(4)$ Kuls: irrigation channels (Himachal/Kangra region), not Jaisalmer.

2. Reasoning: The Khadin is the characteristic water-harvesting and runoff-farming system of Jaisalmer and other parts of western Rajasthan. It works by building a long earthen bund to collect surface runoff, allowing moisture to accumulate for cultivation.

3. Conclusion: The correct choice is $(3)$ Khadins (option c).
