Give the importance of khadin system
Answers
Answer:
Explanation:
→ A traditional rainwater harvesting system for agriculture called KHADIN which is used in Rajasthan.
The main feature of khadin system of rainwater harvesting is a very long (100 m to 300 m long ) earthen embankment called 'bund' built across the lower edge of the sloping farmland (see the attached pic ).
The rainwater from catchment area flows down the slopes and stopped by the bund to form a reservoir.
The excess water flows across the bund through sluiceways (or pathways) provided for this purpose and goes into shallow wells dug behind the bund.
The rainwater which collects in the reservoir formed by the bund, and the well, seeps slowly into the land (or ground).
This water - saturated land is subsequently used for growing crops.
