This is an ideal setting of the Khadin system and A = Catchment area; B = Saline area & C = Shallow dugwell / biodiversity which faces large destruction

(1)

This is an ideal setting of the Shallow dugwell system and A = Catchment area; B = Saline area and C = Khadin / local people whose basic needs can no longer be met from such forests

(2)

This is an ideal setting of Catchment area and A = Khadin, B = Saline area and C = Shallow dugwell / industries

(3)

This is showing Saline area and A = Catchment area; B = Khadin and C = Shallow dugwell / forest department

Official answer

This is an ideal setting of the Khadin system and A = Catchment area; B = Saline area & C = Shallow dugwell / biodiversity which faces large destruction

Hint

$The diagram shows a traditional water harvesting system, which is the Khadin system. The Khadin system consists of a catchment area (A), a saline area (B), and a shallow dugwell (C).$

Quick oral answer

$The Khadin system is a traditional water harvesting system that collects and stores rainwater for irrigation and other purposes. It consists of a catchment area, a saline area, and a shallow dugwell. The catchment area collects rainwater, which flows into the saline area, where the water is stored. The shallow dugwell is used to extract water from the saline area for irrigation and other purposes.$

Common mistakes

1. $Confusing the Khadin system with other water harvesting systems$
2. $Not understanding the components of the Khadin system$

Analysis and explanation

The Khadin system is a traditional water harvesting system that collects and stores rainwater for irrigation and other purposes. It consists of a catchment area, a saline area, and a shallow dugwell. The catchment area collects rainwater, which flows into the saline area, where the water is stored. The shallow dugwell is used to extract water from the saline area for irrigation and other purposes.

Interesting facts

$The Khadin system is an ancient water harvesting system that has been used for centuries in India.$

$The Khadin system is still used today in many parts of India, particularly in rural areas where access to modern irrigation systems is limited.$
