What traditional water harvesting system is used in the semi-arid and arid regions of Rajasthan?

Correct option is A

The correct answer is (A) Rooftop harvesting.

Explanation:
In the semi-arid and arid regions of Rajasthan, rooftop rainwater harvesting is a traditional and widely used system. This method involves collecting rainwater from rooftops and storing it in tanks or cisterns for future use. The collected water is primarily used for drinking, irrigation, and domestic purposes. This system has been employed in Rajasthan due to the region's frequent water scarcity and low rainfall.

Information Booster:

• Rooftop Harvesting: In this system, rainwater collected from rooftops is directed through gutters and stored in tanks or pits. This method is highly effective in arid and semi-arid areas like Rajasthan, where groundwater is often scarce.

• Rajasthan has implemented traditional water conservation systems, like Johads and Pats, in conjunction with rooftop harvesting, to combat water scarcity in the region.

• The State Government of Rajasthan has promoted rainwater harvesting as part of water conservation efforts, encouraging people to use this method to meet their daily water requirements.

• Rooftop harvesting also helps to reduce dependence on external water sources and ensures self-sufficiency in water supply during dry periods.

Additional Knowledge:

• Guls: A traditional water harvesting method in Kashmir, where water is stored in small ponds or channels.

• Bamboo pipes: Used in northeastern India for water transportation, but not typically used in Rajasthan.

• Tankas: Underground storage tanks used for storing water in Rajasthan and Gujarat, though rooftop harvesting is more common for collecting water.
