Answer 2

Answer:

Palar pani is not a rainwater harvesting technique in Rajasthan.

Explanation:

• Palar Pani is the water that is directly received from rain which is collected on the surface.
• Rajasthan is a dry state and in the arid and semi-arid regions, rainwater is the purest form of water since its rainfall is less than 25cm.
• Palar Pani is conserved for future use, especially during summer days when all reservoirs are dry due to scarcity of water.
• This is the purest form of water, which is conserved underground.

Note

• All the other options mentioned above are water harvesting systems in Rajasthan.
• A Khadin, which is also known as Dhora, is constructed to harvest surface runoff water for agriculture.
• Johads are earthern check dams that harvest rainwater, improving percolation and ground water recharge.
• Tanaka is a traditional rain water harvesting technique for a family or a group of small families.
