Answer 1

Correct Answer - Option 3 : Nadis

The correct answer is Nadis.

• Nadis means a dug-out village pond or tank.
• Its catchment area is large.
• Nadis receive their water supply from rainfall.
• The water stored in Nadis acts as a source of groundwater recharge through seepage and deep percolation.
• The water is used for drinking and household purposes.
• This water harvesting system is more prevalent in western Rajasthan.  

• Ahar Pynes is a traditional floodwater harvesting system indigenous to South Bihar.
  • Ahars are reservoirs with embankments on three sides that are built at the end of diversion channels like pynes.
  • Pynes are artificial rivulets led off from rivers to collect water in the ahars for irrigation in the dry months. 
  • Paddy cultivation in this relatively low rainfall area depends mostly on ahar pynes. 
• Bundhis are the traditional water harvesting system found in Madhya Pradesh.
• Tals are the traditional water harvesting system found in Maharashtra.
