Rainwater Harvesting Structures in Rajasthan

Rainwater harvesting is a traditional and widely practiced technique in the arid regions of Rajasthan, India. It is an important source of water for both domestic and agricultural purposes in the region. The local name for rainwater harvesting structures in Rajasthan is "Kund" and "Tank".

Kund:
A Kund is a locally constructed rainwater harvesting structure that is commonly found in rural areas of Rajasthan. It is essentially an underground tank or well-like structure that collects and stores rainwater. Kund is typically made by digging a large pit or trench in the ground and lining it with impermeable materials such as clay or concrete to prevent water seepage. The Kund is designed to capture and store rainwater during the monsoon season, which can be used for various purposes throughout the year. The size and depth of the Kund vary depending on the availability of land and the water requirements of the community.

Tank:
A Tank is another type of rainwater harvesting structure commonly used in Rajasthan. It is a large water storage reservoir that is typically built above ground level. Tanks are usually constructed by building embankments or bunds around a natural or artificial depression in the ground to create a storage pond. The bunds are reinforced with stones, bricks, or concrete to prevent leakage and ensure the storage of rainwater. Tanks can have a significant storage capacity and are often used to collect water from multiple catchment areas. They play a crucial role in replenishing groundwater levels and providing water for irrigation, livestock, and other purposes.

Both (1) and (2):
The correct answer to the question is option 'D' - Both (1) and (2), which means that the local name for rainwater harvesting structures in Rajasthan is both Kund and Tank. These structures are integral to the water management system in the region and have been used for centuries to cope with the scarcity of water in the arid landscape of Rajasthan. The combination of Kund and Tank allows for efficient collection, storage, and utilization of rainwater, ensuring the sustainability of water resources in the region.
