Question

In Shekhawati region and Haryana __________ is the source of rainwater collection.
A) Beri
B) Nadi
C) Baori
D) Johad

Answer 1

Hint: Archaeological evidence exhibits that the strategy of water preservation is deeply grounded in the science of historical India. Excavations demonstrate that the towns of the Indus Valley Civilisation had outstanding networks of water harvesting and drainage.
The accommodation of Dholavira, laid out on a slope between two stormwater tunnels, is an extraordinary illustration of water engineering. Chanakya’s Arthashashtra refers to irrigation using water collecting systems.

Complete answer:
Johads, one of the oldest methods used to protect and replenish groundwater, are tiny earthen inspection dams that capture and stock rainwater. Designed in a region with generally high elevation on three walls, a warehouse pit is prepared by digging up the area, and excavated mud is used to construct a barrier on the fourth side. Occasionally, diverse johads are interconnected by deep passage, with a solo vent into a brook or stream close by.
It’s crucial to remark that water johads are place-specific technologies and cannot inevitably be duplicated to other geographical settings or climates. They need steady sloping land—where every johad can sustain water into another downstream—and a rainy season, where rains can crowd up the reservoirs during the arid months.

Hence, the correct answer is option (D).

Note: The Government of Haryana is modernizing several johads of Gurugram. In 2017, Chief Minister of Haryana Manohar Lal Khattar declared that the Government of Haryana will form the Haryana State Waterbody Management Board. The purpose is to revitalise and govern 14,000 seas in Haryana. It may be done by excavating the mud out each year.
