Answer:
As a robust climate adaptation strategy for drought-prone areas in Sikkim, Dhara Vikas (meaning, springshed development), an innovative programme was adopted in 2008 to revive and maintain drying springs, which is helping to alleviate the problem of rural water scarcity by reducing surface run-off of rainwater and ...
Traditinal Methods of Water Storage in Sikkim are :~
1. Jhalara
Jhalaras are typically rectangular-shaped stepwells that have tiered steps on three or four sides. These stepwells collect the subterranean seepage of an upstream reservoir or a lake.
2. Bawari
These are unique stepwells that were once a part of the ancient networks of water storage in the cities of Rajasthan. Water is diverted to man-made tanks through canals. The water would then percolate into the ground, raising the water table and recharging a deep and intricate network of aquifers. To minimize water loss through evaporation, a series of layered steps were built around the reservoirs to narrow and deepen the wells.
3.Johads
Johads, one of the oldest systems used to conserve and recharge groundwater, are small earthen check dams that capture and store rainwater. Constructed in an area with naturally high elevation on three sides, a storage pit is made by excavating the area, and excavated soil is used to create a wall on the fourth side.
