মেইনস
GS-I/GS-III (Karnataka water resources): Tanks, once irrigation and drinking-water sources, now function largely as groundwater-recharge structures in a drought-prone State. Policy responses include tank rejuvenation, protection from encroachment and linking of recharge with watershed schemes and Atal Bhujal Yojana. The way forward lies in community management of tanks, desilting, restoration of feeder channels and groundwater regulation.
