Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Artificial Recharge Intervention modules at adopted villages: The artificial recharge to
groundwater aims at augmentation of groundwater reservoir by modifying the natural
movement of surface water.

Rainwater harvesting and its recycling /recharging of groundwater: Rainwater harvesting
and recycling through farm ponds and restoration of old water harvesting structures in the
village may be useful in rainfed areas. Percolation tanks and ponds may be tried for recharging
of wells.
Recharge of wells with rainwater: The groundwater is depleted year by year because of dense
bore wells. These open wells may not be yielding enough water to meet the requirements of
farm operation during early monsoon. The percolated water from rainfall requires a few weeks
time to bring the water level up or recharge the wells. Farmers cannot store runoff water
separately in the field itself.
Impacts measurability: The activities implemented in villages include those that provide
benefits in the short as well as long term. Further, some of the impacts will be visible only in
the long term.
Results
Ex-situ rainwater harvesting and efficient utilization: The importance of rainwater
harvesting has increased in recent years due to the increased rainfall variability, heavy rains
and depletion of groundwater levels. Surface-water storage structures can play a vital role in
augmenting groundwater recharge, especially in semiarid and arid regions. Rainwater
harvesting for recharge of wells and recycling through farm ponds, restoration of old rainwater
harvesting structures in rainfed areas, and open/bore wells for recharging groundwater are
taken up for enhancing farm-level water storage in drylands.
Increased well Yield: Water yield/recuperation rate before and after interventions for different
wells indicates that the recharge rate increased by around 22% before interventions, the wells
