Groundwater exploitation has grown at a rapid rate and has challenged human capability to sustain the resource, and where the climate is drying the challenge has intensified. Despite various negative consequences of natural and anthropogenic changes, groundwater still has the potential to mitigate impacts of climate change if properly managed, and is probably the most resilient water resource.

A capacity building program is designed by IIT Roorkee, NIH Roorkee, KU Japan, and PNU South Korea under the project entitled “Site suitability mapping for Managed Aquifer Recharge (MAR) under varying climatic conditions using remote sensing and machine learning based hydrological modelling tools” funded by Asia-Pacific Network (APN) for Global Change Research under scientific capacity development programme (CAPaBLE).

• Underground rock formations or sedimentary deposits that are permeable enough to store water are known as aquifers. Most aquifers are naturally recharged by rainfall or other surface water that infiltrates into the soil. Aquifers, on the other hand, will be depleted over time in regions where groundwater consumption surpasses natural recharge rates.
• Managed aquifer recharge (MAR), often known as water banking, is a type of water management that involves employing either surface or subterranean recharge techniques to recharge an aquifer. During dry years, when surface water sources may be scarce, the stored water might be used.
• The planned recharging of water into aquifers for eventual recovery or environmental benefit is known as managed aquifer recharge (MAR). Injection wells, infiltration basins, and galleries are frequently used to collect rain, stormwater runoff, reclaimed water, mains water, and water from other aquifers, which is subsequently recovered for a number of uses.
