๐ Progress in Groundwater Management (2017โ2024)
โ Recharge Increase: Groundwater recharge rose by 15 BCM between 2017 and 2024.
โ Less Extraction: Annual groundwater extraction decreased by 3 BCM in the same period.
โ Safer Groundwater Zones:
- Safe assessment units increased from 62.6% in 2017 to 73.4% in 2024.
- Over-exploited units reduced from 17.24% to 11.13%.
โ Role of Conservation Structures:
- Recharge from tanks, ponds, and water control systems rose from 13.98 BCM in 2017 to 25.34 BCM in 2024โan increase of 11.36 BCM.
๐ Challenges in Groundwater Quality
โ Major Pollutants: Arsenic, fluoride, chloride, uranium, and nitrate pose health risks.
โ Sources of Contamination:
- Industrial discharge, agricultural runoff, and saline intrusion increase Electrical Conductivity (EC).
- Iron contamination impacts water quality, causing potential health issues.
โ Positive Trends in Agriculture:
- 81% of groundwater samples are suitable for irrigation.
- 100% of samples from northeastern states are rated "excellent" for agricultural use.
๐ Key Government Initiatives
โ Jal Shakti Abhiyan (2019): Now in its fifth phase ("Catch the Rain" 2024), this program emphasizes rainwater harvesting and conservation in rural and urban districts.
โ Atal Bhujal Yojana (2020): Participatory groundwater management in 80 water-stressed districts across 7 states.
โ Mission Amrit Sarovar (2022): Aims to create or rejuvenate 75 waterbodies per district for rainwater harvesting.
โ National Aquifer Mapping (NAQUIM): Mapped over 25 lakh sq. km to support groundwater recharge and conservation.
โ Master Plan for Artificial Recharge (2020): Proposes 1.42 crore rainwater harvesting and recharge structures to harness 185 BCM of rainfall.
๐ Achievements in Groundwater Management
โ Improvements in 128 groundwater units were noted between 2023 and 2024, reflecting the success of policy initiatives.
โ Recharge from water bodies like tanks and ponds has consistently increased, demonstrating the effectiveness of local interventions.
๐ The Path Forward
โ Use advanced technologies like AI and GIS to monitor groundwater quality and optimize conservation efforts.
โ Strengthen community involvement through programs like MGNREGS, which builds water conservation structures in rural areas.
โ Promote excellence through the National Water Awards, encouraging innovative water-saving practices.
๐ Conclusion
Indiaโs groundwater revival journey reflects the success of sustainable practices and collaborative efforts. By following the โReduce, Reuse, Recharge, and Recycleโ approach, India is working toward securing its water future and meeting global sustainability goals.
