Practice Question
Q1.“Decentralised water harvesting is key to addressing India’s groundwater crisis.”Discuss with reference to recent initiatives. (250 words)
Overview
- India has created ~50 lakh decentralised water harvesting structures (2015–2026) including check dams, farm ponds, recharge shafts to enhance groundwater recharge.
- Under Mission Amrit Sarovar (2022–), over 70,000 lakes developed/rejuvenated, exceeding target of 75 per district, focusing on ecological restoration and community assets.
- Complementary initiative “Catch the Rain” promotes localised water conservation with slogan “where it falls, when it falls,” strengthening seasonal preparedness.
- These initiatives reflect a paradigm shift from large dam-centric model to decentralised, community-led water governance.
- Groundwater remains critical: ~60% irrigation and 85% drinking water depend on it, making recharge-focused interventions essential.
- Nearly 14% of groundwater blocks classified as ‘over-exploited/critical’ (2023); these initiatives aim to reverse this trend.
- Amrit Sarovars are geo-tagged and monitored digitally, improving transparency, accountability, and maintenance tracking.
- Standardised design: minimum 1 acre area, ~10,000 cubic metre capacity, ensuring functional storage and recharge potential.
- Social dimension: Sarovars act as community spaces (plantation, recreation, flag hoisting), enhancing local ownership and sustainability.
Static Background
Water Stress in India
- India hosts 18% population but only 4% freshwater resources, making it water-stressed.
- Per capita water availability declined from 5,177 m³ (1951) to ~1,486 m³ (2021), approaching water-scarcity threshold.
Groundwater Crisis
- India is largest groundwater extractor globally, accounting for ~25% of global extraction.
- Over-extraction driven by subsidised electricity, MSP-driven cropping patterns, and lack of regulation.
Decentralised Water Management
- Emphasises local storage, recharge, watershed management, aligning with Gandhian principle of “local self-sufficiency in resources.”
- Key mechanisms: check dams (slow runoff), farm ponds (store rainwater), recharge shafts (aquifer replenishment).
Significance / Impact
- Enhances water security by increasing groundwater recharge and reducing dependency on erratic monsoons.
- Supports climate resilience, mitigating drought risks and stabilising agricultural productivity.
- Promotes community participation and behavioural change, key for sustainable resource management.
- Reduces flood-drought cycle intensity by improving local water retention and reducing runoff losses.
- Strengthens rural livelihoods through improved irrigation availability and allied activities (fisheries, plantations).
Challenges / Criticisms
- Maintenance deficit: Many structures face siltation and neglect, reducing long-term effectiveness.
- Uneven regional impact: High-performing states vs lagging regions due to governance and capacity differences.
- Quality concerns: Rapid construction may compromise design standards and recharge efficiency.
- Data gaps: Limited scientific assessment of actual groundwater recharge impact at basin level.
- Institutional fragmentation: Multiple ministries (Jal Shakti, Rural Development, Agriculture) with weak convergence.
- Behavioural inertia: Continued over-extraction undermines conservation gains.
Way Forward
- Institutionalise annual desilting and maintenance audits with community participation and MGNREGA convergence.
- Strengthen aquifer mapping (NAQUIM) and data-driven planning to align structures with hydrogeological realities.
- Promote water budgeting at Panchayat level, linking usage with recharge capacity.
- Integrate conservation efforts with crop diversification and micro-irrigation (PMKSY) to reduce demand-side pressure.
- Enhance real-time monitoring using remote sensing and GIS dashboards for impact evaluation.
- Encourage community ownership through Water User Associations (WUAs) and local governance institutions.
Prelims Pointers
- Mission Amrit Sarovar (2022): 75 water bodies per district target.
- Jal Sanchay Abhiyan: Focus on decentralised water harvesting structures.
- Catch the Rain campaign: Seasonal conservation initiative.
- Groundwater dependency: ~60% irrigation, ~85% drinking water.
- Over-exploited blocks: ~14% (CGWB classification).
