India Groundwater Governance Case Study Summary

Core Content

This case study, titled India Groundwater Governance, is part of the World Bank's economic and sector analysis (ESW) titled "Too Big To Fail: The Paradox of Groundwater Governance". It aims to understand the challenges and opportunities in groundwater governance in India and to promote proactive reforms in its management. The study emphasizes the need for a shift from traditional supply-focused approaches to a more integrated, community-based, and sustainable management model.

Main Findings and Key Issues

Groundwater Overexploitation and Pollution

• Overexploitation: Groundwater is heavily used in both rural and urban areas, with 29% of assessment blocks classified as semi-critical, critical, or overexploited. This is driven by factors such as inadequate public irrigation, new pumping technologies, and government electricity subsidies.
• Pollution: Groundwater pollution is a growing threat, caused by industrial pollutants, human waste, agricultural chemicals, and geogenic contaminants like arsenic, fluoride, and iron. Pollution can render aquifers unusable even before depletion.
• Consequences: Continued weak or absent groundwater management could have severe socio-economic impacts, particularly on the poor. Climate change further complicates the situation by affecting recharge and availability.

Governance Framework

• Policy and Legal: The 1998 National Water Policy (NWP) and its 2002 amendment lack statutory status but are politically significant. Groundwater management is primarily under state jurisdiction, with the Central Groundwater Board (CGB) and Central Groundwater Authority (CGWA) playing key roles. However, the implementation capacity is weak.
• Institutional Capacity: State Groundwater Boards (SGBs) and agencies are under-resourced and lack coordination with other government bodies. There is a need for strengthening institutional capacity and fostering collaboration between different stakeholders.
• Legal Instruments: Groundwater protection is governed by a complex legal framework, including the 1974 Water (Prevention and Control of Pollution) Act and the 1986 Environmental Protection Act. However, enforcement remains a challenge.

Case Study Aquifers and Intensive Abstraction

• Selected Aquifers: The report focuses on eight pilot aquifers across different regions of India, including hard-rock rural and urban areas, and alluvial regions in the Indo-Gangetic Plain.
• Key Aquifers:
  • Weathered Deccan Traps Basalt in Maharashtra and Andhra Pradesh
  • Low-storage variably weathered crystalline basement aquifer in Tamil Nadu
  • Elevated alluvial areas in central Punjab
  • Deccan Traps basalt lava flows under Aurangabad
  • Layered sand-silt deposits in Uttar Pradesh
  • Thick Quaternary alluvial sands under Lucknow City

Lessons Learned

• Community-Based Management: Successful community-led initiatives have shown that local governance can effectively manage over-abstraction. These need to be scaled up and institutionalized.
• Integrated Approach: A more integrated approach to managing both quantity and quality of groundwater is essential.
• Conjunctive Use: Moving from spontaneous to planned conjunctive use of surface and groundwater can help adapt to climate change and reduce waterlogging and salinization.
• Awareness and Communication: Raising awareness among professionals and decision-makers and improving communication between researchers and stakeholders is crucial for effective groundwater management.
• Economic Incentives: Promoting economic incentives for sustainable use and addressing the "groundwater-energy nexus" can help improve management practices.

Climate Change Adaptation

• Conjunctive Use: Encouraging the use of surface and groundwater together can improve resilience to climate change.
• Recharge Enhancement: Enhancing groundwater recharge is a promising adaptation strategy, but its effectiveness in sustaining specific water sources must be evaluated.

Recommendations

For Intensive Groundwater Abstraction

• Mixed Management Approaches: A combination of management strategies is needed to address the diverse groundwater typologies.
• Demand Management: Implementing demand management practices, such as volumetric charging, can help control abstraction and generate revenue for new supply development.
• Institutional Strengthening: Strengthening the capacity of State Groundwater Development and Management Agencies (SGWDMAs) is critical for effective governance.

For Groundwater Pollution Protection

• Legal and Institutional Reforms: Legal frameworks are generally in place, but enforcement and coordination are lacking. The report suggests a national conference to bridge the gap between research and practice.
• Technological Solutions: Use of sophisticated models and experimental data can help remediate contaminated aquifers.
• Stakeholder Engagement: Encouraging community and stakeholder participation in decentralized management is essential for pollution control.

For Strengthening SGWDMAs

• Reorganization: SGWDMAs should be reorganized to enhance their role in groundwater protection.
• Political Commitment: Strong political support is needed to reduce bureaucratic barriers and promote a less water-demanding economy in critical areas.
• Central-State Coordination: Open dialogue with the central government is required to support state agencies in their groundwater governance roles.

Conclusion

The report highlights the need for a cultural shift in groundwater governance from top-down regulation to collaborative, community-based management. It stresses the importance of improving institutional capacity, enhancing awareness, and promoting integrated approaches to both quantity and quality management. With the right policies, funding, and cooperation, India can move towards a more sustainable and resilient groundwater governance system.
