The Namami Gange and National mission for clean Ganga (NMCG) programmes and causes of mixed results from the previous schemes. What quantum leaps can help preserve the river Ganga better than incremental inputs?

Introduction

The Ganga River, often referred to as the lifeline of India, holds immense cultural, ecological, and economic significance. However, it has been plagued by severe pollution due to untreated sewage, industrial effluents, and agricultural runoff. The Namami Gange Programme (2014) and the National Mission for Clean Ganga (NMCG) were launched to rejuvenate the river, building on lessons from earlier schemes like the Ganga Action Plan (1986). While some progress has been made, challenges persist, necessitating a shift from incremental measures to quantum leaps for sustainable preservation.

Key Dimensions at a Glance

Achievements of Namami Gange and NMCG

• Infrastructure Development: Over 4,000 MLD sewage treatment capacity created, with 177 projects sanctioned (NMCG Report, 2022).
• Riverfront Development: Beautification and ghats rejuvenation in cities like Varanasi and Haridwar.
• Community Engagement: Initiatives like Ganga Praharis and Ganga Task Force have fostered local participation.
• Reduction in Pollution: Decline in Biochemical Oxygen Demand (BOD) levels in certain stretches, e.g., Kanpur and Varanasi.
• Afforestation: Over 26,000 hectares of land afforested to improve the river basin ecosystem.

Challenges and Causes of Mixed Results from Previous Schemes

1. Inadequate Sewage Management

• Reason: Only 60% of urban sewage is treated before entering the river.
• Example: Cities like Kanpur and Patna still discharge untreated waste.

2. Industrial Effluents

• Reason: Poor enforcement of pollution control norms for industries like tanneries and textiles.
• Example: Chromium contamination from Kanpur tanneries.

3. Fragmented Governance

• Reason: Overlapping jurisdictions between central, state, and local bodies.
• Example: Lack of coordination between NMCG and urban local bodies.

4. Limited Public Awareness

• Reason: Insufficient behavioral change campaigns to reduce waste dumping.
• Example: Continued immersion of idols and religious offerings.

5. Funding and Maintenance Gaps

• Reason: Delays in fund disbursement and lack of operational sustainability for STPs.
• Example: Non-functional STPs in smaller towns.

6. Focus on Urban Areas

• Reason: Neglect of rural pollution sources like agricultural runoff and open defecation.

Lessons from Past Schemes

• Ganga Action Plan (1986): Focused on STPs but ignored industrial pollution and community participation.
• National River Conservation Plan (NRCP): Lacked a basin-wide approach and faced delays in project execution.
• Yamuna Action Plan: Highlighted the need for stricter enforcement of pollution norms.

Quantum Leaps for Better Preservation of Ganga

1. Integrated Basin Management

• What: Adopt a basin-wide approach involving all tributaries and stakeholders.
• How: Establish a Ganga River Basin Authority for unified governance.

2. Decentralized Sewage Treatment

• What: Promote decentralized STPs in smaller towns and rural areas.
• How: Use bio-digesters and constructed wetlands for cost-effective treatment.

3. Industrial Pollution Control

• What: Enforce zero liquid discharge (ZLD) norms for industries.
• How: Use real-time monitoring systems and impose heavy penalties for violations.

4. Community-Led Conservation

• What: Strengthen local participation through eco-tourism and livelihood programs.
• How: Expand initiatives like Ganga Praharis and incentivize waste segregation.

5. Technological Innovations

• What: Leverage AI and IoT for real-time water quality monitoring.
• How: Deploy drones for surveillance of illegal dumping and encroachments.

6. Agricultural Reforms

• What: Reduce agricultural runoff by promoting organic farming and micro-irrigation.
• How: Provide subsidies for bio-fertilizers and drip irrigation systems.

7. Sustainable Financing

• What: Ensure long-term funding through public-private partnerships (PPP).
• How: Introduce green bonds and involve corporates under CSR initiatives.

Conclusion

Preserving the Ganga requires a paradigm shift from piecemeal efforts to holistic, technology-driven, and community-centric approaches. By integrating sustainable practices, leveraging innovations, and ensuring coordinated governance, the river can be restored to its pristine glory, aligning with SDG 6 (Clean Water and Sanitation) and India's vision of environmental sustainability.
