🔆 Recycled Water as a Solution to India’s Water Crisis

📍 Why India Needs Recycled Water
✅ India’s annual per capita water availability fell to around 1,486 cubic metres in 2021 and is projected to decline further to nearly 1,367 cubic metres by 2031.
✅ This is below the water stress threshold of 1,700 cubic metres and moving close to the water scarcity benchmark of 1,000 cubic metres.
✅ Nine of India’s 20 river basins are already water-scarce.

📍 Major Challenges in India’s Water Sector
✅ Heavy dependence on groundwater: India uses more groundwater than the U. S. and China combined.
✅ Around one-fourth of India’s blocks face groundwater stress.
✅ Irrigation water-use efficiency in India is only about 38%, lower than the global average of 45%.
✅ Urban water systems lose nearly 39% of supplied water as “non-revenue water” through leakage and poor maintenance.

📍 Untapped Potential of Wastewater
✅ Indian cities generate nearly 72,000 million litres per day (MLD) of sewage.
✅ However, only around 27,000 MLD is currently treated.
❗ Thus, more than half of India’s wastewater remains untreated and wasted.

📍 Benefits of Treated Wastewater
✅ Recycled water can be used for:
• Irrigation
• Industrial use
• Urban landscaping
• Cooling in thermal plants and data centres
• Groundwater recharge

✅ According to a study by the Council on Energy, Environment and Water, if treated wastewater is used for irrigation:
• It could irrigate about 1.38 million hectares
• Generate nearly ₹96,600 crore in agricultural revenue
• Recover nutrients worth nearly ₹5,000 crore

📍 Government Initiatives
✅ The Prime Minister’s directions at the Third Chief Secretaries’ Conference encouraged States to promote use of treated wastewater for horticulture and vegetation within 10–50 km of peri-urban areas.
✅ Under the AMRUT Scheme, States are being encouraged to reuse:
• 20% of domestic treated water
• 50% of industrial effluents

📍 Successful Examples
✅ Several cities have already shown how treated wastewater can work:
• Bengaluru Water Supply and Sewerage Board
• Chennai Metropolitan Water Supply and Sewerage Board
• Nagpur Municipal Corporation
• Surat Municipal Corporation
• Prayagraj Municipal Corporation

📍 Key Problems in Expanding Reuse
✅ India still faces several barriers:
• Inadequate treatment infrastructure
• Poor financing and tariffs
• Lack of common quality standards
• Weak public acceptance of recycled water
• Absence of strong monitoring systems

❗ Only 1 out of 36 States and Union Territories currently has a dedicated policy for wastewater reuse.

📍 New Area of Demand: Data Centres
✅ Data centres require huge quantities of water for cooling.
✅ India’s data centre capacity is expected to rise to nearly 19 GW by 2030.
✅ Therefore, treated wastewater can become an important alternative source for cooling without increasing pressure on freshwater supplies.

📍 Way Forward
✅ India needs a circular water economy where wastewater is seen not as waste, but as a resource.
✅ Required measures include:
• Expanding sewage treatment plants
• Framing State-level reuse policies
• Ensuring quality standards and monitoring
• Incentivising industries and cities to use treated water
• Improving public awareness and acceptance

❗ The article argues that recycled water is no longer optional for India—it is essential for long-term water security, climate resilience and sustainable development.

🔆 Mains Practice Question
📍 “Treated wastewater can become a critical pillar of India’s future water security.” Examine the potential of recycled water in addressing India’s water scarcity. Also discuss the challenges in creating a circular water economy. (250 words) #GS3

🔆 India Leads the World in Compliance Certificates under the Nagoya Protocol

📍 What Has Happened?
❗ India has become the global leader in issuing Internationally Recognized Certificates of Compliance (IRCCs) under the Nagoya Protocol.
❗ India has issued 3,561 IRCCs out of 6,311 issued globally.
❗ This means India accounts for more than 56% of all such certificates worldwide.

📍 What are IRCCs?
✅ IRCCs are official certificates issued when a country allows access to its genetic resources or traditional knowledge.
✅ They confirm that:
• Prior Informed Consent (PIC) has been taken
• Mutually Agreed Terms (MAT) have been established
• Benefits from the use of biological resources will be shared fairly

📍 Why are These Certificates Important?
❗ IRCCs help track how biological and genetic resources are used—from research to commercial products.
❗ They ensure that companies or researchers using a country’s biodiversity share the benefits with that country.
❗ This prevents biopiracy and exploitation of indigenous knowledge.

📍 Global Ranking
✅ Top countries issuing IRCCs:
1. India – 3,561
2. France – 964
3. Spain – 320
4. Argentina – 257
5. Panama – 156
6. Kenya – 144

📍 What is the Nagoya Protocol?
✅ It is an international agreement under the Convention on Biological Diversity.
✅ It aims to ensure fair and equitable sharing of benefits arising from the use of genetic resources.
✅ It came into force in 2014.

📍 How Has India Achieved This?
❗ India has implemented a strong Access and Benefit Sharing (ABS) system under the

Biological Diversity Act, 2002

✅ The system works through:
• National Biodiversity Authority at the central level
• State Biodiversity Boards at the State level
• Biodiversity Management Committees at the local level

📍 Why is This Significant for India?
✅ Strengthens India’s position in global biodiversity governance
✅ Protects India’s rich traditional knowledge and biological resources
✅ Supports local communities by ensuring benefit-sharing
✅ Enhances India’s image as a responsible participant in global environmental agreements

📍 UPSC Angle
❗ The topic is important for questions related to:
✅ Biodiversity conservation
✅ International environmental agreements
✅ Biopiracy and traditional knowledge
✅ Biological Diversity Act and Nagoya Protocol

📝 Mains Practice Question
“The Nagoya Protocol seeks to balance biodiversity conservation with equitable benefit-sharing.” Examine India’s performance in implementing the Protocol.

🔆 Solid Waste Management Rules, 2026 to Come into Force from April 1 (GS3 – Environment / Governance)

📍 What Has Changed?
❗ The Ministry of Environment, Forest and Climate Change has notified the new Solid Waste Management Rules, 2026, replacing the 2016 rules.
❗ The new rules will come into effect from April 1, 2026.
❗ They are based on the principles of circular economy and Extended Producer Responsibility (EPR).

📍 Four-Stream Waste Segregation Made Mandatory
✅ Every household and institution must now segregate waste into:
• Wet waste
• Dry waste
• Sanitary waste
• Special-care waste

❗ This is stricter than the earlier system and aims to improve waste collection and recycling.

📍 New Responsibility for Bulk Waste Generators
❗ Large institutions, apartment complexes, industries and commercial establishments have been classified as “bulk waste generators”.
❗ They must now ensure that the waste they generate is collected, transported and processed properly.
❗ This is called Extended Bulk Waste Generator Responsibility.

📍 Digital Tracking of Waste
✅ All stages of solid waste management will be monitored through a Centralised Online Portal.
❗ The portal will track:
• Collection
• Transportation
• Processing
• Disposal

📍 Changes for Industries and Waste-to-Energy Plants
❗ Industrial units, including cement plants and waste-to-energy plants, must increase the use of Refuse Derived Fuel (RDF).
❗ The fuel substitution rate will rise from 5% to 15% over the next six years.

📍 Stronger Action on Landfills and Legacy Waste
✅ States and local bodies must prepare time-bound plans to remove legacy waste.
❗ The rules place stronger restrictions on dumping waste in landfills.
❗ Special provisions have also been added for hilly areas and islands.

📍 Polluter Pays Principle Introduced
❗ Environmental compensation can now be imposed on those violating the rules.
❗ This is based on the
Polluter Pays Principle

which means the polluter must bear the cost of environmental damage.

📍 Institutional Mechanism
✅ Separate Central and State-level Committees will monitor implementation.
✅ The Central Pollution Control Board has already formed a Central Implementation Committee.

📍 Why These Rules Matter
❗ India faces serious problems of landfill overflow, unsegregated waste and legacy garbage dumps.
❗ The 2026 Rules attempt to shift India from simple waste disposal to scientific waste management and recycling.
❗ Effective implementation can help reduce pollution, improve public health and support a circular economy.

📝 Mains Practice Question
“The Solid Waste Management Rules, 2026 mark a shift from disposal-based waste management to circular economy-based waste governance.” Discuss.

🔆 Tepid Promises: India’s Battery Storage Gap

📍 Context
✅ India updated its NDC targets (2031–35) under Paris Agreement
✅ Ambition ↑ but execution gap persists, especially in energy storage

📍 India’s Climate Commitments
✅ 47% reduction in emissions intensity (from 2005 levels)
✅ 60% installed power capacity from non-fossil sources by 2035
✅ Carbon sink: 3.5–4 billion tonnes CO₂ eq.
✅ Net-zero target → 2070

📍 The Core Problem
⚠️ Despite ~52% installed non-fossil capacity,
➡️ Only ~25% actual electricity generation is non-fossil

👉 Reason: Lack of Battery Storage & Grid Limitations

📍 Why Storage Matters?
✅ Solar & wind are intermittent
✅ Without storage → energy wastage + underutilisation
✅ Storage ensures:
✔️ Grid stability
✔️ Round-the-clock renewable supply
✔️ Reduced fossil fuel dependence

📍 Key Concerns Highlighted
❗ Over-reliance on installed capacity numbers (not actual output)
❗ Weak grid infrastructure & integration
❗ Slow progress in battery ecosystem
❗ Risk of greenwashing without real transition

📍 Strategic Implications
✅ Energy security still tied to fossil fuels (esp. imports)
✅ West Asia conflicts expose vulnerability
✅ Renewable transition incomplete without storage backbone

📍 Way Forward
✅ Scale up battery storage systems (BESS)
✅ Invest in grid modernisation & smart grids
✅ Promote domestic battery manufacturing (PLI, R&D)
✅ Integrate renewables + storage planning
✅ Encourage hybrid projects (solar + wind + storage)

📝 Mains Practice Question (GS3)
“India’s renewable energy transition is constrained more by storagand grid issues than generation capacity.” Critically examine.
