  • India’s direction for disaster resilience

    Introduction

    India’s approach to disaster management has entered a new phase, one that focuses not only on response and recovery but equally on risk reduction, preparedness, and resilience. With climate change intensifying heat waves, floods, and landslides, the country’s policy architecture, led by the Ministry of Home Affairs (MHA) and the National Disaster Management Authority (NDMA), has embraced a multi-hazard, multi-stakeholder, and science-backed model. The guiding compass remains the Prime Minister’s Ten-Point Agenda on Disaster Risk Reduction (2016), now reinforced by major financial and institutional reforms.

    Why in the News

    For the first time, India’s disaster management strategy has been fully integrated into public finance planning, through the 15th Finance Commission’s ₹2.28 lakh crore allocation for disaster risk reduction over five years. This is a paradigm shift: from ad hoc post-disaster relief to structured, science-driven, and nature-based risk mitigation. With new funding for fire safety, glacial risk monitoring, and bioengineering-led landslide prevention, the government’s efforts represent a bold move towards building a climate-resilient India. The initiative is also significant because it establishes clear budget-to-project chains, accountability mechanisms, and cross-institutional linkages, something missing in previous regimes.

    India’s Evolving Disaster Management Framework

    1. Multi-hazard nation: India faces diverse risks, floods, droughts, landslides, heat waves, cyclones, necessitating a multi-faceted approach.
    2. Shift in focus: Earlier systems were relief-centric; now, they integrate prevention, mitigation, capacity building, and sustainable reconstruction.
    3. Institutional leadership: The MHA and NDMA lead both pre- and post-disaster phases, ensuring coordination across States and institutions.
    4. Guiding vision: The Prime Minister’s Ten-Point Agenda (2016) promotes risk-informed investments, community participation, and technology integration.

    How the 15th Finance Commission Redefined Disaster Financing

    • Historic allocation: ₹2.28 lakh crore ($30 billion) allocated over five years, a landmark in linking public finance with disaster resilience.
    • Segmented approach:
      • Preparedness and Capacity Building – 10%
      • Mitigation – 20%
      • Response – 40%
      • Reconstruction – 30%
    • End of debt dependency: Earlier, post-disaster reconstruction relied on multilateral loans; now, domestic fiscal mechanisms fill that gap.
    • Five priority reforms:
      1. Evaluate multi-hazard risks and prioritize them.
      2. Integrate scientific mitigation models into fiscal systems.
      3. Avoid duplication with other schemes.
      4. Enhance Centre-State and institutional synergy.
      5. Ensure light-touch regulation for flexibility and speed.

    Investing in Pre-Disaster Preparedness and Capacity Building

    1. Fire safety modernization: ₹5,000 crore earmarked for upgrading urban and rural fire infrastructure.
    2. Community-based volunteers: Apda Mitra and Yuva Apda Mitra programs train 2.5 lakh volunteers to act as first responders.
    3. Strengthening institutions:
      1. National Institute of Disaster Management (NIDM) given a central role with geo-spatial training labs and action-based research.
      2. 36 streams of disaster management courses were introduced to mainstream DRR down to the panchayat level.
    4. Outcome: Shift from theoretical to practical, localised risk management.

    Nature-Based Solutions and Climate Adaptation

    1. ₹10,000 crore mitigation projects across States emphasize nature-based, long-term solutions.
    2. Bioengineering for landslides: Stabilizing slopes in Himalayan regions using vegetation and soil binding.
    3. Urban flood control: Revitalizing water bodies and green spaces to restore natural drainage.
    4. Glacial lake monitoring: Remote sensing and automated stations for real-time surveillance.
    5. Forest fire prevention: Creating break lines, rejuvenating water bodies, and fuel evacuation corridors.
    6. Brahmaputra beels rejuvenation: Ecological restoration to mitigate monsoon flooding.
    7. Precursor success: National Cyclone Mitigation Programme (2011–22): ₹5,000 crore initiative, drastically reduced coastal vulnerability through shelters, embankments, and early warnings.

    Building Technological and Institutional Resilience

    1. Advanced early warning systems: Multi-hazard platforms with seven-day lead time for cyclones.
    2. Common Alerting Protocol: Delivers region-specific alerts in local languages via multi-media.
    3. Human resource development:
      • Training at NIDM, NDRF Academy, and National Fire Service College for hundreds of officers annually.
      • Mock drills, school safety programmes, and local awareness drives improve community response.
      • Network of 327 universities: Build research and innovation pipelines for disaster science and policy.

    India’s Global Leadership in Disaster Resilience

    1. Coalition for Disaster Resilient Infrastructure (CDRI): India-led global initiative for climate-resilient infrastructure systems.
    2. Active participation: G-20, SCO, BIMSTEC, and IORA platforms for sharing best practices.
    3. Knowledge exchange: India’s experience in nature-based DRR and community-driven risk management now shaping global policy dialogues.

    Conclusion

    India’s journey from disaster relief to disaster resilience marks a tectonic policy evolution. With fiscal integration, scientific innovation, and community participation, the nation is shifting from reactive recovery to proactive risk management. The emerging focus on nature-based, sustainable, and locally-driven mitigation reflects India’s understanding that resilience is not built after a disaster, it is cultivated every day, across every sector.

  • India’s clean energy rise needs climate finance expansion

    Introduction

    India’s clean energy story has entered a defining phase. With 24.5 GW of solar capacity added in 2024, India now stands as the third-largest solar power contributor in the world, after China and the U.S. This achievement reflects not only technological progress but also the country’s growing global leadership in renewable energy. Yet, behind this success lies a serious constraint, the widening climate finance gap, estimated at over $2.5 trillion by 2030. Without adequate and innovative financing, India’s clean energy momentum risks slowing down, threatening its ability to stay on course for its 1.5°C-aligned climate targets.

    Why in the News

    India added 24.5 GW of solar capacity in 2024, emerging as the third largest contributor globally, after China and the U.S., a historic leap for a developing country. Recognised in the UN Secretary-General’s 2025 Climate Report alongside Brazil and China, India has shown that clean energy growth can power both employment (over 1 million jobs) and GDP (5% contribution). However, the optimism hides a crisis: a climate finance gap exceeding $2.5 trillion by 2030, threatening to stall India’s 1.5°C-aligned pathway. The stakes are massive — India’s global credibility, energy security, and development model now depend on how swiftly it can scale climate finance.

    The Economic Momentum of India’s Clean Energy Transition

    1. 24.5 GW solar addition (2024): Makes India the third-largest solar contributor globally, marking a defining milestone in renewable energy leadership.
    2. Global recognition: The UN 2025 Climate Report identifies India as a leading developing nation in scaling solar and wind energy.
    3. Employment boost: Renewable energy employed over 1 million people in 2023, with off-grid solar alone employing 80,000 (2021).
    4. GDP contribution: Renewables added 5% to India’s GDP growth, underscoring its macroeconomic importance.
    5. International Solar Alliance (ISA): India’s leadership in creating ISA has positioned it as a norm-setter in global clean energy diplomacy.

    Where Lies the Climate Finance Gap?

    Massive funding shortfall:

    1. $1.5 trillion required (IRENA) by 2030 for a 1.5°C pathway.
    2. $2.5 trillion+ estimated by the Ministry of Finance for national targets — double the earlier projections.
    3. Finance distribution gaps: Needed for battery storage, green hydrogen, grid strengthening, sustainable agriculture, and transport transition.

    Green bonds surge:

    1. Cumulative GSS+ debt issuance: $55.9 billion (2024), up 186% since 2021.
    2. Green bonds: Account for 83% of total sustainable issuance.
    3. Private sector dominance: 84% of green bond issuance.
    4. Key concern: MSMEs and agri-tech innovators face barriers in accessing concessional finance and risk-sharing tools.

    How Can India Unlock Climate Finance?

    1. Public finance as catalyst: National and State governments must use budget allocations and fiscal incentives to de-risk green investments.
    2. Blended finance models:
      • Credit enhancement tools (partial guarantees, subordinated debt) to improve risk-return profiles.
      • Performance or loan guarantees to unlock finance for Tier II & III cities.
    3. Domestic institutional capital:
      • Mobilising funds from EPFO, LIC, pension and insurance funds for green portfolios.
      • Requires regulatory reforms, ESG frameworks, and green project pipelines.

    Policy Innovations and Carbon Market Potential

    • Carbon Credit Trading Scheme: Offers a new finance stream, provided it remains transparent, regulated, and equitable.
    • Adaptation and Loss & Damage Financing: Focus must extend beyond mitigation to resilience building.
    • Tech-driven climate finance: 
      • Use of Blockchain for finance tracking.
      • AI-based risk assessment for green portfolios.
      • Tailored blended finance suited to India’s socio-economic landscape.

    Private Sector and Sovereign Initiatives in Climate Finance

    1. Sovereign Green Bonds: Successful issuance has crowded-in private capital for green projects.
    2. SEBI-regulated Social Bonds: Directed funds to education, healthcare, and climate action.
    3. Solar Park Scheme: Competitive auctions have encouraged private investment in large-scale solar infrastructure.

    Conclusion

    India’s clean energy transition stands at a defining crossroad — its success no longer depends on technology or intent, but on finance. The renewable boom has demonstrated economic and employment dividends, but without a parallel rise in climate finance mechanisms, it risks plateauing. To sustain momentum, India must blend innovation, public-private synergy, and institutional capital. The clean energy rise must now be matched by a climate finance revolution.

    PYQ Relevance

    [UPSC 2022] Do you think India will meet 50 percent of its energy needs from renewable energy by 2030? Justify your answer. How will the shift of subsidies from fossil fuels to renewables help achieve the above objective? Explain.

    Linkage: The article complements the 2022 question by highlighting that India’s progress toward meeting 50% renewable energy by 2030 hinges on bridging its $2.5 trillion climate finance gap.

  • Cost of convenience, health hazards a a side effect of using digital tools

    Introduction

    India’s embrace of the digital revolution has been rapid and transformative. From smartphones to smart homes, electronics have become integral to urban living. However, this transformation carries a dark underbelly: the mounting crisis of e-waste. In 2025, India generated 2.2 million tonnes of e-waste, becoming the third-largest generator globally, after China and the United States. Despite having a formal recycling capacity of over 2.2 million MT, more than half of India’s e-waste is still processed informally, exposing millions to toxic substances. The issue is not just environmental but also a public health catastrophe, disproportionately affecting the poor and marginalised.

    Why is e-waste in the news?

    India’s e-waste problem is no longer a distant warning but an immediate crisis. The country has seen a 150% surge in e-waste since 2017–18 (0.71 MT to 2.2 MT in 2025), with projections of doubling by 2030. Cities like Seelampur (Delhi), Moradabad (UP), and Bhiwandi (Maharashtra) have emerged as hotspots of informal recycling, where toxic fumes and crude dismantling methods poison both workers and residents. Despite 322 formal recycling units, informal handlers dominate the sector, creating one of the sharpest contrasts between policy design and ground reality.

    The Escalating Burden of E-Waste

    1. Third-largest generator: India stands only behind China and the U.S., producing 2.2 MT of e-waste in 2025.
    2. Rapid growth: A 150% surge in seven years, expected to double by 2030.
    3. Urban hotspots: Over 60% of e-waste originates from just 65 cities; major hubs include Seelampur, Mustafabad, Moradabad, and Bhiwandi.

    Why informal recycling is a ticking time bomb

    1. Crude methods: Manual dismantling, open burning, and acid leaching without protective equipment.
    2. Toxic substances: Release of over 1,000 hazardous chemicals, including heavy metals (lead, cadmium, mercury, chromium), POPs (dioxins, furans), and fine particulate matter (PM₂.₅ and PM₁₀).
    3. Alarming air quality: PM₂.₅ levels in Seelampur exceed 300 µg/m³ — over 12 times higher than WHO’s safe limit of 25 µg/m³.

    How does e-waste impact human health?

    1. Respiratory illnesses: Workers show 76–80% prevalence of chronic bronchitis, asthma, persistent coughing (MDPI Applied Sciences, 2025).
    2. Neurological damage: Lead exposure linked to cognitive impairment, reduced IQ, attention deficits. WHO warns millions of children are at risk.
    3. Skin & ocular disorders: Rashes, burns, dermatitis; in Guiyu (China), exposure linked to miscarriages and preterm births.
    4. Genetic and systemic effects: DNA damage, oxidative stress, altered immune functions; children show higher vulnerability.
    5. Syndemic environment: E-waste risks compound poverty, malnutrition, and unsafe housing, worsening outcomes for urban poor.

    Policy response: Progress and gaps

    1. E-Waste (Management) Rules, 2022: Strengthened Extended Producer Responsibility (EPR), mandatory registration, incentives for formalisation.
    2. Weak enforcement: As of 2023–24, only 43% of e-waste was officially processed.
    3. Legal hurdles: Capping of EPR credit prices led to legal disputes with manufacturers.
    4. Gap: Informal handlers still dominate, undermining scientific recycling capacity.

    The Way Forward

    1. Formalise the informal: Integrate kabadiwalas through skill certification, PPE provision, healthcare, social security.
    2. Strengthen enforcement: Empower Pollution Control Boards, mandate digital tracking & audits.
    3. Expand medical surveillance: Health camps and long-term studies, especially on children in hotspots.
    4. Foster innovation: Promote local recycling technologies, decentralised treatment hubs.
    5. Raise awareness: Mass campaigns and school-level education on e-waste.

    Conclusion

    India’s digital empowerment cannot come at the cost of environmental collapse and human suffering. The e-waste crisis is not only a question of waste management but also of justice and public health. Unless India formalises its informal sector, strengthens enforcement, invests in technology, and raises awareness, the cost of convenience will continue to erode both ecosystems and human dignity.

    PYQ Relevance

    [UPSC 2018] What are the impediments in disposing the huge quantities of discarded solid wastes which are continuously being generated? How do we remove safely the toxic wastes that have been accumulating in our habitable environment?

    Linkage: The article on e-waste directly links to this PYQ as it highlights impediments like dominance of informal recycling, weak enforcement of E-Waste Rules, and lack of awareness, while also suggesting safe disposal measures such as formalisation, digital tracking, PPE use, decentralised hubs, and scientific recycling methods.

  • Geoengineering Proposals for Polar Regions found flawed

    Why in the News?

    A University of Exeter study found five major polar geoengineering methods ineffective and risky, failing criteria for responsible climate intervention.

    Geoengineering in Polar Regions: Study Findings

    Method Description Intended Benefit Key Findings & Limitations
    Stratospheric Aerosol Injection (SAI) Artificially releasing aerosols (SO₂, sulphur particles, TiO₂, CaCO₃) into the stratosphere to reflect sunlight. Reduce surface temperatures by blocking solar radiation.
    • Ineffective in polar winters (no sunlight) and of limited use in summers (ice already highly reflective).
    • Sudden termination can cause “termination shock” with rapid global warming.
    • Potential to disrupt global weather cycles, harming food and water security.
    • No global governance on costs or liability. Estimated cost: $55M/year per country (if 30 nations share).
    Sea Curtains / Sea Walls Massive buoyant barriers anchored to seafloor to block warm currents from reaching ice sheets. Slow melting of glaciers by insulating them from warm water.
    • Technically near-impossible in remote seas like Amundsen (Antarctica).
    • Extremely high costs — >$1 billion/km.
    • Threatens marine circulation, fish migration, and nutrient cycles.
    • Installation in harsh polar seas only possible for few months a year; requires custom-built ships.
    • Risk of toxic materials leaching into ocean.
    Sea Ice Management (Microbeads) Sprinkling glass microbeads over sea ice to increase albedo (reflectivity) and thicken ice. Preserve summer ice, slow down warming.
    • Requires 360M tonnes of beads annually — equal to world’s plastic production.
    • Major logistical and emissions challenges.
    • Beads dissolve quickly, reducing effectiveness.
    • Some studies show beads absorb sunlight, causing net warming.
    • Costly: $500B/year for Arctic deployment; requires 100M pumps, huge energy draw.
    Basal Water Removal Pumping subglacial meltwater from under Antarctic glaciers. Reduce glacier sliding, thus slowing sea-level rise.
    • Flawed logic: subglacial water is constantly replenished by frictional/geothermal heating.
    • Highly emissions-intensive and energy-consuming.
    • Requires continuous monitoring, maintenance, and heavy infrastructure.
    • Long-term sustainability questioned.
    Ocean Fertilisation Adding nutrients (e.g., iron) to stimulate phytoplankton growth, enhancing CO₂ absorption. Sequester more carbon in oceans.
    • No control over which phytoplankton species dominate, creating food chain imbalances. 
    • Could harm marine biodiversity and alter global nutrient cycles.
    • Needs deployment at massive, impractical scale.
    • Risk of side-effects outweighs uncertain benefits.

     

    [UPSC 2020] Consider the following activities:

    1. Spreading finely ground basalt rock extensively on farmlands

    2. Increasing the alkalinity of oceans by adding lime

    3. Capturing carbon dioxide released by various industries and pumping it into abandoned subterranean mines in the form of carbonated waters

    How many of the above activities are often considered and discussed for carbon capture and sequestration?

    Options: (a) Only one (b) Only two (c) All three* (d) None
