    Why in the News?

    Chhattisgarh launched a five-year Blackbuck Reintroduction Plan (2021–2026) at Barnawapara Wildlife Sanctuary to revive the species after 50 years of local extinction.

    Blackbucks have vanished from Chhattisgarh by the 1970s, primarily due to poaching, habitat loss, and grassland encroachment.

    About the Blackbuck (Antilope cervicapra):

    • Habitat: Native to India and Nepal, commonly found in Rajasthan, Gujarat, Madhya Pradesh, Odisha, and Tamil Nadu.
    • Physical Traits: Medium-sized antelope with males having spiral horns and black coats; known as the fastest land mammal in India.
    • Behaviour: Diurnal grazer that thrives in open plains and grasslands.
    • Ecological Role: Serves as an indicator species for grassland ecosystem health.
    • State Animal: Designated as the State Animal of Punjab, Haryana, and Andhra Pradesh.
    • Cultural Symbolism: Represents purity in Hinduism and good fortune in Buddhism.
    • Legal Protection:
      • Wildlife (Protection) Act, 1972: Schedule I.
      • IUCN Red List: Least Concern.
      • CITES: Appendix III.

  • Carbon Di-oxide Levels in 2024 set new records: WMO

    Why in the News?

    The World Meteorological Organization (WMO) reported that carbon dioxide (CO₂) concentrations reached a record 423.9 ppm in 2024, marking the highest annual increase (3.5 ppm) since global measurements began in 1957.

    About WMO Report 2025:

    • Publisher: Issued by the World Meteorological Organization (WMO), the UN specialised agency for weather, climate, and water systems.
    • Document: The 2025 Greenhouse Gas Bulletin presents global atmospheric data for carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O).
    • Global Record: Confirms 2024 as the warmest year ever, with average temperatures 1.55 °C above pre-industrial (1850–1900) levels.
    • Context & Timing: Released ahead of COP30 (Belém, Brazil) to guide mitigation policies and national climate commitments.
    • Key Warning: Notes a record surge in CO₂ and the weakening of natural carbon sinks such as oceans and forests.

    Key Highlights about Greenhouse Gases:

    • Carbon Dioxide (CO₂): Global mean reached 423.9 ppm in 2024, up 3.5 ppm from 2023, the largest annual rise since 1957. Concentrations are 152 % above pre-industrial (278.3 ppm); land and ocean sinks are declining in efficiency.
    • Methane (CH₄): Climbed to 1,942 ppb, 166 % above pre-industrial levels; ~60 % of emissions stem from livestock, fossil fuels, and rice cultivation.
    • Nitrous Oxide (N₂O): Reached 338 ppb, 25 % higher than pre-industrial; emitted mainly from fertiliser use, biomass burning, and industry; the third major long-lived GHG.
    • Drivers of Increase: Human emissions, El Niño-linked droughts and wildfires, and reduced oceanic absorption, especially from the Amazon and southern Africa in 2024.

    Implications and Risks:

    • Warming Acceleration: CO₂ causes ~66 % of total warming and 79 % over the last decade; persistent buildup locks in long-term temperature rise.
    • Weakening Carbon Sinks: Warmer seas and drought-stricken lands absorb less CO₂, reinforcing a feedback loop of accumulation.
    • Extreme Events: Intensified heatwaves, floods, droughts, and wildfires signal proximity to irreversible tipping points like ice-sheet loss and coral die-off.
    [UPSC 2012] The increasing amount of carbon dioxide in the air is slowly raising the temperature of the atmosphere, because it absorbs

    Options: (a) the water vapour of the air and retains its heat.

    (b) the UV part of the solar radiation.

    (c) all the solar radiations.

    (d) the infrared part of the solar radiation. *

     

  • CG HC upholds cancellation of Forest Rights of Villagers

    Why in the News?

    The Chhattisgarh High Court has dismissed a petition challenging the cancellation of Community Forest Rights (CFRs) granted to villagers of Ghatbarra in the Hasdeo Arand forest, an area where Adani Enterprises–linked coal mines operate.

    Background of the Case:

    • Dispute Origin: The District-Level Committee (DLC) revoked CFR titles in 2016, citing that the area had already been diverted for mining in 2012 with MoEF clearance.
    • Petitioners’ Claim: The Hasdeo Arand Bachao Sangharsh Samiti argued that the Forest Rights Act (FRA), 2006 provides no revocation clause and that villagers were not given a fair hearing before cancellation.
    • Court’s View: The High Court upheld the State’s decision, calling the 2013 CFR grant a “mistake” void ab initio, and legally cancellable.

    Key Judicial Findings:

    • Legality of Revocation: FRA lacks explicit revocation provision, but erroneous grants may be rectified; hence cancellation was valid.
    • Prior Approvals Prevail: 2012 MoEFCC mining clearance overrode subsequent CFR grants.
    • State Mineral Ownership: FRA does not affect the State’s control over minerals beneath forest land.
    • Locus Standi: Petitioners lacked standing after the Forest Rights Committee withdrew; no authorised village representation remained.
    • Suppression of Facts: Petitioners had earlier challenged land acquisition (case dismissed in 2022) but failed to disclose it.

    Significance:

    This ruling marks the first judicial interpretation of whether forest rights granted under the Forest Rights Act, 2006 (FRA) can be revoked or cancelled, despite the Act containing no explicit provision for cancellation.

    About the Forest Rights Act (FRA), 2006:

    • Overview: The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, commonly called the Forest Rights Act (FRA).
    • Purpose: Enacted to correct historical injustices faced by forest-dwelling communities deprived of traditional land and resource rights during colonial rule.
    • Core Objective: Ensures tenurial security, livelihood protection, and ecological stewardship of forest-dependent populations.
    • Beneficiaries: Covers Scheduled Tribes (STs) and Other Traditional Forest Dwellers (OTFDs) who have lived in and depended on forests for generations.
    • Scope: Recognises both individual and collective rights over forest land and produce, extending to cultivation, habitation, and minor forest produce use.
    • Governance Principle: Empowers Gram Sabhas as the central authority for recognising and managing forest rights, reinforcing local autonomy.
    • Integration Goal: Aligns forest governance with tribal self-rule, complementing the Panchayats (Extension to Scheduled Areas) Act, 1996 (PESA).

    Key Features of the FRA:

    • Individual & Community Rights: Legal recognition for occupation, cultivation, residence, and use/sale of minor forest produce.
    • Community Forest Resource (CFR) Rights: Grants Gram Sabhas control to protect, regenerate, and manage community forests.
    • Habitat Rights: Protects Particularly Vulnerable Tribal Groups (PVTGs) and pre-agricultural forest communities.
    • Governance Structure: Multi-level verification, Gram Sabha → Sub-Divisional Committee → District-Level Committee, for rights adjudication.
    • Development Provisions: Allows limited diversion of forest land for public utilities with Gram Sabha consent.
    • Eviction Safeguard: No eviction until claims are fully processed and rights recognised.
    • Decentralised Oversight: Empowers Gram Sabha as the final decision-making authority on forest rights and management.
    • Legal Integration: Reinforces PESA’s participatory governance and community-led conservation in Scheduled Areas.

  • Greenhouse Gas Emission Intensity (GEI) Target Rules, 2025

    Why in the News?

    The Centre has notified the first legally binding Greenhouse Gas Emission Intensity (GEI) Target Rules, 2025 for four high-emission sectors:  aluminium, cement, chlor-alkali, and pulp & paper.

    This marks a critical step in operationalising the Carbon Credit Trading Scheme (CCTS), 2023.

    Back2Basics: Greenhouse Gas Emission Intensity (GEI)

    • Overview: GEI is the amount of GHGs emitted per unit of product output or economic activity;  for example, the emissions released in producing one tonne of cement, aluminium, or steel.
    • Unit of Measurement: Expressed in tonnes of carbon dioxide equivalent (tCO₂e) per unit of product.
    • Composition:
      • Primary gases: Carbon dioxide (CO₂), Methane (CH₄), Nitrous oxide (N₂O).
      • Synthetic gases: Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), Sulphur hexafluoride (SF₆).
    • Purpose: GEI helps measure the efficiency of industrial production in terms of emissions.
    • Policy Significance: Reducing GEI aligns industrial operations with national and global climate commitments, particularly under the Paris Agreement (2015), where India has pledged to cut its emissions intensity of GDP by 45% by 2030 (from 2005 levels).

    About Greenhouse Gas Emission Intensity (GEI) Target Rules, 2025:

    • Notification: Issued by the MoEFCC on October 8, 2025, these are India’s first legally binding emission intensity targets for industries.
    • Objective: To limit greenhouse gas emissions per unit of product output in high-emission sectors, thereby promoting low-carbon industrial growth and aligning with India’s Paris Agreement commitment to reduce emission intensity of GDP by 45% by 2030 (from 2005 levels).
    • Coverage: Applies to 282 industrial units across four sectors– cement (186 units), aluminium (13), chlor-alkali (30), and pulp & paper (53).
    • Compliance Period: 2025–26 and 2026–27; emission limits expressed in tCO₂e (tonnes of CO₂ equivalent) per unit of product.
    • Mechanism:
      • Units achieving targets earn carbon credits (certified by the Bureau of Energy Efficiency).
      • Non-compliant units must buy credits or face environmental compensation under CPCB oversight.
    • Purpose: To operationalise India’s domestic carbon market, encourage technology upgrades, and institutionalise market-based climate compliance.
    • Outcome: Marks transition from voluntary energy-efficiency drives (PAT Scheme) to a legally enforceable carbon-intensity regime, integrating emission monitoring, trading, and compliance.

    What is the Carbon Credit Trading Scheme (CCTS), 2023?

    • Launched by: Ministry of Power in 2023 to establish a domestic carbon trading market under India’s Energy Conservation Act framework.
    • Objective: To create a structured mechanism for generating, certifying, and trading carbon credits earned through verified emission reductions.
    • Administered by: Bureau of Energy Efficiency (BEE), which issues Carbon Credit Certificates (CCC) to compliant industries.
    • Framework:
      • Industries meeting or exceeding GEI targets receive tradable credits.
      • Entities failing to meet targets must purchase credits to offset excess emissions.
      • Credits are traded on the Indian Carbon Market (ICM) platform.
    • Purpose: To make emission reduction economically incentivised, transforming carbon from a cost burden into a market asset.
    • Global Parallel: Similar to the EU Emissions Trading System (2005) and China’s National Carbon Market (2021).
    • Significance: Integrates energy efficiency, emission control, and fiscal instruments to drive India’s net-zero transition through a market-based, transparent, and measurable approach.

  • 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.
