  • How is the Aravalli range to be protected

    Introduction

    The Aravalli range, among the world’s oldest mountain systems, functions as a critical ecological barrier preventing desertification of the Indo-Gangetic plains. Stretching over 650 km from Gujarat to Delhi, the range plays a central role in climate moderation, groundwater recharge, and biodiversity conservation. However, decades of inconsistent definitions, regulatory violations, and mining pressures have degraded large tracts, necessitating renewed judicial intervention.

    Why in the News

    The Supreme Court, in a recent order, settled on a uniform definition of the Aravalli hills and ranges, paused the grant of fresh mining leases, and directed preparation of a Sustainable Mining Management Plan (SMMP). This marks a decisive shift from fragmented state-level interpretations that previously enabled unregulated mining. The intervention is significant as it directly addresses regulatory dilution, illegal extraction, and ecological degradation across Delhi-NCR, Haryana, Rajasthan, and Gujarat.

    Ecological and Strategic Significance of the Aravalli Range

    1. Ecological Barrier: Prevents eastward expansion of the Thar Desert into Haryana, Rajasthan, and western Uttar Pradesh.
    2. Climate Regulation: Supports regional climate stability and moderates extreme temperatures.
    3. Groundwater Recharge: Functions as a major recharge system for aquifers supplying urban and rural settlements.
    4. River Systems Support: Acts as a source region for rivers such as Chambal, Sabarmati, and Luni.
    5. Biodiversity Reservoir: Hosts diverse flora and fauna across forested and semi-arid ecosystems.
    6. Mineral Endowment: Contains limestone, marble, granite, zinc, copper, gold, and tungsten-driving extraction pressures.

    Historical Mining Pressure and Regulatory Failure

    1. Mining Legacy: Stone and sand mining persisted for decades due to mineral richness.
    2. Environmental Degradation: Caused air pollution, groundwater depletion, and ecosystem fragmentation.
    3. Legal Non-Compliance: Mining frequently operated without valid environmental clearances.
    4. International Commitments: Violates India’s obligations under the UN Convention to Combat Desertification.
    5. Judicial Trigger: Supreme Court intervention followed systemic regulatory failure at state levels.

    Early Executive and Judicial Interventions

    1. MoEF Restrictions (1990s): Issued mining restrictions across the Aravallis.
    2. Persistent Violations: State-level enforcement failures undermined restrictions.
    3. Supreme Court Ban (2009): Imposed a blanket ban on mining in Faridabad, Gurgaon, and Mewat.
    4. Fresh Mining Leases: Prohibited new leases and renewals pending comprehensive assessment.
    5. CEC Mandate: Central Empowered Committee tasked with examining mining impacts.

    Central Empowered Committee Findings and Recommendations

    1. Landscape-Level Assessment: Recommended macro-level environmental impact assessment.
    2. Mining Prohibition Zones: Advised bans in ecologically sensitive areas.
    3. Water Protection: Highlighted risks to recharge zones and water bodies.
    4. Strict Regulation: Suggested prohibition of mining until proper mapping and impact studies.
    5. Implementation Timeline: Recommendations placed before the Court after delayed compliance.

    Need for a Uniform Definition of the Aravallis

    1. State Inconsistencies: Different criteria used by states to identify Aravalli land.
    2. FSI Criteria (2010):
      1. Slope ≥ 3°
      2. Hill Height ≥ 100 m
      3. Valley Width ≥ 500 m
      4. Enclosed Area Criteria
    3. Regulatory Loopholes: Narrow definitions enabled mining below 100 m height.
    4. Scientific Objections: CEC flagged exclusion of slopes and foothills as ecologically flawed.
    5. Judicial Resolution: Supreme Court approved a nationally consistent definition.

    Supreme Court Directions on Mining Governance

    1. Sustainable Mining Management Plan: Directed preparation of SMMP for Aravalli-NCR.
    2. Absolute Prohibition: Banned mining in highly sensitive zones.
    3. Conditional Permissions: Allowed limited mining under strict regulatory oversight.
    4. Carrying Capacity Assessment: Mandated ecological thresholds before approvals.
    5. Restoration Measures: Required rehabilitation and restoration planning.

    Green Wall Project and Landscape Restoration

    1. Project Launch (June 2025): Centre initiated the Aravalli “Green Wall”.
    2. Geographic Scope: 5-km buffer across 29 districts in Gujarat, Rajasthan, Haryana, and Delhi.
    3. Restoration Target: 26 million hectares of degraded land by 2030.
    4. Climate Co-Benefits: Enhances carbon sequestration and desertification control.
    5. Policy Integration: Aligns with land degradation neutrality goals.

    Why Mining Has Not Been Completely Banned

    1. Past Experience: Total bans encouraged illegal syndicates and violent extraction.
    2. Regulatory Vacuum: Blanket prohibitions weakened oversight mechanisms.
    3. Calibrated Approach:
      1. Existing legal mines regulated stringently.
      2. Ecologically sensitive zones declared no-go areas.
    4. Governance Focus: Emphasis on enforceable regulation rather than prohibition.

    Conclusion:

    Protecting the Aravalli range is essential not only for conserving an ancient geomorphic system but also for safeguarding north India from accelerating desertification, groundwater decline, and ecological instability. The Supreme Court’s insistence on a uniform definition, regulated mining, and landscape restoration marks a shift from fragmented governance to science-based environmental stewardship.

  • The future of governance in post-Maoist India

    Introduction

    The Maoist movement in India emerged and expanded not merely as an armed insurgency but as a response to prolonged governance failure in Fifth Schedule areas. Administrative neglect, weak service delivery, erosion of tribal self-governance, and systematic alienation from land and forests created conditions for parallel Maoist authority structures. While security operations have weakened Maoist violence, the deeper governance paradoxes of the Fifth Schedule administration remain unresolved, threatening durable peace and democratic legitimacy.

    Why in the News

    The article gains relevance as India enters a post-Maoist phase in several Fifth Schedule districts following sustained security operations. While insurgent violence has declined sharply since the peak of the 1990s and early 2000s, governance outcomes in these regions remain weak. Planning Commission’s Expert Group (2008) recorded that regions with abundant natural resources were reduced to “penury due to state neglect and poor governance.” Despite constitutional safeguards, tribal areas continue to face under-representation, diluted self-rule, and extractive development. The contrast between declining insurgency and persistent governance failure marks a critical inflection point in India’s internal security and federal governance trajectory.

    Evolution of Maoism as a Governance Phenomenon

    1. Administrative Neglect: Enabled Maoist penetration by leaving large governance vacuums in health, education, policing, and justice delivery.
    2. Parallel Authority Structures: Maoists provided dispute resolution, welfare access, food rations, and swift justice through kangaroo courts.
    3. Political Mobilisation: Insurgency functioned as a vehicle for tribal assertion against state institutions perceived as extractive.

    Constitutional Vision of the Fifth Schedule

    1. Protective Framework: Designed as a socio-political contract recognising distinct tribal histories and vulnerabilities.
    2. Institutional Architecture: Tribal Advisory Councils, Governor’s special powers, and restrictions on land alienation.
    3. Developmental Autonomy: Emphasised governance aligned with tribal customs, livelihoods, and cultural preservation.

    Structural Failures in Fifth Schedule Governance

    1. Under-Representation of Adivasis: Locals largely excluded from bureaucracy, policing, and revenue administration.
    2. Administrative Alienation: Officials lacked cultural familiarity and sensitivity to tribal social structures.
    3. Weak Institutional Capacity: Fifth Schedule provisions remained procedural rather than transformative.

    Land, Forests, and the Crisis of Resource Governance

    1. Land Alienation: Millions dispossessed despite constitutional safeguards and land acquisition laws.
    2. Revenue Administration Abuse: Land acquisition and forest governance emerged as the most violated provisions.
    3. Extractive Development Model: Mineral-rich regions experienced development without local benefit-sharing.

    Failure of Decentralised Self-Governance Mechanisms

    1. PESA Dilution: Panchayat Extension to Scheduled Areas Act remained poorly implemented and routinely violated.
    2. Gram Sabha Marginalisation: Consent provisions ignored in mining, land acquisition, and forest diversion.
    3. State Resistance: Amendments and administrative practices diluted original intent of self-rule.

    Contradictions in Rights-Based Legislation

    1. Forest Rights Act (FRA): Provided legal protection but faced bureaucratic resistance and weak enforcement.
    2. CAF Act, 2016: Prioritised compensatory afforestation over livelihood and habitation rights.
    3. Legal Dilution: Judicial and executive interventions weakened protective intent of tribal legislation.

    Governance Improvements and Their Limits

    1. Service Delivery Gains: Improved access to roads, telecom, welfare schemes, and digital payments.
    2. Digital Governance: Cash transfers and e-governance reduced some leakages.
    3. Persistent Institutional Weakness: Education, policing, health, judiciary, and revenue administration remain inadequate.

    Post-Maoist Governance Challenge

    1. Leadership Vacuum: Absence of credible tribal leadership in governance institutions.
    2. Performance Deficit: Panchayats in Fifth Schedule areas underperform compared to Sixth Schedule autonomous councils.
    3. Trust Deficit: Continued alienation risks ideological re-radicalisation despite reduced violence.

    Way Forward

    1. Fifth Schedule Reorientation: Ensures faithful implementation of constitutional safeguards by operationalising the Governor’s special responsibilities, strengthening Tribal Advisory Councils, and limiting routine administrative overrides.
    2. PESA-Centred Decentralisation: Restores primacy of Gram Sabhas in land acquisition, mining approvals, forest governance, and welfare delivery to re-establish democratic legitimacy at the grassroots.
    3. Rights-Based Resource Governance: Enforces Forest Rights Act provisions in letter and spirit, integrates livelihood security with conservation, and curbs extractive practices that marginalise tribal communities.
    4. Administrative Inclusion: Expands recruitment, posting, and capacity-building of local tribal personnel in policing, revenue administration, and service delivery institutions.
    5. Development-Security Convergence: Aligns security operations with civil administration through coordinated district.

    Conclusion

    The retreat of Maoist violence in large parts of India marks a significant security achievement, but it does not signify the resolution of the deeper governance crisis that gave rise to Left Wing Extremism. Persistent administrative under-representation of adivasis, dilution of Fifth Schedule protections, weak implementation of PESA and forest rights, and extractive resource governance continue to erode state legitimacy in these regions. Without restoring genuine tribal self-governance, strengthening local institutions, and aligning development with constitutional intent, the post-Maoist phase risks becoming a period of fragile stability rather than durable peace. Sustainable normalcy in Fifth Schedule areas ultimately depends on governance reform, not security dominance alone.

    PYQ Relevance

  • Climate change, deforestation worsened impact of SE Asia cyclones

    Introduction

    Rising global temperatures, deforestation, and rapid urbanisation have significantly intensified the flood impacts of tropical cyclones across Sri Lanka, Malaysia, Indonesia, and Thailand. Recent cyclones such as Dithawru and Senyar produced rainfall and flooding far exceeding historical norms, marking a shift from cyclical monsoon flooding to extreme, compound climate disasters.

    Why in the News

    A new attribution study by the World Weather Attribution (WWA) group establishes that climate change, land-use change, and urban expansion together amplified cyclone-induced floods in Southeast Asia to unprecedented levels. Cyclone Senyar made landfall in Indonesia and Malaysia on November 26-27, while Dithawru struck Sri Lanka earlier in November, causing extensive damage and over 1,600 deaths. The study highlights rainfall intensities rising up to 160% in Sri Lanka and 50% in Malaysia compared to pre-industrial baselines, underscoring a structural climate shift rather than isolated weather anomalies.

    Escalating Cyclone Rainfall in a Warming Climate

    1. Global Temperature Rise: Increases atmospheric moisture-holding capacity as temperatures have risen by 1.3°C since the mid-1800s.
    2. Moisture Amplification: Each 1°C rise enables the atmosphere to hold 7% more moisture, intensifying rainfall.
    3. Cyclone Energy Supply: Elevated sea surface temperatures in the North Indian Ocean provided additional latent heat for cyclone formation.
    4. Rainfall Extremes: Five-day rainfall events in Sri Lanka intensified by 160%, while extreme rainfall in Malaysia increased by 50%.

    Sea Surface Temperature Anomalies and Storm Intensification

    1. Above-Normal SSTs: Sea surface temperatures during Cyclone Senyar were 0.2°C higher than the 1991-2020 average.
    2. Storm Development: Warmer oceans increased evaporation rates, strengthening storm systems and prolonging rainfall duration.
    3. Frequency Shift: The study identifies a rise in extreme rainfall frequency rather than mere intensity spikes.

    Deforestation as a Flood Multiplier

    1. Forest Cover Decline: Sri Lanka lost 90% of forest cover between 1900 and 2020.
    2. Hydrological Impact: Reduced infiltration and increased surface runoff amplified landslides and flash floods.
    3. Human Impact: Rainfall-induced landslides in Sri Lanka caused over 600 deaths.
    4. Indonesia Case: Nearly 25% of old-growth forests on palm oil plantations were cleared between 1991 and 2020, reducing natural flood buffers.

    Rapid Urbanisation and Exposure Expansion

    1. Population Exposure: Rising numbers of people reside in high-intensity flood-risk zones across Sri Lanka and Indonesia.
    2. Infrastructure Stress: Roads, railways, and cropland expansion increased surface sealing and runoff velocity.
    3. Flood Pathways: Inadequate drainage and altered land gradients intensified urban flooding during Cyclone Senyar.

    Flood Impacts Beyond Rainfall

    1. Economic Losses: Sustained economic losses estimated between $6-7 billion, equivalent to 3-5% of GDP in affected regions.
    2. Agricultural Damage: More than 137,000 acres of agricultural land damaged due to floods and infrastructure failures.
    3. Secondary Hazards: Flooding triggered dam breaches, canal destruction, and landslides, compounding disaster severity.

    Attribution Science and Policy Significance

    1. Event Attribution: Confirms climate change as a decisive factor in amplifying rainfall and flood impacts.
    2. Shift in Disaster Pattern: Floods no longer limited to monsoon cycles but increasingly driven by short-duration extreme events.
    3. Policy Gap: Highlights inadequate land-use planning and ecosystem protection in climate adaptation strategies.

    Conclusion

    The study establishes that cyclone disasters in Southeast Asia are no longer episodic weather events but outcomes of sustained climate warming, ecological degradation, and unplanned urban growth. Addressing future flood risks requires integrating climate mitigation, forest conservation, and land-use planning into disaster governance frameworks.

    PYQ Relevance

    [UPSC 2023] The Intergovernmental Panel on Climate Change (IPCC) has predicted a global sea level rise of about one metre by AD 2100. What would be its impact in India and the other countries in the Indian Ocean region? 

    Linkage: The article reinforces IPCC projections by showing how warming oceans and climate change amplify coastal flooding risks in the Indian Ocean region. Sea-level rise acts as a risk multiplier, intensifying cyclone impacts, floods, and ecosystem loss in India and neighbouring countries.
