Current Affairs – April 25, 2026

{GS1 – Geo} Hanging Glaciers Emerging as a Major Himalayan Hazard

• Context (TH): A recent study has identified 219 unstable hanging glaciers in the Alaknanda Basin, highlighting the rising risk of glacier-related hazards in the Himalayan region.

Risks Posed by Hanging Glaciers

• High Instability: Nearly 1/3 of the glaciers in the Alaknanda basin are highly unstable and prone to sudden breakoffs and avalanches.
• Cascading Disasters: Collapses can block rivers, form temporary lakes & trigger downstream flash floods.
• Impact Potential: Stored ice and water volumes can cause widespread destruction, as seen in the 2021 Chamoli disaster.
• Rapid Urbanisations: Urban growth in high-altitude areas (e.g., Badrinath–Mana stretch) increases exposure to glacier-related hazards.

Climatic and Geological Drivers of Glacier Instability

• Accelerated Warming: The Himalayas are warming faster (nearly thrice) than the global average, increasing glacier melt and instability.
• Temperature Variability: Rapid freeze–thaw cycles weaken glacier structure. Himalayan glaciers are thinning at 0.3–1 m/year, faster than global averages.
• Changing Precipitation: Shifts in snowfall and rainfall patterns alter glacier mass balance and stability.
• Permafrost Degradation: Thawing of frozen ground reduces slope stability and increases the risk of glacier detachment.
• High Seismicity: Earthquakes and tectonic activity in the Himalayas can trigger collapse and avalanches.

Strategies to Mitigate Risks from Hanging Glaciers

• Targeted Monitoring: Map and track high-risk glaciers using satellite, LiDAR, and ground sensors (like in the Alps).
• Early Warning Systems: Install real-time avalanche/flood alerts in vulnerable zones (e.g., Badrinath–Mana stretch along NH-7).
• Land-Use Regulation: Declare hazard-prone areas as restricted zones, as glacial exposure is rising due to rapid urbanisation.
• Climate Adaptation Planning: Integrate glacier risks into disaster frameworks (similar to NDMA guidelines on GLOF), learning from events like the 2021 Chamoli disaster.
• Capacity Building: Train local administration, BRO, SDRF, and communities in high-altitude disaster response and rescue operations.

{GS2 – Polity} Delhi HC Stresses Objective Review in Premature Release Cases

• Context (IE | TOI): Delhi High Court has questioned the denial of premature release of the convict in the Priyadarshini Mattoo case.

Background of the Case

• DU student Priyadarshini Mattoo was raped and murdered by Santosh Kumar Singh in Delhi in 1996.
• Trial: The trial court acquitted the accused in 1999, but the Delhi HC convicted him in 2006 and awarded the death penalty.
• Sentence Commuted: The Supreme Court commuted the sentence to life imprisonment in 2010.
• Current Issue: After nearly 30 years in custody, his plea for premature release was rejected twice by the Sentencing Review Board.

About Premature Release

• Early release of life convicts based on reformation, good conduct, and reduced threat to society.
• Legal Basis: Derived from Articles 72 & 161 of the Constitution and provisions under Bharatiya Nagarik Suraksha Sanhita (S.473, S.474 & S.475).
• Minimum Eligibility: Requires at least 14 years of actual imprisonment (mandatory for serious offences).
• Not Automatic: Eligibility does not guarantee release; each case is assessed individually.

About Sentencing Review Board (SRB)

• SRB is a state-level administrative body that reviews cases of premature release (remission) of life convicts.
• Composition: Includes senior officials such as DG Prisons, Police Commissioner, Home Department officials, and Chief Secretary.
• Function: Examines the eligibility of convicts & recommends release or rejection to the state government.
• Criteria of Release: Conduct and behaviour in jail, compliance with parole/bail conditions, risk to society, and rehabilitation prospects.
• Limitations: Recommendations are not final; the government takes the final decision.

Observations by the Delhi High Court

• Public Perception Bias: Court stated SRB decisions appear influenced by the unpopularity of the convict rather than by objective criteria.
• Reformation Principle: Emphasised that long incarceration and signs of reform must be considered.
• Heinousness Not Sole Factor: Severity of crime alone cannot justify continued denial of remission.
• Objective Justice: Courts stressed decisions must be based on law, not emotions or societal pressure.

{GS2 – Governance} Decline of Trade Unions in India

• Context (TH): Recent worker protests over wages and social security have revived debate on weakening trade unions and their declining role in protecting labour rights.

Extent of De-Unionisation in India

• Low Unionisation: Only about 6.3% of the workforce is unionised, with just 1.8% in the private sector, showing weak coverage.
• Informal Employment: Rapid growth of informal (~90%) and contract labour has reduced union reach and membership.
• Decline in Public Sector: LPG reforms led to privatisation, downsizing of PSUs and public-sector jobs (19.6 million in 1991 to 17.5 million in 2008), weakening traditional union strongholds.
• Restrictive Legal Framework: The Industrial Relations Code, 2020, requires a 10% workforce for union formation, limiting the formation of new unions.

Role of Trade Unions

• Collective Bargaining: Represent workers in negotiating wages, working conditions, and job security with employers.
• Policy Participation: Engage in tripartite mechanisms (government–employer–union) for minimum wage fixation and labour reforms.
• Worker Protection: Advocate for social security, labour rights, and welfare measures (e.g. Noida unrest), especially for vulnerable workers.
• Representation: Organise protests & movements to voice worker grievances& influence policy decisions.

Measures to Strengthen Trade Unions

• Expand Coverage: It includes contract, gig, and informal workers within union frameworks to reflect changing labour market realities.
• Strengthen Labour Laws: Ensure effective enforcement of minimum wages, social security, and worker protection laws.
• Improve Collective Bargaining: Empower unions through stronger tripartite institutions and negotiation mechanisms (ratify the ILO Convention on Collective Bargaining).
• Labour-Intensive Growth: Boost manufacturing (PLI scheme) and formal job creation (Employment Linked Incentive Scheme) to reduce informality and enhance union relevance.

{GS3 – Envi} Plant Forests to Restore Biodiversity for the Future

• Context (DTE): Global tree-planting efforts risk ecological failure as scientists warn monocultures cannot restore biodiversity, urging a shift toward resilient mixed forests.

Issues With Plantation Efforts Worldwide

• Flawed Restoration Model: Global initiatives focus on planting billions of trees, but often ignore ecosystem quality, leading to poor survival and weak outcomes.
• Monoculture Risk: Single-species plantations create fragile ecosystems (“green deserts”) highly vulnerable to pests, drought, and fires.
• High Failure Evidence: Large plantation drives can fail massively, as seen in Turkey, where ~90% of 11 million saplings died within months.

Ecological and Economic Benefits of Mixed-Species Forests

• Higher Productivity: Mixed forests show up to ~80% greater tree growth than monocultures, increasing overall biomass and yield.
• Enhanced Biodiversity: Support 50% more insects, birds, and plant species, creating richer and more stable ecosystems.
• Greater Climate Resilience: Diverse species improve resistance to droughts, pests, and diseases, reducing the risk of large-scale failure (e.g., ~90% sapling loss in Turkey in monoculture).
• Improved Carbon Sequestration: Mixed forests store more carbon over time, making them more effective for climate change mitigation.
• Better Soil & Water Health: Diverse root systems enhance soil fertility, nutrient cycling, and water retention, sustaining long-term productivity.

Measures to Build Resilient Forests for the Future

• Shift to Mixed Plantations: Promote multi-species forests (BiodiversiTREE shows up to 80% higher growth and richer biodiversity).
• Focus on Ecosystem Restoration: Align with UN Decade on Ecosystem Restoration by restoring full ecosystems (soil, water, wildlife), not just planting trees.
• Use Native Species: Prioritise local species to improve survival; monoculture failures highlight the risks of poor species selection.
• Align Policy & Incentives: Redirect funding from monocultures to biodiversity-rich models; global efforts like the Trillion Trees Campaign need to prioritise quality forests over quantity targets.

{GS3 – Envi} Methane Emissions from Landfills

• Context (DTE): A satellite-based study highlights India’s major landfill sites as significant contributors to global methane emissions.

Findings of the Methane Emissions Study

• Global Hotspots: Chile and Brazil have the highest number of top landfill methane emitters, followed by India and Saudi Arabia.
• Emitters in India: Landfills in Secunderabad (Telangana) and Mumbai are among the world’s top 25 methane-emitting sites in 2025.
• Emission Intensity: Top sites emit ~3.6–7.5 tonnes of methane per hour, far above typical landfill emissions.
• Extreme Indian Case: Delhi’s Ghazipur landfill earlier recorded a 400-tonne/hour “super-emitter” event.

Why Landfills Emit Methane?

• Anaerobic Decomposition: Organic waste (food, paper, garden waste) breaks down in the absence of oxygen, producing methane.
• Poor Segregation: Mixed waste increases untreated organic matter in landfills.
• Low Processing: India generates around 62 million tonnes of solid waste annually, but only 30–35% is processed.
• Weak Landfill Management: Lack of composting, biomethanation and gas capture allows uncontrolled emissions.
• Long-Term Dumping: Continuous waste accumulation makes landfills persistent methane sources.
