Current Affairs – March 29, 2026

{GS2 – Polity} Expansion of Lok Sabha Seats

Context (IE): The government is considering expanding the Lok Sabha to implement women’s reservation while maintaining current state-wise representation.

Proposed Changes in Lok Sabha

Increase in Lok Sabha Size: Proposal to expand Lok Sabha from 543 to 816 members.
Women’s Reservation: Around 273 seats (1/3rd) to be reserved for women.
Implementation Timeline: Likely to come into effect from the 2029 Lok Sabha elections.
Delinking from Delimitation: Plan to separate women’s reservation from Census & delimitation process.
State Ratios: Seats to be increased while keeping existing state-wise proportions unchanged initially.

Impact of Lok Sabha Expansion

Enhanced Representation: More seats will improve representation of the population and regions, making Parliament more inclusive.
Women’s Political Participation: 33% reservation (273 seats) will significantly increase women’s representation in Parliament.
Benefit to Larger States: States like Uttar Pradesh, Maharashtra, and Bihar will gain more seats due to a higher population share.
Political Realignment: This could transform electoral strategies, party representation, and coalition dynamics, as larger states gain substantial seat increases, while smaller states see only a slight increase.

Key Issues

Federal Imbalance: Future delimitation may favour high-population northern states, creating tensions with southern states over representation.
Delimitation Uncertainty: Using 2011 Census data may not reflect current population realities, leading to political disputes.
Women’s Reservation: Delinking from delimitation may raise legal and constitutional questions.
Governance Efficiency: A larger House (816 MPs) may create challenges in parliamentary functioning and decision-making efficiency.

Amendments Required to Implement these Changes

Article 81: To increase the Lok Sabha strength beyond the current constitutional limit.
Article 82: To enable early delimitation (based on 2011 Census) for redistribution of parliamentary seats.
106^th Constitutional Amendment Act, 2023: To delink women’s reservation from Census and delimitation and extend it to Lok Sabha and State Assemblies.
Parliamentary Majority: All constitutional amendments require special majority (2/3^rd of members present and absolute majority of total strength).

{GS2 – MoPNG} Ethanol Blending in Petrol

Context (IE): The disruption in oil supplies has highlighted India’s need to accelerate ethanol blending to reduce import dependence and enhance energy security.

Crisis offers an opportunity to restructure energy policy, like Brazil’s response after the 1970s oil shocks.

Proálcool Programme of Brazil

After the 1973 oil crisis, Brazil launched the Proálcool Programme (1975) to reduce oil import dependence through ethanol.
Government ensured subsidies, pricing support, & mandatory blending (30%) to promote ethanol use.
Adoption of flex-fuel vehicles (FFVs) enabled the use of petrol, ethanol, or both, increasing flexibility.
Developed a robust system linking sugarcane production, ethanol supply chain, & fuel infrastructure.

Status of Ethanol Blending in India

Ethanol Blended Petrol (EBP) Programme: Launched in 2003 to promote ethanol blending with petrol.
India has achieved 20% ethanol blending in petrol (E20) in 2025; advanced from 2030 under the National Policy on Biofuels.
Economic Impact: Ethanol blending has saved India ₹1.04 lakh crore in foreign exchange (crude imports).
Infrastructure: Over 700+ distilleries with a combined capacity of ~1,700 crore litres; significantly expanded through government-backed loans and licensing under the EBP Programme.

Ethanol (C₂H₅OH) is a renewable biofuel produced from crops like sugarcane, maize, and wheat.
Produced via fermentation of sugars by yeast or through ethylene hydration (petrochemical process).
Types of Ethanol: Includes 1^st Generation (food crops), 2G (agri-residues), 3G (algae), and 4G (engineered biomass).

Significance of Ethanol for India

Reduces Imports: India imports ~88% of its crude oil. E20 has already helped reduce imports of ~4–5 crore barrels of crude, saving foreign exchange.
Energy Security: Domestic ethanol acts as an alternative fuel buffer during supply disruptions.
Supports Farmers: Ethanol production uses sugarcane, maize, and surplus food grains, providing farmers with additional income streams.
Environmental Benefits: Ethanol blending reduces greenhouse gas emissions (≈15–20% lower CO₂ emissions) and improves air quality.

Issues with Ethanol Blending

Food-Fuel Conflict: Use of food grains like rice and maize raises concerns about food security.
Water-Intensive Crops: Sugarcane consumes ~2000–3000 litres of water per kg, stressing water-scarce regions like Maharashtra.
Limited Feedstock: Ethanol supply depends on agricultural output, which fluctuates due to monsoon variability and climate change.
Vehicle Compatibility: E20 or more fuel may cause efficiency loss in older vehicles designed for E10.
Logistics Lag: Ethanol pipelines, storage, and rural blending depots remain inadequate.

{GS3 – Envi} Global Assessment of Migratory Freshwater Fishes Report

Context (DTE): COP15 of the Convention on the Conservation of Migratory Species (CMS) released the Global Assessment of Migratory Freshwater Fishes report.

COP15: The 15^th meeting of the Conference of the Parties (COP15) to the CMS is being held in Campo Grande, Brazil, under the theme “Connecting Nature to Sustain Life“.

The Convention on Migratory Species (CMS), or Bonn Convention, is a UNEP-backed intergovernmental treaty that provides a global platform for conserving migratory species and their habitats.

Key Findings of the Report

Population Decline: Global populations of migratory freshwater fish have declined by 81% since 1970.
- Megafish Decline: “Megafish” species weighing over 30 kg have declined by 94%.
Most Threatened: Sturgeons and paddlefishes remain the most threatened vertebrate group.
CMS-Listed Species: Nearly 97% of migratory fish species currently listed under the CMS are threatened with extinction.
Unlisted Species: The report identifies 325 additional species eligible for international protection under CMS. Only 24 species are currently listed.
- Regional Risk: Asia has the highest number of at-risk species at 205, followed by South America, Europe, Africa, and North America.
Primary Threats: Dams, habitat degradation, loss of floodplains, overfishing, and runoff pollution.
Recommendations: The assessment calls for “Swimways“ (protected migratory corridors modelled after avian flyways) and stronger coordination between CMS and the Convention on Biological Diversity (CBD).

India-Specific Findings

Priority Basin: Ganga-Brahmaputra-Meghna river system was identified as a high-priority region due to its ‘high biomass of migrants.’
Flagship Species: Hilsa, Golden Mahseer, Goonch Catfish, and Indian Mottled Eel.
Endemism: India has the highest share of endemic freshwater finfish species in Asia at 27.8%.

{GS3 – Envi} India’s Growing Groundwater Contamination Crisis **

Context (LM): Union Government commissioned a project to assess fluoride removal technologies across drinking water systems amid rising groundwater contamination reports.

Current State of Groundwater Contamination & Safe Drinking Water

Contaminants: Nitrate, fluoride, arsenic, salinity, uranium, lead, and other heavy metals are the major contaminants; nitrate exceeds limits in nearly 20% of samples. [CGWB 2024 Report]
Hotspots: Arsenic contamination is concentrated in the Ganga-Brahmaputra basin, while fluoride is widespread across arid and semi-arid states such as Rajasthan and Gujarat.
Key Impact: Unsafe drinking water causes about two lakh deaths annually in India [NITI Aayog].
Access Gap: Jal Jeevan Mission (JJM) has provided tap connections to 81.6% of rural households, but only 76% of tested samples met quality standards.

Major Causes of Groundwater Contamination in India

Over-Extraction: India uses over 25% of global groundwater, depleting water tables and increasing geogenic toxins.
Agricultural runoff: Excessive fertiliser and pesticide use causes nitrate leaching into aquifers.
Sewage & Sanitation: Almost 70% of urban sewage remains untreated, enabling pathogens and nitrates to seep into shallow aquifers.
Industrial Effluents: Industrial clusters discharge untreated waste, releasing heavy metals like lead, cadmium, and chromium into groundwater systems.

Key Impacts of Groundwater Contamination

Health Crisis: Includes fluorosis, arsenicosis, and neurological damage, severely impacting children and vulnerable populations in contaminated areas.
Economic Burden: World Bank estimates that water contamination and scarcity could decrease India’s GDP by ~6% by 2050.
Educational Impact: Chronic illness increases absenteeism and hampers cognitive growth, especially in highly affected areas like Assam and Bihar.
Ecological Impact: Toxic irrigation reduces soil fertility and transfers pollutants to crops and water ecosystems, entering the food chain.

Recent Government Interventions

Jal Seva Aankalan: Launched in 2025, focuses on village-level service delivery assessments to identify gaps in water quality and regularity.
National Aquifer Mapping Programme: Maps aquifers to identify zones of availability and contamination for targeted intervention.
Ministry of Jal Shakti: Established over 2,840 laboratories and trained 24.8 lakh women to use Field Testing Kits for community-level water quality monitoring.
