Expansion of Lok Sabha Seats: Proposal for Inclusive Representation

Why in News

• The Government is considering expanding the Lok Sabha to implement women’s reservation, while maintaining the current state-wise representation balance.

Proposed Changes in Lok Sabha

1. Increase in Strength

• Current Strength: 543 members
• Proposed Expansion: Around 816 members
• Aim: To accommodate reservation without disturbing existing representation patterns.

2. Women’s Reservation

• Around 273 seats (one-third) proposed to be reserved for women.
• Linked to the 106th Constitutional Amendment Act, 2023.

3. Implementation Timeline

• Likely to be operational from the 2029 General Elections.

4. Delinking from Delimitation

• Proposal to separate women’s reservation from Census and delimitation processes, enabling faster implementation.

5. State-wise Seat Distribution

• Initial expansion to retain current proportional representation of states, avoiding immediate political imbalance.

Implications of Lok Sabha Expansion

1. Enhanced Representation

• Larger House size would Improve population representation and Strengthen regional inclusivity

2. Boost to Women’s Participation

• 33% reservation will significantly increase women’s presence in legislative decision-making.

3. Advantage to Larger States

• States such as Uttar Pradesh, Maharashtra, Bihar likely to gain more seats due to their higher population share.

4. Political Realignment

• Expansion may reshape Electoral strategies, Party dominance, Coalition dynamics
• Larger states may gain greater political influence.

Key Concerns and Challenges

1. Federal Imbalance

• Future delimitation could favour high-population northern states, leading to tensions with southern states.

2. Delimitation Uncertainty

• Use of 2011 Census data may not reflect current demographic realities.
• Risk of political disputes over seat allocation.

3. Constitutional Validity of Delinking

• Separating women’s reservation from delimitation may raise legal and constitutional concerns.

4. Governance Efficiency

• A significantly larger House (816 MPs) could complicate parliamentary proceedings and affect decision-making efficiency

Constitutional Amendments Required

1. Amendment to Article 81

• To increase the total strength of the Lok Sabha beyond current limits.

2. Amendment to Article 82

• To allow early delimitation based on available Census data.

3. Role of 106th Constitutional Amendment Act, 2023

• Provides for women’s reservation in Lok Sabha and State Assemblies.
• May require modification to enable delinking from delimitation.

4. Parliamentary Approval

• Requires a special majority: Two-thirds of members present and voting & Absolute majority of total membership

Ethanol Blending in Petrol: Advancing India’s Energy Transition

Why in News

• Recent disruptions in global oil supply chains have underscored the need for India to accelerate ethanol blending to reduce import dependence and strengthen energy security.
• The situation mirrors global precedents such as Brazil’s response to the 1970s oil crisis.

Global Best Practice: Brazil’s Ethanol Model

1. Proálcool Programme (1975)

• Launched by Brazil after the 1973 oil crisis to reduce reliance on crude oil.

2. Key Features

• Policy Support: Subsidies, assured pricing, and mandatory blending (~30%)
• Flex-Fuel Vehicles: Vehicles capable of running on petrol, ethanol, or both
• Integrated Ecosystem: Strong linkage between Sugarcane production, Ethanol supply chain, Fuel distribution infrastructure

Status of Ethanol Blending in India

1. Ethanol Blended Petrol (EBP) Programme

• Launched in 2003 to promote blending of ethanol with petrol.
• Accelerated under the National Policy on Biofuels.

2. Blending Achievement

• India has achieved 20% ethanol blending (E20) in 2025, ahead of the original 2030 target.

3. Economic Gains

• Estimated savings of around ₹1.04 lakh crore in foreign exchange due to reduced crude imports.

4. Infrastructure Expansion

• Over 700+ distilleries with a combined capacity of ~1,700 crore litres.
• Growth supported by government-backed loans and policy incentives.

Understanding Ethanol

1. Basic Characteristics

• Chemical formula: C₂H₅OH
• A renewable biofuel derived from crops like Sugarcane, Maize, Wheat

2. Production Methods

4. Environmental Advantages

• Leads to 15–20% lower CO₂ emissions compared to conventional fuels.
• Improves air quality and reduces carbon footprint.

Key Challenges

1. Food vs Fuel Debate

• Use of food grains like rice and maize raises concerns about food security and price inflation.

2. Water Stress

• Sugarcane cultivation requires 2000–3000 litres of water per kg, straining water resources in regions like Maharashtra.

3. Feedstock Constraints

• Ethanol production depends on agricultural output, which is vulnerable to Monsoon variability and Climate change

4. Vehicle Compatibility

• Higher blends (E20+) may Reduce efficiency in older vehicles and require engine modifications

5. Infrastructure Gaps

• Inadequate Ethanol pipelines, Storage facilities, Blending depots, especially in rural areas

Global Assessment of Migratory Freshwater Fishes: Alarming Biodiversity Decline

Why in News

• The Global Assessment of Migratory Freshwater Fishes Report was released at COP15 of the Convention on the Conservation of Migratory Species.

About the Convention on Migratory Species (CMS)

• Also known as the Bonn Convention.
• A UNEP-backed intergovernmental treaty that provides a global framework for Conservation of migratory species and Protection of their habitats
• Facilitates international cooperation for species that cross national boundaries.

Key Findings of the Report

1. Severe Population Decline

• Global populations of migratory freshwater fish have declined by 81% since 1970.

2. Collapse of Megafish Species

• Large species (“megafish” weighing over 30 kg) have declined by 94%, indicating ecosystem stress.

3. Highly Threatened Taxa

• Sturgeons and paddlefishes are identified as the most threatened vertebrate group globally.

4. CMS-Listed Species at Risk

• Nearly 97% of migratory fish species listed under CMS face extinction threats.

5. Gap in Protection

• Report identifies 325 additional species requiring international protection.
• However, only 24 species are currently listed, highlighting a major conservation gap.

6. Regional Vulnerability

• Asia has the highest number of at-risk species (205 species), followed by South America, Europe, Africa, North America

7. Major Threat Drivers

• Construction of dams disrupting migration routes
• Habitat degradation and floodplain loss
• Overfishing
• Pollution from agricultural and industrial runoff

Key Recommendations

1. “Swimways” Concept

• Establish protected migratory corridors for fish, similar to bird flyways.
• Ensures safe passage across river systems and international boundaries.

2. Institutional Coordination

• Calls for stronger synergy between Convention on the Conservation of Migratory Species and Convention on Biological Diversity
• Aim: To enhance global conservation outcomes.

India-Specific Findings

• High-Priority River Basin: Ganga–Brahmaputra–Meghna river system identified as a critical hotspot due to high migratory biomass.

• Excessive extraction lowers water tables, increasing concentration of geogenic toxins.

2. Agricultural Runoff:

• Overuse of fertilisers and pesticides leads to Nitrate leaching into groundwater & Long-term soil and water degradation

3. Sewage and Sanitation Issues:

• Nearly 70% of urban sewage remains untreated.
• Contaminants seep into shallow aquifers, spreading pathogens and nitrates.

4. Industrial Pollution:

• Discharge of untreated effluents introduces toxic heavy metals such as Lead, Cadmium, Chromium

Key Impacts of Contamination

1. Health Crisis

• Leads to severe diseases such as Fluorosis, Arsenicosis, Neurological disorders
• Disproportionately affects children and vulnerable populations.

2. Economic Consequences

• According to the World Bank, Water-related issues could reduce India’s GDP by ~6% by 2050.

3. Educational Impact

• Chronic illnesses result in Increased absenteeism and Impaired cognitive development
• Highly affected regions include Assam and Bihar.

4. Ecological Damage

• Contaminated water used for irrigation Degrades soil fertility, Introduces toxins into crops, Disrupts aquatic ecosystems and food chains
