[Bill 1: Lok Sabha & State Assemblies]             [Bill 2: Local Bodies (Panchayats/Municipalities)]
• Amends Art. 83 (Duration of Houses)              • Amends Art. 243K & 243ZA
• Amends Art. 172 (Duration of State Leg.)         • Synchronizes local body polls within 100 days
• Passed under Art. 368(2) (Special Majority)       • Requires Ratification by ≥ 50% of States
• Introduces "Appointed Date" & Unexpired Term      • Mandates Single Electoral Roll (ECI + SECs)

1. Duration of Houses (Articles 83 and 172):
   Introduction of an “Appointed Date” following a general election. If an Assembly is dissolved prematurely due to a no-confidence motion or hung assembly, the newly elected Assembly will serve only for the unexpired portion of the full five-year term, preventing asynchronous cycles.
2. Unified Electoral Roll (Article 325 amendment):
   Empowers the Election Commission of India (ECI) to build a unified single voter list in coordination with State Election Commissions (SECs), eliminating duplicate registries.
3. Ratification Nuance:
   While amending Assembly durations does not strictly alter federal distribution of powers under the proviso to Article 368(2), synchronizing local bodies (Part IX and IX-A) falls within the State domain and requires ratification by at least half of the State Legislatures.

Arguments For vs. Against

Key Recommendations & Way Forward

• Constructive Vote of No-Confidence: Incorporate the German constitutional model, where a motion of no-confidence must be paired with an affirmative vote for a named alternate leader, preventing frivolous premature dissolutions.
• Logistical Scaling: Phased ramp-up of secure manufacturing capacities for dual-purpose EVM/VVPAT units through BEL and ECIL.
• Broad-Based Political Consensus: Ensuring all regional stakeholders are consulted before tabling the bills in Parliament.

                                                      Energy Conservation Act

1. Target Identification: Phased carbon intensity reduction targets ($tCO_2e$ per unit of production) allocated to designated consumers across steel, cement, chlor-alkali, aluminum, and petrochemical sectors.
2. Trading Architecture:
   • Registry: Grid Controller of India Limited (Grid-India) acts as the central registry.
   • Market Administrator: Bureau of Energy Efficiency (BEE) formulates rules, verification procedures, and targets.
   • Regulator: Central Electricity Regulatory Commission (CERC) regulates trading operations across recognized power exchanges.
3. Transition from PAT to CCTS: Phased absorption of the legacy Perform, Achieve and Trade (PAT) scheme into the broader greenhouse gas (GHG) compliance ecosystem.

Strategic Significance for India’s NDCs and Industry

• Mitigating EU CBAM Impacts: Establishing a verified domestic carbon price mechanism allows Indian industrial exporters to claim offsets against cross-border carbon border adjustment taxes, like the EU Carbon Border Adjustment Mechanism (CBAM).
• Incentivizing Industrial Decarbonization: Provides clear financial returns for adopting green hydrogen, carbon capture, utilization, and storage (CCUS), and industrial heat recovery.
• Achieving NDC Commitments: Helps fulfill India’s updated Nationally Determined Contributions (NDCs) targeting a 45% reduction in GDP emissions intensity by 2030 (from 2005 levels).

[Downstream Flash Flood Surge] ◄── [Erosion & Catastrophic Dam Breach] ◄────────┘

• Structural Vulnerability: Moraine dams comprise loose, unconsolidated glacial debris, rocks, and ice cores lacking structural cohesion.
• Primary Triggers: Permafrost degradation, rockfall/ice avalanches falling into glacial lakes, and localized extreme precipitation events (cloudbursts) causing sudden surges in hydrostatic pressure.

Strategic Interventions under the Framework

1. Multi-Hazard Early Warning Systems (MHEWS): Automated Weather Stations (AWS), water-level radar sensors, and acoustic flood sirens connected via satellite communication links (INSAT/NavIC) to downstream population centers.
2. Engineered Siphoning & Controlled Drainage: Lowering lake volumes using high-density polyethylene (HDPE) siphon pipes, sub-surface spillway channels, and artificial outlet tunnels.
3. Prohibitory Riparian Zoning: Strict enforcement of the Model Disaster Management Land-Use Regulations, prohibiting heavy hydroelectric infra construction in identified critical runout zones.

Institutional & Ecological Challenges

• Extreme Altitude Logistics: Installing sensitive telemetry equipment at elevations exceeding 4,500 meters under sub-zero temperatures and high avalanche risks.
• Transboundary Glaciology: Many volatile glacial lakes originate across transboundary regions (e.g., Tibet/China), requiring cross-border hydrologic data sharing.
• High Sediment Load: Himalayan rivers carry heavy debris-to-water ratios, which can quickly overwhelm downstream engineering measures.

6. Mainstreaming Climate-Resilient & Bio-Fortified Crops: Redefining Food and Nutritional Security

Syllabus Mapping:

• GS Paper III: Major crop patterns in various parts of the country; Issues related to direct and indirect farm subsidies and minimum support prices; Public Distribution System—objectives, functioning, limitations.
