01 · GS-II: Indian Constitution, Delimitation & Federalism

The Constitutional Freeze on Lok Sabha Delimitation: Demographic Federalism, Article 82 and Representation Asymmetries

NEWS PEG
  • Constitutional experts and regional policy forums convened to evaluate the impending expiry of the delimitation freeze originally instituted under the 42nd Amendment (1976) and extended until the first census post-2026 under the 84th Constitutional Amendment Act, 2001.
  • Demographic projections indicate that a pure population-based reallocation of the 543 Lok Sabha seats based on post-2026 census data would expand northern States' representation (e.g. Uttar Pradesh from 80 to ~143, Bihar from 40 to ~79) while reducing or freezing the proportional share of southern States (Kerala, Tamil Nadu, Andhra Pradesh, Telangana, Karnataka) despite their success in achieving total fertility replacement (TFR ≤ 1.8).
  • Scholars highlighted the need for institutional mechanisms—such as capping lower house seats while redistricting internally or empowering the Rajya Sabha through equal state representation—to prevent penalizing demographic stabilization.
STATIC FOUNDATION
  • Articles 81 & 82: Article 81 defines the composition of the House of the People; Article 82 mandates readjustment of seats and territorial constituencies after each decennial Census by a statutory Delimitation Commission.
  • Article 170: Governs the composition and territorial delimitation of State Legislative Assemblies.
  • 84th & 87th Constitutional Amendments: The 84th Amendment (2001) froze the total number of parliamentary and assembly seats till 2026; the 87th Amendment (2003) allowed internal constituency rationalization based on 2001 Census figures without changing inter-State quotas.
PRELIMS TRAP & PYQ BRIDGE MAINS ENHANCEMENT
  • Federal Principle: Demographic Stabilization Compact — Preserving the constitutional assurance that population control policies will not lead to legislative marginalization.
  • Institutional Reform Option: Internal Intra-State Rationalization — Equalizing seat sizes within each State while maintaining existing inter-State parliamentary seat ratios.
  • Second Chamber Federalization: Empowering the Council of States (Rajya Sabha) — Exploring equal or weighted state representation to safeguard federal balance.

  • A global climate vulnerability report highlighted that low-income and agrarian populations in South Asia face a 15-fold higher mortality risk from extreme heat, floods, and droughts compared to developed nations with equivalent physical exposure.
  • The study demonstrated that climate impacts are non-equitable, functioning as a poverty multiplier that erodes informal livelihoods, forces distress migration, and consumes up to 30% of annual household income in post-disaster out-of-pocket recovery.
  • Ahead of the upcoming UNFCCC COP negotiations, developing nations pushed for operationalizing the newly established Loss and Damage Fund with direct, non-debt grants rather than concessionary loans.
STATIC FOUNDATION
  • Principle of Common But Differentiated Responsibilities and Respective Capabilities (CBDR-RC): Enshrined in Article 3(1) of the UNFCCC, recognizing that countries with historical emissions carry greater responsibility for climate finance.
  • Warsaw International Mechanism (WIM) & Santiago Network: Multilateral frameworks under the UNFCCC established to avert, minimize, and address loss and damage associated with climate change impacts.

NEWS PEG
  • Authorities in Jammu and Kashmir executed property attachments and demolished residences linked to active Lashkar-e-Taiba (LeT) operatives involved in militant attacks, invoking provisions under the Unlawful Activities (Prevention) Act (UAPA) and local municipal codes.
  • The actions renewed legal debates surrounding executive-led property demolitions ('bulldozer justice') versus the mandatory judicial pre-requisites for attachment and forfeiture of terrorist property.
  • Legal scholars highlighted the Supreme Court's clear doctrine that extra-judicial punitive demolitions violate Articles 14, 19, and 21, mandating that forfeiture of property must adhere strictly to statutory procedures laid down under Section 25 of the UAPA.
STATIC FOUNDATION
  • Section 25 of UAPA (1967): Empowers the Investigating Officer to seize or attach property representing proceeds of terrorism only with prior written approval from the designated authority (Director General of Police), subject to confirmation by the designated Special Court within 48 hours.

06 · GS-III: Urban Planning, Heat Hazards & Public Health

Extreme Urban Heatwave Records: Urban Heat Island (UHI) Physics, Wet-Bulb Limits and Heat Resilient Planning

NEWS PEG
  • Meteorological agencies recorded unprecedented heat emergencies across East Asian metropolitan centers, with Tokyo registering 453 emergency hospitalizations in a single day as ambient temperatures exceeded 39°C combined with extreme urban relative humidity.
  • Urban climatologists noted that the intensification of the Urban Heat Island (UHI) effect and high nighttime minimum temperatures prevent physiological heat dissipation, pushing vulnerable demographics past critical human wet-bulb temperature limits (35°C).
  • Indian municipal corporations were urged to update local Heat Action Plans (HAPs) to include mandatory nocturnal cooling corridors, reflective cool roof mandates, and heat-adjusted outdoor labour shifts.
STATIC FOUNDATION
  • Urban Heat Island (UHI) Effect: Microclimatic phenomenon where urban areas experience significantly higher temperatures than surrounding rural hinterlands due to high thermal mass (concrete, asphalt), reduced evapotranspiration, and anthropogenic waste heat.
  • Wet-Bulb Temperature: The lowest temperature achievable through evaporative cooling; sustained exposure to wet-bulb temperatures above 35°C impairs human thermoregulation and leads to fatal heatstroke.
  • National Disaster Management Authority (NDMA) Heat Action Guidelines: Recommends early heat warnings, public hydration points, white reflective roof coatings, and staggered working hours for outdoor workers.
