True Polar Wander (TPW) Subtopic: Earth’s Rotational Axis Shift and Mass Redistribution
Value Addition:
Human-built dams since 1835 have shifted Earth’s rotational axis by over 1 meter.
TPW is caused by mass redistribution (e.g., glaciers melting, tectonic drift, ocean swell shifts).
Dams hold inland water that alters Earth’s angular momentum and gravitational equilibrium.
Consequences: Disruption of satellite tracking, GPS reliability, and even a gradual increase in day length.
Subject Analysis:
GS 1: Geography – Earth’s geophysical systems and human-environment interaction.
GS 3: Environment – Anthropogenic impact on planetary systems.
Prelims: TPW, axial tilt, dam-based mass redistribution.
Zonal Cultural Centres (ZCCs) Subtopic: Decentralised Preservation of Folk and Tribal Heritage
Value Addition:
7 ZCCs (e.g., Patiala, Nagpur, Udaipur) work under the Ministry of Culture to revive and promote vanishing art forms.
Engage youth through cultural events, competitions, and apprenticeship programs.
Provide financial and institutional support to lesser-known tribal traditions.
Subject Analysis:
GS 1: Culture – Government role in intangible heritage preservation.
Prelims: List of ZCC HQs, Ministry of Culture initiatives.

Geelong Treaty (AUKUS) Subtopic: Bilateral Defence Technology Sharing between UK & Australia
Value Addition:
A 50-year agreement under AUKUS Pillar-I for joint development of SSN-AUKUS submarines.
Reflects growing Indo-Pacific strategic consolidation amid US hesitance.
Supports long-term capacity-building in nuclear propulsion for non-nuclear weapon states (with safeguards).
Subject Analysis:
GS 2: IR – Defence alliances, power projection in the Indo-Pacific.
Prelims: AUKUS structure, Pillar I vs Pillar II, Geelong Treaty.
Environment Protection (Management of Contaminated Sites) Rules, 2025 Subtopic: Framework for Legacy Hazardous Waste Remediation
Value Addition:
India’s first time-bound and legally binding remediation framework.
CPCB identifies 103 contaminated sites; only 7 cleaned so far.
Polluter-pays principle enforced; fallback mechanism for government funding if polluter absconds.
Includes criminal penalties under Bharatiya Nyaya Sanhita (2023).
Subject Analysis:
GS 2: Governance – Environmental rule enforcement, decentralised reporting.
GS 3: Environment – Hazardous waste regulation.
Prelims: CPCB, exclusion clauses (radioactive, marine, landfill, mining).

State of Food Security & Nutrition in the World (SOFI) 2025 Subtopic: India’s Nutritional Burden & Global Hunger Landscape
Value Addition:
India has highest under-5 wasting globally (18.7%) and 53.7% women anaemic.
Adult obesity doubled to 71M; healthy diet unaffordable for 43% of Indians.
Joint report by FAO, IFAD, WFP, WHO, and UNICEF since 1999; tracks SDG 2 progress.
Subject Analysis:
GS 3: Economy – Nutrition economics, inflation impact on food security.
GS 2: Welfare – Malnutrition and public health.
Prelims: SDG 2, SOFI agencies, trend data.
Divya Drishti Exercise Subtopic: Battlefield AI and Sensor-to-Shooter Integration
Value Addition:
Indian Army conducted exercise in high-altitude East Sikkim to test AI-powered surveillance and decision support.
Utilised UAVs, drones, and ground sensors integrated with AI for real-time intel-sharing.
Conducted by Trishakti Corps under Eastern Command.
Subject Analysis:
GS 3: Defence – Indigenous tech adoption, real-time battlefield logistics.
GS 3: Science & Tech – AI in combat, sensor-networks.
Prelims: Trishakti Corps, Sukna HQ, East Sikkim.
