General Studies Paper I: Heritage, Geography & Society
1. Epigraphical Discoveries in Badami & the Evolution of Vesara Temple Architecture
- Syllabus Tag: GS-I: Indian Culture – Salient aspects of Art Forms, Literature, and Architecture from ancient to modern times.
- Source:The Hindu
Context
A newly documented Sanskrit inscription in the Siddhamatrika script at the Badami Cave Complex has offered fresh insights into royal patronage of cave excavations and the transition toward the Vesara (Karnataka Dravida) architectural style under the Early Western Chalukyas of Vatapi (6th–8th century CE).
Architectural & Epigraphical Significance
- Vesara Style Synthesis: Blends the northern Nagara shikharas (curvilinear towers) with the southern Dravidian vimana (stepped pyramidal towers), terraced storeys (talas), and pillared mandapas.
- Cave Excavation Typology: Cave 3 (dedicated to Vishnu) and Cave 1 (dedicated to Shiva as Nataraja with 18 arms) exhibit rock-cut subterranean structural techniques developed prior to the monolithic free-standing shrines at Aihole (Lad Khan, Durga Temple) and Pattadakal.
- Pattadakal as a UNESCO World Heritage Complex: Demonstrates the coexistence of pure Nagara (Papanatha Temple) and pure Dravida (Virupaksha Temple) temples constructed by Queen Lokamahadevi to commemorate Vikramaditya II’s victory over the Pallavas of Kanchipuram.

Prelims Key Takeaways
- Aihole: Frequently termed the “Cradle of Indian Temple Architecture”; home to the famous Aihole Inscription composed by Ravikirti, court poet of Pulakeshin II (referencing the defeat of Harshavardhana on the banks of the Narmada).
- Patronage: Early Western Chalukyas of Badami followed by the Rashtrakutas of Manyakheta (who sculpted the monolithic Kailash Temple at Ellora, Cave 16).
2. Himalayan Glacial Lake Outburst Floods (GLOFs) & Cryospheric Vulnerability
- Syllabus Tag: GS-I: Geophysical phenomena; Changes in critical geographical features (including water-bodies and ice-caps).
- Source:The Indian Express
Context
A comprehensive vulnerability audit of over 28,000 glacial lakes across the Hindu Kush-Himalaya (HKH) region, conducted by the National Disaster Management Authority (NDMA) and the Wadia Institute of Himalayan Geology, categorized 188 lakes in Sikkim, Himachal Pradesh, Ladakh, and Uttarakhand as “high risk” for catastrophic Moraine-Dam Failure.
Dynamics of Moraine-Dam Breaches
- Accelerated Glacial Retreat: Climate change induces rapid ablation of valley glaciers, causing meltwater to collect behind unstable lateral or terminal moraines composed of unconsolidated glacial debris and ice-cored rock dams.
- Triggering Events: Avalanches, seismic tremors, rockfalls, or intense cloudbursts breach the fragile moraine walls, triggering an instantaneous release of hydrostatic pressure and downstream flash floods carrying heavy sediment loads.
- Cascading Hazards: GLOF floodwaters inundate run-of-the-river hydroelectric power projects, destabilize highway infrastructure along fragile river corridors (e.g., Teesta, Alaknanda basins), and destroy riparian habitats.
| Parameter | High-Risk Glacial Lake (e.g., South Lhonak) | Low-Risk Glacial Lake |
| Moraine Composition | Ice-cored, unconsolidated sediment | Consolidated rock/bedrock sill |
| Freeboard Height | Low ($<10\text{ meters}$) | High ($>30\text{ meters}$) |
| Surge Wave Risk | High (steep hanging glaciers directly above) | Minimal hanging ice or rock avalanche risk |
| Drainage Siphoning | Absent or nascent | Managed via automated controlled siphons |
Policy & Mitigation Framework
- Installation of Automated Water Level Recorders (AWLRs) and seismic trip-wire early warning systems linked via satellite communications.
- Controlled Siphoning: Deployment of High-Density Polyethylene (HDPE) siphon pipes to systematically lower the baseline water volume of vulnerable glacial lakes.
General Studies Paper II: Polity, Governance & International Relations
3. Demographic Divergence and Constitutional Delimitation Challenges
- Syllabus Tag: GS-II: Indian Constitution – Salient features, Parliament and State Legislatures—structure, functioning, conduct of business, powers & privileges.
- Source:The Hindu
Context
With the constitutional freeze on the total number of parliamentary seats (mandated by the 84th Constitutional Amendment Act until after the relevant figures for the first census taken after the year 2026 are published) coming under active policy discourse, questions over equitable representation and fiscal-political federalism have resurfaced.
Constitutional Architecture of Delimitation
- Article 81 & Article 82: Provide for the composition of the Lok Sabha and the readjustment of seats across states following every decennial census.
- 42nd Amendment (1976): Froze the allocation of seats based on the 1971 Census to incentivize population control policies.
- 84th Amendment (2001) & 87th Amendment (2003): Extended the total seat allocation freeze until the post-2026 census while allowing intra-state boundary realignments based on the 2001 Census figures.

Federal Constitutional Dilemma:
Balancing Pure Democratic Weight vs. Asymmetric Federalism
Structural Dilemmas
- The Federal Representation Penalty: Southern states that successfully reduced Total Fertility Rates (TFR) below the replacement level of 2.1 risk losing proportional seat shares relative to northern states experiencing ongoing demographic expansion.
- Normative Principle of Equal Vote Value: A pure population-to-seat ratio requires roughly equal citizen representation per Member of Parliament, conflicting with geographical equity principles across states.
Institutional Solutions Under Review
- Expanding the Rajya Sabha’s federal powers or revising seat allocations to provide equal state representation (similar to the US Senate model).
- Retaining weighted voting or fixing a constitutional baseline floor for total representation in the Lower House.
4. Expansion of the International North-South Transport Corridor (INSTC) and the Chabahar Rail Link
- Syllabus Tag: GS-II: Bilateral, regional and global groupings and agreements involving India and/or affecting India’s interests; Effect of policies and politics of developed and developing countries.

6. Basel III “Endgame” Implementation & Capital Surcharges for Domestic Systemically Important Banks (D-SIBs)
- Syllabus Tag: GS-III: Indian Economy and issues relating to planning, mobilisation of resources, growth, development and employment.
- Source:The Hindu Business Line
Context
The Reserve Bank of India (RBI) mandated that Domestic Systemically Important Banks (D-SIBs)—including State Bank of India, HDFC Bank, and ICICI Bank—transition to revised standardized approaches for credit, operational, and market risks under the Basel III Endgame framework.
Core Structural Requirements
- Higher Common Equity Tier 1 (CET1) Surcharges: Requires designated D-SIBs to maintain an incremental CET1 capital buffer ranging from $0.20\%$ to $0.80\%$ of Risk-Weighted Assets (RWAs) over the standard Capital Adequacy Ratio (CAR) of $11.5\%$.
- Standardized Measurement Approach (SMA) for Operational Risk: Eliminates the Advanced Measurement Approach (AMA), replacing internal bank models with an indicator based on gross income and historical operational loss data.
- Output Floor Implementation: Restricts total model-driven internal risk evaluations from dropping below $72.5\%$ of standardized risk calculations, reducing the underestimation of capital requirements.
