Subtopic: International Relations & Maritime Security
Value Addition:
- Location: East China Sea, NE of Taiwan, W of Okinawa (Japan).
- Composition: 8 small islands (total area: ~6.3 sq. km).
- Current Control: Japan (Okinawa Prefecture).
- Claimants:
  - Japan: Incorporated in 1895 as terra nullius.
  - China/Taiwan: Claim historical ownership (Ming-era maritime records).
- Strategic Value:
  - Lies on major shipping lanes & near hydrocarbon-rich seabeds.
  - Rich fisheries; proximity to U.S.–Japan military routes.
- Recent Tension:
  - Chinese Coast Guard incursion (2025) → maritime standoff.
  - U.S. reaffirmed support under U.S.–Japan Security Treaty (1972).
Subject Analysis:
- Symbol of Sino-Japanese rivalry in Indo-Pacific.
- Critical for freedom of navigation & Quad’s maritime strategy.
- Relevant for GS2 – IR / Security / Indo-Pacific Affairs.

Subtopic: Internal Security & Chemical Regulation
Value Addition:
- Formula: NH₄NO₃ | Nature: White crystalline solid; salt of ammonia + nitric acid.
- Uses:
  - Agriculture – High-nitrogen fertilizer.
  - Mining/Construction – Oxidizing agent in slurry explosives.
  - Medical – Used in labs & gas production.
- Why Explosive:
  - Stable alone; becomes explosive when mixed with fuel oil/kerosene (ANFO mixture).
  - Requires detonator; rapid decomposition releases N₂, O₂, H₂O vapour, causing high heat & shockwaves.
- Regulation (India):
  - Ammonium Nitrate Rules 2012 (amended 2021): >45% content = explosive.
  - PESO – Regulates manufacture, storage, and transport.
  - District Magistrate – permits up to 30 MT; PESO approval for larger quantities.
- Issues: Misuse in illegal mining & terror attacks; need for digital tracking & warehouse compliance.
Subject Analysis:
- Example of dual-use industrial material with national security implications.
- Reinforces hazard management, regulation, and accountability.
- Relevant for GS3 – Internal Security / Disaster Management.

Subtopic: Marine Biodiversity & Climate Indicators
Value Addition:
- Type: Microscopic single-celled marine protists (8,000 species).
- Habitat:
  - Planktonic (floating) & Benthic (sea-floor) forms.
- Structure:
  - Have calcareous or agglutinated shells (tests) with pores (“foramina”).
  - Size: 0.1–20 mm; move using pseudopodia.
- Ecological Roles:
  - Feed on bacteria, algae, detritus; recycle organic matter.
  - Sensitive to oxygen & acidity → excellent bioindicators.
- Scientific Use:
  - Paleo-climate reconstruction via oxygen isotopes.
  - Oil exploration & stratigraphic dating.
- New Discovery (2025): 57 new living species identified globally.
Subject Analysis:
