  • Protects civilians

  • Coordinates with Israel, Egypt, Palestinian security forces

Subject Analysis:

• Reflects UNSC’s attempt to combine reconstruction + security guarantees.

• Shows increasing trend of transitional international bodies in conflict zones.

• Useful for GS-2 IR → UN reforms, peacekeeping, West Asia geopolitics.

5. NATGRID – National Intelligence Grid

Subtopic: Homeland Security + Integrated Intelligence Architecture

Value Addition:

• Processes ~45,000 requests/month from agencies.

• Post-26/11 initiative; conceptualised 2009; operational since 2020.

• Users: IB, RAW, NIA, ED, FIU, NCB, DRI + SP-rank officers.

• Data Sources Integrated:

  • Immigration (entry/exit)

  • Banking & financial transactions

  • Telecom records

  • Credit card data

  • IT filings

  • Air + rail passenger data

• Technology: Big Data + Analytics for pattern detection, suspect tracing, threat modelling.

Subject Analysis:

• Key pillar of India’s counter-terror + financial intelligence framework.

• Enhances inter-agency collaboration, reducing “information silos”.

• Raises debates on privacy, data protection, and operational accountability.

• Useful for GS-2 governance + GS-3 internal security.

GS–3 | ENVIRONMENT / BIODIVERSITY

6. Dolomedes indicus – New Fishing Spider Species (Western Ghats)

Subtopic: Taxonomy, Freshwater Ecology, Indicator Species

Value Addition:

• Newly discovered in Wayanad (Kerala).

• First Indian species of Dolomedes (raft/fishing spiders).

• Behavioural Traits:

  • Semi-aquatic predator

  • Hunts using surface vibration detection

  • Can walk on water, swim, dive

• Sexual Dimorphism:

  • Males → snow-white marking from face to mid-back

  • Females → larger, greenish-brown for camouflage

• Habitat: Cool, clean forest streams with heavy shade.

• Highly sensitive to pollution → potential bioindicator species.

Subject Analysis:

• Adds to the Western Ghats’ status as a global biodiversity hotspot.

• Useful for questions on niche species, evolution of predation mechanisms, and freshwater ecosystem health.
