3 April 2025

• Security: AFSPA enforcement geography remained active. Disturbed area notifications cover Jammu and Kashmir, Assam, Nagaland, and parts of Manipur and Arunachal Pradesh.
• Nuclear: The IAEA's mandate and inspection role entered policy discussions around India's reactor expansion.
• Environment: Nilgiri Biosphere Reserve continued to surface in biodiversity coverage as a benchmark for multi-state conservation.
• Defence: India's Nag Missile System demonstrated the third-generation fire-and-forget anti-tank capability from the NAMICA tracked vehicle.

AFSPA remained in news in early April 2025 as Parliament discussed the security situation in the northeast and Jammu and Kashmir.

• Enactment: 1958.
• Trigger: Applies to areas declared "disturbed" by the Central Government, the State Governor, or the UT Administrator.
• Powers granted: Security forces may prohibit gatherings of five or more people, use force after giving warning, arrest without a warrant, and seize firearms.
• Current enforcement zones: Jammu and Kashmir, Assam, Nagaland, parts of Manipur (excluding Imphal municipal area), and parts of Arunachal Pradesh.
• Controversy: The Act shields security personnel from prosecution without Central Government sanction. Courts have repeatedly reviewed this protection.

The key prelims trap is the declaration authority. The Central Government (not just the army or state government) can declare a disturbed area. States can also do so in some versions, making the exact chain of authority the testable point.

The International Atomic Energy Agency's mandate resurfaced in discussions of India's nuclear expansion and the US SMR deal.

• Role: Conducts inspections of nuclear facilities worldwide to ensure compliance with NPT commitments and verifies that nuclear material is used for peaceful purposes.
• Mandate: Does not supervise nuclear weapon disarmament. The IAEA verifies non-weapons states only, not the nuclear weapon states' arsenals.
• India's position: India is not an NPT signatory. The India-specific safeguards agreement (2008) allows IAEA access to India's civilian reactors only, not its military programme.

The Nilgiri Biosphere Reserve continues to be a reference point for multi-state conservation governance.

• Location: Spans Karnataka, Kerala, and Tamil Nadu across the Western Ghats.
• UNESCO recognition: Designated under the UNESCO Man and the Biosphere programme.
• Protected areas within it: Nagarahole, Mudumalai, Bandipur (Karnataka), Wayanad (Kerala), and Mukurthi (Tamil Nadu) national parks and sanctuaries.
• Endemic species: The star-eyed bush frog (Raorchestes signatus) is among the many endemic species in the reserve.
• Significance: One of the largest biosphere reserves in the country and a critical corridor for elephants and tigers.

The Nag Missile System represents a key milestone in India's indigenous anti-tank guided missile programme.

• Classification: Third-generation fire-and-forget anti-tank guided missile. "Third generation" means the gunner does not need to guide the missile after launch.
• Developer: Defence Research and Development Organisation (DRDO).
• Launch platform: NAMICA (Nag Missile Carrier), a tracked amphibious vehicle.
• Warhead: Tandem HEAT (High-Explosive Anti-Tank), designed to defeat Explosive Reactive Armour (ERA) on modern battle tanks.
• Guidance: Imaging Infrared seeker. Once locked on, the missile homes in autonomously.

Hypersonic missiles entered the defence analysis spotlight amid reports of several countries testing new weapons.

• Defining characteristic: Mid-flight maneuverability. This is what distinguishes them from ballistic missiles, which follow predictable parabolic trajectories.
• Speed threshold: Mach 5 or above (five times the speed of sound).
• Types: Hypersonic Glide Vehicles (HGVs) are launched on ballistic trajectories and then glide unpredictably. Hypersonic Cruise Missiles are powered throughout flight.
• Why they matter: Existing missile defence systems are designed for ballistic trajectories. Hypersonic maneuverability makes them far harder to intercept.

Research on pathogen spillover between managed honeybee colonies and wild pollinators raised conservation concerns in April 2025.

• Mechanism: Disease pathogens from commercial honeybee operations spread to wild pollinators when managed bees and wild insects share foraging zones or nest sites.
• Double effect: Spillover reduces biodiversity in wild pollinator populations. Spillback (pathogens moving from wild to managed bees) increases disease severity in commercial hives.
• Relevance: Pollinator decline threatens food security because a large proportion of food crops depend on insect pollination. UPSC frequently links this to biodiversity conventions.

• International Energy Efficiency Hub (IEEH): Successor to IPEEC, established in 2020. Has 16 members including the USA, UK, China, Germany, and Japan. India is represented by the Bureau of Energy Efficiency (BEE). Prelims angle: which ministry BEE falls under (Ministry of Power).
• Union and State Government borrowing: Article 292 governs Union borrowing against the Consolidated Fund. Article 293 governs state borrowing; a state must obtain Central Government consent if it has outstanding loans from the Union. Both borrowing powers are subject to legislative sanction.
