• Defence: INS Aridhaman, India's third nuclear-powered ballistic-missile submarine, and INS Taragiri, a Project 17A stealth frigate, were commissioned, completing India's nuclear triad.
• Environment: Forest clearance was granted for Karnataka's Yettinahole drinking-water diversion project covering 111 hectares in the Western Ghats.
• Governance: Russia assured India of a 40 per cent increase in fertiliser supplies to cushion the West Asia shortfall.
• FCRA: The Foreign Contribution (Regulation) Amendment Bill 2026 continued to attract debate for provisions that allow automatic asset seizure without a hearing.

India commissioned INS Aridhaman (S4), completing what strategists call the nuclear triad: the ability to deliver nuclear weapons from land, air and sea.

• SSBN: Submersible Ship Ballistic Nuclear. An SSBN carries ballistic missiles with nuclear warheads and can remain submerged for weeks. Its survivability makes it the backbone of a second-strike capability.
• INS Aridhaman displacement: About 7,000 tonnes, larger than its predecessors INS Arihant (commissioned 2016) and INS Arighaat (commissioned August 2024).
• Missile payload: The K-15 Sagarika has a range of about 750 km. The K-4 missile has a range of about 3,500 km. Aridhaman likely carries the K-4 or the longer-range K-5.
• India's No First Use policy: India's declared nuclear doctrine commits it not to use nuclear weapons first. A credible second-strike capability from a survivable submarine platform makes this doctrine credible. Without sea-based deterrence, a land-based force is theoretically vulnerable to a disarming first strike.
• Six nuclear-triad nations: USA, Russia, China, UK, France and now India. India is the only country outside the P5 to have a full triad.
• INS Taragiri (Project 17A): A stealth guided-missile frigate. Project 17A is the Indian Navy's main warship construction programme under Aatmanirbhar Bharat.
• Advanced Technology Vessel (ATV) Project: India's classified submarine-building programme launched in the 1970s. Aridhaman is its most advanced product.

Stage 1 forest clearance was granted for the Yettinahole water-diversion project in Karnataka, which aims to bring drinking water from the Western Ghats to seven drought-prone districts.

• Project scope: A 252 km canal (208 km complete, 25 km under construction, 16 km pending). To benefit about 75 lakh people.
• Forest land diverted: 111.02 hectares, revised down from 173.31 hectares in an earlier plan. The revision added Rs 425 crore to project cost.
• Van (Samrakshan Evam Samvardhan) Adhiniyam, 1980: The Forest Conservation Act under which all forest diversion requires central approval. Stage 1 clearance from the Centre is followed by State action and then Stage 2 (final clearance).
• CAMPA: The Compensatory Afforestation Fund. Developers who divert forest land must pay into CAMPA to fund compensatory afforestation elsewhere.
• Net Present Value (NPV): A charge levied on forest diversion to account for the ecosystem services lost. NPV payment is separate from CAMPA contribution.
• Forest Rights Act, 2006: Any forest diversion must settle the rights of forest-dwelling communities under FRA before clearance is granted. Critics argued this pre-condition was not fully met in earlier phases of Yettinahole.
• Western Ghats sensitivity: The UNESCO-designated Ghats are a biodiversity hotspot and the source of rivers for peninsular India. Any diversion of Ghats catchment has downstream ecological consequences.

The draft tribal welfare plan for the Rs 92,000 crore Great Nicobar Island development project proposed relocating 62 families but was criticised for ambiguities and for not reflecting genuine consent.

• Project components: International Container Transhipment Port, airport, power plants and a township.
• Nicobarese: A Scheduled Tribe of the Andaman and Nicobar Islands. They are classified as a Particularly Vulnerable Tribal Group (PVTG). India has 75 PVTGs.
• Shompen: A separate PVTG on Great Nicobar, among India's most isolated communities.
• Free, Prior and Informed Consent (FPIC): A principle under the UN Declaration on Rights of Indigenous Peoples (UNDRIP). Consent must be given freely, before the project starts, and with full information. The Nicobarese withdrew consent in 2022; the government proceeded.
• Forest Rights Act, 2006: Forest rights of tribal communities must be settled before forest land is diverted. The Calcutta High Court was seized of a challenge to the environmental clearances on this ground.
• Strategic rationale: Great Nicobar sits at the entrance to the Malacca Strait through which about 80 per cent of China's oil imports pass. A transshipment port there has obvious strategic value, which is why the National Green Tribunal cited strategic importance in upholding the clearance.
• Scale of projected population: The island currently has about 10,000 Nicobarese. The project plan projects 3.36 lakh people by 2055. This is not development of the island for its existing inhabitants; it is replacement of them.

The government amended the Plastic Waste Management Rules (originally 2016) to allow a three-year carry-forward of missed recycling targets and introduced tradable Extended Producer Responsibility certificates.

• India's plastic waste: About 3.5 million tonnes generated annually. India ranks fourth globally in plastic waste generation.
• EPR (Extended Producer Responsibility): Holds producers, importers and brand owners responsible for the end-of-life management of their plastic packaging. Operationalised through a 2022 framework.
• Category I (rigid plastics) targets: 30 per cent recycled content by 2025-26, rising to 60 per cent by 2028-29.
• Single-Use Plastic ban (July 2022): 19 categories of single-use plastic items were banned.
• Basel Convention: India is a party to this convention on transboundary movement of hazardous waste, which covers certain categories of plastic waste.
• Compliance gap: Previous collection targets (35 per cent in 2021-22, rising to 100 per cent by 2024-25) were met only at 50-60 per cent. The 2026 amendment's three-year carry-forward is widely seen as a political concession to industry rather than a tightening of rules.

The Foreign Contribution (Regulation) Amendment Bill 2026, introduced in the Lok Sabha on 25 March, continued to attract opposition from civil society and state governments.

• FCRA 2010: Governs who may receive foreign donations and how they must be spent. Organisations receiving foreign funds must register with the Ministry of Home Affairs.
• Section 14B (proposed): Would end an organisation's FCRA registration automatically in specified circumstances, without a separate cancellation order and without a hearing.
• Section 16A (proposed): Foreign contributions and assets built from them can vest provisionally in a government-designated authority while proceedings are underway. In effect, the state can seize an NGO's foreign-funded property before any finding of wrongdoing.
• Audi alteram partem: The natural-justice principle that no one should be condemned without hearing. Automatic cessation violates it.
• 2020 amendments: Cut the administrative spending cap from 50 per cent to 20 per cent, banned sub-granting and mandated a single designated SBI branch for all foreign funds.
• Scale of licence cancellations: About 22,000 FCRA licences were cancelled between 2014 and 2026.
• Constitutional touchpoints: Article 14 (arbitrariness), Article 19(1)(c) (freedom of association), Article 300A (property), Articles 25, 26, 29, 30 (religious and minority rights). The sector contributes about 2 per cent of GDP.

• Russia-India energy cooperation: Russian Deputy PM Denis Manturov assured India of steady oil and LNG supplies and reported a 40 per cent increase in fertiliser deliveries as a direct response to West Asia disruptions. Russia is now India's largest crude supplier on the spot market.
• Strategic Petroleum Reserve: India's three underground storage facilities at Padur, Mangaluru and Visakhapatnam hold about 5.3 million tonnes. Phase II expansion at Chandikhol in Odisha is planned.
