• Polity: The Supreme Court heard petitions challenging the Election Commission's Special Intensive Revision of electoral rolls in Bihar ahead of assembly elections. Over 8 crore voters are being re-verified.
• Environment: UNEP Frontiers Report 2025 warns that intensified flooding remobilises legacy toxic chemicals from river sediments. Cadmium in the Ganga, Hindon and Vaigai rivers exceeds safe limits.
• Population: UN World Population Day (11 July) focused on empowering young people on family planning. India has 371 million youth aged 15-29, the largest cohort globally.
• Defence: INS Nistar, India's first indigenous Diving Support Vessel, can deploy Deep Submergence Rescue Vehicles (DSRV).
• Economy: India's fisheries output doubled from 95.79 lakh tonnes (2013-14) to 195 lakh tonnes (2023-24).

GS area: Polity (elections, ECI)

The Election Commission of India launched a Special Intensive Revision (SIR) of electoral rolls in Bihar ahead of state assembly elections. The Supreme Court is hearing challenges to the process.

• Legal basis: Section 21(3) of the Representation of the People Act, 1950, allows intensive revision of electoral rolls.
• Scale: Over 8 crore voters in Bihar are being re-verified. 1 lakh Booth Level Officers and 4 lakh volunteers are conducting door-to-door verification.
• Timeline: Expected completion by 25 July 2025.
• Controversy: Petitioners argue the burden of proof has been shifted to voters. A post-2003 documentation divide creates arbitrary classification. Procedural irregularities in forms have also been reported.
• ECI's mandate: Article 324 vests superintendence, direction and control of elections in the Election Commission. The SIR is an exercise of that power.

The core tension is between maintaining clean rolls (deleting ghost voters) and ensuring no genuine voter is wrongly deleted before an election. Both are constitutional imperatives.

GS area: Environment (pollution, climate change)

The UNEP Frontiers Report 2025 titled "The Weight of Time" warned that intensified flooding is remobilising legacy toxic chemicals stored in river sediments.

• Mechanism: Industrial chemicals accumulated in river sediments over decades. Floods disturb these sediments and spread toxins downstream.
• India-specific: Cadmium levels in the Ganga, Hindon and Vaigai rivers exceed safe limits. Cadmium causes cancer and kidney damage at chronic exposure levels.
• Global cases: Hurricane Harvey (2017) spread mercury across Texas waterways. Niger Delta floods (2012) remobilised polycyclic aromatic hydrocarbons (PAHs).
• POP waste: 4.8 to 7 million tonnes of Persistent Organic Pollutant waste is stored in landfills globally, at risk in floods.
• Recommendations: Nature-based flood management solutions, integrated river basin management and systematic sediment pollution mapping.

GS area: Economy (agriculture, food security)

India's fish output doubled from 95.79 lakh tonnes in 2013-14 to 195 lakh tonnes in 2023-24. The sector is now the highest-ever recipient of central budgetary support.

• Budgetary support: 2,703.67 crore rupees for 2025-26, the highest ever allocation.
• PMMSY: Pradhan Mantri Matsya Sampada Yojana allocated 20,050 crore rupees for 2020-25. The flagship scheme for fisheries development.
• Exports: 17.8 lakh metric tonnes worth 60,524 crore rupees in 2023-24. Seafood is one of India's major agricultural export items.
• Inland aquaculture: Inland fish output increased by 77.71 lakh tonnes over the decade.

GS area: Defence

INS Nistar is India's first indigenous Diving Support Vessel (DSV).

• Role: Acts as a mother ship for Deep Submergence Rescue Vehicles (DSRVs). DSRVs rescue submarine crews in distress.
• Indigenous content: 80 per cent.
• Displacement: Over 10,000 tonnes.
• Length: 120 metres.
• Significance: India previously depended on foreign DSVs for submarine rescue. INS Nistar closes a critical operational gap.

India's S-400 Triumf long-range surface-to-air missile system is known as the Sudarshan Chakra in Indian service.

• Capability: Detects threats up to 600 km and engages targets up to 400 km. Can engage 80 simultaneous targets.
• Procurement: India contracted for 5 squadrons from Russia. Three have been delivered. Two are arriving by 2027.
• CAATSA context: The US Countering America's Adversaries Through Sanctions Act (CAATSA) targets countries buying major Russian military equipment. India received a waiver.
• Strategic value: The S-400 gives India layered air defence against ballistic missiles, aircraft and cruise missiles simultaneously.

GS area: Governance (tribal welfare, education)

The TALASH Initiative is a digital platform for holistic development and career planning of tribal students.

• Nodal Ministry: Ministry of Tribal Affairs.
• Coverage: 1.38 lakh-plus students across 28 states and 8 Union Territories by end of 2025.
• Features: Psychometric testing for career aptitude, life skills modules and self-awareness programmes.
• Objective: Enable informed career choices and prevent dropout among tribal students. Links to Project Udaan (prevented 30,000 child marriages) and Project Advika (11,000 child-marriage-free villages).
