Shaheed Diwas (Martyrs' Day) is observed on 23 March every year to commemorate the execution of Bhagat Singh, Sukhdev Thapar, and Shivaram Rajguru at Lahore Central Jail by the British colonial administration in 1931.

• Background: The three revolutionaries were convicted for the killing of British police officer John Saunders in Lahore in December 1928. Their actual target was James A. Scott, the Superintendent of Police who had ordered the baton charge that fatally injured Lala Lajpat Rai during a protest against the Simon Commission.
• Lala Lajpat Rai: Known as "Punjab Kesari" (Lion of Punjab), Rai died of injuries sustained in the police lathi charge in November 1928. Bhagat Singh and his associates considered his death a direct consequence of official brutality and vowed retribution.
• Ideology: Bhagat Singh was an avowed socialist and atheist. His pamphlet "Why I am an Atheist" (written in prison) remains a canonical text in Indian rationalist thought. He was influenced by Marx, Lenin, and Trotsky.
• Hunger strike: While in prison, Bhagat Singh and Batukeshwar Dutt undertook a 64-day hunger strike demanding that political prisoners be treated with dignity and granted access to books, newspapers, and adequate food.
• HSRA: Bhagat Singh, along with Chandrashekhar Azad, was a key organiser of the Hindustan Socialist Republican Association (HSRA), which advocated armed struggle alongside mass mobilisation.
• Two Martyrs' Days: India observes 23 March as Shaheed Diwas for Bhagat Singh, Sukhdev, and Rajguru. A separate Shaheed Diwas (also called Martyrs' Day) is observed on 30 January in remembrance of the assassination of Mahatma Gandhi.

GS Paper I: Geography, Climate, Disaster Management

California received 147% of its average seasonal rainfall in the winter of 2022-23 after being hit by 11 consecutive atmospheric rivers, a meteorological phenomenon increasingly understood as a pivotal but volatile component of the global water cycle.

• What is an atmospheric river: An atmospheric river is a long, narrow, and transient corridor of concentrated water vapour in the lower atmosphere, typically 2,000 km or more in length and 400-600 km wide, transporting moisture from tropical and subtropical regions to higher latitudes. They are often called "rivers in the sky."
• Moisture volume: A single large atmospheric river can transport as much water vapour as 15 times the average discharge of the Mississippi River.
• Pineapple Express: The most famous atmospheric river affecting California originates near Hawaii and is colloquially called the "Pineapple Express."
• Climate change projection: Warming temperatures allow the atmosphere to hold more water vapour (approximately 7% more per degree Celsius of warming, per the Clausius-Clapeyron relation). Research projects that atmospheric rivers will become longer, more intense, and carry higher moisture loads under global warming.
• Paradox of wet years: A paradox observed in California: wet years following dry years deposit large amounts of vegetation on hillsides, which dries out in summer and becomes wildfire fuel, creating a vicious cycle of flood followed by fire.
• India relevance: India experiences its own form of atmospheric river-like moisture transport during the southwest monsoon via the Low-Level Jet Stream over the Arabian Sea. Cloudbursts in the Himalayan foothills share some mechanistic similarities.

GS Paper II: Indian Polity, Judiciary, Fundamental Rights

The Supreme Court raised the question of whether hanging, the sole prescribed method of execution under Indian law, remains the only acceptable method in a humane criminal justice system, inviting the government's response on alternatives.

• Legal provision: Section 354(5) of the Code of Criminal Procedure (CrPC) mandates that a person sentenced to death "shall be hanged by the neck till he is dead." The corresponding provision in the Bharatiya Nagarik Suraksha Sanhita (BNSS, 2023 successor to CrPC) preserves this.
• Bachan Singh v. State of Punjab (1980): The Supreme Court's Constitution Bench upheld the constitutionality of capital punishment but confined its application to the "rarest of rare cases." It established the principle of weighing aggravating factors against mitigating circumstances.
• Machhi Singh (1983): Further refined the "rarest of rare" doctrine with five categories of cases that may justify the death penalty, including cases involving multiple murders with extreme brutality.
• International landscape: As of 2023, 55 countries retain capital punishment in law and practice. Methods in use globally include lethal injection (United States, China), hanging (India, Japan, Iran), firing squad, electrocution, and beheading (Saudi Arabia). The UN General Assembly has repeatedly called for a moratorium on executions.
• Pending cases: Approximately 539 prisoners were on death row in India as of 2022, with most convictions related to murder and sexual assault.

GS Paper II: Indian Polity, Governance, Democratic Institutions

The Varieties of Democracy (V-Dem) Institute's annual report (released March 2023) flagged a decline in India's democratic quality across multiple indices, with some scores approaching levels not seen since the Emergency period of 1975-77.

• What V-Dem measures: The V-Dem project measures five high-level democracy principles: electoral democracy (free and fair elections), liberal democracy (rule of law, constraints on executive), participatory democracy (civil society participation), deliberative democracy (reasoned public justification), and egalitarian democracy (equal access to political participation).
• India's trajectory: V-Dem data showed deterioration from 2014 onwards, with indices for media freedom, judicial independence, civil society space, and academic freedom showing the steepest declines.
• Government response: The Indian government has consistently rejected such third-party democracy rankings, citing their methodological biases and the absence of lived democratic practice from their models.
• Internet shutdowns: India led the world in internet shutdowns in 2022, with 84 shutdowns recorded, more than any other country. Shutdowns affect political communication, economic activity, and access to information.
• Comparative perspective: V-Dem classified India as an "electoral autocracy" from 2018 onwards, a designation contested by the government and many scholars who point to continued free elections, an active judiciary, and a vibrant press.

India carries the world's highest tuberculosis burden, accounting for approximately 27% of global TB cases in 2022. The government has set an ambitious target of TB elimination (defined as fewer than one case per million population) by 2025, five years ahead of the global Sustainable Development Goal of 2030.

• WHO milestones: The WHO declared TB a global emergency in 1993. The Stop TB Partnership was founded in 2001. The Global Fund to Fight AIDS, Tuberculosis and Malaria was established in 2002.
• National TB Elimination Programme (NTEP): India's programme, previously called RNTCP (Revised National Tuberculosis Control Programme), renamed in 2020 to reflect the elimination goal. Key interventions: free diagnosis (CB-NAAT and TrueNAT machines for molecular testing), free drugs (including bedaquiline and delamanid for drug-resistant TB), and the Ni-kshay Poshan Yojana (nutritional support of Rs 500 per month to TB patients).
• TN-KET model: Tamil Nadu's Kasanoi Erappila Thittam (TN-KET) project achieved a reduction in TB deaths from approximately 600 per month to 350 per month between April and December 2022, through intensive case-finding and community health worker engagement.
• Drug-resistant TB: Multi-drug resistant (MDR-TB) and extensively drug-resistant (XDR-TB) are the principal threats to elimination. India has one of the highest MDR-TB burdens globally.
• Private sector engagement: Private providers diagnose the majority of TB patients in India but historically under-notified cases, fuelling transmission. Mandatory notification of TB cases was introduced in 2012.

GS Paper II: International Relations, Trade Agreements

The Indo-Pacific Economic Framework for Prosperity (IPEF), launched in May 2022 by the United States, is a US-led economic grouping covering approximately 40% of global GDP. India is a founding member.

• Membership: 14 member countries including the US, India, Japan, South Korea, Australia, New Zealand, Singapore, Indonesia, Thailand, Vietnam, Philippines, Malaysia, Fiji, and Brunei. Notably excludes China.
• Four pillars:
  • Pillar I (Trade): Fair and resilient trade, digital trade, labour standards, environment.
  • Pillar II (Supply Chains): Resilient supply chains, reducing dependence on single-source critical minerals and semiconductors.
  • Pillar III (Clean Economy): Clean energy, decarbonisation, carbon removal, infrastructure investment.
  • Pillar IV (Fair Economy): Tax transparency, anti-corruption, anti-money laundering.
• India's nuanced membership: India joined all four pillars at the IPEF launch but later indicated it would not sign the Trade Pillar (Pillar I) agreement, citing concerns about labour and environmental standards being linked to market access.
• Significance: IPEF does not offer traditional market access (tariff reductions) like an FTA. Critics argue this limits its attractiveness for developing economies; proponents say it builds supply chain and standards cooperation outside a tariff framework.

GS Paper I: Physical Geography, Geomorphology

Zealandia, a largely submerged continental landmass in the southwestern Pacific Ocean, has attracted renewed scientific interest as geologists continue to map its structure and history.

• Size: Zealandia covers approximately 4.9 million square kilometres (1.89 million square miles), making it roughly two-thirds the size of Australia.
• Submergence: Approximately 94% of Zealandia lies beneath the Pacific Ocean. The only areas above sea level are New Zealand (North and South Islands and Stewart Island), New Caledonia, and Norfolk Island.
• Geological origin: Zealandia was part of the ancient supercontinent Gondwana. It separated from Gondwana (specifically from Antarctica and Australia) approximately 105 million years ago, gradually subsiding as it rifted away.
• Continental crust: Zealandia meets the geological criteria for a continent: it has a continuous area, elevated topography relative to the surrounding ocean floor, a thick continental crust (30-40 km) distinct from oceanic crust, and recognisable geology.
• Eighth continent debate: Geoscience researchers formally proposed recognising Zealandia as a continent in a 2017 paper in GSA Today. No international body officially designates continents, so "eighth continent" remains a scientific proposition rather than an official designation.

GS Paper III: Environment, Infrastructure, Shipping

India's Green Tug Transition Programme (GTTP) aims to decarbonise port operations by replacing conventional diesel-powered tugboats with hybrid and green-fuel alternatives at major ports by 2025-30.

• Target ports: The programme initially covers five major ports: Jawaharlal Nehru Port (JNPA), Deendayal Port (Kandla), Paradip Port, V.O. Chidambaranar Port, and Syama Prasad Mookerjee Port (Kolkata).
• Alternative fuels: Methanol, green ammonia, liquefied natural gas (LNG), and green hydrogen are the candidate marine fuels. Hybrid electric-diesel tugs are a near-term bridge option.
• Maritime Amrit Kaal Vision 2047: The GTTP is part of India's Maritime Amrit Kaal Vision 2047, which targets net-zero emissions from the shipping and port sector.
• IMO targets: The International Maritime Organization (IMO) revised its greenhouse gas reduction strategy in 2023 to target net-zero shipping emissions by 2050. India as a major shipping nation is committed to IMO compliance.
• Sagarmala Programme: The GTTP aligns with the Sagarmala Programme's port modernisation component, which includes port-led development, coastal shipping, and inland waterways integration.
