9 June 2025

• Tribal history: 125th death anniversary of Bhagwan Birsa Munda (9 June 1900). His Ulgulan (Great Tumult) movement directly shaped the Chotanagpur Tenancy Act, 1908.
• Space: Axiom-4 mission launch postponed again; liquid oxygen leak in Falcon 9 booster detected. Indian astronaut Shubhanshu Shukla remained at Kennedy Space Center.
• Economy: World Bank raised the global extreme poverty line to $3 per day (PPP 2021). India's extreme poverty rate fell to 5.3 per cent in 2022-23, down from 16.2 per cent in 2011-12.
• Textile: India holds only 3 to 4.2 per cent of global textile and apparel trade at $37.8 billion, against a $40 billion export target for 2030.
• Science: Axiom-4 mission carries 60 scientific experiments from 31 countries. The Magnetic Isolation and Concentration (MagIC) technique enables cryo-EM imaging of samples 100 times more dilute than before.

Bhagwan Birsa Munda died on 9 June 1900 in British colonial custody at Ranchi Jail, aged 25. His 125th death anniversary was observed with national tributes.

• Birth: 15 November 1875, Ulihatu village, Chotanagpur (present-day Jharkhand).
• Title: "Dharti Aaba" meaning Father of the Earth. He is revered as a divine figure (Bhagwan) by tribal communities across Jharkhand, Odisha, and Bengal.
• The Ulgulan (Great Tumult): the armed uprising he led from 1895 to 1900 against British land dispossession and the landlord system (Diku-raj) that had transferred tribal lands to outsiders. The rebellion demanded restoration of Munda sovereignty (Munda Raj).
• Capture: arrested on 3 March 1900 while resting in Jamkopai forest. Died in custody on 9 June 1900. British authorities attributed his death to cholera; the circumstances remain contested.
• Legislative legacy: the Chotanagpur Tenancy Act, 1908, enacted partly in response to the Ulgulan. It restricts the transfer of tribal land in the Chotanagpur region to non-tribals, and remains the legal backbone of tribal land protection in Jharkhand.
• Janjatiya Gaurav Diwas: the Union Cabinet declared 15 November (Birsa Munda's birth anniversary) as Janjatiya Gaurav Diwas in 2021 to recognise tribal freedom fighters' contributions to India's independence struggle.
• PMJVK: Pradhan Mantri Janjati Vikash Kranti Yojana is a scheme for tribal welfare covering education, health, livelihood, and housing for Scheduled Tribes.

The exam hook: Birsa Munda appears both in the history of the freedom movement and in the tribal rights context. The Chotanagpur Tenancy Act and the Fifth Schedule (which protects tribal areas) are paired frequently.

GS area: Economy (Industry, Trade)

India's textile and apparel (T&A) industry is the second-largest employer in manufacturing but holds a disproportionately small share of global trade.

• Global share: India accounts for 3 to 4.2 per cent of global textile and apparel trade, valued at approximately $37.8 billion out of a global market of $897.8 billion.
• Employment: the sector employs over 45 million people. About 70 per cent of workers in major apparel hubs are women.
• GDP contribution: 2.3 per cent of India's GDP and 12 per cent of manufacturing employment.
• MSME dominance: over 80 per cent of apparel units are MSMEs (Micro, Small and Medium Enterprises), which limits scale and technology adoption.
• Export target: $40 billion in apparel exports by 2030, requiring roughly doubling the current share.
• Key government schemes: PM MITRA Parks (7 integrated textile parks, covering the full supply chain), Amended TUFS (Technology Upgradation Fund Scheme for machinery modernisation), RoSCTL (Refund of State and Central Taxes and Levies on exports), SAMARTH (skilling programme), and PLI Scheme for textiles.
• Challenge: India has lost share to Bangladesh and Vietnam, which benefit from lower wages, simpler GST structures for textiles, and preferential trade access to the EU.

The 17th edition of Exercise Nomadic Elephant took place in Ulaanbaatar, Mongolia (31 May to 13 June 2025).

• Partners: India and Mongolia.
• Indian contingent: 45 soldiers from the Arunachal Scouts regiment.
• Location: Special Forces Training Centre, Ulaanbaatar.
• Focus areas: counter-terrorism operations, peacekeeping, cyber awareness, and mountain warfare.
• Series background: Nomadic Elephant is the bilateral joint military exercise between India and Mongolia. It alternates between the two countries each year.
• India-Mongolia relations: Mongolia follows a "third neighbour" foreign policy, cultivating ties with democratic nations to balance China and Russia. India established a Strategic Partnership with Mongolia in 2015. India provides military training and assistance. Mongolia is an important source of copper, coal, and rare earths.

GS area: Polity (Constitutional bodies, Federal fiscal relations)

The 16th Finance Commission (FC-XVI) received a new part-time member: T. Rabi Sankar, a former RBI Deputy Governor.

• Constitution date: the 16th Finance Commission was constituted on 31 December 2023.
• Award period: 1 April 2026 to 31 March 2031.
• Powers: the Finance Commission operates with the powers of a Civil Court under the Code of Civil Procedure, 1908, for summoning witnesses and collecting evidence.
• Constitutional basis: Article 280 of the Constitution mandates a Finance Commission every five years. It recommends the share of central taxes to be devolved to states and the grants-in-aid to states from the Centre.
• 15th Finance Commission: chaired by N.K. Singh. Its award period was 2021-26.
• 16th Finance Commission chair: as per public records, Dr. Arvind Panagariya was appointed chair.
• Key tasks: determine vertical devolution (how much of central taxes go to states as a pool) and horizontal distribution (the formula for sharing among states).

A new research technique called MagIC (Magnetic Isolation and Concentration) dramatically improves cryo-EM imaging of dilute biological samples.

• What MagIC does: uses magnetic beads to tag and concentrate target molecules from very dilute samples, then applies the AI-based DuSTER algorithm to filter noise.
• Impact: enables imaging of samples 100 times more dilute than was possible with conventional cryo-EM.
• Cryo-EM: cryo-electron microscopy. A technique for imaging biological molecules (proteins, viruses, enzymes) at near-atomic resolution by rapidly freezing the sample. Won the Nobel Prize in Chemistry in 2017 (Jacques Dubochet, Joachim Frank, Richard Henderson).
• Applications: ultra-dilute biological sample analysis for drug discovery, understanding disease mechanisms, and developing targeted therapies.
• Significance for UPSC: cryo-EM is a standard Science and Technology topic. The 2017 Nobel Prize connection and the applications in drug discovery are examination-worthy hooks.

• World Bank poverty line context: the earlier $2.15 per day line (PPP 2017) was set in 2022. The 2025 revision to $3 (PPP 2021) reflects updated purchasing power parity calculations. India's moderate poverty rate under the $4.20 lower-middle-income threshold is 23.9 per cent (2022-23).
• ICDRI 2025: the International Conference on Disaster Resilient Infrastructure 2025 was held in Europe for the first time. CDRI (Coalition for Disaster Resilient Infrastructure) was launched by India in 2019 and has 46 member countries. Its headquarters is in New Delhi.
• Solar Climate Intervention: Stratospheric Aerosol Injection (SAI) involves spraying sulphur dioxide at 13-20 km altitude to reflect sunlight and cool the planet. Risks include regional climate disruption, ozone layer damage, and acid rain. It is a last-resort geoengineering technique, not an approved intervention. Discussed at climate negotiations as the world struggles to meet Paris Agreement targets.
