2. Birsa Munda’s birth anniversary
GS paper I: Indian history
Context: Birsa Munda’s birth anniversary is being observed nationwide as part of Janjatiya Gaurav Varsh (2021–2024), marking 150 years of tribal icons and movements. This national observance recognizes for the first time the historic role of tribal leaders in India’s freedom struggle and nation-building. The celebration signifies the country’s shift from past marginalization of tribal narratives to formal, institutional acknowledgment through nationwide commemorations and targeted empowerment missions.
Tribal Freedom Struggles and Their Influence on National Consciousness
- Historic Resistance: Tribal leaders such as Tilka Manjhi, Sidhu and Kanhu Murmu, Tantia Bhil, Rani Gaidinliu, and Veer Narayan Singh spearheaded revolts against British rule, moneylenders, and exploitative zamindars.
- Collective Assertion: These movements demonstrated unity of purpose and resistance across regions, revealing early grassroots-level political consciousness.
- Cultural Protection: Tribal revolts were as much about defending land and cultural identity as they were about challenging colonial and feudal oppression.
Birsa Munda: The Torchbearer of Janjatiya Identity
- Champion of Tribal Rights: Led the Ulgulan (The Great Tumult), demanding freedom from British interference and restoration of traditional land rights.
- Symbol of Pride: Embodied the struggle for dignity, spiritual assertion, and social reform among tribal communities.
- National Recognition: In 2021, his birth anniversary was declared Janjatiya Gaurav Divas, the first national day dedicated exclusively to tribal heritage.
- Enduring Legacy: The Jharkhand movement and the eventual creation of tribal-dominated states like Jharkhand, Chhattisgarh, and Uttarakhand draw inspiration from his ideals.
Contemporary Government Initiatives for Tribal Empowerment
- PM-JANMAN Mission:
- Focuses on holistic development for 75 Particularly Vulnerable Tribal Groups (PVTGs).
- Ensures delivery of essential infrastructure—housing, health, education, drinking water, and connectivity.
- Dhani Aaba Janjatiya Gaurav Ashram Abhiyan:
- Establishes community-level hubs for socio-economic development.
- Boosts local self-governance and collective identity.
- Expansion of Eklavya Model Residential Schools (EMRS):
- 728 schools sanctioned and 479 operational.
- Narrows the educational gap through high-standard, residential schooling for tribal children.
- Tribal Business and Market Support:
- Organizing business conclaves to promote geotagging and marketing of tribal products.
- Enhancing value-chain linkages and entrepreneurship.
Political and Institutional Support for Janjatiya Reforms
- Enhanced Representation: Consistent focus on tribal welfare through dedicated policies and governance structures.
- Preservation of Heritage: Ten tribal freedom fighter museums sanctioned (four inaugurated) to document and honour tribal contributions.
- Prime Ministerial Outreach: The visit to Ulihatu, Birsa Munda’s birthplace, symbolizes national acknowledgment of tribal heritage and historical significance.
Transition from Isolation to Empowered Inclusion
- Institutional Integration: Establishment of the Ministry of Tribal Affairs formalized tribal governance within national policymaking.
- Economic Progress: Infrastructure and livelihood programs under PM-JANMAN and similar schemes enhance connectivity, education, and local employment.
- Cultural Revival: Nationwide celebration of Janjatiya Gaurav Varsh promotes awareness and pride in tribal history and traditions.
Conclusion
Birsa Munda’s ideals continue to guide India’s commitment to justice, dignity, and equitable development for tribal communities. The celebration of Janjatiya Gaurav Varsh and the strengthening of empowerment missions represent a historic shift—from centuries of neglect to structured state-led inclusion—marking a milestone in India’s democratic transformation.
3. Delhi’s air, a wicked problem in need of bold solutions
GS PAPER III-Environmnent and ecology
Context: Delhi’s severe air pollution crisis has worsened again during winter, prompting alarm and urgent calls for policy action and public health protection.
- The article highlights Delhi’s recurring toxic air problems, sources, health dangers, policy failures, and the need for multifaceted, bold solutions to break the cycle
How Bad is the Situation
- AQI routinely exceeds 400 (severe), peaking at 1,200 in Nov 2025, 10-20x WHO safe limits.
- Delhi world’s most polluted city; PM2.5 at 90 µg/m³ in 2024, causing visibility drop to 100m.
- Schools closed, flights delayed; 30M residents face “gas chamber” conditions annually.
- 1.72M air pollution deaths in India (2022), up 38% since 2010; Delhi claims 17K lives/year.
Health Impacts
- 15-20% rise in respiratory diseases; irreversible lung damage in 2.2M children.
- Cardiovascular risks from PM2.5/NO₂; hypertension, COPD, lung cancer up 30% in polluted areas.
- Disrupts hormones/reproduction: irregular cycles, miscarriages, reduced sperm; eye damage 4x higher in rural NCR.
- Vulnerable groups (kids, elderly, chronic patients) face neurological harm, kidney strain; 3/4 households ill.
Economic Impacts
- Reduces life expectancy by 10+ years; healthcare costs strain families and state budgets.
- Disrupts tourism, flights, construction; $100M pollution control budget underutilized (1% spent in 2024).
- Crop burning halts farming; industries face shutdowns under GRAP, costing billions in lost productivity.
- Widens inequality: low-income groups bear brunt without air purifiers or relocation options.
Why is Delhi’s Pollution a Wicked Problem
- No clear boundaries: Transboundary sources like stubble burning from Punjab/Haryana spill into Delhi.
- Conflicting interests: Farmers need quick residue clearance; urbanites demand clean air; politics favors short-term fixes.
- Evolving dynamics: Urban growth, Diwali fireworks, climate change amplify annual spikes unpredictably.
- Politically fraught: Data tampering, inter-state blame; no single authority for holistic enforcement.
Natural Factors Worsening Delhi Air
- Winter inversion traps pollutants in cold, still air, blocking dispersion over northern plains.
- Low winds and dry conditions post-monsoon prevent natural flushing; temperature drops to 5-10°C exacerbate trapping.
- Himalayan foothills create stagnant air bowl, channeling smog from NCR region.
- Climate variability: Erratic rains reduce dilution; dust storms add PM10 in pre-winter months.
Human-Made Factors
- Vehicular emissions: 40% of PM2.5/NO₂ from traffic; 10M+ vehicles in NCR overload roads.
- Stubble burning: 30% pollution spike from crop residue fires in neighboring states (Oct-Nov).
- Industrial/urban sources: Coal power plants, construction dust, waste burning contribute 25% PM.
- Cultural spikes: Diwali firecrackers add barium nitrate; biomass cooking in slums emits indoors/outdoors.
Why Solutions Have Failed
- Reactive GRAP measures (e.g., odd-even, bans) ignore root causes like agriculture; only temporary relief.
- Implementation gaps: Poor enforcement of PUC checks, vehicle bans; VAHAN database outdated.
- Inter-agency conflicts: State-center blame; low budget utilization (e.g., 1% of $100M in 2024).
- Symbolic fixes: “Green” crackers ineffective in mass use; no sustained farmer incentives for alternatives.
Why 2024-2025 Offers a Unique Opportunity
- Revised GRAP (Sep 2024) adds proactive Stage I measures like dust control, EV mandates from Oct 1.
- Air Pollution Mitigation Plan 2025 (launched Jun 3) targets BS-VI/CNG vehicles, mist drones for hotspots.
- Public momentum: Protests, real-time AQI data empower citizens; Supreme Court pushes accountability.
- Global focus: COP30 climate talks highlight India’s hypocrisy; NCAP targets 40% PM reduction by 2026 feasible now.
Global Examples Delhi Must Learn From
- London (1952 Smog): Coal ban post-4K deaths; shifted to gas/electricity, cut PM by 80% via Clean Air Act.
- Beijing (2013 Peak): 5-year plan closed 2.5K factories, odd-even plates; PM2.5 fell 35% by 2017 via regional controls.
- Mexico City (1980s Crisis): Child health studies built support for fuel switch, public transit; AQI improved 50% with multi-agency plan.
- Los Angeles (1940s Smog): Vehicle emission standards, catalytic converters; reduced ozone 75% through federal-state enforcement.
What Should Delhi Do Now
- Enforce GRAP III fully: Ban BS-III/IV vehicles, construction; hybrid schools up to Class 5.
- Boost public transit: Expand Metro/EVs; congestion pricing like London to cut traffic 30%.
- Farmer incentives: Subsidize machinery for stubble alternatives; regional task force with Punjab.
- Citizen action: School campaigns, real-time data apps; ban waste burning, promote antioxidants/steam inhalation.
4. Astronomer’s spot coronal mass ejection on another star for first time
GS paper III-science and technology
Context: Astronomers have, for the first time, detected a coronal mass ejection (CME) on a star other than the Sun—specifically on red dwarf star stKM 1-1262, 133 light-years away
What are Coronal Mass Ejections?
- CMEs are massive eruptions of plasma and magnetic field from a star’s corona, which can affect satellites, power grids, and cause auroras on planets with a magnetic field.
Why is This Discovery Special?
- It is the first confirmed detection of CME radio signals from another star, solving a major technical challenge in stellar astronomy.
- The detected CME was at least 10,000 times more violent than solar CMEs.
How Was This CME Discovered?
- The discovery used radio signals captured by Europe’s LOFAR telescope network since 2016, and a 2022 data review spotted the event on May 16, 2016.
- Researchers set up a special data processing system to analyze background stellar activity.
Why is This CME Extraordinary?
- The detected explosion lasted only one minute yet was staggeringly powerful—capable of stripping atmospheres from planets.
- Red dwarfs like stKM 1-1262 show much more frequent and violent CME activity compared to the Sun.
Implications for Exoplanet Habitability
- CMEs from red dwarfs may destroy atmospheres of nearby planets, making their habitability unlikely even if the planet is Earth-sized and in the habitable zone.
- This raises major questions about the prospects of life around active stars, as frequent CMEs create hostile environments.
Why Mention Auroras?
- Auroras are visual evidence of CME effects on planets; the article drew an analogy with strong solar storms causing auroras on Earth to explain potential impacts on exoplanets.
Conclusion
- First radio CME detection on another star marks a leap in astrophysics and exoplanet studies.
- Red dwarfs’ violent outbursts challenge the habitability of planets in their orbits, highlighting the need to reassess exoplanet life prospects.
5. Flexible inflation targeting, a good balance
GS PAPER III-Indian economy
Context: The FIT framework is undergoing its second major review since 2016, marking a critical juncture for India’s monetary policy.
- The RBI has released an extensive research paper featuring long-term empirical data on inflation and growth since 1991.
- India’s inflation recently hovered near the upper tolerance limit, prompting discussions on whether the central 4% target should be maintained or adjusted.
- Decisions from this review will influence India’s monetary policy autonomy, fiscal-monetary coordination, and economic growth strategies for the coming decade.
Importance of Inflation Control in Monetary Policy
- Inflation as a Regressive Tax: High inflation disproportionately affects low-income households by eroding purchasing power.
- Avoiding Resource Misallocation: Elevated inflation creates economic uncertainty, leading to volatile investment and inefficient resource use.
- Historical Context: The Chakravarty Committee (1985) recommended a 5% inflation target, but evolving economic contexts necessitate periodic reassessment.
- Institutional Evolution: Since 1994, RBI has gained autonomy, culminating in the FIT framework’s statutory backing for price stability in 2016.
Structure of India’s FIT Framework
- Inflation Target Band: Set at 4% with a ± 2% tolerance, balancing flexibility and anchoring inflation expectations.
- Headline Inflation as the Focus: Prioritizes overall price stability including supply-side shocks (especially food), aligning with global standards.
- Proven Stability: Despite various shocks, inflation has largely stayed within the band, reflecting RBI’s growing policy credibility.
- Adaptive Framework: Institutional mechanisms continue evolving to address the complexity of India’s economy.
Targeting Headline vs. Core Inflation
- Headline inflation captures critical supply shocks like food and fuel price changes that deeply impact households.
- Core inflation, excluding volatile items, helps identify underlying inflation trends but may understate the inflation burden on common citizens.
- Empirical insights show general inflation rises with monetary expansion (liquidity-driven), while relative price changes without liquidity growth do not sustain inflation.
Insights from Long-term Inflation-Growth Data
- A quadratic relationship between inflation and growth (1991-2023) shows growth increases with inflation up to around 4%, but declines beyond that.
- This suggests an optimal inflation target near 4%.
- Inflation beyond this harms growth, especially alongside supply constraints, fiscal pressures, and global economic risks.
Flexibility of the Inflation Band
- The current ± 2% band has allowed India to respond to shocks flexibly.
- However, persistently operating near the upper band risks undermining RBI’s credibility.
- The framework avoids past pitfalls of fiscal dominance and automatic monetization, preserving monetary policy independence.
Factors Defining an Acceptable Inflation Level
- Phillips Curve dynamics suggest higher-income countries tolerate marginally higher inflation.
- RBI’s data supports an inflation target near 4% for India’s middle-income status and vulnerabilities.
- Supply-side shocks, climate impact, and imported inflation require strong expectations management to avoid wage-price spirals.
Conclusion
India’s FIT framework has successfully anchored inflation expectations and preserved RBI’s autonomy. Empirical evidence reaffirms 4% as the optimal target amid evolving economic realities. The upcoming review must ensure the framework continues to balance flexibility with credibility, strengthen monetary-fiscal coordination, and enhance resilience to supply shocks, supporting steady growth over the next decade.
