1. PESA Act: 25 years of delayed implementation
GS area: Polity, Governance, Society
The Panchayats (Extension to Scheduled Areas) Act 1996 (PESA) completed 25 years in Jharkhand with implementation still critically incomplete.
Enacted: 24 December 1996.
Purpose: Extended the Panchayati Raj framework to areas covered by the Fifth Schedule of the Constitution. Recognised the Gram Sabha as the supreme authority in tribal self-governance.
Rights conferred on Gram Sabha:
Protection and management of customary law and practices.
Control over minor forest produce (tendu leaves, bamboo, other non-timber products).
Authority over land acquisition in the area.
Management of natural resources including water, forests and minerals.
Fifth Schedule: Covers Scheduled Areas in 10 states (Andhra Pradesh, Chhattisgarh, Gujarat, Himachal Pradesh, Jharkhand, Maharashtra, Madhya Pradesh, Odisha, Rajasthan, Telangana).
Gadchiroli success: In Gadchiroli (Maharashtra), federated Gram Sabhas took over management of tendu and bamboo collection, cutting out middlemen. Forest-dependent incomes increased measurably.
Jharkhand failure: State governments repeatedly dilute PESA provisions by not framing state-level rules or by allowing bureaucratic dominance over Gram Sabha decisions.
The gap between PESA's textual rights and its ground-level implementation is the core mains and prelims examination point. The Gram Sabha is legally supreme but institutionally weak.
A policy brief drawing on Nobel laureate James Heckman's research placed early childhood investment at the top of India's spending priorities.
Brain development: 85% of critical brain wiring (neural pathways) is complete by age six. Interventions before this age have disproportionate impact on cognitive and non-cognitive skills.
Heckman Curve: Shows returns to public investment per dollar spent. Early childhood education returns are higher than all subsequent educational interventions combined. The curve slopes downward from infancy through childhood, adolescence and adulthood.
Key gap: ICDS (Integrated Child Development Services, 1975) trained anganwadi workers for nutrition provision, not early pedagogy. The shift to learning-focused early childhood requires retraining and curriculum change.
Key schemes:
Mission POSHAN 2.0: Merged multiple nutrition programmes. Targets severe acute malnutrition, stunting and low birth weight.
Saksham Anganwadi: Upgraded anganwadi centres with improved infrastructure.
NIPUN Bharat: Targets foundational literacy and numeracy by Grade 3.
NEP 2020: Mandates a five-year foundational stage (ages 3 to 8) under a new curricular framework.
The Man Portable Anti-Tank Guided Missile (MPATGM) completed user trials by DRDO.
Type: Third-generation, fire-and-forget missile. The operator does not need to maintain line of sight after launch.
Range: 200 to 4,000 metres.
Guidance: IIR (Imaging Infrared) homing seeker that autonomously tracks the target after lock-on.
Warhead: Tandem HEAT (High Explosive Anti-Tank) for defeating modern reactive armour. The first shaped charge detonates the reactive armour; the second shaped charge penetrates the underlying armour.
Portability: Shoulder-launched, operable by a single soldier.
Significance: Replaces Konkurs imported anti-tank missiles with a fully indigenous system.
PSLV-C62 experienced a third-stage anomaly, the second consecutive PSLV failure after PSLV-C61 in May 2025.
PSLV structure: Four alternating stages.
PS1: Solid core stage (S139 motor).
PS2: Liquid Vikas engine stage.
PS3: Solid stage (S7 motor).
PS4: Liquid stage for orbital insertion precision.
Third stage (PS3) failure: The solid S7 motor is the third stage. A failure here means the upper stages cannot place the satellite in orbit.
Significance of two consecutive failures: PSLV has been India's most reliable rocket with a strong record since 1994. Two consecutive failures are rare and require a failure review panel investigation.
Impact: EOS-N1 (Anvesha) and co-passenger payloads were lost. ISRO's commercial launch manifest is disrupted.
An IIT Madras study found that aerosols intensify winter fog formation over the Indo-Gangetic Plain.
Aerosol definition: Tiny solid or liquid particles suspended in the atmosphere. Sources include vehicle emissions, biomass burning (crop residue), dust and industrial pollutants.
Mechanism: Aerosols act as condensation nuclei. Water vapour condenses onto aerosol particles to form fog droplets. Higher aerosol concentrations mean more, smaller fog droplets that scatter light more effectively, reducing visibility more severely.
North India specifics: Temperature inversions trap aerosols near the surface in winter. The combination of low temperatures (increasing relative humidity) and high aerosol loading from crop burning and vehicle emissions creates severe fog events.
Aviation and road impact: Dense fog causes flight cancellations at Delhi, Lucknow and Varanasi. Multi-vehicle pile-ups on national highways are routine.
Static linkage: Air pollution, meteorology.
6. BHASHINI Samudaye: language AI platform
GS area: Science and Technology, Governance
MeitY launched the BHASHINI Samudaye ecosystem platform under the National Language Translation Mission.
Purpose: Accelerate development and use of AI tools in Indian languages.
BhashaDaan: A citizen crowdsourcing component where volunteers contribute speech, text and translations in Indian languages to build training datasets.
Ethical framework: Data collected with explicit consent; contributors retain some rights over submissions.
Applications: Real-time translation, speech-to-text in multiple Indian languages, accessibility tools for non-English speakers.
National Language Translation Mission (NLTM): Called Bhashini in its operational form. Funded under the Digital India programme.
Static linkage: Language policy, digital inclusion, AI governance.
7. Bannerghatta National Park: ESZ reduction controversy
GS area: Environment, Governance
The Eco-Sensitive Zone (ESZ) of Bannerghatta National Park was reduced in 2020 from 268.9 sq km to 168.64 sq km, opening areas near Bengaluru to real estate development and quarrying.
Location: 22 km south of Bengaluru, in the Anekal hill range, Karnataka.
Status: National Park since 1974. Reserve Forest since 1970.
Ecological role: A vital elephant corridor linking the BR Hills and Sathyamangalam forest complexes. Without this corridor, elephant populations in either forest become genetically isolated.
Suvarnamukhi stream: The primary water source running through the park.
Central Empowered Committee (CEC) recommendation: Restore the 2016 original ESZ boundary of 268.9 sq km.
ESZ definition: A buffer around protected areas where development is regulated. Declared under the Environment (Protection) Act 1986.
Static linkage: Protected area network, wildlife corridors, ESZ.
8. Rajasthan's first organic panchayat
GS area: Agriculture, Governance
Bamanwas Kankar, a panchayat in Rajasthan, received full organic certification, making it the first in the state to eliminate chemical fertilisers and pesticides across all village agriculture.
Implementation: Institutional support provided by COFED (Cooperative Federation) for organic certification and market access.
Why it matters: Organic certification opens premium export markets and provides price premiums domestically. It also demonstrates that at village scale, the transition is economically viable.
Seven hamlets: The panchayat covers seven hamlets, all of which eliminated synthetic inputs.
The US launched the Pax Silica Initiative as an economic security partnership for semiconductor and silicon supply chain security.
Members: Japan, South Korea, Singapore, Netherlands, UK, Israel, UAE and Australia.
Guest partners: Taiwan, EU, Canada and OECD.
India: Invited to join next month. Has not yet formally joined.
Purpose: Coordinate national strategies for semiconductor supply chains, reduce dependence on China and build shared manufacturing capacity.
Relevance for India: India's semiconductor mission (India Semiconductor Mission, ₹76,000 crore) positions the country for membership. Joining would create binding commitments on technology sharing.
Static linkage: India Semiconductor Mission, technology geopolitics.
10. Briefly noted
Greenwald Limit in nuclear fusion: China's EAST reactor achieved 1.3 to 1.65 times the Greenwald Limit (the theoretical plasma density ceiling beyond which tokamak plasma becomes unstable) while maintaining stability. This is a fusion milestone.
Child Marriage in India: NFHS-5 (2019-21): 23% of women aged 20-24 married before 18. The Bal Vivah Mukt Bharat campaign targets elimination by 2030.
