Atmanirbhar Panchayat Programme
Context: Recently, the Ministry of Panchayati Raj launched the Atmanirbhar Panchayat Programme, the SAMARTH Panchayat Portal.
About Atmanirbhar Panchayat Programme
- It is a competitive national challenge initiative under the Ministry of Panchayati Raj that helps Gram and Block Panchayats convert local assets and opportunities into sustainable revenue-generating projects.
- Objective: The programme aims to strengthen the Own Source Revenue (OSR) base of Panchayati Raj Institutions and reduce their dependence on government grants.
- Implementing Body: The programme is implemented by the Ministry of Panchayati Raj, with financing facilitated through PPPs, CSR contributions, scheme convergence and bank finance, with NABARD and HUDCO as institutional partners.
- Salient Features:
-
- Project Scale: It targets 350 projects over four years, comprising 50 projects in the first year and 100 projects annually for the next three years.
- Eligibility: Gram Panchayats with minimum OSR of ₹50 lakh and Block Panchayats with minimum OSR of ₹1 crore, with at least three years of tenure remaining, are eligible; thresholds are relaxed for Special Category States.
- Technical Guidance: The programme provides technical support to develop bankable projects and promotes innovative financing models for sustainable local revenue generation.
About SAMARTH Panchayat Portal
- SAMARTH is a unified, configurable national digital platform designed to strengthen Panchayat finances through technology-enabled management of OSR.
- Objective: To improve the efficiency, transparency and accountability of Panchayat revenue collection by digitising the entire revenue lifecycle.
- Implementing Body: The portal has been developed by the Ministry of Panchayati Raj as a national digital initiative.

Blue Straggler Stars (BSS)
Context: Indian astronomers have discovered a Blue Straggler Star actively forming in the binary system TIC 327546480.
About Blue Straggler Stars (BSS)
- Blue Straggler Stars are unusually hot, bright and massive stars found in old star clusters that appear younger than surrounding stars of similar age.
- Discovery: The BSS was identified in TIC 327546480, a semi-detached binary system located in the old open cluster Collinder 261, approximately 9,500 light-years away.
- Researchers from the Indian Institute of Astrophysics (IIA) collaborated with international astronomers in the study.
- Sources of Data: The researchers combined high-precision light curves from NASA’s TESS (Transiting Exoplanet Survey Satellite) mission with radial velocity measurements from the European Southern Observatory’s Very Large Telescope (VLT), along with X-ray observations.
- Key Features of Blue Straggler Stars
- Stellar Rejuvenation: BSSs appear younger than their surrounding stars because they acquire additional mass and fresh hydrogen fuel, effectively resetting their evolutionary clock.
- Mass Transfer: In TIC 327546480, the less massive companion star overflows its Roche lobe and transfers matter to the BSS, providing direct evidence of active formation through binary mass transfer.
- Rapid Rotation: The BSS rotates rapidly at about 69.55 km/s, likely because the accreted material transfers angular momentum to the star.
- X-Ray Evidence: Strong X-ray emission from the system provides independent evidence that material from the companion is actively being accreted by the BSS.
The discovery offers a rare opportunity to study binary evolution, stellar rejuvenation and the formation of star clusters, helping resolve a long-standing mystery in stellar astrophysics.
‘Unjha Jeera’ and ‘Unjha Fennel
Context: Rajasthan farmers have objected to the GI recognition of ‘Unjha Jeera’ and ‘Unjha Fennel’, arguing that Unjha, Gujarat is primarily a major trading hub rather than a production centre.
Key Objections
- Production vs. Marketing Hub: Farmers argue that a GI tag should identify products whose distinctive qualities are geographically linked to their place of production, whereas Unjha is primarily a major aggregation, grading and trading centre.
- Rajasthan’s Production Role: Rajasthan is a major producer of both spices, with much of the jeera and saunf traded through the Unjha APMC originating from Rajasthan.
- Fear of Price Disadvantage: Farmers fear that the GI tag may allow traders to market Unjha-labelled products as superior, potentially weakening the bargaining power and prices of Rajasthan’s producers.
About GI Tag Certification
- Meaning: A Geographical Indication (GI) tag identifies goods originating from a specific geographical territory whose quality, reputation or characteristics are essentially attributable to that origin.
- Legal Framework: In India, GI protection is governed by the Geographical Indications of Goods (Registration and Protection) Act, 1999, administered through the GI Registry.
- Significance: GI registration prevents unauthorised use of geographical names and helps protect producers, preserve traditional knowledge and enhance product marketability.
