MoTA Launches Largest Tribal Empowerment Campaign – DhartiAaba Janbhagidari Abhiyan

Context and Vision

• Initiative Name: Dharti Aaba Janbhagidari Abhiyan.
• Occasion: Under the Janjatiya Gaurav Varsh to honour tribal legacy and ensure inclusive delivery.
• Vision Alignment: Reflects PM Narendra Modi’s vision of Antyodaya, Janbhagidari, and Viksit Bharat.

Relevance : GS 1(Society ) ,GS 2(Governance)

Scale and Coverage

• Covers 549 tribal-dominated districts.
• Includes 207 Particularly Vulnerable Tribal Group (PVTG) districts.
• Outreach to over 1 lakh villages and habitations.
• Covers 2900+ blocks nationwide.
• Flagship drive runs from 15th to 30th June 2025.

Key Objectives

• Ensure benefit saturation—no eligible tribal household left out.
• Promote last-mile delivery of welfare schemes.
• Foster participatory governance throughJanbhagidari.
• Deliver not just services but also dignity and self-respect.

Delivery Mechanism

• Camp-based outreach model at village and habitation level.
• Coordinated by District Administrations and supported by:
  • Panchayati Raj Institutions
  • Community leaders
  • Grassroots workers
• Over 125 District Magistrates/Deputy Commissioners have started pre-campaign awareness and mobilization.

Schemes and Services Delivered

• Aadhaar card enrollment and updates.
• Ayushman Bharat health card issuance.
• Opening of Jan Dhan Yojana bank accounts.
• Enrollment under PM-Kisan Yojana.
• Access to pension schemes and scholarships.
• Enrollments under insurance schemes, skill training, and livelihood programs.

Governance Model

• Convergence-based governance involving multiple ministries.
• Emphasis on community-led development and stakeholder collaboration.
• Seen as a replicable model for future inclusive policy implementation.

Symbolic Importance

• Pays tribute to tribal heritage, culture, and historical contributions.
• Named after Dharti Aaba (Birsa Munda), a revered tribal freedom fighter.
• Enhances visibility and inclusion of tribal communities in nation-building.

Relevance

• Aligned with goals under PM-JANMAN and DAJGUA (Dharti Aaba Janjatiya Gram Utkarsh Abhiyan).
• Marks a paradigm shift in tribal welfare from demand-based to saturation-based delivery.

DRDO & IIT Delhi demonstrate Quantum Entanglement-Based Free-Space Quantum Secure Communication over more than 1 km distance

Overview and Milestone

• Event: Successful demonstration of quantum entanglement-based free-space quantum secure communication over >1 km distance.
• Partners: DRDO’s Directorate of Futuristic Technology Management (DFTM) and IIT Delhi under the DRDO-Industry-Academia Centre of Excellence (DIA-CoE).
• Significance: Marks India’s entry into a new quantum era; termed a game-changer in future warfare by Defence Minister.

Relevance : GS 3(Science and Technology)

Technical Achievements

• Communication Medium: Free-space optical link (no fiber required).
• Distance Covered: Over 1 km on the IIT Delhi campus.
• Secure Key Rate: ~240 bits per second.
• Quantum Bit Error Rate (QBER): Less than 7%.
• Method Used: Entanglement-assisted Quantum Key Distribution (QKD).

Advantages of Entanglement-Based QKD

• Security: Intrinsically secure—even if devices are faulty or compromised.
• Eavesdropper Detection: Any interception disturbs the quantum state, allowing for detection.
• Superior to prepare-and-measure QKD in robustness and integrity.
• Enables unbreakable encryption—a potential paradigm shift in data security.

Strategic Applications

• Dual-use technology: civil and military.
• Use-cases include:
  • Defence and military communication
  • Finance sector data protection
  • Telecom infrastructure security
  • Critical infrastructure and national security
• Paves way for quantum networks and future quantum internet.

Logistical and Infrastructure Benefits

• Free-space QKD avoids costly and disruptive fiber laying—ideal for urban or difficult terrains.
• Test-bed proves potential for real-time deployment in varying conditions.

Earlier Achievements & Legacy

• 2022: Intercity QKD link between Vindhyachal and Prayagraj using underground fiber.
• 2024: 100 km quantum key distribution via optical fiber (DRDO-IIT Delhi).
• This current demo builds on past successes and demonstrates scalable potential.

Institutional and National Support

• Developed under 15 DRDO DIA-CoEs in IITs, IISc, and other institutions.
• Aimed at indigenous development of cutting-edge defence technologies.

Relevance

• Aligns with India’s National Quantum Mission and Atmanirbhar Bharat in frontier tech.
• Establishes a foundation for future warfare readiness in quantum cybersecurity.
• Reinforces India’s ambition to be a global leader in quantum communication.
