India Launches Largest-Ever Tribal Empowerment Campaign — DhartiAabaJanbhagidari Abhiyan (DAJA)

Context & Significance

• Largest tribal outreach campaign in independent India, launched by the Ministry of Tribal Affairs.
• Honours Birsa Munda (Dharti Aaba) as a symbol of tribal pride under Janjatiya Gaurav Varsh.
• Reflects the PM’s vision of Sabka Saath, Sabka Vikas, Sabka Vishwas, Sabka Prayas.

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

Scale & Coverage

• Duration: 15 June to 15 July 2025.
• Covers 1 lakh+ tribal villages/PVTG habitations across 550+ districts in 31 States/UTs.
• Aims to reach over 5.5 crore tribal citizens.

Major Outcomes (First 9 Days)

• 53 lakh+ tribal citizens reached through 22,000+ camps.
• Aadhaar enrolments: 1.38 lakh+
• Ayushman Bharat cards issued: 1.68 lakh+
• PM-Kisan registration: 46,000+
• PM Ujjwala Yojana enrolments: 22,000+
• Jan Dhan accounts opened: 32,000+

Key Services Delivered

• Social security: Pensions, PM-JDY, Ayushman cards.
• Livelihood: PM-Kisan, start-up support.
• Legal & Land rights: FRA claim assistance.
• Nutrition & Health: Focus on millets and maternal nutrition.
• Cultural revival: Tribal art, music, and cuisine showcased.

Five Pillars of DAJA Governance

1. Janbhagidari – Tribal community-led implementation.
2. Saturation – 100% coverage of eligible households.
3. Cultural Inclusion – Use of tribal languages, art.
4. Convergence – Ministries, CSOs, youth working together.
5. Last-Mile Delivery – Focus on remote and PVTG areas.

State-Level Highlights

• Ladakh: Focus on millet-based tribal nutrition (FM visit).
• Assam: CM flagged it as a new tribal development era.
• Maharashtra: Entrepreneurship & self-reliance focus.
• Kerala: Tribal conclave for collaborative planning.
• AP & MP: Inclusion of forest-dwelling and vulnerable groups.

Mobilisation and Participation

• 3,000+ blocks, 700+ tribal communities, 75 PVTGs.
• Active support from MY Bharat, NSS, students, and CSOs.
• Pan-India cultural celebrations: cuisine, dances, crafts.

Vision & Impact

• A step toward inclusive, participatory governance.
• Sets a new benchmark in tribal-centric service delivery.
• Seen as a grassroots revolution for dignity and identity.

A new innovation cleans water with the help of Sunlight, Vibration and Artificial Intelligence (AI), enables Bio-degradable, Eco-friendly and Low-cost Technology

Context & Innovation Overview

• A new biodegradable, eco-friendly, low-cost water purification system developed by INST Mohali under DST.
• Targets industrial dye pollutants like Methylene Blue and Congo Red in wastewater.
• Combines sunlight, mechanical vibrations, and Artificial Intelligence (AI) — a triple-layered sustainable solution.

Relevance : GS 3(Science and Technology,Environment – Pollution)

The Technology Explained

• Core structure: 3D-printed scaffold using Polylactic Acid (PLA) — a biodegradable polymer.
• Catalyst: Bismuth Ferrite (BiFeO₃) coated on PLA for piezo-photocatalysis.
• Principle:
  • Photocatalysis: Sunlight activates BiFeO₃ to break down pollutants.
  • Piezocatalysis: Gentle vibrations trigger the catalyst — works even on cloudy days.
• Result: Efficient pollutant degradation using solar + mechanical energy.

AI-Driven Smart Efficiency

• Machine learning models (e.g. Artificial Neural Networks) trained to:
  • Predict system performance across conditions.
  • Achieve up to 99% accuracy in predictions.
  • Help optimize real-world application and scalability.

Performance Highlights

• Removed 98.9% of Congo Red and 74.3% of Methylene Blue from wastewater.
• Outperformed many conventional high-cost water treatment systems.
• Completely avoids hazardous chemicals or energy-intensive techniques.

Environmental & Industrial Relevance

• Eco-friendly & reusable: Made of biodegradable PLA.
• Low-cost & scalable: Accessible to both industries and rural communities.
• Fossil fuel-free: Operates on renewable solar and mechanical energy.

Sustainable Development Implications

• Addresses SDG 6: Clean Water and Sanitation.
• Also supports SDG 9 (Innovation), SDG 12 (Responsible Consumption), and SDG 13 (Climate Action).
• Ideal for circular economy models in industries like textiles, pharmaceuticals.
