Cost of Convenience: Health Hazards of Digital Tools
Syllabus: E waste
Source: TH
Context: India generated 2.2 million tonnes of e-waste in 2025, becoming the third-largest generator globally after China and the US. Despite formal recycling capacity, more than half of the waste is still processed informally.
About Cost of Convenience: Health Hazards of Digital Tools
India and E-waste Burden:
• India’s e-waste surged 150% since 2017–18, from 0.71 MT to 2.2 MT in 2025.
• 65 cities produce 60% of total e-waste, with hotspots like Seelampur (Delhi), Moradabad (UP), Bhiwandi (Maharashtra).
• Though 322 formal units can process 2.2 MT annually, >50% remains in informal chains of kabadiwalas and scrap dealers.
Health Hazards of E-Waste
• Respiratory Illnesses:
• Open-air burning and acid treatment release fine particulate matter. Eg: 2025 MDPI study found 76–80% of Indian informal e-waste workers suffered chronic bronchitis and asthma.
• Open-air burning and acid treatment release fine particulate matter.
• Eg: 2025 MDPI study found 76–80% of Indian informal e-waste workers suffered chronic bronchitis and asthma.
• Neurological Damage:
• Heavy metals like lead and mercury impair brain development in children. Eg: A 2023 review in Frontiers in Public Health linked blood lead levels ≥5 µg/dL with cognitive decline and behavioral disorders.

• Hazards intersect with poverty, malnutrition, and poor housing, worsening outcomes for urban poor.
• Eg: Informal recycling hubs report higher miscarriages and preterm births (Guiyu, China as global parallel).
Policy Response:
• Strengthened EPR norms – The 2022 Rules tightened Extended Producer Responsibility, making producers accountable for collection and recycling.
• Mandatory registration – Dismantlers and recyclers must be registered to curb illegal, unsafe practices and improve accountability.
• Incentives for formalisation – Policies encourage transition from informal to formal units by offering compliance-linked incentives.
• Persistent gaps – Only 43% of e-waste was formally processed (2023–24); disputes over capped EPR credits hinder effective enforcement.
Way Ahead:
• Formalise informal sector – Train kabadiwalas, provide PPE, healthcare and social security so that livelihoods are protected while ensuring safe recycling practices.
• Strengthen enforcement – Introduce digital tracking, periodic audits and empower Pollution Control Boards to crack down on unsafe, unregistered recycling units.
• Medical surveillance – Organise regular health camps, baseline studies and long-term monitoring in e-waste hotspots to safeguard vulnerable workers and children.
• Promote innovation – Support R&D for affordable, local recycling technologies and create decentralised hubs to reduce transport costs and increase efficiency.
• Awareness building – Integrate e-waste education in school curricula and launch public campaigns to promote responsible disposal among citizens.
Conclusion
India’s digital leap cannot be allowed to create a toxic legacy of disease and degradation. Systemic reforms must combine science, justice, and innovation to safeguard people and ecosystems. Only then can digital empowerment truly align with sustainable and inclusive growth.
The Battlefield and Change
Syllabus: Security
Source: TH
Context: At the Combined Commanders’ Conference 2025 in Kolkata, Prime Minister emphasised moving from service silos to integrated theatre commands to prepare India’s armed forces for future multi-domain wars.
About The Battlefield and Change:
Changing nature of warfare:
• AI and Automation – Artificial intelligence enables faster decision-making and autonomous systems, but increases risks of cyber sabotage and ethical dilemmas.
• Drones and Precision Weapons – Low-cost drones and precision-guided munitions make attacks more lethal and accessible, altering traditional battlefield calculations.
• Cyber & Information Warfare – Wars now extend to digital and psychological domains, where misinformation and hacking can cripple critical infrastructure without a shot fired.
• Two-Front Threat – India must be combat-ready for simultaneous pressure from China and Pakistan, demanding jointness, structural reforms, and tech-driven preparedness.
From coordination to command:
• Theatre commands push – PM of India in 2025 urged shifting from service silos to integrated theatre commands for unified operational command.
• Inter-Services Rules 2025 – Empower commanders with administrative and disciplinary authority to ensure true jointness in field operations.
• Tri-service agencies raised – Cyber, space and special operations wings under HQ IDS boost integrated defence preparedness.
• New modular groups – Units like “Rudra” & “Bhairav” merge infantry, armour, artillery and surveillance for rapid mission-specific deployment.
• Amphibious doctrine – Framework created for land-air-sea synergy, but India still lags China’s mature integrated commands.
Doctrinal and technological evolution:
• Joint doctrines – The 2017 and 2018 doctrines laid basic principles of synergy, now needing modernisation for multi-domain wars.
• Ran Samvad seminar – Stressed building “hybrid warriors” who combine tactical skills with coding, cyber, and information warfare.
• MQ-9B drones – Provide persistent ISR and precision strike, strengthening tri-service employment across borders and seas.
• Rafale-M jets – Enhance carrier aviation, giving Navy strong maritime strike and fleet air defence capacity.
• Akashteer AI network – Integrates Army’s air defence with IAF’s command system, enabling faster and automated responses.
Creating a modern force:
• Integrated Battle Groups – “Rudra” brigades designed to deploy within 12–48 hrs with multi-domain assets for fast response.
• Pralay missile trials – Quasi-ballistic missiles expand India’s land-based theatre strike capability against hardened targets.
• Carrier-centric Navy – Rafale-M stabilises near-term air wings while Navy charts 15-year roadmap for manned & unmanned dominance.
• Civil-military fusion – Strong integration of DRDO, PSUs, private firms and universities into PME will fast-track innovation.
Way forward:
• Gradual theatre commands – Start with limited mandates and expand, balancing inter-service differences with operational needs.
• Standardised systems – Unified data and interface protocols will ensure seamless communication and interoperability.
• Technologist-commanders – PME must embed AI, cyber, coding and tech training into leadership to create adaptive warriors.
• Industrial ecosystem – Rapid prototyping, repeated field trials, and discarding outdated systems will keep the military agile.
Conclusion:
The battlefield of the future will be multi-domain where speed, information, and adaptability matter as much as firepower. For India, achieving true jointness, civil-military fusion, and technological integration is essential to face evolving threats and remain operationally decisive.

Sir Creek
Source: IT
Context: Defence Minister of India warned Pakistan of a decisive response to any misadventure in the Sir Creek sector, citing its growing military build-up in the disputed region.
About Sir Creek:
What it is?
• Sir Creek is a 96-km long tidal estuary, once called Ban Ganga, situated in the Indus River Delta.
• It is a marshy, uninhabited stretch where seawater mixes with river waters, making the terrain unstable and ecologically fragile.
Located in:
• Lies on the India–Pakistan border, separating Kutch region of Gujarat (India) from Sindh province (Pakistan).
• The creek opens into the Arabian Sea, thus directly influencing maritime boundaries and fishing zones of both nations.
Features:
• It is a narrow, muddy, and shifting water channel prone to changes in its course due to tidal activity.
• The region is part of the Indus Delta wetlands, home to migratory birds and marine biodiversity.
• Control over Sir Creek is crucial as it impacts the demarcation of Exclusive Economic Zones (EEZs) and the continental shelf, which determine rights over fishing, oil, and gas exploration.
History of the Dispute:
• The issue dates back to a 1914 resolution between the Government of Bombay (under British India) and the Ruler of Sindh. Pakistan’s claim: The resolution placed the boundary on the eastern bank, giving the entire creek to Sindh (and hence Pakistan after 1947). India’s claim: The resolution invoked the thalweg principle (boundary runs through the middle of the navigable channel), making the border lie mid-stream.
• Pakistan’s claim: The resolution placed the boundary on the eastern bank, giving the entire creek to Sindh (and hence Pakistan after 1947).
• India’s claim: The resolution invoked the thalweg principle (boundary runs through the middle of the navigable channel), making the border lie mid-stream.
• After Partition (1947), Gujarat remained with India, Sindh with Pakistan, making this boundary contested.
• In 1968, an international tribunal settled much of the Rann of Kutch border, but Sir Creek was left unresolved.
