  • [2nd December 2025] The Hindu OpED: The new action plan on AMR needs a shot in the arm

    PYQ Relevance

    [UPSC 2014] Can overuse and free availability of antibiotics without Doctor’s prescription, be contributors to the emergence of drug-resistant diseases in India? What are the available mechanisms for monitoring and control? Critically discuss the various issues involved.

    Linkage: This PYQ directly mirrors the article’s focus on antibiotic misuse, OTC access, and weak regulatory control driving AMR. It lets you use NAP-AMR 2.0 to show gaps in surveillance, stewardship, and One Health governance, exactly what the exam tests.

    Mentor’s Comment

    AMR is now a major threat to India’s health, food systems, and environment. Resistance has moved beyond hospitals into water, soil, and livestock. NAP-AMR 2.0 is timely and shows a stronger, more accountable approach. This analysis helps you clearly understand what worked, what failed, and what must change.It also builds GS2 and GS3 depth through governance, science, environment, and One Health linkages.

    Introduction

    India has released its National Action Plan on Antimicrobial Resistance (NAP-AMR 2.0) for 2025-29, signalling a renewed commitment to containing AMR, a challenge that affects human health, livestock, agriculture, the environment, and food systems. Unlike the first plan (2017), which saw uneven adoption across States, the second plan attempts structural reform through higher accountability, stronger surveillance, private-sector engagement, multi-departmental integration and One Health alignment.

    Why in the news?

    The launch of NAP-AMR 2.0 marks a significant turning point because AMR has now expanded beyond hospitals into soil, water, livestock, markets and food systems, making it a full-spectrum health and environmental challenge. 

    How did the first NAP-AMR evolve and where did it fall short?

    1. Significant early progress: Brought AMR into national consciousness, encouraged multi-sectoral participation, improved laboratory networks, and strengthened stewardship.
    2. One Health recognition: Placed AMR within the interface of human health, animals and environment.
    3. State-level stagnation: Most States undertook only individual activities; only a few (Kerala, MP, Delhi, AP, Gujarat, Sikkim, Punjab) created formal AMR action plans.
    4. Weak institutional execution: Multisectoral One Health structures were missing in most States.
    5. Uneven governance: Human health, veterinary systems, pharmaceuticals and waste management lie under different jurisdictions, causing weak coordination.
    6. Monitoring deficiencies: Surveillance, regulatory oversight, environmental contamination monitoring and antibiotic stewardship remained fragmented.

    What makes NAP-AMR 2.0 more mature and implementation-focused?

    1. Shift to national priorities: Moves beyond intent; outlines clear responsibilities across levels of governance.
    2. Private sector engagement: Recognises that a major share of India’s health care and veterinary services is provided privately.
    3. Scientific strategy: Emphasises innovation, rapid diagnostics, alternatives to antibiotics, and improved environmental monitoring.
    4. One Health deepening: Stronger coordination across food safety, waste management, agriculture, environment and human/animal health.

    What new governance mechanisms does the NAP-AMR 2.0 introduce?

    1. Higher accountability: Greater role for national supervision through a dedicated Coordination and Monitoring Committee.
    2. State-level innovation: Recommends every State establish a One Health inter-ministerial AMR committee, along with State AMR cells.
    3. Integrated reporting framework: Aligns State reporting with national structures for uniform monitoring.
    4. Technical backbone: Calls for a national follow-up mechanism and a multi-departmental coordinating structure.

    Where do administrative and operational gaps persist?

    1. Funding limitations: NITI Aayog’s earlier financial grant-based system did not generate adequate incentives.
    2. Weak incentive design: No system for rewarding State performance or penalising poor progress.
    3. Fragmented responsibility: Human health, veterinary systems, agriculture, pharmaceuticals and waste sectors work under separate ministries and State departments.
    4. Lack of real-time accountability: No statutory notification requiring States to inform the Centre of AMR progress.
    5. Dependence on central push: States often wait for Union-level initiatives rather than proactively building AMR infrastructure.

    What financial and institutional reforms does the article highlight as essential?

    1. Mandatory funding channels: Conditional grants through the National Health Mission (NHM) for surveillance and laboratory systems.
    2. Administrative energy: Once funding becomes compulsory, States respond faster.
    3. Scientific backbone: Need for a sustainable, long-term national centre for AMR control and accountability.
    4. International relevance: Without a Centre-backed national AMR programme, India cannot engage in meaningful global AMR governance.

    Conclusion

    The NAP-AMR 2.0 offers an opportunity to anchor India’s AMR response on a stronger scientific and institutional foundation. But success will require coordinated State participation, financial backing, and accountable governance, not just policy intention. A central AMR Centre, integrated surveillance, and enforceable incentives could finally convert national plans into ground-level action across health systems, veterinary services, agriculture, food safety and environmental management.

  • Why does India need bioremidiation

    Introduction

    Bioremediation uses microorganisms such as bacteria, fungi, algae, and plants to break down toxic pollutants like pesticides, plastics, heavy metals, and industrial chemicals into harmless by-products. With India experiencing severe air, water, and soil contamination, bioremediation provides a scalable and sustainable pathway to clean ecosystems. At the same time it will  generate opportunities in biotechnology and environmental consulting.

    What Is Driving India Toward Bioremediation?

    1. Rapid industrialisation: Intensifies contamination of air, water, and land, increasing demand for cost-effective clean-up solutions.
    2. High pollution load: Rivers continue to receive sewage and industrial effluents daily, causing persistent ecological and health risks.
    3. Limitations of traditional clean-up: Conventional methods are expensive, energy-intensive, and often shift pollutants to secondary waste streams.
    4. Biological advantage: Indigenous and extremophile microbes adapted to local temperatures, salinity, and soil conditions perform better than imported strains.

    How Do Different Types of Bioremediation Work?

    1. In situ bioremediation: Direct treatment at the contaminated site (e.g., bacteria sprayed on oil spills or contaminated soil treated on location).
    2. Ex situ bioremediation: Removal and controlled treatment of polluted soil or water in bioreactors or treatment facilities before returning it.
    3. Combination with biotechnology: Genetically modified microbes designed to degrade complex pollutants like plastics or toxins offer enhanced efficiency.

    How Is India Using Bioremediation Today?

    1. Government-supported pilot projects: DBT supports several programmes through its Clean Technology Programme, linking universities, research institutions, and industries.
    2. CSIR-National Environmental Engineering Research Institute initiatives: Mandate to develop and implement bioremediation solutions; contributes to policymaking.
    3. Indian Institute of Technology experiments: Development of microbial synthesised compounds to mop up oil spills and identify bacteria suitable for soil restoration.
    4. Emerging startups: Firms like Biotech Consortium India Limited (BCIL) and Ecominr India offer soil and water microbial solutions.

    What Are Other Countries Doing?

    1. Japan: Integrates microbial and plant-based systems into municipal solid waste strategy.
    2. European Union: Funds cross-country projects to remove toxins, clean up oil spills, and restore mining sites.
    3. China: Makes bioremediation a priority under soil pollution control frameworks and uses genetically improved bacteria for industrial waste.

    What Are the Risks and Challenges?

    1. Environmental risks: Introduction of genetically modified organisms must be strictly monitored to prevent unintended ecological effects.
    2. Lack of unified standards: Absence of national bioremediation protocols, biosafety guidelines, certification systems.
    3. Knowledge and skill gaps: Limited trained personnel, weak microbial testing frameworks, and poor site assessment capacity.
    4. Public scepticism: Low awareness about microbes as environmental allies may slow adoption.

    What Should India Do Next?

    1. Standard-development: Develop national protocols for microbial applications and bioremediation safety.
    2. Regional bioremediation hubs: Link universities, startups, and industries for field testing and faster scale-up.
    3. Government integration: Align bioremediation with Namami Gange, Swachh Bharat Mission, and industrial clean-up mandates.
    4. Public engagement: Raise awareness about biological solutions to restore trust in microbial technologies.

    Conclusion

    Bioremediation presents India with a scalable, sustainable, and scientifically grounded pathway to address its massive environmental burdens. While global examples offer templates for success, India must create strong regulatory frameworks, biosafety standards, and capacity-building ecosystems. Integrating microbes with national missions and industrial compliances can transform bioremediation from pilot projects into mainstream environmental governance.

    PYQ Relevance

    [UPSC 2018] What are the impediments in disposing of the huge quantities of discarded solid wastes which are continuously being generated? How do we remove safely the toxic wastes that have been accumulating in our habitable environment?

  • Sleep Apnea & Parkinson’s Disease 

    Why in the News?

    • A new study published in JAMA Neurology (Nov 24, 2025) found that untreated Obstructive Sleep Apnea (OSA) can nearly double the risk of developing Parkinson’s disease.
    • The study analysed 11 million+ U.S. military veterans’ medical records (1999–2022).
    • Use of CPAP (Continuous Positive Airway Pressure) significantly reduces the elevated risk, making sleep quality a potential neuroprotective factor.

    Key Findings

    • Untreated OSA → ~2× higher likelihood of developing Parkinson’s.
    • CPAP therapy helps maintain oxygen levels → reduces neurodegeneration risk.
    • Repeated oxygen drops during sleep may lead to long-term neuronal stress.
    • Parkinson’s disease risk increases naturally with age, especially >60 years, but untreated OSA further elevates vulnerability.

    About Parkinson’s Disease 

    • A progressive neurodegenerative disorder affecting movement.
    • Caused by loss of dopaminergic neurons in the substantia nigra.
    • Symptoms: tremors, rigidity, bradykinesia, cognitive decline (late stages).
    • No cure; treatments focus on symptom management.

    Prelims Pointers

    • New association identified: OSA ↔ Parkinson’s disease risk.
    • Published in JAMA Neurology.
    • Largest dataset used for this linkage: 11 million veterans.
    • CPAP is not just a sleep device—it may offer neuroprotection.
    • Chronic intermittent hypoxia implicated in neurodegeneration.
    Excessive release of the pollutant carbon monoxide (CO) into the air may produce a condition in which oxygen supply in the human body decreases. What causes this condition? (2010)

    (a) When inhaled into the human body CO is converted into CO2

    (b) The inhaled CO has much higher affinity for haemoglobin as compared to oxygen

    (c) The inhaled CO destroys the chemical structure of haemoglobin

    (d) The inhaled CO adversely affects the respiratory centre in the brain

    This PYQ is chosen because the core pathological connection linking Sleep Apnea and Parkinson’s disease is the concept of chronic oxygen deprivation (Hypoxia) and its neurodegenerative impact.

  • Overcoming resistance: On the National Action Plan on Antimicrobial Resistance (2025–29)

    Introduction

    The Government has introduced the second iteration of the National Action Plan on Antimicrobial Resistance (NAP-AMR) in response to escalating resistance to antibiotics across sectors. While version 1 generated marginal gains and placed AMR on India’s health agenda, its sluggish implementation led to persistent misuse of antibiotics, weak state collaboration, and rising resistance. New evidence, including the 2023 WHO Global Antibiotic Resistance Surveillance report, confirms the urgency for renewed stewardship and a strengthened One Health strategy.

    Why in the News?

     India has launched Version 2 of the National Action Plan on AMR amid alarming data that in 2023, one in three bacterial infections in India showed resistance to commonly used antibiotics, against one in six globally. The spike comes despite NAP-AMR (2017–21), revealing that implementation, not intent, is the major roadblock. The new plan is a crucial attempt to arrest a humongous health, veterinary and environmental crisis before last-line antibiotics become fully ineffective.

    Why did Version 1 of NAP-AMR fall short?

    1. Sluggish implementation: Raised the profile of AMR nationally but failed to translate into coordinated ground-level action.
    2. Weak state participation: Only a few states formulated policies; Kerala alone implemented effectively, registering a slight drop in AMR levels.
    3. Narrow ecosystem focus: Neglect of veterinary, environment, agriculture and aquaculture vectors.
    4. Enforcement gaps: Despite a ban on Colistin as a growth promoter in the husbandry sector, misuse continued in varying degrees.

    How serious is AMR in India today?

    1. High disease burden: High infectious disease load increases antibiotic exposure and accelerates resistance.
    2. Overuse and misuse: Indiscriminate use in healthcare and self-medication remain widespread.
    3. Critical pathogens advancing: E. coli and Klebsiella pneumoniae show high resistance to critical antibiotics, rendering last-line drugs ineffective.

    Why has AMR become a multi-sectoral challenge?

    1. Agriculture & husbandry: Growth promoters and preventive antibiotic usage fuel microbial resistance.
    2. Veterinary medicine: Improper prescription and uncontrolled access to antibiotics.
    3. Soil & water contamination: Antibiotic residues affect ecosystems and re-enter human food chains.
    4. Aquaculture & food processing: Residues facilitate community-level resistance.

    Why is One Health no longer optional?

    1. Integrates human, animal and environmental health to handle widespread resistance emerging across the food chain and biosphere.
    2. Breaks inter-sectoral silos to ensure synchronised surveillance and regulation.
    3. Guides community-level resistance mitigation, not just tertiary hospitals.

    What must Version 2 achieve to succeed?

    1. Strong antibiotics stewardship programmes across community and hospital settings.
    2. Reliable nationwide surveillance network beyond pandemic-led laboratory expansion.
    3. State partnership and compliance mechanisms rather than voluntary policy uptake.
    4. Accountability measures for misuse in human healthcare, veterinary practice and agriculture.

    Conclusion

    India stands at a critical point where policy intent must translate into enforceable implementation. The success of NAP-AMR (Version 2) depends on strong stewardship, inter-state coordination, and an uncompromising One Health approach. Without systemic commitment, antibiotic resistance risks becoming the defining public health disaster of the decade.

    Value Addition

    What is AMR? 

    • Antimicrobial Resistance (AMR) refers to a biological phenomenon in which microorganisms such as bacteria, viruses, fungi, and parasites evolve to resist the action of antimicrobial drugs. As a result, standard treatments become ineffective, infections persist, and the risk of spread, severe illness, and mortality increases.

    India AMR data cue:

    • WHO Global Antibiotic Resistance Surveillance Report (2023): 1 in 3 bacterial infections in India resistant to commonly used antibiotics, compared to 1 in 6 globally.

    Kerala as a Model State 

    • Kerala is often cited as the only state that implemented its state-level action plan on AMR effectively enough to show measurable impact.
    • Key success factors:
      • Strong state-led antibiotic stewardship programme
      • Mandatory prescription audits and regulation of over-the-counter sales
      • Hospital-level AMR surveillance linked to community-level action
      • Training of medical and veterinary practitioners
      • Public awareness + behavioural campaigns

  • Pharmacogenomics: reading genes to tailor prescriptions for individuals

    Why In The News?

    Pharmacogenomics is transforming healthcare by showing how genetic differences affect individual drug responses. This breakthrough emerging technology is replacing traditional “start low, go slow” trial-and-error prescribing with personalised, precision-based treatment that improves effectiveness and reduces harmful reactions.

    1) What is Pharmacogenomics?

    • Definition & Purpose: Studies how genetic variations affect drug response, determining whether a drug will be effective, ineffective, or harmful.
    • Role of Enzymes: Differences in drug-metabolising enzymes, especially the CYP450 family, impact the metabolism of ~75% of common drugs.
    • Metaboliser Phenotypes:
      • Poor Metaboliser: Low enzyme activity → toxic drug buildup at standard doses.
      • Ultrarapid Metaboliser: High enzyme activity → reduced therapeutic benefit.
    • Widespread Variants: About 90% of people carry at least one actionable pharmacogenetic variant.
    • Clinical Impact: Genetic factors significantly contribute to adverse drug reactions (ADRs), a major cause of hospitalisation and death in developed nations.

    2) Understanding the Problem in Traditional Prescribing:

    • Traditional Approach – “Start Low, Go Slow”: Reflects the challenge that the same drug and dose can heal one patient but harm another.
    • Population-Based Prescribing: For decades, medications were prescribed based on population averages, leading to trial-and-error treatment.
    • Shift Toward Precision: Pharmacogenomics is transforming this approach by showing how genes influence drug response, moving from guesswork to precision.

    3) Real-World Applications:

    • Warfarin Dosing:
      • Variants in CYP2C9 and VKORC1 explain ~50% of dose variation.
      • Genetic-guided dosing reduces bleeding risk and allows faster achievement of therapeutic levels.
    • Clopidogrel Activation:
      • Requires CYP2C19 for activation.
      • CYP2C19*2 variants (25–30%) → poor activation → higher risk of stent thrombosis.
      • CPIC 2022 guidelines recommend alternatives for poor metabolisers.
    • Psychiatry:
      • Many antidepressants/antipsychotics rely on CYP2D6 and CYP2C19.
      • Testing reduces side effects, improves symptom control, and lowers costs.
    • Oncology: Rapid progress in using genetic markers to personalise cancer treatment.

    4) Economic Considerations:

    • Cost Reduction: Genetic test prices have dropped from thousands to $200-500 for large panels.
    • Cost–Effectiveness:
      • Testing prevents adverse events and improves outcomes, proving cost-effective, especially in chronic diseases.
    • Evaluation Framework: Value depends on factors such as severity of side-effects, frequency of variants, availability of alternative drugs, and variability in clinical settings.
    • Preventive Value: Avoiding even one serious ADR can offset the cost of testing many patients.

    5) Implementation Challenges:

    • Provider Knowledge Gaps: Most clinicians lack training in pharmacogenomics, making interpretation difficult.
    • Infrastructure Limitations: Electronic health records often lack tools to integrate genetic data into prescribing workflows.
    • Reimbursement Issues: Insurance coverage remains inconsistent, creating hesitation.
    • Regulatory Complexity:
      • Over 100 FDA drug labels include pharmacogenomic information.
      • Some provide actionable guidance; others are only informative.
    • Cultural & Institutional Barriers: Requires changes in clinical culture, administrative support, and trained champions to lead adoption.

    6) The Path Forward:

    • Pre-emptive Testing: Future lies in obtaining genetic profiles before medications are needed, enabling lifelong personalised prescribing.
    • Fundamental Shift: Moves healthcare from population-based to individualised, from reactive to proactive, and from trial-and-error to precision medication.
    • Genomic Insight: Our genes guide our prescriptions-pharmacogenomics teaches us how to read this biological roadmap.
    [UPSC 2023] ‘Aerial metagenomics’ best refers to which one of the following situations?

    Options: (a) Collecting DNA samples from air in a habitat at one go*

    (b) Understanding the genetic makeup of avian species of a habitat

    (c) Using air-borne devices to collect blood samples from moving animals

    (d) Sending drones to inaccessible areas to collect plant and animal samples from land surfaces and water bodies

  • Agentic AI: Tech’s newest buzzword

    Introduction

    Agentic AI refers to a new class of artificial intelligence systems capable of executing multistep tasks, adapting to processes, and performing actions independently rather than merely responding to prompts. The term has witnessed a rapid surge in public and industry attention, driven by new academic reports and its promise of automating complex workflows. The development marks a notable shift from conventional chatbots that were largely conversational and instruction-bound.

    2. Application in Online Services: Includes personal finance assistance, bill interpretation, dispute resolution, or travel booking using card data.
    3. Complex Task Automation: Involves computer access and stepwise execution of guidelines for high-level objectives.

    What Is Driving Industry Optimism?

    1. Workflow Automation Promise: Amazon sees agentic systems as key to automating cloud operations and enterprise-level tasks.
    2. Operational Transformation: Viewed as one of the biggest AI evolutions since early generative models.
    3. Security Applications: Potential as “personal shields” against spam, fraud, and phishing by acting on email and digital data.

    What Are The Concerns or Limitations?

    1. Marketing Hype vs Utility: The term is being debated due to its sudden popularity and vague boundaries.
    2. Lack of True Autonomy: Systems act within training limits despite appearing highly capable.
    3. Ethical and Trust Issues: The blending of autonomous actions with sensitive tasks (finance/computers) raises oversight concerns.

    Conclusion

    Agentic AI represents a shift from conversational to autonomous process-executing systems.

  • What are UNESCO new guidelines for the use of neurotechnology

    Introduction

    Neurotechnology includes devices and procedures that access, assess, or act upon neural systems. Earlier limited to health care, it now merges neuroscience, AI, computing, and engineering to improve or manipulate brain function. Rapid investments, private-sector involvement, and research innovations, such as brain implants enabling paralysed patients to speak, have increased both possibilities and ethical risks. UNESCO’s new standard attempts to balance innovation and human rights, defining responsibilities for governments, researchers, and companies.

    Why in the News? 

    UNESCO has issued the world’s first global normative framework on the ethics of neurotechnology, marking a major shift in global governance of brain-data systems. This is historic because neurotechnology, once confined to medicine, now expands into marketing, political persuasion, employment screening, insurance, and behaviour profiling. With misuse risks escalating and national laws lagging behind, UNESCO’s framework seeks to protect mental privacy, cognitive liberty, and brain-derived data in an era where neurodata can be exploited commercially or politically.

    How does the article define neurotechnology?

    1. Devices/Procedures: Used to access, assess, and act on neural systems including the brain.
    2. Neurodata: Brain-derived data that can reveal intentions, emotions, or mental states, posing risks of exploitation.
    3. Dual-use potential: While used for medical enhancement or disability support, the same can be misused for persuasion, surveillance, or profiling.

    Why is neurotechnology expanding so rapidly?

    1. Investment surge: According to a UNESCO study (2023), neurotechnology investment reached $8.6 billion, with private investment growing from $7.3 billion by 2020.
    2. Big tech involvement: Projects like US BRAIN Initiative, Elon Musk’s Neuralink accelerating market adoption.
    3. Medical promise: Supports mental health, paralysis recovery, chronic illness treatment, and palliative care.
    4. Commercial incentives: Insurance sector, HR screening, political messaging all exploring neurodata applications.

    What are the key challenges highlighted?

    1. Mental privacy threats: Neurodata gives deep access to personal thoughts; existing legal standards insufficient.
    2. Political misuse: Brain signals used to influence voters or detect political leanings.
    3. Employment misuse: Screening employees for suitability, stress tolerance, or hidden traits.
    4. Commercial exploitation: Recruiting applicants based on subconscious brain responses to marketing stimuli.
    5. Human rights concerns: Risk of discrimination, autonomy loss, and manipulation.

    What does UNESCO’s new framework propose?

    1. Human rights foundation: Anchors mental privacy, liberty, dignity.
    2. Responsible innovation: Based on OECD principles, responsibility, inclusion, sustainability.
    3. Four-pronged strategy:
      1. Scope definition of neurotechnology and neurodata.
      2. Identification of ethical principles for countries.
      3. Recommendations focusing on health, education, and vulnerable groups.
      4. Governance considerations for safety and equity.
    4. Intellectual property balance: Calls attention to potential conflicts between innovation and human rights when brain data becomes privatised.
    5. Open science model: Encourages free sharing of discoveries for societal benefit.
    6. Inclusive innovation: Participation of public, stakeholders, scientists, vulnerable communities.

    What are the implications for governance and public policy?

    1. AI-Neuro convergence: Need for regulations preventing manipulation or exploitation of neural activity.
    2. Global governance: Calls for adoption by states to standardize mental privacy protections.
    3. Sectoral impact: Health, education, military, and employment policies require safeguards.
    4. IP reform: Recommends new licensing structures to prevent monopolisation of brain-interfacing technologies.
    5. R&D ethics: Researchers to involve the public and align innovations with societal needs, not corporate priorities.

    Conclusion

    UNESCO’s guidelines mark a foundational step in governing an emerging field where technological capacity has outpaced ethics. By protecting mental privacy and anchoring innovation within a human-rights framework, the guidelines seek to ensure neurotechnology remains a tool for empowerment rather than manipulation. For India and other countries, the challenge lies in integrating these recommendations into national law and ensuring safe, inclusive, and responsible neuro-innovation.

    PYQ Relevance

    [UPSC 2023] How can Artificial Intelligence (AI) help clinical diagnosis? Do you perceive any threat to privacy of the individual in the use of AI in healthcare?

    Linkage: This directly links to the PYQ on AI in clinical diagnosis because neurotechnology goes even deeper, AI can now read and interpret brain signals, making privacy risks far sharper than ordinary medical data. The same issue fits under Ethics too, since it raises questions about autonomy, consent, dignity, and the basic right to mental privacy.
