Tuberculosis (TB) is a bacterial disease caused by Mycobacterium tuberculosis, identified by Robert Koch on 24 March 1882 — the date now marked as World TB Day. It mainly affects the lungs (pulmonary TB), but can also involve the brain, kidneys and spine (extra-pulmonary TB). Transmission: airborne droplets released when a person with active lung TB coughs, sneezes or speaks; risk is highest in poorly ventilated spaces. It does not spread through handshakes, shared utensils, food or toilets. Latent vs active TB: a person with latent TB infection carries the bacterium without symptoms and is not infectious, but can progress to active disease any time — especially with weak immunity, HIV, diabetes or undernutrition. Infectiousness on treatment: lung-TB patients generally stop being contagious after about two weeks of appropriate treatment; extra-pulmonary TB is usually non-infectious. Drug resistance: MDR-TB (resistant to isoniazid + rifampicin) and RR-TB (rifampicin-resistant) need longer, costlier regimens — the core reason elimination is hard. Vaccine: BCG (Bacille Calmette-Guérin, 1921) protects young children against severe forms but offers limited protection to adults against lung TB. ▤ Programme at a Glance Nodal Ministry: Ministry of Health & Family Welfare; delivered through the National TB Elimination Programme (NTEP) under the National Health Mission. Constitutional anchor: public health is a State subject (Entry 6, List II); Article 47 (DPSP) directs the State to raise nutrition and improve public health. Strategy: National Strategic Plan (NSP) 2017–25, updated as NSP 2020–25, on four pillars — Detect, Treat, Prevent, Build. Flagship add-ons: PM TB Mukt Bharat Abhiyaan (9 Sept 2022), Ni-kshay Mitra, Nikshay Poshan Yojana, 100-Day TB Mukt Bharat Abhiyaan (7 Dec 2024, now nationwide). Benefit structure: ₹1,000 per month via DBT to every notified patient (doubled from ₹500 in 2024); free diagnosis and treatment at public facilities. National target: elimination ahead of the SDG 3.3 deadline of 2030 (India's original stated goal was 2025). Lineage — From Control to Elimination India's TB policy has moved over six decades from controlling the disease to eliminating it — a shift UPSC tests through predecessor–successor pairs. 1962 — National TB Control Programme (NTCP): district TB centres, BCG and domiciliary treatment. 1993 — Revised NTCP (RNTCP): introduced DOTS (Directly Observed Treatment, Short-course), the WHO-recommended strategy. 2012 — TB made a notifiable disease, requiring private providers to report cases. 2018 — Delhi End TB Summit (13 March) and Nikshay Poshan Yojana (April). 2020 — RNTCP renamed NTEP, signalling the move from control to elimination. 2022 — PM TB Mukt Bharat Abhiyaan, adding the Ni-kshay Mitra community-support model; 2023 — TB Mukt Panchayat initiative. Figure 1 — TB control and elimination programmes, 1962–2022 The programme's arc runs from district-level control (1962) to nutrition-linked, community-backed elimination (2018–22).

What the Release Reports — Progress Indicators −21%Incidence, 2015–24 −28%TB deaths, 2015–24 92%Treatment coverage 28.1 crPeople screened Screening and prevention: over 28.1 crore people screened and 20 lakh given TB Preventive Treatment (TPT) under the intensified campaign (as of June 2026). Community layer: 5.7 lakh new Ni-kshay Mitras; 46,118 Gram Panchayats certified TB-free. Second phase (from March 2026): over 1.7 lakh Ayushman Arogya Shivirs across 1.2 lakh high-risk villages and wards. Treatment outcomes: success rate under the Abhiyaan reported at 90%, against a global average of 88%. Nutrition support: ₹4,454.68 crore disbursed to 1.38 crore beneficiaries under Nikshay Poshan since April 2018.

Data as reported in the release, citing WHO's Global TB Report 2025. The Four NSP Pillars and the New Tools The NSP organises every intervention under Detect – Treat – Prevent – Build. The release's new tools map neatly onto these pillars, which is a useful structure for a Mains answer. Detect: over 9,800 rapid molecular testing facilities and 107 culture & drug-susceptibility labs; a 34-fold rise in X-ray screening through 500+ AI-enabled handheld units (another 1,500 being delivered); expanded Truenat (indigenous chip-based PCR) and CBNAAT machines. Treat: the BPaLM regimen — Bedaquiline, Pretomanid, Linezolid, Moxifloxacin — cuts drug-resistant TB treatment to 6 months; 15,000+ MDR/RR-TB patients initiated. Prevent: TPT for household contacts, people living with HIV and other high-risk groups; airborne infection control. Build: Ni-kshay digital platform for DBT; TB Mukt Bharat App with the AI chatbot 'Khushi'; more radiographer posts under NHM; 1,87,250 Ayushman Arogya Mandirs as first contact points. Figure 3 — The four pillars of the National Strategic Plan Build is the broadest pillar — financing, workforce, private-sector engagement, digital systems and rights-based care.

The JOSH Campaign — What is New Format: a nationwide social-media campaign held on 13 October 2026, built around JOSH (Joint Squad for Health) teams, piloted in 55 districts of 11 States. Team composition: MY Bharat volunteers, NCC cadets and a designated Class-I officer in each team. Aim: awareness on early screening, treatment adherence and stigma reduction, and finding asymptomatic cases through active case-finding. MY Bharat (Mera Yuva Bharat, launched 31 Oct 2023) is an autonomous body under the Ministry of Youth Affairs & Sports for youth aged 15–29; over 2 lakh of its volunteers already serve as Ni-kshay Mitras. Why It Matters India carries roughly a quarter of the world's TB burden and a large share of drug-resistant TB. TB is a disease of poverty — linked to undernutrition, crowded housing and delayed care — so progress against it is also a measure of social justice. Economic cost: TB strikes adults in their most productive years, pushing households into catastrophic health spending. Nutrition link: the RATIONS trial (Jharkhand, published 2023) found food support for household contacts cut new TB cases by roughly two-fifths — the evidence base behind Nikshay Poshan and Ni-kshay Mitra food baskets. The Critical View The gains are real, but they should be read against the WHO End TB Strategy (adopted 2014), which set milestones against a 2015 baseline: 50% lower incidence and 75% fewer deaths by 2025; 80% and 90% respectively by 2030. Figure 4 — India's reported progress vs End TB Strategy milestones (reduction from 2015, %) IncidenceDeaths21%50%80%28%75%90%India, 2015–24 (reported)2025 milestone2030 target India's decline beats the global average but sits well short of the End TB 2025 milestones — the honest measure of how far elimination still is. Missed national deadline: India's own target of ending TB by 2025 has passed; the goal is now framed as before 2030. Private-sector gap: a large share of patients first seek care in the private sector, where under-notification and non-standard regimens persist despite mandatory notification (2012). Drug resistance: BPaLM is shorter and safer, but scale-up depends on drug-susceptibility testing capacity and stable supply of bedaquiline and pretomanid. Nutrition adequacy: ₹1,000 a month is modest against food inflation; DBT delays and bank-account barriers have been reported in field studies. Federal capacity: health being a State subject, outcomes vary with State workforce, labs and governance; campaign-mode drives must convert into routine primary-care capacity. Metric caution: campaign figures such as screenings and certified Panchayats are output indicators; elimination is judged on incidence and mortality. ◈ Institutions & Terms to Know Ni-kshay: NTEP's web-based patient management and DBT platform; Ni-kshay Sampark helpline 1800-11-6666. Ni-kshay Mitra: individuals, NGOs, corporates (incl. CSR) adopting patients for nutritional, diagnostic and vocational support. Ayushman Arogya Mandir: the renamed Health & Wellness Centres under Ayushman Bharat (2018) — sub-health centres, PHCs, UPHCs and AYUSH units. TPT: preventive treatment that stops latent infection from becoming active disease. Truenat: indigenous, battery-operated molecular TB test, endorsed by WHO in 2020. ✎ Mains Practice Question India's decline in TB incidence outpaces the global average, yet the End TB milestones remain distant. Critically examine the roles of nutrition support, community mobilisation and new diagnostic and treatment tools in India's TB elimination strategy. 15 marks · 250 words International RelationsGeneral Studies Paper II · with GS-III Security 02 First BIMSTEC Home Ministers’ Meeting Adopts the Delhi Declaration on Regional Security Core TopicGS-II · IR — Regional Groupings; GS-III · Terrorism & Organised CrimePrelims + MainsPIB · Ministry of Home Affairs · 13 Oct 2026 The Home Ministers of the seven BIMSTEC states met for the first time in New Delhi on 13 October 2026 and adopted the Delhi Declaration, adding a ministerial tier to the grouping's security architecture. ◈ Basics First — What is BIMSTEC? The Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) was created by the Bangkok Declaration of 6 June 1997. It links five South Asian and two Southeast Asian states around the Bay of Bengal. Evolution of name: began as BIST-EC (Bangladesh, India, Sri Lanka, Thailand); Myanmar joined in December 1997 (BIMST-EC); Nepal and Bhutan joined in 2004, and it became BIMSTEC. Members (7): Bangladesh, Bhutan, India, Myanmar, Nepal, Sri Lanka, Thailand — home to roughly one-fifth of humanity. Secretariat: Dhaka, set up in 2014. Charter: signed at the 5th Summit, Colombo (March 2022); entered into force in 2024, giving the grouping a formal legal personality. Sectors: rationalised to seven pillars, each led by one member — India leads Security (counter-terrorism, transnational crime, disaster management, energy). Summits: Bangkok 2004 · New Delhi 2008 · Nay Pyi Taw 2014 · Kathmandu 2018 · Colombo 2022 (virtual) · Bangkok April 2025 (adopted Bangkok Vision 2030 and a Maritime Transport Cooperation Agreement). Figure 5 — BIMSTEC member states around the Bay of Bengal Two landlocked Himalayan members (Nepal, Bhutan), one island state (Sri Lanka) and a continuous littoral from India to Thailand — the "common security space" the Declaration refers to.

Outcome document: Delhi Declaration. Mandate origin: 4th Summit, Kathmandu (Aug 2018) decided to hold HMMs; 6th Summit, Bangkok (4 April 2025) welcomed the mechanism to give strategic direction to security cooperation. Guiding principles: sovereign equality, territorial integrity, non-interference, non-aggression, peaceful co-existence; complementary to — not a substitute for — bilateral or other multilateral cooperation. Follow-up body: the Joint Working Group on Counter-Terrorism and Transnational Crime (JWG-CTTC) and its sub-groups. Commitment: members to meet regularly and host future HMMs. Lineage — How BIMSTEC's Security Track Was Built Figure 6 — Building BIMSTEC's security architecture, 1997–2026 1997200920172021202520042014201820222026BangkokDeclarationCT Conventionsigned1st NSAs’ meetNew DelhiCT Conventionin forceBangkok SummitHMM welcomedJWG-CTTCset upSecretariatin DhakaKathmandumandates HMMCharter + MLAConvention1st HMMDelhi Decl. Security cooperation moved from a working group (2004) to treaties (2009, 2022), an NSA track (2017) and now a ministerial tier (2026). Key Provisions of the Delhi Declaration The Declaration treats the Bay of Bengal as a common security space facing threats that are transnational by nature. Its provisions fall into four clusters. Terrorism: condemns terrorism "in all its forms and manifestations", explicitly including cross-border terrorism; calls for implementing UN Security Council sanctions, including the 1267 Sanctions Committee regime; stresses countering radicalisation, terror financing, recruitment and misuse of emerging technologies. Legal architecture: full implementation of the BIMSTEC Convention on Combating International Terrorism, Transnational Organised Crime and Illicit Drug Trafficking (in force March 2021) and the Convention on Mutual Legal Assistance in Criminal Matters (signed March 2022); early finalisation of conventions on Extradition, Transfer of Sentenced Persons and Trafficking in Persons. Scam centres and trafficking: recognises that crime groups traffic people and force them into online fraud — "forced criminality" and debt bondage; seeks cooperation among origin, transit and destination states through a victim-centred approach, plus an SoP for Rescue, Repatriation and Reintegration. Mechanisms and partners: a BIMSTEC Drug Offences Monitoring Desk (BDOMD); a proposed regional information-sharing mechanism on trafficking and migrant smuggling; training at members' premier institutions; partnerships with UNODC, INTERPOL, FATF; welcomes the Secretariat's Observer status at the Asia/Pacific Group on Money Laundering (APG). Why It Matters for India Regional platform: with SAARC dormant since the 2016 Islamabad Summit was called off (the last summit was in 2014), BIMSTEC has become India's main sub-regional forum — at the meeting point of Neighbourhood First, Act East and MAHASAGAR. North-East security: the region borders the Golden Triangle; UNODC (2023) found Myanmar had overtaken Afghanistan as the world's largest opium producer, with spill-over into Manipur and Mizoram. Citizens at risk: Indian nationals have been trafficked into cyber-scam compounds in Myanmar and other Southeast Asian states; over 500 were repatriated from Myawaddy via Thailand in 2025. Narrative on terrorism: regional endorsement of the cross-border terrorism formulation and the 1267 regime supports India's long-standing push, including for a Comprehensive Convention on International Terrorism (CCIT), proposed by India at the UN in 1996. The Critical View Implementation lag: the counter-terrorism convention took about 12 years to enter into force (signed 2009, effective 2021); extradition and trafficking conventions are still being drafted. Myanmar's situation: internal conflict since the 2021 military takeover limits the state's ability to act on scam compounds, drugs and border control — the very issues the Declaration targets. Political volatility: changes of government in Bangladesh and Sri Lanka and India–Bangladesh frictions can slow consensus-based cooperation. Sensitivities: smaller members are wary of anything seen as India-centric; the Declaration's emphasis on non-interference and national legal frameworks reflects this. Weak economic base: intra-BIMSTEC trade remains a small share of members' total trade, and the BIMSTEC FTA (framework agreed in 2004) is still not concluded — security cooperation is running ahead of economic integration. Federal angle: police is a State subject (Entry 2, List II) while extradition is a Union subject (Entry 18, List I), so Union–State coordination is needed to deliver on commitments. ◈ Institutions & Terms to Know 1267 Committee: UNSC sanctions committee created by Resolution 1267 (1999); now covers ISIL (Da'esh) and Al-Qaida-linked individuals and entities. FATF: set up in 1989 by the G7 in Paris; India has been a full member since 2010. APG: the FATF-style regional body for the Asia-Pacific, established in 1997, secretariat in Sydney. JWG-CTTC: BIMSTEC's working group on counter-terrorism and transnational crime, with sub-groups including the SG-CCRT (countering radicalisation and terrorism). Track 1.5 dialogue: a mix of official and non-official (think-tank, academic) participants. ✎ Mains Practice Question With SAARC largely inactive, BIMSTEC is emerging as India's preferred platform for regional security cooperation. Discuss the opportunities and limitations of this shift in the light of the Delhi Declaration adopted at the first BIMSTEC Home Ministers’ Meeting. 15 marks · 250 words Internal Security & DefenceGeneral Studies Paper III 03 Navy to Commission ‘Samarthak’, First of Four Indigenous Multi-Purpose Vessels, at Karwar ImportantGS-III · Security — Defence Indigenisation, Maritime SecurityPrelims + MainsPIB · Ministry of Defence · 13 Oct 2026 The Indian Navy will commission Samarthak, the first of four Multi-Purpose Vessels (MPVs) built by Larsen & Toubro (L&T), at Naval Base Karwar on 16 October 2026 — a private-yard, utility warship designed to free frontline combatants from secondary tasks. Figure 7 — Multi-Purpose Vessel Samarthak at sea A mid-sized utility hull with a large open aft deck — suited to launching targets, unmanned systems and relief stores. Image courtesy PIB / Ministry of Defence; reproduced with credit for educational use. ◈ Basics First — Why Navies Need ‘Utility’ Ships A navy's destroyers and frigates are expensive, high-end combatants. Using them for routine patrol, weapons-trial support or disaster relief wears out costly hulls. Utility vessels take over these secondary roles, so combatants stay available for high-intensity missions. Low Intensity Maritime Operations (LIMO): tasks below the threshold of war — anti-piracy, anti-smuggling, EEZ patrol, fisheries protection, and countering illegal migration. HADR: Humanitarian Assistance and Disaster Relief — a core part of the Navy's role as "first responder" in the Indian Ocean Region (e.g., Operation Brahma, Myanmar earthquake, 2025). Mothership: a vessel that launches, controls and recovers unmanned aerial, surface or underwater systems. ▤ Vessel at a Glance Name: Samarthak — first of a four-ship MPV series. Builder: Larsen & Toubro Ltd — a private-sector shipyard — under Make in India (launched September 2014). Commissioning: 16 October 2026, Naval Base Karwar (Karnataka). Nodal Ministry: Ministry of Defence; Defence is a Union subject (Entry 1, List I). Primary role: maritime surveillance and patrol. Combat suite: indigenous sensors, weapons and electronic systems, as stated by the Navy. Crest & motto: an Indian elephant rising from the waves (strength, intelligence, agility); Sanskrit motto “विजयार्थम् एकनिष्ठता” — single-minded commitment to victory. Roles the Vessel is Designed For Figure 8 — One hull, seven roles: the MPV concept MPVSamarthakSurveillance & PatrolLow-Intensity Maritime OpsTarget Deployment & TrialsUnmanned Systems MothershipHADR MissionsLimited Hospital ShipSalvage OperationsSecurity & trials rolesHumanitarian & support roles Security and trials roles (left) and humanitarian and support roles (right), as listed in the release — the logic of a "utility" ship. Static Anchor — Karwar and Project Seabird INS Kadamba, the naval base at Karwar in Uttara Kannada district, Karnataka, was commissioned in 2005 under Project Seabird. Located on the Arabian Sea coast, Karwar gives the Western Naval Command a deep-water base away from the congested Mumbai harbour; Phase II expansion is under way. The aircraft carrier INS Vikramaditya is based at Karwar. Why It Matters — Indigenisation and the Private Yard Private-sector shipbuilding: warship building has traditionally been dominated by defence PSU yards (Mazagon Dock, GRSE, Goa Shipyard, Cochin Shipyard); an L&T-built series widens India's industrial base. Policy framework: Defence Acquisition Procedure (DAP) 2020 prioritises the Buy (Indian-IDDM) category; the Department of Military Affairs has notified five Positive Indigenisation Lists covering 509 items that cannot be imported. Output trend: India's defence production reached about ₹1.51 lakh crore and defence exports about ₹23,622 crore in 2024–25, both record highs. Strategic fit: extra patrol and HADR hulls support India's aim to be a "preferred security partner" and first responder under MAHASAGAR (successor to SAGAR, 2015). The Critical View Jack of all trades: multi-role designs trade depth for flexibility; the MPV is not a frontline combatant and needs escort in contested waters. Import content: "indigenous" platforms can still depend on imported engines, propulsion and sub-systems; the share of indigenous content matters more than the label. Delivery timelines: Indian shipbuilding has a history of cost and time overruns; timely delivery of the remaining three vessels will test the model. Capacity gap: India's share of global shipbuilding is under 1%; the ₹69,725 crore shipbuilding and maritime package approved in September 2025 aims to address this. ✎ Mains Practice Question Utility platforms such as Multi-Purpose Vessels act as force multipliers for a navy that seeks to be the first responder in the Indian Ocean Region. Discuss in the context of India's push for indigenous, private-sector warship building. 10 marks · 150 words

Editorials, Opinions & Explained2 Items Core TopicImportantConcise OpinionsGS II · GS III · GS IV 01Overtreatment & Overmedication in Indian Health Care02CSR at ₹40,000 Crore — From Spending to Impact OpinionsSigned op-eds · GS Papers II, III & IV 01 When Medicine Does Too Much: Overtreatment, Overmedication and the Case for Clinical Restraint Core TopicOpinionGS-II · Health — Health Systems, Regulation of Medical PracticePrelims + MainsThe Hindu · Op-Ed · Chandrakant Lahariya The author argues that India's health system exhibits a dual pathology — overtreatment of those who can pay coexisting with undertreatment of those who cannot — and that the next phase of medical progress lies as much in knowing when not to intervene as in expanding what can be done. ◈ Conceptual Foundations The critique of excess medicine has a long intellectual lineage. Ivan Illich's Medical Nemesis (1975) introduced the idea of iatrogenesis — harm caused by medical care itself — and warned against the medicalisation of ordinary life. Overdiagnosis: detection of a condition that would never have caused symptoms or death; it converts healthy people into patients without improving outcomes. Overtreatment: interventions whose likely harms or costs exceed their benefits for a given patient. Polypharmacy: concurrent use of, conventionally, five or more medicines; risk rises with age because of altered drug metabolism and multiple chronic conditions. Deprescribing: the planned, supervised reduction or withdrawal of medicines whose risks now outweigh benefits. Tools include the Beers Criteria (American Geriatrics Society) and STOPP/START criteria. Information asymmetry: Kenneth Arrow (1963) showed that patients cannot judge the necessity of care, giving providers scope for supplier-induced demand. The Cascade of Care The article's central insight is that overtreatment is rarely a single wrong decision. It is typically a sequence, each step individually defensible, that ends in permanent medication or a procedure the patient may never have needed. Figure 1 — How a routine test can escalate into lifelong treatment Without a gatekeeper or a review date, the chain rarely reversesRoutine testor check-upIncidentalabnormalityFurther testsand scansNew diagnosis(a ‘label’)Prescriptionor procedureLifelongmedicationEach step adds cost, anxiety and a fresh risk of iatrogenic harm The remedy is not fewer tests as such, but decision points — a family physician, a review date, a structured medication review — at which the cascade can be stopped. Five Drivers Identified by the Author Indiscriminate testing: bundled health-check packages generate false positives and incidental findings; the capacity to test has outpaced clinical judgment on whom to test. Fragmented care: patients bypass generalists for specialists and super-specialists, each optimising one organ system; nobody reconciles the whole prescription. Marketisation: tests, procedures, supplements and devices are sold as products; the fee-for-service model rewards volume over restraint, and patients often equate a "complete" consultation with a long prescription. Patient expectations: under uncertainty, reassurance and watchful waiting appear as inaction, while a scan or pill appears decisive — and crowded clinics leave little time to explain. Defensive medicine: fear of a missed diagnosis — and of litigation — makes one more test look like the safer choice, though every test carries its own downstream risk. The Evidence Cited ~49%Older adults with polypharmacy (meta-analysis, 2021) ~1 in 3Older adults on 5+ medicines (study, 2025) 28.8%Cases with potentially inappropriate medicines The author is careful to note that multiple medicines are not proof of overtreatment; the figures instead establish why periodic medication review must become routine, particularly as India ages. The India Ageing Report 2023 (UNFPA) projects the elderly share of the population to exceed 20% by 2050. Corroborating Evidence — The Caesarean Example Caesarean delivery is a widely studied marker of provider-driven intervention. NFHS-5 (2019–21) data show a pronounced gap between public and private facilities, well above the level that WHO (2015) found to be associated with lower maternal and newborn mortality at population level (around 10%). Figure 2 — Births by caesarean section, India, NFHS-5 (2019–21), % Public facilitiesAll birthsPrivate facilities14.3%21.5%47.4%WHO reference ≈ 10%01020304050 Nearly one in two births in private facilities is by caesarean section — more than three times the public-facility rate — consistent with the incentive effects the author describes. Source: NFHS-5; WHO Statement on Caesarean Section Rates (2015). The Policy and Legal Landscape Constitutional frame: public health is a State subject (Entry 6, List II); Article 47 places a duty on the State to improve public health; the Supreme Court has read a right to health into Article 21 (Paschim Banga Khet Mazdoor Samity, 1996). Primary care as gatekeeper: the Alma-Ata Declaration (1978) and Astana Declaration (2018) place primary care at the centre of health systems; the National Health Policy 2017 sought to allocate two-thirds or more of public health resources to primary care. Ayushman Bharat (2018): Ayushman Arogya Mandirs provide the first-contact layer; AB-PMJAY provides hospitalisation cover of ₹5 lakh per family per year, extended in 2024 to all citizens aged 70 and above. Standard treatment guidelines: the Clinical Establishments (Registration and Regulation) Act, 2010 empowers prescription of standard treatment guidelines, but adoption across States remains partial. Medical liability: Indian Medical Association v. V.P. Shantha (1995) brought medical services under consumer protection law; Jacob Mathew v. State of Punjab (2005) set a high threshold of "gross negligence" for criminal liability — both shape the incentives behind defensive medicine. Antimicrobial misuse: the National Action Plan on AMR (2017) recognises irrational antibiotic prescription as a form of overmedication with population-level consequences. The Insurance Paradox — Moral Hazard Insurance protects households from catastrophic expenditure, yet it can alter behaviour. Ex-ante moral hazard weakens incentives for prevention, since illness is financially cushioned; ex-post moral hazard raises utilisation once illness occurs, because the insurer, not the patient, bears the marginal cost. Under package-based reimbursement, providers may favour procedures that are well remunerated over conservative management. The author's ethical point is sharp: a third party bears the cost, but the patient's body bears the risk; paying premiums creates no reason to "recover" value through surgery. Remedies Proposed — and an Assessment Restore the family physician as the first point of contact, with specialist referral through a defined pathway — the gatekeeper model of the UK's NHS and several European systems. Review and stop dates on prescriptions, and structured medication reviews for older adults and anyone on five or more medicines. Indian low-value care lists developed by professional societies and the ICMR, modelled on the Choosing Wisely campaign (begun in the US in 2012; about 80 societies issued nearly 700 recommendations by 2023), embedded in training and accreditation (e.g., NABH). Four patient questions — Why do I need this? What if I wait? What are the benefits and risks? What are the alternatives? — to support shared decision-making. Payment reform towards outcomes, continuity and clinical reasoning, for instance capitation or bundled payments, rather than volume. The proposals are well grounded, but three constraints deserve attention. India's primary-care workforce is thin, especially in cities where specialists dominate. Most care is delivered in a loosely regulated private sector. And any campaign against "low-value care" must avoid deepening undertreatment among the poor, for whom the problem is too little care, not too much. ✎ Mains Practice Question “In India, overtreatment coexists with undertreatment.” Examine the structural drivers of overmedicalisation in the Indian health system and suggest measures to align clinical incentives with patient welfare. 15 marks · 250 words 02 A Decade of Mandatory CSR: Moving the Measure from Rupees Spent to Outcomes Achieved Core TopicOpinionGS-III · Economy — Mobilisation of Resources, Inclusive Growth; GS-IV · Corporate GovernancePrelims + MainsThe Indian Express · Op-Ed · Purvi Mehta India's mandatory Corporate Social Responsibility (CSR) regime has mobilised about ₹2.6 lakh crore in a decade and ₹40,794 crore in 2024–25 alone; the author contends that the policy question must now shift from how much is spent to what that spending achieves. ◈ Static Anchor — The Legal Framework India became the first country to make CSR spending a statutory obligation, through Section 135 of the Companies Act, 2013, effective 1 April 2014. Eligible activities are listed in Schedule VII of the Act. Applicability: a company with net worth ≥ ₹500 crore, turnover ≥ ₹1,000 crore or net profit ≥ ₹5 crore in the preceding financial year. Obligation: spend at least 2% of average net profits of the three immediately preceding financial years. Governance: a board-level CSR Committee is required where the obligation exceeds ₹50 lakh; implementing agencies must register with the MCA (Form CSR-1). Unspent funds (2019 and 2021 amendments): amounts for ongoing projects go to an Unspent CSR Account and must be used within three years; other unspent sums go to a Schedule VII fund within six months. Enforcement: non-compliance was decriminalised in 2020 and now attracts monetary penalties. Impact assessment: under the CSR Rules, 2021, companies with average obligations of ₹10 crore or more must commission independent impact assessments for projects of ₹1 crore or more. Tax treatment: CSR expenditure is not deductible as a business expense under income-tax law, reflecting its character as an obligation, not a cost of earning income. ▤ The Numbers (as reported for 2024–25) Total CSR spend: ₹40,794 crore by about 29,500 companies across roughly 72,000 projects. Cumulative mobilisation since 2014: about ₹2.6 lakh crore. Top four destinations: Maharashtra ₹8,631 crore, Gujarat ₹4,549 crore, Karnataka ₹3,395 crore, Delhi ₹2,753 crore — together about ₹19,300 crore, or roughly 47% of the total. Average project size: about ₹57 lakh (₹40,794 crore ÷ 72,000) — an indicator of fragmentation. Figure 3 — Where CSR money went, 2024–25 (₹ crore) MaharashtraGujaratKarnatakaDelhiAll others*8,6314,5493,3952,75321,466*All other States/UTs and multi-State (‘PAN India’) projects; total minus the four named. Four relatively developed States and UTs absorb close to half of all CSR spending, while the remaining 30-odd States and UTs and multi-State projects share the rest. The Author's Diagnosis The argument is not that CSR money is wasted — much of it supports education, health and livelihoods — but that the sum of tens of thousands of discrete projects is unknown. Two structural weaknesses follow. Geographic skew: spending follows corporate location (registered offices and plants) rather than development deficit. Section 135 itself asks companies to give preference to the local area of operations, which partly institutionalises this skew. Fragmentation: many small, short-cycle projects produce outputs — beneficiaries counted, assets built — without systemic change in a district's health or learning outcomes. From Inputs to Impact — The Results Chain Figure 4 — Where CSR accountability sits today, and where it needs to move Current reporting focusWhere accountability should moveInputsActivitiesOutputsOutcomesImpact₹ spentprojects runpeople reachedlearning, healthdistrict systemsMeasured by the 2% compliance testNeeds common indicators, pooled fundsand longer project horizons The 2% rule audits the first link of the chain; the reforms proposed aim to make the last two links the test of success. Three Reforms Proposed Outcome accountability: pair the existing spend-based compliance with standardised outcome indicators, so results are comparable across companies and sectors. Aggregation: use the law's existing provision for collaboration to pool funds around common themes and geographies — ten firms jointly committing ₹100 crore to one results framework can shift a district system in a way ten scattered ₹10-crore projects cannot. Core competence: deploy knowledge, networks and managerial capacity, not only money — an agri-business supporting farmer productivity and value chains is likely to achieve more than it would in an unrelated sector. Analytical Perspectives Theoretical frame: the third reform echoes Porter and Kramer's "Creating Shared Value" (2011), which argues that firms create most social value where it intersects with their business, in contrast to Milton Friedman's (1970) view that business's sole social responsibility is profit within the rules. Indian roots: Gandhi's idea of trusteeship — wealth held in trust for society — is often cited as the ethical antecedent of Indian corporate philanthropy. Aligning with public priorities: the Aspirational Districts Programme (2018, 112 districts) and Aspirational Blocks Programme (2023, 500 blocks) offer ready geographies and indicator frameworks for directing pooled CSR. Outcome-based instruments: SEBI's Social Stock Exchange framework (2022) and development impact bonds such as the Utkrisht DIB (maternal health, Rajasthan) pay against verified results — models CSR could adopt. The Critical View A quasi-tax? Critics argue that a mandated, non-deductible spend functions as an earmarked levy on profits, while leaving allocation to firms that may lack development expertise. Directing spending has limits: steering CSR towards specific districts could dilute corporate discretion, the very feature that distinguishes CSR from taxation. Measurement cost: rigorous impact evaluation is expensive; demanding it of small projects may consume a large share of their budgets — hence the current ₹10-crore / ₹1-crore thresholds. Supplement, not substitute: at about ₹41,000 crore a year, CSR is significant but small beside public spending on the social sector; the author rightly frames it as a supplement to public expenditure. ✎ Mains Practice Question A decade after India made Corporate Social Responsibility mandatory, the debate has shifted from how much is spent to what is achieved. Critically evaluate the CSR framework under the Companies Act, 2013, and suggest reforms to improve its developmental impact. 15 marks · 250 words

Authorities had restricted entry and exit at 57 Metro stations and 254 trains were cancelled. 9 October: the Supreme Court questioned blanket transport shutdowns — cautioning against using "a hammer to kill a fly" — and recorded a suggestion that suitable alternative sites with basic amenities be identified and designated. 11 October: in a rare Sunday hearing, the Court directed that Metro, rail and internet services operate normally, barricades be reviewed, there be no unlawful detention, and peaceful assemblies be allowed except in areas under Section 163 BNSS orders. 12 October: Jantar Mantar denotified; the police cited the SC's 9 October observation and recommendations of a Ministry of Home Affairs committee. 13 October: before the Delhi High Court, the Centre argued that a pending petition seeking permission to protest at Jantar Mantar had become infructuous; the Court issued notice on the petitioner's wider challenge — to "automatic, mechanical" refusals and the 10-day advance-application rule — returnable on 17 November. The denotification itself has been challenged before the SC. Static Anchor — The Constitutional Framework Article 19(1)(a) — freedom of speech and expression; Article 19(1)(b) — right to assemble peaceably and without arms; Article 19(1)(d) — free movement throughout India. Article 19(2) and 19(3) allow reasonable restrictions — on assembly, only in the interests of sovereignty and integrity of India and public order. Kameshwar Prasad v. State of Bihar (1962): peaceful demonstrations are a form of expression protected by Articles 19(1)(a) and (b). Proportionality test (Modern Dental College, 2016; K.S. Puttaswamy, 2017): a restriction must pursue a legitimate aim, be rationally connected to it, be the least restrictive means, and balance rights against the aim. Delhi's peculiarity: under Article 239AA(3)(a), public order and police are outside the Delhi Legislative Assembly's domain; the Delhi Police reports to the Union Ministry of Home Affairs. International law: Article 20, UDHR and Article 21, ICCPR recognise peaceful assembly; the UN Human Rights Committee's General Comment No. 37 (2020) holds that assemblies should be allowed within "sight and sound" of their target audience. How the Courts Have Drawn the Line Figure 1 — Protest sites and the courts in Delhi: a timeline 1973201220182026199320172020Himat Lal Shahregulate, not banRamlila Maidanmidnight order faultedMKSS judgmentblanket ban set asideBoat Club lawnsclosed to protestsNGT halts protestsat Jantar MantarShaheen Baghno indefinite blockadeJantar Mantardenotified The consistent judicial thread: the State may regulate time, place and manner of protest, but may not convert regulation into prohibition. Himat Lal K. Shah v. Commissioner of Police (1973): streets serve many purposes, so assemblies may be regulated; but rules cannot confer an arbitrary power to refuse permission. In Re: Ramlila Maidan Incident (2012): the Court faulted the use of prohibitory orders against a sleeping crowd at night — such power is for sudden and grave emergencies. Mazdoor Kisan Shakti Sangathan v. Union of India (2018): set aside the NGT's 2017 blanket ban on protests at Jantar Mantar and Boat Club; directed a regulatory mechanism balancing protesters' rights against those of residents and commuters. Amit Sahni v. Commissioner of Police (2020, Shaheen Bagh): dissent is protected, but public roads cannot be occupied indefinitely; protests must be at designated places. Anuradha Bhasin v. Union of India (2020): prohibitory orders may anticipate danger, but must be proportionate and cannot be used to suppress legitimate expression. The Two Sides of the Debate The policing view: designated sites have finite capacity; central Delhi concentrates Parliament, Rashtrapati Bhavan and the Supreme Court in a small area; and Section 168 BNSS gives police a statutory duty to prevent cognisable offences, so they need not wait for violence. The rights view: protest is communication, not mere assembly; moving it to distant grounds such as Burari can make it inaudible. Blanket Metro and rail closures burden thousands of unrelated commuters and fail the least-restrictive-means test when targeted measures exist. Targeted alternatives raised by former police officers: crowd caps, selective station control and interception of identified groups, rather than city-wide disruption. Past violence may inform risk assessment, but it does not create an unlimited power to prohibit every later gathering — courts demand a rational nexus between the apprehended danger and the restriction. Process concerns: the denotification was notified hours after the Centre sought an adjournment in a pending case — raising questions of transparency that the courts will now examine. ▤ Key Facts New designated sites: Ramlila Ground, Burari Ground, CBD Ground. Restrictions sought: closure of gates at 57 Metro stations; 254 trains to or from Delhi cancelled. Detentions: over 5,000 people were reported detained while trying to reach Jantar Mantar. Oversight: an SC-constituted High-Powered Enquiry Committee (August 2026) is examining the July violence, alleged excesses, and the use of blanket Section 163 orders. ✎ Mains Practice Question The right to protest is integral to a constitutional democracy, yet its place and manner remain subject to regulation. Examine this balance in the light of judicial pronouncements on designated protest sites in India. 15 marks · 250 words 02 Preventive Detention and Prohibitory Orders: What the Law Permits and Where the Constitution Draws the Line Core TopicGS-II · Polity — Arts. 21 & 22, Criminal Procedure; GS-III · Internal SecurityPrelims + MainsThe Hindu · The Indian Express Mass detentions during the Delhi protests and the SC's insistence that "all detentions must follow procedure established by law" make it essential to distinguish three distinct powers: preventive detention, prohibitory orders, and police preventive action. ◈ Basics First — Three Different Powers Preventive detention: detention without trial or conviction, to stop a person from future acts prejudicial to the State, public order or essential supplies — not to punish a past offence. Governed by Article 22(3)–(7) and laws such as the National Security Act, 1980. Prohibitory order — Section 163, BNSS (formerly Section 144, CrPC): an Executive Magistrate may restrain acts or gatherings to prevent obstruction, danger to life or a breach of public tranquillity; valid for up to two months, extendable by the State to six months. Police preventive action — Sections 168 and 170, BNSS (formerly 149 and 151, CrPC): police must prevent cognisable offences and may arrest to do so; such detention ordinarily cannot exceed 24 hours without a magistrate's order. Law and Order, Public Order, Security of State In Ram Manohar Lohia v. State of Bihar (1966), the SC explained these as three concentric circles. A disturbance that touches only individuals is a law-and-order matter; preventive detention for "public order" needs a disturbance to the life of the community. Figure 2 — The ‘concentric circles’ test (Ram Manohar Lohia, 1966) Law and OrderPublic OrderSecurityof StateLaw and order — widest circleIndividual disturbances; handled byordinary criminal law and police actionPublic order — the middle circleAffects the community at large;ground for detention and Sec. 163 ordersSecurity of State — innermostRebellion, war, terrorism;NSA, UAPA-type special lawsEvery security threat affects public order,but not every law-and-order problem does. The wider the circle invoked, the weaker the justification for extraordinary powers — the test courts apply when reviewing detention orders. Constitutional Safeguards — Article 22 Article 22(1)–(2) — ordinary arrest: right to be told the grounds of arrest, to consult a lawyer, and to be produced before a magistrate within 24 hours. Article 22(3): these protections do not apply to enemy aliens or persons held under preventive detention laws. Article 22(4): no detention beyond three months unless an Advisory Board (persons qualified as High Court judges) reports sufficient cause. The 44th Amendment (1978) reduced this to two months, but that clause has never been notified. Article 22(5): grounds must be communicated as soon as may be, with the earliest opportunity to make a representation; Article 22(6) lets facts be withheld in the public interest. Legislative competence: Parliament — Entry 9, List I (defence, foreign affairs, security of India); Parliament and States — Entry 3, List III (security of a State, public order, essential supplies). ▤ National Security Act, 1980 — Key Provisions Grounds: acts prejudicial to defence of India, foreign relations, security of India or a State, public order, or maintenance of essential supplies. Advisory Board: reference within 3 weeks of detention; report within 7 weeks. Maximum detention: 12 months from the date of detention. Evolution — From Colonial Tool to Constitutional Exception Colonial era: Bengal Regulation III of 1818, the Rowlatt Act (1919) and the Defence of India Act (1939) allowed detention without trial, chiefly against the national movement. Post-1950: Preventive Detention Act, 1950 (lapsed 1969) — upheld in A.K. Gopalan (1950); MISA, 1971, used extensively during the Emergency (1975–77) and repealed in 1978; COFEPOSA, 1974; NSA, 1980. Doctrinal shift: Maneka Gandhi (1978) required any procedure curtailing liberty to be "just, fair and reasonable", linking Articles 14, 19 and 21 — the "golden triangle". India is among the few democracies that provide for preventive detention in peacetime within the Constitution itself. Judicial Guard-Rails Babulal Parate (1961) and Madhu Limaye (1970): upheld Section 144 but limited it to urgent, specific threats — the power is not "unlimited or untrammelled". Khudiram Das v. State of West Bengal (1975): communicating grounds is a check on arbitrary detention and enables judicial review. Shaik Nazneen v. State of Telangana (2022): preventive detention is an exceptional power, not a substitute for ordinary criminal law. Ameena Begum v. State of Telangana (2023): safeguards under the golden triangle must be diligently enforced. Remedy: habeas corpus under Article 32 (SC) and Article 226 (High Courts) — invoked in the current case to seek explanations for alleged mass detentions. Critical Appraisal The constitutional design accepts preventive detention as a necessary exception, but its legitimacy depends on strict compliance. Recurring concerns include routine use against protesters, unclear distinctions between law and order and public order, and Advisory Boards that rarely overturn orders. ✎ Mains Practice Question Preventive detention has been described as a ‘necessary evil’ in India's constitutional scheme. Critically examine the safeguards under Article 22 and the judicial approach to preventive detention and prohibitory orders. 15 marks · 250 words 03 Legal Aid Cuts Jail Time for Undertrials — But Help Often Arrives Too Late Core TopicGS-II · Polity — Judiciary, Access to Justice, Vulnerable SectionsPrelims + MainsThe Hindu · Data Point An analysis of over 22,000 undertrials assisted by a legal-aid programme in eight Maharashtra prisons (2018–23) shows that legal help sharply raises bail success — but that participants had already spent an average of 171 days in jail before help arrived. ◈ Basics First — The Undertrial Problem An undertrial is a person held in custody while their case is pending, presumed innocent until convicted. India's incarceration rate is low — about 41 per 1,00,000 people — yet over three-quarters of prisoners in 2022 were undertrials, placing India fourth in the world by this share. Prisons are a State subject (Entry 4, List II); the Centre guides through the Model Prison Manual, 2016 and the Model Prisons and Correctional Services Act, 2023. Prison Statistics India 2022 (NCRB): undertrials formed about 75.8% of inmates and occupancy was about 131%. Bail jurisprudence: "bail is the rule, jail the exception" (State of Rajasthan v. Balchand, 1977); Satender Kumar Antil v. CBI (2022) issued detailed bail guidelines. Static Anchor — The Right to Free Legal Aid Article 39A (inserted by the 42nd Amendment, 1976): the State shall provide free legal aid so that justice is not denied for economic or other disabilities. M.H. Hoskot v. State of Maharashtra (1978) and Hussainara Khatoon v. State of Bihar (1979): free legal aid and speedy trial are part of Article 21; Khatri v. State of Bihar (1981): the right begins at the first production before a magistrate. Legal Services Authorities Act, 1987 (in force 9 November 1995 — National Legal Services Day): created NALSA, with the Chief Justice of India as Patron-in-Chief, and State, District and Taluk authorities. Section 12 eligibility includes SC/ST members, women and children, persons in custody, persons with disabilities, trafficking victims and those below an income limit. Legal Aid Defence Counsel System (2022): a public-defender-style model of full-time legal aid lawyers in criminal cases. Section 479, BNSS (formerly 436A CrPC): release on bond after serving half the maximum sentence — one-third for first-time offenders. ▤ The Programme and Its Participants Implementers: Prayas (TISS) and the Fair Trial Fellowship (NLU Delhi); running since 2018 in eight prisons. Profile: typical participant aged 29; nearly half educated only to primary level; 18% women; 57% casual wage workers. Backlog: in 2018, about 37% of Maharashtra's 26,898 undertrials had been held for more than a year. Income loss: up to about ₹2 lakh for some age groups, while over 60% earn under ₹80,000 a year; post-intake losses average ₹80,000 for the most serious charges vs ₹21,000 for the least serious.

Participants did better than the district average in 28 of 29 districts, and the gap persists within offence-severity categories. Comparisons are descriptive, not causal. Figure 4 — Average time in custody, arrest to release on bail (days) ArrestLegal-aid intakeBail release171 days before any legal aid115 days more≈ 286 days — about eight months — from arrest to release Three-fifths of the time in custody passes before legal aid reaches the undertrial — the central policy lesson of the study. Why It Matters Procedural, not legal, barriers: the programme's gains came from filing bail applications, coordinating with advocates, gathering documents and meeting bail conditions — frictions that keep the poor in jail. Economic case: shorter detention eases overcrowding, reduces public spending on prisons and limits income loss for households that live on daily wages. Surety barrier: many undertrials secure bail but cannot furnish sureties; the Support to Poor Prisoners scheme (2023) addresses this financially. The Way Forward Early identification: reach eligible persons at or soon after arrest, as Khatri envisaged, rather than months later. Better data: caste, religion, income and migration status are missing for much of the sample; tracking people after release would show whether gains last. Rigorous evaluation: comparing participants with similar defendants in court records would establish causal impact. Quality of aid: strengthen remuneration, training and monitoring of panel lawyers, a long-standing weakness of the legal-services system. ✎ Mains Practice Question Despite Article 39A and the Legal Services Authorities Act, 1987, undertrials make up over three-fourths of India's prison population. Discuss the causes and suggest how legal aid can be made timely and effective. 15 marks · 250 words Science & TechnologyGeneral Studies Paper III · with GS-II Health 04 ICMR Lays Foundation of High-Altitude Health Research Centre at Keylong, Lahaul-Spiti ConciseGS-III · S&T — Health Research; GS-II · HealthPrelims + MainsPIB · Ministry of Health & Family Welfare The foundation stone of what the Government describes as the country's first High-Altitude Health Research Centre of the ICMR was laid at Keylong, headquarters of Lahaul and Spiti district, Himachal Pradesh — a joint initiative with the Armed Forces Medical Services (AFMS). ◈ Basics First — Why Altitude Affects Health With altitude, atmospheric pressure falls, and so does the partial pressure of oxygen. At about 3,000 m, each breath carries roughly 30% less oxygen than at sea level, causing hypobaric hypoxia. Acute Mountain Sickness (AMS): headache, nausea, fatigue — common above about 2,500 m. HAPE (High-Altitude Pulmonary Oedema) and HACE (High-Altitude Cerebral Oedema): life-threatening fluid build-up in the lungs or brain. Other risks: frostbite, hypothermia, intense UV exposure, and chronic mountain sickness among long-term residents. Acclimatisation: staged ascent lets the body raise breathing rate and red-cell production — the basis of the Army's acclimatisation protocols. Key Points Location: Keylong (about 3,000 m), in the largely tribal Lahaul and Spiti district — a Fifth Schedule Scheduled Area, now connected year-round by the Atal Tunnel (9.02 km, opened 2020). Mandate: study the health effects of extreme high-altitude conditions on local tribal communities and armed forces personnel deployed in the Himalaya. ICMR: founded in 1911 as the Indian Research Fund Association, renamed in 1949; India's apex biomedical research body under the Department of Health Research. Existing work: DRDO's Defence Institute of Physiology and Allied Sciences (DIPAS) has long researched high-altitude physiology for soldiers; the new centre adds a civilian and community-health focus. ✎ Mains Practice Question Discuss the health challenges faced by populations and personnel in India's high-altitude regions. How can dedicated research institutions contribute to both public health and national security? 10 marks · 150 words Environment & EcologyGeneral Studies Paper III 05 India's Water Treatment Plants Are Not Catching ‘Forever Chemicals’ — and There Is No Drinking-Water Limit Yet Core TopicGS-III · Environment — Pollution, Emerging Contaminants; S&TPrelims + MainsThe Hindu · Science Studies from Chennai, Visakhapatnam and several States have detected per- and polyfluoroalkyl substances (PFAS) in Indian water, yet conventional treatment does not remove them, the national extent of contamination is unknown, and IS 10500:2012 sets no PFAS limit. ◈ Basics First — What Are PFAS? PFAS are a large family of synthetic compounds with chains of carbon–fluorine (C–F) bonds, among the strongest bonds in organic chemistry. This makes them water-, oil- and heat-resistant — and almost impossible to break down in nature, hence "forever chemicals". Origin: PFAS have been in use for decades; PTFE (Teflon) was discovered in 1938. Uses: non-stick cookware, stain- and water-repellent textiles, food packaging, firefighting foams (AFFF), coatings and industrial processes. Behaviour: persistent, mobile in water, and bioaccumulative — they build up in blood and organs. Long-chain vs short-chain: long-chain PFAS (e.g., PFOA, PFOS) are more bioaccumulative; short-chain substitutes are more mobile and harder to filter. Precursors: compounds that transform into stable PFAS over time — often missed by fixed testing lists. How PFAS Reach the Tap Figure 5 — PFAS pathway: from source to human exposure The C–F bond resists natural degradation, so PFAS persist at every stageSourcesWaste streamsWater bodiesTreatment plantExposureindustry, coatings,foams, textilessewage, landfillleachaterivers, coast,groundwaterconventional stepsdo not remove PFASdrinking water,food, dustChennai: 8 target PFAS were5–103% higher after treatmentVisakhapatnam: sewage ≈ 41%of median coastal PFAS Treatment designed for microbes and sediment cannot capture PFAS; unidentified precursors may even convert into stable PFAS inside the plant. What the Indian Studies Found Chennai (IIT-Madras, 2024): 14 samples from groundwater, surface water and four stages of a treatment plant; the highest levels were in residential wells near garbage dumps, and treated water carried 5–103% more of the eight target PFAS than raw water. Visakhapatnam (GITAM with Canadian and US partners, 2026): of 77 PFAS tested in seawater and sewage, 38 were detected; sewage contributed about 41% of median coastal concentrations. Multi-State review (2025): across Gujarat, Maharashtra, Tamil Nadu and West Bengal, contamination is a legitimate concern, but differing test methods leave its national extent poorly defined. Toxicology (2026): a mixture of 24 PFAS delayed hatching, slowed growth and reduced heart rates in zebrafish. Health Risk and Global Standards Detection alone does not establish risk, which depends on the type of PFAS, dose, duration and route of exposure. Exposure has been linked to effects on the liver, thyroid, immune response and foetal development. The IARC classifies PFOA as carcinogenic to humans (Group 1) and PFOS as possibly carcinogenic (Group 2B). 4 ng/LUS EPA limit, PFOA & PFOS each (2024) 0.1 µg/LEU, sum of 20 PFAS (from 2026) NoneIndia, IS 10500:2012 Stockholm Convention on POPs (2001, in force 2004): PFOS listed in 2009 (Annex B, restriction), PFOA in 2019 and PFHxS in 2022 (Annex A, elimination). India is a Party, but each new listing applies to India only after it ratifies the amendment. India's regulatory gap: the Environment Ministry has said there is no specific regulation banning PFAS manufacture; there is no clear pathway to penalise polluting sources. Work under way: the BIS has a Working Group on Emerging Contaminants and Forever Chemicals revising IS 10500; CSIR-IITR, Lucknow can detect 50 PFAS and is part of a UNEP-funded National Implementation Plan to build baseline data. Way Forward Know the inventory: map which PFAS are manufactured, imported and used in India. Harmonise monitoring: standard methods, and non-target screening (e.g., high-resolution mass spectrometry) to catch precursors beyond fixed lists. Precautionary interim limits for well-studied PFAS such as PFOA and PFOS, without waiting for complete exposure data. Avoid a named-chemical trap: regulating by class rather than individual compounds prevents substitution by untested PFAS. Treatment R&D: low-cost adsorbents; known options such as activated carbon, ion exchange and reverse osmosis remain costly at scale. ✎ Mains Practice Question ‘Forever chemicals’ pose a regulatory challenge unlike that of conventional pollutants. Discuss with reference to India's drinking-water standards and international frameworks, and suggest a roadmap for regulating PFAS. 15 marks · 250 words 06 Wild Buffalo Returns to Kanha After Nearly a Century: Madhya Pradesh Begins Reintroduction ImportantGS-III · Environment — Biodiversity Conservation, Protected AreasPrelims + MainsNews Reports Eight wild water buffaloes (six females, two males) brought from Kaziranga National Park, Assam, have been moved from a small acclimatisation enclosure into a 17-hectare enclosure in Kanha Tiger Reserve, where the species disappeared nearly 100 years ago. Figure 6 — The wild water buffalo (Bubalus arnee) Wide, backward-sweeping horns and a heavier build distinguish the wild buffalo from its domestic descendant; it depends on wet grasslands and marshes like those in Kanha's meadows. Representative image; reproduced with credit for educational use. ◈ Basics First — The Wild Water Buffalo Scientific name: Bubalus arnee — the wild ancestor of the domestic buffalo. Status: IUCN Endangered; Schedule I, Wild Life (Protection) Act, 1972. Range in India: mainly Assam (Kaziranga holds the world's largest population; also Manas, Dibru-Saikhowa), with a small, critically low population in Chhattisgarh (Udanti-Sitanadi, Indravati). State animal of Chhattisgarh. Key threats: hybridisation with domestic buffalo, disease from livestock, loss of wet grassland habitat, and poaching. Static Anchor — Kanha Tiger Reserve Located in Mandla and Balaghat districts of Madhya Pradesh, in the Maikal range of the Satpuras; sal forests interspersed with open meadows (maidans). National Park in 1955; among the first nine reserves under Project Tiger (1973). Known for saving the hard-ground barasingha (Rucervus duvaucelii branderi), MP's state animal, from fewer than 70 animals around 1970. ▤ The Reintroduction Plan Source population: Kaziranga NP, Assam. First batch: 8 animals (6 females, 2 males), now in a 17-ha enclosure. Method: soft release — small enclosure → larger enclosure → free range. Target: 50 wild buffaloes over three years (stated plan). Significance and Challenges Ecological restoration: large grazers shape grassland structure and widen the prey base for tigers. Risk spreading: a second stronghold outside Assam reduces the risk of a single catastrophic event (flood, disease) wiping out the species. Part of a trend: MP's earlier translocations include gaur to Bandhavgarh (2011–12) and cheetahs to Kuno (2022) and Gandhi Sagar (2025). Challenges: keeping the herd genetically pure by preventing contact with village buffaloes; disease screening; adequate wet grasslands; and crop-raiding conflict at the reserve's fringe. Best practice: the IUCN Guidelines for Reintroductions (2013) call for removing the original cause of extinction, assessing habitat suitability, and long-term post-release monitoring. ✎ Mains Practice Question Species reintroduction is increasingly used as a conservation tool in India. Discuss its ecological rationale and the challenges involved, with reference to recent examples. 10 marks · 150 words Internal Security & DefenceGeneral Studies Paper III 07 INS Mangrol Commissioned: Plugging the Gap in Coastal Anti-Submarine Warfare ImportantGS-III · Security — Coastal Security, Defence IndigenisationPrelims + MainsPIB · Ministry of Defence · The Indian Express The Navy commissioned INS Mangrol (P82), the third Mahe-class Anti-Submarine Warfare Shallow Water Craft (ASW-SWC), at the Naval Dockyard, Mumbai, on 12 October 2026. Built by Cochin Shipyard Ltd (CSL), it has over 80% indigenous content. Figure 7 — INS Mangrol at its commissioning, Naval Dockyard, Mumbai The ship's crest shows a crowned emblem over waves; the name revives that of an earlier INS Mangrol (M85), a minesweeper that served until April 2004. Image courtesy PIB / Indian Navy; reproduced with credit for educational use. ◈ Basics First — Why Shallow-Water ASW is Hard Submarines are detected mainly by sonar (sound navigation and ranging). In shallow coastal waters, sound reflects off the seabed and surface, thermal layers bend sound waves, and shipping and fishing noise masks targets — making the littoral the hardest zone for anti-submarine warfare. The threat: quiet diesel-electric submarines (SSKs), some with air-independent propulsion, can lurk near harbours, ports and offshore installations. Large warships such as destroyers draw too much water and are too valuable for close-in coastal hunting — hence dedicated shallow-draught craft. ▤ Ship and Programme at a Glance Programme: 16 ASW-SWCs, approved by the Defence Acquisition Council in December 2013 (about ₹13,000 crore); contracts signed in 2019 — 8 by CSL (Mahe class) and 8 by GRSE, Kolkata (Arnala class). Lead ships: INS Arnala (commissioned June 2025) and INS Mahe (November 2025). Dimensions: about 78 m long, 11.36 m beam, 896–1,100 tonnes displacement. Propulsion: three diesel engine-driven waterjets — the Navy's largest warships with this system, offering manoeuvrability and lower underwater noise. Roles: ASW, underwater surveillance, search and rescue, LIMO, and mine-laying. Weapons and sensors: indigenous sonars, torpedoes and anti-submarine rockets; built to DNV classification standards. Name: Mangrol, a fishing harbour in Junagadh district, Gujarat. Figure 8 — INS Mangrol (P82) underway at sea A low, compact 78-m hull with a tall integrated mast; waterjet propulsion leaves no exposed propellers, aiding manoeuvrability and lowering underwater noise in shallow coastal waters. Image courtesy PIB / Indian Navy; reproduced with credit for educational use. Why It Matters Capability gap: the four Abhay-class corvettes that handled coastal ASW were decommissioned between 2017 and 2025; the 16 SWCs replace them with a much larger force. Coastline to protect: India's revised coastline is 11,098.81 km, with 12 major ports (and Vadhavan under development as the 13th) and 184 minor ports.
