Introduction
Intensifying planetary warming is altering mid-latitude weather dynamics, making atmospheric rivers (ARs) critical drivers of extreme precipitation beyond the tropics. Recognised by NOAA and NASA Earth Observatory, these long, moisture-laden air corridors are reshaping flood regimes across western North America, Europe and parts of East Asia.
Geographical conditions generating atmospheric rivers
• Strong moisture transport from warm ocean basins: Atmospheric rivers originate over subtropical oceans where high evaporation supplies abundant water vapour, forming concentrated corridors of Integrated Water Vapour Transport (IVT). Eg: NOAA defines ARs as long, narrow regions transporting most poleward moisture outside the tropics; the “Pineapple Express” carries moisture from Hawaii to California, intensifying winter storms.
• Interaction with mid-latitude westerlies and cyclones: ARs form ahead of cold fronts in extratropical cyclones, where pressure gradients funnel moisture poleward within the westerly wind belt. Eg: According to NASA Earth Observatory, ARs commonly develop along frontal zones in the North Pacific storm track, linking tropical moisture to mid-latitude depressions.
• Orographic uplift along western continental margins: When ARs encounter coastal mountain ranges, forced uplift causes rapid condensation and intense rainfall. Eg: The Sierra Nevada (USA) and Coastal Mountains of British Columbia amplify rainfall during AR landfall events, as observed during February 2024 storms in California (USGS imagery).
• Jet stream alignment and atmospheric blocking: A persistent jet stream configuration or blocking high can steer and stall ARs over specific regions, prolonging rainfall duration. Eg: During the November 2021 British Columbia floods, successive ARs stalled over the Fraser Valley, causing record rainfall (official provincial reports, 2021).
Implications for flood risks in mid-latitude regions
• Extreme short-duration precipitation and flash floods: ARs deliver rainfall equivalent to months of average precipitation within days, overwhelming drainage systems. Eg: California AR events (2023–24) triggered flash flooding and urban inundation, with the National Weather Service issuing excessive rainfall alerts.
• Rain-on-snow events and rapid snowmelt: Warm AR systems raise the snow line, accelerating snowmelt and compounding runoff volumes. Eg: February 2024 AR in California elevated freezing levels to nearly 10,000 feet, increasing downstream flood risks (regional weather reports).
• Landslides and geomorphic instability: Saturated slopes in mountainous mid-latitude terrains lead to debris flows and landslides. Eg: During the 2021 British Columbia floods, heavy AR rainfall caused landslides that disrupted major highways and supply chains.
• Climate change amplification of hydrological extremes: A warmer atmosphere holds more moisture as per the Clausius–Clapeyron relationship, increasing AR intensity and variability. Eg: Studies referenced by NOAA and IPCC AR6 (2021) note projected increases in AR precipitation intensity over western coasts in a warming climate.
Conclusion
Atmospheric rivers exemplify how changing circulation patterns are redistributing global precipitation extremes. Strengthening early warning systems, watershed planning and climate-resilient infrastructure in mid-latitude regions is essential to manage this evolving hydrological risk.

Introduction
Megadeltas such as the Ganga-Brahmaputra-Meghna, Nile, and Mekong represent some of the most densely populated and productive landscapes on Earth. Their apparent stability reflects a fragile dynamic equilibrium between fluvial, marine and tectonic forces, which is increasingly destabilised by climate change and human interventions.
Geomorphic processes shaping major deltas
• Fluvial sediment deposition and accretion: Rivers transport and deposit sediments as velocity declines near the mouth, forming distributaries and promoting delta progradation. The balance between sediment supply and basin accommodation determines delta morphology. Eg: The Ganga-Brahmaputra system, as per Central Water Commission (CWC) assessments, carries extremely high sediment loads that continually reshape the Sundarbans deltaic islands, leading to alternating phases of accretion and erosion.
• Marine processes and tidal reworking: Waves, tides and longshore currents redistribute sediments, influencing delta shape and shoreline stability. Tide-dominated deltas exhibit extensive mudflats and estuarine features. Eg: The Mekong delta, influenced by strong tides from the South China Sea, undergoes continuous sediment reworking, as documented in UNEP coastal ecosystem reports, altering channel patterns and coastal profiles.
• Subsidence and sediment compaction: Natural compaction of deltaic sediments and tectonic subsidence lower land levels over time, making deltas geomorphologically dynamic and prone to relative sea-level rise. Eg: The Mississippi delta, according to studies by the US Geological Survey (USGS), has experienced sustained subsidence contributing to wetland loss and land shrinkage.
• Avulsion and channel migration: Periodic shifting of river channels redistributes sediments across the delta plain, maintaining geomorphic balance over long timescales. Eg: The historical course changes of the Kosi river in the Ganga basin illustrate avulsion processes that have reconfigured floodplains and altered deltaic sediment distribution.
Factors contributing to ecological fragility
• Reduced sediment supply due to upstream dams: Large dams trap sediments, weakening natural replenishment processes and enhancing coastal erosion. Eg: Construction of dams in the Mekong basin, as highlighted in World Bank river basin assessments, has reduced sediment flow to the delta, accelerating shoreline retreat.
• Relative sea-level rise and climate change: Thermal expansion and glacier melt increase sea levels, intensifying saline intrusion and permanent inundation risks in low-lying deltas. Eg: The IPCC Sixth Assessment Report (2021) identifies low-lying megadeltas like the Ganga-Brahmaputra among the most vulnerable to sea-level rise and storm surges.
• Land subsidence due to groundwater extraction: Excessive groundwater withdrawal accelerates anthropogenic subsidence, amplifying flood vulnerability. Eg: Studies in the Mekong delta show significant subsidence linked to groundwater extraction, as reported in regional hydrological research cited by UNESCO water studies.
• Mangrove degradation and land-use change: Conversion of wetlands and mangroves for aquaculture and urban expansion reduces natural buffers against cyclones and tidal surges. Eg: The Sundarbans, recognised as a UNESCO World Heritage Site, have experienced mangrove degradation, weakening coastal protection against cyclones like Amphan (2020).
Adaptive strategies for sustainable delta management
• Integrated coastal zone management (ICZM): Coordinated planning across river basins and coastal zones ensures balanced sediment management and ecological conservation. Eg: India’s Integrated Coastal Zone Management Project, supported by the World Bank, promotes sustainable shoreline management and mangrove restoration in deltaic states.
• Ecosystem-based adaptation: Restoration of mangroves and wetlands enhances natural resilience against sea-level rise and storm surges. Eg: Mangrove afforestation initiatives in the Sundarbans under national coastal programmes have strengthened bio-shields against cyclonic impacts.
• Sediment management and controlled flooding: Allowing controlled flooding and sediment redistribution can counter subsidence and land loss. Eg: The Mississippi River restoration programmes in the United States use sediment diversions to rebuild wetlands, as documented by the US Army Corps of Engineers.
• Climate-resilient infrastructure and community adaptation: Elevated housing, saline-resistant crops and early warning systems reduce human vulnerability in delta regions. Eg: Climate adaptation measures in the Bangladesh delta, supported by multilateral agencies, include raised embankments and community-based cyclone shelters.
Conclusion
Megadeltas embody a dynamic balance between land-building and land-losing forces, now severely strained by anthropogenic pressures. Sustainable management rooted in ecosystem restoration and climate-resilient planning is essential to secure their future as both ecological and human lifelines.

Introduction
India’s constitutional secularism is premised on principled engagement rather than strict separation between State and religion. The judiciary’s evolution of the Essential Religious Practices (ERP) doctrine has significantly shaped the balance between Articles 25–26 and the guarantees of Articles 14, 15 and 21.
Whether the essential religious practices test undermines secularism and religious autonomy
• Arguments supporting the statement
• Judicial theological adjudication: The ERP test compels courts to determine what is “essential” to a religion, effectively assuming a theological role inconsistent with secular constitutionalism. Eg: In Sastri Yagnapurushadji v. Muldas Bhudardas Vaishya (1966), the Supreme Court interpreted Hindu scriptures to determine denominational identity, reflecting judicial engagement with doctrinal content rather than constitutional limits.
• Curtailment of denominational autonomy: By subjecting practices to judicial certification of essentiality, the doctrine restricts the autonomy guaranteed under Article 26(b) to manage religious affairs. Eg: In Indian Young Lawyers Association v. State of Kerala (2018), the majority held that Ayyappa devotees did not constitute a separate denomination, narrowing denominational protection.
• Conditional equality protection: Constitutional protection becomes dependent on essentiality rather than on compatibility with fundamental rights, potentially diluting dignity-based scrutiny. Eg: The Sabarimala majority prioritised Articles 14 and 25 rights of women, illustrating how essentiality can conflict with equality jurisprudence.
• Inconsistent secular reasoning: Different benches have applied ERP differently, leading to doctrinal unpredictability and undermining neutral constitutional adjudication. Eg: Variations between Shirur Mutt (1954) and later rulings reveal inconsistent thresholds for determining essentiality.
• Arguments against the statement
• Shield against excessive state control: The ERP test protects core religious practices from unwarranted State interference, preserving pluralism. Eg: In Commissioner, Hindu Religious Endowments v. Sri Lakshmindra Thirtha Swamiar (Shirur Mutt, 1954), the Court held that essential religious matters are immune from State regulation under Article 26.
• Facilitates social reform: By distinguishing essential from non-essential practices, the doctrine enables reform legislation under Article 25(2)(b). Eg: In Durgah Committee v. Syed Hussain Ali (1961), the Court excluded superstitious accretions from constitutional protection to enable regulatory reform.
• Operationalises constitutional limitations: ERP helps give meaning to “public order, morality and health” limitations embedded in Articles 25 and 26. Eg: Courts have used the doctrine to assess whether practices conflict with constitutional morality.
• Maintains judicial oversight: Without ERP, courts may lack doctrinal tools to assess whether claimed practices genuinely fall within religious freedom. Eg: In temple entry and denominational disputes, courts have relied on ERP to define scope of protection before balancing competing rights.
Practical and doctrinal difficulties inherent in the test
• Absence of objective criteria: The Constitution does not define “essential,” leaving courts to develop subjective benchmarks. Eg: Divergent interpretations in Shirur Mutt (1954) and Sabarimala (2018) demonstrate lack of uniform doctrinal standards.
• Evidentiary constraints in constitutional litigation: Determination of essentiality occurs largely on affidavits without structured theological evidence. Eg: In Sabarimala review proceedings (2019 reference to nine-judge Bench), broader questions on religious freedom architecture were raised due to such limitations.
• Conflict with dignity jurisprudence: A practice may be deemed essential yet undermine equality and dignity under Articles 14 and 21. Eg: The majority in Sabarimala (2018) invalidated exclusion despite claims of custom, foregrounding dignity.
• Risk of judicial overreach: ERP centralises interpretative authority in courts, potentially reshaping religious identity rather than merely assessing constitutional compatibility. Eg: Judicial scrutiny of denominational status in Sabarimala altered the understanding of community autonomy.
Alternative constitutional framework
• Anti-exclusion test grounded in dignity: Focus on whether a practice results in exclusion impairing equal moral membership rather than on theological essentiality. Eg: Justice D.Y. Chandrachud in Sabarimala (2018) proposed that practices causing systematic exclusion must yield to constitutional guarantees of equality and dignity.
• Application of proportionality doctrine: Adopt structured proportionality analysis to balance religious autonomy with competing fundamental rights. Eg: In K.S. Puttaswamy v. Union of India (2017), the Court affirmed proportionality as a constitutional standard for rights adjudication.
• Deference with constitutional outer limits: Recognise denominational autonomy as the starting point but intervene only where non-derogable rights are infringed. Eg: In Shayara Bano v. Union of India (2017), the Court struck down instant triple talaq as manifestly arbitrary under Article 14.
• Institutional dialogue and legislative reform: Encourage democratic reform processes alongside judicial review to reduce over-judicialisation of faith disputes. Eg: Social reform legislations enacted under Article 25(2)(b) illustrate how Parliament can address exclusion while respecting religious freedom.
Conclusion
While the essential religious practices doctrine once offered a workable filter, its theological orientation and doctrinal inconsistency have exposed structural limits. A dignity-centred, proportionality-based framework can better reconcile faith autonomy with the Constitution’s transformative promise of equal moral membership.

• Challenges in preserving autonomy: Mention issues like appointment controversies, executive influence, financial dependence and perception-based erosion of credibility.
Conclusion Conclude by stressing the need for transparent procedures and structural safeguards to ensure autonomy remains substantive and not merely formal.
Introduction
Institutional autonomy is a constitutional safeguard designed to prevent concentration of power and ensure objective decision-making. In a parliamentary democracy like India, insulation from partisan pressures is essential to preserve constitutional morality, rule of law and public trust in governance institutions.
Constitutional foundations of institutional independence
• Separation of powers under the basic structure doctrine: Although not rigidly codified, functional separation between legislature, executive and judiciary is a foundational principle upheld by the Supreme Court. Eg: In Kesavananda Bharati v. State of Kerala (1973), the Court held that the basic structure doctrine limits Parliament’s amending power, thereby protecting institutional independence as part of constitutional design.
• Judicial independence through constitutional safeguards: Security of tenure, fixed service conditions and protected removal procedures ensure insulation from executive interference. Eg: Articles 124 and 217 provide that judges of the Supreme Court and High Courts can be removed only by impeachment, and in Supreme Court Advocates-on-Record Association v. Union of India (1993), judicial primacy in appointments was affirmed.
• Independent constitutional bodies with protected status: The Constitution establishes bodies with autonomy to prevent partisan capture in critical democratic functions. Eg: Article 324 vests superintendence of elections in the Election Commission of India, and in T.N. Seshan v. Union of India (1995), the Supreme Court upheld its independent constitutional authority.
• Financial autonomy and charged expenditure: Certain institutions are insulated through financial provisions to reduce executive control. Eg: Expenditure of bodies like the Comptroller and Auditor General under Article 148 is charged on the Consolidated Fund of India, limiting parliamentary manipulation of finances.
• Directive principle promoting judicial-executive separation: The Constitution explicitly mandates functional separation at the subordinate level. Eg: Article 50 directs the State to separate judiciary from executive in public services, reinforcing structural autonomy.
Challenges in preserving autonomy in practice
• Appointment processes and perceived executive influence: Delays and disagreements in appointments may create friction affecting perceived independence. Eg: Ongoing debates over the collegium system and Memorandum of Procedure, as reflected in recent judicial observations in 2022–2023, highlight tensions between judiciary and executive regarding appointments.
• Financial and administrative dependence: Despite constitutional safeguards, many statutory and regulatory bodies depend on executive allocations and staffing. Eg: The Second Administrative Reforms Commission (2007) recommended clearer financial autonomy mechanisms for regulatory institutions to prevent subtle executive influence.
• Post-retirement appointments and conflict of interest concerns: Movement of officials to executive positions may raise questions about institutional neutrality. Eg: Public debates around post-retirement appointments of constitutional functionaries have led to demands for a statutory cooling-off period, reflecting concerns about maintaining credibility.
• Public perception shaped by political discourse: Persistent partisan criticism or narratives can erode trust even if legal independence exists. Eg: Observations in S.P. Gupta v. Union of India (1981) emphasised that independence of judiciary is essential not only in fact but also in public perception.
• Legislative changes altering service conditions: Amendments affecting tenure or removal procedures of statutory bodies may impact autonomy. Eg: The Supreme Court in Madras Bar Association v. Union of India (2021) struck down provisions affecting tribunal tenure, reaffirming that independence cannot be compromised through structural changes.
Conclusion
Institutional autonomy is not merely a constitutional formality but a democratic necessity that sustains accountability and public trust. Strengthening transparent appointments, financial insulation and ethical safeguards will ensure that independence remains substantive rather than symbolic.

Introduction
Reliable national income measurement is foundational for macroeconomic stability and policy credibility. With the Base Year 2022-23 revision, integration of GST return data into national accounts represents a structural shift toward transaction-based estimation of Gross Value Added (GVA), particularly in the private corporate sector.
Integration of GST data in refining estimation of GVA
• Transaction-based measurement of output: GST outward supply data enables estimation of value addition based on actual reported turnover instead of relying primarily on survey-based proxies like ASI. Eg: The Ministry of Statistics and Programme Implementation (MoSPI), in the Base Year 2022-23 GDP series, linked MCA corporate filings with GSTN registrations using PAN and CIN, allowing output to be apportioned based on real transaction data rather than historical allocation ratios.
• Improved corporate sector coverage: Cross-verification of MCA-listed companies with GST filings helps identify active versus inactive firms, reducing overestimation of corporate GVA. Eg: As per the revised methodology note of MoSPI (2026), firms are categorised based on GST filing status such as active filers, nil return filers and non-filers, enabling more realistic adjustment of corporate value added.
• Enhanced state-wise allocation of value added: Separate GST registrations in each state allow GVA to be distributed based on actual economic activity rather than proxy indicators. Eg: Earlier state allocation relied significantly on survey-based distribution from the Annual Survey of Industries (ASI); the revised framework uses GSTIN-level outward supply data, strengthening state-level GVA estimation.
• Strengthening quarterly GVA estimation: Monthly GST return data acts as a high-frequency indicator for sectors like trade and services, improving short-term GVA estimates. Eg: The Sub-Committee on New Data Sources under MoSPI recommended deeper use of GST data to strengthen Quarterly National Accounts (QNA) and improve advance GDP estimates.
Implications for sectoral productivity analysis
• Improved measurement of services productivity: GST data captures transaction-level information in sectors like professional services, communication and trade, improving sectoral GVA precision. Eg: Classification under SAC codes in GST returns enables more granular mapping of service output, refining productivity assessment in fast-growing services segments.
• Clearer formal sector productivity trends: Linking GST data with MCA filings strengthens the corporate sample, improving measurement of output per enterprise in the formal sector. Eg: Integration of GSTN and MCA databases allows more accurate estimation of value added within the private corporate sector in the revised GDP series.
• Granular manufacturing analysis through HSN codes: Product-level data enhances understanding of output composition and sectoral shifts within manufacturing. Eg: The MoSPI Sub-Committee recommended use of HSN-level data to develop granular short-term indicators, supporting better productivity comparisons across manufacturing industries.
• Reduced distortion from proxy-based imputations: Limiting reliance on paid-up capital or financial ratios improves the credibility of productivity estimates. Eg: Earlier imputations for non-filing firms used comparable firm ratios; cross-verification with GST reporting data reduces excessive extrapolation, leading to more realistic GVA estimates.
Associated data challenges
• Compliance-driven volatility: GST returns are compliance instruments, and changes in compliance behaviour or tax policy can affect reported turnover independently of actual output. Eg: Variations in GST filing patterns during rate rationalisation or enforcement drives may temporarily influence outward supply data, requiring statistical smoothing in national accounts.
• Coverage differences across return types: Variations in filing categories such as nil returns or delayed returns may create aggregation inconsistencies. Eg: Firms filing nil or late returns can distort short-term sectoral aggregates, as acknowledged by the MoSPI Sub-Committee on New Data Sources.
• Data-matching complexities: Accurate linkage between PAN, CIN and GSTIN identifiers is essential to prevent duplication or exclusion in corporate GVA estimation. Eg: The revised methodology relies on precise cross-referencing of MCA and GSTN databases, and mismatches can affect corporate output measurement accuracy.
• Limited coverage of informal activity: GST data largely reflects registered entities, leaving segments of the informal economy outside its ambit. Eg: Enterprises below the GST registration threshold are not fully captured in return data, necessitating supplementary surveys for comprehensive GVA estimation.
Conclusion
The integration of GST return data strengthens the precision and granularity of GVA and sectoral productivity measurement in India’s new GDP framework. Sustained statistical safeguards and transparent methodology will be essential to ensure that enhanced data integration translates into durable macroeconomic credibility.

Introduction
India’s air pollution crisis reflects not only emission intensity but also uneven measurement capacity. In a constitutional framework anchored in Article 48A and the expanded interpretation of Article 21 (Right to Life), credible and inclusive monitoring becomes central to lawful and equitable environmental governance.
Concept of hybrid monitoring networks
• Integration of regulatory and non-regulatory technologies: A hybrid network combines Continuous Ambient Air Quality Monitoring Stations (CAAQMS) with validated low-cost sensors and satellite datasets, ensuring regulatory accuracy alongside spatial expansion. Eg: The Central Pollution Control Board (CPCB) operates CAAQMS under the National Air Quality Monitoring Programme (1984–85), while cities such as Delhi have supplemented these with calibrated sensor networks to widen neighbourhood-level monitoring.
• Multi-layered data architecture: It creates a tiered framework where reference-grade monitors anchor compliance assessment and sensor grids provide hyper-local exposure mapping. Eg: Under the National Clean Air Programme (NCAP), 2019, cities have expanded monitoring near traffic corridors and industrial clusters to support targeted mitigation.
• Satellite-ground data fusion: Hybrid systems integrate satellite-based aerosol data with ground observations to improve regional pollution modelling and fill spatial gaps. Eg: ISRO’s aerosol optical depth datasets are used in conjunction with ground monitors to strengthen regional pollution assessment.
• Dynamic and exposure-based siting strategy: Hybrid networks enable flexible placement and relocation of sensors based on evolving land use and emission hotspots rather than static administrative locations. Eg: The CSE State of India’s Environment 2026 recommends exposure-based siting near schools and hospitals, reflecting the need for dynamic monitoring in expanding peri-urban areas.
Potential advantages in India
• Enhanced spatial equity: Hybrid models extend monitoring beyond metropolitan clusters to underserved peri-urban and industrial regions. Eg: The State of India’s Environment 2026 (CSE) reports that over 60% of districts lack continuous monitoring, underscoring the importance of inclusive expansion.
• Cost-effective scalability: Low-cost sensors reduce capital expenditure, enabling faster expansion compared to exclusive reliance on CAAQMS. Eg: Expansion supported by NCAP funding allows tier-II and tier-III cities to broaden coverage without the high infrastructure cost of full regulatory stations.
• Improved exposure-based governance: Greater spatial granularity supports targeted public health advisories and preventive action. Eg: In M.C. Mehta v. Union of India, the Supreme Court emphasised the State’s duty to safeguard health from pollution, which presupposes reliable exposure data.
• Strengthening evidence-based policymaking: Richer datasets enhance modelling for source apportionment, emission inventories and clean air action planning. Eg: Cities under NCAP are required to prepare action plans based on baseline pollution data, and expanded monitoring improves scientific credibility of such plans.
Operational challenges in India
• Data standardisation and calibration issues: Sensor reliability can be affected by humidity, dust and maintenance gaps, raising concerns over regulatory acceptance. Eg: CPCB mandates calibration protocols to ensure readings meet standards under the Air (Prevention and Control of Pollution) Act, 1981.
• Fragmented data governance: Air quality data are published by multiple agencies without full interoperability or a unified national platform. Eg: Separate dashboards maintained by CPCB, SPCBs and urban local bodies limit seamless integration for performance assessment under NCAP.
• Institutional capacity deficits: State Pollution Control Boards often face manpower and technical shortages affecting maintenance and validation. Eg: Parliamentary Standing Committee reports on environment have highlighted capacity constraints in SPCBs, impacting enforcement of pollution control norms.
• Financial sustainability and maintenance burden: Continuous calibration, data management and periodic replacement of sensors require sustained funding and technical expertise. Eg: Many smaller municipalities depend heavily on central assistance under NCAP, raising concerns about long-term operational viability once project funding cycles end.
Conclusion
A well-designed hybrid monitoring framework can reconcile scientific rigour with spatial inclusivity in India’s air governance. Its success, however, hinges on institutional strengthening, calibration discipline and an integrated national data ecosystem that converts monitoring into measurable public health protection.
General Studies – 4
Q7. As the Secretary of Minister of Sports in India, you introduced a ground breaking initiative called the Podium Scheme to enhance the country’s performance in international events like the Olympics. The scheme aimed to provide athletes with financial support, access to specialized training, and world-class resources. Its purpose was to nurture talent and ensure athletes could focus solely on their preparation without financial constraints. Initially, the scheme was widely praised by athletes, the media, and the public for its potential to elevate India’s standing in global sports. Over time, however, complaints began to surface, particularly from junior athletes. They alleged that the scheme disproportionately favoured senior athletes with prior international exposure. These senior athletes, already backed by numerous sponsors, were accused of misusing the benefits. Reports emerged of some senior athletes availing funds for foreign coaches and extravagant facilities but neglecting rigorous training. Junior athletes, on the other hand, argued they were being overlooked despite consistent performances at national-level events. They claimed the scheme’s focus on international achievements created a hierarchy, denying deserving young athletes the opportunity to benefit from the resources critical for their growth. A group of junior athletes brought these concerns to your attention, requesting a revision of the scheme. They proposed that beneficiaries should be selected based on recent performance at both national and international levels, ensuring meritocracy and equitable access. As the Sports Ministry Secretary, you are now faced with a dilemma. (20 M)

Introduction:
India’s performance in the recent Olympics highlights the success and drawback of initiatives like the Podium Scheme. The imbalance in resource distribution raises questions about ensuring fairness and inclusivity while sustaining such schemes’ efficacy.
Stakeholders involved in the case are:
• Senior Athletes: Beneficiaries of the scheme, accused of misuse in some cases.
• Junior Athletes: Talented individuals seeking equal access to resources.
• Sports Ministry: Responsible for policy implementation and addressing grievances.
• Coaches and Trainers: Key enablers of athlete performance, impacted by fund allocation.
• Public and Media: Observers of the scheme’s effectiveness and fairness.
• Sponsors and Investors: Financial stakeholders expecting transparent resource utilization.
• Ethical issues involved in the case are:
• Fairness in Resource Allocation: Ensuring equitable access to resources for all athletes.
• Meritocracy vs. Hierarchy: Balancing recent performance against seniority.
• Misuse of Funds: Addressing alleged misappropriation of benefits by senior athletes.
• Transparency: Ensuring accountability in fund utilization and selection processes.
• Neglect of Emerging Talent: Risk of overlooking promising junior athletes.
• Consequences of giving priority to senior athletes while ignoring juniors are:
• Negative Consequences
• Demotivation Among Juniors: Lack of opportunities discourages upcoming talent.
E.g.: Talented athletes quitting due to financial constraints.
• Stagnation in National Talent Pool: Overemphasis on seniors limits the growth of fresh talent.
E.g.: Underrepresentation in global sports categories.
• Resource Mismanagement: Misuse by seniors reduces funds available for genuine needs.
E.g.: Extravagant spending on non-essential amenities.
