Proposal to Ban Social Media Use by Children: Federal and Digital Governance Issues

---

I. Context

• The governments of Karnataka and Andhra Pradesh have proposed restrictions on social media use by minors to address rising concerns about mental health, online abuse, and excessive mobile phone usage among children.
• Karnataka proposes a ban for children below 16 years, while Andhra Pradesh plans restrictions for children below 13 years, with possible regulations for the 13–16 age group.
• Andhra Pradesh has indicated that the policy may be implemented within a 90-day timeline.

Relevance

• GS Paper II – Polity & Governance
  • Federalism and division of legislative powers between Union and States.
  • Regulation of digital platforms under IT Act, 2000 and IT Rules 2021.
• GS Paper II – Social Justice
  • Child protection, mental health, and online safety.

Practice Question

Q. State governments proposing restrictions on social media use by minors raise questions of child protection, digital rights, and federal legislative competence. Examine the constitutional and governance challenges associated with regulating children’s social media access in India. (250 words)

II. Rationale Behind the Proposed Ban

1. Mental Health Concerns

• Studies indicate that excessive social media exposure among adolescents contributes to anxiety, depression, sleep disorders, and attention deficits.
• Children are particularly vulnerable to cyberbullying, online grooming, and harmful content exposure.

2. Digital Addiction

• Growing smartphone penetration has led to increased screen time among minors, affecting academic performance, physical activity, and social interaction.

3. Protection from Harmful Content

• Social media platforms expose minors to misinformation, explicit content, online harassment, and algorithm-driven addictive behaviour patterns.

III. Legal and Constitutional Issues

Regulation of Internet: Union Domain

• Regulation of the internet, digital platforms, and intermediaries largely falls under Union jurisdiction, governed by central legislation such as:
  • Information Technology Act, 2000
  • Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021
• Since these frameworks are created under central laws, a state-level ban may raise questions of legislative competence and constitutional validity.

Possible Federal Overlap

• States may justify restrictions using powers related to:
  • Public order
  • Public health
  • Child welfare
• However, once the regulation directly affects digital intermediaries or internet services, it may encroach upon the Centre’s legislative domain.

 IV. Implementation Challenges

Technological Enforcement

• Enforcing age-based bans requires robust age verification systems, which remain technologically challenging and may raise privacy concerns.

Jurisdictional Issues

• Most social media platforms operate as global digital intermediaries, making enforcement across borders difficult.

Household-Level Regulation

• Monitoring children’s access to social media at home or through personal devices may be practically difficult to enforce.

V. International Precedent

Australia’s Social Media Law

• In December 2025, Australia became the first country to legislate a social media ban for children below 16 years.
• The law requires platforms to implement strict age verification systems, with penalties up to $32 million for repeated violations.
• However, the law remains controversial due to limited empirical evidence on its effectiveness and concerns about digital rights.

 VI. Arguments Supporting the Ban

Child Protection

• Age-based restrictions may protect minors from online harassment, harmful content, and digital exploitation.

Mental Health Benefits

• Reduced social media exposure could improve psychological well-being, attention span, and academic focus among children.

Regulation of Big Tech

• The measure may push technology companies to design safer digital environments for minors.

VII. Criticism and Concerns

Freedom of Expression

• Critics argue that blanket bans may restrict children’s right to information, expression, and participation in digital spaces.

Implementation Feasibility

• Experts suggest that such bans may become “paper rules” with limited enforcement capacity, making compliance difficult.

Root Cause Issues

• Digital rights groups argue that the problem lies more with platform design, addictive algorithms, and weak data protection frameworks rather than children’s access alone.

VIII. Alternative Policy Approaches

Digital Literacy and Awareness

• Introducing digital safety education in schools can help children learn responsible technology use.

Parental Control Mechanisms

• Platforms can introduce stronger parental control systems and age-appropriate content filters.

Platform Accountability

• Social media companies should strengthen content moderation, child protection policies, and algorithm transparency.

Regulatory Framework

• India may consider a comprehensive child online safety law, similar to regulations in other countries.

IX. Governance Significance

• The debate highlights tensions between child protection, digital rights, and federal legislative powers.
• It also reflects growing concerns globally about the impact of social media on children’s mental health and development.

Prelims Pointers

• IT Act governing digital platforms: Information Technology Act, 2000.
• Australia social media ban age: below 16 years.
• Penalty under Australian law: up to $32 million for repeated violations.
• Proposed ban age: Karnataka <16, Andhra Pradesh <13.

Karnataka Links Liquor Tax to Alcohol Content (ABV-based Taxation)

---

I. Context

• In a first-of-its-kind reform in India, the Karnataka government has proposed linking liquor taxation directly to alcohol content (Alcohol by Volume – ABV) under its Excise Policy announced in the 2026–27 Budget.
• The reform aims to modernise the state excise structure, simplify pricing slabs, improve transparency, and align taxation with public health considerations.
• The new ABV-based taxation system will be implemented from April 2026, making Karnataka the first Indian state to adopt alcohol-content-based taxation.

Relevance

• GS Paper III – Economy
  • State taxation systems and excise revenue.
  • Fiscal policy tools to influence consumption patterns.
• GS Paper II – Governance
  • State powers under State List (Entry 51 – excise duty on alcoholic liquor).

Practice Question

Q. Taxation policy can be used as a public health instrument. Examine the rationale and implications of alcohol-content-based taxation (ABV-based taxation) in regulating alcohol consumption in India. (250 words)

II. What is Alcohol by Volume (ABV)?

• Alcohol by Volume (ABV) is a global standard measurement that indicates the percentage of ethanol present in an alcoholic beverage.
• For example:
  • Beer: typically 4–8% ABV
  • Wine: around 10–15% ABV
  • Whisky/Spirits: generally 36–50% ABV
• Higher ABV means higher alcohol concentration, which is associated with greater health risks and social externalities.

III. Key Features of the New Tax Framework

1. ABV-Based Excise Duty

• The excise duty will now be directly linked to the alcohol content of beverages, ensuring that stronger alcohol products attract higher taxes.
• The system targets alcohol as the primary source of negative externalities, rather than taxing beverages uniformly.

2. Reduction of Tax Slabs

• The number of price-based taxation slabs will be reduced from 16 to 8, simplifying the taxation structure and improving pricing transparency.

3. Gradual Implementation

• The government plans to phase the reform over four years, ensuring gradual price adjustments and minimal disruption to markets.

4. Impact on Prices

• Beer and wine may become cheaper, as they typically contain lower alcohol content compared to distilled spirits.
• High-strength alcoholic beverages such as whisky and strong spirits are likely to face higher taxation.

IV. Economic Significance

Excise Revenue

• The Karnataka government has set an ambitious excise revenue target of ₹45,000 crore for the next financial year, making liquor taxation a major source of state revenue.
• State excise duties on alcohol constitute one of the largest own tax revenue sources for Indian states, as alcohol is outside the GST framework.

Ease of Doing Business

• Simplified taxation slabs aim to improve regulatory clarity for liquor manufacturers, breweries, and retailers, reducing administrative complexity.
• Industry stakeholders believe the reform could encourage premiumisation and investment in the alcohol sector.

V. Public Health Rationale

• The ABV-based taxation model is globally recognised, recommended by organisations such as the World Health Organization as an effective alcohol control strategy.
• Higher taxes on stronger alcohol can discourage excessive consumption and reduce alcohol-related harm, including:
  • Alcohol addiction
  • Road accidents
  • Domestic violence
  • Public health burdens

VI. Global Practice

• Several countries already follow ABV-based alcohol taxation, including:
  • United Kingdom
  • Australia
  • European Union member states
• These systems tax ethanol content directly, creating a more rational taxation framework aligned with health outcomes.

VII. Concerns and Challenges

Industry Adjustment

• Liquor manufacturers may need to adjust product pricing and formulations, potentially affecting supply chains and retail markets.

Consumer Behaviour

• There is a risk that price-sensitive consumers may shift toward cheaper high-alcohol beverages, depending on pricing dynamics.

Implementation Complexity

• Accurate measurement of ABV levels and enforcement of taxation categories will require strong regulatory oversight and testing infrastructure.

IX. Governance and Policy Significance

• The reform reflects a broader shift toward evidence-based alcohol policy, combining public health objectives with fiscal efficiency.
• If successful, Karnataka’s model could influence other Indian states to adopt alcohol-content-based taxation frameworks.

Prelims Pointers

• ABV: Alcohol by Volume (percentage of ethanol in beverages).
• Beer ABV: typically 4–8%.
• Whisky ABV: typically 36–50%.
• Liquor taxation: outside GST, falls under state excise powers (Entry 51, State List).

RBI Proposal: Zero Liability for Customers in Case of Lender Negligence

---

I. Context

• The Reserve Bank of India (RBI) has proposed zero liability for bank customers in cases where digital banking fraud occurs due to negligence by banks or lenders, strengthening consumer protection in the digital financial ecosystem.
• The proposal forms part of the “Review of Framework of Limiting Customer Liability in Unauthorised Electronic Banking Transactions”, reflecting the rapid growth of digital payments, fintech platforms, and online banking transactions in India.
• The new framework is expected to apply to electronic banking transactions conducted on or after 1 July 2026, once the guidelines are finalised.

Relevance

• GS Paper III – Economy
  • Digital payments ecosystem and financial consumer protection.
  • Banking regulation and cybersecurity risks.
• GS Paper II – Governance
  • Role of Reserve Bank of India in regulating banking and payment systems.

Practice Question

Q. With the rapid expansion of digital payments in India, consumer protection against cyber fraud has become critical. Discuss the significance and challenges of the RBI’s proposal for zero liability in cases of bank negligence. (250 words)

II. Key Provisions of the Proposed Framework

Zero Liability for Customers

• Customers will have zero liability if unauthorised digital banking transactions occur due to negligence or lapses by the bank, regardless of whether the fraudulent transaction was reported by the customer immediately.
• In such cases, the bank must reverse the entire unauthorised transaction amount, ensuring customers are fully compensated for the financial loss.

Limited Liability in Certain Cases

• If fraud occurs without bank negligence but is reported promptly by the customer, compensation may be limited to 85% of the net loss or ₹25,000 (whichever is lower) as a one-time compensation during the customer’s lifetime.

Mandatory Reporting Requirement

• Customers must report fraudulent transactions to:
  • National Cyber Crime Reporting Portal
  • National Cyber Crime Helpline (1930)
  • Concerned bank or financial institution
• The fraud must generally be reported within five days of the transaction to claim compensation.

III. Definition of Bank Negligence

Under the draft framework, bank negligence may include:

• Failure to maintain adequate cybersecurity systems and safeguards for electronic banking transactions.
• Failure to send mandatory alerts or notifications for transactions.
• System malfunctions, security breaches, or internal frauds within banking institutions.
• Inadequate fraud detection mechanisms or risk management protocols.

IV. Rationale for the Reform

Growth of Digital Payments in India

• India has become the largest digital payments ecosystem globally, with UPI transactions exceeding 12 billion monthly transactions (2025 estimates).
• Rapid digitisation has increased cyber fraud risks, phishing attacks, identity theft, and unauthorised digital transactions.

Need for Consumer Protection

• Customers often lack technical knowledge to prevent sophisticated cyber fraud, making stronger institutional accountability necessary.
• The proposed framework shifts responsibility toward banks and financial institutions that control digital infrastructure and security systems.

V. Governance and Regulatory Significance

• The framework reinforces the RBI’s role as the primary regulator of banking system stability, consumer protection, and payment system security under the RBI Act 1934 and Banking Regulation Act 1949.
• It complements national initiatives such as Digital India, financial inclusion, and expansion of digital payment systems like UPI, AEPS, and mobile banking.
• By ensuring stronger safeguards, the policy aims to enhance trust in digital banking and strengthen financial system credibility.

VI. Challenges and Concerns

Implementation Issues

• Banks must significantly upgrade fraud detection algorithms, real-time monitoring systems, and cybersecurity infrastructure to prevent misuse.

Operational Burden on Banks

• Increased compensation liability could raise operational costs and compliance burdens for financial institutions.

Risk of Moral Hazard

• Some analysts argue that guaranteed compensation might reduce customer vigilance, potentially increasing fraud attempts.

VII. Way Forward

Strengthening Cybersecurity Infrastructure

• Banks must deploy AI-based fraud detection, behavioural analytics, and multi-factor authentication systems to reduce cyber risks.

Financial Literacy and Awareness

• Nationwide campaigns should improve digital financial literacy, fraud awareness, and cyber hygiene practices among users.

Improved Inter-agency Coordination

• Strong coordination between RBI, banks, fintech companies, and cybercrime agencies is essential to investigate and prevent digital fraud.

Prelims Pointers

• National Cyber Crime Helpline: 1930
• Regulator of digital banking framework: Reserve Bank of India (RBI)
• Effective date of proposed framework: 1 July 2026
• Compensation limit in limited liability cases: 85% of net loss or ₹25,000 (whichever lower)

Black Death and Biodiversity: Rethinking Human–Nature Relationships

---

I. Context and Background

• The Black Death (1347–1353) was a devastating bubonic plague pandemic caused by Yersinia pestis, killing 30–50% of Europe’s population, leading to massive abandonment of farms, villages, and cultivated landscapes.
• This demographic collapse triggered a historical “rewilding event”, where previously cultivated land reverted to forests and unmanaged vegetation due to the sudden withdrawal of human agricultural activity.
• Conventional ecological theory often assumes human presence negatively impacts biodiversity, suggesting that reduced human activity would naturally produce more diverse and pristine ecosystems.
• However, a recent University of York study published in the journal Ecology Letters (2026) challenges this assumption by analysing long-term plant biodiversity trends before and after the Black Death.

Relevance

• GS Paper III – Environment
  • Biodiversity conservation and ecosystem management.
  • Role of human activities in shaping ecological systems.
• GS Paper I – Geography
  • Human–environment interaction and cultural landscapes.

Practice Question

Q. The relationship between human activity and biodiversity is complex and context-dependent. Discuss how historical ecological evidence challenges the assumption that reduced human presence always improves biodiversity. (250 words)

II. Key Findings of the Study

• Contrary to expectations, the study found that plant biodiversity significantly declined during the 150 years following the Black Death, despite the widespread abandonment of agricultural land.
• Researchers analysed historical ecological datasets, pollen records, and plant species distribution patterns across Europe to reconstruct biodiversity trends across pre- and post-pandemic landscapes.
• When farmland was abandoned, traditional land management practices such as grazing, crop rotation, and clearing ceased, allowing dense forests to expand rapidly.
• The spread of uniform forest cover reduced habitat diversity and ecological niches, causing a decline in plant species that depended on open or semi-managed landscapes.
• Biodiversity recovery began only after human populations rebounded and agricultural activities resumed, a process that took nearly 300 years to restore pre-plague biodiversity levels.

III. Ecological Interpretation

• Many plant species in European ecosystems evolved under long-term human disturbance regimes, including farming, grazing, burning, and periodic land clearing.
• These disturbances create heterogeneous landscapes with varied habitats, supporting species that require open grasslands, transitional zones, and agricultural margins.
• When human activity stopped abruptly after the Black Death, landscapes shifted toward monotonous forest ecosystems, reducing ecological complexity and species diversity.
• Thus, biodiversity loss occurred because habitat heterogeneity declined, not because ecosystems were damaged by human withdrawal.

IV. Implications for Environmental Theory

• The study challenges the assumption that ecosystems untouched by humans are always the most biodiverse, questioning the idealised notion of “pristine wilderness”.
• It suggests that in many regions, biodiversity has historically developed within human-modified landscapes, shaped by centuries of traditional agricultural practices.
• Human–nature interactions can therefore be mutually reinforcing rather than inherently destructive, particularly when land management practices are sustainable.
• This supports the concept of “Anthropocene biodiversity”, where biodiversity patterns are influenced by human cultural landscapes and ecological stewardship.

V. Relevance for Modern Conservation Strategies

Debate on Rewilding

• The findings have implications for the growing “rewilding movement”, which advocates removing human activity from landscapes to allow ecosystems to recover naturally.
• While rewilding can restore ecological processes in some regions, the study suggests that complete human withdrawal may not always enhance biodiversity.
• Many ecosystems require active management and disturbance regimes to maintain species diversity and habitat variety.

Landscape Mosaic Approach

• Researchers recommend adopting a “patchwork landscape approach”, where different land uses coexist to support diverse ecosystems.
• Such landscapes include croplands, woodlands, grasslands, wetlands, ponds, and pastures, creating multiple ecological niches and microhabitats.
• This approach enhances ecosystem resilience, species richness, and sustainable land use practices.

VI. Examples of Balanced Human–Nature Landscapes

• Traditional agro-ecosystems such as Iberian Dehesas and Montados combine trees, grazing livestock, and crop cultivation, supporting high biodiversity and sustainable livelihoods.
• Alpine pasture systems maintain species-rich grasslands through seasonal grazing and traditional farming practices.
• The Hungarian Tanya system, a dispersed agricultural settlement model, integrates small-scale farming with natural ecosystems, preserving biodiversity.
• These systems demonstrate that sustainable human land use can coexist with and even enhance biodiversity.

VII. Broader Environmental Significance

• The study highlights the importance of human stewardship in shaping biodiversity-rich landscapes, challenging simplistic narratives of human–nature conflict.
• Sustainable agricultural practices can promote ecosystem services such as pollination, soil fertility, and carbon sequestration.
• Integrating traditional ecological knowledge and modern conservation science is essential for maintaining balanced socio-ecological systems.
• This perspective aligns with contemporary environmental frameworks such as nature-based solutions and sustainable land management.

Prelims Pointers

• Black Death: Bubonic plague pandemic between 1347–1353, caused by Yersinia pestis.
• Estimated mortality: 30–50% of Europe’s population.
• Study published in Ecology Letters (2026) by University of York.
• Key concept: Biodiversity depends on habitat heterogeneity, not merely absence of human activity.
