  • [12th March 2026] The Hindu OpED: A seismic decision: On revision to India’s earthquake zoning, rollback 

    PYQ Relevance[UPSC 2021] Discuss about the vulnerability of India to earthquake related hazards. Give examples including the salient features of major disasters caused by earthquakes in different parts of India during the last three decades.Linkage: It highlights India’s seismic vulnerability and the need for accurate hazard assessment. The revision of the earthquake zoning framework and adoption of probabilistic seismic hazard assessment strengthen disaster preparedness and risk mapping.

    Mentor’s Comment

    The rollback of the Bureau of Indian Standards (BIS) revision of India’s earthquake zoning framework has revived debate over seismic risk assessment. The proposed revision sought to replace the simplified fixed seismic zoning model with probabilistic seismic hazard assessment, a method widely used globally. It also introduced a new high-risk Zone VI covering vulnerable regions such as Kashmir and the Himalayan belt. However, stricter zoning raised economic concerns, as construction costs could increase by about 20% with a one-zone rise and nearly one-third with two zones

    Why does India require a revised earthquake zoning framework?

    1. Urban Expansion and Risk Exposure: Rapid urbanisation increases population and infrastructure in seismically vulnerable areas. Large infrastructure such as metro systems, dams, highways, and power stations require updated seismic design standards.
    2. Disaster Preparedness: Accurate zoning enables safer city planning, infrastructure design, and disaster management strategies. It reduces casualties and economic losses during earthquakes.
    3. Climate and Disaster Resilience: Earthquake-resilient infrastructure contributes to broader climate-resilient development and sustainable cities.
    4. Infrastructure Protection: Critical infrastructure projects must incorporate seismic design standards to prevent catastrophic failure during earthquakes.

    What is the current earthquake zoning system in India?

    1. Fixed Zoning Model: India currently uses a simplified seismic zoning map, dividing the country into fixed categories based on historical seismic activity.
    2. Seismic Zones: India’s seismic classification includes Zones II, III, IV and V, with Zone V representing the highest risk areas.
    3. Limitations of Fixed Zoning: Fixed zones rely heavily on past earthquake records and may not fully capture future seismic probabilities or micro-level risk variations.
    4. Urban Planning Integration: These zones influence building codes, infrastructure design standards, and urban planning guidelines.

    What changes were proposed in the BIS revision?

    1. Probabilistic Seismic Hazard Assessment (PSHA): Introduces probability-based simulations to estimate earthquake intensity and frequency rather than relying solely on historical data.
    2. Introduction of Zone VI: Adds a new highest-risk seismic zone, covering Kashmir, parts of the Himalayan belt, Kutch in Gujarat, and the northeast.
    3. Improved Risk Modelling: Uses dynamic modelling of ground motion probabilities to improve earthquake preparedness.
    4. Alignment with Global Practice: Aligns India’s seismic risk assessment methodology with advanced economies and seismically active regions worldwide.

    Why did the proposed revision face opposition?

    1. Economic Cost: Construction costs could rise significantly.
      1. One-zone increase: Costs may rise by around 20%.
      2. Two-zone increase: Costs may rise by nearly one-third.
    2. Infrastructure Cost Escalation: High-value projects such as metro systems, dams, and power stations may face substantially higher structural design costs.
    3. Development Concerns: Urban planners fear stricter zoning could slow infrastructure development in economically fragile regions.
    4. Housing Informality: Nearly 80% of India’s housing stock lies in the informal sector, raising concerns that stricter regulations may increase unregulated construction.

    What are the broader governance and policy challenges?

    1. Institutional Coordination: The proposal faced resistance from multiple agencies including Ministry of Housing and Urban Affairs, Home Affairs, Central Water Commission, and National Dam Safety Authority.
    2. Policy Consultation Gap: Large regulatory changes require extensive consultation across government agencies, industry stakeholders, and technical experts.
    3. Balancing Safety and Affordability: Stricter building standards improve safety but increase construction costs and housing affordability pressures.
    4. Implementation Capacity: Enforcement challenges remain significant due to informal housing markets and limited regulatory capacity.

    How does the debate intersect with climate and sustainability goals?

    1. Construction Sector Emissions: The construction sector is among the largest dispersed sources of carbon emissions in India.
    2. Infrastructure Lifecycle: Seismic-resilient structures reduce the need for reconstruction after disasters, lowering long-term carbon and economic costs.
    3. Resilient Urban Development: Disaster-proof infrastructure supports climate adaptation strategies and sustainable urbanisation.

    Conclusion

    Revising India’s earthquake zoning framework remains essential for ensuring disaster-resilient urban growth and infrastructure safety. However, scientific improvements must be accompanied by broad institutional consultation, economic feasibility assessments, and strong implementation mechanisms. A balanced framework that integrates advanced risk modelling with practical governance capacity is critical for strengthening India’s long-term disaster resilience.

  • A revision of GDP and its implications

    Why in the News?

    India’s National Statistical Office (NSO) has released a new GDP series with 2022-23 as the base year, revising earlier national income estimates. The revision reduces the absolute size of India’s GDP by around 3-4% compared with estimates based on the 2011-12 base year and introduces changes in sectoral and institutional shares of output.

    What is Gross Domestic Product (GDP)?

    1. Gross Domestic Product (GDP): Measures the total monetary value of all final goods and services produced within the geographical boundaries of a country during a specific period, usually one year.
    2. Indicator of Economic Performance: Serves as the primary measure of economic size, growth rate, and overall economic activity used in national and international comparisons.

  • Starship Delays May Affect NASA’s Moon Landing Timeline

    Why in the News

    A report by NASA’s Inspector General warns that delays in SpaceX Starship could affect the timeline of the Artemis Program, which aims to land humans on the Moon before 2030.

    Background: Artemis Moon Mission

    • NASA is working with private companies like SpaceX and Blue Origin
    • The Artemis programme aims to establish sustainable human missions to the Moon and eventually support missions to Mars.
    • Originally, the Moon landing under Artemis III was targeted for 2024, but delays have pushed the timeline to around 2028 or later.

    Why It Is Difficult

    • Starship uses liquid methane and liquid oxygen as fuel. These must be stored at cryogenic temperatures below −150°C.
    • The system must perform multiple docking and fuel transfers in Low Earth Orbit (LEO).
    • LEO already has heavy satellite traffic, increasing operational risk.

This is so because the attraction of Earth (a) does not exist at such a distance. (b) is neutralized by the attraction of the moon. (c) provides the necessary speed for its steady motion. (d) provides the necessary acceleration for its motion.
  • [11th March 2026] The Hindu OpED: AI and the national security calculus

    PYQ Relevance[UPSC 2023] Introduce the concept of Artificial Intelligence (AI). How does AI help clinical diagnosis? Do you perceive any threat to privacy of the individual in the use of AI in healthcare?Linkage: The article discusses AI as a dual-use technology with security implications, highlighting concerns about surveillance, military integration, and governance of AI systems. The PYQ connects through debates on ethical risks, regulation, and societal impacts of AI deployment.

    Mentor’s Comment

    The rapid rise of Artificial Intelligence (AI) has pushed it from a commercial technology to a strategic national security asset. The debate intensified after American AI company Anthropic urged the U.S. government to classify Chinese AI labs like DeepSeek, Moonshot AI, and MiniMax as national security threats. The controversy reflects a deeper policy dilemma: Should AI be treated like nuclear technology requiring strict controls, or like a dual-use digital technology that thrives on open innovation? The issue has implications for military decision-making, global technological competition, and governance of autonomous systems.

    Is AI becoming a national security technology comparable to nuclear weapons?

    1. Dual-Use Technology: AI functions as a general-purpose technology used for civilian innovation and military operations. Unlike nuclear weapons, AI also drives sectors such as healthcare, finance, and digital governance.
    2. Military Integration: AI models assist in accelerating the military “kill chain”, supporting target identification, intelligence analysis, and operational decisions.
    3. Technological Diffusion: AI research occurs across universities, private firms, and open-source communities, enabling rapid global diffusion.
    4. Comparative Argument: Nuclear non-proliferation succeeds due to scarcity of fissile material, whereas AI relies on widely accessible resources like data and computing.

    What is AI model distillation and why is it controversial?

    1. Model Distillation: Distillation involves training smaller AI models using the outputs of larger frontier models to replicate capabilities at lower computational cost.
    2. Industrial-Scale Claims: Anthropic alleges 16 million interactions with its Claude model through around 24,000 accounts, suggesting systematic distillation efforts.
    3. Strategic Advantage: Distillation enables competitors to achieve frontier-level performance at a fraction of the cost of original research.
    4. Intellectual Property Issues: Companies argue distillation violates terms of service and proprietary model safeguards.

    Why are export controls and technological restrictions facing limitations?

    1. Circumvention of Restrictions: Export controls on advanced chips and inputs often face workarounds through alternative supply chains or domestic development.
    2. Human Capital Mobility: AI researchers frequently work across countries, making technological containment difficult.
    3. Diffusion of Knowledge: AI research spreads through academic publications, open-source models, and global conferences.
    4. Policy Ineffectiveness: Restrictions may fail to prevent competitors from achieving comparable performance, as illustrated by emerging Chinese AI models.

    Do corporate guardrails effectively regulate military uses of AI?

    1. Corporate Governance Limits: Private companies can modify or remove safeguards when responding to government contracts.
    2. Defense Integration: AI firms increasingly compete for military and national security contracts, accelerating integration into defence systems.
      1. Example: Some firms accept permissive contracts allowing military use of AI models, illustrating the competitive pressure in defence technology markets.
    3. Regulatory Gap: Corporate policies alone cannot substitute state-led governance frameworks for military AI use.

    Why does AI governance require international cooperation?

    1. Inevitable Military Adoption: Armed forces globally are integrating generative AI into surveillance, cyber warfare, and autonomous systems.
    2. Need for Global Norms: Effective regulation requires plurilateral commitments among states rather than unilateral corporate decisions.
    3. Human Control: Governance frameworks must ensure meaningful human oversight in lethal decision-making systems.
    4. Restrictions on Mass Surveillance: Global norms should prohibit large-scale civilian surveillance enabled by AI systems.

    Way Forward: Strengthening Global Governance of AI in National Security

    1. Multilateral AI Governance Framework: Establishes global rules for responsible AI deployment through platforms like the United Nations and the UNESCO which already adopted the Recommendation on the Ethics of Artificial Intelligence (2021) promoting transparency, accountability, and human rights protection.
    2. AI Safety and Risk Management Regimes: Strengthens international cooperation through initiatives like the Global Partnership on Artificial Intelligence (GPAI) and the OECD AI Principles, which promote responsible AI innovation, democratic values, and safeguards against misuse.
    3. Regulation of Military AI Systems: Develops binding norms on autonomous weapons through negotiations under the United Nations Convention on Certain Conventional Weapons (CCW), focusing on meaningful human control over lethal autonomous weapons systems (LAWS).
    4. Global Technology Export and Monitoring Mechanisms: Expands export-control regimes such as the Wassenaar Arrangement to include AI algorithms, advanced chips, and surveillance systems to prevent uncontrolled proliferation.
    5. Data Governance and Digital Rights Protection: Aligns AI regulation with frameworks such as the European Union AI Act, which classifies AI systems by risk level and restricts high-risk surveillance technologies.
    6. International Research Collaboration: Promotes open but secure collaboration among states, universities, and companies through forums like the G20 and World Economic Forum, ensuring innovation while maintaining safeguards.
    7. India’s Strategic Role: India can leverage platforms such as the BRICS, Quad, and G20 to push for ethical AI standards, responsible military use, and inclusive technological governance.

    Conclusion

    Artificial Intelligence is transforming the intersection of technology, geopolitics, and national security. Unlike nuclear technology, AI cannot be easily contained due to its open research ecosystem, global talent mobility, and digital diffusion. Effective governance therefore requires international norms, state-led oversight, and responsible corporate practices to balance innovation with security.

  • Development means expansion of choices in Amartya Sen’s ‘capabilities approach’

    Why in the News?

    The debate on development has increasingly shifted from income growth to human freedom. This increases the relevance of the Capability Approach developed by Amartya Sen, especially in an era marked by AI-driven economic change, weakening democratic deliberation, and rising economic reductionism. According to this approach, development must be understood as an expansion of human capabilities and freedoms, rather than merely economic growth indicators such as GDP.

    What is the Capability Approach developed by Amartya Sen?

    1. The Capability Approach, articulated by Amartya Sen, redefines development as the expansion of substantive freedoms that enable individuals to lead lives they value. 
    2. The framework challenges the dominance of purely economic indicators such as GDP or per capita income, emphasizing human agency, equality of autonomy, and access to social opportunities.

    What Is the Core Idea Behind Amartya Sen’s Capability Approach?

    1. Capabilities: Represents the substantive freedoms individuals possess to lead lives they value. Unlike traditional development metrics, it focuses on opportunities available to individuals rather than economic output.
    2. Functionings: Denotes the actual achievements or states of being, such as being educated, healthy, or socially active.
    3. Freedom-centred development: Defines development as expansion of real freedoms, not merely accumulation of wealth.
    4. Human agency: Positions individuals as active agents of development rather than passive beneficiaries of economic growth.

    Why Does the Capability Approach Challenge Economic Reductionism?

    1. GDP limitations: GDP measures economic production but ignores inequality, well-being, and access to opportunities.
    2. Human-centred evaluation: Evaluates development based on education, health, autonomy, and participation rather than only income growth.
    3. Policy implications: Encourages governments to invest in social infrastructure such as education, healthcare, and democratic institutions.
    4. Intellectual influence: Inspired global frameworks such as the Human Development Index (HDI) developed by the United Nations Development Programme.

    How Did Amartya Sen’s Collaboration with Mahbub ul Haq Transform Development Measurement?

    1. Human Development paradigm: Collaboration between Amartya Sen and Mahbub ul Haq reshaped development thinking.
    2. Human Development Index: Introduced by the United Nations Development Programme to measure development through health, education, and income indicators. In 1990, the pair introduced the HDI as an alternative to GDP. The index, which Haq championed and designed, measures average achievement across three key dimensions: health (life expectancy), knowledge (education), and standard of living (income).
    3. Redefining “Poverty”: Their work transformed the definition of poverty from a simple lack of income to a broader “capability deprivation”.
    4. Policy shift: Encouraged global policy discourse to move beyond income-centric growth models.
    5. Normative foundation: Positioned human dignity and opportunity expansion as the core objective of development.
      1. Challenging Economic Consensus: The collaboration successfully challenged the World Bank-IMF consensus that focused almost exclusively on macroeconomic growth. They argued that growth is only a means to development, not the end goal itself, and that “people are the wealth of nations”

    Why Are Capabilities Often Reduced to Employability in Modern Policy Discourse?

    1. Skill-centric education: Increasing emphasis on skills for employment rather than holistic human development.
    2. Labour-market orientation: Education policies often prioritise market demand over critical thinking and civic participation.
    3. Instrumental approach: Capabilities are treated as tools for economic productivity instead of intrinsic human freedoms.
    4. Policy challenge: Requires balancing economic productivity with intellectual freedom and democratic participation.

    How Do Declining Democratic Standards Affect the Capability Framework?

    1. Erosion of critical thinking: Post-truth politics weakens reasoned debate and evidence-based policy making.
    2. Shrinking civic space: Reduces individuals’ ability to participate meaningfully in democratic governance.
    3. Institutional weakening: Declining governance standards limit the state’s ability to nurture enabling conditions for capabilities.
    4. Impact on development: Development becomes economic growth without empowerment.

    What Is the Concept of Equality of Autonomy in Sen’s Thought?

    1. Equality of autonomy: Emphasizes that individuals must have equal capability to pursue their chosen life paths.
    2. Justice framework: Links capability expansion to broader theories of justice and fairness.
    3. Institutional role: Requires both formal institutions and lived social experiences to enable human freedom.
    4. Democratic participation: Ensures individuals can think independently, reason critically, and contribute to society.

    Conclusion

    The capability approach reframes development as the expansion of human freedoms, opportunities, and agency. In a rapidly transforming world shaped by technological disruption and democratic challenges, the framework reminds policymakers that economic growth without empowerment is incomplete development. Sustainable progress requires strengthening education, public reasoning, social equity, and democratic participation, ensuring that development truly expands the choices and freedoms available to people.

    PYQ Relevance

    [UPSC 2023] The crucial aspect of the development process has been the inadequate attention paid to Human Resource Development in India. Suggest measures that can address this inadequacy.

    Linkage: This question links to Amartya Sen’s Capability Approach, which views development as expansion of human capabilities through education, health, and skill formation, rather than mere GDP growth. It is also relevant to GS-2 (Social Justice) themes such as human development, poverty alleviation, and strengthening social sector outcomes.

  • Behind an early summer is a lack of winter rains

    Why in the News?

    An unusual surge in temperatures across north and north-western India during February-March has raised concerns about shifting seasonal patterns. Several regions recorded temperatures 8-13°C above normal, bringing heat-wave-like conditions weeks before the usual onset of summer. The phenomenon has been linked to deficient winter rainfall and weak Western Disturbances, which are critical for regulating winter climate in north India. 

    Why is India witnessing unusually high temperatures early this year?

    1. Temperature Anomaly: Several regions recorded temperatures 8-13°C above normal, reaching heat-wave-like conditions in February-March.
    2. Early Heat Conditions: Warm weather replaced cool winter days earlier than usual in northern and western India.
    3. Rare Occurrence: A similar situation occurred three years ago, but such an early onset of summer remains relatively uncommon.
    4. Regional Evidence:
      1. Shimla: 25.3°C (March 2026, highest recorded till March 8).
      2. Pahalgam: 22.7°C.
      3. Gulmarg: 17.2°C.
      4. Srinagar: 24.7°C.

    Climatological Significance: Heat waves are generally uncommon in high-altitude regions such as Shimla in March.

    How did weak Western Disturbances influence the winter climate?

    1. Western Disturbances: East-moving rain-bearing weather systems originating beyond Iran and drawing moisture from the Mediterranean Sea and other water bodies.
    2. Seasonal Importance: These systems normally bring winter rainfall and snowfall across northern India.
    3. Deficiency Since November 2025: Reduced frequency and intensity of Western Disturbances led to lower winter precipitation.
    4. IMD Observation: Meteorologists noted lack of wind convergence between westerly and easterly winds, reducing moisture transport into north and central India.
    5. Temperature Regulation: Winter precipitation normally moderates temperatures by maintaining soil moisture and atmospheric cooling.

    Why was the winter of 2026 considered unusually dry?

    1. Rainfall Deficit: All-India rainfall during January-February was only 16 mm, which is 60% below normal.
    2. Historical Context: February 2026 became the third driest February since 1901.
    3. Snowfall Decline: Both snowfall and rainfall remained subdued across Himalayan regions.
    4. Meteorological Cause: Persistent lack of favourable weather systems during winter months.

    How does a dry winter accelerate the onset of summer?

    1. Soil Moisture Deficit: Reduced rainfall leaves soil dry and unable to moderate temperature increases.
    2. Evaporation Mechanism: Moist soils normally evaporate moisture before heating up, delaying temperature rise.
    3. Rapid Surface Heating: Dry soils heat faster, increasing land surface temperature and accelerating summer conditions.
    4. Climate Feedback: Dry land conditions amplify regional warming and heat stress.

    What are the implications for agriculture and water resources?

    1. Impact on Rabi Crops: Sudden temperature spikes affect mustard, wheat, gram, groundnut, sesame, sorghum, and sunflower.
    2. Horticulture Stress: Crops such as potatoes and apples may suffer due to heat stress.
    3. Irrigation Demand: Farmers have been advised to increase irrigation frequency to maintain soil moisture.
    4. Water Resource Pressure: Increased irrigation demand may strain local groundwater and water reserves.

    What do temperature records indicate about changing climatic patterns?

    1. Temperature Extremes: High temperatures in Himalayan regions during early March indicate increasing climate variability.
    2. Comparison with Past Years:
      1. 2026: Shimla 25.3°C, Pahalgam 22.7°C, Gulmarg 17.2°C, Srinagar 24.7°C.
      2. 2025: Shimla 24.4°C, Pahalgam 20.4°C.
      3. 2024: Shimla 24.8°C.
    3. Climate Signal: Frequent anomalies suggest greater unpredictability in seasonal transitions.

    Conclusion

    The early onset of summer in India highlights the critical role of winter rainfall and Western Disturbances in maintaining seasonal balance. Reduced precipitation has accelerated land heating and increased agricultural vulnerability. Strengthening climate monitoring, improving irrigation management, and integrating seasonal forecasting into agricultural planning are essential to mitigate the impacts of such climatic anomalies.

    PYQ Relevance

    [UPSC 2017] Climate Change’ is a global problem. How will India be affected by climate change? How will Himalayan and coastal states of India be affected?

    Linkage: The early onset of summer due to weak winter rains and Western Disturbances reflects climate variability affecting Himalayan regions, highlighting changing temperature and precipitation patterns.

    • 12,351 alerts issued between Jan 2024 and Oct 2025.
    • Average alerts per month: 561
    • Alerts increased to 1,028 per month during Nov–March, when deforestation peaks.

    Why Alerts Were Stopped

    • According to FSI officials:
      • The system was only a pilot project.
      • The government is currently reviewing feedback from states on its usefulness.
      • Active monitoring reportedly stopped in January 2026.

    Comparison with Global Systems

    • The system was considered similar to Terra‑I, used in countries like Peru. However, Anavaran had higher spatial resolution:
      • 10–20 metre resolution (Sentinel satellites)
      • Terra-I: 250 metre resolution

  • 250 Years of The Wealth of Nations: Adam Smith’s Lessons

    Why in the News

    The famous economics book An Inquiry into the Nature and Causes of the Wealth of Nations completed 250 years on March 9, 2026. The work by Adam Smith continues to influence debates on free trade, taxation, monopolies, and economic inequality.

    About The Wealth of Nations

    • Published in 1776, during the Scottish Enlightenment.
    • Considered the foundational text of classical economics.
    • Analyses the sources of national wealth, labour productivity, trade, and markets.
      • Smith is often called the “father of modern economics”.

    Key Economic Ideas of Adam Smith

    • Division of Labour: Specialisation improves productivity.
      • Example used by Smith: pin factory, where each worker performs a specific task to increase output.
    • Free Markets: Economic activity works best when individuals pursue self-interest within competitive markets.
    • The “Invisible Hand”: Individuals pursuing their own interest can unintentionally benefit society as a whole. Markets allocate resources efficiently without heavy government intervention.
    • Free Trade: Smith criticised mercantilism, the idea that countries should maximise exports and minimise imports.
    • He argued that:
    • Trade allows nations to specialise in what they produce efficiently.
    • Greater trade leads to mutual prosperity.
    [2011] What does the term “economic liberalization” refer to in the context of the Indian economy? (a) Expansion of the public sector (b) Restriction of foreign investment (c) Removal of restrictions on private sector and encouragement of free market policies (d) Increase in trade barriers
