Formation of Fog, Meaning, Types, Process, Impacts in India

Formation of Fog

Formation of Fog is a common atmospheric phenomenon formed when water vapour condenses near the Earth’s surface due to cooling and saturation conditions. It develops under specific combinations of temperature, humidity and wind patterns, often during calm nights. Fog behaves like a low lying cloud and shows high spatial variability depending on local factors such as moisture availability, terrain and proximity to water bodies, making it an important element of weather systems.

What is Fog?

Fog is a visible suspension of tiny water droplets or ice crystals in the air near the ground that reduces visibility to less than 1 kilometre. It forms when air becomes saturated either by cooling to the dew point or by adding moisture. Unlike clouds, fog occurs at ground level and is strongly influenced by local sources like soil moisture, rivers and surface cooling processes.

Fog Types

Different fog types are classified based on their formation mechanisms, temperature conditions and movement of air masses across surfaces.

  • Radiation Fog: Forms during clear nights when the Earth loses heat rapidly through radiation, cooling the air near the surface to the dew point. It is common in plains and usually dissipates after sunrise.
  • Advection Fog: Develops when warm, moist air moves horizontally over a colder surface, leading to cooling and condensation. It is widespread, long lasting and often seen in coastal and large plain regions.
  • Valley Fog: Occurs when cold, dense air settles in valleys and gets trapped due to surrounding topography. It remains for longer durations because the cold air cannot escape easily.
  • Freezing Fog: Forms when supercooled water droplets freeze upon contact with surfaces at temperatures below 0°C, leading to ice deposition on objects like trees, roads and power lines.
  • Evaporation Fog: Develops when water vapour is added to cold air through evaporation, such as when cold air passes over warm water bodies, causing saturation and condensation.
  • Upslope Fog: Occurs when moist air is forced to rise along slopes of hills or mountains, cooling adiabatically and forming fog over elevated terrains.
  • Hail Fog: A rare type formed after hailstorms when melting hail cools the surrounding warm, moist air to its dew point, producing shallow and localized fog.
  • Ice Fog: Found in extremely cold regions where water vapour directly forms tiny ice crystals suspended in air, common in polar conditions.
  • Steam Fog: Forms when cold air moves over warmer water, causing evaporation and rapid condensation, giving a smoky appearance above water surfaces.

Formation of Fog Process

Formation of Fog is a gradual process driven by cooling, moisture saturation and atmospheric stability near the surface.

  • During the night, land loses heat through radiation, cooling the air close to the ground. This reduces the air’s capacity to hold moisture and initiates condensation conditions.
  • Presence of water vapour from rivers, soil moisture, or nearby water bodies increases humidity levels, which is essential for fog formation near the surface layer.
  • When air temperature falls close to the dew point, typically within a small margin, saturation occurs and water vapour begins to condense into tiny droplets.
  • Light or calm winds prevent mixing of air layers, allowing cooled air to remain near the surface and support stable fog formation.
  • Water vapour condenses on dust, salt, or particulate matter acting as condensation nuclei, forming visible droplets suspended in the air.
  • Fog becomes densest during early morning hours when temperature reaches its lowest level, enhancing condensation and reducing visibility significantly.
  • High humidity and low temperature together strengthen fog intensity, while variations in these factors cause spatial differences in fog density.
  • After sunrise, solar heating increases temperature, reducing relative humidity and causing evaporation of droplets, leading to gradual fog clearance.
  • Visibility Classification: According to IMD, fog is categorized as very dense (0-50 m), dense (51-200 m), moderate (201-500 m) and shallow (up to 1 km visibility).

Formation of Fog Impacts

The Formation of Fog significantly influences human activities, environmental conditions and atmospheric processes due to reduced visibility and moisture presence.

  • Transportation Disruption: Dense fog reduces visibility to near zero, increasing road accidents, delaying flights and affecting railway operations due to safety concerns.
  • Aviation Challenges: Airports require advanced landing systems as fog restricts runway visibility, often causing flight delays, diversions, or cancellations during peak fog conditions.
  • Agricultural Effects: Fog provides moisture beneficial for crops but prolonged exposure can promote fungal diseases and damage sensitive agricultural produce.
  • Air Quality Deterioration: Fog traps pollutants near the surface due to temperature inversion, worsening air quality and increasing respiratory problems in urban areas.
  • Economic Impact: Disruptions in transport, logistics and agriculture lead to financial losses and increased operational costs in multiple sectors.
  • Temperature Regulation: Fog reduces daytime heating by blocking sunlight, leading to prolonged cold conditions, especially during winter months.
  • Ecosystem Influence: Certain ecosystems depend on fog for moisture, while excessive fog may alter biodiversity patterns and ecological balance.

Formation of Fog in India

Fog formation in India is largely influenced by seasonal temperature changes, moisture sources and regional atmospheric conditions.

  • Dense fog has recently enveloped the northwestern region of India including Delhi, Punjab, Haryana, parts of Uttar Pradesh and Rajasthan due to falling temperatures and increased moisture availability.
  • Minimum temperatures significantly below normal during cold wave conditions enhance cooling of surface air, favouring fog formation across northern plains.
  • The Indo Gangetic Plain region is highly prone to fog, especially in December and January, experiencing prolonged spells lasting several weeks.
  • Storms originating in the Mediterranean Sea bring moisture bearing winds, increasing humidity levels and supporting fog formation over northwest India.
  • In absence of western disturbances, rivers, soil moisture and surface evaporation act as local contributors to atmospheric moisture.
  • Calm winds over the Indo Gangetic Plain prevent mixing of air, allowing fog to persist for longer durations during winter mornings.
  • Delhi recorded minimum temperature around 6°C, creating favourable conditions for dense fog development.
  • Fog occurrence shows seasonal variation, with some years experiencing 25 to 35 days of dense fog, while others show minimal events.

Pollution and Formation of Fog

Pollution plays a critical role in enhancing fog formation and increasing its intensity, especially in urban regions.

  • Pollutants provide particles on which water vapour condenses, increasing the likelihood and density of fog formation in polluted cities.
  • Interaction of fog with pollutants results in Smog Formation, significantly affecting visibility, health and environmental quality.
  • Due to higher pollution levels, Delhi records more fog days compared to less polluted regions, as per IMD observations.
  • Falling temperatures reduce wind speed and bring down the inversion layer, trapping pollutants and moisture within the boundary layer.
  • Temperature inversion limits upward movement of air, causing pollutants and fog droplets to remain concentrated near the surface.
  • Fog episodes coincide with severe AQI levels, as particulate matter accumulates and remains suspended within the fog layer.
  • Longer lasting advection fog leads to secondary particulate formation, causing rapid buildup of pollutants in the atmosphere.
  • With rising temperature during the day, fog disperses, improving air mixing and reducing pollutant concentration temporarily.

India’s Growth Claims, A Clash with Data Reality 

Context

  • For years, India has been celebrated as one of the fastest-growing major economies in the world, with strong GDP figures reinforcing a narrative of sustained progress.
  • However, economic realities for ordinary citizens often diverge sharply from these optimistic headlines.
  • Daily life is shaped not by growth rates but by wages, employment opportunities, inflation, and business stability. T
  • his contrast raises a fundamental question: do official economic statistics accurately reflect the lived experiences of India’s population?

Questioning GDP Estimates and Why Small Errors Matter

  • Questioning GDP Estimates

    • A recent study by Abhishek Anand, Josh Felman, and Arvind Subramanian challenges the reliability of India’s GDP data.
    • Their research suggests that economic growth since 2011 may have been overstated by approximately 1.5 to 2 percentage points annually.
  • Why Small Errors Matter

    • While this discrepancy may appear minor, its cumulative impact is substantial. Over time, even slight overestimations can significantly distort:
    • Policy decisions
    • Investment strategies
    • Public perception of government performance
    • Thus, what seems like a technical issue becomes a matter of national importance.

Structural Weakness in Economic Measurement

  • Overreliance on the Formal Sector

    • India’s GDP estimation increasingly depends on data from the formal sector, such as corporate filings and organised industry reports.
    • However, a large proportion of India’s workforce operates in the informal sector, small businesses, daily wage labour, and cash-based activities.
  • The Visibility Problem

    • This creates a structural imbalance:
    • The formal sector is easier to measure and therefore overrepresented
    • The informal sector, though larger, remains underrepresented
    • As a result, economic data may reflect what is visible rather than what is truly happening across the economy.

Disconnect Between Growth and Lived Experience

  • Despite high reported growth rates, several key indicators suggest a weaker economic reality:
  • Sluggish private investment
  • Stagnant or slow real wage growth
  • Limited job creation in manufacturing
  • Rising unemployment concerns, especially among youth
  • This disconnect has made the growth narrative increasingly difficult for citizens to relate to.

Impact of Economic Shocks

  • Major Disruptions to the Informal Economy

    • A series of economic shocks further exposed the gap between data and reality:
    • Demonetisation disrupted cash-dependent sectors
    • Goods and Services Tax increased compliance burdens on small firms
    • COVID-19 disproportionately affected informal workers
  • Statistical Blind Spots

    • Because GDP calculations rely heavily on formal-sector indicators, the damage to informal sectors may not be fully captured, masking the true extent of economic distress.

The Deeper Contradiction in India’s Growth Model

  • Rising Inequality

    • Economic growth has increasingly benefited:
      • Large corporations
      • Financial elites
    • At the same time, public welfare systems have weakened in effectiveness.
  • The Illusion of Formalisation
    • Formalisation is often presented as progress, but it can also conceal:
      • The closure of small businesses
      • Market concentration in the hands of large firms
    • While national accounts may record this as efficiency, it may actually represent economic displacement and reduced livelihood opportunities.

Concerns About Data Transparency

  • Missing and Controversial Data

    • Recent developments have raised concerns about the transparency of India’s statistical system:
      • Delay in conducting the Census
      • Non-release of the 2017–18 consumption survey
      • Controversies over unemployment data
  • Implications for Democracy

    • These patterns suggest a growing discomfort with unfavourable data, which undermines:
      • Public trust
      • Policy effectiveness
      • Institutional credibility

The Role of Statistics in a Democracy

    • Statistics are not merely tools for showcasing achievements; they are essential public infrastructure. Reliable data enables:
      • Citizens to hold governments accountable
      • Economists to design effective policies
      • Governments to identify and address emerging crises
    • Without credible statistics, economic management becomes guesswork rather than informed decision-making.

The Way Forward

  • To restore trust and accuracy in economic measurement, India must:
    • Strengthen independent statistical institutions
    • Improve methods to capture informal sector activity
    • Ensure transparency in data collection and publication
    • Avoid reliance on selective or incomplete indicators

Conclusion

  • India’s economic success cannot rest solely on impressive GDP figures. True progress must be reflected in the everyday experiences of its citizens.
  • If growth is genuine, it should withstand scrutiny and align with reality.
  • Ultimately, statistics should serve the purpose of truth, not political convenience.
  • For a country of India’s scale and ambition, credible and transparent data is not optional, it is essential for building an inclusive, resilient, and trustworthy economic future.

India’s Growth Claims, A Clash with Data Reality FAQs

Q1. What is the main concern about India’s GDP data?
Ans. The main concern is that India’s GDP growth may have been overstated, making it less reliable.

Q2. Who conducted the study questioning GDP estimates?
Ans. The study was conducted by Abhishek Anand, Josh Felman, and Arvind Subramanian.

Q3. Why is the informal sector important in this discussion?
Ans. The informal sector is important because it employs a large part of the population but is not accurately reflected in GDP data.

Q4. Name one major event that affected the informal economy.
Ans. One major event that affected the informal economy was the Demonetisation.

Q5. Why are reliable statistics important in a democracy?
Ans. Reliable statistics are important because they help citizens, policymakers, and economists make informed decisions.

A Mislabelling of a Supreme Court Handbook 

Context

  • The recent observation by the Chief Justice of India, Justice Surya Kant, that the Supreme Court’s Handbook on Combating Gender Stereotypes (2023) is technical and too Harvard-oriented has its relevance and accessibility.
  • While the emphasis on improving judicial training is undeniably important, such criticism risks overlooking the handbook’s actual purpose and contribution.
  • A closer reading shows that the handbook is neither excessively academic nor detached from Indian realities; instead, it is a practical, precedent-based tool aimed at reforming judicial reasoning and language.

Purpose and Objectives of the Handbook

  • Identifying Stereotypical Language

    • It seeks to highlight language in judicial decisions that perpetuates gender stereotypes and recommends more appropriate alternatives.
  • Challenging Faulty Reasoning

    • The handbook examines common reasoning patterns rooted in stereotypes and explains why they are legally and constitutionally flawed.
  • Compiling Binding Precedents

    • It brings together Supreme Court judgments that have already rejected such stereotypes, making them accessible in a structured format.
    • These objectives demonstrate that the handbook is not theoretical but deeply practical, designed to influence how judges write and reason in real cases.

The Role of Language in Judicial Reasoning

  • Problematic Terminology in Judgments

    • For instance, in Velusamy vs D. Patchaiammal (2010), the term ‘keep’ was used to describe a woman in a live-in relationship.
    • This expression reflects patriarchal assumptions and diminishes women’s agency.
    • Similarly, the use of the term ravished in rape cases carries outdated and moralistic undertones, shifting focus away from consent and bodily autonomy.
  • Corrective Approach of the Handbook

    • The handbook identifies such expressions and offers alternatives grounded in constitutional values like dignity and equality.
    • In doing so, it promotes more sensitive and accurate judicial communication.

Grounding in Indian Legal Context

  • Reliance on Supreme Court Precedents

    • It compiles binding decisions of the Supreme Court that reject gender stereotypes.
    • For example, it reiterates that the absence of physical injuries in sexual assault cases should not be used to discredit survivors.
  • Recognition of Survivor Realities

    • The handbook also acknowledges that there is no correct way for a survivor to behave, encouraging courts to adopt a contextual and empathetic approach.
    • This reliance on existing Indian case law underscores its practical relevance and accessibility for legal professionals.

Understanding the Intended Audience

  • Designed for Legal Professionals

    • The handbook is intended for judges and lawyers, individuals trained to interpret legal texts, evaluate evidence, and write judgments.
    • Technical language is therefore appropriate and necessary.
  • Not Meant for Laypersons

    • It is not designed as a public-facing document for survivors or the general population. Simplifying it excessively could undermine its effectiveness as a professional resource.

Scope for Improvement

  • Need for Continuous Evolution

    • Feedback from the judiciary, legal practitioners, and civil society can help improve its clarity and application.
  • Constructive Criticism over Dismissal

    • Rather than dismissing it as overly technical, stakeholders should engage with it critically to enhance its impact.

Conclusion

  • The Handbook on Combating Gender Stereotypes represents an important institutional effort by the judiciary to address the subtle ways in which bias can influence legal reasoning.
  • By focusing on language, precedent, and constitutional values, it promotes a more equitable and accountable judicial process.
  • Labelling it as technical or Harvard-oriented risks undermining its significance and the progress it embodies.
  • A more constructive approach would be to recognise its strengths while working towards its continuous improvement.

A Mislabelling of a Supreme Court Handbook FAQs

Q1. What is the main purpose of the handbook?
Ans. The handbook aims to identify and eliminate gender stereotypes in judicial reasoning and language.

Q2. Why is judicial language important according to the handbook?
Ans. Judicial language is important because it can reinforce or challenge social biases and inequalities.

Q3. On what basis is the handbook criticized as “Harvard-oriented”?
Ans. The handbook is criticized as “Harvard-oriented” due to the perception that it is overly technical and academic.

Q4. Is the handbook actually based on foreign ideas?
Ans. No, the handbook is primarily based on Indian legal precedents and Supreme Court judgments.

Q5. Who is the intended audience of the handbook?
Ans. The handbook is intended for judges and lawyers who are trained legal professionals.

India’s NDC 2035 - Balancing Climate Ambition with Energy Realities

Context:

  • India recently announced its updated Nationally Determined Contributions (NDCs) for 2030–2035 under the Paris Agreement.
  • These targets emerge amid a fragile global order marked by geopolitical conflicts, weakening multilateralism, and renewed reliance on fossil fuels by developed nations.

India’s Enhanced Climate Targets:

  • Emissions intensity reduction:

    • Emissions intensity of GDP growth has now been set at 47% reduction by 2035 (from 2005 levels) against the previous target of 45% and the actual figure of 36% already achieved.
    • Insight: Incremental gains become harder as efficiency improves, yet India is likely to overachieve.
  • Non-fossil fuel energy capacity:

    • The previous target of 50% for 2030 has already been overtaken, as the current figure is 52.5%. The target of 60% for 2035 is realistic, given a much more challenging energy outlook.
    • Key concern: Installed capacity is not equal to actual generation, as renewable energy contributes only ~20% of electricity generation currently.
    • Need: To improve grid integration, storage, and dispatch efficiency.
  • Carbon sink expansion through afforestation:

    • Against the previous target of adding 2.5-3 billion tonnes of CO2 equivalent by 2030, the current achievement is estimated to be 2.296 billion tonnes of CO2 equivalent.
    • The target for 2035 has now been set at 5-4 billion tonnes of CO2 equivalent, which appears realistic.
    • Risks: Biodiversity loss, monoculture impacts, and inclusion of plantations may undermine ecological integrity.

Adaptation - A Strategic Priority:

  • Why does adaptation matter? Even with zero emissions, climate impacts persist due to accumulated greenhouse gases.
  • Key measures:
    • Heat Action Plans (HAPs) for rising temperatures.
    • Monitoring Himalayan glaciers and Glacial Lake Outburst Floods (GLOFs).
    • Protection of Mangroves (coastal defense), marine ecosystems (fish stocks, biodiversity).
  • Regional cooperation: Collaboration with neighbours essential for Himalayan ecosystem monitoring, and maritime ecological security.

Clean Energy Transition Pathways:

  • Green hydrogen:

    • India’s green hydrogen mission holds great promise in meeting the twin challenge of climate change and energy security.
    • Challenge: Currently, hydrogen is a byproduct from petrochemical production, so its generation is carbon intensive.
    • Solution: Hydrogen can be produced through electrolysis, but whether this process uses fossil energy or renewable energy will determine how “green” and clean hydrogen can be as a fuel.
  • Nuclear energy push:

    • The government has set an ambitious target of 100 GW of nuclear power by 2047, coinciding with the Viksit Bharat target, against the current installed capacity of only 8 GW.
    • Policy support:
      • The SHANTI Act 2025 opens this hitherto sensitive sector to the private sector, permitting up to 49% FDI in nuclear power generation.
      • It has also amended the liability clause in the existing legislation to bring it in line with international practice.
      • Promotes Small Modular Reactors (SMR) [200-250 MW capacity currently under development], providing decentralised and distributed power.

Structural Challenge - Energy Poverty:

  • India's annual per capita electricity consumption is 1,460 KWh as against a world average of 3,800 KWh.
  • The challenge lies in significantly increasing this consumption but in as ecologically sustainable a manner as possible.

Global Context and Constraints:

  • Meagre climate finance: Less than $100 billion a year (developed countries promised $100 billion a year since the Paris Agreement).
  • Challenges: This meagre climate finance will be further squeezed under the impact of war, incipient inflation and competing demands of national security and relief from economic distress.
  • Need: The world needs to recognise that energy transition requires resources that are limited in the absence of international support.

Key Challenges for India:

  • Domestic: Bridging the gap between capacity and generation. Ensuring ecological integrity in afforestation. Scaling clean technologies affordably. Managing energy transition with limited resources.
  • External: Lack of adequate climate finance. Weak global cooperation mechanisms. Pressure on developing countries to bear disproportionate burden.

Way Forward:

  • Policy and technology: Invest in energy storage, smart grids, and transmission. Promote truly green hydrogen via renewables. Accelerate SMR-based nuclear expansion.
  • Ecological balance: Prioritise natural forests over plantations. Strengthen coastal and marine ecosystem protection.
  • Adaptation and resilience: Scale up HAPs nationwide. Enhance disaster preparedness (GLOFs, cyclones).
  • Diplomacy and cooperation: Push for climate justice and finance accountability. Strengthen regional climate cooperation frameworks.

Conclusion:

  • India’s updated NDCs present a credible and balanced climate strategy, tackling the twin challenges of climate change and energy security with its own limited resources, and navigating the dual imperatives of development and sustainability.
  • India’s approach offers a pragmatic model for the Global South, but without robust international support, the transition risks being slower and more uneven.

Q2. Why is there a gap between renewable energy capacity and actual generation in India? Ans. The gap arises due to intermittency and storage constraints, limiting the effective contribution of renewables to energy security.

Q3. What is the role of adaptation in India’s climate strategy?

Ans. Adaptation is crucial as climate impacts persist despite mitigation, necessitating measures like Heat Action Plans and disaster preparedness.

Q4. What is the potential of green hydrogen and nuclear energy in India’s clean energy transition?

Ans. Green hydrogen and nuclear energy offer scalable, low-carbon solutions to balance energy security with climate goals.

Q5. What are the challenges posed by energy poverty in achieving India’s climate targets?

Ozempic vs Olymviq: Trademark Dispute Between Novo Nordisk and Dr Reddy’s

Ozempic vs Olymviq

Ozempic vs Olymviq Latest News

  • Novo Nordisk, the Danish pharma company behind the popular drug Ozempic (used for weight loss and diabetes), has been trying to protect its product from competition. 
  • After failing to win patent infringement cases against Indian generic companies, it filed a trademark case in the Delhi High Court against Dr Reddy’s Laboratories.
  • Novo Nordisk argued that Dr Reddy’s drug name “Olymviq” was too similar to “Ozempic” and could cause confusion. 
  • Following this, Dr Reddy’s agreed in court to stop further manufacturing and selling the drug under the name “Olymviq” for now.

Dr Reddy’s Semaglutide Launch and Branding Strategy

  • Dr Reddy’s Laboratories (DRL) launched its semaglutide drug under the brand name ‘Obeda’ on March 21, specifically for treating type-2 diabetes.
    • Semaglutide is a medicine used to treat type 2 diabetes and is also prescribed for long-term weight management in people with obesity.
  • DRL had plans to market the same drug under two other names: Olymviq; Mashlo. 
    • These were not disclosed during the initial announcement.

Trademark Applications and Legal Developments

  • DRL had first applied for the ‘Olymviq’ trademark in July last year, but it faced objections. 
  • Later, it filed fresh trademark applications recently and also applied for the logo earlier in March 2026, indicating continued efforts to secure the brand name.

Unclear Positioning of Olymviq

  • While Novo Nordisk markets Ozempic specifically for weight loss, DRL has not clearly disclosed the intended use of its Olymviq brand — whether for diabetes, weight loss, or another condition. 
  • The company has only stated that Olymviq is part of its broader semaglutide portfolio without further details.

Novo Nordisk’s Trademark Argument Against Dr Reddy’s

  • Novo Nordisk told the Delhi High Court that Dr Reddy’s use of the name “Olymviq” infringes its “Ozempic” trademark. 
  • It argued that “Ozempic” is a unique, invented word, and “Olymviq” is deceptively similar in sound, potentially causing confusion and unfairly leveraging its brand.

Deceptively Similar Trademarks in Pharmaceuticals

  • The Supreme Court laid down key principles to assess “deceptive similarity” in drug trademarks in the 2001 Cadila Healthcare case (Falcigo vs Falcitab). 
  • It rejected the argument that prescription-only drugs are less likely to cause confusion, noting that even small mistakes in medicines can have serious health consequences.

Stricter Standards for Drug Trademarks

  • Recognising that “drugs are poisons, not sweets,” the Court set a lower threshold for confusion in pharmaceutical trademarks compared to other goods. 
  • It highlighted India’s varied healthcare infrastructure and the risk of human error, making strict safeguards necessary.
  • The Court established criteria such as phonetic similarity, visual resemblance, and similarity in the nature and use of drugs to assess whether trademarks could cause confusion among consumers or healthcare providers.

Continued Judicial Application

  • Courts have consistently followed the Cadila ruling. In 2023, the Bombay High Court reiterated that even the slightest chance of confusion in medicinal products is sufficient to restrict the use of a similar trademark.

What is Permissible in Drug Trademarks

  • Under Section 13 of the Trademarks Act, International Non-Proprietary Names (INNs)—standard global names for drug ingredients—cannot be monopolised, as they are generic and non-proprietary in nature.
  • Use of INN-Derived Names - Pharmaceutical companies are allowed to derive brand names from INNs, provided the names are clearly distinguishable and not deceptively similar to existing trademarks.
  • Judicial Interpretation and Example - In a 2022 Delhi High Court case (Letroz vs Letero), both derived from the INN “Letrozole,” the court ruled there was no deceptive similarity. It noted that specialised doctors, like oncologists, are unlikely to confuse such drugs despite similar prefixes.

Novo Nordisk’s Fight to Protect Its Semaglutide Portfolio

  • Novo Nordisk’s drugs Ozempic and Wegovy have driven strong global sales, but the company now faces declining growth due to the expiry of patent protections in several countries, including India.
  • The company has filed multiple cases in India accusing generic manufacturers, including Dr Reddy’s Laboratories (DRL), of patent infringement. 
  • However, it has seen limited success. Courts allowed DRL to manufacture and export generic semaglutide, and this decision was upheld by the Delhi High Court shortly before the patent expired.
  • Novo Nordisk is also facing legal challenges to the validity of its now-expired patent for injectable semaglutide, further weakening its position in India.
    • With injectable patent protection expired, Novo Nordisk is now focusing on protecting its oral semaglutide drug, Rybelsus, launched in India in December 2025 just months before patent expiry.
  • In a related case, DRL assured the Delhi High Court that its tablet formulation does not fall within the patented range of Rybelsus, as the composition differs in terms of salts used, potentially avoiding infringement.

Gender Wage Gap in India – Insights from PLFS 2025

Gender Wage Gap

Gender Wage Gap Latest News

Gender Wage Gap in India

  • The Gender Wage Gap refers to the difference in earnings between men and women for similar work or across sectors. 
  • In India, this gap reflects structural inequalities in employment opportunities, skill access, and labour market participation.
  • Nature of the Wage Gap
    • Women earn less than men across all job categories.
    • The gap varies by type of employment, such as salaried jobs, casual labour, and self-employment. 
    • Informal sector dominance and occupational segregation worsen the disparity. 
  • Causes of Wage Inequality
    • Lower female labour force participation. 
    • Concentration of women in low-paying and informal jobs. 
    • Limited access to education, skills, and capital. 
    • Social norms and unpaid care responsibilities. 
  • Significance
    • Reducing the gender wage gap is essential for inclusive economic growth.
    • It enhances household incomes, boosts productivity, and improves gender equality outcomes.

News Summary

  • The PLFS 2025 data presents a mixed picture of progress and challenges in India’s labour market, particularly with respect to gender-based wage disparities.
  • Employment Levels
    • About 61.6 crore people were employed in India in 2025.
    • Male workers: 41.6 crore. 
    • Female workers: 20.0 crore. 
    • This indicates a significant gender gap in overall employment levels.
  • Higher Wage Growth for Women
    • According to the data, women’s wages grew faster than men’s across all job categories in 2025.
    • Salaried jobs: Women’s wages grew by 7.2% compared to 5.8% for men. 
    • Self-employment: Women’s earnings rose by 8.8%, slightly higher than men’s 8%. 
    • Casual labour: Women’s wages increased by 5.4%, while men’s wages declined marginally by 0.2%. 
    • This indicates a positive trend in wage growth for women, suggesting gradual improvements in labour market conditions.
  • Persistent Wage Inequality
    • Despite faster growth, the wage gap remains substantial.
    • In salaried jobs, women earned only 76% of male earnings. 
    • In casual labour, women earned 69% of male wages. 
    • In self-employment, women earned just 36% of what men earned. 
    • This highlights that higher growth rates are not sufficient to bridge the existing disparity.
  • Changes in Employment Structure
    • The survey also shows improvements in the nature of employment.
    • The share of women in salaried jobs increased to 18.2% in 2025 from 16.6% in 2024. 
    • Self-employment among women declined, indicating a shift toward better-quality jobs. 
    • Casual labour participation also increased slightly. 
    • Salaried jobs are considered more secure as they provide social security benefits and a stable income.
  • Overall Labour Market Trends
    • The broader labour market indicators also show gradual improvement.
    • Rural unemployment declined to 2.4% from 2.5%. 
    • Urban unemployment fell to 4.8% from 5%. 
    • Youth unemployment declined to 9.9% from 10.3%. 
    • However, female youth unemployment increased slightly, indicating persistent gender-specific challenges.
  • Labour Force Participation
    • Labour force participation trends present a mixed picture.
    • Rural LFPR declined slightly to 62.8%. 
    • Urban LFPR remained stable at 52.2%. 
    • A decline in LFPR suggests that fewer individuals, especially in rural areas, are actively seeking employment.
  • Informal Sector Concerns
    • The data also reflects slowing momentum in the informal sector.
    • Wage growth in the informal sector was only 3.9% in 2025. 
    • Job creation slowed significantly, with fewer establishments being added. 
    • Since a large proportion of women are employed in the informal sector, this has important implications for gender equality in earnings.
