Acid Rain, Causes, Mechanism, Sources, Impacts, Controlling Measures

Acid Rain

Acid Rain is an important environmental issue faced all over the world.  It not only damages the ecosystem and biodiversity but also impacts human health, cultural heritage and infrastructure. In this article, we are going to cover acid rain, its causes, process, types and impacts. 

Acid Rain

  • Acid Rain is the formation of precipitation in the form of rain, fog, mist or snow that becomes acidic because of the presence of pollutants in the atmosphere. 
  • The pollutants responsible for acid rain are sulphur dioxide and nitrogen oxides that combine with water vapour to form sulphuric acid and nitric acid. 
  • These acids then return to the Earth’s surface through rain, snow, or fog, damaging soil, water, vegetation, and man-made structures.
  • While normal rain is slightly acidic (pH around 5.6) due to dissolved carbon dioxide, acid rain has a pH much lower than this, often between 4.0–5.0.

Acid Rain Mechanism 

The cycle of acid rain works in the following manner: 

  1. Emission of Pollutants: Fossil fuel burning in industries, vehicles, and power plants releases SO₂ and NOₓ into the atmosphere.
  2. Chemical Reactions: These gases undergo oxidation and dissolve in water droplets, forming sulphuric and nitric acids.
  3. Deposition: The acids fall back to Earth in the form of rain, snow, fog, or dust, leading to acid deposition.

Acid Rain Sources 

The sources of acid rain are: 

Compound Natural Sources Anthropogenic (Human) Sources

Sulphur Dioxide

Volcanoes, oceans, decomposition of organic matter

Fossil fuel burning, coal-based power plants, industrial emissions

Nitrogen Oxides

Volcanoes, lightning, forest fires, organic decomposition

Vehicle emissions, thermal power plants, biomass burning

Formic Acid

Forest fires

Biomass burning

Carbon Dioxide

Respiration, decomposition

Fossil fuels, industrial processes

Carbon Monoxide

Plant emissions (isoprene)

Biomass burning, industries

Acid Rain Chemistry 

Acid rain causes the following reactions: 

  • Sulphur Cycle:
    • SO₂ + H₂O → H₂SO₃ (Sulphurous Acid)
    • H₂SO₃ + O₂ → H₂SO₄ (Sulphuric Acid)

  • Nitrogen Cycle:
    • 2NO₂ + H₂O → HNO₂ (Nitrous Acid) + HNO₃ (Nitric Acid)

These acids mix with rainwater and fall as acid rain.

Acid Rain Causes

Acid Rain is caused by the following factors: 

  • Burning fossil fuels in power plants, industries, and vehicles.
  • Volcanic eruptions and wildfires releasing natural SO₂ and NOₓ.
  • Industrial emissions from refineries, cement plants, and chemical factories.
  • Biomass burning and agricultural practices.

Types of Acid Deposition 

Acid Rain causes the depositions of following types: 

  1. Wet Deposition
    • Occurs when acidic pollutants combine with rain, snow, mist, or fog.
    • Common in humid regions with high precipitation.
    • Example: Acid rains in Scandinavia caused by industrial emissions in Britain.
  2. Dry Deposition
    • Occurs when acidic gases and particles settle on surfaces without precipitation.
    • Later washed off by rain, causing delayed environmental damage.
    • Common in arid or semi-arid regions with less rainfall.

Acid Rain Impacts

Following are the impacts of acid rain: 

  1. On Soil
  • Leaching of essential nutrients like calcium, magnesium, and potassium, making soil infertile.
  • Reduced microbial activity and decomposition rates.
  • Acidic soils affect crop productivity and forest health.
  1. On Vegetation
  • Reduced photosynthesis and growth rates.
  • Symptoms: Leaf discolouration, premature ageing, stunted growth, and tree death.
  • Weakens plants, making them more vulnerable to disease and pests.
  1. On Microorganisms
  • Disrupts soil microbial balance and reduces bacteria and protozoa, favours fungi.
  • Alters decomposition rates and nutrient cycling.
  • Increases susceptibility to plant and soil-borne fungal diseases.
  1. On Aquatic Life
  • Acidic waters lower pH below tolerance levels for fish and amphibians.
  • Kills eggs, sperm, and larvae of aquatic organisms.
  • Reduces plankton populations, collapsing aquatic food chains.
  • Example: Fishless lakes in Canada and Scandinavia due to acidification.
  1. On Terrestrial Life
  • Indirect effect via food chain disruption.
  • Herbivores suffer due to damaged vegetation, cascading impacts on predators.
  1. On Humans
  • Not directly harmful to touch, but indirectly impacts health.
  • SO₂ and NOₓ cause respiratory diseases like asthma, bronchitis, and lung cancer.
  • Eye, skin, and throat irritation.
  • Contributes to ground-level ozone formation, worsening air pollution.
  1. On Buildings & Monuments
  • Acid rain reacts with limestone and marble, causing structural damage.
  • Famous example: Taj Mahal (Agra) turning yellow due to acid rain and pollution.
  • Damages heritage structures, statues, and buildings worldwide.

Acid Rain Controlling Measures

Acid rain can be controlled by the following measures: 

  1. Cleaner Fuels: Use low-sulphur coal, natural gas, or renewable energy and promote solar, wind, and hydropower.
  2. Scrubbers: Installs flue-gas desulfurization units in power plants and can remove 90–95% of sulphur dioxide emissions.
  3. Catalytic Converters: Fit into vehicles to reduce NOₓ and SO₂ emissions.
  4. Neutralization: Add lime to acidic lakes and soils to restore pH balance.
  5. Policy Measures: Stricter emission standards for industries and vehicles and promotes energy efficiency and public awareness campaigns.
  6. International Cooperation: Since acid rain crosses borders, global treaties like the 1979 Geneva Convention on Long-Range Transboundary Air Pollution are crucial.

Weathering, Types, Significance, Benefits, Process Challenges

Weathering

Weathering is the breakdown of rocks, minerals and other materials at or near the Earth’s surface due to natural forces. Unlike erosion, that is the removal and transportation of materials, weathering occurs in the same place. It is caused due to climate that is temperature, rainfall and humidity, topography, biological activity and time. This process is important to the Earth system because it contributes to the formation of soil, carbon balance. Weathering helps in the fertilisation of soil, agriculture practices and landscapes maintenance. 

Weathering 

Weathering is the process of transforming rocks into soil and sediments. It is the disintegration and decomposition of rocks through mechanical, chemical and biological agents. The process helps in maintaining: 

  • Geological role: helps shape Earth's surface and creating distinctive landforms. 
  • Ecological role: releasing minerals for soil fertility and sustaining ecosystems. 

Thus, weathering is the link between the solid rocks of the lithosphere and the life-supporting soil of the biosphere.

Weathering Types 

The process of weathering can be sub-divided into three types: 

1. Physical (Mechanical) Weathering

This type of weathering involves the fragmentation of rocks into smaller particles without altering their chemical composition. It is dominant in arid and cold climates, where temperature fluctuations and freeze-thaw cycles are common.

Processes include:

  • Frost Wedging : Water enters cracks, freezes, expands, and breaks rocks apart.
  • Thermal Expansion: Heating and cooling cause rock layers to expand and contract, leading to cracking.
  • Abrasion: Rocks are worn down by wind-blown sand, moving glaciers, or flowing rivers.
  • Exfoliation: Large sheets peel off due to pressure release from overlying rocks.

2. Chemical Weathering

Chemical weathering alters the mineral composition of rocks through reactions with water, oxygen, carbon dioxide, and acids. It is most effective in warm and humid climates.

Processes include:

  • Oxidation: Reaction of oxygen with minerals like iron, producing rust.
  • Hydrolysis: Reaction of water with minerals, forming new compounds (e.g., feldspar becomes clay).
  • Carbonation: Carbon dioxide dissolved in water forms weak carbonic acid that dissolves rocks like limestone.
  • Dissolution: Minerals dissolve completely in water (e.g., salts, gypsum).

3. Biological Weathering

This type of weathering is caused by the activities of plants, animals, and microorganisms. Living organisms break down rocks either mechanically or chemically.

Examples include:

  • Plant roots penetrating cracks and widening them.
  • Lichens and microbes release organic acids that dissolve minerals.
  • Burrowing animals (earthworms, rodents) exposing rocks to air and moisture.

Weathering Significance

The process of weathering has the following significance: 

  1. Soil Formation: Weathering is the primary source of soil particles. It releases minerals like potassium, magnesium, and calcium, enriching soil fertility.
  2. Landform Development: Weathering weakens rock structures, paving the way for erosion and the creation of valleys, cliffs, caves, and plateaus. Unique features such as spires, arches, and mushroom rocks arise from differential weathering.
  3. Nutrient Cycling: Weathering ensures continuous supply of minerals to ecosystems. Nutrients released enter rivers, lakes, and soils, sustaining life cycles.
  4. Erosion and Sedimentation: Weathering provides loose material that erosion transports to form deltas, floodplains, sand dunes, and beaches.
  5. Climate Regulation: Through chemical weathering of silicates, CO₂ is consumed and stored in rocks, reducing greenhouse gas levels and stabilizing Earth’s climate.

Factors Affecting Weathering 

There are many factors affecting weathering. These include: 

  1. Climate: Extreme temperature causes physical weathering and high rainfall and humidity cause chemical weathering. Biological weathering is caused due to tropical climate. 
  2. Rock Type and Composition: Hard rocks like granite don't get affected by weathering whereas soft rocks like limestone weather quickly. Rocks that have many joints and fractures disintegrate faster. 
  3. Surface Area: Cracked rocks or smaller fragments of rocks have more surface area exposed that causes faster weathering of rocks. 
  4. Topography: Steep slopes help in physical weathering and erosion and flat regions promote water accumulation and chemical weathering. 
  5. Time: Rocks exposed for a longer time causing a higher degree of rock breakdown. 
  6. Biological Activity: Roots, burrowing animals, and microbes enhance rock disintegration.
  7. Water Availability: Extremely important for frost action, hydrolysis, carbonation, and dissolution.

Weathering Benefits

The process of weathering has the following benefits: 

  • Helps create fertile soils essential for agriculture and vegetation.
  • The process of weathering helps supply vital minerals for ecosystems.
  • Shapes diverse landscapes with ecological and aesthetic value.
  • Provides sediments like clay, sand, and gravel for construction and industries.
  • Weathered soils act as filters for groundwater.
  • Helps regulate atmospheric CO₂ through chemical processes.

Weathering Process Challenges 

Weathering Process also possesses the following challenges: 

  • Weakens rocks, leading to landslides and building deterioration.
  • Accelerates soil erosion and desertification when vegetation is removed.
  • Contributes to infrastructure damage in regions of intense weathering.

Weathering FAQs

Q1: What do you mean by weathering?

Ans: Weathering is the natural process of breaking down rocks and minerals on Earth’s surface into smaller particles by physical, chemical, or biological means.

Q2: What are the three types of weathering?

National Annual Report and Index on Women’s Safety (NARI) 2025 Latest News

The National Annual Report & Index on Women’s Safety (NARI) 2025, released recently, has shed new light through its latest report on how safe Indian cities really are for women.

About National Annual Report and Index on Women’s Safety (NARI) 2025

  • Released by the National Commission for Women, NARI 2025 offers the telling reality of the urban safety landscape. 
  • The report, a collaborative effort by the Group of Intellectuals and Academicians (GIA), Pvalue Analytics, The NorthCap University, and Jindal Global Law School, is based on a survey of 12,770 women across 31 cities in all states.

Highlights of the National Annual Report and Index on Women’s Safety (NARI) 2025

  • It placed the national safety score at 65%, categorising cities as “much above”, “above”, “below” or “much below” this benchmark.
  • Kohima, Visakhapatnam, Bhubaneswar, Aizawl, Gangtok, Itanagar, and Mumbai have emerged as the safest cities in the country for women, while Patna, Jaipur, Faridabad, Delhi, Kolkata, Srinagar, and Ranchi were ranked the lowest.
  • Kohima and other top-ranked cities were associated with stronger gender equity, civic participation, policing, and women-friendly infrastructure.
  • At the other end of the spectrum, cities like Patna and Jaipur fared poorly due to weak institutional responsiveness, patriarchal norms, and gaps in urban infrastructure.
  • Overall, six in ten women surveyed felt “safe” in their city, but 40% still considered themselves “not so safe” or “unsafe”. 
  • Prevalence of harassment remains high, with 7% women reporting at least one incident of harassment in public spaces in 2024. 
  • The highest risk group is women under 24 years of age (14% reported harassment). 
  • Verbal harassment was most common (58%), with physical, psychological, economic, and sexual harassment reported less frequently. 
  • Neighborhoods (38%) and transport (29%) were the main hotspots for harassment.

India’s Demographic Dividend as a Time Bomb

Context

  • Rabindranath Tagore once wrote, “Don’t limit a child to your own learning, for she was born in another time.”
  • These words, spoken over a century ago, hold striking relevance for India today. At a time when technology is transforming the very fabric of work and society, the nation’s education system remains tethered to outdated structures.
  • The consequence is a growing misalignment between what young Indians are taught and what the future economy demands.

The Future of Work, the Education Lag and The Demographic Dividend Paradox

  • The Future of Work, the Education Lag

    • The world of work is being reshaped by emerging technologies, with Artificial Intelligence (AI) at the forefront.
    • Research suggests that nearly 70% of jobs worldwide will be impacted by AI, with up to a third of tasks in many occupations automated entirely.
    • While this disruption is displacing traditional roles, it is also creating new opportunities in AI development, data analysis, cybersecurity, and other knowledge-intensive sectors.
    • Yet, India’s curriculum cycles remain locked in three-year updates that barely scratch the surface of this transformation.
    • Students continue to be prepared for roles that are either disappearing or radically evolving.
  • The Demographic Dividend Paradox

    • With over 800 million people under the age of 35, India possesses the largest youth population in the world.
    • In theory, this is a powerful growth engine; in practice, it has become a double-edged sword.
    • Despite producing millions of graduates each year, employability remains alarmingly low.
    • Nearly half of engineering graduates struggle to secure jobs, underscoring the widening chasm between degrees and real-world skills.
    • The numbers are stark: according to higher education leaders, 61% of curricula are not aligned with industry needs.
    • The Graduate Skills Index 2025 reveals that only 43% of Indian graduates are considered job-ready.
    • This paradox, of abundant graduates but scarce employable talent, threatens to turn the demographic dividend into a demographic time bomb.

The Crisis Begins in High School

  • A 2022 survey found that 93% of students between grades 8 and 12 were aware of only seven career options, mostly traditional professions such as doctor, engineer, or lawyer.
  • In reality, today’s economy offers over 20,000 possible career paths. Shockingly, just 7% of students reported receiving any formal career guidance.
  • This lack of awareness funnels students into degrees misaligned with both their aptitudes and market demands.
  • The India Skills Report 2024 found that more than 65% of high school graduates pursue degrees incompatible with their interests or abilities.
  • By the time they graduate, they are neither equipped with job-ready skills nor prepared for the careers of tomorrow.

Policy Attempts and Their Shortcomings

  • Recognising the crisis, the Indian government has launched numerous initiatives, from the Skill India Mission to Pradhan Mantri Kaushal Vikas Yojana and SANKALP.
  • Yet, despite heavy funding, most of these programs have fallen short of their ambitious targets.
  • Fragmentation and lack of coordination among initiatives have diluted their impact.
  • What India urgently requires is not more acronyms, but a cohesive, unified national strategy that aligns education with industry needs.
  • Collaboration between government, educational institutions, and the private sector will be key to building a robust skill-development ecosystem.

The Decisive Decade

  • India’s aspirations to be a global digital powerhouse hinge on its ability to equip youth with future-ready skills.
  • The next decade will be decisive. Failure to act risks creating a generation of literate yet unemployable citizens, a crisis that could destabilize the nation’s social fabric.
  • Historical precedents, such as the youth-led unrest during the Mandal Commission protests, remind us that disillusioned youth movements can spiral into volatility.
  • Yet, this is not an inevitable trajectory. The AI revolution, though disruptive, presents immense opportunities.
  • The World Economic Forum estimates that while automation may displace 92 million jobs in India by 2030, it will also create 170 million new ones.
  • The challenge, therefore, is not one of scarcity but of transition: preparing youth to seize emerging roles while cushioning the losses from automation.

Conclusion

  • India’s education crisis is not merely an academic or employment issue; it is a national imperative that touches upon economic growth, social stability, and the future of democracy itself.
  • To heed Tagore’s wisdom, India must stop limiting children to outdated learning; Instead, it must prepare them for the realities of their own time, a time defined by AI, global competition, and rapidly evolving career landscapes.
  • The choice is stark: convert the demographic dividend into a transformative asset, or allow it to decay into a liability.
  • The clock is ticking, and the next decade will determine which path India takes.

India’s Demographic Dividend as a Time Bomb FAQs

Q1. Why is India’s education system considered outdated today?
Ans. India’s education system is outdated because it prepares students for jobs that are either disappearing or rapidly evolving, without aligning curricula with the needs of the modern economy.

Q2. What is the demographic dividend paradox in India?
Ans. The demographic dividend paradox is that while India has the world’s largest youth population, many graduates remain unemployable due to a mismatch between education and industry needs.

Q3. At what stage does India’s skills gap begin, and why?
Ans. India’s skills gap begins in high school because most students are aware of only a handful of traditional careers and receive little to no formal career guidance.

Q4. Why have government skill-development initiatives largely failed?
Ans. Government initiatives have largely failed because they are fragmented, poorly coordinated, and unable to deliver cohesive, large-scale impact.

Q5. What decisive action must India take in the coming decade?
Ans. India must align education with industry demands, integrate future-ready skills like AI into curricula, and create a unified national strategy to prepare youth for tomorrow’s careers.

Building Health for 1.4 billion Indians

Context

  • India’s health-care system faces a dual imperative: to expand access for millions of underserved citizens while ensuring affordability in the face of rising costs.
  • Meeting this challenge demands not piecemeal solutions, but a systemic and interconnected approach, strengthening insurance, embedding prevention in primary care, leveraging digital tools, ensuring regulatory clarity, and attracting sustained investment.
  • If executed with coherence, India has the opportunity to build a health-care model that is inclusive, financially viable, and globally aspirational.

Insurance as the Foundation of Affordability

  • Risk pooling through insurance is the most effective way to make costly medical care accessible.
  • Even modest premiums can unlock significant financial protection, shielding households from catastrophic health shocks.
  • Yet, insurance penetration in India remains limited, only 15–18% of Indians are covered, with a premium-to-GDP ratio of 3.7% compared to the global average of 7%.
  • Despite this gap, the sector presents immense opportunity, with gross written premiums already reaching $15 billion in 2024 and projected to grow at over 20% annually until 2030.
  • However, affordability cannot rest solely on insurance coverage.
  • The true impact will emerge when payers, providers, and patients partner to expand coverage, integrate preventive care, and reposition insurance as a tool for everyday health security rather than merely a crisis response.

Efficiency, Scale and The Role of Government Schemes

  • Efficiency and Scale: India’s Distinct Strength

    • One of India’s unique advantages lies in its capacity to deliver quality care at scale.
    • Where medical imaging in Western countries may serve a handful of patients daily, Indian hospitals routinely maximise utilisation without diluting quality.
    • This efficiency reflects decades of innovation in workflow design, doctor-patient ratios, and infrastructure management.
    • The next frontier is extending this efficiency to underserved regions. Tier-2 and tier-3 cities, which remain at the margins of India’s health-care system, represent the true test of inclusive growth.
    • If India can replicate its urban efficiency in these geographies, it could close the access gap and set a global benchmark for how scale, innovation, and equity can converge.
  • The Role of Government Schemes

    • Schemes like Ayushman Bharat (PM-JAY) have already redefined access by covering nearly 500 million people with benefits of up to ₹5 lakh per family for advanced care.
    • The program has enabled millions of cashless treatments, with measurable outcomes such as a 90% increase in timely cancer treatments.
    • Yet the success of such schemes hinges on greater participation by private hospitals, anchored in fair reimbursements and transparent processes.
    • This would ensure both the financial viability of providers and genuine value for patients.

The Way Forward

  • Prevention as the Most Effective Cost-Saver

    • Despite progress, studies reveal that even insured families often face catastrophic out-of-pocket expenses for chronic conditions like diabetes and hypertension.
    • The solution lies in two complementary strategies: redesigning insurance to include outpatient and diagnostic care, and launching a nationwide preventive health push.
    • Prevention, however, requires public participation. Every rupee spent on healthier lifestyles saves multiples in future treatment costs.
    • Schools, employers, communities, and citizens must collectively embrace a preventive mindset, controlling risks, raising awareness, and fostering long-term health security.
    • Without this shift, India risks being overwhelmed by the growing burden of non-communicable diseases.
  • Digital Transformation and Technological Innovation

    • India was an early adopter of telemedicine and continues to advance digital health solutions.
    • Artificial Intelligence tools that detect early signs of illness, triage diagnostic reports, and enable remote consultations are already in use.
    • These innovations optimise medical resources and extend care to remote regions.
    • Moreover, digital health is democratising access. A cardiologist in a metropolitan city can now guide treatment for a rural patient hundreds of kilometers away.
    • Supported by the Ayushman Bharat Digital Mission, universal health records and continuity of care are increasingly within reach.

Regulation and Trust: The Missing Link

  • Innovation alone is insufficient without trust. Rising health-care costs, such as insurers considering premium hikes due to pollution-driven illnesses, highlight the urgent need for regulatory safeguards.
  • Robust oversight by the Insurance Regulatory and Development Authority of India (IRDAI) is essential for fair pricing, transparent claims settlement, and grievance redressal.
  • Without confidence in the system, households will remain reluctant to prioritise insurance.
  • In 2023, India’s health sector attracted $5.5 billion in private equity and venture capital, but this capital must be channelled into tier-2 and tier-3 cities to build primary networks and train specialists. Only then can growth translate into inclusion.

Conclusion

  • India’s health-care system is at an inflection point; Insurance must evolve to cover everyday care, providers must extend efficiency beyond urban centres, prevention must curb long-term costs, and technology must democratize access.
  • Regulation and investment must ensure trust and inclusion, while public-private partnerships can scale solutions sustainably.
  • The vision is clear: health care must shift from being a privilege to becoming a universal right.
  • If India can align policy, innovation, and participation, it will not only secure a healthier future for its citizens but also emerge as a global model for resilient and inclusive health care.

Building Health for 1.4 billion Indians FAQs

 Q1. Why is insurance considered the foundation of affordability in India’s health-care system?

Promotion and Regulation of Online Gaming Act, 2025 – Constitutional, Legal and Policy Debates

Context:

  • The Indian Parliament recently passed the Promotion and Regulation of Online Gaming Act, 2025, after minimal debate.
  • The Act bans online real-money games like rummy and poker while claiming to promote innovation and protect against socio-economic, public health, and privacy concerns.
  • The law raises constitutional, legal, and policy questions about the Union Government’s competence and proportionality of restrictions on individual liberty.

Key Features of the Act:

  • About the law: It ostensibly aims to promote online gaming and protect individuals with respect to social, economic and privacy-related concerns.
  • Objective: To secure a safe, innovation-friendly digital environment while addressing the public health, public morality and financial sovereignty risks of online gaming.
  • Provisions: To completely ban all online games involving real money, such as rummy and poker. Thus, the law retains “promotion” rhetoric but adopts a prohibitive approach.

Union vs State Powers:

  • Constitutional allocation: Following subjects primarily lies in the State domain as per Schedule VII List II (State List) of the Indian constitution -
    • Sports, entertainments, amusements
    • Betting and gambling
    • Public health, trade and commerce
  • Issue:
    • By regulating online gaming, the union government assumes legislative competence by citing public interest.
    • This raises federalism concerns since the subject lies in the State domain.

Government’s Rationale:

  • Addiction and mental health: Due to the temptation of these "predatory gaming platforms," Indian youth are rapidly spiralling into financial instability and mental health crises (WHO).
  • Cybersecurity and financial risks:
    • Unlike offline games, software coding in online games can manipulate odds against players.
    • Online games are vulnerable to fraud, money laundering, identity concealment.
  • Moral and social grounds: Online money gaming are seen as predatory platforms exploiting youth.

Critical Issues and Debates:

  • Liberty and proportionality:

    • Ban restricts adult autonomy in a free country.
    • Constitutional law demands that restrictions be rational, necessary, suitable, proportionate.
    • Current ban risks being seen as excessive and paternalistic.
  • Rational nexus question:

    • Does banning online real-money games actually prevent mental/financial crises?
    • Risk of underground, unregulated markets that are accessible through VPNs and dark web.
  • Policy alternatives:

    • Instead of outright ban, possible regulatory measures are -
      • Licensing of gaming companies.
      • Strict fiscal controls and limits on the stakes players choose to play for.
      • Age restrictions and player verification.
      • Taxation and monitoring for accountability.
  • Socio-economic considerations:

    • Need for mental health support systems.
    • Employment creation as an alternative to risky online earnings.

Unanswered Questions:

  • Why differentiate between online and offline real-money games?
  • Is prohibition more effective than strict regulation?
  • Does Union intervention violate the federal spirit of the Constitution?
  • How will enforcement tackle cross-border digital platforms?

Conclusion:

  • The future of online gaming regulation in India must move beyond prohibition towards a balanced framework of accountability, innovation, and player protection, ensuring that risks are addressed without undermining federalism or individual liberty.
  • A nuanced regulatory approach with licensing, safeguards, and mental health interventions can transform the sector into a source of responsible entertainment, economic growth, and digital innovation.

India’s Samudrayaan Mission: Human Deep-Sea Exploration by 2027

Samudrayaan Mission

Samudrayaan Mission Latest News

  • Two Indian aquanauts, Cdr (Retd) Jatinder Pal Singh and R Ramesh, undertook training dives aboard the French vessel Nautile, reaching depths of 5,002 and 4,025 metres in the Atlantic Ocean earlier this month. 
  • These preparatory missions are crucial for India’s ambitious Samudrayaan project, which aims to send three humans 6,000 metres deep into the ocean by 2027. 
  • The experience, much like how Axiom-4 supports Gaganyaan, will provide vital insights for advancing India’s deep-sea exploration capabilities.

Samudrayaan Mission: India’s Deep Ocean Exploration Plan

  • The Samudrayaan Mission, part of India’s Deep Ocean Mission approved in 2021 with an outlay of ₹4,077 crore over five years, aims to explore and sustainably utilise deep ocean resources. 
  • Its objectives include developing technologies for deep-sea mining, underwater vehicles, robotics, and a crewed submersible to carry three humans up to 6,000 metres below sea level. 
  • Other components involve creating: 
    • An ocean climate change advisory service, 
    • exploring and conserving deep-sea biodiversity, 
    • conducting surveys for mineral deposits, and 
    • innovating technologies for deriving energy and freshwater from the ocean. 
  • Additionally, the mission will establish an advanced marine station to boost research-to-industry applications in ocean biology and engineering, thereby supporting India’s blue economy.
  • The National Institute of Ocean Technology (NIOT) is the coordinating agency leading the development of the human-carrying submersible.

Matsya-6000: India’s Crewed Deep-Sea Submersible

  • Matsya-6000 is the specialised vehicle being developed under India’s Samudrayaan Mission to carry three aquanauts to a depth of 6,000 metres in the ocean. 
  • Shaped like a large fish, it houses a 2.1-metre diameter personal sphere designed to safely accommodate the crew. 
  • The submersible will support human life for 12-hour missions, with backup systems ensuring survival for up to 96 hours in emergencies
  • For the initial human trials at 500 metres depth, a steel sphere will be used, though this material cannot withstand the extreme pressures at 6,000 metres (around 600 times atmospheric pressure at sea level). 
  • For the full-scale mission planned for 2027, the personal sphere will be constructed from a titanium alloy with 80 mm thickness, offering the required strength and durability for deep-sea exploration.

Challenges of India’s Crewed Deep-Sea Mission under Samudrayaan

  • India’s Samudrayaan Mission, which aims to send three aquanauts to a depth of 6,000 metres, faces multiple scientific, engineering, and human challenges.

Developing a Pressure-Resistant Vessel

  • The foremost challenge is building a submersible strong enough to withstand extreme ocean pressure — nearly 600 times atmospheric pressure at 6,000 metres. 
  • A titanium alloy personal sphere (2.1 m diameter, 80 mm thick) is being developed by ISRO. 
  • The challenge lies in sourcing titanium (a rare and strategically controlled material) and achieving precise electron beam welding, as even a 0.2 mm deviation in thickness could cause catastrophic collapse.

Maintaining a Livable Environment

  • Inside the confined personal sphere, aquanauts will require a controlled atmosphere with 20% oxygen levels and regulated carbon dioxide scrubbing. 
  • Emergency backup systems include packed re-breather oxygen units that recycle exhaled air, similar to diving systems.

Ensuring Aquanaut Health and Safety

  • Aquanauts must be in peak physical condition to endure long hours under extreme pressure and respond effectively to emergencies. 
  • With no access to washrooms, food and water intake is minimised before and during the mission. 
    • For instance, during a nine-hour test dive to 5,002 metres, Cdr (Retd) Jatinder Pal Singh consumed only a few dry fruits.

Overcoming Communication Barriers

  • Radio waves cannot penetrate deep waters, making conventional communication impossible. 
  • Instead, India has developed its own acoustic telephone, which transmits sound waves to receivers near the surface. 
  • Early harbour tests failed due to factors like temperature and salinity, but the system later worked successfully in open sea trials.

India’s Push for Deep Sea Exploration under the Blue Economy Vision

  • India, with its 7,517 km-long coastline, is investing in deep-sea missions as part of its Blue Economy strategy to drive future growth and sustainable resource use. 
  • The deep ocean remains largely unexplored but holds vast reserves of minerals, fuels, and biodiversity, which can boost economic and scientific development.
  • Exploring under-explored domains like the deep sea and outer space will play a crucial role in achieving the government’s vision of “Viksit Bharat”. 
  • With the Samudrayaan Mission, India aims to send humans to 6,000 metres below sea level by 2027, placing it among the few nations — including the United States, Russia, China, Japan, and France — with advanced deep-sea exploration capability.

School Enrolment Declines Amid Falling Birth Rates & Demographic Shifts

School Enrolment

School Enrolment Latest News

  •  India’s school enrolment fell by 25 lakh in 2024-25, with UDISE+ data linking the decline to falling birth rates and rising preference for private schools.

Introduction

  • India’s school enrolment figures have witnessed a concerning decline for the third consecutive year. 
  • According to the latest Unified District Information System for Education Plus (UDISE+) data released by the Ministry of Education, total enrolment of students aged 3 to 11 dropped by nearly 25 lakh in 2024-25 compared to the previous year
  • Overall, total enrolment across Classes 1-12 fell by 11 lakh students, marking the lowest level since 2018-19. 
  • While falling birth rates are a primary reason, migration patterns, demographic transitions, and the expansion of private schools are shaping India’s changing education landscape.

Trends in School Enrolment

  • The UDISE+ 2023-24 report recorded 12.09 crore students in foundational and preparatory stages. 
  • This number declined to 11.84 crore in 2024-25, registering a dip of 24.93 lakh students. 
  • Similarly, total enrolment across schools (Classes 1-12) dropped from 24.80 crore in 2023-24 to 24.69 crore in 2024-25. This continuing decline marks a structural shift in India’s school-age population.
  • While government schools have seen steady reductions in enrollment, private schools have registered growth. 
    • Government school enrolment declined from 13.62 crore in 2022-23 to 12.16 crore in 2024-25, while private schools saw a rise from 8.42 crore to 9.59 crore over the same period. 
  • This reflects parents’ increasing preference for private institutions despite higher costs.

Causes Behind the Decline

  • Falling Birth Rates
    • A major driver of this enrollment dip is India’s declining fertility rate. The National Family Health Survey 2021 reported India’s Total Fertility Rate (TFR) at 1.91, below the replacement level of 2.1. 
    • Except for states like Uttar Pradesh, Bihar, and Meghalaya, most have fertility rates below replacement levels. 
    • With fewer children being born, the natural pipeline of primary school-age students has shrunk.
  • Data Accuracy and Methodology Changes
    • The enrollment decline since 2022-23 also coincides with a new methodology adopted by UDISE+, which now records individual student data rather than aggregated school-level numbers. 
    • This change weeded out duplicate entries, contributing to a more accurate, though lower, enrollment figure.
  • Migration and Private Sector Expansion
    • Migration to urban centres and the increasing prevalence of standalone private pre-primary institutions have influenced enrolment statistics. 
    • Many children are now being enrolled in private nurseries and preschools outside the government data system, further explaining the decline in official numbers.

Positive Indicators Amid Decline

  • Gross Enrolment Ratio (GER): GER at the middle school level improved from 89.5% in 2023-24 to 90.3% in 2024-25, and at the secondary level from 66.5% to 68.5%. This suggests that a higher proportion of eligible children are staying within the school system.
  • Reduced Dropout Rates: Dropout rates have consistently fallen. In preparatory stages, dropouts reduced from 3.7% in 2023-24 to 2.3% in 2024-25. Similarly, in secondary schools, dropout rates dropped from 10.9% to 8.2%.
  • Improved Gender Balance: While enrolment among boys slightly decreased, enrolment among girls remained stable and even saw marginal improvement.
  • Teacher-Student Ratios: Teacher availability has improved significantly. At the foundational level, the teacher-student ratio improved from 1:15 in 2014-15 to 1:10 in 2024-25, indicating better learning conditions.

Long-Term Implications

  • The consistent decline in enrolment reflects broader demographic transitions in India. 
  • As the country edges towards an ageing society, education policies will need to adapt to shrinking cohorts of young learners. 
  • This could allow for more investment per student, higher-quality learning environments, and a focus on improving learning outcomes rather than expanding enrolment.
  • At the same time, the rising preference for private schools underscores the need for policy reforms in government schooling. 
  • Strengthening infrastructure, ensuring accountability, and raising teaching standards will be crucial to retaining enrolment in public schools. 
  • Additionally, once Census 2026 data becomes available, the true extent of demographic changes and their implications for India’s education system will be clearer.
