  • Talent shortage — global challenge, India’s opportunity

    Why in the News?

    The demand for skilled workers will soon be higher than the supply, and India must act quickly to meet the needs of important regions.

    What are the Geographic regions and their demands?

    • Gulf Cooperation Council (GCC) – High Demand for Construction and Manufacturing: The GCC nations (e.g., UAE, Saudi Arabia, Qatar) require skilled construction and manufacturing workers to support infrastructure projects like NEOM (Saudi Arabia’s smart city project) and the Dubai Urban Plan 2040.
    • Europe (including the UK) – Service Sector Growth & Healthcare Needs: Europe, being the oldest post-industrial society, has a rising demand for healthcare professionals, IT experts, and service-sector workers due to ageing populations. Example: Germany’s “Skilled Immigration Act” aims to attract foreign talent in healthcare and technology.
    • Australia – Skilled Migration in Healthcare & Construction: Australia is open to skilled migration, especially in healthcare, IT, and construction due to labour shortages. Example: Australia’s Priority Migration Skilled Occupation List (PMSOL) focuses on attracting doctors, engineers, and tech professionals.
    • Global Demand in Emerging Sectors – AI, Big Data, and Automation: Countries worldwide, including the US, Canada, and Singapore, require expertise in Artificial Intelligence (AI),the  Internet of Things (IoT), blockchain, and big data analytics. Example: Singapore’s Tech. Pass visa encourages AI and IT experts to work in its digital economy.
    • Health and Social Care – Universal Demand: Aging populations in developed countries are driving high demand for nurses, caregivers, and medical professionals across the GCC, Europe, and Australia. Example: The UK’s Health and Care Worker visa prioritizes foreign healthcare workers to fill staffing gaps in the NHS.

    Why is the demand for skilled workers expected to exceed the supply in the near future?

    • Rapid Technological Advancements: Emerging technologies such as artificial intelligence (AI), machine learning, and cybersecurity are evolving swiftly, creating a need for specialized skills that the current workforce lacks. Example: The global AI market is projected to reach $266 billion by 2027, growing at a compound annual rate of 33.2%.
    • Industry-Specific Skill Gaps: Certain industries are experiencing rapid growth, leading to specialized skill shortages that the existing workforce cannot meet. Example: The International Renewable Energy Agency (IRENA) estimates that by 2030, the renewable energy sector could provide up to 30 million new jobs worldwide.
    • Aging Workforce and Retirements: A significant portion of the skilled workforce is approaching retirement age, leading to a loss of expertise and creating vacancies that are difficult to fill. Example: In the United States, the manufacturing sector faces a potential shortage of 2.1 million workers by 2030 due to retirements and a lack of new entrants with the necessary skills.
    • Mismatch Between Education and Industry Needs: Educational institutions often do not align curricula with the evolving demands of industries, resulting in graduates lacking the practical skills required by employers. Example: In India, a study by the National Skill Development Corporation (NSDC) revealed a demand for 103 million skilled workers, while the current supply is only 74 million.

    What are the existing barriers? 

    • Complex Visa Processes: Lengthy visa approval times and restrictive work permit policies hinder skilled worker migration. According to the Global Talent Competitiveness Index (2023), India ranks 92nd in the ability to enable and attract global talent, reflecting challenges in cross-border workforce movement.
    • Exploitation of Migrant Workers: Illegal recruitment agencies engage in wage theft and exploitative practices. As per the International Labour Organization (ILO), approximately 25 million people worldwide are victims of forced labour, with South Asia being a major source of trafficked labour.
    • Non-Recognition of Qualifications: Many Indian professional degrees are not accepted in key global markets. A FICCI-KPMG study reports that 53% of Indian professionals face underemployment abroad due to non-recognition of their qualifications, particularly in medicine and engineering.
    • Limited Language Proficiency: Inability to communicate effectively impacts job performance and integration. The European Commission (2022) found that 40% of non-EU migrants face employment challenges due to language barriers, particularly in sectors like healthcare and customer service.
    • Mismatch Between Skills and Market Needs: Rapid technological advancements outpace current training programs. According to the World Economic Forum (WEF) Future of Jobs Report (2023), 44% of core skills required across industries will change by 2027, leaving a global shortfall of 85.2 million skilled workers by 2030.

    What are the existing strategies? 

    • Migration and Mobility Partnerships: India has established agreements with countries like Germany and Italy to facilitate the movement of students, professionals, and skilled workers. These partnerships aim to streamline visa processes and recognize professional qualifications, thereby promoting bilateral exchanges.
    • Digital Platforms for Emigrant Support: The Indian government has upgraded the eMigrate portal to version 2.0, integrating features like 24/7 multilingual helpline support and faster feedback mechanisms. This platform ensures transparency in recruitment and safeguards the welfare of Indian workers abroad.
    • Skill Development Initiatives: Through programs like the National Skill Development Mission and the Skill India program, India focuses on training its workforce in emerging technologies and sectors. These initiatives aim to align domestic skills with global market demands, enhancing employability abroad.
    • International Collaboration on Education and Training: Workshops and collaborative projects with entities like the European Union have been conducted to strengthen student mobility and the use of educational consultants. These efforts aim to facilitate the international movement of students and young professionals.
    • Bilateral Trade Agreements Enhancing Labor Mobility: India is actively pursuing free trade agreements, such as the one with the United Kingdom, which include provisions for labour mobility. These agreements aim to reduce barriers for Indian professionals seeking opportunities abroad.

    What is India’s advantage?

    • Large and Growing Workforce: India has one of the world’s largest working-age populations, providing a steady supply of skilled workers. Example: By 2030, India’s working-age population is expected to reach 1.04 billion, accounting for 23% of the global workforce (UN Population Report, 2022).
    • Cost-Effective Skilled Labour: Indian workers offer high skill levels at competitive costs, making them attractive to global markets. Example: Indian IT professionals earn 60-70% less than their Western counterparts, enabling global firms to save on operational costs (NASSCOM, 2023).
    • Strong Diaspora and Global Networks: India has the second-largest diaspora globally, facilitating knowledge transfer and job opportunities. Example: Over 4.2 million Indian-origin people live in the United States, contributing significantly to sectors like technology and healthcare (US Census Bureau, 2022).
    • Government-Led Skill and Mobility Initiatives: India has established programs to train and mobilize workers for global opportunities. Example: The Skill India Mission has trained over 40 million workers since 2015, aligning their skills with global market demands (Ministry of Skill Development, 2023).
    • Favourable Global Perception: Indian workers are perceived as hardworking and adaptable, maintaining demand despite anti-immigration trends. Example: 25% of doctors in the UK’s NHS are of Indian origin, reflecting their sustained demand and acceptance (UK General Medical Council, 2023).

    Way forward: 

    • Strengthen Skill Recognition and Mutual Agreements: Expand bilateral agreements for mutual recognition of qualifications to reduce skill mismatch and underemployment, especially in high-demand sectors like healthcare and technology.
    • Enhance Digital and Legal Safeguards for Migrant Workers: Improve digital platforms like eMigrate for transparent recruitment, and enforce stricter regulations against exploitative practices to protect Indian workers abroad.

  • [21st February 2025] The Hindu Op-ed: Is consumption enough to drive growth?

    PYQ Relevance:

    Q) Explain the difference between the computing methodology of India’s Gross Domestic Product (GDP) before the year 2015 and after the year 2015. (UPSC CSE 2021)

     

    Mentor’s Comment: UPSC mains have always focused on India’s Gross Domestic Product  (2021), and India from realizing its potential GDP (2020).

    An economy grows through two key factors: supply (production of goods and services) and demand (spending on these goods and services). Among demand sources, investment is crucial as it creates a multiplier effect, boosting jobs and income. Consumption follows growth but cannot drive it alone, as sustainable expansion requires strong investment and production.

    Today’s editorial talks about India’s GDP growth factors based on demand and supply. This content would help in GS Paper 3 mains Paper.

    _

    Let’s learn!

    Why in the News?

    An economy’s growth is like navigating two interconnected boats—one representing the supply or production of goods and services.

    Is consumption enough to drive growth?

    Consumption plays a crucial role in driving economic growth, but it is not sufficient on its own for sustainable long-term growth.

    • Consumption-Led Growth is Slower: While consumption boosts demand, it does not create long-term productive capacity. Example: India’s GDP growth in recent years has been driven by consumption (60.3% of GDP in 2023), but it lags behind China’s investment-driven growth.
    • Limited Multiplier Effect: Unlike investment, increased consumption has a weaker impact on overall income and job creation. Example: If people buy more smartphones, it benefits retailers but does not significantly boost domestic production if phones are imported.
    • Investment is Crucial for Sustainable Growth: Higher investment in infrastructure, industries, and technology leads to job creation and productivity gains. Example: China’s high investment rate (41.3% of GDP in 2023) has helped it achieve rapid economic growth and higher per capita income than India.

    Why is economic growth dependent on two factors?

    • Balanced Growth Requires Both Supply & Demand: Economic growth happens when goods and services are produced (supply) and purchased (demand) in a balanced manner.
      • Example: A country increasing factory production (supply) must also have enough consumers to buy the products (demand), ensuring sustainable growth.
    • Mismatch Leads to Economic Problems
      • If demand > supply, inflation rises due to excessive spending with limited goods.
      • If supply > demand, businesses suffer from unsold stock, leading to job losses.
      • Example: Post-pandemic, supply chain disruptions led to high demand but low supply, causing inflation.
    • Investment Drives Long-Term Growth: Investment in infrastructure, industries, and technology increases production capacity (supply) while also creating jobs, which boosts spending power (demand).
      • Example: China’s high investment in infrastructure and manufacturing led to rapid economic growth by expanding both supply and demand.
    • Government Policies Impact Both Sides: Fiscal and monetary policies help balance supply-side growth (e.g., industrial incentives) and demand-side expansion (e.g., tax cuts or subsidies).
      • Example: India’s Production-Linked Incentive (PLI) scheme boosts manufacturing (supply), while government social schemes increase purchasing power (demand).
    • Exports and Imports Affect Domestic Growth: A strong export sector increases supply, bringing foreign exchange, while controlled imports ensure domestic industries remain competitive.
      • Example: India’s IT exports generate revenue (supply), while consumer imports like electronics influence domestic demand.

    What role does investment play in economic growth?

    • Boosts Production Capacity: Investment in factories, infrastructure, and technology increases the ability to produce goods and services, leading to higher GDP. Example: China’s heavy investment in manufacturing and infrastructure helped it become the world’s largest exporter.
    • Creates Employment Opportunities: New industries and infrastructure projects generate jobs, increasing income and overall demand in the economy. Example: India’s road and metro projects have created millions of direct and indirect jobs, boosting economic activity.
    • Multiplier Effect on Demand & GDP: Investment leads to increased income, which in turn increases consumption and demand, further driving growth. Example: A ₹100 investment in building highways can create ₹125 in overall economic output due to increased business activities along the route.
    • Encourages Private Sector Confidence: When the government invests in key sectors, it builds confidence among private businesses to invest further. Example: India’s Production-Linked Incentive (PLI) scheme for electronics manufacturing has attracted global tech firms to set up production units.
    • Leads to Technological and Industrial Development: Investments in research, innovation, and new industries enhance productivity and global competitiveness. Example: South Korea’s investment in R&D and technology made it a leader in electronics and automobile industries.

    How have India and China experienced changes in per capita income?

    • Similar Per Capita Incomes in the Early 1990s: In the early 1990s, India and China had nearly equal per capita incomes, with both countries being 1.5% of the U.S. average. Example: In 1992, both nations were considered low-income economies with similar economic structures.
    • China’s Investment-Led Growth Model: China prioritized high investment rates, focusing on infrastructure, state-owned enterprises, and manufacturing. Example: In 1992, China’s investment rate was 39.1% of GDP, much higher than India’s 27.4%.
    • Diverging Growth Post-2000s: India’s investment rate rose to 35.8% in 2007, almost matching China’s, but declined after 2012 due to policy uncertainty and global economic slowdown.Example: By 2013, China’s investment rate increased to 44.5%, while India’s fell to 31.3%.
    • China’s Faster Rise in Per Capita Income: By 2023, China’s per capita income was 5 times India’s in nominal terms and 2.4 times higher in purchasing power parity (PPP). Example: As a percentage of U.S. per capita income in 2023: China: 15%, India: 3%.
    • India’s Consumption-Driven Growth Model: India’s economic growth has been mainly driven by domestic consumption, while China maintained higher investment levels. Example: In 2023, consumption was 60.3% of India’s GDP, compared to 39.1% in China.
    • Long-Term Impact on Growth and Inequality: India’s lower investment and trade deficits have led to slower per capita income growth, affecting job creation and economic equality. Example: China’s investment rate in 2023 was 41.3%, whereas India’s was only 30.8%, limiting economic expansion.

    What measures has the Indian government taken to promote investment in India?

    • Infrastructure Development: The government has launched massive infrastructure projects to boost investment and improve connectivity. Example: PM Gati Shakti (National Master Plan) aims to integrate multi-modal transport networks and reduce logistics costs.
    • Production-Linked Incentive (PLI) Scheme: Introduced to boost manufacturing and attract foreign and domestic investments in key sectors. Example: PLI schemes for electronics, pharmaceuticals, and renewable energy have encouraged global firms to set up production in India.
    • Corporate Tax Reforms: India reduced corporate tax rates to make the investment climate more competitive. Example: In 2019, the corporate tax rate was slashed to 22% for existing companies and 15% for new manufacturing firms.
    • Ease of Doing Business & FDI Reforms: Simplified regulatory processes, digital approvals, and single-window clearances to attract investments. Example: 100% FDI allowed in sectors like defense, telecom, and insurance under automatic route.

    Way forward: 

    • Enhancing Investment-Led Growth: India should focus on increasing capital formation by boosting infrastructure, industrial productivity, and R&D investments. Strengthening public-private partnerships (PPPs) and expanding the PLI scheme to emerging sectors can accelerate long-term economic growth.
    • Balancing Consumption and Supply-Side Expansion: While consumption remains a key driver, policies should encourage domestic manufacturing and export competitiveness to reduce reliance on imports. Strengthening skill development and labour market reforms will enhance productivity and job creation.

  • On building resilient telecom infrastructure

    Why in the News?

    The Coalition for Disaster Resilient Infrastructure (CDRI), a global organization launched by Prime Minister Narendra Modi in 2019, recently released a report assessing how well Indian telecom networks can handle disasters.

    What does the Coalition for Disaster Resilient Infrastructure report state?

    • Multi-Hazard Risk Assessment: The report conducted a comprehensive risk assessment across 0.77 million telecom towers, evaluating vulnerabilities to various disasters such as floods, cyclones, and earthquakes, which informs infrastructure planning and resilience strategies.
    • Disaster Risk and Resilience Index: A new index was developed to assess the vulnerability of telecom infrastructure based on factors like disaster intensity and frequency, enabling targeted risk management efforts.
    • Technical and Governance Enhancements: Recommendations include improving technical planning and design of telecom infrastructure to withstand disasters, as well as integrating disaster resilience into sectoral policies through risk-informed governance.
    • Financial Instruments and Collaboration: The report advocates for establishing risk-sharing mechanisms to protect telecom operators financially, alongside promoting cross-sectoral collaboration for coordinated disaster response efforts.
    • Last-Mile Connectivity and Digital Solutions: Emphasizing the importance of inclusive emergency responses, the report calls for enhancing last-mile connectivity and leveraging digital solutions to ensure rapid service restoration during crises.

    Why do telecom networks face elevated risks in coastal regions in times of disaster and calamity?

    • High Exposure to Cyclones & Storm Surges: Coastal areas frequently experience high-speed winds and storm surges, which can damage telecom towers and disrupt communication. Example: During Cyclone Amphan (2020), telecom networks in West Bengal and Odisha were severely impacted due to tower collapses and flooding.
    • Vulnerability of Undersea Cable Landing Stations: Undersea cables connect India to global internet infrastructure, and their landing stations are located in coastal regions. Damage to these stations can cause widespread internet outages. Example: In 2023, a disruption in undersea cables near the Red Sea affected internet speeds in South Asia, including India.
    • Power Failures Due to Flooding & Infrastructure Damage: Coastal disasters often lead to massive power outages, affecting telecom towers and network operating centres that rely on continuous electricity. Example: During Cyclone Tauktae (2021), heavy rainfall and flooding in Mumbai led to prolonged telecom disruptions due to power cuts and submerged backup generators.

    Why are undersea cables better than overland cables?

    • Higher Capacity: Undersea cables can carry vast amounts of data, with total capacities reaching terabits per second, significantly surpassing the capabilities of satellite communications, which typically offer much lower bandwidth (around 1 gigabit per second).
    • Lower Latency: The signal transmission time is considerably shorter with undersea cables than with satellite links. For example, latency over a fibre submarine cable is around 120 milliseconds, while satellite communications can introduce delays of approximately 650 milliseconds due to the long distances signals must travel to and from space.
    • Cost-Effectiveness: Laying undersea cables is generally more economical than deploying satellite systems for large-scale data transmission. The initial investment in submarine cables, while significant, is offset by their capacity and reliability, making them a more sustainable option for long-term infrastructure.
    • Reliability and Stability: Undersea cables are less susceptible to environmental factors that can disrupt overland cables, such as weather conditions or physical damage from construction activities. Their placement on the seabed provides a level of protection against many potential hazards.
    • Global Connectivity: Submarine cables are essential for connecting continents and regions that are separated by water. They facilitate international data traffic and play a critical role in global communications, making them indispensable for the functioning of the Internet and other communication networks.

    Does power failure create major problems?

    • Disrupts Communication During Emergencies: Telecom towers and network operating centres require continuous power to function. When electricity is cut off, mobile networks and internet services fail, hindering disaster response.
      • Example: During Cyclone Fani (2019), Odisha experienced massive power outages, causing mobile networks to shut down, and delaying rescue operations.
    • Limits Functionality of Backup Systems: Most telecom towers rely on battery or diesel generators, but these backups last only a few hours. If the fuel supply is disrupted, networks remain down for extended periods.
      • Example: In the Assam floods (2022), fuel shortages prevented telecom towers from running generators, prolonging communication blackouts.
    • Affects Undersea & Land-based Network Infrastructure: Power failures at undersea cable landing stations and data centres can cause large-scale internet outages, affecting national and global connectivity.
      • Example: A power failure at a Chennai cable landing station in 2021 disrupted international internet traffic.

    Way forward: 

    • Strengthening Resilient Power Solutions: Deploy renewable energy sources like solar-powered telecom towers and battery storage systems to ensure uninterrupted network operations during disasters.
    • Enhancing Risk-Informed Governance: Integrate disaster resilience planning into telecom policies, mandate robust backup power solutions, and establish coordinated emergency response frameworks for rapid service restoration.

  • Why global sea ice cover has dipped to record low — what this means

    Why in the News?

    Between February 8 and 13, the total area of sea ice in the Arctic and Antarctic shrank to 15.76 million sq km, breaking the previous record low of 15.93 million sq km from early 2023, according to a BBC analysis of data from the US National Snow and Ice Data Center (NSIDC).

    What are the reasons for the record low?

    • Warm Air and Ocean Temperatures: Elevated air and sea temperatures have significantly contributed to the melting of both Arctic and Antarctic sea ice. Warmer conditions, particularly towards the end of summer, have led to increased melting rates, especially in the Antarctic region.
    • Wind Patterns: Changes in atmospheric dynamics, including stronger westerly winds associated with the Southern Annular Mode (SAM), have disrupted sea ice formation and stability. In the Antarctic, these winds can break apart ice more easily due to its thinner and more mobile nature compared to the thicker Arctic ice.
    • Delayed Freezing: In the Arctic, a delayed freezing process around regions like Hudson Bay has occurred due to unusually warm ocean temperatures, preventing the formation of new ice during winter.
    • Increased Freshwater Input: The melting of glaciers and ice shelves adds freshwater to the oceans, which can alter ocean stratification and impact sea ice formation. While freshwater can initially encourage sea ice growth in some contexts, it also leads to changes that may ultimately reduce overall sea ice extent.
    • Feedback Mechanisms: The loss of sea ice creates feedback loops that further exacerbate warming. As less ice remains to reflect sunlight, more solar radiation is absorbed by the ocean, leading to increased temperatures and further melting of ice.

    What does “dip” mean?

    • In the context of the recent report on sea ice, the term “dip” refers to a significant decrease or reduction in the extent of sea ice coverage. Specifically, it denotes the record low measurement of combined Arctic and Antarctic sea ice, which fell to 15.76 million square kilometres, marking a decline from previous levels.
    • This “dip” highlights the alarming trend of diminishing sea ice, which is crucial for regulating global temperatures and maintaining ecological balance in polar regions.

    What could be its impact?

    • Accelerated Global Warming: Less sea ice means more ocean water is exposed to sunlight, absorbing heat instead of reflecting it. Example: The Arctic is warming nearly four times faster than the global average, leading to extreme weather patterns worldwide.
    • Disruptions in Ocean Currents: Melting sea ice releases freshwater into the ocean, reducing salinity and slowing down deep-water circulation. Example: The Atlantic Meridional Overturning Circulation (AMOC), which influences global climate patterns, is weakening due to increased freshwater from melting Arctic ice.
    • Threat to Marine Ecosystems: Sea ice loss affects marine species dependent on stable ice conditions for survival. Example: Polar bears rely on sea ice for hunting seals. As ice declines, they face starvation and habitat loss. Similarly, krill populations in Antarctica, a key food source for whales and penguins, are declining due to changing ice conditions.
    • More Extreme Weather Events: Changes in polar ice influence atmospheric circulation, leading to unpredictable weather. Example: The weakening of the polar vortex due to Arctic warming has been linked to severe cold waves in North America and Europe, such as the Texas winter storm in 2021.
    • Coastal and Infrastructure Damage: Rising temperatures due to ice melt contribute to permafrost thawing, which destabilizes infrastructure in polar regions. Example: In Siberia, Russia, thawing permafrost has caused buildings and roads to collapse, posing a major economic and environmental challenge.

    What measures have been taken at the international level?

    • International Year of Glaciers’ Preservation (2025): The World Meteorological Organization (WMO) and UNESCO have declared 2025 as the International Year of Glaciers’ Preservation. This initiative aims to raise awareness about the importance of glaciers and ice sheets, which store a significant portion of the world’s freshwater, and to promote actions to mitigate their melting.
    • Global Cryosphere Watch: The WMO’s Global Cryosphere Watch network, which includes scientists from the Intergovernmental Panel on Climate Change (IPCC), has been actively monitoring and reporting on cryosphere changes. Their findings highlight alarming trends in ice loss and emphasize the need for immediate action to address these issues.
    • Collaborative Research Initiatives: Various international scientific collaborations are underway to study and model the impacts of climate change on sea ice. These efforts involve researchers from multiple countries working together to gather data, analyze trends, and develop strategies for adaptation and mitigation.
    • Climate Action Frameworks: Global climate agreements, such as the Paris Agreement, encourage countries to commit to reducing greenhouse gas emissions, which are a primary driver of climate change affecting sea ice.
    • Public Awareness Campaigns: International organizations are engaging in campaigns to educate the public about the significance of sea ice and glaciers in regulating global climate systems.

    Way forward: 

    • Strengthening Climate Mitigation Efforts: Nations must enhance commitments under the Paris Agreement by accelerating renewable energy adoption, reducing greenhouse gas emissions, and implementing carbon pricing mechanisms to curb global warming.
    • Enhancing Polar and Oceanic Monitoring: Strengthen international collaboration for real-time satellite monitoring, expand scientific research on polar ice dynamics, and develop adaptive strategies to protect vulnerable ecosystems and coastal communities.

    About Periodic Labour Force Survey (PLFS)

    • The PLFS is conducted by the National Statistical Office (NSO), Ministry of Statistics and Programme Implementation (MoSPI) to assess employment and unemployment trends in India.
    • Launched in April 2017, PLFS provides quarterly estimates for urban areas and annual estimates for both rural and urban areas.
    • Key Indicators:
    1. Labour Force Participation Rate (LFPR): Percentage of people working or seeking jobs.
    2. Worker Population Ratio (WPR): Percentage of people employed.
    3. Unemployment Rate (UR): Percentage of job seekers unable to find employment.
    4. Current Weekly Status (CWS): Employment status based on work done in the last 7 days.
    • Survey Methodology:
      • Urban Areas: Rotational Panel Sampling (each household surveyed four times).
      • Data Collected (Oct-Dec 2024): 5,742 urban units surveyed, covering 1,70,487 individuals across 45,074 households.
      • Publication: Quarterly Bulletins for urban areas, Annual Reports for rural and urban regions.

    Key Highlights of PLFS (Oct-Dec 2024)

    • Labour Force Participation Rate (LFPR): 50.4% (↑ from 49.9% in 2023).
      • Male LFPR: 75.4% (↑ from 74.1% in 2023).
      • Female LFPR: 25.2% (↑ from 25.0% in 2023).
    • Worker Population Ratio (WPR): 47.2% (↑ from 46.6% in 2023).
      • Male WPR: 70.9% (↑ from 69.8% in 2023).
      • Female WPR: 23.2% (↑ from 22.9% in 2023).
    • Unemployment Rate (UR): 6.4% (↓ from 6.5% in 2023).
      • Male UR: 5.8% (unchanged).
      • Female UR: 8.1% (↓ from 8.6% in 2023).

    (d) productivity of workers is low

     

  • New study challenges the age of Saturn’s Rings

    Why in the News?

    A new study has challenged previous assumptions, suggesting that Saturn’s rings could be as old as the Solar System (~4.5 billion years old).

    New study challenges the age of Saturn’s Rings

    About Saturn and Its Rings

    • Saturn, the sixth planet from the Sun, is famous for its iconic ring system, made up of billions of ice and rock particles ranging in size from tiny grains to massive chunks.
    • It is primarily composed of water ice (95%), with some dust and rocky debris.
    • The rings are divided into seven main sections (A to G), with gaps like the Cassini Division.
    • Scientists have debated whether the rings formed with Saturn (~4.5 billion years ago) or if they are only 100-400 million years old.
    • Over time, tiny space rocks should darken the rings, yet they remain surprisingly bright.

    Key Findings of the Study:

    • Earlier estimates, based on Cassini data, suggested the rings were 100-400 million years old because they looked clean and bright.
    • The new study suggests that micrometeoroid collisions remove dust efficiently, preventing the rings from darkening over time.
    • High-speed micrometeoroid impacts (~108,000 km/h) cause dust to vaporize, rather than accumulate.
    • The vaporized dust either escapes Saturn’s gravity, falls into the planet’s atmosphere, or gets ejected into space, keeping the rings pristine.
    • 100 million years ago, the Solar System was stable, making ring formation unlikely.
    • 4 billion years ago, the Solar System was chaotic, increasing the chances of violent planetary collisions that could have formed Saturn’s rings.
