  • Can blood tests for cancer save more lives? 

    Why in the News?

    A multi-cancer early detection test can identify circulating tumour DNA or circulating tumour cells at an early stage, allowing for more effective treatment.

    Status of Cancer:

    • Cancer’s Impact in India: Cancer accounts for 18% of deaths from noncommunicable diseases in India, making it the second leading cause of mortality. In 2022, there were approximately 1.46 million new cancer cases, with projections indicating a 12% increase by 2025.
    • Common Cancers as per GLOBOCAN: Among women, the most prevalent cancers are breast, cervical, ovarian, and colorectal.
      • For men, lung, esophageal, colorectal, and stomach cancers are the most common.
    • Survival Rates and Detection: Late detection of cancer significantly reduces survival rates and increases treatment costs. In contrast, early detection through screening improves treatment outcomes and quality of life. 
      • Countries are aligning with the United Nations’ Sustainable Development Goals 3 to enhance early cancer detection.
    • Limited screening: As per NHFS, screening is limited in India which is primarily to cervical, breast, and oral cancers, with only 0.2-2% of the population having undergone any form of screening.

    What is a Multi-Cancer Early Detection (MCED) Test?

    • A multi-cancer early detection (MCED) test is a new type of blood test that can screen for multiple types of cancer simultaneously. These tests look for cancer signals, such as circulating tumor DNA (ctDNA) and circulating tumor cells (CTCs), released by cancerous cells into the bloodstream at early stages.

    Role of Blood-based tests in the detection of cancer:

    • Early Detection of Multiple Cancer Types: Blood tests, particularly multi-cancer early detection (MCED) tests, can identify cancer signals from over 50 different types of cancer, including those that currently lack effective screening methods.
      • For example, a recent study demonstrated that a new blood test could detect 93% of stage 1 cancers in men and 84% in women by analyzing protein biomarkers.
    • Non-Invasive and Accessible Screening: Blood tests are non-invasive and can be performed with a simple blood draw, making them more accessible compared to traditional screening methods like colonoscopies or imaging tests. This ease of use encourages more individuals to participate in screening.

    Limitation of blood test in the detection of Cancer:

    • Lack of Proven Mortality Benefit: It is still unclear whether detecting cancers earlier with MCED tests will actually reduce cancer deaths. More research is needed to determine if earlier treatment based on MCED results improves outcomes compared to waiting for symptoms to develop.
    • Regulatory Challenges: MCED tests are not yet approved by regulatory bodies like the U.S. FDA or India’s CDSCO because of not undergone rigorous premarket review to prove they benefit patients.
    • False Positives: One significant risk is false positive results, where the test indicates cancer when none is present. When multiple tests are used for screening, the false positive rate can be as high as 50%.

    Way forward:

    • Strengthening Screening Infrastructure and Research: India should invest in expanding its cancer screening infrastructure, ensuring that more types of cancer are included beyond cervical, breast, and oral cancers.
    • Public Awareness and Regulatory Preparedness: Increasing public awareness about the importance of early cancer detection is crucial. At the same time, regulatory bodies like CDSCO should establish clear guidelines and frameworks for the evaluation, approval, and monitoring of MCED tests.

  • What is Quantum Non-Locality?

    Why in the News?

    A recent study published in Physical Review Letters by Indian researchers has revealed that a universal standard for measuring quantum non-locality is impossible.

    What is Quantum Nonlocality?

    • Quantum Nonlocality is a mysterious connection between distant objects that challenges the classical idea of local realism, where no faster-than-light communication is allowed.
    • It’s crucial for technologies like secure communication, random number generation, and cryptographic key creation.
    • Easy Explanation:
      • Imagine two particles that are created together and then move far apart, even to opposite ends of the universe.
      • In classical physics, any effect on one particle would need a signal to travel to the other, taking time.
      • But in quantum physics, Quantum Nonlocality means these particles are instantly connected, affecting each other no matter the distance, as if linked by an invisible thread that works faster than light.

    Historical Background: Bell’s Theorem (1964)

    • Physicist John Stewart Bell introduced a theorem that challenged the classical idea of ‘local realism’ in quantum systems.
      • Local Realism: In classical physics, objects are believed to have definite properties independent of observation and are only influenced by their immediate surroundings.
      • Quantum Challenge: Bell demonstrated that in quantum systems with multiple, distant parts, correlations appear that cannot be explained by local realism.
    • Bell’s theorem was confirmed through experiments, leading to the recognition of quantum nonlocality, which was honored with the 2022 Physics Nobel Prize.

    Recent Research and Findings

    • The research demonstrates that a universal standard for measuring and comparing quantum nonlocality is impossible.
      • It shows that the nature of nonlocality varies based on the type of correlation, with infinite unique points on the correlation boundary.
      • There is no single, universal resource in the realm of quantum nonlocality; instead, each nonlocal resource is unique, capable of performing specific tasks that others cannot.
    • This observation plays a key role in secure communication, random number certification, and cryptographic key generation.

  • What is the Hayflick Limit?

    Why in the News?

    Leonard Hayflick, the renowned biomedical researcher who made a discovery about the limits of cell division in somatic cells (Hayflick Limit) has passed away at 98.

    What is the Hayflick Limit?

    • In the early 1960s, Hayflick discovered that somatic (non-reproductive) cells have a finite number of divisions, typically between 40-60 times.
    • This phenomenon, the ‘Hayflick limit’ suggests that aging occurs because cells eventually stop dividing.
      • This leads to the accumulation of senescent cells that contribute to the aging process.
    • The “ultimate Hayflick limit” for humans is estimated to be around 125 years.
    • Beyond this, no amount of lifestyle changes or medical interventions can extend the human lifespan.
    • Hayflick’s discovery has been applied to cells from various animals, revealing different Hayflick limits based on species’ lifespans.
    • Ex. Galapagos turtles, have cells that can divide approximately 110 times, whereas laboratory mice have a much lower limit of around 15 divisions.

    Broader Implications and Research

    • Hayflick’s discovery led to the discovery of telomeres in the 1970s.
      • Telomeres are protective DNA sequences at the ends of chromosomes, which shorten with each cell division.
    • When telomeres reach a critical length, cell division stops, which correlates with the Hayflick limit.
    • In the 1980s, scientists discovered telomerase, a protein capable of replenishing telomeres, which is naturally active in cancer cells, allowing them to bypass the Hayflick limit.

    PYQ Relevance:
    Mains:
    Q.1 Bring out the constructive programmes of Mahatma Gandhi during the Non-Cooperation Movement and Civil Disobedience Movement. (UPSC IAS/2021) 
    Q.2 Can the strategy of regional-resource-based manufacturing help in promoting employment in India? (UPSC IAS/2019) 

    Note4Students: 

    Prelims: Khadi and Village Industries Commission (KVIC);

    Mains: Challenges related to khadi industry;

    Mentor comments:  The khadi industry in India is a vital segment of the textile sector, known for its hand-spun and hand-woven fabrics made from cotton, silk, and wool. It plays a crucial role in generating employment, particularly in rural areas, with millions of artisans involved in its production. The industry has seen significant growth, with khadi production valued at ₹1,904.5 crore (USD 255.8 million) in FY21, up from ₹1,520.8 crore (USD 204.3 million) in FY17. Promoted by the Khadi and Village Industries Commission (KVIC), khadi symbolizes India’s heritage and commitment to sustainable practices.

    Let’s learn —

    Why in the News? 

    • The Prime Minister’s ‘Har Ghar Tiranga’ campaign highlights moral contradiction, as machine-made polyester flags, often imported, overshadow the significance of our national flag.
    • The Flag Code of India has historically required the national flag to be made of “hand spun and hand-woven wool/cotton/silk khadi bunting”

    Significance of Khadi Industries: 

    • Second Largest Employer: After agriculture, the khadi industry is the second largest industry to provide employment opportunities to the unemployed and rural people
    • Preserving Heritage: Khadi is a national heritage fabric of India with a unique identity and a rich tradition dating back to ancient times.
    • Symbol of Freedom Struggle: Khadi was the fabric of the freedom struggle, with Mahatma Gandhi launching the movement of ‘spin your own cloth and buy hand-spun cloth’ in 1921
    • Eco-friendly Production: The production of khadi focuses on the environment right from the beginning, using locally manufactured raw materials without chemicals and energy resources.

    The reason behind the Khadi procurement has fallen: 

    • Neglect of Mandates: Government departments are reportedly ignoring or overruling mandates requiring them to procure khadi. For instance, many departments shifted to other materials, resulting in a drop in khadi purchases from ₹50-60 crore per year to ₹32 crore over a decade.
    • Amendment to the Flag Code: In 2022, the Government amended the Flag Code of India to allow for the use of machine-made polyester bunting for the national flag, which historically required khadi.  
    • Tax Exemption for Polyester Flags: The government exempted polyester flags from the Goods and Services Tax (GST), placing them on the same tax footing as khadi flags.  
    • Indefinite Strike by Khadi Producers: The Karnataka Khadi Gramodyoga Samyukta Sangha (KKGSS), the sole national flag manufacturing unit accredited by the Bureau of Indian Standards, resorted to an indefinite strike to protest the government’s actions, which they view as detrimental to the khadi industry.
    • Market Regulation Failures: The khadi market lacks effective regulation, leading to the sale of khadi produced from semi-mechanized charkhas alongside traditional hand-spun khadi. This situation creates confusion among consumers and undermines the authenticity of traditional khadi.  
    • Lack of Global Promotion: The government has failed to establish a global audience for Indian handlooms, particularly khadi. For instance, khadi’s share remains very low, accounting for less than 0.22% of the total textile sector exports.  
    • Economic Pressures on Workers: Khadi spinners and weavers are facing economic hardships, with wages remaining low at ₹200-₹250 per day despite their labour-intensive work.  
    • Impact of Policy Changes: Recent policy changes, such as the introduction of the Goods and Services Tax (GST), have placed additional burdens on handloom workers. The GST applies to both finished khadi products and raw materials, increasing costs for producers.  
    Khadi and Village Industries Commission (KVIC)

    Establishment: The KVIC was established in April 1957 by the Government of India under the Khadi and Village Industries Commission Act. It is a statutory body aimed at promoting and regulating the khadi and village industries in India.
    Objectives: The KVIC has three main objectives:
    1. Social Objective: To provide employment in rural areas.
    Economic Objective: To produce saleable articles.
    2. Wider Objective: To create self-reliance among people and build a strong rural community spirit.

    Affiliation and Oversight: The KVIC oversees approximately 5,600 registered khadi institutions and 30,138 cooperative societies across India. It collaborates with 30 State Khadi and Village Industry Boards (KVIBs) to implement its programs at the state level.

    Trademark Protection: KVIC holds exclusive rights to the “Khadi” and “Khadi India” trademarks, ensuring that the term is used correctly and protecting the integrity of khadi products in the market.

    Way forward: 

    • Revitalize Government Mandates & Incentivize Khadi Procurement: Reinforce mandates requiring government departments to prioritize khadi procurement and introduce subsidies or tax incentives for using traditional hand-spun khadi, ensuring fair competition against synthetic alternatives.
    • Global Promotion & Fair Wages: Launch targeted campaigns to promote khadi internationally, increasing its market share while ensuring that khadi spinners and weavers receive fair wages through direct government support and better pricing mechanisms.
  • The path to Viksit Bharat runs through fields  

    Why in the News?

    India’s 78th Independence Day is a time to reflect on our significant successes and setbacks. We should learn from both to make quicker progress towards the Prime Minister’s vision of a Viksit Bharat@2047 by 2047.

    Key Aspects of Viksit Bharat@2047

    • Economic Growth: The vision aims to elevate India to the status of the world’s third-largest economy and strive for a $30 trillion economy by 2047.
    • Environmental Sustainability: Viksit Bharat aims to preserve biodiversity and mitigate climate change impacts through restoration and conservation efforts.
    • Social Progress: The initiative seeks to build an inclusive society that respects cultural diversity and ensures the dignity and well-being of all citizens.
    • Good Governance: Effective governance is a cornerstone of the Viksit Bharat vision, focusing on accountability, transparency, and sound policies that are responsive to the needs of the people.
    • Youth Engagement: Recognizing the potential of India’s youth, the government has launched initiatives like the “Voice of Youth” portal to encourage young people to contribute ideas for achieving the goals of Viksit Bharat.

    Economic Challenges

    • Weak Domestic Demand: Stagnant or declining demand for goods and services due to low-income growth, high inflation, unemployment, and the impact of the Covid-19 pandemic.
    • High Unemployment: Despite rapid growth, unemployment remains a serious issue, worsened by the pandemic. The unemployment rate in India rose to 8.1 per cent in April 2024 from 7.4 per cent in March 2024, according to CMIE’s Consumer Pyramids Household Survey. 
    • Poor Infrastructure: India lacks adequate infrastructure like roads, railways, ports, power, water and sanitation, hampering economic development. The infrastructure gap is estimated at around $1.5 trillion.
    • Balance of Payments Deterioration: India runs a persistent current account deficit, with imports exceeding exports. Exports and imports decreased by 6.59% and 3.63% respectively in 2022.
    • High Private Debt Levels: India has witnessed a significant rise in debt levels in recent years.
      • According to the Reserve Bank of India (RBI), the total non-financial sector debt reached 167% of GDP in March 2020, up from 151% in March 2016. 
      • Household debt in India rose to 40.10% of GDP in the fourth quarter of 2023, up from 39% in the previous quarter. 

    Military Challenges

    • Securing Borders: Despite conflicts with Pakistan and China, India has reasonably managed border security. However, the rapid rise of China poses economic and military challenges.
    • China’s Growing Influence: Almost all of India’s neighbours are moving closer to China, necessitating better policy and diplomacy to secure India’s interests and ensure regional stability.
    • Military Modernization and Resource Allocation: India’s dependence on foreign arms imports, despite efforts to promote self-reliance through initiatives like “Make in India,” highlights the need for a robust domestic defense industry.
      • The country has been the largest arms importer from 2018 to 2022, indicating ongoing challenges in achieving military self-sufficiency

    Suggestive measures: (Way forward)

    • Agricultural Reforms: Investment in agricultural research and development, irrigation, and land-lease markets is vital. Building value chains for perishables can enhance food security and adapt to climate challenges.
    • Nutritional Security: Transitioning from mere food security to nutritional security is crucial, addressing issues like child malnutrition, which affects 35% of children under five.
    • Support for Farmers: Implementing subsidies for pulses and other sustainable crops can encourage healthier diets and environmental benefits. The government should provide financial incentives to farmers to shift from water-intensive crops to pulses.
    • Infrastructure Development: Continued investment in infrastructure, including transportation and digital connectivity, is essential for economic growth and improving citizens’ quality of life.
    • Education and Skill Development: Reforms in education to prioritize skill development and innovation are necessary to prepare the workforce for emerging industries and ensure inclusive growth.
    • Healthcare Initiatives: Expanding access to affordable healthcare services nationwide is critical for enhancing public health and productivity.

  • The tyranny of inequality  

    Why in the News?

    A recent study by Thomas Piketty and colleagues highlights a dramatic rise in wealth and income inequality in India over the past few decades, with a sharp increase particularly from 2014 to 2022.

    The analysis from ” Gallup World Poll (GWP) Survey (2019-23)” for India  

    Note: The GWP measures corruption through individual perceptions, asking respondents whether they believe corruption is widespread.
    • Income Inequality: The survey data indicates a significant rise in income inequality, with the top 1% controlling over 40% of total wealth in India, a stark increase from 12.5% in 1980.
      • The top 1% of income earners now receive 22.6% of the country’s total pre-tax income, up from 7.3% in 1980.
    • Rent-Seeking Behavior: The persistence of rent-seeking behavior among wealthy investors, which diverts resources from productive uses to securing unwarranted gains from government entities.
    • Judicial Trust and Corruption: Trust in the judiciary can play a significant role in curbing corruption. Higher trust correlates with lower perceived corruption levels.
    • Mutual Fund vs Fixed deposits: Speculative investments, such as mutual funds, largely drive income inequality, while savings in fixed deposits and post offices help curb it.
    • Inequality promotes corruption: The study finds that higher income inequality causes widespread corruption, while greater confidence in the judiciary helps reduce it.

    What is our present methodology for counting inequality?

    • Piketty’s Measure: Thomas Piketty’s measure compares the income share of the top 1% to that of the bottom 50%. This highlights the growing disparity in income distribution effectively.
    • Consumption vs Income Inequality: Inequality is traditionally measured using consumption expenditure surveys by the National Sample Survey Office (NSSO). However, consumption inequality tends to be lower than income inequality.
    • Use of Multiple Data Sources: Researchers often combine data from various sources, including national accounts, tax data, and recent surveys like the Periodic Labour Force Surveys (PLFS) and Consumer Pyramid Household Survey (CPHS).
    • Gini Index and Other Metrics: The Gini index is frequently used to quantify inequality, but it has limitations, being less sensitive to changes at the income distribution extremes.

    Issues Associated with measuring income inequality:

    • Data quality and availability: There has been a noted decline in the reliability of household surveys since 2011-12, making it difficult to obtain accurate and comparable data. For example, The 55th NSS round showed a dramatic decline in poverty estimates, which many experts deemed misleading due to the survey’s methodological flaws.
    • Underreporting of wealth: Surveys may underreport wealthier households’ consumption, leading to inaccurate inequality assessments. For example, the Household Consumption Expenditure Survey (HCES) 2022-23 reported a significant drop in rural and urban poverty levels. However, critics argue that these figures may not accurately reflect the reality of wealthier households
    • Comparability with other countries: India’s reliance on consumption data rather than income data can result in mischaracterization as a low-inequality country in international comparisons.
    • Focus on labor income: Some reports focus only on labor income, ignoring other income sources and skewing the understanding of overall inequality. For example, studies have shown that the income share of the top 10% in India has grown significantly, while labour income alone does not reflect this concentration adequately
    • Complexity of income dynamics: Accurately assessing inequality is challenging due to the influence of economic policies, globalization, and market forces. For instance, Researchers have noted that the absence of comprehensive tax data beyond 2017-18 adds uncertainty to the analysis of income inequality trends

    Way forward: 

    • Improve Data Collection and Methodologies: There is an urgent need to enhance the quality and reliability of household surveys and other data sources.
    • Broadening Income Metrics Beyond Labor Income: To better capture the full spectrum of income inequality, it’s essential to include non-labor income sources, such as capital gains, property income, and speculative investments.

  • Banni Grasslands of Kachchh

    Why in the News?

    A study conducted by researchers at Kachchh University assessed the suitability of different areas in Banni for sustainable grassland restoration, with ecological value being the primary criterion.

    Restoration of Banni Grasslands: Highlights of the Study

    Recent Study:

    • Objective: A study conducted by researchers at KSKV Kachchh University assessed the suitability of different areas in Banni for sustainable grassland restoration, with ecological value being the primary criterion.
    • Need for restoration: Originally covering about 3,800 sq. km, the Banni grasslands have shrunk to about 2,600 sq. km.
    • Categories of Restoration Zones: The researchers divided the grassland into five categories based on restoration suitability:
      • Highly Suitable: 937 sq. km (36%)
      • Suitable: 728 sq. km (28%)
      • Moderately Suitable: 714 sq. km (27%)
      • Marginally Suitable: 182 sq. km (7%)
      • Not Suitable: 61 sq. km (2%)
    • Restoration Potential: The “highly suitable” and “suitable” zones, making up nearly two-thirds of the Banni grasslands, can be restored easily by providing adequate water sources.

    About Banni Grasslands:

    • The Banni Grassland is a salt-tolerant ecosystem located in the Kutch district of Gujarat, covering around 3,847 square km.
    • It is said to be Asia’s largest grassland (TOI).
    • The climate is arid and semi-arid, with extremely hot summers (temperatures above 45°C) and mild winters (12°C to 25°C), receiving 300-400 mm of annual rainfall mainly during the monsoon.
    • It is inhabited by pastoral communities like the Maldharis, who rely on livestock grazing (cattle, buffalo, and sheep) for their livelihood.
    • Agriculture is limited due to arid conditions, with some areas used for salt production.
    • Flora: Grasses such as Dichanthium, Sporobolus, and Cenchrus species, with salt-tolerant plants, shrubs, and trees like Acacia and the invasive Prosopis juliflora.
    • Fauna: Indian wolf, hyena, chinkara, Great Indian Bustard, flamingos, and various raptors, reptiles, and invertebrates.

    Read what IAS Benjo P Jose, AIR 59 has to say about his Mains Prep

    If you feel the only way to clear Mains is to memorize tonnes and tonnes of data and facts, then this session is for you.

    Brainstorming or answer thinking is a unique approach to UPSC Mains. It involves generating points for the answer while understanding both the explicit and implicit demands of the question, rather than simply writing from pre-prepared notes on the topic. Past toppers like IAS Gaurav Agarwal and IAS Pratyush Pandey have emphasized this approach.

    It moves away from traditional methods of making notes, revising them multiple times, and writing numerous tests, which can often be overwhelming for aspirants. Instead, the focus shifts to brainstorming PYQs. With practice, the time taken to think of every answer gradually reduces. This approach emphasizes interlinking points with other topics in the GS papers, making it a more creative and dynamic method for UPSC Mains answer writing.

    IAS Benjo Sir, AIR 59 this year, is probably the first topper in many years to have successfully used this approach again. This method will help you make your notes more compact, adding creativity and logic to your UPSC preparation. Join this masterclass to learn the art of structured brainstorming and how to integrate it with your existing study routine. The session will be held on 21st August, Wednesday at 7 PM.

    Q  How globalization has led to the reduction of employment in the formal sector of the Indian economy? Is increased informalization detrimental to the development of the country?  (UPSC IAS/2016)

    Q Examine the role of ‘Gig Economy’ in the process of empowerment of women in India. (UPSC IAS/2021)

    Mentor comment: The Karnataka Platform-based Gig Workers (Social Security and Welfare) Bill, which was introduced on June 29, 2024, aimed to regulate the welfare and rights of gig workers in the state. It is the second such legislation in India after the state of Rajasthan. The proposed ‘quota-for-local’ Bill in Karnataka aims to reserve a significant percentage of jobs for locals, mandating that 70% of non-management and 50% of management positions be filled by Kannadigas. This legislation has raised concerns about its impact on migrant workers, who comprise a substantial portion of the workforce in IT and gig economy jobs.

    Let’s learn!

    __

    Why in the News? 

    Karnataka’s Gig Workers Bill has raised concerns about its impact on migrant workers, which comprises a substantial portion of the workforce in IT and gig economy jobs.

    Key Features of the Bill:

    Rights Protection: The Bill is designed as a rights-based framework, ensuring gig workers have protections against unfair dismissals and arbitrary payment deductions.
    Social Security Fund: A welfare fund will be established, funded by a fee from aggregators based on gig workers’ earnings. This fund aims to provide social security benefits to registered gig workers.
    Contractual Clarity: Aggregators must provide clear contracts detailing termination grounds and must give a 14-day notice before contract changes.
    Grievance Redressal: The Bill mandates a two-level grievance redressal mechanism, requiring aggregators with over 50 workers to form an internal dispute resolution committee.
    Transparency in Operations: Aggregators must disclose parameters related to work allocation and automated decision-making processes affecting workers.

    How does the proposed ‘quota-for-local’ Bill impact migrant workers?

    • Job Opportunities: The bill could limit job opportunities for migrant workers, as companies would be required to prioritize local candidates. This may lead to a reduction in the already precarious employment options available to migrants, who often fill lower-skilled positions.
    • Increased Competition: The migrant workers might face intensified competition for fewer available roles, particularly in sectors where they have traditionally been employed, such as delivery services and hospitality.
    • Economic Migration: The bill could lead to a demographic shift in the labor market. Migrants may choose to relocate to states with more inclusive hiring practices, impacting the state’s economy and workforce diversity.
    • Exploitation Risks: The present Bill could make migrants more vulnerable to exploitation, as companies may feel less inclined to hire them, leading to further marginalization of these workers.
    • Industry Concerns: Business leaders and industry representatives have expressed concerns that the bill could deter investment and talent from flowing into Karnataka, potentially leading to job losses and reduced economic growth. The focus should be on skills rather than reservations.

    What measures can be taken to protect migrant workers from exploitation?

    • Right to Change Employers: States need to ensure that migrant workers have the freedom to change employers without facing penalties, which can reduce their vulnerability to abuse and exploitation.
    • Empower Migrant workers: The government/ Private sector needs to provide comprehensive information regarding workers’ rights, including recruitment processes, legal protections, and avenues for reporting abuse.
      • Strengthening labor laws and legal assistance with counseling services that protect migrant workers and ensure strict enforcement through regular inspections of workplaces is a need of the hour.
    • Social Security and Housing Access: States need to ensure that migrant workers have access to social services, housing, and healthcare, which can help mitigate their vulnerabilities.
      • NITI Aayog in its report ”India’s Booming Gig and Platform Economy” has said that fiscal incentives such as tax breaks or startup grants may be provided for businesses that provide livelihood opportunities where women constitute a substantial portion of their workers.
    • International Cooperation: Encourage countries to adopt and implement international standards and conventions that protect the rights of migrant workers, promoting safe and ethical recruitment practices.

    Conclusion: The Karnataka Bill, like the Code on Social Security, 2020 and the Rajasthan Act 2023, fails to address employment issues in India. This oversight needs a rightful strategy to look into the issue concerning the gig economy as well as the migration pattern in India in past decades.

  • Labor conditions in southern states  

    Why in the News?

    Migrant workers from various parts of India are gradually becoming a noticeable presence in the agricultural fields of Tamil Nadu’s Cauvery delta, often called the granary of South India.

    Migrants in Tamil Nadu’s Cauvery Delta

    • Labour Shortage in Agriculture: The Cauvery Delta, known as the granary of South India, is experiencing a significant shortage of farmhands as the younger generation moves away from agriculture. This has led to a reliance on migrant workers, particularly from states like West Bengal and Bihar, who are skilled in paddy transplanting and harvesting.
    • Economic Dynamics: Migrant labourers are filling the labour gap during agricultural seasons, working in groups and completing tasks more quickly than local labourers. They charge around ₹4,500 to ₹5,000 per acre, compared to local workers who earn ₹600 per day.
    • Sociocultural Integration: While there hasn’t been significant tension between migrant workers and local labourers, the integration of migrants into the agricultural workforce is still evolving.
      • Local labour unions acknowledge the presence of migrant workers but do not see it as a widespread issue yet, partly due to the ongoing mechanization of agriculture and changing job preferences among the local youth.

    Dependence on Migrant Workers in Kerala

    • Shift in Labor Sources: Kerala has seen a growing dependence on migrant workers from northern and eastern states, including West Bengal and Bihar, to fill labour shortages in various sectors, including agriculture.
      • A recent study by the Gulati Institute of Finance and Taxation estimated the number of inter-state migrant workers in Kerala at 2.5 million, equivalent to 7% of the state’s population.
    • Economic Factors: High wage differentials between Kerala and the migrants’ home states, along with a robust urban economy, have made Kerala an attractive destination for migrant labourers.

    External Migration from Uttar Pradesh to Maharashtra

    • High Migration Rate: Uttar Pradesh tops the list for inter-state job-related migration to Maharashtra, with over 5.7% of migrants moving for employment purposes between 2020 and 2021.
    • Concentration of Migrants: Within Maharashtra, districts such as Mumbai and Thane have the highest concentrations of migrants from Uttar Pradesh.

    How does the proposed ‘quota-for-local’ Bill impact migrant workers?

    • uction in the already precarious employment options available to migrants, who often fill lower-skilled positions.
    • Increased Competition: The migrant workers might face intensified competition for fewer available roles, particularly in sectors where they have traditionally been employed, such as delivery services and hospitality.
    • Economic Migration: The bill could lead to a demographic shift in the labor market. Migrants may choose to relocate to states with more inclusive hiring practices, impacting the state’s economy and workforce diversity.
    • Exploitation Risks: The present Bill could make migrants more vulnerable to exploitation, as companies may feel less inclined to hire them, leading to further marginalization of these workers.
    • Industry Concerns: Business leaders and industry representatives have expressed concerns that the bill could deter investment and talent from flowing into Karnataka, potentially leading to job losses and reduced economic growth. The focus should be on skills rather than reservations.

    What measures can be taken to protect migrant workers from exploitation?

    • Right to Change Employers: States need to ensure that migrant workers have the freedom to change employers without facing penalties, which can reduce their vulnerability to abuse and exploitation.
    • Empower Migrant workers: The government/ Private sector needs to provide comprehensive information regarding workers’ rights, including recruitment processes, legal protections, and avenues for reporting abuse.
      • Strengthening labor laws and legal assistance with counseling services that protect migrant workers and ensure strict enforcement through regular inspections of workplaces is a need of the hour.
    • Social Security and Housing Access: States need to ensure that migrant workers have access to social services, housing, and healthcare, which can help mitigate their vulnerabilities.
      • NITI Aayog in its report ”India’s Booming Gig and Platform Economy” has said that fiscal incentives such as tax breaks or startup grants may be provided for businesses that provide livelihood opportunities where women constitute a substantial portion of their workers.
    • International Cooperation: Encourage countries to adopt and implement international standards and conventions that protect the rights of migrant workers, promoting safe and ethical recruitment practices.

    Lack of Proper Data and Registration

    • Historical Data Gaps: The last comprehensive survey on internal migration was conducted as part of the National Sample Survey in 2007-08, with the Census 2011 data only partially released in 2020.
    • Absence of Real-Time Data: During the COVID-19 lockdown, the Indian government did not collect data on the deaths or job losses of internal migrants. The Ministry of Labour and Employment confirmed that it maintained no records of migrant workers who lost their jobs or lives during this period.

    Legislation: 

    The Inter-State Migrant Workmen (Regulation of Employment and Conditions of Service) Act, 1979 was enacted to protect the rights and regulate the conditions of service for migrant workers who move between states in India for employment.

    Implementation Challenges

    • Lack of Awareness: Many migrant workers are unaware of their rights under the Act, leading to exploitation and poor working conditions.
    • Inadequate Enforcement: There is often insufficient enforcement of the Act by state governments, resulting in widespread violations and the continued presence of migrant workers in informal and unregulated sectors.
    • Data Gaps: The absence of accurate data on the number of inter-state migrant workers complicates enforcement and the provision of services.

    Way forward: 

    • Promote Sustainable Employment and Skill Development in Source Regions: To reduce the over-reliance on migrant labour and address labour shortages in sectors like agriculture, the government should focus on creating sustainable employment opportunities in the migrants’ home states.
    • Promote Sustainable Employment and Skill Development in Source Regions: The government should create a real-time migrant data system linked with Aadhaar, enabling targeted policies, social security, and effective crisis response for internal migrants.

    Q Discuss the changes in the trends of labour migration within and outside India in the last four decades. (UPSC IAS/2015)

  • Do doctors need a Central protection Act?     

    Why in the News?

    Resident doctors across India are on strike, demanding safety laws after a young doctor was tragically raped and murdered at R.G. Kar Medical College in Kolkata on August 9.

    Why are Healthcare Workers Protesting?

    • Response to Violence: The protests were triggered by the brutal rape and murder of a young doctor at R.G. Kar Medical College and Hospital in Kolkata on August 9, 2024.
    • Demand for Safety: Healthcare workers are demanding laws and measures that ensure their safety while on duty.
    • Historical Context: Violence against healthcare workers is not a new issue in India. Previous incidents, such as the case of Aruna Shanbaug, a nurse who was sexually assaulted in 1973, underscore a long-standing pattern of violence in healthcare settings.

    Working Conditions of Junior Doctors, Interns, and Nurses

    • Poor Working Environment: Junior doctors, interns, and nurses often work in ill-lit and poorly secured hospital environments.
    • Long Shifts and Exhaustion: Many healthcare workers, including the victim of the recent incident, are subjected to excessively long shifts—in this case, a 36-hour duty shift—without adequate rest or safe spaces to recuperate.
    • Mental Health Concerns: The stressful working conditions, combined with the threat of violence, have raised significant concerns about the mental health and well-being of healthcare workers.

    Key Demands of the Protesters

    • Central Protection Act: The Indian Medical Association (IMA) is advocating for a Central protection law specifically for healthcare workers, similar to measures in other countries that classify assaults on medical staff as serious offenses.
    • Enhanced Security Measures: Protesters are calling for hospital security protocols that match those of airports, including the installation of CCTV cameras, deployment of security personnel, and improved lighting in hospital corridors and wards.
    • Safe Work Environment: There is a demand for immediate systemic reforms to improve working conditions, including better security arrangements and the establishment of healthcare facilities as safe zones.
    • Accountability and Justice: The IMA has requested a thorough investigation into incidents of violence against healthcare workers, with a focus on timely and professional handling of cases and ensuring that perpetrators face exemplary punishment.
      • Government Response: Following the protests, the Ministry of Health and Family Welfare issued an order mandating that any violence against healthcare workers must be reported and acted upon swiftly, with institutional FIRs to be filed within six hours of an incident.

    Sole responsible for the safety of Health workers:

    • State Governments: Health and law enforcement are primarily state subjects in India, meaning that state governments are primarily responsible for ensuring the safety of healthcare professionals. They are tasked with implementing laws, providing adequate security in hospitals, and ensuring a safe working environment for medical staff.
    • Central Government: The central government plays a role in formulating national policies and frameworks that support the safety of healthcare workers. 
      • Recent initiatives include the Ministry of Health and Family Welfare’s order mandating the filing of FIRs within six hours of any violence against healthcare workers, indicating a push for accountability and swift action.

    Way forward: 

    • Implement a Central Protection Law for Healthcare Workers: The government should fast-track the enactment of a Central law specifically designed to protect healthcare workers from violence.
    • Improve Working Conditions and Mental Health Support: Hospitals should prioritize creating safe and well-secured environments for healthcare workers, including reasonable shift hours, adequate rest periods, mental health support, and robust security protocols to prevent future incidents of violence.
  • Zoopharmacognosy: the study of how animals self-medicate

    Why in the News?

    Researchers highlighted the zoopharmacognosy (practice of self-medication) by a Sumatran orangutan using the plant Fibraurea tinctoria to treat a facial wound.

    What is Zoopharmacognosy?

    • Zoopharmacognosy is the study of how animals use natural substances like plants, soils, and insects to treat their own illnesses. 
    • The term was coined by ecologist D.H. Janzen from the University of Pennsylvania.
    • It shows that animals have an instinctive ability to find and use natural remedies. 

    Key Studies and Observations

    • Neanderthals: In 2012, a Nature publication found that Neanderthals in Northern Spain used plants like yarrow and chamomile to treat infections.

    Other Animal Species:

    • Primates: Chimpanzees eat bitter leaves, like Vernonia amygdalina, to get rid of intestinal worms.
      • Pregnant lemurs nibbling on tamarind leaves to aid milk production.
    • Reindeer: Reindeer eat mushrooms like Amanita muscaria, possibly to fight off parasites.
    • Birds: Starlings line their nests with antimicrobial plants to protect their young from diseases.
    • Elephants: Pregnant elephants in Kenya eat specific plants to help induce labor.
    • Dogs: Dogs chew grass and then vomit to clear their stomachs of infections.
