  • 253rd birth anniversary of Raja Ram Mohan Roy

    One of the most influential social and religious reformers of the 19th century, Ram Mohan Roy, born on May 22, 1772 in what was then Bengal Presidency’s Radhanagar in Hooghly district, would have turned 253 years today.

    Raja Ram Mohan Roy (1772-1833)

    Early life

    • Born into a prosperous upper-caste Brahmin family, Roy grew up within the framework of orthodox caste practices of his time.
    • Child-marriage, polygamy and dowry were prevalent among the higher castes and he had himself been married more than once in his childhood.
    • The family’s affluence had also made the best in education accessible to him.
    • The waning of the Mughals and the ascendancy of the East India Company in Bengal towards the end of the 18th century was also the time when Roy was slowly coming into his own.

    Academics

    • Roy knew Bengali and Persian, but also Arabic, Sanskrit, and later, English.
    • His exposure to the literature and culture of each of these languages bred in him a scepticism towards religious dogmas and social strictures.
    • He spent considerable time studying the Vedas and the Upanishads, but also religious texts of Islam and Christianity.

    Religious belief

    • He was particularly intrigued by the Unitarian faction of Christianity and was drawn by the precepts of monotheism that, he believed, lay at the core of all religious texts.
    • He wrote extensive tracts on various matters of theology, polity and human rights, and translated and made accessible Sanskrit texts into Bengali.
    • Rammohun did not quite make a distinction between the religious and the secular. He believed religion to be the site of all fundamental changes.
    • What he fought was not religion but what he believed to be its perversion.

    Roy, the first among liberals

    • Even though British consolidation of power was still at a nascent stage in India at the time, Roy could sense that change was afoot.
    • Confident about the strength of his heritage and open to imbibing from other cultures what he believed were ameliorative practices, Roy was among India’s first liberals.
    • He was simultaneously interested in religion, politics, law and jurisprudence, commerce and agrarian enterprise, Constitutions and civic rights, the unjust treatment of women and the appalling condition of the Indian poor.

    Establishment of Atmiya Sabha

    • In 1814, he started the Atmiya Sabha (Society of Friends), to nurture philosophical discussions on the idea of monotheism in Vedanta.
    • It aimed to campaign against idolatry, casteism, child marriage and other social ills.
    • The Atmiya Sabha would make way for the Brahmo Sabha in 1828, set up with Debendranath Tagore, Rabindranath Tagore’s father.

    Abolition of Sati, educational and religious reforms

    • He campaigned for the modernisation of education, in particular the introduction of a Western curriculum, and started several educational institutions in the city.
    • In 1817, he collaborated with Scottish philanthropist David Hare to set up the Hindu College (now, Presidency University).
    • He followed it up with the Anglo-Hindu School in 1822 and, in 1830, assisted Alexander Duff to set up the General Assembly’s Institution, which later became the Scottish Church College.
    • It was his relentless advocacy alongside contemporaries such as Ishwar Chandra Vidyasagar that finally led to the abolition of Sati under the governor generalship of William Bentinck in 1829.
    • Roy argued for the property rights of women, and petitioned the British for freedom of the press (in 1829 and 1830).
    • His Brahmo Sabha, that later became the Brahmo Samaj, evolved as a reaction against the upper-caste stranglehold on social customs and rituals.

    Perils of non-conformism

    • Roy, who was given the title of Raja by the Mughal emperor Akbar II, was no exception to the societal enmity.
    • Roy was also often attacked by his own countrymen who felt threatened by his reformist agenda, and by British reformers and functionaries, whose views differed from his.

    Conclusion

    • Roy’s work in the sphere of women’s emancipation, modernising education and seeking changes to religious orthodoxy finds new relevance in this time.
    • He was among the first Indians to gain recognition in the UK and in America for his radical thoughts.
    • Roy was unquestionably the first person on the subcontinent to seriously engage with the challenges posed by modernity to traditional social structures and ways of being.
    • Rabindranath Tagore called him a ‘Bharatpathik’ by which he meant to say that Rammohun combined in his person the underlying spirit of Indic civilisation, its spirit of pluralism, tolerance and a cosmic respect for all forms of life.

  • World’s most powerful Solar Particle Storm struck Earth 14,300 years ago

    Why in the News?

    Scientists have discovered that a massive solar storm hit Earth around 12,350 BC, making it the most powerful solar event ever detected.

    What are Solar Particle Storms?

    • About: A solar storm is a disturbance caused by solar flares or coronal mass ejections that release charged particles into space.
    • Solar Particle Storm: It is a type of solar storm where high-energy particles travel toward Earth, producing cosmogenic isotopes like radiocarbon.
    • Detection: These isotope spikes are recorded in tree rings and are known as Miyake events, which act as cosmic timestamps.
    • Impact: Though rare, solar particle storms can severely affect satellites, communication systems, and power grids.
    • Historical Events: Major solar particle storms were identified in AD 994, 663 BC, 5259 BC, and 7176 BC.
    • Carrington Event (1859): This was a major solar storm, but not a particle storm—it resulted from a different solar mechanism.

    How was the ancient storm detected?

    • Methodology: A solar storm from 12,350 BC was discovered using tree-ring data from the French Alps.
    • Event Strength: This storm was over 500 times stronger than the 2005 solar storm, the largest in the satellite era.
    • What are its implications?
      • Significance: This is the first known extreme solar event before the Holocene, predating the last 12,000 years of stable climate.
      • Modern Relevance: The discovery highlights the risks of future extreme solar activity on Satellite infrastructure and Space Application.
      • Significance: Miyake events improve the precision of archaeological dating, helping better understand ancient human history.

  • [21st May 2025] The Hindu Op-ed: Scheme-based workers, the struggle for an identity

     

    PYQ Relevance:

    [UPSC 2021] Examine the role of ‘Gig Economy’ in the process of empowerment of women in India.

    Linkage: While the PYQ focuses on empowerment and women within the gig economy, it aligns with the broader theme of identity and status challenges faced by workers in non-traditional/precarious employment structures, a challenge explicitly highlighted for SBWs and then linked to gig workers in the article.

     

    Mentor’s Comment: The central government employs millions of regular and contract workers, including around 60 million in schemes like ICDS, NRHM, and mid-day meals. These workers—such as Anganwadi workers, helpers, ASHAs, and mid-day meal staff—support children, mothers, and nutrition. They connect communities with public health and help improve school enrollment and overall health.

    Today’s editorial talks about the problems faced by Scheme-Based Workers (SBWs). This content is useful for GS Paper I (Women’s Issues) and GS Paper II (Social Justice).

    _

    Let’s learn!

    Why in the News?

    The recent developments surrounding Scheme-Based Workers (SBWs)—particularly Anganwadi workers, ASHAs, and MDM workers—have reignited the debate on labour identity, social security, and worker rights in India.

    Who are scheme-based workers (SBWs)?

    •  Workers employed under various government social welfare schemes but not formally recognized as government employees. Around 60 million workers across government schemes. Eg: Anganwadi Workers (AWWs), Anganwadi Helpers (AWHs), Accredited Social Health Activists (ASHAs) and Mid-Day Meal Workers (MDMWs).
    • ICDS (since 1975), National Rural Health Mission (NRHM), and Mid-Day Meal Scheme.

     

    What roles do they perform?

    • Childcare and Nutrition Services: SBWs play a vital role in early childhood care by ensuring nutritional support, immunization, and preschool education. Eg: Anganwadi Workers (AWWs) under the ICDS scheme provide nutrition and basic health services to children and lactating mothers.
    • Public Health Outreach: They serve as a crucial link between the public health system and rural communities, improving health awareness and access. Eg: ASHAs under the National Rural Health Mission (NRHM) assist in maternal care, vaccination drives, and promote institutional deliveries.
    • Educational and Nutritional Support in Schools: They help enhance school enrollment and retention by providing mid-day meals, which also address child malnutrition. Eg: Mid-Day Meal Workers (MDMWs) prepare and distribute meals in schools under the Mid-Day Meal Scheme.

    What challenges do SBWs face in gaining formal recognition and benefits?

    • Lack of Worker Status: SBWs are often classified as “volunteers” or “honorary workers” rather than formal employees, denying them recognition as government workers. Eg: The Supreme Court in State of Karnataka vs Ameerbi (2006) ruled that Anganwadi workers are not state employees as they don’t hold statutory posts.
    • Absence of Minimum Wages: Most SBWs receive honorariums instead of wages, which are far below minimum wage standards. Eg: Anganwadi workers and helpers across states earn as low as ₹4,500–₹9,000 per month, without alignment to state minimum wage norms.
    • No Social Security Benefits: SBWs are denied access to pensions, provident fund, maternity benefits, and health insurance. Eg: Despite working in public health, ASHAs are not covered under schemes like EPFO or ESI.
    • Policy Delay and Avoidance: Governments often cite financial burden or the need for long-term planning to delay regularisation. Eg: In 2016, the Labour Minister told Parliament that there’s no fixed timeline to implement ILC recommendations for SBWs.
    • Suppression of Collective Action: SBWs’ strikes are often met with state repression or legal barriers. Eg: Maharashtra invoked the Essential Services Maintenance Act (ESMA) in 2017 to curb Anganwadi workers’ right to strike.

    Why is the government reluctant to regularise SBWs?

    • Financial Burden: Regularising SBWs would significantly increase the government’s salary and welfare expenditure, making it fiscally unsustainable. Eg: The central government employs over 60 lakh SBWs, and converting them to regular employees would involve massive budgetary allocations for wages and benefits.
    • Policy Ambiguity: Successive governments delay decisions by citing the need for long-term policy formulation without committing to a timeline. Eg: In 2016, the Labour Minister told the Rajya Sabha that implementing Indian Labour Conference (ILC) recommendations requires indefinite planning.
    • Privatisation Push: The government aims to reduce its role in welfare delivery by promoting public-private partnerships, weakening the case for regularisation. Eg: There have been attempts to privatise the Integrated Child Development Services (ICDS), directly affecting the employment security of Anganwadi workers.

    How have trade unions and courts supported SBWs’ demands?

    • Union Mobilisation: Major trade unions have organised SBWs to demand minimum wages, worker status, and social security through strikes and negotiations. Eg: In March 2025, Anganwadi workers in Kerala ended a 13-day indefinite strike organised by unions like AITUC, BMS, and CITU demanding regularisation and fair pay.
    • Judicial Recognition: Courts have gradually recognised some labour rights of SBWs, even when earlier rulings were unfavourable. Eg: In Maniben Maganbhai Bhariya vs District Development Officer (2022), the Supreme Court ruled that Anganwadi workers are eligible for gratuity under the Payment of Gratuity Act.

     

    What are the policy implications of granting SBWs formal employee status?

    • Fiscal Burden: Recognising SBWs as formal employees would significantly increase the government’s expenditure on salaries, pensions, and social security. Eg: The central government is concerned about cost implications due to the growing number of SBWs (nearly 6 million), especially as population-linked schemes expand.
    • Policy Reorientation: Granting formal status would require new frameworks for recruitment, training, service conditions, and grievance redressal. Eg: The Gujarat High Court in 2024 directed the State and Centre to create a joint policy to regularise Anganwadi workers as Class III and IV employees.
    • Precedent for Other Informal Workers: Regularising SBWs could set a precedent for other informal or gig workers demanding similar recognition and protections. Eg: Like SBWs, gig workers (e.g., delivery partners) are also fighting for worker status and social security rights in courts and labour forums.

    Way forward: 

    • Enact Clear Policies: Governments should promptly create and implement policies to grant SBWs formal worker status with fair wages and social security benefits.
    • Strengthen Monitoring: Improve enforcement by regional bodies to ensure timely wage revisions, labour rights protection, and prevent exploitation of SBWs.

  • Seasonal Impact of Monsoons on Wind Power

    Why in the News?

    The onset of cool, moisture-laden monsoon winds offers not just relief but also a significant opportunity for wind energy generation.

    About the Indian Monsoon:

    • Origin: The word “monsoon” comes from Arabic ‘mausin’ or Malayan ‘monsin,’ meaning “season”.
    • Seasonal Wind Shift: Monsoons are seasonal winds that reverse direction with changing seasons.
    • Types:
      1. Southwest Monsoon: Blows from sea to land, bringing rainfall across most of India.
      2. Northeast Monsoon: Blows from land to sea, bringing rain mainly to southeast India.
    • Role of Tibet: The Tibetan Plateau heats up in summer, creating low pressure that draws in moist winds.
    • Ocean Influence: A high-pressure system in the southern Indian Ocean helps drive the southwest monsoon.
    • Atmospheric Factors: Influencers include the Subtropical Jet Stream, Tropical Easterly Jet, and ITCZ.
    • Other Drivers: The Somali Jet, Somali Current, Indian Ocean Dipole, and Walker Cell also affect monsoon behaviour.

    How does monsoon impact wind variability?

    • Changing Wind Speeds: Monsoon wind speeds vary in strength and direction over time and place.
    • Energy Planning: Wind behaviour prediction is crucial for renewable power management, especially wind energy.
    • Agricultural Demand: Kharif crops planted in June depend on monsoon, raising seasonal energy demand.
    • Wind Energy Output: In areas like the Western Ghats, 70% of wind energy is generated June–September.
    • Forecasting Tools: Numerical Weather Prediction (NWP) models provide high-resolution wind forecasts.
    • AI Models: Tools like Google’s MetNet3 use satellite and radar data to predict wind in remote areas.

    India’s Wind Energy: Capacity, Growth & Challenges

    • India became the 3rd largest wind and solar producer in 2024, after China and the US.
    • Installed wind capacity: 50 GW as of March 31, 2025.
    • In 2024, wind and solar contributed 10% of electricity—solar 7%, wind 3%; hydro added 8%, totalling 22% from clean sources.
    • Solar capacity grew by 24 GW in 2024, doubling 2023’s figure; wind grew by 3.4 GW.
    • Leading wind additions: Gujarat (1,250 MW), Karnataka (1,135 MW), Tamil Nadu (980 MW).
    • Top wind states: Tamil Nadu, Gujarat, and Maharashtra; targets: 140 GW wind and 500 GW non-fossil capacity by 2030.
    • Land Use & Capacity Utilization Factor (CUF): Wind farms occupy just 2% of land, allowing agriculture on the rest; CUF ranges between 16%–19%, with peak generation during monsoon months.

     

    [UPSC 2014] The seasonal reversal of winds is the typical characteristic of:

    Options: (a) Equatorial climate (b) Mediterranean climate (c) Monsoon climate * (d) All of the above climates

    (b) the number of children born to a couple in their lifetime in a given population.

    (c) the birth rate minus death rate.

    (d) the average number of live births a woman would have by the end of her child-bearing age. *

     

  • Dirang Geothermal Project

    Why in the News?

    The Centre for Earth Sciences and Himalayan Studies (CESHS) has successfully drilled India’s first geothermal production well in Dirang, located in Arunachal Pradesh’s West Kameng district.

    This could potentially make Dirang the first geothermal-powered town in the country.

    What is Geothermal Energy?

    • Geothermal energy is derived from heat stored in the Earth’s interior, primarily from the decay of radioactive elements.
    • It can be utilised for electricity generation, heating, and industrial applications.
    • It is considered a renewable energy source as the Earth continuously generates heat.

    About Dirang Geothermal Project:

    • This project in West Kameng, Arunachal Pradesh, is the first successful geothermal drilling site in Northeast India.
    • It is led by CESHS under the Arunachal Pradesh Department of Science and Technology, with support from the Ministry of Earth Sciences.
    • It is a medium-to-high enthalpy zone (~115°C), with a fault between quartzite and schist, enabling efficient, low-impact drilling.
    • The site was selected after two years of geochemical and structural surveys, and can support applications like agricultural drying, space heating, and controlled storage.
    • International partners include the Norwegian Geotechnical Institute, Geotropy ehf (Iceland), and Guwahati Boring Service for execution.

    India’s Geothermal Landscape:

    • The Geothermal Atlas of India (2022) identifies 381 thermally anomalous sites across the country.
    • India has an estimated geothermal potential of 10,600 MW, enough to power over 10 million homes.
    • Geothermal energy offers base load power, unlike intermittent solar and wind sources.
    • The first operational plant was a 20 kW binary cycle pilot in Manuguru, Telangana, developed by SCCL.
    • A 25 MW project in Khammam remains stalled due to tariff issues with the Andhra Pradesh Electricity Regulatory Commission.
    • In Puga Valley, Ladakh, ONGC resumed work in 2024 on a 1 MW pilot plant, after a 2022 hot water leak raised safety concerns.
    • In Dholera, Gujarat, geothermal energy is used for cooking and air conditioning at a temple, showing direct-use feasibility.
    • India has signed MoUs with Iceland (2007) and Saudi Arabia (2019), and included geothermal energy in the 2023 RETAP agreement with the United States.
