  • [ 15th April 2025] The Hindu Op-ed: Feminism for polarised times

    PYQ Relevance:

    [UPSC 2019] The long-sustained image of India as a leader of the oppressed and marginalised Nations has disappeared on account of its new found role in the emerging global order”. Elaborate.

    Linkage:  India’s historical role as a voice for the “Global South” and how its current global positioning might be perceived differently. This article argues for the Global South to take a leading role, which resonates with India’s past image.

     

    Mentor’s Comment:   While current talks on delimitation focus on its effect on power-sharing between states and the Centre, another key change depends on it — the rollout of the Women’s Reservation Bill, 2023. The Bill brought gender equality to the forefront of politics. However, this widespread acceptance has, in some ways, made open and critical discussion more difficult. A compassionate, inclusive feminism recognizes both structural and interpersonal challenges women face. It avoids oversimplifying gender struggles, respects men’s societal pressures, and promotes solidarity. 

    Today’s editorial discusses issues related to feminism. This content will be useful for GS Paper I in the Mains exam.

    _

    Let’s learn!

    Why in the News?

    A more compassionate approach to feminism could be the right strategy right now, as it helps gain support rather than create resistance.

    Why is there a caution against applying a heavy structural lens to interpersonal relationships?

    • Complexity of Relationships: Interpersonal relationships are multifaceted and often not reducible to power dynamics or oppression. Eg: A husband may expect dinner but also contribute financially, which shows mutual care rather than domination.
    • Risk of Oversimplification: Applying the structural lens too heavily risks oversimplifying relationships, reducing them to battles for power. Eg: A disagreement over household chores might be seen as oppressive when it could be a negotiation of responsibilities.
    • Love and Care Are Often Present: Many relationships are underpinned by love, care, and mutual respect, which should not be ignored in the analysis. Eg: A father who supports his daughter’s education despite societal barriers demonstrates care beyond structural oppression.
    • Men’s Experiences and Contributions: Men also face societal pressures, including financial and emotional burdens, which can reshape family dynamics. Eg: A man who works long hours in difficult conditions to support his family might experience public humiliation, while his wife remains insulated from such public pressures.
    • Potential for Alienation: Focusing solely on structural analysis may alienate people, particularly those who feel embattled, like many men. Eg: Men who feel misunderstood in feminist discourse, especially those at the margins, may disengage from efforts for equality.

    How can feminist discourse become more inclusive and compassionate?

    • Acknowledge Multiple Forms of Suffering: Feminism should recognize the varied experiences of suffering and responsibility faced by both women and men, especially from marginalized communities. Eg: Recognizing that men, particularly in low-income families, endure public humiliation due to financial pressures, while women often carry unpaid domestic responsibilities.
    • Avoid Oversimplifying Complex Dynamics: Instead of reducing all issues to power struggles, feminist discourse should appreciate the complexity of human relationships, where love, care, and duty often coexist with structural inequality. Eg: A couple might have disagreements over housework, but these can be opportunities for negotiation rather than a sign of patriarchal oppression.
    • Promote Solidarity, Not Antagonism: Feminist discourse should focus on creating solidarity, especially by addressing the emotional and economic pressures that shape men’s lives, inviting them to participate in gender equity efforts. Eg: Instead of criticizing men for their limitations, feminist discourse can encourage mutual understanding and support for gender equality.
    • Recognize the Interconnection of Personal and Political: Feminism should find a balance between the structural and the interpersonal, understanding that both need attention without conflating them. Eg: In rural areas, a woman may face different challenges from a financially independent urban woman, and addressing these separately helps focus on their unique struggles.

    Which aspects of current feminist narratives risk alienating both men and women, especially from marginalised backgrounds?

    • Oversimplification of Gender Struggles: Current feminist narratives often reduce complex interpersonal relationships to mere power struggles, ignoring the nuanced and varied experiences of individuals. This can alienate those who may not fit neatly into these narratives, particularly men from marginalized backgrounds who feel misunderstood. Eg: Depicting all men as perpetrators of patriarchy can alienate men who are struggling with their own economic and social pressures, leading to defensiveness rather than solidarity.
    • Blurring of Inequities: By merging vastly different forms of inequality, such as the struggles of financially independent urban women with those of rural women fearing violence, feminist discourse risks obscuring the real, context-specific challenges faced by each group. This can alienate individuals who feel their unique struggles are being overlooked. Eg: An urban woman’s struggles with household responsibilities may be portrayed in the same light as a rural woman’s safety concerns, which can cause friction and hinder support for both groups.
    • Antagonistic Tone Towards Men: A feminist narrative that is too focused on antagonism between the sexes, without acknowledging the emotional and economic pressures men face, can alienate men and prevent productive dialogue. This risks creating an “us versus them” mentality, undermining the potential for cross-gender solidarity. Eg: Men in low-income families, facing public humiliation due to financial hardship, may feel blamed for perpetuating patriarchal structures, even when they are also victims of societal pressures. This makes it harder for them to support feminist goals.

    What has steps taken by Indian Government? 

    • Legislative Reforms for Women’s Safety and Empowerment: The government has enacted laws to improve women’s safety and protect their rights. Eg: The Protection of Women from Domestic Violence Act (2005) was enacted to provide legal protection to women facing violence within the home. Additionally, the Criminal Law (Amendment) Act (2013) expanded the definition of sexual offenses and introduced stricter punishments for crimes like rape and acid attacks, in response to the Nirbhaya case.
    • Schemes for Economic Empowerment: The government has introduced various schemes aimed at economically empowering women, especially in rural and marginalized communities. Eg: The Pradhan Mantri Ujjwala Yojana (2016) provides free LPG connections to women from below-poverty-line families, reducing their dependency on traditional cooking methods that often expose them to health hazards. Similarly, schemes like Beti Bachao Beti Padhao focus on improving education and access to opportunities for girls.
    • Reservation and Affirmative Action in Education and Employment: The government has implemented affirmative action measures to enhance women’s participation in education and employment. Eg: The Reservation for Women in Local Governance mandates one-third of seats in Panchayats (local governing bodies) be reserved for women, encouraging their participation in political processes and decision-making. Furthermore, policies like the Maternity Benefit Act (2017) aim to protect women’s rights in the workplace by providing paid maternity leave.

    Way forward: 

    • Promote Intersectional Feminism: The government and society should adopt an intersectional approach to feminism, addressing the unique challenges faced by women from diverse backgrounds, including rural, urban, and marginalized communities. Eg: Tailoring policies like Beti Bachao Beti Padhao to address region-specific challenges, such as safety concerns in rural areas and educational disparities in urban areas, can create more inclusive support for all women.
    • Engage Men in Gender Equality Efforts: Foster dialogue and understanding by engaging men in discussions around gender equality, recognizing their societal pressures, and encouraging shared responsibility in family and community roles. Eg: Programs like #HeForShe can be expanded to include more men, emphasizing their role in supporting gender equity at home and in the workplace, helping to bridge the gap between feminist discourse and broader societal change.

  • Study finds a Shift in Peak Time of Maximum Rainfall

    Why in the News?

    A recent study published in Geophysical Research Letters revealed changes in the amount and timing of rainfall using GSMaP Data between 2001-2010 and 2011-2020.

    About Global Satellite Mapping of Precipitation (GSMaP)

    • GSMaP is a specialized precipitation product developed through collaboration between ISRO (Indian Space Research Organisation) and JAXA (Japan Aerospace Exploration Agency).
    • It provides high-resolution precipitation data with a 0.1° x 0.1° grid and one-hour temporal resolution, focusing on the Indian subcontinent since March 2000.
    • The data supports rainfall trend analysis, climate modelling, and water resource management.

    Study finds a Shift in Peak Time of Maximum Rainfall

    Key Findings of the Study:

    • Rainfall Trends:
      • West-Central India: Increased daily rainfall (2 mm/day) from 2011-2020 compared to 2001-2010.
      • Eastern India: A decrease of ~1 mm/day in rainfall during the same period.
      • Regional Shifts: Northeastern and eastern India saw decreased rainfall, while the Indo-Gangetic Plain and southern India experienced increases.
    • Vegetation & Soil Moisture:
      • West-Central India saw an increase in vegetation (NDVI from 0.2 to 0.4) and soil moisture linked to increased rainfall.
      • Eastern India had decreased soil moisture during the same period.
    • Shifts in Peak Rainfall Timing:
      • Indo-Gangetic Plain: Peak rainfall advanced by 2-4 hours.
      • West-Central India: Peak rainfall delayed by 1-2 hours.
    • Factors responsible for this Shift:
      • Higher soil moisture supports rainfall, while reduced moisture, particularly in eastern India, decreases rainfall.
      • Higher aerosol concentrations in polluted areas like the Indo-Gangetic Plain lead to earlier rainfall peaks.
      • Changes in atmospheric circulation, topography, and coastal influences also affect rainfall distribution and timing.
    [UPSC 2012] Consider the following statements:

    1. The duration of the monsoon decreases from southern India to northern India.

    2. The amount of annual rainfall in the northern plains of India decreases from east to west.

    Which of the statements given above is / are correct?

    (a) 1 Only (b) 2 Only (c) Both 1 and 2 (d) Neither 1 nor 2

     

  • What is Atmospheric River?

    Why in the News?

    Earlier this month, severe weather in the United States, including heavy rainfall, strong winds, and thunderstorms, was caused by an Atmospheric River.

    What is an Atmospheric River?

    • An atmospheric river is a narrow, fast-moving band of moisture and wind that transports large amounts of water vapor across vast distances.
    • They form when large-scale weather patterns align, creating channels of moisture transport from tropical oceans, guided by low-level jet streams toward the coast.
    • They typically span 402-606 km in width and can extend over 1600 km in length.
    • The most powerful atmospheric rivers transport moisture equivalent to the Mississippi River’s flow.
    • Example: The Pineapple Express, a well-known atmospheric river, transports moisture from Hawaii to the West Coasts of the U.S. and Canada.
    • The intense rainfall from atmospheric rivers leads to flooding, mudslides, and infrastructure damage, with wind speeds comparable to hurricanes.

    Impact and Climate Change:

    • Rising global temperatures cause more water to evaporate, and warmer air can hold more moisture.
    • For every 1°C increase, the atmosphere can hold 7% more moisture, leading to stronger storms.
    • Research indicates such events will likely grow longer and more intense.
    [UPSC 2023] With reference to the Earth’s atmosphere, which one of the following statements is correct?

    (a) The total amount of insolation received at the equator is roughly about 10 times of that received at the poles.

    (b) Infrared waves are largely absorbed by carbon dioxide that is concentrated in the upper atmosphere.

    (c) Infrared waves are largely absorbed by water vapour that is concentrated in the lower atmosphere.  

    (d) Ultraviolet rays are absorbed by the ozone layer lying in the ionosphere.

     

  • [12th April 2025] The Hindu Op-ed: The Beijing India Report as milestone and opportunity

    PYQ Relevance:

    [UPSC 2019] What are the continued challenges for women in India against time and space?

    Linkage: The challenges that women still face are a major concern under the Beijing Platform for Action and are likely to be reviewed in the Beijing India Report. Pointing out these ongoing issues shows how much more needs to be done to reach the goals of the Beijing Declaration.

     

    Mentor’s Comment:  It’s been 30 years since the Beijing Declaration set a global plan for gender equality across areas like education, health, and politics. In India, it led to key laws like the Domestic Violence Act and the POSH Act, and encouraged women’s economic empowerment. However, poor implementation still creates a gap between legal rights and the real experiences of women.

    Today’s editorial discusses how gender inequality and climate change are interconnected. This topic is relevant for GS Paper 1 (Women’s Issues), GS Paper 2 (Policy Making), and GS Paper 3 (Impact of Climate Change). It highlights the challenges women face due to climate change and the need for better policies to address these issues.

    _

    Let’s learn!

    Why in the News?

    The report lacks a strong link between climate and gender, and this needs to be fixed through policy improvements and changes at the grassroots level.

    Why does this report lack a strong link between climate and gender?

    • Limited Focus on Gender-Specific Impacts: The report fails to adequately highlight how climate change specifically affects women, especially in rural areas. Eg: It doesn’t emphasize the extra burden women face in collecting water or gathering fuel during droughts, which worsens due to climate change.
    • Insufficient Data on Gendered Vulnerabilities: The report lacks comprehensive data on the gendered impacts of climate change, leaving out how women are disproportionately affected by disasters and resource scarcity. Eg: It overlooks how climate-induced migration increases women’s vulnerability to gender-based violence.
    • Absence of Gender-Responsive Climate Policies: The report doesn’t propose clear actions for integrating gender into climate policies, limiting women’s participation in climate adaptation and decision-making. Eg: There are no specific recommendations for promoting women’s leadership in local climate action plans or agricultural adaptation strategies.

    What challenges do rural women face due to gender inequality and climate change?

    Challenge Impact on Rural Women Example/Evidence
    Education Disruption Climate-induced migration and household burdens force girls to drop out of school. In Dhanelikanhar village, Chhattisgarh, girls are leaving school due to displacement caused by climate stress and migration.
    Unpaid Care Work Resource scarcity increases women’s burden of water, fuel collection, and caregiving, limiting their economic opportunities. Arsht-Rock report: Rural Indian women work over 8 hours daily, with 71% of their labor unpaid, deepening gender inequality.
    Health Vulnerability Malnutrition, anaemia, and reproductive health issues rise due to food insecurity and lack of healthcare access. Over 50% of pregnant women in India are anaemic; food-insecure women are 1.6x more likely to suffer from anaemia.
    Livelihood Loss Extreme weather reduces agricultural output and affects non-farm livelihoods where women are largely employed. Climate change causes up to 33% income loss in rural areas, with women in non-farm sectors most affected.
    Exposure to Violence and Safety Risks Climate stress and resource conflicts heighten risks of intimate partner violence and general insecurity. A study shows every 1°C rise in temperature leads to 8% more physical violence and 7.3% more sexual violence against women in India.

    Why is a gender-climate lens vital for India’s sustainable future, as per the Beijing India Report 2024?

    • Inclusive Policy Design: A gender-climate lens ensures that women’s specific vulnerabilities are addressed in climate policies. Eg: Only 6% of climate policies globally mention women, leading to gender-blind strategies in India’s rural development.
    • Strengthening Resilience: Recognizing women’s roles in natural resource management and agriculture strengthens community resilience to climate shocks. Eg: Rural and tribal women preserve climate-resilient seeds, essential for adaptive farming during droughts and floods.
    • Reducing Inequality: Targeted climate budgeting and gender audits help close gaps in access to resources, services, and decision-making power. Eg: Women’s unpaid work, like water and fuel collection, could rise to 8.3 hours/day by 2050 without gender-responsive policies.
    • Boosting Food Security: Closing the gender gap in agricultural resources increases productivity and national food security. Eg: Empowering women farmers can raise farm yields by 20%-30%, feeding up to 150 million more people.
    • Empowering Local Leadership: Women-led climate initiatives promote local innovation, disaster preparedness, and sustainability. Eg: Women’s self-help groups in climate-vulnerable areas act as first responders during disasters and promote eco-friendly practices.

    What are the steps taken by the Indian government?

    • Inclusion in National Climate Frameworks: The government has integrated gender concerns into major climate policies like the National Action Plan on Climate Change (NAPCC) and State Action Plans (SAPCCs). Eg: Some SAPCCs include women’s role in sustainable agriculture and water management initiatives.
    • Legislative and Policy Support for Women’s Empowerment: Laws like the Protection of Women from Domestic Violence Act and POSH Act strengthen the overall gender rights framework, which intersects with climate resilience. Eg: These laws provide safety nets that support women’s participation in community and environmental activities.
    • Promotion of Women-Led Livelihoods in Rural Missions: Schemes like the National Rural Livelihoods Mission (NRLM) support women’s Self-Help Groups (SHGs) to engage in sustainable practices. Eg: Women SHGs in Odisha and Chhattisgarh are trained in climate-resilient farming and forest produce collection.

    Where should policies and budgets focus to support gender-responsive climate action? (Way forward)

    • Gender-Responsive Climate Budgeting: Policies must ensure budgets address the specific climate vulnerabilities of women and prevent greenwashing. Eg: Creating separate budget lines for women’s disaster relief and climate-resilient livelihood schemes in rural areas.
    • Climate Education and Skill Building: Invest in capacity building for women to participate in climate action and green jobs. Eg: Training rural women in solar panel installation or eco-friendly farming techniques.
    • Support Hubs and Safety Services: Establish community hubs that offer healthcare, disaster relief, and protection from gender-based violence. Eg: Setting up women-centric climate support centers in flood-prone regions of Assam.
    • Non-Farm Livelihood Diversification: Promote alternative income sources for women affected by climate-related agricultural losses. Eg: Funding mushroom farming or tailoring units for women in drought-hit Bundelkhand.
    • Inclusion in Local Governance and Decision-Making: Ensure women’s representation in local climate planning and governance bodies. Eg: Mandating women’s participation in State and District Climate Action Committees in Madhya Pradesh.

  • What are Mesoscale Convective System (MCS)?

    Why in the News?

    A recent study in Nature Geoscience suggests that soil moisture levels could help predict severe thunderstorms, like mesoscale convective systems (MCSs), especially in regions like India.

    About Mesoscale Convective Systems (MCS):

    • MCSs are larger than individual thunderstorms but smaller than larger weather systems like cyclones.
    • They typically cover areas between 100 to 1,000 km in diameter.
    • They form when warm, moist air rises, creating storms that feed off each other, growing in size and intensity as they move across the region.
    • They can cause flash floods, damaging winds, and severe thunderstorms, and are often responsible for large-scale weather events.
    • In tropical regions, MCSs account for 50 to 90 % of total rainfall, making them a major cause of severe weather-related damage.
    • A notable example is the March 2024 thunderstorm in West Bengal, which caused significant property damage and loss of life.

    Soil Moisture’s Role in MCS as per the Study:

    • Shifts in soil moisture can be detected two to five days before the formation of storms, providing critical lead time for early warnings in vulnerable regions.
    • Contrasting soil moisture levels over large areas (hundreds of kilometers) lead to changes in atmospheric conditions, including A notable example is the March 2024 thunderstorm in West Bengal, which caused significant property damage and loss of life.
    • Larger contrasts in moisture content between dry and wet regions cause greater temperature differences, which in turn lead to changes in wind direction and speed.
    • These variations contribute to turbulence, making storms more intense and spreading rainfall over a wider area.
    [UPSC 2013] During a thunderstorm, the thunder in the skies is produced by the

    1. meeting of cumulonimbus clouds in the sky 2. lightning that separates the nimbus clouds 3. violent upward movement of air and water particles

    Select the correct answer using the codes given below:

    (a) 1 only (b) 2 and 3 (c) 1 and 3 (d) None of the above produces the thunder

     

  • The crisis in India’s cotton production, and what can help

    Why in the News?

    India’s cotton production has dropped by 25% over the last 10 years because of the pink bollworm. Some seed companies have created new genetically modified cotton varieties that can resist this pest, but government rules are delaying their approval and use.

    Why has cotton output fallen despite Bt cotton’s earlier success?

    • Resistance Development in Pests: The pink bollworm (PBW), a monophagous pest, developed resistance to Bt cotton toxins (cry1Ac and cry2Ab) over time. Eg: A study published in Nature showed PBW resistance by 2014, just 12 years after Bt cotton’s introduction.
    • Pest Adaptability and Short Life Cycle: PBW’s short life cycle (25–35 days) allows multiple generations in one crop season, accelerating resistance buildup. Eg: In central India, PBW reached economic threshold levels by 2014, impacting yields.
    • Yield Stagnation and Decline: The national average lint yield rose to 566 kg/ha in 2013–14 but has fallen to around 436–437 kg/ha in recent years. Eg: This drop mirrors increased pest pressure and reduced effectiveness of Bt technology.
    • Increased Import Dependence: Falling domestic production has led to India importing more cotton than it exports. Eg: In 2024–25, imports are projected at 30 lakh bales vs exports of 17 lakh bales.
    • Lack of New GM Approvals: Regulatory and political hurdles have stalled the approval of next-gen GM cotton hybrids resistant to PBW. Eg: No new GM cotton hybrid has been commercialised since Bollgard-II in 2006.

    How has the pink bollworm turned India into a net cotton importer?

    • Destruction of Cotton Bolls and Lint Quality: PBW larvae bore into cotton bolls, feeding on seeds and lint, reducing both yield and fibre quality. Eg: This led to a production drop from 398 lakh bales (2013–14) to just 294 lakh bales (2024–25 projected) — the lowest since 2008–09.
    • Resistance to Bt Cotton: PBW developed resistance to the Bt toxins (cry1Ac and cry2Ab) used in GM cotton, making current hybrids ineffective. Eg: Resistance was first noted in central India around 2014, eventually spreading to southern and northern zones.
    • Decline in Exports, Rise in Imports: As production fell and quality declined, exports dropped and imports surged. Eg: In 2024–25, India is expected to import 30 lakh bales but export only 17 lakh bales, reversing its earlier status as a net exporter.

    Which new genetic technologies are Indian seed companies using to combat PBW resistance in cotton crops?

    • Introduction of Novel Bt Genes: Companies are using Bt genes not previously deployed in India to overcome existing PBW resistance. Eg: Bioseed Research India is conducting trials with its ‘cry8Ea1’ gene-based hybrid under the proprietary BioCotX24A1 event.
    • Use of Synthetic Bt Genes: Synthetic versions of Bt genes are engineered to enhance toxicity and overcome pest resistance. Eg: Rasi Seeds has developed hybrids expressing a synthetic cry1c gene for improved resistance to PBW.
    • Deployment of Chimeric Bt Genes: Chimeric genes combine segments of multiple Bt genes to create a novel protein with broader insecticidal action.Eg: Ankur Seeds, in collaboration with NBRI, is trialing cotton hybrids using a chimeric Bt protein from Event 519.

    When did the pink bollworm start crossing the economic threshold level in various cotton-growing zones of India?

    • Central Zone (Maharashtra, Gujarat, Madhya Pradesh): PBW crossed the ETL around 2014, marking the beginning of widespread yield loss in the heartland of cotton production. Eg: Farmers in Maharashtra began reporting severe PBW damage post-2014 despite using Bt cotton.
    • Southern Zone (Telangana, Andhra Pradesh, Karnataka, Tamil Nadu): The pest breached the ETL by 2017, affecting the second major cotton belt in the country. Eg: Telangana experienced major crop losses during the 2017–18 season due to PBW infestation.
    • Northern Zone (Punjab, Haryana, Rajasthan): PBW reached ETL in the northern states by 2021, completing its spread across all major cotton-growing regions. Eg: In 2021, Haryana reported pink bollworm infestation even in previously unaffected areas.

    How are regulatory hurdles affecting the commercialisation of new GM cotton hybrids in India?

    • Lengthy Approval Process: Multi-stage field trials (event selection, BRL-1, BRL-2) take years before commercial approval is granted. Eg: Bioseed’s ‘cry8Ea1’ GM cotton is still in BRL-1 trial phase, needing further years of testing before release.
    • Lack of New GM Approvals Since 2006: No new GM cotton hybrid has been approved for commercial cultivation since Monsanto’s Bollgard-II in 2006. Eg: Despite several companies developing PBW-resistant varieties, commercialisation remains stalled.
    • Opposition from States and Activist Groups: State-level permissions and activist resistance delay or block field trials, affecting research and rollout. Eg: Rasi Seeds and Ankur Seeds await approvals for first-year trials amid regulatory scrutiny and local objections.

    What advantages does India have in cotton production and trade?

    • Favorable Climate and Large Cotton-Growing Area: India has a vast area suitable for cotton cultivation, with diverse agro-climatic zones supporting long growing seasons. Eg: India is the world’s largest cotton producer, with major states like Maharashtra, Gujarat, and Telangana contributing significantly.
    • Low Export Duties Compared to Other Countries: India faces lower tariffs on its textile exports in key markets like the US, making its products more competitive. Eg: Under the US’s “reciprocal tariff” policy, Indian textile exports face only 27% duty, while China’s face 54% and Bangladesh’s 37%.

    Way forward: 

    • Accelerate Regulatory Approvals for Next-Gen GM Cotton: The government should streamline and fast-track the approval process for new GM hybrids with novel, synthetic, or chimeric Bt genes to restore cotton productivity and pest control efficacy. Eg: Timely clearance of Bioseed’s cry8Ea1 and Rasi’s synthetic cry1c cotton hybrids can help tackle PBW resistance.
    • Promote Integrated Pest Management (IPM) and Farmer Awareness: Combine genetic solutions with IPM strategies—crop rotation, pheromone traps, and timely pesticide use—to delay resistance buildup. Launch nationwide farmer education programs on early detection and field hygiene. Eg: Maharashtra’s IPM pilot schemes have shown promise in reducing PBW infestations when practiced consistently.

  • Hadean Protocrust

    Why in the News?

    A study from Macquarie University, Australia, suggests that plate tectonics may have started earlier than previously thought, with signs of it possibly existing in the Hadean protocrust even before the plates began to move.

    What is Hadean Protocrust?

    • The Hadean protocrust is the Earth’s first crust, formed within the first 200 million years of the planet’s creation.
    • During this time, the surface was mostly molten and constantly hit by space rocks, making it very hot and unstable.
    • Over time, parts of the molten surface began to cool and solidify, creating the first crust.

    Back2Basics: Hadean Aeon

    • The Hadean Aeon is the earliest geological eon in Earth’s history, lasting from about 4.6 billion to 4 billion years ago.
    • The surface was incredibly hot and volcanic activity was widespread, often described as “hellish.”
    • It was followed by the Archean Eon (about 4 billion to 2.5 billion years ago), characterized by the formation of Earth’s first stable crust, the beginning of plate tectonics, and the earliest known forms of life.
    • As the surface cooled, the thick parts of the crust formed the first continents, which moved on the hot, semi-fluid layer beneath them called the asthenosphere.

    Key Findings of the Recent Study:

    • The researchers found that the chemical signatures linked to plate tectonics might have appeared earlier, even when the Earth’s crust was still forming in the Hadean protocrust.
    • This discovery suggests that early movements of the Earth’s crust, similar to plate tectonics, could have happened before plates began to move as we know them today.
    • The study used models and experiments to support these ideas, but further research is needed to confirm these findings.

  • PM Modi at Jaya Sri Maha Bodhi

    Why in the News?

    PM Narendra Modi recently visited the Jaya Sri Maha Bodhi temple in the historic city of Anuradhapura, Sri Lanka.

    About the Jaya Sri Maha Bodhi Tree

    • The Jaya Sri Maha Bodhi tree is considered the oldest living cultivated plant globally.
    • It is believed to have grown from a branch of the original Bodhi Vruksha in Bodhgaya under which Gautam Buddha attained enlightenment.
      • This branch was carried to Sri Lanka by Sanghamitra, eldest daughter of Emperor Ashoka and his first wife, Queen Devi.
      • The original tree under which Buddha meditated was reportedly destroyed, possibly by Ashoka’s wife Tishyarakshita in some legends.
    • Sanghamitra’s arrival in Sri Lanka with the tree is commemorated during the Uduvapa Poya, a festival observed annually on a full moon night in December.

    Legend of Sanghamitra’s Journey to Sri Lanka

    • Sanghamitra, originally named Ayapali, lived from 282 BC to 203 BC.
    • Following the Third Buddhist Council (held in 250 BC in Pataliputra) during Ashoka’s reign, it was decided to send missionaries to various regions, including Sri Lanka, to spread Buddhism.
    • The mission to Sri Lanka was led by Mahinda (Mahendra), Ashoka’s son, who converted King Devanampiya Tissa of Anuradhapura to Buddhism.
    • After several royal ladies expressed interest in joining the Buddhist monastic order, Mahinda sent for his sister, Sanghamitra, to initiate them.
      • Both siblings lived in Anuradhapura for the rest of their lives.
    • She played a pivotal role in establishing the Order of Nuns (Bhikkhuni Sangha or Meheini Sasna) in Sri Lanka, which later spread to other Theravada Buddhist countries like Burma, China, and Thailand.
