    Surat’s diamond industry struggles to sparkle amid geopolitical tensions

    Why in the News?

    Over the past 8-9 months, more than 50,000 workers in Surat have lost their jobs, and over 70 people have tragically taken their own lives in the past year, unable to bear the strain of unemployment and family responsibilities.

    Economic Impact of Geopolitical Tensions

    • Global Supply Chain Disruptions: The Russia-Ukraine war and Israel-Gaza conflict have disrupted the supply chain of raw diamonds. Russia, a major supplier of rough diamonds to Surat, faces Western sanctions, which have restricted the flow of diamonds into India.
    • Sanctions on Russian Diamonds: U.S. and European Union sanctions on Russian-origin diamonds, including polished diamonds processed in India, have significantly affected exports, particularly to Western markets like the U.S., EU, and Hong Kong.
    • Falling Demand: Global demand for polished diamonds has decreased in key markets such as the U.S., China, and Europe. This reduction in demand has led to a sharp decline in India’s diamond exports, plummeting from $23 billion in 2022 to a projected $12 billion by the end of 2024.
    • Price Drops: Polished diamond prices have fallen by 5-27% due to oversupply and lower demand, further worsening the industry’s financial outlook.

    Employment Challenges

    • Job Losses: Over 50,000 diamond workers have lost their jobs in Surat over the past eight to nine months due to factory closures and layoffs.
    • Wage Reduction: Workers who remain employed have experienced significant wage cuts. For instance, wages have dropped from ₹45,000-₹55,000 per month in 2021 to ₹25,000-₹30,000 now.
    • Suicides and Financial Distress: Financial strain has led to over 70 suicides among diamond workers in Surat, as they struggle with job losses, school fees, rent, and medical expenses for their families.
    • Lack of Government Support: Despite repeated appeals, there has been little substantial government assistance for unemployed diamond workers, leaving them with minimal social security or institutional support.

    Future Prospects and Support Measures

    • Shift to Alternative Employment: Many workers have shifted to other forms of employment, such as driving cabs, street vending, or returning to agriculture in their native regions, to make ends meet.
    • Welfare Demands: The Diamond Workers’ Union (DWU) has called for a special welfare package for workers, including financial support for their children’s education and healthcare expenses.
    • Appeals for Government Intervention: The industry, represented by groups like the DWU, is urging both the state and central governments to intervene. However, so far, industry associations have not formally sought government intervention for relief measures.

    Way forward: 

    • Government Support Package: The state and central governments should introduce targeted financial relief measures for affected diamond workers, including unemployment benefits, healthcare assistance, and educational support for children.
    • Diversification and Skill Development: Encourage skill development programs to help workers transition to alternative employment sectors, such as textiles, agriculture, or services, ensuring long-term economic resilience and reduced dependency on the diamond industry.
  • Health Sector – UHC, National Health Policy, Family Planning, Health Insurance, etc.

    Preparing for the next pandemic: what NITI Aayog report says

    Why in the News?

    Four years after the onset of Covid, an expert group formed by NITI Aayog has proposed the establishment of a comprehensive framework to handle future public health emergencies or pandemics effectively.

    Lessons Learned from COVID-19:

    • Gaps in Legal Frameworks: Existing laws like the Epidemic Diseases Act (1897) and National Disaster Management Act (2005) were insufficient for handling large-scale health emergencies. These laws lack clarity on definitions of epidemics and provisions for managing public health crises, drug distribution, and quarantine measures.
    • Delayed Response and Coordination: The COVID-19 pandemic exposed weaknesses in coordination between central and state governments, highlighting the need for a more organized response mechanism.
    • Inadequate Surveillance: Insufficient disease surveillance and early warning systems delayed the identification of threats. The role of zoonotic diseases, especially viruses linked to bat species, underscored the need for better monitoring of human-animal interactions.

    What specific recommendations does the NITI Aayog report make?

    • Enactment of PHEMA: Introduce the Public Health Emergency Management Act for a more robust legal framework to manage pandemics and other health emergencies.
    • Empowered Group of Secretaries (EGoS): Establish a central committee to oversee pandemic preparedness, governance, R&D, surveillance, and response efforts.
    • Strengthened Disease Surveillance: Create a national biosecurity and biosafety network and monitor human-animal interfaces, especially for zoonotic diseases.
    • Emergency Vaccine Bank: Develop a stockpile of vaccines for rapid access during health crises, sourced domestically or internationally.
    • Early Warning and Research Network: Build a forecasting and modelling network, along with Centres of Excellence (CoEs) to advance research on priority pathogens and preparedness.

    How can India enhance its pandemic preparedness framework? (Way forward)

    • Strengthening Legal and Institutional Frameworks: Enact a Public Health Emergency Management Act (PHEMA) and establish an Empowered Group of Secretaries for coordinated pandemic response.
    • Enhancing Surveillance and Early Warning Systems: Build a robust disease surveillance network, biosecurity system, and epidemiology forecasting for early detection and response to outbreaks.
    • Investing in Health Infrastructure and Vaccine Stockpiles: Develop public health cadres, boost healthcare infrastructure, and create an emergency vaccine bank for rapid deployment during health crises.

  • How India’s Temples are Run?

    Why in the News?

    As the Supreme Court hears petitions about the alleged adulteration of ghee in Lord Venkateswara’s Laddu Prasadam, many religious organizations have renewed their demand to free temples from government control.

    How are Religious Places managed in India?

    • Muslim and Christian places of worship are managed by community-run boards or trusts.
    • Hindu, Sikh, Jain, and Buddhist temples are often under government control.
      • Hindu temples make up the majority of the 30 lakh places of worship in India (2011 census).
    • Under Article 25(2) of the Constitution, the government can regulate economic, financial, or secular activities associated with religious practices.
      • This allows the state to enact laws concerning the administration of Hindu religious institutions.

    Examples of Government Control:

    • Tamil Nadu: The state’s Hindu Religious and Charitable Endowments (HR&CE) department manages temples.
    • Andhra Pradesh: The state controls the Tirumala Tirupati Devasthanams (TTD), including the Tirupati Temple.
    • Jammu and Kashmir: Enacted the Jammu and Kashmir Shri Mata Vaishno Devi Shrine Act, 1988, specifically to manage the Vaishno Devi Shrine in Katra, Jammu.
    • A portion of the income from offerings and donations is used for:
      • Temple administration
      • Maintenance of smaller temples
      • Welfare activities, including hospitals, schools, orphanages, and secular education.

    Historical Context of Government Control Over Temples

    • Ancient India: Temples have historically received land and wealth donations from kings and nobles, becoming centers of culture and economy. Larger temples often promoted agriculture and irrigation.
    • Medieval Period: Many temples were attacked and pillaged by invaders due to their immense wealth.
    • Colonial Era: Between 1810 and 1817, the East India Company enacted laws in Bengal, Madras, and Bombay to regulate temples and prevent the misuse of temple income and endowments.

    Colonial Laws:

    • Religious Endowments Act, 1863: Gave control of temples to committees, but the government maintained influence through judicial jurisdiction and other laws.
    • Madras Hindu Religious Endowments Act, 1925: Empowered provincial governments to oversee temple endowments and gave substantial powers to commissioners.

    Post-Independence Laws:

    • After Independence, many states enacted laws based on the Madras Hindu Religious and Charitable Endowments Act, 1951, which gave the government supervision over temples and allowed the appointment of an Executive Officer to manage temple affairs.
    • A similar law was passed in Bihar around the same time.

     

    Demand for Freeing Temples from Government Control

    • 1959: The Rashtriya Swayamsevak Sangh (RSS) passed its first resolution demanding that the Kashi Vishwanath Temple be returned to Hindus.
    • 1988: The Akhil Bharatiya Karyakari Mandal (ABKM) of the RSS called on state governments to hand over temples to representatives of Hindu devotees, arguing that government control was unfair and aimed at controlling temple funds.
    • 2021: The VHP passed a resolution in Faridabad demanding a central law to free temples from government control.

    Legal Position on Temple Control

    Courts have generally upheld government control over temples, although there have been arguments in favor of freeing temples.

    Key Judgments:

    • 1954 Shirur Mutt Case: The Supreme Court ruled that a law transferring control of religious institutions to another authority violates Article 26(d), which guarantees the right to manage religious property. However, the state can regulate the administration of religious or charitable institutions.
    • Ratilal Panachand Gandhi vs. The State of Bombay (1954): The Supreme Court affirmed that the right to manage religious institutions is fundamental, but the state can regulate trust properties through valid laws.
    • Pannalal Bansilal Pitti vs. State Of Andhra Pradesh (1996): The Supreme Court upheld a law abolishing hereditary rights over temple management and rejected the argument that such laws must apply equally to all religions.

    Recent Case:

    • In 2022, lawyer Ashwini Upadhyay filed a petition in the Supreme Court to free temples from government control. The SC remarked that under the current system, temples cater to broader social needs, and reversing this would return temples to their previous state as centers of wealth. Upadhyay withdrew his petition.

    BRCA Testing

    Why in the News?

    Angelina Jolie’s case highlighted hereditary breast and ovarian cancer (HBOC) after she underwent preventive surgeries due to a BRCA1 gene mutation.

    What is BRCA Testing?

    • BRCA testing is a genetic test that looks for mutations in the BRCA1 and BRCA2 genes.
    • These genes normally help repair DNA, but when they are mutated, they increase a person’s risk of developing certain cancers, particularly breast and ovarian cancers.
    • BRCA testing identifies whether a person has inherited these mutations, which can lead to Hereditary Breast and Ovarian Cancer (HBOC) and other cancers.
    • The test is done using a blood or saliva sample, which is collected and sent to a laboratory for analysis.
    • In the lab, next-generation DNA sequencing or other genetic analysis methods are used to examine the BRCA1 and BRCA2 genes for harmful mutations.
    • The test results can show whether a person has inherited a harmful mutation in these genes.
      • If the result is positive, it means they are at a higher risk for developing certain cancers.

    Issues with BRCA Testing

    • BRCA testing in India is expensive, costing between ₹15,000 to ₹30,000, which makes it unaffordable for many, particularly in lower-income populations.
    • Testing is often only offered to individuals with a family history of cancer, which misses about 50% of people who may have the mutations but no known family history.

    Significance for India

    • Breast cancer is the most common cancer among women in India, accounting for 27% of all cancer cases.
    • Women with BRCA mutations have up to a 72% risk of developing breast cancer.
      • Early identification allows for preventive measures, such as regular screenings or surgeries, which can reduce cancer incidence by up to 100%.
    • By increasing access to population-wide BRCA testing, India can improve early detection and reduce the burden of cancer on its healthcare system.
      • Early identification can also lower treatment costs and improve outcomes.

    In news: Arun River 

    Why in the News?

    The Arun River, which flows across Nepal and Tibet, is eroding rock and soil in its basin, leading to the rise of Mount Everest by up to 2 mm a year.

    How is Arun River making the Everest taller?

    The Arun River is contributing to the rise of Mount Everest through a process called isostatic rebound. Here’s how it works:

    1. River Incision:

    • The Arun River, which flows about 75 km from Mount Everest, is eroding large amounts of rock and soil from the surrounding landscape.
    • This process of erosion reduces the weight on the Earth’s crust in the Arun River basin.
    • A study by UCL suggests that the Arun River’s ability to carve out large amounts of rock and other materials may be due to it capturing another river or water system in Tibet.
    • This process is known as River Incision, where the river cuts downward into its bed, deepening its channel.
    • The erosion began to accelerate around 89,000 years ago when the Arun River merged with the Kosi River, removing large amounts of landmass and further reducing the weight on the region’s crust.

    2. Isostatic Rebound:

    • When the weight of the land (due to rocks, soil, or even ice) decreases, the Earth’s crust rises to balance the change.
    • This is similar to how a boat rises in water when heavy cargo is removed.
    • The removal of landmass in the Arun River basin allows the crust underneath Mount Everest to rise.

    About Arun River 

    • The Arun River originates in the Tibet Autonomous Region of China, where it is known as Phung Chu or Bum-chu in Tibetan.
    • It flows into Nepal and confluences with the Sun Koshi and Tamur River at Tribenighat, forming the Sapta Koshi River.
    • Tributaries:
      • Left tributaries: Yeru Tsanpo, Trakar-chu.
      • Right tributary: Barun River.
    • At the Nepal border, the Arun River is approximately 3,500 meters (11,500 ft) above sea level.
    • The river drains into the Koshi River, significantly contributing to the Sapta Koshi River system in Nepal.
    • It is the largest trans-Himalayan river in Nepal, playing a crucial role in supporting the region’s hydrology and ecosystems.
    • It provides around 37% of the total water in the Sapta Koshi system, following the Sun Koshi which contributes 44%.
    • Recently, the Arun-III Hydro Power Project (900 MW), which constructed with $6.95b Indian assistance, achieved a milestone with a tunnel breakthrough.

  • Tribes in News

    Tea tribes marginalized in Assam despite their contribution to the economy

    Why in the News?

    Recently, Jharkhand Chief Minister Hemant Soren urged Assam’s Himanta Biswa Sarma to grant ST status to tea tribes, he was also strategically countering the BJP’s campaign in election-bound Jharkhand.

    Demand for Scheduled Tribe Status

    • Recognition of Marginalization: The Jharkhand CM has emphasized that the tea tribes in Assam, numbering around 70 lakh, are marginalized despite their significant contributions to the state’s economy.
      • He has formally requested Scheduled Tribe (ST) status for these communities, which are currently classified as Other Backward Classes (OBCs) in Assam, limiting their access to essential government benefits and protections associated with ST status.
    • ST Status: The tea tribes meet the criteria for ST status due to their distinct cultural identity, traditional way of life, and vulnerability to exploitation.
      • Many members of these tribes are indigenous to Jharkhand and have historical ties to Assam, having migrated there during colonial rule to work in tea plantations.

    Which are the Tea Tribes in Assam?

    • Munda: Originating from the Chotanagpur plateau, they are one of the most prominent groups among the tea tribes in Assam.
    • Santhal: They have a rich cultural heritage and are known for their traditional music and dance.
    • Oraon: This group also hails from central India and has a strong presence in Assam’s tea gardens.
    • Gond: Primarily found in central India, Gonds are part of the tea tribes due to historical migration patterns.
    • Kurukh: This group is related to the Oraon and shares linguistic and cultural ties with them.
    • Bhumij: They were brought to Assam for labor in tea plantations.

    The criteria for a community to be recognized as a Scheduled Tribe (ST) in India:

    As established by the Lokur Committee and currently followed by the Office of the Registrar General of India (RGI), include:

    • Primitive Traits: Indications of a primitive lifestyle or cultural practices that are less developed compared to mainstream society.
    • Distinctive Culture: A unique cultural identity that differentiates the community from others, including language, traditions, and customs.
    • Geographical Isolation: Communities that are historically or currently isolated from the mainstream population, often residing in remote areas.
    • Shyness of Contact with the Community at Large: A tendency to avoid interaction with broader society, which may stem from historical marginalization.
    • Backwardness: Socio-economic disadvantages compared to the general population, including lower levels of education and economic development.

    How do the Tea Tribes contribute to the Economy?

    • Major Workforce: The tea tribes form the backbone of Assam’s tea industry, which is one of the largest in the world.
      • Approximately 53% of India’s total tea production comes from Assam, and a significant portion of this labor force comprises tea tribe members, particularly women.
    • Economic Dependence: It is estimated that around 20 lakh people (2 million) in Assam are directly or indirectly dependent on the tea industry for their livelihoods.
      • The wages earned by tea tribe workers are a primary source of income for many families within these communities.

    Cultural Heritage and Historical Injustices

    • Due to Cultural Displacement: The tea tribes face challenges in preserving their cultural heritage due to their classification as OBCs. This status affects their land rights and access to employment opportunities, leading to a loss of cultural identity.
    • Due to Socio-economic Challenges: Despite contributing significantly to Assam’s tea industry, the tea tribes suffer from poor living conditions, lack of educational facilities, and inadequate healthcare. 
      • They often live in poverty and face systemic barriers that prevent them from accessing government programs designed for marginalized communities. This situation reflects historical injustices stemming from colonial labor practices that uprooted them from their ancestral lands.

    Way forward: 

    • Granting ST Status: Expedite the process of granting Scheduled Tribe (ST) status to the tea tribes, which would provide them with legal recognition and access to special protections, reservations, and welfare schemes aimed at uplifting marginalized communities.
    • Improving Living Conditions: Implement targeted government programs to improve the living conditions of tea tribe communities, focusing on access to education, healthcare, and better infrastructure in tea plantation areas.
  • Climate Change Impact on India and World – International Reports, Key Observations, etc.

    The La Nina and North India’s pollution

    Why in the News?

    The delayed onset of La Niña and the late retreat of the monsoon have diminished hopes that Delhi’s residents might enjoy improved air quality this winter compared to previous years.

    What is Triple-dip La- Nina?

    Triple-dip La Niña refers to the rare occurrence of La Niña persisting for three consecutive years, causing prolonged cooler ocean temperatures in the Pacific and influencing global weather patterns, including stronger monsoons.

    How has the triple-dip La Niña phenomenon influenced air quality in North India?

    • No dispersion of pollutants: The delayed onset of La Niña has led to stagnant air and calm winds, preventing the dispersion of pollutants. In previous winters, La Niña helped improve air quality with stronger winds and atmospheric circulation.
    • Trapped air pollutants: The slower monsoon retreat resulted in extended periods of high humidity, reduced atmospheric mixing, and trapped pollutants near the surface, contributing to deteriorated air quality.

    What meteorological factors contributed to the observed anomalies in air quality?

    • Monsoon Retreat and Humidity: The delayed retreat of the monsoon contributes to prolonged periods of high humidity and calm winds. These conditions reduce atmospheric mixing, trapping pollutants near the surface and leading to elevated levels of PM2.5 and PM10.
    • Stagnant Winds: The absence of La Niña conditions results in stagnant surface winds, which hinder the dispersion of pollutants. This stagnation is particularly problematic given the regional emissions from stubble burning and other sources.
    • Stubble Burning: With prevailing north-north-westerly winds, stubble burning in Punjab and Haryana could significantly worsen Delhi’s air quality if it occurs at even half the intensity seen in previous years.

    What implications does this have for future climate and air quality management strategies?

    • Need for Broader Focus: There is a growing recognition that air quality management must shift from a localized emission-centric approach to one that considers larger meteorological patterns and regional airsheds.
    • Policy Recommendations: Policymakers should prioritize mitigating PM2.5 emissions over PM10, as PM2.5 poses greater health risks.
    • Integration of Climate Factors: Future air quality strategies should integrate climate change considerations, recognizing that local emissions are only part of the equation.

    Way forward:

    • Adopt Regional Airshed Management: Shift from a localized approach to a broader airshed strategy, accounting for meteorological patterns and regional pollution sources to improve air quality management.
    • Prioritize PM2.5 Mitigation and Climate Integration: Focus on reducing PM2.5 emissions, which pose higher health risks, and incorporate climate change factors into long-term air quality policies for comprehensive solutions.
