From UPSC perspective, the following things are important :
Mains level: Diamond industry in India;
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.

From UPSC perspective, the following things are important :
Mains level: Management in Pandemic situation;
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.

From UPSC perspective, the following things are important :
Prelims level: Article 25(2) of the Constitution, Secularism
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.

From UPSC perspective, the following things are important :
Prelims level: BRCA1Testing
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.

Prelims level: Arun River, Isostatic Rebound

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.

From UPSC perspective, the following things are important :
Mains level: Issues related to STs
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.

From UPSC perspective, the following things are important :
Mains level: Climate change; Pollution; Impact of La-Nina;
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.

Prelims level: Initiative related to scientific research;
Why in the News?
In 2023, the government replaced numerous opaque science awards with the Rashtriya Vigyan Puraskar (RVP), a streamlined set with clear criteria. It aimed to address concerns about transparency by involving committees led by respected scientists.
Introduction of Rashtriya Vigyan Puraskar (RVP):
- In 2023, the government replaced multiple science-related awards with the RVP, a consolidated and streamlined set of awards.
- RVP introduced specific categories and clear eligibility criteria to enhance transparency and reduce opacity in the selection process.
- Committees led by reputed scientists were tasked with finalizing the awardees, a measure intended to address concerns about bureaucratic interference.
|
Concerns Over Selection Process:
- Chance of political interference: The modification of rules overnight and the omission of some scientists from the final list, despite being shortlisted by the RVP committee, created suspicion of political interference.
- Omission of the critic of Govt policy: Notably, some of the omitted scientists had previously criticized government policies, leading to concerns that the awards process might be used to marginalize dissenting voices within the scientific community.
Shift in Authority:
- Original Process: Initially, the RVP committee head had the authority to finalize the awardees.
- Recent Change: A last-minute rule modification allowed the committee head to only “recommend” the final list to the Science Ministry, increasing the possibility of government intervention in the selection process.
- Recognition Framework: The RVP awards are categorized into four main types: Vigyan Ratna for lifetime achievements, Vigyan Shri for distinguished contributions, Vigyan Yuva for young scientists, and Vigyan Team for collaborative efforts.
Impact on the Scientific Community
- Concerns Over Transparency: The modification of selection criteria just before the announcement of awardees has led to suspicions that political motives might influence who receives recognition.
- Notably, some scientists who were initially included in the recommended list were omitted from the final public announcement, prompting questions about whether political pressures were involved.
- Exclusion of Dissenting Voices: Many excluded scientists had previously expressed dissent against government policies. This trend suggests a troubling pattern where recognition is contingent upon alignment with governmental perspectives, potentially stifling academic freedom and critical discourse within the scientific community.
Way forward:
- Strengthen Transparency and Autonomy: Establish an independent, non-governmental oversight body to ensure that the selection process remains transparent and free from political interference.
- Safeguard Academic Freedom: Implement safeguards to prevent exclusion based on political or ideological views, ensuring that recognition is purely merit-based.

Prelims level: Physical Geography (Annular Solar Eclipse)

Why in the News?
An annular solar eclipse will be visible in parts of South America on October 2, 2023. It, however, will not be visible from India.
What is a Solar Eclipse?
- A solar eclipse occurs when the Moon moves between the Earth and the Sun, blocking the Sun’s light either fully or partially, casting a shadow on certain parts of the Earth.
- There are four types of solar eclipses:
-
- Total Solar Eclipse: When the Moon completely blocks the Sun, turning the sky dark. People in the path of a total solar eclipse can witness the Sun’s corona (its outer atmosphere), which is normally hidden by the bright sunlight.
- Annular Solar Eclipse: Occurs when the Moon is at or near its farthest point from Earth. The Moon does not fully cover the Sun, leaving a visible ring of fire around the Moon. This is what people in parts of South America will witness on October 2, 2023.
- Partial Solar Eclipse: Happens when the Moon blocks only a part of the Sun, giving it a crescent shape. During both partial and annular eclipses, areas outside the Moon’s umbra (the darkest part of its shadow) experience a partial eclipse. It is the most common type of solar eclipse.
- Hybrid Solar Eclipse: The rarest type, where the eclipse shifts between total and annular as the Moon’s shadow moves across the Earth. Some places see a total solar eclipse, while others see an annular one.
Frequency of Solar Eclipses
- A solar eclipse can only occur during the new moon, when the Moon and Sun are aligned on the same side of the Earth.
- A new moon happens approximately every 29.5 days because that is the time it takes for the Moon to orbit the Earth.
- However, solar eclipses don’t happen every month. They occur two to five times annually, but not every new moon results in an eclipse.
- Why don’t they occur every month:
- The Moon’s orbit around the Earth is tilted by about 5 degrees compared to the Earth’s orbit around the Sun.
- This means the Moon’s shadow usually misses the Earth.
- A solar eclipse only occur when the Moon crosses specific points in its orbit, called nodes, where the Moon’s orbit intersects the plane of Earth’s orbit around the Sun.
- When a new moon occurs at one of these nodes, a solar eclipse is possible.

Mains level: Adulteration issues in India;
Why in the News?
The ghee samples used by ‘Tirumala Tirupati Devasthanams’ for ritual offerings and ‘Laddu Prasadam’ were found to contain foreign fats, including fish oil, beef tallow, and lard, as per the NDDB’s analysis report.
What did the ALF of the National Dairy Development Board find in the Tirupati laddus?
- The Centre for Analysis and Learning in Livestock and Food (CALF) of the National Dairy Development Board found that ghee samples supplied to the Tirumala Tirupati Devasthanams (TTD) for preparing laddus were adulterated with various fats.
- Adulterants detected included:
-
- Plant-based fats: soybean, sunflower oil, rapeseed oil, linseed, wheat germ, maize germ, cotton seed, coconut, and palm kernel fat.
- Animal-based fats: fish oil, beef tallow, and lard (pig fat).
Existing Laws:
- The Indian Penal Code (1860) penalizes food adulteration under Section 272, but penalties are often minimal, leading to insufficient deterrence.
- The Food Safety and Standards Act, of 2006 aims to consolidate food safety regulations, but implementation remains weak due to inadequate resources and oversight.
Implementation Gaps:
- Despite robust standards set by the FSSAI, the actual enforcement is lacking. For instance, many tests that could detect sophisticated forms of adulteration are only sometimes conducted due to a lack of testing facilities and trained personnel.
- A study by the Centre for Science and Environment (CSE) highlighted that major brands of honey were found to be adulterated with undetectable syrups, raising concerns about the effectiveness of current testing protocols.
|
Why maintaining a good baseline data (specific to Indian conditions) is necessary?
- Biological Variation in Indian Cows: Baseline data specific to Indian cows is needed for accurate results. Indian cows may have different genetic and biochemical profiles compared to European cows, meaning the existing international standards for detecting adulteration (like the ‘s-values’) may not accurately reflect the composition of Indian cow ghee.
- Adulterants Unique to Local Conditions: The types of adulterants commonly used in India, such as certain vegetable oils or animal fats, may differ from those in other regions. Establishing baseline data for Indian adulterants would improve the precision of detecting the specific types of foreign fats used in India.
- Accurate Interpretation of Results: Without specific data on the composition of Indian cow ghee, it becomes difficult to interpret the results from methods like gas chromatography. Customized baseline data ensures that the detection methods yield accurate and meaningful conclusions in the Indian context.
Way forward:
- Strengthen Enforcement Mechanisms: Increase resources for testing facilities and train personnel to implement FSSAI standards more effectively, ensuring regular checks for sophisticated adulteration.
- Develop India-Specific Testing Protocols: Create testing standards based on baseline data specific to Indian cows and local adulterants to improve accuracy in detecting food adulteration.

From UPSC perspective, the following things are important :
Prelims level: Swachh Bharat Mission (SBM) Urban 2.0;
Mains level: Solid Waste Management; Urbanization issues at Local governance; Landfill issues in India;
Why in the News?
In the third year of the five-year Swachh Bharat Mission (SBM) Urban 2.0, larger cities have yet to clear land at half of their landfill sites. According to government sources, only 38% of the total waste has been remediated so far..
Present State of Cities in India (related to legacy landfills):
- Inadequate Progress in Waste Remediation: Three years into Swachh Bharat Mission (SBM) Urban 2.0, only 38% of the waste in legacy landfill sites across major cities has been remediated. About 62% of garbage still remains unprocessed, and 65% of the land has not been cleared.
- Slow Progress in Large Cities:
- In major cities with populations over 1 million, 35 out of 69 landfill sites have not had any land cleared.
- Deonar landfill in Mumbai, the largest in India, has not seen any remediation or land clearance.
- In Ahmedabad’s Pirana landfill, 48% of the total area has been cleared, while in Delhi’s Ghazipur and Bhalaswa landfills, waste remediation has begun, but no land has been reclaimed yet.
- Challenges with Legacy and Fresh Waste: Legacy landfills remain a persistent issue as fresh waste is still being deposited at the same sites undergoing remediation. This cycle hampers progress, as more fresh waste offsets the clearance of older waste, making remediation efforts inefficient.
Note: The Swachh Bharat Mission – Urban 2.0 (SBM-U 2.0), launched on October 1, 2021, aims to achieve a “Garbage Free” India by 2026. It focuses on sustainable sanitation, effective waste management, and enhancing urban cleanliness through initiatives like door-to-door waste collection and remediation of legacy dumpsites. |
What are the cities expected to do with reclaimed land?
- Reuse Plans for Cleared Land: According to SBM Urban 2.0 guidelines, cities are expected to reuse cleared land after bioremediation for productive purposes such as:
- Refuse Derived Fuel (RDF): Waste is processed into RDF for use in waste-to-energy plants.
- Construction and Demolition Waste Recycling: Cleared waste is recycled for infrastructure projects.
- Bio-soil: Reclaimed bio-soil is used for road construction or other land development projects.
- Limited Action on Reuse: Despite these plans, the amount of land reclaimed from garbage dumps remains minimal in many cities, and detailed data on how reclaimed land is being utilized is lacking. As of now, the focus remains on remediation rather than immediate land reuse.
Way forward:
- Develop Alternative Waste Processing Sites: Cities must create dedicated facilities to manage fresh waste separately from legacy landfills to avoid offsetting progress and ensure efficient remediation.
- Accelerate Land Reuse Plans: Prioritize the swift repurposing of reclaimed land for productive uses, such as waste-to-energy plants, construction material recycling, and bio-soil applications, ensuring sustainable urban development.

From UPSC perspective, the following things are important :
Prelims level: Issues related to manual scavengers;
Why in the News?
Government data from over 3,000 urban local bodies across 29 States and Union Territories shows that 91.9% of the 38,000 sewer and septic tank cleaners profiles belong to SC, ST, or OBC communities.
What are the socio-economic conditions of workers engaged in sewer and septic tank cleaning?
- Demographics: A significant majority (91.9%) of the 38,000 profiled workers belong to marginalized communities: 68.9% Scheduled Castes (SC), 14.7% Other Backward Classes (OBC), 8.3% Scheduled Tribes (ST), and 8% from the general category.
- Employment Status: The workforce largely comprises low-income individuals engaged in hazardous, low-status jobs, reflecting persistent caste-based disparities.
- Capital Subsidies support: Since the launch of the NAMASTE program, ₹2.26 crore in capital subsidies have been distributed to 191 beneficiaries, indicating some financial support for transitioning into self-employment.
How effective are current policies and rehabilitation schemes for sanitation workers?
- NAMASTE Programme: Aimed at mechanizing sewer cleaning and providing safety training and equipment, the program is a replacement for the Self-Employment Scheme for Rehabilitation of Manual Scavengers (SRMS).
- Enumeration Process: Over 3,326 urban local bodies (ULBs) are involved, with 38,000 workers profiled so far. However, 283 ULBs reported zero workers, suggesting that the profiling might not be comprehensive or that many workers are unrecognized.
- Rehabilitation Success: Out of 58,098 identified manual scavengers under the previous SRMS scheme, 97.2% were from SC communities. While cash transfers of ₹40,000 were provided, only a fraction pursued skills training or loans for alternative livelihoods.
What are the challenges?
- Social Stigma: Predominantly from marginalized communities (SC, ST, OBC), these workers face discrimination, limiting their access to better job opportunities and social mobility.
- Health Risks: Exposure to hazardous working conditions leads to significant health risks, with a high mortality rate (377 deaths from 2019 to 2023) due to unsafe practices.
- Ineffective Rehabilitation: Current policies and support programs lack comprehensive coverage, leaving many workers unrecognized and limiting the effectiveness of financial assistance and training initiatives.
What are the health risks and safety measures for workers in hazardous cleaning roles?
- Hazardous Working Conditions: Between 2019 and 2023, 377 workers died from hazardous cleaning activities, highlighting the extreme risks associated with sewer and septic tank cleaning.
- Safety Training: The NAMASTE program aims to provide safety training for workers to minimize health risks, but the effectiveness of such training needs further evaluation.
- Equipment and Mechanization: The goal is to transition workers from manual cleaning to mechanized processes, reducing their exposure to dangerous conditions and improving overall safety.
Way forward:
- Comprehensive Training and Support Programs: Enhance the effectiveness of the NAMASTE program by providing robust safety training and resources for workers, coupled with extensive outreach to ensure all workers are identified and supported, including those currently unrecognized.
- Promotion of Mechanization and Safety Standards: Accelerate the mechanization of sewer cleaning operations to reduce health risks, and establish strict safety standards and regulations to protect workers, ensuring regular monitoring and enforcement of these standards.

From UPSC perspective, the following things are important :
Prelims level: Neutrino Fog
Why in the News?
The LUX-ZEPLIN (LZ) experiment revealed that as we continue to push the boundaries of dark matter detection, the issue of neutrino fog becomes increasingly significant.
What is the LUX-ZEPLIN (LZ) Experiment?
- The LUX-ZEPLIN (LZ) experiment is a cutting-edge dark matter detection project located deep underground at the Sanford Underground Research Facility in South Dakota, USA.
- It is one of the most sensitive experiments in the world designed to detect dark matter particles, which are believed to make up about 85% of the matter in the universe but have not yet been directly observed.
- The heart of the LZ experiment is a tank filled with 10 tonnes of liquid xenon, a very dense and pure material.
- The idea is that if a dark matter particle collides with a xenon atom, it will produce a tiny burst of light and free electrons.
- These interactions are then detected by sensitive equipment surrounding the xenon.
- The experiment is located 1.5 km below the Earth’s surface.
|
What is Neutrino Fog?
- Neutrinos, often referred to as “ghost particles,” are subatomic particles with nearly zero mass and no electric charge.
- “Neutrino Fog” refers to the interference caused by neutrinos—subatomic particles that rarely interact with matter—in dark matter detection experiments.
- Neutrinos are produced naturally in the Sun’s core, supernovae, and even Earth’s atmosphere.
- Though they pass through most matter undetected, their weak interactions can cause small disturbances in highly sensitive detectors.
- As dark matter detectors become larger and more sensitive, they are more likely to detect neutrinos, leading to a “fog” of signals that can obscure or mimic potential dark matter interactions.
PYQ:
[2015] In the context of modern scientific research, consider the following statements about ‘IceCube’, a particle detector located at South Pole, which was recently in the news:
1. It is the world’s largest neutrino detector, encompassing a cubic kilometre of ice.
2. It is a powerful telescope to search for dark matter
3. It is buried deep in the ice.

Prelims level: Hepatitis E Virus (HEV)
Why in the News?
Recent research indicates that pigs may act as a transmission vehicle for a strain of the hepatitis E virus (HEV) commonly found in rats, known as Rocahepevirus ratti, or rat HEV.
Role of Pigs in Transmission
- HEV Reservoir: Pigs naturally carry hepatitis E virus (HEV), particularly strains that can infect humans.
- Transmission via Pork: Humans can contract HEV by consuming raw or undercooked pork from infected pigs.
- Environmental Contamination: Infected pigs shed HEV in faeces, contaminating the environment and water sources, potentially spreading the virus to humans.
- Poor sanitation in pig farms facilitates HEV transmission between pigs and increases the risk of human infection through the food chain.
- Cross-Species Transmission: Pigs may also act as intermediaries for rat HEV, transmitting the virus from rats to humans in farm environments.
|
About Hepatitis E Virus (HEV):
- Hepatitis E is caused by the Hepatitis E Virus (HEV), which is a positive-sense, single-stranded, non-enveloped RNA virus.
- HEV is classified under the family Hepeviridae, genus Orthohepevirus.
- It was first identified during an outbreak among Soviet soldiers in Afghanistan in 1983.
- The earliest well-documented HEV epidemic occurred in New Delhi, India, in 1955, retrospectively identified as HEV.
-
- The primary route of transmission is fecal-oral, especially through contaminated water and food.
- Zoonotic transmission is possible with genotypes 3 and 4, commonly spread through undercooked meat or direct animal contact.
-
- Jaundice, nausea, fatigue, and elevated liver enzymes.
- Severe cases can lead to liver failure, especially in pregnant women and immunocompromised individuals.
-
- A vaccine, HEV 239, is approved for use in China, but no vaccine is widely available or approved in most countries, including the United States.
- There is no specific antiviral treatment for acute HEV.
- Prevention relies on improved sanitation, safe drinking water, and proper food handling.
PYQ:
[2019] Which one of the following statements is not correct?
(a) Hepatitis B virus is transmitted much like HIV.
(b) Hepatitis B, unlike Hepatitis C, does not have a vaccine.
(c) Globally, the number of people infected with Hepatitis B and C viruses are several times more than those infected with HIV.
(d) Some of those infected with Hepatitis B and C viruses do not show the symptoms for many years. |
