Ladakh gets new policies on quota, domicile status


Context & Background

  • Ladakh became a Union Territory (UT) after the abrogation of Article 370 in August 2019.
  • Local civil society groups have long demanded constitutional safeguards for Ladakh’s culture, demography, land, and jobs (similar to Article 371 or Sixth Schedule protections).
  • The Centre has now introduced several key policy reforms in response.

Relevance : GS 2(Federalism , Governance)

Reservation Policy Changes

  • Total Reservation Cap Raised:
    • Earlier: Capped at 50% (as per 2004 J&K Reservation Act).
    • Now: Raised to 85%, excluding EWS quota.
    • With 10% for EWS, the total reservation hits 95%, among the highest in India.
  • Scheduled Tribes Focus:
    • 80% of jobs likely to be reserved for STs, reflecting Ladakh’s majority tribal population.
  • Comparison:
    • Meghalaya: 85% for SCs/STs.
    • Arunachal Pradesh: 80% for STs.

Domicile Policy

  • To qualify as a domicile:
    • One must have resided in Ladakh continuously for 15 years since October 31, 2019 (UT foundation day).
    • Applies even to children of Central government officials.
  • Implication:
    • Tightens eligibility for government jobs and other benefits.
    • Aimed at preserving Ladakhi identity and limiting demographic changes.

Language Policy

  • Official languages of Ladakh now include:
    • English, Hindi, Urdu, Bhoti, and Purgi.
    • Bhoti and Purgi are local languages, reflecting the cultural and linguistic diversity of the region.

Changes in Hill Council Composition

  • One-third reservation for women in hill councils (LAHDC Leh and Kargil).
    • To be implemented on a rotational basis.
    • Boosts women’s political representation in Ladakh’s local governance.

Broader Significance

  • Responds to the socio-political concerns of Ladakhi stakeholders.
  • Enhances affirmative action, local autonomy, and cultural preservation.
  • Indicates Centre’s decentralized approach to governance in tribal-majority UTs.
  • Could serve as a model for region-specific governance policies elsewhere in India.

IISc researchers develop artificial metal-based nanozyme that prevents excess blood clotting


Research Context & Objective

  • Conducted by: IISc researchers, led by Prof. G. Mugesh (Dept. of Inorganic and Physical Chemistry).
  • Objective: To prevent abnormal blood clotting (thrombosis) linked to conditions like pulmonary thromboembolism (PTE) and COVID-19.

Relevance : GS 2(Health) ,GS 3(Technology)

Understanding the Problem

  • Normal Blood Clotting (Haemostasis):
    • Triggered by injury to blood vessels.
    • Platelets cluster to form a clot, activated by agonists like collagen and thrombin.
  • Abnormal Clotting (e.g., in PTE, COVID-19):
    • Caused by oxidative stress and excess Reactive Oxygen Species (ROS).
    • ROS leads to over-activation of platelets, forming harmful clots (thrombosis).
    • Thrombosis contributes to ischemic events, strokes, and deaths.

Nanozyme Development

  • Developed: Redox-active nanomaterials mimicking natural antioxidant enzymes.
  • Function: Scavenge ROS to regulate oxidative stress and prevent platelet over-activation.
  • Synthesis: Achieved via controlled chemical reactions using small molecular building blocks.

Key Findings

  • Tested different sizes, shapes, and morphologies of nanozymes.
  • Platelets were isolated and activated using physiological agonists in lab settings.
  • Spherical-shaped Vanadium Pentoxide (VO) nanozymes showed the highest efficacy in preventing excess aggregation.

Medical Significance

  • Potential to treat or prevent:
    • Pulmonary Thromboembolism (PTE)
    • Thrombosis linked to COVID-19
    • Ischemic stroke (next phase of research)
  • Offers an alternative to conventional anticoagulants with a more targeted approach via ROS modulation.

Wider Implications

  • Represents a biomimetic therapeutic approach — using synthetic materials to mimic natural enzyme functions.
  • Opens avenues in nanomedicine for targeted, controlled therapies.
  • Can reduce side-effects typically associated with broad-spectrum blood thinners.

A ban, a split verdict, and a health concern


Mustard Oil in India: Context

  • Third-most consumed edible oil in India.
  • Extracted from Indian mustard crop, high in erucic acid (40–54%).
  • Health concerns exist due to high erucic acid, especially in Western countries.

Relevance : GS 2(Governance) ,GS 3(Agriculture)

Two Major Policy/Judicial Decisions

  1. FSSAI Ban (2021):
    1. Banned blending of mustard oil with other edible oils.
    1. Aim: To prevent adulteration and boost domestic mustard production.
    1. Blending allowed under law up to 20% but was misused (industry blends up to 50%).
  • Supreme Court Verdict (2024):
    • Struck down approval of GM mustard (DMH-11).
    • Reason: Insufficient health impact assessment.
    • Split verdict; health safety concerns cited by one of the judges.

Health Concern: Erucic Acid

  • Present in high quantity in Indian mustard oil (40–54%).
  • International limit: Less than 5% (U.S., Canada, Europe).
  • Animal studies: High erucic acid linked to heart issues, liver and kidney damage.
  • Human impact: No conclusive evidence, but stigma and strict regulations abroad.
  • Alternative abroadCanola oil (developed in Canada) with <2% erucic acid.

GM Mustard (DMH-11): Prospects and Benefits

  • Lower erucic acid content (30–35% vs 40–54%).
  • Higher yield potential.
  • Reduces need for blending and dependency on imported edible oils.
  • India’s edible oil import bill: $20.56 billion (NITI Aayog).
  • Scientific achievement: Comparable to Western low-erucic cultivars.
  • Needs further R&D to bring levels below 5%.

Blended Mustard Oil: Pros and Cons

Advantages:

  • Dilutes erucic acid content.
  • Rich in unsaturated fats → improves cholesterol profile (↑ HDL, ↓ LDL).
  • Practical in absence of low-erucic domestic cultivars.

Concerns:

  • Rampant adulteration (FSSAI 2020 survey: 24.21% samples failed quality checks).
  • Mustard oil had highest adulteration rates.
  • Artificial flavors and toxic substances used.

Policy Recommendations

  • Allow blended mustard oil sales in packaged and branded form with clear labelling.
  • Enforce blending limits (currently often breached).
  • Strengthen State-level food safety mechanisms (health is a State subject).
  • Prioritize development of low-erucic GM mustard varieties with <5% content.
  • Take a holistic view — blend health, economic, and scientific perspectives in policymaking.

Does the civil services examination need reform?


Historical Background

  • The structure of the civil services exam is rooted in the Macaulay Report of 1854 which emphasized merit-based selection.
  • The Kothari Committee (1975) formalized the three-tier structure: Prelims, Mains, and Interview.

Relevance : GS 2(Education )

Evolution of Preliminary Exam

  • Earlier format: Optional subject + General Studies with a 2:1 weightage.
  • Results were opaque; only names of qualifiers were published—no marks or cut-offs were revealed.
  • This ‘black box model limited aspirants’ ability to question results.

Transparency and Reform Pressure

  • Post-RTI Act (2005): UPSC had to disclose evaluation methods.
  • Growing scrutiny led to formation of the S.K. Khanna Committee (2010).
  • Major reform (2011): Optional paper removed. Prelims restructured to:
    • Paper I: GS
    • Paper II: CSAT (aptitude, reasoning, English)

Issues with CSAT (Paper-II)

  • Originally, CSAT marks were counted, favoring urban, English-medium, science/engineering students.
  • This triggered protests, particularly from rural/Humanities background aspirants.
  • Change made: CSAT became a qualifying paper (33% minimum), marks not counted for merit.

Main Exam Concerns

  • Restructured in 2013 after Nigvekar Committee recommendations.
  • GS papers now cover wide topics: polity, governance, economy, etc.
  • Current issues:
    • Short-answer focus (20 questions) encourages rote memorization over analysis.
    • No long-form questions that test deep analytical or problem-solving abilities.
    • Optional subject choices driven by scoring trends, not academic background—misaligns intent.

Prelims as a ‘Gatekeeper’

  • Prelims now functions more as a screening tool, cutting ~5 lakh applicants to ~10,000.
  • Paper-I (GS) is highly unpredictable, making preparation uncertain.
  • Paper-II still favors science/engineering students, even though it’s qualifying.
  • Opportunity cost is high for serious aspirants investing years into uncertain outcomes.

Suggested Reforms

  • Re-evaluate the role of Prelims: Ensure it tests potential, not just elimination.
  • Revamp GS Mains papers: Include long-form analytical questions.
  • Replace the optional subject with two papers on governance and public policy to ensure relevance.
  • Improve alignment between the exam structure and the qualities expected in civil servants.

Conclusion

  • The current system, though evolved, still reflects structural distortions.
  • A comprehensive reform is needed to:
    • Reduce unfair filtering,
    • Promote diversity,
    • Encourage analytical thinking over rote learning,
    • And better align aspirants’ capabilities with administrative roles.

No contempt if Parliament or legislatures make laws: SC


Background of the Case

  • Petitioners: Nandini Sundar (sociologist) and others filed a contempt petition (2012).
  • Target: Chhattisgarh government’s alleged non-compliance with the SC’s 2011 order.
  • The SC in 2011 had directed the State to disband vigilante groups (like Salwa Judum) and stop arming tribals as Special Police Officers (SPOs).

Relevance : GS 2(Polity , Judiciary)

Petitioners’ Allegations

  • The State bypassed the SC’s directions by:
    • Enacting Chhattisgarh Auxiliary Armed Police Force Act, 2011 — legalising SPOs.
    • Not vacating schools/ashrams occupied by security forces.
    • Failing to compensate victims affected by Salwa Judum and SPO actions.

Supreme Court’s Ruling (May 15, 2024)

  • Law made by legislature ≠ contempt of court.
  • Legislatures have plenary powers to make laws.
  • Unless a law is declared unconstitutional, it remains valid and cannot be equated with defiance of court orders.
  • Contempt plea dismissed.

Key Judicial Observations

  • Balance of powers must be maintained between judiciary and legislature.
  • A law passed post-court order is not contempt unless:
    • It directly disobeys the order.
    • It is declared ultra vires the Constitution.
  • Remedy against an unconstitutional law lies in challenging it in a constitutional court, not through contempt proceedings.

Broader Concerns & Directions

  • Recognised the prolonged unrest in Chhattisgarh due to Maoist violence.
  • Urged specificpeace and rehabilitation measures by:
    • State government
    • Union government
  • Cited Article 315: Responsibility lies with both governments to ensure law and order and welfare of residents.

Legal and Constitutional Significance

  • Reiterates legislative supremacy in its domain unless judicially struck down.
  • Clarifies that legislative action isn’t inherently contemptuous of earlier court orders.
  • Strengthens separation of powers and checks and balances in governance.

‘Sulphur-cleaning device in coal plants not necessary’


Context

  • FGD (Flue Gas Desulphurisation) units are used to reduce sulphur dioxide (SO) emissions from coal-fired thermal power plants (TPPs).
  • These were made mandatory in 2015 as part of stricter environmental norms.
  • Despite repeated extensions, 92% of Indias 600 units still haven’t installed FGDs.

Relevance : GS 3(Environment an dEcology)

Committee Recommendation

  • High-powered expert committee chaired by PSA Ajay Sood recommends FGDs are unnecessary for 80% of plants.
  • Suggests FGDs be mandatory only in Category A plants:
    • Within 10 km of NCR and cities with 1 million+ population.
    • Out of 66 such plants, only 14 have FGDs installed.

Scientific Rationale Behind the Recommendation

  • Ambient SO levels across India are between 10–20 µg/m³, well below the national standard of 80 µg/m³.
  • Indian coal is naturally low in sulphur content.
  • Cities with FGDs and without FGDs show negligible difference in ambient SO₂ levels.
  • SO₂ levels in general do not exceed permissible limits, hence do not justify nationwide FGD installation.

Operational & Economic Considerations

  • High capital costs and few vendors for FGD installation.
  • Potential rise in electricity tariffs if cost passed to consumers.
  • COVID-19 disruptions cited as a reason for delays in FGD compliance.
  • Historical deadline extensions by the Ministry of Power due to implementation hurdles.

Environmental Compliance

  • Committee clarifies:
    • TPPs must still meet standards for:
      • Particulate Matter (PM) emissions.
      • Freshwater consumption.
    • SO₂ stack emission limits can be relaxed, as long as National Ambient Air Quality (NAAQ) standards are met.
  • NAAQ standards, not stack norms, are the primary metric for protecting public health.

Institutions Involved

  • Reports considered from:
    • CSIR-NEERI
    • National Institute of Advanced Studies
    • IIT Delhi
  • All supported the view that FGDs are not essential across all plants.

Policy Implications

  • Marks a major reversal of India’s 2015 emission control policy.
  • Likely cost savings for power producers, but raises concerns over long-term air quality safeguards.
  • Reflects a shift towards region-specific environmental regulation rather than blanket norms.

EC introduces new tech-driven system to update voter turnout


Context

  • The Election Commission (EC) has introduced a technology-based system to provide real-time updates on voter turnout.
  • Comes amid opposition concerns over alleged discrepancies and delays in previous turnout data reporting.
  • To be implemented before the Bihar Assembly elections later this year.

Relevance : GS 2(Elections , Reforms)

Key Features of the New System

  • Presiding officers at each polling station will directly enter turnout data every two hours into the ECINET app.
  • Data is automatically aggregated at the constituency level.
  • Reduces dependence on manual reporting via calls, SMS, or WhatsApp.

Improvements Over Previous Method

  • Earlier method involved:
    • Manual recording by sector officers.
    • Delays of 4–5 hours, with some updates arriving next day.
  • New system aims for:
    • Near real-time updates every two hours.
    • Final turnout data entered at polling station itself before presiding officers leave.

Tech Implementation

  • Uses the ECINET app for data entry.
  • Becomes a core part of ECINET infrastructure.
  • The Voter Turnout App will reflect constituency-wise data updates.
  • Offline mode available; data syncs once network is restored.

 Advantages

  • Faster transparency, reducing data discrepancy allegations.
  • Greater accountability of presiding officers at the booth level.
  • Enhances public trust in the polling process.
  • Reduces manual errors and communication lags.

Challenges & Conditions

  • Network connectivity in rural or remote polling booths may delay real-time data.
  • Continued need for training of polling staff in app usage.
  • Approximate data still subject to minor post-poll adjustments.

 Broader Implications

  • Reinforces EC’s commitment to transparent, tech-driven elections.
  • Reflects the increasing role of digital infrastructure in electoral processes.
  • Sets precedent for future state and national elections.

Bacteria found at Rajgir hot spring lake shows antimicrobial activity


Scientific Background & Relevance

  • Thermophiles are bacteria that thrive in high temperatures (45–70°C), intolerable for most life forms.
  • Hot environments like hot springs, deep-sea vents, compost piles are rich in minerals but have fewer life competitors.
  • Thermophiles often produce potent antibiotics to outcompete other organisms in these harsh niches.

Relevance : GS 3(Environment and Ecology)

Study at Rajgir Hot Spring Lake (Nalanda, Bihar)

  • Conducted by Vellore Institute of Technology (VIT), Tamil Nadu.
  • Marked as one of India’s first microbiological investigations into the Rajgir hot spring.
  • Temperature of water and soil samples ranged between 43–45°C.

Key Findings

  • Used 16S rRNA metagenomics to analyze microbial diversity.
  • Found Actinobacteria dominated (40–43%) of the microbial population.
    • Significant since most hot springs globally have <20% Actinobacteria.
    • Known for producing important antibiotics (e.g., streptomycin, tetracycline).

Antibacterial Potential

  • Isolated seven strains of Actinobacteria that showed potent antibacterial activity.
  • Tested against pathogens like E. coli, Salmonella, Klebsiella, Pseudomonas, Staphylococcus.
  • Identified antibacterial activity by observing growth inhibition on culture plates.

Discovery of New Antimicrobial Compound

  • Diethyl phthalate extracted using Gas Chromatography-Mass Spectrometry (GC-MS).
  • Sourced from Actinomycetales bacterium spp.
  • Effective against Listeria monocytogenes, a deadly foodborne pathogen causing listeriosis.

Broader Implications

  • Urgent need for new antibiotics due to rising antimicrobial resistance (AMR).
  • WHO projects $1 trillion global healthcare cost by 2050 due to AMR.
  • Discovery at Rajgir highlights the untapped potential of Indian hot springs in antibiotic research.

Industrial & Agricultural Applications

  • Thermophiles also produce enzymes and compounds useful in:
    • PCR testing (e.g., enzyme from Thermus aquaticus used in COVID testing).
    • Agriculture: e.g., Leh hot springs’ bacteria shown to promote plant growth.

Challenges & Gaps

  • Indian hot springs are still understudied despite their potential.
  • Field sampling in extreme temperatures is logistically difficult.
  • Identifying active compounds from a microbial pool remains a time-intensive process.
