DEEPAVALI AIR POLLUTION AND MONITORING CHALLENGES
TOPIC: (GS3) ENVIRONMENT: THE HINDU
An analysis of CPCB air-quality data revealed that nearly 70% of reporting monitoring stations recorded peak PM2.5 concentrations of at least 250 µg/m³ during Deepavali.
Key Findings of the Report
- Nationwide pollution: Of 551 reporting stations, 375 recorded hourly PM2.5 peaks of 250 µg/m³ or above, compared with 96 before Deepavali.
- Geographical spread: High pollution was observed in Delhi, Maharashtra, Uttar Pradesh, Rajasthan, Haryana, Madhya Pradesh, Gujarat and Andhra Pradesh.
- Monitoring gaps: Only 571 of CPCB’s 634 stations were operational during the festival.
- Example: In Tamil Nadu, only nine of 37 stations reported PM2.5 readings during the analysed hours.
Understanding PM2.5 Pollution
- PM2.5: Fine particulate matter measuring 2.5 micrometres or less in diameter.
- Sources: Firecrackers, vehicles, industries, construction dust and biomass burning.
- Health effects: Fine particles can enter deep into the lungs and bloodstream, increasing respiratory and cardiovascular risks.
- WHO guideline: The recommended 24-hour PM2.5 average is 15 µg/m³.
- Important distinction: The report’s 250 µg/m³ threshold refers to hourly peaks, not India’s official daily AQI classification.
Why Does Pollution Increase During Deepavali?
- Firecracker emissions: Release particulate matter, sulphur dioxide (SO₂) and other pollutants.
- Weather conditions: Low wind speeds and temperature inversions can trap pollutants near the ground.
- Existing pollution: Vehicle emissions, industrial activity and regional biomass burning worsen the cumulative burden.
- Green crackers: Their effectiveness depends on product standards, enforcement and actual emission reductions.
Air-Quality Monitoring Challenges
- Data interruptions: Several stations stopped reporting during periods of intense pollution.
- CPCB explanation: Some analysers have an upper measurement range of 1,000 µg/m³, potentially causing missing readings.
- Unresolved concern: Some stations stopped reporting even when their last recorded values were below that limit.
- Governance issue: Incomplete data can weaken pollution alerts, scientific assessment and public accountability.
Government Measures
- Air (Prevention and Control of Pollution) Act, 1981: Provides the legal framework for controlling air pollution.
- National Clean Air Programme (NCAP): Supports city-level action to reduce particulate pollution.
- GRAP: Introduces graded emergency measures during worsening air-quality episodes in Delhi-NCR.
- CAAQMS network: Enables continuous measurement of major air pollutants.
Way Forward
- Reliable monitoring: Upgrade sensors, strengthen maintenance and publicly explain data gaps.
- Emission control: Enforce firecracker standards and regulate transport, industrial and construction emissions.
- Regional coordination: Address pollution across State boundaries through joint action.
- Public health: Strengthen early warnings, hospital preparedness and protection for vulnerable groups.
- Long-term planning: Promote cleaner transport, energy efficiency and evidence-based urban management.
Conclusion
India needs year-round emission reduction and transparent pollution monitoring to ensure that festive celebrations do not come at the cost of public health.
OBC CREAMY LAYER AND PARENTAL INCOME
TOPIC: (GS2) POLITY: THE HINDU
On November 6, 2026, the Supreme Court reaffirmed its March 11 ruling that parental salary alone cannot determine OBC creamy layer status.
What is the OBC Creamy Layer?
- Meaning: The relatively advanced sections of Other Backward Classes (OBCs), excluded from reservation benefits.
- Objective: Ensure that reservation reaches socially and educationally disadvantaged communities.
- Constitutional basis: Articles 15(4), 15(5) and 16(4) enable affirmative action for eligible disadvantaged groups.
- Indra Sawhney v. Union of India (1992): Established the principle of excluding the creamy layer from OBC reservation.
What Did the 1993 Office Memorandum Provide?
- DoPT framework: Established criteria for identifying the creamy layer based on parental position, occupational status and income.
- Status-based exclusion: Certain senior government positions attract exclusion irrespective of salary fluctuations.
- Income/wealth test: Parental salary and agricultural income are excluded from the specified income calculation.
- Current ceiling: The income threshold was raised to ₹8 lakh annually in 2017; it is not a universal salary-based test.
Supreme Court’s March 11 Judgment
- Core ruling: Parents’ salary cannot independently justify denying an OBC Non-Creamy Layer (NCL) certificate.
- Relevant factors: Employment category, rank and equivalence of posts must also be examined.
- PSU employees: Their children cannot be excluded merely because parental salaries exceed the income threshold.
- 2004 clarification: Cannot introduce conditions inconsistent with the original 1993 framework.
November 6 Clarification
- No blanket retrospective reopening: Completed appointments, promotions, admissions and service allocations remain undisturbed.
- Pending disputes: Courts and authorities may examine unresolved claims using the March judgment’s principles.
- Future selections: Decisions made after March 11 must follow the correctly interpreted creamy-layer framework.
- Implementation: The Court extended compliance time by two months.
Impact on Civil Services Examination 2025
- Results: Declared on March 6, 2026, before the March judgment.
- Service allocation: Not finalised when the ruling was delivered.
- Consequence: Eligible OBC candidates must receive consideration under the clarified criteria.
- Administrative responsibility: The government must ensure lawful assessment without unnecessarily disturbing settled selections.
Significance and Way Forward
- Social justice: Prevents wrongful exclusion of eligible OBC candidates.
- Equality: Promotes consistent treatment of government and PSU employees’ children.
- Administrative clarity: Establish transparent equivalence between posts across organisations.
- Reforms: Standardise NCL verification, publish clear guidelines and establish time-bound grievance mechanisms.
Conclusion
Creamy layer exclusion must reflect genuine social advancement rather than salary alone, ensuring that reservation remains fair, consistent and constitutionally meaningful.
