UPSC CSE Context
Why in News
A CSTEP study quantifies inter-state pollution contributions in South India, revealing Karnataka as the third-highest contributor.
Syllabus Connection
Environment and Ecology; Governance; Disaster Management
Exam Relevance
Useful for questions on air pollution governance, inter-state environmental issues, and policy mechanisms like NCAP.
Core Issue
South Indian states significantly contribute to each other's air pollution.
Key Development
CSTEP study shows 38-65% of pollution in each South Indian state originates from within the region.
Stakeholders
- Central Pollution Control Board
- South Indian state governments
- National Clean Air Programme
Static Knowledge
High-Value Background
- Air pollution travels across state boundaries, making regional coordination essential.
Exam Linkage
- Relevant for questions on airshed management and inter-state environmental governance.
Concepts in Context
- Airshed: a geographic area where air pollutants mix and affect common air quality.
- Non-attainment cities: urban areas failing to meet national ambient air quality standards.
Institutions and Mechanisms
- Commission for Air Quality Management in NCR is a model for regional air quality governance.
Dynamic Analysis
Environment and Ecology
- Transboundary pollution challenges state-centric air quality management.
- Meteorology and geography influence pollution transport, unlike the Indo-Gangetic Plain.
- Domestic, industrial, and open burning are major local sources.
- South India lacks a single pollution hotspot, complicating targeted interventions.
Governance
- Absence of a regional coordination body hampers effective airshed management.
- States have not notified approved fuel frameworks, delaying pollution control.
- Uniform targets for EV adoption and phasing out old vehicles are needed.
- NCAP funds can support regional action plans.
Federalism
- Inter-state pollution requires cooperative federalism for effective mitigation.
- Net contributors and receivers create asymmetric responsibilities.
- Central oversight may be necessary to resolve cross-border disputes.
Prelims Takeaways
- Karnataka contributes 47% of pollution to other South Indian states.
- 25 cities in South India are classified as non-attainment cities under NCAP.
Mains Value Addition
Arguments
- Regional airshed management is essential due to transboundary pollution flows.
- A dedicated South Indian air quality commission can harmonize state efforts.
- Uniform fuel and vehicle policies can reduce regional emissions.
Data Points
- Pollution contributions: Telangana 38%, Andhra Pradesh 44%, Karnataka 47%, Tamil Nadu 61%, Kerala 65%.
Counterpoints
- State autonomy may resist centralized air quality management.
- Economic costs of transitioning to cleaner fuels and EVs may burden poorer states.
Way Forward
- Establish a South Indian airshed management authority modeled on CAQM.
- Notify approved fuel frameworks across all five states.
- Utilize NCAP funds for regional air quality monitoring and mitigation.
