World Bank’s A Breath of Change: South Asia Air Pollution
Why in the news
A World Bank report warns that pollution in the IGP-HF region crosses borders and urges urgent regional cooperation.
About the report
- A strategic solutions document, not only a diagnosis.
- Covers 13 jurisdictions in 5 countries: India, Bangladesh, Nepal, Pakistan, Bhutan.
- Treats the region as a single airshed.
Key data
| Indicator | Finding |
|---|---|
| Premature deaths | About 1 million a year |
| Economic loss | About 10% of regional GDP yearly |
| Life expectancy | Over 3 years lost to PM₂.₅ |
| Children | 81% of public-school students exposed above 35 µg/m³ |
| PM₂.₅ level | 8-20 times WHO guidelines |
| Outside origin | Above 50% in many areas; about 68% in Nepal’s Terai |
Why pollution crosses borders
- Himalayan barrier traps pollutants; winter inversions worsen smog; Delhi receives inflow from Punjab and Haryana.
- North-westerly winter winds; Pakistan’s Punjab can supply up to 30% of PM₂.₅ in Indian Punjab.
- Precursor gases (SO₂, NOx, ammonia) form secondary PM₂.₅ far away.
- Post-harvest crop burning in India and Pakistan; industrial clusters and brick kilns.
Existing initiatives
- Kathmandu Roadmap (2022): science-policy dialogue.
- Thimphu Outcome (2024): ’35 by 35′, i.e. PM₂.₅ of 35 µg/m³ or less by 2035.
- Malé Declaration: non-binding monitoring platform.
- India’s NCAP (PM₁₀, 130+ cities); Surat’s PM Emissions Trading System.
Concerns
- Scattered mandates and weak Centre-State-local coordination.
- No long-term regional funding.
- Understaffed pollution boards; city-skewed monitoring.
- High upfront costs of clean equipment and retrofits.
Way forward: 4Is
| Pillar | Action |
|---|---|
| Information | Real-time monitoring; satellite data and GeoAI for hotspots |
| Incentives | Reform fuel and fertiliser subsidies towards EVs, clean cooking, Happy Seeder |
| Institutions | Clean Air Acts; permanent regional secretariat |
| Infrastructure | Regional grids, EV corridors, shared MSME boilers |
Emissions Trading Systems and pollution taxes such as Nepal’s Green Tax are also urged.
