Delhi experiences a seasonal decline in air quality, typically commencing in October. Recent research from IIT Kanpur characterizes the Delhi-NCR region's air as an interconnected atmospheric system encompassing 35 districts across Delhi, Haryana, Uttar Pradesh, and Rajasthan. This research indicates that crop-residue fires are episodic contributors but are not identified as the primary driver of the region's air quality issues; instead, the broader Delhi-NCR airshed is largely responsible. The article notes Delhi's current ratio of 0.2 electric buses per 1,000 people, suggesting that an increase to one electric bus per 1,000 could significantly reduce private vehicle dependence. Referencing global experiences, the piece highlights how sustained, science-led coordination—including energy transition, mobility reform, and air quality monitoring—has led to substantial reductions in pollution elsewhere. It proposes that improved air quality in Delhi could be achieved through a coordinated approach involving scientific insights, policy implementation, and community participation.
