Sanghera, a small city nestled within the fertile plains of Punjab, India, occupies a geographically significant position at 30.3986°N, 75.5614°E. The surrounding landscape is predominantly flat, characteristic of the Indo-Gangetic Plain, with a gentle slope towards the southwest. This flatness contributes to limited natural air dispersion. The city’s elevation is relatively low, around 230 meters above sea level, further reducing the potential for atmospheric mixing. Sanghera benefits from proximity to several smaller tributaries of the Sutlej River, influencing local humidity and occasionally trapping pollutants during temperature inversions. The region is intensely agricultural, dominated by wheat and rice cultivation, practices that contribute to seasonal biomass burning. While Sanghera itself isn’t a major industrial hub, its location within Punjab places it downwind of larger industrial areas like Ludhiana and Jalandhar, receiving transported pollutants. The urban-rural gradient is relatively sharp; the city is a concentrated pocket within a vast agricultural matrix. This proximity means pollutants from agricultural practices, such as stubble burning after the rice harvest, directly impact Sanghera’s air quality. The lack of significant topographical features hinders the flushing out of these pollutants, creating conditions conducive to air stagnation and elevated pollution levels.

Sanghera’s air quality follows a distinct seasonal pattern. The post-monsoon period, October and November, represents the most challenging time, coinciding with widespread agricultural stubble burning. Calm winds and temperature inversions trap smoke and particulate matter, leading to significantly degraded air. December and January bring cooler temperatures and often dense fog, exacerbating pollution by limiting dispersion. While winter sees reduced agricultural activity, residential heating using biomass fuels adds to the particulate load. February and March offer a gradual improvement as temperatures rise and wind speeds increase, though dust storms can temporarily elevate particulate matter. The monsoon season, from July to September, generally provides the cleanest air. Heavy rainfall effectively washes pollutants from the atmosphere, and increased humidity suppresses dust. However, stagnant conditions immediately before and after monsoon rains can lead to localised pollution build-up. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during October-January. Avoiding peak hours and wearing masks are advisable. The monsoon months offer the most favourable conditions for outdoor exercise and recreation. Monitoring local conditions is crucial, as even during cleaner periods, episodic pollution events can occur.
