Bhawānīgarh, nestled in the fertile plains of Punjab, India (30.2700° N, 76.0400° E), occupies a geographically significant position within the Indo-Gangetic Plain. The city’s terrain is predominantly flat, characteristic of the region, with an average elevation of approximately 238 meters above sea level. This low-lying topography, while conducive to agriculture, contributes to air quality challenges. Bhawānīgarh is surrounded by a landscape dominated by intensive agricultural land, a patchwork of wheat, rice, and maize fields, which are frequently subjected to seasonal burning after harvest – a major source of particulate matter. The city’s proximity to the Ghaggar River, though providing a water source, doesn't significantly influence local air quality due to the prevailing wind patterns and the scale of agricultural activity. The urban–rural gradient around Bhawānīgarh is relatively sharp; the city transitions quickly into agricultural zones, meaning pollutants from agricultural practices readily impact the urban environment. Further afield, the broader Punjab region is interwoven with industrial belts, particularly those related to food processing and manufacturing, adding to the regional pollution burden. The flat terrain and lack of natural barriers exacerbate the accumulation of pollutants, especially during periods of stagnant air. The city’s location within a densely populated and agriculturally intensive region makes it particularly vulnerable to transboundary pollution and the impacts of regional meteorological patterns.

Bhawānīgarh’s air quality follows a distinct seasonal pattern heavily influenced by agricultural practices and meteorological conditions. The dry winter months (November to February) are typically the most challenging. Following the rice harvest, widespread stubble burning commences, releasing significant quantities of particulate matter and other pollutants into the atmosphere. Coupled with frequent fog events, a common feature of the Punjab winter, this creates a persistent layer of stagnant air, trapping pollutants close to the ground. Temperature inversions, where colder air is trapped beneath a layer of warmer air, further exacerbate this situation, preventing vertical mixing and concentrating pollutants. Spring (March-May) sees a gradual improvement as temperatures rise and winds increase, dispersing some of the accumulated pollutants. The monsoon season (June-September) brings relief, with rainfall washing away particulate matter and increased wind speeds aiding in ventilation. However, heavy rainfall can also lead to localised flooding and associated issues. The post-monsoon period (October) can experience a brief resurgence of moderate pollution as agricultural activity ramps up again before the winter burning season. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the winter months, limiting outdoor activity and using air purifiers when possible. During the peak burning season (November-January), even healthy individuals should consider wearing masks and avoiding strenuous outdoor exercise.
