Mangalāpuram, nestled in the southern Indian state of Tamil Nadu (coordinates 11.5667° N, 78.3788° E), presents a fascinating case study in urban geography and air quality challenges. Situated within a predominantly rural landscape, the city’s population of 13,337 reflects a relatively small urban centre transitioning from an agrarian economy. The surrounding terrain is characterized by gently undulating plains, typical of the Kaveri delta region, with fertile agricultural lands dominating the immediate vicinity. This proximity to intensive farming practices, particularly rice cultivation, contributes to seasonal biomass burning, a significant factor in local air pollution. Mangalāpuram’s elevation is low, approximately 25 meters above sea level, which can exacerbate the trapping of pollutants, especially during periods of atmospheric stability. While not directly adjacent to a major river, the region is heavily influenced by the Kaveri River system, providing irrigation and impacting local humidity levels. The urban–rural gradient is gradual, with small villages and agricultural fields seamlessly blending into the city’s periphery. Further afield, industrial zones concentrated around Coimbatore, roughly 150km northwest, can contribute to regional pollution transport. The prevailing winds, generally southwesterly, can carry pollutants from these industrial areas towards Mangalāpuram, particularly during drier periods. The city’s compact urban form, with a mix of traditional dwellings and newer constructions, influences local wind patterns and ventilation, impacting the dispersion of pollutants emitted from residential and commercial activities.

Mangalāpuram’s tropical climate dictates a distinct wet and dry season cycle, profoundly influencing its air quality. The dry season, typically spanning from March to May, is characterized by high temperatures, low humidity, and reduced rainfall. This period often witnesses a peak in air pollution due to increased biomass burning from agricultural residue management – farmers clearing fields after the harvest. The lack of rainfall and lower humidity contribute to the persistence of particulate matter in the atmosphere. Temperature inversions, common during these months, trap pollutants near the ground, further worsening air quality. Conversely, the monsoon season (June to October) brings relief through frequent rainfall, which naturally cleanses the atmosphere by scavenging pollutants. Strong winds associated with the monsoon also help disperse pollutants, leading to improved air quality. November and February represent transitional periods, with cooler temperatures and occasional fog, which can temporarily reduce visibility and trap pollutants, creating localized air quality concerns. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, limiting outdoor activities during peak pollution hours, typically in the morning and late afternoon. Maintaining indoor air quality through ventilation and air purifiers is also advisable. During the monsoon, while overall air quality improves, heavy rainfall can lead to waterborne illnesses, highlighting the importance of safe water practices.
