Begampur, a small urban centre in the Murshidabad district of West Bengal, India, sits at coordinates 22.3705°N, 88.4940°E. The city’s geography is defined by its location within the Ganges Delta, a low-lying, fertile alluvial plain. The terrain is predominantly flat, typical of deltaic regions, with a gentle slope towards the Bhagirathi River, a major distributary of the Ganges, which flows nearby. This proximity to the river influences local humidity and can contribute to fog formation during cooler months. Begampur is surrounded by intensely cultivated agricultural land, primarily rice paddies, and smaller pockets of jute cultivation, a characteristic feature of West Bengal’s agricultural landscape. While not a major industrial hub itself, Begampur’s regional position places it within reach of industrial activity concentrated further south towards Kolkata and in the more developed districts of West Bengal. The urban-rural gradient is sharp; the city is a relatively small settlement embedded within a largely rural backdrop. This close interaction between agricultural practices – including seasonal crop burning – and a growing urban population creates specific air quality challenges. The flat terrain also limits natural dispersion of pollutants, exacerbating localised pollution episodes. The deltaic environment means the city is also vulnerable to seasonal flooding, which can mobilise pollutants and impact air quality indirectly.

Begampur experiences a tropical climate with distinct wet and dry seasons, heavily influencing its air quality. The post-monsoon season (October-November) often sees a peak in pollution. The receding monsoon leaves behind stagnant air and cooler temperatures, fostering temperature inversions that trap pollutants near the ground. This coincides with increased agricultural burning as farmers clear fields after the harvest. Winter (December-February) brings drier conditions and frequent fog, further reducing dispersion and concentrating particulate matter. This is a period to avoid strenuous outdoor activity, particularly for those with respiratory conditions. The pre-monsoon season (March-May) sees rising temperatures and dust storms, elevating particulate matter levels. The onset of the monsoon (June-September) generally brings a significant improvement in air quality. Heavy rainfall effectively washes away pollutants, and increased humidity suppresses dust. However, increased moisture can also promote the growth of mould, potentially impacting those with allergies. While the monsoon offers relief, localised flooding can redistribute pollutants. Sensitive groups – children, the elderly, and those with pre-existing respiratory or cardiovascular conditions – should remain vigilant throughout the year, but particularly during the post-monsoon and pre-monsoon periods, and consider using air purifiers indoors.
