Pudu, a small town in Karnataka, India, situated at coordinates 12.8667°N, 74.9673°E, occupies a relatively low-lying position within the coastal plain of the state. With a population of approximately 16,406, Pudu’s geography is defined by its proximity to the Arabian Sea, though it isn’t directly on the coast. The surrounding landscape is characterised by lush, agrarian fields – primarily paddy cultivation and coconut groves – interspersed with small pockets of cashew plantations. The terrain is generally flat, gradually rising as one moves inland towards the Western Ghats. This flat topography can contribute to the trapping of pollutants, particularly during periods of calm weather. Pudu’s location within a predominantly agricultural zone means that seasonal burning of crop residue is a significant factor influencing local air quality. The urban-rural gradient is quite sharp; Pudu itself is a concentrated settlement, but quickly gives way to rural farmland. While not a major industrial hub, the presence of small-scale brick kilns and rice mills in the surrounding areas contributes to particulate matter emissions. The coastal climate brings high humidity for much of the year, influencing pollutant dispersion. Understanding this interplay of geography and activity is crucial for assessing Pudu’s air quality challenges.

Pudu’s air quality follows a distinct seasonal pattern dictated by the monsoon and agricultural cycles. The pre-monsoon months of March to May typically see a deterioration in air quality. Rising temperatures and dry conditions encourage farmers to clear fields through burning, releasing significant amounts of smoke and particulate matter. This period is often accompanied by dust storms, further exacerbating the issue. The southwest monsoon, arriving in June and lasting until September, brings relief through rainfall which washes away pollutants, generally resulting in cleaner air. However, increased humidity can also promote the formation of mould spores, impacting respiratory health. October and November witness a transition period, with decreasing rainfall and a build-up of pollutants from post-harvest burning. The winter months, December to February, are characterised by cooler temperatures and calmer winds, leading to temperature inversions that trap pollutants near the ground. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during March-May and December-February. Monitoring wind patterns and avoiding peak burning times are crucial for mitigating exposure.
