Kadavūr, nestled within the verdant landscape of Kerala, India, occupies a relatively low-lying position at approximately 9.3436°N, 76.5347°E. The city’s geography is defined by the undulating terrain typical of the state’s midlands, a transition zone between the Western Ghats and the Arabian Sea. This location, within the Kollam district, places Kadavūr amidst a rich agricultural belt, primarily focused on coconut, cashew, and spices. The surrounding landscape is characterised by dense vegetation, paddy fields, and a network of small rivers and canals that drain towards the Arabian Sea, roughly 20km to the west. While not directly on the coast, the proximity to the sea influences humidity levels and contributes to the region’s tropical climate. Kadavūr isn’t a major industrial hub, but smaller-scale processing of agricultural products and local brick kilns contribute to localised emissions. The urban-rural gradient is pronounced; Kadavūr itself is a relatively small town, surrounded by more dispersed rural settlements. This impacts air quality as agricultural practices, including seasonal burning of crop residue, can contribute to particulate matter, while limited vehicular traffic within the town itself keeps emissions relatively contained compared to larger cities. The terrain’s gentle slopes can also trap pollutants during periods of calm weather.

Kadavūr experiences a distinct tropical climate, with air quality fluctuating significantly between the wet and dry seasons. The southwest monsoon, typically arriving in June and lasting until September, brings heavy rainfall that effectively washes pollutants from the atmosphere, resulting in generally improved air quality during these months. However, increased humidity can also foster mould growth, impacting respiratory health. October to February constitutes the drier season, marked by lower rainfall and calmer winds. This period often sees a build-up of particulate matter from agricultural activities like harvesting and processing, alongside emissions from local brick kilns. Temperature inversions, common during cooler mornings in these months, can trap pollutants near ground level, exacerbating air quality issues. March to May, the hottest period, sees increased dust and potential for localised fires, further degrading air quality. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during the dry season, particularly March-May. Monitoring wind patterns is crucial; easterly winds can carry pollutants from inland areas, while westerly breezes offer some relief. Avoiding peak hours near agricultural processing areas is also advisable.
