Badarpur, nestled in the Cachar district of Assam, India, occupies a geographically significant position in the Barak Valley. Located at coordinates 24.8685°N, 92.5961°E, the town sits at a relatively low elevation, contributing to potential air stagnation. The surrounding landscape is characterised by lush, rolling hills transitioning into the plains of Bangladesh, a mere few kilometers to the south. The Barak River, a major tributary of the Meghna, flows nearby, influencing local humidity and potentially trapping pollutants during temperature inversions. Badarpur’s urban character is that of a developing town, serving as a commercial hub for the surrounding agricultural areas, primarily tea plantations and paddy fields. While not a major industrial centre itself, its proximity to industrial activity in nearby Silchar and the broader Cachar region contributes to regional pollution sources. The urban-rural gradient is pronounced, with a rapid shift from densely populated town centres to agricultural land. This proximity to agricultural practices introduces seasonal biomass burning, a significant contributor to particulate matter. The valley’s topography, partially enclosed by hills, limits air circulation, exacerbating pollution episodes, particularly during calmer weather conditions. This geographical setting dictates the specific challenges faced in maintaining good air quality in Badarpur.

Badarpur’s air quality follows a distinct seasonal pattern dictated by Assam’s tropical monsoon climate. The pre-monsoon months of March to May see a build-up of pollutants, driven by rising temperatures and drier conditions. Agricultural burning to prepare fields for the monsoon season significantly elevates particulate matter levels, making these months particularly challenging for those with respiratory sensitivities. The arrival of the monsoon in June brings temporary relief, as rainfall washes away pollutants and increased humidity suppresses dust. However, the monsoon also introduces dampness, fostering mould growth which can exacerbate respiratory issues. Post-monsoon, from September to November, sees a gradual deterioration in air quality as temperatures cool and wind speeds decrease, leading to increased pollutant concentration. This period is often marked by shallow temperature inversions, trapping pollutants near the ground. December to February are the coolest, driest months, often experiencing fog and stagnant air, leading to the highest pollution levels. Sensitive groups – children, the elderly, and those with pre-existing respiratory or cardiovascular conditions – should limit outdoor activity during March-May and December-February. Monitoring local weather patterns and avoiding peak pollution times is crucial for protecting health.
