Sonkach, a municipality in Madhya Pradesh, India, occupies a relatively flat terrain within the larger Malwa Plateau region. Situated at coordinates 22.9717°N, 76.3467°E, the town’s geography is defined by its position within the Narmada River basin, though not directly on the river itself. The surrounding landscape is predominantly agricultural, characterized by fertile black cotton soil supporting crops like cotton, wheat, and soybean. This agricultural intensity contributes to seasonal biomass burning, a significant local air quality factor. Sonkach’s elevation is modest, around 345 meters, influencing atmospheric dispersion. The urban-rural gradient is sharp; Sonkach serves as a market town for surrounding villages, meaning increased vehicular traffic during market days. While not a major industrial hub, small-scale brick kilns and stone crushing units operate in the vicinity, adding to particulate matter pollution. The town’s location experiences a distinct monsoon season, impacting dust levels and pollutant washout. The lack of substantial natural barriers to air flow means pollutants can accumulate during stable atmospheric conditions, and regional transport of pollutants from larger industrial areas to the west is also possible. Understanding this interplay of agricultural practices, localized industry, and regional climate is crucial for assessing Sonkach’s air quality.

Sonkach’s air quality follows a distinct seasonal pattern. The post-monsoon period, from October to November, often sees the poorest air quality. The cessation of monsoon rains coincides with increased agricultural burning to clear fields after harvest, releasing significant amounts of particulate matter. Cooler temperatures and calmer winds during these months exacerbate pollution, creating conditions for temperature inversions that trap pollutants near the ground. December to February brings relatively cleaner air, with cooler temperatures and occasional rainfall helping to disperse pollutants. However, domestic fuel burning for heating increases particulate matter. March to May is characterized by rising temperatures and dust storms, increasing coarse particulate matter concentrations. The pre-monsoon season, June, sees a gradual improvement as dust settles and winds pick up. The monsoon season, from July to September, generally offers the best air quality due to rainfall washing away pollutants. However, increased humidity can promote the formation of secondary pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during October-November and take precautions during dust storm periods. Monitoring wind patterns and avoiding peak burning times are advisable.
