Jāwalgeri, nestled in the northern reaches of Karnataka, India, occupies a geographically significant position within the larger Belagavi district. Located at approximately 15.8656° N, 76.8156° E, the town’s terrain is characterized by gently undulating hills and plains, typical of the Deccan Plateau. Its elevation, around 580 meters (1903 feet) above sea level, contributes to a relatively moderate climate, but also influences local air circulation patterns. The surrounding landscape is a mosaic of agricultural fields – predominantly sugarcane, maize, and pulses – interspersed with pockets of dry deciduous forest. This agricultural activity, while vital to the regional economy, can contribute to seasonal particulate matter pollution, particularly during harvest periods when burning of crop residue is practiced. Jāwalgeri’s proximity to the larger urban center of Belagavi (roughly 30 km) means it experiences a degree of urban influence, including vehicular emissions and potential industrial fallout. The urban–rural gradient is gradual, with smaller villages and agricultural lands dominating the immediate periphery. The Ghataprabha River flows nearby, offering a degree of moisture and influencing local humidity, but its impact on air quality is generally limited. Prevailing winds typically originate from the west, carrying air masses from the Arabian Sea, which can sometimes introduce moisture and influence pollutant dispersion. The region's geology, composed primarily of basaltic rock, also affects the composition of dust particles suspended in the air, potentially impacting respiratory health.

Jāwalgeri’s air quality follows a distinct seasonal pattern dictated by the region’s tropical climate and monsoon cycles. The dry season, spanning roughly from March to May, often witnesses a noticeable increase in particulate matter. This is largely attributable to increased dust generation from agricultural activities, coupled with stagnant air conditions resulting from temperature inversions – where a layer of warm air traps cooler air near the ground, inhibiting vertical mixing. The intense heat also exacerbates ozone formation. Conversely, the southwest monsoon (June to September) brings significant relief, as frequent rainfall effectively washes pollutants from the atmosphere and strong winds disperse any remaining contaminants. October and November represent a transitional period, with decreasing rainfall and a gradual return of drier conditions, potentially leading to a renewed rise in pollution levels. Winter months (December to February) are generally characterized by cooler temperatures and occasional fog, which can trap pollutants near the ground, particularly in the early morning hours. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during the dry season and periods of fog, limiting outdoor exertion and monitoring for any respiratory discomfort. Agricultural workers should be particularly mindful of dust exposure during harvest. Maintaining indoor air quality through ventilation and air purification can also provide some protection during periods of elevated pollution.
