Ankalgi, nestled in the northern reaches of Karnataka, India, occupies a geographically significant position within the Belagavi district. Located at approximately 16.0333° N latitude and 74.7000° E longitude, the town’s terrain is characterized by gently undulating plains transitioning into the foothills of the Western Ghats to the west. This proximity to the Ghats influences local weather patterns and contributes to a unique microclimate. The surrounding landscape is predominantly agricultural, with extensive fields of sugarcane, maize, and pulses dominating the rural areas. Ankalgi sits within a gradual urban-rural gradient, experiencing a blend of agricultural practices and emerging urban development. While not directly adjacent to a major river, the town benefits from groundwater resources and occasional runoff from the Ghats during the monsoon season. The regional industrial landscape is relatively sparse, with smaller-scale manufacturing and processing units scattered throughout the district, primarily focused on agricultural produce. The elevation, averaging around 550 meters above sea level, plays a role in atmospheric stability, occasionally leading to temperature inversions, particularly during the cooler months. The town’s location, buffered by agricultural land and the Ghats, initially offered some natural air filtration, but increasing local traffic and limited industrial regulation pose growing challenges to air quality. The prevailing winds, generally southwesterly, carry moisture and pollutants from surrounding areas, impacting the town’s atmospheric composition.

Ankalgi’s air quality experiences a distinct seasonal cycle dictated by the region’s tropical climate. The monsoon season, typically spanning June to September, brings relief from accumulated pollutants as heavy rainfall washes particulate matter from the atmosphere and strong winds disperse emissions. However, increased agricultural burning during this period, particularly after the harvest, can temporarily elevate levels of smoke and carbon monoxide. The post-monsoon period (October-November) often sees a gradual increase in pollutants as the rains subside and agricultural activity intensifies. Temperature inversions, common during the cooler dry season (December-February), trap pollutants near the ground, leading to periods of stagnant air and potentially elevated concentrations. Fog, frequently occurring during these months, further exacerbates this issue by reducing atmospheric mixing. The pre-monsoon season (March-May) is generally the most challenging, with rising temperatures, decreasing rainfall, and increased construction activity contributing to higher levels of dust, particulate matter, and vehicle emissions. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the pre-monsoon and dry season months, limiting outdoor exertion and monitoring local air quality information. While the monsoon offers a respite, the agricultural burning necessitates awareness and mitigation strategies. Outdoor activities are generally more favourable during the monsoon and post-monsoon periods, though vigilance regarding agricultural smoke remains important.
