Chik Bānavar, nestled in the Shimoga district of Karnataka, India, occupies a geographically significant position within the Western Ghats foothills. Located at approximately 13.0846° N latitude and 77.5014° E longitude, the town’s elevation, around 850 meters above sea level, contributes to a relatively cool and pleasant climate compared to lower-lying regions of Karnataka. The surrounding landscape is dominated by undulating hills covered in dense deciduous forests, characteristic of the Malnad region. This proximity to forested areas, while aesthetically pleasing, can occasionally contribute to particulate matter from biomass burning during drier periods. Chik Bānavar sits within a transitional zone, exhibiting a gradual urban–rural gradient. While the town itself maintains a relatively small population of around 14,409, it serves as a local commercial hub for surrounding agricultural villages. The primary agricultural activities in the region include coffee, areca nut, and paddy cultivation. These agricultural practices, particularly the use of fertilizers and occasional burning of crop residue, can influence local air quality. The town's location away from major industrial belts mitigates the impact of heavy industrial pollution, however, the increasing use of personal vehicles and smaller-scale businesses within Chik Bānavar itself contributes to localized emissions. The terrain, with its slopes and valleys, can also influence air circulation patterns, potentially trapping pollutants in certain areas under specific meteorological conditions. The absence of major rivers directly adjacent to the town limits the impact of aquatic aerosols, but humidity levels are generally moderate.

Chik Bānavar’s air quality experiences a distinct seasonal cycle dictated by the region’s tropical monsoon climate. The monsoon season, typically spanning June to September, brings relief from accumulated pollutants due to frequent rainfall and strong winds that effectively disperse airborne particles. Humidity levels are high during this period, which can slightly reduce the impact of particulate matter on respiratory health. Conversely, the pre-monsoon months (March-May) often witness a deterioration in air quality. Rising temperatures and decreasing rainfall lead to stagnant air conditions, increasing the likelihood of temperature inversions, where cooler air is trapped beneath a layer of warmer air, preventing vertical mixing and concentrating pollutants near the ground. Agricultural burning, a common practice to clear fields for the next planting season, significantly contributes to particulate matter during this period. The post-monsoon season (October-November) sees a gradual improvement as rainfall decreases and winds pick up, but residual agricultural smoke can still be a factor. Winter months (December-February) are generally characterized by cooler temperatures and occasional fog, which can trap pollutants and reduce visibility. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during the pre-monsoon and winter months, limiting prolonged outdoor exposure and avoiding strenuous activities when air quality is visibly impacted. Maintaining indoor air quality through ventilation and air purification can also be beneficial during these periods.
