Nanjangūd, nestled in the southern Indian state of Karnataka, occupies a geographically significant position within the Mysore district. Located at coordinates 12.1200°N, 76.6800°E, the city sits on the banks of the Kapila River, a tributary of the Kaveri. The terrain is generally flat, characteristic of the Deccan Plateau, with a gentle slope towards the river. Elevation averages around 768 meters (2,520 feet), influencing temperature and air circulation patterns. Nanjangūd’s urban character is a blend of historical significance – it was a prominent town under various dynasties – and modern development, though it retains a strong agricultural base. Surrounding the city are extensive agricultural lands, primarily sugarcane and rice paddies, alongside pockets of sandalwood forests, for which the region is renowned. The proximity to Mysore, a major industrial and tourism hub, introduces regional pollution transport. The urban-rural gradient is relatively sharp, with a noticeable increase in vehicular traffic and localized industrial activity within the city limits. This combination of factors – riverine influence, agricultural practices, regional industrial emissions, and the plateau’s topography – creates a unique set of conditions impacting Nanjangūd’s air quality, making it susceptible to both local and transported pollutants. The Kapila River, while providing a water source, can also contribute to humidity and potentially trap pollutants during temperature inversions.

Nanjangūd experiences a tropical climate with distinct wet and dry seasons, heavily influencing air quality. The post-monsoon period, from October to December, often sees a temporary improvement as rainfall washes away accumulated pollutants. However, this is followed by the dry season (January to May), when air quality typically deteriorates. Lower wind speeds and increased temperatures during these months promote the build-up of particulate matter from agricultural activities like sugarcane harvesting and burning, as well as dust from unpaved roads. February and March are often the most challenging months. The southwest monsoon, arriving in June and lasting until September, brings significant rainfall, effectively cleansing the air, but also increasing humidity which can foster mold growth indoors. During the monsoon, while particulate matter decreases, localized flooding can stir up sediment and contribute to microbial pollutants. Temperature inversions, common during the cooler months, exacerbate pollution by trapping emissions near ground level. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the dry season, particularly February-March. Monitoring weather patterns and avoiding peak traffic hours are advisable. The monsoon offers the most favourable conditions for outdoor activity, though precautions regarding waterborne diseases are necessary.
