Kawa, nestled within the Bago Region of Myanmar (coordinates 17.0897° N, 96.4663° E), occupies a geographically significant position within the Irrawaddy River basin. The town’s setting is characterized by a gently undulating terrain, transitioning from the fertile plains surrounding the Irrawaddy to the foothills of the Bago Yoma range to the east. This proximity to the Bago Yoma, a range of low mountains, influences local weather patterns and can contribute to localized air quality challenges. Kawa itself is situated relatively close to the river, providing a degree of humidity and moderating temperatures, but also potentially exposing the town to pollutants transported along the waterway. The surrounding landscape is predominantly agricultural, with rice paddies and other crops dominating the rural areas. This agricultural activity, while vital to the regional economy, can contribute to seasonal particulate matter pollution, particularly during burning seasons. The urban–rural gradient around Kawa is gradual; the town represents a small but important hub within a largely agrarian landscape. There are no major industrial belts immediately adjacent to Kawa, but the broader Bago Region does contain some light industrial activity, and transport corridors connecting Kawa to larger urban centers like Yangon could introduce external pollutants. The elevation of Kawa is relatively low, around 15 meters above sea level, which can exacerbate the trapping of pollutants under certain meteorological conditions, especially during periods of temperature inversion.

Kawa’s air quality experiences a distinct seasonal cycle dictated by Myanmar’s monsoon climate. The wet season, typically spanning from May to October, generally brings improved air quality due to frequent rainfall which naturally scrubs pollutants from the atmosphere. High humidity also reduces the concentration of particulate matter. However, periods of prolonged rainfall can lead to stagnant water and associated issues. The dry season, from November to April, presents a more complex picture. While temperatures are generally more comfortable, the lack of rainfall and increased sunshine can lead to a build-up of pollutants. Agricultural burning, a common practice for land clearing and crop residue disposal, significantly contributes to particulate matter pollution during this period, particularly in February and March. Temperature inversions, where a layer of warm air traps cooler air near the ground, are also more frequent during the dry season, further exacerbating pollution. Fog, common in the early morning during the cooler months, can also trap pollutants close to the ground. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly on days with visible haze or fog. Outdoor activities are generally more favorable during the wet season, although heavy rainfall can limit visibility and create other hazards. The transition months of April and October represent periods of fluctuating air quality, influenced by the shifting monsoon patterns.
