Peduasi, nestled within Ghana’s Eastern Region, occupies a geographically significant position at approximately 5.8065° latitude and -0.1847° longitude. The city’s terrain is gently undulating, part of the larger Voltaian Plateau, characterized by lateritic soils and interspersed with pockets of forested areas. Its elevation, while modest, contributes to localized microclimates. Peduasi sits within a transitional zone, bordering both agricultural lands and the fringes of the forested Ashanti Region. This proximity to agricultural zones means seasonal burning practices, common during land preparation, can significantly influence local air quality. The surrounding landscape is predominantly rural, a mosaic of smallholder farms cultivating cocoa, plantains, and other staples, creating a gradual urban-rural gradient. While not directly adjacent to a major river, Peduasi benefits from rainfall patterns associated with the Gulf of Guinea, influencing humidity levels and atmospheric stability. The city’s relatively small size (population 18,701) currently limits extensive industrial development; however, its location along key transportation routes connecting Accra to the north increases the potential for future vehicular emissions. The prevailing winds generally flow from the southeast, carrying moisture and potentially pollutants from more industrialized areas further west. Topography plays a role, with valleys potentially trapping stagnant air and exacerbating localized pollution events, particularly during periods of reduced wind speed. The overall geographic setting presents a complex interplay of natural and anthropogenic factors impacting Peduasi’s air quality.

Peduasi’s tropical climate dictates a distinct wet and dry season cycle, profoundly influencing its air quality profile. The dry season, typically spanning from November to March, often witnesses a noticeable increase in particulate matter. This is largely attributable to agricultural practices; farmers frequently employ controlled burns to clear land for planting, releasing significant quantities of smoke and ash into the atmosphere. Reduced rainfall during this period also limits the natural cleansing effect of precipitation, allowing pollutants to persist. Temperature inversions, common during the cooler nights of the dry season, can trap pollutants near the ground, further degrading air quality. The wet season, from April to October, brings frequent rainfall and higher humidity, generally leading to improved air quality as pollutants are washed from the atmosphere. However, periods of intense rainfall can sometimes lead to increased fungal spores and mold, impacting respiratory health. Fog, particularly during the transitional months of March and October, can also trap pollutants, creating localized episodes of poor air quality. Outdoor activities are generally more favorable during the wet season, especially during periods of consistent rainfall. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during the dry season, particularly during periods of agricultural burning. Minimizing exposure to smoke and seeking shelter indoors during these times is advisable. Awareness campaigns educating farmers on alternative land clearing methods could significantly mitigate the seasonal pollution peaks.
