Mpraeso, nestled within Ghana’s Eastern Region at coordinates 6.5932, -0.7346, is a town characterized by its hilly terrain and strategic position within the Kwahu Plateau. This elevated location, reaching approximately 300-400 meters above sea level, significantly influences local weather patterns and, consequently, air quality. The surrounding landscape is a mosaic of lush tropical rainforest, interspersed with agricultural lands primarily dedicated to cocoa, food crops, and increasingly, plantain cultivation. Unlike coastal Ghanaian cities, Mpraeso benefits from relatively good natural ventilation due to its altitude and the absence of significant industrial activity within the immediate vicinity. However, the town’s position downwind from larger agricultural areas means it can experience episodes of airborne particulate matter from agricultural burning, particularly during land preparation for planting. The urban-rural gradient is quite sharp; Mpraeso itself is a relatively small settlement, quickly transitioning to rural farmland and forested areas. The lack of major roadways passing *through* the town limits direct traffic pollution, but the increasing use of motorcycles and smaller vehicles contributes to localised emissions. The terrain channels winds, creating localized areas of pollutant concentration, especially in valleys and depressions.

Mpraeso experiences a distinct tropical climate with two primary seasons: a wet season (roughly April to October) and a dry season (November to March). Air quality generally improves during the wet season as rainfall effectively washes away particulate matter and suppresses dust. However, high humidity can also promote the formation of mold spores, potentially impacting respiratory health. Pollution peaks during the dry season, particularly in February and March, coinciding with the harmattan winds which carry Saharan dust southward. These dust events significantly elevate PM10 and PM2.5 levels. Agricultural burning, common during land preparation for the cocoa season, also contributes to increased particulate matter during the transition from wet to dry seasons (October-November). Temperature inversions, though less frequent than in temperate climates, can occur during the cooler nights of the dry season, trapping pollutants near the ground. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit strenuous outdoor activity during harmattan periods and periods of agricultural burning. The months of May to September generally offer the most favourable air quality conditions for outdoor activities.
