Ville Bonheur, nestled in the Centre department of Haiti (coordinates 18.8160, -72.2019), presents a unique geographic profile significantly influencing its air quality. The city’s location is characterized by a gently sloping terrain, transitioning from the relatively flat coastal plain towards the foothills of the Massif de la Hotte, a significant mountain range. This proximity to the mountains creates a localized valley effect, potentially trapping pollutants under certain meteorological conditions. The surrounding landscape is a mosaic of small-scale agriculture – primarily sugarcane and fruit cultivation – interspersed with patches of remnant dry forest. This agricultural activity, while vital to the local economy, contributes to particulate matter emissions, particularly during harvest seasons when burning is sometimes practiced. The urban–rural gradient around Ville Bonheur is gradual, with small villages and agricultural plots blending seamlessly into the city’s periphery. While not directly adjacent to a major river, the city benefits from seasonal rainfall, which can help to cleanse the atmosphere, but also contributes to humidity and fog formation, impacting pollutant dispersion. There are no major industrial belts immediately surrounding Ville Bonheur; however, the city serves as a regional market town, experiencing increased vehicular traffic and associated emissions. The elevation, averaging around 150 meters above sea level, influences temperature patterns and atmospheric stability, impacting the vertical mixing of air pollutants. The prevailing trade winds, though generally beneficial for dispersion, can be interrupted by local topography, leading to localized air quality challenges.

Ville Bonheur’s tropical climate dictates a wet and dry season cycle, profoundly impacting its air quality. The dry season, typically spanning from December to April, often sees a slight improvement in air quality due to reduced rainfall and less agricultural burning. However, this period can also experience periods of stagnant air, particularly during temperature inversions, where a layer of warm air traps cooler air and pollutants near the ground. The months of January and February are often the most susceptible to these inversions, leading to a noticeable increase in particulate matter. The wet season, from May to November, brings frequent rainfall, which naturally washes pollutants from the atmosphere. However, intense rainfall events can also lead to increased dust and soil erosion, temporarily degrading air quality. Humidity levels are consistently high throughout the year, which can exacerbate respiratory issues. Fog, common during the transition periods between seasons, further restricts pollutant dispersion. During the harvest season (typically October-November), agricultural burning, though often informal and localized, can significantly elevate particulate matter concentrations. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during periods of stagnant air and increased agricultural activity. Outdoor activities are generally more favourable during the wetter months, but vigilance is still required, particularly during periods of heavy rainfall and subsequent dust plumes. The interplay of these seasonal factors creates a dynamic air quality profile for Ville Bonheur.
