Morafeno, a small city nestled within the Boeny region of Madagascar, presents a unique geographic context influencing its air quality. Located at approximately -15.4902° latitude and 48.2067° longitude, the city sits inland from the Mozambique Channel, roughly 150km east of Mahajanga, the regional capital. The terrain is predominantly flat to gently undulating, characteristic of the Marovoay plain, a vast agricultural zone dedicated primarily to rice cultivation and, increasingly, sugarcane. This surrounding agricultural landscape is a significant factor; seasonal burning of agricultural residue contributes substantially to particulate matter pollution. Morafeno’s elevation is low, averaging around 30 meters above sea level, which limits natural dispersion of pollutants. The urban-rural gradient is relatively sharp, transitioning quickly from densely populated residential areas to expansive farmland. While Morafeno itself lacks heavy industry, the proximity to larger agricultural processing facilities in the region, and the transport networks serving them, introduces localised emissions. The prevailing winds, influenced by the southeast trade winds, can carry pollutants from these sources into the city, particularly during the dry season. The lack of significant natural barriers, like hills or forests, further exacerbates this effect, making Morafeno vulnerable to regional air quality fluctuations.

Morafeno experiences a distinct wet and dry season, profoundly impacting air quality. The wet season, roughly November to April, brings relief from particulate matter pollution. Frequent rainfall effectively washes pollutants from the atmosphere, and increased humidity suppresses dust. However, this period also sees increased fungal spores and potential for damp-related respiratory issues. May to October constitutes the dry season, and this is when air quality deteriorates significantly. Agricultural burning, preparing fields for the next planting cycle, becomes rampant, releasing large quantities of smoke and particulate matter. The dry winds exacerbate the problem, carrying smoke across the city. Temperature inversions, common during the cooler nights of the dry season, trap pollutants near ground level, worsening conditions. October is typically the worst month for air quality due to peak burning activity. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit outdoor exertion during this period. Conversely, the wetter months, particularly February and March, offer the best conditions for outdoor activities. Monitoring local fire reports and wind direction can provide short-term warnings of pollution spikes, even during the wet season.
