Mahabo, situated in the Toliara region of southern Madagascar, presents a unique geographic context influencing its air quality. Located at -20.3807 latitude and 44.6654 longitude, the city lies relatively close to the Mozambique Channel, approximately 25 kilometers inland. The terrain is characterised by a gently undulating coastal plain, transitioning into spiny forest further inland. This proximity to the ocean introduces a constant supply of moisture and salt spray, impacting local atmospheric conditions. Mahabo’s elevation is low, averaging around 30 meters above sea level, which limits natural dispersion of pollutants. The surrounding landscape is dominated by dry deciduous forests and scrubland, interspersed with areas of traditional *ve-ve* agriculture – small-scale, intensive farming often involving slash-and-burn techniques. This agricultural practice, particularly during land preparation, contributes to seasonal particulate matter pollution. The urban-rural gradient is relatively sharp; Mahabo itself is a small urban centre surrounded by sparsely populated rural areas. Limited industrial activity is present, but charcoal production for cooking and heating is widespread, representing a significant localised source of emissions. Dust from unpaved roads and construction further degrades air quality, particularly during the dry season. The prevailing winds, influenced by the Indian Ocean monsoon system, play a crucial role in pollutant transport and dispersion.

Mahabo experiences a distinct wet and dry season, profoundly impacting air quality. The dry season, from April to November, is characterised by consistently high temperatures and minimal rainfall. This period sees a peak in particulate matter pollution, driven by increased dust from unpaved roads, agricultural burning for land preparation, and charcoal production. Strong winds during this time can exacerbate dust storms, transporting particles across the city. November to March constitutes the wet season, bringing relief from dust and a temporary improvement in air quality. However, increased humidity can also promote the formation of mould spores, potentially triggering respiratory issues. Temperature inversions, common during the cooler nights of the dry season, trap pollutants near ground level, worsening conditions. The months of August and September are typically the most challenging for respiratory health due to peak dust and burning activity. Sensitive groups – children, the elderly, and individuals with pre-existing respiratory conditions – should limit outdoor exertion during these periods. The wet season offers the most favourable conditions for outdoor activities, though vigilance regarding mould and humidity-related issues is advised. Monitoring local weather patterns and avoiding strenuous activity on windy days is crucial for maintaining respiratory health throughout the year.
