Konséguéla, situated in the Sikasso region of Mali at coordinates 12.4094, -5.8767, is a town deeply embedded within the Sudanese savanna ecosystem. The terrain is generally flat to gently undulating, characteristic of the broader Sahelian landscape, with an elevation hovering around 300-400 meters above sea level. This relatively low elevation contributes to limited atmospheric dispersion of pollutants. The town’s location isn’t directly adjacent to major bodies of water, though seasonal streams and smaller tributaries are present, influencing local humidity and dust levels. Konséguéla functions as a regional market centre, serving a largely agricultural hinterland. Surrounding the town are extensive fields dedicated to cotton, maize, and millet cultivation. This agricultural activity, while vital to the local economy, introduces particulate matter from land preparation, harvesting, and the burning of agricultural residue – a significant contributor to air pollution. The urban-rural gradient is pronounced; the town itself is relatively compact, but quickly transitions to open farmland. Dust from these fields, exacerbated by wind erosion, is a constant factor. Limited industrial activity within Konséguéla itself means that the primary air quality concerns stem from domestic fuel use (wood and charcoal) and agricultural practices, rather than large-scale emissions. The prevailing winds, typically from the northeast during the dry season, carry dust and smoke across the town.

Konséguéla experiences a distinct wet and dry season, profoundly impacting air quality. The dry season, roughly November to May, is characterised by consistently high levels of particulate matter. Harmattan winds, originating from the Sahara, bring vast quantities of dust, reducing visibility and exacerbating respiratory issues. Temperatures soar during this period, promoting atmospheric stability and trapping pollutants near the ground. January to March are particularly challenging months for those with pre-existing respiratory conditions. The transition to the wet season, June to August, brings a dramatic improvement in air quality. Rainfall effectively washes away dust and suppresses agricultural burning. However, increased humidity can also foster mold growth indoors, impacting indoor air quality. September and October see a gradual return to drier conditions, with a resurgence of dust and the commencement of post-harvest burning, leading to a moderate increase in particulate matter. During the wet season, while outdoor air is cleaner, damp conditions can worsen asthma symptoms. Sensitive groups – children, the elderly, and those with respiratory illnesses – should limit strenuous outdoor activity during peak dust periods (January-March) and take precautions against mold exposure during the wet season. Monitoring local weather patterns and avoiding areas with active burning are crucial for protecting health.
