Arlit, situated in the Agadez Region of Niger, is a town profoundly shaped by its desert environment and the presence of significant uranium deposits. Located at coordinates 18.7333, 7.3833, the town lies within the Aïr Mountains, a rugged massif rising from the surrounding Sahara. The terrain is characterised by rocky plateaus, sandy plains, and ephemeral wadis – dry riverbeds that briefly fill during the infrequent rainfall. Arlit’s elevation, around 730 meters, contributes to relatively cooler temperatures compared to the lower-lying desert. The town’s urban character is largely dictated by the mining industry; it’s a functional settlement built to support uranium extraction. The surrounding landscape is almost entirely arid, with sparse vegetation limited to drought-resistant shrubs and acacia trees. There are no significant bodies of water nearby, and agricultural zones are minimal, consisting of small-scale oasis farming. The urban-rural gradient is stark; Arlit is a concentrated settlement amidst a vast, sparsely populated desert. This isolation, coupled with the industrial activity, significantly impacts air quality. Dust storms are frequent, carrying particulate matter across the region, and the uranium mining operations release radioactive dust and other pollutants, exacerbating the problem. The prevailing winds, often from the northeast, transport these pollutants across the town and surrounding areas.

Arlit experiences a harsh desert climate with a distinct wet and dry season, rather than traditional four seasons. The dry season, spanning roughly November to June, is characterised by intense heat, low humidity, and frequent dust storms. This is when air quality is typically at its worst. The dry, hot air allows particulate matter from mining activities and wind erosion to remain suspended for longer periods. January to March are particularly challenging due to the Harmattan wind, bringing vast quantities of Saharan dust. The brief wet season, from July to October, offers temporary relief. While rainfall is limited, it helps to suppress dust and wash pollutants from the air. However, even during the wet season, localised dust from mining operations can still be a concern. August and September, with the highest probability of rainfall, are the most favourable months for outdoor activity, though humidity increases. Temperature inversions, common during cooler nights, can trap pollutants near the ground, worsening air quality even during the wet season. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor exposure during dust storms and periods of high industrial activity, regardless of the season. Staying indoors with windows closed and using air filtration systems are recommended.
