Şabrātah, nestled within the An Nuqāţ al Khams region of Libya (coordinates 32.7922, 12.4842), occupies a geographically significant position within the Saharan coastal plain. The city’s terrain is predominantly flat, characteristic of the surrounding desert landscape, with gentle undulations marking the transition towards the interior highlands. Situated approximately 15 kilometers inland from the Mediterranean Sea, Şabrātah benefits from a relatively moderate coastal climate, though the desert’s influence remains substantial. The immediate surrounding landscape is dominated by arid scrubland and sand dunes, gradually giving way to more rugged terrain as one moves southwards. The urban fabric of Şabrātah is a blend of traditional Libyan architecture and more modern developments, reflecting its growth as a regional trading hub. While not directly adjacent to major rivers, the proximity to the Mediterranean provides a source of humidity, albeit limited, and influences local wind patterns. The region’s economy is a mix of agriculture (date palms and olives are cultivated in oases nearby), fishing along the coast, and some light industry. An urban–rural gradient is clearly visible, with Şabrātah acting as a focal point for surrounding agricultural communities. The lack of significant topographic barriers within a 50km radius, combined with the prevailing wind patterns from the Sahara, contributes to a potential for the accumulation of pollutants, particularly during periods of stagnant air. The city’s location, therefore, presents unique challenges regarding air quality management, requiring consideration of both local emissions and long-range transport of desert dust and pollutants.

Şabrātah’s air quality experiences a distinct seasonal cycle dictated by its Mediterranean-Saharan climate. The warmer months, spanning from May to September, are typically characterized by high temperatures and reduced precipitation, leading to increased evaporation and a greater prevalence of Saharan dust intrusions. These dust storms, often carrying fine particulate matter, significantly degrade air quality, reducing visibility and posing respiratory health risks. The summer heat also encourages increased use of air conditioning, potentially contributing to localized ozone formation. Conversely, the cooler months (October to April) generally see improved air quality, although occasional cold air masses can trigger temperature inversions, trapping pollutants near the ground. During these inversions, particularly in November and December, stagnant air conditions can lead to a build-up of emissions from local sources. The transitional spring and autumn months (March-April and September-October) are often the most variable, with periods of clear skies interspersed with dust events. Fog, though infrequent, can also occur during the cooler months, further exacerbating pollution by trapping pollutants. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during periods of Saharan dust storms and temperature inversions, limiting outdoor activity and utilizing air filtration systems where possible. The months of June, July, and August are generally the most challenging for air quality, while February and March often offer the most favourable conditions for outdoor pursuits.
