Bougtob, nestled within the El Bayadh province of Algeria, occupies a unique geographic position in the country’s northwest. Located at coordinates 34.0425° N, 0.0892° E, the city sits on the northern edge of the High Plateaus, a vast, undulating landscape characterized by steppes and semi-arid conditions. The terrain is generally flat to gently rolling, rising slightly towards the south. Bougtob’s elevation, around 800 meters above sea level, contributes to cooler temperatures than coastal regions, but also influences air dispersion patterns. Unlike coastal cities, Bougtob is far removed from significant bodies of water, lacking the moderating influence of the Mediterranean Sea. The surrounding area is predominantly agricultural, with wheat and barley cultivation being common, alongside some pastoral activities. There are no major industrial belts immediately adjacent to Bougtob, though regional mining activities further south can contribute to dust transport. The urban-rural gradient is relatively sharp; Bougtob represents a concentrated settlement within a sparsely populated region. This isolation, while offering a degree of natural air cleansing, also means limited resources for comprehensive air quality monitoring and mitigation. Dust storms, originating from the Sahara Desert to the south, are a frequent occurrence, significantly impacting local air quality.

Bougtob experiences a distinct Mediterranean-influenced climate, with hot, dry summers and mild, wetter winters. Air quality in Bougtob follows a predictable seasonal pattern. Spring (March-May) sees a gradual increase in particulate matter as agricultural activities intensify, including land preparation and potential burning of crop residue. Summer (June-August) is typically the period of best air quality, due to prevailing winds that help disperse pollutants and infrequent rainfall to wash them away. However, intense heat can exacerbate ozone formation. Autumn (September-November) brings a resurgence of dust, carried by shifting wind patterns from the Sahara, leading to noticeable declines in air quality. Winter (December-February) is characterized by temperature inversions, trapping pollutants close to the ground, particularly from residential heating using wood and other biomass fuels. These inversions, combined with reduced wind speeds, can create stagnant air conditions. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during autumn and winter months. Spring can also pose risks due to agricultural dust. Favour outdoor activities during summer afternoons when winds are typically stronger, but be mindful of potential ozone levels during peak heat.
