Djouab, nestled within the Médéa Province of Algeria, occupies a geographically significant position at approximately 36.13° N, 3.43° E. The city’s setting is characterized by a gently undulating terrain, part of the Tell Atlas mountains, rising to an elevation of around 1000 meters above sea level. This elevation contributes to a cooler climate compared to coastal regions, but also creates conditions conducive to temperature inversions, a key factor influencing air quality. Djouab is surrounded by a landscape dominated by semi-arid scrubland and agricultural fields, primarily cultivating cereals and olives – a rural-urban gradient is evident as the city expands outwards. The nearest substantial body of water, the Tafna River, lies a short distance to the north, offering some localized humidity but not significantly impacting broader air quality patterns. The region’s industrial activity is relatively limited compared to larger Algerian cities like Algiers, but there are small-scale workshops and agricultural processing facilities within the Médéa province, potentially contributing localized emissions. Djouab’s location within a valley system can trap pollutants, particularly during periods of low wind. The surrounding mountains act as a barrier, limiting the dispersion of airborne contaminants. The city’s relatively small population (approximately 16,751) suggests a primarily residential character, though increased traffic from connecting roads could still be a factor in local air quality. The overall topography and regional land use patterns combine to create a microclimate that can exacerbate air pollution challenges.

Djouab’s air quality experiences a distinct seasonal cycle dictated by its Mediterranean climate. The dry summer months (June-August) are typically characterized by high temperatures and minimal rainfall, leading to stagnant air conditions. The lack of precipitation and reduced vegetation cover means fewer natural filters for pollutants. Temperature inversions are common during this period, trapping emissions close to the ground, particularly in the evenings and early mornings. Dust storms, originating from the Sahara Desert, can also significantly degrade air quality, carrying fine particulate matter over long distances. Autumn (September-November) brings a gradual shift, with increased rainfall and slightly cooler temperatures, which generally improves air quality as pollutants are washed from the atmosphere. Winter (December-February) often sees the most stable atmospheric conditions, with frequent fog and temperature inversions, again leading to pollutant accumulation. While rainfall is more frequent than in summer, the cold, still air can still trap pollutants. Spring (March-May) offers the most favourable conditions, with increasing wind speeds and rainfall, effectively dispersing pollutants and cleansing the air. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the summer months and periods of fog, limiting outdoor activity during peak pollution times. Maintaining indoor air quality through ventilation and air purification can also be beneficial. The agricultural practices in the surrounding areas, particularly the use of fertilizers and pesticides, can also contribute to seasonal fluctuations in air quality, especially during planting and harvesting seasons.
