Beni Fouda, nestled within the Sétif Province of Algeria, occupies a geographically significant position in the Haut Plateaux region. Located at coordinates 36.2861° N, 5.6072° E, the city sits at an elevation of approximately 900 meters above sea level, contributing to a cooler, more temperate climate than many other parts of Algeria. The surrounding landscape is characterised by rolling plateaus and fertile agricultural lands, primarily dedicated to cereal crops and olive groves. Beni Fouda isn’t directly adjacent to a major body of water, though seasonal streams and wadis traverse the region, influencing local microclimates. The urban character is typical of a smaller Algerian city, with a blend of traditional housing and more modern construction. While not a major industrial hub itself, Beni Fouda’s proximity to Sétif, a more substantial industrial centre, means it can experience pollutant transport. The urban-rural gradient is relatively sharp, with agricultural areas immediately bordering the city limits. This proximity introduces potential for agricultural burning contributing to particulate matter, while the plateau’s topography can trap pollutants, limiting dispersion, particularly during stable atmospheric conditions. The prevailing winds, generally from the west, play a crucial role in pollutant movement, sometimes carrying dust from the Sahara Desert.

Air quality in Beni Fouda exhibits a distinct seasonal pattern. Spring (March-May) often sees a moderate increase in particulate matter due to agricultural activities – land preparation and burning of crop residue. Winds can be variable, sometimes aiding dispersion, other times creating localised pockets of pollution. Summer (June-August) typically offers the cleanest air, with higher temperatures promoting better atmospheric mixing and rainfall washing away pollutants. However, prolonged drought conditions can exacerbate dust levels. Autumn (September-November) marks a transition period, with decreasing temperatures and increasing stability in the atmosphere. This can lead to temperature inversions, trapping pollutants near the ground, particularly from domestic heating sources as evenings cool. November often sees a noticeable decline in air quality. Winter (December-February) is generally the most challenging period. Increased reliance on wood and charcoal for heating, combined with frequent temperature inversions and calm wind conditions, results in elevated levels of particulate matter and other combustion byproducts. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor exertion during these months. Fog, common in the cooler months, can further concentrate pollutants. Avoiding outdoor activity during calm, cold mornings is advisable.
