Bezou, nestled within the Béni Mellal-Khénifra region of Morocco, occupies a geographically significant position at approximately 32.08° N, 7.05° W. The city’s terrain is characterized by a gently sloping landscape, transitioning from the foothills of the High Atlas Mountains to the fertile plains of the Tadla region. This location dictates a semi-arid climate, influenced by both the mountains and the proximity to the Atlantic coast, roughly 80 kilometers west. Bezou sits within a predominantly agricultural zone, with extensive olive groves, fruit orchards, and cereal fields dominating the surrounding landscape. This agricultural activity, while vital to the regional economy, contributes to localized air quality concerns, particularly from seasonal burning practices and fertilizer use. The urban–rural gradient around Bezou is relatively gradual; small villages and agricultural hamlets are interspersed throughout the wider area, creating a mosaic of land use. The elevation, around 550 meters above sea level, contributes to occasional temperature inversions, especially during the cooler months, which can trap pollutants near the ground. While Bezou lacks direct access to major rivers, groundwater resources are important for irrigation, and the overall topography encourages localized wind patterns that can either disperse or concentrate pollutants depending on the season and weather conditions. The absence of large-scale industrial zones immediately adjacent to Bezou mitigates some pollution risks, but transportation corridors connecting the region to larger urban centers do introduce vehicular emissions.

Bezou’s air quality experiences a distinct seasonal cycle dictated by its semi-arid climate and agricultural practices. The dry season, spanning roughly from April to October, typically sees increased particulate matter concentrations. Agricultural burning, used for land clearing and crop residue disposal, is a significant contributor during this period, peaking in May and September. Strong, dry winds, common during the summer months, can exacerbate the dispersal of these particles, but also occasionally transport dust from the surrounding plains. Temperature inversions are less frequent during the summer due to the intense solar heating, which promotes atmospheric mixing. Conversely, the cooler, wetter months (November to March) often bring periods of stagnant air and increased humidity. Fog, particularly in December and January, can trap pollutants close to the ground, leading to localized episodes of reduced visibility and potentially elevated air quality concerns. While rainfall helps to cleanse the atmosphere, the reduced wind speeds during these months limit dispersion. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during periods of agricultural burning and fog. Outdoor activities are generally more favorable during the spring (March-April) and autumn (October-November) when temperatures are moderate, and rainfall is more frequent, helping to clear the air. The impact of dust storms originating from the Sahara Desert, while less frequent than in more southerly regions, can occasionally affect Bezou’s air quality, particularly during the spring transition.
