Rejiche, a municipality within the Mahdia Governorate of Tunisia, occupies a strategic position in the country’s east-central coastal plain. Located at approximately 35.47°N latitude and 11.03°E longitude, the city benefits from a Mediterranean climate but is also susceptible to regional pollution patterns. The terrain is generally flat, transitioning gently inland towards rolling hills, influencing local wind patterns. Rejiche sits relatively close to the Mediterranean Sea, approximately 15 kilometers distant, which provides some moderating influence on temperatures and can contribute to coastal breezes that disperse pollutants. However, this proximity also means potential for salt spray and humidity-related atmospheric reactions. The surrounding landscape is a mix of agricultural land – olive groves and cereal crops are prevalent – and increasingly, areas dedicated to tourism, particularly along the coast. While Rejiche itself isn’t a major industrial hub, its position within the broader Mahdia region, which has some light industrial activity related to food processing and textiles, means it can experience pollutant transport. The urban-rural gradient is relatively sharp, with agricultural areas immediately surrounding the town, and a gradual transition to more sparsely populated regions further inland. This gradient impacts air quality as agricultural practices (fertilizer use, burning of agricultural waste) can contribute to localised pollution events.

Rejiche experiences a distinct seasonal air quality pattern dictated by its Mediterranean climate. Summer (June-August) often sees relatively good air quality, driven by prevailing northerly winds that sweep across the Mediterranean, dispersing pollutants. However, high temperatures can exacerbate ground-level ozone formation, particularly on calm days. Autumn (September-November) brings a transition period; agricultural burning of crop residue becomes more common, leading to spikes in particulate matter. This is often coupled with increased humidity and potential for temperature inversions, trapping pollutants near the ground. Winter (December-February) is generally the period of poorest air quality. Reduced wind speeds, increased reliance on heating (often wood or less efficient fuels), and temperature inversions create stagnant air conditions, concentrating pollutants. Fog, common during these months, further exacerbates the issue. Spring (March-May) sees improving conditions as temperatures rise and winds become more frequent, but dust storms originating from the Sahara Desert can occasionally impact air quality. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during autumn and winter months. Monitoring wind direction and avoiding periods of calm, foggy weather is advisable year-round.
