Xarardheere, situated in the Mudug region of Somalia at approximately 4.6544° N, 47.8575° E, occupies a geographically significant position along the Juba River’s floodplain. The city’s terrain is predominantly flat, characteristic of the broader Somali coastal plains, with elevations rarely exceeding a few meters above sea level. This low-lying location makes Xarardheere particularly vulnerable to flooding during the rainy seasons, a factor that can influence local air quality by mobilizing dust and particulate matter. The surrounding landscape is a mosaic of semi-arid grasslands, scrubland, and agricultural fields, primarily supporting sorghum, maize, and vegetables. The Juba River itself is a crucial lifeline, providing irrigation and supporting livestock grazing, but also contributing to humidity and potential for waterborne disease transmission. There are no significant industrial belts directly adjacent to Xarardheere; the regional economy is largely agrarian and pastoral. The urban–rural gradient transitions rapidly, with the city acting as a market hub for surrounding rural communities. The proximity to the Indian Ocean, approximately 100km away, introduces a maritime influence, occasionally bringing in sea salt aerosols. Prevailing winds generally flow from the southeast, carrying moisture and potential pollutants from the coast and inland agricultural areas. The flat topography limits vertical mixing of air, potentially trapping pollutants close to the ground, especially during periods of calm weather. The lack of substantial natural barriers means that dust storms originating from the interior can readily impact air quality within the city.

Xarardheere experiences a tropical climate with distinct wet and dry seasons, significantly impacting air quality patterns. The longer dry season, typically spanning from April to October, is characterized by intense solar radiation, high temperatures, and minimal rainfall. This period often sees elevated levels of particulate matter due to windblown dust from agricultural lands and exposed soil. The lack of vegetation cover during this time exacerbates dust generation. Conversely, the shorter wet season (November to March) brings sporadic rainfall, which can temporarily cleanse the air by washing away pollutants and suppressing dust emissions. However, heavy downpours can also lead to flooding, mobilizing sediment and increasing humidity, which can affect respiratory health. Temperature inversions, though less frequent than in cooler climates, can occasionally occur during the cooler months (December-January), trapping pollutants near the ground. Fog, though rare, can also form under specific atmospheric conditions, further reducing air quality. The months of June, July, and August are generally the most challenging for air quality due to persistent dry conditions and frequent dust storms. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should limit outdoor activity during these periods and consider using face masks. During the wet season, while overall air quality improves, vigilance regarding waterborne illnesses is crucial, and precautions should be taken to avoid exposure to floodwaters.
