Do’stlik Shahri, nestled within the Jizzax Region of Uzbekistan, occupies a unique geographic position in the central part of the country. Situated at coordinates 40.5247° N, 68.0358° E, the city lies within a valley landscape, characteristic of much of the region. The terrain is gently undulating, transitioning from fertile agricultural lands to the foothills of the Tian Shan mountains to the east. This valley setting, at an elevation of approximately 720 meters (2,362 feet), significantly influences local air quality. The surrounding landscape is dominated by cotton fields, orchards, and wheat farms, typical of Jizzax’s agricultural focus. While no major bodies of water are immediately adjacent, the Syr Darya River flows within the broader region, impacting humidity levels. Do’stlik Shahri isn’t a major industrial hub, but the presence of smaller-scale manufacturing and processing facilities related to agriculture contributes to localised emissions. The urban-rural gradient is relatively sharp; the city itself is compact, quickly giving way to open farmland. This proximity to agricultural activity means seasonal burning of crop residue can be a significant factor in air pollution episodes. The valley’s topography can also trap pollutants, especially during periods of calm weather, exacerbating air quality concerns. The prevailing winds, generally from the northwest, can transport pollutants from other regional centres.

Air quality in Do’stlik Shahri exhibits a distinct seasonal pattern. Spring (March-May) often sees a deterioration in air quality due to the widespread burning of agricultural waste following the harvest, releasing particulate matter and other pollutants. Dust storms, originating from the arid regions to the west, are also common during this period, further impacting visibility and respiratory health. Summers (June-August) are typically drier and hotter, with relatively stable atmospheric conditions. While industrial activity continues, the heat can exacerbate ground-level ozone formation. Autumn (September-November) brings a temporary improvement as temperatures cool and agricultural burning subsides. However, temperature inversions become more frequent, trapping pollutants near the ground. Winter (December-February) is characterised by cold temperatures and increased reliance on coal and wood for heating, leading to elevated levels of particulate matter, particularly PM2.5. Calm wind conditions during winter further worsen the situation. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during spring burning season and winter heating periods. Months of July and August generally offer the most favourable conditions for outdoor activity, though ozone levels should still be considered. Monitoring wind patterns and avoiding strenuous activity on still, cold days is advisable.
