Kushk, nestled within the Herat Province of Afghanistan, occupies a geographically significant position in the western part of the country. Located at coordinates 33.2956°N, 61.9522°E, the city sits amidst a landscape dominated by arid and semi-arid terrain, characteristic of the broader Afghan plateau. The surrounding area is largely comprised of plains and low hills, transitioning towards the more rugged mountains further west and south. Kushk’s elevation, approximately 880 meters (2,887 feet) above sea level, influences temperature patterns and atmospheric circulation. The Hari River flows relatively close to Kushk, providing a crucial water source but also potentially contributing to localised humidity and influencing wind patterns. The urban character of Kushk is typical of a regional centre in Afghanistan, with a mix of traditional mud-brick housing and more modern constructions. The surrounding agricultural zones, primarily focused on wheat, barley, and fruit orchards, contribute to seasonal biomass burning, a key factor in local air quality. The urban-rural gradient is relatively sharp, with agricultural land immediately bordering the city limits. The proximity to regional trade routes also means increased vehicle traffic, impacting emissions. This combination of geographical and human factors creates a unique air quality profile for Kushk.

Kushk experiences a distinct seasonal air quality pattern dictated by Afghanistan’s continental climate. Spring (March-May) sees a temporary improvement as rainfall washes particulate matter from the atmosphere, though agricultural burning begins to increase as fields are prepared for planting. Summer (June-August) brings hot, dry conditions and often dust storms originating from the surrounding deserts, significantly degrading air quality. Temperature inversions, common during calm summer nights, trap pollutants near the ground. Autumn (September-November) is generally the clearest period, with cooler temperatures and reduced agricultural activity. However, increased heating with solid fuels as temperatures drop can lead to localised indoor and outdoor pollution. Winter (December-February) is the most challenging period. Cold temperatures promote the widespread use of coal, wood, and other biomass for heating, resulting in high concentrations of particulate matter (PM2.5 and PM10). Weak winds and frequent temperature inversions exacerbate the problem, trapping pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during winter months and periods of visible haze. Avoiding peak burning times in spring and autumn is also advisable. Monitoring wind direction can help predict pollutant transport.
