Rāisinghnagar, nestled in the arid plains of Rajasthan, India, occupies a geographically significant position within the Shekhawati region. Located at approximately 29.53°N, 73.45°E and an elevation of around 318 meters (1043 feet) above sea level, the city’s terrain is predominantly flat, characteristic of the Thar Desert’s fringes. The surrounding landscape is a mosaic of agricultural fields – primarily wheat, barley, and pulses – interspersed with scrubland and sparsely vegetated dunes. This agricultural activity, while vital to the local economy, contributes to seasonal dust and particulate matter. Rāisinghnagar’s proximity to the Luni River, though not directly adjacent, influences local microclimates and can occasionally provide some respite from extreme heat. The urban–rural gradient transitions rapidly; the city itself is relatively compact, with a discernible shift to agricultural land within a few kilometers. The region is part of a broader industrial belt focused on textiles and light manufacturing, though Rāisinghnagar’s industrial presence is comparatively modest. However, the transportation network connecting it to larger industrial hubs in Rajasthan, including Jaipur and Bikaner, introduces vehicular emissions. The flat topography and limited natural barriers exacerbate the accumulation of pollutants, particularly during periods of stagnant air. The prevailing winds, often light and variable, struggle to disperse emissions effectively, leading to localized air quality challenges. The city’s location within a semi-arid climate zone further contributes to dust generation and the potential for temperature inversions, trapping pollutants close to the ground.

Rāisinghnagar’s air quality follows a distinct seasonal pattern dictated by its arid climate and agricultural practices. The winter months (November to February) typically experience the poorest air quality. Cold temperatures frequently lead to temperature inversions, where a layer of warm air traps cooler air and pollutants near the ground. Fog, common during this period, further restricts dispersion. Agricultural burning, a practice used to clear crop residue, significantly elevates particulate matter levels, particularly in November and December. Spring (March to May) brings a gradual improvement as temperatures rise and winds become more frequent, aiding in pollutant dispersal. However, dust storms, common in Rajasthan, can temporarily degrade air quality. The monsoon season (June to September) offers a period of relative relief. Rainfall washes away pollutants, and increased wind speeds enhance ventilation. However, heavy rainfall can also lead to waterlogging and the release of pollutants from stagnant water sources. The post-monsoon period (October) sees a return to drier conditions, with a gradual increase in dust and a precursor to the winter pollution peak. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the winter months, limiting outdoor activity during peak pollution episodes. During dust storm events, wearing masks and avoiding strenuous outdoor exertion is advisable. Agricultural workers should be particularly mindful of exposure to smoke from crop residue burning and take appropriate protective measures. Maintaining indoor air quality through ventilation and air purification can also mitigate the impacts of poor outdoor air quality.
