Shivganj, nestled within the arid landscape of Rajasthan, India, occupies a geographically significant position at approximately 25.15°N latitude and 73.07°E longitude. The town’s elevation, typical of the region, contributes to specific meteorological conditions impacting air quality. Shivganj is situated within the Hadoti region, characterized by undulating terrain and the presence of the Chambal River basin to the east, though the town itself isn’t directly on the river. The surrounding landscape is predominantly semi-arid, featuring scrubland vegetation and rocky outcrops. Agriculture forms a crucial part of the local economy, with rain-fed farming of crops like millet and pulses prevalent in the surrounding areas. While Shivganj isn’t a major industrial hub, smaller-scale brick kilns and stone crushing units contribute to particulate matter emissions. The urban-rural gradient is relatively sharp; the town represents a concentrated settlement amidst a sparsely populated rural hinterland. Dust from agricultural activities and unpaved roads, combined with localized industrial emissions, are key factors influencing the baseline air quality. The lack of significant natural wind corridors to flush out pollutants exacerbates the situation, particularly during calmer weather conditions. The town’s location within a rain shadow area limits precipitation, reducing the natural cleansing effect of rainfall.

Shivganj experiences a distinct seasonal air quality pattern. The pre-monsoon months of April and May are typically the worst, with soaring temperatures and dry winds stirring up dust from agricultural lands and construction activities. Temperature inversions, common during these months, trap pollutants near the ground, worsening conditions. The arrival of the monsoon in July-August brings temporary relief, as rainfall washes away particulate matter and cooler temperatures reduce emissions. However, increased humidity can also promote the formation of secondary pollutants. Post-monsoon, from September to November, air quality gradually deteriorates as temperatures rise and agricultural burning increases, particularly after the harvest. Winter, from December to February, sees cooler temperatures and calmer winds, leading to the accumulation of pollutants from domestic heating (wood and dung burning) and vehicular emissions. Fog, a frequent occurrence during winter mornings, further exacerbates particulate matter concentrations. Sensitive groups – children, the elderly, and those with respiratory conditions – should avoid prolonged outdoor activity during April-May and December-January. Monitoring local weather patterns and avoiding peak pollution hours is advisable. The monsoon months generally offer the most favourable conditions for outdoor activities.
