Itārsi, nestled in the heart of Madhya Pradesh, India, occupies a crucial geographic position within the Satpura range. Located at 22.6115°N, 77.7623°E, the city sits at an elevation of approximately 320 meters (1050 feet), influencing its climate and air quality. Itārsi isn’t situated directly on a major river, but is close to the Tapti River, which plays a role in regional humidity and potential for localized fog formation. The surrounding landscape is characterised by undulating hills and dense deciduous forests, typical of the Satpura region. Itārsi functions as a significant railway junction, a major contributor to local economic activity but also a source of particulate matter from shunting and diesel locomotives. The city’s urban character is a blend of commercial activity centered around the railway and surrounding agricultural lands. A noticeable urban-rural gradient exists, with agricultural practices – primarily cotton, wheat, and pulses – dominating the periphery. Industrial activity is relatively limited within Itārsi itself, but the presence of small-scale brick kilns and stone crushing units contributes to dust pollution. The terrain funnels winds from the north and south, potentially trapping pollutants during periods of low wind speed, exacerbating air quality concerns. The city’s location within a valley also increases the likelihood of temperature inversions, further hindering pollutant dispersion.

Itārsi experiences a distinct seasonal air quality pattern. The post-monsoon period, from October to November, often sees a build-up of pollutants as cooler temperatures and calmer winds trap emissions. This is compounded by agricultural residue burning following the harvest season, significantly impacting particulate matter levels. December and January represent the most challenging months for air quality, with frequent temperature inversions and fog creating stagnant conditions. Sensitive individuals, including children and the elderly, should limit outdoor exertion during these months. The arrival of the summer, from March to May, brings increased temperatures and convective mixing, which generally improves air quality by dispersing pollutants. However, dust storms originating from the arid regions of Rajasthan can temporarily worsen conditions. The monsoon season, from June to September, offers the cleanest air, as rainfall effectively washes away pollutants. While humidity increases, the cleansing effect of the rain is substantial. However, increased moisture can also promote mold growth indoors. Throughout the year, diesel vehicle emissions from the railway junction contribute to localized pollution hotspots. Avoiding peak traffic hours and using respiratory protection during periods of high pollution are recommended.
