Chanderi, nestled in the Ashoknagar district of Madhya Pradesh, India, occupies a unique geographic position within the Malwa Plateau. Situated at coordinates 24.7200°N, 78.1300°E, the town’s terrain is characterised by undulating hills and plains, an elevation of approximately 378 meters above sea level contributing to localized weather patterns. The surrounding landscape is predominantly rural, dominated by agricultural lands cultivating wheat, soybeans, and cotton. The Betwa River flows nearby, influencing local humidity and potentially contributing to localized fog formation during cooler months. While not directly within a major industrial belt, Chanderi’s proximity to industrial areas in nearby cities like Gwalior and Bhopal means it can experience regional transport of pollutants. The urban-rural gradient is quite sharp; the town itself is relatively compact, with surrounding villages engaged in agriculture. This creates a dynamic where agricultural practices – including seasonal crop burning – and domestic fuel use (wood and biomass) significantly impact local air quality. Dust from unpaved roads and construction activities also contributes to particulate matter levels. The town’s location within a valley can sometimes trap pollutants, exacerbating air quality issues, particularly during periods of calm winds.

Chanderi experiences a distinct seasonal air quality narrative. The post-monsoon period (October-November) often sees a deterioration in air quality due to stagnant air and the practice of crop residue burning following the harvest season. Cooler temperatures lead to temperature inversions, trapping pollutants near the ground. Winter (December-February) brings drier conditions and increased reliance on biomass for heating, further elevating particulate matter. Fog formation is common, exacerbating visibility and trapping pollutants. March-May marks the pre-monsoon season, with rising temperatures and dust storms contributing to increased particulate matter concentrations. The monsoon season (June-September) generally offers the cleanest air, as rainfall washes away pollutants and increased humidity suppresses dust. However, increased cloud cover can also lead to temperature inversions. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during October-November and December-February. Avoiding peak hours near roadways is advisable year-round. Monitoring local weather reports and being mindful of agricultural burning practices can help individuals mitigate exposure. The monsoon offers the most favourable conditions for outdoor activities.
