Gobārdānga, nestled in the North 24 Parganas district of West Bengal, India, occupies a relatively flat, low-lying terrain characteristic of the Ganges Delta. Situated at coordinates 22.8700°N, 88.7600°E, the city’s geography is profoundly shaped by its proximity to the Ichhamati River, which forms part of the India-Bangladesh border nearby. This riverine landscape contributes to high humidity and influences local wind patterns. Gobārdānga isn’t an industrial hub in the same vein as larger West Bengal cities, but it functions as a significant agricultural market and transport node for the surrounding rural areas. The dominant land use is intensive agriculture, primarily rice cultivation, with pockets of jute farming. This agricultural activity, while vital to the regional economy, introduces sources of particulate matter through crop residue burning and fertilizer use. The urban-rural gradient is sharp; Gobārdānga is surrounded by densely populated villages and agricultural land, meaning pollutants generated in these areas can easily impact the city’s air quality. The flat topography limits natural dispersion of pollutants, exacerbating localised air quality issues. The city’s position within the Indo-Gangetic Plain also means it’s susceptible to long-range transport of pollutants from other heavily industrialised regions of North India, particularly during the winter months. This confluence of factors creates a unique air quality profile for Gobārdānga.

Gobārdānga experiences a tropical monsoon climate, dictating a distinct wet and dry season pattern influencing air quality. The pre-monsoon months (March-May) see rising temperatures and stagnant air, leading to a build-up of dust and particulate matter from agricultural activities and road traffic. This period often experiences the poorest air quality. The arrival of the monsoon (June-September) brings relief through rainfall, effectively washing away pollutants and improving air quality significantly. However, increased humidity can also foster mould growth, impacting respiratory health. Post-monsoon (October-November) sees a gradual return of drier conditions and a resurgence of dust, alongside increased burning of crop residue after the harvest, again worsening air quality. Winter (December-February) is characterised by cooler temperatures and frequent temperature inversions, trapping pollutants near the ground. Calm winds and fog further exacerbate the situation, leading to consistently poor air quality. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the pre-monsoon and winter months. Maintaining good ventilation indoors and using air purifiers are recommended. Avoiding peak traffic hours and areas with active agricultural burning can also minimise exposure. The monsoon months generally offer the most favourable conditions for outdoor activities.
