Laksar, nestled in the Haridwar district of Uttarakhand, India, occupies a geographically significant position at the foothills of the Shivalik range. Located at approximately 29.7490° N, 78.0240° E and an elevation of around 270 meters (886 feet), the town’s terrain is characterized by gently sloping plains transitioning into the rugged hills. The proximity to the Ganges River, flowing just a short distance to the east, influences local climate and hydrology, though direct riverine pollution impacts are currently minimal. Laksar’s urban character is a blend of traditional settlement patterns and modern development, reflecting its role as a growing industrial and transportation hub. It sits within a distinct urban–rural gradient, with agricultural lands dominating the surrounding landscape, particularly to the west and south, where fertile plains support cultivation of crops like sugarcane and wheat. Further east, the landscape rises into the Shivalik hills, a crucial ecological barrier. The town’s location within the Ganga-Yamuna Doab, a region known for its rich alluvial soil, contributes to its agricultural productivity. Industrial activity, primarily related to sugar mills and related processing industries, is concentrated in and around Laksar, contributing to localized pollution sources. The prevailing winds, generally from the west during the monsoon and shifting to the east during the dry season, play a crucial role in dispersing or concentrating pollutants, impacting air quality across the region. The surrounding landscape, a mix of agricultural fields and the protective hills, significantly shapes Laksar’s microclimate and air circulation patterns.

Laksar’s air quality experiences a distinct seasonal cycle heavily influenced by meteorological conditions and agricultural practices. The pre-monsoon months (March-May) typically see the poorest air quality, driven by rising temperatures, stagnant air masses, and increased agricultural burning. Farmers often clear crop residue through burning, releasing significant particulate matter and contributing to haze. Temperature inversions, common during this period, trap pollutants near the ground, exacerbating the problem. The monsoon season (June-September) brings relief as increased rainfall and stronger winds naturally cleanse the atmosphere, significantly reducing pollution levels. However, heavy rainfall can also lead to localized flooding and associated waterborne pollutants. Post-monsoon (October-November) witnesses a gradual deterioration in air quality as temperatures drop and wind speeds decrease, with agricultural burning again becoming a factor. The winter months (December-February) are generally characterized by cooler temperatures and frequent fog, which can trap pollutants and reduce visibility. This period can be particularly challenging for individuals with respiratory conditions. Sensitive groups, including children, the elderly, and those with pre-existing respiratory illnesses, should limit outdoor activity during the pre-monsoon and post-monsoon seasons, particularly on days with visible haze or fog. Maintaining indoor air quality through ventilation and air purifiers is also advisable. Public awareness campaigns promoting cleaner agricultural practices and reducing reliance on burning are crucial for improving Laksar’s long-term air quality.
