Khandpara, nestled in the Nayagarh district of Odisha, India, occupies a geographically significant position within the Eastern Ghats region. Located at approximately 20.2644° N, 85.1767° E, the town’s terrain is characterized by undulating hills and valleys, typical of the region's geomorphology. The elevation, while not exceptionally high, contributes to localized microclimates and influences air circulation patterns. Khandpara sits within a predominantly rural landscape, transitioning gradually towards a more urban character as it develops. The surrounding area is largely agricultural, with rice cultivation being a dominant feature, interspersed with patches of deciduous forests. This proximity to agricultural lands introduces potential sources of particulate matter, particularly during harvest seasons when burning of crop residue can occur. While not directly adjacent to a major river, the town benefits from the presence of smaller streams and seasonal water bodies, which can influence local humidity and temperature. The nearest significant industrial belt lies further east, towards the coastal regions of Odisha, but transportation corridors connecting Khandpara to these areas can still carry pollutants. The urban–rural gradient around Khandpara is relatively gentle, with smaller villages and agricultural fields blending seamlessly into the town's periphery. This spatial arrangement means that air quality is susceptible to both local agricultural practices and broader regional pollution trends, making it a complex interplay of factors.

Khandpara’s air quality experiences a distinct seasonal cycle dictated by the region’s tropical climate and monsoon patterns. The pre-monsoon season (March-May) often witnesses a gradual increase in pollutants, driven by rising temperatures and decreasing rainfall. This period is characterized by stagnant air conditions, particularly during the hottest days, which can trap pollutants close to the ground. The monsoon season (June-September) brings a welcome respite, with frequent rainfall effectively washing away particulate matter and diluting gaseous pollutants. Wind speeds generally increase during this period, facilitating dispersion. The post-monsoon season (October-November) can see a resurgence of pollution as agricultural burning becomes more prevalent, coinciding with the harvest of key crops. The dry, cooler months of December and January often experience periods of fog, which further exacerbates air quality issues by trapping pollutants and reducing visibility. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the pre-monsoon and post-monsoon seasons, limiting outdoor activities during peak pollution episodes. During the monsoon, while air quality generally improves, heavy rainfall can still lead to localized flooding and associated issues. Maintaining indoor air quality through ventilation and air purification can be beneficial throughout the year, particularly during periods of elevated pollution. Awareness of agricultural burning practices and their impact on air quality is crucial for community health.
