What Causes Kathmandu AQI to Spike?
Kathmandu’s AQI often spikes due to a combination of natural and human-made factors. The city’s geographical location, nestled in a valley surrounded by mountains, exacerbates the problem. This topography creates a natural trap for pollutants, especially during winter when temperature inversions prevent warm air from rising. As a result, pollutants like PM2.5 and PM10 linger close to the ground, worsening air quality. But geography alone doesn’t explain the severity of Kathmandu AQI levels. Human activities play a significant role as well.
Vehicle Emissions
One of the primary contributors to Kathmandu’s poor air quality is vehicle emissions. The city’s roads are often congested with old, poorly maintained vehicles that emit high levels of pollutants. Diesel-powered buses and trucks are particularly problematic, releasing large quantities of nitrogen oxides (NOx) and particulate matter. The rapid increase in private vehicle ownership has further compounded the issue, making transportation a major source of air pollution in the valley.
Industrial Activities
Industrial activities, including brick kilns and manufacturing units, are another significant contributor to Kathmandu AQI. Brick kilns, which operate on the outskirts of the city, burn coal and other fossil fuels, releasing harmful pollutants into the air. These pollutants not only degrade air quality but also contribute to soil and water contamination. Despite regulations aimed at controlling emissions, enforcement remains weak, allowing these industries to continue polluting unchecked.
Open Burning of Waste
Another factor that spikes Kathmandu AQI is the open burning of waste. In many parts of the city, garbage is burned openly due to inadequate waste management systems. This practice releases toxic chemicals and particulate matter into the air, further deteriorating air quality. The lack of awareness and infrastructure for proper waste disposal exacerbates the problem, making it a persistent challenge.
Dust from Construction Sites
Construction activities in Kathmandu have surged in recent years, contributing to the city’s air pollution woes. Dust from construction sites, coupled with poorly paved roads, adds to the particulate matter in the air. This is particularly problematic during the dry season when wind carries dust particles across the city. While some construction companies have adopted measures to control dust, such as covering materials and using water sprays, these practices are not yet widespread.
Understanding the causes of Kathmandu AQI spikes is essential for addressing the issue effectively. By identifying the sources of pollution, policymakers and individuals can work together to implement targeted solutions. Whether it’s transitioning to cleaner fuels, improving waste management, or regulating industrial emissions, every step counts in the fight for cleaner air.
