Climate change poses a growing threat to Kathmandu's air quality
As Kathmandu endures severe air pollution issues, exacerbated by climate change, residents face increased health risks.
Abhaya Raj Joshi reports for Mongabay.
In short:
- Local emissions and geographical features contribute to pollution, which is intensified by climate warming.
- Reduced rainfall and prolonged dry periods due to climate change worsen air quality.
- Wildfires contribute significantly to the pollution levels, with the situation expected to deteriorate as global temperatures rise.
Key quote:
“In the short term, the level of pollution in Kathmandu is determined by the amount of rainfall it receives. However, the amount and frequency of rainfall in Nepal has been changing due to rising temperatures.”
— Sudeep Thakuri, climatologist
Why this matters:
The health implications of deteriorating air quality in Kathmandu are profound, particularly for vulnerable populations such as children, the elderly, and those with preexisting respiratory and cardiovascular conditions. The increased pollutants can lead to higher incidences of asthma attacks, lung infections, and chronic obstructive pulmonary diseases. Furthermore, the economic impact, including healthcare costs and lost labor productivity, can be substantial, straining local economies.
