Assessment of air quality and possible mitigation options in Kathmandu valley: An overview
- Himalayan Climate Center, Kathmandu (Nepal)
Kathmandu is an elevated valley surrounded by high hills. The weather and climate patterns, though monsoonal, are influenced largely by topography. The city is growing rapidly but not in a well planned way. Construction industries, mainly residential houses and other building complex, are inducing direct suspension of dust particles. The brick kilns and cement factory in support of the construction works are major source of pollution. The rapid increase in population and subsequent increase of all types of vehicles (without emission controls) have further aggravated the situation. The topography restricts horizontal flushing out of the pollutants but intense convection may help to lift the pollutants up to the cloud base. Systematic measurements of the air quality along with other meteorological parameters should be initiated to understand fully the problem and possible means of ventilation.
