Kathmandu Valley residents are facing a surge in air pollution, with the Air Quality Index (AQI) reaching 'very unhealthy' levels as of April 23. This follows a period of improved air quality after rainfall, but conditions have deteriorated, raising concerns about public health. The AQI had reached 247 on Tuesday morning which is above the threshold that is considered unhealthy.

According to the Air Quality Index (AQI), an AQI between 201 and 300 is considered ‘very unhealthy’. The Director General of the Department of Environment, Gyan Raj Subedi attributes the rise in pollution to a combination of factors, including insufficient rainfall, increasing drought, the burning of agricultural residues, and wildfires. Subedi noted that the lack of rainfall has contributed to the build-up of dust and smoke in the atmosphere.

Authorities are being urged to implement effective measures for sustainable and environment-friendly development, Subedi stated. Meanwhile, Binu Maharjan, a meteorologist at the Department of Hydrology and Meteorology, has indicated that there is no expectation of significant rainfall in the next three days, with temperatures expected to continue rising. "The atmosphere will not be clean until rainfall which helps increase pollution," added Maharjan.

The rise in pollution poses significant health risks, particularly for vulnerable groups such as children, senior citizens, and individuals with heart or respiratory problems. Experts advise residents to limit unnecessary outdoor activities and to wear masks when outside. This is a common problem yearly in Kathmandu.

For the Nepali diaspora, this news is concerning as many have family and friends residing in Kathmandu. The deterioration in air quality directly impacts their loved ones' health, potentially leading to respiratory issues and other health complications. Many members of the diaspora regularly travel back to Nepal, as well, becoming personally affected.

Staying informed about air quality levels in Kathmandu is crucial for diaspora members. Monitoring the AQI allows them to advise family members on necessary precautions, such as using air purifiers, wearing masks, and limiting outdoor exposure during peak pollution hours. This knowledge facilitates informed decision-making regarding travel and potential support for local initiatives.
