Nepal’s smoky mountains

A series of photographs of Kathmandu Valley taken by Abhushan Gautam on 10 May 2020, and on 6 April 2021 from the same spot in Chobar at the same time just before sunset.

After all traffic in Nepal and India came to a halt during the coronavirus lockdown last year, photographer Abhushan Gautam posted proof that if the air was clear enough, Mt Everest could be seen from Kathmandu.

On Tuesday, he went back to the exact spot in Chobar from where he had taken the photograph last year at 5-6PM just before sunset. The visibility was less than 2km.

“Last year, I was super excited to document the panoramic views of Kathmandu with the Himalayan backdrop,” Gautam recalls. “I did not feel like leaving the spot till nightfall.”

This year, with wildfires continuing to burn across Nepal, the country has been shrouded in thick smoke for more than two weeks. After some rain on 2 April, there had been a short respite, but Kathmandu’s Air Quality Index has gone back to above 300 for the past five days.

“This year, the poor visibility felt both alarming and suffocating because of the smoke, I just took the photographs and left the spot,” Gautam told Nepali Times.

With no references of mountains in the backdrop, Gautam missed some of the vantage points where he had stood last year. The air was so bad, the city had disappeared and only some of the high-rise apartments in Jhamsikhel were faintly visible through the dirty yellow haze.

“Capturing the panoramic images seemed seamless last year, the camera easily focused on Kathmandu landmarks and mountains beyond due to clear weather and soft light from the golden hour, this year the camera struggled to find those landmarks, and taking the panorama was even more difficult because I could not identify the common frames for stitching later,” he said.

The results can be seen in the before-and-after images: photographs last year were crisp and saturated, but this week they are blurry and dull.

The reason the air quality has remained so poor for so long is that there are thousands of fires right across western and central Nepal, as well as parts of Uttarakhand in India. Deficient precipitation in winter and spring had turned the forest underbrush dry, making this year’s fire season the worst in living memory.

There have been years like the winter of 2008-2009 when there were huge fires in the high mountains blowing plumes of smoke over Kathmandu. But these lasted only a few days after the rains arrived.

The Department of Meteorology and Hydrology says there are no signs of a major westerly system to bring rain or to blow the smoke away. There have also not been local convection systems along the mountains during this spring’s storm season so far.

The scale of the blazes is too extensive for local firefighters, and there has been no effective national effort to douse the flames. This means the fires are likely to continue until they burn themselves out.
