BBCI grew up in Nepal’s capital watching the Himalayas. Ever since I left, I’ve missed sweeping, panoramic views of a few of the highest mountain peaks on Earth.
Every time I go to Kathmandu, I hope to catch a glimpse of the dramatic mountain vary. However today, there’s often no luck.
The principle wrongdoer is extreme air air pollution that hangs as haze above the area.
And it is taking place even throughout the spring and autumn months, which as soon as provided clear skies.
Simply final April, the worldwide flight I used to be in needed to circle within the sky practically 20 occasions earlier than touchdown in Kathmandu, due to the hazy climate impacting visibility on the airport.
The lodge I checked in at was at an affordable peak from which mountains are seen on a transparent day – however there was no such day throughout my two-week keep.
Even from the main vantage level of Nagarkot, simply exterior Kathmandu, all that could possibly be seen was haze, as if the mountains didn’t exist.
“I not model the place for views of ‘dawn, sundown and Himalayas’ as I did up to now,” mentioned Yogendra Shakya, who has been working a lodge at Nagarkot since 1996.
“Since you possibly can’t have these issues largely now due to the haze, I’ve rebranded it with historical past and tradition as there are these tourism merchandise as properly right here.”
Throughout an earlier journey a 12 months in the past, I used to be hopeful I might be capable to see the mighty Himalayan peaks on a trek within the mesmerising Annapurna area – however had hardly any luck there both.

Scientists say hazy circumstances within the area have gotten more and more intense and lasting longer, lowering visibility considerably.
Haze is fashioned by a mixture of pollution like mud and smoke particles from fires, lowering visibility to lower than 5,000m (16,400ft). It stays stagnant within the sky throughout the dry season – which now lasts longer as a result of local weather change.
June to September is the area’s wet season, when Monsoon clouds slightly than haze preserve the mountains coated and visibility low.
Historically, March to Might and October to November have been the very best occasions for enterprise as a result of that was when skies remained clear and visibility was greatest.
However with rising temperatures and a scarcity of rain, and worsening air air pollution, the spring months are actually seeing thick haze with low visibility. These circumstances are starting as early as December.
‘No sighting means no enterprise’
Fortunate Chhetri, a pioneering feminine trekking information in Nepal, mentioned hazy circumstances had led to a 40% lower in enterprise.
“In a single case final 12 months, we needed to compensate a gaggle of trekkers as our guides couldn’t present them the Himalayas because of the hazy circumstances,” she added
An Australian vacationer who has visited Nepal greater than a dozen occasions since 1986 described not seeing the mountains as a “main let-down”.
“It wasn’t like this 10 years in the past however now the haze appears to have taken over and it’s terribly disappointing for guests like me,” mentioned John Carrol.
Krishna KC, the provincial chair of the Trekking Brokers Affiliation of Nepal within the western Gandaki province, says the trekking trade is in serious trouble.
“Our member trekking operators are getting depressed as a result of no sighting of the Himalayas means no enterprise. Lots of them are even contemplating altering professions,” he instructed the BBC.
Fortunate ChhetriOn the Indian aspect, close to the central Himalayas, hoteliers and tour operators say haze is now denser and returns faster than earlier than.
“We now have lengthy dry spells after which a heavy downpour, in contrast to up to now. So with rare rain the haze persists for for much longer,” mentioned Malika Virdi, who heads a community-run tourism enterprise within the state of Uttarakhand.
Nevertheless, Ms Virdi says vacationers are persistent – with many who did not catch the mountain vary returning to attempt their luck once more.
The western Himalayas in Pakistan have been comparatively much less affected by the haze as a result of the mountains are comparatively removed from cities.
However locals say that even the ranges that have been as soon as simply seen from locations like Peshawar and Gilgit are sometimes not seen.
“The sheet of haze stays hanging for an extended interval and we do not see the mountains that we may up to now,” mentioned Asif Shuja, the previous head of Pakistan’s environmental safety company.
Hazes and dirt storms growing
South Asian cities repeatedly prime lists of locations with highest ranges of air air pollution on the earth.
Public well being throughout the area has been badly impacted by the poisonous air, which incessantly causes journey disruption and faculty closures.
Vehicular and industrial emissions, mud from infrastructure building and dry gravel roads in addition to the open burning of waste are main sources of air air pollution year-round.
That is compounded by soot from huge forest fires – that are growing as a result of an extended dry season – and the burning of crop residues after the harvest by farmers in northern India, Pakistan and Nepal.
Climate circumstances holding hotter air above cooler air entice these pollution and restrict vertical air motion – stopping air pollution from dispersing.
“Hazes and dirt storms are growing in South Asia, and this development is projected to proceed as a result of local weather change and different elements,” Dr Someshwor Das from the South Asia Meteorological Affiliation instructed the BBC.
In 2024, the variety of hazy days recorded on the airport in Pokhara, a serious tourism hub in western Nepal, was 168 – up from 23 in 2020 and 84 in 2021, in response to Nepal’s division of hydrology and meteorology.

Consultants consider the Himalayas are in all probability the worst affected mountain vary on the earth given their location in a populous and polluted area.
This might imply the scintillating view of the Himalayas may now largely be restricted to images, work and postcards.
“We’re left to do enterprise with guilt once we are unable to indicate our shoppers the mountains that they pay us for,” mentioned trekking chief Ms Chhetri.
“And there may be nothing we are able to do in regards to the haze.”
