On a recent morning students at Darbar High School in the centre of Kathmandu were gathering for morning assembly. Excited chatter rose above the din of traffic outside the school gate.&nbsp; Nearby, pollution monitoring equipment found the concentration of suspended particulate matter smaller than 2.5 microns (PM2.5) in the school that morning at 211µg/m3. Inside classrooms, the monitor read 126µg/m3 on average all day. &nbsp; “I get at least three pupils every day with lung problems, it is worse in winter,” says Bhavna Ojha Joshi, a nurse at the school infirmary. <div class="embed-block"><iframe src="https://school-circle-eng.netlify.app/" style="border:0px #ffffff none;" scrolling="no" frameborder="0" marginheight="0px" marginwidth="0px" height="850px"width=100%></iframe></div> Nepal’s National Ambient Air Quality Standard considers PM2.5 concentration of 40µg/m3 in 24 hours as ‘healthy’. But the World Health Organization says it must not exceed 15µg/m3 , and says anything over this is unsafe. At the adjacent Ratna Park measuring station, the Air Quality Index (AQI) that morning was 179µg/m3 . Darbar High School is 123 years old, and collapsed in the 2015 earthquake. It has been rebuilt and is located at the busiest intersection in the city centre. All day long, students here breathe poisonous air that affects their health, learning ability, and physical and mental growth. Six km away at the northwest corner of the Ring Road, students are also gathering for morning assembly at the Shree Kali Devi Secondary School. The PM2.5 concentration there measured 89µg/m3, and it dropped to 35µg/m3 during the course of the day since vehicular emission is blown away by afternoon breeze from the west. &nbsp;&nbsp;&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240605070632_a7ca0bc091c99dfc5fcbeaed2f29ba7ed7d99a3e9828ad4890d17444e0dfcac0.jpg" data-media-id="editor_1" data-image-id="20240605070632_a7ca0bc091c99dfc5fcbeaed2f29ba7ed7d99a3e9828ad4890d17444e0dfcac0" data-rendition-name="original" width="1500" height="1000" loading="lazy" alt="Air pollution in schools NT"> </figure>  It is not just diesel and petrol cars, smoke from wildfires burning out of control all over Nepal made Kathmandu the most polluted city in the world in the IQAir list for several days in a row in April. Kathmandu ranked 11th in a list of 114 capital cities with the worst air.&nbsp; Diesel exhaust, smoke and dust are visible, but suspended particles smaller than 2.5 microns are most dangerous since they can cross the blood-air barrier in the lungs. &nbsp; “The particles enter the bloodstream and affect vital organs,” says infectious disease specialist Anup Subedee. Toxic air is harmful to all, but especially for children and the elderly. Because their lungs, brain, &nbsp;organs, and immune systems are still developing, children have weaker immune systems and are &nbsp;more affected by air pollutants.&nbsp; <div class="embed-block"><iframe src="https://schools-box-dots-eng.netlify.app/" style="border:0px #ffffff none;" scrolling="no" frameborder="0" marginheight="0px" marginwidth="0px" height="500px"width=100%></iframe></div> Moreover, while people over 18 breathe up to 20 times a minute, younger ones breathe 30 times, absorbing more particles. Pollutants also cause allergic reactions in the respiratory tract, which change the structure of their airways, causing chronic asthma. &nbsp; “Continuous exposure to toxic air in children is not limited to colds, headaches and shortness of breath, but can extend to chronic heart and lung disease as well as cancer,” warns paediatrician Ganesh Kumar Rai, former director of Kanti Children’s Hospital.&nbsp; At Tarun Secondary School, 500m outside Balaju on Kathmandu’s Ring Road, the PM2.5 concentration was 155µg/m3 in the morning as fifth grader Pramisa Bardeva was walking to school along a dusty road. She has a chronic cough, and wears a flimsy mask. &nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240605070632_0c11d1ac6472d965eb55fd9277b96f812482ce850aa296f59c33450e42b0a3ee.jpg" data-media-id="editor_3" data-image-id="20240605070632_0c11d1ac6472d965eb55fd9277b96f812482ce850aa296f59c33450e42b0a3ee" data-rendition-name="original" width="1356" height="830" loading="lazy" alt="Air pollution in schools NT"> </figure>  “My daughter’s studies have suffered because she is sick so often,” says Pramisa’s mother Manju. “They say she is sick because of the dirty air, and the hospital bills are piling up.” There are some 650,000 school-going children in Kathmandu Valley, of which 362,000 are students below Grade Five. Kathmandu has 1.6 million vehicles of which 80% are motorcycles. Most of these ply within the Ring Road, which means nearly 200,000 of the youngest students are exposed to the worst pollution all day at school. In 2023, the Ratna Park monitoring station recorded that only 8% of days are ‘clean air’ days, mostly during the monsoon. Environmental scientist Uttam Babu Shrestha returned to Nepal with his family from Australia four years ago. His son, now seven, has chronic asthma. “Although we worried about his health, his respiratory issues worsened after we came back due to the pollution here,” says Shrestha. His son has to regularly use an inhaler. Paediatricians said that a quarter of the children they see have asthma, whereas 20 years ago the most common ailments used to be diarrhea or typhoid.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240605070632_cf0f13b67c446bb47f8cf039d4bd5a6cff509833011a2d242a0ac6d7f103ce39.jpg" data-media-id="editor_4" data-image-id="20240605070632_cf0f13b67c446bb47f8cf039d4bd5a6cff509833011a2d242a0ac6d7f103ce39" data-rendition-name="original" width="1500" height="1000" loading="lazy" alt="Air pollution in schools NT"> </figure>  Data from Kanti Children’s Hospital shows that 38% of the 2,378 patients admitted in 2022-23 &nbsp;suffered from respiratory diseases. Another 2,951 children were treated in the pulmonary ward in that time. This year, nearly the same number of children had been in the pulmonary ward by February. &nbsp; Jagat Jeevan Ghimire, a physician at Kanti, specialises in children’s respiratory issues and estimates that one out of five children in Kathmandu Valley has a respiratory disease. Eight out of 12 ICU beds in the hospital are occupied by respiratory patients. Binod Sapkota’s three-year-old son Arogya suffers from asthma and has to use an inhaler up to four times a day. The asthma flares up when pollution levels are high. Physicians do not recommend mask use for children under five because it makes it difficult to tell if a child is having breathing issues. <div class="embed-block"><iframe src="https://schools-locator-eng.netlify.app/" style="border:0px #ffffff none;" scrolling="no" frameborder="0" marginheight="0px" marginwidth="0px" height="800px"width=100%></iframe></div> Air pollution kills more people than all other natural and manmade disasters in Nepal every year. Last year, an estimated 42,100 people died of respiratory issues. Toxic air cuts 4.6 years off the average Nepali’s lifespan, in the Tarai the figure is a shocking minus 7 years. Most physicians we spoke to said that the real culprit is the lack of political will in government to control emissions. Politicians seem not to have grasped the scale of this crisis, and that it is a life-or-death issue for so many Nepalis. &nbsp; Paediatrician Prashant Prasad Rijal notes how respiratory issues like pneumonia and asthma among children decreased during the Covid-imposed lockdowns, from up to four patients every day to four every month. “As soon as the pollution level dropped, the children were healthier,” he recalls. <div class="embed-block"><iframe src="https://schools-line-eng.netlify.app/" style="border:0px #ffffff none;" scrolling="no" frameborder="0" marginheight="0px" marginwidth="0px" height="750px"width=100%></iframe></div> The number of registered vehicles in Nepal has doubled over the last five years, while petroleum consumption has increased by 160% in the last decade. The major contributors to Kathmandu’s toxic air are vehicular and industrial emissions, brick kilns, development construction, crop and garbage burning, wildfires, and transboundary pollution. Studies show that emissions from substandard and old vehicles are the major cause of air pollution in Kathmandu. Vehicles need to pass an annual emission test, but only 30% of the total four wheelers took the test last year. &nbsp;Motorcycles do not need to undergo tests even if they emit poisonous gases. &nbsp; Garbage and agricultural waste burning is another contributor to toxic air in urban Nepal, even though it is prohibited by law. The National Statistics Office's 2022 study showed that 1 million tons of waste is produced annually in the country’s municipalities, of which 22,750 tons (2.2%) are incinerated. The National Agricultural Census 2022 found that 3 million tons of agricultural residue is burned every year, 90% of it in the Tarai. <div class="embed-block"><iframe title="No Day Free from Pollution" aria-label="Range Plot" id="datawrapper-chart-PhVXB" src="https://datawrapper.dwcdn.net/PhVXB/2/" scrolling="no" frameborder="0" style="width: 0; min-width: 100% !important; border: none;" height="371" data-external="1"></iframe><script type="text/javascript">!function(){"use strict";window.addEventListener("message",(function(a){if(void 0!==a.data["datawrapper-height"]){var e=document.querySelectorAll("iframe");for(var t in a.data["datawrapper-height"])for(var r=0;r<e.length;r++)if(e[r].contentWindow===a.source){var i=a.data["datawrapper-height"][t]+"px";e[r].style.height=i}}}))}(); </script></div> Pre-monsoon forest fires also make air pollution worse. NASA MODIS satellite recorded 4,114 wildfires during the first four months of 2024, double the previous years. The Cabinet four years ago formed the Kathmandu Valley Air Quality Management Action Plan to reduce vehicular emissions, stop waste burning, and use filters in diesel-powered vehicles. Nothing was done. The Ministry of Forests and Environment introduced standards to regulate brick kilns in 2018, but failed to monitor compliance.&nbsp; On 28 May, the finance minister increased taxes on petroleum products, but the money is not invested in reducing pollution or promoting clean energy. Electrification of public mass transport is the surest way to clean up Kathmandu air quickly, and reduce petroleum imports. But the new budget raised taxes on electric vehicles.&nbsp; Clean air is a Constitutional right of Nepalis, but Tek Bahadur Bogati, who moved to Kathmandu from Okhaldhunga, constantly worries about his son whose studies have suffered because of frequent hospitalisation which has drained the family’s savings.&nbsp; Says Bogati: “They told me it was due to dirty air, but where in Kathmandu is it clean?” This story was produced under an Earth Journalism Network (EJN) fellowship in collaboration with the Center for Data Journalism Nepal (CDJN).

Poisoning children at school

On World Health Day on 7 April this week, the Air Quality Index (AQI) in Kathmandu exceeded 300 – one of the dirtiest in any city in the world. Breathing was literally <a href="https://nepalitimes.com/banner/breathing-is-hazardous-to-health">lethal</a>.
Although the main source of pollution this week was smoke from brushfires raging across the country, emissions from diesel and petrol vehicles are a bigger year-round source of hazardous suspended particles and toxic gases.&nbsp;
The good news is that the sale of electric four-wheelers is growing rapidly, and battery-powered vehicles now account for one-third of Nepal’s total car imports. Outside Kathmandu, vans, microbuses and three-wheelers are switching to electric as never before
All this has happened even though there is still a hefty <a href="https://nepalitimes.com/news/1-step-forward-2-steps-back-in-nepal">tax on battery-powered vehicles</a>. In last year’s budget ex-Finance Minister Prakash Mahat increased the tax on smaller EVs and electric vans while inexplicably reducing the tax on luxury SUVs.
This year, all eyes are on the new Finance Minister Barsha Man Pun, who is under pressure to raise government revenue that has fallen drastically due to a slowdown in imports. Instead of lowering taxes and even announcing subsidies on electric cars and appliances, he may actually increase them. He could also do it selectively to favour certain EV brands imported by cronies.
“The government should be more careful in how it taxes electric vehicles,” says air pollution activist Bhushan Tuladhar who is also the director of Sajha Yatayat, the public transport company that is operating 40 electric buses. “It should be consistent, predictable and guided by science, it can’t be a kneejerk reaction with no real planning.”
One large electric bus can replace at least 10 cars, easing road congestion, improving air pollution and reducing petroleum imports. But existing excise and import taxes make battery-powered buses up to five times more expensive than a diesel bus of similar capacity.&nbsp;
On Tuesday, <a href="https://nepalitimes.com/news/sajha-s-green-buses-go-greener">Sajha Yatayat inaugurated Nepal’s largest charging station</a> with 24 charging points where it will charge its 40 e-buses. Speaking at the event, Kulman Ghising of Nepal Electricity Authority (NEA) acknowledged that Nepal was undergoing a “massive transport transition”.&nbsp;
“We will soon have surplus power even in winter, and private EVs can only use so much of our electricity, what we really need is to electrify our mass transport,” he said. “On one hand, by increasing our consumption of electricity, it will reduce our petroleum imports and subsequently our trade deficit. It will also help us meet our net zero target. This is also very feasible as a business model.”
Petroleum imports account for one-fourth of Nepal’s total imports and is more than all of our exports combined. Reducing petroleum consumption by just 10% would save the country over Rs30 billion whereas even exporting all of our current power generation of 3,000MW would earn us just half that amount.
It is simple maths: prioritising <a href="https://nepalitimes.com/multimedia/missing-pieces-of-the-hydropower-jigsaw">domestic electricity consumption</a> is a win-win-win for the country. Electrification of industries, tourism and agriculture would also mean tens of thousands of new green jobs and help stem the mass exodus of youth.&nbsp;
A policy decision is also urgently needed for electric taxis. Bagmati Province does not register new battery-powered cabs, but they are still being imported as private cars which then buy number plates of the older taxis. This means the electric taxis have to pay higher road taxes, keeping their fares high.
A battery-powered taxi can be fully charged for just Rs106, and will have a range of 180km. A petrol taxi would need Rs3,500 worth of petrol to cover that distance.&nbsp;
Climate expert Manjeet Dhakal says that budget fluctuations make people and investors lose confidence, and this is especially important ahead of the Nepal Investment Summit later this month.
“At a time when the whole world is moving towards clean energy, Nepal’s contradictory policy regarding EV sends out the wrong message to the business community,” he adds. “But at the next &nbsp;budget, we must incentivise electric buses. Even within the EV bracket, this is the segment we have to hit had if we are to make a real difference.”
Without state subsidy and support, the private sector is unlikely to expand on electric facilities. Pollution tax can very well come in handy here if there is a political will.
Even then EVs are just a part of an ecosystem, we need charging infrastructure, skilled human resources for the new technology, and policies that promote them.
Similarly, two-wheelers make up nearly 80% of total vehicles in Nepal. But there are electric bikes and scooters, government and the private sector have much to do to increase consumer and market confidence in them.
Consecutive governments have been flip-flopping tax rates on electric vehicles in recent years. In 2020, <a href="https://nepalitimes.com/news/nepal-reduces-tax-on-electric-cars">the government reduced the taxes on battery-powered vehicles</a>. A year later, it re-imposed tax for electric SUVs while cheaper vehicles were still taxed less. Last year, the tax on smaller EVs and electric vans was increased while that on luxury SUVs was slashed.
Not long ago a former finance minister was caught questioning how the government would earn its revenue if it didn’t tax electric vehicles. Such is our policymaking that we rely on imports to generate income for the government when in fact revenue should be based on local industries and goods.
“Financial policy is based on politics and that is the sad reality, more so now with coalition governments,” says Tuladhar. “But even then, taxation should not be a long-term policy. But unfortunately, people who are making policies aren't riding buses &nbsp;so they have no interest in public transport or don’t even know what to do with it.”

Photo: GOPEN RAI</figcaption></figure>Bhaktapur used to be a town where people from Kathmandu went to get away from it all, for a quieter place and fresh air.No more. Khwopa, as the historic town is known in Newa, has consistently recorded some of the worst air quality in Kathmandu Valley, outranking even the industrial belts of Biratnagar and Bhairawa.A recent Air Quality Index (AQI) measurement of 22 sites in Kathmandu Valley found Bhaktapur to have the most hazardous concentrations of suspended particles below 2.5 microns (PM2.5), aerosols and toxic gases. On 8 February, Madhyapur Thimi recorded the highest AQI at 310 closely followed by Duwakot at 296 and Sallaghari at 279. Changunarayan registered 234, Tathali 234 and Ghyakhel 246.Elsewhere in Kathmandu on that day, the AQI count was still dirty at 181, but much lower than Bhaktapur. Pokhara recorded 143, Birganj 131, Chitwan 69, Nepalganj 71, Biratnagar 85 and Hetauda 81 on 8 February.The World Health Organisation (WHO) considers AQI up to 50 to be good, up to 100 as medium, 100-150 bad, 151-200 unhealthy, 201-300 very unhealthy and above 300 hazardous.Read also: <a href="https://www.nepalitimes.com/banner/high-and-dry/">High and dry</a>, Ramesh KumarAs for the PM2.5, the WHO maintains that concentration has to be below 25µg/m³ to be healthy for humans. But even in mid-February with winter almost over, the PM2.5 in Bhaktapur on 21 February was 25 times higher than the WHO annual air quality guideline value.“During winter, the inversion phenomenon traps polluted air at ground level,” says pollution specialist Bhupendra Das. “It is still winter and the fact that there has been no rain has meant that Bhaktapur’s pollution has nowhere to go.”Indeed, much of Nepal has not had any rainfall since mid-October 2022. Kathmandu valley alone should get about 95mm of rain between mid-October to mid-February but this dry spell has meant that there has been no precipitation to wash down the pollutants. Smoke from early wildfires across the country has added to the problem.But the reasons why Bhaktapur has the worst air quality has more to do with prevailing winds blowing all of Kathmandu's vehicular emissions and other pollutants to the eastern rim of the Valley where it is blocked by the hills.Read also: <a href="https://www.nepalitimes.com/banner/hefty-fines-fail-to-deter-polluting-vehicles/">Hefty fines fail to deter polluting vehicles</a>, Sushila Buhathoki <figure><img width="1133" height="960" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20230228150240/63fe125f9c7e80680e0da51cjpeg.jpg" alt=""><figcaption> </figcaption></figure>In addition, most of the Valley’s brick kilns have relocated to the outskirts of Bhaktapur where they spew out black smoke from coal and other fuel into the already polluted air.Says Regina Maskey of the Central Department of Environment at Tribhuvan University: “The prevailing westerlies are transported over Bhaktapur, where they are trapped.”Dirty air consists of several different types of pollutants including particulate matter made up of smoke, soot, dust, and poisonous gases like carbon monoxide and ozone from two-wheelers. Then there is open burning of agricultural residue and garbage.On top of all this, there is the cross-border pollution from the north Indian plains which researchers say can constitute up to 40% of the pollution in Kathmandu Valley in winter.Read also: <a href="https://www.nepalitimes.com/banner/kathmandus-toxic-trash/">Kathmandu’s toxic trash</a>, Sonia AwaleBut brick kilns are perhaps the biggest culprits for Bhaktapur. There are 60 registered brick kilns in the town, with 40 of them currently operating. Most of them are right outside the densely populated old town.After nearly three years of stoppage due to the Covid-19 crisis and subsequent decline in construction, the kilns are back in operation to fulfil pent-up demand. Only a few kilns have begun to replace coal with less polluting biomass pellets because of coal prices going up after the Russian invasion of Ukraine.Ultimately, there is no alternative but to opt for alternatives to fired bricks like cement blocks or compressed stabilised earth bricks (CSEB). Stricter control of polluting diesel buses and trucks entering and exiting the Valley through the busy Sanga pass and a conversion to electric public transport would also help.Reducing Nepal's petroleum import from India by only 10% will save us more than Rs30 billion a year. This money along with a seizable pollution tax in our reserves can help incentivise electric mass transit for Nepal, if there was a political will to do so.Read also: <a href="https://www.nepalitimes.com/opinion/nepalis-do-not-have-to-breathe-dirty-air/">Nepalis do not have to breathe dirty air</a>, Shreesha Nankhwa <figure><img width="2048" height="1366" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20230228150240/63fe12629c7e80680e0da51djpeg.jpg" alt=""><figcaption> </figcaption></figure>Worsening air pollution also has consequences on visibility. All of February, the air quality in Kathmandu Valley has been so bad that flights into the airport have had to hold for landing clearance, leading to delays.“Lack of visibility has made it difficult for flights, which is a serious problem,” says Das, adding that while new technology has been adopted to reduce the smoke, there has been no innovation to remove sulphur dioxide emissions from low-grade coal used in brick kilns.Given the hazardous levels of air pollution in the cities, the government back in 2020 issued the Air Quality Management Action Plan for Kathmandu Valley with a provision for a state of emergency to be declared when the AQI exceeds 300. But AQI exceeds 300 most mornings in Bhaktapur with no action from either the national government or the municipality.Research has shown that the average life expectancy of Kathmandu Valley residents has been reduced by four years due to air pollution. The figure is 7 years for people living in the Tarai across the Indian border.Read also: <a href="https://www.nepalitimes.com/here-now/solution-to-pollution/">Solution to pollution</a>, Pallavi Pant and Anobha GurungIn 2019, 17,800 deaths in Nepal were attributed to PM2.5 by the State of Global Air report. From 2010-2019, nearly 150,000 lives have been lost across the country due to respiratory ailments caused by worsening air pollution.Air pollution causes a wide range of chronic health problems including but not limited to heart attack, cardiac arrest, pneumonia, bronchitis, lung cancer, breathlessness, diabetes, mental health disorders and congenital issues.According to the WHO, more people have lost their lives to air pollution than the Covid-19 pandemic which has killed over 6.7 million people globally since 2020. Comparatively, air pollution killed 9 million people in just one year in 2019. And yet, there is not much effort into reducing the impact of air pollution or serious measures to reduce the emissions and save millions of lives.The report also stated that the concentration of PM2.5 in Nepal was as high as that in Indian cities which often make it to the most polluted list. Kathmandu and Tarai cities often make it to the list too. What is surprising is that Bhaktapur municipality has been a stronghold of the Nepal Workers and Peasants Party which has been known for good governance, and for service delivery in education and health.It is time the federal and provincial governments worked with Kathmandu Valley mayors to clean up at least the vehicular emissions and open garbage burning that is disproportionately affecting Bhaktapur. And Bhaktapur itself could ban brick kilns so close to its town centre.  Read also:<a href="https://www.nepalitimes.com/banner/warning-breathing-is-hazardous-to-health/">WARNING: Breathing is hazardous to health</a>, Sonia Awale

But Das suggests a lowering of the present upper limit of 20 years to 15 with emphasis on strict monitoring of older vehicles for emissions.Read also: <a href="https://www.nepalitimes.com/banner/how-weather-elevates-air-pollution-in-kathmandu/">How weather elevates air pollution in Kathmandu</a>, Jagdishwor Karmacharya and Shanti Kandel“Because this study covers both the historical emission factors as well as recent ones, it is valuable for the development of an emission inventory for India and other countries in the South Asia region,” says Gautam. “What is needed is a scaled-up project covering the whole region.”Previous studies, such as one <a href="https://aaqr.org/articles/aaqr-19-03-achr-0159">published in 2020</a> in Aerosol and Atmospheric Chemistry, had also shown that poor quality fuel, high traffic congestion, old and poorly maintained diesel vehicles were responsible for a large increase in transport-related emissions in recent years.The 2020 study found that timely servicing and maintenance of diesel vehicles could lower black carbon emission by 1.4 times and PM 2.5 by almost three times. It recommended a <a href="https://www.scidev.net/asia-pacific/governance/policy/">policy</a> of mandatory, routine maintenance of the diesel fleet to systematically reduce emissions in the Kathmandu Valley.Read also: <a href="https://www.nepalitimes.com/latest/the-road-to-electric-transportation-in-nepal/">The road to electric transportation in Nepal</a>, Diya RijalDas suggests a different approach, however. “The present scenario in Kathmandu and in the rest of Nepal demands practical, cost-effective solutions to quickly cut emissions. These could start with repair and maintenance of roads, improvement of fuel quality and switching the ageing diesel fleet to at least Euro IV standards.”Nepal’s nationally determined contribution submitted to the <a href="https://www.unfccc.int/">UN Framework Convention on Climate Change</a> envisages promotion of advanced, electric, hybrid, hydrogen-powered, and other types of vehicles running on clean fuels. By 2025 at least 25% of all private passenger vehicles sales and 20% of all public transport vehicles will be electric-powered, the commitments say.“The concept of <a href="https://www.scidev.net/asia-pacific/environment/climate-change/">climate</a>-resilient economic growth through an improved transport sector is being taken seriously,” adds Das. “It is now inescapable that highly <a href="https://www.scidev.net/asia-pacific/environment/pollution/">polluting</a> and obsolete transport vehicles burning diesel be phased out through scrappage policies that involve compensations or other schemes with incentives for vehicle owners.”Read also: <a href="https://www.nepalitimes.com/here-now/cleaner-air-with-greener-buses/">Cleaner air with greener buses</a>, Bhushan TuladharThis piece was produced by SciDev.Net’s Asia &amp; Pacific desk.

‘Nepal must scrap old diesel vehicles’

<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110161156/636d1f909c7e80680e0af470jpeg.jpg" alt="" width="2000" height="2625"/><figcaption>Photo: AMIT MACHAMASI</figcaption></figure>On Thursday morning, Nepali Times photographer Amit Machamasi was greeted with a shocking sight when he drove up to Nagarkot to take pictures of overnight snowfall. Below him, dozens of <a href="http://archive.nepalitimes.com/news.php?id=2498#.Yc5xVy2B2t8" target="_blank" rel="noopener noreferrer">brick kilns</a> were spewing out smoke and steam into the city’s air (photo).The rain had washed down suspended particles, but the brick kilns were pumping more smoke into the air we breathe. There have been attempts to relocate brick kilns away from the densely-populated capital, but political patronage means owners are still fouling the air.After the 2015 earthquake damaged most of the Valley’s brick factories, <a href="http://archive.nepalitimes.com/article/nation/brick-factories-still-using-old-polluting-technology,2078" target="_blank" rel="noopener noreferrer">some adopted cleaner technology</a> to reduce emissions. Public pressure and urban growth then pushed most brick factories to the city’s fringes, and they are now  concentrated around Bhaktapur – most of those in the photograph are traditional dirty chimneys.After two years of forced closure during the pandemic, the brick kilns are once more working overtime to fill a backlog of demand from builders. But with politicians bogged down in power struggles, local leaders are too distracted to address the pandemic and pollution crises – both of which affect the human respiratory system.In a public opinion poll in this newspaper just before the 2017 elections, most respondents said <a href="https://www.nepalitimes.com/banner/dirty-politics-dirty-air/" target="_blank" rel="noopener noreferrer">air pollution</a> topped their list of concerns. Pollution has gotten worse since then, but it is unlikely that dirty air will figure in election speeches in 2022.“We have cleaner options like <a href="https://archive.nepalitimes.com/article/nation/earth-bricks-for-cleaner-and-healthier-kathmandu,4161" target="_blank" rel="noopener noreferrer">interlocking earth bricks</a>, so we just need public pressure to make it an election issue,” says environmentalist Bhushan Tuladhar.A pre-pandemic research showed that 40% of suspended particulates in Kathmandu’s air was from brick kilns, 30% from vehicular emissions, and 20% from open burning of trash and biomass. With the exponential increase in cars and motorcycles, the concentration of vehicular pollution at street level is now 70%.“<a style="letter-spacing: 0.01em;" href="https://www.nepalitimes.com/banner/breathing-is-hazardous-to-health/" target="_blank" rel="noopener noreferrer">Hazardous pollution levels</a> in winter have become the norm, yet the government is not doing much to control it,” says Shilshila Acharya of the Avni Centre for Sustainability. “The public should demand action from our leaders.”Although public awareness about <a href="https://www.nepalitimes.com/banner/how-weather-elevates-air-pollution-in-kathmandu/" target="_blank" rel="noopener noreferrer">air pollution</a> is at an all time high, it has not translated into action by municipalities or the federal government – even though in a democracy elections would be the way to force accountability from public officials.Says Tuladhar: “Campaigning in 2022 for elections, particularly for local government, will give us a platform to build political will to reduce air pollution. People have to be outraged, and the good news is that we have some young and educated leaders taking the lead.”In 2019, <a href="https://www.nepalitimes.com/banner/nepal-is-going-up-in-smoke/" target="_blank" rel="noopener noreferrer">air pollution</a> resulted in the deaths of 42,100 Nepalis, according to one research. Many more were indirectly affected. Vehicular emission, garbage and agricultural residue burning and brick kilns were the main sources of toxic ambient air.Besides shifting to cleaner and greener brick-making technology, controlling garbage burning, and a rapid transition to electric vehicles with government investment in electric mass transit, would be steps that would quickly improve air quality in Kathmandu.Air pollution is leading to the <a href="https://www.nepalitimes.com/latest/double-whammy-air-pollution-and-covid-19/" target="_blank" rel="noopener noreferrer">premature death of Kathmandu’s citizens</a>. It has a huge impact on the economy. The solution is political, and elected officials need to respond to the crisis.Adds Shilshila Acharya: “Politicians as always are big on promises but we demand that they first protect our health by cleaning up the air we breathe. It is a basic right guaranteed by the Constitution. Don't talk about more grandiose plans, just clean up our air first.”

Happy New Air

In addition, peak season mean 8-hr ozone concentration should not exceed 60 kg/m3. The 2005 guideline values for PM2 and NO2 were, 10kg/m3 and 40 kg/m3 respectively, with no recommendation for long-term suspended particles and ozone concentrations.Environmentalist Bhushan Tuladhar immediately took to twitter to respond to the new recommended standard for air quality: ‘The WHO just released its new air quality guidelines which have halved the guideline value for annual average PM2.5 in ambient air. This means Kathmandu, which had annual PM2.5 levels that were about five times higher than the WHO guidelines now have pollution levels that are 10 fold higher.’The new standards are ambitious and reflect the large impact of <a href="https://www.nepalitimes.com/editorial/polluted-politics/" target="_blank" rel="noopener noreferrer">air pollution</a> on public health, and experts hope that it will influence air quality policy across the globe. They recommend bold action to clean up the air at all levels and across all sectors such as transport, energy, industry, agriculture and residential.“Air pollution is a major global public health threat that causes a range of adverse health effects, even at the lowest observable concentrations. The updated guidelines offer a wake-up call, to reconsider current air quality legislation and regulations,” noted a joint statement released by the International Society for Environmental Epidemiology (ISEE) with the European Respiratory Society following the revised guidelines.It adds: “There is ample evidence to strongly support government action to reduce air pollution and address climate change simultaneously. But the most important message is that each reduction in the outdoor concentrations of key air pollutants brings health benefits to the surrounding population, even in places which already have low pollution concentrations.”Additionally, most jurisdictions with <a href="https://www.nepalitimes.com/here-now/solution-to-pollution/" target="_blank" rel="noopener noreferrer">clean air</a> regulations have relied on fixed limit values with little incentive to further reduce air pollution levels once compliance with the limit value is achieved. Given the evidence that health effects occur down to very low concentration levels, future clean air policies must include incentives for progressive lowering of exposures of the entire population, thereby improving health for all.The new <a href="https://www.nepalitimes.com/here-now/how-transboundary-haze-affects-nepal/" target="_blank" rel="noopener noreferrer">air quality</a> guidelines are not legally binding however but experts believe can represent a turning point in the way we approach air pollution globally, and in particular, South Asia where the air pollution levels are consistently high and the health burden is stark.“The new guidelines offer a benchmark for South Asian cities and countries to plan their air quality agenda. This will bring renewed interest in the topic and create an opportunity to push for stronger action,” says Pallavi Pant of Health Effects Institute based in Boston.She adds: “We know where we’d like to get to, and the real discussion now should be focused on the basket of strategies and sectors we need to address.”Air pollution, indoors and outdoors, accounted for some 12% of all death in 2019. Air pollution currently ranks fourth among major risk factors for global disease and mortality, only behind <a href="https://www.nepalitimes.com/latest/why-do-so-many-nepalis-have-high-blood-pressure/" target="_blank" rel="noopener noreferrer">hypertension</a>, smoking and dietary factors.In terms of economic burden, the estimated global health-related external costs were $5 trillion in 2013 with an additional $225 billion in lost labour productivity as per the World Bank Group 2016.Here in Nepal, the new guidelines hardly made it to the news. Nepal doesn’t even have a minister for the environment because of a continued political stalemate.Successive governments in the recent past have made commitments to promote <a href="https://www.nepalitimes.com/here-now/cleaner-air-with-greener-buses/" target="_blank" rel="noopener noreferrer">electric vehicles and transport for clean air</a>, but they have done the opposite. Earlier this year in the budget, it reintroduced tax rebates. But only this week, Prime Minister Sher Bahadur Deuba’s government slashed taxes on the import of 10 or more diesel buses by new luxury hotels to 1%. It also cut by half the duty on petrol motorcycle assembly in Nepal.The Covid-19 pandemic and subsequent lockdowns over the last two years have shown people that the <a href="https://www.nepalitimes.com/banner/nepal-lockdown-proves-air-quality-can-be-improved/" target="_blank" rel="noopener noreferrer">goal of clean air can be achieved</a>, and it has become even more crucial at this point where the coronavirus cases are going down, vaccinations have picked up and businesses are reopening for the Dasain-Tihar festive season.“There is no shortcut to clean air, we need long-term policies that target major sources including transportation, use of wood/animal dung for cooking and heating, brick kilns, coal power plants, industries and waste burning,” adds Pant ,who is from India.She adds: “Access to clean energy for all is one key policy that can help reduce the burden of air pollution. It is also useful to keep in mind that air pollution is a multi-sectoral problem, and we must engage not just technical experts but also legal and policy experts, economists, healthcare workers and others in developing solutions.In the short term, especially as we approach the winter season, the government should ensure the public that <a href="https://www.nepalitimes.com/here-now/open-air/" target="_blank" rel="noopener noreferrer">air quality data</a> is accessible and understandable. With this information, the public can avoid outdoor activities during hours when the pollution is at its peak and reduce the prevalence of allergies and immediate respiratory illness.

Previous wildfires in 2008 and 2012 in Rasuwa and Nuwakot had also turned the sky dark over Kathmandu, but only briefly. What worries them is the extended nature of the current spate of fires that has now lasted five months, and continues to get worse.They say the main reason for this year’s disaster is the extended winter drought, with precipitation over Central Nepal at only 10% of normal, and the dry spell continuing into spring. Scientists are reluctant to make a direct correlation between climate crisis and individual weather events, but studies have shown that climate-related droughts did contribute to last year’s devastating fires in California and Australia."Spring rainfall varies year to year. Last year we had a relatively wet spring. This year is exceptionally dry with forest fires already in January," says Arnico Panday, an atmospheric scientist and senior research fellow at the Institute for Integrated Development Studies (IIDS). "While it is difficult to immediately connect specific events to climate change, which considers average change over decades, there is an expectation that climate change will bring more extreme dry and wet events even if total precipitation stays the same.”There could be other factors at play like accumulated brush in the undergrowth because of the movement restrictions last year that added  flammable material to the forest floor. Spring is a season when many farmers deliberately light fires to encourage new shoots for their livestock to graze on, or before maize planting. These practices could have allowed fires to spread faster this year because the underbrush was already tinder dry.Depopulation of Nepal’s hinterland due to out-migration also means there are fewer people to make and maintain firebreaks in community forests, and also to extinguish local fires when they ignite. Forest management has historically also tended to be less responsive during periods of instability, especially when there is uncertainty over control over natural resources at the local level.https://youtu.be/tcbA-epQ6UoForest fires burning out of control in the mountains of Achham district on 10 March. Video: KUNDA DIXITIndeed, even the federal government’s response seem to be to let the fires burn themselves out. Despite the unprecedented scale of the blazes the Home Ministry has not mobilised the security forces and local authorities to take action. National Disaster Risk Reduction and Management Authority has so far only been counting the number of fires, and expressing concern.Besides addressing the immediate health concerns for millions of Nepalis who are <a href="https://www.nepalitimes.com/banner/dirty-politics-dirty-air/" target="_blank" rel="noopener noreferrer">exposed to hazardous air</a> for days on end, the government also has to start looking at minimising the damage during the annual fire season in future.<a style="font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/banner/wildfires-ravage-nepal-mountains/" target="_blank" rel="noopener noreferrer">This year’s wildfires</a> have received a lot of attention because Kathmandu and other cities were badly affected, but air quality experts say the cumulative impact of vehicular emission and industrial pollution throughout the year is much more harmful to health. There is also cross-border industrial pollution, smoke from crop residue burning, as well as wind-blown desert sand dust, which have been particularly acute in the past months.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/2022111012110/636cd9e89c7e80680e092eccjpeg.jpg" alt="" width="1500" height="745"><figcaption> </figcaption></figure><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/2022111012110/636cd9ec9c7e80680e092ecdjpeg.jpg" alt="" width="1500" height="743"><figcaption> </figcaption></figure>“This week’s forest fires just made the existing air pollution in Kathmandu worse, we should be doing a lot more to reduce vehicular exhaust, brick kilns and open garbage burning,” says Bhushan Tuladhar, a board member of Sajha Yatayat which last week opened a tender for 40 electric buses to upgrade Kathmandu’s urban transport system.And although Kathmandu got a bad name this weekend for topping the list of the <a href="https://www.nepalitimes.com/editorial/polluted-politics/" target="_blank" rel="noopener noreferrer">world’s most polluted cities</a>, experts say such rankings are misleading because they ignore other urban centres like Bharatpur or Simra where the air quality has been even worse for longer periods.“In the past couple of years, we have learnt that the absolute worst air quality in cities like Delhi, San Francisco, Sydney or Kathmandu is found when they are importing smoke from large nearby biomass fires,” explains Arnico Panday, who is also CEO of the Ullens Education Foundation. “Actually it is the vehicles and industries that have larger year-around emissions.”Meanwhile, meteorologists say there is no change in wind direction or rain forecast this week to blow away smoke, or douse the fires. Without any ground or aerial firefighting ability on the scale needed, it may just be that Nepal will have to wait for the fires to burn themselves out.

The pollution level had been stable or slightly below the daily average in the preceding days.Air pollution over an area is determined by emissions and their transport. Sources of pollution can be both local and remote, whereas it can be carried into and out of the area depending on its geographical setting and atmospheric condition.Understanding the role of geography and seasonal climatic variations in altering air pollution levels in Nepal has been generally well understood. The role of weather events in air pollution fluctuation is of key importance in predicting pollution levels across the country. Predicting weather therefore is closely related to predicting air pollution.Pollution forecasting a few days in advance has practical as well as policy implications. If pollution levels can be predicted a few days in advance, people can plan their activities accordingly. It also allows the government ample time to introduce temporary restrictions to reduce the severity of pollution during adverse weather conditions.The alarming levels of pollution in Kathmandu Valley in winter has been receiving much publicity, and has been a matter of <a href="https://www.nepalitimes.com/banner/dirty-politics-dirty-air/">serious concern</a>. The high pollution episode on 4-5 January got widespread publicity in the media, raising public awareness about the issue.Residents of Kathmandu already taking precautions against the Covid-19 pandemic were made conscious of the additional hazards of poor air quality on their health.As the PM2.5 AQI (the concentration of fine particles less than 2.5 microns in diameter) exceeded 600 at its peak in some areas of the Valley, the Department of Environment (DoE) issued a press release on 5 January, urging people to remain indoors as far as possible and refrain from making open fires. It was also advised that the high level of pollution could prevail for some time, depending on how weather impacted its diffusion.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110101152/636cca9d9c7e80680e08bb78jpeg.jpg" alt="AQI graph" width="719" height="541"><figcaption> </figcaption></figure>Research has shown that the lifespan of some Nepalis has been <a href="http://archive.nepalitimes.com/article/Nepali-Times-Buzz/air-pollution-decreases-life-span,3999">reduced by up to five years</a> because of the air we breathe. Advance knowledge of the situation would have been more useful for the public.Every time there is a discourse on Kathmandu’s <a href="https://www.nepalitimes.com/here-now/air-pollution-is-more-dangerous-than-smoking/">pollution situation</a>, experts flag their opinions citing the topography of the valley and winter inversion as the major factors that trap polluted air.In the case of the early January pollution event, however, the air pollution level decreased to pre-episode level from 6 January onwards, which promoted an analysis of the impact that cloud cover from a westerly front had on AQI.The daily and hourly time series of air pollution level and concentration of gases was recorded by air quality monitoring stations for the analysis. A newly established Department of Hydrology and Meteorology (DHM) monitoring station at Nagarkot as well as from other measurements in the valley were used. The vertical atmospheric profile measured by DHM’s radiosonde station at Kirtipur, satellite imagery and surface weather charts related to the first week of January were reference points.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110101152/636ccaa09c7e80680e08bb79png.png" alt="DHM’s Radiosonde station at Kirtipur" width="1600" height="342"><figcaption> </figcaption></figure>A comparison of the time series of high-frequency PM2.5 counts shows that hazardous air quality levels were recorded within the Kathmandu Valley in Bhaisepati, Bhaktapur and Ratna Park areas. These measurements were also compared to air quality in cities across Nepal.Air quality deteriorated to dangerous levels from the afternoon of 4 January till the morning of 6 January, whereas such counts were comparable to those recorded before and after the hazardous air level episode in Nepalganj, Dang, Pokhara, Hetauda.A comparison of AQI PM2.5 daily average time series shows that their values on 4 and 5 January is comparable with the values on preceding days at the same stations outside the valley, whereas it dropped by 30% or more on 6-7 January for Nepalganj, Dang, and Pokhara stations.However, the stations at Ratna Park and Bhaisepati recorded a 50% rise in pollution levels on 4 and 5 January, whereas the Bhaktapur station recorded only a 15% rise.In contrast, the Nagarkot station recorded better air quality by about 40% or more from 4-7 January. Similarly, the concentration of ozone, nitrous oxides, carbon monoxide and black carbon-8 (soot particles) also came down by about 10% or more in Nagarkot during the period compared to preceding days, which is consistent with the reduction of AQI PM2.5 there.It is worth noting that Nagarkot and surrounding regions on the eastern rim of the Valley are considered as the primary outflow region for wind-blown pollutants from inside the valley trough since upper-level wind is predominantly westerly across Nepal in winter. In fact, this was why the DHM selected Nagarkot as the site for establishing an air quality monitoring station.The differences in the daily average for the AQI PM2.5 count for the stations in the Valley and that at Nagarkot are of particular interest. The measurements for 4-6 January could mean that the stations could be valuable in enhancing our understanding of the variation of ambient air quality in the valley over time, and the transport of pollutants.Data from the radiosonde station at the premises of Tribhuvan University Kirtipur is being released regularly at 5:45AM since March 2019. Attached to a hydrogen balloon, the radiosonde measures temperature, relative humidity, wind speed and direction at different elevations and transmits the data to a ground station.Globally, there are hundreds of such stations that make measurements once or twice a day, synchronously providing valuable insight into the global weather pattern at different altitudes.Comparing the Kirtipur data on 1-5 January, there is a clear indication that ground-level inversion was present on both days. This happens when a layer of cold air is trapped by warmer air above it. Ground-level inversion occurs almost every day during winter in the Valley, and has the effect of concentrating overnight pollution.The stronger the inversion, and deeper and stronger the stable layer, which makes it harder for a parcel of air to rise as it will be relatively colder, hence denser, than its surrounding. Consequently, it is squeezed downwards.Hence, pollutants suspended in the bottom layer of the atmosphere are pretty much confined within the inversion layer. The shallower the depth of inversion, the higher is the concentration of air pollutants, even with the same amount of emission load, since they are confined in a smaller volume near the ground.On most days during the winter, ground-level inversion is gradually established in the Kathmandu Valley from the evening and intensifies in the night, but it weakens as it is burned away by the sun during the morning, disintegrating by noon. Once the inversion decays, the bottom layer of air mixes with the higher levels of the atmosphere, leading to lowering of air pollution level at the surface.In addition, as the wind picks up towards the afternoon, much of the air pollution is blown away to the east, leading to a reduction of the concentration of air pollutants in the Valley.However, from the afternoon of 3 January till the morning of 6 January, Nepal was under the influence of a westerly disturbance, and the most parts of the country were covered by high clouds (Figure 3) with light scattered precipitation in the western parts of the country.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110101152/636ccaa29c7e80680e08bb7ajpeg.jpg" alt="Satellite images of weather" width="1429" height="437"><figcaption> </figcaption></figure>The overcast condition, however, prevented the sun from dissipating the inversion and prevented the mixing of the lower atmospheric levels with upper layers over most parts of Nepal, including Kathmandu Valley.It can be inferred that the surface inversion did not fully disintegrate on those days though it would have been weakened and lifted slightly higher in the afternoon. This is also supported by the relatively calm winds recorded in the afternoons of 4 and 5 January, at Kirtipur and Khumaltar stations (Figure 5).<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110101152/636ccaa49c7e80680e08bb7bjpeg.jpg" alt="global solar radiaion" width="1414" height="365"><figcaption> </figcaption></figure><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110101152/636ccaa59c7e80680e08bb7cjpeg.jpg" alt="wind speed" width="1417" height="344"><figcaption> </figcaption></figure>Daily average AQI PM2.5 values in stations outside Kathmandu valley remained more or less stable from last week of December to 5 January, which goes to show that the higher concentration of PM2.5 in the Kathmandu Valley on 4-5 January was mostly contributed by the local sources. Moreover, the relatively lower levels recorded at Nagarkot station on the same days is likely due to confinement of pollutants within the valley.With the passage of western disturbance, the sky over Kathmandu Valley became clear from the early morning of 6 January. As a result, mixing of the bottom layer of air with the higher levels became possible, thus leading to subsequent dissipation of pollutants from the valley floor much sooner than anticipated.Short term changes in the weather conditions can lead to a significant variation in the level of air pollution in the Kathmandu Valley, especially during the winter season. It is interesting to note that adverse weather conditions alone can significantly enhance the pollution level in the valley even when the socio-economic activities remained subdued after the onset of Covid-19 pandemic in the last spring in Nepal as well as globally.More collaboration among the government agencies engaged in air pollution and weather monitoring and forecasting, and researchers is required. Moreover, there is a need to further strengthen the capacity of various agencies so that citizens can be informed not just about prevailing pollution levels, but forewarned a few days in advance about impending episodes of a hazardous deterioration in the AQI level.Partnering to share information about prevalent pollution levels will <a href="http://dhm.gov.np/climate/">provide valuable returns</a> on recent investments made by the government in establishing and maintaining online air quality monitoring and meteorological stations.Jagdishwor Karmacharya and Shanti Kandel are with the Department of Hydrology and Meteorology. Sunny Maharjan, Kamal Datta Acharya and Bikash Nepal helped analyse the results.

How weather elevates air pollution in Kathmandu

<img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111124/636cd1809c7e80680e08f8b9jpeg.jpg" alt="" width="880" height="864"/>That Nepal’s political leadership does not care about the health of its people is abundantly clear from its handling of the Covid-19 crisis. However, they do not seem to worry even about their own health.In the past months, they have been attending crowded indoor meetings without adequate precautions against the coronavirus. And Kathmandu’s worsening air pollution crisis, which the politicians have done nothing to address, also affects their lungs.On Wednesday morning, the Air Quality Index (AQI) was in the maroon ‘Hazardous’ range in Singha Darbar (380), Minister’s Quarters in Pulchok (380) and the official residence of the president at Shital Nibas (360).The air quality in the seats of power was in fact worse than in other parts of the capital – Kalanki intersection had an AQI of 320. Generally, the western edges of the Valley have relatively better air quality because of prevailing winds.Between 8-9AM on 6 January Nepali Times reporters fanned out across the city with ambient air quality monitoring kits to measure pollution levels. At every point, the combined US AQI readings were much above 300 -- more than 10 times higher than what the WHO regards as safe. (See map)https://www.youtube.com/watch?v=O09yyIejAlsAQI measurements:Patan Dhoka: 380Kupondole: 430Bagmati bridge: 450Tripureshwor: 450Teku: 420Kalimati: 455Balkhu: 320Kalanki: 320Swayambhu: 340Balaju: 370Maharajgunj: 360US Embassy: 360Shital Niwas: 355Japanese Embassy: 310Lazimpat: 330Thamel: 330Darbar Marg: 350Tudikhel: 370Singha Darbar: 380Maitighar: 390Naya bus park: 330This is a measurement of the concentration of tiny particles in the air, including really harmful ones less than <a href="https://www.epa.gov/pm-pollution/particulate-matter-pm-basics">2.5 microns in diameter</a>, which can lodge deep in the lungs, and are small enough to enter the bloodstream.The results show that although AQI had improved after surpassing a record 500 on 4-5 January, it was still at extremely harmful levels on Wednesday morning. In fact, in Kopundole, Tripureswor and Kalimati, AQI recorded levels above 450.By afternoon, bright sunshine and a fresh westerly breeze helped blow the smog away. Kathmandu was emitting pollution, it was just that the dirty air was being exported to districts to the east. From there, much of it was transported up the mountains for the soot to be deposited on Himalayan glaciers, making them melt even faster.Despite the majestic view of Langtang and Dorje Lakpa to the north, AQI in Patan still hovered between 200-300 on Wednesday afternoon. At one point, a neighbour set fire to refuse and the AQI spiked to 450 within minutes.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111124/636cd1829c7e80680e08f8bajpeg.jpg" alt="" width="3392" height="2316"><figcaption> </figcaption></figure>“People are blaming weather for poor air quality, but we are polluting the air throughout the year. On Monday and Tuesday, the pollutants were trapped and had nowhere to go,” says clean air activist Bhushan Tuladhar.Experts say that Monday and Tuesday’s exceptionally bad air quality in Kathmandu only stood out because it was visible. Open fires, brick kilns, vehicular emission, last week’s wildfires in the mountains, and cross-border industrial smog combined with winter inversion <a href="https://www.nepalitimes.com/latest/kathmandu-air-pollution-hits-record-high/">trapped pollutants</a> in the bowl-shaped Valley.Back in May, for the first time in many years, Mt Everest at a distance of 200km <a href="https://www.nepalitimes.com/banner/when-the-air-is-clean/">was visible from Kathmandu</a>. One factor was zero vehicular emissions and brick kilns shutting because of the lockdown.Kathmandu’s air pollution is a clear indication of governance failure. <a href="https://www.nepalitimes.com/here-now/green-sticker-green-light-to-pollute/">Corruption in emission checks</a> for green stickers, the lack of political will to <a href="https://archive.nepalitimes.com/article/nation/brick-factories-still-using-old-polluting-technology,2078">relocate brick kilns</a>, and the inability of the municipalities to control <a href="https://www.nepalitimes.com/nepali-times-search/?q=garbage+burning">garbage burning</a>.Last year, the Cabinet decided that it would declare a health emergency if AQI exceeded 300 and take measures to reduce vehicles on the roads. If it followed its own rules, the government should declare an emergency every day to protect public health.However, the ruling Nepal Communist Party has been in a crisis ever since Prime Minister K P Oli dissolved the Lower House on 20 December, and called for snap polls. The government is too preoccupied to pay attention to the double whammy of Covid-19 and air pollution.“This is a grave threat to public health, the government should have declared an emergency and taken urgent measures to curb pollution,” says Bhushan Tuladhar.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111124/636cd1859c7e80680e08f8bbjpeg.jpg" alt="" width="2000" height="3000"><figcaption> </figcaption></figure>This week, all major newspapers, radio stations and tv shows for the first time made air pollution their main news headline. But as blue skies returned, people were back on the streets oblivious to still-high pollution levels.And this was just the particles in the air, there are also poisonous invisible gases like carbon monoxide, nitrous oxides, sulphur dioxide and surface ozone. Studies have shown that most of these gases are emitted by motorcycles and scooters, of which there are 1.5 million in Kathmandu Valley alone and more are being added every day.Most Kathmandu residents are now wearing masks to protect themselves from both Covid-19 as well as particulates in the air, but masks cannot filter highly poisonous gases like carbon monoxide.<img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111124/636cd1899c7e80680e08f8bcjpeg.jpg" alt="" width="1575" height="1181">During the AQI measurement trip on Wednesday, all the sources of pollution were visible: garbage burning by the banks of the Vishnumati, cargo trucks at Kalanki spewing putrid black smoke, people warming hands by a roadside fire, dust rising from sidewalks.The problem with Kathmandu’s air quality is not so much the spike that happened on two days this week, but long-term exposure to dangerously high levels of pollution. A 2018 WHO report said such sustained exposure to dirty air could <a href="http://archive.nepalitimes.com/article/Nepali-Times-Buzz/air-pollution-decreases-life-span,3999">reduce average lifespans by nearly four years</a>. The <a href="https://www.nepalitimes.com/latest/double-whammy-air-pollution-and-covid-19/">State of Global Air</a> report said air pollution was directly responsible for 42,100 deaths in Nepal in 2019.During the lockdown, there was sharp fall in the number of people with chronic respiratory illnesses, and it looked like masks and distancing to prevent Covid-19 protected many from other infections.But Raju Pangeni, pulmonary specialist at HAMS Hospital says the numbers went up as winter set in, and vehicles returned to the streets. He says, “In the last two months we are back to nearly as many patients as we did this time of the year.”There are solutions to the Kathmandu’s worsening air quality. The municipalities have not been able to relocate <a href="https://www.google.com/url?client=internal-element-cse&amp;cx=bead8272edd0f2143&amp;q=https://archive.nepalitimes.com/article/nation/brick-factories-still-using-old-polluting-technology,2078&amp;sa=U&amp;ved=2ahUKEwjyk8-dvojuAhXNhOYKHe8CAI0QFjAAegQIAhAC&amp;usg=AOvVaw2Mh3MaSj1qbZh8PvhZrbXV">brick kilns</a>, or promote alternative building materials. <a href="https://www.nepalitimes.com/here-now/green-sticker-green-light-to-pollute/">Green stickers</a> can be ‘bought’ under the counter for Rs1,000, and there is no control of open garbage burning.Prime Minister Oli promised that foreigners would come to Nepal to “breathe clean air”. Not likely. Two years ago, he pledged to make 20% of vehicles in Nepal battery-powered by 2020, that deadline has come and gone. In fact, Oli’s favourite finance minister <a href="https://www.nepalitimes.com/here-now/an-electric-shock-to-nepals-energy-future/">hiked the tax on electric cars</a> in last year’s budget.“Air pollution is a long-term problem that needs policy level change. It should go hand in hand with education and awareness which are the precursors to clean air,” says Shisir Sharma of the group Dhristi Kathmandu that has been monitoring air quality since 2016.The good news is that this week’s pollution emergency has increased public concern about the health risks, especially <a href="https://www.nepalitimes.com/latest/covid-19-will-get-worse-before-it-gets-better/">its links with Covid-19</a>. Demand for battery-operated vehicles will rise if there is a tax rebate, and room air purifiers are flying off the shelves.Says Bhushan Tuladhar: “People have a choice to ride Safa tempo, or bicycle. Brick kilns can be cleaner. Truck emissions can be controlled.  There is a solution to pollution.”

Dirty politics = Dirty air

Nepal’s only international aviation gateway, at Kathmandu airport, will cut night-time operation hours to allow construction of taxiways, and airlines have been told to curtail flights. This is expected to lead to more than normal chaos during the height of peak autumn and spring tourist seasons at an airport that is congested even at the best of times. The airport will close from 10PM to 8AM from 8 November-31 March 2025. The taxiways will now connect to the thresholds at both ends of the runway, making the airport more efficient in handling higher frequencies of landings and takeoffs. The parallel taxiway extension will allow international flights to land every 4 minutes instead of the current every 7 minutes. At present planes have to wait to land until a plane taking off backtracks along the runway.&nbsp; Kathmandu is Nepal’s only airport with international operations, and it has only one runway that is only one way in from the south over the mountains. With the taxiway improvement, the airport will be able to handle 42 aircraft landings and takeoffs per hour — double the current capacity.&nbsp; The Civil Aviation Authority of Nepal (CAAN) has been trying to entice international airlines to also start flying to and from the other two international airports at Pokhara and Bhairawa (Lumbini) by slashing landing and handling charges. But so far only Nepal Airlines operates a weekly flight to Bhairawa from Kuala Lumpur.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241018161016_046569e53d1d66cd445cc66c697c0ef724810aec9f54bdf827481e3cd6b80c32.jpg" data-media-id="editor_0" data-image-id="20241018161016_046569e53d1d66cd445cc66c697c0ef724810aec9f54bdf827481e3cd6b80c32" data-rendition-name="original" width="2356" height="1134" loading="lazy" alt="Kathmandu airport expansion"> <figcaption>Kathmandu Airport Expansion plan with extension of taxiways to the thresholds of runways 02 and 20 that will limit airport operations from 8 November 2024 - 31 March 2025.

Many airlines currently operate regular flights to and from Kathmandu between 10PM and 8AM: Air Arabia to Sharjah, Fly Dubai to Dubai, Jazeera Airways to Kuwait, Cathay Pacific to Hong Kong, Singapore Airlines, several Nepal Airlines flights, and one of four daily flights by Qatar Airways to Doha. Jazeera Airways, FlyDubai, and Thai AirAsia have applied and got permission from CAAN to begin regular flights to Bhairawa’s Gautam Buddha International Airport. Starting 9 November, FlyDubai will start making a stopover in Bhairawa before flying on to Kathmandu. Immigration, customs and security are all fully functional in Bhairawa. In Kathmandu, the next phase of the airport upgrade includes converting the current international terminal for domestic operations, the construction of a new international terminal where the domestic departure area is now, as well as moving the hangars and the Nepal Army Air Wing to the eastern side of the runway. The apron area will also double its parking space for widebody jets. This is part of a Airport Capacity Enhancement Project that was initially funded through a $80 million loan from the Asian Development Bank (ADB), and the entire masterplan is expected to cost $800 million. This project is the latest upgrade to Nepal’s only international airport since it saw its first flight in 1949. The current international and domestic terminals are too small to handle the current annual traffic volume of 8.5 million passengers a year that is growing at 20% a year.

Kathmandu airport to cut flight hours

As Kathmandu becomes more congested and polluted, and with remote online work becoming the norm, many professional Nepalis are planning to retire in Pokhara, or move there.&nbsp; With its stunning mountain panorama, balmy winters and proximity to a profusion of wilderness areas, builders are responding to this demand with new townhouses, housing development and apartments. One such block of flats is the 10-storey <a href="https://sungavaapartment.com/">Sungava Apartment</a> located at Phulbari above the Seti River, near the point where it flows into and under Pokhara. The imposing structure near Manipal Hospital is almost complete, and on a recent visit the site was strewn with huge boulders unearthed while digging the foundation.&nbsp; The Seti brought down these boulders during a gigantic flood that geologists estimate happened 800 years ago when a chunk of Annapurna IV broke off and ploughed into the glacier below. Today, Sungava (means ‘orchid’) sits safely on a high terrace, 100m above the blue-green Seti and commands a view of Dhaulagiri, Annapurna South, Machapuchre, Annapurna III and IV.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2024102411104_5f8fc736c86ea3c08d7bef43bb727081d3cc1a2caa55ae2b441717e6044de7e9.jpg" data-media-id="editor_1" data-image-id="2024102411104_5f8fc736c86ea3c08d7bef43bb727081d3cc1a2caa55ae2b441717e6044de7e9" data-rendition-name="original" width="2016" height="1512" loading="lazy" alt="High living below the Himalaya NT"> </figure>  The soil here is conglomerate that has solidified like concrete, and the boulders were extracted by heavy earthmovers. It is intriguing to think that these metamorphic rocks as big as cars, rounded by glacial grinding, were once a part of a much higher Annapurna IV. Even for those with little interest in geology, Sungava is an ideal place to contemplate the tectonic forces that pushed these peaks into the sky to be sculpted into delicate shapes by wind, snow, earthquake and avalanche over millions of years. The view of the Himalayan panorama from Sungava’s many balconies are breathtaking when not obscured by clouds, or the haze that drifts in from across the southern border. On most days, just watching the towering pyramid of Machapuchre (Tamu name: कतासुँ क्लिको) play hide and seek with the clouds is mesmerising. There are rocks aplenty at Phulbari, and it is probably the flowers that grew along the flat terraces e that gave the place its flowery name. The boulders will hopefully be turned into a rock garden while landscaping. An nearby restaurant complex is making the best use of the stones in its design, using flat rocks as outdoor benches and tables. Sungava was designed by the husband-wife architect team of Deepak Sherchan and Jyoti Joshi of <a href="https://thedarkmermaidamarbshrestha.blogspot.com/2013/12/creative-builders-collaborative-cbc.html">Creative Builders Collaborative (CBC)</a>, which also built Heritage Plaza, Indreni Apartment and numerous other projects in Nepal. Sadbhavana retains CBC’s trademark Newari-style masonry and here it borrows from the orange brickwork of the old town of Pokhara, integrating it with modern design elements. A few of those heritage houses are still standing in Ganesh Tole and Ram Krishna Tole in Pokhara’s old quarter.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2024102411108_5eb64a4885961b6d30781cefeb1e8a313da313ac5227c7a66b60f0c7d48d6fab.jpg" data-media-id="editor_3" data-image-id="2024102411108_5eb64a4885961b6d30781cefeb1e8a313da313ac5227c7a66b60f0c7d48d6fab" data-rendition-name="original" width="1362" height="595" loading="lazy" alt="High living below the Himalaya NT"> </figure>  About 400m from the apartment past a bend on the river, and down below three tiers of terraces in the canyon is a suspension bridge. Below it, the Seti is still swollen with post-monsoon flow as it tumbles away in a hurry to head down south.&nbsp; Back at the apartment, it is quiet, far away from the hubbub of Lakeside a 15 minute drive away, and in the lap of greenery. There are 52 units at Sungava and it already has a close-knit prospective community of professionals, including doctors, publishers, engineers, and businesspeople from the renewable energy and IT sectors.&nbsp; Some residents say they opted for a second home in Pokhara to make it a ‘base camp’ to explore the Annapurnas with its many hiking trails made newly accessible with new roads. With the NRN citizenship law, overseas Nepalis can now also buy the flats. &nbsp; The floor plans include options for north and south-facing 3-bedroom apartments with verandas, and the facility has underground parking has EV charging, heated pool, sauna and gym. There are still some unsold apartments with panoramic views of the mountains and one can imagine oneself at the kitchen with its huge window, humming a ditty while preparing breakfast: “खाना पकाउँ हिमाल हेरेर...”

When the United Nations held its Summit of the Future at its headquarters in New York in September, many world leaders, including Nepal’s Prime Minister K P Oli, highlighted the effect of climate breakdown in increasing the frequency and intensity of natural disasters. What did not get as much attention was the long term impact of the climate crisis on food production. In fact, heat stress, weather extremes and the consequences on rain-fed agriculture is already being felt worldwide, undermining the chances of the <a href="https://unstats.un.org/sdgs/">UN’s Sustainable Development Goals (SDGs)</a> being met by 2030.&nbsp; The SDG’s 17 targets commit countries like Nepal to reduce poverty and inequality, end malnutrition, protect the natural environment, and ensure that citizens all enjoy health, justice and prosperity without leaving anyone behind.&nbsp; However, besides the impact of climate breakdown on agricultural production, in Nepal the area under cultivation is impacted by urban expansion, falling productivity and the need for expensive inputs like fertiliser and pesticides.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241019041052_626413c5baf4dae407ac9579231b41daeb51510aa636b75aeb7489d94cca6a62.jpg" data-media-id="editor_1" data-image-id="20241019041052_626413c5baf4dae407ac9579231b41daeb51510aa636b75aeb7489d94cca6a62" data-rendition-name="original" width="999" height="1500" loading="lazy" alt="urban agriculture in Kathmandu"> <figcaption>Kathmandu's urban sprawl is eating into its fertile cultivable lands. Photo: TAYLOR MASON</figcaption> </figure>  Now, a new study led by Nepali researcher Prajal Pradhan at the University of Groningen in The Netherlands looks at how urban agriculture may offer a solution to falling food production and meeting SDG targets. The researchers evaluated 1,450 publications exploring the contributions of urban agriculture with both positive and negative effects, and published their findings in the journal Cells Report Sustainability. Urban agriculture can help achieve 17 SDGs, positively influencing 81 targets. However, it could also undermine 51 goals.&nbsp; Read also: <a href="https://nepalitimes.com/here-now/the-vanishing-land">The vanishing land</a>, Taylor Mason “Urban agriculture offers immense potential for sustainable development, but realising this potential depends crucially on adopting practices that minimise its adverse effects while maximising its benefits,” Pradhan explains. Urban agriculture can substantially enhance urban food security, provide employment to the urban poor, serve as ground water recharge in built-up areas, and preserve open spaces that can serve as safe havens during disasters like earthquakes. However, it also presents problems like the potential health risks from contamination and the need for expensive inputs. &nbsp; “Urban agriculture plays a definitive role in advancing the SDGs, but achieving this requires tailored, context-specific solutions that address the unique challenges of different regions,” says Yuanchao Hu of Wuhan University in China and who is a researcher at the Potsdam Institute for Climate Impact Research. “But it needs equitable access and rigorous management of environmental risks.”&nbsp; Rapid urbanisation is eating into Nepal’s most fertile agricultural land, which means farming in remaining open spaces inside cities can be a viable alternative, especially as food prices rise.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241019041052_7b7c9413086226fbdc630d45acf772cfa1ced77a8970b9056ec5ec7e5226fdf8.jpg" data-media-id="editor_3" data-image-id="20241019041052_7b7c9413086226fbdc630d45acf772cfa1ced77a8970b9056ec5ec7e5226fdf8" data-rendition-name="original" width="1500" height="999" loading="lazy" alt="urban agriculture in Kathmandu"> <figcaption>A vegetable patch in between new houses in Thimi. Photo: TAYLOR MASON</figcaption> </figure>  “The conversion of Nepal’s most fertile land into cities is a severe problem,” Pradhan told Nepali Times. “Crop cultivation, horticulture, agroforestry, beekeeping, livestock rearing, or aquaculture can all be farming activities within and around cities.”&nbsp; The study makes recommendations for sustainable practices that build on the positive aspects of urban agriculture while mitigating the downsides, thereby promoting more resilient cities in future. Research shows that urban agriculture has been helping many countries attain SDG targets by enhancing food security and biodiversity while helping education and preservation of open spaces.&nbsp; Indeed, many farmers from the hinterland who have settled in Kathmandu Valley or other urban areas of the country have been practicing urban agriculture, leasing neighbourhood patches or cultivating roof gardens both out of necessity because of inflation and falling income to grow their own food, and also as a fulfilling hobby. Saurav Dhakal, a sustainability advocate with Story Cycle and now research fellow at the Asian Institute of Technology in Thailand, says there are socio-economic and environmental benefits of urban agriculture. “It provides benefits to all urban dwellers, regardless of their income status,” says Dhakal, “families get fresh food, and there are many other benefits like water retention, heat regulation and biodiversity. These are all public goods, so special government incentives may be needed.” It is not unusual to see vegetable patches and even paddy fields within inner city Kathmandu where an older generation of farmers are using available fertile land and <a href="https://archive.nepalitimes.com/article/Nepali-Times-Buzz/rooftop-gardens-kathmandu,1415">roof gardens to produce fresh, nutritious food </a>to reduce their dependence on food items that have to be bought after being trucked in from large distances.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2024101905100_1291ce98dbbb8caed8702ac4b1d469b3e13016d7ecaaf3bfd5f91c974d3c0c77.jpg" data-media-id="editor_5" data-image-id="2024101905100_1291ce98dbbb8caed8702ac4b1d469b3e13016d7ecaaf3bfd5f91c974d3c0c77" data-rendition-name="original" width="1500" height="999" loading="lazy" alt="urban agriculture in Kathmandu"> <figcaption>An older generation of farmers are using any available fertile land to continue farming but it is getting more and more difficult.

There is large outmigration from the mountains to peri-urban areas of the Tarai, to Kathmandu Valley and Pokhara, with many young men then moving abroad for work. Kathmandu Valley’s population has swelled to nearly 3 million, and is growing at 6.5% a year. Dilip Shrestha, 71, used to work for Nepal Food Corporation, so he knew firsthand about inflation, shortages and vegetables with pesticide residue. So, when he designed his new house in Kathmandu, he built a spacious roof where he grows cucumber, ginger, garlic, coriander, onions, tomatoes, chili, beans, okra, pumpkin and lettuce. His family eats healthier, and he has reduced dependence on the market.&nbsp; The co-author of the Cell Reports Sustainability journal article, Daya Raj Subedi who is a PhD candidate at Beijing Forestry University, says urban agriculture also promotes inclusion and psycho-social wellbeing.&nbsp; He says, “A crucial finding of the study is the identification of opportunities and challenges associated with urban agriculture, it can promote sustainable transformation of society.” In Banepa, 55-year-old Bijaya Manandhar in her lifetime has watched the fertile farms of her neighbourhood that used to supply vegetables to Kathmandu, now completely built up with no open space left. The pandemic lockdown prompted her to turn to the family’s <a href="https://nepalitimes.com/banner/rooftop-agriculture-on-the-roof-of-the-world">ancestral livelihood by growing food</a> not on terrace farms, but on the roof terrace.

He adds, “Crop cultivation around cities can be protected by land use plans and regulations. Promoting community-based agriculture, including rooftop gardens, requires community engagement and public-private partnerships across the food value chain.”&nbsp; Such support would accelerate the popularity of existing rooftop farming and community gardens in Kathmandu Valley, or kitchen garden initiatives in Pokhara, and building on traditional farming practices that are preserved and integrated into urban settings like in Bhaktapur and Banepa. In Lalitpur, the Women Entrepreneurship Facilitation Center promotes urban farming enhancing both sustainability and empowerment.&nbsp; Another co-author of the report, Yuanchao Hu from China says followup research of the team will aim to identify good practices in local urban agriculture practices. He adds, “There are examples of urban agriculture that optimise sustainability, ensuring that it remains a viable solution for cities globally while countries try to meet SDG targets.” Prajal Pradhan, Daya Raj Subedi, Kshitij Dahal, Yuanchao Hu, Prakriti Gurung, Sijal Pokharel, Sagar Kafle, Biplav Khatri, Sudeeksha Basyal, Monika Gurung, and Aruna Joshi.

Back to the land in the cities

The 700-year-old Lakshmi Narasingha temple in Bhaktapur houses a rare half-lion and half-human incarnation of Lord Vishnu carrying the Goddess Lakshmi. The temple was destroyed in the 1934 mega earthquake that killed 10,000 people and destroyed many monuments in Kathmandu Valley. It was rebuilt by a German project in the 1980s, but as a single-storey structure instead of its original two-tier pagoda design.&nbsp; With new findings from in-depth research, Bhaktapur municipality began re-restoring the temple in 2021, preserving its original architecture.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241017131016_2fae38cce543ad7b1f6de632feb3e212e08ed1acedd747830e949d7b8e878f18.jpg" data-media-id="editor_0" data-image-id="20241017131016_2fae38cce543ad7b1f6de632feb3e212e08ed1acedd747830e949d7b8e878f18" data-rendition-name="original" width="2048" height="1365" loading="lazy" alt="In with the old in Nepal NT"> </figure>  “Our temples and heritage sites hold deep meaning. It is disheartening to witness how often they lose their original elements, whether by design or accident,” explains Kumar Chawal of the Consumer Committee of Bhaktapur. “There is a need to preserve our architecture and protect its historical value for future generations. Otherwise, we risk losing a vital part of our identity.” The Laksmi Narsingha restoration is similar to the Bhai Dega temple in Patan Darbar Square which also collapsed in 1934, but was rebuilt with a Moghul-style dome by the Rana government at the time. Only two months before the 2015 earthquake, heritage conservationists had started to rebuild Bhai Dega as the original three-tier based on early photographs. But priorities shifted when four other temples in the square were brought down by the 7.8M earthquake on 25 April 2015.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241017131016_697ea707d9ad163be5de5f2efbf5b70d3cab771adcc22f0fae6bf937c6cb0130.jpg" data-media-id="editor_1" data-image-id="20241017131016_697ea707d9ad163be5de5f2efbf5b70d3cab771adcc22f0fae6bf937c6cb0130" data-rendition-name="original" width="2048" height="1365" loading="lazy" alt="In with the old in Nepal NT"> </figure>  This showed how damage to monuments in Kathmandu Valley spanned from one earthquake to the next. Bhai Dega restoration remains half-complete to this day because money for its restoration ran out.&nbsp; Whereas Bhai Dega restoration was done by the Kathmandu Valley Preservation Trust with grants from western embassies and international foundations, in Bhaktapur it is the municipality itself that allocated the Rs30.7 million needed to restore the Lakshmi Narasingha temple. The expected date of completion is early 2025. The municipality and local communities are focusing on two main aspects: preserving the past and promoting localisation. The restoration team has designed a blueprint for the temple by using historical photographs and insights from older generations.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241017131016_182882fdc393c99e70d1d0490319e415229563666c4934e3a582426ebf00ca30.jpg" data-media-id="editor_2" data-image-id="20241017131016_182882fdc393c99e70d1d0490319e415229563666c4934e3a582426ebf00ca30" data-rendition-name="original" width="1200" height="560" loading="lazy" alt="In with the old in Nepal NT"> </figure>  “At first, the Lakshmi Narasingha temple had only one entrance, but during the demolition process, we uncovered the foundations of four doors. Now, we are restoring all of them. This is an example of how our ancient structures have changed over time, often without our knowledge,” says Chawal. “Constructing temples is not like building houses. They carry historical and spiritual values, which is why they hold a special place in our hearts,” he adds. By replicating ancient design elements and rebuilding the temple as accurately as possible to its original form, the team has stayed true to Bhaktapur’s soul. But the restoration also revived ancient techniques that were in danger of being forgotten, generating employment for woodcarvers, masons, and contractors. The community of Bhaktapur’s Gahiti neighbourhood near the famous Nyatapola Temple has also set aside specific days for locals to volunteer in the reconstruction work. This has encouraged young people to take pride in ownership of their heritage. Families have also supported the effort by donating funds for bells, the temple pinnacle, and other structural features to the temple.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20241017131016_db850ec0c084cdbe54f65bee92dad2ad8122d20fd60ec87ec086fbb9d2f72bd6.jpg" data-media-id="editor_3" data-image-id="20241017131016_db850ec0c084cdbe54f65bee92dad2ad8122d20fd60ec87ec086fbb9d2f72bd6" data-rendition-name="original" width="2048" height="1365" loading="lazy" alt="In with the old in Nepal NT"> </figure>  “I feel at peace knowing I have contributed my sweat to restoring this temple,” said one volunteer. “It is our duty to preserve our temples and heritage. The Nyatapola area will look magical once this temple is completed.” Community mobilisation is a long-standing tradition in Bhaktapur. In the past, locals have actively participated in the restoration of other temples in the city, such as Bhairav and Nyatapola fostering a strong sense of ownership. This collective engagement has not only been crucial in preserving the city's historical monuments but also in strengthening the bond between local communities and their heritage, says officials at the municipality. While securing funding is essential, and the municipality showed it values heritage conservation, the Lakshmi Narasingha restoration is proof that active involvement and sense of responsibility of the local community is as important, if not more. Local involvement also means that the monuments will be cared for into the future, When locals take ownership of these efforts, the restored monuments are not only protected in the present but are also cared for in the future.
