Yet, nothing happens. Why?“The awareness and knowledge have not translated into corrective action,” explains environmentalist Bhushan Tuladhar. “We know about vehicle emission tests but we ignore it, open burning is bad but we don’t stop, we have the opportunity to reduce air pollution with electric mass transport but we don’t invest in it.”<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221114091156/637203009c7e80680e0b27e4jpeg.jpg" alt="" width="1500" height="1000"><figcaption> </figcaption></figure>Air pollution was directly linked to at least 42,100 deaths in Nepal in 2019. Almost half of that was due to breathing in particles smaller than 2.5 microns in diameter which can cross the air blood barrier in the lung capillaries. Most of those particles come from <a href="https://www.nepalitimes.com/here-now/green-sticker-green-light-to-pollute/" target="_blank" rel="noopener noreferrer">vehicle emission</a>.From 1990 to 2015, the number of vehicless in Nepal grew by 1,995,404 — most of them in Kathmandu Valley. In five years, that figure doubled to 3,987,267.This figure doesn’t include the exploding demand for cars and motorcycles after the end of the Covid second wave in mid-2021. Nepal spent Rs543 billion in importing vehicles, transport equipment and spare parts in four months from mid-July to mid-October, against Rs357 billion and Rs418 billion for the same periods in 2020 and 2019.“There has been an unexpectedly high demand for private vehicles in Nepal after the pandemic, especially two wheelers given the public’s hesitancy to use buses due to coronavirus fears,” says Dhruba Thapa of the National Automotive Dealers Association.<iframe style="border: none;" title="Total vehicles in Nepal" src="https://e.infogram.com/e0cdbfd0-0b3c-4f57-851e-7aced6e69116?src=embed" width="700" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe><a style="color: #989898!important; text-decoration: none!important;" href="https://infogram.com/e0cdbfd0-0b3c-4f57-851e-7aced6e69116" target="_blank" rel="noopener noreferrer">Total vehicles in Nepal</a><a style="color: #989898!important; text-decoration: none!important;" href="https://infogram.com" target="_blank" rel="nofollow noopener noreferrer">Infogram</a>Raju Chettri, CEO of the MAW Enterprises that imports Yamaha bikes in Nepal has a similar observation. He saw a decline in the annual sales of two wheelers from about 250,000 units to 190,000 right after the pandemic. But this year, the sales went up to 350,000 units.“There are two reasons behind this: pent-up demand and reduced use of public transport because of Covid fears,” Chettri says.There are <a href="https://www.nepalitimes.com/banner/poisoning-the-air-we-breathe/" target="_blank" rel="noopener noreferrer">more than 3.1 million two-wheeers in Nepal</a>, over one million of them in Kathmandu.

Motorcycle exhaust may not be as visible as diesel exhaust, but they are highly poisonous — especially when there are so many of them. Besides exacerbating respiratory diseases, the gases are carcinogenic, causing cardiovascular diseases and Alzheimer’s.The solution is to shift rapidly to <a href="https://www.nepalitimes.com/banner/nepals-electric-transport-future-is-here/" target="_blank" rel="noopener noreferrer">cleaner electric vehicles</a>, not just for healthier air but also to meet Nepal’s net-zero pledge in Glasgow and to reduce the country’s burgeoning petroleum import bill.“The priority has to be on electric public transport and supporting infrastructure,” says environmentalist Tuladhar. “Electric buses are more expensive than diesel ones, so the government has to help with capital, and better manage Kathmandu’s public transport.”<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221114091156/637203039c7e80680e0b27e5jpeg.jpg" alt="" width="720" height="480"><figcaption> </figcaption></figure>This week, Nepal opened its first electric charging station powered by solar panels for the Lumbini Development Trust. Similar charging stations can be set up for public and private vehicles in existing bus parks across Nepal and along highways.

She says, “Replacing cars with more cars even if electric only promotes consumerism. We have to give people reliable alternatives.”Kathmandu Valley Air Quality Management Action Plan held its first implementation committee meeting this week, during which it discussed lunching of a USAID-funded project for air pollution and a forecasting system with technical support from ICIMOD.“The problem of air pollution will take some time to be solved but we have started our homework,” says Indu Joshi of the Department of Environment. “At the moment, our biggest challenge is controlling open burning.”<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221114091156/637203069c7e80680e0b27e6jpeg.jpg" alt="" width="2000" height="2625"><figcaption> </figcaption></figure>Apart from transport, garbage burning and biomass fuel for household heating and cooking are also contributors to Kathmandu’s dirty air.

We must build public pressure to force the politicians into action.”A public opinion poll in this paper just before the 2017 elections showed that a majority of Nepalis were concerned about the health impact of pollution. Since 2022 will be dominated by campaigning for the next election, this could be turned into the main criteria for candidates to win votes.

Central Nepal engulfed in smoke

But Nepal’s rivers cut through the mountains, and their valleys allow smog from the plains to penetrate deep into the mountains.This haze intrusion goes up to elevations of 4,000m, and the pollution layer is more shallow and flat in winter, and inclined and parallel to the ridgeline in the pre-monsoon. The depth of this pollution layer up the valleys also decreases with elevation.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111132/636cd3969c7e80680e08f976jpeg.jpg" alt="" width="780" height="325"><figcaption> </figcaption></figure>These visible air pollution images are captured regularly by the <a href="https://modis.gsfc.nasa.gov/about/">MODIS</a> (Moderate Resolution Imaging Spectroradiometer) instrument aboard the two NASA satellites Terra and Aqua orbiting the Earth. The dull bluish haze is mostly made up of fine aerosol particles and extends right across the Indo-Gangetic plains from Pakistan to Bangladesh, as well as the Tarai in Nepal.While human-generated emissions from agricultural burning, urban, rural and industrial emissions are mainly responsible for this region-wide pollution, weather conditions and the blocking effect of the Siwalik Range also affect its spread. More interestingly, if we zoom in on the images, we can see that the haze does not just stay in the plains, but flows up into the inner Himalaya along river valleys.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111132/636cd3989c7e80680e08f977jpeg.jpg" alt="" width="780" height="381"><figcaption> </figcaption></figure>These satellite images provide valuable insight for researchers looking into the geographical spread and long-range transport of aerosol particles. Scientists at <a href="https://duke.edu/">Duke University</a> in the United States have developed a novel technique to use the high-resolution satellite images from MODIS and elevation data from <a href="https://www2.jpl.nasa.gov/srtm/mission.htm">SRTM</a> (Shuttle Radar Topography Mission) to extract the daytime haze run-up that measure intrusion length and height over the Arun Valley in eastern Nepal.The Arun River starts in Tibet, snakes around Mt Everest to find a gap between Makalu and Kangchenjunga to tumble down Himalayan gorges to meet up with the Sun Kosi and Tamor— flowing out into the Tarai at Chhatra and then through the Kosi Barrage to meet the Ganges in India. This also opens up the entry gate for haze to flow from the Indo-Gangetic Plains into the inner Himalayas.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111132/636cd39a9c7e80680e08f978jpeg.jpg" alt="" width="780" height="321"><figcaption> </figcaption></figure>In winter, the surface temperature in the plains plummets, and the air is dry. The southern edge of the Tibetan Plateau at upper levels is also battered by the sub-tropical jetstream, with weak westerly wind below it. The low surface temperature in the plains confines the pollution to a shallow <a href="https://glossary.ametsoc.org/wiki/Atmospheric_boundary_layer">boundary layer</a> that is lower than the Siwalik Range. Up-valley winds along the river valleys then transport the haze into the Inner Himalaya.The river valley-plains temperature contrast produces a pressure gradient that drives this flow up the valley during the day and down the valley during the night. Besides, the topography, vegetation cover and groundwater level in the slopes can also contribute to warming of valley air which could further amplify the up-valley wind.In addition, the daytime up-slope and night-time down-slope winds developing in the river valleys also play and important role in ventilating the air pollution from the valley surface.Measurements of the nature and size of fine aerosols were conducted for the first time in the middle Himalayan region in the pre-monsoon. In general, the aerosol size distribution peaks around 100nm, which is usually the oldest, most processed background aerosol and about the size of the Covid-19 virus.Another smaller peak around 20 nm, is indicative of fresh but not necessarily local aerosols. The chemical composition of PM2.5 (particulate matter below 2.5 microns) is dominated by organic matter. Organic carbon (OC) comprises the major fraction (64–68%) of the aerosol concentration followed by ionic species (24–26%), Elemental Carbon (EC) compromises 7–10% of the total composition and 27% of OC is water soluble.Elemental Carbon and Organic Carbon together are aerosols contributed by burning of wood fuels, crop-residue, coal including vehicular emission and others. The light absorbing properties of elemental carbon play a crucial role in atmospheric warming and surface cooling due to their interaction with the daytime solar heating.Industrial and vehicular emissions, biomass burning, soil dust and others including chemical transformations in the atmosphere contribute to the ionic species in aerosols. These are readily water-soluble parts of the aerosol which along with organic particles aid in their growth in presence of moisture, contributing to increase in optical thickness of haze.The aerosol concentration also changes over the day. It increases in the morning (05:00-10:00) and in the evening (17:00-22:00). The lower values in the afternoon could be attributed partly to more mixing, and increase in the boundary layer height.During the night, the downslope winds lift the warm air mass in the valley, resulting in the decrease of the aerosol concentration near the surface. On the other hand, aerosol loading can also be eventually washed away by local rainfall during the pre-monsoon and winter.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111132/636cd39c9c7e80680e08f979jpeg.jpg" alt="" width="780" height="300"><figcaption> </figcaption></figure>While pollution haze is visible even in satellite images, its quantitative measurements can also be made by remote sensing. Haze and dust particles in the air block sunlight reaching the ground by absorbing and scattering it. This property of aerosols is used to estimate the Aerosol Optical Depth (AOD).A long-term average of winter AOD from December-February over the last 20 years in the region shows that winter haze extends throughout the Indo-Gangetic plains, with relatively higher readings for the eastern regions of Bihar, West Bengal and Bangladesh, across Nepal’s southeastern border. The regional average winter AOD also shows an alarming increase in the past two decades due to increase in emissions from increased crop-residue burning, rapid urbanisation, industrialisation, etc.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111132/636cd39e9c7e80680e08f97ajpeg.jpg" alt="" width="780" height="481"><figcaption> </figcaption></figure>Aside from transboundary haze, this winter has also seen an increase in wildfires that have exacerbated the pollution in Nepal’s Inner Himalayan valleys. The Pathivara and Annapurna Conservation Area fires in December, followed by uncontrolled wildfires in Manang, Lamjung and Rasuwa in January were clearly visible in NASA satellite images.The very high pollution levels in Kathmandu Valley on 6-7 January was also aggravated by overcast skies which subdued the ventilation mechanism of the valley, but smoke from these wildfires also acted as contributors. Since the daily satellite data is in the public domain, they could be used along with global models by Nepal’s met office to nowcast air pollution episodes over the Himalaya.While local air pollution can be brought under control in the interest of protecting public health by the local governments with appropriate policy and regulation, it is trans-boundary pollution that cannot be easily addressed. It requires regional collaboration to adopt and implement policies to reduce sources of pollution like crop residue burning, vehicular and industrial emissions. The atmospheric initiative at the Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD) could be one such mechanism.More immediately, there is an urgent need to set up permanent air quality monitoring stations along Nepal’s major river valley outlets to monitor trans-boundary air pollution and more research by universities in Nepal to improve our knowledge of local and regional pollution so that policy makers can make better decisions.Prabhakar Shrestha is a research scientist working at Bonn University, Germany.<img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111132/636cd3a19c7e80680e08f97bjpeg.jpg" alt="" width="89" height="103">

There were similar fires this spring. Photo: NASA</figcaption></figure>The global media, world leaders, celebrities and environmental activists have expressed alarm at the mass arson in the Amazon rainforest, even as Hurricane Dorian and the heatwaves of this northern hemisphere summer underline the seriousness of the climate emergency.The Amazon spans nine South American countries, and the vast continental forest was a biodiversity hotspot even before the fires were started by farmers emboldened by Brazil’s President Jair Bolsanaro’s encouragement to clear trees to make way for farms.The Amazon acts as a vast sink for atmospheric carbon. Scientists have said that preserving forests and re-greening degraded land is the single most effective way to reduce carbon dioxide in the atmosphere, even as countries globally work on slashing emissions.Mass burning of forests not only releases more carbon into the atmosphere, but also decreases the capacity of the planet to absorb carbon dioxide. Besides this, forests also fulfil critical life-affirming functions, such as maintaining water quality, sustaining bio-diversity and regulating micro-climates and weather processes.Read also: <a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/?p=32836&amp;preview=true" target="_blank" rel="noopener noreferrer">Mustn't blame everything on Climate Change,</a> Editorial<a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/?p=32864&amp;preview=true" target="_blank" rel="noopener noreferrer">The Third Pole is warming faster than expected,</a> Kunda DixitHowever, Brazil does not have a monopoly on forest destruction. In 2017 and 2018, massive forest fires in California raged for weeks, killing 100 people. Fires started by farmers clearing forests for agriculture and palm oil plantations in Kalimantan and Sumatra blanket Southeast Asia in smoke every year.Forest fires have also become more common in Nepal and across the Himalaya. In March 2009, following the failure of winter rains, enormous fires raged across the country destroying more than 105,000ha of forest land, and killing 43. (See NASA satellite image below.) In the past year there have been 2,771 fires in which 89 people have been killed, according to the National Emergency Operation Centre. Damage to property and livestock totalled Rs4 billion.Big multiple fires, like these during spring, lead to black carbon or soot being transported by prevailing up-valley winds to be deposited on the snow, reducing its ability to reflect sunlight, and increasing ice melt during the spring thaw. Measurements on the Yala Glacier in Langtang have shown that up to a quarter of the ice melt is now due to dirty snow — the rest is caused by rising global average temperatures.Increasingly rapid warming of the earth’s surface, erratic rain and droughts make forests more vulnerable to fires — even in Nepal’s successful community forests, which have helped increase the country’s total canopy cover.Read also:<a href="https://www.nepalitimes.com/?p=32892&amp;preview=true" target="_blank" rel="noopener noreferrer">Tree-mendous,</a> Peter Gil<a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/here-now/trees-politics-and-greed/" target="_blank" rel="noopener noreferrer">Trees, politics and greed</a>, Mukesh PokharelThere has been a global effort to compensate countries, forest dependent people and local custodians for protecting forests instead of cutting them down. After a conference in Bali in 2007, Nepal got involved in the program Reducing Emissions from Deforestation and forest Degradation (REDD+). But despite the transfer of some global funds to forest groups, uncertainty about the mechanism, technical considerations around measurement, and avoiding loss of the carbon stock have prevented REDD+ from being more effective, efficient and equitable. Moreover, in countries like Nepal with leaky bureaucracies, the benefits rarely reach local communities and the real managers of forests.Other issues, such as unclear tenure rights, limited access to resources for forest dependent people, lack of governance reforms, centralising tendencies of forest departments, inequitable benefit sharing and the poor implementation of social and environmental safeguards, continue to plague programs like REDD+. Overharvesting, illegal logging, infrastructure and conversion to plantations make conservation more difficult when we need forests more than ever before.Read also: <a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/here-now/mosquitoes-move-up-mountains-as-the-earth-warms/" target="_blank" rel="noopener noreferrer">Mosquitoes move up mountains as the earth warms</a>, Sonia Awale<a href="https://www.nepalitimes.com/here-now/climate-health-emergency/">Climate-health emergency</a>, Sonia AwaleForests have inherent intrinsic value: they cool the air, sustain biodiversity, provide food, absorb carbon and produce a range of other ecosystem services. Yet, rising temperatures will introduce new risks, making forest areas more susceptible to fires, including in Nepal. The land turns dry during non-monsoon months, fanning fires that in turn destroy vegetation and undergrowth, exposing more land surface to erosion during rains and increasing the sediment loads on rivers, leading to more flash floods.Already burdened with growing enough to feed their families, small-scale farmers across Nepal will find it increasingly harder to adapt to this changing reality. Without pragmatic measures involving communities and buttressing local capacity to address fires, the climate crisis will bring risks to the very idea of banking carbon in forests across the mountains, hills and plains.The Amazon fires should remind us of the urgency of formulating policies for least developed countries like Nepal, policies that emphasise building institutional capacity backed by resources to deal with potential large-scale forest fires. Without this effort, the past success of Nepal’s community forestry programs could be in serious peril.Read also: <a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/here-now/protecting-kathmandus-historic-roofscape/" target="_blank" rel="noopener noreferrer">Protecting Kathmandu’s historic roofscape</a>, Anne Feenstra<a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/here-now/tourism-aviation-and-carbon/" target="_blank" rel="noopener noreferrer">Tourism, aviation, and carbon</a>, Sanghamitra Subba<a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/here-now/climate-summit-leads-packed-un-agenda/" target="_blank" rel="noopener noreferrer">Climate Summit leads packed UN agenda</a>, Thalif DeenAjaya Dixit is research adviser at the Institute for Social and Environmental Transition (ISET-Nepal) and contributes this column Climate for Change monthly.  This story is part of <a style="background-color: #ffffff; letter-spacing: 0.15px;" href="https://www.nepalitimes.com/latest/world-joins-to-cover-climate/" target="_blank" rel="noopener noreferrer">Covering Climate Now</a>, a global collaboration of more than 250 news outlets to strengthen coverage of the climate story.

Average life expectancy is reduced by at least four years in the worst-affected areas like Kathmandu Valley, Chitwan and other parts of the Tarai. “Air pollution is a silent killer and while it is difficult to quantify its heath impact, hospitalisation due to serious respiratory diseases has increased sharply in recent years,” says chest specialist Raju Pangeni at HAMS Hospital in Kathmandu. “It is now causing heart attacks, kidney diseases, osteoporosis and dementia. Air pollution is more dangerous than smoking cigarettes.”Read also:<a style="background-color: #ffffff; outline: 0px; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/?p=27454&amp;preview=true" target="_blank" rel="noopener">#Beat Air Pollution</a>, Editorial<a style="background-color: #ffffff; font-weight: bold; letter-spacing: 0.01em; font-size: 15px;" href="https://www.nepalitimes.com/?p=27475&amp;preview=true" target="_blank" rel="noopener">Solution to pollution</a>, Pallavi Pant and Anobha GurungNon-smokers in Kathmandu are now suffering from diseases that you would expect to see afflicting chain smokers. And residents of the capital who smoke get a double whammy.“Controlling tobacco in Nepal is already such a big challenge, but  Kathmandu’s degrading air quality has doubled the disease burden,” says health activist Shanta Lall Mulmi. Ironically, World No Tobacco Day falls on 31 May, just four days ahead of Environment Day. Because Nepal’s national government and municipalities have done little to reduce risk, citizens have adopted their own methods of personal protection: wearing masks, installing air purifiers at home and office, cancelling morning walks, and monitoring air pollution levels on apps before allowing children to play outside.There are dozens of varieties of masks available in the market, along with air purifiers that cost more than Rs130,000. But public health specialists discount their efficacy and stress that the best solution is to reduce air pollution at sources.  Read also:<a style="background-color: #ffffff; font-weight: bold; letter-spacing: 0.01em; outline: 0px; font-size: 15px;" href="https://www.nepalitimes.com/?p=27476&amp;preview=true" target="_blank" rel="noopener">Toxic bubble</a>, Ajaya Dixit<a style="background-color: #ffffff; font-weight: bold; letter-spacing: 0.15px; outline: 0px;" href="https://www.nepalitimes.com/?p=27467&amp;preview=true" target="_blank" rel="noopener">Bad Air</a>“A mask at best is a temporary solution and does not block harmful gases. Their effectiveness also varies depending on the work place, environment and fitting. Because indoor air pollution levels are also high, ideally you would have to wear a mask 24 hours a day,” says Pangeni. Air pollution is also the main environmental risk factor for non-communicable diseases like cancers and lung diseases, concludes a recent report by the NCD Alliance and the Forum of International Respiratory Scientists: ‘The challenge is great, but the cure is straight-forward... it must be met by national, regional, local and personal responses. Collective action from many sectors is needed to assure that everyone can breathe clean air.’Indeed, a long-term solution requires policy level intervention and coordination between all branches of government. Electrified public transport would have been a good place to start, but 6 months after Prime Minister KP Oli launched an electric mobility action plan to turn at least 20% of public vehicles into battery-operated ones by 2020, progress has been slow. Read also:<a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/?p=27455&amp;preview=true" target="_blank" rel="noopener">How to clean up Kathmandu’s air</a>, Anil Chitrakar<a href="https://www.nepalitimes.com/banner/poisoning-the-air-we-breathe/" target="_blank" rel="noopener">Poisoning the air we breathe,</a> Sonia AwaleThe government slashed taxes on electric vehicles, but much of the supporting infrastructure required, like charging facilities, uninterrupted electric supply and adequate parking lots, has not even been planned.“The first step in controlling air pollution is with electric public transport because vehicular emissions make up the majority of pollutants in Kathmandu’s air,” says environmentalist Bhushan Tuladhar.With neighbouring India and China committed to manufacturing only electric automobiles by 2030, Nepal will be forced to go electric. Getting prepared now will make that transition smoother.The US government held a meeting in Kathmandu this month of its embassy staff specialising in air pollution based in 30 Asian countries. On hand was Marcia Bernicat of the US Bureau of Oceans and International Environment and Scientific Affairs. “Dealing with a problem that is transboundary in nature requires strong regional cooperation,” she said. “When you can frame the problem in terms of how many people are dying and how much productivity is lost, then it becomes much more urgent.”Quantifying the socio-economic impact of air pollution on a country will be vital in raising awareness among the public as well as policy makers and leaders, but as we have seen in Nepal it does not immediately lead to policy change.   Read also:<a style="background-color: #ffffff; font-weight: bold; letter-spacing: 0.01em; outline: 0px; font-size: 15px;" href="https://www.nepalitimes.com/?p=27487&amp;preview=true" target="_blank" rel="noopener">One Atmosphere</a>, Arnico Pandey<a style="background-color: #ffffff; font-weight: bold; letter-spacing: 0.01em; outline: 0px; font-size: 15px;" href="https://www.nepalitimes.com/?p=27462&amp;preview=true" target="_blank" rel="noopener">Green sticker = green light to pollute</a>, Sonam Choekyi Lama <h2>Maskmandu</h2> There are dozens of types of masks available in Kathmandu. There are cloth masks and surgical ones, some are disposable but many use replaceable filters. Prices range from Rs10 to Rs10,500. Most make various performance claims based on lab tests but factors like the mask’s fit play important roles. Take your pick, but remember the best thing is to reduce the source of pollution.  <img width="2228" height="1200" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221108121148/636a42689c7e80680e04a6d1jpeg.jpg" alt=""><img width="2724" height="1800" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221108121148/636a426b9c7e80680e04a6d2jpeg.jpg" alt=""><h2>Costly is not better</h2> Researchers at the University of Edinburgh recently concluded that surgical masks blocked 80% of particles sized 0.007 microns. Similarly, a University of Massachusetts study found that the good old surgical mask blocked 60% of 0.03 micron particles, and over 90% of 1 micron and 2.5 micron particles. Of course, a mask’s effectiveness depends on how well it fits on the face, but a simple, disposable surgical mask can be more cost-effective than those fancy looking expensive ones.

The survey was conducted via social media and asked residents of Kathmandu Valley about the pollution level in their neighbourhood, their commuting habits and their perspective on actions needed to improve air quality.Carried out by Air South Asia and Clean Up Nepal, the survey results understandably show that with a few outliers, most people living inside the Ring Road found the air they breathe Bad or Very Bad. Generally, the air was considered to be cleaner the further the respondents lived from the city core. However, the perception of air pollution was worse along busy intersections outside the centre, like Chabahil, Kalanki or Koteswor.Only along the foothills, in Mata Tirtha, Budanilkantha or Changu Narayan, did people feel the air quality was better.

Asked how, most noted respiratory problems, chronic cough, sore throat, asthma attacks, lack of concentration and skin rashes, while other complained of clothes getting dirty. Interestingly, some included foul smell from nearby streams as ‘air pollution’, and said the stench was ‘unbearable’. Some said they did not take morning walks anymore, or venture into the streets during rush hour, and if they did, always wore masks.“Having fresh air to breathe is a human being’s most basic right and that right has been violated to an unimaginable extent in Kathmandu,” said one Naya Bazar respondent.Asked what they think are the main sources of air pollution in their area, more than 90% cited road-side dust caused by widening and delayed construction, vehicle pollution and open garbage burning. (see graph) Many noted that open spaces were shrinking, trees were being cut and plastic waste was burnt openly on streets.

They should get real experts to work on this problem.”Air pollution in Kathmandu appears to have got so bad that it is affecting people’s choice of where to live. This could ultimately reduce land prices along areas considered heavily polluted. Kathmandu residents who can afford it have already bought farms in surrounding districts, which have been sold by villagers moving in the opposite direction to Kathmandu, or abroad. Many say they are fleeing air pollution in the Valley. Indeed, some respondents even said they are thinking of relocating outside the capital, or even emigrating because of the bad air.Some, like this respondent in Thapathali, even noted that the family’s medical expenses had shot up because of medical treatment for respiratory ailments: “The air quality is getting worse compared to previous years. The air we breathe mainly contains particulates that are inhaled and affect our respiratory system. We are suffering from frequent headaches and eye irritation. We have to spend a lot of money on expensive medicines. If the air quality improved, we could use the money for recreational activities to improve our physical fitness and mental health.”Read also:<a href="https://www.nepalitimes.com/?p=27462&amp;preview=true" target="_blank" rel="noopener">Green sticker = green light to pollute</a>, Sonam Choekyi Lama<a href="https://www.nepalitimes.com/banner/poisoning-the-air-we-breathe/" target="_blank" rel="noopener">Poisoning the air we breathe,</a> Sonia Awale

Bad Air

https://www.youtube.com/watch?v=c0Sv3a2LjxoVehicle owners in Kathmandu need to pass an annual emission test, but many just buy Green Stickers over the counter while some even have them home delivered.Given the number of diesel buses and trucks spewing toxic black smoke in Kathmandu, it is no surprise that most drivers cheat. Lackadaisical and time-consuming inspection, corruption and the lack of political will have made a mockery of Nepal’s strict emission standards.The 2003 standards require four-wheelers registered in 1980 or before to emit carbon monoxide (CO) less than 4.5% of total gases, or not more than 1,000 parts-per-million of hydrocarbons. Vehicles registered after 1980 cannot exceed 3% of CO. If they do, they do not get a Green Sticker. It seems straightforward, but the route to getting dirty vehicles off the road is full of twists and turns.“There is no political will,” sums up the executive director of Sajha Yatayat, Bhusan Tuladhar. “If there was, this system would work perfectly.”Read also:<a style="background-color: #ffffff; font-weight: bold; letter-spacing: 0.01em; outline: 0px; font-size: 15px;" href="https://www.nepalitimes.com/?p=27476&amp;preview=true" target="_blank" rel="noopener">Toxic bubble</a>, Ajaya Dixit<a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/?p=27563&amp;preview=true" target="_blank" rel="noopener">Air pollution is more dangerous than smoking</a>, Sonia AwaleBypassing the system by bribing inspectors is the most common method of getting a Green Sticker. A test costs Rs50, but for Rs500 middlemen will get you a sticker without a test. It is Rs1,000 to have the sticker delivered at home.There are artificial delays and queues at the Department of Transportation Management at (DoTM) Ekanta Kuna to tempt time-pressed vehicle owners to fork out Rs500 for the Green Sticker.“I don’t think keeping the vehicle in line for a week is cost-effective; why wait in a queue? It is much easier to just pay under the table,” admitted Suraj Tamang, a driver at Ekanta Kuna earlier this month.There are just two emission monitoring centres in Kathmandu Valley for more than 400,000 four-wheelers. Up to 200 vehicles visit the DoTM every day, and some eight diesel and four petrol cars fail the test daily on average, said Yam Bahadur Chhetri at the DoTM.If they cannot get the sticker under the table, drivers go to elaborate lengths to pass the test, adjusting the carburettor and then getting a garage to make it a smoke belcher again after they get the sticker. Traffic police rarely check if a car with a Green Sticker still has a smoky tailpipe.Read also:<a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/?p=27454&amp;preview=true" target="_blank" rel="noopener">#Beat Air Pollution</a>, Editorial<a style="background-color: #ffffff; outline: 0px; font-weight: bold; letter-spacing: 0.01em; font-size: 15px;" href="https://www.nepalitimes.com/?p=27475&amp;preview=true" target="_blank" rel="noopener">Solution to pollution</a>, Pallavi Pant and Anobha Gurung<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221108121148/636a42469c7e80680e04a6c4jpeg.jpg" alt="" width="1400" height="786"/><figcaption>Pic: SONAM CHOEKYI LAMA</figcaption></figure>But with rising awareness about air pollution in Kathmandu and the contribution of vehicular emission, many are asking why if driving under the influence (known by its Nepali acronym MaPaSe) was so easy to control, the same cannot be done for car exhausts.“It can be like MaPaSe — some people sometimes may evade checking, but overall the system will work,” says Tuladhar, who suggests deploying police with emission testers at busy bus terminals like Ratna Park.Tuladhar says 20% of vehicles cause more than 50% of the pollution, so getting rid of half the pollution should be as simple as cleaning up 20% of the cars.But the best solution would be a strategy to switch to electric public and private transport, he adds.

The average PM2.5 (concentration of particles smaller than 2.5 microns) in Kathmandu has increased from 88 to 100 µg/m3 between 1990 and 2017. The country needs a sustained and holistic long-term approach, not stop-gap measures, to control the main pollutants from <a href="http://archive.nepalitimes.com/page/every-breath-you-take-air-pollution" target="_blank" rel="noopener">vehicular emissions</a>, waste burning, <a href="https://www.nepalitimes.com/banner/poisoning-the-air-we-breathe/" target="_blank" rel="noopener">dust from roads</a> and construction sites, <a href="http://archive.nepalitimes.com/article/nation/earth-bricks-for-cleaner-and-healthier-kathmandu,4161" target="_blank" rel="noopener">brick kilns</a> and <a href="https://www.nepalitimes.com/opinion/no-smoke-without-fire/" target="_blank" rel="noopener">cooking with biomass</a>, not stop-gap measures.The national government has taken some action for air pollution mitigation, but most sources are linked to civic and governance issues. For example, open garbage burning as a source of air pollution can only be solved through systematic changes in waste management.Action on air pollution hinges on the availability of reliable information on trends, sources and impacts of pollution. Nepal’s national government has invested in air quality monitoring and currently there are more than 15 monitors across the country, including five real-time monitors in Kathmandu Valley.Read also:<a style="background-color: #ffffff; font-weight: bold; letter-spacing: 0.15px; outline: 0px;" href="https://www.nepalitimes.com/?p=27467&amp;preview=true" target="_blank" rel="noopener">Bad Air</a><a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/?p=27563&amp;preview=true" target="_blank" rel="noopener">Air pollution is more dangerous than smoking</a>, Sonia AwaleReal-time air quality data from these stations is available <a href="http://www.pollution.gov.np/" target="_blank" rel="noopener">online</a> but the website does not support access to historical data.

Till the late 1970s, the Valley’s built-up areas coalesced around historical settlements. After the 1990, the cities saw exponential growth, a process accelerated by war and declining agriculture in the countryside. Lack of jobs drove Nepalis first to Kathmandu and then overseas. The remittances that workers abroad sent back in turn fuelled the Valley’s real estate boom.Urbanisation, unplanned growth, lack of public transport and endemic corruption have enveloped Kathmandu Valley in a smog blanket most days. Nearly 38% of this air pollution is from vehicle emissions; other sources include dust from roads, excavations, debris of demolished buildings, construction sites, brick kilns, open burning of plastic and solid wastes, inefficient hospital incinerators, rice husk/coal/wood-burning industries, crushers and mixers, asphalt plants and metal and automobile repair units.Read also:<a style="background-color: #ffffff; outline: 0px; font-weight: bold; letter-spacing: 0.01em; font-size: 15px;" href="https://www.nepalitimes.com/?p=27462&amp;preview=true" target="_blank" rel="noopener">Green sticker = green light to pollute</a>, Sonam Choekyi Lama<a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/?p=27455&amp;preview=true" target="_blank" rel="noopener">How to clean up Kathmandu’s air</a>, Anil ChitrakarThe World Health Organization says the mean annual and 24-hour concentration of PM2.5 (particles smaller than 2.5 microns in diameter) in the air should be less than 10µg/m3 and 25µg/m3 respectively. In Kathmandu Valley, both parameters are much higher year-long, and the capital is among the top 10 most polluted cities in the world.Air pollutants also blow in from north India, making the problem a transboundary one. Exhaust from commercial jets and short-haul aircraft contribute too, but is overlooked. Once inhaled, the fine particulates are carried via the bloodstream to our cells, where they can cause strokes, dementia, mental retardation, pulmonary disease and cancer.The pollution is directly related to poor governance — procedural lapses, almost non-existent regulation and enforcement, and a system of national, provincial and municipal governments either incapable or too steeped in greed to deal with it.Read also:<a style="background-color: #ffffff; font-weight: bold; letter-spacing: 0.01em; outline: 0px; font-size: 15px;" href="https://www.nepalitimes.com/?p=27487&amp;preview=true" target="_blank" rel="noopener">One Atmosphere</a>, Arnico Pandey<a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/?p=27454&amp;preview=true" target="_blank" rel="noopener">#Beat Air Pollution</a>, EditorialThe overall outcome has been the growth of a concrete jungle without any form, aesthetics or character, with polluted water, land and air as by-products. Not only does Kathmandu have a serious air pollution problem, but its summer days are now urban heat islands because open spaces have been built over.Residents of the capital know they have a problem: they breathe it every day. Politicians and bureaucrats are also aware. Yet public outrage is not translating into action. The best way to end air pollution is to begin with its source. This year, Nepal’s petroleum import bill is likely to exceed Rs220 billion, double the amount three years ago.A year ago, the government gave a positive signal by reducing customs on the import of electric cars and buses to 10% and 1% respectively. All electric vehicles are now also exempt from annual road tax. This is not enough. Despite the tax rebate, Kathmandu has no operating electric buses because of the high upfront cost, although they bring multiple, long-term benefits: zero emissions, improved health, use of indigenous hydro energy and lower fuel import bills.Read also:<a style="background-color: #ffffff; font-size: 15px; letter-spacing: 0.01em;" href="https://www.nepalitimes.com/?p=27563&amp;preview=true" target="_blank" rel="noopener">Air pollution is more dangerous than smoking</a>, Sonia Awale<a style="background-color: #ffffff; outline: 0px; font-weight: bold; letter-spacing: 0.01em; font-size: 15px;" href="https://www.nepalitimes.com/?p=27475&amp;preview=true" target="_blank" rel="noopener">Solution to pollution</a>, Pallavi Pant and Anobha GurungMore than 500 electric cars and 1,500 electric scooters now use the Valley’s roads.

Other immediate actions should include rigorous pollution test of vehicles and fuel quality, improving the condition of roadside workshops and making brick kilns and incinerators more efficient.These pursuits would require mapping of pollution sources, monitoring, data analysis, adaptive policies and demonstrable actions. Understanding the policies that neighbouring countries are implementing to phase out fossil-fuel vehicles is needed to avoid the risks of Nepal becoming their dumping ground.As we take these measures, let us place images of our children in front of us, as a reminder that actions taken today will save their health and that of their children.Read also:<a style="background-color: #ffffff; outline: 0px; font-weight: bold; letter-spacing: 0.15px;" href="https://www.nepalitimes.com/?p=27467&amp;preview=true" target="_blank" rel="noopener">Bad Air</a><a style="background-color: #ffffff; font-weight: bold; letter-spacing: 0.01em; outline: 0px; font-size: 15px;" href="https://www.nepalitimes.com/?p=27476&amp;preview=true" target="_blank" rel="noopener">Toxic bubble</a>, Ajaya DixitAjaya Dixit is Executive Director of Kathmandu based ISET-Nepal.

Toxic bubble

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. Photo: TAYLOR MASON </figcaption> </figure>  Nepal’s urban population grew rapidly from only 3.6% in 1991 to 25% today. 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.

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.

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.
