For a year or two after the 25 April 2015 earthquake, the residents of Kathmandu were too terrified to return to their high-rise apartments. None of them collapsed in the 7.8 disaster, but many sustained serious structural damage. &nbsp;
Fast forward nine years, and they have all but forgotten that frightful day. Kathmandu is back to building substandard structures, even as land prices drive developers to build taller.&nbsp;
With no more space to spread horizontally, Kathmandu is going vertical. But structural engineers say most of the high rises do not take into account seismicity, soil condition, construction methods, quality of raw materials, fire hazard, and search and rescue in collapsed concrete structures.
“Much of our focus since the 2015 earthquake has been on building and construction, but not as much on where we are building,” warns Sangeeta Singh, Professor of Urban Planning and Deputy Director of Centre for Disaster Studies at the Institute of Engineering.

She adds: “Kathmandu is not really suited for high-rises. We have to first test the condition of the soil, but building permits are being issued without this fundamental step.”
Kathmandu Valley is a former lakebed with soft topsoil prone to liquefaction and excessive shaking, as seen during the 1934 megaquake. Many ruptures tore up the surface in 2015. &nbsp;
During an earthquake, the rock layers below Kathmandu ring like a bell and the vibrations on the surface take between 0.5 to 2 seconds for one oscillation. Buildings also vibrate, but at different frequencies depending on their height, construction material, and arrangement of their structural components.
At five floors, the vibration period of a building is 0.5 seconds, which is the same as that for Kathmandu Valley, and this could cause more damage, says structural engineer Surya Narayan Shrestha at the National Society for Earthquake Technology - Nepal (NSET).
“Building anything that is five storeys or higher in Kathmandu needs special design and structural considerations,” says Shrestha.

Technologies exist to reduce seismic risk in high-rises, and these are used in earthquake-prone cities like Tokyo, Los Angeles, Jakarta or Mexico City.&nbsp;
Base isolation, for example, separates the vibration of the land and the building, reducing damage from soil-building resonance. Base isolators move and stretch under pressure, absorbing much of an earthquake's impact by reducing swaying and shaking. &nbsp;
Seismic dampers change the pattern of vibration altogether, dissipating energy as vibrations move across a structure. But these are all expensive technologies, and none of the high-rises in Kathmandu use them.
However, Nepali engineers who can help with technology transfer are working in the field in Nepal and overseas. Kathmandu’s high-rises are already very expensive, and making them seismic-resistant would be an incremental cost.

The shape of high-rises also matters. Reinforced concrete buildings with asymmetric designs of the kind that are seen in newer structures in Kathmandu experience more torsion and shear during quakes. High-rises with regular geometry are stronger. &nbsp;&nbsp;
An even bigger concern is that of emergency evacuation and rescue in case of fire or earthquake. Kathmandu fire services do not have ladders that reach the higher floors of most new structures.
“High-rises mean more people and potentially higher casualties,” explains Shrestha. “We need immediate evacuation routes, fire escapes, emergency ladders, and fire trucks that can reach higher. Right now, safety features are voluntary and not mandatory.”
The street access, shelters, open spaces, and evacuation routes are integral to disaster preparedness and the safety of neighbourhoods and not just buildings. Most new high-rises in Kathmandu have narrow access roads.

Since most of the buildings that survived the 2015 disaster were reinforced concrete structures, it fed the misconception that they are safer. But Himalayan seismologists say that if the intensity and duration of the shaking had been just a little higher, many substandard concrete structures would have collapsed.&nbsp;
And that is the final gap: Nepal’s limited expertise and equipment for search and rescue inside collapsed concrete structures. Kathmandu’s high-rises need to be better prepared for the next Big One.
“Structural safety and design were at the front and the centre after the 2015 earthquake, we also revised some building codes but we are back to square one with contractor-driven construction, especially in peri-urban areas,” says Sangeeta Singh, who is also with the National Planning Commission. “We need to monitor construction as much as design.”&nbsp;
Shrestha at NSET agrees there have been improvements in building practices in the past nine years, but adds, “We have both learnt and unlearnt lessons from 2015. The awareness hasn’t yet translated into action on safety.”

So the 52-year-old just went back to her ancestral livelihood — not on terrace farms, but on her rooftop terrace.“The food on my plate now comes from my roof,” says Manandhar proudly. “We had to regain our food self-sufficiency during the pandemic so we had no other option but to grow vegetables in our roof garden.” <figure><img width="1600" height="1145" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20230112100128/63bfd2b39c7e80680e0d3032jpeg.jpg" alt=""><figcaption>Bijaya Manandhar tending her rooftop garden.

In future, the socio-economic and environmental sustainability of food systems will largely be determined by the diet of urban and peri-urban inhabitants. In Nepal, the urban population has spiked dramatically from 3.6% in 1991 to 6.5% in 2001, and is now 21%. Most of the migration took place during the conflict, and later families moved to urban areas for jobs. Kathmandu Valley, with an estimated population of 2.54 million, is growing at 6.5% per year, as one of the fastest-growing metropolitan areas in South Asia. <figure><img width="720" height="540" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20230112100128/63bfd2b79c7e80680e0d3033jpeg.jpg" alt=""><figcaption>Women gardeners participating in Kausi Queen Competition 2078 organized in coordination of Banepa Municipality.

But there are now tall houses where her family farm once was. “The land is no longer for planting crops now, they now plant buildings there,” she says, gesturing at the houses from her rooftop. <figure><img width="1398" height="930" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20230112100128/63bfd2ba9c7e80680e0d3034jpeg.jpg" alt=""><figcaption>Aerial images of house roofs with urban farming in Kanthu Tole, Banepa. Photo: GEOMATICS ENGINEERING SOCIETY, KATHMANDU UNIVERSITY.</figcaption></figure>Once known for its succulent vegetables that supplied the market in Kathmandu, Banepa is now the site for a research project by the Geomatics Engineering Society of the nearby Kathmandu University to study the scope for rooftop farming in the municipality. The study mapped roof spaces suitable for farming using OpenStreetMap to create geospatial data. This was a pioneering study, and could be upscaled nationwide if successful.“Our research not only tries to shed light on the trends and benefits of rooftop farming, but creates a baseline survey, database and information to be used in the future,” explains Rehana Shrestha, Doctoral Researcher at Universität Bremen and adviser to the urban rooftop farming project in Banepa.While the idea of rooftop farming is quite common and widely practised, the data regarding buildings, houses, and people practicing it in any peri-urban areas were thus far unavailable. That is why the open source OpenStreetMap (OSM) came in handy, as a platform to identify buildings with suitable roofs. The researchers still needed high-resolution imagery to map out Banepa’s buildings and roofs in detail.  <figure><img width="1397" height="933" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20230112100128/63bfd2c09c7e80680e0d3035jpeg.jpg" alt=""><figcaption>Aerial images of house roofs with urban farming in Bhakteshwar, Banepa.</figcaption></figure><figure><img width="1412" height="933" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20230112100128/63bfd2c49c7e80680e0d3036jpeg.jpg" alt=""><figcaption>Photo: GEOMATICS ENGINEERING SOCIETY, KATHMANDU UNIVERSITY</figcaption></figure>“We initially identified buildings, studied their types and shapes,” says Sushma Ghimire, a geospatial analyst. “Then we identified flat roofs and their types and created a database of the six wards in the municipality. Using OpenStreetMap, we have digitised every building footprint.” The research and database in Banepa could serve as a way forward in urban agricultural planning and policy-making that newly-elected local governments could implement. Locals like Bijaya Manandhar are on the frontlines of this research, since it is her expertise in farming that will make or break the experiment.  The project has the full support of Banepa’s newly-elected municipal officials, who have allocated a budget line for urban farming. Deputy Mayor Bimala Sapkota says: “To help rooftop farmers we will also distribute compost bins to turn kitchen waste into fertiliser and also train them in rainwater harvesting techniques.” <figure><img width="895" height="1012" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20230112100128/63bfd2c89c7e80680e0d3037jpeg.jpg" alt=""><figcaption>Maps showing temporal urban change in six wards of Banepa Municipality since 2000. Photo: GEOMATICS ENGINEERING SOCIETY, KATHMANDU UNIVERSITY</figcaption></figure>The OSM and geospatial data have also helped identify areas with water shortage by presenting a detailed overview of roofs and water tanks available in houses spread across different wards: for instance, the maps have shown an absence of rooftop tanks in Ward 7, indicating water scarcity. At Kanthu Tole, farmers use plastic bags, pots and styrofoam as containers to grow food on, and Narayan Thapa of the Geometrics Engineering Society says farmers can also experiment with vertical farming to increase the area under cultivation. Researcher Rehana Shrestha is confident that the project will infuse a new passion for rooftop farming, especially among younger members of households.“Projects like this provide opportunities for the empowerment of youth, cultivating a generation of young leaders, to create resilient communities,” she says. “And with climate-induced disasters, urban farming is more necessary than ever.” Read more: <a href="https://www.nepalitimes.com/banner/four-years-later-nepal-farmers-rise-from-the-rubble/">Four years later, Nepal’s farmers rise from the rubble</a>, Lisa Choegyal

Rooftop agriculture on the roof of the world

<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221207101212/639059869c7e80680e0ce1f3jpeg.jpg" alt="" width="1139" height="640"/><figcaption>All photos: GOPEN RAI</figcaption></figure>Over the last decades, Nepal’s socio-political transformation has led the country from an agriculturally-dependent rural nation to a country with expanding urban spaces.Although rural Nepalis are still dependent on farming, the contribution of agriculture to the country's economy has shrunk to 25%, while the expansion of banking, telecommunication, trade and other service sectors has been rapid.The Kathmandu Valley has nurtured 2,000 years of civilisation and culture, and is among the oldest and largest cities south of the Himalaya. Its thriving non-agricultural economic activity remained the one true Nepali urban centre for much of the country’s history -- to the extent that citizens outside of the city called it ‘Nepal’ in the past, considering the city a nation unto itself.The evolution of most cities outside the valley has emerged as a relatively new trend, after the expansion of trading centres along Nepal’s southern border following the extension of railway lines in north India by the British towards the end of the 19th century. Subsequently, cities in the hills — like Tansen, Dhankuta and Pokhara — emerged after the establishment of state administrations.However, access to road infrastructure like the East-West highway — which facilitated an increase in economic activity as well as migration from the central hills to the fertile southern plains—played a significant role in the establishment of major cities like Hetauda, Narayangad, Damak and Mahendranagar.But as many cities as there are now, most of them share similar characteristics: unorganised settlements, improperly managed urban infrastructure, and unequal access to opportunities. Urban planner Jagdish Chandra Pokharel says, "Nepal’s cities are chaotic because an adequate inclusive blueprint to make them liveable does not exist, and cities have little urban character to them because expansion often takes place without planning."Rather than urbanisation, Pokharel adds, there has been a “ruralisation of cities”.In the 2017 Nepal Labor Force Survey conducted by the Central Bureau of Statistics, 36.2% of respondents said that their residence was different from their place of birth, showing an increasing trend of internal migration. There were only 16 urban centres across the country according to the 1971 census, and Nepal’s urban population was 3.6%. Kathmandu was the only city with a population of more than 100,000, while only five other cities recorded a population of more than 20,000.But migration to the Tarai expanded in the 1970s, and more cities formed. By the time Nepal became a democracy in 1990, the market centres of the Madhes were connected to the hills, and the urban population expanded rapidly.<img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221207101212/639059899c7e80680e0ce1f4jpeg.jpg" alt="" width="961" height="640">Nepal’s urban population growth rate grew almost three times in the last decade of the 20th century, and beyond. Fifty years after the 1971 census, data from the 2021 census puts the number of cities with a population of more than 100,000 at 39, most of them in the Tarai where urbanisation is concentrated.Even as internal migration has impacted the evolution of cities in Nepal, foreign employment has also had a hand on where Nepalis have settled. Nepal’s lahure, who returned from the British Army, began to resettle in cities in the 1970s, leading to an increase in population density in cities like Dharan, Pokhara, Bhairawa and Kathmandu.In the 1990s, Nepalis began leaving in droves to work in foreign countries other than India, changing the socio-economic dynamic of the country. This resulted in remittance income changing production, consumption and lifestyle of Nepalis, enabling rural families to migrate to urban hubs in search of better education and healthcare.Moreover, the decade-long armed insurgency also contributed to in-migration as Nepalis began to move away from rural Nepal— mostly to district headquarters and to Kathmandu. Subsequently, the second People’s Movement centralised Kathmandu’s power.The World Bank's 2016 Moving Up the Ladder, Poverty Reduction and Social Mobility in Nepal report states that Nepal's urbanisation is the fastest in South Asia, with the urban population expansion outpacing its 4% increase in annual GDP growth in the last few decades.The federal restructuring turned many of Nepal’s villages into municipalities without any clarity as to the economic criteria for changing the status of local administrative units. This means that 66% of Nepalis now live in cities, according to the 2021 National Census, and a significant number of the municipalities do not have urban characteristics.Across the world, cities are defined on the basis of population density, access to infrastructure, and the existence of a non-agriculture economy. Indeed, even Nepal’s National Urban Policy, 2007, stipulates that in order to be declared an ‘urban area’, the population density must be at least 10 people per hectare with more than half of the population engaged in non-agricultural activities. However, most of Nepal’s new cities do not meet that criteria.Urban planner Mahendra Subba argues that in Nepal, cities are declared on the basis of political decisions rather than any scientific procedure, and the policies are as ambiguous as they come. The National Urban Development Strategy 2017, states that the urban system in Nepal is imbalanced, with poor urban infrastructure, and inadequate standards.Adds Subba: "Water supply management, safe roads, quality housing, clean air, sufficient open space and waste management are important challenges to address.”<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221207101212/6390598c9c7e80680e0ce1f5jpeg.jpg" alt="" width="1586" height="1126"><figcaption> </figcaption></figure>Ruralisation of KathmanduThere is no better example to observe the flaws of urbanisation in Nepal than Kathmandu. Unsafe roads, polluted air, unmanaged traffic, inconvenient public transport, insufficient drinking water, garbage, and sewage mismanagement have become characteristic to the concrete jungle that is the capital.This disorganisation has not only taken away from the aesthetic of the city, but also increased disaster risks of earthquakes, floods and fire. Kathmandu is a city of villages.Access to water is at the top of Kathmandu’s problems. While global standards stipulate an individual have access to 120 litres of water daily, Kathmandu residents have less than half that amount.  In fact, Kathmandu’s population needs more than 450 million litres of water a day, but the supply does not amount to even a quarter of that. Even the Melamchi water supply project, which will bring 170 million litres of water per day, will not be enough to address Kathmandu's water shortage. The capital’s traditional Malla-era stone spouts have dried up due to haphazard urbanisation.Access to infrastructure is another problem. The city has become a maze of hazards navigable only by the rich and the able-bodied. Kathmandu has no organised roads for pedestrians, nor does it have disability-friendly structures. Even basic requirements like zebra-crossings are not maintained, leading to the deaths of dozens of pedestrians, including that of a Nepali diplomat right in front of the Singha Darbar recently.On the other hand, uncontrolled increase in the price of real estate is reducing access to housing for middle and low income citizens in urban centres. The nexus of banks, land dealers, investors and the government have monopolised land ownership in Kathmandu as well as cities across Nepal. Urban poverty and squatter settlements have increased.Urban planner Upendra Sapkota says that if affordable housing is not provided by the government and non-government sectors in cities including Kathmandu, squatter settlements will increase in the future. "Private housing companies should set aside at least 20% of their construction for affordable housing for the poor,” he adds.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221207101212/6390598f9c7e80680e0ce1f6jpeg.jpg" alt="" width="2250" height="1312"><figcaption> </figcaption></figure>Moving to the cityThe transformation of villages to cities is happening worldwide, and people have been leaving villages for cities for ages. The urbanisation of Nepal is therefore not a surprise, and may even be essential to raise living standards.“Urbanisation is not bad, but it is important to pay attention to what kind of urbanisation is taking place,” says urban planner Jagdish Chandra Pokharel.Increasing greenery and electric vehicles to reduce pollution, managing accessible and disaster-friendly housing to low-income Nepalis, and ensuring an inclusive space for Nepalis of all socio-economic backgrounds could be immediate steps to make cities more liveable.Systematic urban development also increases the ties of cities to villages, facilitating development in rural areas. Experts add that urban expansion is the right path to increasing access to infrastructure and socio-economic services in Nepal’s villages, which will go on to create opportunities and curb migration.“We should think about how to connect urban centres with villages so that facilities are extended to rural Nepal as well,” says another urban planner, Saroj Basnet.In recent years, discussions about urbanisation have extended to 'Smart Cities' and 'Satellite Cities'. However, there is no clear blueprint for building such a city, and discourse remains limited to political announcements.The National Urban Development Strategy has pointed out the need for additional investment of more than Rs12 trillion to build infrastructure in just 217 municipalities. By the year 2031, this need will reach Rs36 trillion.Mahendra Subba adds: “Although municipalities are legally entrusted with the responsibility of urban expansion, the technical, administrative and financial capacity of local units is not up to par." Indeed, even though the government has announced the creation of 10 big cities, there has been no real discussion or preparation regarding investment, availability of resources, or need.“Our urban policies have failed to address how to mobilise and distribute available resources to build smart cities,” says geographer and regional planning expert Pitambar Sharma, adding that cities cannot be built on political pronouncements alone.

And climate change is not just making the world hotter, but also wetter. For every 1°C rise in temperature, there is 7% more moisture in the atmosphere.This is called ‘<a href="https://www.nepalitimes.com/banner/the-heat-is-killing-us/" target="_blank" rel="noopener noreferrer">wet-bulb temperature</a>’ that measures both ambient air temperature and humidity level to determine how hot it actually feels. For example, if it is 30°C with high humidity, it will feel much warmer. A wet-bulb temperature of 35°C is considered the maximum limit of heat and humidity that humans can handle. Beyond that, the body can no longer effectively cool itself via perspiration. A couple of hours of exposure to this without artificial cooling will mean that people will start dying of heatstroke and dehydration, with children and the elderly being the most at risk.“The climate crisis in the Himalaya is <a href="https://www.nepalitimes.com/editorial/women-and-water/" target="_blank" rel="noopener noreferrer">the water crisis</a>. Heat stress is manageable as long as there is access to water, but that is not the case for the poorest in the Tarai,” says climate scientist Binod Pokharel. “Luckily, this week’s heat wave is mostly dry heat with lower humidity.”The rain that is forecast for Nepal from Thursday will cool things down, but it will also increase the humidity.  <figure><img width="1500" height="527" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221114111152/63721e389c7e80680e0bd533jpeg.jpg" alt=""><figcaption></figcaption></figure>The other factor making heatwaves more intense are densely populated cities of vehicle exhaust, concrete and asphalt which form what are called ‘<a href="https://www.nepalitimes.com/opinion/preparing-for-kathmandus-heat-waves/" target="_blank" rel="noopener noreferrer">urban heat islands</a>’.  Ironically, the air conditioners city dwellers use to cool themselves indoors, is making it hotter still outside. There is a significant temperature gradient between the outskirts and Kathmandu’s city centre even in winter, which means the Valley does not have its characteristic winter fog anymore. On any given day, there is a temperature difference of 1.5°C  between Chobhar and Teku, even though the two places are only 3km apart.As more and more <a href="https://www.nepalitimes.com/here-now/kathmandu-loses-its-open-spaces/" target="_blank" rel="noopener noreferrer">open spaces</a> are built over and the greenery disappears, Kathmandu’s ‘heat bubble’ is going to get bigger.

And if that house is in Kathmandu Valley, then you have really made it.You might have a stable job and family, but unless you have a roof over your head that you own you are not settled by society standards. It could be a small house and the tiny plot, as long as it is yours.<a style="font-size: 15px; letter-spacing: 0.01em;" href="http://archive.nepalitimes.com/news.php?id=15757#.YfSXGS2B2t8" target="_blank" rel="noopener noreferrer">Owning a house</a> is part of our everyday conversation in households. There is always someone talking about how they are building their house, how there is no water coming out of an expensive bore well, how a neighbour built a multi-story structure and blocked out all the sunlight.Homes hold a special place in our society that very few other things can match and it is reflected in our numbers too.Nepal may lag in several economic and human development indicators, but when it comes to home ownership rates, it is far ahead of the rest. Some 85% of Nepali households live in homes they own. Proportinately, more people in Nepal own the houses they live in than in the US, UK, and Germany.Most other countries with higher home ownership rates than Nepal, such as Singapore and Russia, were able to achieve it due to their strong social housing programs. The fact that so many Nepali families own their <a href="http://archive.nepalitimes.com/news.php?id=6200#.YfSXGS2B2t8" target="_blank" rel="noopener noreferrer">own houses</a> with little governmental support is remarkable. Nepalis prize homes as their most important investment.But even with this high home ownership rate, thousands of new houses are built every year, feeding <a href="https://www.nepalitimes.com/here-now/the-vanishing-land/" target="_blank" rel="noopener noreferrer">the urban sprawl</a>. New apartments and housing projects come up to address demand.And yet, there are never enough houses to meet that growing demand. More and more cultivable agricultural land and green space are being turned into housing plots.Economically, it makes more sense for Nepalis to own their own house, even if it is at the very edge of the city. Unlike wealthier nations where buildings generally follow a standard national code for health and safety, most homes in Nepal function as isolated and self-sufficient units.Germany, for example, has laws that require housing units to have regular access to <a href="https://www.nepalitimes.com/banner/getting-our-shit-together/" target="_blank" rel="noopener noreferrer">water and sewage</a>, Nepal has no such centralised directive. A house in a Berlin neighbourhood will have roughly the same level of access to water and garbage collection as the one next to it.A house in one Kathmandu neighbourhood may have a running water and sewage system, but only if the owner is able to drill for water and have a septic tank.In the US, if landlords build a house with cheap construction materials and endangers the lives of tenants, they can be taken to court and prosecuted. In Nepal tenants are completely dependent on the whims of the landlord.So, it makes sense that people would want to move into their own house where they can make their own choices rather than live under the tyranny of someone else.Even if the landlord is agreeable and the living environment acceptable, renting is not a long-term, financially sound solution. Given how the rents have soared in the cities, it makes more economic sense to build one’s own home.Houses in Nepal are not just places of shelter, but also of income. Owning a house doesn’t just save rental money it can also earn rental cash. In a country with very few mature investment opportunities, a home is a nest-egg. Many Nepali families sell off their homes in times of acute need: to send a family member abroad, pay hospital bills or marry off children.Homes become important at festival time, and Nepali culture places a lot of emphasis on communal gathering and cooking, all things that are more conducive in personally owned houses.Nepal has always had a <a href="https://www.nepalitimes.com/here-now/ground-reality-of-landlessness-in-nepal/" target="_blank" rel="noopener noreferrer">historical home-ownership culture</a>. Until very recently, most of Nepal’s population lived in rural areas where land is plentiful and houses are built with local materials. There were few constraints on building and owning a home. Houses were within the reach of many people, creating a cultural legacy towards home ownership that has persisted.Ultimately, there is a universal and innate desire to own your own home.  In archaeological remains all over the world, we see human settlements created with a meticulous level of care.From the earliest cave paintings, humans have been decorating and creating a material environment. Building technology may have advanced, but this fundamental human desire to elevate personal space from a place of rest to one with meaning has not changed.Homes are where we spend the most time, they are where we create memories. They are an extension of ourselves. How they are built and look end up becoming a reflection of how we think, act and behave. That is why we seek to permanently own this extension.By owning our own house, we give ourselves more freedom. In the end, home is where the heart is, and who would not want to own their own heart?Avani Adhikari is a student of Economics and Urban Planning in Singapore.

People wait year-round to escape the otherwise dull and dusty concrete landscape with a vibrant streets of purple, red and green. But very few people know that these beautiful roadside trees and their colourful seasonal flowers are ill-advised for our climate, and can increase road hazard. Trees shelter us from sudden downpours, and during hot summer days, we seek their refreshing shade. In fact, they reduce the temperature of the asphalt surfaces beneath them by as much as 15° Celsius.  Trees purify the air by sequestering carbon dioxide and giving off oxygen, they remove harmful gases and particulate matter. They improve the soil by assisting in nutrient cycling and help regulate surface and subsurface water. And they provide food and shelter to insects, birds, animals, and plants.However, not all trees are suitable for urban streets. We need to select them based on more than aesthetics and convenience. Ecological value and road hazards are equally if not more important considerations when choosing a species.Unfortunately, past strategies and the recent <a href="https://www.moud.gov.np/storage/listies/July2019/NUDS_PART_A.pdf" target="_blank" rel="noopener noreferrer">National Urban Development Strategy 2017</a> and <a href="http://dudbc.gov.np/uploads/default/files/ae0b4f05ccb43bd80c1e5c39e3f69267.pdf" target="_blank" rel="noopener noreferrer">Nepal Urban Road Standard 2076</a> have failed to provide clear guidelines for tree selection, leading to haphazard planting along Kathmandu’s roads. Concerns raised by ecologists, conservationists and locals over the years have gone unheard.History of street treesEarly records of roadside trees date back to the 14th century when Jayasthiti Malla (1380-1395) ordered plantations alongside streets and public wells. Later, Prime Minister Jung Bahadur Rana, brought back exotic species like Eucalyptus, bottlebrush (Callistemon), and Kaiyo ful (Grevillea robusta) from his Europe visit (1850-51) to decorate palaces and roadsides. <figure><img width="1000" height="700" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141148/636d01bc9c7e80680e0a3642jpeg.jpg" alt=""><figcaption> </figcaption></figure>More systematic efforts started in the early 20th century. Prime Minister Chandra Shumsher Rana (1901-1929) expanded Kathmandu’s road network and planted trees, introducing new species like Monkey puzzle (Araucaria araucana). Juddha Shumsher Rana (1932-1945) continued planting trees to beautify the roads like Putali Sadak, particularly after the devastation of the 1934 earthquake.Modern urban environmental planning began during the Panchayat in the 1960s and 1970s. The government renovated roads, mandating the planting of either a single line or double line of roadside trees. Part of the newly constructed Arniko Highway (Kathmandu to Kodari) and the Ring Road encircling the capital, had rows of trees on either side. In the 1980s, urban planners suggested three lines of green belt alongside the roads instead of previously mandated one-line roadside trees. As a result, more than a hundred thousand fast-growing trees were planted around the Ring Road.Rana and Panchayat planners were wrong to pick roadside trees such as poplars and eucalyptus based primarily on aesthetics and their fast-growing nature. In recent decades, Nepal has been steadily expanding its road network while integrating green belts, but planners have neglected the inclusion of criteria on species selection.Over time, attempts have been made to suggest a more scientific species selection. <a href="https://doi.org/10.3126/banko.v15i1.17042" target="_blank" rel="noopener noreferrer">Researchers</a> have recommended over 300 potential species for urban forestry in Kathmandu, including a comprehensive list of suitable species that could be planted alongside roads. The list includes native and exotic trees and ornamental plants. These suggestions have been largely ignored.Mitra Pathak, research officer at the National Botanical Garden in Godavari says, “It is unscientific, we are planting whatever saplings are easily available.”Ecologically, the majority of trees planted around Kathmandu are misfits. Swami (Ficus benjamina) for instance is a weed, whilst Grevillea robusta, a deciduous branchy species, and Raj Sallo (Cupressus torulosa), are climatically unsuitable for the city.Urban environment expert Ramji Bogati also laments the lack of ecological criteria. “We should take into account factors like location, soil, nature of the species, in selecting roadside trees,” he says. <figure><img width="1500" height="1125" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141148/636d01be9c7e80680e0a3643jpeg.jpg" alt=""><figcaption> </figcaption></figure>The <a href="https://www.researchgate.net/publication/342699040_Diversity_and_Species_Selection_in_Urban_Forestry_Reflection_from_Maitighar_to_Tinkune_Road_of_Kathmandu_Valley_Nepal" target="_blank" rel="noopener noreferrer">Tinkune-Maitighar Road</a>, for example, is one of Kathmandu’s better-maintained green belt stretches. But despite having high species diversity, proper tree species selection has been disregarded. Planners mainly opted for exotic species that grow fast, with minimum care, and with a high survival rate instead of evergreen and local species. The 3.2 km road with four rows of plants consists mostly of non-native ornamental trees: fast-growing deciduous poplars, eucalyptus which lowers the groundwater table due to fast moisture absorption, and Jacaranda mimosifolia, an invasive species. Poplar and eucalyptus can damage foundations and develop cracks in pavements because their roots grow close to the soil surface. Some native species planted, such as birch (Betula alnoides) and silk tree mimosa (Albizia julibrissin), both deciduous and fast-growing, were poor choices owing to their open crown and drooping branches that are potential road hazards. Willow (Salix babylonica), native to central Asia, on the other hand, is a better choice because it is elegant, robust and tolerant to air pollution and injuries.Guides to roadside tree selection<a style="font-size: 15px; letter-spacing: 0.01em;" href="https://tid.p3.gov.np/wp-content/uploads/2019/06/Nepal-Road-Standard-2070.pdf" target="_blank" rel="noopener noreferrer">Nepal Road Standard 2070</a> has three guidelines for roadside plantations: ensure good visibility by planting trees on sides and shrubs on the median, avoid wide-crowned trees, and ensure tree crowns do not cross the pavement's edge. Yet, even this fails to address important aspects of species selection. In particular, we need criteria to evaluate ecological, economic, and aesthetic values. <figure><img width="2056" height="1286" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141148/636d01c19c7e80680e0a3644jpeg.jpg" alt=""><figcaption> </figcaption></figure><ol><li>  Functional Criteria:Block noise, clean the air, control wind and provide safety and shade to vehicles and pedestrians, and habitat for urban wildlife.</li><li>  Ecological Criteria:Fitting for the soil and climate of the city, resistant to wind, pests, diseases and air pollution.</li><li>  Socio-Economic Criteria:Cost, care, longevity, and reflection of urban identity.</li><li>  Structural Criteria:Fast development, pruning-ability, strong root system, tree shadow, flowering and fruiting, future size, and diameter.</li><li>  Visual Criteria:Colour of leaves, flowers, deciduous vs. evergreen, tree dimension, road width, and planting arrays.</li></ol>Selecting appropriate tree species is often complex but if we engage urban planners, ecologists, and specialists of the field, we can create sustainable roadside plantation guidelines. <a href="https://www3.diism.unisi.it/~mocenni/Note_AHP.pdf" target="_blank" rel="noopener noreferrer">Analytic Hierarchy Process (AHP)</a> is an effective tool to aid decision-makers to set priorities and decide the most suitable trees for particular roadside ecologically and aesthetically.We have to be cautious with the types of trees to plant along our roads, beauty can often be misleading. Carefully selected roadside trees can help reduce negative environmental and social impacts of urbanisation, making Kathmandu more resilient in the face of changing climate and overexploitation of nature.Meena Bohara, PhD, is a researcher of ecology and environment.

When it was first turned into a landfill site in 2006, the KMC proposed to use it only for three years but 17 years later, 75% of about 1,200 tonnes of daily <a href="https://www.nepalitimes.com/banner/the-covid-19-plastic-pandemic/" target="_blank" rel="noopener noreferrer">waste generated in Kathmandu Valley</a> ends up here in Nuwakot.Under normal circumstances, up to 200 vehicles dump the waste in Sisdole daily, which is later pushed around the site by an excavator at a height of about 200 meters.“Back then the government had acquired our land for the site, we were promised jobs,” says Bimala Balami. “But they were distributed unfairly. Some people here receive annual grants from the government but others don’t even get a penny.”<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141144/636d00e09c7e80680e0a35fejpeg.jpg" alt="" width="1500" height="1000"><figcaption></figcaption></figure><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141144/636d00e39c7e80680e0a35ffjpeg.jpg" alt="" width="1500" height="1000"><figcaption></figcaption></figure><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141144/636d00e79c7e80680e0a3600jpeg.jpg" alt="" width="1500" height="1000"><figcaption></figcaption></figure><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141144/636d00ea9c7e80680e0a3601jpeg.jpg" alt="" width="1500" height="1000"><figcaption></figcaption></figure>Rapid and unplanned growth coupled with poor municipal management has meant that <a href="http://archive.nepalitimes.com/article/Nepali-Times-Buzz/Kathmandu-waste-management-problem-solution,1416" target="_blank" rel="noopener noreferrer">Kathmandu has always had a garbage problem</a>. Kathmandu needs another landfill site and the proposed alternative Banchare Dada, 1.9km west of Sisdole, has been under construction for years.The Ministry of Urban Development had signed a contract with Lumbini Koshi and Neupane JV in April 2019 to complete the work at <a href="https://www.nepalitimes.com/banner/what-will-nepal-do-with-its-e-waste/" target="_blank" rel="noopener noreferrer">Banchare Dada</a> within a year.

Unfortunately, the main obstacles to a solution have remained the same for the past five decades.”

The Covid-19 lockdowns devastated the economy, the 2020 monsoon killed a record number of people, and this year the second wave hit with full force even as governance was paralysed by a prolonged power struggle in the ruling party. Now, Nepalis are bracing themselves for their <a href="https://www.nepalitimes.com/here-now/preparing-for-floods-during-a-lockdown/" target="_blank" rel="noopener noreferrer">second monsoon season during the pandemic</a>, one which meteorological modellers say could dump above normal precipitation over most parts of the country.The other difference with last year is that the second Covid-19 wave is even more virulent and widespread. This means crowded shelters after a flood or landslide will be hotspots for new infections at a time when only 4% of the population is vaccinated.“Covid and floods are contradictory in nature, as one needs physical distancing while the other makes it impossible to do so. This will add to the existing burden,” says epidemiologist Lhamo Yangchen Sherpa.She adds: “We can’t prevent floods, but we can reduce its impact. We must concentrate on identifying risk groups and their emergency evacuation, set up shelters with physical distancing, stockpile tents, food and emergency medicines including oral rehydration salts and water purifiers.”Even though last year’s southwest monsoon was said to be 'normal' in Nepal, it <a href="https://www.nepalitimes.com/here-now/deadly-monsoon-in-nepal-turns-deadlier/" target="_blank" rel="noopener noreferrer">triggered numerous flash floods and landslides</a>, killing at least 400 people and destroying over 1,000 houses. Entire villages in Sindhupalchok, Jajarkot, Myagdi, Baglung, Kalikot and Bajura districts were buried. The South Asian Seasonal Climate Outlook Forum (SASCOF) has forecast ‘above normal’ rainfall for most of Nepal this year, with more than usual precipitation in most of the Mahabharat and Himalaya, and slightly deficient rainfall in the eastern Tarai. <figure><img width="2081" height="1260" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109121140/636b92019c7e80680e06f122jpeg.jpg" alt=""><figcaption> </figcaption></figure>"There is a possibility of floods, landslides and other water-related disasters occurring together during the third and fourth week of July this year when the second wave of the pandemic will still be peaking,” states the government’s National Monsoon Preparedness and Response Plan 2021. The probability of flash-floods and landslides are even higher this year because of <a href="https://www.nepalitimes.com/banner/nepal-is-going-up-in-smoke/" target="_blank" rel="noopener noreferrer">the wildfires</a>. There were 7,000 fires affecting 75 of Nepal’s 77 districts from November 2020 to May 2021, the highest number ever recorded.  The fires reduced forested slopes to ashes, incinerated the undergrowth, thus reducing the absorptive capacity of the soil. When the rains come, the water will therefore rush down the slopes instead of seeping into the topsoil. “This year’s rainfall is forecast to be higher than last year's average. Based on this analysis, it can be estimated that there will be a significant increase in <a href="https://www.nepalitimes.com/here-now/in-nepal-either-too-much-or-too-little-water/" target="_blank" rel="noopener noreferrer">landslides and floods</a> during this year's monsoon,” says meteorologist Shanti Kandel at the Department of Hydrology and Meteorology. She adds: “Forecasting is preparedness in some ways. But it has to be effectively communicated, so if we are to wait until landslides have occurred to act, it’s too late and there is no point.” <figure><img width="1050" height="701" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109121140/636b92049c7e80680e06f123jpeg.jpg" alt=""><figcaption> </figcaption></figure>In the past, <a href="https://www.nepalitimes.com/banner/disastrous-management-in-nepal/" target="_blank" rel="noopener noreferrer">the government has faced criticism</a> for prioritising relief over prevention. This could change with the formation of the National Disaster Risk Reduction and Management Authority (NDRRMA), which works primarily on preparedness and mitigating risk, while delegating more rescue responsibility to first-responders in local governments.“In earlier years landslides were not discussed as part of our monsoon preparedness plan, only floods were, and this year we set landslides as a priority for preparedness and response also looking at the intersection of wildfires, Covid-19 and the monsoon,” says Anil Pokhrel, who heads NDRRMA that has produced a workplan for monsoon preparedness and response. The NDRRMA with DHM recently trained officials in 36 municipalities in nine of the most high-risk districts (Myagdi, Gorkha, Kalikot, Rasuwa, Sindhupalchok, Bajhang, Jajarkot, Syangja and Dailekh) on Impact Based Forecasting which predicts extreme weather events so that at-risk groups can be ready. “We are dealing not just with floods and landslides this time, but also Covid-19. Local communities are setting up rapid response teams to best prevent an outbreak in shelters and maintain health protocols, and spreading awareness through FM radio in local languages,” says Liladhar Adhikari of the NDRRMA. Despite the ‘above normal’ forecast in the models, climate scientist Ngamindra Dahal expects the monsoon to even out unless Nepal experiences cloudbursts over the Mahabharat and Chure ranges. These sudden heavy showers have been the cause of the deadliest floods and landslides in recent years. “We now have the technology to predict localised cloudbursts through Impact Based Forecasting which is crucial in saving lives, all we need now is real-time action so local communities get advance warning,” says Dahal.But predicting and determining the impact of floods and landslides only from the perspective of weather gives us an incomplete picture. The climate crisis has changed precipitation patterns and made extreme weather events more frequent and destructive. <a href="https://www.nepalitimes.com/here-now/dont-just-blame-god-for-floods-and-landslides/" target="_blank" rel="noopener noreferrer">Poorly designed and built roads, bad engineering</a>, and unplanned settlements have disturbed fragile mountain slopes, making them more disaster-prone.“We have in recent times recorded 105mm rain per hour in Surkhet, 100mm in Bajhang and 73 in Kulekhani which is a clear indication that the monsoon is getting more intense, but we are only now trying to understand this trend,” says Dahal. “We need to see whether there are indeed more frequent cloudbursts, or if the disasters are more noticed because they affect new settlements in floodplains and roads that follow river banks.” <figure><img width="1174" height="770" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109121140/636b92079c7e80680e06f124jpeg.jpg" alt=""><figcaption> </figcaption></figure>At the NDRRMA, Liladhar Adhikari agrees that in addition to rapid response and rescue, a new development model is crucial in preventing multiple hazards in the long term. “New infrastructure has to adhere to environmental safeguards so that they do not drastically alter the rural landscape and make them more vulnerable to disasters.”Unfortunately, Nepal’s approach to development has been at the expense of nature preservation. The annual budget announced last week <a href="https://www.nepalitimes.com/here-now/the-nature-of-pandemics/" target="_blank" rel="noopener noreferrer">will allow quarrying</a> on the already-unstable slopes of Himalayan foothills to export stones and aggregates to India.Epidemiologist Lhamu Yangchen Sherpa has been to several emergency shelters recently, and points out that there is an <a href="https://www.nepalitimes.com/opinion/uneven-pandemic-impact-on-nepali-women/" target="_blank" rel="noopener noreferrer">additional burden on women during disasters</a>.  She says: “Like before and during this coronavirus crisis, women are especially vulnerable in the aftermath of a disaster, we must support them with security in shelters, physical and mental health care during this monsoon in the middle of a pandemic.”

Nepal braces for monsoon-pandemic double hit

Across the world and in Nepal, poets and singers have waxed eloquent about the blinking light of the nocturnal insects.But for <a href="https://www.nepalitimes.com/banner/the-fading-light-of-nepals-fireflies/" target="_blank" rel="noopener noreferrer">a creature so admired</a>, there has not been much of an effort to study and protect them. As elsewhere in the world, firefly numbers have declined sharply, even prompting the International Union for the Conservation of Nature (IUCN) to set up a Firefly Specialist Group in 2018.“We grew up playing with fireflies, chasing them around Tundikhel, but those days are long gone,” laments Tirtha Bahadur Shrestha, a noted Nepali naturalist. “Fireflies need a pristine environment, and their very presence signifies undisturbed nature.”Fireflies belong to a family of beetles called Lampyridae and evolved alongside dinosaurs 100 million years ago. But habitat destruction, <a href="https://archive.nepalitimes.com/article/nation/pesticide-laced-vegetables-continue-to-poison,1555" target="_blank" rel="noopener noreferrer">rampant pesticide use</a>, light pollution and climate change now threaten to put the lights out on all 2,200 species of fireflies so far identified.Read also: <a href="https://www.nepalitimes.com/banner/between-existence-and-extinction-in-nepal/" target="_blank" rel="noopener noreferrer">Between existence and extinction in Nepal</a>, Sonia AwaleThe decline of fireflies indicates a degradation of the ecosystem, <a href="http://archive.nepalitimes.com/news.php?id=18976" target="_blank" rel="noopener noreferrer">especially of wetlands</a>. Yet, there has been no systematic study of the status, scope and habitat of these glow worms  in Nepal.“The number and diversity of firefly species are unknown in Nepal and researchers have not given priority to these insects,” says Hum Gurung of Singapore-based Birdlife International Asia, who is promoting firefly tourism in Malaysia, and developing a participatory citizen scientist group to study fireflies in Nepal.Gurung says firefly conservation must begin with first researching them and planning a sustainable eco-tourism model based on firefly viewing, just like the cherry blossom season in Japan or fall colours in New England.“Their commercial value will add to the efforts to protect them,” he adds.But in Nepal, these lightning bugs that were once ubiquitous in gardens, jungles, riverbanks, and even streets and playgrounds in the towns have all but disappeared. Where did they all go?In Pokhara, butterfly researcher Surendra Pariyar says: “I have nostalgic memories of fireflies from my childhood, but as the city’s concrete jungle spreads I hardly see even one firefly these days.”Read also: <a href="https://archive.nepalitimes.com/page/what-is-the-buzz" target="_blank" rel="noopener noreferrer">What's the buzz?</a>, Sonia AwaleElsewhere in Japan, Southeast Asia and South America, the charismatic beetles with their bioluminescent courtship displays have turned into a major attraction for nature and wildlife tourists.Extra income from the firefly boat tours was crucial in curbing overfishing in Malaysia’s Kuala Selangor. Fireflies can promote unique, insect-based <a href="https://www.nepalitimes.com/banner/nepals-other-attraction-the-night-sky/" target="_blank" rel="noopener noreferrer">night tourism</a> with indigenous communities in Bardia and Chitwan in Nepal.Says butterfly expert Bhaiya Khanal, previously with the Natural History Museum: “Firefly tourism opens up a lot of opportunities including the possibility of finding more species. This, in turn, will promote their conservation.”Artificial light however is the biggest threat to fireflies as it reduces the beetle’s breeding success. Bright lights from buildings, vehicles, flashlights, and even cell phones can disrupt firefly mating.Nurturing and protecting the habitat is equally important, especially as the bugs spend most of their life cycle in a larval stage and require several months or even up to three years, to develop into adults.“We need to understand their lifecycle and its role in the ecosystem, what it feeds on and what preys upon them and our conservation and ecotourism efforts should take all of these into account,” adds Tirtha Bahadur Shrestha.Fireflies can be a ‘gateway bug’ to get tourists and locals interested in conserving many other insects, often ignored in favour of tigers, rhinos and wild elephants. Nepal is a model for wildlife conservation but its efforts in protecting smaller organisms are nearly non-existent.But first, proper conservation mechanisms must be put in place so that spreading firefly tourism does not end up destroying the very insect it is trying to save.<a style="font-size: 15px; letter-spacing: 0.01em;" href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/csp2.391?utm_source=mp-fotoscapes" target="_blank" rel="noopener noreferrer">A new study</a> published in the journal Conservation Science and Practice provides the first comprehensive review of the geographic scope, magnitude, focal species, and other attributes of the major firefly tourism sites worldwide.The rapid proliferation of firefly tourism could mean new threats such as inadvertent trampling of female adults and degradation of larval habitats during tours.“Ultimately we have to change our destructive development methods and work on urban planning that takes into account the health of an ecosystem,” adds Hum Gurung, also co-author of the paper.Bhaiya Khanal agrees that conservation and development should go hand-in-hand. He says, “New infrastructure projects must not ignore these creatures, we must proactively protect them before they are forever gone.”<h2>What makes them glow?</h2><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111156/636cd96e9c7e80680e092e9djpeg.jpg" alt="" width="1280" height="850"><figcaption> </figcaption></figure>Fireflies have a romantic morse code for every occasion, whether it is to find a mate, or to scare off predators. It could be a steady glow or a flashing light, differing in duration, timing, colour, and repetition.All 2,200 identified species have their own blinking codes, glowing to varying degrees during the larva stage but most lose their light-emitting capacity by adulthood. Fireflies are also active during the day when they use chemical signals or pheromones to attract partners.Fireflies also emit a lightning signal when threatened by predators, or to protect territory. The light comes from a chemical reaction called bioluminescence, and the glow is not hot, but cold to touch.The lower abdomen of a firefly consists of calcium, magnesium, and a naturally occurring chemical called luciferin. But it is a superoxide ion, an extra electron, that is responsible for pale yellow, green, sometimes orange or blue flickers during hot summer nights.The reaction can be harmful to living tissue, but it does not affect the insect because the reaction is contained and happens quickly. The toxic luciferin molecule could be the key to a breakthroughs in cancer research and therapy.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111156/636cd9729c7e80680e092e9ejpeg.jpg" alt="" width="447" height="285"><figcaption> </figcaption></figure><h2>Fireflies in Nepal</h2><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111156/636cd9749c7e80680e092e9fjpeg.jpg" alt="" width="2093" height="1372"><figcaption> </figcaption></figure>Only three species of fireflies have ever been recorded in Nepal, and even those were when the first British naturalists came to Kathmandu in the 1830s.Diaphanea marginellus was spotted at 2,000m in Kavre, so was Luciola ovalis. But the most common species found throughout Nepal is Luciola cruciate, pictured above.Fireflies prefer hot and humid conditions and are therefore found in the plains and the mid-mountains valleys of Nepal between July-August-- in ponds, streams, marshes and rivers. Fireflies usually are not found above 1,200m altitude, so Kathmandu would be at the upper limit of their habitat.
