Vertical Farms Grow Veggies On Site At Restaurants And Grocery Stores
The Vertical Field setup retains many of the advantages of hydroponic vertical farms, but instead of the plants growing in a nutrient-packed liquid medium, the container-based pods treat their crops to real soil, supplemented by a proprietary mix of minerals and nutrients

The Vertical Field urban farm pod can be installed in parking lots or inside warehouses, with a modular design that can grow according to customer need Vertical Field
Last month we reported that a huge vertical farming operation near Copenhagen in Denmark recently completed its first harvest. That setup uses hydroponics, but the veggies grown in Vertical Field urban farming pods take root in real soil.
Traditional agricultural farming involves the use of a lot of land and resources to grow crops, and then even more resources to harvest and transport the goods – sometimes thousands of miles – to where consumers can get to them.
As well as requiring a fraction of the growing space, controlled-environment agriculture systems such as hydroponics operations can be much more efficient, are no longer bound by season or location, the growing to harvest cycle is reduced and crops could be produced all year, and as with the Copenhagen operation, they can be set up close to where the food is purchased or consumed.
The Vertical Field setup retains many of the advantages of hydroponic vertical farms, but instead of the plants growing in a nutrient-packed liquid medium, the container-based pods treat their crops to real soil, supplemented by a proprietary mix of minerals and nutrients. The company says that it opted for geoponic production "because we found that it has a far richer flavor, color, and quality."
Vertical Field's urban farms grow walls of veggies inside recycled shipping containers
Vertical Field
"Vertical Field offers a revolutionary way to eat the freshest greens and herbs, by producing soil-based indoor vertical farms grown at the very location where food is consumed," said the company's CEO, Guy Elitzur. "Not only do our products facilitate and promote sustainable life and make a positive impact on the environment, we offer an easy-to-use real alternative to traditional agriculture. Our urban farms give new meaning to the term ‘farm to table,’ because one can virtually pick their own greens and herbs at supermarkets, restaurants or other retail sites."
The recycled and repurposed 20- or 40-ft (6/12-ft) shipping containers used to host the farms can be installed within reach of consumers, such as in the parking lot of a restaurant or out back at the grocery store. Growers can also scale up operations to more than one pod per site if needed, and the external surfaces could be covered in a living wall of decorative plants to make them more appealing.
The vertical urban farms are claimed capable of supporting the production of a wide range of fruits and veggies – from leafy greens and herbs to strawberries and mushrooms, and more. And it's reported to use up to 90 percent less water than a traditional farming setup.
"Through internal experiments with our irrigation method using data from sensors and models we have understood that this is the level of water efficiency," Vertical Field's Noa Winston told New Atlas. "Thus we arrived at an optimal irrigation protocol tailored to the needs of the plant."
According to the company's website, though pesticide-free, the system is not yet considered organic (though Vertical Field is currently in the process of attaining organic certification for the urban farm unit from the USDA). The crops also grow in a bug-free environment.
"The container is kept bug-free because it is sealed off, automated, and we limit human entry to only essential people and essential work," Winston explained. "The container farm itself is not a street vendor or a point of sale, therefore unnecessary or frequent entry does not occur."
Installing a Vertical Field urban farm in a grocery store parking lot means that consumers can benefit from fresh veggies all year long Vertical Field
Unlike some high-tech farming solutions, staff won't need special training to work with the vertical farm as the automated growing process monitors, irrigates, and fertilizes the crops as they grow thanks to arrays of sensors that continually feed data on climate, soil condition, LED lighting and so on to management software. Each vertical farm unit has its own Wi-Fi comms technology installed to enable operators to tap into the system via a mobile app.
The company told us that, by way of example, one container pilot farm offered a growing space of 400 sq ft (37 sq m) and yielded around 200 lb (90 kg) of produce per month, harvested daily. Lighting remained on for 16 hours per day. We assume that the pods are completely powered from the grid at their respective locations, though the company says that it is looking at ways to make use of solar panels as well as making more efficient use of water.
Vertical Field has been around since 2006 and has built a number of living green walls around the world since then. The soil-based vertical farm initiative was started in 2019.
Recent installations include the first Vertical Field container farm in the US at a restaurant named Farmers & Chefs in Poughkeepsie, New York, which started producing its own crops of fresh greens in mid-April 2020. Last month, following a successful pilot, Israel's largest supermarket chain, Rami Levy, signed an agreement with the company to roll vertical farms into dozens of store locations over the course of the next five years.
"The Rami Levy chain understands the social responsibility that it has for customers as related to food security and supplying the highest quality products while maintaining low prices," said the chain's Yafit Attias Levy. "Our customers bought Vertical Field's produce during the pilot and returned to purchase more. Therefore, we have decided to expand the partnership with Vertical Field to additional branches of the supermarket, and to offer fresh, high-quality, and pesticide-free produce in a way that increases shelf-life for our customers."
The Vertical Field urban farm can produce crops year round, without the use of pesticides Vertical Field
And earlier this month, Moderntrendo SRO – one of the largest agricultural distributors in Ukraine – signed up for a pilot project that will start with supermarket chain Varus, and potentially expand to other chains.
"We are extremely excited about our partnership with Moderntrendo SRO which has led to the project with Varus and will lead to more projects in the near future with more chains in Ukraine," Vertical Field's Guy Elitzur said. "One of the realizations that have surfaced during the COVID-19 crisis is the need to develop solutions that allow urban residents access to healthy food, with minimal human handling and without depending on transportation and shipping from remote locations. We are delighted to be able to provide - and expand access to - healthy, and high-quality vegetables grown right outside the consumer's door."
As well as grocery outlets and restaurants, the company sees its container-based vertical farms also being installed in hotels, universities, hospitals, and so on, in the future. The video below has more.

Taiwanese Know-How Built Vertical Farm In Rome In Just 3 Months
Taiwan, Vatican reap the harvest of smart agriculture at joint farm
Taiwan, Vatican Reap The Harvest of Smart Agriculture At Joint Farm
By Matthew Strong, Taiwan News, Staff Writer
2021/01/16
TAIPEI (Taiwan News) — Taiwan and it’s only European diplomatically, the Vatican, on Friday (Jan. 15) marked the first harvest of a joint farm focused on smart agriculture and environmental principles.
The Taiwanese-designed indoor farm sits on 60 hectares of land in southwest Rome owned by a Catholic foundation providing education and work opportunities to young refugees, CNA reported.
Taiwanese Ambassador Mathew Lee (李世明) on Friday toured the facility, which was launched by a team of engineers and agricultural experts from the island after just three months of preparations. He said the project was inspired by Pope Francis’ call for a more active response to environmental problems and climate change.
The farm uses the technique of vertical farming, in which vertically stacked shelves are used to grow plants through more efficient management of temperature, irrigation, and lighting. Less land and water are required to produce higher yields in vertical farms, and fewer fertilizers and pesticides are needed.
Friday’s tour featured a meal prepared with herbs and vegetables grown at the farm, according to CNA.

Farming Brought To New Heights
Although still in its early stages of development, urban rooftop farms have already started to attract attention
Forward-Thinking Entrepreneurs, Neighbors, And
Farmers Have Discovered A New Use For Rooftops: Farming.
By Alexandra Neag
November 5, 2020
Who said rooftops should only be used for cocktail bars and beauty spots overlooking the city?
Although still in its early stages of development, urban rooftop farms have already started to attract attention.
Statistics predict that by 2050 the population of the world will reach 9.7 billion. By the same year, the UN predicts that 68% of the world’s population will most likely live in urban areas, up from 55% in 2018. This substantial growth would imply the need for more agricultural land and more fresh products. Yet, if we consider the climate change challenge and the transport pollution that aggravates it, we are in dire need of more local farms.
There is considerable potential for space usage. There are 4.85 trillion sq ft (450 billion m2) of roof space in the US alone, but only 1% is being used. This way, local businesses could supply their greengrocers locally without the added carbon footprint of transportation.
Leveraging rooftop space in metropolitan areas is a great advantage. This would make a significant positive environmental impact. Transport of goods accounts for 12% of all agricultural emissions worldwide.
Reducing transportation costs and pollution is not the only way in which rooftop farms would be more eco-friendly. They would also improve air quality, absorb heat, and cool down the building. They also would add more of a green landscape to the concrete jungle, which is proven to have psychological benefits for people.
Healthy food would be readily available to local businesses, which would reduce the cost of transport and, therefore, the prepared food cost to customers. The urban farmers might even use fewer pesticides as the crop would not be at risk of being eaten by insects and rodents, producing more nutritious and tasty ingredients for people’s diets.
As the advantages of city farming have become more prominent, many places worldwide have started to adopt this initiative. Among them are the City Farm in Tokyo, Dakakker in Rotterdam, and Brooklyn Grange in New York City. In each of these urban farms, people have added new elements and ideas to match the local demand. In Tokyo’s city farm, they adjusted the agricultural conditions to grow soybeans, eggplants, and rice. These are traditionally the most used ingredients in the region. In New York, on the other hand, the extra space has enabled further expansion. They now also raise chicken for eggs as well as bees for honey production.
In Paris’ 15 arrondissement, we can find the biggest rooftop farm. They went a step further and created a soil-free system where fruit and vegetables are grown on vertical columns using coconut fibre. Their model seems to be the most fructiferous, sustainable, and clean so far. As a result, they started offering a consultancy worldwide to help other city farmers start such productive and eco-friendly agriculture systems.
All in all, it is exciting to see such innovative solutions emerging to combat global issues and improve urban efficiency. Although there is still a lot of progress left to be made, ingenious entrepreneurs have shown that farming can be brought to new heights.

Tenders Awarded To Turn 9 HDB Carpark Rooftops Into Urban Farming Sites
With these farming systems, the sites have the potential to collectively produce around 1,600 tonnes of vegetables annually"
September 30, 2020
SINGAPORE - Parked cars will soon make way for growing vegetables as tenders were awarded for urban farming at nine carpark rooftops by the Singapore Food Agency (SFA) on Wednesday (Sept 30).
The sites, which are rooftops of Housing Board multi-storey carparks, comprise five single sites and two clusters of two sites each. They were awarded to six tenderers.
Each site has a term of up to three years.
The highest tender of $90,000 for annual rent was awarded to IT Meng Landscape and Construction for a cluster site in Jurong West, with one site spanning a total area of 3,311 sq m - three-fifths of a football field - and the other at 2,974 sq m.
Other carpark locations include Choa Chu Kang, Tampines, Hougang, Ang Mo Kio, Toa Payoh, and Sembawang.
SFA chief executive Lim Kok Thai said: "The successful tenderers' proposals included hydroponic and vertical farming systems with a variety of innovative features such as IoT (Internet of Things), blockchain technology and automated climate control."
With these farming systems, the sites have the potential to collectively produce around 1,600 tonnes of vegetables annually."
He added: "We look forward to seeing these HDB multi-storey carpark rooftops transform into productive vegetable farms that will contribute to Singapore's '30 by 30' goal, and we will render assistance and guidance to farms where needed."
The 30 by 30 goal refers to Singapore's aim to produce 30 percent of the country's nutritional needs locally by 2030.
Ms. Phoebe Xie, 30, director and co-founder of local urban technology company AbyFarm, was one of the six who successfully tendered for the carpark rooftop spaces. With the 3,171 sq m site at Ang Mo Kio, the company hopes to begin construction of the farm in the next few months, and to have its launch date within the first half of next year. Using a combination of hydroponics and aeroponics vertical farming methods, the farming process is expected to use 90 percent less water, and it is said to be 10 times more productive compared to traditional methods. “The farm will be entirely automated, with real-time technology used to control the environment within the green house, and to consistently monitor the crops and early identify the possibility of bad crops, which will ensure the quality of our crops,” she said. With an expected yield of 200 tonnes of fruits and vegetables each year, the company is looking to harvest local favourites, such as kang kong and kailan as well as other types of produce such as mushrooms, figs, and Japanese melon. Co-founder of SG Veg Farms Eyleen Goh, 46, who secured a cluster site at Sembawang, said the company is expecting around 80 to 100 tonnes of vegetables per site each year. The company will be selling most of its produce to nearby supermarkets, though it hopes to host weekend markets for residents to buy its vegetables.
Minister for Sustainability and the Environment Grace Fu said in a Facebook post on Wednesday that “the challenges of Covid-19 and climate change, together with other trade and environmental pressures, pose a threat to Singapore’s supply of critical resources such as food”.
As land is scarce in Singapore, the SFA has been “unlocking alternative spaces to grow food, such as vacant buildings, like the former Henderson Secondary School and carpark rooftops”.“
Over the next few years, we will be master-planning the larger Lim Chu Kang area and will be engaging the stakeholders and the public in the process,” she said, adding that there are longer-term plans in place to “expand agriculture in the Lim Chu Kang area and aquaculture off (Singapore’s) southern coast”.
Mr. Melvin Chow, senior director of SFA's food supply resilience division, said in May that the launch of the tender for the nine sites came as a result of growing interest from both the industry and the public towards urban farming in community spaces.
Last year, a pilot urban farm - spanning 1,900 sq m - was launched at a multi-storey HDB carpark in Ang Mo Kio. Known as the Citiponics Farm, it aims to grow up to four tonnes of vegetables a month.
The tender for the nine sites, which was launched on May 12, had closed on June 16, and the sites were awarded using the price-quality tender method, where both the bid price and the quality attributes, such as production output, design, and site layout, as well as business and marketing plans, were factored into the tender evaluation.
The SFA said it will be working with HDB to tender out more multi-storey carpark rooftop sites for urban farming in the fourth quarter of the year, as the move is also in line with HDB's Green Towns Programme to cool HDB towns through the use of greenery, such as on carpark rooftops.
More details of these plans for tender will be released at a later date.

GERMANY: ‘Urban Farming’: Are Rooftop Fields The Future?

This article is part of our special report New terminologies in sustainable food systems.
Large cities offer millions of square meters of unused roof space. Why aren’t they being converted to cultivate crops? The potential seems enormous, but “urban farming” is still in its infancy. EURACTIV Germany reports.
Salad from the roof of the supermarket or tomatoes from the facade of a high-rise building? What sounds like fiction is already a reality in some cities, albeit on a small scale. Urban farming is not a new concept, but one that has hardly been exploited to date.
Cultivating fruits and vegetables could experience a boom in the coming decades. After all, the human population is growing rapidly and is increasingly settling in cities. More than half of this population is already living in cities, and by the middle of the century, around 66% of people are expected to be living in cities – out of a world population of 9.7 billion.
More food also means correspondingly more demand for farmland, but this already accounts for 42% of the global land area.
Another problem is transport. According to the Fraunhofer Institute, around 12% of agricultural emissions are attributable to this alone.
As the World Summit on Biodiversity opens on Wednesday (30 September), new measures to halt its decline are being discussed, including the concept of payments for environmental services, which is currently widely debated in France and Europe. EURACTIV France reports.
Urban gardens for times of crisis
Could urban farming be part of the solution? One thing is certain: The idea is not new. Until the 19th century, cultivating crops was common practice within cities. When they disappeared, private allotment gardens spread.
Interestingly, a new trend is emerging: self-sufficiency is booming in the city, especially in times of crisis.
Often with success, as the British example shows: During World War Two, the government launched the “Dig for Victory” campaign. As a result, up to 50% of fruit and vegetables were produced by the population in allotment gardens.
In Spain, during the economic crisis, the proportion of allotment plots and community gardens increased six-fold between 2006 and 2014.
Apart from private cultivation, however, there are hardly any places where agriculture takes place on a larger scale in cities.
Roof gardens of the future use domestic heat and rainwater
In Europe, urban farming is still in its infancy.
“Every morning, I ask myself why not many more cities invest in it,” says Jörg Finkbeiner, architect, and co-founder of the Berlin network ‘Dachfarm.’ The consortium consists of gardeners, agro scientists, and architects, who together plan greenhouses for growing crops in the city.
However, Finkbeiner believes that this cannot be the case with urban farming, because most buildings are not statically suitable for it: “If you put crops in tubs on a roof and water them, you can quickly achieve 300 kilograms per square meter. Most buildings can’t support that.”
Dachfarm, therefore, relies on roof structures that are as light as possible and are built on top of existing buildings. The plants grow either in substrates such as pumice, lava or compost, as these are much lighter than soil or in hydroponic systems, where the nutrient supply is provided directly via a nutrient solution.
The glass gardens are designed to operate as efficiently as possible by using the waste heat from the building, collecting rainwater, or recycling greywater from households.
The concept of soil carbon sequestration, a cornerstone of regenerative farming, is regaining strength as a key measure in both climate mitigation and adaptation.
With Dachfarm, we want to show that the increasing amount of pavement in cities and the loss of arable land do not contradict themselves, Finkbeiner told EURACTIV.de.
Other advantages are that roof gardens can be used to produce close to the consumer and “on-demand,” so to speak, eliminating long transport routes or the need to store food. But not every type of agricultural cultivation is structurally possible, Finkbeiner points out. Besides, there are many open questions particularly in terms of building codes.
Bologna and Amsterdam with great potential
For supermarkets or restaurants, the own roof garden could be an attractive concept.
However, it is not worthwhile for everyone, because investment costs are still comparatively high and the food harvested in this way is more expensive.
A 2017 study by the European Parliament’s Scientific Service (EPRS) also came to the same conclusion: urban agriculture is “associated with considerable ecological, social and health benefits,” but can increase biodiversity and counteract the heating of cities.
However, this is also associated with high operating costs, for example for electricity, and is in competition with other types of use, for example for solar energy systems. In addition, the report says, tensions between “traditional and innovative farmers” and an increase in land values are also concerns.
There are no reliable figures on how widespread urban farming is in the EU. However, according to the ERPS evaluation, the potential could be huge, depending on the city.
In Bologna, for example, more than three-quarters of the vegetables consumed there could be grown in roof gardens. In Amsterdam, where currently only 0.0018% of food is produced locally, up to 90% of the fruit and vegetables consumed could be grown.
In a clear nod to the strategic importance of agroforestry, the term has now cropped up in both the European Green Deal, the European Commission’s roadmap for making Europe the first climate-neutral continent by 2050, and the EU’s flagship new food policy, the Farm to Fork (F2F) strategy.
Commission has no plans special funding
These figures seem optimistic, as they would probably require strong political support. In the current EU Common Agricultural Policy, urban farming projects can theoretically be financed with funds from both pillars as well as from the European Social Fund and the Regional Development Fund, but this is at the discretion of the member states.
Further support is not in sight, as the Commission “currently has no plans to coordinate strategies for urban agriculture beyond different levels of government,” according to the response EU Agriculture Commissioner Janusz Wojciechowski gave in the European Parliament in May.
However, a planning study on the topic is currently being prepared. This should be completed this autumn.

Today’s Rooftops Are Increasingly Becoming Green Spaces As Part of A Drive Towards Cleaner Cities
Today, there are often financial incentives for going green. In Hamburg, green roofing measures for both residential and commercial buildings are subsidized with up to €50,000 via the Hamburg IFB bank
September 23, 2020
Contributors: Erin Williams & Isabel Scruby
Take a bird’s eye tour of many of the world’s well-known cities and there’s one noticeable feature they have in common: a growing number of green roofs.
Whether it’s carefully cultivated gardens on Chicago’s skyscrapers, urban farms nestled among Hong Kong’s towers, or grassy layers atop many of Copenhagen’s large buildings, more cities have brought in planning laws mandating green roofs on new developments.
Toronto, for example, introduced laws for new buildings or extensions greater than 21,000 square feet back in 2009. Since then, developers have had to cover between 20 and 60 percent of their buildings with vegetation – and while they can opt-out for a fee, fewer than 10 percent choose to do so, according to data from Toronto’s City Hall.
Other cities have opted for more flexibility. In San Francisco, 15 to 30 percent of roof space on new buildings must incorporate solar panels, green roofs, or both.
“Local government policy has and continues to be the major game changer as more cities aim to improve air quality, protect against flooding and heat stress during heatwaves, and build nature back into the urban environment,” explains Isabel Scruby, Planning, Development & Heritage consultant at JLL.
It’s a far cry from when green roofs first appeared 50 years ago when it was often charities or housing cooperatives leading the charge in German cities such as Düsseldorf and Stuttgart, today considered Europe’s green roof capital.
Driving a greener future
Today, there are often financial incentives for going green. In Hamburg, green roofing measures for both residential and commercial buildings are subsidized with up to €50,000 via the Hamburg IFB bank.
In America, Washington DC’s stormwater regulations and Philadelphia’s tax credit scheme both encourage green roofs.
In London, there are no such incentives. However, it’s now home to some 42 percent of the UK’s overall green roof space, in part through residential schemes such as Barnet’s Collingdale Gardens and Islington Square.
“Since 2008, there has been a clear drive in the uptake of urban greenery in London – specifically living walls and green roofs – as part of the Living Roofs and Walls Policy,” says Scruby.
The challenge is for those areas where there are low levels of greenery to improve, says Erin Williams, consultant in JLL’s Upstream Sustainability Services team.
“That will require more developers and existing real estate owners to embrace to the idea.”
While there are certainly practical issues to overcome, from transporting materials onto the roofs to ongoing irrigation and stormwater management, there are also benefits for investors and tenants.
“Developers or redevelopers sometimes need convincing of the benefits of a green roof on a property’s long-term value and energy efficiency,” says Williams.
While utility costs vary between cities, the National Research Council of Canada estimates a green roof can reduce air-conditioning use by up to 75 percent.
And comparing the expected cost of a conventional roof with the cost of a 21,000 square-foot green roof, a 2006 study from the University of Michigan found that over its lifetime, a green roof would save about $200,000, with almost two-thirds of that in energy.
Appealing to modern tenants
While green rooftop space can be left vacant or landscaped for recreational use to help improve health and wellbeing among building tenants, some rooftops are going down a different route.
With greater public concern over climate change and a growing appetite for locally sourced produce, urban farming is starting to take off – with rooftops often offering high-quality environments to grow fresh produce. The world’s largest urban farm, Agripolis’ Nature Urbaine, recently opened on a central Paris rooftop.
In Exeter, the Crown Estate’s Princesshay rooftop garden, which includes five hives, fruit trees, and a herb garden, is home to around 100,000 bees. Since launching in 2012, honey is sold in a delicatessen below.
“Using green roofs to grow fruit and vegetables is a great opportunity to move rooftops away from purely recreational use and drive more value from them while also benefiting the local community and wildlife,” Williams says.
It’s a model that property owner YKK has implemented in Hong Kong to create a 9,000 square foot urban farm producing organic vegetables that are donated to local charities to help feed people in need.
“We’ve turned the building’s under-utilized space into a vibrant place where our tenants volunteer to help cultivate the plants,” says Sotomi Funasugi, director and factory manager at YKK (HK) Limited. “It not only allows tenants to relax and socialize, but it also strengthens bonds with the community by supporting local charities and helping schoolchildren to learn about growing vegetables.”
While the number of green rooftops – and their range of uses – continues to grow, Williams says there’s room for the concept to grow further, pointing to Paris’ plans to make its rooftops a key part of its green transformation.
“As planning policy filters through and has a greater impact on developer thinking, there’s a strong possibility adding a green roof simply becomes part of planning applications,” Scruby says. “That’s the hope. We’re not there yet - but progress has been made.
A Thai University Leads The Way In Organic Urban Agriculture
The 7,000sqm rooftop garden at Thammasat University is the largest such green space in Asia
September 14, 2020
It was on a sunny afternoon recently that teachers and students from Thammasat University in Bangkok, Thailand, set about harvesting organically grown rice.
They gathered on a rooftop urban farm in a bustling metropolis where skyscrapers dominate the landscape. As in many busy capitals, Bangkok is covered in unhealthy exhaust fumes and green spaces are scarce, apart from small city parks.
That is why the rooftop farm project Thammasat University, one of the country’s leading institutions, can point the way forward in greening this sprawling city, which was known in times past as the Venice of Asia thanks to its numerous canals that then still crisscrossed the landscape.
The 7,000sqm rooftop garden at Thammasat University is the largest such green space in Asia. Its design mimics scenic rice terraces on northern Thai hillsides so that rainwater used for growing crops can be absorbed and stored, which means that the farm can function with maximum water efficiency.
“We tend to make a distinction between buildings and green spaces but green spaces can be part of building designs in cities like Bangkok, which has few green spaces,” said Kotchakorn Voraakhom, chief executive and founder of Landprocess, an urban design firm.
The Thai university’s rooftop garden serves several purposes, one of which is the cultivation of chemicals-free crops, including organic rice. The project seeks to help wean Thai farmers off pesticides and insecticides in a country where such chemicals remain widely in use in agriculture.
The intensive use of chemicals at farms across Thailand is posing serious environmental concerns. From 2009 to 2018, Thailand imported vast quantities of agricultural chemicals, such as herbicides, insecticides and fungicides each year. In 2018 alone, more than 156,000 tons of such chemicals were brought into the country.
That same year more than 6,000 locals fell severely ill from exposure to hazardous chemicals and nearly 3,000 people were sickened from exposure to insecticides, according to health officials.
A goal of the sprawling rooftop farm at Thammasat University is to popularize chemicals-free produce like vegetables. And it is not only students and university staff who can grow organic crops: anyone who wishes to grow organic crops is welcome to join. People are invited to grow crops for themselves or else sell them to the university’s kitchens.
Towards the aim of setting up a chemical-free food system, the university is planning to set up an organic canteen and an organic market in the area.
Urban Farming: Four Reasons It Should Flourish Post-Pandemic
Since lockdown, public interest in growing fruit and vegetables at home has soared. Seed packets are flying off shelves and allotment waiting lists are swelling, with one council receiving a 300% increase in applications
Since lockdown, public interest in growing fruit and vegetables at home has soared. Seed packets are flying off shelves and allotment waiting lists are swelling, with one council receiving a 300% increase in applications. Fear of food shortages will have motivated some, but others with more time on their hands at home will have been tempted by the chance to relieve stress doing a wholesome family activity.
The seeds of enthusiasm for home-grown food may have been sown, but sustaining this is essential. Urban farming has much to offer in the wake of the pandemic. It could help communities boost the resilience of their fresh fruit and vegetable supplies, improve the health of residents and help them lead more sustainable lifestyles.
Here are four reasons why food growing should become a perennial feature in our gardens, towns and cities after COVID-19.
1. Growing greener towns and cities
More than half of the global population lives in urban areas, and this is expected to rise to 68% by 2050. For the UK, this is even higher – nine out of 10 people are expected to live in towns and cities by this time.
Weaving food growing into the fabric of urban life could bring greenery and wildlife closer to home. The COVID-19 lockdown helped reawaken interest in growing at home, but one in eight UK households have no access to a garden. Thankfully, the opportunities for urban farming extend beyond these: rooftops, walls – and even underground spaces, such as abandoned tunnels or air raid shelters, offer a range of options for expanding food production in cities while creatively redeveloping the urban environment.
Edible rooftops, walls, and verges can also help reduce flood risk, provide natural cooling for buildings and streets, and help reduce air pollution.

2. Resilient food supplies
Diversifying where and how we grow our food helps spread the risk of disruption to food supplies.
The UK’s reliance on imports has been growing in recent decades. Currently, 84% of fruit and 46% of vegetables consumed in the UK are imported. Brexit and COVID-19 could threaten the steady supply, while the problems created by climate change, such as water scarcity, risk disrupting imports of food from abroad.
Growing fruit and vegetables in towns and cities would help resist these shocks. The harvest labour shortages seen during the pandemic might not have been felt as keenly if urban farms were growing food right where people live.
Vertical and underground crops are more resilient to extreme weather or pests, indoor growing environments are easier to control than those in the field, and temperature and humidity is more stable underground. The high start-up costs and energy bills for this type of farming has meant that indoor farms currently produce a small number of high-value crops, such as leafy greens and herbs. But as the technology matures, the diversity of produce grown indoors will expand.

3. Healthier lives
Getting out into nature and gardening can improve your mental health and physical fitness. Our research suggests that getting involved in urban food growing, or just being exposed to it in our daily lives, may also lead to healthier diets.
Urban growers may be driven to make healthier food choices for a whole range of reasons. They have greater access to fresh fruit and vegetables and getting outdoors and into nature can help reduce stress, making people less likely to make unhealthy food choices. Our study suggested that urban food growing can also help change attitudes towards food, so that people place more value in produce that’s sustainable, healthy, and ethically sourced.
4. Healthier ecosystems
While urbanization is regarded as one of the biggest threats to biodiversity, growing food in towns and cities has been shown to boost the abundance and diversity of wildlife, as well as protect their habitats.
A recent study found that community gardens and allotments act as hotspots for pollinating insects, because they tend to contain a diverse range of fruiting and native plants.

If designed and implemented properly, allotments and community gardens can really benefit biodiversity. Not only should barren spaces be converted into green and productive plots, it’s also important that there are connections between these environments to help wildlife move between them.
Canals and cycle paths can act as these wildlife corridors. As we begin to diversify the spaces used to grow food, particularly those on our rooftops and underground, an exciting challenge will be finding novel ways of connecting them for wildlife. Green bridges have been shown to help wildlife cross busy roads – perhaps similar crossings could link rooftop gardens.
All these reasons and more should compel us to scale up food production in towns in cities. COVID-19 has given us cause to reevaluate how important local urban green spaces are to us, and what we want from our high streets, parks, and pavements. Judging by the garden center sales, allotment lists, and social media, many people have decided they want more fruit and veggies in those spaces. The opportunity is there for urban planners and developers to consider what bringing farming to urban landscapes could offer.
