Forget Politics, Danny Ayalon Wants to Effect Change on The Ground

Having transitioned from politics to agriculture, Danny Ayalon shares how vertical farming, which provides fresh fruits and vegetables all year round, and lab-grown meat can rehabilitate the environment and dramatically reduce household expenditures.
The coronavirus pandemic has drawn attention to humankind's carbon footprint. More than ever before we ask ourselves, how can we become more sustainable? Can we prevent pollution? How can we minimize waste? What about lowering emission levels? Will there be enough food for everyone in the future?
Danny Ayalon, a former ambassador and foreign policy adviser to three prime ministers-turned entrepreneur, believes that the answer to many of the world's problems lies in modern agriculture.
Having transitioned from politics to agriculture, he works with Future Crops, an Amsterdam-based company focused on vertical farming – the practice of growing crops in vertically stacked layers that often incorporates controlled-environment agriculture, which aims to optimize plant growth – and MeaTech, a company that creates lab-grown meat.
"Ever since the coronavirus came into our lives, we realized that man is not in charge of the universe," Ayalon told Israel Hayom.
"Our control over the forces of nature, of Earth, of our future is more limited than we had thought. And when we are no longer in charge of the world, only three things guarantee our lives here: food, water, and energy security. Food, water, and energy are three resources that can be depleted and therefore literally cast a cloud on our world.
"Experts have come to a conclusion that one of the most important fields to focus on is agriculture, and indeed we are currently witnessing the most significant agricultural revolution ever since the first agricultural revolution that took place about 10,00 years ago."
Q: Back then, in the first agricultural revolution, there was a need for a lot of land.
"But today we have technology. The name of the game is to reach maximum output with minimum input in the smallest space possible. This is the holy grail of the new revolution. And that is how technology enters the picture. To grow fruits, vegetables and spices today requires lots of space. The technology we developed at Future Crops allows us to minimize the space, increase production and redefine the food supply chain."
Q: How exactly?
"We have a nine-story hangar in Amsterdam to grow crops like coriander, basil, dill, and parsley. It has LED lights, and each plant gets exactly the amount of light it needs. We are the plant psychologists, [we] listen to all its needs and do everything to make sure the plant grows in the most optimal way.
"If it lacks something, it immediately receives water. Everything is done without a human's touch. We use algorithms and big data in collaboration with world-class researchers from the Weizmann Institute. It is essentially the application of vertical farming, growing various crops in vertically stacked layers, in enclosed structures, on soil platforms.
"For example, if it takes a month to grow lettuce in an open field, in a vertical farm, it takes two weeks, half that time. There's also a significant reduction in water consumption, and no pesticides or sprays are used at all. Also, the produce is available in all seasons; it does not depend on the temperature. Whoever likes mangos and strawberries, for example, will be able to enjoy them all year round."
Q: So if produce is grown faster and within a smaller space, is it going to cost less?
"The prices might be a bit higher today because this technology and the various infrastructures require an economic return of the initial investment in them. With time, the process will become more efficient, and the investments will be repaid, so in the end, the prices that the consumer will need to pay will be lower than today.
"Let me give you a simple example. Do you know how much a kilogram [2.2 pounds] of basil costs in Europe today? €90 ($108). In Israel, the price is €20 ($24). In the [United Arab] Emirates, where almost everything connected to food is imported – the prices go accordingly as well. Once you have more innovative vertical farms, consumers will pay much less."
Q: Should we expect vertical farm skyscrapers to pop up all over?
"I'm not sure that we will need skyscrapers, as with time the facilities will become smaller. Imagine that in every supermarket there will be a vertical produce stand with all the vegetables and spices, and later also fruits which you pick on the spot, without the need to move the produce from place to place. That is why vertical farming is also called urban farming, meaning there is no need for fields; you can grow [produce] on the rooftop. No resource limits you."
Q: What about the taste?
"Ours is a fresher and tastier product. I ought to give credit to the Weizmann Institute here. The challenge for them wasn't the quality of the vitamins but the taste, and they managed to achieve a great taste. In the Netherlands, Future Crops already sells parsley, and it tastes outstanding."
Q: Regular parsley lasts for about two weeks in the fridge. What about Future Crops parsley?
"Our parsley has a two-month shelf life, and it does not oxidize within a week or two."
Q: If every country will be self-reliant in terms of agriculture, do you think it will affect relations between countries?
"Economies will become self-sufficient eventually, which will ensure security with far fewer conflicts. There is less and less water in the Middle East, which might someday lead to tensions. We hope technology will reduce the tensions between countries, and territory will be less critical. Our world faces crucial challenges. Food and water security have the potential to either divide or bring us together and ensure our long-term existence.
"By the way, in every developed Western country, like the United States, Australia, and also in Europe, issues of food security, climate, and greenhouse emissions are on the top of the political agenda. We are not talking about it [in Israel,] as security and foreign affairs take the central stage, but Israel does have a lot to offer here."
Q: Do we have the potential to become the Silicon Valley of advanced agriculture?
"Israel takes tremendous pride in its actions that help save the world. Will we become the Silicon Valley of agriculture? There is no doubt about it. We can already see foreign investors who come here to look for opportunities, including my business partner Lior Maimon, co-founder and CEO of Silver Road Capital, and Steven Levin, one of the leaders of the US food industry. Silver Road Capital is a holdings and financial advisory firm with a broad portfolio of high-tech companies, as well as agricultural and food technologies, and represents international companies and funds in investments in Israel and the world.
"Future Crops's goal is to raise 35 million shekels on the Israeli stock exchange to invest in enlarging the existing facilities and [set up] other production lines and facilities in Europe and other continents. We cooperate with the Albert Heijn supermarket chain [in the Netherlands] and a leading food chain in France."
Q: Vertical farming is estimated at $3 billion. Google and Amazon have invested hundreds of millions in the field as well. What is their goal?
"A simple answer would be profit. A longer answer is that they [large corporations] understand that food has the highest demand. People cannot live without food and water, and Google and Amazon understand that potential."
Q: US President Joe Biden took office with the largest team of climate experts ever. That ought to give the field momentum.
"Green energy and vertical farming will get a considerable boost. Climate change and green energy are well-rooted in the Democratic Party's ideology.
"It is also possible that large companies entered the agriculture fields precisely because of the Biden administration; they are worried about their future. They are afraid of a certain dismantling, so focusing on secondary fields is part of a security scenario for them."
Q: Biden also wants to address greenhouse emissions, which are the result of the food production industry, mainly meat. Are Amazon and Google's food counterparts - McDonald's and Burger King - looking for meat substitutes?
"Firstly, cultured [lab-grown] meat does not require grazing land, cows do not need to be fed, and so much land can instead be turned into forests that support the environment. This is an optimistic industry that leaves us with a better world.
"As for the meat alternatives market, there are two major companies in the US that produce plant-based protein, Beyond Meat, and Impossible Foods.
"Impossible's burgers are already at Burger King, McDonald's has partnered up with Beyond Meat, and last November, it announced that it would create its own plant-based burger.
"The problem is that pea protein [used in plant-based burgers,] does not have all the amino acids that animal protein contains. Also, they need to add additives to supplement for taste and smell.
"At MeaTech, where I'm a director, we are on our way to producing animal meat, cultured meat, real stakes: we take a cow's own stem cell from which meat can be produced in almost unlimited quantities. We also use 3D digital printing technology. And we also created a thin layer of meat, carpaccio. Needless to say, no cow was harmed in the process."
Q: Why do you use 3D printers?
"Because there is no need for a human being's involvement. It is relevant now during the coronavirus pandemic when the food supply chain is disrupted. With such printers, your production can continue without delays, whenever you want.
Also, it is theoretically possible to provide food for space flights. Astronauts who go out into space will not have to take food with them; rather, they will be able to produce it on the spot.
"People understand that crises like the coronavirus can disrupt the supply chain and are looking for alternatives. A 3D printer allows restaurants, supermarkets, and butcher shops to have meat without relying on the supply chain."
Q: The death rate from obesity is higher than the death rate from hunger. How will cultured meat affect these statistics?
"It is possible to create meat with much less fat and more protein in each portion and add various nutrients in the future to strengthen the immune system and prevent disease. This, of course, requires a lot of research and approvals. Just like there's talk about customized medicine, so it will be possible to produce food that suits a person's genetic structure and body in the most optimal way."
Q: Will the cost of this meat also be optimal?
"They will cost more in the beginning compared to regular meat because there are initial costs that have to be repaid. When it becomes a mass production, prices will drop over time."
Q: With your vast experience in politics, what do you think of Israeli politics these days? Do you ever consider a political comeback?
"No election campaign goes by without someone making me an offer [to return to politics] but I'm not interested. Unfortunately, the Israeli government, and all governments in the Western world, have not been able to run their countries properly in recent years.
"For example, more of the government's national taks are transitioning to the private market or the third sector. We see that associations [are the ones] who take care of the needy, establish settlements in the Negev and in the Galilee, bring immigrants to Israel and provide Israelis with information. All these things should be done by the government.
"The Israeli government lacks vision, ideologies, every matter is personal and is charged with negative sentiments. If I do return one day, it will only happen after we change the government system which will take its power from small [political] parties.
"In my opinion, we need to transition to a regional choice, by district. This will result in higher quality politicians. How so? Because whoever wants to be elected will need to run and convince the people who live in his area and district, and they are the ones who know his activities best. Also, closed primaries should be avoided because they make all kinds of deals possible. That needs to change."
Is AppHarvest the Future of Farming?
In this video from Motley Fool Live, recorded on Jan. 28, Industry Focus host Nick Sciple and Motley Fool contributor Lou Whiteman discuss AppHarvest, one such SPAC that is looking to disrupt the agriculture industry. Here are the details on what AppHarvest wants to do, and a look at whether the company represents the future of farming.
Special purpose acquisition companies, or SPACs, are red-hot right now, with investors clamoring to get into promising young companies.
In this video from Motley Fool Live, recorded on Jan. 28, Industry Focus host Nick Sciple and Motley Fool contributor Lou Whiteman discuss AppHarvest, one such SPAC that is looking to disrupt the agriculture industry. Here are the details on what AppHarvest wants to do, and a look at whether the company represents the future of farming.
Nick Sciple: One last company I wanted to talk about, Lou, and this is one I think it's -- you pay attention to, but not one I'm super excited to run in and buy. It was a company called AppHarvest. It's coming public via a [SPAC] this year. This vertical farming space. We talked about Gladstone Land buying traditional farmland. AppHarvest is taking a very different approach, trying to lean into some of the ESG-type movements.
Lou Whiteman: Yeah. Let's look at this. It probably wouldn't surprise you that the U.S. is the biggest global farm exporter as we said, but it might surprise you that the Netherlands, the tiny little country, is No. 2. The way they do that is tech: Greenhouse farm structure. AppHarvest has taken that model and brought it to the U.S. They have, I believe, three farms in Appalachia. The pitches can produce 30x the yields using 90% less water. Right now, it's mostly tomatoes and it is early-stage. I don't own this stock either. I love this idea. There's some reasons that I'm not buying in right now that we can get into. But this is fascinating to me. We talked about making the world a better place. This is the company that we need to be successful to make the world a better place. The warning on it is that it is a SPAC. So it's not public yet. Right now, I believe N-O-V-S. That deal should close soon. [Editor's note: The deal has since closed.] I'm not the only one excited about it. I tend not to like to buy IPOs and new companies anyway. I think the caution around buying into the excitement applies here. There is a Martha Stewart video on their website talking up the company, which I love Martha Stewart, but that's a hype level that makes me want to just watch and see what they produce. This is just three little farms in Appalachia right now and a great idea. This was all over my watchlist. I would imagine I would love to hold it at some point, but just be careful because this is, as we saw SPACs last year in other areas, people are very excited about this.
Sciple: Yeah. I think, like we've said, for a lot of these companies, the prospects are great. I think when you look at the reduced water usage, better, environmentally friendly, all those sorts of things. I like that they are in Appalachia. As someone who is from the South, I like it when more rural areas get some people actually investing money there. But again, there's a lot of execution between now and really getting to a place where this is the future of farming and they're going to reach scale and all those sorts of things. But this is a company I'm definitely going to have my radar on and pay attention to as they continue to report earnings. Because you can tell yourself a story about how this type of vertical farming, indoor farming disrupts this traditional model, can be more efficient, cleaner, etc. Something to continue paying attention to as we have more information, because this company, like you said, Lou, isn't all the way public yet. We still got to have this SPAC deal finalized and then we get all our fun SEC filings and quarterly calls and all those sorts of things. Once we have that, I will be very much looking forward to seeing what the company has to say.
Whiteman: Right. Just to finish up along too, the interesting thing here is that it is a proven concept because it has worked elsewhere. The downside of that is that it needed to work there. Netherlands just doesn't have -- and this is an expensive proposition to get started, to get going. There's potential there, but in a country blessed with almost seemingly unlimited farmland for now, for long term it makes sense. But in the short term, it could be a hard thing to really get up and running. I think you're right, just one to watch.
New Partnership Transports Walmart Into The Future
What’s unique about Cruise is they’re the only self-driving car company to operate an entire fleet of all-electric vehicles powered with 100 percent renewable energy, which supports our road to zero emissions by 2040."
November 10, 2020
This year, retailers had their feet on the accelerator expanding pickup and delivery services so customers can get items they need quickly and safely. In April, Walmart launched Express Delivery and have since scaled it to more than 2,800 stores, reaching more than 65 percent of U.S. households.
"We may be growing delivery options today, but we’re still experimenting with new ways we can use technology to serve customers in the future," said Tom Ward, senior vice president of customer product, Walmart U.S. "This time, we’re cruising over to Scottsdale, AZ, to rev up a new pilot with self-driving car company, Cruise. What’s unique about Cruise is they’re the only self-driving car company to operate an entire fleet of all-electric vehicles powered with 100 percent renewable energy, which supports our road to zero emissions by 2040."
As part of the pilot, which begins early next year, customers can place an order from their local store and have it delivered, contact-free, via one of Cruise’s all-electric self-driving cars. Technology that has the potential to not only save customers time and money but also is helpful to the planet is technology the company said it wants to learn more about.
"You’ve seen us test drive with self-driving cars in the past, and we’re continuing to learn a lot about how they can shape the future of retail," said Ward. "We’re excited to add Cruise to our lineup of autonomous vehicle pilots as we continue to chart a whole new roadmap for retail."
New Green Space Trend In City Centers: Vertical Gardens
One of the major environmental problems we face today is air pollution. According to the World Health Organization (WHO) data, 8 million people die each year from air pollution-related causes
BY MEHMET EMIN BIRPINAR
OCT 27, 2020
Throughout history, the world's population has lived in rural areas by and large. In the 1800s, at least 90% of the world's population lived in the countryside, while the urban population constituted less than 10%. With the development of trade, people switched to urban life as cities became centers of trade.
As industrial production became widespread, migration multiplied and people moved to areas with more production, establishing new and large settlements.
Especially with the Third Industrial Revolution, rapid urbanization began and today, 54% of the world's population lives in cities. By 2050, the world's urban population is projected to rise to 66%.
At the heart of mass migration lies the anxiety of a comfortable life with transportation, communication, education, and health being the most obvious reasons for this. This puts pressure on the area where people migrate to, as the resources are limited but the number of people looking to take advantage of them increases every day. While cities offer people the chance to live a more comfortable life at the same time they create local, regional, and universal problems that are difficult to solve.
Population growth and rising income levels are another source of problems. In our country, the population has increased by 50% in the last three decades from 55 million to 83 million. In the same period, developments within the country, where national income per capita increased by about four times, also led to an increase in consumption. This excessive consumption has undoubtedly put pressure on the environment.
Currently, cities consume 75% of natural resources globally and are responsible for 50% of the waste generated while also producing on average 70% of the world's greenhouse gas emissions.
Of course, cities should address needs, such as food, housing, clean air, water, and waste services but additionally should provide green spaces where citizens can go to be healthy, take a break, and refresh.
Silent Killer: Air Pollution
One of the major environmental problems we face today is air pollution. According to the World Health Organization (WHO) data, 8 million people die each year from air pollution-related causes.
Air pollution is an important environmental problem for Turkey, too. While developments designed to reduce pollution such as the spread of natural gas, the advancement of technology, the spread of public transport and alternative means of transport have been implemented and lowered pollution levels to some degree, pollution caused by public transport, in particular, continues to add to the issue.
The main factor affecting air pollution levels is vehicle density. According to the Turkish Statistical Institute (TurkStat) data, the number of vehicles on the streets in 1990 was 4 million, 8 million in 2008, 23 million at the end of 2019 and has reached 25 million currently. As with the population, about 20% of vehicles are in mega-city Istanbul.
A project carried out by Hacettepe University on behalf of Ministry of Environment and Urbanization revealed that about one-third of these vehicles are over 16 years old and equipped with old technology. This makes the application of green walls, which are becoming more and more common in the world, more attractive and necessary in order to prevent air and noise pollution caused by heavy vehicle traffic.
Refreshing green spaces
According to WHO assessments, the green space per person should be 9 square meters (97 square feet) for a healthy life. However excessive densities occur in some regions that can pose a number of difficulties for green space production.
The new garden trend was developed in order to prevent such problems in several developed megacities such as New York, Melbourne, London, and Paris, in order to alleviate the increased air pollution to some extent and to enable people to relax spiritually.
With the concentration of population density in certain regions within the scope of commercial activities, the space problem has become important in the world, and vertical growth has been achieved by developing multi-story buildings for housing. Vertical agriculture (multistory garden applications), which is also a new application in the agricultural sector which is gradually decreasing due to climate change and soil erosion, is becoming increasingly popular today.
Vertical gardens began emerging in the 1970s but now new types of green spaces are being cultivated that can be put to many different applications. Whether it be a rooftop garden, vertical garden, green or living wall, leading cities around the world including New York, Melbourne, London and Paris are incorporating a bit more nature into their concrete landscapes.
These gardens' most important trait is that they do not require additional space and are usually cultivated on unutilized rooftops or external wall surfaces. Even public transport stops, such as train stations, and the tops of the vehicles themselves are being used to increase the green view.
Benefits at hand
These gardening practices, which have been in our lives for the last 50 years, offer environmental benefits such as preventing air and noise pollution and reducing global greenhouse gas emissions, and economic benefits such as energy savings and reducing possible health costs.
Moreover, they act as a kind of filter for important air pollutants released from exhausts. According to research, a 60-square-meter garden wall can filter 40 tons of harmful gasses and 15 kilograms (33 pounds) of heavy metals. They also contribute to the air quality by absorbing harmful volatile organic compounds.
According to a 2012 article in the Environmental Science & Technology magazine published in the U.S., green wall applications on roads in the canyon structure (with buildings or walls on both sides) reduce harmful dust (PM10) by up to 50%. Again, similar results were obtained in studies conducted under an article published in ScienceDirect in 2016, where green wall applications were seen to prevent air pollutants by 24%-61%.
One of the important effects is the prevention of greenhouse gases. The greenery functions as a swallow space for greenhouse gases that lead to global warming. A living wall of only one square meter removes 2.3 kilograms of carbon dioxide gas from the air, while they also give 1.7 kilograms of oxygen to the environment, which is our source of life.
A study conducted at the Royal Melbourne Institute of Technology, the largest university in Australia, also stated that if green walls are constructed correctly they can act as an ecological buffer, preventing both air and noise pollution. The study's results show that green walls can combat up to 63% of carbon emissions, which would contribute to the fight against climate change.
One of the important benefits is the reduction of noise. Vegetation in vertical gardens allows the noise from vehicles to be dispersed in multiple directions, rather than reflected directly in one. It acts as a kind of noise barrier by dampening it within itself. Up to 40% noise reduction can be achieved depending on the selected plant type and planting frequency.
Vertical gardens also absorb the sunlight, stabilizing the temperature in the region and preventing the formation of heat islands in city centers, one of the major problems caused by global climate change. They also absorb the energy in the environment through plant sweat. However, if it is applied to the external wall of a building, it keeps the building cooler in summer and protects it against adverse weather conditions such as winds in winter, thus contributing to energy saving.
According to the report of the ninth National Roof and Facade Conference held in 2018, the studies carried out by the National University of Singapore showed that reducing the temperature of a building by only one degree leads to as much as 5% in energy saving. Likewise, according to the evaluations of the American Society of Landscape Architects (ASLA), which has a history spanning 120 years, green walls contribute to energy efficiency by 23% like green roofs and rooftop gardens and can reduce temperatures by up to 10 degrees.
In addition, they are more aesthetically pleasing in appearance and provide relief for people as well as acting as the natural habitat for species of birds and insects. In this way, they help promote biodiversity, which is one of the major environmental problems facing the world today.
On the other hand, research shows that they also increase productivity in business environments as cleaning the air eliminates complaints such as headaches, eye irritation, and fatigue caused by air pollution – allowing employees to feel more energetic. They also provide relief by reducing stress.
Watching a green space for 3-5 minutes is known to improve blood pressure, heart rhythm, muscle tension and brain activities. According to relevant research, a green working office increases productivity by 15%. Amazon Towers in Seattle hosts 40,000 plants of 400 different species while the Desjardins building in Canada’s Quebec province is home to the world's largest living wall with a height of 65 meters, housing 11,000 plants.
The 800-square-meter entrance surface of the iconic Musee du quai Branly – Jacques Chirac in Paris has been adorned with 15,000 plants. Paris has a target of covering 1 million square meters of roadside wall, roofs, and façades of buildings facing main streets with greenery.
As part of the Bosco Verticale (Vertical Forest) project, 800 trees and 15,000 plants were planted on the balconies and rooftops of two 111-meter-high buildings in downtown Milan, overwhelmed by air pollution, bringing both fresh air and making it a beautiful site. Additionally, as part of the project, thousands of bird and insect habitats have been created in the center of the city, which has been landlocked by concrete.
A living wall was created in the passenger boarding hall at London’s Heathrow Airport, Europe's busiest airport, to create a healthy environment for passengers. In the section called Garden Gate, seven panels with an area of 4.5 square meters were created, each containing 240 plants.
The motivation to create the gate was customer satisfaction. Passengers reported 47% satisfaction prior to the living wall which increased to 72% once the wall was up and operating healthily.
Likewise, studies carried out by the U.K.'s Birmingham and Lancaster Universities in 2012 revealed that adding more green life to the streets could prevent air pollution by 30% on a cumulative basis. According to British experts, green walls reduce NO2 emissions by 40% and particulate matters by 60%.
In this respect, walls on both sides of a busy main road that runs through London have been converted into green walls. It is reported that a four-meter square wall can produce the same effect as 275 trees. It is predicted that a portion of the £500 million budget allocated for the development of the green infrastructure of the city will be designated for the development of living walls in areas with heavy traffic.
Mexico City, the capital of Mexico, launched the initiative in 2018, covering columns on the roads with heavy traffic and the walls around the roads with green vegetation. The aim is to prevent vehicle-induced air pollution while beautifying the city.
More than 1,000 columns were covered with greenery and living material in an area exceeding 54,000 square meters and the project is expected to meet the oxygen needs of 25,000 people while absorbing 27,000 tons of harmful gases and about 6,000 tons of dust annually.
Turkey's efforts
Great efforts are being made both on a local and national front to increase green areas per capita in our country. As part of its vision project for 2023, the Ministry of Environment and Urban Planning aims to bring 81 million square meters of green space to 81 provinces with the project of national gardens greatly contributing to this goal.
According to the municipal data, as a result of the investments made by the capital Ankara in the last 25 years, the green area per person has reached 20 square meters, marking a 10-fold increase with this figure standing at 6-7 square meters per person in Istanbul and 4-5 square meters in Izmir, another important big city of Turkey. Keeping this value in mind, when we look at other world metropolises, it is around 3 square meters in Tokyo, 5 in Barcelona, 10 in Paris, and 23 in New York.
These values are not the same for the entire province and differ in parts. According to international assessments, woodlands, green vegetation on roadsides, and green spaces on private property (including the gardens of public buildings) are not included in these values.
Therefore, due to space limitations, vertical and rooftop gardens are becoming a matter of greater importance with Turkey creating the necessary regulations in 2013, bringing the issue to legal ground.
The amendment to the Planned Areas Type Zoning Regulation paved the way for the building gardens on rooftops. Given the numerous benefits of green spaces such as air quality, energy saving, temperature balance, and contribution to biodiversity, this regulation is of great importance.
However, we cannot say that rooftop gardens and vertical gardens have become very common in our country.
Municipalities are implementing green initiatives especially in megacities such as Ankara, Izmir, and Istanbul where local governments are cultivating roadside wall gardens in areas with heavy traffic.
Caring for a wall or rooftop garden is very simple as they require minimal interference as they are designed with an internal irrigation system but do need an annual pruning, some fertilizer, or, when called for, the removal of harmful pests. The walls offer numerous ecological, economic, and mental benefits, with municipalities decorating the panels with figures derived from recycled plastic - both reducing maintenance costs and decorating the area.
Istanbul municipality's move
Istanbul Metropolitan Municipality (IBB) administration is taking an odd position after it previously stopped investments in advanced biological treatment plants with a membrane system that would bring with it a new era in wastewater management in Istanbul, saving a lot of money. The 55,000-square-meter green wall application, which offers countless benefits, unfortunately, faces a massacre.
Developing and growing vegetation is being removed and replaced by graffiti using a synthetic chemical paint. The IBB claims the move is due to the walls' high cost as well as pollution caused by the chemicals used in the care of these areas. However, the plants used for the vertical gardens are no different from those in other public parks and gardens and are subject to the same care and chemicals.
People continue to visit public parks, even bringing their children, and do not experience any side effects from the pollutant chemicals used on the plants, so why should the case for the roadside be any different? Moreover, plants in public parks and gardens are prone to vandalism whereas vertical gardens on roadsides are not.
The graffiti process in these areas has negative environmental effects with an average of 11,000 to 15,000 liters of paint being used, meaning at least 5-10 tons of volatile organic compounds will be released into the air. In addition to destroying the benefits of green vegetation, volatile organic compounds are formed as a result of the painting that emits compounds into the air, which are extremely harmful to health. When these compounds interact with NO2 gas released from vehicles it causes the formation of ground-level ozone, which is extremely harmful. Ground-level ozone, whose effects will gradually increase with hot weather, puts those with respiratory conditions such as asthma at great risk.
Colorful graffiti is more likely to distract drivers with dark colors absorbing more solar energy than concrete would, causing temperatures to further rise. The murals decompose faster due to sunlight and other meteorological factors and therefore will inevitably need to be renewed – an inevitable financial burden that eliminates the benefits the vertical gardens offered.
The destruction of a beneficial, functioning system – instead of utilizing the one million square meters of available wall in Istanbul – highlights the lack of planning that has gone into the move.
In our world where the effects of global warming are increasing day by day as heat islands emerge and high air pollution makes city centers more uninhabitable the importance of greenery per square meter increases. Environmental investments should increase rather than eliminating the existing ones.
As we have always said, the environment is an issue that cannot be politicized. Since all environmental investments will prevent health costs, we consider a healthy environment a form of preventive medicine. In this respect, we call on the authorities to do their duty. Let us not destroy the refreshing living walls but rather increase their number as it will benefit us all.

Eighty miles southwest of Beijing, the Chinese government is planning a new five-million person city as a model of sustainability—powered by clean energy, featuring huge green spaces, and unsullied by many cars. A new design shows what neighborhoods in the city, called Xiong’an New Area, might look like.
City blocks would surround courtyards with native plants and garden plots. Apartments, designed for people of all income levels and ages, have large balconies with built-in boxes for gardening; greenhouses with vertical farms sit on the roofs, next to rooftop homes with gardens of their own. The wooden buildings, designed to use 80% less energy than typical buildings, use on-site solar power. Most streets are designed to prioritize people on bikes and on foot, not cars.
