“I’m Opting For Localized Franchised Farming”

“In the States, the food system is so inefficient both in the way it’s produced, at a massive scale and in terms of quality,” says Natalie Radu. "The problem is that consumers are left in the dark. They don’t know what pesticide is used on the food they’re eating. GM foods are not labeled. Let aside the waste this industry has.” Natalie says that many don’t have access to healthy food. When walking around in the Bronx for instance, on the lookout for a grocery store, it’s so much easier to buy a pack of soda for half the price of fresh produce. 

‘Localized franchised farming’
“McDonald's is known for real estate. If only we could do a Wholefoods / McDonalds franchise where customers could walk in and snip off lettuce, directly available to consumers. I’m opting for localized franchised farming. I have been trying to figure out a location in terms of real estate, but, from the perspective of a small business, New Jersey and New York prices are very high. I would have to start out in a place that’s cheaper on average. However, I would definitely apply for grants to fund the initial infrastructure for the farms." 

Natalie Radu in action on her channel

Natalie has her passion for writing and her engineering study to her advantage when starting a farm. “I think because of this intersection I will be able to work with the science and also have the ability to convey that science. I can make the lettuce we’ll be growing feel personal for someone that’s in their own house, miles away or even across the world. That’s the biggest thing, you have to get people excited about vertical farming, at least as excited as you are. However, when it comes down to engineering I’m going to need some help.”

“My family immigrated from Moldova to the US around the collapse of the Soviet Union,” says Natalie. “My grandparents used to grow several fruits in the backyards and my affection for farming started right about there, it’s in my blood.” Natalie, an 18-year-old engineering student has been determined to run her own farm in the future. It all started with finding a proper research topic, which turned into her biggest passion nowadays. 

As Natalie’s based in New Jersey, she is surrounded by several vertical farms. She wanted to pass by some farms near her to visit and stumbled upon Good Feeling Farms. Eventually, Natalie was able to do an internship at Good Feeling Farms to get a better understanding of every aspect of a vertical farm, from seeding to growing to harvesting. Good Feeling Farms is a New Jersey-based wholesale micro greenery that specializes in microgreens and hydro lettuce. The farm is run by a team of three, taking care of the cultivation and harvesting process. 

Inside Good Feeling Farms' growing facility

Ever since her internship, Natalie is determined to run her own farm in the future. She currently runs a YouTube channel, where she experiments with indoor hydroponics. She recently spoke at a local TEDx event about the inefficacies in traditional food production and distribution systems. 

Natalie says: “I’ve tried many growing conditions for plants and I think you can grow them under many different conditions. You have to work with your circumstances. Ideally, your indoor garden would be sustainable. The growth mediums could be sanitized and reused to lessen waste. Besides being water-efficient, vertical farming really shines in the areas of automation and data science. The ability to collect and analyze plant data constantly and instantly modify environmental factors has massive potential for produce cultivation as we know it.”

KEY POINTS

• Henner Schwarz, CEO of German firm &ever, said that his company’s new indoor vertical farm in Singapore will produce 1.5 tons of “leafy green” produce per day.

• Schwarz said he expects produce from his firm’s new research and development facility in Changi will reach a lot of Singaporeans over time and “make a small contribution to food security in Singapore.”

• &ever already has an operational indoor farm in Kuwait, which has become a testing ground for indoor vertical farming.



The boss of German firm &ever has said that his company’s new indoor vertical farm in Singapore will produce 1.5 tons of “leafy green” produce every day when it is up and running in the fourth quarter of next year.

Henner Schwarz, Chief Executive Officer at &ever, told CNBC on Monday that he expects produce from his firm’s new research and development facility in Changi will reach a lot of Singaporeans over time and “make a small contribution to food security in Singapore.”

The company, which competes with more conventional food producers, sells living plants to customers that can then be harvested at home as and when they’re needed. As a result, it tastes better and fresher, Schwarz said.

Schwarz said Singapore is “not the easiest market for indoor vertical farming” as electricity is fairly expensive and there are “lots of cheap imports.”

However, &ever has been awarded a grant by the Singapore government, which decided to speed up plans to increase locally produced food after seeing how the coronavirus pandemic impacted food supplies.

Singapore’s land scarcity makes conventional farming a real challenge and the country is keen to embrace solutions that don’t have a large footprint.

In terms of price, Schwarz said: “We think that we’re pricing our products similar to existing premium organic produce that you can find on the Singapore market today.”

He added: “The price point for indoor vertical farming products in many markets in the world, for example in the U.S., is very expensive. Our system is really geared towards making a meaningful contribution and we have taken quite some time to get things right, and to have the most energy efficient solution on the market.”

In order to reduce energy consumption at its Singapore site, &ever plans to use a combination of sunlight capture systems and LED lights. It is teaming up with lighting producer Signify to carry out a number of experiments.

Kuwait farm

&ever already has an operational indoor farm in Kuwait, which has become a testing ground for indoor vertical farming as it has similar, but different food security issues.

“We launched our farm in Kuwait just when Covid really hit in March,” said Schwarz. “It has been quite difficult to ramp production capacity up. However, the reception in the market has really been great thus far, and the Kuwaiti people really like our produce.”

When it comes to farming, access to fresh water is a problem in many areas of the world. “We need 95% less fresh water than traditional farms,” said Schwarz.

He added: “We expect that over time, as our efficiency becomes better and better, the price points can become lower and lower.”

Today German startup Infarm, one of the world’s fastest-growing urban farming networks, has announced an approx. €144 million investment raised in the first close of a Series C funding round expected to reach around €169 million. Led by LGT Lightstone, the first round included participation by investors Hanaco, Bonnier, Haniel, and Latitude and was supported by existing Infarm investors Atomico, TriplePoint Capital, Mons Capital, and Astanor Ventures.

Founded in Berlin in 2013 by Osnat Michaeli and the brothers Erez and Guy Galonska, Infarm is dedicated to creating a future where local super fresh produce is available for everyone. The farms are placed in various locations in the city, like supermarkets, restaurants, and distribution centers, so that vegetables grow and are harvested close to the moment of purchase or consumption.

These controlled, growing environments are connected to a central cloud-based farm-brain which gathers more than 50,000 data points through a plant’s lifetime, allowing the platform to learn, adapt and improve itself constantly so that every plant grows better than the one before. This modular, data-driven, and distributed approach — a combination of big data, IoT, and cloud analytics, in addition to rapid growth at a global scale — sets Infarm apart from any other urban farming solution.

With a mix of equity and debt financing, the scaleup’s fresh capital infusion brings Infarm’s total funding to date to more than €254 million, underscoring consumer and retailer appetite for Infarm’s innovative approach to fresh, sustainable and local food production in the wake of this year’s pandemic. By 2025, Infarm’s farming network is expected to reach more than 5,000,000 square feet to become the largest distributed farming network in the world as it builds towards helping cities become self-sufficient in their food production.

The investment will be used to deepen the regional and local reach of Infarm’s global farming network and complete the development of Infarm’s new generation of vertical cloud-connected farms, capable of generating the crop-equivalent of acres of farmland and amplifying the diversity of produce currently available through vertical farming. An integration of advanced engineering, software and farming technology, these farms will save labor, land, water, energy, and food-miles while contributing to a more sustainable food system.

Erez Galonska, Co-founder and CEO of Infarm said: “The coronavirus pandemic has put a global spotlight on the urgent agricultural and ecological challenges of our time. At Infarm, we believe there’s a better, healthier way to feed our cities: increasing access to fresh, pure, sustainable produce, grown as close as possible to people. As we scale to 5,000,000 sq ft in farming facilities across Europe, North American and Asia by 2025, this investment will help us make a truly global impact through our network, preserving the thousands of acres of land, millions of liters of water, and ultimately change the way people grow, eat and think about food.”

In the past 12 months alone, Infarm has formed new partnerships with the world’s largest retailers, including Albert Heijn (Netherlands), Aldi Süd (Germany), COOP/Irma (Denmark), Empire Company Ltd (Sobeys, Safeway, Thrifty Foods – Canada), Kinokuniya (Japan), Kroger (United States), Marks & Spencer (United Kingdom) and Selfridges (United Kingdom), driving market expansion beyond Germany, France, Luxembourg and Switzerland to the United Kingdom, the United States, Canada, Denmark, the Netherlands, and Japan.

With operations across 10 countries and 30 cities worldwide, Infarm harvests 500,000+ plants monthly and growing while using 99.5% less space than soil-based agriculture, 95% less water, 90% less transport and zero chemical pesticides. Today, 90% of electricity use throughout the Infarm network is from renewable energy and the company has set a target to reach zero emission food production next year.

Dharmash Mistry, Partner of LGT Lightstone said: “We are excited to partner with the Infarm team to accelerate their urban vertical farm vision, ultimately creating a more sustainable food system for a growing population. Fresher, tastier & healthier food using 95% less land & water, no pesticides and 90% less transport. With over $1 billion of customer demand, partnerships with 17 of the top 50 global grocers, Infarm is set to revolutionize the market behind a unique ‘demand led’ modular business model. We look forward to working with Erez, Guy & Osnat to create a better, healthier & tastier future.”

Pasha Romanovski, Co-founding Partner of Hanaco Ventures said: “We are big believers in vertical farming as we see the traditional industry going through (much needed) rapid disruption these days. We were deeply impressed by Infarm’s founders and management, with their ability to move fast and execute. What is extremely appealing about Infarm is their innovative and modular approach, using cutting edge technology that unlocks added value throughout the supply chain, benefiting both the retailers and end-customers. We see a massive demand in the market for sustainable, environment-friendly, and healthy food – and Infarm has just the right team in place to make this happen.”

Preventing Diseases Coming Into Your Fresh Produce

Sankaran:

“The first thing is to understand the controlling factors. How do you make sure of the soil and the water quality health. Our job is the water quality.” Outside of heavy metals, some micro-nutrients are toxic to plants in moderate concentrations or specific conditions.  KETOS looks at water quality as the first aspect in food safety because elements or toxins in water are often filtered and held by soil.

“If people don’t make the investment to understand water quality, once they realize the damage to their produce, it might be too late. One of the most common things, which we haven’t measured yet but actively looking into it, is how we can understand e-coli. We always end up having e-coli outbreaks and product recalls because of e-coli. We need to get ahead of that because there’s millions of dollars of losses and food waste.”

Safety issues

Kris Nightengale, VP Agricultural Sales notes: “If you look at the US data regarding food safety issues and over 80% of the cases had livestock grazing in proximity or higher in the watershed in relation to the produce field. Indoor and vertical agriculture seeks to solve the problem by taking the food out of the open and into a highly controlled enclosed environment.” Some pathogens are known to translocate in plants and become a part of the cell structure. This means that no amount of washing is going to disinfect the produce.

The KETOS shield continuously monitors the pH, ORP, and chlorine, which ensures chlorine can be maintained at the proper level to ensure effective sanitization. Even though indoor production facilities go to great lengths to filter and treat influent and circulating water, pathogens can still be introduced through fertilizer, worker, and pests.

“Healthy plants are not the hosts for pathogens that unhealthy plants are. Because indoor production works on a circulating loop system, nutrient imbalances can move very quickly through a facility. It’s not uncommon for indoor growers to watch a perfectly healthy crop start exhibiting symptoms of changing vigor in a matter of hours. Water tests are generally infrequent and there is a significant lag time from the lab. KETOS is filling in the massive data gap that growers can directly and immediately tie to crop health”, Nightengale affirms.  

Keeping the water nutritious 

One of the biggest issues that the US is dealing with right now, not necessarily how good the water treatment plants are, but how good the piping across the distribution network. Those pipes could have been laid out 100 years ago and could be contaminated with toxins. Knowing the water quality, both at the source and the destination is very important.

“KETOS is deploying systems to help with irrigation as well as help implement a broader distribution network for leak detection, understanding lead contamination in pipes, so that repairs can be conducted proactively vs. an expensive infrastructure replacement”, Sankaran says. “You cannot act upon what you don’t measure.”

“Agriculture has successfully implemented technology across many facets of its operations and its time for water management to be a more important discussion as this is a precious asset that can impact not just the farmers but of all of the consumers at large .”

Nightengale adds: “KETOS is able to address the gaps in the marketplace today for water intelligence in-depth, and the right kind of data can provide you insights for what’s actually occurring at your fingertips.”

Vertical Farming Is Coming To A Store Near You

View fullsize

September 9, 2020

 by Julien Muller, Maxime Cailler

Inadequate consumption of fruits and vegetables is among the top 10 risk factors for our health. Eating fruits and vegetables daily helps prevent major diseases, ensures an adequate intake of most micronutrients and fibers, and can help displace foods high in saturated fats, sugar or salt.

The health benefits of eating more produce can’t be denied, but what about the old adage “fresh is best”? Locally grown fruits and vegetables have distinct advantages. The less time it takes to get to your plate, the better. Once vegetables are picked and harvested, they begin to lose their nutrients. Also, produce that is grown and sold locally has minimal transportation time, which translates to reduced fossil fuel emissions.

It may soon be common for anyone to pluck a farm-fresh tomato from the vine or choose their lettuce while it’s still growing, even if they live in urban areas without gardens. Indoor farms, and even in-store farms, are fulfilling our need for more local vegetables. These semi-autonomous vertical farms offer fresh, healthy food options by bringing food production closer to consumers.

Vertical farms use state-of-the-art technologies, such as specialized LEDs, to help the vegetables grow. Simulation is used to strategically design and optimize indoor farm lighting to create an optimal environment that decreases growing times.

Vertical Farming Lighting Challenges

Engineers designing in-store vertical farms must consider many optical aspects.

First, for a row containing a certain type of plant, it is important to ensure the right illumination value. Different plants need varying amounts of light to grow, and that amount can vary during the growth cycle.

It is also important to ensure illumination homogeneity through a row so all the seeds grow at the same speed. This eases the burdens of plant care during production and allows harvests to be scheduled as needed.

Similarly, when it comes to the light spectrum, plants don’t need all the wavelengths of natural light to grow. Plants respond best to just the red and blue wavelengths, so traditional lamps mimicking sunlight are a waste of energy. Careful optical design can help to optimize LED lighting to target only necessary wavelengths, saving energy in the process.

Lastly, the amount of light absorbed by the plants should be maximized. The less light plants reflect, the faster they grow, which reduces energy consumption.

Vertical Farms Grow with Simulation

LED lights are the most efficient, effective, and customer-friendly way to illuminate plants indoors. They use low energy, produce little heat, and can be color-optimized for growth.

To show how Ansys SPEOS can be used to design grow-light LED array solutions and simulate an indoor farm, we designed a generic light array with 90 LEDs. According to the literature, a diffuse purple spectrum (containing no green light) is optimal for plant growth. Plants reflect much of green visible light and absorb the rest of the spectrum. Consequently, the light array we created has 45 LEDs in the blue spectrum and 45 LEDs in the red spectrum, combining to make purple.

Grow light array for a purple spectrum

Inside our farm, we first designed eight rows of 15 lettuce plants. Each row is illuminated by three of our purple spectrum light arrays.

View fullsize

Vertical farm isometric (left) and side view.

To take the optical properties (light absorption and reflection) of the lettuce into account, we measured some leaf samples using Ansys’ Portable Optical Measurement Device (OMD). The bidirectional reflectance distribution function (BRDF) obtained was applied to all of the lettuce plants in the geometry.

We then used light simulation to measure and visualize illuminance homogeneity, as well as the vegetables’ light absorption. The results obtained for the first design are shown below.

Illuminance sensor (left) and 3D absorption (right)

We could see that the illumination was not homogeneous on the whole row. We then iterated on the LED array’s position, the spectrum of the LED, and the material of the walls of the vertical farm to produce the most efficient solution.

Vertical Farming Simulation Results Are Illuminating

We spaced the luminaires more evenly and gave more space between the LED arrays and lettuce plants. We also changed the materials on the sides and the back from transparent (absorbing) to white (diffusing). The front of the vertical farm was kept transparent so consumers could see the plants as they shopped.

Vertical farm isometric (left) and side view.

Our next simulation showed that the illumination reaching the lettuce plants is more evenly distributed, producing a more uniform light absorption, as shown below.

Illuminance sensor (left) and 3D absorption (right)

However, the lettuce plants in the front and back are a bit less illuminated, so they might not grow as well as the ones in the center. Because the simulation results are so visually striking, it’s easy to determine where the vertical farming design could be improved. One idea for the front lettuce plants would be to apply a partially reflective coating on the inside face of the front glass to reflect more light toward them. The optimized system would then both ensure an optimal harvest yield and optimal energy consumption.

Vertical farming for in-store produce is an idea making its way to the mainstream. Optical simulation helps quantify and visualize the benefits of vertical farms, such as using less energy and water, and growing what is needed in small batches, which wastes less food.

“We Are Developing A Sustainable Technology That Uses 75% Less LED Lighting”

Verde Compacto, a Mexican start-up, producer of container farms and indoor farming growing technologies, has seen significant demand for their growing systems during the pandemic. 

"COVID is driving this market forward because people want to know what is behind their food and their diets. Logistic chains in countries like South Korea and Arab countries are really dependent on imports. They are trying to implement urban technologies to strengthen their supply chains. As we’re focusing on growing systems, we are trying to turn this into reality. We are growing food in a more sustainable way where everyone can benefit from it”, Juan Gabriel Succar, Co-Founder and CCO of Verde Compacto says.

The company has an R&D container farm, Huvster, with several labs and small scale systems. The company sells some of its crops locally to better understand the urban business model, as Verde Compacto is educating the future indoor growers.

Succar continues: “We are providing the knowledge to any grower that wants to have an urban farm and we are helping them throughout the process by constructing a farm to their needs.” The company does not only build container farms, which is their standard model but also provides custom made projects such as warehouses or buildings. Or on a smaller scale like supermarkets and restaurants. “We provide the knowledge to install a farm at any size”.

Decreasing LED use

Verde Compacto is looking to improve the electricity use for its growing solutions. “We are developing a sustainable technology that uses 75% less LED lighting, which is part of a sustainable R&D project. The tests are still running but they have delivered positive results. In the end, our technology used for indoor farms allows us to rotate the lamps. Rather than using four lamps at one spot, Verde Compacto can use one light that is constantly rotating. That's why we can make such a big impact on light usage”, Succar affirms. 

Lack of quality and water

“Every business model and location has different benefits. As we are one of the largest agricultural countries in the world, we can offer excellent fresh produce quality. The sad story is that all the good fruits and vegetables are exported, thus there is a lack of quality products here in Mexico”, Succar says.

Succar says that Verde Compacto’s technology can build a profitable business model to deliver excellent quality and healthy food to the Mexican society. He notes that the central Mexican region sees a big challenge: a large water shortage. “With our solution, companies still see an opportunity to grow food and maintain their quality by using fewer resources”, Succar notes.

Sustainability

“We always try to give the best options possible regarding our client’s budget, business model, and capabilities. Verde Compacto is cooperating with solar panels to give access to clients for installing these solutions. “Renewable energy, in the end, really depends on the client. Our goal is to make vertical farming as sustainable as we can”, Succar states. At the end of October this year the company will install the first urban farm in Salamanca, Mexico which will be run on 100% solar energy.

Price opportunities

 Succar: “In Mexico, we provide our produce at a lower price level than supermarkets. This is done on purpose, to get people to know about vertical farming. Sometimes we are on the same price level.”

Olivier Kappetein, EU representative at Verde Compacto notes: “We have a financial stimulator and we found out that we can bring product prices down. Consumers would pay less compared to supermarket prices as they are unbelievably high. In the United Arab Emirates, locally grown products are unfindable. An iceberg lettuce costs around €7.60 (9 USD) or more. We could get that price down by at least 350% and still make a profit if we were to sell our produce there. We are aiming to sell high-quality food and that’s what they are looking for.”

Pre- and post COVID story

Verde Compacto has a pre- COVID story and a post-COVID story regarding any company expansions. The pre-COVID story was to expand to all Latin American countries, as a priority. They started several alliances and promoted the Verde Compacto technology in Latin America. However, the economy in Latin America was really affected during the pandemic.

“Thus, countries depending on imports saw a great opportunity in our technology for constant production. We didn’t get behind on the expansion actually. Right now, we are working with associations to open different commercial offices in several countries in Latin America. We will be expanding there at the beginning of next year. We are also exploring different options in different parts of the world, expanding globally. One of the regions is Northern Europe because we saw the need for farming technology in those countries. Especially in Luxemburg, where there’s limited fresh produce available.

“The most common problem in vertical farming is the unawareness of the consumer”, Kappetein adds. “They don’t know what it has to offer. It’s still an investment that needs to be made. There is still a greater focus on organic produce as they are aware of the great benefits that come along.”

The Verde Compacto team

Forage

Verde Compacto has been developing its own R&D department, generating knowledge that is also used for new product lines. Succar continues: “We are developing indoor farming systems that are not limited to leafy greens and herbs, but also for forage e.g.. Forage is eaten by grazing cattle mostly. With our hydro system, we can feed cows e.g. with using fewer resources in a more profitable way. The meat and milk industry is impacting the ecosystem significantly. Implementing this technology will help us to make this type of agriculture more sustainable.” The company is also exploring the opportunities of launching indoor strawberries, with the greatest focus on Europe.

Is Hydroponic Farming Actually Sustainable?

View fullsize

September 4, 2020

According to the UN, the world is on the brink of its worst food crisis in 50 years.

The global food industry is searching for a more sustainable and accessible system for producing healthy food, particularly fresh fruit and vegetables. Techniques such as hydroponics and vertical farming may provide the solution by maximizing overall output and minimizing the use of space, soil, and other resources.

But what exactly is hydroponic farming? And is it actually sustainable?

View fullsize

What Is Hydroponic Farming?

There are a variety of different approaches to Hydroponic Farming. But they all involve growing plants and fresh produce minus the soil.

There are several main styles of hydroponic systems. One uses an absorbent wick to transfer nutrients from a water reservoir up to the roots of the crop. While others leave an air-gap, allowing part of the root system to absorb nutrients directly while the remainder is exposed to oxygen in the air.

Plants may also be positioned on a floating raft, or grown through a medium, into which water is regularly pumped. Top feeding also requires regular water circulation, while aeroponics involves leaving the roots completely exposed but frequently filling or misting the space with nutrient-enriched water.

Whatever the precise method used, hydroponics involves regular exposure to both air and nutrient-rich water. According to Vertical Roots, a South Carolina-based Indoor Hydroponic Container Farm, there are five core elements to hydroponic farming. These are freshwater, oxygen, root support, nutrients, and light.

By growing crops in water, vertically, and in climate-controlled greenhouses, Vertical Roots and other similar farms are able to produce nutrient-dense food anywhere in the world, at any time of year, and using fewer resources than traditional methods.

Is Hydroponic Farming Sustainable?

Soil-less farming techniques, in general, are typically more resource-efficient long term than traditional methods. According to the National Parks Service (NPS), hydroponics can use up to 10 percent less water than field crop watering.

By operating a closed-loop system and recycling rainwater, high-tech greenhouse developer AppHarvest uses up to 90 percent less water than traditional methods.

Most hydroponic farms utilize closed-loop systems, like AppHarvest, that contain and preserve water. This control over the water system also allows for delicate adjustments to the environment. PH levels, amount and type of light, and quantity of nutrients can all be modified to enhance the growth of crops.

Emphasizing perennial agriculture—particularly in combination with vertical farming and hydroponics—can further maximize both production and nutritional content per-plant. Many perennials, which can be maintained all year round with no replanting, are extremely nutrient-dense.

Start-up costs for hydroponic systems are typically greater than for traditional farming. But overall, it produces far greater output with fewer resources. It also allows growers to produce food anywhere in the world. Thereby reducing the carbon emissions generated through transportation, and allowing for year-round production in even inhospitable environments or weather conditions.

In general, hydroponic systems can produce a greater yield of fruits and vegetables. This is in part due to the controlled environment, but also because plants can be housed much more densely than possible using traditional methods. This both increases the overall output and reduces the quantity of land required.

What Is Vertical Farming?

Vertical farming involves the growing of vegetables in stacked layers, frequently in a controlled environment.

Vertical farming also requires much less land than traditional methods. Typically, it incorporates controlled-environment systems such as hydroponics to maximize output. The primary goal of vertical farming is to increase the crop yield while reducing the space required, much like hydroponics itself.

Vertical farming firm Infarm recently partnered with supermarket chain Marks & Spencer to grow fresh herbs in select stores. The company is also working with several retailers and chefs across Europe who aim to add small vertical farms to their restaurants and stores.

“Our vertical farms can be installed directly in any urban space,” said Emmanuel Evita, global communications director at Infarm. “Which is where the majority of the global population will live in the next few decades.”

It is particularly useful for growing produce in areas where there is a lack of arable land. In Abu Dhabi, where there are extremely high temperatures and increasing water scarcity, the government is investing $100 million in indoor farming.

Inner-city gardening, in general, also lends itself to vertical farming. While harder to create a controlled environment, guerilla gardening and other community-based projects have also made use of the vertical system. This enables greater access to fresh produce and reduced mileage overall, even with rudimentary systems in place.

Emphasizing perennial vegetables could also maximize nutrients, increase production, and reduce the consumption of resources.

Why Do We Need Alternative Farming Methods?

Studies indicate that the suburbanization of major supermarkets has led to food deserts within cities. This disproportionately impacts low-income people and those who live in urban areas. Traditional malnutrition affects around two billion people worldwide. But the Standard American Diet (SAD) and lack of access to fresh food is also responsible for chronic deficiencies.

Access to fresh fruit and vegetables is likely to become even more restrictive in the recession following the COVID-19 coronavirus pandemic. And even in countries with plenty of food, there will likely be further disruptions in the food supply chain.

In order to provide enough vegetables for the global population to maintain a healthy diet, food production would need to triple. Alternative methods such as vertical farming and hydroponics could provide a resource-efficient and accessible way of revolutionizing the global food industry.

Gotham Greens, a fresh food farming company, specifically choose to build sustainable greenhouses within cities. Local cultivation helps the company deliver products quickly and with minimal energy expenditure. This also allows those who live within urban areas access to fresh, nutrient-dense food, and to agricultural jobs.

AppHarvest is also creating jobs, minimizing its carbon footprint, and increasing its output with its choice of location. By opening a new facility in Morehead, Kentucky, the company is both tackling high local unemployment rates while placing itself less than one day’s drive from 70 percent of the U.S. population. This reduction in travel for delivery has dropped its overall diesel costs by 80 percent.

“It’s time for agriculture in America to change,” said Johnathan Webb, the founder, and CEO of AppHarvest. “The pandemic has demonstrated the need to establish more resilient food systems, and our work is on the forefront of that effort.”

Urban Vertical Farming: The Key To A Sustainable Future

View fullsize

Living in a dense city population can make you wonder, "where does our food come from?" When you live in urban areas like Houston, New York City, or Seattle, it's rare that you notice farms on your drive to work.

The idea that our food is grown hundreds to thousands of miles away can be worrisome. What if something were to happen to those farms? Our resources would cut off and we would have limited access to foods. This is why vertical farming in urban areas is critical to ensure cities can be sustainable food leaders.

What is vertical farming?

Vertical farming is the practice of growing crops/foods in vertically stacked layers. This is usually done indoors and in a controlled environment. This method optimizes plant growth and allows the use of soilless techniques such as hydroponics.

How does vertical farming work?

Vertical farming needs several things to work. We'll cover each one below:

1. Physical Layout - The purpose of farming indoors is to maximize volume. We do this by maximizing the output efficiency per square meter. This is why you will see physical layouts in the form of skyscrapers or vertical tower-like structures.

2. Lighting - To optimize crop growth, a need for artificial and natural lights are essential.

3. Growing Medium - There are several different growing mediums for vertical farming. These methods include hydroponics, aeroponics, and aquaponics. Coco Coir, Rockwool, ,Biostrate, Vericulite, Perlite, SunShine #4 and Black Gold are great mediums used in indoor farming.

4. Sustainability Features - Sustainable features often used with vertical farming feature rainwater tanks, wind turbines, and spaces with low energy costs.

Why is urban vertical farming important?

By 2050, the forecast is that we will have an extra 2 billion people on the planet. Many of these people will live in urban areas. And we have already used a third of arable farmland in the past 40 years.

We need to come up with other sustainable ways to grow food to ensure we can feed everyone. Vertical farming allows us to grow healthy, accessible foods within a few acres of land, close to home.

This is critical for urban areas because they will become more populated over time. Instead of relying on faraway food sources, we need to take matters into our own hands. By establishing urban vertical farming settings, we'll be able to control and grow our own food sources.

Vertical farming also uses 95% less water than traditional farming methods. The use of water needed to grow crops traditionally is wasteful. To be able to handle an influx in population, vertical farming is a sustainable solution.

How does vertical farming benefit us?

There are many reasons why vertical farming is the future of farming. By building vertical farms, there will be an increase in job opportunities. There will be easier access to healthier and attainable foods. With food grown close to home, we will always be aware of where our food comes from.

Because of the controlled environment, there is a higher chance of growth success. We will be able to grow crops year-round and have larger yields. Crops will not be exposed to harsh weather conditions since they'll be grown indoors. Urban vertical farming methods should start being adopted right now.

The Takeaway

To prepare for the upcoming increase in food demand, urban areas need to adopt sustainable policies. People should start growing their food indoors as well as increasing the demand for high-tech farming methods.

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. 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.

Cities Are Turning To Rooftop Farming

View fullsize

by Erin Tallman

August 24, 2020

With green initiatives popping up, the benefits of rooftop farms are becoming worldly-recognized. We spoke with Thomas Schneider, co-founder and director of Rooftop Roots in Washington DC and Michelle Hong of Rooftop Republic, based in Hong Kong, China to know how to create and run a rooftop garden or farm.

Hong Kongers and city-dwellers are increasingly concerned about the food they put on their dinner tables, According to Michelle Hong of Rooftop Republic, people are increasingly demanding food that is safe, healthy and sustainably produced. With green initiatives popping up, the benefits of rooftop farms are becoming worldly-recognized.  One prime advantage is locality— reducing transport mileage equates to lowering emissions, but there’s more to it than a couple of miles here and there.

When bare roofs receive more heat than they emit, they increase emissions and greenhouse gases. Rooftop farms are also helping to cool buildings as they defer this “heat island” effect. The greenery of rooftop farms absorb CO2 and release oxygen, so buildings don’t diffuse as much heat—a good thing since the United Nations confirms our planet is warming much faster than we think.

There’s more still. Rooftop farming can offer low-income families a new source of revenue and better access to quality products—in the US, only 7% of low-income families eat the proper amount of fruits and vegetables, according to a report done by CBS This Morning.

The Rooftop Society

Both the Rooftop Roots and Rooftop Republic were born from the realization that there was untapped potential in the city and that there was a real rupture between people and their food sources, health and community.

Rooftop Republic provides services to help install, maintain, learn and understand how to grow gardens on the top of the buildings. Some of the gardens act as a platform for corporate employee engagement or for students to immerse themselves in the educational experience of growing their own food. Through these actions, they’re taking a step forward to reconnect people to food explains Michelle Hong,

“Only by addressing this disconnection—this broken relationship—will we be able to change people’s mindsets and behavior and help them make more informed decisions about their food.”

Rooftop Roots was also created with the intention of rekindling this disconnect through providing economic, environmental and social justice. Their ambition is to generate jobs, offer a new source for fruits and vegetables, and establish a community for food deserts.

Choosing the Right Location

Although the benefits are shiny on paper, Schneider reminds us that it’s not easy:

“Rooftop gardens are not going to end world hunger, weather conditions and temperature swings that occur high up render farming a lot more difficult than ground farms. Plants tend to prefer the earth.”

One can’t forget that rooftop farms are on roofs, literally vulnerable to strong winds on structures that need to be secure and have fundamental integrity. In the Hong Kong context, the first thing to consider when starting the urban farming revolution is to identify a good location that has easy access to water, explained Hong.

“Most herbs/veggies require a minimum of 4 to 5 hours of direct sunlight. No matter what containers you use, the bigger the better. The more space you give to your plants the easier they will find it to develop their root systems, to find nutrients in the soil, etc.”

Rooftop Republic is embarking on training more urban farmers of the future, and with the growing demand for urban agriculture, the company is optimistic that the potential of urban farming in creating employment/vocational opportunities, can be huge.

Immeasurable Benefits

Rooftop farming doesn’t require that one purchases land for farming. Underutilized spaces such as rooftops, terraces or even ground surfaces can be re-utilized and re-valued. Although difficult at times, the perks of building community and giving others’ access to natural processes at work are priceless, Schneider maintained. When people begin to understand the tough work involved, a stronger sense of respect for food develops. Hong emphasized:

“People who grow their own food are likely to understand the processes of nature on agriculture, and are more likely to accept ‘imperfect’ produce, as well as be more conscious to treat food purchases with care. We are aiming to change the concept that food is something that we only engage with at the supermarket.”

Rooftop farms and gardens are being implemented to provide greenery and produce just as much as they’re learning experimentations. Today there still aren’t enormous amounts of data concerning the success or results of rooftop projects, which is why Rooftop Roots took it into their hands to initiate a pilot project in 2016 in collaboration with the University of the District of Columbia, in order to establish the best methods and plants for maximum production.

With the intent to improve food scarcity and help other urban growers, the project focuses on the testing of 6 varieties of both strawberries and tomatoes, because as Schneider put it,

“Tomatoes are the gateway drug to gardening.”

In other words: tomatoes are the plant one usually starts out with. Tomatoes are also exceptionally nutrient-dense and somewhat temperamental, so they are an interesting fruit to work with.

Although the teams have been working on this for about 2 years, results are still not definitive and the farmers are not in a position to report their findings. Yet, they can say that tomatoes are definitely not easy on rooftops.

AGRICULTURE FARM FARMING

Hydroponics – The Pros And Cons of Growing In Soilless Medium

View fullsize

Posted by: Alejandro Gutierrez

Hydroponics is the practice of growing food with no soil involved. Hydroponic operations may bring food to places where it would be difficult to obtain. It may also assist in the flaws of our current food system.

In 2018, the CDC and the FDA issued two safety alerts for Romaine Lettuce in seven months. Consumers across the United States were urged to avoid Romaine lettuce because of E. coli infection concerns. It took weeks for the FDA to announce that the agency found the source of the contamination. The advisory prompted many food stores, including Whole Foods to remove all Romaine lettuce from their shelves.

Situations like these are scary for consumers. And not surprisingly, they’re also angry. People are frustrated about how little they know about the source of fresh produce they buy at grocery stores. Urban farming ventures are taking advantage of concerns about the safety of fresh food. Food miles also become relevant. Consumers desire to avoid fresh food that may have been grown with unfavorable conditions. In some cases, pesticide drift from near farms also poses a threat.

Hydroponics offers an answer and a solution to all these concerns. And it presents an opportunity for healthy and eco-conscious people to gain control over the source of their fresh food.

Let’s look at the pros and cons of hydroponics. We’ll look at the advantages and disadvantages that apply to urban farming companies catering to local consumers. Followed by those to home gardeners who are involved in hydroponics on a vastly smaller scale.

The Pros and Cons of Hydroponics for Urban Farms

Advantages

• In many cities, urban farms bring business to abandoned buildings and decaying neighborhoods. Their presence benefits the area and encourages the restoration of unused and abandoned buildings.

• Urban farms create jobs in areas with limited or non-existent job opportunities.

• Hydroponic growing offers training opportunities for young people in the community, providing skills they can be used in later life.

• Community growing brings fresh food to “food deserts,” eliminating the excuse that area residents had for not eating healthier foods.

• Growing hydroponically within the city gives people access to locally grown food that doesn’t have to travel so far.

• Food grown on urban farms is picked at the peak of freshness, so it’s higher in nutrition.

• Urban farms lower the carbon footprint of food production. Because they use so water efficiently, hydroponic systems are far eco-friendlier. And the food doesn’t have to travel as far. The use of LED lights increases the energy-efficiency of hydroponic systems.

• Government officials have instant access to information about hydroponic produce and its path from the controlled environment to the consumer.

• Consumers have the assurance that there won’t be any problems with bacterial contamination. They can trust the source of the produce they buy.

• Access to high-quality fresh, locally grown produce means that they don’t have to buy more than they can use. This ensures they’re not wasting food or throwing money away.

• Hydroponics eliminates the need to use chemical pesticides and insecticides

Disadvantages

• Urban agriculture doesn’t solve the problems of gang violence and crime in low-income neighborhoods but it’s a great start.

• Businesses that want to establish urban farms in big cities have to go through lengthy applications. From the business license to the zoning permit, it may be a tedious process.

• An urban agriculture venture isn’t likely to bring lots of jobs to the community in the short run. It is not until it establishes itself that results come in the long-run. 

• It will take time for the company to create the conditions for growing conditions. Assembling a hydroponic system that can handle large scale food production will also require some effort.

• The company will need to consider transportation and parking needs for the employees. There may be concerns regarding parking for workers; having an impact on the parking situation for people who live in the neighborhood. However, a good solution with be biking

• There may be a high cost of installing a backup power system (like generators). This is necessary because the damage of potential power failures would inflict significant losses.

Pros and Cons of Hydroponics for Home Growers

Positive Benefits of Hydroponic Gardening at Home

• Hydroponics brings plants into the home, and the presence of plants improves air quality and overall health.

• Hydroponics encourages people to take an interest in the origin of their food. It also gives them insight on what it takes to bring it to their tables.

• Individuals who have hydroponics systems in their homes have access to better quality, fresher, and more nutritious food.

• When you have a hydroponic system at home, you’re able to pick fresh produce just before using it. There is then less chance that fresh vegetables will sit in your refrigerator because you forget about them.

• Because you can pick fresh food when you need it, you’ll cut the cost of your weekly grocery bills. The money you save from buying fewer groceries can go towards clearing debts or in savings.

• You’ll get a tremendous and invaluable sense of satisfaction from being able to be more self-sufficient.

• Since you’re buying the seeds for your hydroponics system, you can be certain of their origin.

• You can plant and harvest fruits and vegetables grown at your own standard. You are free of paying the premium that is standard for food products that bear the “certified organic” label. This label usually carries the charge to the consumer.

Negatives of Hydroponic Gardening at Home

• The cost of purchasing equipment. Regardless of whether you buy kits like the Tower Garden, or buy the components to build your own. While building a system isn’t cheap, the process is educational and fun.

• Unless you buy a kit that provides instructions, you’ll have a harder time assembling your system and getting it started.

• If you buy a kit, you’ll eventually need to purchase replacement parts, additional accessories, and supplemental nutrients. You should factor these things into the total cost of buying and operating a hydroponics system at home.

• No matter how energy-efficient your system manufacturer claims it is, there will be an extra load on your electrical system. A hydroponic system will increase your utility bill throughout the year. With this issue, eco-friendly alternatives arise, such as solar panels which should be implemented if possible.

• Unless you buy a system that is fully automated, you’ll have to constantly monitor nutrient and water levels. You may also have to turn the lights on or off. Don’t expect to have a productive hydroponic garden unless you’re willing to put the effort in. Checking your plants every day is a must. Observing them will ensure that their growing conditions are acceptable.

• Failing to add water when the reservoir needs it, may burn your motor out, and you may weaken or kill the plants. That would be a significant financial setback.

• A power failure will alter the growing conditions in your hydroponic unit. An extended power failure will deprive your plants of light, water, and oxygen. That’s a recipe for their death.

Hydroponics is no different from traditional gardening in that you get what you put into it. Some of the most significant advantages include being able to grow what you want and when you want to grow it, not being tied to traditional gardening seasons, and not having to do as much maintenance as you would if you tried to grow your food in the ground. A well-maintained hydroponic garden will give you access to healthy and nutritious food at any time. You’ll never have to rush to the grocery store for something because you don’t have it on hand.

Bowery Farming Wants To Make Lettuce Safe, Smart And Tasty

View fullsize

• by Sarah Mahoney  @mahoney_sarah

• August 12, 2020

For decades, consumers have been on a quest for cleaner, safer produce — and agricultural methods that are good for both the palate and the planet.

Bowery Farming, the New York-based indoor farming start-up, thinks it’s mastered the recipe, especially given increasing safety concerns.

Grown indoors, lettuces, greens, and herbs are non-GMO, free from pesticides “and grown with complete transparency,” says Katie Seawell, Chief Marketing Officer. “We are deeply committed to increasing access to high-quality delicious food. We’re going to build an enduring brand — we hope a generational brand — that emotionally connects with consumers.”

Its main selling point? “Our produce tastes better, too, and that means a lot to our core audience.”

At present, the vast majority of produce isn’t branded, “and highly commoditized, not unlike coffee used to be,” she says. “I spent 15 years at Starbucks before joining Bowery a year ago, and I see a lot of similarities. Starbucks is a very mission-driven company, and so is Bowery. We are committed to disrupting the food-supply vision. And through technology, we want people to think differently about how we grow the food we eat.”

Currently, Bowery is selling its products in retail chains such as Walmart, Giant, and Whole Foods Market. It’s also available on Amazon Fresh and believes e-commerce will be one of its biggest sources of growth. “It’s a great cross-section of retailers, and part of our goal-to democratize access to our produce.”

Seawell says it is preparing ads set to break later this year, based on consumer research that uncovered ongoing concerns about widespread lettuce recalls for problems like E. coli and Cyclospora infections.

Mustache is the ad agency, and it also worked with Red Antler for a brand refresh and a new website.

Seawell says the pandemic has also intensified interest in safer, healthier foods. It’s also accelerated awareness of America’s gaping inequalities and inefficiencies in the food system.

So far, Bowery has two farms in Kearny, New Jersey, and the a outside of Baltimore. With its modular technology, it hopes to expand soon. Providing fresh food for underserved communities is also part of its mission, which translates into partnerships with nonprofits, including DC Central Kitchen and Table to Table.

Correction: An earlier version of this story misspelled CMO Paula Seawell’s name, as well as the location of two of its farms. They are in Kearny, New Jersey.

Vertical farms with their soil-free, computer-controlled environments may sound like sci-fi, but there is a growing environmental and economic case for them, according to new research laying out radical ways of putting food on our plates.

The interdisciplinary study combining biology and engineering sets down steps towards accelerating the growth of this branch of precision agriculture, including the use of aeroponics which uses nutrient-enriched aerosols in place of soil.

Carried out by the John Innes Centre, the University of Bristol, and the aeroponic technology provider LettUs Grow, the study identifies future research areas needed to accelerate the sustainable growth of vertical farming using aeroponic systems.

Dr Antony Dodd, a Group Leader at the John Innes Centre and senior author of the study, says: “By bringing fundamental biological insights into the context of the physics of growing plants in an aerosol, we can help the vertical farming business become more productive more quickly while producing healthier food with less environmental impact.”

In Paris, The Pandemic Gave A Boost To Urban Farms

View fullsize

By Catherine Bennett

The largest urban rooftop farm in Europe opened its doors to the public at the beginning of July – two months behind schedule. Stretching the length of two football fields, Nature Urbaine sits on top of a convention centre in the south-west corner of Paris. The farm began growing herbs, fruit, and vegetables just weeks before Covid-19 hit Europe.

Nature Urbaine’s initial plan was to sell produce to restaurants and local businesses in the surrounding area. When France imposed stay-at-home orders, those restaurants and cafés closed overnight. But lettuce and tomatoes don’t stop growing during a global pandemic.

“We had to rethink our entire model, just as we were having our first harvest,” says Sophie Hardy, the farm’s site manager.

The farm began instead to sell directly to consumers. The small team of farmers were the only people allowed on the rooftop during the lockdown, and every morning they would harvest fruit and vegetables grown from seeds sown in March. They sold the resulting food baskets to residents in front of the 15th arrondissement’s town hall the same day.

For Hardy, the pandemic actually helped urban farms to find a new relevance.

“The crisis marked a moment when people living in the city wanted to opt for healthy, quality products found locally,” she explains. “There was a boom in producers selling their produce directly, and a new awareness that local producers were in danger – and, in echo of that, that France’s own position as a leader in the food industry was in danger”.

This fact did not go unnoticed by the French government. President Emmanuel Macron said in a speech on 12 March that delegating the nation’s food supply to other countries was “madness” and called to “take back control”.

As Covid-19 spread across Europe that month, European countries re-erected invisible internal borders, slowing down or even halting entirely cross-border food supply chains. Storage vehicles piled up at borders and seasonal farmworkers, hunkered down in lockdown, couldn’t get to fruit-picking jobs. Some lorry drivers refused to drive across a continent in the grip of a pandemic.

Fearing seeing fruit and vegetables rot in the fields, the government told businesses and consumers to focus on stocking and buying French food products.

In Paris, where residents weren’t allowed to go further than 1km from their homes, some local producers thrived.

Paris’s Socialist mayor Anne Hidalgo has long championed urban agriculture. In 2016, Paris’s city hall unveiled Parisculteurs, a call for ecological and agricultural projects that would receive start-up money. Since then, the platform has funded 38 new urban farms, which produce 800 tonnes of fruit and vegetables every year.

One of Hidalgo’s principle ideas in her recent, successful re-election campaign was the idea of the '15-minute city', a way to rethink urban proximity. The concept aims to turn one of Paris’s drawbacks, its density, into its strength: residents should be able to access every conceivable service within 15 minutes of their homes, from health centres to bars, restaurants, and schools. The city wants to make everything more accessible – including locally grown produce.

La Caverne is one local producer that saw a financial benefit from the lockdown. On the other side of the city from Nature Urbaine and ten metres underground, mushrooms and endives flourish in a former car park that has been transformed into an urban farm.

“For the first time people realised the value of local agriculture,” explains La Caverne’s co-founder Jean-Noël Gertz. “Local producers were able to sell their products at a fair price. They didn’t have a problem finding places that would sell their products, nor did they have to compete with tomatoes from Morocco”.

Although the Covid-19 crisis didn’t entirely rupture traditional supply chains, urban agriculture professionals are hoping that the last few months have proved the importance of a diversified local food supply.

“Urban farms are an essential way of rethinking the cities of tomorrow,” says Anouck Barcat, the president of the French Association of Professional Urban Agriculture (AFAUP). “It’s one of the tools to make a city more resilient. They have so many benefits – we don’t make monofunctional farms”.

There are a number of environmental advantages to urban farms, not least of all their carbon footprint. An urban farm can sell fresh strawberries just metres from where they were grown, rather than having them travel hundreds of miles in a refrigerated container.

Another advantage of urban agriculture is its flexibility: it can slot into the negative spaces of the city, like abandoned railways, empty metro stations and even up the sides of buildings.

“We don’t need to be Haussman,” Barcat jokes, referencing Paris’s most notorious urban planner, who sliced up the city in the 19th century to create its wide avenues and tree-lined boulevards. “We’re not cutting through the city to make way for farms. They can go wherever there’s space: on roofs, in polluted areas, in car parks. We already have the solution for these spaces.”

One criticism levelled at urban farms is that the small yields don’t justify their expense. But both Barcat and Hardy are keen to insist that urban farms should not compete with nor try to replace traditional rural agriculture, but exist in parallel with it.

“We can’t cultivate every type of crop, and anyway, we’re not able to produce enough to feed the entire city. But the crisis has shown that urban agriculture has its place in the city and that this model works,” says Hardy.

France began to ease its lockdown on 11 May. Paris’s restaurants and cafés have reopened, and the city’s open-air street markets are once again selling peaches from Portugal and strawberries from Belgium. The farmers at Nature Urbaine now only have to walk a few metres to deliver their produce to Le Perchoir, the chic cocktail bar and restaurant sharing the same rooftop.

Barcat is philosophical about the slow rise of urban farms, but says that France’s capital has already seen a shift in thinking.

“Of course, some people will go back to their old habits. But others won’t. [The pandemic] has opened up new possibilities. My hope is that the ordinary Parisian will start to introduce more food grown locally in their consumption habits. We’re not going back to zero.”

Welcome To Robbinsville, NJ–Home of The First Municipal Freight Farm!

A One-of-a-Kind Town Farm

View fullsize

Since Freight Farms sold its first farms in 2013, we have had farmers join our community from all over the world, with a range of backgrounds and business models. Yet, the Robbinsville Farm stands out from all of them because it is the first and only Freight Farm owned by a whole town.

That’s right! The Robbinsville Township of New Jersey came together to bring the Leafy Green Machine™ (the fore-bearer of our current Greenery™) to their town, and the farm operations and distribution has remained a town activity ever since. 

We spoke with farm coordinator, Hope Cahill, about her role at the one-of-a-kind Robbinsville farm and how the project gets the entire community–from student to senior citizen–involved.

The town hydroponic farm

A fresh take on a public service.

When the Robbinsville Farm arrived at the local Senior Center in November 2017, Robbinsville became the first municipality in New Jersey (and in the world!) to install a vertical hydroponic Freight Farm. For the town, it was about more than bringing healthy and local food to the community. Robbinsville quickly made their Freight Farm a key piece in education, volunteer, and food access initiatives. The farm’s location on site at the Senior Center was no coincidence either, with a large part of the harvest dedicated to the center’s dining operations and the local chapter of Meals on Wheels.

The initiative was spearheaded by the Robbinsville mayor, Dave Fried, who–upon seeing a similar type of container farm–sent the Robbinsville Recreation Manager a message saying ‘I would love this for the township. Let’s figure out how to do this’. After a long research phase, the town found Freight Farms. For the town, Freight Farms was the perfect choice since they were able to get everything they needed to run the farm–from purchase to supplies, to training, to customer service–in one. To this day, Mayor Dave is one of the farm’s staunchest supporters.

Nearly three years after its installation, the Robbinsville Farm is still serving its community faithfully. The produce goes directly to the seniors at the Robbinsville Senior Center, Meals on Wheels, and the food bank at Mercer Street Friends (a New Jersey non-profit that offers school and employment opportunities and hunger relief programs). In this way, Robbinsville is able to improve food security, increase access to fresh food, and reduce the risk of obesity and obesity-related diseases.

Hope explains the additional value of having a farm directly in Robbinsville

“Because we are distributing so local, we are able to reduce “food miles” that are required to transport nutritious food...Many who volunteer say how relaxing it is therefore we are also improving mental health and promoting relaxation.

Farm Coordinator, Hope Cahill

It takes a village to raise a farm.

With so many important outlets for the produce, one challenge for Robbinsville was to ensure the farm ran smoothly while also engaging as many community members as possible. For that, Robbinsville hired Hope to manage the operations and the large group of volunteers that run the farm. Unlike many of our farmers for whom hydroponics is their first foray into agriculture, Hope came to the Freight Farm a seasoned expert. 

While attending a vocational high school, Hope took courses in Horticulture and Landscape Management which exposed her to a range of plant-related topics, with everything from floral design and landscaping, to pest and greenhouse management. With this experience, she was able to join the Future Farmers of America after graduating; In the years following high school, Hope got certifications from Rutgers University in fields like beekeeping, landscape management, and aquaponics. During that time she served as the New Jersey FFA State Reporter and then State President, which gave her the opportunity to travel the whole state teaching students the importance of agriculture. All this combined experience made her eager to join the Robbinsville Farm team, seeing it as a perfect way to combine her passion for agriculture with her desire to teach and help fight hunger in the local community.

While Hope is the mastermind behind the farm operations, it is the volunteers who really give the farm program life, and capture the whole scope of the Robbinsville community. Volunteers include the seniors who attend the senior center, Meals-on-Wheels recipients, students–and anyone else with the interest and willingness to learn more about hydroponics.

Together, Hope and the volunteers grow a variety of lettuces, such as Butterhead, Bibb, Red and Green Leaf Romaine, Summer Crisp, Oakleaf, Lollo Rossa, and the occasional herbs. The community reaction? They love it.

Hope explains how she manages her large group of volunteers

“Monday and Tuesday are Harvest and transplant days. Wednesday’s, we seed, rotate the towers and do farm maintenance such as cleaning and mixing fertilizers...As Farm coordinator I oversee everything that goes on in the farm and schedule the volunteers. Every Monday I send out the following weeks farm tasks listing jobs to be done and time slots. Then the volunteers will sign up and I will schedule them in.” 

COVID-19 had an obvious impact on the volunteer workforce that drives the Robbinsville farm. When the virus reached New Jersey, only Robbinsville Township paid staff were able to run the farm for the purposes of health and safety. This led Hope and her coworkers to change their operations to best meet the needs of a community in crisis. A simple change, like eliminating a Spring Harvest mix, helped them maximize their weekly harvest and reduce time spent in the small space farm.

In spite of all this, Hope believes that the volunteer program will bounce back after the pandemic thanks to the hard work she and her team have done to get the whole community invested in the farm’s success over the years.

Localization is Seeding Innovative Produce Supply Chains

A Key Theme of These changes is Localization – An Increasing Reliance on Local Growers to Supply Produce To Retail Outlets.

By Chris Mejia Argueta, Alexis H. Bateman, & Ken Cottrill · June 12, 2020

Bateman is a Research Scientist at the MIT Center for Transportation & Logistics and directs MIT Sustainable Supply Chains. Ken Cottrill is the Editorial Director at the MIT Center for Transportation & Logistics.

The COVID-19 crisis is shining a light on the vulnerabilities of food supply chains, as well as opportunities to develop inventive ways to deliver fresh foods such as fruit and vegetables from farm to table.

A key theme of these changes is localization – an increasing reliance on local growers to supply produce to retail outlets. The movement has gained momentum as a result of shifting consumer buying preferences and the need to make food supply chains resilient to a wide array of risks.

What is localization?

From a global perspective, localization can mean reorienting supply chains towards suppliers in specific countries or regions in any market. In this article, we focus on the localization of fruit and vegetable supply chains in the United States.

There are several definitions of what constitutes a “local” food supply in the US. The United States Department of Agriculture maintains that although “local” connotates short geographic distance between producer and consumer, there is no consensus on what products meet the definition. A government definition assumes that a product can be considered locally or regionally produced if it is less than 400 miles from its origin or within the state in which it was produced. A consumer survey carried out by the research firm Nielsen found that most buyers classify products across various food categories made 50 miles or less from the store, as local.

Local sources of produce are not confined to farms or small-size plots of land; They also include specialist operations such as high-tech commercial greenhouses and urban gardens. The enterprises sell directly to consumers or to retail customers such as supermarkets.

The size of the market for local food is unclear. From an industry standpoint, research from the Congressional Research Service (CRS) estimates that direct-to-consumer food sales account for about 3% of the total US agricultural production value. Up to one-half of the produce industry relies on sales to supermarkets and other chain stores, and the remainder serves foodservice companies (e.g., restaurants) and large consumers of produce such as schools and other institutions.

Pre-pandemic drivers

The localization movement was gathering steam in produce markets before the COVID-19 pandemic.

One of the drivers is the need to make produce supply chains more resilient to disruptions, like market volatility and labor shortages. Local sourcing avoids the risks associated with shipping perishable product long distances from growers to consumers. Also, shorter supply chains are more flexible, require fewer product touches and intermediaries, reduce wastage, and minimize potentially costly and delay-prone cross-border movements. There are cost advantages as well, mainly in the form of reduced transportation and warehousing costs.

Localization is finding support among consumers. Trust in food crops grown on distant, large-scale factory farms has declined as consumer interest in the safety and origins of food products has increased. Another component of this trend is the increased demand for sustainable products. For example, research by The Center for Food Integrity suggests that concepts such as “food miles” are becoming more relevant to consumers, as they place more value on shorter, more carbon-efficient supply chains.

The localization movement also aligns with the need to provide underserved communities with sources of fresh, nutritious food. One way to combat the spread of so-called food deserts – communities where access to fresh fruit and vegetables is limited – is to connect these communities with local growers.

These forces drive demand for locally grown fruits and vegetables and increase the premium that consumers are willing to pay for “locally produced” and “farm to table” product labels.

Coronavirus-related market shifts

Today, the COVID-19 crisis is reinforcing many of these market changes by illuminating weaknesses in produce supply chains. The pandemic shuttered restaurants and other places where large numbers of people congregate such as schools – effectively depriving fruit and vegetable producers of a primary market.

An obvious response was to pivot to other customers, notably supermarkets and other retail outlets. However, these are different channels with distinct specifications for product packaging and unit sizes. Reorienting supply chains geared to foodservice and institutional buyers towards customers in the retail business proved extremely challenging. To solve this issue, some farmers turned to selling their produce directly to the consumer, highlighting the value of locally produced foods as a source of revenue for farmers during supply chain disruptions. Some farmers may never go back to the original model.

The pandemic also exacerbated the labor shortages that plague growers in agricultural regions of the US. Restrictions on migrant workers crimped the supply of labor before the pandemic. The coronavirus’s health threat made it even more difficult to recruit the workers that growers need to harvest and pack food crops.

While localization does not address all pandemic-related supply chain issues, it does promote the flexibility, agility, and resilience needed to mitigate the risks associated with COVID-19 disruptions. This is one reason why the pandemic has underscored the advantages of local sourcing, especially for perishable products such as fruit and vegetables.

Moreover, preference for neighborhood markets may grow beyond food deserts. A recent study from mathematician Elena Polozova indicates that buying in corner stores is less risky than in big retail formats.

Innovations hone local models

The localization movement also benefits from a number of supply chain innovations in the agricultural industry. Here are some notable examples.

Local supply programs. As NPR reported recently, the movement known as community-supported agriculture (CSA) is experiencing growth in various parts of the country. Members of CSA programs typically commit to buying regular deliveries of fresh produce from local growers. The coronavirus pandemic has raised the profile of CSAs for the reasons described above, although the model is mainly growing in wealthy communities. 

Veggie box models. The so-called veggie box model is an evolution of the CSA movement. In this variation, groups of farmers create boxes of produce items in accordance with consumer preferences. 

Commercial veggie box models such as HelloFresh are expanding, and provide a new buying channel for fresh produce. However, they do not offer the variety and quantity that most customer segments need. In addition, these services are configured for middle-to-high income population segments and assume that there is enough last-mile delivery capacity to perform dozens of deliveries effectively. However, the capacity is not always available, a problem exacerbated by the COVID-19 crisis.

Dr. Chris Mejia, Dr. Lars Sanches, along with master’s students Jamal Taylor and Luiz Barreto from the MIT Food and Retail Operations Lab have collaborated with colleagues from Tufts University, and the City of Somerville, MA, to explore the veggie box model, in underserved communities. The options under review use neighborhood markets as pickup points for veggie boxes, analyze the impact of ride-sharing systems, and extend the impact of grocery delivery models in the city. Despite its complex design, the researchers found that the veggie-box model can support a local economy, decrease food insecurity, and address shortages of healthy food items. However, neighborhood market owners or managers need to widen the choice of produce, promote the veggie box service to the appropriate customers, and allocate space to store the boxes of produce.

A future article in this series on food supply chains will give a detailed account of the veggie box research described above.

Innovative growing models. Growers are harnessing novel agricultural methods such as hydroponics, advanced sensing, and information technologies to develop alternatives to traditional farms. An example is BrightFarms, a company that grows produce sustainably in high-tech, hydroponic greenhouses located in Pennsylvania, Ohio, Illinois, and Virginia. The greenhouses typically supply local supermarkets. In January 2020, the company opened a 280,000 sq. ft facility in Selinsgrove, PA, that can deliver over 2 million pounds of fresh, local produce year-round in PA and the PA-NJ-DE tri-state area. It has partnered with local supermarkets, including the Giant chain.

Urban and Container Farms. Small urban farms that sell to retail, food service, or restaurants have also become increasingly common with open fields, rooftops, brownfields, and other open spaces being utilized in cities to grow fresh fruits and vegetables. Urban farms that serve public demand reduce product transit and storage needs and increase food freshness in most cases.

Container farms use shipping containers to create self-contained growing environments for fresh produce, often in urban settings. One example is FreightFarms, which provides the container and set up that enable people to grow produce anywhere in the world.

Diversity programs. Traditional farmer’s markets allow residents to shop for a variety of produce items at specific locations in city locations at weekly times. However, these markets may not cater to the fruit and vegetable needs of ethnically diverse communities. World Farmers Organization in Massachusetts is implementing an innovative strategy to support culturally diverse farmers who grow their preferred products in small parcels and connect them to retail outlets. Some of these outlets are located in neighborhood markets. 

Small growers, big potential?

While the localization of fruit and vegetable supply chains is attracting interest, most conventional, large-scale growing operations are not under threat.

Not all food crops are viable candidates for small, local suppliers. Moreover, the competitive advantages of localization are subject to tradeoffs between economies of scale, the capital cost of growing facilities, and transportation costs. Also, more emphasis on locally grown produce increases the importance of supply chain transparency. Consumers who buy local produce want to be reassured that their purchases are sourced locally, and this will require relevant sourcing information at the point of sale.  The availability of investment funds also influences the commercial success of localization – a factor that could become more critical while the US economy remains mired in recession.

Still, consumers switching to local growers pre-COVID, in combination with the changes wrought by the pandemic, are creating a significant market for locally sourced produce that poses new supply chain challenges and opportunities. Researchers across MIT CTL are working on research projects to better understand this trend.

VIDEO: Fulop Elaborates on Jersey City’s Vertical Farming Program, The First of its Kind in The Nation

Jersey City Mayor Steven Fulop elaborated on the city’s vertical farming program, the first of its kind in the nation and the fourth overall across the globe, during an interview this afternoon.

“The last couple of months have highlighted that diabetes, obesity, high blood pressure, and heart disease make people more at risk and that’s more prevalent in communities that have less access to healthy food,” Fulop said.

“So we though running large-scale program that incorporates education and diet, which a lot of people don’t know about, with access to food that can hopefully change habits.”

The city will be joining forces with AeroFarms, a Newark-based vertical farming facility, to help make the effort successful.

“Societies’ structural food problems have become more clear with COVID-19.  The world needs more distributed, localized food production systems. We also need new ways to get healthy food to our most disadvantaged members of society,” stated AeroFarms CEO David Rosenberg.

Yesterday, the city announcing that there would be 10 farms throughout the city, which are estimated to produce 19,000 pounds of produce a year.

This afternoon, the mayor indicated that two of the locations will be within the Jersey City Public Schools, with the specifics to be determined at a later date, one at Marion Gardens, along with City Hall and the Bethune Center. The remaining locations are still pending.

In addition to the partnership with AeroFarms and the Health and Human Services Department overseeing the program, the World Economic Forum – who describes themselves as “an organization for public-private cooperation” – will also be a key component of the operation.

“We know diet is a key predictor of life expectancy and the Coronavirus has made clear the huge inequities on food access and food education that exists in different communities,” HHS Director Stacey Flanagan said in a statement.

“ … In collaboration with both private-public sector stakeholders, the initiative aims to catalyze new ecosystems that will enable socially vibrant and health and well-being centric cities and communities,” added Head of the Healthy Cities and Communities initiative at the WEF Mayuri Ghosh.

Some residents had questioned what the healthy eating workshops and health-monitoring component of the program would entail and Fulop elaborated today when asked about the particulars.

“It’s not new to have an education component with a city program … just recently, around a similar healthy food initiative – healthy food classes around supermarket shopping. And subsequent to that, we gave vouchers to have people shop with information that they just learned,” he explained.

“It’s important to change habits and incentivize people to do that and at the same time, give them mechanisms to track the progress. So we’re thankful for Quest Diagnostics, which is one of the largest labs in the world on this front and they’re going to help us track and of course keep patient confidentiality.”

Agrihoods and Access To Healthy Food

Written by Tinia Pina | Re-Nuble

The question has always been there: city life or country life? However, in the 1850’s, in response to a rising urban population and as a result of improved transportation methods, the suburbs began to sprawl out from large metropolises. Now, roughly 80 percent of Americans live in urban areas. Yet, the demand for closed-loop food processes continues to increase. Urban area citizens still want access to sustainable and healthy food systems. 

Defining Closed-loop Systems

By definition, a closed-loop system is one in which the operation is regulated by feedback. To clarify, feedback, in this sense, means that a portion of the output is fed back into the system to act as part of the excitation. The output cannot exist independent of the feedback.

Closed loop food systems produce high-quality, healthy foods using less energy and less water. When locally-sourced, their production and sale contributes positively to local economies and develops pride within the community.

Agrihoods and Access to Healthy Food

Enter agrihoods: the community feeling of suburbia mixed with the progressive thinking of the city sprinkled with the splendor of the country. There are several reasons people are drawn to this style of living. First and foremost is access to locally grown, sustainable food. A close second is the closed-loop process: the inhabitants enjoy the crop and the remains are composted for use as fertilizer. There is an eloquent beauty in the cyclical nature of closed-loop food processes.

In addition to providing sustainable, locally-sourced food, agrihoods provide steady work for farmers who gain access to affordable farmland in exchange for their services. Most farmers rarely enjoy a steady salary; this is not true for those employed by agrihoods. Most earn a salary of $35,000 to $100,000 annually and receive free or reduced housing.

While these little utopias are springing up all over the country, they remain out of reach for many Americans that either cannot afford the amenity of living in a neighborhood with a resident farmer or who simply prefer to live in the bright lights.

However, the opportunity for a closed-loop food process can exist even in the middle of Manhattan, giving urban areas access to healthy food. Soilless systems provide a closed-loop, sustainable method of food production that is as valuable to communities as it is to farmers. Soilless systems can be established indoors or out and can take on any size. Additionally, it requires less water to produce foods in a soilless system than in a traditional, soil-based system because water is continuously circulated; not lost to runoff.

Soilless Systems Provides Healthy Food Access for Urban Areas

Recent studies have shown that indoor, soilless systems require up to 90% less water than traditional farming methods. By keeping the plants at optimum conditions throughout the growth cycle, they are better able to utilize nutrients and produce more fruits and vegetables per gallon of water used.

Consumers reap the benefits of locally-sourced, organically grown produce while farmers enjoy a sustainable production method. These systems remedy some of the challenges presented to those that attempt to bring in healthy, locally-sourced produce to urban areas; such as zoning and infrastructure.

However, what has been missing in most soilless systems is true feedback. The fertilizers and growth nutrients used in most systems are petroleum-derived and chemical-based. They are produced in a lab and have nothing to do with repurposing food waste. They fail to take advantage of the nutrients that exist in food waste.

Access to high-quality, bio-derived agricultural materials is challenging, especially for farmers and hobbyists that utilize alternative growth methods. Re-Nuble was developed to meet this need. Re-Nuble products are 100% bio-based, sourced from vegetative food waste, meaning that everything that goes into making Re-Nuble comes from plants; there are no petroleum-based ingredients. As we continue to carry out our own R&D, we hope to identify even more ways to help soilless farms regulate their operations through feedback, providing urban areas with access to healthy food.

Variety of Healthy Foods From Vertical Farming Platform

When talking about technology, it's easy to focus on things like computers, smartphones, apps and the growing number of smart gadgets around the house. But technology is far-reaching and can influence and change traditional sectors quickly, one of them being the agricultural sector.

One company that is looking to take on the commercial agricultural industry is Eden Green Technology, just out of Texas. This company focuses on sustainability in the food industry. Eddy Badrina, CEO of the company tells about what they do, how they use technology, and how they envision the future of the agricultural industry.

Efficient use of space
"Eden Green Technology is a vertical farming platform that grows large quantities of local produce safely, sustainably, and efficiently. We use less land, energy, and water than both traditional farming and other indoor solutions. Our greenhouses are constructed on small footprints, in urban or suburban areas, to provide stable jobs and produce non-GMO, pesticide-free produce, which goes from farm to table in as little as 48 hours, compared to the 14 days it usually takes under the traditional model," Eddy says.

The founders of Eden Green are brothers Jacques and Eugene van Buuren. They came to the US to secure investment, source talent, and experiment with their technological solutions in diverse climates. They started in Texas, with its own extreme range of environmental considerations, agricultural know-how, and business opportunities, and built from there. 

Technology company
"Our technical secret sauce consists of a few ingredients, including our patented vertical “vines,” where our produce grows, and the way we create microclimates for each individual plant with temperature-controlled air and nutrient-enriched water. We also designed and built a proprietary mechanical, electrical, and plumbing solution specifically to automate and remotely monitor all our greenhouses. Because of that hardware and software combination, we like to think of ourselves as a technology company that happens to grow produce."
