Controlled Environment Agriculture Funding Breeds Optimism For Post-Pandemic Growth

Carrie Meadows

July 9, 2021

Back in 2019, LEDs Magazine published a feature on investment pacing and market prospects for horticultural solid-state lighting (SSL) and products and systems for controlled environment agriculture (CEA) operations. We were really just beginning to see how venture capital funds and research grants were being distributed among CEA growers themselves in a wave hot investment for advanced farming methods. Indeed, as chief editor Maury Wright wrote regarding the early planning days of the former Horticultural Lighting Conference, “We suspected the primary interest would be investment in the companies supplying technology that could be deployed in vertical farms around the globe. Instead, the sector would soon witness huge investment in the farms themselves.”

Although the pace of announcements slowed slightly amid the coronavirus pandemic, we have covered quite a bit of research on plant science, optimization studies for horticultural lighting, and capital investment alike. And I am pleased to see prospects are growing for companies working toward technology integration in this sector.

For example, the Wells Fargo Foundation’s Wells Fargo Innovation Incubator (IN2), which is co-administered by the US National Renewable Energy Laboratory (NREL), just announced the latest cohort of startups that will benefit from its funding and partnerships with NREL and an independent research institute, the Donald Danforth Plant Science Center in St. Louis, MO. All of the companies in this phase are focused on enabling sustainable indoor agriculture.

GrowFlux CEO Eric Eisele was kind enough to point me to the program news, which you can read in the linked release on our site. For background, GrowFlux is a 2021 LEDs Magazine Sapphire Awards finalist for its GrowFlux Dimmer lighting controller. That product is designed with ease of use in mind to allow an end customer to easily deploy intelligent controls without programming experience or a technician to set up.

“With the growing complexity and evolving practices around horticultural lighting control, our user-friendly setup experience and app eliminates a lot of the frustration,” said Eisele. “We've been building out compatibility for all of the major manufacturers of horticultural lighting to make this energy-saving control technology as accessible as possible, especially for the many small and medium-sized businesses in the controlled environment agriculture industry.”

Each participating company in the IN2 cohort will receive $250,000 and will work at NREL and the Danforth center on R&D. When asked what GrowFlux plans to do with its funding, Eisele said that the company will partner with a sensor manufacturer to combine wireless controls and PAR sensors to determine real-time PAR levels in the indoor environment. The idea is to analyze the PAR data and program the lighting control system to evaluate and manage a Daily Light Integral (DLI) target.

The word “automation” came up. GrowFlux is not the first organization to explore the concept of bringing software intelligence, lighting, and systems controls together in a way that delivers both streamlined and adaptable operations to reduce energy consumption in a greenhouse or other CEA setting (refer to the Automatoes challenge and a presentation from AgEye in our past HortiCann Light + Tech insights). However, Eisele explained, the GrowFlux wireless dimmer is compatible with offerings from many well-known horticultural lighting providers (e.g., Fluence, GE Current, BIOS, Heliospectra, and more), and the company intends to maintain out-of-the-box installation and interoperability with the next generation of technology development, rather than pursue customized designs.

Funding placements like this will propel advances for CEA and AgTech, increase technology uptake, and prove out the return on investment for integrated horticultural systems.

Vertical Farming: Disrupting Agriculture

A New Agricultural Revolution Could Forever Change The Planet

ROBBY BERMAN

24 May 2021

• Vertical farming leverages cutting-edge technology to grow food in a new and better way.

• One of its many benefits is that it can increase crop yield by 700 percent.

• Vertical farming can help relieve pressure on scarce resources and boost Earth's biodiversity.

One day soon, you could eat bananas grown in downtown Manhattan.

It's a way of growing food that turns traditional agriculture on its head. With the required technologies now rapidly maturing, vertical farming is sprouting across the globe.

While there are still unresolved issues with this marriage of technology and agriculture, its promise may be irresistible. If it gets off the ground — literally — in a major way, it could solve the problem of feeding the Earth's 7.9 billion people. And that's just one of the benefits its proponents promise.

Agriculture through time

When humankind began planting crops for nutrition about 12,000 years ago, the nature of our hunter-gatherer species fundamentally shifted. For the first time, it's believed, people began staying put.

With agriculture as their central mission, communities formed, with the now-familiar arrangement of residential areas surrounded by land dedicated to growing food. Even today, with modern transportation making the widespread consumption of non-local foods common, this land-allocation model largely survives: population centers surrounded by large areas for growing vegetables and fruit and raising livestock.

Challenges facing traditional agriculture

As our population has grown, traditional agriculture has begun facing some big challenges:

• Farmland takes up a lot of space and destroys biodiversity. Our World in Data reports that half of all habitable land is used for agriculture. As Nate Storey of Plenty, Inc., a vertical farming startup, puts it, "It is probably one of the most defining acts of humanity: We literally changed the ecosystem of the entire planet to meet our dietary needs."

• The demand for farmland — both for produce and livestock — has led to a dangerous deforestation in several parts of the world. This also results in biodiversity loss and contributes to an increase in the greenhouse gases that drive climate change.

• Degradation of farmland, such as through soil erosion, poses a threat to agricultural productivity.

• Agriculture consumes copious amounts of water, which exacerbates water shortages. (Obviously, water shortages also reduce agricultural productivity.)

• Fertilizer run-off causes substantial environmental damage, such as algal blooms and fish kills.

• Pesticides can degrade the environment by affecting non-target organisms.

• The effects of climate change are already making agriculture more challenging due to significant shifts in weather, changes to growing seasons, and realignment of water supplies. Our climate is continuing to change in unexpected ways, and the only predictable aspect of what lies ahead is unpredictability.

Vertical farming proponents expect that a re-think of how we grow food can ultimately solve these problems.

What is vertical farming?

Vertical farming is a form of agriculture that grows plants indoors in floor-to-ceiling, tower-like walls of plant-holding cells. Instead of growing plants in horizontal fields on the ground, as in traditional farming, you can think of vertical farming's "fields" as standing on the edge and extending upward toward the ceiling. The plants need no soil or other aggregate medium in which to grow; their roots are typically held in a cell lining, often composed of coconut fiber.

Vertical flora is grown either aeroponically, in which water and nutrients are delivered to plants via misting, or hydroponically, in which plants are grown in nutrient-rich water. These are incredibly efficient systems, requiring 95% less irrigation than soil-grown plants. With vertical farming, Storey says that 99 percent of the moisture transpired by plants can be recaptured, condensed, and recirculated.

Plants, of course, also need light to grow, and vertical farms use increasingly efficient LED bulbs to keep plants thriving.

Vertical farms can increase crop yields by 700 percent

If vertical farming takes off the way its supporters believe it should and will, it may solve many of the aforementioned challenges facing agriculture.

Crop yields with vertical farming far exceed what's possible with traditional agriculture. Plenty, Inc.'s Shireen Santosham notes that the highly controlled growing environment of vertical farming has allowed her company to reduce the growing time for some crops to as little as 10 days. Without needing to consider whether or even sunlight, combined with the ability to operate 365 days a year, their system increases the potential annual yield by about 700 percent.

The land requirement for vertical farming is a mere fraction of that for traditional agriculture. Santosham says it can be done in a building the size of a big-box retail store that can be built pretty much anywhere that has adequate utilities, including within major urban centers. The tightly controlled environment of a vertical farm should also eliminate the need for applied pesticides.

Yet another benefit of vertical farming is the return of land currently needed for food production back to the planet. This could help facilitate Earth's recovery from deforestation and return much-needed habitat to threatened or endangered species. Of course, if we ever colonize the moon or Mars, vertical farming will be the go-to option for feeding the colonists.

Several vertical farming company pioneers are already getting their high-quality crops into the hands, and mouths, of consumers. Plenty, Inc. has an eponymous line of greens, and Aerofarms has their FlavorSpectrum line. Both companies claim that their products are exceptionally tasty, a result of their carefully controlled growing environments in which computer-controlled lighting can be optimized to bring out the most desirable qualities of each crop.

The history of vertical farming

The idea of vertical farming isn't new, and experts have been questioning its viability since the term was first coined in 1915 by Gilbert Ellis Bailey, who was obviously way ahead of the available technology at the time. The first attempt to grow produce in a constructed environment was a Danish farmhouse factory that was built to grow cress, a peppery green related to mustard, in the 1950s.

The modern concept of a vertical farm arose in the New York classroom of Columbia University's Dickson Despommier in 1999. He presented the idea as a theoretical construct, a mental/mathematical exercise imagining how to farm in an environmentally sound manner. His class began with the notion of a rooftop garden before considering a "high-rise" version that might theoretically be able to grow enough rice to feed two percent of Manhattan's population at the time. The eureka moment was a question Dispommier asked: "If it can't be done using rooftops, why don't we just grow the crops inside the buildings? We already know how to cultivate and water plants indoors."

With the technological advances of the last few decades, vertical farming is now a reality. Our sister site, Freethink, recently paid Plenty, Inc. a visit. (See video above.)

Vertical farming today

Today, growers across the globe are developing vertical farms. While the U.S. has more vertical farms than any other country, the industry is blooming everywhere.

There are currently over 2,000 vertical farms in the U.S. While more than 60 percent of these are owned by small growers, there are a few heavyweights as well. In addition to Wyoming's Plenty, Inc. and Newark's Aerofarms, there's also New York's Bowery Farming. There are also companies such as edengreen, based in Texas, whose mission is to help new entrants construct and operate vertical farms.

Japan comes in second, with about 200 vertical farms currently in operation. The largest vertical farming company there is SPREAD. Across Asia, vertical farms are operating in China, South Korea, Singapore, Thailand, and Taiwan. In Europe, vertical growers are in Germany, France, Netherlands, and the U.K. Germany is also home to the Association for Vertical Farming, "the leading global, non-profit organization that enables international exchange and cooperation in order to accelerate the development of the indoor/vertical farming industry."

In the Middle East, whose desert land and scarcity of water present a particularly challenging agricultural environment, vertical farming is taking root, so to speak. The United Arab Emirates' Badia Farms is now producing more than 3,500 kilograms of high-quality produce each day and expects to increase that yield going forward. In Kuwait, NOX Management launched in the summer of 2020 with plans to produce 250 types of greens, with a daily output of 550 kg of salads, herbs, and cresses.

The economics of vertical farming

Building and operating a vertical farm is a costly endeavor, requiring a substantial initial investment in state-of-the-art technology, real estate, and construction. AgFunderNews (AFN) estimates that it can cost $15 million to construct a modern vertical farm. Fortunately, investors see the potential in vertical farming, and the industry has attracted more than $1 billion in investments since 2015. That includes $100 million for Aerofarms. Plenty, Inc raised $200 million in 2017 from a fund backed by such respected forward-thinkers as Jeff Bezos and Alphabet chairman Eric Schmidt.

AFN is particularly excited by the potential of what they call second-generation vertical farming technology. They cite advances in LED technology — expected to increase energy efficiency by 70 percent by 2030 — and increasingly sophisticated automation that can streamline the operation of vertical farms. AFN anticipates operating cost reduction of 12 percent due to improvements in lighting and another 20 percent from advances in automation.

BusinessWire says that the vertical farming produce market was valued at nearly $240 million in 2019, and they expect it to grow 20 percent annually to over $1 billion by 2027.

A welcome disruption

Vertical farming will be disruptive.

Vertical farming would eliminate the need for the arduous work of harvesting crops by hand from vast tracts of farmland. Current picking jobs, the company says, can be replaced by better-paying, full-time jobs available 365 days a year in better working conditions — and in the variety of geographic locations in which vertical farms can operate.

There are two caveats, however. First, the number of people needed to manage and harvest vertical farm crops will be far fewer than the many farmworkers required for less efficiently planted traditional fields. Second, with automation becoming ever-more capable — and perhaps a key to eventual profitability — one wonders just how many new jobs ultimately will be created.

But the societal benefits far outweigh any costs. As Plenty's Storey muses, "Like most everything in the world, we can only save our species if it makes economic sense." Thankfully, it does make economic sense

Kalera Announces The First Harvest For Atlanta Vertical Farming Facility That Will Produce Over 10 Million Heads of Lettuce Per Year

The new facility will supply schools, restaurants, grocery stores, hospitals, retailers, and more with safe, fresh, nutrient-dense, locally-grown greens

April 27, 2021

Source: Kalera

ATLANTA, April 27, 2021 (GLOBE NEWSWIRE) -- Kalera (Euronext Growth Oslo ticker KAL, Bloomberg: KSLLF), one of the fastest-growing US vertical farming companies in the world and a leader in plant science for producing high-quality produce in controlled environments, today celebrated their first harvest in their Atlanta-area facility. Its largest farm to date — and the largest vertical farm in the Southeastern United States — the facility is 77 thousand square-feet and has the capability of producing over 10 million heads of lettuce per year. Located in Forest Park, GA, the farm was built in just eleven months thanks in large part to the company’s modular building approach and has created dozens of new jobs in the Atlanta area.

“Our new Atlanta facility is open and performing in line with our expectations and we are eager to begin offering our local, fresh, safe, sustainable greens to the Georgia market,” said Daniel Malechuk, CEO of Kalera. “Our customers are telling us that there has never been a better time to ensure supply continuity, locally, than now and we are grateful Kalera can provide this.”

Kalera’s optimized nutrient and light recipes allow them to grow high-quality, pesticide-free, non-GMO produce at accelerated growth cycles. Planting at the Atlanta facility began in early March, and the first harvest began successfully last week. Kalera has so far experienced optimal operating efficiencies in Atlanta, particularly in terms of lighting productivity. All growth systems, environmental equipment, and technology have operated effectively since opening the facility on March 11. Due to strong sales indications in the region from both retail and foodservice customers, Kalera is implementing a faster ramp-up schedule than originally planned.

The facility’s location near the urban center of Atlanta cuts down on travel times for retailers, restaurants, and other customers who want access to the freshest, non-GMO, clean living lettuces and microgreens. Royal Food Service, a leading produce distributor in the state, is one of Kalera’s top partners bringing “pick-to-plate” greens to restaurants, hotels, schools, and other businesses including Ansley Golf Club, The Ritz-Carlton at Reynolds, Lake Oconee, The Georgia World Congress Center, several restaurants and many others. The lettuce is also available on the shelves of Publix Supermarkets.

“As the former Governor of Georgia, I could not be more excited that Kalera’s delicious greens are now available in the Atlanta area,” said Sonny Perdue, former U.S. Secretary of Agriculture, who joined Kalera’s Board of Directors earlier this year. “Kalera is leading the pack in a booming vertical farming industry. It’s a perfect example of the power of American innovation, creativity, and entrepreneurship to develop different, innovative ways to grow and provide food at home and around the globe.”

Kalera currently operates three growing facilities – two in Orlando and one in Atlanta and is building facilities in Houston, Denver, Columbus, Seattle, Minnesota, and Hawaii. Kalera is the only controlled environment agriculture company with coast-to-coast facilities being constructed, offering grocers, restaurants, theme parks, airports, and other businesses nationwide reliable access to locally grown clean, safe, nutritious, price-stable, long-lasting greens. Once all of these farms are operational, the total projected yield is several tens of millions of heads of lettuce per year. Kalera uses a closed-loop irrigation system which enables its plants to grow while consuming 95% less water compared to field farming.

Recently, Kalera also acquired Vindara, a seed company that uses genomics, machine learning, and computational biology along with traditional breeding methods to meet the market need for produce that is non-GMO, nutritious, high-yielding, and delicious. Explicitly intended for the new high-tech indoor growing environments, Vindara seeds offer growers the opportunity to capitalize on significantly higher yield potential, production efficiencies, and product customization — in a fraction of the time through reducing the grow cycle.

ABOUT KALERA
Kalera is a technology-driven vertical farming company with unique growing methods combining optimized nutrients and light recipes, precise environmental controls, and cleanroom standards to produce safe, highly nutritious, pesticide-free, non-GMO vegetables with consistently high quality and longer shelf life year-round.

A New FEZ "Karakalpak-Agro" Established In Uzbekistan

Tashkent, Uzbekistan (UzDaily.com) - The Cabinet of Ministers adopted a resolution”On measures to organize the activities of the free economic zone “Karakalpak-Agro”.

In accordance with the decree of the President “On measures for the comprehensive socio-economic development of the Republic of Karakalpakstan in 2020–2023” on an area of 875.4 hectares in Amu Darya, Buzatausky, Kegeili, Konlikul, Kushgirot, Muynak, Nukus , Takhiatash, Turtkul, Khodjeyli, Shumanai and Ellikala districts, the SEZ "Karakalpak-agro" was created.

The functions of managing the activities of the FEZ "Karakalpak-Agro" are assigned to the State Unitary Enterprise "Directorate of the free economic zone" Nukus ".

The main tasks and directions of the SEZ "Karakalpak-Agro":

- attracting direct foreign and domestic investments for organizing modern greenhouses on a cluster basis, including hydroponic ones, as well as organizing the production of structures, equipment and other components for the construction of modern energy-efficient greenhouses;

- increasing the production of agricultural products, expanding its deep processing and increasing exports, effectively using the production potential of the region;

- encouraging the organization of the complete process of agricultural production from seeds to delivery to the market;

- introduction of effective mechanisms for providing greenhouses with seeds and seedlings of high-yielding crops demanded by the market, by creating conditions for organizing nurseries, as well as seed production;

- formation of a modern infrastructure for the provision of logistics services, assistance to agricultural producers in organizing the export of their products;

- widespread introduction of modern resource-saving technologies, the use of alternative sources of thermal energy in the organization of greenhouses;

- creation of research and production centers to assess the compliance of products with international standards.

The Council of Ministers of Karakalpakstan, together with the Ministry of Investments and Foreign Trade, the Chamber of Commerce and Industry and commercial banks, was instructed to develop a targeted program of facilities for the production of structures for greenhouses on the territory of Karakalpak-Agro within two months, with the allocation of vacant non-agricultural land.

BONAFIDE Will Continue To Develop It's Concept On Decentralized Agriculture And Food Supply Systems

Over the last 6 years, we have seen technology advance to facilitate urban vertical farming embracing entrepreneurial opportunities, the supply of fresh food daily, and secure cultural kitchens requirements for raw materials anytime anywhere.

At the same time conflicts, natural resource competition, and climate change have had adverse effects on food security that local production using new technology can alleviate.

The trend for decentralization is growing all the time and we trust that agricultural policies will follow suit to support local farmers and a new generation of young entrepreneurs that find their ideology in creating new markets.

These 2 Companies Are Putting Big Money Into Hawaii’s Agricultural Future. Will Their Bets Pay Off?

A pair of companies backed by a billionaire and a pension fund are trying to revitalize fallow farmland in the state.

View fullsize

By Brittany Lyte

02-15-21

On Lanai, where shreds of black plastic in the soil are the last vestiges of the island’s defunct pineapple fields, a sliver of long-abandoned farmland is getting an encore — and a reinvention.

In six high-tech greenhouses, a futuristic vision of food-growing is underway — one in which nutrient density and flavor are automated.

It doesn’t matter that the red dirt below the greenhouse is eroded or peppered with plastic that once served as Dole pineapple plantation’s weed control. In fact, the hydroponic tomatoes and leafy greens grown here by Sensei Ag don’t depend on soil at all. 

The ag-tech company founded by Larry Ellison, the Oracle founder who owns nearly all of Lanai’s acreage, and Dr. David Agus, a physician, and medical researcher, is pioneering tools to produce affordable food in places like Lanai that — despite its history as an agricultural plantation — lack traditional farming essentials like water and fertile soil.

Sensei Farms Lanai, a two-acre indoor farming pilot project by Larry Ellison’s Sensei Ag, produced 35,000 pounds of produce in less than three months last year. Sensei Ag

In doing so, the company is redeploying a scrap of neglected farmland into active agriculture in an attempt to buck an unsettling trend: Hawaii imports more than 85% of its food.

Hawaii has tens of thousands of acres of fallow former sugar and pineapple plantation lands. There are many reasons why this land isn’t being used for farming — inadequate infrastructure, soil erosion, the sky-high price of agricultural real estate. All of these challenges and more make growing food on old plantation acreage unaffordable for most farming operations.

Putting more of this stagnant acreage into food production, however, is a worthwhile goal, experts say, because it could help the state wean itself off of a reliance on the cargo ships and planes that deliver food supplies to the islands. 

“When you bring up Hawaii to anyone anywhere on earth, what they think of is paradise on earth,” said Vincent Mina, president of the Maui Farmers Union United. “But what paradise do you know of that brings in 85% of its food?”

State Efforts Have Fallen Short

Re-fashioning former sugar and pineapple plantations into viable food farms is what the Hawaii Agribusiness Development Corp. was designed to do. 

However, a scathing state audit in January said that the 25-year-old state agency has so far failed its mission because “the economic void created when plantations ceased production remains mostly unfilled.”

Larry Jefts, one of the state’s largest produce producers, recently expanded his farm footprint with access to ADC lands in Central Oahu that had lain fallow since Del Monte stopped pineapple production nearly two decades ago. 

The problem, according to Jefts, is not that the ADC is inert. It’s the state’s poor land use policy that has allowed some farmland to be developed, as well as society’s lack of commitment to local agriculture.

The Agribusiness Development Corp. has failed in its mission to reinvent Hawaii’s agricultural sector, two recent reports say. Office of the Auditor

“The problem is there’s no will here,” Jefts said. “Good farm ground is coming out to go into solar energy farms because the people who own it can make more money in solar. If they charged that much money to the farmers, the farmers would fail and imported foods would take over.” 

Yet while Jefts is farming on a portion of the 1,200-acre Whitmore Project — land left vacant by Del Monte in 2004 and then acquired by the ADC for local agriculture in 2012 — hundreds of acres attached to the project remain fallow almost 10 years later.

That’s in part due to the time-intensive, bureaucratic process of securing money, permits, and contracts to build and repair the infrastructure required to make more of the acreage farmable, said Sen. Donovan Dela Cruz, a champion of the project.

It’s one thing to acquire the land, he said. But it’s another challenge entirely to ready it for farmers who need water, roads, electricity for refrigeration, and food safety-compliant facilities in order to make their businesses financially viable.

“With our state, there’s so many good intentions but just no money to put through to implementation,” said Kirsten Oleson, associate professor of ecological economics at the University of Hawaii College of Tropical Agriculture and Human Resources.

“If we’re serious about doubling production of food that is grown and eaten here, it would take some time to rethink policy and some pretty large and potentially risky investment that the state’s coffers don’t have.”

While state efforts flounder, a pair of new agriculture companies backed by a billionaire and a pension fund are stepping in with lofty goals to revitalize fallow farmland with diversified agriculture operations that aim to help Hawaii wean itself off of imported foods.

A Billionaire’s Bid To Boost Food Security

On Lanai, Sensei Ag is sidestepping many of the traditional high-yield farming requirements: lots of land, lots of water, lots of hard manual labor.

View fullsize

Founded by Oracle billionaire Larry Ellison, left, and medical researcher David Agus, Sensei Ag’s goal is to grow food that is more sustainable and nourishing than if it were farmed traditionally.

Sensei Ag

Although the company’s two-acre greenhouse farm is just a scrap of the 20,000 farmed acres that earned Lanai the moniker of the world’s largest pineapple plantation, yields from hydroponics can be far greater than those from conventional soil farming.

Sensei Ag CEO Sonia Lo projects the company will harvest 500,000 pounds of food for statewide consumption in 2021, including Swiss chard, basil, tomatoes, cucumber and eggplant.

“What we’re doing is we’re competing against the likes of Organic Girl that’s coming in from California or Earthbound Farms,” Lo said. “It’s pretty straightforward given that our stuff is a day old or two days old by the time it gets on a shelf as opposed to two weeks or three weeks old.”

Hydroponic growing is capital-intensive, however. Sensei Ag’s approach benefits from the fact that it’s bankrolled by Ellison, one of the richest people in the world.

Lo declined to reveal the amount of financial investment it took for the Lanai pilot project to achieve its inaugural harvest last October, but she acknowledged the role of Ellison’s wealth.

Yet while the cost to build a state-of-the-art greenhouse is out-of-reach for most farmers, indoor farming offers growers a chance to capture significant long-term financial savings since producing food this way requires significantly less land and water than traditional outdoor farming. 

According to Lo, Sensei Farms Lanai requires about 10% of the amount of water it would take to produce a similar harvest in the dirt.

With this in mind, Sensei Ag’s mission includes efforts to make greenhouse farming more accessible. The company is aggregating risk assessment data in hopes that it will encourage banks to finance indoor growing mechanisms such as greenhouses and vertical farms. The company is also writing a playbook for people who want to build a successful indoor farm business, Lo said.

The rise of this kind of high-tech, high-yield farming could be a key to making Hawaii-farmed foods more competitive, according to Jesse Cooke, vice president of investments and analytics at the Ulupono Initiative.

“Using a hydroponic system, you could guarantee that every week you would have the same amount of quantity and the same quality (of produce) — and that’s what you need to sell to a large grocer,” Cooke said. “A lot of outdoor operations can’t guarantee that because they’re at the whim of nature itself.”

Brian Miyamoto, executive director of the Hawaii Farm Bureau Federation, agrees that indoor farming could be a game-changer — if Hawaii farmers can figure out how to raise enough capital to build the infrastructure without sabotaging future profits.

“We can grow a lot of things here in Hawaii as far as food products,” Miyamoto said. “What we struggle with is doing it competitively — that’s why we import so much.”

Hawaii can’t rely on billionaires to make the upfront investment in high-tech indoor farming, Oleson said. Rather, the state needs to follow in the footsteps of other countries that enacted public policies to encourage this kind of agriculture.

In places like Israel and the Netherlands, high-tech greenhouses are important food production tools, Oleson said. 

Beyond policy and economics, Oleson said there are aesthetic and cultural considerations associated with scaling up indoor farming in the islands.

“You’re not looking across rolling green landscapes, you’re looking at lands with big infrastructure on it so there’s sometimes social pushback,” Oleson said. “I’m not a Native Hawaiian, but I would be very curious to know the response of the local community to that kind of agriculture because it’s very divorced from the earth.” 

Will Mahi Pono’s ‘Serious Amount Of Money’ Pay Off?

On Maui, a partnership between a California farm management company and a Canadian pension fund is producing food on fallow land resulting from the 2016 closure of the state’s last sugar grower.

Since Mahi Pono bought 41,000 acres of Hawaiian Commercial & Sugar Co.’s former sugar cane fields in 2019, the company has begun growing some of Hawaii’s top food imports — potatoes and onions — in hopes of winning over some of that market share. 

Mahi Pono’s mission to produce foods that Hawaii imports heavily and that are agriculturally possible to grow here is a smart one, according to Oleson. But she said it could be difficult for the company to compete with the price point for potatoes and onions imported from the mainland.

It might also prove hard to convince consumers to pay more for locally grown potatoes and onions as opposed to more perishable produce.

“Potatoes and onions can sit on a boat and the quality doesn’t decline quite as fast, but all of us know what happens when you buy a box of spinach from Costco and if you don’t eat it that night it turns to slime,” Oleson said. “So the concern is growing foods locally where the freshness really matters.”

But Mahi Pono is growing more than just root vegetables. The company planted over a half million avocado and breadfruit trees, as well as rows of trees to shelter crops from the wind. The company plans to plant its 1 millionth tree by the end of June, according to community relations director Tiare Lawrence.

The company is also growing produce ranging from tangelos and finger limes to broccoli and eggplants, and it’s leasing affordable land and water to small farmers for an annual fee of $150 per acre. 

Ultimately, Mahi Pono’s staple crops will be citrus, papaya, macadamia nuts, and coffee, Lawrence said.

And while the company is exporting papayas to Canada, and eventually plans to export coffee, macadamia nuts, and citrus to markets outside the state, the majority of the food produced by Mahi Pono will feed Hawaii’s people, Lawrence said.

“I personally think these lands can be brought into production,” Lawrence said. “We’ve seen it across Hawaii where farmers have been able to take former sugar and pineapple lands and turn it into a thriving farm and I refuse to entertain doomsday scenarios.”

But the farm enterprise faces many challenges. 

With an average wind speed of 30 miles per hour in the Central Maui plains, there are erosion issues, as well as crop damage from pests, deer, and pigs. 

“We really can’t plant a field unless we fence it in, so that adds to our costs,” Lawrence said. 

There’s also the problem of the former plantation’s aging, outdated infrastructure.

“Mahi Pono has spent a serious amount of money in updating the irrigation systems and making repairs to wells,” Lawrence said.

If Mahi Pono can surmount these challenges and find success, Cooke of Ulupono said the operation will be an example to follow.

“If they can get it up and running, that could be one of the hugest transformations that Hawaii has seen, especially going towards local food for local consumption,” Cooke said. “The worry is that it doesn’t work and somehow the land gets zoned residential and a housing development goes up.”

“Hawaii Grown” is funded in part by grants from the Ulupono Fund at the Hawaii Community Foundation, the Marisla Fund at the Hawaii Community Foundation, and the Frost Family Foundation.

Signify Adds Automatic Intensity Adjustment Plus Year-Long Recipe Modulations To Horticultural Controls

Mark Halper

Signify has enhanced the control system for its greenhouse LED lighting so that toplights can react immediately to changes in daylight conditions and adjust brightness accordingly. The company has also added year-long control settings intended to allow vertical farmers — but not greenhouses — to program seasonal variations in LED spectral content over a 365-day period.

Both upgrades are intended to reduce manual labor and improve overall cost efficiencies, Signify said.

Until now, greenhouse farmers could dim or brighten their Signify toplights by instructing the lights to do so via the control system, called GrowWise. Signify has now modified GrowWise software so that it can take readings from daylight sensors that are part of separate systems. GrowWise then instantly and automatically adjusts artificial light intensity emitted by the toplights, called Philips GreenPower LED.

“The lighting can be used much more efficiently since it gives us the flexibility to reduce light levels at any moment we need to,” said Wouter de Bruyn, the owner of Belgian lettuce grower De Glastuin, an early user of the new automatic feature.

Whereas Signify is known in office settings to build sensors into its smart luminaires, the GrowWise controls make use of sensors that are part of climate control systems and greenhouse management systems from companies such as Priva, Hoogendern Growth Management, and Ridder, all based in Holland.

Planet Farms’ Luca Travaglini backs up Signify’s point that prescribing a year of spectral content improves efficiency and helps keep down manual labor costs in controlled environment agriculture (CEA) operations such as vertical farms.

“The climate computer is equipped with a daylight sensor that sends actual light measurements to the GrowWise Control System so we can adapt our light levels automatically to ensure an even light level throughout the day and season,” de Bruyn said at De Glastuin, based in Kontich.

“Dynamic lighting in a greenhouse is the next step in improving the cost efficiency and quality for the cultivation process,” said Udo van Slooten, business leader, horticulture LED solutions at Signify. “It allows growers to effortlessly maintain a consistent level of light throughout the day to produce the best possible crops. The system compensates for cloudy weather and creates a more controlled growing environment for your crop.”

In another upgrade to GrowWise, vertical farmers who want to prescribe modulations in spectral content are no longer limited to 24 hours of looped recipe cycles. Rather, they can order up a year’s worth of shifts for controlled environment agriculture (CEA) operations.

The year-long programming feature is aimed at vertical farmers rather than at greenhouses because the lights that Signify provides for vertical farms support controllable spectral changes, whereas the greenhouse toplights do not. Signify refers to its GreenPower LED vertical farm lights as “production modules” rather than as “toplights.” Toplights and production modules can both be programmed for intensity over a year, but the intention of the year-long feature is oriented toward spectral content.

Compared to greenhouses, vertical farms tend to make much less, if any, use of natural light. In vertical farms, the lights are mounted much closer to the crop in stacked shelves.

One of the first users of the year-round feature is Italy’s greens and lettuce grower Planet Farms.

“Now we can easily create custom light recipes and set them to run year-round to provide the right light recipe with the right light intensity at the right time throughout the crop’s growth cycle,” said Planet Farms co-founder Luca Travaglini. “By automating our full light strategy during the growth cycle, for the whole year, we can run our operations very efficiently and keep our manual labor costs low. That makes it easier for us to maintain consistent quality as we scale up our production.”

The horticultural market is a key growth sector for Signify, especially as it maps out a strategy to maintain profits in the pandemic economy, in which last week it reported a yearly rise amid rigorous cost controls that now include a small number of layoffs. CEO Eric Rondolat is targeting a big chunk of what he has quantified as a $2 billion general horticultural lighting market by 2023.

Delivering The Optimal Growing Parameters

Growing a new variety
Indoor farming has numerous growing parameters to take into account. Particularly when growing a new variety, all variables should be perfected in order to reach an optimum yield. In an indoor space, experimenting with these environmental parameters might, however, seem tricky. But what about trying out this environment in a smaller setting, such as an experimental growth chamber?

Alexis is fully aware of the challenges that vertical farmers face. The environmental control needs to be as precise as possible, as the effect of different light spectra or nutrients may have a significant impact on crop yield and quality. With this challenge in mind, Grobotic Systems brings a new solution to the market: a compact and highly instrumented growth chamber. “It’s an experimental chamber rather than a farming chamber. Therefore, you won’t use it to grow vegetables, but you can use it to identify which growing parameters are best suited to your crops,” Alexis says.

On your desk or under your bench 
According to Alexis, the chamber fits on your desk or under your bench. It can apply any environmental condition preferred, including light spectra and temperature. Internet connection via the growth chambers allows users to monitor plants on their cellphones via integrated cameras and other sensors inside the chamber.

Another advantage of the chambers’ size is that they can be stacked in an array, adjusting variables in each chamber. In this way, a multi-variable experiment can help users identify which environment works most optimally for their intended crop. “When using a large cultivation room, it is hard to split the room into different temperatures. A smaller cultivation space, such as our growth chambers, can be placed anywhere, just like a personal computer. Moving away from the large expensive capital equipment and machinery to small and stackable experimental chambers saves a lot of space and money.”

Alexis first came up with the concept of the growth chamber during his PhD and postdoctoral work in plant genetics. Several prototypes are currently being used at research institutes and start-up companies. Grobotic Systems is working on a more advanced growth chamber that will be launched in the summer of 2021: “We are integrating feedback from the deployed prototypes into the design of the advanced chamber, and we will start marketing the advanced chamber later this year.”

Large-scale farms
Not only new farmers can benefit from running small-scale experiments in a growth chamber, but also large-scale, established farms, since the chamber allows them to experiment with new varieties, creating the optimal yield. This will in turn enable them to upscale their production. “Not all farmers like to invest their time in carrying out experiments, as some trust that the vertical farming technologies they buy will always work for them. However, in the end it could save them a lot of money. No one needs to use productive farm space to do the experiments, just a few manageable boxes can suffice.”

This Startup Wants Vertical Farmers To Hire A Robot Gardener

In recent years, vertical farming has emerged as a futurist’s solution to the world’s agricultural problems. The growing trend seeks to use controlled environments to boost food production, leveraging indoor labs where temperature, light, and nutrients can be mechanically controlled.

Yet while vertical farms have gained in popularity, they are also still very expensive. When compared to conventional farming, these farms necessitate the purchase of pricey equipment to aid human labor—a fact that, when paired with other economic pressures, has apparently led to an industry “littered with bankruptcies.”

One company hopes to change this dire picture. Enter Watney the robot.

Watney was designed by start-up Seasony. The company, which was featured today at this year’s Alchemist Accelerator’s Demo Day, has sought to make the tech-farming trend more accessible by automating away some of the more difficult labor involved.

“By automating the production with robotics and remote monitoring, we can lower labor costs and offer solutions for food producers that is economically viable and environmentally sustainable,” the company claims on their website.

Indeed, Watney is designed to augment (and, in many ways, replace) a human labor force—currently one of the biggest expenditures for vertical farms. Essentially an intelligent, automated cart, the robot was designed to “move and transport plant trays” within a farming hub. In techno-jargon, it is an autonomous mobile manipulation robot (AMMR), a type of machine known for moving and manipulating items on its own. It is also equipped with a camera that captures image data and sends it back to farm management software for human analysis. Watney also gathers valuable horticultural data to help farmers optimize yields, said Christopher Weis Thomasen, Seasony’s CEO and Co-Founder, in an email.

“We are doing for vertical farming what the integration of autonomous mobile robots did to amazon. We are able to decrease the costs of growing food in a vertical farm by alleviating the logistics pains of working from scissor lifts,” said Thomasen.

Thomasen, a mechanical engineer, and his two co-founders electrical engineer Servet Coskun and business specialist Erkan Tosti Taskiran, were inspired to create the business while brainstorming what it would take to sustain life in outer space (Watney the robot is named after Mark Watney, the astronaut in the movie The Martian, who, after being stranded on the Red Planet, fertilizes potatoes with his own poop to survive).

“It quickly evolved to Seasony setting up a vertical farming lab and exploring the technical challenges facing the new industry. Reducing the costs related to labor is key in order to scale vertical farming and make agriculture more sustainable,” Thomasen said.

There is, of course, some debate in the farming community about the social costs incurred through the large-scale displacement of human labor.

Presumably, we will have to wait to see what that cost-saving process looks like. Seasony, which is still getting off the ground, plans to do a pilot trial with the largest vertical farm in Europe in April. It has plans to conduct further testing with several smaller vertical farms, as well, Thomasen said.

VIDEO: Potato Seeds Made Without Soil With Little Help From Peru

Parveen Arora

Potato Technology Centre, (PTC) Shamgarh, in the district in collaboration with Central Potato Research Institute (CPRI) in Shimla and International Potato Centre (CIP), Peru, has started producing potato seeds in the air with the help of aeroponic technique.

In this technique, there is no need for soil and other growing media like coco-peat for production. The scientists say that in aeroponics technique, potato seeds are grown in mist environment. They claim potato seeds grown through this technology are free from soil-borne diseases.

“We have started the process of growing minituber (potato seed) plants with the help of aeroponic technique. It is the latest technique for growing plants and potato seed production in an air or mist environment. There is no need for soil and this technology is free from soil-borne diseases,” said Dr Prem Chand Sindhu, Deputy Director, PTC, Shamgarh.

He maintained that they have established three units which have the capacity to grow 10 lakh minitubers in one crop cycle which is for three months. The scientists claimed that the production of seeds through this technique is much higher than conventional methods.

Dr Manish Sainger, the senior consultant at PTC, said that on an average, 30 minitubers and maximum 50-60 minitubers can be obtained from each plant. He said that through this technique, 7-10 times more minitubers can be obtained in comparison to conventional methods like net-house or open field.

About the technology, Dr Sainger said they planted tissue culture plants in the grow chambers which have pipes and nozzles for mist spray on the roots of the plant. “The roots of the plant hang in the air in the chamber and all the nutrients are provided through the mist, which consists of all the required elements for plant growth and tuberisation, periodically. The upper part of plant remains at the top of the chamber,” he added. He said that the size of minitubers is uniform at 3-4 gm.

Dr Sainger said it is easy to transport minitubers at minimal cost. “These seeds will be given to growers at subsidised rates by the Department of Horticulture. Later, seed growers will cultivate these seeds in the soil for the multiplication of seeds.”

Signify’s Expanded GrowWise Control System Helps Growers Boost Operational Efficiencies

Signify has expanded its GrowWise Control System, allowing for higher levels of automation and reducing manual labor and operational costs. This can be achieved by automating the lighting planning for their crop’s full growth cycle, up to one year ahead. The software tool brings dynamic lighting to greenhouses and vertical farms and fits seamlessly with modern climate computers and greenhouse management systems. This enables growers to automatically adjust light levels to maintain consistent levels on cloudy days, save energy on sunny days and simulate sunrise and sunset throughout the day or season.

 Growers, like the Italian vertical farm, Planet Farms, and the Belgium greenhouse, De Glastuin, are already using the expanded system providing additional value within their growing facility. 

“Using the GrowWise Control System is ideal for us,” says Luca Travaglini, co-founder of Planet Farms. “We want to automate as many aspects of our operations as possible to become more cost efficient. Now we can easily create custom light recipes and set them to run year-round to provide the right light recipe with the right light intensity at the right time throughout the crop’s growth cycle. By automating our full light strategy during the growth cycle, for the whole year, we can run our operations very efficiently and keep our manual labor costs low. That makes it easier for us to maintain consistent quality as we scale up our production.”

 The demand for the GrowWise Control System is increasing for greenhouse applications as well. “The lighting can be used much more efficient, since it gives us the flexibility to reduce light levels at any moment we need to,” says Wouter de Bruyn, owner at De Glastuin. Lettuce grower De Glastuin is using the GrowWise Control System to control the Philips GreenPower LED toplighting compact grow lights via its climate control system. “The climate computer is equipped with a daylight sensor that sends actual light measurements to the GrowWise Control System so we can adapt our light levels automatically to ensure an even light level throughout the day and season. This results in a continuous high-quality crop. In case the electricity is the limiting factor, we are still able to use the LEDs evenly for the whole greenhouse in a lesser intensity.”

 “Dynamic lighting in a greenhouse is the next step in improving the cost-efficiency and quality for the cultivation process,” says Udo van Slooten, Business leader Horticulture LED solutions at Signify. “It allows growers to effortlessly maintain a consistent level of light throughout the day to produce the best possible crops. The system compensates for cloudy weather and creates a more controlled growing environment for your crop.”

IPO Planned To Improve Revenues Indoors

8-01-2021| Business Live

“We believe that there is no better time to be involved in both agritech and medtech." A company which makes technology to improve indoor crop yields has received a £1 million investment ahead of a planned IPO.

Light Science Technologies has gained the funding from Intuitive Investments Group plc (IIG), ahead of going public on the London Stock Exchange in the next six months.

The business, based on the Hilton Business Park, Derby, provides lighting and plant growing and monitoring technology for agriculture in partnership with university research teams.

Its agricultural tech can be used in three main indoor settings – vertical farming (where crops such as tomatoes are grown in vertically stacked layers), greenhouses and medicinal plants.

Its patent-pending, sustainable light unit combines interchangeable LEDs, power and technology to help reduce costs and generate maximum yields over 25 years.

Its real-time monitoring and control technology can also be used to link technicians, farmers, and facility managers with their crops to provide instant production data.

Management said that with better light quality and energy savings, its light, science and technology products increase cycles.

It also supplies technology to clients in the electronics, audio, automotive, AI technology and pest control sectors.

The move to become a publicly listed company follows significant investment in its team and operations over the past few years which, the business said, has “brought to market a fully updateable, bespoke and intelligent lighting solution that provides optimal yield”.

The company is also due to launch its own in-house growth and laboratory service in the spring, focusing on plant growth and performance to help farmers with their crops.

Chief executive Simon Deacon said: “We believe that there is no better time to be involved in both agritech and medtech as two rapidly expanding sectors which are going to be responsible for spearheading some of the most significant global developments over the coming decade and beyond.

“IIG’s investment is not just a reflection of its commitment to LSTH as a fast-growing business backed by almost 30 years’ expertise in light technology but also of its awareness of the importance in achieving a better, more sustainable approach to agricultural production as well as pioneering potential life-saving solutions in digital health innovation.”

Light Science Technologies is IIG’s first investment following its own successful IPO and admission to AIM in December, as it seeks to attract investors with its life sciences portfolio.

IIG chairman David Evans said: “LSTH has the key ingredients for success; it has an excellent management team, a deep knowledge of the light spectrum and the application of that knowledge to areas where substantial growth can be obtained.

“I am personally excited about the potential diagnostic applications in the digital health sector, such as non-invasive haemoglobin measurement, as well as the developments in vertical farming technology that will underpin the long-term growth of LSTH.”

The investment follows recent funding for Light Science Technologies from Innovate UK which will see it work over the next six months with Nottingham Trent University to develop a growing sensor and transmission node for vertical farms.

“Sharing Technology Is The Only Way The Industry Will Grow”

“There is a lack of know-how amongst farmers to apply those techniques in a successful way,” says Joe Swartz, Vice president and Lead horticulturalists at AmHydro. In every situation, according to Joe, from geography to the skill of the grower or climate control, all play into what types of technology should be used. This requires a lot of experience and knowledge. Lack of this might lead to farmers being susceptible to misleading information, using ineffective technologies, which I’ve seen many people suffering from.

Joe adds, “Watching many good growers that have been led down a bad path in the industry, while investing so much into technologies that are not really effective, really breaks my heart. While providers know that they aren’t effective in this particular situation. With many years of industry experience, Joe is well aware of the challenges that the industry faces these days. Within the aquaponics sector there is not one singular technology, just as in conventional farming, rather various unique technologies can be combined for different outcomes.

Lack of know-how
When asked about the kind of growers that Joe educates, he notes that there are two kinds of growers contacting him. “We have two types of growers: either growers facing challenges or new growers wanting equipment and knowledge. Both of those approaches are interesting and it’s great to be able to help them become successful. It is great to see our system helping companies to grow and develop and become a worldwide provider. Growers like that keep coming back to us. They are the ones that move the industry”.  

Joe Swartz, Vice president 

An essential part of being a vertical farmer, in Joe’s opinion, is having experience with working on the ground floor. Only this will teach you what it takes to manage the equipment, crops and technology. “The best growers have started in the greenhouse. Hydro-experts will get nowhere with their college degree alone,” Joe states. For that reason, AmHydro offers grower seminars and even possesses a commercial greenhouse where growers can work in order to gain experience. “Some growers don’t think that they need it as they rely on technology, but my experience is exactly the opposite.”

Fake promises 
Joe observes similar trends as in the 1980s when certain technologies were promoted as ‘the farming of the future’. People talked about automatic farming, in which no farmer would be needed, new techniques and new lightings. All things we hear today were said back then. What happened afterward, according to Joe, was that some techniques turned out disappointing. Millions of dollars invested were lost, leading to the industry losing its credibility.

“As a result, investors only valid projects that already have a positive cash flow, as they have become more cautious. Some growers struggled to get funding, even though they had a viable business model. In a certain way, negative events have closed off some appetite for investments in CEA, which is a shame. It is a good investment in general, but every time we see a less than a reputable company or a technology that fails, it holds the industry back.”

Misconception
Related to that, Joe says that vertical farming still has to overcome a somewhat negative public image. “The traditional consumer, at least in the USA, have an image of farmers working on the land using sustainable methods. Now, being a conventional farmer using hydroponics I know that it is a sustainable and safe way to produce food, but there’s a public perception of automatization, as robotic food. Some people even call it “Frankenfood”. In my opinion, the more we can promote CEA as what it is, sustainable growing techniques, people will be more accepting and investors will invest more easily”.

Joe strongly senses that the vertical farming industry needs more skilled farmers and growers to meet the demand. “A lot of my work is actually training people. We want to help especially young people, new to the industry, by giving them skills, experience and knowledge. I have been blessed to have mentors when I was young and I try my best to pass that knowledge as this will help the industry along. That’s one of the reasons why we now see some consultancy firms who see economic opportunities. Sharing technology is the only way in which the industry will grow,” says Joe.

“Despite the diversity amongst growers that I meet in over 66 countries, all growers face similar problems. Funny tech flitches, pipes that break and spray water all over the greenhouse, or water pumps that break down. It doesn’t matter whether it’s a technologically advanced greenhouse or a small low-tech one. It kind of goes across the board,” says Joe laughing.

Vertical Indoor Farms Make Sense

Leadership Strategy

Teaching and consulting in the innovation field since 1990

Nate Storey, founder of a startup in the burgeoning agtech sector, which applies high-tech solutions to agriculture and farming, is convinced that the future of vegetable production is vertical and indoor cultivation, an approach that allows crops to be grown anywhere in the world to supply local markets. His company, Plenty, has just demonstrated that about two acres laid out vertically and growing hydroponically, produces more than a conventional farm covering some 720 acres.

The company, which makes intensive use of robots and algorithms for watering and providing nutrients for fruit and vegetables, closed a $140 million funding round in October, bringing total investment to $500 million and reflecting the growing interest in this type of technology. Other companies also in the San Francisco area, such as Iron Ox Robotic Farms, also rely on robotization throughout the process, from planting to plant feeding and harvesting, and report similar yields.

High-density cultivation and control throughout the production cycle reduce the incidence of pests and diseases, along with reduced transportation costs, meaning the main expense is labor (hence the need for robotization), along with the initial installation investment and energy, which is increasingly cheaper and more efficient thanks to the development of solar energy and LED technology for lighting.

Another company, Finland’s iFarm, founded three years ago, , raised $4 million in an initial investment round in August. The company provides technology to about 50 projects in Europe and the Middle East covering a total of 11,000 square meters, and is capable of automating the care of about 120 varieties of plants, with the goal of reaching 500 by 2025 (the firm says it adds 10 new varieties each month).

Others, such as Rise Gardens, which raised $2.6 million in seed capital at the end of May, provide hardware and software kits for home hydroponics, which can be assembled in less than an hour and come in three different sizes, IKEA style, which also has a similar product. Others, such as Germany’s Infarm, offer these facilities to businesses such as stores and restaurants and have also attracted investors’ interest.

And there are many more: Eden Green, Bowery Farming, BrightFarms, Freight Farms, AeroFarms… a fast-growing sector that points to a future for vertical and indoor farming. A completely different model from that of conventional farms (which are also being heavily technologized), and that can be installed in any industrial building or even in containers (or in space, if need be), and that promises a transformation similar to that from growing crops under plastic. Will the vegetables we consume in the future come from this type of innovative farms?

Benefits of Vertical Agriculture And Hydroponics

View fullsize

View fullsize

By James Ducker, MRes

Reviewed by Emily Henderson, B.Sc.

It is estimated that 11 percent, or 1.5 billion hectares, of the world’s land is used for crop production, which represents over a third of the total land suitable for crop production. With a growing population and resource needs, the availability of arable land is going to decrease substantially. Consequently, such rapidly pressing needs should be matched by a higher rate of food production.

What alternative solutions are there and what would they provide?

Throughout modern agriculture, conventional systems use large amounts of space, freshwater, fertilizer, and pesticides to maximize yield production and crop health to ensure food security, which unsustainable when looking into a future of widespread environmental and socioeconomic change.

In response, contemporary methods need to evolve to meet the current and predicted requirements of a growing world population.

Alternative solutions include the use of structural modifications such as vertical agriculture as well as entire systems by incorporating elements such as hydroponics, aeroponic, and aquaponics.

These strategies do not require fertile land to be effective, they require less water and space compared with the conventional agricultural systems and are able to increase the yield per unit of area. Additionally, these strategies use significantly fewer agrichemicals, which are potentially harmful to humans and animals.

As such, two strategies that hold promising interests is the implementation of vertical agricultural systems as well as hydroponics.

Integrating verticality into the design of agricultural systems

Agricultural systems have typically been spread over large spans of land as far as the eye can see. The reduction in arable land as well as the increase in demand to house growing populations, however, means that such strategies need to be reconsidered.

Rather than horizontal systems, large vertical walls covered crops can be used instead. These vertical layouts can employ soil, water, or air-powered systems to manage crops, and can be contained in greenhouses, warehouses, or other such facilities.

As a result, vertical agricultural systems, also known as verticulture, can encompass varying sizes and be located within many different areas from the middle of highly urbanized cities to more suburban or rural areas. The verticality aspect can also enhance nutrient and water flow, helping to reuse costly resources in a much better way than traditional methods, as demonstrated by an Indonesian research team in a study published earlier this year.

The potential location of vertical systems means that the cost of transport is nearly nullified as consumers may access them within urban areas. Moreover, the enclosed feature of verticulture means that pests and parasites are easily controlled, reducing the use of pesticides to a minimum. Finally, the reduction in space required means that there is a significant increase in yield per area, holding extensive potential for a future world of urbanization.

Despite such benefits, several limitations persist. Specifically, it is currently difficult and expensive to construct and manage such systems, which has limited their popularity. Some additional costs are also to be considered, particularly the artificial lighting that is required to help the plants grow. However, technological advances may help reduce the economic pressure of sustaining vertical systems as well as improve the overall efficiency of implementing these systems.

The development of hydroponic strategies

The transformation of agricultural systems may also include changes in applied strategies. For instance, transitioning from primary soil-based systems may provide a range of advantages, particularly in a world undergoing considerable changes in environmental conditions.

In particular, the advent of hydroponic systems represents a strategy of soilless agriculture since it uses mineral nutrient solutions in aqueous solvents to grow crops.

By relying essentially on water and nutrients, hydroponic systems are able to reduce the requirement of space and pesticides. Crop demands for nutrients and water can be controlled precisely to optimize growth and adjust to other conditions. Additionally, hydroponics can be used with other strategies, such as verticulture, and be used to address additional non-agricultural issues in urban areas.

Indeed, not only are hydroponic systems easily manageable, but they can also help mitigate issues of sanitation and animal waste processing. For instance, a recent study by African researchers earlier this year demonstrated how treated municipal wastewater can be used to establish hydroponic systems that produce healthy and sustainable crops for consumption. Additionally, a German study from 2016 designed a double recirculating system based on fish waste as fertilizer for tomato plants, with very promising results.

Nonetheless, hydroponic systems rely heavily on water and management measures, making it an expensive solution even to this day. It is therefore difficult to implement such systems at much larger scales, particularly as water scarcity is increasingly frequent and severe in many regions around the globe. In response, the combination of hydroponics with other strategies including recirculating systems or vertical designs may hold additional potential.

Alternative strategies in an era of global environmental and socioeconomic changes

Conventional agricultural systems have considerable dependencies on space and resources. Using strategies such as vertical designs and elements including hydroponics could be sustainable alternatives as they require less water, less fertilizer, and less space. Such benefits are key to consider in a rapidly changing world, particularly in terms of saving space and energy.

Rising global temperatures and the increased frequency, as well as the severity of extreme weather events, has considerable implications for crop production around the world. Moreover, geographic regions that are predicted to undergo the most environmental changes are ones that are already under socioeconomic stress, therefore exacerbating existing disparities. In response, alternative strategies that incorporate elements of sustainability are urgently required.

However, many limitations remain when considering alternative agricultural systems. In particular, the cost-effectiveness of designing and implementing such strategies may be out of reach of many regions. In response, technological advances are expected to improve our understanding of crop management and reduce the costs of strategy implementation, which can directly help to inform sustainable strategies to increase efficiency and decrease reliance on resources.

Ultimately, strategies are likely to be used in combination to complement one another and reduce the limitations that may occur. Such a coalition of strategies holds promising potential for addressing current as well as future socioeconomic and environmental challenges, yet considerable research is still required to refine such a cause.

Factory Fresh

If agriculture is to continue to feed the world, it needs to become more like manufacturing, says Geoffrey Carr. Fortunately, that is already beginning to happen

TOM ROGERS is an almond farmer in Madera County, in California’s Central Valley. Almonds are delicious and nutritious. They are also lucrative. Californian farmers, who between them grow 80% of the world’s supply of these nuts, earn $11 billion from doing so. But almonds are thirsty. A calculation by a pair of Dutch researchers six years ago suggested that growing a single one of them consumes around a gallon of water. This is merely an American gallon of 3.8 litres, not an imperial one of 4.5 litres, but it is still a tidy amount of H2O. And water has to be paid for.

Technology, however, has come to Mr. Rogers’s aid. His farm is wired up like a lab rat. Or, to be more accurate, it is wirelessed up. Moisture sensors planted throughout the nut groves keep track of what is going on in the soil. They send their results to a computer in the cloud (the network of servers that does an increasing amount of the world’s heavy-duty computing) to be crunched. The results are passed back to the farm’s irrigation system—a grid of drip tapes (hoses with holes punched in them) that are filled by pumps.

The system resembles the hydroponics used to grow vegetables in greenhouses. Every half-hour a carefully calibrated pulse of water based on the cloud’s calculations, and mixed with an appropriate dose of fertilizer if scheduled, is pushed through the tapes, delivering a precise sprinkling to each tree. The pulses alternate between one side of the tree trunk and the other, which experience has shown encourages water uptake. Before this system was in place, Mr. Rogers would have irrigated his farm about once a week. With the new little-but-often technique, he uses 20% less water than he used to. That both saves money and brings kudos, for California has suffered a four-year-long drought and there is social and political, as well as financial, pressure to conserve water.

Mr. Rogers’s farm, and similar ones that grow other high-value but thirsty crops like pistachios, walnuts, and grapes, are at the leading edge of this type of precision agriculture, known as “smart farming”. But it is not only fruit and nut farmers who benefit from being precise. So-called row crops—the maize and soyabeans that cover much of America’s Midwest—are being teched up, too. Sowing, watering, fertilizing and harvesting are all computer-controlled. Even the soil they grow in is monitored to within an inch of its life.

People will want to eat better than they do now

Farms, then, are becoming more like factories: tightly controlled operations for turning out reliable products, immune as far as possible from the vagaries of nature. Thanks to better understanding of DNA, the plants and animals raised on a farm are also tightly controlled. Precise genetic manipulation, known as “genome editing”, makes it possible to change a crop or stock animal’s genome down to the level of a single genetic “letter”. This technology, it is hoped, will be more acceptable to consumers than the shifting of whole genes between species that underpinned early genetic engineering, because it simply imitates the process of mutation on which crop breeding has always depended, but in a far more controllable way.

Understanding a crop’s DNA sequence also means that breeding itself can be made more precise. You do not need to grow a plant to maturity to find out whether it will have the characteristics you want. A quick look at its genome beforehand will tell you.

Such technological changes, in hardware, software, and “liveware”, are reaching beyond field, orchard, and byre. Fish farming will also get a boost from them. And indoor horticulture, already the most controlled and precise type of agriculture, is about to become yet more so.

In the short run, these improvements will boost farmers’ profits, by cutting costs and increasing yields, and should also benefit consumers (meaning everyone who eats food) in the form of lower prices. In the longer run, though, they may help provide the answer to an increasingly urgent question: how can the world be fed in future without putting irreparable strain on the Earth’s soils and oceans? Between now and 2050 the planet’s population is likely to rise to 9.7 billion, from 7.3 billion now. Those people will not only need to eat, they will want to eat better than people do now, because by then most are likely to have middling incomes, and many will be well off.

The Food and Agriculture Organisation, the United Nations’ agency charged with thinking about such matters, published a report in 2009 which suggested that by 2050 agricultural production will have to rise by 70% to meet projected demand. Since most land suitable for farming is already farmed, this growth must come from higher yields. Agriculture has undergone yield-enhancing shifts in the past, including mechanization before the second world war and the introduction of new crop varieties and agricultural chemicals in the green revolution of the 1950s and 1960s. Yet yields of important crops such as rice and wheat have now stopped rising in some intensively farmed parts of the world, a phenomenon called yield plateauing. The spread of existing best practice can no doubt bring yields elsewhere up to these plateaus. But to go beyond them will require improved technology.

This will be a challenge. Farmers are famously and sensibly skeptical of change since the cost of getting things wrong (messing up an entire season’s harvest) is so high. Yet if precision farming and genomics play out as many hope they will, another such change is in the offing.

Smart farms: Silicon Valley meets Central Valley

In various guises, information technology is taking over agriculture

ONE way to view farming is as a branch of matrix algebra. A farmer must constantly juggle a set of variables, such as the weather, his soil’s moisture levels and nutrient content, competition to his crops from weeds, threats to their health from pests and diseases, and the costs of taking action to deal with these things. If he does the algebra correctly, or if it is done on his behalf, he will optimize his yield and maximize his profit.

The job of smart farming, then, is twofold. One is to measure the variables going into the matrix as accurately as is cost-effective. The other is to relieve the farmer of as much of the burden of processing the matrix as he is comfortable with ceding to a machine.

An early example of cost-effective precision in farming was the decision made in 2001 by John Deere, the world’s largest manufacturer of agricultural equipment, to fit its tractors and other mobile machines with global-positioning-system (GPS) sensors, so that they could be located to within a few centimeters anywhere on Earth. This made it possible to stop them either covering the same ground twice or missing out patches as they shuttled up and down fields, which had been a frequent problem. Dealing with this both reduced fuel bills (by as much as 40% in some cases) and improved the uniformity and effectiveness of things like fertilizer, herbicide and pesticide spraying.

Bugs in the system

Bacteria and fungi can help crops and soil

MICROBES, though they have a bad press as agents of disease, also play a beneficial role in agriculture. For example, they fix nitrogen from the air into soluble nitrates that act as natural fertiliser. Understanding and exploiting such organisms for farming is a rapidly developing part of agricultural biotechnology.

At the moment, the lead is being taken by a collaboration between Monsanto and Novozymes, a Danish firm.

This consortium, called BioAg, began in 2013 and has a dozen microbe-based products on the market. These include fungicides, insecticides and bugs that liberate nitrogen, phosphorous and potassium compounds from the soil, making them soluble and thus easier for crops to take up. Last year, researchers at the two firms tested a further 2,000 microbes, looking for species that would increase maize and soyabean yields. The top-performing strains delivered a boost of about 3% for both crops.

In November 2015 Syngenta and DSM, a Dutch company, formed a similar partnership. And earlier that year, in April, DuPont bought Taxon Biosciences, a Californian microbes firm. And hopeful start-ups abound. One such is Indigo, in Boston. Its researchers are conducting field tests of some of its library of 40,000 microbes to see if they can alleviate the stress on cotton, maize, soyabeans and wheat induced by drought and salinity. Another is Adaptive Symbiotic Technologies, of Seattle. The scientists who formed this firm study fungi that live symbiotically within plants. They believe they have found one, whose natural partner is panic grass, a coastal species, which confers salinity-resistance when transferred to crops such as rice.

The big prize, however, would be to persuade the roots of crops such as wheat to form partnerships with nitrogen-fixing soil bacteria. These would be similar to the natural partnerships formed with nitrogen-fixing bacteria by legumes such as soyabeans. In legumes, the plants’ roots grow special nodules that become homes for the bacteria in question. If wheat rhizomes could be persuaded, by genomic breeding or genome editing, to behave likewise, everyone except fertilizer companies would reap enormous benefits.

Since then, other techniques have been added. High-density soil sampling, carried out every few years to track properties such as mineral content and porosity, can predict the fertility of different parts of a field. Accurate contour mapping helps indicate how water moves around. And detectors planted in the soil can monitor moisture levels at multiple depths. Some detectors are also able to indicate nutrient content and how it changes in response to the application of fertilizer.

All of this permits variable-rate seeding, meaning the density of plants grown can be tailored to local conditions. And that density itself is under precise control. John Deere’s equipment can plant individual seeds to within an accuracy of 3cm. Moreover, when a crop is harvested, the rate at which grains or beans flow into the harvester’s tank can be measured from moment to moment. That information, when combined with GPS data, creates a yield map that shows which bits of land were more or less productive—and thus how accurate the soil and sensor-based predictions were. This information can then be fed into the following season’s planting pattern.

Farmers also gather information by flying planes over their land. Airborne instruments are able to measure the amount of plant cover and to distinguish between crops and weeds. Using a technique called multispectral analysis, which looks at how strongly plants absorb or reflect different wavelengths of sunlight, they can discover which crops are flourishing and which not.

Sensors attached to moving machinery can even take measurements on the run. For example, multispectral sensors mounted on a tractor’s spraying booms can estimate the nitrogen needs of crops about to be sprayed and adjust the dose accordingly. A modern farm, then, produces data aplenty. But they need interpreting, and for that, information technology is essential.

Platform tickets

Over the past few decades, large corporations have grown up to supply the needs of commercial farming, especially in the Americas and Europe. Some are equipment-makers, such as John Deere. Others sell seeds or agricultural chemicals. These look like getting larger still. Dow and DuPont, two American giants, are planning to merge. Monsanto, another big American firm, is the subject of a takeover bid by Bayer, a German one. And Syngenta, a Swiss company, is being bid for by ChemChina, a Chinese one.

Business models are changing, too. These firms, no longer content merely to sell machinery, seed or chemicals, are all trying to develop matrix-crunching software platforms that will act as farm-management systems. These proprietary platforms will collect data from individual farms and process them in the cloud, allowing for the farm’s history, the known behavior of individual crops strains, and the local weather forecast. They will then make recommendations to the farmer, perhaps pointing him towards some of the firm’s other products.

But whereas making machinery, breeding new crops, or manufacturing agrochemicals all have high barriers to entry, a data-based farm-management system can be put together by any businessman, even without a track record in agriculture. And many are having a go. For example, Trimble Navigation, based in Sunnyvale, at the southern end of Silicon Valley, reckons that as an established geographical-information company it is well placed to move into the smart-farming market, with a system called Connected Farms. It has bought in outside expertise in the shape of AGRI-TREND, a Canadian agricultural consultancy, which it acquired last year.

By contrast, Farmobile of Overland Park, Kansas, is a startup. It is aimed at those who value privacy, making a feature of not using clients’ data to sell other products, as many farm-management systems do. Farmers Business Network, of Davenport, Iowa, uses almost the opposite model, acting as a co-operative data pool. Data in the pool are anonymized, but everyone who joins is encouraged to add to the pool, and in turn, gets to share what is there. The idea is that all participants will benefit from better solutions to the matrix.

Some firms focus on market niches. iTK, based in Montpellier, France, for example, specialises in grapes and has built mathematical models that describe the behaviour of all the main varieties. It is now expanding into California.

Thanks to this proliferation of farm-management software, it is possible to put more and more data to good use if the sensors are available to provide them. And better, cheaper sensors, too, are on their way. Moisture sensors, for example, usually work by measuring either the conductivity or the capacitance of soil, but a firm called WaterBit, based in Santa Clara, California, is using a different technology which it says can do the job at a tenth of the price of the existing products. And a sensor sold by John Deere can spectroscopically measure the nitrogen, phosphorous and potassium composition of liquid manure as it is being sprayed, permitting the spray rate to be adjusted in real time. This gets round the problem that liquid manure, though a good fertiliser, is not standardised, so is more difficult than commercial fertiliser to apply in the right quantities.

Things are changing in the air, too. In a recapitulation of the early days of manned flight, the makers of unmanned agricultural drones are testing a wide range of designs to find out which is best suited to the task of flying multispectral cameras over farms. Some firms, such as Agribotix in Boulder, Colorado, prefer quadcopters, a four-rotored modern design that has become the industry standard for small drones, though it has limited range and endurance. A popular alternative, the AgDrone, built by HoneyComb of Wilsonville, Oregon, is a single-engine flying wing that looks as if it has escaped from a 1950s air show. Another, the Lancaster 5, from PrecisionHawk of Raleigh, North Carolina, vaguely resembles a scale model of the eponymous second-world-war bomber. And the offering by Delair-Tech, based in Toulouse, France, sports the long, narrow wings of a glider to keep it aloft for long periods.

Even an endurance drone, though, may be pushed to survey a large estate in one go. For a synoptic view of their holding, therefore, some farmers turn to satellites. Planet Labs, a firm in San Francisco, provides such a service using devices called CubeSats, measuring a few centimetres across. It keeps a fleet of about 30 of these in orbit, which it refreshes as old ones die by putting new ones into space, piggybacking on commercial launches. Thanks to modern optics, even a satellite this small can be fitted with a multispectral camera, though it has a resolution per pixel of only 3.5 metres (about ten feet). That is not bad from outer space, but not nearly as good as a drone’s camera can manage.

Satellite coverage, though, has the advantage of being both broad and frequent, whereas a drone can offer only one or the other of these qualities. Planet Lab’s constellation will be able to take a picture of a given bit of the Earth’s surface at least once a week, so that areas in trouble can be identified quickly and a more detailed examination made.

The best solution is to integrate aerial and satellite coverage. That is what Mavrx, also based in San Francisco, is trying to do. Instead of drones, it has an Uber-like arrangement with about 100 light-aircraft pilots around America. Each of the firm’s contracted planes has been fitted with a multispectral camera and stands ready to make specific sorties at Mavrx’s request. Mavrx’s cameras have a resolution of 20cm a pixel, meaning they can pretty much take in individual plants.

The firm has also outsourced its satellite photography. Its raw material is drawn from Landsat and other public satellite programmes. It also has access to these programmes’ libraries, some of which go back 30 years. It can thus check the performance of a particular field over decades, calculate how much biomass that field has supported from year to year and correlate this with records of the field’s yields in those years, showing how productive the plants there have been. Then, knowing the field’s biomass in the current season, it can predict what the yield will be. Mavrx’s method can be scaled up to cover entire regions and even countries, forecasting the size of the harvests before they are gathered. That is powerful financial and political information.

A truly automated, factory-like farm, however, would have to cut people out of the loop altogether. That means introducing robots on the ground as well as in the air, and there are plenty of hopeful agricultural-robot makers trying to do so.

At the University of Sydney, the Australian Centre for Field Robotics has developed RIPPA (Robot for Intelligent Perception and Precision Application), a four-wheeled, solar-powered device that identifies weeds in fields of vegetables and zaps them individually. At the moment it does this with precise, and precisely aimed, doses of herbicide. But it, or something similar, could instead use a beam of microwaves, or even a laser. That would allow the crops concerned to be recognised as “organic” by customers who disapprove of chemical treatments.

For the less fussy, Rowbot Systems of Minneapolis is developing a bot that can travel between rows of partly grown maize plants, allowing it to apply supplementary side dressings of fertiliser to the plants without crushing them. Indeed, it might be possible in future to match the dose to the plant in farms where individual plants’ needs have been assessed by airborne multispectral cameras.

Robots are also of interest to growers of fruit and vegetables that are currently picked by hand. Fruit-picking is a time-consuming business which, even though the pickers are not well rewarded, would be a lot faster and cheaper if it were automated. And robot pickers are starting to appear.

The SW6010, made by AGROBOT, a Spanish firm, uses a camera to recognise strawberries and work out which are ripe for the plucking. Those that are have their stems severed by blades and are caught in baskets before being passed on by a conveyor belt for packing by a human operator sitting on the robot. In the Netherlands, researchers at Wageningen University are working on a robot harvester for larger produce such as peppers.

All these devices, and others like them, still exude a whiff of the Heath Robinson. But robotics is developing rapidly, and the control systems needed to run such machines are getting better and cheaper by the day. Some think that in a decade or so many farms in rich countries will be largely robot-operated.

Yet others wonder just how far farmers will let their farms be robotised. Self-guiding agricultural machinery such as that sold by John Deere is all but robotic already. It is like an airliner, in which the pilot usually has little to do between landing and take-off because computers do the work for him. Yet Deere has no plans to hand over complete control to the cloud, because that is not what its customers want.

Tunnel vision

If total control still seems some way off in outdoor farming, it is already close for crops grown in an entirely artificial environment. In a warren of tunnels beneath Clapham, in south London, Growing Underground is doing exactly what its name suggests. It is rearing around 20 types of salad plants, intended for sale to the chefs and sandwich shops of the city, in subterranean voids that began life as second-world-war bomb shelters.

In many ways, Growing Underground’s farm resembles any other indoor hydroponic operation. But there is one big difference. A conventional greenhouse, with its glass or polycarbonate walls, is designed to admit as much sunlight as possible. Growing Underground specifically excludes it. Instead, illumination is provided by light-emitting diodes (LEDs). These, in the minimalist spirit of hydroponics, have had their spectra precisely tuned so that the light they emit is optimal for the plants’ photosynthesis.

View fullsize

As you would expect, sensors watch everything—temperature, humidity, illumination—and send the data directly to Cambridge University’s engineering department where they are crunched, along with information on the plants’ growth, to work out the best regimes for future crops.

For now Steven Dring, Growing Underground’s boss, is confining output to herbs and vegetables such as small lettuces and samphire that can be brought to harvestable size quickly. He has reduced the cycle for coriander from 21 to 14 days. But tests suggest that the system also works for other, chunkier crops. Carrots and radishes have already been successfully grown this way, though they may not command a sufficient premium to make their underground cultivation worthwhile. But pak choi, a Chinese vegetable popular with trendy urbanites who live in inner-London suburbs like Clapham, is also amenable. At the moment growing it takes five weeks from start to finish. Get that down to three, which Mr Dring thinks he can, and it would be profitable.

The firms that make the LEDs could also be on to a good thing. Mr Dring’s come from Valoya, a Finnish firm. In Sweden, Heliospectra is in the same business. Philips, a Dutch electrical giant, has also joined in. In conventional greenhouses such lights are used to supplement the sun, but increasingly they do duty in windowless operations like Mr Dring’s. Though unlike sunlight they do not come free, they are so efficient and long-lasting that their spectral advantages seem clinching (see chart).

This kind of farming does not have to take place underground. Operations like Mr Dring’s are cropping up in buildings on the surface as well. Old meatpacking plants, factories and warehouses the world over are being turned into “vertical farms”. Though they are never going to fill the whole world’s bellies, they are more than a fad. Rather, they are a modern version of the market gardens that once flourished on the edge of cities —in places just like Clapham—before the land they occupied was swallowed by urban sprawl. And with their precise control of inputs, and thus outputs (see Brain scan, below), they also represent the ultimate in what farming could become.

Brain scan: Caleb Harper

PLANT breeders are understandably excited about manipulating botanical genomics (see next page). But it is a crop’s phenotype—its physical instantiation—that people actually eat, and this is the product of both genes and environment.

Optimising phenotypes by manipulating the environment is the task Caleb Harper has set himself. Dr Harper is the founder of the Open Agriculture Initiative (OAI) at the Massachusetts Institute of Technology’s Media Lab. At first sight, that seems odd. The Media Lab is an information-technology laboratory, best known for having helped develop things like electronic paper, wireless networks and even modern karaoke machines. It is very much about bits and bytes, and not much hitherto about proteins and lipids.

However, environmental information is still information. It informs how a plant grows, which is what interests Dr Harper. As he once put it, “people say they like peppers from Mexico. What they actually like is peppers grown in the conditions that prevail in Mexico.” He reckons that if you can replicate the conditions in which a botanical product grew, you can replicate that product. But this means you have to understand those conditions properly in the first place.

To help with this, he and his colleagues at the OAI have developed what they call the Personal Food Computer: a standardised tabletop device that can control illumination, carbon-dioxide levels, humidity, air temperature, root-zone temperature, and the acidity and dissolved-oxygen content of water delivered to the roots, as well as its nutrient content and any other aspect of its chemistry.

Plant phenotypes are monitored during growth by web cameras linked to software that detects leaf edges and colour differences and by sensors that can detect areas of active photosynthesis. After harvesting they are examined by lidar (the optical equivalent of radar) to record their shape in detail, and by gas chromatography/mass spectroscopy to understand their chemical composition.

The idea is that Personal Food Computers can be built by anyone who chooses to, and form part of an “open science” network that gathers data on growing conditions and works out those conditions’ phenotypic effects. Of particular interest are matters such as flavour and astringency that are governed by chemicals called secondary metabolites. These are often parts of plant-defence mechanisms, so in one experiment the computers are looking at the effect of adding crushed arthropod exoskeletons to the water supply, which may mimic attack by insects or mites. The hope is that this will change flavours in controllable ways.

Though Dr Harper is from a rural background, his career before the OAI was conventionally Media Lab-like. In particular, he designed environmental-control systems for data centres and operating theatres—keeping heat, humidity and so on within the tight limits needed for optimal function. But the jump from controlling those environments to controlling miniature farms was not enormous.

Some three dozen Personal Food Computers already exist and about 100 more are under construction the world over. This geographical dispersion is important. Dr. Harper’s goal, as his view on Mexican peppers suggests, is to decouple climate from geography by building a “catalogue of climates”. That would allow indoor urban farms to be programmed to imitate whatever climate was required in order to turn out crops for instant local consumption. This would certainly appeal to those who worry about “food miles”—the cost in terms of carbon dioxide of shipping edible items around the world. How it will go down with farmers in places whose climates are being imitated in rich-country cities remains to be seen.

Crops of the future: Tinker and tailor

Farms need better products. Genomic understanding will provide them

C4 SOUNDS like the name of a failed electric car from the 1970s. In fact, it is one of the most crucial concepts in plant molecular biology. Plants have inherited their photosynthetic abilities from bacteria that took up symbiotic residence in the cells of their ancestors about a billion years ago. Those bacteria’s descendants, called chloroplasts, sit inside cells absorbing sunlight and using its energy to split water into hydrogen and oxygen. The hydrogen then combines with carbon dioxide to form small intermediate molecules, which are subsequently assembled into sugars. This form of photosynthesis is known as C3, because these intermediates contain three carbon atoms. Since the arrival of chloroplasts, though, evolution has discovered another way to photosynthesise, using a four-carbon intermediate. C4 photosynthesis is often more efficient than the C3 sort, especially in tropical climes. Several important crops that started in the tropics use it, notably maize, millet, sorghum, and sugar cane.

C4 photosynthesis is so useful that it has evolved on at least 60 separate occasions. Unfortunately, none of these involved the ancestors of rice, the second most important crop on Earth, after wheat. Yet rice, pre-eminently a tropical plant, would produce yields around 50% bigger than at present if it took the C4 route. At the International Rice Research Institute in Los Banos, outside Manila, researchers are trying to show it how.

The C4 Rice Project, co-ordinated by Paul Quick, is a global endeavour, also involving biologists at 18 other laboratories in Asia, Australia, Europe and North America. Their task involves adding five alien enzymes to rice, to give it an extra biochemical pathway, and then reorganising some of the cells in the plant’s leaves to create special compartments in which carbon dioxide can be concentrated in ways the standard C3 mechanism does not require. Both of these things have frequently happened naturally in other plants, which suggests that doing them artificially is not out of the question. The team has already created strains of rice which contain genes plucked from maize plants for the extra enzymes, and are now tweaking them to improve their efficacy. The harder part, which may take another decade, will be finding out what genetic changes are needed to bring about the compartmentalisation.

Genome editing resembles the natural process of mutation

The C4 Rice Project thus aims to break through the yield plateaus and return the world to the sort of growth rates seen in the heady days of the Green Revolution. Other groups, similarly motivated, are working on making many types of crops resistant to drought, heat, cold and salt; on inducing greater immunity to infection and infestation; on improving nutritional value; on making more efficient use of resources such as water and phosphorous; and even on giving to plants that do not have it the ability to fix nitrogen, an essential ingredient of proteins, directly from the air instead of absorbing it in the form of nitrates. Such innovations should be a bonanza. Unfortunately, for reasons both technical and social, they have so far not been. But that should soon change.

The early days of genetically engineered crops saw two huge successes and one spectacular failure. The successes were the transfer into a range of plants, particularly maize, soyabeans and cotton, of two types of gene. Both came from bacteria. One protected its host from the attentions of pesky insect larvae. The other protected it from specific herbicides, meaning those herbicides could be used more effectively to keep fields free from weeds. Both are beloved of farmers.

The spectacular failure is that neither is beloved of consumers. Some are indifferent to them; many actively hostile. Even though over decades there has been no evidence that eating genetically modified crops is harmful to health, and little that they harm the environment, they have been treated as pariahs.

Since people do not eat cotton, and soyabeans and maize are used mainly as animal fodder, the anti-GM lobby’s impact on those crops has been muted. But the idea of extending either the range of crops modified or the range of modifications available has (with a few exceptions) been thought commercially too risky to try. Moreover, transgenics, as the technique of moving genes from one species to another is called, is haphazard. Where the moved gene will end up is hard to control. That matters, for genes work better in some places than others.

Spell it for me

The search has therefore been on for a better way than transgenics of doing things. And one is now emerging that, its supporters hope, may kill both the technical and the social birds with a single stone. Genome editing, as this approach is known, tweaks existing DNA in situ by adding, subtracting or substituting a piece that may be as small as a single genetic “letter” (or nucleotide). That not only makes the technique precise, it also resembles the natural process of mutation, which is the basis of the variety all conventional plant-breeding relies on. That may raise fewer objections among consumers, and also holds out the hope that regulators will treat it differently from transgenics.

After a couple of false starts, most researchers agree that a technique called CRISPR/Cas9, derived from a way that bacteria chop up the genes of invading viruses, is the one that will make editing crop genomes a realistic prospect. Transgenic technology has steered clear of wheat, which is eaten mainly by people. But DuPont’s seed division, Pioneer, is already trying to use CRISPR/Cas9 to stop wheat from self-pollinating, in order to make the development of hybrids easier. Similarly, researchers at the Chinese Academy of Sciences are using it to try to develop wheat plants that are resistant to powdery mildew, a serious hazard.

Not all current attempts at agricultural genome editing use CRISPR/Cas9. Cibus, in San Diego, for example, employs a proprietary technique it calls the Rapid Trait Development System (RTDS). This co-opts a cell’s natural DNA repair mechanism to make single-nucleotide changes to genomes. RTDS has already created one commercial product, a form of rape resistant to a class of herbicides that conventional transgenics cannot protect against. But at the moment CRISPR/Cas9 seems to be sweeping most things before it—and even if it stumbles for some reason, other bacterial antiviral mechanisms might step in.

Whether consumers will accept genome editing remains to be seen. No one, however, is likely to object to a second rapidly developing method of crop improvement: a souped-up breeding technique called genomic selection.

Genomic selection is a superior version of marker-assisted selection, a process which has itself been replacing conventional crop-breeding techniques. Both genomic selection and markerassisted selection rely on recognising pieces of DNA called markers found in or near places called quantitative trait loci (QTLs). A QTL is part of a genome that has, because of a gene or genes within it, a measurable, predictable effect on a phenotype. If the marker is present, then so is the QTL. By extension, a plant with the marker should show the QTL’s phenotypic effect.

The difference between conventional marker-assisted selection and the genomic version is that the former relied on a few hundred markers (such as places where the DNA stuttered and repeated itself) that could be picked up by the technology then available. Now, improved detection methods mean single-nucleotide polymorphisms, or SNPs (pronounced “snips”), can be used as markers. A SNP is a place where a single genetic letter varies in an otherwise unchanging part of the genome, and there are thousands of them.

Add in the enormous amounts of computing power available to link SNPs with QTLs—and, indeed, to analyse the interactions between QTLs themselves—and the upshot is a system that can tell a breeder which individual plants are worth raising to maturity, and which should then be crossed with each other to come up with the best results.

Crop strains created this way are already coming to market. AQUAmax and Artesian are drought-tolerant strains of maize developed, respectively, by DuPont and Syngenta. These two, intriguingly, are competitors with another drought-tolerant maize strain, DroughtGuard, developed by Monsanto using the transgenic approach.

Genomic selection also offers opportunities for the scientific improvement of crops that seed companies usually neglect. The NextGen Cassava Project, a pan-African group, plans to zap susceptibility to cassava mosaic virus this way and then systematically to improve the yield and nutritional properties of the crop. The project’s researchers have identified 40,000 cassava SNPs, and have now gone through three generations of genomic selection using them. Besides making cassava resistant to the virus, they also hope to double yields and to increase the proportion of starch (and thus the nutritional value) of the resulting strains. If modern techniques can similarly be brought to bear on other unimproved crops of little interest to the big seed companies, such as millet and yams, the yield-bonuses could be enormous.

For the longer term, some researchers have more radical ambitions. A manifesto published last year by Donald Ort, of the United States Department of Agriculture’s Agricultural Research Service, and his colleagues proposes not merely recapitulating evolution but actually redesigning the photosynthetic process in ways evolution has not yet discovered. Dr Ort suggests tweaking chlorophyll molecules in order to capture a wider range of frequencies and deploy the resulting energy more efficiently. He is also looking at improving the way plants absorb carbon dioxide. The result, he hopes, will be faster-growing, higher-yielding crops.

Such ideas are controversial and could take decades to come to fruition. But they are not fantastic. A combination of transgenics (importing new forms of chlorophyll from photosynthetic bacteria), genome editing (to supercharge existing plant enzymes) and genomic selection (to optimise the resulting mixture) might well be able to achieve them.

Those who see this as an unnatural, perhaps even monstrous approach to crop improvement should recall that it is precisely what happened when the ancestors of modern plants themselves came into existence, through the combination of a bacterium and its host and their subsequent mutual adjustment to live in symbiosis. It was this evolutionary leap which greened the Earth in the first place. That something similar might re-green it is at least worth considering.

Fish farming: Catch of the day

Farming marine fish inland will relieve pressure on the oceans

IN THE basement of a building on a wharf in Baltimore’s inner harbour, a group of aquaculturists at the Institute of Marine and Environmental Technology is trying to create an artificial ecosystem. Yonathan Zohar and his colleagues hope to liberate the raising of ocean fish from the ocean itself so that fish farms can be built inland. Fresh fish, served the day it comes out of the brine (even if the brine in question is a judicious mixture of tap water and salts), would thus become accessible to millions of landlubbers who must now have their fish shipped in from afar, deep-frozen. Equally important, marine-fish farmers would no longer have to find suitable coastal sites for penning stock while it grows to marketable size, exposing the crowded animals to disease and polluting the marine environment.

People have raised freshwater fish in ponds since time immemorial, but farming species such as salmon that live mainly in saltwater dates back only a few decades, as does the parallel transformation of freshwater aquaculture to operate on an industrial scale. Now fish farming is booming. As the chart on the next page shows, human consumption of farmed fish has overtaken that of beef. Indeed, one way of supplying mankind with enough animal protein in future may be through aquaculture. To keep the boom going, though, technologists like Dr Zohar must become ever more inventive.

His ecosystem, which is about to undergo commercial trials, constantly recycles the same supply of brine, purified by three sets of bacteria. One set turns ammonia excreted by the fish into nitrate ions. A second converts these ions into nitrogen (a harmless gas that makes up 78% of the air) and water. A third, working on the solid waste filtered from the water, transforms it into methane, which—via a special generator—provides part of the power that keeps the whole operation running. The upshot is a closed system that can be set up anywhere, generates no pollution and can be kept disease-free. It is also escape-proof. That means old-world species such as sea bream and sea bass, which cannot now be grown in America because they might get out and breed in the wild, could be delivered fresh to the table anywhere.

Besides transforming the design of fish farms, Dr Zohar is also working on extending the range of species that they can grow. He has spent decades studying the hormone system that triggers spawning and can now stimulate it on demand. He has also examined the needs of hatchling fry, often completely different from those of adult fish, that must be met if they are to thrive. At the moment he is trying to do this for one of the most desirable species of all, the bluefin tuna. If he succeeds, and thus provides an alternative to the plummeting wild populations of this animal, sushi lovers around the world will be for ever in his debt.

Gone fishin’

Fish farmers used to dream of fitting their charges with transgenes to make them grow more quickly. Indeed, over the past couple of decades researchers have treated more than 35 fish species in this way. They have often been spectacularly successful. Only one firm, though, has persisted to the point of regulatory approval. AquaBounty’s transgenic Atlantic salmon, now cleared in both America and Canada, has the desirable property of rapid growth. Its transgene, taken from a chinook salmon, causes it to put on weight all year round, not just in spring and summer. That halves the time the fish will take to reach marketable size. Whether people will be willing to eat the result, though, is an experiment in its own right—one that all those other researchers, only too aware of widespread public rejection of transgenic crops, have been unwilling to conduct.

That may be wise. There is so much natural variation in wild fish that conventional selective breeding can make a big difference without any high-tech intervention. Back in 2007 a report by researchers at Akvaforsk, now part of the Norwegian Institute of Food, Fisheries and Aquaculture Research (NOFIMA), showed that three decades of selective breeding by the country’s salmon farmers had resulted in fish which grew twice as fast as their wild progenitors. Admittedly starting from a lower base, those farmers had done what AquaBounty has achieved, but without the aid of a transgene.

If conventional selection can yield such improvements, it is tempting not to bother with anything more complicated. Tempting, but wrong. For, as understanding of piscine DNA improves, the sort of genomic selection being applied to crops can also be applied to fish.

Researchers at SalmoBreed of Bergen, in Norway, have employed it not to create bigger, faster-growing fish but to attack two of fish farming’s banes—infestation and infection. By tracking SNPs (single-nucleotide polymorphisms, a variation of a single genetic letter in a genome used as a marker) they have produced varieties of salmon resistant to sea lice and also to pancreas disease, a viral illness. They are now looking into a third problem, amoebic gill disease. In Japan, similar work has led to the development of flounders resistant to viral lymphocystis, trout immune to “cold-water” disease, a bacterial infection, and amberjack that evade the attentions of a group of parasitic worms called the monogenea.

Altering nature, then, is crucial to the success of fish farming. But nurture can also give a helping hand, for example by optimising what is fed to the animals. As with any product, one key to success is to get costs down. And here, environmental and commercial considerations coincide.

A common complaint by green types is that fish farming does not relieve as much pressure on the oceans as it appears to, because a lot of the feed it uses is made of fish meal. That simply transfers fishing pressure from species eaten by people directly to those that get turned into such meal. But fish meal is expensive, so researchers are trying to reduce the amount being used by substituting plant matter, such as soya. In this they have been successful. According to a paper published last year by researchers at NOFIMA, 90% of salmon feed used in Norway in 1990 was fish meal. In 2013 the comparable figure was 30%. Indeed, a report published in 2014 by the European Parliament found that fish-meal consumption in aquaculture peaked in 2005.

It’s a gas

Feeding carnivores like salmon on plants is one way to reduce both costs and environmental harm. Another, which at first sight seems exotic, is to make fish food out of natural gas. This is the proposed business of Calysta, a Californian firm. Calysta feeds the gas—or, rather, its principal component, methane—to bacteria called methanotrophs. These metabolise the methane, extract energy from it and use the atoms thus liberated, along with oxygen from water and nitrogen from the air, to build their bodies. Calysta then turns these bodies into protein pellets that are sold as fish food, a process that puts no strain at all on either sea or field.

Even conventional fish foods, though, are low-strain compared with feed for farm animals. Because fish are cold-blooded, they do not have to eat to stay warm. They thus convert more of their food into body mass. For conservationists, and for those who worry whether there will be enough food in future to feed the growing human population, that makes fish a particularly attractive form of animal protein.

Nevertheless, demand for the legged and winged sort is growing too. Novel technologies are therefore being applied to animal husbandry as well. And some imaginative researchers are even trying to grow meat and other animal products in factories, cutting the animals out of the loop altogether.

Animal husbandry: Stock answers

Technology can improve not only productivity but animal welfare too

IF THE future of farming is to be more factory-like, some might argue that the treatment of stock animals such as chickens and pigs has led the way. Those are not, though, happy precedents. Crop plants, unsentient as they are, cause no welfare qualms in those who worry about other aspects of modern farming. Even fish, as long as they are kept healthy, rarely raise the ire of protesters. Birds and mammals are different. There are moral limits to how they can be treated. They are also individually valuable in a way that crop plants and fish are not. For both these reasons, they are worth monitoring one at a time.

Cattle, in particular, are getting their own private sensors. Devices that sit inside an animal’s rumen, measuring stomach acidity and looking for digestive problems, have been available for several years. They have now been joined by movement detectors such as that developed by Smartbell, a small firm in Cambridge, England. This sensor hangs around a cow’s neck, recording its wearer’s movement and transmitting that information to the cloud. An animal’s general activity level is a good indication of its fitness, so the system can give early warning of any trouble. In particular, it immediately shows when its wearer is going lame—a problem that about a fifth of British cattle suffer at some point in their lives—even before an observant farmer might notice anything wrong. If picked up early, lameness is easily treated. If permitted to linger, it often means the animal has to be destroyed.

Movement detectors can also show if a cow is ready for insemination. When she is in oestrus, her pattern of movement changes, and the detector will pick this up and alert her owner. Good breeding is crucial to animal husbandry, and marker-assisted genomic selection will ensure that the semen used for such insemination continues to yield better and better offspring. What is less clear—and is actively debated—is whether genome editing has a role to play here. Transgenics has given an even wider berth to terrestrial animals than it has to fish, and for the same reason: wary consumers. Some people hope, though, that this wariness will not apply to animals whose DNA has merely been tweaked, rather than imported from another species, especially if the edits in question will improve animal welfare as well as farmers’ profits.

Following this line of thinking, Recombinetics, a firm in St Paul, Minnesota, is trying to use genome editing of the sort now being employed on crops to create a strain of hornless Holstein cattle. Holsteins are a popular breed for milking, but their horns make them dangerous to work with, so they are normally dehorned as calves, which is messy, and painful for the animal. Scott Fahrenkrug, Recombinetics’ founder, therefore had the idea of introducing into Holsteins a DNA sequence that makes certain beef cattle hornless. This involved deleting a sequence of ten nucleotides and replacing it with 212 others.

Bruce Whitelaw at the Roslin Institute, in Scotland, has similarly edited resistance to African swine fever into pigs, by altering a gene that helps regulate immune responses to this illness to make it resemble the version found in warthogs. These wild African pigs have co-evolved with the virus and are thus less susceptible to it than are non-African domesticated animals. Randall Prather at the University of Missouri has similarly created pigs that cannot catch porcine reproductive and respiratory syndrome, an illness that costs American farmers alone more than $600m a year. And at the International Livestock Research Institute in Nairobi, Steve Kemp and his colleagues are considering editing resistance to sleeping sickness, a huge killer of livestock, into African cattle. All this would make the animals healthier and hence happier as well.

Not all such work is welfare-oriented, though. Dr Fahrenkrug has also been working on a famous mutation that increases muscle mass. This mutation, in the gene for a protein called myostatin, is found naturally in Belgian Blue cattle. Myostatin inhibits the development of muscle cells. The Belgian-Blue mutation disrupts myostatin’s structure, and thus function. Hence the animals’ oversize muscles. Two years ago, in collaboration with researchers at Texas A&M University, Dr Fahrenkrug edited the myostatin gene of a member of another breed of cattle to do likewise.

Where’s the beef?

There may, though, be an even better way to grow muscle, the animal tissue most wanted by consumers, than on animals themselves. At least two groups of researchers think it can be manufactured directly. In 2013 Mark Post of Maastricht University, in the Netherlands, unveiled the first hamburger made from muscle cells grown in laboratory cultures. In February this year a Californian firm called Memphis Meats followed suit with the first meatball.

Dr Post’s original hamburger, which weighed 140 grams, was assembled from strips of muscle cells grown in Petri dishes. Including all the set-up costs, it was said to have cost 250,000 ($350,000), or $2.5m a kilogram. Scaling up the process will bring that figure down a lot. This means growing the cells in reactor vessels filled with nutrient broth. But, because such cells are supposed to be parts of bodies, they cannot simply float around in the broth in the way that, for example, yeast cells used in biotechnology can. To thrive, they must be attached to something, so the idea is to grow them on small spheres floating in the vessels. Fat cells, which add juiciness to meat, would be cultured separately.

Do this successfully, Dr Post reckons, and the cost would fall to $65 a kilogram. Add in technological improvements already under way, which will increase the density of muscle cells that can be grown in a reactor, and he hopes that Mosa Meat, the firm he has founded to exploit his work commercially, will have hamburger mince ready for sale (albeit at the pricey end of the market) in five years’ time.

Meanwhile, researchers at Clara Foods, in San Francisco, are developing synthetic egg white, using transgenic yeast to secrete the required proteins. Indeed, they hope to improve on natural egg white by tweaking the protein mix to make it easier to whip into meringues, for example. They also hope their synthetic white will be acceptable to people who do not currently eat eggs, including vegans and some vegetarians.

Towards 2050: Vorsprung durch Technik

Technology will transform farmers’ lives in both the rich and the poor world

ONE of the greatest unsung triumphs of human progress is that most people are no longer working on the land. That is not to demean farming. Rather, it is to praise the monumental productivity growth in the industry, achieved almost entirely by the application of technology in the form of farm machinery, fertilisers and other agrochemicals, along with scientifically improved crops and livestock. In 1900 around 41% of America’s labour force worked on a farm; now the proportion is below 2%. The effect is less marked in poorer countries, but the direction of travel is the same. The share of city-dwellers in the world’s total population reached 50% in 2007 and is still rising relentlessly, yet the shrinking proportion of people living in the countryside is still able to feed the urban majority.

No crystal ball can predict whether that will continue, but on past form it seems perfectly plausible that by 2050 the planet will grow 70% more food than it did in 2009, as the Food and Agriculture Organisation (FAO) says it needs to. Even though some crops in some parts of the world have reached a productivity plateau, cereal production increased by 11% in the six years after the FAO made that prediction. The Malthusian fear that population growth will outstrip food supply, now 218 years old, has not yet come true.

Yet just as Thomas Malthus has his modern-day apologists, so does his mythical contemporary, Ned Ludd. Neo-Luddism is an ever-present threat that can certainly slow down the development of new technologies—as has indeed happened with transgenics. But while it is fine for the well-fed to be prissy about not eating food containing genetically modified ingredients, their fears have cast a shadow over the development of transgenic crops that might help those whose bellies are not so full. That is unconscionable. With luck, the new generation of genome-edited plants, and maybe even animals, will not provoke such a reaction.

Regardless of whether it does, though, some other trends seem near-certain to continue into the future. Precision agriculture will spread from its North American heartland to become routine in Europe and those parts of South America, such as Brazil, where large arable farms predominate. And someone, perhaps in China, will work out how to apply to rice the sort of precision techniques now applied to soyabeans, maize and other crops.

The technological rationale for precision suggests farms should continue to consolidate, though in an industry in which sentiment and family continuity have always played a big part that purely economic analysis might suggest is irrational, this may not happen as fast as it otherwise would. Still, regardless of the speed at which they arrive, these large holdings will come more and more to resemble manufacturing operations, wringing every last ounce of efficiency out of land and machinery.

Such large-scale farms will probably continue to be served by large-scale corporations that provide seeds, stock, machines and management plans. But, in the case of the management plans, there is an opening for new firms with better ideas to nip in and steal at least part of the market.

Other openings for entrepreneurs are available, too. Both inland fish farming and urban vertical farming—though niche operations compared with Midwestern soyabean cultivation or Scottish sea-loch salmon farms—are waves of the future in the service of gustatorially sophisticated urbanites. And in these businesses, the idea of farm as factory is brought to its logical conclusion.

It is in the poorer parts of the world, though, that the battle for full bellies will be won or lost; and in Africa, in particular, the scope for change is both enormous and unpredictable. Though the problems of African farming are by no means purely technological—better roads, better education, and better governments would all help a great deal—technology nevertheless has a big part to play. Organizations such as the NextGen Cassava Project, which apply the latest breeding techniques to reduce the susceptibility of crops to disease and increase their yield and nutritional value, offer Africans an opportunity to leap into the future in the way they did with telephony, bypassing fixed-line networks and moving straight to mobiles. Crops could similarly jump from 18th- to 21st-century levels of potential in a matter of years, even if converting that potential into productivity still requires the developments listed earlier.

Looking further into the future, the picture is hazier. Large-scale genetic engineering of the sort needed to create C4 rice, or nitrogen-fixing wheat, or enhanced photosynthetic pathways, will certainly cause qualms, and maybe not just among the neo-Luddites. And they may not be needed. It is a general technological truth that there are more ideas than applications, and perfectly decent ones fall by the wayside because others have got there first. But it is good to know that the big ideas are there, available to be drawn on in case other yield plateaus threaten the required rise in the food supply. It means that the people of 2050, whether they live in Los Angeles, Lucknow or Lusaka, will at least be able to face whatever other problems befall them on a full stomach.

Smart Acres CEO On The Latest Addition To The Hydroponic Vertical Farming Industry In Abu Dhabi

View fullsize

September 13th, 2020

Smart Acres is here with lettuce at the helm. In an exclusive interview with Abu Dhabi World, Smart Acres CEO Abdulla al Kaabi reveals what this means to Abu Dhabi and the farming community on the whole. 

If you love healthy produce, and who doesn’t, then this news is going to please you and your tastebuds no end. The only drawback at the moment is they’re not for sale in supermarkets just yet, but it won’t be long before they are.

The launch of Smart Acres, the UAE’s latest addition to the hydroponic vertical farming industry, this week means that a line of the freshest, most nutrient-dense greens for UAE residents and businesses alike is now being produced in containers on the Armed Forces Officers Club in Abu Dhabi, with the aim to expand across the UAE.

So we headed over to the St. Regis Abu Dhabi to meet Smart Acres CEO Abdulla al Kaabi to find out more.

Tell us about your background?

I am from a tech and farm background. My father has a passion for farming and gardening; he’s very  strict about anybody who messes around with his garden or farm. My father has a few farms across the UAE, where he grows crops and dates.  When he heard that I was pursuing a project in the agriculture sector he got excited and actually gifted me a farm, which I am grateful for and will keep. However, Smart Acres, rather than the farm my father gifted me, is an urban farm.

How was Smart Acres first developed?

View fullsize

CEO Abdulla al Kaabi (centre)

Smart Acres was founded in 2017 and local testing began in July 2019. Smart Acres was developed by a team of experts,  including myself, Director Sean Lee, and Lead Project Manager, Aphisith Phongsavanh with the aim of improving food security within the United Arab Emirates and developing the country’s farming capabilities, providing a solution to potential socioeconomic threats such as pandemics and climate limitations the Middle East currently endures.

Tell us more

We planted lettuce and after a few harvests, we decided to expand from two containers to eight containers. From the two insulated containers, the yield was 3.5 tons annually, which was our proof of concept. For the proof of concept, our target weight for each lettuce head was 140g. However, we have reached an average of 200g per head. I don’t think any other vertical farm here reached that quality or weight in terms of vegetables at this size.

How would you describe Smart Acres?

It is a one-of-a-kind agriculture system that is designed to produce some of the highest yields of crops within the UAE’s vertical farming industry while introducing a new future for clean foods and allowing both business to business (B2B) and business to consumer (B2C ) sectors to locally sourced produce.

Tell us about the containers

We invested heavily in the containers, not just financially, and it took us a while to partner up with n.thing, a South Korean vertical farming technology company, to bring the best vertical farm here in the UAE. We had talks with other companies before and we decided to go with this one, in terms of risk, in terms of technology they are using. And the system we are using in the containers is hydroponics (growing plants without soil)  which has been used by growers for hundreds of years. 

Techno advancements mean we were able to implement the Internet of Things for operations, which helps us to monitor the entire farm in terms of humidity, temperature, and even the nutrients that go inside the plants. Now we have our expansion plan from eight to 78 containers, which eventually will produce more than 140 tons of produce annually. We are currently in talks with private and public entities in terms of the expansion. We are also planning to have a research and development center in order to start growing our own potato seeds in a controlled environment.

Will Smart Acres just be growing lettuce?

In our current eight containers, we grow four types of lettuce;  Lolo rosso , green glace, oakleaf Batavia, but we are able to grow 30 types of lettuce.  Currently, we are testing new methods to improve the quality and weight of the existing lettuce. The results of last month’s test resulted in lettuce whose individual heads weighed more than 200 grams on average. However, we aim to grow more than just lettuce. We have plans to eventually grow baby spinach, mature spinach, and baby arugula. Smart Acres’ vision is to expand to meet the demand of popular produce in the region such as strawberries,  and, as I previously mentioned, a shift and emphasis on cultivating potato seeds.

Where can we buy your smart lettuces? 

We are now supplying restaurants and hotels for free to get ourselves known, and we have had great feedback from them. We have also partnered with several restaurants and cafes around the country including Inked and Fae Cafe, and have plans to have our produce in the kitchen of dozens of other F&B outlets. The recent initiative by HH Sheikh Mansour bin Zayed, Deputy Prime Minister, Minister of Presidential Affairs, and Abu Dhabi Agriculture and Food Safety Authority (ADAFSA), stating that all major grocery stores in the capital must allocate space for local produce mean we are perfectly poised to enter local supermarkets. We have had lots of offers from Abu Dhabi Holding and other government entities that are members in the food security committee to buy our whole produce. Currently, we are focused on our actual produce itself, in terms of quality, weight.

AgriTech - A Hotspot For Investments

AgriTech - The Sought After Technology Breakthrough 

In recent times, AgriTech or AgTech solutions are gaining their popularity factor because individuals and entities alike, are becoming increasingly aware of the efficiency technology adds to their daily processes, which otherwise would have been tasking to follow through with. The ‘revolutionary’ factor has been highlighted in the AgTech space and hence, it has caught the eyes of investors and big corporations.

AgTech represents that specific niche category of technology buffs that intermingle the age-old occupation of agriculture with the new age specs and wonders of technology.

The specifics of Agronomic Processes:

 The agronomic processes encompass diverse solutions in every step, ranging from the sowing of seeds to the harvesting of crops. The processes comprise of integrated resolutions to enhance efficiency within agricultural organizations, along with benefiting smallholder and marginal farmers. 

AgriTech, breaking barriers and records:

The upward curve of investments and profitability within the industry does not seem like it would dip anytime soon, with a continuous maturity, breaking barriers, and records. Since 2013, funding within the AgTech sector has increased by roughly a whopping 370%. According to an AgFunder report, specifically, startup investments bucked global venture capital markets across all sectors to $4.7 billion in 2019. The 695 deals were carried out across 940 unique investors.

COVID-19 comes into play:

Similar growth cannot be expected for the remainder of 2020, due to Coronavirus governing industries across all business streams. However, there is less chance of the investments cutting to a freefall wherein they would dip way lower than initially expected. New investment projects may be put on hold, however, ongoing funding is expected to be perennial.

Localizing our viewpoint, we notice that most of these investments are still being carried out within the United States. However, investments in India continue to rise at a rapid rate, representative of a two-way flow (up-stream as well as down-stream) of funding, again highlighting the maturity of the sector.

The reasoning:

WHY? Every action has an equal and opposite reaction. Sir Isaac Newton was well aware of the specifics of investment and the network within which it functions. Our world is at a point today, where overpopulation is a severe problem in various countries, along with the overall population set to increase by 30% over the next 35 years, according to Global-Engage.com. According to a report conducted by FAO, agricultural production will have to increase by 60-70% to feed the world population by 2050. To work towards an increase in the production of food, along with keeping a tap on the factor of ‘sustainability’, it is essential and integral to adopt smart farming and smart agricultural practices, allowing processes and outcomes to become more efficient in the long run.

The Need for Emerging Trends:

The importance of utilizing ‘big data’ and ‘predictive analytics’ to counteract the issues faced by farmers daily is now more than ever. They will allow farmers to achieve and maybe even surpass their targets for the seasons, resulting in an influx of productivity. In a survey conducted with farmers, 60% mentioned that precision farming is an influential trend to look towards for a structural and foundational change in the way daily practices take place. With the risk of climate change looming overhead at all times, it is crucial to understand the essential need to channel funds towards projects that solve difficult and foreseen problems.

The Agricultural 4.0 wave:

Today, 25-30% of all food produced is wasted, which incurs a social, economic, and environmental cost of $2.5 trillion annually. An outdated supply chain with no digital integrations or climate-smart advisory results in around 20% of the crops produced in developed countries being left in the field itself. To spark a change and make a difference, socially conscious investors who look to profitability as well, view the AgTech sector as a gold mine, essentially killing two birds with one stone.

AgriTech today is an area that is ripe for innovation with limits imposed solely due to constraints in terms of available capital. When this constraint is counteracted, creativity applied to AI and food production will be ten-fold.
