Vertical farming is the practice of producing food and medicine in vertically stacked layers, vertically inclined surfaces and/or integrated in other structures (such as in a skyscraper, used warehouse, or shipping container). The modern ideas of vertical farming use indoor farming techniques and controlled-environment agriculture (CEA) technology, where all environmental factors can be controlled. These facilities utilize artificial control of light, environmental control (humidity, temperature, gases...) and fertigation. Some vertical farms use techniques similar to greenhouses, where natural sunlight can be augmented with artificial lighting and metal reflectors.

Hydroponic systems can be lit by LEDs that mimic sunlight. Software can ensure that all the plants get the same amount of light, water and nutrients. Proper managements means that no herbicides or pesticides are required.

Types

The term "vertical farming" was coined by Gilbert Ellis Bailey in 1915 in his book Vertical Farming. His use of the term differs from the current meaning--he wrote about farming with a special interest in soil origin, its nutrient content and the view of plant life as "vertical" life forms, specifically relating to their underground root structures. Modern usage of the term "vertical farming" usually refers to growing plants in layers, whether in a multistory skyscraper, used warehouse, or shipping container.

Mixed-use skyscrapers

Mixed-use skyscrapers were proposed and built by architect Ken Yeang. Yeang proposes that instead of hermetically sealed mass-produced agriculture, plant life should be cultivated within open air, mixed-use skyscrapers for climate control and consumption. This version of vertical farming is based upon personal or community use rather than the wholesale production and distribution that aspires to feed an entire city. It thus requires less of an initial investment than Despommier's "vertical farm". However, neither Despommier nor Yeang are the conceptual originators, nor is Yeang the inventor of vertical farming in skyscrapers.

Despommier's skyscrapers

Ecologist Dickson Despommier argues that vertical farming is legitimate for environmental reasons. He claims that the cultivation of plant life within skyscrapers will require less embodied energy and produce less pollution than some methods of producing plant life on natural landscapes. He moreover claims that natural landscapes are too toxic for natural agricultural production, despite the ecological and environmental costs of extracting materials to build skyscrapers for the simple purpose of agricultural production.

Vertical farming according to Despommier thus discounts the value of natural landscape in exchange for the idea of "skyscraper as spaceship." Plant life is mass-produced within hermetically sealed, artificial environments that have little to do with the outside world. In this sense, they could be built anywhere regardless of the context. Although climate control, lighting, and other costs of maintenance have been posited as potentially stifling this concept, advocates have countered that an important feature of future vertical farms is the integration of renewable energy technology, be it solar panels, wind turbines and/or water capture systems. The vertical farm is designed to be sustainable, and to enable nearby inhabitants to work at the farm.

Despommier's concept of the vertical farm emerged in 1999 at Columbia University. It promotes the mass cultivation of plant life for commercial purposes in skyscrapers.

Stackable shipping containers

Several companies have developed stacking recycled shipping containers in urban settings. Brighterside Consulting created a complete off-grid container system. Freight Farms produces a "leafy green machine" that is a complete farm-to-table system outfitted with vertical hydroponics, LED lighting and intuitive climate controls built within a 12 m × 2.4 m shipping container. Podponics built a vertical farm in Atlanta consisting of over 100 stacked "growpods". A similar farm is under construction in Oman. TerraFarms offer a proprietary system of 40 foot shipping containers, which include computer vision integrated with an artificial neural network to monitor the plants; and are remotely monitored from California. It is claimed that the TerraFarm system "has achieved cost parity with traditional, outdoor farming" with each unit producing the equivalent of "three to five acres of farmland", using 97% less water through water recapture and harvesting the evaporated water through the air conditioning. As of December 2017 the TerraFarm system was in commercial operation. Plants can exploit light that varies in intensity through the day. Controlling light governs the growth cycle of the plant. E.g., infrared LEDs can mimic 5 minutes of sunset, stimulating some plants to begin flowering.

Technology

Lighting can be natural or via LEDs. As of 2018 commercial LEDs were about 28 per cent efficient, which is more efficient than keeps the cost of produce high and prevents vertical farms from competing in regions where cheap vegetables are abundant. However, lighting engineers at Philips have demonstrated LEDs with 68 per cent efficiency. Energy costs can be reduced because full-spectrum white light is not required. Instead, red and blue or purple light can be generated with less electricity.

History

In 1915, American geologist Gilbert Ellis Bailey used the concept of tall multi-story buildings for indoor cultivation. One of the earliest drawings of a tall building that cultivates food was published in Life Magazine in 1909. The reproduced drawings feature vertically stacked homesteads set amidst a farming landscape. This proposal can be seen in Rem Koolhaas's Delirious New York. Koolhaas wrote that this 1909 theorem is 'The Skyscraper as Utopian device for the production of unlimited numbers of virgin sites on a metropolitan location'.

Hydroponicum

Early architectural proposals that contributge to VF include Le Corbusier's Immeubles-Villas (1922) and SITE's Highrise of Homes (1972). SITE's Highrise of Homes is a near revival of the 1909 Life Magazine Theorem. Built examples of tower hydroponicums are documented in The Glass House by John Hix. Images of the vertical farms at the School of Gardeners in Langenlois, Austria, and the glass tower at the Vienna International Horticulture Exhibition (1964) show that vertical farms existed. The technological precedents that make vertical farming possible can be traced back to horticultural history through the development of greenhouse and hydroponic technology. Early hydroponicums integrated hydroponic technology into building systems. These horticultural building systems evolved from greenhouse technology. The British Interplanetary Society developed a hydroponicum for lunar conditions, while other building prototypes were developed during the early days of space exploration. The first Tower Hydroponic Units were developed in Armenia.

The Armenian tower hydroponicums are the first built examples of a vertical farm, and are documented in Sholto Douglas' Hydroponics: The Bengal System, first published in 1951 with data from the then-East Pakistan, today's Bangladesh, and the Indian state of West Bengal.

Later precursors that have been published, or built, are Ken Yeang's Bioclimatic Skyscraper (Menara Mesiniaga, built 1992); MVRDV's PigCity, 2000; MVRDV's Meta City/ Datatown (1998-2000); Pich-Aguilera's Garden Towers (2001).

Ken Yeang is perhaps the most widely known architect who has promoted the idea of the 'mixed-use' Bioclimatic Skyscraper which combines living units and food production.

Vertical farm

Dickson Despommier is a professor of environmental health sciences and microbiology. He reopened the topic of VF in 1999 with graduate students in a medical ecology class. He speculated that a 30-floor farm on one city block could provide food for 50,000 people including vegetables, fruit, eggs and meat, explaining that hydroponic crops could be grown on upper floors; while the lower floors would be suited for chickens and fish that eat plant waste.

Although much of Despommier's suggestions have been challenged from an environmental science and engineering point of view, Despommier successfully popularized his assertion that food production can be transformed. Critics claimed that the additional energy needed for artificial lighting, heating and other operations would outweigh the benefit of the building's close proximity to the areas of consumption.

Despommier originally challenged his class to feed the entire population of Manhattan (about 2,000,000 people) using only 5 hectares (13 acres) of rooftop gardens. The class calculated that rooftop gardening methods could feed only 2 percent of the population. Unsatisfied with the results, Despommier made an off-the-cuff suggestion of growing plants indoors, vertically. By 2001 the first outline of a vertical farm was introduced. In an interview Despommier described how vertical farms would function:

Architectural designs were independently produced by designers Chris Jacobs, Andrew Kranis and Gordon Graff.

Mass media attention began with an article written in New York magazine, followed by others, as well as radio and television features.

In 2011 the Plant in Chicago was building an anaerobic digester into the building. This will allow the farm to operate off the energy grid. Moreover, the anaerobic digester will be recycling waste from nearby businesses that would otherwise go into landfills.

In 2013 the Association for Vertical Farming was founded in Munich, Germany

As of 2014, Vertical Fresh Farms was operating in Buffalo, NY specializing in salad greens, herbs and sprouts. In March the world's then largest vertical farm opened in Scranton, Pennsylvania, built by Green Spirit Farms (GSF). The firm is housed in a single story building covering 3.25 hectares, with racks stacked six high to house 17 million plants. The farm was to grow 14 lettuce crops per year, as well as spinach, kale, tomatoes, peppers, basil and strawberries. Water is scavenged from the farm's atmosphere with a dehumidifier.

A 2015 study utilized inexpensive metal reflectors to supply sunlight to the plants, reducing energy costs.

Kyoto-based Nuvege (pronounced "new veggie") operates a windowless farm. Its LED lighting is tuned to service two types of chlorophyll, one preferring red light and the other blue. Nuvege produces 6 million lettuce heads a year.

The US Defense Advanced Research Projects Agency operates an 18-story project that produces genetically modified plants that make proteins useful in vaccines.

Problems

Economics

Opponents question the potential profitability of vertical farming. Its economic and environmental benefits rest partly on the concept of minimizing food miles, the distance that food travels from farm to consumer. However, a recent analysis suggests that transportation is only a minor contributor to the economic and environmental costs of supplying food to urban populations. The analysis concluded that "food miles are, at best, a marketing fad." Thus the facility would have to lower costs or charge higher prices to justify remaining in a city.

Similarly, if power needs are met by fossil fuels, the environmental effect may be a net loss; even building low-carbon capacity to power the farms may not make as much sense as simply leaving traditional farms in place, while burning less coal.

The initial building costs would exceed $100 million, for a 60 hectare vertical farm. Office occupancy costs can be high in major cities, with office space in cities such as Tokyo, Moscow, Mumbai, Dubai, Milan, Zurich, and Sao Paulo ranging from $1850 to $880 per square meter.

The developers of the TerraFarm system produced from second hand, 40 foot shipping containers claimed that their system "has achieved cost parity with traditional, outdoor farming".

Energy use

During the growing season, the sun shines on a vertical surface at an extreme angle such that much less light is available to crops than when they are planted on flat land. Therefore, supplemental light would be required. Bruce Bugbee claimed that the power demands of vertical farming would be uncompetitive with traditional farms using only natural light. Environmental writer George Monbiot calculated that the cost of providing enough supplementary light to grow the grain for a single loaf would be about $15. An article in the Economist argued that "even though crops growing in a glass skyscraper will get some natural sunlight during the day, it won't be enough" and "the cost of powering artificial lights will make indoor farming prohibitively expensive".

As "The Vertical Farm" proposes a controlled environment, heating and cooling costs will resemble those of any other tower. Plumbing and elevator systems are necessary to distribute nutrients and water. In the northern continental United States, fossil fuel heating cost can be over $200,000 per hectare.

Pollution

Depending on the method of electricity generation used, greenhouse produce can create more greenhouse gases than field produce, largely due to higher energy use per kilogram. Vertical farms require much greater energy per kilogram versus regular greenhouses, mainly through increased lighting. The amount of pollution produced is dependent on how the energy is generated.

Greenhouses commonly supplement CO2 levels to 3-4 times the atmospheric rate. This increase in CO2 increases photosynthesis rates by 50%, contributing to higher yields. Some greenhouses burn fossil fuels purely for this purpose, as other CO2 sources, such as those from furnaces, contain pollutants such as sulphur dioxide and ethylene which significantly damage plants. This means a vertical farm requires a CO2 source, most likely from combustion. Also, necessary ventilation may allow CO2 to leak into the atmosphere.

Greenhouse growers commonly exploit photoperiodism in plants to control whether the plants are in a vegetative or reproductive stage. As part of this control, the lights stay on past sunset and before sunrise or periodically throughout the night. Single story greenhouses have attracted criticism over light pollution.

Hydroponic greenhouses regularly change the water, producing water containing fertilizers and pesticides that must be disposed of. The most common method of spreading the effluent over neighbouring farmland or wetlands would be more difficult for an urban vertical farm.

As of 2012, Vertical Harvest was raising funds for an urban, small-scale vertical farm in Jackson Hole, Wyoming.

Advantages

Many of VF's potential benefits are obtained from scaling up hydroponic or aeroponic growing methods.

A 2018 study estimated that the value of four ecosystem services provided by existing vegetation in urban areas was on the order of $33 billion annually. The study's quantitative framework projected annual food production of 100-180 million tonnes, energy savings ranging from 14 to 15 billion kilowatt hours, nitrogen sequestration between 100,000 and 170,000 tonnes and stormwater runoff reductions between 45 and 57 billion cubic meters annually. Food production, nitrogen fixation, energy savings, pollination, climate regulation, soil formation and biological pest control could be worth as much as $80-160 billion annually.

Preparation for the future

It is estimated that by the year 2050, the world's population will increase by 3 billion people and close to 80% will live in urban areas. Vertical farms have the potential to reduce or eliminate the need to create additional farmland.

Increased crop production

Unlike traditional farming in non-tropical areas, indoor farming can produce crops year-round. All-season farming multiplies the productivity of the farmed surface by a factor of 4 to 6 depending on the crop. With crops such as strawberries, the factor may be as high as 30.

Furthermore, as the crops would be consumed where they are grown, long-distance transport with its accompanying time delays, should reduce spoilage, infestation and energy needs. Globally some 30% of harvested crops are wasted due to spoilage and infestation, though this number is much lower in developed nations.

Despommier suggests that dwarf versions of crops (e.g. dwarf wheat which is smaller in size but richer in nutrients), year-round crops and "stacker" plant holders are accounted for, a 30-story building with a base of a building block (2 hectares (5 acres)) would yield a yearly crop analogous to that of 1,000 hectares (2,400 acres) of traditional farming.

Weather disruption

Crops grown in traditional outdoor farming depend on supportive weather, and suffer from undesirable temperatures rain, monsoon, hailstorm, tornadoe, flooding, wildfires and drought. "Three recent floods (in 1993, 2007 and 2008) cost the United States billions of dollars in lost crops, with even more devastating losses in topsoil. Changes in rain patterns and temperature could diminish India's agricultural output by 30 percent by the end of the century."

VF productivity is mostly independent of weather, although earthquakes and tornadoes still pose threats.

Conservation

Up to 20 units of outdoor farmland per unit of VF could return to its natural state, due to VR's increased productivity.

Vertical farming would thus reduce the amount of farmland, thus saving many natural resources. Deforestation and desertification caused by agricultural encroachment on natural biomes could be avoided. Producing food indoors reduces or eliminates conventional plowing, planting, and harvesting by farm machinery, protecting soil and reducing emissions.

Mass extinction

Withdrawing human activity from large areas of the Earth's land surface may be necessary to address anthropogenic mass extinctions.

Traditional agriculture disrupts wild populations and may be unethical given a viable alternative. One study showed that wood mouse populations dropped from 25 per hectare to 5 per hectare after harvest, estimating 10 animals killed per hectare each year with conventional farming. In comparison, vertical farming would cause nominal harm to wildlife.

Human health

Traditional farming is a hazardous occupation that often affects the health of farmers. Such risks include: exposure to infectious diseases such as malaria and schistosomes, exposure to toxic pesticides and fungicides, confrontations with wildlife such as venomous snakes, and injuries that can occur when using large industrial farming equipment. VF reduces some of these risks. The modern industrial food system makes unhealthy food cheap while fresh produce is more expensive, encouraging poor eating habits. These habits lead to health problems such as obesity, heart disease and diabetes.

Poverty and culture

Food security is one of the primary factors leading to absolute poverty. Constructing farms will allow continued growth of culturally significant food items without sacrificing sustainability or basic needs, which can be significant to the recovery of a society from poverty.

Urban growth

Vertical farming, used in conjunction with other technologies and socioeconomic practices, could allow cities to expand while remaining substantially self-sufficient in food. This would allow large urban centers to grow without food constraints.

Energy sustainability

Vertical farms could exploit methane digesters to generate energy. Methane digesters could be built on site to transform the organic waste generated at the farm into biogas that is generally composed of 65% methane along with other gases. This biogas could then be burned to generate electricity for the greenhouse.

Plans

Despommier argues that the technology to construct vertical farms is available and that the system can be profitable and effective. Developers and local governments in multiple cities have expressed interest in establishing a vertical farm: Incheon (South Korea), Abu Dhabi (United Arab Emirates), Dongtan (China), New York City, Portland, Oregon, Los Angeles, Las Vegas, Seattle, Surrey, B.C., Toronto, Paris, Bangalore, Dubai, Shanghai and Beijing.

In 2009, the world's first pilot production system was installed at Paignton Zoo Environmental Park in the United Kingdom. The project showcased vertical farming and provided a physical base to conduct research into sustainable urban food production. The produce is used to feed the zoo's animals while the project enables evaluation of the systems and provides an educational resource to advocate for change in unsustainable land use practices that impact upon global biodiversity and ecosystem services,

In 2010 the Green Zionist Alliance proposed a resolution at the 36th World Zionist Congress calling on Keren Kayemet L'Yisrael (Jewish National Fund in Israel) to develop vertical farms in Israel.

In 2012 the world's first commercial vertical farm was opened in Singapore, developed by Sky Greens Farms, and is three stories high. They currently have over 100 nine meter-tall towers.

In 2013 the Association for Vertical Farming (AVF) was founded in Munich (Germany). By May 2015 the AVF had expanded with regional chapters all over Europe, Asia, USA, Canada and the United Kingdom. This organization unites growers and inventors to improve food security and sustainable development. AVF focuses on advancing vertical farming technologies, designs and businesses by hosting international info-days, workshops and summits.
