Vertical farming
It can also be subjected for further refinement until safe enough to be used as drinking water.” Today, over 70% of the liquid fresh water on Earth is used for conventional agriculture which often pollutes the water with fertilizers and pesticides. Many of these benefits are obtained from scaling up hydroponic or aeroponic growing methods.Deforestation, desertification, and other consequences of agricultural encroachment on natural biomes would be avoided. These flavenoids are what gives the food the flavors you re so fond of, particularly for more aromatic produce like tomatoes and peppers.
The idea sparked the students’ interests and gained major momentum. Furthermore, by using waste-water for irrigation, vertical farming would contribute to ameliorating problems with ocean dead zones, caused by algae blooms which are in turn enhanced by runoff fertilizers. Withdrawing human activity from large areas of the Earth s land surface may be necessary to slow and eventually halt the current anthropogenic mass extinction of land animals. Traditional agriculture is highly disruptive to wild animal populations that live in and around farmland and some argue it becomes unethical when there is a viable alternative.
Vertical farming is a proposed agricultural technique involving large-scale agriculture in urban high-rises or farmscrapers . Unsatisfied with the results, Despommier thoughtlessly suggested growing plants indoors, vertically.
Because vertical farming lets crops be grown closer to consumers, it would substantially reduce the amount of fossil fuels currently used to transport and refrigerate farm produce. Scientists are concerned that this large amount of required farmland will not be available and that severe damage to the earth will be caused by the added farmland.
In order to feed 3 billion more people using traditional farming techniques an estimated 10^9 hectares of new farmland must be created. Research has shown that 30% of harvested crops are wasted due to spoilage and infestations. Despommier suggests that, if dwarf versions of certain crops are used (e.g.
You ll even have systems to monitor plant diseases by employing DNA chip technologies that detect the presence of plant pathogens by simply sampling the air and using snippets from various viral and bacterial infections. The class calculated that, by using rooftop gardening methods, only 2 percent of the 50,000 people would be fed.
It s very easy to do. Moreover, a gas chromatograph will tell us when to pick the plant by analyzing which flavenoids the produce contains. These are all right-off-the-shelf technologies.
Methane digesters could be built on site to transform the organic waste generated at the farm into biogas which is generally composed of 65% methane along with other gasses. The most common technologies suggested are: Professor Despommier argues that the technology to construct vertical farms currently exists.
The ability to construct a vertical farm exists now. and Maxim (magazine), among others, as well as radio and television features. Several potential advantages of vertical farming have been discussed by Despommier.
This would allow for large urban centers that could grow without destroying considerably larger areas of forest to provide food for their people. Artificial lighting would be needed for crops growing in areas of the building unexposed to sunlight. The detailed analytical work needed to establish the feasibility of vertical farming has not yet been completed.
Water extracted will undergo bio-remediation processes using cattails, sawgrass and zebra mussels, until it becomes clean enough for agricultural use. Others relate to vertical farming building designs that would allow the use of renewable energy sources (wind and solar) and the recycling of materials of production such as water. It is estimated that by the year 2050, close to 80% of the world’s population will live in urban areas and the total population of the world will increase by 3 billion people.
The remaining slurry will be burned like coal to power steam turbines that will generate electricity. 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. Traditional farming is a hazardous occupation with particular risks that often take their toll on the health of human laborers.
We don t have to make anything new. Architectural designs have been produced by Chris Jacobs of United Future, Andrew Kranis at Columbia University and Gordon Graff at the University of Waterloo. Mass media attention began with an article by Lisa Chamberlain in New York magazine. Burning less fossil fuel would reduce air pollution and the carbon dioxide emissions that cause climate change, as well as create healthier environments for humans and animals alike. Furthermore, vertical farms would make maximal use of the locally most efficient sources of renewable energy: farms in Iceland, Italy and New Zealand would benefit from geothermal energy, desert environments such as in the Middle East would make use of abundant solar energy (in which case the structures would have to be wider than they are tall, to maximize solar energy input), and coastal areas would benefit from wind, wave or tidal energies. Vertical Farms would also be designed to convert waste water and polluted air into clean, useable resources for crop production.
By 2001 the first outline of a vertical farm was introduced and today scientists, architects, and investors worldwide are working together to make the concept of vertical farming a reality. He estimates that, using currently available technologies, one vertical farm occupying one square city block and rising 30 stories would feed 10,000 people. The economic and environmental benefits of vertical farming rest partly on the concept of minimizing food miles, the distance that food travels from farm to consumer.
Vertical farming would convert this blackwater (waste) and greywater into potable water by collecting the water released into the air by evapotranspiration. Vertical Farming supports the concept of “addressing food production in a modern city, where urban wastes, like black water will be composted, recycled and used for farming inside a standard tenement-like building. Such risks include: exposure to infectious diseases such as malaria and schistosomes, exposure to toxic chemicals commonly used as pesticides and fungicides, confrontations with dangerous wildlife such as poisonous snakes, and the severe injuries that can occur when using large industrial farming equipment.
However, a recent analysis suggests that transportation is only a minor contributor to the economic and environmental costs of supplying food to urban populations. He had originally challenged his class to feed 50,000 Manhattanites using 13 acres of useable rooftop gardens.
This biogas could then be burned to generate electricity that can either be consumed at the farm or added to the grid. Vertical farming relies on the use of various physical methods to become effective. Although the controlled environment of vertical farming negates most of these factors, earthquakes and tornadoes still pose threats to the proposed infrastructure, although this again depends on the location of the vertical farms. Each acre in a vertical farm could allow between 10 and 20 outdoor acres of farmland to return to its natural state, and recover farmlands due to development from original flat farmlands. Vertical farming would reduce the need for new farmland due to overpopulation, thus saving many natural resources, currently threatened by deforestation or pollution.
Vertical farms, if designed properly, may eliminate the need to create additional farmland and help create a cleaner environment by using recycling techniques rather than harming the environment by using traditional farming techniques. Unlike traditional farming, indoor farming can produce crops year-round. This will be expected to improve the living conditions since transportation costs in handling food supply and wastes will be greatly reduced. The city s sewage sludge will enter a machine called “SlurryCarb”, to break down the sludge into carbon and water.
Also, pure Oxygen produced by photosynthesis of the crops would be released into the environment adding to the improvement of air quality surrounding the Vertical Farm. The controlled growing environment reduces the need for pesticides, herbicides, and fertilizers. He also states that the system can be profitable and effective, a claim evidenced by some preliminary research posted on the project s website.
Combining these technologies and devices in an integrated whole is necessary to make Vertical Farming a reality. Advocates claim that producing organic crops in vertical farms is practical and the most likely production and marketing strategy. Because water recycling is more practical and economical in a controlled agricultural environment, vertical farming would use much less water than traditional farming.
Part of the sludge will be treated with chemicals to kill the bacteria and will undergo heating and drying process that will convert the treated sludge into topsoil. Developers and local governments in the following cities have expressed serious interest in establishing a vertical farm: Inchon (South Korea), Abu Dhabi (United Arab Emirates), and Dongtan (China), Critics have noted that the energy needed for artificial lighting and other vertical farming operations might outweigh the benefit of the building’s close proximity to the areas of consumption.
Whereas the traditional farming environment inevitably contains these risks (particularly in the farming practice known as “slash and burn”), vertical farming – because the environment is strictly controlled and predictable – eliminates them altogether. Vertical farming, used in conjunction with other technologies and socioeconomic practices, could allow cities to expand while remaining largely self sufficient. With some crops, such as strawberries, the factor may be as high as 30. Furthermore, as the crops would be sold in the same infrastructures in which they are grown, they will not need to be transported or refrigerated between production and sale, resulting in far less spoilages and infestations than conventional farming encounters.
Various methods are proposed and under research. There will be sensors for every single plant that tracks how much and what kinds of nutrients the plant has absorbed.
Their proponents argue that, by allowing traditional outdoor farms to revert to a natural state and reducing the energy costs needed to transport foods to consumers, vertical farms could significantly alleviate climate change produced by excess atmospheric carbon. Dickson Despommier, a professor of environmental health sciences and microbiology at Columbia University in New York City, developed the idea of vertical farming in 1999 with graduate students in a medical ecology class. Producing food indoors reduces or eliminates conventional plowing, planting, and harvesting by farm machinery, also powered by fossil fuels.
Moreover, the industry of vertical farming will provide employment to these expanding urban centers. dwarf wheat developed by NASA, which is smaller in size but richer in nutrients Crops grown in traditional outdoor farming suffer from the often suboptimal, and sometimes extreme, nature of geological and meteorological events such as undesirable temperatures or rainfall amounts, earthquakes, monsoons, hailstorms, tornadoes, flooding, wildfires, and severe droughts. Because Vertical Farming provides a controlled environment, the productivity of vertical farms would be mostly independent of weather and protected from extreme weather events.
New York City dumps 1.4 billion gallons of “treated waste water” into its rivers daily. It is unlikely that traditional farms will become obsolete, as there are many crops that are not suited for vertical farming. Proponents claim that vertical farms could generate power.
All-season farming multiplies the productivity of the farmed surface by a factor of 4 to 6 depending on the crop. Using recycled resources and greenhouse methods such as hydroponics, these buildings would produce fruit, vegetables, edible mushrooms and algae year-round.
The author of the report, University of Toronto professor Pierre Desrochers, concluded that food miles are, at best, a marketing fad. . This may help displace the unemployment created by the dismantling of traditional farms, as more farm laborers move to cities in search of work.
In an interview with Miller-McCune.com; Despommier described how vertical farms would function: Each floor will have its own watering and nutrient monitoring systems. Nevertheless, Despommier has argued that the idea is plausible.
