Vertical Farming 2 types of Skyscrapers Mixed-use skyscrapers Despommier's skyscrapers Energy Use Economics Pollution Preparing for the Future Common Technology Used: Technologies and devices It is estimated that by the year , 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. A very large amount of land may be required depending on the change in yield per hectare. 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. Vertical farms, if designed properly, may eliminate the need to create additional farmland and help create a cleaner environment. *Greenhouse

*Aeroponics / Hydroponics / Aquaponics
*Controlled-environment agriculture Regular greenhouse produce is known to create more greenhouse gases than field produce, largely due to higher energy use per kilogram of produce. With vertical farms requiring much greater energy per kilogram of produce, mainly through increased lighting, than regular greenhouses, the amount of pollution created will be much higher than that from field produce. As 'The Vertical Farm' proposes a controlled environment, heating and cooling costs will be at least as costly as any other tower. But there also remains the issue of complicated, if not more expensive, plumbing and elevator systems to distribute food and water throughout. Even throughout the northern continental United States, while heating with relatively cheap fossil fuels, the heating cost can be over $200,000/hectare.
To address this problem, The Plant in Chicago is 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. Mixed-use skyscrapers
Despommier's skyscrapers The second category of vertical farming falls under the concepts proposed and built by architect Ken Yeang developed at least ten years before Despommier. Yeang proposes that instead of hermetically sealed mass produced agriculture that plant life should be cultivated within open air, mixed-use skyscrapers for climate control and consumption (i.e. a personal or communal planting space as per the needs of the individual). This version of vertical farming is based upon personal or community use rather than the wholesale production and distribution plant and animal life that aspires to feed an entire city. It thus requires less of an initial investment than Despommier's "The Vertical Farm". However, neither Despommier nor Yeang are the conceptual "originators", nor is Yeang the inventor of vertical farming in skyscrapers. The third category vertical farming was made by American ecologist Dr. Dickson Despommier. Despommier argues that vertical farming is legitimate due to environmental reasons. He claims that the cultivation of plant and animal life within skyscrapers will produce less embedded energy and toxicity than plant and animal life produced 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 relies on the use of various physical methods to become effective. Combining these technologies and devices in an integrated whole is necessary to make Vertical Farming a reality. Various methods are proposed and under research. The most common technologies suggested are: -> * Plants grown in the building. Preparing for the Future &
Common Technology Used Grow Light Green House A greenhouse with its lights on at night, contributing to light pollution. 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 in order to obtain economically viable yields. Bruce Bugbee, a crop physiologist at Utah State University, believes that the power demands of vertical farming will be too expensive and uncompetitive with traditional farms using only free natural light.The scientist and climate change activist George Monbiot calculated that the cost of providing enough supplementary light to grow the grain for a single loaf would be almost $10 (altrough his calculation has not considered LED growing lights, which are significantly more efficient). Opponents question the potential profitability of vertical farming. A detailed cost analysis of start-up costs, operation costs, and revenue has not been done. The extra cost of lighting, heating, and powering the vertical farm may negate any of the cost benefits received by the decrease in transportation expenses.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. 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 author of the report, University of Toronto professor Pierre Desrochers, concluded that "food miles are, at best, a marketing fad.
