Vertical farming or high-rise farming is a proposed indoor, urban
farming technology involving large-scale agricultural production in
multi-story buildings. It is an intensive farming strategy which
mainly employs advanced techniques such as hydroponics and
aeroponics to produce crops like fruits, vegetables and edible
mushrooms continuously. 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 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 between production and
sale, resulting in less spoilage, infestation, and energy required
than conventional farming encounters. 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, monsoons, hailstorms,
tornadoes, flooding, wildfires, and severe droughts. The protection
of crops from weather is increasingly important as global climate
change occurs. Because vertical plant farming provides a controlled
environment, the productivity of vertical farms would be mostly
independent of weather and protected from extreme weather events.
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. With high-rise farming, a
relatively large area of land will be converted into a facility on
which a multi-story building will be constructed. It will be
located in the urban center. Important food crops will be grown in
this building on soil-less media, employing mainly the techniques
in hydroponics. 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. 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.
