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.

Emerging in North America in the 1970s and 1980s, vertical tillage (VT) is a system of principles and guidelines similar to conservation agriculture (CA) in that it aims to improve soil health, increase water infiltration and decrease soil erosion and compaction (improve bulk density).
The greenhouse industry is the second largest component of the CEA industry but another quickly growing segment is the vertical farming industry. Controlled Environment Agriculture has the ability to produce crops all year round, with the possibility of increased yield by adjusting the amount of carbon and nutrients the plants receive.
Findbusinesses4sale explored what the rise of vertical farming can mean for domestic food production, using Department of Agriculture data.
In practice, vertical farms employ advanced techniques such as hydroponics or aeroponics, allowing plants to grow without soil by using nutrient-rich water or air instead. By utilizing vertical space, these farms achieve higher crop yields per square foot compared to conventional farming methods.
There are also challenges to farmers who rely on farming equipment optimized for monoculture, often resulting in increased labor inputs. Vertical farming is intensive crop production on a large scale in urban centers, in multi-story, artificially-lit structures, for the production of low-calorie foods like herbs, microgreens, and lettuce.
The AVF acknowledges that vertical farming in its current state can provide access to fresh, safe, and sufficient food, independent of climate and location. In the decades to come, where overpopulation and severe planetary changes challenge our current way of life, vertical farming will become a necessary solution in global food production.
In September 2016, the AeroFarms Global Headquarters opened in a 70,000 square-foot facility in Newark, which is the largest indoor vertical farm in the world based on annual growing capacity. [5] The farm was built in a 75-year-old former steel mill facility and has the capacity to produce up to two million pounds of leafy greens per year. [6]
