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).
Controlled-environment agriculture (CEA) -- which includes indoor agriculture (IA) and vertical farming—is a technology-based approach toward food production. The aim of CEA is to provide protection from the outdoor elements and maintain optimal growing conditions throughout the development of the crop.
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.
