Since they were initially introduced in 2010, the number of vertical farms in Asia, Europe, and North America has increased to the point where there are now several hundred farms in those regions. Vertical farms are a new type of controlled environment agriculture (CEA) that make use of a variety of different technologies. Vertical farms can be conceptualized as a stack of greenhouses stacked on top of each other, with the plant yield being multiplied by the number of floors that make up the vertical farm. It is now a solution to the majority of the problems that are caused by traditional outdoor farming. Because it requires less land, it can help contribute to the restoration of forests. Additionally, because it operates within the framework of a circular economy, it utilizes fewer resources and recycles organic waste. Because of its role in the transmission of infectious diseases around the world, outdoor farming may also have substantial effects on people's health. Although vertical farms require a high-tech environment, which is typically only available in countries with high levels of economic development, the model has the potential to become more popular in the coming years as a workable solution to increase food sufficiency in cities all over the world with the support of local authorities and international organizations, in addition to the proliferation of large commercial growers.
