As the population increases and food demand rises, agricultural production is under increased pressure to produce higher yields. By 2050, the global population is expected to reach 9.7 billion people, with 70% of them living in cities and furthermore, agricultural land may be lost as a result of urbanization and infrastructure growth, possibly resulting in farmland shortages (Lotze-Campen et al., 2008; Thomaier et al., 2015).
Since the amount and yield of agricultural land available for traditional farming is small, this scale of change will necessitate the investigation of novel food production methods. Every day, we lose arable lands used for farming and maintaining our enormous lives due to the acclimatization of human industrial growth and urbanization. In 2015, scientists announced that over the previous 40 years, the Earth had lost a third of its arable land.
Many studies and experiments are being conducted in parallel to alleviate the issue, but vertical farming is the only solution to all of the serious problems. All of these measures, which were once ground-breaking, now seem insufficient. Gilbert Ellis Bailey invented the word "vertical farming" and published the book "Vertical Farming" in 1915.
