What is a vertical farm?
The concept of vertical farm first appeared in 1999. Dickson Despommier, a professor of environmental health science and microbiology, proposed in a discussion with graduate students that a 30 story farm in a block can provide food for 50000 people, including vegetables, fruits, eggs and meat, and explained that hydroponic crops can be planted on the top; The lower floors are suitable for feeding chickens and fish fed with plant waste.
However, after calculation, the roof garden covering an area of 5 hectares (13 acres) can only provide food for 2% of the population of Manhattan (about 2 million people). So Professor Dickson began to study indoor vertical cultivation plants. By 2001, the vertical farm had the first outline.
In recent years, countries have been trying to vertical farms, but at present, aerofarms is the largest vertical farm in the world and the leader in the field of vertical agriculture.
