A new concept of food production is giving the talk between architects and conservationists in major world cities: the vertical farms, which are the structures of the building whose activity in their stories is agriculture. Created by the biologist Dickson Despommier, in 1999, the method would be as large greenhouses on each floor, to grow vegetables, fruit and other crops, use the hydroponics (cultivation method that does not use the land, water and minerals). Some projects also include the creation of birds and fish on the first floor.But, for that to practice agriculture on a building? A problem with the traditional farms? Well, as you all know, the land for growing food and breeding of animals for human consumption are increasingly scarce. With more than 9 billion mouths to be fed by 2050, how to get food for everybody? In addition to the lack of space, the dependence of rain, sunshine, humidity and other climatic variables makes production losses of up to 40%. It is no longer possible to be at the mercy of the consequences of global warming to produce food. And the vertical farm, where plants and animals are reared in a closed environment, temperature, humidity, carbon dioxide emissions and lighting controlled, come to put an end to this problem. Deforestation would be drastically reduced.The positive points of this kind of food production are many: in addition to consume 30% less water, on account of hydroponics, the main advantage is proximity to the consumer, reducing transportation costs and greenhouse gas emissions therefrom. The incidence of pests would also be reduced, and the use of pesticides. And the waste generated can be used to produce energy in lighting and to maintain the internal temperature.The big disadvantage of the vertical farm is in its high cost of development and deployment activities. Build greenhouses large vertical with the entire apparatus to control the cultivation of plants and animals in an urban environment is still very expensive. That is, although the idea has emerged in 1999, still there is no vertical farm in the world, as it was conceived by its creator. What are there are prototypes of farms, or reduced models, so to speak. This is because the idea, because it is very in tune with the optimization of natural resources to meet the needs of mankind, is being tested and enhanced to work.Do a quick search and you will find that many countries have several projects of "high tech fields. Just as it was with the cellular phone (remember how they were expensive and large the first apparatus?) This is already being with the vertical farms. In my opinion, they do not come to break with the traditional farms, but to be an ally in the fight against hunger and for sustainability.
