Vertical Farming


World population in 2050 to 9 billion, about 80% of whom were urban dwellers. Mankind may be facing a dilemma: on the one hand, consolidation of cities selected by more and more land suitable for agriculture, and, on the other hand, in order to feed so many people need grounds with Brazil. One possible way to solve the food problem of the future may be vertical farm, located directly in the city.

Stucture of vertical farm

Every year the area of arable land is decreasing. So, if in 1950 each person had about 0.52 hectares, by 2050 this figure will be less than 0.19 ha. Solve future problems, scientists are trying different ways: some propose to grow the plants in the deserts, and others - to move a farm in the city, giving impetus to the development of urban "rural " economy.

Hydroponic and aeroponic methods for growing plants

In the development of vertical farms as a basis for going to take a well-established hydroponic and aeroponic methods of growing plants. Hydroponics (from the Greek. «hydro» - water and «ponos» - work that is "working solution") - a technology of growing plants without soil, in a nutrient aqueous solution containing the optimal concentration of easily digestible form and all necessary materials for concrete taken of the plant.

Aeroponic (air-culture) - a technology of growing plants without soil and substrates, in which the roots are in the air, and the necessary substances to flow through drip spraying nutrient solution. Nutrient mixture fed continuously or at frequent intervals, so that the roots have not had time to dry.

Both technologies are superior to traditional approaches to environmental impact and volume of crops, obtained from 1 ha, as well as significantly reduce water consumption. Thus, for the aeroponic method of growing plants require only 1 / 10 of the water expended in the classical agricultural methods.

Advantages of vertical farming

  1. Year-round crop production.
  2. Eliminates agricultural runoff.
  3. Significantly reduces use of fossil fuels (farm machines and transport of crops).
  4. Makes use of abandoned or unused properties.
  5. No weather-related crop failures.
  6. Offers the possibility of sustainability for urban centers.
  7. Converts black and gray water to drinking water by collecting the water of transevaporation.
  8. Adds energy back to the grid via methane generation using inedible parts of crop plants.
  9. Creates new urban employment opportunities.
  10. Reduces the risk of infection from agents transmitted at the agricultural interface.
  11. Returns farmland to nature, helping to restore ecosystem functions and services.

Urban farming

Urban agriculture is the practice of cultivating, processing and distributing food in, or around (peri-urban), a village, town or city. Urban agriculture in addition can also involve animal husbandry, aquaculture, agro-forestry and horticulture. These activities also occur in peri-urban areas as well. Urban farming is generally practiced for income-earning or food-producing activities though in some communities the main impetus is recreation and relaxation. Urban agriculture contributes to food security and food safety in two ways: first, it increases the amount of food available to people living in cities, and, second, it allows fresh vegetables and fruits and meat products to be made available to urban consumers. A common and efficient form of urban agriculture is the biointensive method. Because urban agriculture promotes energy-saving local food production, urban and peri-urban agriculture are generally seen as sustainable practices. The recognition of environmental degradation within cities through the relocation of resources to serve urban populations has inspired the implementation of different schemes of urban agriculture across the developed and developing world. From historic models such as Machu Picchu to designs for new productive urban farms, the idea of locating agriculture in or around the city takes on many characteristics.
