With a growing world population that will reside in urban centers, and shrinking space for growing crops, some argue that cities of the future must generate their own food supply. The simple answer for achieving this goal is ‘vertical farming’, hydroponic food production in cities in multi-story greenhouses. Urban agriculture can go horizontal and vertical. Vertical farms purpose to avoid the problems inherent in growing food crops in drought-and-disease-prone fields many hundreds of kilometres from the population centres in which they will be consumed. So, one of advantages of vertical farming is people feed the world in a safe sustainable way.

What is new is the urgent need to scale up this technology to accommodate another 3 billion people. An entirely new scientific approach to vertical farming must be invented, employing cutting edge technologies. The Vertical Farm must be efficient, cheap to construct and safe to operate. Vertical farms, many stories high, will be situated in the heart of the world’s urban centers.
An ecologist, Dickson Despommier, Columbia University in New York City who has championed vertical farms since 1999 – in high-rise urban buildings, the food should be grown year-round, reducing the need for the carbon-emitting transport of fruit and vegetables. If vertical farm succeed to implement, they offer the promise of urban renewal, sustainable production of a safe and varied food supply (year-round crop production), and the eventual repair of ecosystems that have been sacrificed for horizontal farming. The following are some advantages of vertical farming if we can apply in urban city.
Advantages of Vertical Farming
- Year-round crop production; 1 indoor acre is equivalent to 4-6 outdoor acres or more, depending upon the crop (e.g., strawberries: 1 indoor acre = 30 outdoor acres)
- Vertical Farm Systems growing cycles are consistent and reliable, allowing commercial growers to confidently commit to delivery schedules and supply contracts
- By removing soil from the growing of greens, vertical farming improve food safety by avoiding completely contaminated manure and irrigation water. All Vertical Farming food is grown organically: no herbicides, pesticides, or fertilizers
- Vertical Farming virtually eliminates agricultural runoff by recycling black water
- Vertical Farming returns farmland to nature, restoring ecosystem functions and services
- Vertical Farming greatly reduces the incidence of many infectious diseases that are acquired at the agricultural interface
- Vertical Farming converts black and gray water into potable water by collecting the water of evapotranspiration
- Vertical Farming adds energy back to the grid via methane generation from composting non-edible parts of plants and animals
- Vertical Farming dramatically reduces fossil fuel use (no tractors, plows, shipping.)
- Vertical Farming converts abandoned urban properties into food production centers
- Vertical Farming produces sustainable environments for urban centers
- Vertical Farming produces new employment opportunities
- Vertical Farming offers the promise of measurable economic improvement for tropical and subtropical LDCs. If this should prove to be the case, then Vertical Farming may be a catalyst in helping to reduce or even reverse the population growth of LDCs as they adopt urban agriculture as a strategy for sustainable food production.
- Using high efficiency, LED lighting technology, to ensures minimum power usage for maximum plant growth
- Vertical Farming could reduce the incidence of conflict or take over because natural resources, such as water and land for agriculture
