Vertical farming is a modern space-saving method for producing food and medicine in vertically stacked layers. This growing method is especially effective in highly dense cities with a large demand for food but limited space.
Indoor farming techniques and controlled-environment agriculture (CEA) technologies are often used for vertical farms. This allows environmental factors to be controlled and therefore optimises plant growth and reduces the chance of a pest outbreak. Soilless farming techniques such as hydroponics, aquaponics and aeroponics are the common growing techniques used in vertical farming.
One of the biggest benefits of sustainable vertical farming is the reduction of CO2 emission. Currently, the agricultural sector emits around 13% of the total greenhouse gas emission in the world. Second to only the biggest polluter, the energy sector. Vertical farms save energy by using renewable energy source and high efficiency LED lightings.
The transportation of food creates a large amount of CO2 every year. By growing food closer to its consumers, big savings can be made in transportation. Therefore, vertical farming is greatly beneficial when it comes to growing fresh produce near highly dense cities where conventional farms are often too far away.
