It’s a form of cultivation aimed at producing a large quantity of fruit and vegetables on a small plot of land by imitating the way nature works (without pesticides, synthetic fertilizers or mechanically working the soil, etc.).

Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants. A hydroponic and aquaculture farming techniques form the basis of all aquaponic systems.

The farming of aquatic organisms including fish, mollusks, crustaceans and aquatic plants. Farming implies some sort of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc. Farming also implies individual or corporate ownership of the stock being cultivated, the planning, development and operation of aquaculture systems, sites, facilities and practices, and the production and transport.  Aquaculture is an approximate aquatic equivalent to agriculture—that is, the rearing of certain marine and freshwater organisms to supplement the natural supply.

Vertical farming is the practice of growing crops in vertically stacked layers. It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. The main advantage of utilizing vertical farming technologies is the increased crop yield that comes with a smaller unit area of land requirement.
