Farm-free production systems refer to systems that generate food or types of fuel or fibre that are conventionally produced by agricultural systems but which are not produced on a farm. An example of a farm-free production system is the production of cellular meat in a bioreactor. While advocates of farm-free production systems tend to point towards potentially radical reductions in agricultural land use to produce a certain amount of food (or other products), farm-free production systems can be based on the use of ingredients (such as corn starch or soy protein) that are derived from more land-intensive production systems.
