Monoculture - Wikipedia

Monoculture is the agricultural practice of producing or growing one single crop over a wide area. It is also known as a way of farming practice of growing large stands of a single species. It is widely used in modern industrial agricultureand its implementation has allowed for large harvests from minimal labor. However, monocultures can lead to the quicker spread of diseases, where a uniform crop is susceptible to a pathogen. 'Crop monoculture' is the practice of growing the same crop year after year.[1]

The term is frequently borrowed for other uses, such as raising one species of livestock in a factory farm, or even in fields other than agriculture to describe any group dominated by a single variety, e.g. in the field of musicology to describe the dominance of the American and British music-industries in pop music, or in the field of computer science to describe a group of computers all running identical software.
