Monoculture
Definition
Monoculture is an agricultural production system in which a single crop species is grown repeatedly on the same land area, often over large scales and multiple seasons. It enables mechanisation, uniform management and high short-term yields, but concentrates biological and environmental risk by reducing genetic and ecological diversity.

Overview
What it means
Repeated single-crop cultivation depletes specific soil nutrients, builds pest and disease pressure (raising pesticide dependence), reduces habitat for pollinators and wildlife, and erodes genetic diversity — the vulnerability illustrated by the 1950s loss of the Gros Michel banana to Panama disease.
How it is used
The term anchors critiques of industrial agriculture and motivates alternatives — crop rotation, intercropping, agroforestry, regenerative systems — assessed in soil-health and biodiversity policy.
Why it matters
Most global cropland is monocropped; its hidden costs (soil degradation, input dependence, fragility to shocks) are central to the case for diversifying food systems.
