Monoculture
Growing a single crop species repeatedly on the same land — efficient in the short term but degrading soil, biodiversity and resilience.
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.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.
Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.
Only an editor-accepted synthesis changes the public page. Reviewer identities are shown only with consent and an editorial decision to attribute them.
Submitted reviews stay private until an editor decides whether to accept and attribute them.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
