A shorthand for agricultural biodiversity, is a subset of the broader concept of biodiversity. Agrobiodiversity refers to that aspect of biodiversity related to agriculture and farm animals and is linked to agricultural ecosystems (agroecosystems), genetic variation of crops and farm animals, and other features associated with agriculture such as soils and insects. The concept of agrobiodiversity and its link to home gardens are the focus of a volume edited by Eyzaguirre and Linares (2004). [JG]
