Agricultural biodiversity or agrobiodiversity is a subset of general biodiversity pertaining to agriculture. It can be defined as "the variety and variability of animals, plants and micro-organisms at the genetic, species and ecosystem levels that sustain the ecosystem structures, functions and processes in and around production systems, and that provide food and non-food agricultural products.” It is managed by farmers, pastoralists, fishers and forest dwellers, agrobiodiversity provides stability, adaptability and resilience and constitutes a key element of the livelihood strategies of rural communities throughout the world. Agrobiodiversity is central to sustainable food systems and sustainable diets. The use of agricultural biodiversity can contribute to food security, nutrition security, and livelihood security, and it is critical for climate adaptation and climate mitigation.
It is not clear when exactly the term agrobiodiversity was coined nor by whom. The 1990 annual report of the International Board for Plant Genetic Resources (IBPGR, now Bioversity International) is one of the earliest references to biodiversity in the context of agriculture. Most references to agricultural biodiversity date from the late 1990s onwards.
While similar, different definitions are used by different bodies to describe biodiversity in connection with food production. CGIAR tends to use agricultural biodiversity or agrobiodiversity, while the Food and Agriculture Organization of the UN (FAO) uses 'biodiversity for food and agriculture' and the Convention on Biological Diversity (CBD) uses the term 'agricultural diversity'. The CBD more or less (but not entirely) excludes marine aquatic organisms and forestry in its usage because they have their own groups and international frameworks for discussion of international policies and actions. Decision V/5 of the CBD provides the framing description.
Genetic diversity refers to the variety and variability within and between species.

A 'center of origin' is a geographical area where a group of organisms, either domesticated or wild, first developed its distinctive properties. They are also considered centers of diversity. Centers of origin were first identified in 1924 by Nikolai Vavilov. Locating the origin of crop plants is basic to plant breeding. This allows one to locate wild relatives, related species, and new genes (especially dominant genes, which may provide resistance to diseases).
Genetic erosion (also known as genetic depletion) is a process where the limited gene pool of an endangered species diminishes even more when reproductive individuals die off before reproducing with others in their endangered low population. The term is sometimes used in a narrow sense, such as when describing the loss of particular alleles or genes, as well as being used more broadly, as when referring to the loss of a phenotype or whole species.
