Agrobiodiversity is a term coined toward the end of the last millennium after the Rio conference on biodiversity. Important features of agrobiodiversity have been developed from a synthesis of biodiversity research and the genetic resources approach. The aim of agrobiodiversity is to include all crops and livestock, wild relatives, interacting species-pollinators, symbionts, pests, parasites, predators, and competitors. As in the discussions of biological diversity, three levels are generally acknowledged: genetic diversity, species diversity, and the diversity of ecosystems. Genetic erosion, that is, the disappearance of a large number of traditional races and breeds and the predominance of a limited number of high-bred organisms, leads to a tremendous loss of valuable genes. This particular process within agrobiodiversity is under intensive discussion, but a coherent theory has yet to be developed. In addition, for the strongly interacting elements of agrobiodiversity a generalized model is still far from being available.
