Agrobiodiversity is a sub-set of general biodiversity including all cultivated varieties. Cultivated varieties can be broadly classified into “modern varieties” and “farmer’s or traditional varieties”. Modern varieties are the outcome of scientific breeding and are characterised by a high yield and a high degree of genetic uniformity. In contrast, farmer’s varieties (also known as landraces) are the product of breeding or selection carried out by farmers. They represent higher levels of genetic diversity and are therefore the focus of most conservation efforts. Agricultural biodiversity contributes to food security and livelihood security and underpins the development of all food production. It is the first link in the food chain, developed and safeguarded by farmers, livestock breeders, forest workers, fishermen and indigenous peoples throughout the world.
According to FAO Agrobiodiversity, "encompasses the variety and variability of animals, plants and micro-organisms which are necessary to sustain key functions of the agroecosystem, its structure and processes for, and in support of, food production and food security". It is the product of sustainable agro ecological production systems and these systems simultaneously depend on a wide range of agricultural biodiversity.
