What does it actually mean? It refers to the different ways in which nature expresses itself on our planet. All the different animal and plant species we see every day are the result of biodiversity. Part of this great heritage is defined as agricultural biodiversity, that is, the set of plant varieties and animal breeds that were once used in a certain territory and characterized it as all the food and wine, landscape, cultural and historical traditions of that place and the people who lived it.
FAO estimates that three quarters of the genetic biodiversity of agricultural crops have disappeared in the last century, so much so that human nutrition currently depends on only a few species of plants. Many varieties and breeds are now extinct, therefore lost forever, but others have been preserved thanks also to the farmers and breeders custodians of biodiversity, people who knew and wanted to preserve this ancient genetic heritage.
