Risks of irreversible biodiversity loss

Hainzelin E.. 2019. In : Dury Sandrine (ed.), Bendjebbar Pauline (ed), Hainzelin Etienne (ed.), Giordano Thierry (ed.), Bricas Nicolas (ed.). Food systems at risk. New trends and challenges. Rome : CIRAD, FAO, p. 59-62.

Biodiversity is the driving force of ecosystem services and has been the foundation of agriculture for many, many years. The drastic evolution of agriculture over the past century in industrialised and some developing countries, based on improved varieties and synthetic inputs, greatly increased production but has led to the artificialisation of agroecosystems and great losses of specific and genetic diversity. In turn, these losses have hampered food systems in different ways: degraded ecosystem services affecting crop yields and resilience, reduced crop biodiversity, and highly specialised industrialised food processing, which has decreased the diversity of the food supply and its nutritional value.
