FAO Director-General José Graziano da Silva explained “Biodiversity is essential for safeguarding global food security and nutrition, improving rural livelihoods, and enhancing the resilience of people and communities."
He pointed out that the world still produces food based mainly on 50-year-old principles, often using environmentally unfriendly chemicals, he also described how the loss of agricultural biodiversity poses a direct risk to food security.
“Only three staple crops — rice, maize and wheat — and three animal species — cattle, pigs, and chicken — provide the majority of food energy intake in the world,” he said. Diversifying food sources could play a critical role in ensuring food security; such as genetically diverse plants which are more tolerant to hotter and drier conditions, he said. Similarly, more diverse livestock would allow farmers and pastoralists to breed animals which could adapt to changing environmental conditions.
