Increasing biodiversity
By growing heirloom and other non-commercial varieties, small farms bolster biodiversity and increase food security. With only 12 plants and five animal species making up 75 percent of what the world eats, food systems are vulnerable to natural disasters and disease outbreak.
Traditional farming communities like El Choro in Bolivia are working to preserve their ancient seed diversity. By planting and harvesting ancestral varieties of quinoa and over 150 varieties of traditional potatoes, they’re building up a store of seeds and making them accessible to growers.
