Redirecting Agricultural Byproducts as Animal Feed Could Provide More Food for People

Research at Aalto University in Finland revealed that diverting agricultural byproducts for use as livestock and fish feeds could make food for as many as a billion people available without additional natural resource use or diet changes. According to a press release, a team analyzed the flow of food and feed, as well as their byproducts and residues, through the global food production system. They then identified ways to shift these flows to produce a better outcome. For example, livestock and farmed fish could be fed food-system byproducts, such as sugar beet or citrus pulp, fish and livestock by-products, or even crop residues, instead of materials that are fit for human use. Researchers concluded that with these changes, 10 to 26% of total cereal production and 17 million tons of fish (approximately 11% of the current seafood supply) could be redirected from animal feed to human use.
