” This was the very first time anyone has collected the food and feed streams in this information internationally, from both terrestrial and aquatic systems, and integrated them together. That let us comprehend just how much of the food spin-offs and residues is currently in usage, which was the first action to identifying the untapped capacity,” describes Kummu.
Researchers examined the capacity of using crop residues and food spin-offs in livestock and aquaculture production, maximizing the human-usable material to feed people.
The investigators analyzed the flow of food and feed, along with their by-products and residues, through the international food production system. They then recognized ways to shift these circulations to produce a better result. For example, livestock and farmed fish could be fed food system spin-offs, such as sugar beet or citrus pulp, fish and livestock spin-offs, or perhaps crop residues, rather of materials that are suitabled for human use..
With these basic changes, approximately 10-26% of total cereal production and 17 million lots of fish (~ 11% of the current seafood supply) could be rerouted from animal feed to human usage. Depending upon the precise situation, the gains in the food supply would be 6-13% in terms of calorie material and 9-15% in terms of protein content. “That may not sound like a lot, however thats food for approximately about one billion individuals,” says Vilma Sandström, the very first author of the study and Postdoctoral Researcher at Aalto University.
These findings dovetail nicely with earlier work from Kummus group on minimizing food loss throughout the supply chain, from production, transportation, and storage through to consumer waste. “In that research study, we revealed that decreasing food loss and waste by half would increase the food supply by about 12%. Combined with utilizing spin-offs as feed, that would be about one-quarter more food,” he states.
Some of the modifications, such as feeding crop residues to livestock, would lead to a drop in animals efficiency, the scientists currently accounted for that in their analysis. Another difficulty is that the human-edible food presently used in livestock production and aquaculture is various from the food people are used to. A various range of corn is used in feed industries and some of the grains are of lower quality. The fish utilized in fishmeal production tend to be small, bony fish that currently arent popular with consumers.
Nevertheless, conquering these obstacles could lead to substantial gains, though ealizing these advantages would require some adjustments in supply chains. “For example, we d need to restructure the food system so that the industries and producers with by-products can discover the animals and aquaculture manufacturers who would need them. And some of the by-products would require processing prior to utilizing them as feed,” says Sandström.
” I dont think theres any severe issue with doing this. What were suggesting is currently being done on a specific scale and in some locations, so its not something that would have to be established from scratch. We just require to change the present system and increase the scale of those practices,” Kummu concludes.

Even with millions around the world dealing with the risk of scarcity or poor nutrition, the production of feed for livestock and fish is tying up minimal natural resources that could be utilized to produce more food for people. New research study from Aalto University, published today (September 19) in Nature Food, reveals how adjustments to the feeding of animals and fish could preserve production while making more food available for people. The detectives evaluated the circulation of food and feed, as well as their residues and spin-offs, through the worldwide food production system. “In that research study, we showed that reducing food loss and waste by half would increase the food supply by about 12%. Another obstacle is that the human-edible food presently utilized in livestock production and aquaculture is different from the food people are used to.
Materials currently fed to livestock and fish might be redirected to increase the amount of food offered for people.
Animals and fish might be fed more farming spin-offs, freeing up more food for people.
Even with millions around the world facing the hazard of starvation or malnutrition, the production of feed for livestock and fish is tying up minimal natural resources that could be utilized to produce more food for people. New research study from Aalto University, released today (September 19) in Nature Food, shows how modifications to the feeding of livestock and fish could keep production while making more food readily available for people.
Approximately a 3rd of cereal crop production is currently used as animal feed, and about a quarter of caught fish arent utilized to feed people. Matti Kummu, an associate teacher of worldwide water and food problems at Aalto University, led a team of scientists that investigated the potential of using crop residues and food by-products in animals and aquaculture production to free up the human-usable material to feed individuals.
