The world wasted an estimated 19% of the food produced globally in 2022, or about 1.05 billion metric tons, according to a newThe U.N. said the number of countries reporting for the index nearly doubled from the first report in 2021. The 2021 report estimated that 17% of the food produced globally in 2019, or 931 million metric tons , was wasted, but authors warned against direct comparisons because of the lack of sufficient data from many countries.
Most of the waste came in households . About 28% came from food service, or restaurants, with about 12% from retailers. Fadila Jumare, a Nigeria-based project associate at Busara Center for Behavioral Economics who has studied prevention of food waste in Kenya and Nigeria, said the problem further disadvantages many people who are already food insecure and cannot afford healthy diets.
“The key takeaway is that reducing the amount of food that is wasted is an avenue that can lead to many desirable outcomes — resource conservation, fewer environmental damages, greater food security, and more land for uses other than as landfills and food production,” said Roe, who wasn’t involved in the report.
The report said food redistribution — including donating surplus food to food banks and charities — is significant in tackling food waste among retailers.
