NEW YORK (AP) — A new report from the United Nations estimates that 17% of food produced globally is wasted each year. But the report notes the need for better data on food waste globally, with few countries tracking it well. The authors are hoping the report will encourage countries to invest in measuring waste. Brian Roe, a food waste researcher at Ohio State University, says improved measurement can lead to improved management. The report estimates that most of food waste — or 61% — happens in households. Food service accounts for 26% and retailers account for 13%.
