Dyson School of Applied Economics and Management and founding director of the Tata-Cornell Agriculture and Nutrition Initiative at Cornell University, pointed out that the measures also show how the food loss and waste situation differs when looking at developed or developing countries. FOOD LOSS MEASURES: STATE OF KNOWLEDGE AND KNOWN CHALLENGES Carola Fabi, statistician at the Food and Agriculture Organization of the United Nations (FAO)

Fabi stressed that no one size fits all due to different circumstances across countries and that a range of statistical tools and methods are needed to gather data on losses and waste. Solutions include partnerships with the private sector, especially food processing industries, and a newly developed loss imputation model.

USDA/ERS MEASUREMENT OF FOOD LOSS IN THE UNITED STATES Jean Buzby, chief of the Diet, Safety, and Health Economics Branch at the USDA's Economic Research Service (ERS) , described how the ERS estimates food loss in the United States, how the estimates are used, and plans for developing better indicators of food loss by ERS and of food waste by the U.S.

, a secondary purpose is to provide estimates of food loss at the retail and consumer levels in the United States (which include food waste as described in the ERS definition above)

Efforts include an expert panel on technical questions and data gaps (see Box 2-1) ; updates of estimates using the Food Acquisition Purchase Survey (Food-APS)

continually seeks to improve its data collection and use, with two efforts highlighted by Mary Muth, director of the Food, Nutrition and Obesity Policy Research Program at RTI International during the working lunch. First, in 2014, the ERS requested that the National Academies of Sciences, Engineering, and Medicine convene a workshop that looked at the Food Availability and the Loss-Adjusted Food Availability (LAFA)

Examples include the goals embodied in SDG 12.3, the Food Waste Resolution developed by the Consumer Goods Forum, and companies' own targets. Establishing the scope of what is measured should be based on the foundation of a common language.

. Because no single method will work for all countries, three approaches are being refined and tested to provide data for the index: • Modeling, which provides acceptable data quality and is feasible for most countries, would subtract consumption from supply using widely available collected data.

It is expensive and difficult to collect nationally representative data on underlying loss conversion factors, and this underscores the need to prioritize research efforts. Another participant asked about the need for a common definition of food loss and waste.
