Abstract

The growing burden of food losses has intensified the need for reliable and comparable data. This study extends the application of lean manufacturing practices and uses Value Stream Mapping (VSM) analysis with the Food Loss and Waste (FLW) Accounting and Reporting Standard to identify hotspots and analyze the magnitude of both food and nutritional losses in the food value chain. A case study on the dairy value chain in Uganda is utilized to understand the production configuration (primary production, processing and distribution). Through linking hotspots where food loss in milk production takes place to specific salient reasons, this case provides an estimation of the magnitude of losses occurring in yogurt and UHT milk production lines. Findings reaffirm the processing stage as a principle hotspot for discarding yogurt as well as UHT milk products. Throughout processing, from start to finish, food losses at chain level are estimated to be in the magnitude of up to 14%. This also translates to a substantial nutritional value disappearing from the food system, which compromises the ability of people to meet their nutrient recommendations. The case study represents a pragmatic assessment that combines the mapping advantages of VSM with accounting and reporting guidelines of FLW Accounting and Reporting Standard to contribute to a detailed assessment of food and nutritional losses. Thereby, reinforcing initiation of evidence-based and targeted reduction strategies along food supply chains.
