This deliverable (D1.1) presents the FLWPR actions database, a foundational component of Task 1.1 designed to establish a unified and openly accessible evaluation framework for quantifying the environmental, economic, and social impacts of food loss and waste prevention and reduction (FLWPR) strategies. The primary aim is to develop a scientifically robust ontology that standardizes heterogeneous data from disparate sources into a consistent, parameterized inventory. Positioned as the conceptual and technical backbone for the Action Tracker Tool (WP4, D4.1), this deliverable ensures that automatically retrieved records are semantically aligned with expert-validated taxonomies. Conclusions from this phase indicate that the database has reached the minimum data density required for reliable inventory modeling and future sustainability simulations. However, significant limitations persist regarding data sparsity in public reports, particularly the frequent absence of disclosed Life Cycle Inventories (LCI) and granular socio-economic variables like consumer demographic data. To address these gaps, it is recommended that subsequent project phases utilize regional proxies and secondary data sources for parameter estimation. Furthermore, a "human-in-the-loop" validation protocol should be maintained, prioritizing the manual audit of actions with low confidence scores to ensure the long-term credibility and reproducibility of the generated impact forecasts.
