Deliverable 1.1 aims at developing a robust, consistent and science-based methodological framework in order to identify agri-food value chain (VC) characteristics and business models (BM) that promote price fairness and thus, a fair revenue distribution along the food supply chain, especially for farmers. Three fairness criteria are considered for evaluating the VCs and BMs, namely: Distributive fairness; Procedural fairness; Interactional fairness. The content of the deliverable is a valuable conceptual and methodological instrument for the rest of the project development.
