This document discusses the design and implementation of a Social and Behavior Change Communication (SBCC) strategy to promote nutrition and hygiene practices as part of an agricultural intervention in Sierra Leone. It describes how SBCC was used to influence behaviors related to fish consumption, production, and hygiene along the fish value chain. A five-step process was used: 1) defining problems, 2) framing with theory, 3) designing materials with partners, 4) implementing and monitoring activities, and 5) evaluating objectives. The strategy targeted multiple audiences at national, community, and household levels using various communication channels and materials.
