This study assesses the effectiveness of two online courses tailored for farmers and ranchers in California, with a particular focus on the role of farmer-to-farmer pedagogies. Utilizing live sessions, a social-learning platform, and multimedia content, we draw insights from engagement metrics, lesson and end-of-course survey evaluations, and course outcomes. Key findings highlight the pivotal role of peer interactions, featuring farmers and completion incentives. Based on the findings, we advocate for the integration of farmer-to-farmer education methods within online learning environments to cultivate regional learning networks and promote the timely exchange and cocreation of agricultural knowledge amid environmental change.
