The revolution of the United States agriculture amid increasing climatic, technological and socioeconomic change has elevated the importance of effective communication and extension systems as central method in sustaining innovation and resilience. Traditional top-down dissemination models rooted in early models of Land-Grant and Cooperative Extension systems are becoming less sufficient in addressing the complexity of contemporary farming systems. This narrative review synthesizes recent evidence (2020-2025) on the emergence of digital innovation-, participatory learning-, and resilience-based communication and extension strategies in the U.S. Drawing on interdisciplinary scholarship and policy frameworks, including federal extension modernization and climate-related initiatives, the review recognizes four convergent trends: the digitalization of agricultural knowledge, the revitalization of participatory and co-learning methods, the integration of communication in resilience frameworks, and the development of hybrid, policy-aligned communication ecosystems. Collectively, these developments shift from linear information transfer toward a more adaptive and networked system of knowledge co-production. Despite significant progress, persistent issues remain such as digital inequities, institutional fragmentation, limited evaluation of resilience outcomes, and unresolved ethical concerns related to data. This review concludes that communication and extension should be conceptualized as underlying infrastructures of agricultural resilience, connecting research, policy, and practice through dynamic, inclusive, and evidence-based interaction. Advancing U.S. agriculture requires a more participatory and flexible environment that integrates emerging technologies with collaborative decision-making.
