Communication with farmers about climate change has proven to be difficult, with relatively low acceptance of anthropogenic climate change or the idea that climate change will negatively affect agriculture. Many farmers have been impervious to climate change communications because of the nature of farming, their worldviews, and the controversies about climate change in the media. Segmentation studies from the agriculture and natural resource management literatures provide evidence of homogeneous farmer groups internationally with respect to climate change attitudes and behaviors in a farming context. Understanding these segments—including their values, beliefs, and behaviors—is important for developing tailored and targeted communications approaches. Based on understanding of commonly observed farmer segments, it is possible to tailor communication strategies to better engage with segments of concern, including which message to use, appropriate sources, as well as alternative communication techniques based on participatory approaches and use of the arts. For certain segments, discussion about human-induced climate change should be avoided given that it is contentious and not critical for how farmers should respond to climate change. Theoretical frameworks from psychology and marketing—such as the theory of planned behavior, the attitude-to-behavior process model, the motivation and opportunity and determinants (MODE) model, motivation to avoid harm, and the elaboration likelihood model—can also be used to inform the design of communication strategies for engaging with farmers. However, a careful analysis of farmer segments, their worldviews, their beliefs, and their position in the consumer decision-making process suggests that the recommendations from these theoretical models should not be implemented uniformly across farmer segments. Rather, the various theoretical models provide a number of strategies that need to be selectively applied based on knowledge of the target segment. While use of theory and understanding of segments will help to improve communications with farmers, it is apparent that changing the beliefs of farmers in some segments about the need to respond to climate change will require more than simply increasing the quantity or quality of communications. Engaging farmers in these segments requires a much richer information set and a much greater effort to show farmers how they should be responding to climate variability and change using practical demonstrations and participatory approaches.

Diffusion is the process through which new ideas, technologies, products, or processes are spread through communication among members of a social system via communication channels over time. Diffusion is a specialized form of communication that focuses on disseminating information about new ideas, products, technologies, services, or regulations. It is an especially important form of communication because it promotes social progress in the evaluation and adoption of important new ideas to address social issues. Diffusion helps to reduce uncertainty about how to address difficult issues and provides direction for achieving social goals. A large body of research has been conducted from many disciplines on the diffusion of innovations since the original publication of Everett M. Rogers’ seminal book The Diffusion of Innovations in 1962, which is now in its fifth edition (2003). In this book, he introduced the Diffusion of Innovations (DOI) model, which describes a general process of adopting new ideas across multiple populations, cultures, and applications. This research has examined innovations in fields such as agriculture, engineering, sales, education, architecture, technology, public policy, and health care, and has been applied to a range of different issues, such as the adoption of new technologies, consumer purchasing behaviors, and public support for political issues and candidates, but has been especially influential in guiding strategic health promotion. The DOI model has contributed to a greater understanding of health behavior change, including adoption of health promotion recommendations. The model has led to a broad scope of practical applications for promoting public health.
