The human dimension of weed management is most evident when farmers make decisions contrary to science-based recommendations. Why do farmers resist adopting practices that will delay herbicide resistance, or seem to ignore new weed species or biotypes until it is too late? Weed scientists for the most part have ignored such questions or considered them beyond their domain and expertise, continuing to focus instead on fundamental weed science and technology. Recent pressing concerns about widespread failure of herbicide-based weed management and acceptability of emerging technologies necessitates a closer look at farmer decision making and the role of weed scientists in that process. Here we present a circular risk-analysis framework characterized by regular interaction with and input from farmers to inform both research and on-farm risk-management decisions. The framework utilizes mental models to probe the deeply held beliefs of farmers regarding weeds and weed management. A mental model is a complex, often hidden web of perceptions and attitudes that govern how we understand and respond to the world. One's mental model may limit ability to develop new insights and adopt new ways of management, and is best assessed through structured, open-ended interviews that enable the investigator to exhaust the subjects inherent to a particular risk. Our assessment of farmer mental models demonstrated the fundamental attribution error whereby farmers attributed problems with weed management primarily to factors outside of their control, such as uncontrolled weed growth on neighboring properties and environmental factors. Farmers also identified specific processes that contribute to weed problems that were not identified by experts; specifically, the importance of floods and faulty herbicide applications in the spread of weeds. Conventional farmers expressed an overwhelming preference for controlling weeds with herbicides, a preference that was reinforced by their extreme dislike for weeds. These preferences reflect a typical inverse relationship between perceived risk and benefit, where an activity or entity we perceive as beneficial is by default perceived as low risk. This preference diminishes the ability of farmers to appreciate the risks associated with overreliance on herbicides. Likewise, conventional farmers saw great risk and little benefit in preventive measures for weed control. We expect that thorough two-way communication and a deeper understanding of farmer belief systems will facilitate the development of audience-specific outreach programs with an enhanced probability of affecting better weed management decisions.

Organic farmers throughout Austria were asked in 1999 if, once the first agri-environmental program (ÖPUL) ends, they intended to commit themselves to a further five-year period of organic farming. The study presented here addresses those farmers who expressed in the survey the intention to end their participation in organic farming under ÖPUL, or who were undecided at that time. The aim was to compare and analyze the intended behavior with actual behavior. The research was based on material from, and analyses of, the 1999 survey and the survey conducted in 2002. Additional information regarding the reasons for abandoning (or continuing) organic farming and the decision-making process itself was collected through a series of telephone interviews in 2004. The comparison revealed a connection between actual behavior and the intentions expressed in the 1999 survey. However, there were no clear differences in terms of the reasons given in 1999 for potentially discontinuing with organic farming between those farms that remained organic and those that reverted to conventional farming methods. There were differences between those reasons given in the 1999 survey for potentially leaving organic agriculture and the reasons that determined the actual decision, as cited in telephone interviews in 2004. In the 1999 survey, economic issues were the main reasons for potentially ceasing to farm organically. When it came to the actual decision, problems concerning organic guidelines and inspections were more prominent. The environmental attitudes and the social embedding of the farmers within organic agriculture played a decisive role on those enterprises that chose to continue farming organically. The analysis indicates that the presence of a successor is also a stabilizing factor for organic farming.
