The Iowa Nutrient Reduction Strategy aims to reduce nutrient loads in waterways from nonpoint sources such as farm fields. Farmers’ voluntary adoption of soil and water conservation practices is crucial for achieving NRS goals. Although the Iowa NRS has been active since 2013, farmer participation and net pollutant reductions have been insufficient. Therefore, continued efforts to understand the motivations and barriers that underlie farmers’ conservation actions in a comprehensive and integrated manner are needed to improve outreach strategies, and research examining (...) the relationships among factors such as farmers’ self-efficacy, motivations, perceived economic pressure, and soil and water conservation practices adoption in row crop production systems is needed to inform that outreach. This research employed social cognitive theory and previous research around the conceptual category of “motivations” to inform the study of relationships between the dynamic precursors and later modifiers of farmers’ adoption of in-field nutrient management Best Management Practices. Data are from the 2014–2016 Iowa Farm and Rural Life Poll. Self-efficacy, collective efficacy, stewardship motivation, crop insurance, perceived economic pressure, age, and crop acres were important predictors of adoption. This research provides innovative insights for policymaking, extension agencies, and other researchers concerning the adoption of nutrient management practices. (shrink)

Farmers’ willingness and ability to adapt to climate change are in part influenced by their social networks and sources of information. Drawing on assemblage theory and social network analysis in a novel way, this study explores the influence of Oregonian small farmers’ social and informational networks on their beliefs about and responses to climate change. The use of assemblage theory, which focuses on many disparate elements as they co-function in a space, allows for multiple entities within farmers’ networks and the (...) ways they interact to be examined, while the use of social network analysis highlights broader patterns in the structure and composition of farmers’ networks. Theoretically, this study brings these two distinct yet similar bodies of theory and methodologies together for the first time to expand the utility of both fields and explore farmers’ networks in a novel way. Results indicate that small farmers’ connections to other farmers and media in their networks are influencing their beliefs about climate change, while their responses are influenced by their ties to various agricultural and climatological information sources, as well as other nearby farmers. Finally, while farmers’ ties to other farmers are largely limited to those nearby, certain central individuals and entities, particularly beginning farmers, can act as bridges linking distinct groups of farmers. An understanding of these networks can be used to better disseminate critical information, such as forecasts and adaptation strategies, to help farmers adapt. (shrink)
