20 pgs., Twelve U.S. states were tasked with developing nutrient reduction strategies to help address hypoxia in the Gulf of Mexico. To better understand the kinds of messages different stakeholders in these states are likely to encounter about such strategies, we conducted a content analysis focused on the Iowa Nutrient Reduction Strategy (INRS). We examined 483 articles in two agricultural and two non-agricultural news outlets. We found that agricultural news outlets more often led with agricultural themes and more often used agricultural representatives as sources. The non-agricultural news outlets more often quoted representatives of environmental groups. News articles infrequently led with science or health themes. The volume of coverage over time in three of the four news outlets appeared followed similar issue attention cycles. Differences among the outlets may lead to differences in stakeholders’ knowledge or views about the INRS and conservation, posing challenges to consensus-building.
10 pages, The study sought to explore the extent to which agricultural policies in sub-Saharan Africa (SSA)
countries incorporate Indigenous Knowledge (IK) and its impact on the efforts to document and share
agricultural IK through communication efforts. A qualitative content analysis of policy documents from seven SSA countries and eight key informant interviews with knowledge management officers from the seven countries was conducted. Purposive sampling was used to select the countries, determine
documents examined, and for the selection of key informants for the interviews. The results revealed that IK was not included in several SSA countries’ governmental agricultural policies. Activities aimed at capturing, documentation and sharing IK in SSA countries were not found despite the presence of evidence of its importance to agricultural research and development. These results provide insights on the need for researchers, communicators, educators, and decision-makers to consider incorporating IK into policy associated with agricultural information dissemination to improve technology generation and adoption
16pgs, Humanity's growing appetites for food and energy are placing unprecedented yield targets on our lands. Chasing those ever-expanding land intensification targets gave rise to monocultures and sharpened the divide between food and energy production groups. Here, we argue that this does not have to be a zero-sum game if food and energy can be co-generated in the same land. Co-generation can lead to sustainable intensification but requires a paradigm shift in the way we manage our resources, particularly light. Using an extended model of plant photosynthesis and transpiration, we demonstrate how plants react to different incident light spectra and show that manipulating light could be effective for boosting land and water efficiencies, thus potentially improving soil health. This knowledge can possibly unlock the real potential of promising modern agricultural technologies that target optimization of light allocations such as agrivoltaics. This study suggests that the blue part of the light spectrum is less efficient in terms of carbon assimilation and water use and could be more effectively used to produce solar energy, while the red part could efficiently produce biomass. A sensitivity analysis to the most important crop and environmental variables (irradiance, air temperature, humidity, and CO2 concentration) shows that plant response to different light treatments is sensitive to environmental boundary conditions and is species-specific. Therefore, further research is necessary to assess which crops and climates are more suitable to optimize the proposed food-water-energy nexus.
25 pages, Using linked data from multiple years of the U.S. Census of Agriculture, this study identifies farm and operator characteristics associated with beginning farm survival, growth, and success. Success is defined as continuing in business for 5 years without a decline in farm real estate asset value. The results indicate which types of beginning farms and farmers are likely to survive and grow—information which could be useful in targeting program resources. By identifying policy-amenable variables that correlate with both farm survival and business expansion, the results also suggest possible mechanisms for increasing the success of beginning farms.
19 pages, In today’s globalized world, educators and employers generally agree on the necessity for undergraduate agricultural [ag] students to develop a sound understanding of global ag issues and policy. Because of this, many U.S. universities have promoted internationalizing curriculum and increased international study abroad experiences. However, few studies have examined the impact of international experiences on students’ knowledge and attitudes about international ag issues and policies. This study bridges this gap by identifying the relationship between student knowledge and attitude toward international ag issues and U.S. ag policy, and how international experience and demographic variables play a role in that relationship. Adapted from previous literature, an online survey was developed in 2019 among 196 undergraduate students in ag and non-ag fields to measure student knowledge (global aptitude assessment) and student attitude (attitude index score) towards the importance of global agricultural issues and policy. Results concluded that undergraduate students held a low level of knowledge about global ag issues and policy; in fact, ag students held lower average knowledge scores than non-agricultural students. This emphasizes the urgency for administrators to intentionally design and reevaluate our current curriculum to meet these knowledge gaps. Additionally, study abroad experiences did not contribute to students’ knowledge nor attitudes. The authors discuss several possibilities for such results and highlight the call to similarly reevaluate our study abroad curriculum to be more intentional in impacting student knowledge in global ag food systems and acknowledge differences in policy, getting students excited and interested in the global market.
15pgs, Agriculture is crucial in catering to the increasing demand for food and employment. Thus, adoption of novel technologies is important. Many scientists have developed different theories and models explaining the process of behavioral change relevant to adoption. They are either completely different, similar, or improvements of previously developed models. Therefore, compilation and summarization of these theories and models will support future studies and researchers. Thus, an analysis of literature on technology adoption was conducted. The review was prepared based on literature from various sources spanning around 50 years. The theories and models identified by different studies were compiled and analyzed in this review paper. Many theories and models in agricultural technology adoption such as transtheoretical model, theory of reasoned action, theory of interpersonal behavior, model for innovation-decision process, different versions of technology acceptance model, theory of planned behavior, theory of diffusion of innovation, task-technology fit, technology readiness, unified theory of acceptance and use of technology, expectancy livelihood model, social cognitive theory, and perceived characteristics of innovating theory were compiled. Each theory and model has its own uniqueness, which had explained different aspects of technology adoption process and factors determining the behavioral change. These theories and models included affecting factors such as technological, personal, social, and economical factors. In conclusion, it can be stated that, rather than having a single theory or a model, an integrated and amalgamated form will be more explanatory for technology adoption.
6 pages, In this time of information overload, successfully engaging farmers with compelling outreach materials is a major challenge for conservation programs and related research projects. One potential approach is targeting information to the recipient, e.g., local rather than regional soil and water conditions, when sending messages to farmers. Targeted information may increase engagement by making materials stand out as more relevant and useful; conversely, it may decrease engagement by making farmers wary of the program and how it is using the information. We tested the effect of targeted information on farmer engagement using a large, randomized controlled trial in Iowa. In partnership with Iowa State University, we sent 2,996 farmers a single mailing with information about erosion at the local watershed (targeted) or state (control) level and measured their responses to a two-minute survey. We found that targeted information increased relative response rates by 20%, from 13.8% to 16.4%. This level of increase is meaningful for practitioners, as well as statistically significant. Our findings show that targeted information can be an important tool for practitioners and researchers seeking to better connect with farmers who are inundated with marketing mail.
14 pages, As agricultural conservation priorities evolve to address new complex social-ecological problems and emerging social priorities, new conservation incentive program participation and success can be enhanced by incorporating local stakeholder preferences into program design. Our research explores how farmers incorporate ecosystem services into management decisions, their willingness to participate in payment for ecosystem services programs, and factors beyond compensation level that would influence participation. We conducted three focus groups with 24 participants between January of 2019 and May of 2019 in Vermont. Our study revealed that a strong, intrinsic stewardship ethic motivates farmers to enhance ecosystem service provisioning from their farms, though financial pressures often limit decision-making. These results suggest that programs with sufficient levels of payment may attract participation, at least among some types of farmers, to enhance ecosystem services from farms in Vermont. However, farmers may be deterred from participating by perceived unfairness and distrust of the government based on previous experiences with regulations and conservation incentive structures. Farmers also expressed distrust of information about ecosystem services supply that conflicts with their perceptions of agroecosystem functioning, unless delivered by trusted individuals from the extension system. The delivery of context-specific information on how management changes impact ecosystem service performance from trusted sources could enhance farmers’ decisions, and would aptly complement payments. Additionally, farmers expressed a desire to see a program that both achieves additionality and rewards farms who have been stewards, goals that are potentially at odds. Our findings offer important insights for policy makers and program administrators who need to understand factors that will influence farmers’ willingness to participate in payment for ecosystem service programs and other conservation practice adoption initiatives, in Vermont and elsewhere.
