Abstract Systems‐level approaches are required for addressing the world's major challenges at the food–energy–water nexus. Taking on complex issues, such as rising food insecurity, malnutrition, and food waste, concomitant with unprecedented levels of stress on environmental systems, will necessitate that future scholars and decision makers be prepared through transdisciplinary student training. However, in higher education, students tend to be siloed within their discipline. In this study, we present a case for the development of transdisciplinary graduate student training based on an inter‐institutional and fully remote group of graduate students who assembled during the COVID‐19 pandemic to address the issue of food waste. We use our wide‐ranging disciplinary backgrounds, high‐performance transdisciplinary team training, and stakeholder feedback to develop and conduct a weeklong social media campaign to share educational resources for reducing household food waste. This work offers valuable lessons learned through the student's lens to those seeking to create or improve future transdisciplinary training methods for tackling food waste and other global grand challenges. Key insights from this process include the importance of accountability and open communication when conducting collaborative teamwork, the utility of various mobile and online tools for effectively facilitating remote group work, and the vital role of transdisciplinarity in devising creative solutions. 

Wicked problems are inherent in food–energy–water systems (FEWS) due to the complexity and interconnectedness of these systems, and addressing these challenges necessitates the involvement of the diverse stakeholders in FEWS. However, successful stakeholder engagement requires a strong understanding of the relationships between stakeholders and the specific wicked problem. To better account for these relationships, we adapted a means, motive, and opportunity (MMO) framework to develop a method of stakeholder analysis that evaluates the agency of stakeholders related to a wicked problem in FEWS. This method involves two key components: (1) identification of a challenge at the FEWS nexus and (2) evaluation of stakeholder agency related to the challenge using the dimensions of MMO. This approach provides a method for understanding the characteristics of stakeholders in FEWS and provides information that could be used to inform stakeholder engagement in efforts to address wicked problems at the FEWS nexus. In this article, we present the stakeholder analysis method and describe an example application of the MMO method by examining stakeholder agency related to the adoption of improved swine waste management technology in North Carolina, USA. 

Understanding sustainable livestock production requires consideration of both qualitative and quantitative factors in a temporal and/or spatial frame. This study adapted Qualitative Comparative Analysis (QCA) to relate conditions of social, economic, and governance factors to changes in livestock inventory across several counties and over time. This paper presents an approach that (1) identified factors with the potential to relate to a change in livestock inventory and (2) analyzed commonalities within these factors related to changes spatially and temporally. This paper illustrates the approach and results when applied to five counties in eastern South Dakota. The specific response variables were periods of increasing, no change, or decreasing beef cattle, dairy cattle, and swine inventories in the specific counties for five-year census periods between 1992 and 2017. In the spatial analysis of counties, stable beef inventories and decreasing dairy inventories related to counties with increasing gross domestic products. The presence of specific social communities related to increases in county swine inventories. In the temporal analysis of census periods, local governance and economic factors, particularly market price influences, were more prevalent. Swine inventory showed a stronger link to cash crop markets than to livestock markets, whereas cattle market price increases associated with stable inventories for all animal types. Local governance tools had mixed effects for the different animal types across space and time. The factors and analysis results are context-specific. However, the process considers the various socio-economic processes in livestock production and community development applicable to agricultural sustainability questions in the Midwest and beyond.
