Item The global food environment transition based on the socio-demographic index(Elsevier BV, 2022-06) Downs, Shauna M.; Ahmed, Selena; Warne, Teresa; Fanzo, Jessica; Loucks, KellyFood environments are a critical point for reorienting the food system towards sustainable diets, as they are directly where consumers make decisions about which foods to acquire. Using global data, we examined shifts in food environments, and the availability, affordability, convenience, and quality of foods within them, over time on the basis of socio-demographic index (SDI) country groupings. Our findings provide evidence of a food environment transition where built environments have shifted from traditional to modern retail outlets between 2005 and 2019 and the availability and affordability of nutrient-rich foods has increased alongside growing sales of ultra-processed and ready-to-eat foods. This transition has implications for the identification of policy and program levers for promoting healthy and sustainable diets and reducing malnutrition globally.Item The Influence of the COVID-19 Pandemic on the Food Supply in the Emergency Food System: A Case Study at 2 Food Pantries(Oxford Academic, 2021-10) Larison, LeeAnna; Shanks, Carmen Byker; Webber, Eliza; Routh, Brianna; Ahmed, SelenaBackground. The onset of the coronavirus disease 2019 (COVID-19) pandemic increased demand for emergency food assistance and has caused operational shifts in the emergency food system. Objective. This research explored how the initial phase of the COVID-19 pandemic influenced the food supply of 2 food pantries. Methods. A case study approach was applied to collect data during the initial phase of the COVID-19 pandemic. Food supply data were collected weekly at 2 food pantries in southwest Montana for 17 wk in 2020. Surveys and interviews were conducted with food pantry clients and staff, respectively. Descriptive statistics and inferential statistics were applied to analyze quantitative data. Food supply data were analyzed using the Healthy Eating Index (HEI)-2015, NOVA system, and Unprocessed Pantry Project (UP3) Framework. Thematic analysis was applied to qualitative data. Results. The food boxes collected between the 2 food pantries (n = 43) had a mean (± SD) total HEI-2015 score of 76.41 ± 7.37 out of a possible score of 100. According to both the NOVA and the UP3 Framework, 23.4% of the total food distributed was ultra processed food. Of the food distributed, 50.0% and 48.3% was fresh, unprocessed food according to NOVA and UP3 Frameworks, respectively. From staff interviews, 3 themes arose that describe the food pantry operations that experienced change during the COVID-19 pandemic, including food procurement, distribution preparation, and food distribution. Nine supporting subthemes describing the causes and consequences of the operational themes were identified. Staff perceived that the nutrient quality of the food boxes increased from food distributed previously to the COVID-19 pandemic, whereas over one-third (39.4%) of food pantry clients who responded to surveys preferred the food box model. Conclusions. The COVID-19 pandemic has caused enormous operational challenges within food pantries. Food pantries overcame these challenges by swiftly and effectively altering operations so as to continue to distribute nutritious food boxes to pantry clients.Item Climate Change and Coffee Quality: Systematic Review on the Effects of Environmental and Management Variation on Secondary Metabolites and Sensory Attributes of Coffea arabica and Coffea canephora(Frontiers, 2021-10) Ahmed, Selena; Brinkley, Sarah; Smith, Erin; Sela, Ariella; Theisen, Mitchell; Thibodeau, Cyrena; Warned, Teresa; Van Dusen, Natalie; Guiliano, Peter; Ionescu, Kim Elena; Cash, Sean B.Climate change is impacting crop performance and agricultural systems around the world with implications for farmers and consumers. We carried out a systematic review to synthesize evidence regarding the effects of environmental factors associated with climate change and management conditions associated with climate adaptation on the crop quality of a culturally-relevant perennial crop, coffee (Coffea arabica and Coffea canephora). Seventy-three articles were identified that addressed the study's research question including 42 articles on environmental factors, 20 articles on management conditions, and 11 articles on both. While variation was found between studies, findings highlight that coffee quality is vulnerable to changes in light exposure, altitude, water stress, temperature, carbon dioxide, and nutrient management. Both increases as well as decreases were found in secondary metabolites and sensory attributes that determine coffee quality in response to shifts in environmental and management conditions. The most consistent evidence identified through this systematic review includes the following two trends: (1) increased altitude is associated with improved sensory attributes of coffee and; (2) increased light exposure is associated with decreased sensory attributes of coffee. Research gaps were found regarding the effects of shifts in carbon dioxide, water stress, and temperature on the directionality (increase, decrease, or non-linear) of coffee quality and how this varies with location, elevation, and management conditions. This systematic review further identified the following research needs: (1) long-term studies that examine the interactive effects of multiple environmental factors and management conditions on coffee quality; (2) studies that examine the interaction between sensory attributes and secondary metabolites that determine coffee quality and; (3) studies on the feasibility of various climate-adaptation strategies for mitigating the effects of climate change on coffee quality. Evidence-based innovations are needed to mitigate climate impacts on coffee quality toward enhanced sustainability and resilience of the coffee sector from farm to cup.Item Perceptions and Responses of Diversified Farm Producers in the Northern Great Plains to the Early Stage of the COVID-19 Pandemic(Frontiers Media SA, 2022-02) Ebel, Roland; Ahmed, Selena; Warne, Teresa; Moxley, Alexandria; Grimberg, Irene; Jarchow, Meghann; Menalled, Fabian D.The initial months of the COVID-19 pandemic revealed unique vulnerabilities of the global food system with notable societal consequences, calling for the need to implement resilience strategies to support food security for all. The objective of this study was to elicit perceptions, experiences, and responses of producers of diversified farms in the Northern Great Plains of the United States to the early stage of the COVID-19 pandemic toward identifying factors for strengthening the resilience of agricultural production for supporting livelihoods and food security. Between May and August 2020, a cross-sectional online survey was administered to the emerging community of diversified farm managers in two rural U.S. states, Montana and South Dakota (n = 53), where monocropping and extensive livestock production are prevalent. About two-thirds of surveyed producers (68%) reported that they did not change their farming practices in response to the pandemic up until the survey period in Summer 2020. Almost three-quarters of producers (73%) indicated that access to commodities, farm inputs, and farm labor was not a concern for them during the early stage of the pandemic. Most surveyed producers (88%) were not concerned about their household food security and expressed confidence regarding a long-term increase in the demand for local food. However, almost half of surveyed producers (47%) reported that their anxiety increased because of the pandemic. Findings further highlight that small farms implemented a greater number of practices for enhancing ecological self-regulation while depending strongly on off-farm income compared to larger farms that were economically more autonomous. This study points to the promise of farm system diversification in strengthening the resilience of agricultural systems. We conclude by outlining pathways for increasing diversity on farms toward supporting food security during extreme food system shocks.Item Perceptions and Responses of Diversified Farm Producers in the Northern Great Plains to the Early Stage of the COVID-19 Pandemic(Frontiers Media SA, 2022-02) Ebel, Roland; Ahmed, Selena; Warne, Teresa; Moxley, Alexandria; Grimberg, Irene; Jarchow, Meghann; Menalled, Fabian D.The initial months of the COVID-19 pandemic revealed unique vulnerabilities of the global food system with notable societal consequences, calling for the need to implement resilience strategies to support food security for all.

As a relatively young field, there is a need for clearly articulated learning outcomes (LOs) for SFS education to define student learning through degree programs, design new programs, and evaluate and modify existing programs. New and established SFS programs are often fragmented over multiple academic departments which impedes the development of a coherent and holistic curriculum for approaching the complexity of food topics. Here, we address these needs through the co-creation of adaptable LOs for Baccalaureate degree-level SFS programs which are aligned to a SFS Signature Pedagogy and based on outcomes-based education toward contributing to a solid conceptual basis for SFS education. The SFS Signature Pedagogy is a framework that can be applied to develop students' systemic capacities, including holistic, and pluralistic ways of understanding sustainability challenges, multi-, inter- and trans-disciplinarity, experiential learning, and collective action projects. Our co-design of LOs was based on qualitative content analysis of existing LOs of established SFS programs, a cross-sectional survey with SFS educators and refinement of LOs from feedback in an expert panel. This process resulted in the eight adaptable LOs: (1) systems thinking, (2) critical reflection, (3) diverse ways of knowing, (4) practical application, (5) multi-context communication, (6) teamwork, (7) collective action, and, (8) advocacy for SFS. We anticipate the adaptable LOs proposed here to be applicable for diverse student communities and geographic respectively cultural contexts as well as to provide insight for sustainability-related academic programs toward developing professionals equipped with skills and capacities to address complex challenges.Item Food Environment Typology: Advancing an Expanded Definition, Framework, and Methodological Approach for Improved Characterization of Wild, Cultivated, and Built Food Environments toward Sustainable Diets(2020-04) Downs, Shauna M.; Ahmed, Selena; Fanzo, Jessica; Herforth, AnnaThe food environment is a critical place in the food system to implement interventions to support sustainable diets and address the global syndemic of obesity, undernutrition, and climate change, because it contains the total scope of options within which consumers make decisions about which foods to acquire and consume. In this paper, we build on existing definitions of the food environment, and provide an expanded definition that includes the parameter of sustainability properties of foods and beverages, in order to integrate linkages between food environments and sustainable diets. We further provide a graphical representation of the food environment using a socio-ecological framework. Next, we provide a typology with descriptions of the different types of food environments that consumers have access to in low-, middle-, and high-income countries including wild, cultivated, and built food environments. We characterize the availability, affordability, convenience, promotion and quality (previously termed desirability), and sustainability properties of food and beverages for each food environment type. Lastly, we identify a methodological approach with potential objective and subjective tools and metrics for measuring the different properties of various types of food environments. The definition, framework, typology, and methodological toolbox presented here are intended to facilitate scholars and practitioners to identify entry points in the food environment for implementing and evaluating interventions that support sustainable diets for enhancing human and planetary health.Item Farmer and Rancher Perceptions of Climate Change and Their Relationships with Mental Health(2020-04) Howard, Meredith; Ahmed, Selena; Lachapelle, Paul; Shure, Mark B.The impacts of climate change are having negative consequences on agricultural communities in the United States and other regions of the world. More specifically, these impacts are expected to increase in both scale and complexity and will continue to pose challenges both in terms of agricultural production and capacity. The purpose of this study was to understand ranchers’ and farmers’ perceptions of climate change’s impact on their businesses and their mental well-being in a rural U.S. western state. Surveys were administered online and in-person to farmers and ranchers in fall of 2017. Descriptive statistics and correlational tests were conducted to evaluate if climate risk perception was related to levels of mental distress. Open-ended survey questions explored specifically how climate change is impacting mental well-being. The majority of respondents agree that climate change is having an impact on agricultural business, and nearly three quarters of respondents are experiencing moderate to high levels of anxiety when thinking about climate change and its effects on agricultural business. A moderate correlation was observed between climate risk perception and climate-related anxiety. Qualitative data showed the impact of climate change on profitability was perceived as the main cause of distress. This study demonstrates that climate change is generating anxiety and distress for farmers and ranchers. To maximize public health preparedness efforts, interventions are warranted to provide climate adaptation education and therapeutic outreach specific to agricultural workers experiencing economic struggle in the context of climate change.Item Changes in Tea Plant Secondary Metabolite Profiles as a Function of Leafhopper Density and Damage(2020-05) Scott, Eric R.; Li, Xin; Wei, Ji-Peng; Kfoury, Nicole; Morimoto, Joshua; Guo, Ming-Ming; Agyei, Amma; Robbat Jr., Albert; Ahmed, Selena; Cash, Sean B.; Griffin, Timothy S.; Stepp, John R.; Han, Wen-Yen; Orians, Colin M.Insect herbivores have dramatic effects on the chemical composition of plants. Many of these induced metabolites contribute to the quality (e.g., flavor, human health benefits) of specialty crops such as the tea plant (Camellia sinensis). Induced chemical changes are often studied by comparing plants damaged and undamaged by herbivores. However, when herbivory is quantitative, the relationship between herbivore pressure and induction can be linearly or non-linearly density dependent or density independent, and induction may only occur after some threshold of herbivory. The shape of this relationship can vary among metabolites within plants. The tea green leafhopper (Empoasca onukii) can be a widespread pest on tea, but some tea farmers take advantage of leafhopper-induced metabolites in order to produce high-quality “bug-bitten” teas such as Eastern Beauty oolong. To understand the effects of increasing leafhopper density on tea metabolites important for quality, we conducted a manipulative experiment exposing tea plants to feeding by a range of E. onukii densities. After E. onukii feeding, we measured volatile and non-volatile metabolites, and quantified percent damaged leaf area from scanned leaf images. E. onukii density had a highly significant effect on volatile production, while the effect of leaf damage was only marginally significant. The volatiles most responsive to leafhopper density were mainly terpenes that increased in concentration monotonically with density, while the volatiles most responsive to leaf damage were primarily fatty acid derivatives and volatile phenylpropanoids/benzenoids. In contrast, damage (percent leaf area damaged), but not leafhopper density, significantly reduced total polyphenols, epigallocatechin gallate (EGCG), and theobromine concentrations in a dose-dependent manner. The shape of induced responses varied among metabolites with some changing linearly with herbivore pressure and some responding only after a threshold in herbivore pressure with a threshold around 0.6 insects/leaf being common. This study illustrates the importance of measuring a diversity of metabolites over a range of herbivory to fully understand the effects of herbivores on induced metabolites. Our study also shows that any increases in leafhopper density associated with climate warming, could have dramatic effects on secondary metabolites and tea quality.Item Intended and Unintended Consequences of a Community-Based Fresh Fruit and Vegetable Dietary Intervention on the Flathead Reservation of the Confederated Salish and Kootenai Tribes(2020-08) Ahmed, Selena; Dupuis, Virgil; Tyron, Michael; Running Crane, MaryAnn; Gavin, Teresa; Pierre, Micheal; Byker Shanks, CarmenTribal communities in the United States face disparities to accessing healthy foods including high-quality produce. A six-week fresh fruit and vegetable (FV) dietary intervention, Eat Fresh, was co-designed with a Community Advisory Board of local food and nutrition stakeholders on the Flathead Reservation of the Confederated Salish and Kootenai Tribes in Montana. Eat Fresh was implemented as a pilot study with low-income participants (n = 19) enrolled in the Food Distribution Program on Indian Reservations toward improving dietary quality and perceptions of well-being. We evaluated Eat Fresh at pre- and post-intervention on the basis on food procurement practices, dietary quality using the Healthy Eating Index (HEI), Body Mass Index (BMI), blood pressure, and participant perceptions of health. Participants reported consuming a greater number of types of FVs daily during the intervention (p < 0.005 for fruits and p > 0.19 for vegetables). Overall, participants found Eat Fresh moderately challenging to adhere to with the main barriers being access to ingredients in recipes (39.51% of responses), time constraints to cook (35.80%), and lack of financial resources (33.33%). Dietary quality improved during the intervention from a mean HEI score of 48.82 (± 11.88) out of 100–56.92 (± 11.88; (p > 0.12). HEI scores for fruit consumption significantly increased (p < 0.05) from 1.69 (out of 5 points) during the pre-intervention to 2.96 during the post-intervention. BMI and blood pressure increased for several participants, highlighting an unintended consequence. Most participants responded that FV consumption made them feel either very good (51.16%) or good about their health (43.02%) with the majority (83%) perceiving an improvement in energy. Findings of this pilot study highlight both intended and unintended consequences of a dietary intervention that provide lessons in co-designing community-based programs.
