Item Diversity and use of medicinal plants for soup making in traditional diets of the Hakka in West Fujian, China(2019-11) Luo, Binsheng; Li, Feifei; Ahmed, Selena; Long, ChunlinBackground Wild edible and medicinal plants were an important component of traditional diets and continue to contribute to food security, nutrition, and health in many communities globally. For example, the preparation and consumption of soup made of medicinal plants for promoting health and preventing disease are a key component of the traditional diets of the Hakka socio-linguistic group of China’s West Fujian Province. As environmental and socio-economic factors drive the shift away from traditional diets, there is a need for ethnobotanical documentation of the diversity of wild edible and medicinal plants as well as associated knowledge and practices. Method Ethnobotanical surveys were conducted in Hakka communities in West Fujian Province between 2017 and 2018 to document plants used in medicinal soups as well as associated traditional ecological knowledge, practices, and conservation status. Surveys included semi-structural interviews, key informant interviews, participatory rural appraisal, and focus group discussions. Quantitative indices, including cultural food significance index (CFSI) and relative frequency of citation (RFC), were calculated to evaluate the importance of documented plants to Hakka communities. The species with the highest CFSI and RFC values were ranked by informants and further evaluated according to their individual properties and growth environment. Results A total of 42 medicinal plant species, belonging to 25 families and 41 genera, were documented for making soup by the Hakka. The Asteraceae botanical family was the most prevalent, and their root or the entire plant is used for soup making. Informants incorporate different ingredients in soups for their flavors as well as medicinal properties on the basis of the local ethnonutrition system. The most prevalent medicinal uses of the documented plants for making soups were used for clearing inner heat (58.1% of the species), treating inflammation (37.2%), and counteracting cold in the body (20.9%). Informants perceived that the medicinal properties of soup-making plants are influenced by the time of harvest, the local environment, and the climate. Conclusion Efforts are needed to preserve the ecological knowledge associated with traditional diets towards supporting both environmental and human well-being in rapidly developing communities experiencing the nutrition transition and biodiversity loss.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.Item Perceptions of food environments and nutrition among residents of the Flathead Indian Reservation(2020-10) Byker Shanks, Carmen; Ahmed, Selena; Dupuis, Virgil; Houghtaling, Bailey; Running Crane, MaryAnn; Tryon, Mike; Pierre, MikeBackground Indigenous food systems have been displaced with the emergence of colonization, industrialization, and cultural, economic, political, and environmental changes. This disruption can be seen in marked health and food environment disparities that contribute to high obesity and diabetes mellitus prevalence among Native American peoples. Methods A Community-Based Participatory Research (CBPR) approach was used to document food environment experiences among residents of the Flathead Reservation in rural Montana. Participants were identified using purposive sampling techniques to participate in a survey and a semi-structured interview. Descriptive statistics helped to describe participant demographics, food access variables, and household food security status. Food environment perceptions were analyzed using the constant comparison method among trained researchers. Results Participants completed surveys (n = 79) and interviews (n = 76). A large number participated in federal nutrition assistance programs. Many self-reported experiencing diet-related chronic diseases. Major themes included the community food environment, dietary norms, and food-health connections. Subthemes were represented by perceptions of food environment transitions and the important role of food in familial life. Further, opportunities and challenges were identified for improving community food environments. Conclusions Perceptions of the food environment were linked to strategies that could be targeted to improve dietary quality along a social-ecological model continuum. There is need for skill-based education that directly addresses the time and monetary constraints that were commonly experienced by residents. Coinciding food environment interventions to promote dietary quality that engage community members, store management, and government policy stakeholders are also needed to reestablish healthy Native American food systems and environments within this community.Item Bamboos for weaving and relevant traditional knowledge in Sansui, Southwest China(2020-10) Luo, Binsheng; Ahmed, Selena; Long, ChunlinBackground Traditional bamboo weaving has been practiced for centuries in Sansui, a county dominated by the Miao people, in Guizhou province of Southwest China. Sansui bamboo weaving represents an intangible cultural heritage as defined by UNESCO, but, like many other traditional handicrafts in China, it has suffered a downfall in this period of rapid development. Sansui bamboo weaving is now experiencing a renaissance due to the joint efforts of the local government, bamboo weaving companies, and individual bamboo weavers. However, what bamboo species have supported the traditional bamboo weaving in Sansui keeps unknown up to now. The traditional knowledge and technology associated with bamboo weaving have not been reported. In addition, the resumption of the local bamboo industry may provide some valuable experiences for other downfallen traditional handicrafts or local communities. Thus, an ethnobotanical study on Sansui bamboo weaving has been carried out. Methods This study mainly used ethnobotanical methods, including key informant interviews and participatory observations. Different stakeholders were selected by applying the snowball method as our key informants including 6 officials, 37 bamboo weavers, and 17 bamboo and bamboo weaving product merchants. We also went into the local weavers’ houses to visit the whole weaving process. The bamboo and dye plant species for bamboo weaving were identified by taxonomists and referring to online databases available. Results Based on field investigations, 17 bamboo species used for weaving were recorded. Different bamboo species were woven for different purposes based on their own characters. Phyllostachys heteroclada is the most popular species locally. Bamboo strips are usually dyed by using Platycarya strobilacea and Rubia cordifolia to be made for different images. In recent years, the size, functions, and materials of local bamboo weaving crafts as well as their market mode have been changed to adapt to new development trends and to cater to the market. In addition, the cooperation among bamboo weavers, bamboo companies, and household workshops has provided great support to the local bamboo industry and to reboot the economy of the local community. Some suggestions for the sustainable economic development of Sansui bamboo weaving and other Chinese traditional handicrafts are proposed. Conclusion In the present study, the bamboo weaving-associated traditional knowledge was collected by means of ethnobotanical methods. The recent renaissance of the bamboo weaving business in Sansui can be attributed both to government support and the innovations of the bamboo weaving industry itself. The developing mode (“Internet + intangible cultural heritage + poverty alleviation”), which combined the internet, poverty alleviation, and intangible cultural heritage, is valid and worth being promoted.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 Ethnobotany and diversity of medicinal plants used by the Buyi in eastern Yunnan, China(2020-10) Xiong, Yong; Sui, Xueyi; Ahmed, Selena; Wang, Zhi; Long, ChunlinThe Buyi are a socio-linguistic group in Yunnan Province of southwest China that have a long history of using medicinal plants as part of their indigenous medical system. Given the limited written documentation of the Buyi indigenous medical system, the objective of this paper is to document the medicinal plants of the Buyi and associated traditional knowledge and transmission. Field research was conducted in four villages in Lubuge Township of Luoping County in Yunnan Province using ethnobotanical methodologies including participatory observation, semi-structured interviews, key informant interviews, and focus group discussions to elicit information on medicinal plants. In total, 120 informants (including 15 key informants who are healers) were interviewed. This study found that a total of 121 medicinal plant species belonging to 64 families are used by the Buyi including by local healers to treat different diseases. Among the medicinal plants recorded in this study, 56 species (46%) have not previously been documented in the scientific literature as having medicinal value, highlighting the pressing need for ethnobotanical documentation in indigenous communities. The most frequently used medicinal part was the leaf (24.9% of documented plants), and the most common preparation method was decoction (62.8% of medicinal). Medicinal plants were mainly used to treat rheumatism (12.4% of plants), trauma and injuries (9.6%). The documented plants are also used for other non-medicinal purposes including food, fodder, fencing, and ornamental. In addition, 35 of the medicinal plants are considered poisonous and are used by local Buyi healers for medicine. The traditional Buyi beliefs and practices associated with the documented medicinal plants likely contributes to their conservation in the environments and around Buyi communities. This study further highlights that ethnomedicinal knowledge of the Buyi is at risk of disappearing due to increased introduction and use of modern medicine in Buyi communities, livelihood changes, rapid modernization, and urbanization. Research, policy, and community programs are urgently needed to conserve the biocultural diversity associated with the Buyi medical system including ethnobotanical knowledge towards supporting both environmental and human wellbeing.Item Variation of Microbiological and Biochemical Profiles of Laowo Dry-Cured Ham, an Indigenous Fermented Food, during Ripening by GC-TOF-MS and UPLC-QTOF-MS(2020-07) Lin, Fengke; Cai, Fei; Luo, Binsheng; Gu, Ronghui; Ahmed, Selena; Long, ChunlinFermented foods have unique microbiota and metabolomic profiles that can support dietary diversity, digestion, and gut health of consumers. Laowo ham (LWH) is an example of an indigenous fermented food from Southwestern China that has cultural, ecological, economic, and health significance to local communities. We carried out ethnobiological surveys coupled with metagenomic and metabolomic analyses using GC-TOF-MS and UPLC-QTOF-MS to elucidate the microbiota and metabolic profiles of LWH samples at different ripening stages. The results from high-throughput sequencing showed a total of 502 bacterial genera in LWH samples with 12 genera of bacteria and 6 genera of fungi identified as dominant groups. This is the first study to our knowledge to report the bacteria of Lentibacillus and Mesorhizobium along with fungi Eremascus and Xerochrysium on a fermented meat product. Findings further revealed that the metabolite profiles among LWH samples were significantly different. In total, 27 and 30 metabolites from GC-TOF-MS and UPLC-QTOF-MS analysis, respectively, were annotated as highly discriminative metabolites. Among the differential compounds, the relative contents of most amino acids showed the highest in the LWH sample ripened for two years, while some metabolites with potential therapeutic effects such as levetiracetam were the most abundant in the LWH sample ripened for three years. The correlation analysis indicated that the dominant microbes were closely related to differential metabolites, highlighting the importance of their functional characterization. Findings indicate that the consumption of LWH contributes to microbiological and chemical diversity of human diets as well as suggests efficacy of combining GC-MS and LC-MS to study the metabolites in dry-cured meat products.Item Contribution of wild foods to diet, food security, and cultural values amidst climate change(2019-11) Smith, Erin; Ahmed, Selena; Running Crane, MaryAnn; Eggers, Margaret J.; Pierre, Mike; Flagg, Kenneth A.; Byker Shanks, CarmenWild foods are recognized to contribute to diet and food security through enhancing the availability of local, diverse, and nonmarket food sources. We investigated the contribution of wild foods to diet, food security, and cultural identity in a Native American[1] community in the context of climate change. Structured interviews were conducted with low-income residents of the Flathead Indian Reservation[2] in Northwestern Montana who participate in the federal Food Distribution Program on Indian Reservations, also known by participants as ‘Commodities.’ Responses to structured questions were analyzed for frequency, and open-ended responses were coded and analyzed to identify prevalent themes. Our analysis indicated that half of participants were food insecure. Approximately 28% of participants engaged in at least one wild food procurement activity, including hunting, fishing, and harvesting. On average, participants who engaged in one or more wild food procurement activities were more food secure than those who did not. Results highlight the multidimensional valuation of wild foods by participants including taste, freshness, nutritional quality, being a traditional community practice, and providing a sense of self-sufficiency. Climate change is perceived by participants to be adversely impacting wild food systems due to increased variability in seasonality and precipitation and increased incidences of wild fire. Findings point to the need for community-based strategies to strengthen wild food knowledge toward enhancing food sovereignty in Native American communities, in the context of climate change. [1] The term ‘Native American’ was determined to be the preferred term for referencing the Native American community in this study, based on consultation from our community advisory board. [2] The term ‘Flathead Indian Reservation’ was determined to be the preferred term for referencing the location in which this study was held, based on consultation from our community advisory board.Item Diversity, knowledge, and valuation of plants used as fermentation starters for traditional glutinous rice wine by Dong communities in Southeast Guizhou, China(2019-04) He, Jianwu; Ruifei, Zhang; Lei, Qiyi; Chen, Gongxi; Li, Kegang; Ahmed, SelenaBACKGROUND Beverages prepared by fermenting plants have a long history of use for medicinal, social, and ritualistic purposes around the world. Socio-linguistic groups throughout China have traditionally used plants as fermentation starters (or koji) for brewing traditional rice wine. The objective of this study was to evaluate traditional knowledge, diversity, and values regarding plants used as starters for brewing glutinous rice wine in the Dong communities in the Guizhou Province of China, an area of rich biological and cultural diversity. METHODS Semi-structured interviews were administered for collecting ethnobotanical data on plants used as starters for brewing glutinous rice wine in Dong communities. Field work was carried out in three communities in Guizhou Province from September 2017 to July 2018. A total of 217 informants were interviewed from the villages. RESULTS A total of 60 plant species were identified to be used as starters for brewing glutinous rice wine, belonging to 58 genera in 36 families. Asteraceae and Rosaceae are the most represented botanical families for use as a fermentation starter for rice wine with 6 species respectively, followed by Lamiaceae (4 species); Asparagaceae, Menispermaceae, and Polygonaceae (3 species respectively); and Lardizabalaceae, Leguminosae, Moraceae, Poaceae, and Rubiaceae (2 species, respectively). The other botanical families were represented by one species each. The species used for fermentation starters consist of herbs (60.0%), shrubs (23.3%), climbers (10.0%), and trees (6.7%). The parts used include the root (21.7%), leaf (20.0%), and the whole plant (16.7%). Findings indicate a significant relationship between knowledge of plants used as fermentation starters with age (P value < 0.001) and educational status (P value = 0.004) but not with gender (P value = 0.179) and occupation (P value = 0.059). The species that are most used by informants include Pueraria lobata var. montana (Lour.) van der Maesen (UV = 1.74; Leguminosae), Actinidia eriantha Benth. (UV = 1.51; Actinidiaceae), Oryza sativa L. var. glutinosa Matsum (UV = 1.5; Poaceae). CONCLUSION This study highlights that while most of the Dong informants continue to use a diverse range of plants as a fermentation starter for brewing glutinous rice wine, knowledge of these plants is being lost by the younger generations. Documentation of traditional ethnobotanical knowledge and outreach is thus needed to conserve biocultural diversity in the rural Dong communities in southern China.Item The Role of Montane Forests for Indigenous Dongba Papermaking in the Naxi Highlands of Northwest Yunnan, China. Mountain Research and Development.(2011-11) Yang, Lixin; Stepp, John R.; Ahmed, Selena; Pei, Shengji; Xue, DayuanChina's rapid economic development is influencing cultural practices and natural resource management in indigenous mountain communities throughout the country. Numerous studies have documented loss and change of cultural practices and environmental degradation in indigenous communities with the expansion of roads, markets, tourism, and other infrastructure development. The present study focuses on papermaking, a socioecological practice that began in China, as a case study to examine the influence of development on cultural practices and natural resource management. The Naxi are an indigenous people who primarily inhabit the mountains of the eastern Himalaya in China's northwest Yunnan province. The Naxi people are unique in that they have the last remaining pictographic writing system in the world. The Naxi pictographic script is customarily learned and mastered by shaman priests known as Dongba (Dto'mba) who transmit their knowledge to their sons. Approximately 300,000 Naxi live in this area. The pictographic system is transmitted on paper sourced from montane forest resources, primarily Wisktroemia delavayi. This cultural tradition almost disappeared during the Cultural Revolution in China during the 1960s and 1970s but has recently seen a revival. Research involved both ethnographic interviews and ecological sampling. Semistructured interviews were conducted with 100 informants between 2002–2011 to understand the management and use of W. delavayi for Dongba papermaking and the impact of market integration on papermaking. Sample plots were surveyed for floristic composition and structure in the 3 vegetation types where W. delavayi grows. Density, height, diameter, and number of branches of W. delavayiplants were recorded within each plot. Ecological importance values were calculated based on relative density, relative dominance, and relative frequency to determine the habitat where W. delavayidemonstrates the greatest growth. Additional plots were surveyed to understand the regeneration of W. delavayi after the local harvest cycle.
