Rahayu YYS, Sujarwo W, Irsyam ASD, Dwiartama A, Rosleine D. Exploring unconventional food plants used by local communities in a rural area of West Java, Indonesia: ethnobotanical assessment, use trends, and potential for improved nutrition. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2024; 20:68. [PMID: 39030547 PMCID: PMC11264525 DOI: 10.1186/s13002-024-00710-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/26/2024] [Accepted: 07/12/2024] [Indexed: 07/21/2024]
Abstract
BACKGROUND As one of the world's biodiversity hotspots, Indonesia contains over 25,000 plant species, including unconventional food plants (UFPs). These plants are integral to the dietary practices of rural communities, providing essential nutrients often overlooked in modern diets. However, the use of UFP is declining, with both their dietary and cultural values being undermined. In rural West Java, this decline in UFP biodiversity coincides with public health challenges related to malnutrition. This study aims to document the diversity of UFPs used by local communities in rural West Java, assess their nutritional value, and explore their consumption practices. METHODS Data were collected using mixed methods, including interviews with 20 key informants and food frequency questionnaire administered to 107 women in three villages in the area. The nutritional compositions of documented UFPs were obtained from literature and analysis. Bivariate correlation was used to analyze the relationships between UFP consumption frequency and potential correlates. RESULTS The study documented 52 species of UFPs from 29 families, many of which are rich in nutritional value. About half of respondents (56%) consumed UFPs moderately (2-3 times a week). UFP consumption frequency had a strong correlation (r = 0.70) with associated knowledge (r = 0.70, p < 0.01) and a weak correlation with age (r = 0.240, p = 0.015), livestock possession (r = 0.260, p = 0.008), and family size (r = - 0.220, p = 0.02). Motivations for UFP consumption included availability as free food (33%), medicinal value (26%), nostalgic value (23%), and preferred taste (18%). Most respondents (92%) agreed that consumption has declined compared to the past, with perceived reduced availability and lack of knowledge cited as the primary reasons for the declining trend. CONCLUSIONS UFP use is common in the study area, where local communities value these plants for their critical roles in diet, medicine, and culture. Given their significant potential to meet dietary needs, educating and raising awareness about UFPs can enhance their consumption and contribute to food and nutrition security.

Rashidi S, Yousefi AR, Mastinu A. Mycorrhizal Symbiosis Can Change the Composition of Secondary Metabolites in Fruits of Solanum nigrum L. Chem Biodivers 2024; 21:e202400208. [PMID: 38713365 DOI: 10.1002/cbdv.202400208] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 05/03/2024] [Accepted: 05/06/2024] [Indexed: 05/08/2024]
Abstract
Solanum nigrum is a common weed in arable land, while being used in traditional medicine around the world due to its remarkable levels of valuable secondary metabolites. Agronomic and biological techniques can alter the production of a specific metabolite by influencing plant growth and metabolism. The effects of colonization with three arbuscular mycorrhizal fungi (AMF), including Funneliformis mosseae, Rhizoglomus intraradices, and Rhizoglomus fasciculatum, on the chemical composition of S. nigrum fruits were evaluated by gas chromatography-mass spectrometry (GC-MS) analysis. More than 100 different chemical constituents were evaluated by GC-MS. Our study revealed that the levels of phenols (quinic acid), benzenes (hydroquinone), sulfur-containing compounds, lactone and carboxylic acids were improved by R. intraradices. In contrast, hydroxymethylfurfural increased by 68 % in R. fasciculatum inoculated with uninoculated S. nigrum plants, and this species was also the most efficient in inducing sugar compounds (D-galactose, lactose, and melezitose). Our results suggest that AMF colonization is an effective biological strategy that can alter the chemical composition and improve the medicinal properties of S. nigrum.

Gomes LCA, Medeiros PMD, Prata APDN. Patterns of use of wild food plants by Brazilian local communities: systematic review and meta-analysis. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2023; 19:47. [PMID: 37880767 PMCID: PMC10601232 DOI: 10.1186/s13002-023-00619-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 10/20/2023] [Indexed: 10/27/2023]
Abstract
BACKGROUND This systematic review and meta-analysis sought to investigate the patterns of use of native wild food plants of Brazil (native and non-cultivated). METHODS We searched ethnobiological works with food plants in Web of Science, Scielo, Scopus and PubMed using different sets of keywords. Initially, the studies were evaluated based on inclusion criteria (systematic data collection instruments, such as interviews; specification of methods for data collection; and the presence of a species list). The methodological quality of each study was evaluated to define the risk of bias. A total of 20 articles met all criteria and were included in the review. RESULTS The results showed that there was a predominance of consumption of fruits, followed by leaves and seeds, which together represented 85.8% of the total parts. As for the meta-analysis, there was a predominance of use of plant parts classified as reproductive, non-persistent, non-destructive and parts of woody plants. There was no interference from the type of ecosystem (seasonally dry x moist). The results did not support the seasonality hypothesis. CONCLUSIONS The concentration of studies in the Northeast, Southeast and South regions of Brazil and in the Atlantic Forest and Caatinga biomes points to the need for a greater effort in terms of quantitative ethnobotanical research in other regions and biomes. The predominance of fruits and plant parts classified as reproductive, non-persistent and non-destructive points to the high potential for implementation of sustainable management strategies aimed at these plants in the country.

Very High Food Plant Diversity among Ethnic Groups in Northern Thailand. DIVERSITY 2023. [DOI: 10.3390/d15010120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 01/17/2023]
Abstract
The combination of the high biodiversity and many ethnicities in Thailand results in extensive ethnobotanical studies, especially in the northern part of the country. Here we have assembled 7620 records from 60 references regarding how plants are used for food among 14 ethnicities in northern Thailand. The uses are based on 1182 different plant species. Vegetables are the most common food category, which contributed more than 60% of all use-reports and involved nearly 900 species. This was followed by the dessert fruit category, which included about 350 species and over 1800 use-reports. The similarity among the different ethnicities was low and the number of uses and species recorded among different ethnicities were significantly related to the number of studies that had been conducted for each group. This implies that additional ethnobotanical studies are still needed in order to conserve and compile the valuable traditional knowledge related to food plants. Many exotic species are now an important part of traditional knowledge, whereas rare endemic species are uncommon among wild food plants. This situation leads to a loss of traditional knowledge about food plants and reduced awareness of their importance. As a key to using this great reservoir of food for local people, traditional knowledge related to local wild food plants can contribute to the zero-hunger goal of the Sustainable Development Goal (SDG). More studies on the nutrient content and health properties of these plants could lead to the development of new crops to meet present consumer demands.

Yangdon P, Araki T, Rahayu YYS, Norbu K. Ethnobotanical study of wild edible fruits in eastern Bhutan. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2022; 18:27. [PMID: 35354474 PMCID: PMC8966357 DOI: 10.1186/s13002-022-00526-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Accepted: 03/22/2022] [Indexed: 05/08/2023]
Abstract
BACKGROUND In the past, wild edible fruits (WEFs) were a significant source of food and nutrition in Bhutan. These nutrient-rich species can enhance food security and alleviate poverty in Bhutan. However, recent developments like the introduction of improved fruit varieties, changes in dietary choices, and infrastructure development are expected to influence indigenous knowledge and consumption of WEFs. We aimed to document the species diversity of WEFs and their uses in eastern Bhutan and examine how the knowledge and consumption of WEFs vary with socio-demographic factors. METHODS A total of 97 households in two districts were selected to participate in the survey. A semi-structured questionnaire was used to interview a selected adult from each household. Comparative analysis of indigenous knowledge and consumption of WEFs among the socio-demographic factors was performed using one-way ANOVA and a Chi-square test on R software. RESULTS The present study reported 52 species of WEFs belonging to 35 families. The prevalence of WEF consumption was found to be 42%. WEF consumption differed significantly between districts, age groups, and indigenous knowledge levels. Similarly, indigenous knowledge of WEFs was significantly associated with districts and age groups. CONCLUSIONS Eastern Bhutan has a rich diversity of WEFs, but their consumption has been decreasing. Recent agricultural and infrastructure developments may have impacted the consumption and indigenous knowledge of WEFs in this region. Thus, domestication and agro-processing of WEFs should become a major focus in Bhutan to utilize their nutritional value and potential economic benefits to enhance food security in the country. Additionally, incorporating WEF-related knowledge in the school curriculum is essential to educate younger generations on WEFs.

Abstract
Locally harvested wild edible plants (WEPs) provide food as well as cash income for indigenous peoples and local communities, and they are of great importance in ensuring local food security. However, their uses and availability are poorly documented. This study aimed to enumerate WEP diversity and status of WEPs in a part of the Annapurna Conservation Area, Sikles region, where the population is dominated by the Gurung community. Ethnobotanical data were collected using guided field walks, semi-structured interviews, and field observation. The informant consensus method was employed and group discussions were conducted for triangulation of the information. Free listing and identification tests were performed to assess the knowledge of the informants. Both descriptive statistics and quantitative ethnobotanical methods were used for data analysis. A total of 72 wild food species belonging to 46 families and 61 genera were reported from the study area. Asparagaceae and Rosaceae were the dominant families, and herbs were the dominant life form. Fruits (34 species) were the most frequently used plant parts, followed by young shoots (16 species). Most edible plants were consumed in summer and during rainy seasons. While the age and type of informants had an influence on the number of enumerated plants, gender did not. Key informants and people aged 30-45 reported more species than other groups of respondents. Most of the knowledge about the use of WEPs was acquired from parents and relatives. The consumption of these plants was attributed to diversifying cuisine, spicing staple food, nutri-medicinal values, and cultural practices. People perceived the availability of WEPs to be gradually decreasing. However, WEPs are still abundant and diverse in the study area, and knowledge on their use is well-preserved. These resources provide food and nutrients to local people and can also be a source of cash income. Therefore, the documented information on WEPs may serve as baseline data for further studies on nutritional values and provide guidelines for safe collection. The results also revealed that many wild species are under growing pressure from various anthropogenic factors, suggesting effective community engagement is required for their conservation.

Abstract
Simple Summary Indigenous communities are a large resource of increasingly endangered, traditionally used medicinal plants and the associated ecological knowledge, which needs to be documented quickly as the base to establish sustainable livelihoods and healthcare systems. Through the interaction of indigenous knowledge, biodiversity, and the surrounding environment, these communities have developed their livelihoods over time. In this study, we tried to obtain an in-depth understanding of ethnomedicinal, cultural, and ritual perspectives on plant diversity in the Ladakh region and evaluated how the wild flora of Ladakh could improve local livelihoods and alleviate poverty. By surveying and applying open- and close-ended semi-structured interviews and group discussions in three communities, we documented 105 ethnobotanically important plants belonging to 39 families. The Balti and Brokpa ethnic groups showed greater similarity, whereas the least overlap in plant use was observed between Beda and Brokpa. Plants common to all cultures were mostly used for medicinal applications, while some were also used for religious purposes in the two major religions (Islam and Buddhism). A total of 37 species were shared by all cultures (Balti, Brokpa, and Beda). The cluster analysis elucidated three major clusters of different ethnobotanical usage. The first cluster included food and medicinal plants, the second included clusters of dye and flavor plants, and the third included plants used for fragrance, oil, fuel wood, and fodder. Plant parts were collected based on their availability in distinct pheno-phases according to the Tibetan traditional calendar. This study’s findings revealed that plants provide tangible economic benefits to indigenous communities, in addition to aiding in the treatment of various ailments. Sustainable use and management of wild resources can help improve livelihoods and food security and alleviate poverty. Abstract The nomadic pastoral indigenous communities of the Ladakhi people share roots with Tibetan culture in terms of food, clothing, religion, festivals, and habits, and rely widely on plant resources for survival and livelihood. This survey was conducted during 2019–2021 to document the indigenous knowledge about plant resources of the Balti, Beda, and Brokpa communities of the Ladakh region, trans-Himalayas. Open- and close-ended semi-structured interviews (N = 184) and group discussions (N = 17) were used to collect the data. Quantitative data was further analyzed using various statistical tools. A total of 105 plant species belonging to 82 genera and 39 families were used as medicine, fuel wood, fragrance, oil, food, flavor, fodder, decoration, and dye. Among these, medicinal use was most prevalent, with 70% of use reports, followed by fodder and fuel wood. Leaves (27%) were the most preferred plant part used, followed by roots and flowers. The principal component analysis revealed five clusters of ethnobotanical usage, i.e., food, medicine, fuel wood, fodder, and fragrance, oil, dye, and flavor. The maximum number of plant species used was reported by the Brokpa, while the Beda reported the minimum number of plant species uses. Delphinium brunonianum, Waldheimia tomentosa, and Juniperus indica played a significant role in the cultural and religious ritual aspects, whereas Allium przewalskianum, Waldheimia tomentosa, Juniperus indica, and Hippophae rhamnoides were commonly used as a livelihood source among Ladakhi communities. The local people collected most plants (65%) for self-consumption, while the rest (35%) were sold in markets as a source of income. The sustainable utilization and management of plant resources by local people is a strategy to boost livelihoods and food security and alleviate poverty.

Abstract
Despite significant evidence base on quantifying ecosystem services, the role of biodiversity in supporting such services in diversified landscapes, and how indigenous communities exploit, utilize and manage plant resources in a biocultural regime, remains understudied. This study examines the role of wild edible plants (WEPs) in meeting the food, nutrition and household income of indigenous communities under the biodiversity rich landscape of the Achanakmaar-Amarkantak Biosphere Reserve (AABR—22°15′ to 22°58′ N latitudes and 81°25′ to 82°5′ East longitudes) of Central India. Results revealed remarkable differences among Baiga, Gond, Kol, and Oraon ethnic communities and also location (core, buffer and transition) effect on utilization pattern of wild edibles. A sum total of 172 WEPs comprising 60 vegetables, 70 fruits, seeds and nuts, 23 underground tubers and 19 mushrooms were collected, consumed, and surplus were marketed by the communities. On average, the number of wild edibles collected annually by households were in the following quantities: 40–240 kg leafy vegetables, 125–386 kg flowers, 120–250 kg fruits, 12–125 kg legumes, 24–120 kg tubers, 5–35 kg mushrooms. Among ethnic groups, the Baiga primitive community utilized 70–90% followed by Gonds (58–81%), Kols (52–78%), Oraons (43–79%), and other communities (38–68%) in different zones. WEPs have contributed to 5–24% (Rs 3559- 12,710) of household income, which was highest in the core zone and lowest in the transition zone. It was observed that WEPs were complemented the diets rather than being a substitute for staple foods. They supplied only 3.7–8.3% of energy and 1.1–4.9% protein requirements; however, they significantly supplemented ascorbic acid, thiamine, calcium, and iron by 38.1–73%, 13.7–35.4%, 17.2–29.1%, 2.6–13.5%, respectively. Significantly higher quantities of nutrients were supplemented in the core zone compared to other zones. WEPs were currently underutilized (less intake) especially in buffer and transition zones, complementing the staple foods and partially supplementing the essential macro- and micro-nutrients. However, these have the potential to fulfill the dietary needs and ensure balanced nutrition, if consumed in recommended portions and sizes. The paper discusses policy implications that ensure coherence and coordination of local indigenous communities for conservation and sustainable utilization of WEPs of AABR, Central India.

Role of Traditional Ethnobotanical Knowledge and Indigenous Communities in Achieving Sustainable Development Goals. SUSTAINABILITY 2021.

Abstract
The sustainable development goals (SDGs) are a set of 17 goals with 169 targets. The Agenda 2030 of the United Nations envisages a holistic approach to achieve these goals by focusing on humankind and the planet. In this review, we analyzed the scientific literature and technical reports of international bodies such as the United Nations and Food and Agriculture Organization relating to traditional ethnobotanical knowledge (TEK). The literature on TEK was mapped with the targets of the SDGs to determine the role of traditional knowledge in the realization of selected goals and targets. Our extensive and systematic reviewing of available literatures suggests that, of the 17 goals, at least seven goals are associated with TEK. To achieve these seven goals, a thorough understanding is required to disentangle the intricacies involving TEK, indigenous people holding TEK, and their future role in achieving the SDGs. Our review points towards the role of TEK in achieving goals linked to poverty, health and wellbeing, responsible consumption and production, climate action, life on land, and partnerships. In summary, we argue that achieving the intended outcomes of the SDGs and the targets requires concerted efforts of all relevant stakeholders, including indigenous communities, common citizens, scientists, policy makers, and world leaders.

Abstract
Wild food plants (WFPs) are often highly nutritious but under-consumed at the same time. This study aimed to document the diversity of WFPs, and assess perceptions, attitudes, and drivers of change in their consumption among Minangkabau and Mandailing women farmers in West Sumatra. We applied a mixed-method approach consisting of interviews with 200 women and focus group discussions with 68 participants. The study documented 106 WFPs (85 species), and Minangkabau were found to steward richer traditional knowledge than Mandailing. Although both communities perceived WFPs positively, consumption has declined over the last generation. The main reasons perceived by respondents were due to the decreased availability of WFPs and changes in lifestyle. The contemporary barriers to consuming WFPs were low availability, time constraints, and a limited knowledge of their nutritional value. The key motivations for their use were that they are free and "unpolluted" natural foods. The main drivers of change were socio-economic factors and changes in agriculture and markets. However, the persistence of a strong culture appears to slow dietary changes. The communities, government and NGOs should work together to optimize the use of this food biodiversity in a sustainable way. This integrated approach could improve nutrition while conserving biological and cultural diversity.

Abstract
Wild edible plants are still eaten by a large section of the global population and ensure both affordable food and nutritional security. We tested this in an Indian context, where an enormous diversity of such plants constitutes a significant part of the rural diet and their acceptance has been high. In this study, we assessed the diversity of wild edible plant resource and the importance of species based on the use and its pattern. We have also shortlisted a set of plants to make an informed decision on prioritization. We found a great variety of plants (1,403 species) from 184 families were consumed across India, although the first 44 families (24%) contributed largely to the (75%) diversity. Leguminosae followed by Compositae, Poaceae, Malvaceae, and Rosaceae, were the families with the highest number of species. We note that a few species from the large pool were extensively used throughout the country while another few were valued for their multiple edible plant parts. Leafy shoots (722 species) followed by fruits (652 species) were the two most-eaten plant parts. Our results strengthen the fact that: (a) wild edibles have been an integral part of the diet; (b) their widespread assimilation into local food culture suggests an untapped potential to ensure easy availability and access to micronutrients for sustainable food systems, and thus in social welfare; and (c) they should be incorporated into the national food policy for formal cultivation and promotion.
