Wild edible plants contribute significantly to food security, environmental protection, cultural heritage preservation, economic diversification, and the development of communities. In this paper, we present an inaugural ethnobotanical investigation of the traditional knowledge on wild edible plant species from Makkah, Kingdom of Saudi Arabia. Ethnobotanical fieldwork was conducted in Makkah from January to February 2025. Ethnobotanical data pertaining to wild edible plants were collected from 102 informants through free listing, semi-structured interviews, field observations, and a survey of the market. The data were analyzed based on descriptive statistics, the relative frequency of citation, preference ranking, and priority ranking. Forty-one out of one hundred and eighty-four wild plants were gathered and recognized as wild edible plant species belonging to twenty-one families. Poaceae showed the greatest species diversity, comprising five plant species (12%). Phoenix dactylifera L. is the most common wild edible plant. Notably, 11 of the 41 wild edible plants identified in this study had never been reported in the Kingdom of Saudi Arabia before. Wild edible plants are currently threatened by several anthropogenic sources in the research region, including overgrazing, fuel wood collection, and the repeated use of multiple species. Therefore, to ensure sustainable future usage, wild food plants must be used carefully and should be the subject of targeted conservation efforts from all stakeholders. Full article

Zambia continues to experience increasingly frequent and intense droughts, with the 2023/2024 season among the most severe in recent history. These events have threatened livelihoods, strained water and food systems, and placed immense pressure on already limited national and local resources. Given the limited knowledge in the literature on drought management in Zambia, this study investigated the state of localized district efforts across the country. By using mixed methods with a total of 161 interviews, it assessed the participation of district governments and sector players across key components of drought governance, including early warning, monitoring, vulnerability and impact assessment, mitigation, and response. Although Zambia has made notable progress in establishing national institutional frameworks and climate policies, key findings reveal a pattern of limited proactive engagement, with most participation occurring only in response to extreme events like the 2023/2024 drought. This reactive posture at the district level is further compounded by inadequate resources, limited coordination, a lack of localized drought planning, and systemic bureaucratic constraints that undermine a timely and effective response. Nonetheless, numerous opportunities exist to strengthen drought management by localizing decision-making, integrating indigenous knowledge into existing early warning systems, and leveraging community-based infrastructures to maximize scarce resources and build long-term resilience. The paper concludes with recommendations for enhancing Zambia’s drought preparedness and response capacity through inclusive, risk-based, and proactive strategies; insights that can be adapted to other developing country contexts.

Cabbage (Brassica oleracea Linnaeus) is an important vegetable crop for food security and income generation for farmers in the Democratic Republic of Congo (DRC). However, production is severely undermined by a complex of insect pests. This study investigates farmers’ knowledge, perception, and pest management practices in key cabbage-growing areas surrounding Goma city in Eastern DRC. A total of 430 farmers were interviewed using a structured survey administered via the KoboToolbox platform. The diamondback moth (Plutella xylostella Linnaeus, 1758) and the cabbage aphid (Brevicoryne brassicae Linnaeus, 1758) were identified as the main pests, with peak incidences reported during the dry mid-season. Pest damages are most frequently observed at the post-transplanting and heading stages of cabbage. Although chemical control was the dominant strategy (69.4%), concerns arise due to the widespread use of moderately to highly hazardous insecticides, including pyrethroid, organophosphorus, and avermectin-based formulations. The insufficient use of personal protective equipment (PPE) and limited training on safe pesticide handling remain further challenges. While indigenous practices, such as crop rotation, handpicking of insects, and the use of botanical extracts, are employed to a lesser extent, awareness and implementation of biological control are almost nonexistent. The findings underscore the need to promote integrated pest management (IPM) approaches based on agroecological principles, including the safe use of (bio-)pesticides, training programs, and stakeholder engagement to enhance sustainable cabbage production.

Climate change remains one of the existential threats to humanity in particular and life on earth in general. It presents significant impacts on food and nutritional security, health, and the general well-being of living organisms globally. Despite global efforts to tackle the climate crisis, the record shows that limited progress has been made in curbing the problem. Consequently, this study intends to address the following research question: How does the climate crisis affect indigenous food systems, farmers’ livelihoods, and local communities in the study area? This study was conducted in the Tolon district of the northern region of Ghana from 2017 to 2022. Grounded in the theoretical prism of political ecology and indigenous knowledge perspective, we selected individuals who were smallholder farmers, students, faculty members, extension officers, and an administrator from the Ministry of Food and Agriculture. The data were gathered through in-depth interviews, focus groups, and workshops and analyzed using coding, thematization, and inferences drawn from the literature and authors’ experiences. This study discovered some of the effects of a changing climate, including the extinction of indigenous food crops, poor yield resulting in poverty, and food and nutritional insecurity. This study concludes that failure to tackle climate change could pose a greater threat to the survival of smallholder households in Ghana. Full article

The valorization of local plant cover, particularly through the integration of indigenous knowledge, is central to Tunisia’s economic development strategies. These approaches focus on diversifying agriculture by enhancing local natural and cultural heritage to strengthen community resilience amid environmental and socio-economic changes and to address rural exodus. This study examines the feasibility of AMP-based micro-projects in Matmata (southeastern Tunisia) by applying the Water–Energy–Food–Ecosystem (WEFE) nexus and participatory methods involving local stakeholders. Field surveys, literature reviews, and statistical analyses reveal growing youth interest in AMP ventures, driven by rising pharmaceutical and cosmetic demand. Economic viability is confirmed by internal rate of return (IRR) values of 32%, 28%, and 43%, all well above the 10% profitability threshold. Profitability index (PI) values indicate efficient investments, yielding returns of 2.64, 2.13, and 5.31 dinars per dinar invested. The initiatives also deliver socio-cultural and environmental benefits through WEFE-based resource management. Beyond profitability, the study identifies gaps and opportunities to enhance AMP biodiversity, resource management, and sustainable diversification in southern Tunisia. Further efforts are required to increase market value and ensure equitable benefit distribution. Government policies should focus on raising WEFE awareness, building capacity, and investing in climate-smart agriculture, especially in vulnerable, migration-prone regions, supported by reforms in financing, taxation, and spatial planning.

Traditional knowledge of edible plants is essential for food security, nutrition, and cultural identity in rural communities, yet many regions, including Mueang District, Yasothon Province (MY), remain underexplored in ethnobotanical studies. The lack of systematic documentation of local plant diversity and uses in MY presents a significant gap in understanding how these resources contribute to the sustainability of local food systems. This study addresses this gap by providing a comprehensive ethnobotanical survey of edible plants in Mueang District, Northeastern Thailand. Documenting 170 species across 60 families, the study reveals a rich plant diversity reflecting a dynamic interplay of native and introduced species, as well as cultivated and wild-harvested resources that sustain local food security, nutrition, and cultural traditions. Fabaceae emerged as the most species-rich family, while staple cereals such as Oryza sativa L. and Zea mays L. dominate use-value rankings. Quantitative indices, including Species Use Value (SUV), Relative Frequency of Citation (RFC), Cultural Food Significance Index (CFSI), and Fidelity Level (%FL), elucidate nuanced patterns of plant utilization, highlighting multifunctional species that bridge food and medicine. High cultural consensus on key medicinal plants underscores the deep integration of traditional healthcare within local food systems. The diversity of edible plant uses—from beverages and condiments to medicinal foods—illustrates adaptive strategies that enhance dietary diversity and ecological resilience. These findings contribute to the understanding of biocultural diversity and underscore the importance of conserving both plant biodiversity and indigenous knowledge to promote sustainable, locally adapted food systems. The study also identifies priority species for future pharmacological and agronomic research to support climate-resilient food sovereignty. Full article

In the forests of Jambi Province, Indonesia, the Indigenous Suku Anak Dalam have encountered rapid alterations to the environment upon which they previously depended. Their culinary traditions—and the knowledge that accompanies them—are placed at a greater risk as palm oil plantations expand and forest areas diminish. This research is based on extensive interviews with customary leaders (called Tumenggung, who guide communal life and cultural practices), elders, and women in five settlements in Merangin District. Rather than regarding participants as research subjects, we engaged with their narratives. The image that emerged was not merely one of food scarcity but also one of cultural loss. Instead of forest tubers, untamed fruits, or fish, families now depend on instant noodles or cassava. The rivers are no longer clean, and the trees that were once a source of both sustenance and medicine are largely extinct. Nevertheless, individuals devise strategies to adapt, including cultivating small crops in the vicinity of their dwellings, collecting what is left along the plantation’s perimeter, and distributing their meager possessions to their neighbors. This research demonstrates that food security for Indigenous peoples is not solely dependent on agriculture or nutrition. It is about the right to have a voice in one’s own land, dignity, and memory. Genuine solutions must transcend technical fixes and nutritional aid. The first step is to respect Indigenous voices, protect their territories, and support their methods of knowing and living before they are also lost. Full article

Pulque, an available traditional Mexican fermented beverage, has deep ethnographic and cultural significance. It was originally consumed by pre-Columbian civilizations, including the Teotihuacanos, Mexicas, Otomies, Zapotecas, Mixtecas, and Maya. It was revered as a sacred drink with both ceremonial and medicinal uses, often reserved for elites and priests. Its production is based on the ancestral extraction and fermentation of aguamiel, a sweet sap obtained from agave plants. While advances in food technology have occurred, traditional techniques for obtaining and fermenting aguamiel remain prevalent, especially in rural communities, reflecting the resilience of indigenous knowledge systems. Recent interest in pulque has focused on its nutritional content and potential health benefits when consumed in moderation, though risks related to excessive intake remain a concern. Moreover, cultural initiatives aim to revitalize indigenous heritage through gastronomic promotion, tourism routes, and festive traditions. This study explores pulque’s production processes, its cultural symbolism, and its evolving role within Mexican society, suggesting that its survival reflects both continuity and adaptation in the face of modernity. This paper is also presented as a narrative integrative review to explore the biocultural significance of pulque across the anthropological, historical, biochemical, and public-health domains.

Wild edible fruit plants are integral to the cultural, nutritional, medicinal, and economic practices of Indigenous Isan communities in Roi Et Province, northeastern Thailand, a region characterized by plateau and lowland topography and a tropical monsoon climate. This study aimed to document the diversity, traditional uses, phenology, and conservation status of these species to inform sustainable management and conservation efforts. Field surveys and ethnobotanical interviews with 200 informants (100 men, 100 women; random ages) were conducted across 20 local communities to identify species diversity and usage patterns, while phenological observations and conservation assessments were performed to understand reproductive cycles and species vulnerability between January and December 2023. A total of 68 species from 32 families were recorded, with peak flowering in March–April and fruiting in May–June. Analyses of Species Use Value (0.19–0.48) and Relative Frequency of Citation (0.15–0.44) identified key species with significant roles in food security and traditional medicine. Uvaria rufa had the highest SUV (0.48) and RFC (0.44). Informant consensus on medicinal applications was strong for ailments such as gastrointestinal and lymphatic disorders. Economically important species were also identified, with some contributing notable income through local trade. Conservation proposed one species as Critically Endangered and several others as Vulnerable. The results highlight the need for integrated conservation strategies, including community-based initiatives and recognition of Other Effective area-based Conservation Measures (OECMs), to ensure the preservation of biodiversity, traditional knowledge, and local livelihoods.

This study investigates farmers’ knowledge, perceptions, and adaptation strategies to climate change in Rwanda’s Eastern Province, integrating social and physical science approaches. Analyzing meteorological data (1981–2021) and surveys from 204 farmers across five districts, we assessed climate trends and adaptation behaviors using statistical methods (descriptive statistics, Chi-square, logistic regression, Regional Kendall test, dynamic linear state-space model). Results show that 85% of farmers acknowledge climate change, with 54% observing temperature increases and 37% noting rainfall declines. Climate data confirm significant rises in annual minimum (+0.76 °C/decade) and mean temperatures (+0.48 °C/decade), with the largest seasonal increase (+0.86 °C/decade) in June–August. Rainfall trends indicate a non-significant decrease in March–May and a slight increase in September–December. Farmers report crop failures, yield reductions, and food shortages as major climate impacts. Common adaptations include agroforestry, crop diversification, and fertilizer use, though financial limitations, information gaps, and input scarcity impede adoption. Despite limited formal education (53.9% primary, 22.3% no formal education), indigenous knowledge aids seasonal prediction. Farm location, group membership, and farming goal are key adaptation enablers. These findings emphasize the need for targeted policies and climate communication to enhance rural resilience by strengthening smallholder farmer support systems for effective climate adaptation.

Access to high-quality, culturally responsive nutrition advice during pregnancy is necessary for optimal health outcomes for mothers and babies. Evidence indicates that age, education and access to trained healthcare practitioners have a positive correlation with healthy food intake and positive outcomes. There are limited studies that discuss the importance of providing culturally responsive nutrition advice to pregnant Indigenous women. Therefore, this paper investigates the sources from which Indigenous women access nutrition information, assesses its adequacy in meeting needs, and identifies the effective ways to deliver this information. This study took place in Queensland (QLD), New South Wales (NSW), and Western Australia (WA), which were chosen to represent diverse cultural communities. A total of 103 participants were recruited, including Indigenous women and healthcare practitioners. Focus groups were audio-recorded, transcribed and analysed. Participants indicated that pregnant women are highly interested in improving their nutrition knowledge during pregnancy and actively seek information from their healthcare practitioners and dietitians. Findings suggested dissatisfaction with the information received, as it failed to address their needs. Results of this paper call for an urgent increased presence of community dietitians in antenatal clinics dedicated to Indigenous pregnant women as an additional way to provide families with the information they need for healthy pregnancies.

Indigenous top-priority fruit trees, like Vangueria infausta subsp. infausta. Burch (wild medlar), are essential for food security, climate resilience, and biodiversity. However, they remain underutilized due to limited documentation and integration into agricultural systems. This study presents the first ethnobotanical assessment of the wild medlar in Oyemeni, northeastern KwaZulu-Natal, South Africa. Surveys and interviews were conducted with 100 rural participants to explore its traditional uses, commercialization potential, and knowledge transmission. The findings reveal that the fruit is widely used in porridges, juices, and traditional beer, offering nutritional benefits such as vitamin C. Medicinally, it is valued for promoting oral health, wound healing, and spiritual protection. However, traditional knowledge is declining, particularly among the youth, due to generational shifts and modernization. The study highlights sustainable commercialization opportunities, such as value-added products and agroforestry integration, while emphasizing the need to preserve indigenous knowledge. These findings contribute to food security, biodiversity conservation, and cultural preservation in a changing socio-economic landscape. Future research should focus on biochemical evaluation of the plant’s medicinal properties and cross-regional comparisons. Full article

Background/Objectives: Traditional nutritional knowledge, shaped by centuries of cultural and ecological adaptation, offers holistic and sustainable dietary frameworks that remain highly relevant to modern health challenges. However, current digital nutrition platforms often fail to reflect this diversity, relying instead on standardized models with limited cultural sensitivity. This paper aims to explore how traditional nutritional wisdom can be integrated into digital health platforms to promote more inclusive and effective approaches to personalized nutrition. Methods: This perspective paper employs a cultural adaptation framework to analyze the integration of traditional food knowledge into digital contexts. Drawing from interdisciplinary research across nutrition science, anthropology, digital health and implementation science, we utilize the Knowledge-to-Action (KTA) Framework and the PEN-3 Cultural Model to structure our analysis. A systematic scoping review of literature published between 2010 and 2025 was conducted to identify integration challenges and opportunities. Additionally, we analyzed case studies of three traditional dietary systems (Argentina, Italy and Japan) and evaluated five leading digital nutrition platforms for their degree of cultural inclusivity, using qualitative comparative methods. Results: The analysis highlights significant challenges in adapting traditional knowledge to digital formats, including standardization barriers, contextual loss and technological limitations. However, successful integration initiatives demonstrate that through participatory design, flexible data architectures and culturally-informed algorithms, traditional food systems can be meaningfully represented. Our proposed four-phase integration framework—documentation, digital adaptation, implementation and evaluation—provides a structured approach for developers and researchers. Conclusions: Bridging traditional nutrition with digital platforms represents a vital opportunity to enhance personalization and preserve food heritage while improving health outcomes for diverse populations. This integration requires interdisciplinary collaboration, user-centered design processes and ethical approaches that respect cultural ownership and context. Full article

This scoping review examines the state of academic knowledge around gender and its role in Indigenous/traditional knowledge for food sustainability in Tonga, Samoa, Solomon Islands and Fiji. The different roles played by all genders—men, women and non-binary—in the Pacific Islands can contribute to climate adaptation and knowledge preservation for sustainable food production. The gender lens is especially relevant given the fact that women’s knowledge has, in recent years, been disregarded and marginalised as a consequence of colonial influences and increasing reliance on imported foods. We analysed 14 studies published in English between 2015 and 2024—six from refereed journal articles and eight from grey literature. Three themes emerged linking agriculture, gender and traditional knowledge, as follows: (1) there is a gendered division of labour and culturally defined roles between women and men, although the roles played by non-binary groups remain unclear; (2) intergenerational traditional knowledge transmission has declined; (3) climate change adaptation could be reinforced through passing on traditional knowledge. The findings demonstrate that gendered knowledge is distinct and complementary, and this knowledge should be integrated into Pacific agricultural production to achieve resilient and sustainable farming in the face of climate change.

Background: In many African areas, herbal products still represent a significant source of healthcare. However, a major gender bias is evident in the literature, as most of the work is carried out by male researchers, collecting data from male traditional practitioners, and thus often neglecting women’s specific health issues. This warrants a detailed review of the current knowledge about the major medicinal plants historically and still used for women’s health. Objective: This study aims to compile and critically analyze published data on the use of traditional herbal remedies by African women in addressing specific health conditions, in order to evaluate the potential of traditional medicine as a viable alternative or complementary approach to modern healthcare for women globally. Methods: Data were retrieved from databases by combining the following relevant keywords: “abortion, adverse, Africa, attendant, birth, botanical, delivery, developing, drug, ethnomedicine, ethnopharmacology, folk, gynecological, healing, infertility, herb, indigenous, lactation, medicine, native, obstetric, phytomedicine, plant, pregnancy, remedy, side, sub-Saharan, traditional, treatment, women”. Results: More than 125 studies, carried out across 12 African nations, revealed that up to 80% of African women resort to herbal medicines. An estimated 200 medicinally important plant species are reported to be utilized by women in different African countries, including Benin, Cameroon, Côte d’Ivoire, Egypt, Ethiopia, Ghana, Kenya, Mali, Nigeria, South Africa, Tanzania, and Zimbabwe. These herbs have many applications, mostly focused on infertility, pregnancy, painful menstruation, breast feeding, breast cancer, and contraception. Interestingly, according to their occurrence of usage, the plants most commonly reported for these conditions that are important to women are ambivalent plants (i.e., used both as foods and medicines) that include Zingiber officinale Roscoe, Allium sativum L., Cucurbita pepo L., and Ricinus communis L. Conclusions: Even though most women, in most African countries, do use traditional medicine, the amount of work published remains quite limited and no data are available in many countries. Therefore, it is desirable to expand African studies in this direction. Full article
