The Congo Basin peatlands, the world’s largest tropical peatland complex, are critical for global carbon storage yet remain poorly understood from a human dimension’s perspective. This study explores the perceptions, lifestyles, and knowledge systems of Indigenous Peoples and local communities around Lake Tumba, Democratic Republic of Congo, to identify practices supporting peatland conservation. Using a mixed-methods approach—household surveys (n = 320), focus groups, and statistical analyses including chi-square tests and Multiple Correspondence Analysis (MCA)—the study reveals a predominantly Indigenous agrarian society with limited formal education and strong reliance on peatlands for food (93.7%), construction materials (79.0%), and medicines (75.9%). While regulating services such as carbon storage were seldom recognized, traditional ecological knowledge was evident in sacred species protection, ritual plant and animal uses, and intergenerational knowledge transfer, mainly father-to-son. However, 95.3% of respondents cited religion as the main barrier to this transmission. MCA confirmed that livelihoods, village status, and ritual practices form an integrated socio-cultural system aligned with conservation. These findings stress the role of endogenous governance in sustaining peatland-compatible lifestyles. Conservation efforts should move beyond carbon-centered or top-down approaches to reinforce land tenure, traditional governance, and knowledge transmission, thereby protecting both peatlands and the cultural identities sustaining them.

The Fabaceae family plays a vital role in tropical ecosystems and human livelihoods due to its ecological, nutritional, and medicinal significance. This study provides a comprehensive ethnobotanical assessment of Fabaceae in Maha Sarakham Province, Northeastern Thailand. A total of 83 taxa representing 52 genera were recorded, reflecting the family’s high species richness and cultural importance in local communities. Field surveys and semi-structured interviews were conducted across diverse habitats, including homegardens, community forests, markets, and agricultural areas. Quantitative ethnobotanical indices—Species Use Value (SUV), Relative Frequency of Citation (RFC), Fidelity Level (FL), and Informant Consensus Factor (F_ic)—were used to evaluate species importance and cultural consensus. The highest SUV and RFC values were observed for Arachis hypogaea L., Glycine max (L.) Merr., Sesbania grandiflora (L.) Poir., and Vigna unguiculata subsp. sesquipedalis (L.) Verdc., indicating their central roles in local diets and livelihoods. Medicinally significant taxa, including Abrus precatorius and Albizia lebbeck, exhibited high FL and Fic values, reflecting strong community agreement on their therapeutic uses. Diverse applications—spanning food, medicine, fodder, fuelwood, dye, ornamental, and construction materials—highlight the multifunctionality of Fabaceae in rural livelihoods. The documentation of 44 new provincial records further emphasizes the value of integrating Indigenous and local knowledge into biodiversity assessments. These findings provide essential insights for sustainable utilization, conservation planning, and the integration of traditional knowledge with modern scientific approaches. Full article

Building resilient and sustainable food production systems is a major challenge in Sub-Saharan Africa (SSA) due to environmental, climatic, and economic pressures. Farmers in the region must adopt effective adaptation strategies to maintain productivity and contribute toward achieving the United Nations’ Sustainable Development Goal 2, “Zero Hunger.” Among these, water scarcity adaptation strategies are critical for building resilient food systems that also address poverty reduction. However, various obstacles hinder their widespread adoption, and documentation on these strategies remains fragmented. This paper examines available water scarcity adaptation strategies, the opportunities and challenges faced by farmers, and the policy and infrastructure implications for sustainable food production. The findings highlight the essential role of Indigenous Knowledge Systems (IKS) in adopting these strategies. IKS supports natural resource conservation, promotes inclusive market participation, strengthens institutional frameworks, and improves resource-use efficiency under climate stress. The paper recommends further research on transferring Indigenous Knowledge to future generations and exploring the role of policy in preserving and promoting IKS, especially within the SSA context. Emphasizing Indigenous Knowledge is crucial for creating sustainable, resilient agricultural systems that can thrive amid the region’s growing environmental challenges. Full article

The United Nations Sustainable Development Goal (SDG) 12.3 and the Malabo Declaration both address the critical issue of food loss and waste (FLW), but they differ in scope, timelines and regional focus. While SDG 12.3 provides a global framework and target of 2030, the Malabo Declaration reflects Africa’s pressing need to reduce FLW by 2025. Despite these targets and focus on FLW reduction by the global community, high FLW of fruits and vegetables continues to persist in many parts of Africa due to systemic constraints related to limitations in governance, financing and knowledge. It is estimated that up to 50% of nutritious fruits and vegetables are lost and yet supply hardly meets demand. The objective of this review was to identify the causes of FLW as well as possible solutions to reduce FLW in three fruit and vegetable values chains in East Africa. These three fruit and vegetable value chains were categorized as (i) “exotic, produced all year round, highly perishable and very inexpensive”, (ii) “exotic and indigenous, seasonal production, somewhat perishable and somewhat expensive” and (iii) “indigenous, produced all year round, extremely perishable and inexpensive”, represented by tomatoes, mangoes and indigenous leafy green vegetables, respectively. The upstream (farmer to market place) and downstream (market place to fork) causes of FLW are discussed and their respective solutions are suggested. The solutions provided herein are not only economically viable but also practical and can be adopted for the reduction of FLW in fruit and vegetable value chains in East Africa. This approach could result in the simultaneous increase of the access and affordability of fruits and vegetables for low-income consumers in East Africa. Full article

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.
