Wild food plants and trends in their use: from knowledge and perceptions to drivers of change in West Sumatra, Indonesia
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 âunpollutedâ 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
Medical ethnobotany of herbal practitioners in the Turkestan Range, southwestern Kyrgyzstan
This study recorded and analyzed traditional knowledge of medicinal plants in the Turkestan Range in southwestern Kyrgyzstan, where ethnobotanical knowledge has been largely under-documented to date. Data was collected through participant observation and both semi-structured and in-depth interviews with 10 herbal specialists. A total of 50 medicinal plant taxa were documented, distributed among 46 genera and 27 botanical families. In folk medicine they are applied in 75 different formulations, which cure 63 human and three animal ailments. Quantitative ethnobotanical indices were calculated to analyze traditional knowledge of the informants and to determine the cultural importance of particular medicinal plants. Ziziphora pamiroalaica, Peganum harmala, and Inula orientalis obtained the highest use value (UV). The best-represented and culturally important families were Lamiaceae, Asteraceae, and Apiaceae. Gastro-intestinal system disorders was the most prevalent ailment category. Most medicinal plants were gathered from nearby environments, however, species with a higher cultural value occurred at distant rather than nearby collection sites. The findings of this study proved the gap in documentation of traditional knowledge in Kyrgyzstan, indicating that further studies on the traditional use of wild plant resources could bring important insights into ecosystemsâ diversity with implications to human ecology and bio-cultural diversity conservation in Central Asia
An ethnobotanical study of medicinal plants used in Zacatecas state, Mexico
Despite the fact that Mexico has vast biocultural biodiversity, there are numerous regions where the traditional medicinal use of plants has not yet been studied. We aimed to document, analyze quantitatively, and preserve medicinal plant knowledge among local people living in over 40 communities in the state of Zacatecas. Ethnobotanical information was collected by semistructured interviews with 132 informants. Data were analyzed using standard quantitative indices such as relative frequency of citation, family importance value, cultural importance index, and informant consensus factor. We recorded 168 medicinal plant taxa belonging to 151 genera and 69 botanical families and used to treat 99 health disorders. The most medicinally important plant families were Asteraceae (20 species), followed by Fabaceae and Lamiaceae (12 species) and Cactaceae (five species). The most culturally important species was Matricaria chamomilla L., mentioned 140 times, followed by Arnica montana L. (62 times) and Artemisia ludoviciana Nutt (48 times). The highest consensus for use was for diseases of the reproductive system. The type of disorder for which there was the highest number of references for use (389; 25% of all uses) and plant species (67) were diseases of the digestive and gastrointestinal system. The present study represents the first quantitative medical-ethnobotanical documentation and analysis of the traditional use of medicinal plants in Zacatecas state. Despite the semiarid climate, this region is botanically highly diverse, and its flora have versatile medicinal uses
Born to eat wild: an integrated conservation approach to secure wild food plants for food security and nutrition
Overlooked in national reports and in conservation programs, wild food plants (WFPs)
have been a vital component of food and nutrition security for centuries. Recently, several countries have reported on the widespread and regular consumption of WFPs, particularly by rural and indigenous communities but also in urban contexts. They are reported as critical for livelihood resilience and for providing essential micronutrients to people enduring food shortages or other emergency situations. However, threats derived from changes in land use and climate, overexploitation and urbanization are reducing the availability of these biological resources in the wild and contributing to the loss of traditional knowledge associated with their use. Meanwhile, few policy measures are in place explicitly targeting their conservation and sustainable use. This can be partially attributed to a lack of scientific evidence and awareness among policymakers and relevant stakeholders of the untapped potential of WFPs, accompanied by market and nonâmarket barriers limiting their use. This paper reviews recent efforts being undertaken in several countries to build evidence of the importance of WFPs, while providing examples of crossâsectoral cooperation and multiâstakeholder approaches that are contributing to advance their conservation and sustainable use. An integrated conservation approach is proposed contributing to secure their availability for future generations
Beetles, ants, wasps, or flies? An ethnobiological study of edible insects among the AwajĂșn Amerindians in Amazonas, Peru
Abstract Background Insects are known to be able to provide valuable nutrients to indigenous populations across the Amazon. However, studies on traditional insect use in the Peruvian Amazon are scarce. This study documents edible insect diversity and characterizes their food and collection patterns in eight AwajĂșn communities in the Peruvian Amazon. Additionally, we reviewed what has been known to date about the nutrient composition of the documented species. Methods The survey was conducted among the AwajĂșn populations living in the Huampami, Paisa, Achu, and Tseasim communities in the Cenepa district and the Shijap, San Mateo, Kusu, and Listra communities in the Imaza district. Data collection was conducted through a freelisting exercise complemented by a semi-structured inquiry form in the AwajĂșn language. In total, 104 informants (72 men and 32 women) aged between 16 to 73Â years were interviewed. Results The AwajĂșn people use at least 12 insect species, with Rhynchophorus palmarum, Atta cephalotes, and Rhinostomus barbirostris being the most important ones. Beetles of the family Curculionidae represent the culturally most salient taxon. In the more accessible and developed Imaza district, the AwajĂșn tend to eat almost exclusively R. palmarum, while in the more isolated and preserved Cenepa district, the communityâs preferences are linked with more species. Although men are the main insect collectors, women cited more edible insects on average. The insects are eaten mainly roasted or raw. Further use patterns and differences between the districts are discussed. Conclusion Traditional knowledge related to edible insects and the ecosystems they occur in is widespread among the AwajĂșn populations, and insects still represent an important part of the indigenous food system. This ethnobiological survey discovered five species that are newly recorded as edible insects. Chemical composition of insects deemed edible by the AwajĂșn ought to be analyzed in the future and awareness about their nutritional importance should be raised to harness the potential of this underutilized yet nutrient-rich traditional food
Lessons learned from the Second International Agrobiodiversity Congress: Adopting agricultural biodiversity as a catalyst for transformative global food systems
Building more sustainable, equitable, and resilient food systems means rethinking how we consume, produce, and safeguard agrobiodiversity that can benefit the planet and secure access to nutritious food for all. This was the purpose of the 2021 Second International Agrobiodiversity Congress, convening scientists, Indigenous Peoples, entrepreneurs, and policymakers to share and advance research, nature-positive solutions, and policies. Congress organizers set out to showcase agrobiodiversityâs role in positively transforming food systems, present solutions and business opportunities to enhance multi-stakeholder collaborations, and reinforce the commitments made during international events of 2021. The take-home messages from this Congress support the 2021 UN Food Systems Summit to chart a path of concrete actions that can deliver on the 2030 Agenda for Sustainable Developmen
