Ethnobotanical review of wild edible plants used in the Czech Republic

This paper is the literature survey of wild food plants used within the present borders of the Czech Republic. Thirty-seven freely available publications documenting the culinary use of wild plants were examined. The use of 175 vascular plant species (approximately 5% of native and naturalized flora of the Czech Republic), 3 lichens and 1 bryophyte has been reported. For each species listed, plant parts used, use category and mode of consumption are given. Rosaceae, Asteraceae and Ericaceae were the most represented botanical families. The most frequently reported categories of plant uses include green vegetables (e.g. Urtica dioica, Glechoma hederacea, Rumex spp., Taraxacum sect. Ruderalia), seasonings (e.g. Juniperus communis, Viola spp.), wild fruits (e.g. Rubus idaeus, Rosa canina), and beverages (e.g. Cornus mas, Sambucus nigra). The structure of the most commonly used wild food taxa is similar to those used in other central European countries like Poland, Slovakia or Hungary. This review highlights the traditional knowledge of wild edible plants which were used in the Czech Republic since 16th century onwards with an attempt to document diversity of plant species and discuss the current potential of the forgotten plants used in the past

Investigation of Imperata sp. as a Primary Feedstock for Compost Production in Ucayali region, Peru

Five compost piles with different initial C : N ratios have been investigated in this study. As a primary feedstock Imperata sp. was used. The primary feedstock was mixed with poultry litter and vegetable refuse in order to obtain different C : N ratio. The results show that during 64 days of well managed composting under tropical conditions the initial C : N ratio between 30:1 and 50:1 decreased to ratio 11:1 to 15:1, respectively. Results of bioassay tests expressed as the germination index (GI) indicate particular compost phytotoxicity. The value of GI was 51.4%, 48.6%, 47.8%, 46.7% and 40.0% for samples from the compost with initial C : N ratios of 30:1, 37:1, 40:1, 44:1 and 50:1, respectively

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 “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

From Şxex to Chorta: The Adaptation of Maronite Foraging Customs to the Greek Ones in Kormakitis, Northern Cyprus

The traditional foraging of wild vegetables (WVs) has played an important role in the post-Neolithic development of rural local food systems of the Near East and the Mediterranean. This study assessed the WVs gathered by the ancient Maronite Arabic diaspora of Kurmajit/Kormakitis village in Northern Cyprus and compared them with those gathered by their Cypriot and Arab Levantine neighbors. An ethnobotanical field survey focusing on WVs was conducted via twenty-two semi-structured interviews among the few remaining Maronite elderly inhabitants (approximately 200); and the resulting data were compared with those described in a few field studies previously conducted in Cyprus, Lebanon, and coastal Syria. Wild vegetables in Kormakitis are grouped into a folk category expressed by the emic lexeme Şxex, which roughly corresponds to the Greek concept of Chorta (wild greens). The large majority of Şxex have Greek folk phytonyms and they overlap for the most part with the WVs previously reported to be gathered by Greek Cypriots, although a remarkable number of WVs are also shared with that of the other groups. The findings address a possible adaptation of Maronite WV foraging to the Greek one, which may be explained by the fact that the Maronite minority and the majority Greek communities lived side by side for many centuries. Additionally, after Turkish occupation in 1974, a remarkable migration/urbanization of Maronites to the main Greek centers on the southern side of the isle took place, and Kurmajit became part of Cypriot trans-border family networks

Methods for short-term control of Imperata grass in Peruvian Amazon

The traditional control of Imperata brasiliensis grasslands used by farmers in the Peruvian Amazon is to burn the grass. The objective of this study was to compare different methods of short-term control. Biological, mechanical, chemical and traditional methods of control were compared. Herbicide spraying and manual weeding have shown to be very effective in reducing above-and below-ground biomass growth in the first 45 days after slashing the grass, with effects persisting in the longer term, but both are expensive methods. Shading seems to be less effective in the short-term, whereas it influences the Imperata growth in the longer term. After one year shading, glyphosate application and weeding significantly reduced aboveground biomass by 94, 67 and 53%; and below ground biomass by 76, 65 and 58%, respectively, compared to control. We also found a significant decrease of Imperata rhizomes in soil during time under shading. Burning has proved to have no significant effect on Imperata growth. The use of shade trees in a kind of agroforestry system could be a suitable method for small farmers to control Imperata grasslands

Beetles, ants, wasps, or flies? An ethnobiological study of edible insects among the Awajún 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 Awajún 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 Awajún 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 Awajún language. In total, 104 informants (72 men and 32 women) aged between 16 to 73 years were interviewed. Results The Awajún 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 Awajún tend to eat almost exclusively R. palmarum, while in the more isolated and preserved Cenepa district, the community’s 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 Awajún 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 Awajún 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

A Proposed Typology of Farming Systems for Assessing Sustainable Livelihood Development Pathways in the Tien Shan Mountains of Kyrgyzstan

In Kyrgyzstan, most farming systems focus on animal husbandry, which depends on mixtures of crops and pastures around settlements and higher-elevation summer pastures. These farms face the problems of insufficient fodder production and pasture degradation due to overgrazing, resulting in low productivity of livestock and reduced household incomes. The spatial diversity of farms often hampers the development of interventions aimed at improving crop and animal productivity, as well as sustainable grassland management, while the absence of a comprehensive and systematic classification system that effectively encompasses the diverse range of livelihood strategies within farming systems presents a significant obstacle to the advancement of initiatives promoting sustainable livelihoods. This study aimed to develop a consistent typology of smallholder farms in the Tien Shan using multivariate analysis. By analyzing data from 235 farm-households and evaluating key classification variables, we identified two distinct farming systems, upper mountain farms and lower mountain farms, based on socioeconomic and agro-ecological characteristics. Our typology considers elevation, grazing period, cultivated area, and off-farm income and better captures the diversity of farming activities and household income compared to current classification models. These findings will inform and tailor policies and interventions suitable for enhancing sustainable livelihoods in Kyrgyzstan’s mountain farming systems

Classification of Mountain Silvopastoral Farming Systems in Walnut Forests of Kyrgyzstan: Determining Opportunities for Sustainable Livelihoods

Kyrgyz walnut-fruit forests are unique ecosystems inhabited by silvopastoral farm households that depend on forest resources for their livelihoods. Illegal logging, excessive collection of non-timber forest products (NTFPs), and overgrazing of forest pastures negatively affect forest regeneration and biodiversity, ultimately impacting sustainable livelihoods in the region. Understanding farm heterogeneity is critical to identify targeted interventions that have the potential to improve livelihood sustainability for local populations. This study identifies and elucidates the typology of farms in walnut-fruit forests. Data were collected from 220 farm-households in three villages located within or in the buffer zone of protected areas. Principal component analysis (PCA) and cluster analysis were used to analyze quantitative data and aggregate farms into clusters according to forest resource availability and use, production means, and socioeconomic characteristics. Three distinct silvopastoral farming systems were identified, in which farmers collect and sell NTFPs, but also have: (i) relatively high NTFP income, medium-sized livestock herds, and low off-farm income; (ii) moderate NTFP income, large livestock herds, and high off-farm income; and (iii) low NTFP income, small herds, and moderate off-farm income. Overall, all types of farms showed different livelihood strategies; specific recommendations aimed at increasing sustainability were provided for each type. While both improved forages for livestock and grazing in forests are relevant for all types of farms, in some cases, value-added processing of NTFPs and contributions from off-farm activities such as tourism are necessary for the conservation and sustainable use of forests
