The spatial overlay effect of urban waterlogging risk and land use value.

Urban waterlogging poses a severe threat to lives and property globally, making it crucial to identify the distribution of urban value and waterlogging risk. Previous research has overlooked the heterogeneity of value and risk in spatial distribution. To identify the overlay effect of urban land value and risk, this study employs the Entropy Weighting Method (EM) to assess urban value, Principal Component Analysis (PCA) to determine waterlogging risk and key areas (RK), local Moran's I (SC) to identify key areas (HK), and finally Bivariate local Moran's I (DC) to comprehensively evaluate urban value and waterlogging risk to delineate key areas (BH). The results indicate that waterlogging risk is primarily influenced by proximity to water systems (PCA coefficient: 0.567), population density (0.550), and rainfall (0.445). There is a positive correlation between urban value and waterlogging risk, with a global Moran's I of 0.536, indicating that areas with higher urban value also face greater waterlogging risk. The DC method improved identification precision, reducing the BH area by 6.42 and 3.51 km2 compared to RK and HK, accounting for 25.50 % and 15.76 % of the RK and HK identified areas, respectively. At present, rescue resources can access less than one-third of the area within 5 min, but with the DC method, during the centennial rainfall scenario, the accessibility rate within 5 min for the BH area reaches 63 %, and all BH key areas can be covered within 15 min. This study provides a new methodology for identifying key areas of waterlogging disasters and can be used to enhance urban rescue efficiency and the precision management of flood disasters.

Quantifying intangible values of wetlands as instrument for conservation in the Po delta park (Italy).

Wetlands possess intangible values that are usually overlooked in decision-making processes. Based on questionnaire surveys, this work aims to quantify both the non-use and cultural values provided by the different wetlands of the Po Delta Park (Northern Italy), selected as ideal case study, using willingness to pay (WTP) for wetland conservation and travel cost methods, respectively. Their relationships with socio-economic variables and respondents' preferences for current and future use were also analysed. The 61.39% of participants were willing to pay a mean amount of 95.8 € (±40). The average travel cost was 38.68 € (±6.24), with higher values observed for environmental experts than for other citizens. Wetlands differ significantly in travel costs, current and future use, but not in WTP. Poisson regressions showed that non-use and cultural values were significantly dependent on personal information, preference variables and travel distance. Intangible dimensions, such as bequest and existence values, showed higher valuations/rates than option and direct use values. The results highlight that perceptions of the intrinsic value of nature are influenced by demographic characteristics, distance from the area and desired future uses. Non-use values seem abstract and generalised to the whole area, regardless of the ecological characteristics of the wetland, even though a significant relation to wetland uses was observed. In contrast, cultural values are tied to specific wetlands, as indication of the importance of historical relationships between people and nature. Such findings underline that the different dimensions of intrinsic value of nature may act at different scales and help decision-makers to incorporate such values into environmental accounting.

How do plant demographic and ecological traits combined with social dynamics and human traits affect woody plant selection for medicinal uses in Benin (West Africa)?

BACKGROUND: Several hypotheses have been used in ethnobotany to explain the plant's selection criteria by people for their daily needs. Thus, it is important to assess synergy and complementarity among them, especially, those concerning the plant use value, social dynamics and human traits. The study aims to (i) highlight people's socio-economic factors, and plant ecological traits that affect the plant use-availability dynamic (PUD); and (ii) assess the available species diversity effect on ethno-medicinal knowledge diversity in Benin. METHODS: Ethnobotanical interviews were carried out to quantify the importance of local species in different ecological zones of Benin with 590 traditional medicine actors. Vegetation surveys were done to assess species availability within 337 plots of 50 m x 40 m or 60 m x 30 m, depending on the climatic zone, for a total of 61.6 ha, established in 15 forests distributed within the 10 phytodistricts of Benin. The plant use availability hypothesis was quantified as a dynamic link between species use value and availability (PUD). A general and mixed linear models were used to assess the significance of each factor's effect on PUD. Pearson correlation test was applied on Shannon diversity index considering inventoried species in the field and those which were cited by people, for the available species diversity effect on ethno-medicinal knowledge diversity assessment. RESULTS: A hundred and twenty woody medicinal plants, mostly trees (68.33%), were sampled. Growth form and its interaction with phytodistrict have a significant effect (p: 0.005) on PUD. The less available trees were the most used in the phytodistricts 3, 4, 8 and 10. PUD varies significantly according to social factors (p: 0.007). Ethnicity, age and main activity were the most quoted social factors which influenced the PUD. Ethnicity and age have various effects considering the phytodistricts. Moreover, the influence of age changes following the main activity. Plant selection did not solely link to the surrounding diversity (r: - 0.293; p: 0.403). Within some phytodistricts, especially those of 3, 4, 8 and 10, the less available tree species were the most requested. CONCLUSION: It is urgent to reforest vegetation patches in some phytodistricts (3, 4, 8 and 10) of Benin with widely requested and no available species to avoid the extinction of their wild populations. This concerns Cassia sieberiana DC., Anonychium africanum (Guill. & Perr.) C. E.Hughes & G. P. Lewis, Pterocarpus erinaceus Poir., Cola millenii K. Schum., Azadirachta indica A. Juss., Khaya senegalensis (Desr.) A. Juss., Pseudocedrela kotschyi (Schweinf.) Harms, Treculia africana Decne. ex Trécul, Uapaca heudelotii Baill., Vitellaria paradoxa C. F.

Animal and their products used for treatment and prevention of disease practiced by traditional healers in Jimma Arjo district, East Wollega Zone, Western Ethiopia.

BACKGROUND: Ethiopia is one of the countries with richest fauna used for medicinal purpose. The Jimma Arjo community has knowledge and practice of utilizing this medicinal animal for treatment of human and animal ailments. OBJECTIVE: The objective of this research is to assess animals and their products used for treatment of human and animal ailment METHODS: A cross-sectional ethnozoological survey was conducted using a semi structured questionnaire among purposively selected traditional healers resided in Jimma Arjo district. The data collected was entered in Microsoft excel spread sheet and analysed using SPSS statistical software. Fidelity level (FL), use value and informant consensus factor was determined. RESULTS: A total of 33 animal species was found to be used for treating 40 human ailments and different livestock disease confirmed by 36 informants of different ages, sexes and educational backgrounds. The majority of animals (63.63%) were mammals followed by birds (15.15%). Most of the respondents were male, married and aged 55 years and above. Most of the healers learn ethnozoological practice from the father (36.11%) followed by mother (19.44%). The traditional practice is accepted by (72.22%) of the community where 61.11% of the healers are not willing to transfer their knowledge to other. For most of the healers, the reason to practice traditional healing was for treating one's own family or animals (41.67%). The FL was found 100% for honey from Apis mellifera and Trigona spp. for asthma, Cynopterus sphinx for viral skin disease and Crocuta crocuta for bad sprit treatment. In this study, honey from A. mellifera, Hystrix cristata and Sus scrofa domesticus were reported to cure different ailments. CONCLUSION: This study indicated wide use of medicinal animals and their products which could be used as an alternative and complementary medicine or a basis for in developing new drugs because the existing drugs especially antimicrobials are under threat due to the development of resistance by microbes.

Wild Edible Fruits as a Source of Food and Medicine: A Study among Tribal Communities of Southern Khyber Pakhtunkhwa.

Botanical surveys in all parts of Pakistan are mainly focused on ethnomedicinal uses of plants, and very little attention has been paid to documenting edible wild fruit species (EWFs). Multiple methodologies and tools were used for data collection. In a recent survey 74 EWF species belonging to 29 families were documented, including their medicinal uses for the treatment of various diseases. The most cited (23%) preparation method was raw, fresh parts. The UV and RFC of EWF species ranged from 0.08 to 0.4 and from 0.02 to 0.18, respectively. In terms of specific disease treatments and their consensus, the ICF ranged from 0 to 0.38. Sexual, gastrointestinal, and respiratory disorders had the highest use reports, and 11 species of plants had the highest FL of 100%. On the basis of uses reported by the inhabitants of seven districts of Southern Khyber Pakhtunkhwa Province, the CSI ranged from the lowest 1.3 to the highest 41. It is concluded that the traditional uses of EWF species depend mainly on socio-economic factors rather than climatic conditions or the number of species. However, there is a gradual loss of traditional knowledge among the younger generations. The present survey is the first baseline study about the socio-economic dimension of local communities regarding the use of EWF species for food as well as medicine.

Ethnozoological study of medicinal animals and animals' products used by traditional medicinal practitioners and indigenous people in Motta city administration and Hulet Eju Enessie District, East Gojjam, Northwest Ethiopia.

BACKGROUND: In Ethiopia, many ethnic communities use traditional/indigenous medicine for primary health care. However, this indigenous medicinal practice is being neglected and continued to be lost due to poor documentation as they are transferred from generation to generation through oral tradition. Therefore, this ethnozoological study aimed to assess and document the medicinal use of animals and animals' products used by traditional medicinal practitioners and indigenous people in Motta city administration and Hulet Eju Enessie Districts, East Gojjam Zone, Ethiopia. METHODS: Cross-sectional ethnozoological survey was conducted using a Semi-structured questionnaire among purposively selected respondents in Motta city administration and Hulet Eju Enessie District, East Gojjam Zone, Ethiopia from September 2020 to June 2021 GC. The ethnozoological data were analyzed using SPSS version 26 and Microsoft Excell Spreadsheet. Fidelity level, use-value, and informant consensus factor were determined. RESULTS: A total of 25 animal species were reported to be used for the treatment of different ailments by 33 informants. The majority of animals (64%) were mammals followed by birds (16%). The fidelity level ranged from 18.2 (Hyena for bad spirit) to 100% (stingless be for asthma, Tiger for rabies virus, Whisper for nightmare). CONCLUSION: This study showed the wide use of medicinal animals and their parts/products for meeting the primary healthcare needs of the community in the study area. Therefore, this ethnozoological medicinal knowledge needs to be integrated with modern medicine to use animals/animals' products as a potential source of effective drugs for different ailments.

The relevance of quantitative ethnobotanical indices for ethnopharmacology and ethnobotany.

ETHNOPHARMACOLOGICAL RELEVANCE: As an interdisciplinary field of research ethnopharmacology draws on methodologies and methods from a variety of disciplines. A range of ethnobotanical indices are frequently used to transform primary data obtained through field studies into statistical measures. These indices are claimed to serve as a proxy for efficacy or drug discovery (Fidelity Level 'FL') and to show the importance of botanical drugs and plants used as medicines (Relative Importance 'RI', Use Value 'UV' or Cultural Importance Index 'CI', Cultural Value Index 'CV', Relative Frequency of Citation 'RFC'). This is, however, doubtful, as these indices have not been developed by statisticians, nor by pharmacologists while a proof of concept is lacking. Moreover, the question whether a simple number can summarize the cultural value or importance of plants is not only mathematical but also epistemological. MATERIAL AND METHODS: The FL, RI, UV/CI, CV and the RFC are shortly reviewed. Their statistical rigour is explained and the relevance for ethnobotany, ethnopharmacology and drug discovery discussed. RESULTS: The effect of the sample size on the dispersal of data and the differential probability of botanical drugs being used for the different categories of use are not being considered by these indices. They lack statistical rigour and are simple percentage calculations. Moreover, important factors influencing plant use, such as the availability of pharmaceutical drugs, or the severity of diseases covered by the use-categories, are not accounted for. CONCLUSION: Especially unexperienced and young researchers may be ensnared by using ethnobotanical indices to describe their field data. However, the cultural value and importance of plants in general, and more specifically, of medicinal plants and botanical drugs cannot be summed up by numbers. The discussed indices encrypt parts of the primary data but fail to show the value or importance of plant use because the reasons for which plants are valued or important to people are far more complex than what the formulations of these indices suggest. The indices also lack the power to pinpoint plant species or botanical drugs for drug discovery that contextualized primary data has. Botanical drugs may be useful for a range of disorders or only for specific indications, according to their pharmacologic properties. Therefore, the exclusiveness of therapeutical applications (FL) does not serve as a proxy for effectiveness. The solution is to use and understand the contextualized primary data.

Estimating the recreational value of a coastal wetland park: Application of the choice experiment method and travel cost interval analysis.

Estimating the recreational value of a coastal wetland park is useful in understanding wetland ecosystem and nurturing a balanced relationship between wetland tourism exploration and natural conservation. This study aims to apply appropriate methodologies to accurately estimate the recreational value of a coastal wetland park. The Nansha Wetland in China was used as the study site, and its recreational value was divided into non-use value (estimated using the choice experiment method (CEM)) and use value (estimated using travel cost interval analysis (TCIA)). The data were collected via questionnaires consisting of different choice experiment scenarios and travel cost investigations. The results showed that the per capita and total non-use values were 116.97 CNY/17.80 USD and 24.56 million CNY/3.74 million USD, respectively, and the per capita and total use values were 313.95 CNY/47.79 USD and 65.93 million CNY/10.04 million USD. Therefore, the per capita and total recreational values were 430.92 CNY/65.59 USD and 90.49 million CNY/13.77 million USD. CEM was used to identify tourists' trade-offs and preferences among the selected wetland attributes. As a result, tourists were found to have the largest marginal willingness to pay (MWTP) for "mangrove coverage," followed by "species of rare birds" and "water visibility." TCIA was used to solve the under-dispersion problem of the number of trips. Based on these findings, several managerial implications were identified, including adjusting ticket price based on the non-use value, regulating tourists' behaviors, enhancing the protection of mangroves, improving the water quality and the living habitats of migrant birds, and promoting science education and popularization.

Fauna silvestre con valor de uso en la Reserva de la Biosfera Sierra de Huautla, Morelos, México / Wild fauna with use value in the Biosphere Reserve Sierra de Huautla, Morelos, Mexico

Resumen El objetivo de este trabajo fue sistematizar las especies apropiadas, formas de apropiación y valores de uso asignados a la fauna silvestre en comunidades de la Reserva de la Biosfera Sierra de Huautla, México, mediante un análisis documental y trabajo de campo. Se registraron 46 especies con valor de uso pertenecientes a 31 familias. La clase con mayor número de especies apropiadas son las aves (42.5%), seguidas de los mamíferos (34%). El 64% de las especies se apropian con fines alimentarios y el 38.3% se utilizan para el tratamiento de enfermedades en la medicina tradicional. Otros usos son adornos, amuletos, elaboración de herramientas y como animal de compañía. La apropiación de fauna silvestre se realiza por medio de la cacería, la recolección y la pesca. Las armas de fuego como la escopeta es el principal instrumento para la cacería. También se utilizan perros, machetes, resorteras, tarrayas, anzuelos, nudos corredizos y se capturan manualmente. La apropiación puede ser una actividad oportunista u organizada por medio de las arreadas, espiadas, lampareadas, campeadas, acorralamiento y recolección manual. La apropiación de fauna silvestre es una actividad culturalmente arraigada en las comunidades de la reserva. Sin embargo, el análisis de la relación sociedad-fauna en la región es limitado, por lo que es necesario generar información que promueva el manejo sostenible del recurso faunístico.

Abstract The aims of this paper were the systematization of appropriated species, appropriation forms and assigned use values of wildlife species in the Biosphere Reserve of the Sierra de Huautla, Mexico, by means of documentary analysis and field work. We recorded 46 species with use value pertaining to 31 families. Birds accounted for the highest number of appropriated species (42.5%), followed by mammals (34%). Of the total species, 64% are appropriated for alimentary purposes and are used in the treatment of diseases in traditional medicine. Others are used as ornaments, talismans, in tool manufacture and as pet animals. Wildlife appropriation is achieved by hunting, collection and fishing. Fire arms such as shotguns are the main instrument used in hunting. Dogs, machetes, slingshots, nets, hooks, slipknots, are also used, or they are captured by hand. Appropriation can be an opportunistic or organized activity by means of "arreadas" (herding), "espiadas" (opportunistic observation), "lampareadas" (spotlighting), "campeadas" (scouring), "acorralamiento" (cornering) and manual collection. Wildlife appropriation is a culturally rooted activity in the reserve communities. Nevertheless, the analysis of the relationship society-fauna in the region is limited and this is why the generation of information that may enable a sustainable management of the faunistic resource is necessary.

Ethnomedicinal Plants Used in the Health Care System: Survey of the Mid Hills of Solan District, Himachal Pradesh, India.

The study was performed in the mid hills of the Dharampur region in Solan district of Himachal Pradesh, India. At the study site, a total of 115 medicinal plants were documented (38 trees, 37 herbs, 34 shrubs, 5 climbers, 1 fern, and 1 grass). In the study region, extensive field surveys were performed between March 2020 and August 2021. Indigenous knowledge of wild medicinal plants was collected through questionnaires, discussions, and personal interviews during field trips. Plants with their correct nomenclature were arranged by botanical name, family, common name, habitat, parts used, routes used, and diseases treated. In the present study, the predominant family was Rosaceae, which represented the maximum number of plant species, 10, followed by Asteraceae and Lamiaceae, which represented 8 plant species. The rural inhabitants of the Dharampur region in the Solan district have been using local plants for primary health care and the treatment of various diseases for a longer time. However, information related to the traditional knowledge of medicinal plants was not documented. The rural inhabitants of the Dharampur region reported that the new generation is not so interested in traditional knowledge of medicinal plants due to modernization in society, so there is an urgent need to document ethnomedicinal plants before such knowledge becomes inaccessible and extinct.

Uses, abundance perception, and potential geographical distribution of Smilax aristolochiifolia Mill (SMILACACEAE) on the Totonacapan Region of Puebla, Mexico.

BACKGROUND: In some regions of Mexico, edible wild plants have been displaced or eliminated from the traditional food systems, mainly by changes in land use, booming monoculture, herbicide use, and by changes among the new generations in the traditional foods and diets of indigenous populations. In the Totonacapan region of Puebla, the gradual change from the traditional acahual plantation to coffee-type agroecosystems has provoked the displacement of old-growth forests and the eradication of wild plants since 1970. One of the wild species which has been used in traditional medicine and food recipes by the Totonac culture is Smilax aristolochiifolia (SMILACACEAE), known as "kgentsililh". This species forms part of traditional Totonac recipes, in which the tender stems are still used in local medicine to treat menstrual pain, deal with dysentery, and prevent hair loss. According to the Maxent® Program, there are still potential areas with habitats suitable to promote its conservation in the Poblano Totonacapan. METHODS: We conducted 260 interviews with people in 13 locations in the northern Sierra of the State of Puebla. Variables taken into account in the interview related to the consumption frequency of the species, its abundance and distribution perception, reasons or arguments given by the Totonac indigenous population about the decreased presence of specimens of S. aristolochiifolia, its dates of collection, and the cutting prices of kgentsililh at the community level and in local markets. The relative abundance of S. aristolochiifolia was determined through 22 samples in 2ts of 600 m2. Later, its potential distribution in the state of Puebla was estimated using the Maxent® Program Ver. 3.3.3. RESULTS: Of the 260 Totonac families interviewed, 31% had stopped consuming kgentsililh. The residents reported that in the last 50 years the populations of this plant had diminished in the northern Sierra of the State of Puebla, mainly due to changes in land use, herbicide application, over-collection, and urban growth. In traditional medicine, the stem sap of S. aristolochiifolia is currently employed to help treat baldness, and the "tuberous root" or plant rhizome is used to prepare a tea infusion to treat dysentery. The cost of plant guides varies from 10.00 to 40.00 Mexican pesos for one bunch (around 0.5 to 2.00 US dollars), and every bundle consists of between 7 to 10 cuttings from 0.4 to 0.5 m long. From our 22 quadrats of sampling and collection of S. aristolochiifolia, we were able to recognize a total of 32 specimens. There is a considerable abundance of kgentsililh in acahual plantations and old-growth forests (evergreen lowland and mid-elevation perennial forest) concerning the coffee-type plantations and milpas. According to our analysis using the Maxent Program®, eight physical and climatic variables have a direct relationship to the potential distribution of the species. CONCLUSIONS: Smilax aristolochiifolia is still a plant of socioeconomic importance, mainly because of its food value and its use in traditional medicine by indigenous families in Poblano Totonacapan. It is evident that the villagers perceive that in the last 50 years the species has decreased its population mainly due to land-use change, the application of herbicides to the different family production units, and climate change. At the moment, there is no knowledge about the methods of propagation of the species, and therefore there is no intention on the part of the population to conserve the species. However, it would be of great importance to generate a biocultural conservation strategy and take advantage of the results obtained from the potential geographic distribution area, since according to the Maxent® Program, there are still potential areas with habitat suitable to promote conservation in Poblano Totonacapan.

Ethnobotanical survey of medicinal plant species used by communities around Mabira and Mpanga Central Forest Reserves, Uganda.

BACKGROUND: Medicinal plants form an integral part of many health care systems in Uganda. This study aimed at documenting the therapeutic importance of plant species used in primary health care among communities living adjacent to Mabira and Mpanga forest reserves in Central Uganda. METHODS: An ethnobotanical study was conducted between April and June 2018 in 7 villages adjacent to Mpanga and 6 villages adjacent to Mabira central forest reserves. Information was obtained from 28 respondents identified using snowball and purposive sampling techniques and interviewed using semi-structured questionnaires. Descriptive statistics were used to present the data. The quantitative analysis of data was done using fidelity level, informant consensus factor, and percent respondent knowledge indices. RESULTS: A total of 136 medicinal plants were recorded. The plant species classified into 55 families were grouped under 14 medical categories with the highest number of plant species being used for digestive disorders (44%), followed by respiratory (38%) and dermatological disorders (36%). Hoslundia opposita Vahl was mentioned by 71% of the respondents for treating 22 disease conditions. Plant Family Fabaceae was the most represented with 16 species. Informant consensus agreement was high (0.7) for respiratory disorders. The fidelity level was 100% for Bidens pilosa L. and Callistemon citrinus Skeels for treating wounds and cough, respectively. Plant remedies were mainly prepared by decoction (31%) and administered orally (36%). A large number of plants (61%) were harvested from wild habitats. Herbs (50%) and leaves (50%) contributed the highest percentage of plant biological forms and parts used in remedy preparation. CONCLUSION: This study recorded plant species with the potential to treat a wide range of illnesses. This is reflected in the high diversity of the recorded species used for medicinal purposes. Pharmacological studies on the plants with high percentage use values and fidelity levels are needed to validate their uses in the management of the said therapeutic applications. Further research on the isolation and characterization of the plant active compounds could lead to the discovery of new potential drugs.

Ethnobotanical characterization of medicinal plants used in Kisantu and Mbanza-Ngungu territories, Kongo-Central Province in DR Congo.

BACKGROUND: The phytotherapeutic knowledge of the Kongo people in the territories of Kisantu and Mbanza-Ngungu in Kongo-Central Province (DR Congo) is rapidly eroding. To document the remaining knowledge, we conducted an ethnobotanical survey on the most important medicinal plant species and diseases treated with them, as well as plants with therapeutic potential. We also checked for the cultural similarity in medicinal plant knowledge between the two territories and how knowledge about Kongo medicinal plants differs between different social groups. METHODS: From June 2017 until February 2018 and from February 2019 until April 2019, we conducted a survey with 188 phytotherapists, selected using the snowball method and surveyed using semi-structured interviews. Voucher specimens were taken for identification. Ethnobotanical data were analyzed using medicinal use value (UVs), informant agreement ratio (IARs), informant consensus factor (ICF), and species therapeutic potential (STP). Rahman's similarity index was used for ethno-cultural comparison of medicinal plant knowledge between the two communities. Medicinal knowledge between different social groups was analyzed using non-parametric tests and Poisson regression. RESULTS: A total of 231 plants (i.e., 227 botanical species, representing 192 genera and 79 families) were reportedly used to treat 103 diseases. Most abundant taxa were reported for the Fabaceae family (including 11.9% of species and 10.9% of genera). Most reported species (45.0%) were from anthropized areas. Leaves (39.4%), herbs (37.1%), decoction (41.7%), and oral ingestion (72%) were the most frequently cited plant part, botanical form, preparation, and administration method, respectively. Four of all inventoried species showed high UVS (> 0.05), whereas eight had an IAR of one. According to ICF, 31 diseases were mentioned. Highest ICF (≥ 0.4) was observed for hemorrhoids (0.44), amoebiasis (0.43), and itchy rash (0.42). Fifty-four plant species were identified as likely possessing an interesting therapeutic potential. Low ethno-cultural similarity in medicinal knowledge (RSI = 16.6%) was found between the two territories. Analysis of the Kongo medicinal plant knowledge showed that the mean number of reported species and diseases vary considerably depending on gender, type, and residence of therapists (P < 0.05). CONCLUSION: Results prove that the Kongo phytopharmacopeia makes use of interesting medicinal plant species that could be further studied for conservation and pharmacological applications.

Local preferences for three indigenous oil-seed plants and attitudes towards their conservation in the Kénédougou province of Burkina Faso, West-Africa.

BACKGROUND: Carapa procera, Lophira lanceolata, and Pentadesma butyracea are three underutilized but increasingly threatened indigenous oil-seed tree species (IOS) in tropical Africa. Because local knowledge is vital for sustainable management, this study investigated the socio-economic factors that explain local people's (i) preferences for these IOS, (ii) attitudes toward their conservation, and (iii) ability to identify "plus trees" based on seed traits. We predicted a positive relationship between response variables and informants' age, residence status, gender (femaleness), and existence of market opportunities for each IOS. We also predicted that a higher preference for a given IOS has a positive effect on people's attitudes for its conservation and the aptitude to identify its "plus trees." We additionally expected significant differences among ethnic groups for each response variable. METHODS: Data were collected through individual semi-structured interviews with 336 informants from 14 randomly selected villages in the species distribution area of Kénédougou province. For each species, the collected data were the number of actual uses reported (converted to use value-UV, as a measure of the species preference), practiced conservation actions (converted to conservation attitude using a four-scale scoring method), and possible criteria for selecting preferred trees for seed oil extraction. Generalized linear mixed models were used to test for the fixed effects of socio-economic factors, and account for the random variation across villages. RESULTS: The results showed species-specific patterns. Carapa procera had the highest UV and hence was the most preferred IOS, particularly by women. Informants from the Siamou ethnic group had the highest UV irrespective of IOS. The most cited conservation actions were assisted natural regeneration and banning of tree cutting, which were practiced for C. procera and L. lanceolata. No conservation measure was cited for P. butyracea. The practice of tree planting was not recorded for any of the IOS. Young and male informants participated less in conservation actions. Tree selection for oil-seed collection was mainly guided not by "oil extraction yield" but rather by the "quality of extracted oil" (namely oil color and taste for food uses, and oil bitterness for medicinal efficacy). The selection mainly concerned L. lanceolata and was mostly practiced by elderly people. CONCLUSION: This study provided useful local knowledge-based information to guide conservation actions and valorization strategies of three IOS. The study sheds further light on the socio-economic factors that are associated to local people's preferences, conservation attitudes, and individual tree selection.

Nomenclatura y usos del culantro de monte (Eryngium foetidum L) en la comunidad San Antonio de Padua, cantón Quinsaloma, Provincia de Los Ríos ­ Ecuador / Names and uses of the Culantro de Monte (Eryngium foetidum L) in the San Antonio de Padua community, Los Ríos ­ Ecuador

Culantro de monte (Eryngium foetidum L.) is a biennial herb of tropical origin very frequent in America, Africa and the Caribbean. With the arrival of Europeans in the fifteenth century, it managed to be distributed to various locations in Asia and Europe. The present study was carried out in the San Antonio de Padua community in the Province of Los Ríos - Ecuador to collect information, through interviews with the residents, regarding the nomenclature and uses of this aromatic herb. It was found that 52% of the interviewees mention a nutritional use, especially as a condiment for fish soup, buns and stews, while 26% say they use this plant for medicinal purposes in infusions to cure stomach and joint pain. The variety of metabolites that it possesses, such as eryngial (E-2-Dodecenal), extends its range of applications in modern medicine. We concluded that the transfer of ethnobotanical information still remains in the community, but the young generations are unaware of several of this plant's applications.

Exploitation of ethnoecologically important wild trees by two ethnic groups in a community-based Hippopotamus Sanctuary in Northwestern Ghana.

Use of wild tree species by smallholder farmers for various purposes is crucially important for their daily livelihoods. However, the growing demand for these natural resources could lead to their overexploitation and environmental change. The aims of this ethnobotanical research in the Wechiau Community-based Hippopotamus Sanctuary (WCHS) were to i) document wild tree species, uses and analyze their cultural importance, ii) investigate socio-demographic variables of smallholder farmers influencing their traditional knowledge on wild tree species and uses, and iii) examine smallholder farmers ' perceptions about the establishment of the WCHS. To attain the above-stated aims, 135 smallholder farmers were interviewed in nine villages belonging to the Waala and Birfor ethnic groups. The primary data were subjected to rigorous statistical analysis (using Cognitive Salience index reflecting cultural importance, univariate and use value analysis). Given the results of this study, the WCHS is enriched with 43 ethnoecologically important wild tree species belonging to 22 families and 41 genera. This study showed that eight topmost wild tree species in descending order of cultural importance included Vitellaria paradoxa, Burkea Africana, Diospyrous mespiliformis, Bombax costatum, Parkia biglobosa, Pterocarpus erinaceus, Terminalia avicennioides and Acacia gourmaensis. It is also established in this paper that the family cultural importance for Fabaceae and Sapotaceae is predominantly high as reflected in the frequency and ranking of citations of wild tree species under these families by local informants. The 43 wild tree species cited by local informants were categorized into nine different uses including food (9 species), forage (30), firewood (40), medicine (6), construction (9), soil improvement (3), social use (2), gardening (5) and fiber/ropes (2). Among these use categories, firewood, forage, food and construction topped the list as the most culturally important to the smallholder farmers. It is also revealed that the traditional knowledge on varied wild tree species and their uses was significantly affected by age of smallholder farmers (ps < 0.05), but not ethnicity and other factors. This study thus suggests the need for community-based conservation measures for sustainable management of natural resources for rural livelihood improvement in the tropics and sub-tropics.
