Background: Ethnobotanical knowledge about plant roles in fisheries is crucial for sustainable resource management. Local ecological knowledge helps understand dynamics of the lake ecosystem. Fishers use plants based on availability and characteristics while adapting to the changes in the environment. Studying fishery related uses of plants and algae and the challenges interconnected with them from local perspectives can provide insights into their beneficial uses and impacts to the ecosystem. Methods: The study investigates the botanical knowledge of three fishing villages in Laguna Lake or Laguna de Bay (LB), Philippines, including Buhangin, Sampiruhan, and Mabato-Azufre, each with varying degrees of industrialization. The ethnobotanical study, which gathered 27 interviews between June 2022 and July 2024, included plant collection with the help of local collaborators, including local fishers as research guides. Results: Fishers in LB highlighted positive and negative plant-fishing interactions. The most frequently mentioned plant applications were fish habitat and fish hiding places. Fish food, spawning sites, conservation, and a number of challenges such as navigational concerns and aquaculture fish deaths had been previously reported in local use reports. The remaining observations provide new insights into plant-fishing interactions, including indicators of food quality and food sources for fish, the decrease in the action of waves, and how plants help in improving the quality of the water. Conclusion: These results highlight that the knowledge of fishers regarding the ecosystem in which they conduct their fishing activities provides baseline information about the positive and negative relationships between plants and fishing activities in the region, which is vital for further understanding its biodiversity and ecosystem interactions. It is crucial to consider fisher knowledge and involve them as equal partners in conservation efforts of LB. [ABSTRACT FROM AUTHOR]

Urbanization is a complex and multifaceted process studied across various scientific disciplines. However, in ethnobiology, research on the impacts of urbanization on local ecological knowledge (LEK) often lacks standardization and tends to focus primarily on local scales. This study aims to systematically characterize how researchers address urbanization in ethnobiology and assess its effects on LEK globally. We conducted a systematic review using the PRISMA protocol and selected 66 studies from the Web of Science and Scopus databases for analysis. Our findings reveal that researchers often do not adopt a consistent definition of urbanization, frequently framing their study areas within a simplistic urban–rural dichotomy. Although some studies used urbanization indicators, our qualitative analyses, including a correlation matrix, showed that these indicators were largely independent of each other. Additionally, principal component analysis (PCA) with clustering identified four groupings among the indicators, yet with low correlations between them. A t test analysis of the 66 papers shows that urbanization generally has a negative impact on LEK. Based on these findings, we emphasize the critical need for standardized urbanization indicators in ethnobiological studies and propose a new approach for characterizing urbanization, which will enhance the precision and relevance of future research in this field.

Societal Impact Statement Summary Plant awareness disparity is a widespread phenomenon in modern societies. It erroneously implies that plants are not necessary for humans. Understanding what plants people know and can describe is crucial for evaluating one of four central aspects of plant awareness disparity. This study proposes a new methodology for assessing the knowledge of plants online by analysing the vocabulary used to name and describe plants. Despite the high number of listed plants, both names and vocabulary used to describe plants were homogenised and limited. Educational effort is needed to enhance plant vocabulary so that plants can become the subject of conversation. This study addresses the methodological gap in plant awareness studies by examining adult knowledge of plants from eco‐semiotic and quantitative linguistic perspectives. Understanding what plants people know and can describe and how they do this is crucial for bridging the gap in plant knowledge and addressing plant awareness disparity. The novel methodology involved analysing responses from an online questionnaire distributed to residents of Tartu, Estonia. The questionnaire covered various aspects of plant knowledge, including the ability to list, describe and explain the importance of different plant categories: wild trees and shrubs, wild herbs and cultivated trees and shrubs. Data analysis included word count, contextual analysis and mapping of plant‐related vocabulary used by participants. The study found significant diversity in the plants named by 149 adult participants, with 74 wild tree taxa and 225 wild herb taxa mentioned. Cultivated trees and shrubs were also widely recognised (168 taxa). Most descriptions focused on plant parts such as leaves and flowers, demonstrating rather poor vocabulary. The analysis highlighted the influence of personal experiences, cultural practices and educational background on plant knowledge. The results indicate robust plant knowledge among the study's participants, likely influenced by Local Ecological Knowledge and comprehensive school curricula on botany. However, the study also detected a homogenisation of plant knowledge, potentially due to educational and popularisation efforts. The methodology demonstrated the potential of using linguistic analysis to understand plant knowledge and awareness, offering insights into enhancing plant‐related education. [ABSTRACT FROM AUTHOR]

Simple Summary: In a mountainous area of northwest Namibia, known as the Northern Highlands, community game guards have many years of experience in monitoring local wildlife. But until our study there had been no published research specifically on the elephants in the Northern Highlands. The area is highly remote, and the steep, rocky landscape makes traditional monitoring methods difficult for this small population of elephants, both in terms of on-the-ground tracking and aerial surveys. We identified that an alternative approach of estimating the size of the elephant population could be to gather local ecological knowledge of game guards. From this method, we estimated that there are between 78 and 212 elephants in the Northern Highlands, with a best estimate of 128. We identified how the method could be improved and conclude that it would be applicable for longer-term ecological monitoring of trends in population. This cost-effective approach would supplement other approaches such as aerial surveys that can only provide a snapshot of the population estimate once every five years, because of the high costs. The long-term monitoring would be important to inform the planning of adaptive strategies for the protection of elephants, an endangered species. In planning and monitoring measures to protect wildlife in an area, it is important to have a reliable baseline estimate of population size and trends. There has been minimal published information on a small population of elephants, a keystone and endangered species, in a large area west of Etosha National Park in Namibia, known locally as the Northern Highlands. It is a highly remote, mountainous area in which it is difficult to count elephants. It is semi-desert, where the protection of wildlife is at increasing risk from climate change events, and research on the elephant population is a priority. We interviewed 34 community game guards in the Northern Highlands, focusing on the number of elephants and distinguishing features in known groups. Based on the collated knowledge, and analysis to reduce double counting of known groups, we estimate that there are between 78 and 212 elephants in the Northern Highlands, with a best estimate of 128. The wide range is an indication of the current uncertainties in the method. However, we conclude that this low-cost method, if adapted based on lessons from this pilot study, would be applicable for longer-term ecological monitoring in areas that have a low population density.

Though widespread and categorized as least concern by the IUCN Red List, Reeves's butterfly lizard (Leiolepis reevesii) is considered critically endangered in China. Up-to-date data are warranted to inform future assessments and conservation measures. Through local ecological knowledge surveys and corroborated by field surveys, we discovered an undocumented L. reevesii population on Qi'ao Island of Zhuhai City, Guangdong Province, China. This discovery is the first record of the species in the Pearl River Delta since the early 2010s and represents the only remaining population from the vicinity of its type locality. It was reported to be very rare on the island now and has been extirpated from most of its previous range due to overharvesting, habitat loss and degradation. Our findings also raised concerns about the erosion of local ecological knowledge among local communities. Urgent conservation action and education campaigns are required to prevent further declines and raise awareness of this important and threatened population.

The global food production system is increasingly strained by abrupt and unpredictable weather events, which hinder communities' ability to adapt to climate variations. Despite advances in meteorological predictions, many communities lack the academic knowledge or infrastructure to interpret these complex models. This gap highlights the need for solutions that make climate forecasts more accessible and actionable, especially for communities reliant on natural resources. This study explores the potential of enhancing seasonal climate forecasts by integrating local ecological knowledge (LEK) with scientific data. Specifically, we combined ethnobiological information gathered between 2022 and 2024 with existing oceanographic and ecological data to create an ethnobiological calendar for four fishing cooperatives. An ethnographic approach was used to understand the population's ethnobiological knowledge and their perceptions of marine heatwaves and climate change impacts. Coastal monitoring data was collected using moorings that recorded temperature over a 14-year period (2010–2024). To characterize giant kelp dynamics, we used an existing dataset of multispectral Landsat images, which estimates the surface canopy biomass of giant kelp forests. Ecological monitoring was conducted annually every summer from 2006 to 2023 to record the in situ abundance of ecologically and economically important invertebrate and fish species. Combining oceanographic, ecological, and ethnographic data, allowed for alligning fishers' observations with recorded marine heatwave events and ecological shifts. Our findings revealed that these observations closely matched documented marine heatwave data and corresponding ecological changes. The integration of LEK with scientific oceanographic data can significantly improved our understanding of dynamic climate regimes, offering contextually relevant information that enhances the reliability and utility of seasonal climate forecasts. By incorporating yearly data into an ethnobiological calendar, we promote more inclusive, community-based approaches to environmental management, advocating for the integration of LEK in climate adaptation efforts, emphasizing its crucial role in strengthening resilience strategies against climatic shocks.

One of the essential elements of sustainable fishing technology management is local ecological knowledge (LEK). LEK provides valuable insights into fishing grounds, fishing gear, and target species, passed down through generations of experience. This study employed a Systematic Literature Review (SLR) approach, a methodological framework for conducting comprehensive and transparent literature reviews based on the preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. This study aimed to evaluate the application of LEK in fishing technology by focusing on three aspects: fishing grounds, fishing gear, and target species. Data were gathered from peer-reviewed journals in the Scopus database covering the years 2018 to 2023. The results indicate that LEK is instrumental in identifying fishing grounds, selecting and utilizing fishing gear, and locating target species that hold ecological and economic value. Integrating LEK with modern science can lead to more effective and sustainable fisheries management policies, addressing the current lack of documentation, scientific recognition, and integration of LEK within contemporary scientific frameworks.

Earth's forests are continually monitored by both the satellite record and the lived experiences of nearly 2 billion forest‐proximate peoples. Generally, the satellite record summarizes production estimates, such as percent tree cover, at regular, relatively coarse scales. Conversely, local perceptions tend to capture changes at irregular and very fine scales. While the utility of both of these sources of information has been widely demonstrated in isolation, little work has explored in what contexts they are expected to correlate or deviate, or how they might be quantitatively integrated. Here, we collect gridded information on community perceived and remotely sensed mangrove cover change across 719 0.5‐km grids in Pemba Island, Tanzania. We reveal variation in the association between these two data sources across different wards (shehia) and explore the reasons for this variation using interviews and direct observation. We find that shehia with the greatest alignment between perceived and remotely sensed mangrove change tended to have little planting or natural regeneration of mangrove propagules and large areas of complete cover loss. Alternatively, in shehia with the lowest alignment, we find high levels of natural and/or human‐assisted mangrove recolonization and selective harvesting of individual trees and branches. These findings indicate that the alignment between local knowledge and satellite observations of mangrove cover change systematically increases with the scale of change in this system. Finally, we demonstrate a practical workflow for quantitatively leveraging these misalignments by optimizing across both data sources to identify restoration priority areas. [ABSTRACT FROM AUTHOR]

Urban foraging practices are increasingly recognized as important components of metropolitan food systems, yet there are still knowledge gaps regarding the factors influencing wild edible plant use in urban contexts. Here, I examined the socio-ecological dynamics of wild edible plant use in the metropolitan area of Valparaíso, Chile. Through ethnobotanical surveys and ecological sampling, I characterized the current assemblage of wild edible plant species utilized by urban inhabitants, documenting patterns of use dominated by exotic taxa. Results revealed that family background, particularly rural connections and parental foraging practices, significantly influenced individuals’ engagement with wild edible plants. Abundance and frequency of occurrence, indicators of plant availability, were stronger predictors of use than biomass, a measure of plant productivity. Examination of knowledge transmission pathways highlighted the persistence of traditional family-based sources alongside the adoption of modern information channels. The study also revealed that cultural heritage, plant availability, and knowledge transmission work together to shape foraging practices in urban settings. This research highlights the need for interdisciplinary approaches in addressing the challenges and opportunities presented by urban foraging in the Anthropocene. [ABSTRACT FROM AUTHOR]

Abstract Background The ethnobotanical analysis of two bordering areas allows for the in-depth understanding of the dynamics of Local Ecological Knowledge, which mirrors the naturalistic, historical, and sociopolitical features of each area. As part of the Interreg Italy-Switzerland B-ICE&Heritage and GEMME projects, this work is an ethnobotanical comparative study of two neighboring Alpine territories: Valmalenco (Italy) and Valposchiavo (Switzerland). Methods A total of 471 informants were interviewed on different fields of use (medicinal, food, veterinary, etc.). All data were organized in Excel™ spreadsheets. Informant Consensus Factor was calculated for the pathologies reported. Jaccard’s similarity indices were calculated to compare the Valmalenco and Valposchiavo areas. Subsequently, another comparison between Valmalenco/Valposchiavo and Italian/Swiss Alpine neighboring areas was carried out. Results The number of taxa for Valmalenco was 227 (77 families) and 226 in Valposchiavo (65). Out of the 10 most cited species, 7 were mentioned in both. Arnica montana L. was the most cited in Valmalenco, and Sambucus nigra L. in Valposchiavo. The 5 most cited families were the same. Regarding the medicinal and food fields, the similarity indices were fairly low (0.31 and 0.34 for the species; 0.22 and 0.31 for the uses). Concerning the comparison with Italian and Swiss Alps, similarity values were slightly higher with Italy (Valmalenco food species: 0.38 with Italy and 0.26 with Switzerland, medicinal: 0.26 IT and 0.14 SW; Valposchiavo food species: 0.36 with IT and 0.26 with SW, medicinal: 0.21 IT and 0.14 SW). Conclusion Although Valmalenco and Valposchiavo partly share natural environment, language, history, and culture, they had low similarity indices. They both seemed to have more similarities with Italy than Switzerland, maintaining low values with the surrounding territories too. They showed a common core of Local Ecological Knowledge with several divergent branches possibly due to pivotal historical happenings, as well as more modern external influences.

Abstract Background Hybridization between the local medical systems (LMSs) and biomedicine has been the focus of different studies in ethnobiology, primarily due to the increasing access to biomedicine by indigenous peoples and local communities. Studies on hybridization allow for an understanding of the process of developing and evolving local knowledge systems. In this study, we propose a hybridization score to determine how individuals’ socioeconomic characteristics and preference between LMS and biomedicine determine the complementarity of therapeutic options. Methods We conducted semistructured interviews and applied free listing technique in a rural community in Northeast Brazil to assess the treatments the local population sought and which were preferred. Results Our analyses showed that the level of schooling was the socioeconomic factor that negatively affected the hybridization process. Individuals with higher levels of schooling tended to prefer LMS strategies less and, consequently, showed a lower probability of hybridizing the two systems. Additionally, older people who preferred LMS strategies showed a greater tendency to adopt hybridization in human health-seeking behavior. Conclusions Our findings provide further evidence of the complementarity between different medical systems and demonstrate that socioeconomic factors can affect local knowledge and are responsible for differences in individual propensity to hybridize distinct medical systems.

Living with wildfires in an era of climate change requires adaptation and weaving together many forms of knowledge. Empirical evidence of knowledge co-production in wildfire management is lacking in Mediterranean European areas. We explored how local ecological knowledge can be leveraged to reduce wildfire risk through an adaptation pathways process in the Montseny massif and wider Tordera River watershed of Catalonia, Spain: an area stewarded through forestry and agriculture, tourism, nature conservation, and fire management. We combined different methods (e.g., a timeline and Three Horizons framework) throughout three workshops with agents of change to co-create adaptation pathways to reduce wildfire risk, integrating a historical perspective of the landscape while envisioning desirable futures. Our results showed that local ecological knowledge and other soft adaptation strategies contribute to innovative sustainable development initiatives that can also mitigate wildfire risk. The adaptation pathways approach holds much potential to inform local policies and support wildfire-based community initiatives in diverse contexts. [ABSTRACT FROM AUTHOR]

Greater Caribbean manatees Trichechus manatus manatus face complex conservation challenges throughout their distribution range, many of which are associated with human factors; and in consequence, the subspecies is considered Endangered (EN) by the International Union for Conservation of Nature (IUCN). Human‐related threats as hunting for meat consumption, collisions with boats, entanglement in fishing nets, pollution and loss of habitat put the Greater Caribbean manatee at risk in Colombia. Studies aiming to describe traditional knowledge and local perceptions provide information that can be useful to design local manatee conservation programmes. We analyse the fishers' perceptions regarding manatees in Ayapel, Córdoba. One hundred semi‐structured interviews were conducted, focusing on personal data, fishing practices, perceptions and knowledge about the manatees. According to the interviews, bycatch is the greatest threat to manatees (56%), followed by pollution (16%), whereas boat collisions (12%), hunting (11%) and drought (5%) are lower ranking threats. Our results demonstrated that participants have a good understanding of manatee biology and ecology. However, a human–manatee conflict was evidenced, as 39% of fishers consider that manatees negatively impact fishing by competition for the fishing resources and/or by damaging fishing gear. We recommend strengthening awareness about the importance of manatee to guarantee an optimal management of this subspecies and its habitat. Fishers should be directly involved in the formulation of management and conservation plans for the subspecies, as their knowledge becomes critical to understanding and mitigating the risks to manatee populations. This work has a clear application to understand the human factor in manatee recovery not only in our study area but also in other locations where manatees share habitat with people, particularly in marginalized human communities.

The ecological apparency hypothesis tests how humans select plants. It is important to distinguish whether an "apparent" plant is the ecologically dominant species or simply the one perceived as most available by people. Additionally, plants' evolutionary history influences their prevalence and human preference, based on shared traits and common ancestors. Thus, considering evolutionary history can tease apart factors that drive the use of plants by humans. Here, we investigated whether the perceived availability of plants is a better predictor of their use value than phytosociological parameters. We estimated rural farmers' perception of the availability of the most important woody species locally and carried out a phytosociological survey in the surrounding forest fragments. We incorporated the phylogenetic relationships among useful species to shed light on the potential effect of plant shared ancestry on the use value. We observed that the availability perception of resources is more crucial in predicting the use value of species than their ecological availability, even when accounting for phylogenetic relatedness. Our findings suggest that use value in ethnobiology is closely linked to perceived resource availability, and it may impact our comprehension of the ecological apparency hypothesis.

As formal education is increasingly valued among rural and Indigenous communities, a common assumption is that local ecological knowledge may simultaneously become devalued or lost. To solve this, several scholars point out that using ethnobotanical knowledge to teach science can be a great way to engage students and help them learn scientific concepts in a more meaningful way and develop a deeper appreciation for their local environment and culture. Through a school herbarium project in three rural schools in western Mexico, students developed different activities, experiments, and applied ethnobotanical tools in order to learn about plant science. A total of 39 wild edible species were collected by students, from which they obtained information about their local name, seasonality, preparations, where they could be found and uses other than food. As the students developed the different activities of the school herbarium project, they not only shared their prior knowledge but were also able to expand that knowledge with scientific information and value into their own ethnobotanical knowledge by learning in accordance with cultural context. The use of ethnobotany as a tool to teach science proved to be a good way not just to learn scientific concepts in a contextualized way but also to revitalize the local ethnobotanical knowledge.

Widely accessible education on edible wild plants is increasingly in demand as more people search for ways to explore wild culinary uses. Despite this growing trend of nature exploration, few scholars have investigated the contribution of this new mode of engagement to human–nature connection and pro-environmental attitudes. Therefore, this research aims to explore the societal role of such foraging educators. Through convenience and snowball sampling, we recruited 31 foraging educators across Europe. Through semi-structured interviews, we inquired about their sources of knowledge, modalities of transmission and their roles as educators. The interviews revealed individuals who convey ethnobotanical knowledge to improve human–nature connection through experiences within nature. The educators gained their knowledge through written sources, vertical and horizontal sharing. Finally, foraging educators consider themselves social bridges of ecological knowledge, bringing scientific ethnobotanical information to a varied audience in an experiential way. Foraging stimulates the sharing of ecological knowledge, and it could be seen as a broader agroecological practice, enhancing the benefits of nature's contribution to people. There is great potential for emerging environmental education platforms and, correspondingly, for rethinking the food system. [ABSTRACT FROM AUTHOR]

Shellcraft is a livelihood activity that utilizes shells and skeletal remains of marine taxa for producing ornamental and decorative items. Despite an increasing importance of shellcraft in coastal areas of the Indo-Pacific region, information necessary for stakeholders to identify and respond to change through policy and management decisions is often lacking for fisheries that support this activity. To address this knowledge gap, a quantitative approach was taken to evaluate social-ecological factors (the what, where, how much, who, when, how, how often, and how long) in a "shellcraft fishery" centered at the Nusa Islands of Papua New Guinea. More than 151,100 individuals across 69 marine taxa were fished annually for shellcraft at the Nusa Islands; fishing was infrequent and quantities fished were low for most taxa when compared with other small-scale fisheries. Fishing most taxa had no association with the main demographic divisions within households although, in terms of participation and catch richness, women were the main actors. Gleaning, combing, and free-diving were the only fishing techniques used, with taxa primarily fished by gleaning intertidal habitats during the day. To contextualize sustainability of this fishery, local ecological knowledge-based perceptions of stock status for the marine taxa fished were examined. Considerations for governance, which included synthesis of existing regulatory measures and aspirations, are also discussed. Since shellcraft occurs throughout the Indo-Pacific region and there are commonalities in taxa utilized, this study provides a basis for comparative analysis of shellcraft fisheries within the region.

Fungi have been used for medicinal purposes for many centuries. This study, based on 35 historical written sources and 581 in-depth semi-structured interviews from eight countries in the western borderlands of the former Soviet Union, investigates the medicinal use of fungi by local communities. We compared the taxa and uses obtained from fieldwork and historical sources with works that advocated fungi use within Soviet herbals, representing the centralised medical system. During fieldwork, we identified eight locally used fungi and one lichen. The highest numbers of medicinal uses were documented in Russia, Estonia and Ukraine. Studies published before the Soviet era listed 21 fungal taxa and one lichen species used in the study region. However, only six of these taxa were mentioned as used by people in our field studies (Amanitamuscaria, Boletusedulis, Lycoperdon, Morchella, Phallusimpudicus and Cetrariaislandica). Notably, these same six taxa were consistently endorsed in Soviet herbals. Of the remaining three taxa recorded in the fieldwork, none were mentioned in historical written sources. However, they were promoted either in Soviet herbals (Inonotusobliquus, Kombucha) or later popular publications (Cantharelluscibarius). This highlights the significant influence of written sources on the use of fungi for medicinal purposes within the studied local communities. [ABSTRACT FROM AUTHOR]

Local knowledge (LK) is often overlooked in the decision-making process during landscape restoration process. In this study, we focus on the Zicuirán-Infiernillo Biosphere Reserve as a case study. We propose a framework to incorporate LK into public policy instruments for implementing restoration interventions in Mexican protected natural areas (PNAs). Through semi-structured interviews, participant observation, and informal talks, conducted with residents from two communities located in the buffer zone and the border area of the reserve, we gathered valuable insights regarding the following: (1) the inhabitants' LK of the ecology and contributions of tropical dry forest, (2) the socioeconomic and environmental issues identified by these communities in their localities, (3) ecological and socioeconomic actions suggested by the residents to recover the forest or halt its degradation, and (4) the role of institutions and local organizations in restoration and conservation processes. Our findings indicate that residents recognized changes in species distribution and identified native trees that are tolerant to drought. Moreover, they acknowledged the beneficial contributions provided by forests, including climate and water cycle regulation, oxygen supply, and raw materials. Local people also demonstrated their awareness of environmental and socioeconomic issues and proposed activities to reverse vegetation cover loss and halt forest degradation. While reforestation emerged as the primary solution for forest recovery, assisted natural regeneration and natural regeneration were also suggested. Based on our results, we propose a framework that emphasizes a robust knowledge exchange among stakeholders, for facilitating the inclusion of LK in an ecological restoration-based education program. It is crucial for Mexican public policy instruments operating in PNAs to consider local knowledge to enhance the effectiveness of ecological restoration.

Abstract Earth's forests are continually monitored by both the satellite record and the lived experiences of nearly 2 billion forest‐proximate peoples. Generally, the satellite record summarizes production estimates, such as percent tree cover, at regular, relatively coarse scales. Conversely, local perceptions tend to capture changes at irregular and very fine scales. While the utility of both of these sources of information has been widely demonstrated in isolation, little work has explored in what contexts they are expected to correlate or deviate, or how they might be quantitatively integrated. Here, we collect gridded information on community perceived and remotely sensed mangrove cover change across 719 0.5‐km grids in Pemba Island, Tanzania. We reveal variation in the association between these two data sources across different wards (shehia) and explore the reasons for this variation using interviews and direct observation. We find that shehia with the greatest alignment between perceived and remotely sensed mangrove change tended to have little planting or natural regeneration of mangrove propagules and large areas of complete cover loss. Alternatively, in shehia with the lowest alignment, we find high levels of natural and/or human‐assisted mangrove recolonization and selective harvesting of individual trees and branches. These findings indicate that the alignment between local knowledge and satellite observations of mangrove cover change systematically increases with the scale of change in this system. Finally, we demonstrate a practical workflow for quantitatively leveraging these misalignments by optimizing across both data sources to identify restoration priority areas.

Abstract Background Understanding how Local Ecological Knowledge (LEK) evolves over time is crucial for fostering social and environmental responsibility. This study aims to develop a conceptual model of plant knowledge circulation, providing insights into the temporal dynamics of LEK in the Polish-Lithuanian-Belarusian border region. It explores the key patterns and driving forces behind changes in the use of wild plants for food. Methods Field research was conducted in 60 rural settlements across Podlasie Voivodeship (Poland), Vilnius Region (Lithuania), and Hrodna Region (Belarus). This included 200 semi-structured interviews and participant observation among two local communities, Lithuanians and Poles. To assess the temporal dynamics of wild food use, we performed a cross-ethnic, cross-border analysis over time, dividing the data into three major temporal dimensions: past, continuous, and recently acquired uses. Results Of the 72 wild plant taxa reported by Poles or Lithuanians in the Polish-Lithuanian-Belarusian borderland, 47 were continuously used for food, 58 were utilised in the past, and 41 were recently acquired. Cross-country trends were similar, with Poland showing more past uses. Diachronic comparisons between Poles and Lithuanians in each studied country revealed no significant differences. Recently acquired taxa overlapped considerably with those used continuously and in the past. The most diversely utilised taxa showed the greatest overlaps. By observing the movement of specific plant taxa within various time dimensions, we distinguished overlapping flow variations: retention (3 taxa), decay (11), invention (8), stagnation (17), revitalisation (6), re-invention (3), and knowledge in motion (24). Shifts in the use of wild food plants were influenced by changes in environmental conditions, governmental policies, cultural practices, and economic factors. Conclusion The findings of this study have important implications for improving methods of tracking changes in LEK and enhancing our understanding of the relationship between people and nature. Our results underscore the importance of considering knowledge circulation over time in different directions. Recognising the various stages of knowledge circulation might help in pursuing sustainable solutions that balance the needs of human communities with environmental protection.

The Critically Endangered Cantor's giant softshell turtle Pelochelys cantorii is a freshwater turtle found in South and Southeast Asia. Its population is declining because of habitat destruction and alteration, and hunting for its meat. Data on the species’ ecology, behaviour, population size, distribution and threats are limited, and previous surveys undertaken in India have failed to detect individuals in the wild. This lack of data hinders strategic conservation planning. Ecologists and conservationists increasingly utilize local ecological knowledge to determine the status and gain insights into the ecology of threatened and rare species that are difficult to detect in field studies. To examine the historical and current occurrence of Cantor's giant softshell turtle, we conducted community interviews along the Chandragiri River in Kerala, India. With data from these interviews, we identified multiple sites where the species continues to occur. Older respondents and those that used the river for fishing and irrigation were more likely to report sightings of the species. Our findings also improved knowledge about the turtles’ seasonal and diel activity patterns. A network of key informants identified through the interviews provided information on turtle bycatch, sightings and nesting. This network is being utilized for the continued monitoring of the species and could help in devising evidence-based management strategies for softshell turtles in India. These methods can also be adopted more widely for other threatened species of freshwater turtles globally.

Riparian ecosystems are faced with a variety of anthropogenic and climate change induced threats which undermine their ability to provide goods and services to sustain livelihoods. The main objective of this paper is to explore local ecological knowledge on the impacts of climate change and variability on riparian based ecosystem services in semi-arid parts of Zimbabwe. The research adopted a mixed approach involving participatory rural appraisal comprising ward level focus group discussions, key informant interviews, household questionnaire surveys, and field observations. Three districts (Chiredzi, Mbire, and Mwenezi) located in drought-prone arid parts of the country were purposively selected for the study. Data were analysed using Excel and R software. Rainfall trend test results for the three districts show significant changes for the wet season months October (p = 0.000), November (p = 0.034), January (p = 0.005) and February (p = 0.001); and for the dry season months June (p = 0.02) and July (p = 0.035). Household respondents reported that they were mostly exposed to high risk from drought, prolonged dry spells and late rains across with subsequent decrease in river flow for the sampled rivers. The riparian zone has seen a remarkable decrease in provisioning ecosystem goods and services over the past 5 years due to climate change, for instance fish from the river have decreased. Findings from cross-tabulations indicated that a total of 363 (60 %) females perceivedclimate related hazards imposed a high impact on provisioning services.. On the other hand, Chi-square results show that respondents’ knowledge of the impacts of climate risks on provisioningl services is significantly influenced by gender (p = 0.01). Future work should focus on community participatory mapping and monitoring of ecosystem goods and services and ecological status of the riparian zone, with potential for restoration of the habitats.

Background: Understanding how Local Ecological Knowledge (LEK) evolves over time is crucial for fostering social and environmental responsibility. This study aims to develop a conceptual model of plant knowledge circulation, providing insights into the temporal dynamics of LEK in the Polish-Lithuanian-Belarusian border region. It explores the key patterns and driving forces behind changes in the use of wild plants for food. Methods: Field research was conducted in 60 rural settlements across Podlasie Voivodeship (Poland), Vilnius Region (Lithuania), and Hrodna Region (Belarus). This included 200 semi-structured interviews and participant observation among two local communities, Lithuanians and Poles. To assess the temporal dynamics of wild food use, we performed a cross-ethnic, cross-border analysis over time, dividing the data into three major temporal dimensions: past, continuous, and recently acquired uses. Results: Of the 72 wild plant taxa reported by Poles or Lithuanians in the Polish-Lithuanian-Belarusian borderland, 47 were continuously used for food, 58 were utilised in the past, and 41 were recently acquired. Cross-country trends were similar, with Poland showing more past uses. Diachronic comparisons between Poles and Lithuanians in each studied country revealed no significant differences. Recently acquired taxa overlapped considerably with those used continuously and in the past. The most diversely utilised taxa showed the greatest overlaps. By observing the movement of specific plant taxa within various time dimensions, we distinguished overlapping flow variations: retention (3 taxa), decay (11), invention (8), stagnation (17), revitalisation (6), re-invention (3), and knowledge in motion (24). Shifts in the use of wild food plants were influenced by changes in environmental conditions, governmental policies, cultural practices, and economic factors. Conclusion: The findings of this study have important implications for improving methods of tracking changes in LEK and enhancing our understanding of the relationship between people and nature. Our results underscore the importance of considering knowledge circulation over time in different directions. Recognising the various stages of knowledge circulation might help in pursuing sustainable solutions that balance the needs of human communities with environmental protection. [ABSTRACT FROM AUTHOR]

Social‐ecological systems like fisheries provide food, livelihoods and recreation. However, lack of data and its integration into governance hinders their conservation and management. Stakeholders possess site‐specific knowledge crucial for confronting these challenges. There is increasing recognition that Indigenous and local knowledge (ILK) is valuable, but structural differences between ILK and quantitative archetypes have stalled the assimilation of ILK into fisheries management, despite acknowledged bias and uncertainty in scientific methods. Conducting a systematic review of fisheries‐associated ILK research (n = 397 articles), we examined how ILK is accessed, applied, distributed across space and species, and has evolved. We show that ILK has generated qualitative, semi‐quantitative and quantitative information for diverse taxa across 98 countries. Fisheries‐associated ILK research mostly targets small‐scale and artisanal fishers (70% of studies) and typically uses semi‐structured interviews (60%). We revealed large variability in sample size (n = 4–7638), predicted by the approach employed and the data generated (i.e. qualitative studies target smaller groups). Using thematic categorisation, we show that scientists are still exploring techniques, or 'validating' ILK through comparisons with quantitative scientific data (20%), and recording qualitative information of what fishers understand (40%). A few researchers are applying quantitative social science methods to derive trends in abundance, catch and effort. Such approaches facilitate recognition of local insight in fisheries management but fall short of accepting ILK as a valid complementary way of knowing about fisheries systems. This synthesis reveals that development and increased opportunities are needed to bridge ILK and quantitative scientific data. [ABSTRACT FROM AUTHOR]

Mangrove forest is an ecosystem‐based solution for disaster risk reduction in the Philippines, but its historical deforestation has hampered its capacity to protect coastal communities. With the increasing occurrence of storm surge in the Philippines, mangrove reforestation projects have received renewed attention, but many have failed. Community participation was deemed to be essential in those projects that did well. Hence, this paper examines successful mangrove restoration and rehabilitation projects in the Philippines to find out how community participation contributed to the accomplishments. The study found that while the transfer of science‐based ecological knowledge from project managers to the community is an important factor in ensuring successful initial planning and implementation, its integration into existing local ecological knowledge—'localisation' of science‐based ecological knowledge or hybrid ecological knowledge formation—helped to facilitate long‐term community‐based mangrove management beyond project duration by empowering community members and enabling project acceptance and ownership. Still, continuous local institutional support is a necessary anchor for community resilience. [ABSTRACT FROM AUTHOR]

Scientists increasingly draw on fishers' ecological knowledge (FEK) to gain a better understanding of fish biology and ecology, and inform options for fisheries management. We report on a study of FEK among fishers along the Lower Ucayali River in Peru, a region of exceptional productivity and diversity, which is also a major supplier of fish to the largest city in the Peruvian Amazon. Given a lack of available scientific information on stock status, we sought to identify temporal changes in the composition and size of exploited species by interviewing fishers from 18 communities who vary in years of fishing experience since the mid‐1950s. We develop four FEK‐based indicators to assess changes in the fish assemblage and compare findings with landings data. We find an intensification of fishing gear deployed over time and spatiotemporal shifts in the fish assemblage and reported declines in species weight, which point to a fishing‐down process with declines across multiple species. This finding is reflected in a shifting baseline among our participants, whereby younger generations of fishers have different expectations regarding the distribution and size of species. Our study points to the importance of spillover effects from the nearby Pacaya‐Samira National Reserve and community initiatives to support the regional fishery. Reference to fishers' knowledge also suggests that species decline is likely underreported in aggregated landings data. Despite the dynamism and diversity of Amazonian floodplain fisheries, simple FEK‐based indicators can provide useful information for understanding fishing‐induced changes in the fish assemblage. Fishers hold valuable knowledge for fishery management and conservation initiatives in the region. [ABSTRACT FROM AUTHOR]

Local ecological knowledge (LEK) is a community-based conservation effort that promotes sustainable management of natural resources. However, studies on LEK are very limited in the Philippines. To address this information gap, LEK on land snails in Mount Banahaw, Luzon Island, Philippines was investigated. Key informant interviews and focus group discussions were conducted in the four communities (Dolores, Lucban, Tayabas and Majayjay) along the slope of the mountain. A snail calendar was used as a tool for identifying the hunting season and practices of these communities on land snails. The results showed that the communities were knowledgeable on macro land snails (>5 mm shell size) such as the introduced species, Lissachatina fulica and the endemic and edible, Ryssota otaheitana, but were unaware of micro land snails (<5 mm shell size). Locals also demonstrated an awareness of the snails' ecosystem functions as a food source for other animals and agents of nutrient cycling. Additionally, sustainable hunting of R. otaheitana in communities was observed. Only adult R. otaheitana were harvested, leaving the juveniles to grow and reproduce. In Lucban, the people hunted while they were waiting for the harvest season of their crops. In Tayabas, the community observed that the snail was abundant during wet and moist soil conditions when leaf litter, its primary food, decomposed easily. In Majayjay, hunting was associated with the blooming of the flowering plant, Erythrina variegata. In Dolores, hunting was practiced after clearing farmland. This research underscores the importance of determining LEK in developing policies and regulations on sustainable utilization and conservation of land snails in a tropical forest setting.

We present the first photographic records of the tiger shark (Galeocerdo cuvier) at the remote Rapa Nui (Easter Island) in the south‐east Pacific. Previous anecdotal sightings exist for tiger sharks in this region; however these records have not been reported within the scientific domain. The present sighting occurred in a period of unusually warm sea surface temperature, which has been shown to influence tiger shark range extensions elsewhere. Novel and historic species occurrence records are valuable for determining and predicting species' environmental tolerances, migratory routes, and distributional limits. [ABSTRACT FROM AUTHOR]

Understanding the drivers of conflict and coexistence in human–wildlife relations are critical to conservation. This study sought to understand th varying attitudes of local indigenous people towards wildlife, focusing on the Titicaca Grebe (Rollandia microptera), an endangered endemic species found in Lake Titicaca and surrounding waters in the Altiplano of Peru and Bolivia. We used an ethnobiology approach to understand which demographic, sociocultural, and economic factors influenced (a) attitudes and local ecological knowledge (LEK) towards the grebe and (2) their effects on Indigenous–wildlife conflict or coexistence. We used a qualitative, semi-structured questionnaire to interview 221 individuals over six months in villages surrounding Lake Titicaca. Participants primarily consisted of locals from the Aymara, Quechan, and Uro Indigenous groups. We found that most individuals expressed apathy towards the grebe, with a significant minority being hostile towards it. Hostility was concentrated amongst fishers and was driven by economic concerns. Knowledge of the grebe was low in the general population, but higher amongst fishers. There was, however, widespread willingness to conserve the grebe amongst the general population, particularly when informed that the grebe is endemic to the Altiplano. This small environmental education intervention suggested increased positive attitudes and a willingness to conserve the grebe. Non-homogenous perspectives towards the grebe were held within and between indigenous groups, suggesting the need for future research into intra-indigenous group dynamics in indigenous–wildlife relations. Future conservation work on the Titicaca Grebe should focus on reducing grebe-fisher conflict, both real and perceived, and on educating people on the grebe's endemic status. [ABSTRACT FROM AUTHOR]

Small‐scale fisheries ensure food security and employment in Angolan coastal communities. These dynamic, widespread fisheries remain mostly unregulated, with limited data available despite their likely significant impact on marine megafauna. We used an interview‐based survey to investigate local fisher interactions with elasmobranchs (sharks and rays) and gather information on utilization, trade and perceptions. All fishers (n = 83) landed elasmobranchs. Most fishers considered sharks as bycatch (74.7%, n = 62), while 100% targeted rays (Order Myliobatiformes), and 62.8% (n = 52) targeted guitarfishes (Order Rhinopristiformes). Over 80% of fishers reported declining catches and sizes of elasmobranchs over the last 30 years, raising concerns about the sustainability of these fisheries. Utilization and trade routes varied depending on elasmobranch products, with exports to China (fins) and local market sales (meat). Specifically, 8.4% (n = 5) of fishers confirmed meat and fin exports to China (4.8%, n = 3). The protection of sharks was considered by 32.5% (n = 30) of respondents, while 21.7% (n = 18) believed only certain shark species should be protected. Most respondents reported that rays (80.5%, n = 67) and guitarfishes (61%, n = 51) should not be protected. Regarding the ban on fishing, none considered it for ray species, with only 6.1% (n = 5) supporting this idea for guitarfishes. We highlight the lack of elasmobranch‐specific conservation measures and the need for a multi‐pronged approach to inform policy. Considering the scale of these fisheries, management actions need to be urgently developed and implemented to ensure the sustainability of elasmobranch fisheries while securing the livelihoods of coastal communities.

The global food production system is increasingly strained by abrupt and unpredictable weather events, which hinder communities' ability to adapt to climate variations. Despite advances in meteorological predictions, many communities lack the academic knowledge or infrastructure to interpret these complex models. This gap highlights the need for solutions that make climate forecasts more accessible and actionable, especially for communities reliant on natural resources. This study explores the potential of enhancing seasonal climate forecasts by integrating local ecological knowledge (LEK) with scientific data. Specifically, we combined ethnobiological information gathered between 2022 and 2024 with existing oceanographic and ecological data to create an ethnobiological calendar for four fishing cooperatives. An ethnographic approach was used to understand the population's ethnobiological knowledge and their perceptions of marine heatwaves and climate change impacts. Coastal monitoring data was collected using moorings that recorded temperature over a 14-year period (2010–2024). To characterize giant kelp dynamics, we used an existing dataset of multispectral Landsat images, which estimates the surface canopy biomass of giant kelp forests. Ecological monitoring was conducted annually every summer from 2006 to 2023 to record the in situ abundance of ecologically and economically important invertebrate and fish species. Combining oceanographic, ecological, and ethnographic data, allowed for alligning fishers' observations with recorded marine heatwave events and ecological shifts. Our findings revealed that these observations closely matched documented marine heatwave data and corresponding ecological changes. The integration of LEK with scientific oceanographic data can significantly improved our understanding of dynamic climate regimes, offering contextually relevant information that enhances the reliability and utility of seasonal climate forecasts. By incorporating yearly data into an ethnobiological calendar, we promote more inclusive, community-based approaches to environmental management, advocating for the integration of LEK in climate adaptation efforts, emphasizing its crucial role in strengthening resilience strategies against climatic shocks.

Abstract Local ecological knowledge (LEK), tied to specific cultures, is crucial for sustainability in conservation initiatives. Therefore, including holders of this knowledge in management decisions is essential. Collecting protected area‐specific data on local people's attitudes, opinions and perceptions towards wildlife, especially for highly threatened species like great apes, is therefore crucial for effective conservation. This study emphasizes the importance of LEK as an interdisciplinary approach, highlighting its essential role in informing conservation decisions and understanding human–environment interactions. To fill the information gap on the LEK on the Nigeria‐Cameroon chimpanzee in central Cameroon, we used questionnaires to assess the LEK of respondents specifically their perceptions, opinions and attitudes towards the population trend of chimpanzees, as well as their opinion about the current management systems of Mpem and Djim National Park. We collect data from 240 respondents in 15 villages in the neighbourhood of the park. Using generalized linear mixed models, we were also able to assess socioeconomic and demographic factors that correlate with the opinions, attitudes and perceptions of the respondents towards chimpanzee conservation. About 87% of the respondents exhibited good knowledge about chimpanzees and 59% reported taboos related to chimpanzees. About 94% were aware of laws that prohibit the hunting of chimpanzees, while 87% agreed that it is a good initiative to conserve chimpanzees, and 42% reported that their population increased. Almost half (52%) of the respondents said they were satisfied with the current park management system. Age, gender, education level, number of children in the household and time spent in the community were predictors that influenced the attitude, opinion and perception of the respondents while occupation and the geographic distance between the village and the park did not. Our findings suggest that raising awareness of human–chimpanzee coexistence through adult education programmes should target specific demographic groups, such as those with larger families, limited education, older age, individuals with lower LEK or native. These findings brought insights to guide future studies and should be taken into account when discussing regional management.

Interactions between people and large carnivores on shared landscapes can have harmful social and ecological consequences. Human–carnivore coexistence depends on an assemblage of sociological factors including effective management institutions that address the social costs of carnivore conservation and promote tolerance toward wildlife. In East Africa, large carnivores are particularly troublesome for herders who depend on livestock for subsistence and wellbeing. This paper provides an overview of human–hyena conflict in the Tarangire ecosystem of northern Tanzania. It presents descriptive results from a questionnaire survey (n = 1076) administered as part of an anthropological study (2019–2020; 2022; 2023) of human–wildlife interactions across twelve villages inhabited by Maasai agropastoralists. The survey instrument was designed through community-based participatory research methods to convey herder concerns about the impacts of spotted hyenas (Crocuta crocuta) on the livestock economy. Based on the perceptions and local ecological knowledge of Maasai interlocutors, the paper provides an overview of the spatial and temporal patterns of human–hyena interactions. Perceived frequencies of hyena attacks on kraaled livestock were unevenly distributed geographically, with those homesteads surrounding Manyara Ranch most heavily affected. Based on herder-reported livestock losses, the costs of depredation by spotted hyenas across the study area were estimated at approximately USD 904.84 per household per year. Most homesteads lacked fortified bomas and would benefit from the provision of lights and fencing materials to improve kraal structures. The paper’s central finding is that spotted hyenas represent a pressing, everyday concern for local pastoralists. Unsurprisingly, herders despise hyenas and are intolerant of sharing landscapes with them. For carnivore conservation outside protected areas to thrive in Tanzania, conservationists and policy makers must engage more meaningfully with the lived experiences of local herders who bear the brunt of conservation costs on their livelihoods.

In this article we analyze participatory approaches used in three research studies where local ecological knowledge (LEK) and Earth system models (ESMs) were combined to deepen our understanding of human-environment systems and produce usable data tools for decision making. In all three cases, the combination of these complimentary types of knowledge produced richer data about the environmental conditions being studied. In the first, participants used LEK to identify ways that an ESM-produced fire simulation differs from usual seasonal patterns. In the second, participants used LEK to adapt and apply regional climate projections to the specifics of local microclimates. And in the third, participants’ ecological knowledge identified important local ecosystem processes that were not currently represented in ESMs, including the distinct roles of various vegetation in local hydrology, as well as fuel loading conditions for predicting wildfire intensity. Although all three cases demonstrate how combining LEK and ESM data improves collaborative understandings of human-environment processes, we also found that key differences in the participatory approaches we used, particularly as regards timing and type of participation from local communities, produced three different sets of outcomes. Specifically, as our cases move from less (first case) to more (third case) participation and knowledge integration, the outcomes move beyond combining ESM and LEK knowledge and toward changing the design and configuration of ESMs themselves with insights from LEK. However, we simultaneously find that these deeper levels of integration require multiyear relationships between researchers and communities, agreements on data sovereignty for communities, and community’s involvement in designing and instigating the project, which are not necessary to achieve lower levels of integration. In all three cases, we found that communities are willing to participate in this work when relationships of trust have been built, data privacy and sovereignty is agreed upon and carefully protected, and epistemic differences are respected.

In planning and monitoring measures to protect wildlife in an area, it is important to have a reliable baseline estimate of population size and trends. There has been minimal published information on a small population of elephants, a keystone and endangered species, in a large area west of Etosha National Park in Namibia, known locally as the Northern Highlands. It is a highly remote, mountainous area in which it is difficult to count elephants. It is semi-desert, where the protection of wildlife is at increasing risk from climate change events, and research on the elephant population is a priority. We interviewed 34 community game guards in the Northern Highlands, focusing on the number of elephants and distinguishing features in known groups. Based on the collated knowledge, and analysis to reduce double counting of known groups, we estimate that there are between 78 and 212 elephants in the Northern Highlands, with a best estimate of 128. The wide range is an indication of the current uncertainties in the method. However, we conclude that this low-cost method, if adapted based on lessons from this pilot study, would be applicable for longer-term ecological monitoring in areas that have a low population density.

Throughout human history, calendars have been a universal constant in all societies, providing a sense of continuity and connection with the environment. Their importance lies in their crucial role in social organization, decision-making in the management of biological resources, and survival. Despite their vitality in these areas, there is a theoretical and methodological gap in the reconstruction and detailed understanding of local calendars in ethnobiological studies. In this article, we present a methodological approach to address this gap, supported by empirical data from our research. The primary purpose of this methodology is to preserve local ecological knowledge and promote food sovereignty, as well as sustainable and ecologically responsible use of biotic resources. This methodology is applicable in both aquatic and terrestrial environments, providing a comprehensive tool for understanding and preserving the complex interactions between human societies and their surroundings. Our goal is to provide the audience with a clear and replicable methodology for recording ethnobiological calendars. This methodology is part of a larger project that, at the request of some fishing cooperatives in the Mexican Northwest Pacific, seeks to promote adaptation and resilience to climate, social, market, and political change in coastal communities worldwide. The calendar is a key component in building a scalable model for participatory knowledge co-production and its application in marine and coastal management and adaptation. [ABSTRACT FROM AUTHOR]

Mount Hermon, Lebanon, has a long history of human occupation reflected in the landscape and ecology that makes biocultural perspectives highly relevant for the conservation of this mountain territory. We conducted semi-structured interviews with 126 local informants during 2022–2023 using a Values, Rules and Knowledge (VRK) framework. Our findings illustrate that while instrumental values of this territory (e.g., water sources, tourism, land, and good soils for crop production) were most frequently cited by informants (50.84%), relational values (e.g., social identity, sense of place, and spirituality in human-nature relationships) also scored high (41.88%), with subjective intrinsic values of nature as an end in itself (e.g., the right of nature to exist on its own behalf) least cited (7.28%). At the same time, co-occurrence of formal rules (62.26% of informants' citations) and informal rules (37.74%) among actors with significant local ecological knowledge (LEK) in resource use, was identified in a 70.27% of the cases. Principal component analysis demonstrated five strong correlations of enabling or conflicting interactions within the VRK framework that merit close consideration for a meaningful participatory conservation strategy of both biodiversity and cultural diversity in a key hotspot. Our findings contribute to a better understanding of the socioecological context of the Mt. Hermon ecosystem and to orient decision making for effective management and conservation planning in the region and beyond. [ABSTRACT FROM AUTHOR]

In drylands, where resources are scarce, wild edible plant (WEP) knowledge is crucial to overcome food scarcity. Understanding the distribution pattern of local ecological knowledge (LEK) about WEP and identifying knowledge holders are key steps to assessing the resilience and vulnerability of knowledge systems. However, little is known about how WEP knowledge is distributed across life stages and gender of people living in arid regions. Here, we study the distribution of WEP knowledge within a small-scale society from southwestern Madagascar, a region known for its dry climate and related food crises. We worked with Tanalana male and female children and adults using semi-structured interviews and free listings. Tanalana people display a sophisticated LEK adapted to the extreme environment in which they live, with a distinct distribution pattern regarding theoretical and practical knowledge across life stages and gender. While women and men cited similar WEP, children and adults cited different sets of WEP, suggesting they hold differentiated bodies of theoretical knowledge, however our results suggest similarity in practical knowledge across life-stage and gender. We argue that resource limitation and food scarcity might be so pervasive in the area that extensive sharing of knowledge on WEP could be an adaptation to the extremely dry environment.
