Medicinal plants provide indigenous and peasant communities worldwide with means to meet their healthcare needs. Homegardens often act as medicine cabinets, providing easily accessible medicinal ...plants for household needs. Social structure and social exchanges have been proposed as factors influencing the species diversity that people maintain in their homegardens. Here, we assess the association between the exchange of medicinal knowledge and plant material and medicinal plant richness in homegardens. Using Tsimane’ Amazonian homegardens as a case study, we explore whether social organization shapes exchanges of medicinal plant knowledge and medicinal plant material. We also use network centrality measures to evaluate people’s location and performance in medicinal plant knowledge and plant material exchange networks. Our results suggest that social organization, specifically kinship and gender relations, influences medicinal plant exchange patterns significantly. Homegardens total and medicinal plant species richness are related to gardeners’ centrality in the networks, whereby people with greater centrality maintain greater plant richness. Thus, together with agroecological conditions, social relations among gardeners and the culturally specific social structure seem to be important determinants of plant richness in homegardens. Understanding which factors pattern general species diversity in tropical homegardens, and medicinal plant diversity in particular, can help policy makers, health providers, and local communities to understand better how to promote and preserve medicinal plants in situ. Biocultural approaches that are also gender sensitive offer a culturally appropriate means to reduce the global and local loss of both biological and cultural diversity.
Research on natural resource management suggests that local perceptions form the basis upon which many small-scale societies monitor availability and change in the stock of common-pool natural ...resources. In contrast, this literature debates whether local perceptions can be effective in guiding the sustainable management of natural resources. With empirical evidence on this matter still highly limited, we explored the role of local perceptions as drivers of harvesting and management behavior in a small-scale society in Bolivian Amazonia. We conducted structured interviews to capture local perceptions of availability and change in the stock of thatch palm (Geonoma deversa) among the Tsimane’, an indigenous society of foragers-horticulturalists (n = 296 adults in 13 villages). We analyzed whether perceptions of availability match estimates of abundance obtained from ecological data and whether differences in perception help to explain harvesting behavior and local management of thatch palm. Perceptions of availability ofG. deversaare highly contingent upon the social, economic, and cultural conditions within which the Tsimane’ have experienced changes in the availability of the resource, thus giving a better reflection of the historical, rather than of the ecological, dimensions of the changes undergone. Although local perceptions might fall short in precision when scrutinized from an ecological standpoint, their importance in informing sustainable management should not be underestimated. Our findings show that most of the harvesting and management actions that the Tsimane’ undertake are, at least partially, shaped by their local perceptions. This paper contributes to the broader literature on natural resource management by providing empirical evidence of the critical role of local perceptions in promoting collective responses for the sustainable management of natural resources.
Biodiversity of European cultural landscapes is threatened by land abandonment and intensification. While the conservation benefits of traditional management practices have been long acknowledged, ...recognition of traditional knowledge started only recently in Europe. Respect for the holders of traditional knowledge (TK holders) themselves lags even more behind, often leading to social injustices. Social injustices towards TK holders span from disrespect and misrepresentation, invisibility, misunderstanding, economic and political vulnerability, unethical collaborations, rights violations, disconnection, uncontextualized education to lack of inclusivity – leading to neglect of TK holders in conservation science, policy and practice. Resolving these social injustices would benefit both people and nature. Benefits of resolving injustices include better cooperation in conservation management, mutual understanding, improved representation and participation, increased respect, economic and legal security, strengthened land stewardship, better tradition-based conservation innovations, and more appropriate management regulations. Best practices are presented to inspire ways to foster recognition for TK holders and their knowledge, worldviews and values, promote the inclusion of plurality of values and voices in the media and school curricula, encourage meaningful participatory decision making, mobilise strategies to re-design and decolonize financial support mechanisms, decrease bureaucratic loads, and promote TK holder-led conservation activities. Supporting TK holders and keeping traditional land management practices alive should be considered as a social justice imperative of great strategic importance for long-term social-ecological resilience in Europe.
•European cultural landscapes are threatened by the erosion of traditional knowledge.•Traditional knowledge holders face social injustices harmful also for conservation.•Social injustices include disrespect, misrepresentation, and perverse regulations.•Meaningful collaborations, heard voices and fair partnerships can resolve injustice.•Resolving social injustices would benefit both people and nature in Europe.

Biocultural approaches are gaining attention for coping with current sustainability challenges. These approaches recognize that biological and cultural diversity are inextricably linked. Indigenous ...and local knowledge (ILK) plays an important role in biocultural approaches as these often build on local cultural perspectives. This review explores how ILK is conceptualized and applied in the scientific literature published in Spanish on biocultural approaches to sustainability and examines the status and trends of ILK described in this literature. For this, we reviewed 72 publications and conducted a category-based qualitative content analysis. We found multiple conceptualizations of ILK, although most of them shared some commonalities, such as the close link to specific biocultural contexts. The results suggests that there are three themes that seem to be both relevant and controversial within the reviewed literature: the different strategies to bridging diverse knowledge systems, the conflictive views on the role of ILK in sustainability, and the threats to ILK. We also show that future research would benefit from greater attention to power relations and context-specific dynamics in bridging diverse knowledge systems, as there is still room to improve approaches and tools to promote the co-production of knowledge while supporting and enhancing the self-determination of IPLC. We conclude that the way biocultural approaches to sustainability engage with ILK can support shape a variety of alternative futures, which may differ from currently dominant perspectives on sustainability, and further demonstrate that the design and implementation of conservation policies that protect both people and nature can be enhanced.
Capacity building has been identified as being of importance for the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). As the IPBES is becoming an influential ...expert organization, it is essential to examine what capacity building means in its context, what capacities it has built, and what implications these capacities have. This study explores these issues by focusing on the IPBES's general strategy for capacity building, the IPBES's fellowship programme and to what extent there are additional capacity building needs that can be addressed. The study shows that the IPBES has focused its capacity building efforts on the science side of the science-policy interface while, thus far, it has neglected to build capacities on the policy side of the interface. The study provides insight into how capacity building for the science-policy interface sets preconditions for science-policy relations at different levels and scales within biodiversity and ecosystem services and beyond.

The diets of contemporary hunter-gatherers are diverse and highly nutritious, but are rapidly changing as these societies integrate into the market economy. Here, we analyse empirical data on the ...dietary patterns and sources of foods of three contemporary hunter-gatherer societies: the Baka of Cameroon (
n
= 160), the Tsimane’ of Bolivia (
n
= 124) and the Punan Tubu of Indonesia (
n
= 109). We focus on differences among villages with different levels of integration into the market economy and explore potential pathways through which two key elements of the food environment (food availability and food accessibility) might alter the diets of contemporary hunter-gatherers. Results suggest that people living in isolated villages have more diverse diets than those living in villages closer to markets. Our results also suggest that availability of nutritionally important foods (i.e., fruits, vegetables and animal foods) decreases with increasing market integration, while availability of fats and sweets increases. The differences found seem to relate to changes in the wider food environment (e.g., village level access to wild and/or market foods and seasonality), rather than to individual-level factors (e.g., time allocation or individual income), probably because food sharing reduces the impact of individual level differences in food consumption. These results highlight the need to better understand the impact of changes in the wider food environment on dietary choice, and the role of the food environment in driving dietary transitions.

Objective
To assess the burden of hypoglycemia in patients with diabetes mellitus (DM) in Spain, including epidemiological data and information relating to healthcare resource utilization (HRU) and ...costs, and patients’ quality of life (QoL).
Methods
A systematic literature review (SLR) was conducted to identify studies that included original information on epidemiology, HRU and costs, and/or QoL associated with hypoglycemia in patients with DM in Spain, published in either Spanish or English, between January 2007 and April 2017.
Results
Fifteen articles, involving 14 studies, were identified in the SLR and included in the analysis. The estimated rate of severe hypoglycemia (SH) events per patient per year ranged from 0.90 to 1.50 in patients with type 1 DM (T1DM) and from 0.30 to 0.63 in patients with type 2 DM (T2DM). The data on HRU differed extensively between studies, making it difficult to draw a conclusion. Total costs per SH event ranged from €409.97 in patients with T1DM to €713.10 in patients with DM. Work absence was reported in 11.80–18% of the working patients. Further, patients who experienced hypoglycemic events expressed a higher fear and had a poorer QoL than those who did not report these events.
Conclusion
Although the data included in the SLR were difficult to synthesize due to heterogeneity of the study designs and patient characteristics in the 14 studies, our search identified a high burden associated with hypoglycemic events in terms of HRU and costs, and patients’ QoL. Further research is recommended to reach a consensus on hypoglycemia definition and study design to provide robust evidence on the burden of hypoglycemia and to accurately weigh the impact of this acute complication in Spain.

Although subsistence hunting is cross-culturally an activity led and practiced mostly by men, a rich body of literature shows that in many small-scale societies women also engage in hunting in varied ...and often inconspicuous ways. Using data collected among two contemporary forager-horticulturalist societies facing rapid change (the Tsimane’ of Bolivia and the Baka of Cameroon), we compare the technological and social characteristics of hunting trips led by women and men and analyze the specific socioeconomic characteristics that facilitate or constrain women’s engagement in hunting. Results from interviews on daily activities with 121 Tsimane’ (63 women and 58 men) and 159 Baka (83 women and 76 men) show that Tsimane’ and Baka women participate in subsistence hunting, albeit using different techniques and in different social contexts than men. We also found differences in the individual and household socioeconomic profiles of Tsimane’ and Baka women who hunt and those who do not hunt. Moreover, the characteristics that differentiate hunter and non-hunter women vary from one society to the other, suggesting that gender roles in relation to hunting are fluid and likely to change, not only across societies, but also as societies change.

Researchers have analysed whether school and local knowledge complement or substitute each other, but have paid less attention to whether those two learning models use different cognitive strategies. ...In this study, we use data collected among three contemporary hunter-gatherer societies with relatively low levels of exposure to schooling yet with high levels of local ecological knowledge to test the association between i) schooling and ii) local ecological knowledge and verbal working memory. Participants include 94 people (24 Baka, 25 Punan, and 45 Tsimane') from whom we collected information on 1) schooling and school related skills (i.e., literacy and numeracy), 2) local knowledge and skills related to hunting and medicinal plants, and 3) working memory. To assess working memory, we applied a multi-trial free recall using words relevant to each cultural setting. People with and without schooling have similar levels of accurate and inaccurate recall, although they differ in their strategies to organize recall: people with schooling have higher results for serial clustering, suggesting better learning with repetition, whereas people without schooling have higher results for semantic clustering, suggesting they organize recall around semantically meaningful categories. Individual levels of local ecological knowledge are not related to accurate recall or organization recall, arguably due to overall high levels of local ecological knowledge. While schooling seems to favour some organization strategies this might come at the expense of some other organization strategies.

Food Sovereignty (FS) is growing in popularity in food-nature academic discussions. This systematic review depicts 1) the level of engagement and 2) the topics related to the "Works with Nature" ...pillar (WwNP) of food sovereignty present in the academic literature. Most articles engaged with this pillar. Common topics included ecological agriculture practices, rejecting intensive-industrial agriculture and exploring how human-nature values and traditional ecological knowledge are affected. An in-depth engagement with ecological conditions (e.g. biodiversity, ecosystem functions, and resilience) was less prominent. We conclude that a broader variety of topics could be explored to support politically engaged research on the systemic nature of food purported by a paradigm born from grassroots movements.
