In the forests of Jambi Province, Indonesia, the Indigenous Suku Anak Dalam have encountered rapid alterations to the environment upon which they previously depended. Their culinary traditions—and the knowledge that accompanies them—are placed at a greater risk as palm oil plantations expand and forest areas diminish. This research is based on extensive interviews with customary leaders (called Tumenggung, who guide communal life and cultural practices), elders, and women in five settlements in Merangin District. Rather than regarding participants as research subjects, we engaged with their narratives. The image that emerged was not merely one of food scarcity but also one of cultural loss. Instead of forest tubers, untamed fruits, or fish, families now depend on instant noodles or cassava. The rivers are no longer clean, and the trees that were once a source of both sustenance and medicine are largely extinct. Nevertheless, individuals devise strategies to adapt, including cultivating small crops in the vicinity of their dwellings, collecting what is left along the plantation’s perimeter, and distributing their meager possessions to their neighbors. This research demonstrates that food security for Indigenous peoples is not solely dependent on agriculture or nutrition. It is about the right to have a voice in one’s own land, dignity, and memory. Genuine solutions must transcend technical fixes and nutritional aid. The first step is to respect Indigenous voices, protect their territories, and support their methods of knowing and living before they are also lost. Full article

This article examines William James’s philosophy of science through his pragmatic response to epistemic fallibilism, emphasizing how actionability rather than evidential certainty underwrites both scientific and religious practices. While James explicitly drew comparisons between science and Abrahamic scriptures, my account highlights resonances with non-Western traditions, particularly Indigenous American and Asian epistemologies, also situating some of James’s philosophical motivations within his biography. James may have indirectly absorbed Asian religious and philosophical teachings from American Transcendentalists who engaged with them, and he may have encountered Amerindian perspectives through the cultural milieu of the United States or during his Amazonian expedition. In either case, threads within these global Indigenous traditions align with the weight that James’s work gives to contextual, agent-relative forms of knowing that are inseparable from action. I conclude by discussing how James’s ideas support an account of animism that integrates Amerindian thought with the extended mind thesis. I also detail how his pluralistic account of experience and reality creates conceptual space for the co-existence of science and spirituality, ironically by undermining the assumption that the two operate according to radically distinct epistemologies. Throughout the article, I connect James’s thought to more recent debates in religion and metaphysics. Full article

Background: Exposure to indoor air pollution (IAP), including particulate matter of size 2.5 µm/m³ (PM_2.5) and carbon monoxide (CO) resulting from the combustion of biomass fuels in homes, is an important risk factor associated with growth and developmental delays in neonates. We investigated the association between exposure to HAP and adverse birth outcomes in a birth cohort study of 594 pregnant females in Sri Lanka. Methods: Pregnant females between the ages of 18 and 40 years were enrolled in their first trimester and followed until delivery. Baseline assessments of fuel used for cooking were used to categorize the females into high-exposure (wood and kerosene) or low-exposure (liquid petroleum gas and electricity) groups. Indoor air quality measurements of PM_2.5 (n = 303) and CO (n = 258) were conducted in a subgroup of households. The outcomes at birth included the neonates’ appearance, pulse, grimace, activity, respiration (APGAR) score, Brazelton Neonatal Behavioural Assessment Scale (BNBAS) score, and birth weight. Linear and logistic regressions were used to evaluate the association between household air pollution (HAP) and birth outcomes. Results: Of the 526 neonates assessed at delivery, 55.7% were born to mothers with high HAP exposure and 44.3% with low HAP exposure, respectively. The results of the linear regression found an inverse association between higher exposure to HAP and birthweight in the adjusted and unadjusted models; the birth weight of children in the high-exposure group was lower by 107 g compared to that of the low-exposure group after adjusting for other variables (β = −106.8; 95% confidence intervals: −197.6, −16.0). Exposure status was not associated with birth length, gestational age, or the APGAR score; however, the BNBAS motor score was significantly lower in the neonates of the high-exposure group (6.41 vs. 6.55, p = 0.04), though it was not significant when adjusted for other variables. No correlation was found between the measured indoor PM_2.5 levels and birth weight, birth length, gestational age, APGAR score, or BNBAS score. Conclusions: Exposure to IAP due to emissions from combustion products from biomass fuels adversely affects birth weight. These effects may be more pronounced in vulnerable populations in settings where primary healthcare for pregnant women is limited. Full article

This article presents the results of a participatory urban diagnosis conducted in District 2 of La Paz, Bolivia, as part of an educational cooperation project aimed at exploring the spatial and symbolic dimensions of urban insecurity. Drawing on feminist and intersectional frameworks, this research combined participatory action methods, digital surveys, and collective mapping to identify patterns of fear and exclusion in public space. The analysis revealed significant disparities in how insecurity is perceived and experienced by different social groups—especially women, Indigenous peoples, and LGTBQ+ individuals—highlighting the importance of spatial configuration, social presence, and care infrastructure in shaping everyday urban life. The project also served as a pedagogical innovation, integrating architecture students into a process of civic engagement and co-production of knowledge. The resulting ‘Map of Gender Insecurity’ contributed to local planning efforts through the “Seguras, No Valientes” initiative. While the limited representation of some groups restricts statistical generalization, the approach offers a replicable model for linking research, education, and public action in pursuit of more inclusive and safer cities.

Territorial transformations in Indigenous regions are shaped by intersecting ecological, political, and cultural dynamics. In San Juan Bautista Valle Nacional, Oaxaca, the construction of the Cerro de Oro dam disrupted river flows, displaced livelihoods, and triggered the decline of irrigated agriculture. This study examines the long-term impacts of these changes on land use, demographics, and cultural practices, emphasizing women’s contributions to community resilience. Using a mixed-methods approach, the study integrates geospatial analysis (1992–2021), census data (2000–2020), documentary review, and ethnographic fieldwork, including participatory mapping. Results show a shift toward seasonal rainfed agriculture, fluctuating forest cover, and a rise in female-headed households. Women have emerged as central actors in adapting to change through practices such as seed saving, agroforestry, and backstrap-loom weaving. These spatially grounded practices, enacted across varied socio-ecological zones, sustain food systems, preserve biodiversity, and reinforce biocultural memory. Although often overlooked in formal governance, women’s territorial agency plays a vital role in shaping land use and community adaptation. This research highlights the need to recognize Indigenous women’s roles in managing change and sustaining territorial heritage. Acknowledging these contributions is essential for building inclusive, culturally grounded, and sustainable development pathways in regions facing structural and environmental pressures.

Background: Chinese Red Steppe cattle (CRS) combine indigenous environmental resilience with moderate dairy performance, whereas Holstein cattle (HOL), despite their high milk yield, suffer reduced genetic diversity and compromised adaptation. A comparative analysis of their population genetic architecture and selection signatures can reveal valuable targets for CRS dairy improvement. Methods: We genotyped 61 CRS and 392 HOL individuals using the Illumina GGP Bovine 100K SNP array and performed stringent quality control. Population structure was assessed via principal component analysis, neighbor-joining trees, and sparse nonnegative matrix factorization. Historical effective population size (Ne) and divergence time were inferred with SMC++. Genome-wide selection scans combined Fixation Index (FST) and Cross-Population Composite Likelihood Ratio test (XP-CLR); overlapping high-confidence regions were annotated and subjected to GO and KEGG enrichment analyses. Results: CRS and HOL were clearly separated along PC1 (explaining 57.48% of variance), with CRS exhibiting high internal homogeneity and weak substructure, versus greater diversity and complex substructure in HOL. SMC++ indicated a split approximately 3500 years ago (700 generations) and a pronounced recent decline in Ne for both breeds. Joint selection mapping identified 767 candidate genes; notably, the ACSM1/2B/3/4 cluster on chromosome 25—key to butanoate metabolism—showed the strongest signal. Enrichment analyses highlighted roles for proteasome function, endoplasmic reticulum stress response, ion homeostasis, and RNA processing in regulating milk fat synthesis and protein secretion. Conclusion: This study delineates the genetic divergence and demographic history of CRS and HOL, and pinpoints core genes and pathways—particularly those governing butanoate metabolism and protein quality control—underlying dairy traits. These findings furnish molecular markers and theoretical guidance for precision breeding and sustainable utilization of Chinese Red Steppe cattle. Full article

The giant moray eel (GME; Gymnothorax javanicus) is an important marine species that plays a key ecological role in reef systems and is a valued food source for indigenous communities. However, it is well-known that GMEs pose a food safety risk due to their ability to accumulate high levels of ciguatoxins (CTXs), the toxins known to cause ciguatera poisoning. This study assessed the age, CTX levels, elemental composition, and nutritional profile of seven GME specimens collected from Muri Lagoon, Rarotonga (Cook Islands), representing the most detailed compositional investigation on this species. Age was determined for the three largest specimens, with the oldest being 39 years old. All specimens contained ciguatoxins, with Type I (CTX4A derivatives), Type II (CTX3C derivatives), algal-ciguatoxins, and biotransformed metabolites being detected. There was a higher CTX content in the liver samples compared to flesh samples, with the longest–heaviest specimen containing the highest levels. The CTX1B level observed in flesh samples of all seven eel specimens exceeded the recommended safe guidance level proposed by the USFDA. A similar ciguatoxin profile was observed across flesh sections, with the belly flap or top loin containing the highest levels of CTXs in most specimens. No bioactive metabolites produced by co-occurring harmful microalgae, including regulated shellfish toxins, were detected. Elemental analysis determined the presence of 21 elements, including arsenic, low levels of mercury, and the volcanic elements rubidium and strontium. Nutritionally, the GMEs were shown to be a lean protein source; however, due to the ubiquitous bioaccumulation of CTXs, they pose a food safety risk to consumers. Full article

Before colonization, Indigenous child protection looked like an interdependent community. Indigenous knowledges and relational actions kept all within its fold safe and well. Colonial dispossession of land, degradation of subsistence rights, boarding schools, ongoing child removal, capitalism, and systems of oppression attempted to disconnect Indigenous peoples from their language, lands, ceremonial practices, stories, dances, songs, family, community, and themselves. However, Indigenous communities have held on, persevered, and have begun to turn the tide of intergenerational trauma through the revival of Indigenous wellness and self-determination. We believe local-based Indigenous relational knowledges can end colonial harm and promote wellbeing for all families and children. Our work builds off an Indigenous Connectedness Framework that recognizes the importance of the interrelated wellbeing of a person, family, community, ancestors/future generations, and the Earth. This framework was adapted based on community feedback to better fit the Nome Eskimo Community (NEC) and Bering Strait regional context. This paper shares results of community focus groups that led to the creation of a NEC Piaġiq (wellness) Framework, and shares intentions for pilot implementation of a wellness curriculum and pilot intervention. We will offer insights and lessons learned. We believe self-determined Indigenous wellbeing efforts can lead to improved outcomes for our sacred children and families for generations to come.

Remaining in the place of origin while family, friends, and neighbors emigrate can have adverse effects on psychological well-being. Specific important relationships absent from one’s social network can be especially impactful, while other relationships and network characteristics still available in the home network can be protective against psychological distress. The highlands of western Guatemala experience emigration at high rates and changing social network structures, affecting the mental health of those remaining at home. This study uses socio-centric network data from a single community (N = 653) to investigate the association between having emigrant ties in the United States and experiencing depressive symptoms according to an adapted CESD-20 scale. We also explore which types of relationships and network characteristics increase the likelihood of reporting depressive symptoms or moderate the relationship between emigration and depression. Our results indicate that having emigrant ties and more of them increases the odds of depression, even if only one friend or neighbor emigrated. Those with lower levels of education were also more likely to report depressive symptoms. However, more connected networks offered some protection from depression. Certain critical relationships still available at home, like a mother or sibling, lowered the likelihood of depression. For women, higher transitivity, or network cohesiveness, moderated the relationship between emigration and depression, and for men, a higher proportion of their connections outside of the household than within the household moderated that relationship. These findings may offer some insight into important relationships and network structures that may be leveraged to ease the mental health burden for those remaining at home while friends and loved ones emigrate.

Ancient figures and symbols are carved into a high rock wall beside the Colorado River, just south of where a traditional Native American geotrail crosses the river near Moab, Utah, USA. Based on ethnographic interviews with tribal and pueblo representatives, the rock peckings identify an ancient ceremonial geosite, which, among other purposes, serves as a site for the Celebration of Creation. The interpretation of the site is situated within the geologically complex and ancient cultural heritage region composed of functionally interrelated nested geoscapes that surround the study area. The analysis is informed by ethnographic interviews from six U.S. federally funded studies that involved thirteen participating tribes and pueblos. The analysis is guided by an intellectual framework aligned with internationally recognized UNESCO heritage categories—namely, geosites, geotrails, and geoscapes. Grounded in these UNESCO heritage categories, the analysis advances new interpretive frameworks, theoretical insights, and culturally responsive strategies for heritage management. Full article

In 2020, Bill C92, or an Act Respecting First Nations, Inuit and Metis Children, Youth and Families, came into force in Canada. The Act historically recognized and affirmed Indigenous jurisdiction over child and family services and established national minimal standards for service delivery. In 2024, the Supreme Court of Canada upheld the constitutionality of the Act in an appeal from a Quebec Court of Appeal reference case. The Court stressed all parts of the Act must be viewed as “integrated parts of a unified whole” and required the braiding together of Indigenous laws, state laws and international laws into a “single strong rope.” The Act’s aspirations remain in tension with ongoing challenges in implementation. This article outlines the main provisions of the Act. It then examines the law-making efforts and accomplishments of Indigenous governments exercising jurisdiction using the Act, along with some of the hopes and obstacles encountered through this work. Next, it considers some of the emerging jurisprudence interpreting the Act, and some of the implications this case law has on whether the stated purposes of the Act are being achieved. It concludes by highlighting the ongoing uncertainty and hopes for realizing the full potential and aspirations of the Act. Full article

Microbially induced carbonate precipitation (MICP) refers to the formation of calcium carbonate driven by microbial metabolic processes, such as ureolysis. As an emerging biocementation technique, MICP has garnered attention for various applications in environmental and civil engineering. This study evaluated the feasibility of MICP implementation in a limestone mine. Ureolytic bacteria were isolated from an active limestone quarry at Mt. Buko, Saitama, Japan. Located at an elevation above 1000 m, the site represents a low-temperature environment with an average annual temperature of ~10 °C. The representative isolates, Rhodococcus sp. strains L6 and L8, exhibited tolerance to key environmental factors relevant to MICP applications in the limestone-rich settings, including alkaline pH, high calcium levels, and elevated urea concentrations. Additionally, both strains were psychrotolerant, maintaining growth and urease activity at temperatures as low as 5 °C. Notably, both strains induced calcite crystal formation at 10 °C and 5 °C, although the reaction was slower at 5 °C. Furthermore, strain L6 demonstrated the ability to induce MICP on limestone surfaces, effectively sealing rock fissures. These findings suggest that indigenous microbes retain metabolic activity in the limestone mine and are well suited for MICP applications. Full article

Biodiversity conservation has been identified as an important climate change mitigation tool. Healthy ecosystems act as natural carbon sinks while also strengthening resilience, making them essential for climate change adaptation. Climate change effects have led to various negative impacts, including biodiversity loss and food insecurity. The loss of forest biodiversity threatens vital wild fruits and vegetables that sustain rural communities, disrupting natural food sources and constituting a form of social injustice for poor, vulnerable, and previously marginalised groups in rural and semi-urban communities. Therefore, this study aimed to investigate the relationship between previous biodiversity conservation outcomes, ecosystem services, highly utilised wild vegetables and fruits, food and nutritional security, climate change effects, and climate resilience. We identified gaps in African biodiversity conservation and developed a conceptual framework to highlight integral principles required for the effective biodiversity conservation of wild forests in Africa. The integral principles are active community engagement, a strong network of stakeholders, sustainable plant resources management practices, legal reforms, and the creation of awareness through various platforms. Conservation policies should prioritise African indigenous wild, drought-tolerant vegetables and fruits that serve as an interface between food and medicine; play various roles in human survival in the form of ecosystem services; and act as carbon sinks to ensure a food-secure future with reduced climate change effects. The African indigenous community’s efforts in biodiversity conservation engagements are key to successful outcomes. Full article

We document and analyze an emblematic case study of non-indigenous peasant autonomy and re-peasantization in Sa Kaeo province in the Issan region of Thailand, using a mostly qualitative, single case-study methodology. The Kok Edoi autonomous community, whose members engage in community forest management and increasingly in agroecological farming, was founded more than twenty-five years ago as the product of a land occupation by landless peasants associated with the national Thai social movement, the Assembly of the Poor (AoP), which is part of the global peasant movement, La Via Campesina (LVC). Partially inspired by opportunities given to the community and to AoP by LVC to learn and gain inspiration from Latin American experiences such as the Zapatistas in Mexico, Kok Edoi autonomy exemplifies how the exchange of social movement knowledge and experience can help shape and strengthen local struggles, and it is also suggestive of autonomy as an alternative pathway of resistance and sustainable development in Thailand. We review the literature on territorial autonomy, re-peasantization, and community forestry and autonomy in Thailand and the world. Situating Kok Edoi in Thai history concerning policies and conflicts around land and forests, we examine the type, dimensions, and facets of autonomy and re-peasantization present in Kok Edoi to demonstrate how these factors contribute to the community being considered an emblematic case of peasant autonomy, peasant land occupation, peasant management of and livelihood derived from natural resources, more autonomous alternative markets, collective accumulation, and political training and mobilization that contributes to a class-based national movement. This is novel in an academic literature that has to date focused principally on indigenous autonomy, largely in Latin America. Full article
