Global analysis of social learning’s archetypes in natural resource management
Although social learning (SL) conceptualization and implementation are flourishing in sustainability sciences, and its non-rigid conceptual fluidity is regarded as an advantage, research must advance the understanding of SL phenomenon patterns based on empirical data, thus contributing to the identification of its forms and triggering mechanisms, particularly those that can address urgent Anthropocene socio-ecological problems. This study aims to…

The Role of Ethnobotanical Skills and Agricultural Labor in Forest Clearance
The Uneven Reach of Decentralization
Decentralization reforms aim at strengthening democracy by promoting political participation among citizens. Research shows (1) that information is a prerequisite for political participation and (2) that people face different private costs in acquiring information. Here we combine the two lines of research and ask: what private costs hamper the acquisition of information on decentralization? For the analysis, we use data from an indigenous popula…
Individual Wealth Rank, Community Wealth Inequality, and Self-Reported Adult Poor Health
Growing evidence suggests that economic inequality in a community harms the health of a person. Using panel data from a small-scale, preindustrial rural society, we test whether individual wealth rank and village wealth inequality affects self-reported poor health in a foraging-farming native Amazonian society. A person's wealth rank was negatively but weakly associated with self-reported morbidity. Each step up/year in the village wealth hierarc…

Non-market Returns to Traditional Human Capital
In industrial economies schooling produces positive non-market returns but do traditional forms of human capital also produce such returns, and do schooling and traditional human capital act as complements or substitutes in their association with well-being? Drawing on data from 450 adults (16+ years of age) from an indigenous Amazonian society in Bolivia, we estimate the association between traditional plant knowledge and nutritional status as m…
Developmental changes in the relationship between leptin and adiposity among Tsimané children and adolescents
Leptin is thought to signal energy stores, thus helping the body balance energy intake and expenditure. However, the strong relationship between leptin and adiposity in populations with adequate nutrition or common obesity is not universal across ecologic contexts, and leptin often correlates only weakly, or not at all, with adiposity in populations of lean or marginally‐nourished males. To clarify whether the relationship between adiposity and l…
Cash Cropping, Farm Technologies, and Deforestation
Research suggests that cash cropping is positively associated with deforestation. We use three-year data (2000-2002, inclusive) from 493 households to estimate the association between cash cropping rice and deforestation. Doubling the area sown with rice is associated with a 26-30 percent increase in the area of forest cleared during the next cropping season. We simulate the changes in rice cultivation to reach a daily income level of $1/person f…
Ethnobotanical Knowledge and Crop Diversity in Swidden Fields
Signaling by consumption in a native Amazonian society☆
Concepts and Methods in Studies Measuring Individual Ethnobotanical Knowledge
We review 34 quantitative studies that have measured individual-level variations in ethnobotanical knowledge, analyzing how those studies have conceptualized and operationalized ethnobotanical knowledge. We found that this type of research is recent but growing, and is concentrated in indigenous peoples of developing countries. We also found that studies differ on how they conceptualize and measure individual ethnobotanical knowledge. As it is th…
Schooling's contribution to social capital
Understanding why traditional cultures weaken matters because they embody humanity's heritage. Schooling has been singled out as an abrader of traditional culture. We assess whether schooling erodes one aspect of traditional culture: social capital as shown by generosity to people outside the household. In industrial nations researchers find positive associations between social capital and schooling. We hypothesize that in pre‐industrial societie…
Ethnobotanical Skills and Clearance of Tropical Rain Forest for Agriculture
Indigenous peoples are often considered potential allies in the conservation of biological diversity. Here we assess whether ethnobotanical skills of indigenous people contribute to a reduction in the clearance of tropical rain forest. We measured ethnobotanical skills of male household heads and area of rain forest cleared for agriculture among 128 households of Tsimane', a native Amazonian group in Bolivia. We used multivariate regressions to e…

Evaluating indices of traditional ecological knowledge
BACKGROUND: New quantitative methods to collect and analyze data have produced novel findings in ethnobiology. A common application of quantitative methods in ethnobiology is to assess the traditional ecological knowledge of individuals. Few studies have addressed reliability of indices of traditional ecological knowledge constructed with different quantitative methods. METHODS: We assessed the associations among eight indices of traditional ecol…

The Effect of Market Economies on the Well-Being of Indigenous Peoples and on Their Use of Renewable Natural Resources
Assessing the effects of markets on the well-being of indigenous peoples and their conservation of natural resources matters to identify public policies to improve well-being and enhance conservation and to test hypotheses about sociocultural change. We review studies about how market economies affect the subsistence, health, nutritional status, social capital, and traditional ecological knowledge of indigenous peoples and their use of renewable …

Knowledge and Consumption of Wild Plants
Researchers have often equated ethnobotanical knowledge collected through interview questions with actual uses of plants, but knowledge and uses of plants might or might not move in lockstep. Using data from 132 adults living in two villages of a foraging-farming society in the Bolivian Amazon, the Tsimane ́, we compare ethnobotanical knowledge with uses of wild and semi-domesticated plants. Villages differed in proximity to the market town and i…
Physical growth and nutritional status of Tsimane' Amerindian children of lowland Bolivia
This study examines patterns of growth and nutritional status of indigenous Tsimane' children under 9 years of age (n = 199 boys and 210 girls), based on a cross‐sectional sample from 58 villages from the Beni Deparment of lowland Bolivia. Compared with US children, Tsimane' children are quite short, with linear growth tracking at or below the US 5th centile in both sexes. The prevalence of low height‐for‐age (“stunting;” HA Z‐scores ≤−2) is 52% …

Predictors of C‐reactive protein in Tsimane' 2 to 15 year‐olds in lowland Bolivia
Infectious disease is a major global determinant of child morbidity and mortality, and energetic investment in immune defenses (even in the absence of overt disease) is an important life‐history variable, with implications for human growth and development. This study uses a biomarker of immune activation (C‐reactive protein) to investigate an important aspect of child health among the Tsimane', a relatively isolated Amerindian population in lowla…

Why Do Subsistence-Level People Join the Market Economy? Testing Hypotheses of Push and Pull Determinants in Bolivian Amazonia
Why would subsistence-level indigenous people join the market economy? The question matters because, in answering it, one contributes to a venerable debate about the effects of markets on well-being. Anthropologists have generally treated market participation as exogenous. Market participation is in fact endogenous if it reflects choice. We review hypotheses of determinants that push or pull people to the market, including resource scarcity from …

Validity of Self-Reports to Measure Deforestation
To assess rates of deforestation, researchers typically use questionnaires. But do questionnaires provide accurate information about the extent of forest clearance by households? In this article, the authors provide data on the amount of deforestation in a Tsimane' Amerindian village (Bolivia) and assess informant error by cross-checking three different assessments: (1) a direct physical measure by a research team of each plot cleared from the fo…

Patience in a Foraging-Horticultural Society
Patience, or the ability to delay gratification, matters in the behavioral and medical sciences and in public policy because it correlates with a wide range of desirable outcomes. For instance, patience correlates positively with income, wealth, conservation of natural resources, health, and savings and negatively with crime and drug addiction. Anthropologists have made few contributions to cross-cultural studies of patience despite its importanc…

Personal and Group Incentives to Invest in Prosocial Behavior
Ethnographic evidence, empirical research, and results of experimental studies suggest that people across cultures invest in prosocial behavior, but little research addresses the relative importance of personal versus group incentives to invest in prosocial behavior. We estimate the relative weight of personal and group incentives for households to invest in prosocial behavior using two waves of panel data (2001 and 2002) from ca. 350 Tsimane' Am…
