Cultural Change and Traditional Ecological Knowledge: An Empirical Analysis from the Tsimane' in the Bolivian Amazon

Abstract

Among the different factors associated to change in traditional ecological knowledge, the study of the relations between cultural change and traditional ecological knowledge has received scan and inadequate scholarly attention. Using data from indigenous peoples of an Amazonian society facing increasing exposure to the mainstream Bolivian society, we analyzed the relation between traditional ecological knowledge, proxied with individual plant use knowledge (n=484), and cultural change, proxied with individual-and village-level (n=47) measures of attachment to traditional beliefs and values. We found that both the individual level of detachment to traditional values and the village level of agreement in detachment to traditional values were associated with individual levels of plant use knowledge, irrespective of other proxy measures for cultural change. Because both the individual-and the village-level variables bear statistically significant associations with plant use knowledge, our results suggest that both the individual-and the supraindividual level processes of cultural change are related to the erosion of plant use knowledge. Results from our work highlight the importance of analyzing processes that happen at intermediary social units -the village in our case study-to explain changes in traditional ecological knowledge.

“…Second, there are other risks associated with independent production, including the erosion of community governance and the Amazonian culture of collective action. These issues are outside the scope of this paper, but certainly merit attention from policy makers and scholars (Perreault, 2005;Gurven et al, 2015;Reyes-García et al, 2016).…”

Income and Wellbeing in a Society on the Verge to Market Integration: The Case of the Tsimane’ in the Bolivian Amazon

“…The Tsimane’ society has traditionally done so through success in subsistence activities, strong social relations, and its cosmologic belief system. These pathways are increasingly endangered by market integration, Christian proselytism, the extraction of natural resources, and the confrontation with modern Bolivian society (Reyes-García et al 2014b). We speculate that this process leads to a confusion of worldview, values and beliefs among the Tsimane’, which manifests itself in a sort of emotional numbing which in turn results in sinking overall emotions.…”

Wetlands need people: a framework for understanding and promoting Australian indigenous wetland management

“…The transition of indigenous groups away from customary ways of life to mainstream lifestyles (such as living in towns and participation in formal systems of education and economy) has altered engagement in cultural education systems (Strang 1997, Reyes-García et al 2014. For example, research with indigenous peoples of South America found that formal schooling (Reyes-García et al 2010), lowered dependence on traditional resources, and exposure to new technology (Paniagua-Zambrana et al 2016) were associated with the loss of some types of cultural knowledge among younger generations.…”
