Gordon Ulmer, Sydney Silverstein, and I just published a short article (with lots of photos!) in the latest edition of Anthropology Today. It examines how projected environmental changes in the Amazonian city of Iquitos have been used by the Peruvian government to propose the resettlement of a low-income community and promote state-led redevelopment plans. The article is available free of charge over the next month. You can download it here.
Yesterday I published a new research article titled “How Religion, Race, and the Weedy Agency of Plants Shape Rural Amazonian Home Gardens” in the latest edition of Culture, Agriculture, Food and Environment. You can read a pre-press version of it on my academia.edu page. Here is the abstract:
“Across Brazilian Amazonia, it is common to find rural households that keep plants with magico-medicinal properties in their home gardens. Despite widespread occurrence of such plants, some Amazonians—especially in Evangelical communities—openly criticize their use as incongruent with Christian belief and practice. In this article, I offer ethnographic observations that indicate divergent attitudes toward magico-medicinal plants between Evangelical Christians and Amazonian folk Catholics, the latter of whom borrow heavily from Afro-Brazilian and indigenous religions. I contend that Evangelicals’ attempts to establish distance from such plants is due in part to histories of ethnic and racial marginalization that are indexed in their use. Still, many magico-medicinal plants are weedy species that actively colonize areas occupied by humans, thus openly defying Evangelical attempts to evade them. In this manner, magico-medicinal plants are not just subject to human agencies, but are arguably agents in their own right.”
I just completed revisions on an article titled “What Happens When We Flush?” that will appear in the September edition of Anthropology Now. You can read a pre-print version of it on my Academia.edu site. The article discusses how the modern flush toilet has perpetuated the illusion that human waste can be made to “disappear.” Examining the industrial origins of the flush toilet, I point out some of its problematic consequences as a model of sanitation in the contemporary world. Using examples from Pre-Columbian Amazonia and 19th century East Asia, I highlight alternative models of managing human excreta that have proven benefits for agricultural production, which might serve to reorient human relations to excrement in industrialized societies today.
I just published an article titled Trail Trees: Living Artifacts (Vivifacts) of Eastern North America with my colleagues Brad Painter and Cailín Murray. It’s featured in the open access journal Ethnobiology Letters and it’s freely available to all.
My latest research article was just published online with the journal Human Ecology. Here is the abstract:
Smallholder farmers play a critical role in the maintenance of global agrobiodiversity. However, the social and environmental factors that shape agrobiodiversity and its management in rural smallholder communities are still debated among scholars. This study examines variation in the diversity of useful plant species (i.e., species richness) managed by households located in three distinct environments along the Lower Madeira River in the Central Brazilian Amazon: Amazonian Dark Earths (ADE), upland Oxisols (OX), and floodplain soils (FP). Among the 106 households studied, those located on ADE managed a significantly higher number of useful species than those on floodplain soils but not than those on Oxisols. A generalized linear mixed effects model indicates that the age of the household head, number of household members and adults, and area of land under cultivation are statistically significant factors that influence species richness across all households. Ethnographic data are employed to contextualize these findings and discuss other influences on agrobiodiversity management in rural Amazonian communities, including regional historical ecology and the life histories of individual farmers.
My latest research article (co-authored with Chris McCarty and Charles Clement) is to be published in the December 2013 issue of Current Anthropology. It’s already available ahead of print through JSTOR. This is the abstract:
Social exchange networks play a critical role in the maintenance and distribution of crop diversity in smallholder farming communities throughout the world. The structure of such networks, however, can both support and constrain crop diversity and its distribution. This report examines varietal distribution of the staple crop manioc among rural households in three neighboring caboclo communities in Brazilian Amazonia. The results show that the centrality of households in exchange networks had no significant correlation with the number of manioc varieties maintained by households. However, household centrality did show a significant correlation with households’ perceived knowledge of manioc cultivation as well as the total area of manioc they cultivated. Although households with the most knowledgeable and active producers played a central role in the distribution of planting materials and manioc varieties, they did not maintain higher varietal diversity than more peripheral households in this study. This case study represents an important example of how social networks can constrain varietal distribution and contribute to low crop diversity in agricultural communities.
My most recent research article on the contribution of “magic” plants to Amazonian agrobiodiversity has just been published in the fall issue of the journal Human Organization. You can access the article here.
