The new edited volume Thinking with Soils – edited by Juan Francisco Salazar, Céline Granjou, Matthew Kearnes, Anna Krzywoszynska, and Manuel Tironi – is now available. You can download a pre-print version of my chapter here, which examines the use of biosolids (i.e. treated sanitation waste) as part of a broader trend to “close the loop” in contemporary agricultural management. The chapter is part of a larger ethnographic research project in which I’m bringing together insights from wastewater treatment experts, soil scientists, and farmers to understand both the productive possibilities and potential pitfalls of using treated sanitation waste on agricultural landscapes in the US (and beyond).
Our zine “Infrastructural Digest” is now completed(!) and 250 copies have just been printed for the opening of the Privy2 demonstration garden. The zine features original artwork and essays by OSU students and faculty that reflect on the history of sanitation and its relationship to agriculture. You can download a copy here.
Our latest article is out, which examines the history and cross-cultural management of human waste (or “night soil”) as an agricultural resource. The paper grew out of a collaborative class project that I proposed to Master’s degree students enrolled in my Environmental Anthropology course in the spring of 2017. Together, we delved into the archaeology and history of night soil use and management, as well as some recent ethnographic research on the subject. This paper synthesizes that work and puts it in conversation with contemporary theorizing of the “metabolic rift” — or the notion that the rise of industrial capitalism led to a fundamental rupture in human relations to the earth’s ecological systems. The article, titled “Night Soil: Origins, Discontinuities, and Opportunities for Bridging the Metabolic Rift,” can be found in the latest issue of the open access journal Ethnobiology Letters.
A tractor spreads biosolids (i.e. treated sanitation sludge) over a field in central Washington state.
If you want to learn about all the fascinating things central Ohio does with its so-called “human waste,” come to this public talk I’ll be giving at Whetstone Library in Columbus on October 27th at 1pm. I’ll discuss how the city is transforming waste into an agricultural resource used to sustain poplar farms on abandoned strip mines, fertilize commodity crops, and produce garden compost, among other things. To conclude, I’ll discuss some of the ongoing obstacles and concerns about expansion of its use in the region. See you there!
Cymene Howe and Dominic Boyer invited me on to the Cultures of Energy podcast to discuss my recent book Amazonia in the Anthropocene. Our conversation touched on an number of different topics including Amazonian deforestation, the politics of indigeneity, terra preta do índio (Amazonian Dark Earth), American Confederates in the Amazon, weeds (and weed), flooding in south Florida, Marx and the metabolic rift, and “night soil” (i.e. human shit). The episode just went online today. Give it a listen.
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.
