Triumph Of The Commons: Sustainable Community Practices On Rapa Nui (Easter Island), Robert J. Dinapoli, Carl P. Lipo, Terry L. Hunt

Anthropology Faculty Scholarship

The history of Rapa Nui (Easter Island) has long been framed as a parable for how societies can fail catastrophically due to the selfish actions of individuals and a failure to wisely manage common-pool resources. While originating in the interpretations made by 18th-century visitors to the island, 20th-century scholars recast this narrative as a “tragedy of the commons,” assuming that past populations were unsustainable and selfishly overexploited the limited resources on the island. This narrative, however, is now at odds with a range of archaeological, ethnohistoric, and environmental evidence. Here, we argue that while Rapa Nui did experience large-scale deforestation …

Deep Learning Reveals Extent Of Archaic Native American Shell-Ring Building Practices, Dylan Davis, Gino Capsari, Carl P. Lipo, Matthew Sanger

Anthropology Faculty Scholarship

In the mid-Holocene (5000 - 3000 cal B.P.), Native American groups constructed shell rings, a type of circular midden, in coastal areas of the American Southeast. These deposits provide important insights into Native American socioeconomic organization but are also quite rare: only about 50 such rings have been documented to date. Recent work using automated LiDAR analysis demonstrates that many more shell rings likely exist than are currently recorded in state archaeological databases. Here, we use deep learning, a form of machine intelligence, to detect shell ring deposits and identify their geographic range in LiDAR data from South Carolina. We …

Approximate Bayesian Computation Of Radiocarbon And Paleoenvironmental Record Shows Population Resilience On Rapa Nui (Easter Island), Robert J. Dinapoli, Enrico Crema, Timothy Reith, Carl P. Lipo, Terry L. Hunt

Anthropology Faculty Scholarship

Examining how past human populations responded to environmental and climatic changes is a central focus of the historical sciences. The use of summed probability distributions (SPD) of radiocarbon dates as a proxy for estimating relative population sizes provides a widely applicable method in this research area. Paleodemographic reconstructions and modeling with SPDs, however, are stymied by a lack of accepted methods for model fitting, tools for assessing the demographic impact of environmental or climatic variables, and a means for formal multi-model comparison. These deficiencies severely limit our ability to reliably resolve crucial questions of past human-environment interactions. We propose a …

Population Structure Drives Cultural Diversity In Finite Populations: A Hypothesis For Localized Community Patterns On Rapa Nui (Easter Island, Chile), Carl P. Lipo, Robert J. Dinapoli, Mark E. Madsen, Terry L. Hunt

Anthropology Faculty Scholarship

Understanding how and why cultural diversity changes in human populations remains a central topic of debate in cultural evolutionary studies. Due to the effects of drift, small and isolated populations face evolutionary challenges in the retention of richness and diversity of cultural information. Such variation, however, can have significant fitness consequences, particularly when environmental conditions change unpredictably, such that knowledge about past environments may be key to long-term persistence. Factors that can shape the outcomes of drift within a population include the semantics of the traits as well as spatially structured social networks. Here, we use cultural transmission simulations to …

The Role Of Culture In Sustainable Communities: The Case Of Rapa Nui (Easter Island, Chile), Pamela A. Mischen, Carl P. Lipo

Anthropology Faculty Scholarship

We explore how the combination of cultural heritage and present-day cultural affili- ations influences the construction of the concept of sustainability at the scale of the community using the case study of Rapa Nui (Easter Island, Chile). We argue that overlapping affiliations—expressed through administrative culture, organizational culture, and professional culture—influence the views held by governance leaders. Furthermore, the role of cultural heritage must be considered in efforts to change and perpetuate sustainability-related behaviors within a community. Using archeo- logical and historical evidence from the pre-contact and historical record of Rapa Nui, we discuss how cultural heritage evolved endogenously in response …

A Model-Based Approach To The Tempo Of “Collapse”: The Case Of Rapa Nui (Easter Island), Robert J. Dinapoli, Timothy M. Reith, Carl P. Lipo, Terry L. Hunt

Anthropology Faculty Scholarship

Rapa Nui (Easter Island, Chile) presents a quintessential case where the tempo of investment in monumentality is central to debates regarding societal collapse, with the common narrative positing that statue platform (ahu) construction ceased sometime around AD 1600 following an ecological, cultural, and demographic catastrophe. This narrative remains especially popular in fields outside archaeology that treat collapse as historical fact and use Rapa Nui as a model for collapse more generally. Resolving the tempo of “collapse” events, however, is often fraught with ambiguity given a lack of formal modeling, uncritical use of radiocarbon estimates, and inattention to information embedded in …

The Integration Of Lidar And Legacy Datasets Provides Improved Explanations For The Spatial Patterning Of Shell Rings In The American Southeast, Dylan S. Davis, Robert Dinapoli, Matthew Sanger, Carl P. Lipo

Anthropology Faculty Scholarship

Archaeologists have struggled to combine remotely sensed datasets with preexisting information for landscape-level analyses. In the

American Southeast, for example, analyses of lidar data using automated feature extraction algorithms have led to the identification of over

40 potential new pre-European-contact Native American shell ring deposits in Beaufort County, South Carolina. Such datasets are vital for understanding settlement distributions, yet a comprehensive assessment requires remotely sensed and previously surveyed archaeological data. Here, we use legacy data and airborne lidar-derived information to conduct a series of point pattern analyses using spatial models that we designed to assess the factors that best explain …

The Ethnohistory Of Freshwater Use On Rapa Nui (Easter Island, Chile), Sean W. Hixon, Robert J. Dinapoli, Carl P. Lipo, Terry L. Hunt

Anthropology Faculty Scholarship

Sources of drinking water on islands often present critical constraints to human habitation. On Rapa Nui (Easter Island, Chile), there is remarkably little surface fresh water due to the nature of the island’s volcanic geology. While several lakes exist in volcanic craters, most rainwater quickly passes into the subsurface and emerges at coastal springs. Nevertheless, the island sustained a relatively large human population for hundreds of years, one that built an impressive array of monumental platforms (ahu) and statues (moai). To understand how Rapanui acquired their scarce fresh water, we review ethnohistoric data from first European arrival (1722) through the …

Foundation For Measuring Community Sustainability, Pamela A. Mischen, George C. Homsy, Carl P. Lipo, Robert Holahan, Valerie Imbruce, Andreas Pape, Joe Graney, Ziang Zhang, Louisa M. Holmes, Manuel Reina

Anthropology Faculty Scholarship

In order to understand the impact of individual communities on global sustainability, we need a community sustainability assessment system (CSAS). While many sustainability assessment systems exist, they prove inadequate to the task. This article presents the results of a systematic review of the literature on existing sustainability assessment systems; offers a definition of a sustainable community; provides a multi-scale, systems approach to thinking about community; and makes recommendations from the field of performance measurement for the construction of a CSAS.

Rapa Nui (Easter Island) Monument (Ahu) Locations Explained By Freshwater Sources, Robert J. Dinapoli, Carl P. Lipo, Tanya Brosnan, Terry L. Hunt, Sean W. Hixon, Alex E. Morrison, Matthew Becker

Anthropology Faculty Scholarship

Explaining the processes underlying the emergence of monument construction is a major theme in contemporary anthropological archaeology, and recent studies have employed spatially-explicit modeling to explain these patterns. Rapa Nui (Easter Island, Chile) is famous for its elaborate ritual architecture, particularly numerous monumental platforms (ahu) and statuary (moai). To date, however, we lack explicit modeling to explain spatial and temporal aspects of monument construction. Here, we use spatially-explicit point-process modeling to explore the potential relations between ahu construction locations and subsis- tence resources, namely, rock mulch agricultural gardens, marine resources, and freshwa- ter sources—the three most critical resources on Rapa …

Diet Of The Prehistoric Population Of Rapa Nui (Easter Island, Chile) Shows Environmental Adaptation And Resilience, Catrine L. Jarmine, Thomas Larsen, Terry L. Hunt, Carl P. Lipo, Reidar Solsvik, Natalie Wallsgrove, Cassie Ka'apu-Lyons, Hilary G. Close, Brian N. Popp

Anthropology Faculty Scholarship

Objectives: The Rapa Nui “ecocide” narrative questions whether the prehistoric population caused an avoidable ecological disaster through rapid deforestation and over-exploitation of natural resources. The objective of this study was to characterize prehistoric human diets to shed light on human adaptability and land use in an island environment with limited resources.

Materials and methods: Materials for this study included human, faunal, and botanical remains from the archaeological sites Anakena and Ahu Tepeu on Rapa Nui, dating from c. 1400 AD to the historic period, and modern reference material. We used bulk carbon and nitrogen isotope analy- ses and amino acid …

Using Structure From Motion Mapping To Record And Analyze Details Of The Colossal Hats (Pukao) Of Monumental Statues On Rapa Nui (Easter Island), Sean W. Hixon, Carl P. Lipo, Terry L. Hunt, Christopher Lee

Anthropology Faculty Scholarship

Structure from motion (SfM) mapping is a photogrammetric technique that offers a cost-effective means of creating three-dimensional (3-D) visual representations from overlapping digital photographs. The technique is now used more frequently to document the archaeological record. We demonstrate the utility of SfM by studying red scoria bodies known as pukao from Rapa Nui (Easter Island, Chile). We created 3-D images of 50 pukao that once adorned the massive statues (moai) of Rapa Nui and compare them to 13 additional pukao located in Puna Pau, the island’s red scoria pukao quarry. Through SfM, we demonstrate that the majority of these bodies …

Scaling Up The Self, Scaling Down The World: Self-Objectification And The Politics Of Carbon Offsets And Personalised Genomics, Joshua Reno

Anthropology Faculty Scholarship

Two global initiatives, the Genographic Project and the Carbon Lottery, share an ambition to make abstract, global processes—human evolution and climate change—comprehensible and engaging to non-specialists. Despite their differences, they both do so by means of self-objectifications that scale up the selves of participants and scale down complex, spatio-temporal models of human-world relations. Based on the author’s auto-ethnographic experience as a participant in both initiatives, it is argued that carbon calculators and personalised genomics involves a pragmatics of scale that evaluates and compares users on the basis of their relative expression of, or deviation from, a standard. Furthermore, this is …

Measuring Cultural Relatedness Using Multiple Seriation Ordering Algorithms, Mark E. Madsen, Carl P. Lipo

Anthropology Faculty Scholarship

Seriation is a long-standing archaeological method for relative dating that has proven effective in probing regional-scale patterns of inheritance, social networks , and cultural contact in their full spatiotemporal context. The orderings produced by seriation are produced by the continuity of class distributions and uni-modality of class frequencies, properties that are related to social learning and transmission models studied by evolutionary archaeologists. Linking seriation to social learning and transmission enables one to consider ordering principles beyond the classic unimodal curve. Unimodality is a highly visible property that can be used to probe and measure the relationships between assemblages, and it …

Waste And Waste Management, Joshua Reno

Anthropology Faculty Scholarship

Discard studies have demonstrated that waste is more than just a symptom of an all-too-human demand for meaning or a merely technical problem for sanitary engineers and public health officials. The afterlife of waste materials and processes of waste management reveal the centrality of transient and discarded things for questions of materiality and ontology and marginal and polluting labor and environmental justice movements, as well as for critiques of the exploitation and deferred promises of modernity and imperial formations. There is yet more waste will tell us, especially as more studies continue to document the many ways that our wastes …

Arqueología Crítica Y Praxis [Critical Archaeology And Praxis], Randall H. Mcguire

Anthropology Faculty Scholarship

La Arqueología se ha utilizado tradicionalmente para apoyar al poder en las arenas de lucha por la economía, las ideologías, las identidades y la política. La arqueología puede ser una forma de praxis para ayudar a crear un mundo más humano, una vez que los arqueólogos se convierten en más que “simples oradores”. La gran mayoría de los arqueólogos practica su arte para obtener el conocimiento del mundo. Varios arqueólogos han tratado de criticar al mundo y el lugar de la arqueología en el mismo. Muy pocos han entrado completamente en la dialéctica de la praxis y han construido una …

Book Review Of 'Evolutionary And Interpretive Archaeologies' Edited By Ethan E. Cochrane And Andrew Gardner, Liane Gabora, Carl P. Lipo

Anthropology Faculty Scholarship

Evolutionary and Interpretive Archaeologies, edited by Ethan E. Cochrane and
Andrew Gardner, grew out of a seminar at the Institute for Archaeology at
University College London in 2007. It consists of 15 chapters by archaeologists
who self-identify themselves as practitioners who emphasize the benefits of
evolutionary or interpretive approaches to the study of the archaeological
record. While the authors' theoretical views are dichotomous, the editors' aim
for the book as a whole is not to expound on the differences between these two
kinds of archaeology but to bring forward a richer understanding of the
discipline and to highlight areas of …

Continuity And The Open Whole: A Comparison Of Recent (Peircian) Ethnographies, Joshua Reno

Anthropology Faculty Scholarship

A comparison of Eduardo Kohn's "How forests think: Toward an anthropology beyond the human" and David Pedersen's "American value: Migrants, money, and meaning in El Salvador and the United States" which explores their relationship to the continuist ontology of the philosopher Charles S. Peirce and its implications for contemporary anthropology.

Combinatorial Structure Of The Deterministic Seriation Method With Multiple Subset Solutions, Mark E. Madsen, Carl P. Lipo

Anthropology Faculty Scholarship

Seriation methods order a set of descriptions given some criterion (e.g., unimodality or minimum distance between similarity scores). Seriation is thus inherently a problem of finding the optimal solution among a set of permutations of objects. In this short technical note, we review the combinatorial structure of the classical seriation problem, which seeks a single solution out of a set of objects. We then extend those results to the iterative frequency seriation approach introduced by Lipo et al. (1997), which finds optimal subsets of objects which each satisfy the unimodality criterion within each subset. The number of possible solutions across …

Toward A New Theory Of Waste: From "Matter Out Of Place" To Signs Of Life , Joshua Reno

Anthropology Faculty Scholarship

This paper offers a counterpoint to the prevailing account of waste in the human sciences. This account identifies waste, firstly, as the anomalous product of arbitrary social categorizations, or ‘matter out of place’, and, secondly, as a distinctly human way of leaving behind and interpreting traces, or a mirror of culture. Together, these positions reflect a more or less constructivist and anthropocentric approach. Most commonly, waste is placed within a framework that privileges considerations of meaning over materiality and the threat of death over the perpetuity of life processes. For an alternative I turn to bio-semiotics and cross-species scholarship around …

From Biopower To Energopolitics In England's Modern Waste Technology, Joshua Reno, Catherine Alexander

Anthropology Faculty Scholarship

Two energy-generating technologies in Britain which transform waste into a resource are compared. One is the (in)famous Combined Heat and Power incinerator in Sheffield, the other a forgotten biological digester in Devon utilizing anaerobic microbes. Both sites are early exemplars of experimental and biopolitical waste disposal technologies—incineration and anaerobic digestion—now regarded as leading alternatives for reducing the United Kingdom’s dependence on landfill and fossil fuel; both sites also inspired public resistance at critical moments in their development. The analysis here relates how activists and technicians struggle to demonstrate competing truths about alternative energy. Through comparison, it becomes clear that, beyond …

The Human Transformation Of Rapa Nui (Easter Island, Pacific Ocean), Terry L. Hunt, Carl P. Lipo

Anthropology Faculty Scholarship

Rapa Nui (Easter Island) has become widely known as a case study of human-induced environmental catastrophe resulting in cultural collapse. The island's alleged "ecocide" is offered as a cautionary tale of our own environmental recklessness. The actual archaeological and historical record for the island reveals that while biodiversity loss unfolded, the ancient Polynesians persisted and succeeded. Demographic "collapse" came with epidemics of Old World diseases introduced by European visitors. In this paper, we outline the process of prehistoric landscape transformation that took place on Rapa Nui. This process includes the role of humans using fire to remove forest and convert …

Technically Speaking: On Equipping And Evaluating “Unnatural” Language Learners , Joshua Reno

Anthropology Faculty Scholarship

This article compares different communicative trials for apes in captivity and children with autism in order to investigate how ideological assumptions about linguistic agency and impairment are constructed and challenged in practice. To the extent that Euro-American techniques of “unnatural” language instruction developed during the Cold War era have been successful, it is because communicative interactions are broken down into basic components, and would-be language learners are equipped with materials, devices, and habits that make up for their distinct bio/social deficits. Such linguistic equipment can present a challenge to the ideological presumption of a subject inherently gifted with the rudiments …

Managing The Experience Of Evidence England’S Experimental Waste Technologies And Their Immodest Witnesses, Joshua Reno

Anthropology Faculty Scholarship

This article explores the technoenvironmental politics associated with government-sponsored climate change mitigation. It focuses on England’s New Technologies Demonstrator Programme, established to test the “viability” of “green” waste treatments by awarding state aid to eight experimental projects that promise to divert municipal waste from landfill and greenhouse gases from the atmosphere. The article examines how these demonstrator sites are arranged and represented to produce noncontroversial and publicly accessible forms of evidence and experience and, ultimately, to inform environmental policy and planning decisions throughout the country. As in experimental science, this process requires that some bear witness to the demonstrators, but …

Beyond Risk: Emplacement And The Production Of Environmental Evidence , Joshua Reno

Anthropology Faculty Scholarship

I offer a counterpoint to the prevailing risk literature that focuses not on (mis)perceptions of danger but on the production and circulation of different forms of evidence and the environmental claims they promote. Rather than reproduce the epistemic dichotomies associated with risk discourse, I discuss attempts by waste-industry technicians, government inspectors, lawyers, area residents, and activists to generate persuasive accounts of a large, U.S. landfill and its porous boundaries. I argue that the differential influence of their various claims is best understood by examining what it means to know and care for a place.

Motivated Markets: Instruments And Ideologies Of Clean Energy In The United Kingdom , Joshua Reno

Anthropology Faculty Scholarship

This article examines efforts to reconcile capitalist and ecological values, focusing in particular on the instruments and ideologies that pervade the United Kingdom's developing renewable energy sector. In keeping with neoliberal models of economic knowledge and practice, renewable energy instruments target the motivations of individuals by using incentive programs to reach environmental policy goals. The argument focuses especially on the way newly implemented market devices shape and represent the motivations of energy producers, suppliers, and traders. The centerpiece of the U.K. government's initiative is the creation of an artificial market in renewability, bought and sold as a virtual commodity. Although …

Your Trash Is Someone's Treasure: The Politics Of Value At A Michigan Landfill , Joshua Reno

Anthropology Faculty Scholarship

This article discusses scavenging and dumping as alternative approaches to deriving value from rubbish at a large Michigan landfill. Both practices are attuned to the indeterminacy and power of abandoned things, but in different ways. Whereas scavenging relies on acquiring familiarity with an object by getting to know its particular qualities, landfilling and other forms of mass disposal make discards fungible and manipulable by stripping them of their former identities. By way of examining the different ways in which people become invested in the politics of value at the landfill, whether as part of expressions of gender and class or …
