What makes social-ecological systems (SESs) robust? In this paper, we look at the institutional configurations that affect the interactions among resources, resource users, public infrastructure providers, and public infrastructures. We propose a framework that helps identify potential vulnerabilities of SESs to disturbances. All the links between components of this framework can fail and thereby reduce the robustness of the system. We posit that the link between resource users and public infrastructure providers is a key variable affecting the robustness of SESs that has frequently been ignored in the past. We illustrate the problems caused by a disruption in this link. We then briefly describe the design principles originally developed for robust common-pool resource institutions, because they appear to be a good starting point for the development of design principles for more general SESs and do include the link between resource users and public infrastructure providers.

A Framework to Analyze the Robustness of Social-ecological Systems from an Institutional Perspective

This review calls for the definition of a landscape approach in archaeology. After tracing the development of the landscape idea over its history in the social sciences and examining the compatibility between this concept and traditional archaeological practice, we suggest that archaeology is particularly well suited among the social sciences for defining and applying a landscape approach. If archaeologists are to use the landscape paradigm as a “pattern which connects” human behavior with particular places and times, however, we need a common terminology and methodology to build a construct paradigm. We suggest that settlement ecology, ritual landscapes, and ethnic landscapes will contribute toward the definition of such a broadly encompassing paradigm that also will facilitate dialogue between archaeologists and traditional communities.

An Archaeology of Landscapes: Perspectives and Directions

By sequencing 523 ancient humans, we show that the primary source of ancestry in modern South Asians is a prehistoric genetic gradient between people related to early hunter-gatherers of Iran and Southeast Asia. After the Indus Valley Civilization's decline, its people mixed with individuals in the southeast to form one of the two main ancestral populations of South Asia, whose direct descendants live in southern India. Simultaneously, they mixed with descendants of Steppe pastoralists who, starting around 4000 years ago, spread via Central Asia to form the other main ancestral population. The Steppe ancestry in South Asia has the same profile as that in Bronze Age Eastern Europe, tracking a movement of people that affected both regions and that likely spread the distinctive features shared between Indo-Iranian and Balto-Slavic languages.

The Formation of Human Populations in South and Central Asia

Eating and Healing is aimed at exploring the idea that food can heal. The underlying argument of the volume is that, around the world, indigenous and rural people do not separate food and medicine, but rather consider them in a continuum. From the use in Spain of herbal teas as digestive beverages, to the antioxidant properties of Tibetan foods, we learn that the continuum concept is not unique to a single culture, but a common way in which humans use the natural environment. The various chapters of the volume describe a range of wild and semi-domesticated foods that traditionally have been used both as food and medicine. Although most chapters focus on the use of wild and semi-domesticated plants, the consumption of other foods (i.e., fish, mushrooms, seaweed) suggests that the overlapping nature of food and medicine is not particular to the plant kingdom, but a common way of conceptualizing. The publication of this volume is timely. The book appears at a moment in which the use of food as medicine is gaining attention among the general public in Western society. The volume, however, presents a refreshing perspective of the link between food intake and health. While medical doctors recommend the intake of dietary supplements and food scientists work to develop new “miraculous” foods (such as the golden rice) containing the nutrients lacking in many diets, this book is a call to go back to the essentials, to look at the local resources around us, and to consider the cultural context interwoven with the consumption of foods and medicines. As a whole, however, the volume does not present an overly optimistic and simplistic approach. Throughout the book, different authors point at three potential caveats of generalizing the ingestion of traditional foods as medicines. First, plants that are highly nutritious also have the potential to be highly toxic, so it is not possible to generalize their consumption without further inspection. Second, the eating of traditional foods and medicines is culturally prescribed and their intake disregarding the cultural system associated to them can result in a loss of effectiveness. Last, promoting the consumption of wild foods as medicines can increase the demand of those foods with potential pernicious effects on their sustainable use because of overextraction. By addressing the interface between food, medicine, and culture, Eating and Healing fills an important gap in ethnobiological research. The volume, however, would have benefited from including more quantitative contributions testing the various hypotheses presented. For example, quantitative data should allow researchers to test whether, in fact, people maintaining traditional diets enjoy better health. Future studies on the topic would benefit from using quantitative methods to test the relations between food and medicine.

Cultural transmission, copying errors, and the generation of variation in material culture and the archaeological record

The late pre-Hispanic period in the US Southwest (A.D. 1200–1450) was characterized by large-scale demographic changes, including long-distance migration and population aggregation. To reconstruct how these processes reshaped social networks, we compiled a comprehensive artifact database from major sites dating to this interval in the western Southwest. We combine social network analysis with geographic information systems approaches to reconstruct network dynamics over 250 y. We show how social networks were transformed across the region at previously undocumented spatial, temporal, and social scales. Using well-dated decorated ceramics, we track changes in network topology at 50-y intervals to show a dramatic shift in network density and settlement centrality from the northern to the southern Southwest after A.D. 1300. Both obsidian sourcing and ceramic data demonstrate that long-distance network relationships also shifted from north to south after migration. Surprisingly, social distance does not always correlate with spatial distance because of the presence of network relationships spanning long geographic distances. Our research shows how a large network in the southern Southwest grew and then collapsed, whereas networks became more fragmented in the northern Southwest but persisted. The study also illustrates how formal social network analysis may be applied to large-scale databases of material culture to illustrate multigenerational changes in network structure.

Transformation of social networks in the late pre-Hispanic US Southwest

The application of method and theory from network science to archaeology has dramatically increased over the last decade. In this article, we document this growth over time, discuss several of the important concepts that are used in the application of network approaches to archaeology, and introduce the other articles in this special issue on networks in archaeology. We argue that the suitability and contribution of network science techniques within particular archaeological research contexts can be usefully explored by scrutinizing the past phenomena under study, how these are abstracted into concepts, and how these in turn are represented as network data. For this reason, each of the articles in this special issue is discussed in terms of the phenomena that they seek to address, the abstraction in terms of concepts that they use to study connectivity, and the representations of network data that they employ in their analyses. The approaches currently being used are diverse and interdisciplinary, which we think are evidence of a healthy exploratory stage in the application of network science in archaeology. To facilitate further innovation, application, and collaboration, we also provide a glossary of terms that are currently being used in network science and especially those in the applications to archaeological case studies.

Networks in Archaeology: Phenomena, Abstraction, Representation

Memory making is a social practice that links people and things together across time and space and ultimately has material consequences.The intersection of matter and social practice becomes archaeologically visible through the deposits created during social activities. Memories are made, not just experienced, and their material traces allow us to understand the materiality of these practices. Indeed, materiality is not just material culture repackaged. Instead, it is about the interaction of humans and materials within a set of cultural relationships. In this book the authors focus on a set of case studies that illustrate how social memories were made through repeated, patterned, and engaged social practices. "Memory work" also refers to the interpretive activities scholars perform when studying social memory. The contributors to this volume share a common goal to map out the different ways in which to study social memories in past societies programmatically and tangibly.

Memory work : archaeologies of material practices

The role of social valuables in establishing and defeating hierarchies in prestate societies is explored through the use of Annette Weiner's concept of “inalienable possessions.” Inalienable possessions are objects made to be kept (not exchanged), have symbolic and economic power that cannot be transferred, and are often used to authenticate the ritual authority of corporate groups. Ethnographic examples from Zuni are used to understand the range of individually and collectively owned inalienable objects in Pueblo societies. I then use three classes of these objects from archaeological contexts to gain insight into the history of collective prestige structures in the Southwest. I argue that inalienable goods are more useful than shape prestige goods for understanding the role of social valuables in many nonstate societies, especially those in which inequalities are based on ritual knowledge.

The Establishment and Defeat of Hierarchy: Inalienable Possessions and the History of Collective Prestige Structures in the Pueblo Southwest

Ceramic bowls from the Greater Southwest are used to show how changes in the exterior decoration of serving vessels are associated with the proxemics of ritual performances. Across the northern Southwest the first use of exterior designs and polychrome ceramics is during the Pueblo III period, which corresponds to a shift in settlement aggregation and the use of open plaza spaces. With the transition to the more enclosed plazas of the Early Pueblo IV period, smaller and less visible exterior designs were used. The trend reversed itself with the use of larger plazas at later Pueblo IV period sites, where serving bowls with greater visual impact were used. Panregional trends are bolstered by a case study from the Mogollon Rim region of Arizona to show how changes in the visual performance characteristics of bowls are associated with the spatial and social proxemics of suprahousehold feasting rituals. I use several characteristics of serving bowls including their size, slip colors, paint and slip contrasts, and the size of exterior designs. These are related to the size and diversity of performance spaces, including plazas, and to other evidence for changes in feasting practices, such as roasting features and faunal remains. I conclude that the changes seen in serving vessels are important for looking at shifts in the scale, visibility, and diversity of public gatherings within Ancestral Pueblo social and ritual trajectories.
