Archaeology’s Golden Opportunity
Earth and other natural scientists frequently depict human-caused global environmental change as a recent development, a perspective exemplified by the proposal to formalize a human epoch in the Geologic Time Scale—the Anthropocene—beginning in 1952. Yet the science of archaeology offers abundant evidence of anthropogenic planetary change over thousands of years, from land clearing using fire to early methane emissions from agriculture, preindust…
Comparative Spatial Analysis Reveals Important Structural Similarities Between Ancient Angkor and Late Anglo-Saxon Hampshire
Angkor (800–1435 CE ) is considered the type site for “low-density agrarian urbanism”, a loosely defined archaeological label used to describe settlements with urban traits but dispersed spatial structure. Angkor’s abandonment from the fifteenth century has fueled concerns that low-density cities, now common globally, may be inherently unstable. The spatial distinctiveness of Angkor relative to other premodern rural–urban systems, however, has ne…
Making comparative archaeological and historical urbanism rigorous and open access through the URBank data platform
Adapting to a global urban future requires diverse, long-term perspectives on urbanism. URBank supports this by bringing together global deep-time urban datasets in a modern open-science computing platform. Its design eschews checklist definitions of cities, representing the variability of past urbanism and enabling systematic comparative spatiotemporal research

Black to the Future - The Power of Designing Afrofuturist Technology with Black Women, Femmes, and Non-Binary People
Black women, femmes, and non-binary people (BWFNBP) are historically excluded in tech spaces, resulting in an exclusion of their perspectives in technology innovation. To explore how this group imagines the future of technology, and how they see themselves within it, we conducted a series of speculative design workshops. We asked participants to design a future communication technology and address its benefits, harms, and strategies for mitigatin…

Black Twitter is gold
Community + Culture features practitioner perspectives on designing technologies for and with communities. We highlight compelling projects and provocative points of view that speak to both community technology practice and the interaction design field as a whole. --- Sheena Erete, Editor
This Isn't Your Data, Friend
While research has been conducted with and in marginalized or vulnerable groups, explicit guidelines and best practices centering on specific communities are nascent. An excellent case study to engage within this aspect of research is Black Twitter. This research project considers the history of research with Black communities, combined with empirical work that explores how people who engage with Black Twitter think about research and researchers…

The evolution of agro-urbanism
The vast agro-urban settlements that developed in the humid tropics of Mesoamerica and Asia contained both elite civic-ceremonial spaces and sprawling metropolitan areas. Recent studies have suggested that both local autonomy and elite policies facilitated the development of these settlements; however, studies have been limited by a lack of detail in considering how, when, and why these factors contributed to the evolution of these sites. In this…
Ethics in Archaeological Lidar
Airborne laser scanning or lidar has now been used by archaeologists for twenty years, with many of the first applications relying on data acquired by public agencies seeking to establish baseline elevation maps, mainly in Europe and North America. More recently, several wide-area acquisitions have been designed and commissioned by archaeologists, the most extensive of which cover tropical forest environments in the Americas and Southeast Asia. I…
Top-down and bottom-up water management
The Greater Angkor region, in northwestern Cambodia, was home to several successive capitals of the Khmer Empire (9th to 15th centuries CE). During this time, the Khmer developed an extensive agricultural and water management system characterized by top-down state-sponsored hydraulic infrastructure. Archaeological evidence now shows that the well-documented state temples and water management features formed the core of an extended settlement comp…
Using ground penetrating radar to understand the failure of the Koh Ker Reservoir, Northern Cambodia
Ground penetrating radar, probing, and excavation were used to create a contour map of the topography of a buried laterite pavement forming the spillway of a large abandoned reservoir at the Angkorian‐period city of Koh Ker in Cambodia. Calculations of the flow velocity of water through the spillway, based on the topography of the laterite surface, demonstrate that this outlet was even less adequate for passing the flow of water from the Stung Ro…
Lines of Communication
Turquoise has played an important role in the Southwest, both today and in the distant past. Increasingly, archaeologists are coming to appreciate that the mineral was likely valued for its symbolism, rather than its chemical properties or economic worth. Thus, the color blue-green and a variety of blue-green things may have been conceptually analogous, together referencing and petitioning moisture. J. J. Brody recognized that additional symbols,…
Evidence for the breakdown of an Angkorian hydraulic system, and its historical implications for understanding the Khmer Empire
This paper examines the construction and design of a 7-km long embankment, probably built for King Jayavarman IV between 928 and 941 CE, as part of a new capital. We calculate that the capacities of the outlets were too small, and conclude that the embankment failed, probably within a decade of construction, so that the benefits of the reservoir stored by the embankment and the access road on top of it were lessened substantially. We explain how …
