the Digital Archaeological Record (tDAR) and Digital Antiquity

(Kintigh and Pierce-McManamon, lead)




The LTVTP is a key component of a project known as IHOPE (Integrated History [and Future] of People on Earth (Costanza et al. 2007), which is sponsored by the International Human Dimensions Programme and supported by the Resilience Alliance. The overarching goals of IHOPE are to map an integrated record of biophysical and human change on earth over the last several millennia, develop and test models with this integrated history, and develop policy recommendations. To this end, IHOPE is assembling a massive transdisciplinary database of historical and environmental processes in different parts of the world, including the LTVTP in the Southwest and Northwest Mexico, the ARCHAEOMEDES archaeo-ecological dataset from southern Europe (van der Leeuw 1998, 2005) and ongoing work on the Maya. The synthetic data available on this website are representative of the LTVTP’s presence on IHOPE. Eventually, the IHOPE database will provide in-depth yet synthetic understandings that allow researchers from different disciplines to integrate and compare information from a variety of cases.

Legacies on the Landscape

The Legacies on the Landscape project is a collaborative effort by archaeologists and ecologists at Arizona State University to investigate the legacy of prehistoric human land use on the mesas of Agua Fria National Monument north of the Phoenix Basin. The goal of the project is to build theory about what types of human disturbances leave legacies over different time scales, and gain insights into the ways that today’s actions can affect future ecological systems. The project is headed by archaeologists Katherine A. Spielmann and ecologists Sharon J. Hall.

Change is Hard: The Challenges of Path Dependence

The LTVTP is linked to a transdisciplinary project called Change is Hard: The Challenges of Path Dependence, which is part of the Late Lessons for Early History transdisciplinary program in SHESC. Change is Hard brings together a transdisciplinary group of scholars who are investigating historical trajectories at different scales across the greater Phoenix area, seeking lessons and policy implications from the recent, historical, and ancient past. Given a particular configuration (whether of contemporary Phoenix or the Hohokam Classic), the research asks "How did we get here," with focus on the overall trajectory and particularly on critical junctures, times when certain decisions set the course that affected generations to follow. The link between LTVTP and Change is Hard mostly involves Hohokam research. In particular, Hegmon and others are investigating the labor involved in the start-up of the major canal systems, to understand when and how the trajectory developed momentum. The other faculty leading Change is Hard are Bob Bolin, Jameson Wetmore, and Abigail York.
