Research on hunting and gathering peoples has given anthropologists a long-standing conceptual framework of sedentism and mobility based on seasonality and ecological constraints. This work challenges that position by arguing that mobility is a socially negotiated activity and that neither mobility nor sedentism can be understood outside of its social context. Drawing on research in the Mesa Verde region that focuses on communities and households, Mark Varien expands the social, spatial, and temporal scales of archaeological analysis to propose a new model for population movement. Rather than viewing sedentism and mobility as opposing concepts, he demonstrates that they were separate strategies that were simultaneously employed. Households moved relatively frequently--every one or two generations--but communities persisted in the same location for much longer. Varien shows that individuals and households negotiated their movements in a social landscape structured by these permanent communities. Varien's research clearly demonstrates the need to view agriculturalists from a perspective that differs from the hunter-gatherer model. This innovative study shows why current explanations for site abandonment cannot by themselves account for residential mobility and offers valuable insights into the archaeology of small-scale agriculture.

Beginning about A.D. 1250, the Zuni area of New Mexico witnessed a massive population aggregation in which the inhabitants of hundreds of widely dispersed villages relocated to a small number of large, architecturally planned pueblos. Over the next century, twenty-seven of these pueblos were constructed, occupied briefly, and then abandoned. Another dramatic settlement shift occurred about A.D. 1400, when the locus of population moved west to the "Cities of Cibola" discovered by Coronado in 1540. Keith W. Kintigh demonstrates how changing agricultural strategies and developing mechanisms of social integration contributed to these population shifts. In particular, he argues that occupants of the earliest large pueblos relied on runoff agriculture, but that gradually spring-and river-fed irrigation systems were adopted. Resultant strengthening of the mechanisms of social integration allowed the increased occupational stability of the protohistorical Zuni towns.
