Southwest US

The empirical component of our research involves five prehispanic sequences in the southwestern US and northern Mexico; these range from 500 to 750 years and represent climate, environmental, and cultural changes of varying magnitudes.

Project description

The Southwest Case in IHOPE is a product of research by the Long-term Vulnerability and Transformation Project (LTVTP), based at Arizona State University and involves researchers from many institutions.  The LTVTP uses the deep time of the archaeological record to develop general understandings of factors that contribute to resilience and vulnerability, to stability and transformation, and to the characteristics of various types of change, including transformations, that are costly and/or painful to the people and environments involved. It draws on the resilience perspective, as well as on recent literature on robustness-vulnerability tradeoffs. A recently funded initiative of the LTVTP project builds upon this research by examining how social and ecological diversity interact to influence the resilience of societies facing major changes in their social or environmental circumstances. The goal is to discover configurations of diversity in ecological landscapes and in forms of social organization that make systems more or less able to cope with significant environmental or social changes without undergoing an unpleasant transformation.

Map of the LTVTP case study areas

Empirically, the LTVTP focuses on five archaeologically known cases that together span the period from AD 450 to 1600 in the southwestern US and northern Mexico. The cases are investigated individually and comparatively, and theories about general processes affecting vulnerability and transformation are investigated by working iteratively between archaeological analysis, mathematical modeling, and institutional analysis. Thus the project involves collaboration among experts in archaeology, mathematical modeling, ecology, and institutional analysis.

There is clear archaeological evidence that these earlier pueblos had been abandoned for some time before the larger pueblos were established in the 1400s. The more vulnerable location of these earlier villages was probably an important factor in their abandonment. (read more)
