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. The five cases are Zuni, Mimbres, Hohokam, Salinas, and La Quemada.

These cases represent a range of social forms and a range of environments that allow us to assess the impacts on different diversity conditions on long-term resilience, but all are all set in a similar climatic region that is semi-arid. All involve prehistoric agriculturalists in non-state societies in arid environments, but they vary in terms of specific environmental variables, degree of social complexity and size, and investment in water control.

Although the scope of potentially relevant knowledge from these regions is enormous, a firm foundation for our work is provided by extensive fieldwork, regional syntheses, and a rich tradition of studies linking environmental conditions and social dynamics.
