Multiproxy paleoecological reconstruction of prehistoric land-use history in the western region of the lower Río Verde Valley, Oaxaca, Mexico

Paleoecological archives from three paleomeander sites and one archeological feature located in the lower Rio Verde Valley, Oaxaca, Mexico, are used to develop a spatial understanding of the patterns of prehistoric agricultural land use over the last ~3000 years. Multiproxy paleoecological data at each site (i.e. magnetic susceptibility, micro- and macroscopic charcoal, pollen and stable carbon isotopes) provide a history of land use. By examining the spatial differences in agricultural indicators at all the sites through time, augmented with our understanding of changes in demography and settlement patterns determined through the archeological record, we are able to reconstruct the complex human/land interactions in the western portion of the valley.
