3 - Archaeological methods for the study of ancient landscapes of the Llanos de Mojos in the Bolivian Amazon

Summary

The archaeological study of agricultural systems

Archaeological gardens and field systems are notoriously difficult to study. They tend to be “artifact poor” contexts, and thus, extremely difficult to date with accuracy. Stratigraphy tends to be heavily reworked and eroded, the result of continual cultivation and mixing of soil structure by humans and nature, both during the time of use, and after abandonment. Due to the poor preservation of botanical remains, there is usually no direct evidence for the crops which were cultivated. Technological information on cultivation practices and tools is limited, and rarely is there direct evidence for labor and social organization, land tenure, and efficiency of the system.

Ethnographic analogy can be useful in many contexts, but it is usually difficult to determine direct historical ties between contemporary farmers and their previous counterparts. In many situations, ancient field and garden systems have been completely abandoned, breaking any continuity between past and present. Even in cases where ties can be demonstrated, the social, political, economic, and environmental situation has changed so much that the usefulness of direct analogy is limited. Historical records can sometimes be extrapolated back into the past, but agricultural practices are not often discussed in sufficient detail. Despite these limitations to research, certain archaeological field methods, combined with experimental archaeology, can provide the detailed information lacking in cases where historical and ethnographic analogy is inadequate and preservation is poor.
