Drained Fields at La Tigra, Venezuelan Llanos: A Regional Perspective

Abstract

This paper discusses drained-field studies in Venezuela, beginning with the first investigations two decades ago that focused on field systems themselves and proceeding to recent research by the authors that examined the drained fields of La Tigra as part of a regional-scale project in the state of Barinas. The La Tigra fields are dated to the Late Gaván phase (A.D. 550-1000), a time of extensive habitation in the region. An analysis of excavated pollen samples from the drained fields and a nearby village site has revealed that whereas maize was the predominant plant, there was notable intersite variability in the secondary cultigens. The paper also considers whether population pressure could have prompted the construction of the La Tigra fields. A comparison of archaeological population estimates to estimates of potential population under varying assumptions of productive capacity yields no indication of demographic pressures. We suggest that drained-field construction in this case was motivated primarily by political-economic considerations, part of a strategy whereby the regional elite sought to stimulate and mobilize the production of surplus by village farmers.
