We report core stratigraphy and chronology that explains the diachronic history of the surface in a prehispanic wetland agricultural complex of planting platforms and canals at Mandinga, central Veracruz, Mexico. Using recognizable stratigraphic horizons, elevations of prehistoric surfaces were measured for the wetland prior to the construction of platforms and canals, immediately following construction, at the time of abandonment, and of the present-day surface. Significant topographic and hydrological changes are evident. We discuss our results in the light of prehispanic water (...) management and cultivation and postulate water storage within the wetland, a patchy management of water and cultivation, and variable productivity. The paper ends with a discussion of the lessons that can be learned when contemplating contemporary cultivation of wetlands. In addition to the environmental concerns, we emphasize the need to consider the physical, socio-economic, and political contexts in which contemporary wetland agriculture would have to operate.
