Ancient settlement, urban gardening, and environment in the Gulf lowlands of Mexico

Urban settlement in the western lower Papaloapan River basin in the Gulf lowlands was dispersed and likely employed intensive gardening near domiciles. Land surrounding homes also may have played a symbolic role in these agrarian societies. Water works-formal ponds associated with temple platforms and other prominent structures as well as with many residential mounds-support the idea of symbolic as well as practical functions in land use around buildings. Dispersed occupation occurs in low elevations suited to recessional planting, a technique that takes advantage of dry season ground moisture in low areas where rain and flood waters recede as the water table drops. We analyze elevational zones to show greater settlement density in the low-lying Blanco River delta than in higher elevations up river Analysis of distances between archaeological residences and wetlands and drainages shows that residences generally were close to seasonally flooded areas. We also highlight anthropogenic qualities in the alluvial landscape, offering a land use perspective distinct from other views of agricultural intensification. The settlement pattern is compatible with Mesoamerican forms of urbanism.
