Mesoamerican Cities and States
Mesoamerica repeatedly produced large cities and states without draft animals, wheeled freight, or one continuous imperial center. Dense settlement depended on intensive land use, water management, markets, records, and negotiated political authority.
The five claims begin with lidar’s regional view of Maya settlement, then test ecological engineering, writing, exchange, and what political collapse changed—and did not erase.
Key Insights on Mesoamerican Cities and States
Lidar mapped 61,480 ancient structures across 2,144 square kilometres of northern Guatemala.
Maya cities were embedded in a densely built countryside
The forest did not hide a few isolated ceremonial centers. It hid roads, terraces, fortifications, buildings, and fields spread across an intensively modified region.
The strongest conclusion is spatial: urban cores and rural settlement formed one connected landscape. The modeled population totals are useful, but more assumption-dependent than the mapped structures beneath them.
Maya cities were embedded in a densely built countryside
Airborne lidar mapped twelve blocks in the Maya Biosphere Reserve of northern Guatemala.
survey footprintThe classification counted buildings, platforms, roads, fortifications, terraces, and other features.
mapped feature countThe mapped total averages twenty-nine classified structures per square kilometre across the survey.
survey-wide ratioThe authors modeled average population density for the central Maya Lowlands at their Late Classic height.
regional modelThe modeled density implies seven to eleven million people across the larger central lowland region.

Evidence standard
The first visual reproduces the headline results of the 2016 PACUNAM lidar survey published by Canuto and colleagues. Structure counts come from the 2,144-square-kilometre sample; population figures are models extended to the larger central Maya Lowlands.
The second compares four site-level water and land systems. Survey areas, dam dimensions, infrastructure descriptions, and functional interpretations retain their original scopes; they are not combined into one engineering score.
