3.1. Reasonable maximum population of Palmyra The results indicate that a population of between 30,000 people could be comfortably supported by the hinterland of Palmyra at all times during its history (Fig 3). The maximum viable population falls between 65,000 and 90,000 (Table 1) people and assumes significant storage infrastructure to ensure food security despite annual fluctuations in agricultural production. Fig 3. Changes in the carrying capacity between 1–300 CE.
