Ancient cities – "Instead of a small focal point, cities spread over 100 sq km."


From the linked article:

Amazingly, however, far from being compact, we now know that even in the most well-known of Maya centres, like Copán and Tikal, the population was relatively dispersed. Instead of having fields outside and politics inside, fields were located throughout the urban infrastructure and residences. And instead of a small focal point, cities spread over 100 sq km. Recent studies of Tikal have shown a network of moats, dwellings, reservoirs and pyramid clusters that extend out from a single hill for up to 200 sq km into the surrounding landscape.

Innovative aerial surveys have now made similar findings across the Maya world. In almost all instances, instead of isolated urban buds, scientists have found vast landscapes of small and large centres connected by dispersed agrarian landscapes, residential areas, causeways and a complex, interlinking system of dams, reservoirs, sinkholes, channels and swamps that supported growing populations through even the driest of seasons. As leading Mayanist Prof Lisa Lucero, of the University of Illinois, puts it, “the Classic Maya knew the importance of water and of fertile agricultural soils, the latter dispersed in variously sized pockets, mirrored by a dispersed agricultural settlement. This low-density approach to cities was a logical, innovative solution.”

The Classic Maya also had far more diverse and sophisticated economies than has often been appreciated. Alongside the key crops, archaeobotanists have shown that the planting of avocados, pineapples, sunflowers, tomatoes and manioc added to a dispersed settlement and lifestyle. The Classic Maya are also known to have penned, fed and fattened wild turkeys and deer for their key protein sources.

Scientists have found evidence that diverse “forest gardens” sustained these cities. Based on ethnographic study of, and testaments from, Maya communities today, this type of cultivation, called milpa (or kol in the local Yukatek language), involves the use of multiple crops, and the movement of fields, allowing different parts of the forest to grow back and patches of soil to rest and restock before planting begins in a locality again. We also know that instead of indiscriminately planting in soils of all types, the Classic Maya actually followed rich veins of particularly productive soils, giving their field systems a winding appearance that snaked along rivers and up slopes. They even added special plants, like water lilies, to reservoirs. These plants are incredibly sensitive to water quality, only growing under clean conditions, and allowed people to monitor the buildup of stagnant water and thus guard against disease.
