Mayan_Agriculture

The ancient Maya had diverse and sophisticated methods of food production. It was formerly believed that shifting cultivation (swidden) agriculture provided most of their food but it is now thought that permanent raised fields, terracing, forest gardens, managed fallows, and wild harvesting were also crucial to supporting the large populations of the Classic period in some areas. Indeed, evidence of these different agricultural systems persist today: raised fields connected by canals can be seen on aerial photographs, contemporary rainforest species composition has significantly higher abundance of species of economic value to ancient Maya, and pollen records in lake sediments suggest that corn, manioc, sunflower seeds, cotton, and other crops have been cultivated in association with deforestation in Mesoamerica since at least 2500 BC.
