Definitions

1. An ancient agricultural technique from Mesoamerica involving the creation of floating islands for cultivating crops efficiently on water surfaces
2. A sustainable farming method originating in Mexico that utilizes raised beds constructed on aquatic environments for crop growth
3. A type of raised agricultural plot built on shallow lake beds to grow crops using a water-based system

Etymology: Chinampas were not really floating islands in the sense the definition suggests. They were rectangular plots built up from lake mud and vegetation, fenced in with woven cane, and anchored among the shallow lakes of the Valley of Mexico. The name comes from Classical Nahuatl "chināmitl," meaning "cane fence," which points to the most visible part of the system: the reed barriers that held the soil in place. Spanish speakers adopted the term as "chinampa," and English borrowed it from Spanish. The fields were fertile because the builders layered mud dredged from the lake bed with decaying plants, creating rich, well-watered soil that could be cultivated year-round. Canals ran between the plots, so farmers could reach their crops by boat, and the water kept the ground moist even in dry seasons. Gardeners grew maize, beans, squash, chilies, and flowers on them. The most striking thing about the term is that the Nahuatl word names the fence rather than the field. Speakers picked out the cane barrier as the defining feature, and the agricultural system took its name from that structure.
