Chinampa Agriculture in the World Natural and Cultural Heritage Zone in Xochimilco, Tláhuac and Milpa Alta

Summary

The chinampas agricultural system is an articulated set of floating artificial islands built in a traditional way based on oral transmission chinampera prevailing culture since Aztecs times.

 

They offer high agricultural productivity (grown up to 5 times a year) and great ecological importance, surrounded by canals and ditches and rows of "ahuejotes" (Salix Bonplandiana) native willow species that performs several functions, such as  serving as fencesfor wind and insects, providing habitat for birds, and keeping the soil in the plots, whose roots protect the borders or edges of chinampa from erosion.

 

Faced with climatic contingencies such as frost or variation in rainfall, chinampera agriculture offers an example in which agroecological intensification  can co-exist with urban development and the revitalization of the heritage by linking social networks, which develop technological strategies and promote solidarity and a sense of community.
