Floating Gardens of Xochimilco
Central-South Mexico Region
The Floating Gardens of Xochimilco, known as chinampas, are an ancient Mesoamerican agricultural technique developed in the Valley of Mexico. These artificial islands were created by weaving reeds into underwater fences, then layering soil and vegetation to form fertile plots on shallow lake beds. Primarily used by the Aztecs, chinampas allowed for highly productive farming with multiple harvests annually, sustained by an ingenious drainage and fertilization system that recycled nutrient-rich lake sediments. Trees such as willows and cypresses were planted at corners to stabilize the plots. Today, these gardens represent a unique cultural landscape and agricultural heritage, recognized by the United Nations as a Globally Important Agricultural Heritage System. The system exemplifies sustainable farming practices and offers insight into pre-Hispanic agricultural innovation in Central Mexico.

Interesting facts
- •Chinampas can yield up to seven harvests annually, far surpassing typical farming cycles.
- •The word 'chinampa' means 'in the fence of reeds' in the Nahuatl language.
- •The United Nations designated the chinampa system a Globally Important Agricultural Heritage System in 2018.
- •Trees like Salix bonplandiana (willow) and Taxodium mucronatum (cypress) were planted at chinampa corners to stabilize the soil.

History
Chinampas date back to at least 1100 CE, with the Nahua settlement of Culhuacan credited with early constructions.
The Aztecs later expanded and refined chinampa agriculture on a large scale, especially after conquering Xochimilco and other southern basin city-states.
This system sustained dense populations by enabling up to seven harvests per year.
Over centuries, the technique evolved with sophisticated water management and soil enrichment methods.
Despite urbanization threats, the chinampas have persisted as a living agricultural tradition, maintaining their ecological and cultural significance into the modern era.
