A thousand-year-old agricultural system built for the future.
Xochimilco · Ciudad de México
One system
In a chinampa, the water, the soil, the food, the family and the ecosystem are not separate concerns. They are one loop — and it has been turning for a thousand years.
20,922 chinampas.
17% active.
A significant share of the inactive chinampas could be brought back into production — if cultivating them is economically viable for the people who know how. Source: project documentation, Xochimilco chinampa census figures.
The place
South of Mexico City, a lake landscape still farms itself.
What is a chinampa?
An island built to farm — anchored, not floating.
Lake and canal system
Everything begins in the water: the canals irrigate, connect and transport.
Sediment and organic matter
Lake mud and vegetation are layered into a raised bed of extraordinary fertility.
The raised bed — the chinampa itself
Above the waterline, drained and irrigated at once by the canals that surround it.
Ahuejote roots — living anchors
Willows planted along the edges hold the island to the lakebed. Structure, not decoration.
Water and nutrient cycling
Moisture rises through the soil profile; nutrients return with each dredging of the canal.
Polyculture and harvest
Many crops, all year. Chinampas produce more food per unit area than conventional farming while building soil rather than depleting it.
Biodiversity and restoration
Filtered water, habitat for endemic species — the axolotl among them — and a loop that regenerates itself.
"Floating gardens" is a common nickname. Chinampas do not float.
The people
The knowledge never left. The chinamperos are still here.
Producers across Xochimilco and San Gregorio Atlapulco cultivate, restore canals and pass the system on — organised in networks like Ruta Lacustre, several of them certified under UNAM's Etiqueta Chinampera.

The producer networks
Ruta Lacustre · Xochimilco
Collective work: production, fairer commercialisation, restoration and the transmission of knowledge between generations.
The daily work
Soil · Seedbeds · Canals
Chapines cut from lake mud, almácigos under shade, canals dredged by hand — techniques that predate the country they feed.
The food
Grown in soil the lake built.
Native maize, beans, greens, herbs and flowers — harvested from restored chinampas and moved to the city through NUMU Market. Seasonal, regenerative, traceable to the plot.
Why demand matters
When the market link weakens, the whole loop slows.
Economic viability and ecological restoration are not parallel workstreams. They are the same loop. Recurring demand is what keeps it turning.
The ecosystem
Who does what.
Brigades
A day of real agricultural labour, in an extraordinary place.
Brigades plant, clean canals and rebuild soil alongside the chinamperos. They are not corporate volunteering theatre — they are how people come to understand the system, and stay.
Participation
How companies take part.
Purchase
Create stable demand
Recurring produce baskets for your teams, or B2B sourcing through NUMU Market. Predictable orders are what let producers plan a season.
