Mexico’s Floating Gardens Are an Historic Surprise of Sustainable Farming


Waterline is an ongoing collection of tales exploring the intersection of water, local weather and meals, informed by the eyes of the individuals impacted by these points. It’s funded by a grant from the Walton Household Basis.

Standing amid rows of juicy, lime inexperienced lettuce and chunky florets of broccoli, Jose Paiz seems as if he might be the proprietor of a contemporary, high-tech farm. However the crops thriving right here, within the suburbs of Mexico Metropolis, are a part of a 1,000-year-old custom.

“My ancestors had been doing this earlier than even the [Spanish] Conquistadors arrived in Mexico [in 1519],” says Paiz, whereas crouching down to select up a handful of powdery soil from the chinampa, or “floating backyard,” on which we’re each standing.

These extremely productive man-made island-farms, which will be discovered floating on lakes throughout the south of Mexico’s capital, date again to the time of the Aztecs or maybe even earlier — and now proponents say that these historical engineering wonders might present an necessary, sustainable meals supply as the town faces historic drought.

“My grandparents taught me the strategies,” provides Paiz, 32, who’s the fifth era of his household to be a chinampero working in San Gregorio Atlapulco, a standard working-class neighborhood about 10 miles south of the middle of Mexico Metropolis.

Consultants say that these chinampas, which have been acknowledged as a UNESCO World Heritage web site, are thought-about one of the productive agricultural programs on this planet. The bogus islands are constructed by gathering giant quantities of soil from the underside of the lake and putting it on prime of reeds, grasses and rushes in a mass that rises above the water. Farmers then plant a fence of ahuejotes, Mexican willow timber, across the plot to naturally shield towards erosion. This technique implies that the chinampa’s soil is continually enriched by nutrient-filled sediment flowing in from the encompassing ditches and canals, yielding a number of harvests yearly.

“By way of agriculture, they’re top-of-the-line examples of how people can work with nature,” says Lucio Usobiaga, founding father of Arca Tierra, a company offering native farmers within the space with technical and entrepreneurial assist.

One of many first traces of the chinampas dates again to the 14th century, when the Aztecs arrived on the area of what’s now modern-day Mexico Metropolis. There, they based the settlement of Tenochtitlán — which might turn out to be one of the highly effective cities in all Mesoamerica — within the Valley of Mexico. 

However because the Aztecs quickly found, the valley’s boggy, lake-filled panorama was tough to domesticate or construct on. In order that they devised an ingenious plan to adapt to the environment: the chinampas.

A 2013 paper by North Carolina State College professor Matthew Teti discovered that within the sixteenth century, chinampa farms might produce 13 instances as a lot crop as dry-land farming in the identical space — a system that supplied meals for a whole lot of 1000’s of individuals. Chinampas, the examine stated, are “one of the intensive and productive agricultural programs ever devised.”
