Mexico’s Chinampas – Wetlands Turned into Gardens – Fight Extinction

XOCHIMILCO, Mexico , Feb 27 2016 (IPS) – David Jiménez grows two kinds of lettuce and other fresh produce on his “chinampa” or artificial island just under one hectare in size in San Gregorio Atlapulco, on the south side of Mexico City.
“We can get five or six harvests a year. Lettuce can grow in 30 days,” Jiménez, the president of the six-member La Casa de la Chinampa cooperative, told IPS with evident enthusiasm. The cooperative operates in Xochimilco, one of Mexico City’s 16 boroughs.
The ejido – land held in common by the inhabitants of a village and farmed cooperatively or individually – where Jiménez has his farm covers 800 hectares, and is home to 800 farmers who mainly grow vegetables. Half of the ejido is made up of chinampas.
The system of chinampas dates back to the Aztecs, long before the arrival of the Spanish conquistadors in the 15th century. The technique creates small, rectangular gardens reclaimed from Mexico City’s marshy lakebed by piling up soil on a mat of sticks, using wattle as fencing and willow trees at the corners to secure the bed.
The chinampas are rich in muck and decaying vegetation, which provide nutrients for the crops, while the ditches between them give the plants continuous access to water. As a result, the vegetables grown there are especially rich in nutrients.
The chinampas, which help feed the 21 million people who live in Greater Mexico City, are in the boroughs of Milpa Alta, Tláhuac and Xochimilco.
Worked by some 5,000 farmers, the chinampas cover a total of 750 hectares. The system is profitable, because they produce a combined total of around 80 tons a day of vegetables.
Each head of lettuce fetches 10 cents of a dollar, Jiménez said, as he tended to a row of lettuce.
The chinampas or “floating gardens” produce spinach, chard, radishes, parsley, coriander, cauliflower, celery, mint, chives, rosemary, lettuce and purslane or pigweed. Visitors to the area walk along paths that take them across a green carpet segmented into rectangles of crops and divided by the ditches of water they depend on to grow.
The drought-resistant system uses less water than traditional irrigation and produces fish, vegetables, flowers and medicinal herbs.
Studies also show that the chinampas repel pests, are more productive than conventional agricultural systems, and produce biomass. The technique is completely sustainable, retaining moisture and regulating the microclimate in the area.

Ricardo Rodríguez, founder and director of the company De la Chinampa a tu Mesa (“from the chinampa to your table”), came up with a way to link traditional production techniques with new technologies, by marketing the vegetables grown on the chinampas over social networks.
He picks up fresh produce in the Cuemanco natural area in Xochimilco, signs up customers on his web page, processes the purchases, and distributes the orders to the customers’ homes.
“We help generate demand, which motivates them to keep farming. And this helps restore the chinampas. The market is starting to recognise the value of the chinampas,” Rodríguez told IPS.
The entrepreneur works with 22 “chinamperos” or chinampa farmers who grow broccoli, spinach, beets, radishes and other crops on approximately 15 hectares. He delivers some eight orders a day, weighing eight kg on average. His 450 registered customers include stores and restaurants that sell organic food.
Xochimilco, which is home to more than 415,000 people on some 125 sq km, was named a World Heritage Site by the United Nations Educational, Scientific and Cultural Organisation (UNESCO) in 1987.
In addition, the Ejidos de Xochimilco and San Gregorio Atlapulco Lake System have been on the Ramsar ConventionList of Wetlands of International Importance since 2004.
The U.N. Food and Agriculture Organisation (FAO) selected the chinampas as a Globally Important Agricultural Heritage System (GIAHS), because they preserve agricultural biodiversity, help farmers adapt to climate change, bolster food security and reduce poverty.
Marco Covarrubias, the head of the Gastronomy Centre at the private Claustro de Sor Juana University based in Mexico City, stresses the importance of the chinampas in terms of food production.
“The advantage is that they are in permanent contact with water, which unlike in other systems is not used to irrigate but is absorbed by the plants,” he told IPS. “And they have added nutritional value because a large part of the chinampas is free of pesticides and other agrochemicals.”
Urban sprawl and expanding slums, the use of pesticides, climate change, excessive use of groundwater, and neglect have all contributed to the destruction of the chinampas, says a study by the Natural and Cultural Heritage of Humanity Zone Authority (AZP) in Xochimilco, Tláhuac and Milpa Alta.
The AZP, created in 2014, is in charge of managing the preservation of this special ecosystem, in order to maintain the UNESCO and Ramsar Convention designations.
“Any effort to protect the area must take into account the local farmers and the cultural environment surrounding the chinampas. This is a culture that is not really appreciated, the restoration plans haven’t been carried out,” said Jiménez.
His cooperative decided to create a model farm on two hectares of their land, to show visitors the benefits of the chinampas.
And on Feb. 22, it launched a programme in local schools, which includes a virtual tour of the chinampas. With some 6,400 dollars in public funds, the idea is to raise awareness among 6,000 students in primary and secondary schools in Xochimilco.
The environmental authority is facing cuts, which have hurt its efforts to protect the region. Its budget shrank from 700,000 dollars in 2015 to 400,000 dollars this year. Since 2013, the AZP has supported 174 environmental and cultural improvement projects, but there is no clear information about the specific impact on the chinampas.
In March 2014, the French Global Environment Facility donated 1.65 million dollars for the conservation of the area.
In an October 2014 report, “Rehabilitation of the chinampera network and the Xochimilco native species habitat,” the Biology Institute of the National Autonomous University of Mexico said restoration of the chinampas should be a priority, because of their ecological, economic and social importance.
It recommended promoting the concept of chinampa-nature reserve, “because this represents multiple benefits for improving water conditions while giving a boost to sustainable productive activities as a strategy to prevent encroachment by urban sprawl.”
Covarrubias, meanwhile, said “Greater attention should be paid to the chinampera zone; it should be studied as an area of extremely high production potential, and a public policy should be created to link people who live in, and make a living from, the chinampas, with direct buyers.”
Since 2014, his university has organised the La Chinampería programme, to hook up local farmers and buyers. And this year it is carrying out another applied research plan to foment value chains, with the participation of 15 chinampa farmers.
“Awareness-raising programmes are needed for their descendants to start to recuperate the chinampas, improve the cleaning system, and acknowledge the farmers,” said Rodríguez, the entrepreneur, who organises “consciousness-raising tours” on the role of the chinampas in food security and the importance of small-scale local agriculture.
He wants to create a market of producers in Cuemanco, generate a label for goods produced in Xochimilco, to boost the prices of local products, and set up a collection centre for the products.

Chiranthodendron pentadactylon - Devil's Hand, Mācpalxōchitl, Canac
OVERVIEW
The Genus Chiranthrodendron comprises a single species, C. pentadactylon. The tree is called the Devil's, monkey's or Mexican hand tree or the hand-flower in English, the árbol de las manitas (tree of little hands) in Spanish, and mācpalxōchitl (palm flower) in Nahuatl, all on account of its distinctive red flowers, which resemble open human hands.Common names include Arbol de las Manitas (Spanish), and mācpalxōchitl (palm flower) in Nahuatl.
Chiranthodendron leaf.
Origin and distribution
The tree is most common in the subtropical highlands of Mexico, less commonly found in Guatemala. I propagated the seed and planted it in Northern California just north of San Francisco. The tree seems to thrive in the cloud-forest-like redwood covered hills. The tree gave a few flowers in its fourth year, a few more in the fifth, and now on its sixth year from seed it is close to 50 feet tall and flowering profusely in June.
USES AND ETHNOBOTANY
From what limited ethnobotanical information I can find: solutions containing the tree’s flowers are used as remedy for lower abdominal pain and to treat heart ailments. Similar solutions are used to reduce edema and serum cholesterol levels and are used as diuretics. The flowers can still be found sold in markets in Mexico and Guatemala, commonly referred to as “Manitas” or little hands.
It has also been documented that parts of the plant were used to flavor the traditional cacao beverage by the Aztecs in the 16th century.
Apparently the leaves are edible, and traditionally used to wrap tamales and cheese, said to impart a distinct flavor.
The lower saucer portion of the flower contains up to a few tablespoons of sweet syrup with a flavor reminiscent of burn caramell / sugar.
The bark can be used to make rope.
Chiranthodendron has a seedpod not dissimilar in form to the Starfruit. This pod is, however, extremely durable, making it challenging to extract seeds from an unopened pod.

Pseudobombax ellipticum - Shaving Brush Tree, Amapolla
OVERVIEW
Pseudobombax ellipticum, is a species of plant in the Bombacoideae subfamily of the Malvaceae family. known in English as Shaving Brush tree (in reference to the flower) is native to Mexico and Central America where it is referred to variously as Acoque, amapola, árbol de doncellas, árbol de señoritas, calinchuche, jilinsuche, matías, pilinsuchil, pumpo, shaving bush, shilo, shilo blanco, shilo colorado. I took these photos in Jalsico, Mexico where it is called Clavelina.
Mature trees grow to about 60 ft developing an engorged, bottle-shaped trunk.
USES
Uses include firewood and wood for carving handicrafts.
The attractive flowers are used to decorate homes and churches in Central America. In Central America, a highly intoxicating drink is made from the tree.
