Such as the Aztecs and modern urban agriculture
Roland Ebel of the Sustainable Food Systems could improve program at Montana State University led to define a research project, the extent, to benefit the, an old Aztec agricultural technique could 21st century gardening needs.
Specifically, Ebel examines the use of “coming” with the hope that the discovery of their modern utility. A chinampa is a raised box on a small artificial island in a freshwater lake (surrounded by canals and ditches), in which vegetables can be produced year-round. The irrigation needs for the coming of is low, and the productivity is extremely high. Coming to offer fresh products for a megacity such as Mexico city and are conceivable to many of today’s exploding urban areas.
Ebel results are shown in the article “coming: An Urban Farming-a model of the Aztecs and a Possible solution to the Modern Megalopolis”, the open access to the online journal HortTechnology.
The chinampa system, the gardens, commonly referred to as floating, is still practiced in some suburban areas in Xochimilco in the South of the valley of Mexico city These raised fields were created by digging the canals and mounding the displaced earth on platforms. Similar historical raised systems can be found in South America, Asia, Oceania, and parts of Africa.
In the chinampa, the canal water rises by capillary action to the roots of the plant, the irrigation reduces the demand. In addition, a significant part of the soil fertility is generated in the channel floors. Complex rotations of up to seven crops in a year. Coming of also provide ecosystem services, in particular, greenhouse gas sequestration and biological diversity. In addition, the recreational benefits are enormous: today, the largest city generate more money from tourism than horticultural production.
Ebel in front of the chinampa, one of the most intense and most productive production systems ever developed, and it is very sustainable. It can be kept in almost continuous cultivation, and the micro-climate is favorable for many horticultural crops including ornamental plants, which play an increasingly important role in Xochimilco. Even small animals can be triggered, on the coming of.
During the Aztec period (1325-1521), the development of the largest city’s high-density population and the growth of significant local urban communities. The increased area of agriculture is available to pre made-Columbian farmers with better drainage, soil aeration, moisture retention during the dry season, and a higher and longer-term soil fertility than in conventional outdoor production.
“Today, many cities are confronted with very similar challenges as Mexico city has 700 years of ag — a fast-growing population and less arable land available for food production Very intensive production systems with low-resource requirements are, therefore, a strategic objective of the urban agriculture developers. So while most of the strategists emphasize the high-tech solutions, such as complex vertical farms, I think it’s worth to learn from the achievements of our ancestors,” says Ebel.
Yet, in spite of the various efforts and to interpret the coming of the raised-field production system is now mostly limited to small-scale projects in research and development.
Ebel supports the efforts for revitalization of the chinampa system. “A restored use of the coming of the intensive production of fresh vegetables would allow in the vicinity of Mexico city, the avoidance of transportation needs and the avoidance of negative consequences on the quality of produce and the emissions of greenhouse gases,” he says.
In addition, coming of could services a number of desired ecosystem, including water filtration, regulation of water levels, the micro-climate regulation, increased biodiversity, and carbon sequestration and storage. Ebel adds: “Wherever you freshwater lakes in the vicinity of a large city, chinampa-like systems are conceivable — and this applies to many parts of the world.”
The advantages of the creation of the largest city are not limited to the big cities, although the support, it could be urban farming would be difficult to overestimate. This system could be adopted in smaller rural communities, particularly in tropical wetlands.
