Mexico City has announced that it will take steps to protect more than 60 maize breeds known to grow in its territory, also known as the Mexican Altiplano. The announcement came just days before the Mexican Government said that it would allow the experimental cultivation of genetically modified (GM) maize in other parts of the country. The first announcement was made by Marcelo Ebrard, mayor of Mexico City, in regulations known as the 'Declaration of Protection of the Maize Breeds of the Mexico Altiplano'.
"The Altiplano is one of the centres of maize domestication," says the decree. "There the Teotihuacan, Tolteca and Mexica cultures have their splendor and contributed to the integration of Mesoamerican agriculture." Maize is Mexico's staple food. Half of Mexico City territory is agricultural and around 3,000 hectares are cultivated with maize every year.
The declaration says that a research programme will be established with the aim of improving local maize breeds. There will also be funds to support farmers who sow only native seeds and to promote the use of organic fertiliser and pesticides. The purchase and distribution of transgenic maize in Mexico City is now banned.
Esther Orozco, director-general of the Institute of Science and Technology of Mexico City, says that genetic modification is controversial and generates opposing opinions, but Mexico City is the world's "maize capital" and it is important to take care of native species: "It is necessary to increase the research to know the real effects of the transgenic maize in crop biodiversity."
