How Mexico City is turning into a farmland Oasis – GREENING THE CITY PROJECT


Mexico City is the 5th largest city in the world with population of around approximately 22 million, which classifies Mexico city as a mega city.

It is situated in the The Central Mexican Plateau, at 2,240m in elevation. Mexico city is also slowly sinking at a rate of about 10 inches per year! The entire metropolis is built on top of a lake bed and the city pumps draw water from it. The ground below is sandy and unstable, which amplifies even small earthquakes by as much as 500%.

All these factors have caused problems in the last decades with regards to the urban infrastructure, water management and waste disposal. Mexico City is the second biggest producer of waste among the world’s mega cities more than Half of this waste is produced at homes and 2,400 diesel-powered garbage trucks which are old and inefficient circulate the city every day. With approximately 90% of all household trash ending up in landfills, which emit methane, a potent greenhouse gas, accounting for 10% of global emissions. Severely impacting the health of the people and the environment.

Mexico cities population has been growing exponentially in the last century
and as a result water and waste management has been in a crisis along with the challenges of feeding a growing population.

However in recent years the local people of Mexico City have been turning this around. In this video we will show you how abandoned land has been turned into a green waste management system using an innovative Mexican technology that reduces co2 emission in the recycling process as well as creating a social and educational space for the community.

In the district of Roma Sur in Mexico City, the local residents have been tackling these challenges head on by creating a green oasis in the city that can deal with food, water, waste management and bioconstruction. This place is called Huerto Roma Verde and covers an area of nearly 8,000 square meters, which used to be part of a housing estate of several apartment buildings that were destroyed by the major earthquake of 1985.

For 27 years the plot was a wasteland and used by neighbors as a dumping ground for their rubbish. Until a man named Paco Ayala who grew up in the Roma neighborhood decided to transform the wasteland into the socio-ecological experiment, where zero waste ancestral sustainable knowledge is being revitalized.

Mexico City was the Ancient Capital of the Aztecs and was known as Tenochtitlán, it was considered a mega city for its time and was a completely zero waste society. Incredibly no records of Aztec trash sites have been found. Instead they developed a resource-efficient culture with a highly-productive agricultural system that recycled nutrients from their waste products. The Aztecs did this by expanding the chinampas, or artificial islands. Which were the invention of the several indigenous tribes related to the Tolteca who had already been living around the lakes since 100 AD

The Aztecs demonstrate that a society can successfully adapt to dramatic changes in environmental conditions and build a strong economy by making an efficient use of resources and not wasting anything.
