Chinampas are a traditional agricultural system developed by the Aztecs, an indigenous civilization in central Mexico known for its advanced agricultural practices and cultural achievements. These unique floating gardens have sustained communities in what is now Mexico City for centuries. Constructed using fertile mud from the lakebed, these islands have provided essential food supplies for the region. However, urbanization poses a significant threat to their existence. As the city expands, many local farmers are abandoning chinampa cultivation for more profitable ventures, such as soccer fields. According to Cassandra Garduño, a farmer committed to preserving this ancient practice, a decline in farming interest is evident. The low market value of produce from chinampas has led families to sell or lease their lands, undermining this vital cultural heritage.

Despite these challenges, initiatives to revitalize chinampa farming are emerging. Garduño has joined a collective known as Chinampa Refuge, which aims to promote sustainable practices and educate younger generations about the importance of these ecosystems. Recent studies by Luis Zambrano, an ecologist, emphasize the self-sustaining nature of chinampas, which can yield multiple crops without chemicals or extensive irrigation. Additionally, preserving chinampas contributes positively to the urban environment by supporting diverse wildlife and regulating temperatures. However, the transformation of agricultural land into recreational spaces raises ecological concerns, as the increased use of chemicals in these developments can harm the ecosystem. Efforts by local authorities are underway to regulate these activities and safeguard the chinampa system, ensuring that this UNESCO World Heritage site continues to thrive amidst modern pressures.
