“Basket of reeds” is what the Náhuatl word ‘chinampan’ means. Here at Agroecología, we delve into the fascinating world of chinampas. These are the ingenious pre-Hispanic cropping systems of Xochimilco. Xochimilco lies to the south of Mexico City.
Imagine Mexico City surrounded by a lake. The Aztec city was built on islands. This water provided protection from invaders. Soil was scarce in the volcanic landscape. The population needed food. Prehispanic farmers devised a plan. They built soil and beds to plant on the lake. They wove reeds and aquatic plants into baskets. Organic matter accumulated in these baskets. As the organic matter decomposed, corn, beans, and squash were planted. Farmers constantly renovated these beds with mud. This mud was from below the beds.
Today, these beds no longer float. Canals separate plots of land. Boats provide the only access. Industrial agriculture has changed the traditional cropping system. Now, it’s attractive as a tourist destination.
Despite urbanization, Xochimilco remains the lungs of Mexico City. It helps maintain a mild climate. But chemical fertilizers and water contamination threaten this system. Urban waste is dumped into the canals. This damages the ingenious agricultural system. It fed Mexico City for thousands of years.
Most chinampas now serve as getaways. People rent them for parties. Some are used for industrial flower production. This is especially for Day of the Dead and Christmas. Pesticides and fertilizers pollute the canals. The mud used to replenish the soil becomes contaminated.
However, some ‘chinamperos’ are reviving the chinampas. Felipe grew up on his family’s chinampa. He learned traditional farming from older farmers. Felipe and his neighbors are recovering traditional varieties. These include beans that climb trees. Also, there are perennial cherry tomatoes and purple maize.
Water quality is a major concern. Felipe blocked off a secondary canal. He dredged the canal by hand. He planted species for water filtration. Now, his canal has clean water and diverse life.
Can we measure the value of a lettuce that balances the ecosystem? It’s priceless. Urbanization threatens the chinampas. Many animal and plant species depend on these green spaces. Xochimilco regulates Mexico City’s temperature. Losing it could have unpredictable consequences.
‘Chinamperos’ are spreading awareness. They teach visitors about soil and water renovation. This raises awareness about the city’s dependence on Xochimilco. It conveys messages about eco-dependency.
Consumers can support agroecology by buying directly from producers. Farmers’ markets connect consumers and producers. These initiatives help continue agroecological practices.
Mexico’s policies are incorporating social and political aspects of agroecology. New programs train producers and technicians. They develop learning communities and cooperatives. These programs also focus on food sovereignty research. A museum will honor maize as part of Mexican history.
Challenges remain in Xochimilco. These challenges include managing urban growth and water contamination. But chinamperos like Felipe provide hope. His eyes sparkle when he talks about the life returning to his canal. Remember Felipe’s work as you explore Agroecología. Consider the importance of protecting this vital ecosystem.
