A closer look
Aztec capital was not just a city; it was a floating farm engineered for survival. In the shallow lakes around Tenochtitlan, farmers built chinampas, artificial islands woven from reeds, mud, and roots, creating a grid of fertile plots separated by canals. These gardens produced multiple harvests a year of maize, beans, and vegetables, feeding hundreds of thousands of people with almost zero imported food. Waste from the city fertilized the soil, and the water acted as natural frost protection. When the Spanish conquered the region, they drained much of the lake and dismantled the system, replacing it with European style agriculture and dry land building. Centuries later, modern cities struggle with food security and flooding in the exact same basin. The lost blueprint for sustainable urban farming was there long before we invented the term.
