- Inca terrace farming: The Incas built terraces on the sides of mountains to create flat land for farming. This allowed them to grow crops in areas that would otherwise be too steep for cultivation. The terraces also helped to prevent soil erosion and water loss.
- Aztec floating gardens: The Aztecs built floating gardens on the surface of lakes and rivers. These gardens were made from layers of泥土, reeds, and other organic materials. The roots of the plants grew down into the water, and the plants were able to absorb all the nutrients they needed. Floating gardens were a sustainable way to grow crops in areas with limited land.
Both Inca terrace farming and Aztec floating gardens are examples of how indigenous people developed sustainable ways to grow food. These methods are still used today by farmers around the world.
