How did the Inca build terraced fields on steep mountain slopes?

The Inca civilization employed advanced agricultural techniques to adapt to their mountainous environment. They created terraced fields by leveling and reinforcing steep slopes with stone retaining walls. These terraces prevented soil erosion and allowed for efficient water management. The Incas used a system of channels and aqueducts to direct and distribute water to the terraces, ensuring that crops received adequate irrigation. Additionally, they incorporated drainage systems to handle excess water and prevent waterlogging. This terracing not only increased the amount of usable farmland but also improved soil fertility and productivity. The integration of these methods into their agricultural practices supported a thriving empire despite challenging geographic conditions.
