The Incas developed an effective irrigation system by constructing canals, terraces, and reservoirs to divert water from rivers and store it for agricultural use. These irrigation techniques allowed them to grow crops in the mountainous terrains of the Andes and sustain their empire’s agricultural needs.
So let us take a closer look at the inquiry
The Incas, an ancient civilization that thrived in the Andes region of South America, implemented a remarkable irrigation system to supply water to their crops. Their agricultural practices were crucial for sustaining their empire’s agricultural needs in the mountainous terrains of the Andes. Through the construction of canals, terraces, and reservoirs, they expertly diverted water from rivers and stored it for agricultural use.
Here are some intriguing details about how the Incas irrigated their crops:
Terraces: The Incas used terracing to create flat platforms on the slopes of mountains. These terraces prevented soil erosion and allowed water to flow evenly across the farmland. The flat surfaces also maximized land utilization.
Canals: The Incas engineered an extensive network of canals to transport water to various agricultural areas. These canals were engineered with precision, taking into account the natural slopes of the land and using gravity to ensure a steady flow of water.
Aqueducts: To overcome obstacles such as gorges or uneven terrain, the Incas constructed aqueducts. These impressive structures carried water across difficult landscapes, allowing it to reach fields situated at different elevations. This enabled the cultivation of crops in otherwise inaccessible locations.
Reservoirs: The Incas built reservoirs, known as puquios, to store water for later use during dry seasons or droughts. These storage systems were crucial in ensuring a consistent water supply for agriculture. They were often strategically placed to capture water from underground springs or mountain runoff.
Sustainable practices: The Incas implemented sustainable practices to preserve and manage their water resources effectively. They regulated water usage, allocating it based on the specific needs of different crops and agricultural areas. This careful management helped prevent water scarcity and maintain the productivity of their lands.
To illustrate the significance of the Incas’ irrigation system, the famous explorer and archaeologist Hiram Bingham once remarked, “The agriculture of the Incas far surpassed in excellence and variety that of any other people in the world.”

By employing these sophisticated irrigation techniques, the Incas were able to overcome the challenging landscapes of the Andes and successfully cultivate crops to meet their empire’s agricultural needs. Their mastery of irrigation played a vital role in the development and sustainability of their civilization.
See a video about the subject
This YouTube video titled “Inca Terraces (Passport to Peru Highlights)” explores the innovative agricultural techniques of the Inca civilization, focusing on the terraces called Andenes. These terraces, carved into the mountainsides, allowed the Inca to grow crops in otherwise inhospitable regions. The engineering of these terraces included good drainage and fertile soil, maximizing productivity. The video also highlights the Inca’s practice of cultivating different crops at different elevations, known as vertical archipelago, to ensure food security. Additionally, it mentions the Inca’s sustainable practices, including the strategic placement of large storehouses throughout the empire to store surpluses of food and resources.

They built cisterns and irrigation canals that snaked and angled down and around the mountains. And they cut terraces into the hillsides, progressively steeper, from the valleys up the slopes.
