Irrigated farming is most suitable in the Great Basin due to the region's dry climate and limited rainfall.

The Great Basin has an arid climate with very little rainfall, making traditional rain-fed farming challenging. Therefore, irrigated farming is the most viable option for growing crops in the region. Irrigation systems are used to bring water to crops, primarily from snowmelt or groundwater. This enables the cultivation of crops such as alfalfa, wheat, and barley, which can be grown in the region with sufficient water. Extensive livestock farming, such as raising cattle and sheep, is also common in the Great Basin, but irrigated farming plays a critical role in the area's agricultural practices.
