Because they allowed growth (through the use of excess moisture not natural to the native environment) where, historically, growth could not have happened without human intervention. Areas that had low moisture levels and couldn't be used for growing crops, were (and are) now able to grow crops.
Irrigation systems would be particularly important for early North Americans in arid regions such as the Southwest, where water availability is limited. Building irrigation systems would have enabled them to support agricultural practices and sustain communities in these dry environments.
Irrigation helped early farmers by providing a consistent water supply to their crops, enabling them to grow food in regions with limited rainfall. This increased agricultural productivity, allowing for larger and more reliable harvests. Additionally, irrigation systems allowed farmers to cultivate crops throughout the year, rather than just during the rainy season.
Early farmers controlled water supplies by building irrigation systems such as canals, ditches, and reservoirs to divert and store water for their crops. They also utilized natural features like rivers, streams, and wetlands to manage water flow. Additionally, they may have employed techniques such as terracing to control soil erosion and maximize water retention in their fields.
The early farmers of the plains faced challenges such as unpredictable weather conditions, including droughts and floods, limited access to water for irrigation, and the presence of pests and diseases that affected their crops. Additionally, the lack of modern farming technology made it hard for them to efficiently cultivate and harvest their crops.
River valleys were the most important physical map feature for early civilizations because they provided access to water for drinking, irrigation, and transportation. Rivers like the Nile, Tigris, and Euphrates were essential for the development of agriculture and trade, leading to the growth of early civilizations.

Flooding was an extreme problem with the early farmers. The two inventions that helped them deal with the flooding problem were seed plows and irrigation systems.

By trapping water in dams and weirs, and leading irrigation channels through the fields.
Irrigation systems date back thousands of years, with evidence of their use in ancient civilizations such as Mesopotamia, Egypt, and the Indus Valley around 6,000 to 7,000 years ago. These early systems were developed to enhance agricultural productivity by controlling water supply to crops. Over time, irrigation techniques evolved, leading to the sophisticated systems we see today. Thus, irrigation systems are among the oldest agricultural practices in human history.
Early Native American farmers used their agricultural techniques to domesticate corn. Despite this, their farms were generally unproductive and they relied heavily on hunting and gathering.
