The agricultural practices of the Native Americans inhabiting the American Southwest, which includes the states of Arizona and New Mexico plus portions of surrounding states and neighboring Mexico, are influenced by the low levels of precipitation in the region. Irrigation and several techniques of water harvesting and conservation were essential for successful agriculture. To take advantage of limited water, the southwestern Native Americans utilized irrigation canals, terraces (trincheras), rock mulches, and floodplain cultivation. Success in agriculture enabled some Native Americans to live in communities which numbered in the thousands as compared to their former lives as hunter-gatherers in which their bands numbered only a few dozen.

Hohokam was a culture in the North American Southwest in what is now part of south-central Arizona, United States, and Sonora, Mexico. It existed between 300 and 1500 CE, with cultural precursors possibly as early as 300 BCE. Archaeologists disagree about whether communities that practiced the culture were related or politically united. According to local oral tradition, Hohokam societies may be the ancestors of the historic Akimel and Tohono Oʼodham in Southern Arizona.
