Which best explains the successful development of agriculture in the desert climate of the American Southwest by American Indian
cultures such as the Pima, Hopi, and Hohokam? ' a) People of the Southwest were instructed in cultivating drought-tolerant crops by traders from civilizations in present-day Mexico. b) People of the Southwest developed systems of canals to divert water from nearby rivers to irrigate their crops. c) People of the Southwest developed a seasonal calendar that allowed them to predict the best times of year to plant and harvest. d) People of the Southwest primarily cultivated drought-resistant grasses for animal feed and subsisted on meat from livestock.
The successful development of agriculture in the desert climate by the Pima, Hopi, and Hohokam of the American Southwest is best described by formation of canals system by Southwest people that divert water from nearby rivers to irrigate their crops.
Agricultural engineering is one the biggest achievement for the people of the Southwest and they developed the first irrigation canal in the Gila River valley that directs water from rivers to fields. The canals are then modified and made narrower and deeper that minimize water loss through ground evaporation and absorption.
