Sonoran Desert
According to one archaeologist the Ancestral People of the Sonora Desert were the “First Masters of the American Desert.” I like that term. It gives them the respect they deserve. They did in fact learn to live and even thrive in the harsh conditions of the Sonoran Desert for more than a thousand years. They built brush-covered houses in pits that at first were loosely arranged. Later they built more organized villages around courtyards.
The Ancestral people of the Sonoran Desert (formerly called Hohokam) learned to live in harmony with the desert. They harvested the plants and animals of the Sonoran Desert, including saguaro fruit, mesquite beans, mule deer, rabbits, turtles and fish among others.
The climate in the region was hot and dry with very few all-year water sources and very sparse rainfall, and therefore provided very challenging conditions for permanent settlement. That was a challenge that the Ancestral people of the Sonoran Desert were up for during their 1,000 years of occupation here. They were darn good farmers. They grew crops that could withstand the harsh conditions. That included crops such as corn that matured fast enough that the plants were not exposed to the elements for too long. Some of their crops could be grown twice per year. They also planted beans, squash, tobacco, cotton, and agave. In their fields they also encouraged the growth of several local wild plants such as amaranth.
Interestingly, the main cause of death of the Ancestral people of the Sonoran Desert was tooth decay. They chewed corn and the sweetness caused tooth decay that led to many deaths.
In addition to farming, the Ancestral People also gathered food, medicine, and building materials from the surrounding wilderness. They collected wood, fruit, buds, and seed from plants such as Palo Verde, mesquite, ocotillo, ironwood, creosote, Bursage, and saltbush among others. They even ate saguaro, cholla, hedgehog, and prickly pear cactus.
The Ancestral people of the Sonoran Desert culture is thought to have begun at about 300 BCE (Before Common Era) to 300 CE (Common Era). During this period of time, the Ancestral people of the Sonoran Desert began local agriculture and it is for this that they became most famous–justifiably famous I might add. They established villages with pit houses, storage pits, grading tools, baskets, and pottery. They also drew from the Mesoamerican civilization. It is fairly clear that by about 300 CE in Arizona the Ancestral People lived in permanent settlements along the Salt and Gila Rivers both of which ran permanently during this time before dam construction.
Ancestral farmers saw water as their most precious resource. It was sacred to the Ancestral farmers of the Sonoran Desert and facilitated the diversity of their crops. Modern farmers plant monocultural crops. Ancestral farmers often planted what they called “The Three Sisters” on one hill. That meant that they planted corn, beans, and squash. Each crop helped the others by providing shade, shelter, or nutrients. The earliest plants then provided shade for late comers, thus improving productivity. They did not believe in tilling the soil to remove competition. They expected their crops to cooperate with each other. A modern Canadian scientist, Suzanne Simard, has tried to make this important point about the ecosystem of the subtropical rainforest in British Columbia. Plants do compete with each other, but they do much more than that. They actually help each other too. North American foresters had a difficult time understanding this. They assumed trees only competed with each other. She proved they also cooperated with each and even in some cases helped non-kin. The ancestral people of the Sonoran desert understood this 2,000 years ago.
Ancestral farmers concentrated on conserving water. They were not labour efficient, because to them labor was cheap. Water was expensive. As a result, they were very efficient with water, their most critical resource.
Modern farmers employ elaborate modern equipment that mechanizes the work and conserves human energy, thus conserving or minimizing their primary resource. They use huge water systems to bring in massive amounts of water to the desert. As a result, they are inefficient with water and very efficient with human labor. Modern farmers could learn a lot from ancestral farmers and vice versa.
