Indigenous peoples have known for millennia to plant under the shade of the mesquite and paloverde trees that mark the Sonoran Desert here, shielding their crops from the intense sun and reducing the amount of water needed.
The modern-day version of this can be seen in the Santa Catalina Mountains north of Tucson, where a canopy of elevated solar panels helps to protect rows of squash, tomatoes and onions. Even on a November afternoon, with the temperature climbing into the 80s, the air under the panels stays comfortably cool.
Such adaptation is central to the research underway at Biosphere 2, a unique center affiliated with the University of Arizona that’s part of a movement aimed at reimagining and remaking agriculture in a warming world. In the Southwest, projects are looking to plants and farming practices that Native Americans have long used as potential solutions to growing worries over future food supplies. At the same time, they are seeking to build energy resilience.
