Members of the Hopi and Zuni tribes are working alongside archaeologists within the Bears Ears National Monument to preserve masonry structures built by their ancestors hundreds of years ago. Uniquely, they are using methods and materials that reflect traditional perspectives about these places.

The space beneath solar panels is often thought to be bare, wasted ground. But what if it could be used to grow crops and graze livestock? That’s the idea behind agrivoltaics.

No creature conjures up images of the burning hot desert better than the rattlesnake, with its venomous fangs, buzzing tail and ability to withstand extreme heat. But even rattlesnakes get thirsty, and they know an unusual way to quench their thirst: they harvest rainwater from their backs.

Pinyon jays are sky blue birds that live in large flocks in the pinyon-juniper woodlands of the Colorado Plateau. They are not officially endangered, but their populations have plummeted in the last half-century. The Audubon Society has found an unusual way to raise awareness about their plight: specialty brews from the Drinking Horn Meadery in Arizona, and the Bosque Brewing Company in New Mexico.

Four decades ago, naturalist and author Gary Paul Nabhan wrote a book called The Desert Smells Like Rain. The title came from the answer a young Tohono O’odham boy gave when asked what the desert smelled like to him.

Astrobiologist Daniel Apai turns to the natural world for solutions to climate change. Lately, he’s been investigating one of Earth’s most basic lifeforms—abundant ocean-dwelling algae called coccolithophores.

The coronavirus pandemic has worsened food access because of job loss and supply chain issues. More than two million Arizonans faced food insecurity last year, including many working poor who struggle to make ends meet, or those who live on tribal nations.
