“Nobody wants to go to the middle of the desert to figure out what soils are.” So Mahowald has been collaborating with NASA on the Earth Surface Mineral Dust Source Investigation mission, or EMIT, which launches to the International Space Station next month.
Eighty-five miles from the small town of Moab, Utah, located on the Colorado Plateau in the southwest of the US, soil ecologist Rebecca Finger-Higgens is hopscotching on copper-toned sandstone to avoid stepping on the desert’s black, burnt-looking crust of soil.
However, halfway through the event, all three cars are still in the running, and the team has even picked up a win in the 636 km third stage with rally veteran Carlos Sainz driving, at the age of 59.
The sparse rainfall and low water levels are one reason that state officials in June built a $10 million emergency project—the size of San Francisco’s Transamerica Pyramid laid on its side—to keep ocean saltwater from surging into the delta.
Burkes was at Burning Man, the conflagrant annual confab in Nevada’s Black Rock Desert.As early as that first year “on the playa”—Burner-speak for Black Rock—the Dune obsessives in the crew suggested everyone build mock stillsuits, a reference to the form-fitting bodywear that recycles precious fluids and keeps Arrakis’ desert-dwelling Fremen alive when they venture beyond the safety of their mountain villages, known as sietches.
Kort read the book during moments of downtime over the next weeks, as he led his platoon of 15 soldiers and four tanks through the Kuwaiti desert, and later when they took up residence in a powerless, abandoned building in Baghdad.

The garden is the latest iteration of the project known as the Great Green Wall, first envisioned as a viridescent belt squiggling thousands of miles across the Sahel region, from Senegal to Djibouti.“When the government plants trees, it’s the community people who will sustain them” Okolie says.
A decade-long effort by 150 scientists has mapped microhabitats like this across the United States, using such data to identify the most resilient landscapes in the face of climate change.

AmeriCorp stewardship assistant Brittney Cade (front) leads a team of volunteers in planting trees along the Amargosa River.Planting 100,000 trees – and helping birds adapt to climate change – is just the latest chapter in the rich conservation history of the Amargosa.
It’s the worst Saharan dust event the island has seen in 15, maybe 20 years, says Olga Mayol-Bracero, an atmospheric chemist at the University of Puerto Rico.
Now all the freight cars were filled to the top with sooty iron ore, giving Guerin no choice but to climb on top for the ride home.
Around 20 species of the 7,000 known grasshopper varieties transform into what’s known as a gregarious phenotype, which means their bodies actually change as they socialize into swarms.But why does the desert locust go gregarious, when the vast majority of grasshopper species remain solitarious?
Gross says such efficiency can deliver heat 20 percent more cheaply than fossil fuels can.Gross is also building a receiver that can handle temperatures above 2,700 degrees.
"It was promoted as this extravagant development, but in many ways it failed spectacularly," says Chicago-based photographer Noritaka Minami, who first learned about California City while attending graduate school at UC Irvine.
17 June 2019, Rome - Unlocking the potential of agricultural innovations, be it simple solutions or satellite-based technologies, will help prevent a drought from turning into famine and forced displacement and to reverse desertification, FAO Director-General José Graziano da Silva said today.
Images in the project span portraiture, reportage, and action photos, some of which were shot from the sweltering cabin of a drifting car. In time, then, Young's photos might join Higley's poem as dedications to bygone eras.
A 6-Legged Robot Stares at the Sky to Navigate Like a Desert Ant Dupeyroux et al., Sci. Robot. 4, eaau0307 (2019) Sensing polarized light is an indispensable skill for the ants, and perhaps soon it will also serve robots and autonomous cars.
And that’s why it was a bit jarring to read about a leading wildlife conservationist and wilderness advocate feeding grizzly bears. These bears are largely found in the Great Gobi A Strictly Protected Area, a wilderness region five times larger than Yellowstone National Park.
Brave in the face of these field challenges, conservation biologists commonly embark on biological assessments to take the pulse of an ecosystem or monitor for the presence of rare or invasive species.
“If the screwbean mesquite disappears, it will be a huge loss for migrating and desert riparian birds,” says Warren. “Experts have pointed out that screwbean mesquites are dying in many places where there has been no tamarisk control,” says Warren.
But this study is among the first to model how wind and solar farms would affect the Sahara, all while considering how growing green plants and trees would respond to these changes, said Li, who started the study while a postdoctoral researcher in the Department of Atmospheric and Oceanic Science at the University of Maryland.
