How the Trump border wall sapped a desert oasis dry
Ancient springs might not survive unchecked construction during the pandemic.
After heavy construction last summer and fall, during which wildlife were cleared and a natural pond was diverted, the US-Mexico border wall now covers the entire southern edge of Organ Pipe Cactus National Monument in Arizona.
Amidst the towering saguaro and pronged organ pipe cacti of southern Arizona’s Sonoran Desert, a 30-foot-tall fence snakes through the vegetation, shadowed by a barren strip of land that’s been carved into the mountainsides. Despite the COVID-19 pandemic, there’s been a flurry of activity in these borderlands, particularly in the area’s Organ Pipe Cactus National Monument. In the last months of the Trump administration, a Customs and Border Protection (CBP) construction crew has been dynamiting and drilling their way through nature refuges and cultural relics to make room for the new border wall. A 30-mile-long spine of steel poles filled with concrete now chokes the monument’s southern edge. Mixing the raw materials for this structure requires a lot of water—some 84,000 gallons a day, by CBP’s own estimates—a dwindling resource that’s being siphoned from the already arid landscape.
The
450 miles of border wall in sections of California, Arizona, New Mexico, and Texas have already required more
than 971,000 tons of concrete, according to CBP. (About 10 percent of that called for new construction; the rest replaced existing structures.) The demand for water, alongside historic droughts in the West, has had a colossal impact on the surrounding ecology of largely public and tribal lands across the Southwest, which scientists and Indigenous communities fear may take years, if not decades, to reverse.
