YUMA, Arizona (AP) — On a dirt road past rows of date trees, just feet from a dry section of Colorado River, a small construction crew is putting up a towering border wall that the government hopes will reduce — for good — the flow of immigrants who cross the United States (US)-Mexico border illegally.
Cicadas buzz and heavy equipment rumbles and beeps before it lowers nine-metres-tall sections of fence into the dirt. “Ahí está!” — “There it is!” — a Spanish-speaking member of the crew said as the men straighten the sections into the ground. Nearby, workers pull dates from palm trees, not far from the cotton fields that cars pass on the drive to the border.
South of Yuma, Arizona, the tall brown bollards rising against a cloudless desert sky will replace much shorter barriers that are meant to keep out cars, but not people.
This eight-kilometre section of fencing is where US President Donald Trump’s most salient campaign promise — to build a wall along the entire southern border — is taking shape.
The president and his administration said this week that they plan on building between 724 and 806 kilometres of fencing along the nearly 3,218-kilometre border by the end of 2020, an ambitious undertaking funded by billions of defence dollars that had been earmarked for things like military base schools, target ranges and maintenance facilities.
Two other Pentagon-funded construction projects in New Mexico and Arizona are underway, but some are sceptical that so many miles of wall can be built in such a short amount of time. The government is up against last-minute construction hiccups, funding issues and legal challenges from environmentalists and property owners whose land sits on the border.
The Trump administration said the wall — along with more surveillance technology, agents and lighting — is key to keeping out people who cross illegally. Critics say a wall is useless when most of those apprehended turn themselves in to Border Patrol agents in the hope they can be eventually released while their cases play out in immigration court.
In Yuma, the defence-funded section of tall fencing is replacing shorter barriers that US officials say are less efficient. It comes amid a steep increase since last year in the number of migrant families who cross the border illegally in the Yuma area, often turning themselves in to Border Patrol agents. Many are fleeing extreme poverty and violence, and some are seeking asylum.
So far this year, Border Patrol agents in the Yuma sector have apprehended over 51,000 family units. That’s compared with just over 14,500 the year before — about a 250 per cent increase.
The Yuma sector is the third busiest along the southern border, with officials building a temporary, 500-person tent facility in the parking lot of the Border Patrol’s Yuma headquarters in June. It spent just under USD15 million for the setup and services for four months, including meals, laundry and security, but officials are evaluating whether to keep it running past next month as the number of arrivals in Yuma and across the southern border have fallen sharply in recent months.
The drop is largely due to the Mexican government’s efforts to stop migrants from heading north after Trump threatened tariffs earlier this year to force Mexico to act.
The number of people apprehended along the southern border fell by 61 per cent between this year’s high point in May and the end of August. In Yuma, it fell by 86 per cent, according to government figures. Most people apprehended are either travelling as families or are unaccompanied children.
“Historically this has been a huge crossing point for both vehicles as well as family units and unaccompanied alien children during the crisis that we’ve seen in the past couple of months,” Border Patrol spokesman Jose Garibay said. “They’ve just been pouring over the border due to the fact that we’ve only ever had vehicle bollards and barriers that by design only stop vehicles.”
Victor Manjarrez Jr, a former Border Patrol chief who’s now a professor at the University of Texas, El Paso, was an agent when the government put up the first stretch of barriers along the southern border — in San Diego.
He’s seen barriers evolve from easily collapsible landing mats installed by agents and the National Guard to the sophisticated, multibillion-dollar projects now being done by private contractors. Manjarrez said tall border fencing is crucial in some areas and less helpful in others, like remote stretches of desert where shorter barriers and more technology like ground sensors would suffice.
“One form doesn’t fit in all areas, and so the fence itself is not the one solution. It’s a combination of many things,” Manjarrez said.
The ease of construction varies by place and depends on things like water, Manjarrez said, adding that just because a plot of land is flat “doesn’t mean it’s not complex”.
He said building 724 and 806 kilometres of fence by the end of next year would be tough if that figure doesn’t include sections of the wall that have been built recently.
“As it stands now, contractors are building pretty fast,” Manjarrez said. The real question is whether the government needs to build that much fencing, he said.
The Trump administration may face those issues along with lawsuits from landowners who aren’t giving up their property so easily and environmentalists who say the barriers stop animals from migrating and can cut off water resources.
