South of the border, fence is no deterrent
Would-be migrants say nothing will stop them from working in US.

There has been a great deal of change in the Yuma sector since agent Mike Gramley came here 12 years ago with the border patrol. Back then, there were 300 agents who would follow footsteps in the dirt track roads, and a newly erected fence that ran for six miles around the urban areas - resulting in 50 apprehensions a day.Skip to next paragraph

The pace of change has been furious in the last year: the number of agents in Yuma has more than doubled to 650, and the existing fence is being elevated to 12 feet and extended to 10 miles. An all-purpose road is being paved, a secondary fence is going up, stadium lights shine spotlights throughout the night, motion sensors are buried in the ground, surveillance planes fly overhead, and high-resolution infrared cameras beam the slightest movement back to control rooms at headquarters.
Meanwhile, 6-1/2 feet tall vehicle barriers - made of galvanized steel and filled with a special resin that prevents them from being cut - are driven seven feet into the ground and four feet apart all the way to Cabeza Prieta, 125 miles along the border.
Apprehensions have soared. From October 1, 2004 through September 30, 2005, 138,460 individuals were caught illegally crossing the border in the Yuma sector.
But to what extent does this mean fewer illegal immigrants are actually getting across?
Proponents of a fence argue that these preventative measures can be effective, and point to the San Diego sector as proof. There, after the creation of a fence and a beefing up of enforcement around the point of entry in the early 1990s - part of Operation Gatekeeper - that sector saw the number of attempted crossings plummet. In 2005 126,910 illegal immigrants were apprehended in this sector, according to the border patrol, compared with a peak of 629,650 in 1986.
The problem with this, though, say critics, is that such measures only serve to push the human traffic elsewhere. Operation Gatekeeper did drastically cut down the number of illegal immigrants trying to cross near San Diego, but this only sent people to Texas. Beefed up patrols along the Texas border soon pushed the traffic away from El Paso and toward Nogales and Yuma. Today, close to half of all illegal crossings take place in Arizona.
But, with increased vigilance near entry points and urban areas in this state, illegal immigrants try crossing in more difficult terrain - in locations where temperatures during the summer months often rise into the hundreds and never drop.
A record 473 migrants died in 2005 while crossing the US-Mexico border, the most since the Border Patrol began tracking such deaths in 1999. Heat exhaustion accounted for 168 of the 473 migrant deaths, and 12 died of exposure to the cold. Oftentimes, victim's bodies go unidentified and relatives never know what happened to them.
"Our mission is to secure the border - it is certainly not our goal to push the migrants to cross in more dangerous areas," says Gramley. "But it is also clear that that is what is happening."
Also, by making the journey more difficult, the coyotes become more necessary, and can charge higher prices. This, in turn, affects how long migrants stay in the US as they work to pay back crossing fees. According to Mexico's National Population Council, illegal immigrants stayed in the US an average of about six months during 1993-97. Those stays had increased to more than a year by 2001-04.
Back in Altar, Dagoberto Martinez is standing on the side of the road looking south, toward home. He is 17 years old, and like the Ortiz brothers, from Hidalgo. It's his first time here, his first time away from his brothers, his first attempt at crossing a border. He is not scared, he says. But he looks scared.
He will go to Los Angeles. There is work there and a second cousin too. At home, he says simply, there was no work. He shifts his gaze. "That's my whole story," he says.
