During our Yuma Legislative Tour in December, we saw miles and miles of lettuce, cotton, broccoli, seed crops, and more. We got muddy and trudged around the Romaine lettuce fields with migrant workers, and we also toured a cotton gin. (More photos are here on my Facebook page.)
After our first day of touring Yuma’s agricultural areas, we heard multiple presentations at a hosted dinner paid for by different growing/ranching industry groups and served up by 4H and JTED youth. The presentation by Paul Brierley, director of the University of Arizona Center of Excellence for Desert Agriculture, stuck out in my mind. He talked about using engineering technology to help growers in the Yuma area. According to the UA website, “The [Center of Excellence for Desert Agriculture], based in Yuma, is a public-private partnership (PPP) between the college and the Arizona and California desert agriculture industry, dedicated to addressing ‘on-the-ground’ industry needs through collaboration and research.” The website continues on to say: “More than two dozen industry partners from Yuma and Salinas, California, have invested in the center, together committing more than $1.1 million over the next three years.”
Brierley is an affable engineer who grew up on a large farm. According to Bierley, the primary problem that industry partners wanted the PPP center to tackle was “productivity”*. He talked about different ways to boost productivity by using technology. For example, Brierley said that the date palms needed help with pollination. He showed a photo of a migrant worker pollinating date trees using a machine that looked like a leaf blower strapped on his back. This human-assisted pollination worked, but to improve productivity, the UA and Yuma growers began experimenting with drones. They found that drones to be more efficient pollinators than people. Technology to the rescue: mechanical birds. (For some jobs, this is the future: people being replaced by machines.)
Another problem area that had been identified as a hindrance to productivity was birds. Birds– and four-legged creatures like dogs and coyotes– poo in the lettuce fields and create unsanitary conditions. Remember the e. coli outbreaks related to fresh spinach? Several growers and lobbyists expressed grave concern over any future e. coli outbreaks due to contaminated fresh produce. Now the UA folks and the growers boast that there are no footprints in the Yuma fields– not a bird track or a canine track anywhere.
