Clamshell containers on supermarket shelves in the United States may depict verdant fields, tangles of vines and ruby red tomatoes. But at this time of year, the tomatoes, peppers and basil certified as organic by the Agriculture Department often hail from the Mexican desert, and are nurtured with intensive irrigation.
Growers here on the Baja Peninsula, the epicenter of Mexico’s thriving new organic export sector, describe their toil amid the cactuses as “planting the beach.”
Del Cabo Cooperative, a supplier here for Trader Joe’s and Fairway, is sending more than seven and a half tons of tomatoes and basil every day to the United States by truck and plane to sate the American demand for organic produce year-round.
But even as more Americans buy foods with the organic label, the products are increasingly removed from the traditional organic ideal: produce that is not only free of chemicals and pesticides but also grown locally on small farms in a way that protects the environment.
The explosive growth in the commercial cultivation of organic tomatoes here, for example, is putting stress on the water table. In some areas, wells have run dry this year, meaning that small subsistence farmers cannot grow crops. And the organic tomatoes end up in an energy-intensive global distribution chain that takes them as far as New York and Dubai, United Arab Emirates, producing significant emissions that contribute to global warming.
From now until spring, farms from Mexico to Chile to Argentina that grow organic food for the United States market are enjoying their busiest season.
“People are now buying from a global commodity market, and they have to be skeptical even when the label says ‘organic’ — that doesn’t tell people all they need to know,” said Frederick L. Kirschenmann, a distinguished fellow at the Leopold Center for Sustainable Agriculture at Iowa State University. He said some large farms that have qualified as organic employed environmentally damaging practices, like planting only one crop, which is bad for soil health, or overtaxing local freshwater supplies.
Many growers and even environmental groups in Mexico defend the export-driven organic farming, even as they acknowledge that more than a third of the aquifers in southern Baja are categorized as overexploited by the Mexican water authority. With sophisticated irrigation systems and shade houses, they say, farmers are becoming more skilled at conserving water. They are focusing new farms in “microclimates” near underexploited aquifers, such as in the shadow of a mountain, said Fernando Frías, a water specialist with the environmental group Pronatura Noroeste.
They also point out that the organic business has transformed what was once a poor area of subsistence farms and where even the low-paying jobs in the tourist hotels and restaurants in nearby Cabo San Lucas have become scarcer during the recession.
To carry the Agriculture Department’s organic label on their produce, farms in the United States and abroad must comply with a long list of standards that prohibit the use of synthetic fertilizers, hormones and pesticides, for example. But the checklist makes few specific demands for what would broadly be called environmental sustainability, even though the 1990 law that created the standards was intended to promote ecological balance and biodiversity as well as soil and water health.
Experts agree that in general organic farms tend to be less damaging to the environment than conventional farms. In the past, however, “organic agriculture used to be sustainable agriculture, but now that is not always the case,” said Michael Bomford, a scientist at Kentucky State University who specializes in sustainable agriculture. He added that intense organic agriculture had also put stress on aquifers in California.
Some organic standard setters are beginning to refine their criteria so that organic products better match their natural ideals. Krav, a major Swedish organic certification program, allows produce grown in greenhouses to carry its “organic” label only if the buildings use at least 80 percent renewable fuel, for example. And last year the Agriculture Department’s National Organic Standards Board revised its rules to require that for an “organic milk” label, cows had to be at least partly fed by grazing in open pastures rather than standing full time in feedlots.
But each decision to narrow the definition of “organic” involves an inevitable tug-of-war among farmers, food producers, supermarkets and environmentalists. While the United States’ regulations for organic certification require that growers use practices that protect water resources, it is hard to define a specific sustainable level of water use for a single farm “because aquifer depletion is the result of many farmers’ overutilizing the resource,” said Miles McEvoy, head of the National Organic Program at the Agriculture Department.
While the original organic ideal was to eat only local, seasonal produce, shoppers who buy their organics at supermarkets, from Whole Foods to Walmart, expect to find tomatoes in December and are very sensitive to price. Both factors stoke the demand for imports. Few areas in the United States can farm organic produce in the winter without resorting to energy-guzzling hothouses. In addition, American labor costs are high. Day laborers who come to pick tomatoes in this part of Baja make about $10 a day, nearly twice the local minimum wage. Tomato pickers in Florida may earn $80 a day in high season.
Manuel Verdugo, 42, began organic tomato farming on desert land in San José del Cabo five years ago and now owns 30 acres in several locations. Each week he sends two and a half tons of cherry, plum and beefsteak tomatoes to the United States under the brand name Tiky Cabo.
He has invested in irrigation systems that drip water directly onto plants’ roots rather than channeling it through open canals. He is building large shade houses that cover his crops to keep out pests and minimize evaporation. Even so, he cannot farm 10 acres in the nearby hamlet of La Cuenca because the wells there are dry.
At another five-year-old organic farm, Rosario Castillo says he can cultivate only 19 acres of the 100 he has earmarked for organic production, although he dug a well seven months ago to gain better access to the aquifer. The authorities ration pumping and have not granted him permission to clear native cactuses. “We have very little water here, and you have to go through a lot of bureaucracy to get it,” Mr. Castillo said.
Many growers blame tourist development — hotels and golf courses — for the water scarcity, and this has been a major problem in coastal areas. But farming can also be a significant drain. According to one study in an area of northern Baja called Ojos Negros, a boom in the planting of green onions for export a decade ago lowered the water table by about 16 inches a year. “They were pumping a lot of groundwater, and that was making some people rich on both sides of the border at the expense of the environment,” said Victor Miguel Ponce, a professor of hydrology at San Diego State University.
The logistics of getting water and transporting large volumes of perishable produce favors bigger producers. Some of the largest are American-owned, like Sueño Tropical, a vast farm with rows of shade houses lined up in the desert that caters exclusively to the American market.
While traditional organic farmers saw a blemish or odd shape simply as nature’s variations, workers at Sueño Tropical are instructed to cull tomatoes that do not meet the uniform shape, size and cosmetic requirement of clients like Whole Foods. Those “seconds” are sold locally.
Yet the connection to the United States has brought other kinds of benefits. Del Cabo Cooperative, which serves as a broker for hundreds of local farmers, provides seeds for its Mexican growers and hires roving agronomists and entomologists to assist them in tending their crops without chemicals. As the American market expands, said John Graham, a coordinator of operations at Del Cabo, he is always looking to bring new growers into his network — especially those whose farms draw on distant aquifers where water is still abundant.

Posted by: Farmer on Jan 1, 2012 at 02:58 PM Natural pesticides To me seems like an oxymoron. Just because somthing shows up in nature does not mean it is any safer than man made pesticides. The poisin is in the dose not the compound used. No matter the compound toxic levels are used to control the pests. The environment then breaks the compounds down to non lethal levels. Just because a pesticide is natural does not make it any less dangerous. Posted by: Shine Location: NE NC on Jan 1, 2012 at 11:44 AM Just to clue you in after my reply on the post. My Father was the President of the North Carolina Agribusness Council. He and the late Jim Graham opted to design a produce marketing facility that would have been in Pasquotank Co. Politics kept it buffered for the simple reason they did not want the competion.The Commisioner Jim – long time friend was the sole supporter. The Cartel and Politics hung the idea out to dry. Posted by: Shine on Jan 1, 2012 at 11:21 AM "Organic before the 50′s" Do yo know what DDT, malathyon, Agent Orange which is nothing but a rich defoliant that also has carcinoginc properties. I am not ignorant — I have been in this field along time before alot was known about organic anything.
