The National Resources Defense Council (NRDC) launched a web tool last week that lets users see how their state is being impacted by climate change. NRDC’s tool shows that climate change will only worsen the air pollution in the San Joaquin Valley of California.
As the agricultural center of the world, it is rather scary to think that a polluted region is supplying the nation with produce, meat, dairy and cotton. If you doubt that the San Joaquin Valley supplies a good deal of the nation’s food, go to your local grocery store. Head to the produce section, and look at the boxes that hold the fruits and vegetables. Much of it will have California stamped somewhere on the box, and the chances are great it came from the Valley.
If you have ever eaten raisins, then you have a link to the San Joaquin Valley. Almost all of the raisins in the U.S. (99.5 percent) are produced within a 100 mile radius of Fresno, smack dab in the middle of the Valley. About 40 percent of the world’s raisins come from the Fresno area.
California ranks number one in the U.S. for cheese production, and much of the cheese is made in the San Joaquin Valley. California also ranks number one in the U.S. for cotton production, and almost all of the cotton is produced in the San Joaquin Valley.

How bad is pollution in the Valley? The Valley has one of the worst air basins in the country, along with Los Angeles, as the American Lung Association’s (ALA) State of the Air 2011 report shows. Bakersfield, a city in the Southern San Joaquin Valley, ranks number two in all three State of the Air 2011 categories: ozone, year-round particle pollution and short term particle pollution. Other major Valley cities and counties are on all three lists.
Six Valley cities are listed among 25 of the worst cities for ozone pollution and seven out of the Valley’s eight counties are listed among the 25 worst counties for ozone. All but one of the Valley’s counties are listed for short-term particle pollution and five Valley cities are listed among the worst 24 cities for year-round particle pollution, as are the majority of its counties.
What are the sources of the Valley’s pollution? A 2004 report by the Union of Concerned Scientists (UCS) lists agriculture (including agricultural burning) and heavy duty diesel trucks and buses as sources of pollution. Highway 99 runs through the Valley and is a major corridor in the state for transporting goods. Agricultural burning (such as burning the grape trays that grapes dry on to become raisins) is still an all-too-common practice in the Valley. It must be added, though, that a viable (cost effective) alternative to agricultural burning has not been created for farmers, and the majority of the Valley’s farms are family owned. Farmers are just trying to survive.
