California’s Farm Belt Didn’t Dodge the Summer Heat Wave

Abnormally warm summer temperatures were felt across much of interior California

Even tomatoes can only take so much heat. A belt from Bakersfield to the northern Sacramento Valley produces a third of the nation's canning tomatoes.

Autumn is here, so says the calendar. Living on the coast, it might be easy to think that California escaped the heat wave suffered by much of the nation this summer. While that may be true for most of the large coastal population centers, it was a different story for much of the state’s interior farm belt.

Throughout June and July, even Central Valley spots escaped much of the heat felt by the Great Plains, though Cal Expo officials blamed the heat, in part, for tamping down attendance at the state fair. Then things heated up quickly — especially in the Sacramento and San Joaquin Valleys — through August and into September.  Valley towns including Redding, Red Bluff, Sacramento, Merced, Madera, Fresno, and Bakersfield, have been on the order of three-to-five degrees above normal for the duration of August and September.

Heat and Harvest: Calif. Farms on a Climate Collision Course

The Midwestern corn belt isn’t the only place threatened by climate change

New pests, a shrinking water supply and rising temperatures will alter agriculture in California.

Tightening water supplies, encroaching pests and dwindling winter "chill hours," vital to many crops, are just some of the climate challenges facing California farmers.

Heat and Harvest, a new series from KQED Science and the Center for Investigative Reporting looks at the multiple climate challenges confronting California farmers. It’s no trivial matter. California’s Central Valley is widely known as “the nation’s salad bowl,” and there’s more than bragging rights at stake. Ag contributes more than $30 billion a year to the state’s economy.

Previously, Climate Watch has focused on efforts in the ag sector to conserve water or lower the carbon footprint. Some farmers are trying new technologies, others are experimenting with renewable energy. But meeting climate challenges on multiple fronts will, for some farmers and ranchers, be a matter of survival.

Here are links to some previous reporting from Climate Watch, from ag’s potential role in California’s emerging cap-and-trade program for carbon emissions, to innovation on the renewable energy front and new conflicts over land use. Continue reading
