Air Quality Worsens as Drought Forces California Growers to Burn Abandoned Crops
15th June 2022
With periods of extended dryness and water curtailments occurring more frequently due to climate change, growers in California’s Central Valley — one of the most productive agricultural regions on the planet — are increasingly looking to fallow fields or uproot orchards and vineyards for lack of irrigation. Once gathered into towering pyres, the vegetation is then set ablaze, sending lung- and heart-aggravating haze across the valley.
San Joaquin Valley air regulators have struggled for nearly 20 years to outlaw the practice of agricultural burning, encouraging farmers instead to grind up forsaken crops in wood chippers and spread them as mulch. But amid a third year of drought, some fear a resurgence in large-scale burning because it’s cheaper than grinding, and because so many acres are being abandoned due to drought.
Already, 395,000 acres of farmland have been fallowed across California because of the drought, according to UC Merced research. Industry groups estimate 60,000 acres of almond trees and 15,000 acres of vineyards will be removed statewide this year as well.
“If you’re not able to get water, then you’re gonna have a lot of dry stuff that’s potentially going to die. And then what’s gonna happen with that waste?” asked Catherine Garoupa White, executive director of the Central Valley Air Quality Coalition. “It’s easier to just strike a match and light it on fire.”
