Rows of green lettuce in a fieldHow might climate change affect Arizona? A decrease in crop yields, for one thing, according to Andrew Berardy – a postdoctoral research associate with the Food Systems Transformation Initiative – and Senior Sustainability Scientist Mikhail Chester.

After studying the food-energy-water nexus that governs agriculture in Arizona, the pair found that the state's yields could drop more than 12 percent per 1 degree Celsius. This would have cascading effects – including more irrigation and increased food prices – that would be felt throughout the region.

In light of roll-backs in environmental protection by the Trump administration, Berardy and Chester advise that farmers upgrade to more efficient irrigation methods like drip irrigation. Their findings were published in IOP Science.
