Extreme weather spurred by climate change, including droughts and heavy rains, may increase the risk of nitrates from fertilizers ending up in groundwater, according to a recent study from researchers at the University of California, Davis. The study found heavy rains after a drought caused nitrates to seep 33 feet under farm fields in as little as 10 days.

Anew report from the University of Arizona looks at the challenges that a drying climate poses to agriculture, particularly in arid places such as Arizona. The Future of Agriculture and Food Production in a Drying Climate makes wide-ranging recommendations to help agriculture adapt to an uncertain future, including developing new drought-tolerant crops, improving soil moisture retention, and expanding partnerships with tribal farmers.

Arizona is one of the fastest-growing states in the U.S., with an economy that offers many opportunities for workers and businesses. But it faces a daunting challenge: a water crisis that could seriously constrain its economic growth and vitality.

The earlier the trees bloom, the more likely winter frost will damage the nuts. Early blooms are occurring more often as higher temperatures from climate change stimulate plant growth.
