California's agriculture faces challenges from a highly variable climate with temperatures that will increase over the next several decades. Droughts are worsening and the Sierra snowpack, integral to the water supply, is volatile.

However, there are a number of ways to mitigate those changes, as outlined in a new paper coauthored by a group of UC faculty.

California's agriculture faces challenges from a highly variable climate with temperatures that will increase over the next several decades. Droughts are worsening and the Sierra snowpack, integral to the water supply, is volatile.

However, there are a number of ways to mitigate those changes, as outlined in a new paper coauthored by a group of UC faculty.

As the climate continues to change, the risks to farming are only going to increase.

That's the key takeaway from a recent paper published by a team that included UC Merced researchers. The paper dives into what those challenges are, how farmers are working to address them and what should come next.

Almost 3 billion people worldwide are projected to suffer from severe water scarcity by 2025. Thousands have already been affected in California alone, where more than 1,200 wells ran dry in 2022.

It's never been more important to find ways to make the best use of this precious resource.

Agriculture is in a time of daunting challenge: The world's population is growing and climate change is impacting every area of the food supply chain.

Researchers from across the country who are working to address that challenge met at UC Merced this week. They are part of the Internet of Things for Ag, a National Science Foundation-funded research center uniting the University of Pennsylvania, UC Merced, Purdue University and the University of Florida.

“Raise your hands if you want to know a secret,” acclaimed author and cartoonist Jorge Cham instructed a crowd of young children. Hundreds of tiny arms shot up in unison toward the cafeteria ceiling.

“Butterflies drink with a straw,” he said. Bustling with excitement, the students expressed their astonishment with “oohs” and “wows.”

Federal and state government officials journeyed to the western corner of Merced County on Thursday to announce a new project to place solar panels on the water in the Delta-Mendota Canal.

The project is part of a $19 million investment through President Joe Biden’s Inflation Reduction Act announced by the Department of the Interior to install panels over irrigation canals in California, Oregon and Utah, with the aims of decreasing evaporation of critical water supplies and advancing clean energy goals.

Water is among the most precious resources on the planet. Some areas don't get enough; some get too much. And climate change is driving both of those circumstances to ever-growing extremes.

University of California researchers from the USDA-funded Secure Water Future project recently found that increases in crop water demand explain half of the cumulative deficits of the agricultural water balance since 1980, exacerbating water reliance on depleting groundwater supplies and fluctuating surface water imports.

The new film "California's Watershed Healing" documents the huge benefits that result from restoring forests to healthier densities. UC Merced's Sierra Nevada Research Institute partnered with the nonprofit Chronicles Group to tell the story of these efforts, the science behind them, and pathways that dedicated individuals and groups are pioneering to scale up these urgent climate solutions.
