There are only two ways to reduce groundwater overdraft: decrease pumping or increase recharge.

While addressing California’s overdraft will certainly require both actions, we convened a meeting of water management experts around groundwater recharge. The goal of the "Recharge Roundtable" was to address California's severe groundwater overdraft problem through actions that would produce substantial increases in recharge in the next five years. 

As a collaboration between the...

The depletion of California's aquifers by overpumping of groundwater has led to growing interest in "managed aquifer recharge," which replenishes depleted aquifers using available surface waters, such as high flows in rivers, runoff from winter storms, or recycled waste water. At the same time, there is growing concern about contamination of groundwater supplies with nitrate from fertilizers, septic tanks, and other sources.

Researchers at UC Santa Cruz...

Drought, climate change, aging infrastructure, and growing population threaten the water used in California's San Joaquin Valley. The San Joaquin Valley supplies most of the nation's produce and a large proportion of its livestock and dairy. Water scarcity in this region can create a ripple effect felt far beyond it.

"Adequate water for food for the nation is a water security issue, and it's also a national security issue." – Roger Bales, UC Water Co-Director and UC Merced Professor of...

“The question is,...

UC Merced student Lorenzo Booth uses maps to find the best climate for crops

The California drought has exacerbated some of the challenges farmers face.

For example, they have to spend more on water, and not just because there is less to go around. A warmer climate causes water to evaporate faster and can force plants to consume more for the same amount of growth.

But researchers at the University of California, Merced, are finding where crops would use water most efficiently so...
