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...

California aims to lead the nation — and the globe — in climate change research, policy and action — in large part through climate-focused research conducted at University of California campuses and labs.

Some of that research, including from UC Merced, will be on display this week as climate-change scientists, policymakers and trailblazers from around the globe gather in San Francisco for the...

UC Water Researcher, Graham Fogg, participated in the American Geosciences Institute's Policy and Critical Issues webinar on July 18th, 2018. View the webinar below. Series: AGI Policy & Critical Issues Webinar

This 1 hour AGI Critical Issues webinar introduced the geoscience of managing groundwater storage and recharge, discussed groundwater storage policies and research in California and Texas, and reviewed case studies and potential future developments.

Background:Groundwater is...


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...

Recharge Net Metering to Enhance Groundwater SustainabilityThe Center for Law, Energy & the Environment at UC Berkeley School of LawIncreasing recharge of aquifers will be a crucial component for achieving groundwater sustainability in California. A key challenge lies in creating incentives that will motivate landowners, tenants, and other stakeholders to develop recharge projects.    Recharge Net Metering (ReNeM) is a strategy that encourages recharge by offsetting costs of distributed...

UC Water Director weighs in on opportunities for managing forests for wildfire, water supply, and climate change.

“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...
