Fact Sheet

Water Use in California’s Communities

By Andrew Ayres, Caitlin Peterson, Annabelle Rosser

Even as California’s population has grown by millions, its per-capita water use has declined. Communities are finding ways to boost resilience in the face of climate change.

Policy Brief: The Future of Agriculture in the San Joaquin Valley

By Alvar Escriva-Bou, Ellen Hanak, Spencer Cole, Josué Medellín-Azuara

Agriculture is a key driver of the regional economy in the San Joaquin Valley, but water for irrigation is an ongoing—and growing—concern. Our latest research offers the most accurate, nuanced, and localized look at where fallowing may need to occur—and details the policy and management actions that could lead to better outcomes.

Fact Sheet

Water and Energy in California

By Alvar Escriva-Bou, Gokce Sencan, Andrew Ayres

Water and energy are closely entwined in California: the energy sector relies heavily on water for electricity generation, and statewide water use consumes a lot of energy. Our new fact sheet illuminates the connections between these two sectors, and explores ways to make both systems more resilient in the face of climate change.

Solar Energy and Groundwater in the San Joaquin Valley

By Andrew Ayres, Annabelle Rosser, Ellen Hanak, Alvar Escriva-Bou ...

Hundreds of thousands of acres of irrigated farmland may come out of production in the San Joaquin Valley in coming decades. At the same time, the state needs to ramp up renewable energy generation to meet climate goals. Could solar development on fallowed land help the valley’s residents? Our new report examines the challenges and opportunities.

Storing Water for the Environment

By Sarah Null, Jeffrey Mount, Brian Gray, Kristen Dybala ...

Large reservoirs are essential for managing water in California’s highly variable climate—but over the years, the construction and operation of these reservoirs have had significant environmental costs. Our new research outlines how reservoir operations could be changed to improve the health of the state’s fragile freshwater ecosystems.

Policy Brief: Storing Water for the Environment

By Sarah Null, Jeffrey Mount, Brian Gray, Kristen Dybala ...

To protect and restore California’s freshwater ecosystems and respond to the changing climate, California’s water managers must change how they operate reservoirs. Our policy brief offers recommendations for how to do this in a way that makes the most efficient use of scarce water for the environment while minimizing impacts on other water uses.

Statewide Survey

PPIC Statewide Survey: Californians and the Environment

By Mark Baldassare, Dean Bonner, Rachel Lawler, Deja Thomas

Key findings include: Three in ten Californians name water supply and drought as the state’s top environmental issue; nearly seven in ten say the water supply is a big problem in their part of the state. More than half of Californians say higher gas prices have caused financial hardship, and more than four in ten are upset about the current rate of inflation. Most Californians oppose offshore drilling, and an overwhelming majority want to prioritize alternative energy over oil, coal, and natural gas. But views are divided along party lines. Democrats are much more likely than independents and Republicans to support key state climate change policies.

Land Transitions and Dust in the San Joaquin Valley

By Andrew Ayres, Jaymin Kwon, Joy Collins

Agricultural operations and wind erosion are two of the largest sources of dust in the San Joaquin Valley, and the valley’s air quality may decline with increased farmland fallowing and a warmer, drier climate. This will impact low-income, rural communities first and foremost, but proactive management can help identify high-risk areas and direct funding to cost-effective interventions.

Exploring the Potential for Water-Limited Agriculture in the San Joaquin Valley

By Caitlin Peterson, Cameron Pittelkow, Mark Lundy

As irrigated farmland comes out of production in the San Joaquin Valley, valley residents will face increased pests, weeds, and dust—as well as a loss of employment and economic activity. Water-limited cropping is one alternative to fallowing that can improve soil health and air quality, create habitat, and keep land in production.

Fact Sheet

The Sacramento–San Joaquin Delta

By Jeffrey Mount, Ellen Hanak, Greg Gartrell

The Sacramento–San Joaquin Delta is California’s largest estuary and a vital hub in the state’s water supply system. Three interlinked issues currently face the Delta: an increasingly unreliable water supply, a decline in ecosystem health, and a fragile system of levees. Learn more about this key watershed in our new fact sheet.
