blog post Adapting to a Water-Scarce California By Ellen Hanak Jan 9, 2023 With the arrival of a series of atmospheric rivers, drought-weary Californians are now confronting the weather whiplash that’s a hallmark of our state’s climate. But the current deluge won’t erase California’s water challenges. PPIC Water Policy Center director Ellen Hanak reflects on what happened with California’s water in 2022—and explores how to manage the resource in our increasingly volatile climate.
blog post The Promise of a Wet January By Jeffrey Mount Jan 5, 2023 California is in an impressive—and much-needed—wet period. But the current parade of atmospheric rivers also highlights how difficult it is to capture and store water during times of great abundance. Can we do better?
Report Solar Energy and Groundwater in the San Joaquin Valley By Andrew Ayres, Annabelle Rosser, Ellen Hanak, Alvar Escriva-Bou ... Oct 25, 2022 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.
blog post The Environmental Benefits of the Water Storage Investment Program By Gokce Sencan, Jeffrey Mount Sep 26, 2022 The Water Storage Investment Program is the first attempt use public funds to incentivize new water storage for the environment. While the program has faced some challenges, it could prove to be a useful model for future efforts—with some improvements.
Report Storing Water for the Environment By Sarah Null, Jeffrey Mount, Brian Gray, Kristen Dybala ... Aug 22, 2022 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.
Report Land Transitions and Dust in the San Joaquin Valley By Andrew Ayres, Jaymin Kwon, Joy Collins Jul 20, 2022 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.
Report Exploring the Potential for Water-Limited Agriculture in the San Joaquin Valley By Caitlin Peterson, Cameron Pittelkow, Mark Lundy Jul 20, 2022 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 May 18, 2022 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.
Policy Brief Policy Brief: Tracking Where Water Goes in a Changing Sacramento–San Joaquin Delta By Greg Gartrell, Jeffrey Mount, Ellen Hanak May 16, 2022 The Sacramento–San Joaquin Delta supplies water to roughly 30 million Californians, over 6 million acres of farmland, and countless ecosystems. But the watershed’s climate is changing: recent decades have seen record warmth, higher evaporation, and declining snowpack. We track where the water is going—and how to adapt.
Policy Brief Policy Brief: Drought and California’s Agriculture By Alvar Escriva-Bou, Josué Medellín-Azuara, Ellen Hanak, John Abatzoglou Apr 13, 2022 California’s agricultural sector is the nation’s largest: it generates more than $50 billion dollars in annual revenue and employs more than 420,000 people. The ongoing drought is taking a toll on agriculture, related sectors, and rural communities, but there are ways to increase resilience in a warming world.
