blog post The Weird Weather of 2023: Better Get Used to It By Jeffrey Mount, Gokce Sencan, Michael Dettinger Sep 27, 2023 Water Year 2023 comes to an end on September 30. For most weather-watchers, this was an unusual year, with very wet conditions following several very dry years—but are the frequency and intensity of these variations increasing as the planet’s temperature rises? And if so, what might be the implications for water management? We take a look.
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?
blog post Climate-Challenged California Must Learn to Thrive with Less Water By Ellen Hanak, Jeffrey Mount Nov 16, 2022 Managing water in our increasingly volatile climate is becoming more challenging: even if we do everything right, water supplies are likely to decline. The grand challenge for 21st-century water management in California is learning to thrive with less.
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.
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.
