Sustainable Systems Analysis Group
Since 2016, a team of University of California scientists has been working on an NSF/USDA-funded project whose goal is to comprehensively assess the interactions of food-energy-water systems and use the results to model future scenarios for California. (NSF:EAR-1639318, USDA-NIFA:12225279)
Climate effects on Chinese air pollution deaths
PNAS | August 12, 2019

Future climate change may exacerbate the impacts of Chinese air pollution by increasing the frequency and duration of weather conditions that enhance pollution exposure. Under a scenario that avoids 3°C of mean warming but holds emissions constant, we estimate 12,100 and 8,900 more Chinese will die each year from PM2.5 and ozone exposure, respectively.

Flexibility and intensity of global water use
Nature Sustainability | June 3, 2019

Some water uses are more or less flexible than others due to larger curtailment costs or social impacts. We construct and present a new water stress index that integrates water scarcity, flexibility, and variability, and use it to evaluate the most-stressed basins worldwide.

Hydrogen production using photovolatics and solid oxide steam electrolyzers
Electrochem. Energy Conversion & Storage | April 12, 2019

Student Saeedmanesh and Co-PI Brouwer present detailed dynamic model results to show that a solid oxide electrolysis system can follow dynamic PV generation on sunny and cloudy days with reasonable efficiency while maintaining the stack temperature gradient below a maximum set point.

Spatiotemporal error in rainfall data: Consequences for epidemiologic analysis of waterborne diseases
American Journal of Epidemiology | January 25, 2019

Postdoc Levy and co-authors evaluate the implications of spatiotemporal error in precipitation data on assessing exposures to waterborne disease, and suggest that investigators should pay greater attention to limitations in using spatially heterogeneous environmental data sets to assign exposures in epidemiologic research.

Net-zero emissions energy systems
Science | June 29, 2018

PI Davis, Co-PI Brouwer and collaborators review technological opportunities and barriers for eliminating and/or managing difficult-to-decarbonize services, and critical areas for further research, development, demonstration and deployment.
