Environment & Engineering

David Sedlak

Professor of civil and environmental engineering , co-director of the Berkeley Water Center
Phone: (510) 643-0256
Email: sedlak@ce.berkeley.edu

Sedlak is author of "Water 4.0: The Past, Present and Future of the World's Most Vital Resource" (Yale Press, 2014), and the deputy director of Re-inventing the Nation's Urban Water Infrastructure (ReNUWIt), a research center funded by the National Science Foundation and led in partnership with Stanford University.

Sedlak's research area focuses on environmental chemistry, water quality engineering and ecological engineering. He can discuss the options of water reuse, or augmenting water supplies with municipal wastewater effluent.

He notes that cities that rely upon groundwater supplies of water are in a much better position to weather the drought than those that rely upon surface water supplies, such as reservoirs and aqueducts. But he adds that all cities should diversity their sources of water to manage the risks of drought.

Kara Nelson

Professor in Civil and Environmental Engineering
Phone: (510) 643-5023
Email: karanelson@berkeley.edu

Nelson's research program addresses critical issues at the intersection of public health and the environment, with a focus on reducing the threat posed by waterborne pathogens by improving our engineering infrastructure to make it more effective, affordable, as well as maximize its environmental benefits.  Specific research areas include mechanisms of pathogen inactivation, molecular techniques for pathogen detection, optimizing treatment processes, water reuse, and challenges with providing safe drinking water and sanitation in the developing world. She is the Director of Graduate Education at the Engineering Research Center for Reinventing our Nation’s Urban Water Infrastructure (ReNUWIt), and the faculty leader of the Research Thrust Area on Safe Water and Sanitation at Berkeley Water Center.  Dr. Nelson was awarded the Presidential Early Career Award for Scientists and Engineers (PECASE) at a ceremony in the White House in 2004.  This award is the nation’s highest honor for scientists in the early stages of their career.  She currently conducts research in the United States, India, Bangladesh, Kenya, Panama, and Colombia.

CA Water History & Politics

B. Lynn Ingram


Professor of earth and planetary science and of geography
Phone: (510) 643-1474
Email: ingram@eps.berkeley.edu
 
Ingram, co-author (with Frances Malamud-Roam) of "The West Without Water: What Past Floods, Droughts, and Other Climatic Clues Tell Us About Tomorrow" (UC Press, 2013), is a paleoclimatologist who studies rocks, sediments, shells, microfossils and trees for clues to changes in climate that occurred long before humans arrived in the Western Hemisphere.

Ingram says that California has had a thousand-year history of megadroughts and megafloods. Some, such as the flood of 1861-62 that left Sacramento and most of the Central Valley underwater, occurred within historical memory. "If you go back thousands of years, you see that droughts can go on for years if not decades, and there were some dry periods that lasted over a century," she said.

Head of the Laboratory for Environmental and Sedimentary Isotope Geochemistry (LESIG) at UC Berkeley, Ingram focuses on the chemistry of fossil shells taken from sediment beneath San Francisco Bay. Her study areas include marshlands around the Bay as well as sites in China, Australia and French Polynesia, encompassing terrestrial, coastal, estuarine and coral reef environments.

Agriculture

Maximilian Auffhammer

George Pardee Jr. Chair in Sustainable Development and associate professor of agricultural and resource economic
Phone: (510) 643-5472
Email: auffhammer@berkeley.edu

Auffhammer can address the economic impact of the drought on California agriculture and agricultural labor.  His research also includes the impacts of greenhouse gas emissions and air pollution on agriculture as well as the economic value of irrigation water.

 

DAVID ZILBERMAN

George W. and Elsie M. Robinson Chair in Food and Agricultural Resources Economics
Phone: (510) 642-6570 (office) or (510) 290-9515 (cell) 
Email: zilber@are.berkeley.edu

Zilberman's research interests are agricultural policy, water quality and conservation, economics of technological change and natural resources, and micro-economic theory. He has studied the adoption of modern irrigation technologies in California, and the economics of water markets and water rights. A study he led on how California responded to the drought of 1987-1991 showed the importance of having reservoirs that allow for slowing the impact of drought. The study also demonstrated the capacity of California agriculture to adjust to shortages by increased reliance of groundwater and adoption of conservation tools.
