Seeds of Sustainability tackles a central challenge of sustainable development: agricultural modernization. It is cutting edge not because the issue itself is new, but rather the level of integration the authors attempted and the innovative process they used. The volume summarizes the findings and reflects on the process of a highly interdisciplinary team of researchers, integrating perspectives from: biogeochemistry, atmospheric sciences, land-use change, institutions, agronomy, economics, and knowledge systems. The foundation of the work is rigorous, grounding its findings in multiple peer reviewed publications, while not hesitating to point out gaps or unresolved issues. Seeds of Sustainability includes an in depth historical analysis, which captures issues of path dependence. It demonstrates both originality and critical reflectiveness in its efforts to engage practitioners in the conceptualization and execution of its research, and the implementation of its findings. And almost uniquely in our collective experience, it speaks seriously, frankly, and insightfully to the challenges of institutionalizing the sort of work it reports on.

Stanford scientists joined colleagues in presenting California Gov. Jerry Brown on Thursday with a consensus statement sounding the alarm on climate change and urging action on pollution, population growth, overconsumption and other global environmental challenges.

The document, which was signed by 520 scientists from 44 countries, warns that Earth is rapidly approaching a tipping point, and if nothing changes, "we will suffer substantial degradation."

Forty-eight Stanford scientists endorsed the statement. Rosamond L. Naylor, director of the Center on Food Security and the Environment, was one of eight faculty members who helped draft the statement.

"By the time today's children reach middle age, it is extremely likely that Earth's life-support systems, critical for human prosperity and existence, will be irretrievably damaged by the magnitude, global extent and combination of these human-caused environmental stressors, unless we take concrete, immediate actions to ensure a sustainable, high-quality future," the scientists write in a summary of the statement.

Before receiving the statement, Brown said it's important that scientists communicate clearly to the public.

"We're in a war here in the contest of ideas," he said. "You have to reach people who are skeptical, disinterested and maybe even somewhat hostile."

Later, he urged those who support the statement to spread its message.

"You have to become missionaries," the governor said.

The statement, "Maintaining Humanity's Life Support System in the 21st Century," offers broad-brush solutions for challenges including climate change, loss of eco-diversity, extinctions, pollution, population growth and overconsumption of resources.

"It's important to start fixing these problems today – not next week, next year or next decade," the statement's lead author, Anthony Barnosky, a University of California-Berkeley integrative biology professor and Cox Visiting Professor in Stanford's Department of Environmental Earth System Science, said before the event. "We want to deliver this message to every world leader in government, business, religious institutions and people in all walks of life. These are big problems, but they are fixable."

Among the scientists who joined Barnosky on the stage when he presented the statement to Brown were Stanford Woods Institute Senior Fellows Rodolfo Dirzo, Paul Ehrlich, Elizabeth Hadly and Stephen Palumbi, as well as Anne Ehrlich, a senior research scientist in Stanford's Biology Department.

"This statement deciphers decades of science describing how humans have radically changed the planet," said Hadly, one of 23 senior fellows at the Stanford Woods Institute for the Environment who signed the statement. "I hope it helps policymakers of California and the world practice effective global stewardship."

Among the statement's recommendations:

• Replace fossil fuels with carbon-neutral energy sources such as solar, wind and biofuels
• Promote energy-efficient buildings, transportation and manufacturing systems
• Plan adaptation measures for climatic impacts such as sea-level rise
• Recognize the long-term economic benefits and intangible gains that accrue from protecting natural ecosystems, and act accordingly in dealing with pressures such as overfishing
• Improve the efficiency of food production and distribution
• Slow and eventually stop world population growth by ensuring access to education, economic opportunities and health care, including family planning services, with a special focus on women's rights

The effort grew out of a conversation between Brown and Barnosky, lead author of a 2012 paper warning that Earth is approaching a tipping point beyond which the planet's climate and biodiversity will be radically and unalterably changed beyond anything humanity has known.

"Governor Brown asked me last year why, if global change is such a big deal, scientists are just publishing in scientific journals and not translating their findings into terms that policymakers, industry and the general public can understand and start to address," Barnosky said.

"In 30 years, there are a few things that people will credit us for doing now or bemoan our failure if we don't," said statement co-author Stephen Palumbi, a professor of biology at Stanford and director of the university's Hopkins Marine Station. "Grappling with climate change, and stopping it, is the best gift we can give the future, because unstopped it will crack our society and impoverish our children."

The statement's signers include two Nobel Prize winners and dozens of members of national academies of science around the world.

In addition to Naylor, the other Stanford faculty who helped write the document were Gretchen Daily, Rodolfo Dirzo, Anne Ehrlich, Paul Ehrlich, Elizabeth Hadly, Harold A. Mooney, and Stephen Palumbi.

The 40 other Stanford faculty members who signed the statement are Kenneth J. Arrow, Khalid Aziz, Sally Benson, Carol Boggs, Meg Caldwell, Page Chamberlain, Craig Criddle, Larry Crowder, Lisa Curran, Giulio De Leo, Rob Dunbar, Marcus Feldman, Scott Fendorf, Tad Fukami, Christopher Gardner, Deborah Gordon, Phil Hanawalt, Craig Heller, Martin Hellman, Jamie Jones, Pat Jones, Donald Kennedy, Julie Kennedy, Jeffrey R. Koseff, Eric Lambin, Stephen Luby, Gil Masters, Perry McCarty, Sue McConnell, Michael McGehee, Fiorenza Micheli, Jonathan Payne, Kabir Peay, Dmitri Petrov, Erica Plambeck, Terry Root, Ross Shachter, Robert Street, Peter Vitousek and Charley Yanofsky.

Rod Ewing, a mineralogist and materials scientist who is an expert on nuclear waste management and policy, will join Stanford University to focus on sustainable energy, security and environmental research at the intersection of physical science and public policy.

Ewing has been named to a joint appointment as Professor of Geological and Environmental Sciences in the School of Earth Sciences and a Senior Fellow at the Center for International Security and Cooperation, within the Freeman Spogli Institute for International Studies. He also becomes the inaugural Stanton Professor in Nuclear Security Studies, an endowed chair established with a $5 million gift from the Stanton Foundation.

Ewing was appointed by President Barack Obama in 2012 to serve as the chair of the Nuclear Waste Technical Review Board, which is responsible for the technical review of Department of Energy activities related to transporting, packaging, storing and disposing of spent nuclear fuel and high-level radioactive waste.

Ewing, who earned his Ph.D. at Stanford and was granted a patent for the development of a highly durable material for the immobilization of excess weapons plutonium, is currently the Edward H. Kraus Distinguished University Professor in the Department of Earth & Environmental Sciences at the University of Michigan.

He will take up his new position at Stanford next January and will help bridge Earth Sciences and CISAC to encourage collaboration on scientific and public policy projects.

“What is important to me is to be able to see the connections between subjects that, at first glance, do not appear to be connected,” said Ewing, a former visiting professor at CISAC. His research will continue to focus on the response of materials to extreme environments and the increasing demand for strategic minerals for use in the development of sustainable energy technologies.

Ewing, who has been at the University of Michigan for 16 years, will take advantage of Stanford’s state-of-the-art laboratory facilities, such as the Stanford Synchrotron Radiation Lightsource, for his work on the response of materials to extreme environments.

Ewing said in the past five years there has been growing interest in the performance of materials under extreme conditions, such as inside a nuclear reactor.

“There is a practical interest because new types of materials may form under extreme conditions that have never been previously synthesized,” he said. “And in some cases, these new materials may have very useful properties.”

He expects to teach courses in nuclear security, mineralogy, and energy issues.

Pamela A. Matson, the Chester Naramore Dean of Earth Sciences at Stanford, said Ewing would help the school define a program in strategic minerals.

“This is an area of renewed interest to us, particularly in light of the need for these resources in renewable energy technologies,” Matson said. “To address the sustainability challenges of the 21^st century, we need to both innovate in science and technology areas, and also understand the social and political environments in which decisions are made – and Rod does both. We believe he will help us build a strong partnership between the School of Earth Sciences and CISAC, thus strengthening Stanford’s efforts to solve critical environment and energy problems.”

Ewing spent a year on sabbatical at CISAC during the 2010-2011 academic year. “The quality and diversity of topics really swept me away; everything from terrorism, to nuclear issues to the ethics of war,” he said of his year in Encina Hall.

“Rod Ewing will serve as a vital bridge between science and policy,” said Mariano-Florentino Cuéllar, Co-Director of CISAC.  “His research addresses fundamental questions about nuclear energy with enormous importance to global security.”

Ewing’s interest in nuclear science was sparked in childhood, when he saved up his allowance to buy the Disney book, “Our Friend the Atom.”

“Looking back at the book, one might call it propaganda, but it certainly captured my imagination,” said Ewing, who would go on to author or co-author more than 600 research publications and become the founding editor of the magazine, “Elements.”

As a graduate student on a National Science Foundation grant, he worked on a neglected field of metamict minerals, a relatively rare group of minerals damaged by radiation emitted by uranium and thorium atoms. The study of these unusual minerals in the last 30 years has blossomed into a broadly based research program on radiation effects in complex ceramic materials. This has led to the development of techniques to predict the long-term behavior of materials, such as those used in radioactive waste disposal.

Ewing will continue to chair the Nuclear Waste Technical Review Board as the DOE continues its efforts to find, characterize and license a geological repository for highly radioactive nuclear waste.

“The first issue at hand in the United States is to develop a process for selecting a repository site,” said Ewing. “The challenge will be to combine scientific and technical criteria with the consent of local communities, tribal nations and states.”
