Lori McVay, associate director for finance and administration at the Freeman Spogli Institute for International Studies' Program on Food Security and the Environment (FSE), is one of two recipients of the Marsh O'Neill Award for outstanding contributions to Stanford's research mission.

This year, two staff members - one in the Freeman Spogli Institute for International Studies and another in the School of Medicine - will receive Marsh O'Neill Awards.

Now in its 20th year, the award honors staff members who have made outstanding contributions to Stanford's research mission.

This year's honorees are Lori McVay, associate director for finance and administration at the Program on Food Security and the Environment, a joint program of the Freeman Spogli Institute for International Studies and the Woods Institute for the Environment; and Kathleen Thompson, director of the Research Management Group in the School of Medicine.

The dean of research established the Marsh O'Neill Award in 1990. It was named for its first recipient, Marshall D. O'Neill, who retired that same year after nearly four decades as associate director of the W. W. Hansen Experimental Physics Laboratory. A faculty panel chooses the award winner.

McVay and Thompson will be the 30th and 31st staff members to receive the award.

The award presentation - which includes a check for $5,000 for each winner - will take place at 4 p.m. Monday at the Faculty Club. Anyone who knows either of the winners and would like to congratulate them is welcome to attend.

Her talk asks has the biofuels boom subsided, or are the battles just beginning? Is ethanol and biodiesel production compatible with the broader goals of feeding the world and saving wild biodiversity? Rosamond L. Naylor explores the political, economic, and scientific trade-offs behind the global expansion of crop-based biofuels.

Global agricultural expansion cut a wide swath through tropical forests during the 1980s and 1990s. More than half a million square miles of new farmland - an area roughly the size of Alaska - was created in the developing world between 1980 and 2000, of which over 80 percent was carved out of tropical forests, according to Stanford researcher Holly Gibbs.

"This has huge implications for global warming, if we continue to expand our farmland into tropical forests at that rate," said Gibbs, a postdoctoral researcher in the Department of Environmental Earth System Science and in the Program on Food Security and the Environment, who led the study.

Gibbs and colleagues at several other universities analyzed Landsat satellite data and images from the United Nations to reach their conclusions. Theirs is the first study to map and quantify what types of land have been replaced by the immense area of new farmland developed across the tropical forest belt during the 1980s and 1990s.

While this huge increase was happening within the tropics, agricultural land in the non-tropical countries actually decreased in area.

The study was published this week in the online Early Edition of the Proceedings of the National Academy of Sciences.

The United Nations Food and Agriculture Organization estimates that to keep pace with increasing demand, global agricultural production will have to keep increasing, possibly even doubling by 2050. That would likely lead to millions of additional acres of tropical forest being felled over the next 40 years.

Direct impact on carbon released into atmosphere

"Every million acres of forest that is cut releases the same amount of carbon into the atmosphere as 40 million cars do in a year," Gibbs said.

Most of the carbon released comes from burning the forests, but even if the trees are simply cast aside, the bulk of the carbon from the plants makes its way into the atmosphere during decomposition, she said.

Gibbs and her colleagues found that about 55 percent of the tropical forests that had been cut between 1980 and 2000 were intact forests and another 28 percent were forests that had experienced some degradation, such as some small-scale farming, logging or gathering of wood and brush for cooking or heating fuel.

"The tropical forests store more than 340 billion tons of carbon, which is 40 times the total current worldwide annual fossil fuel emissions," Gibbs said. "If we continue cutting down these forests, there is a huge potential to further contribute to climate change."

The increasing demand for agricultural production stems in part from the ever-growing number of people on the planet, who all want to eat. Additionally, members of the growing middle class in emerging economies such as China and India are showing interest in eating more meat, which further intensifies demand. And incentives to grow crops for biofuel production have increased.

But Gibbs and her colleagues also observed some encouraging signs. The patterns of change in the locations they analyzed made it clear that during the 1990s, less of the deforestation was done by small family farms than was the case in the 1980s and more was done by large, corporate-run farms. Big agribusiness tends to be more responsive to global economic signals as well as pressure campaigns from advocacy organizations and consumer groups than individual small farmers.

In Brazil, where a pattern had developed of expanding soy production by direct forest clearing and by pushing cattle ranching off pastureland and into forested areas, a campaign by Greenpeace and others resulted in agreements by key companies to rein in their expansion. Instead, they worked to increase production on land already in agricultural use.

'Seeing positive changes'

"These farmers effectively increased the yield of soy on existing lands and they have also increased the head of cattle per acre by a factor of five or six," Gibbs said. "It is exciting that we are starting to see how responsive industry can be to consumer demands. We really are seeing positive changes in this area."

Along with wiser use of land already cleared, Gibbs said, improvements in technology and advances in yield intensification also could slow the expansion of farming into the forests.

Other studies that analyzed land use changes between 2000 and 2007 have shown that the pace of cutting down the tropical forests has begun to slow in some regions.

But as long as the human population on the planet continues to grow, the pressure to put food on the table, feed in the barnyard and fuel in the gas tank will continue to grow, too.

"It is critical that we focus our efforts on reducing rates of deforestation while at the same time restoring degraded lands and improving land management across the tropics," Gibbs said. "The good news is that pressure from consumer groups and nongovernmental organizations combined with international climate agreements could provide a real opportunity to shift the tide in favor of forest conservation rather than farmland expansion."

In addition to her position at the Department of Environmental Earth System Science and the Program on Food Security and the Environment, Gibbs is affiliated with Stanford's Woods Institute for the Environment. Jon Foley, a professor of ecology, evolution and behavior, and director of the Institute on the Environment at the University of Minnesota, was Gibbs' PhD adviser when the research was begun. He is a coauthor of the paper.

Initial funding for the project was provided by NASA. Gibbs is currently funded by a David H. Smith Conservation Research Fellowship.

 

FSE Center Fellow David Lobell contributes a commentary to Climate Central on the recent heat wave in Russia, its impact on wheat production and global prices, and what rising temperatures mean in the larger context of climate change and food security.

The heat wave in Russia has captured international media attention, breaking temperature records left and right. It has also captured the attention of commodity traders. You see, in a typical year Russia produces about as much wheat as the United States, and is among the top exporters of wheat flour in the world. But this year, wheat has been decimated in the areas around Moscow, with yield expected to be 30 percent or so below normal. This week Russia announced they are banning all exports of wheat from August 15 through the end of the year. Since late June, wheat prices on the Chicago Board of Trade have risen by 50 percent, to more than $7 a bushel.

It is, and always will be, impossible to say whether a single event is caused by climate change. But we can ask, is this the type of thing we expect to be more common? In terms of warming, we can say with little doubt that heat waves like this will become more common with global warming. Exactly how much more common is tough to say, but it is likely that the average summer in 2050 will be as warm as the warmest summer in the 20th century. I am not aware of anyone who has done the calculation of exactly how common the type of heat experienced this year will be, but based on projections in the UN Intergovernmental Panel on Climate Change (IPCC) reports one can suspect this type of heat wave will be relatively common in Russia in a few decades.

Starting winter 2011, FSE will bring the world's leading policy experts in the fields of food and agricultural development to Stanford University to participate in an integrated seminar series on pro-poor growth and food security policy. The series, funded by a grant from the Bill & Melinda Gates Foundation, will consist of twelve lectures delivered on the Stanford campus over the course of two years.

"Providing food security for a world that will be warmer, more populous, and continually developing requires the implementation of sound policies that enhance agricultural production, incomes, and resource stewardship," said FSE director Rosamond L. Naylor.

"New ideas and exchanges are needed to meet this challenge and this seminar series intends to facilitate that process."

Participants will address the major themes of hunger and rural poverty, agricultural productivity, resource and climate constraints on agriculture, and food and agriculture policy. The series will draw heavily from economics, and will embrace polices related to demand, supply, price formation, marketing, trade and development.

"We focus this series on policy because it has proven to be extremely difficult to develop successful projects for hunger and poverty alleviation without first ensuring that sound policies are in play," noted Walter P. Falcon, FSE deputy director and project director. "Even the best-designed programs and projects at the local scale often fail due to counter-productive national policies."

The specific challenges will be to supply sufficient food at reasonable prices, to provide economic access to that food by all segments of society, and to do so without destroying the environment in the process, said Naylor.

In addition to lecturing, participants will write a significant paper that brings together new, relevant thinking about a particular topic area. At the end of the series, a volume of edited papers on international food security and food policy issues will be published. The volume will be designed for M.A. programs and mid-career professionals-individuals who later in their careers will have policy responsibilities. All the materials, including the videotaped lectures, will be freely available on the FSE website.

"We see an important opportunity to complement other efforts that have been funded by the Gates Foundation," said Naylor. "For example, the lecture series and educational volume are expected to contribute to the curriculum of the new Collaborative Master of Science in Agricultural and Applied Economics (CMAAE) program of the African Economic Research Consortium, partially funded by the foundation."

The lecture series will also target audiences in South Asia, and in particular India where there are more malnourished people than in all of sub-Saharan Africa.

The grant also provides funding to produce a specialized educational unit on food policy and food security for high school students. FSE will work closely with Stanford Program on International and Cross-Cultural Education (SPICE) to complete this project.

With the renewed interest in food, agriculture, and food security, it is important that the next generation have access to thoughtful commentary about global food issues, said Falcon.

This grant is part of the foundation's Agricultural Development initiative, which is working with a wide range of partners to provide millions of small farmers in the developing world with tools and opportunities to boost their yields, increase their incomes, and build better lives for themselves and their families. The Foundation is working to strengthen the entire agricultural value chain-from seeds and soil to farm management and market access-so that progress against hunger and poverty is sustainable over the long term.
