Growing up I always wanted one thing around this time of year: a ride with Santa. Yes, a sky-high journey with that burly, bearded Claus who reportedly could offer children a chance to see the world differently. It seemed like an adventure to me, one that would surely offer a more thorough understanding of Christmas.

As summer recedes and December approaches it appears that my wish was granted this past summer while riding shotgun to and from a farm near the small town of Ashland, Nebraska alongside a man who seemed to a twenty-year-old everything I imagined Santa Claus to be at age seven. For five weeks in the company of a farm operator I had the opportunity to broaden my understanding of commercial food production and the managerial complexity, associated risk, and arrant talent involved in much of agriculture today.

Our driving conversations soon carried over into late mornings and afternoons—anytime when the space for conversation transpired. “The marketplace is fiercely competitive,” he would say to explain the indistinct security governmental support for crop production provides. Daily, his business was subject to environmental and market persuasions. Although federal insurance policies and subsidies were valuable for his business, he was still one of many farmers who jockeyed within a bullish and bearish economy. Prior to hedging his crops, for example, he had to contemplate the eminent yield successes on farms in Iowa in addition to this summer’s drought-induced crop loss in Argentina. But he also could not forget about policy makers in China and Europe who through their governmental measures influence world demand and supply of staple grains. These conversations depicted the realities of an interdependent food market around the globe and helped me distinguish applications of macro-agricultural studies.

Familiarizing myself with the farm’s operations did not come without mistakes, however. I will never forget the dexterous and visionary employees who taught me not just that wearing shorts while working on a farm is equivalent to modeling a Speedo at a consulting interview, but more importantly how complicated producing food is with advanced mechanized systems. Whether it be welding an auger for grain transfer, converting a piece of scrap metal into a rotating laptop computer harness for the cattle chute, or actually building a propane-powered irrigation pump, the competency of those with whom I worked was remarkable. I learned untold lessons and skills from colleagues, reminding me that a cattle pen could also be an educational setting.

I could spend many more months in Ashland refining my tractor driving capabilities and acquiring more knowledge of agricultural management and economics. I wish I could witness the crops reach adulthood and the combines combing those matured fields during the autumn months. Yet, I am grateful for the time I had there, and what I learned will help guide me as I continue to navigate through complex issues facing U.S. agriculture and international food security.

This year I will still anticipate Christmas and its enduring celebrity, but I will rest in bed just a bit more calmly on Santa’s night. My conversations in a Toyota truck this summer and the knowledge gained from the entire experience in Nebraska have sated my sleigh-riding hunger and enhanced my studies of food’s complexities. This farm experience was that kind of ride for me, allowing me to evaluate the impact of U.S. commercial farmers within a global agricultural network, admire those who cultivate what we eat, and seek a deeper understanding of food as a livelihood and resource.

Aquaculture, once a fledgling industry, now accounts for 50 percent of the fish consumed globally, according to a new report by an international team of researchers. And while the industry is more efficient than ever, it is also putting a significant strain on marine resources by consuming large amounts of feed made from wild fish harvested from the sea, the authors conclude. Their findings are published in the Sept. 7 online edition of the Proceedings of the National Academy of Sciences (PNAS).

"Aquaculture is set to reach a landmark in 2009, supplying half of the total fish and shellfish for human consumption," the authors wrote. Between 1995 and 2007, global production of farmed fish nearly tripled in volume, in part because of rising consumer demand for long-chain omega-3 fatty acids. Oily fish, such as salmon, are a major source of these omega-3s, which are effective in reducing the risk of cardiovascular disease, according to the National Institutes of Health.

"The huge expansion is being driven by demand," said lead author Rosamond L. Naylor, a professor of environmental Earth system science at Stanford University and director of the Stanford Program on Food Security and the Environment. "As long as we are a health-conscious population trying to get our most healthy oils from fish, we are going to be demanding more of aquaculture and putting a lot of pressure on marine fisheries to meet that need."

Fishmeal and fish oil

To maximize growth and enhance flavor, aquaculture farms use large quantities of fishmeal and fish oil made from less valuable wild-caught species, including anchoveta and sardine. "With the production of farmed fish eclipsing that of wild fish, another major transition is also underway: Aquaculture's share of global fishmeal and fish oil consumption more than doubled over the past decade to 68 percent and 88 percent, respectively," the authors wrote.

In 2006, aquaculture production was 51.7 million metric tons, and about 20 million metric tons of wild fish were harvested for the production of fishmeal. "It can take up to five pounds of wild fish to produce one pound of salmon, and we eat a lot of salmon," said Naylor, the William Wrigley Senior Fellow at Stanford's Woods Institute for the Environment and Freeman Spogli Institute for International Studies.

One way to make salmon farming more environmentally sustainable is to simply lower the amount of fish oil in the salmon's diet. According to the authors, a mere 4 percent reduction in fish oil would significantly reduce the amount of wild-caught fish needed to produce a pound of salmon – from 5 pounds of wild fish to just 3.9 pounds. In contrast, reducing fishmeal use by 4 percent would have very little environmental impact, they said.

"Reducing the amount of fish oil in the salmon's diet definitely gets you a lot more bang for the buck than reducing the amount of fishmeal," Naylor said. "Our thirst for long-chain omega-3 oils will continue to put a lot of strain on marine ecosystems, unless we develop commercially viable alternatives soon."

Naylor and her co-authors pointed to several fish-feed substitutes currently being investigated, including protein made from grain and livestock byproducts, and long-chain omega-3 oils extracted from single-cell microorganisms and genetically modified land plants. "With appropriate economic and regulatory incentives, the transition toward alternative feedstuffs could accelerate, paving the way for a consensus that aquaculture is aiding the ocean, not depleting it," the authors wrote.

Vegetarian fish

Fishmeal and fish oil are important staples at farms that produce carnivorous fish, including salmon, trout and tuna. But vegetarian species, such as Chinese carp and tilapia, can be raised on feed made from plants instead of wild-caught fish. That's one reason why farm-raised vegetarian fish have long been considered environmentally friendly.

In the early 1990s, vegetarian fish farms began adding small amounts of fishmeal in their feed to increase yields. However, between 1995 and 2007, farmers actually reduced the share of fishmeal in carp diets by 50 percent and in tilapia diets by nearly two-thirds, according to the PNAS report. Nevertheless, in 2007, tilapia and carp farms together consumed more than 12 million metric tons of fishmeal – more than 1.5 times the amount used by shrimp and salmon farms combined.

"Our assumption about farmed tilapia and carp being environmentally friendly turns out to be wrong in aggregate, because the sheer volume is driving up the demand," Naylor said. "Even the small amounts of fishmeal used to raise vegetarian fish add up to a lot on a global scale." Removing fishmeal from the diet of tilapia and carp would have a very positive impact on the marine environment, she added.

Regulating fisheries

On the policy front, Naylor pointed to the 2006 California Sustainable Oceans Act and the proposed National Offshore Aquaculture Act, which call for reductions in the use of fishmeal and fish oil in feeds. She also applauded plans by the National Oceanographic and Atmospheric Administration to develop a comprehensive national policy that addresses fisheries management issues posed by aquaculture. "No matter how much is done from the demand side, it is essential that there be regulation on the supply side as well," Naylor said. "You won't prevent the collapse of anchoveta, sardine and other wild fisheries unless those fisheries are carefully regulated."

Development of new crop varieties that are more heat and drought tolerant will be critical for successful adaptation to a warmer world. A recent 3 day meeting of international climate and crop experts at Stanford University focused on specific needs and promising approaches for improving crops. A meeting synopsis and recommended priorities can be found in a summary report, Climate Extremes and Crop Adaptation.

Rising leaders from some of the world’s most complex and challenging nations, including China, Russia, Ukraine, Iraq, Kenya, Nigeria, South Africa, and the Democratic Republic of the Congo, have just completed a three-week seminar at Stanford as Draper Hills Summer Fellows on Democracy and Development. This year’s extraordinary class of fellows included members of parliament, government advisors, civic activists, leading jurists, journalists, international development experts and founders of non-governmental organizations (NGOs).

Each year, several hundred applicants apply to FSI’s Center on Democracy, Development, and the Rule of Law (CDDRL), the convener of the program, for the 26-28 slots available to study and help foster linkages among democracy, economic development, human rights, and the rule of law. Now in its fifth year, the program has received generous gifts from William Draper III, a Silicon Valley entrepreneur, in honor of his father, Maj. Gen. William H. Draper, Jr., a chief advisor to Gen. George Marshall and chief diplomatic administrator of the Marshall Plan in Germany, and Ingrid von Mangoldt Hills, a former journalist, in honor of her husband, Reuben Hills, a leading San Francisco philanthropist and president and chairman of the board of Hills Bros. Coffee.

Draper Hills Summer Fellows are innovative, courageous, and committed leaders, who strive to improve governance, enhance civic participation, and invigorate development under very challenging circumstances," said CDDRL Director Larry Diamond. “This year’s fellows were absolutely extraordinary, learning from us we hope, but also teaching all of us about the progress they are making and the obstacles they confront in a diverse set of countries.  We were not only sobered by the difficulties they must address on a daily basis but also uplifted by their accounts of programs that are working to deepen democracy, improve government accountability, strengthen the rule of law, energize civil society, and enhance the institutional environment for broadly shared economic growth.”

The three-week seminar is taught by an all star faculty, which in addition to Diamond, includes CDDRL Deputy Director Kathryn Stoner, Stanford president emeritus and constitutional law expert Gerhard Casper, FSI Deputy Director and political science professor Stephen D. Krasner, Erik Jensen and Allen S. Weiner from the Stanford law school, Avner Greif from the Department of Economics, Peter Henry from the Graduate School of Business, FSI Senior Fellow Helen Stacy, former FSI Director and current Program on Food Security and the Environment deputy director Walter P. Falcon, Mark C. Thurber, acting director of FSI’s Program on Energy and Sustainable Development, and Nicholas Hope, director of the Stanford Center on International Development.

Other leading experts and practitioners who engaged the fellows included democracy and governance expert Francis Fukuyama, who joins CDDRL as Olivier Nomellini Senior Fellow in July 2010, National Endowment for Democracy President Carl Gershman, United States Court of Appeals Judge Pamela Rymer, International Center on Nonviolent Conflict founding chair Peter Ackerman, the center’s president, Jack DuVall, former Peruvian president Alejandro Toledo, and former Secretaries of State George Shultz and Condoleezza Rice.

Faculty devoted the first week of the seminar to defining the fundamentals of democracy, good governance, economic development, and the rule of law, and in the second week turned to the issue of transitions and the feedback mechanisms between democracy, development, and a predictable rule of law. The third week examined the critical – and often controversial – role of international assistance to foster and support democracy, judicial reform, and economic development, including the proper role of foreign aid.

Against this backdrop, fellows emphasized domestic imperatives for fostering growth, social inclusion, and transformation, centering on the importance of political will and sound institutions.  In session after session, they wrestled with the concrete and all too common impediments to progress—from corruption, cronyism, and authoritarian regimes, to the fragility of conflict-ridden, multi-ethnic polities.  As an activist from strife-torn Iraq said, “Democracy is not just a way of governing. It is a way of living, a way of thinking about life.”“Democracy is not just a way of governing. It is a way of living, a way of thinking about life”

In spirited debates, in the formal seminar sessions and beyond the classroom to the Munger residence where the fellows stayed, the fellows stressed how they had all taught and learned from each other.  A rising leader from South Africa aptly summarized, “We have dispelled each other’s myths.”

As the Draper Hills Fellows expressed their profound gratitude to their faculty and mentors, they reinforced the importance of staying in touch through a virtual online community – a “common space” as defined by a member of parliament from Ukraine, that would let them look forward and look back, perhaps a decade from now, at case studies of success and failure, and the all important roles that political will and leadership played in determining outcomes.  “Stay tuned,” said Diamond and Stoner-Weiss. “Important lessons are still to come.”
