Anticipating Opportunities: Using Intelligence to Shape the Future
"We spend $45 billion annually to reduce uncertainty, to help us combat threats to our nation, our people, and our security," said Payne Distinguished Lecturer Thomas Fingar in his third Payne lecture on October 21, devoted to anticipating the future -- "not for purposes of prediction but for purposes of shaping it."  Noting that strategic intelligence treats the future neither as "inevitable or immutable," Fingar employed real-life examples from his career in national intelligence (most recently as deputy director of national intelligence for analysis and chairman of the National Intelligence Council) to explore concrete ways intelligence can be used to move developments in a more favorable direction.

Global Trends 2025: A Transformed World examined the trends which will "drive, shape and constrain" individuals, governments, and nations around the world. Among prominent trends, he cited globalization, which will provide unprecedented prosperity but greater inequality; the rise of the BRIC countries - Brazil, Russia, India, and China; the rise of new powers such as Indonesia, Turkey, and Iran; and the coming demographic boom, which will add 1.2 billion people to the world, with less than 3 percent of that occurring in the West.

The Geopolitical Implications of Climate Change.  Instructed by the Congress to provide an assessment of the impact of global climate change, given controversy about the imminence of the threat and man's role in it, the NIC studied which regions and countries would be most dramatically affected by climate change, with a focus on water, food production, and changes in weather patterns. The results remain classified, because of the potential impact on vulnerable countries. 

The 2007 National Intelligence Estimate on Iran's Nuclear Intentions and Capabilities. This estimate, attacked from both the right and the left, concluded with a moderate to high degree of confidence that Iran had not obtained sufficient fissile material from external sources (to make a bomb) and that its fastest route to produce a nuclear weapon would be through domestic production of enriched uranium. The NIE also judged that Iran had halted the weaponization portions of its nuclear program in 2003, but had retained the option to pursue a weapon and whether to do so was a "political decision" which could be made at any time.

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."

Synthetic fertilizers have dramatically increased food production worldwide. But the unintended costs to the environment and human health have been substantial. Nitrogen runoff from farms has contaminated surface and groundwater and helped create massive "dead zones" in coastal areas, such as the Gulf of Mexico. And ammonia from fertilized cropland has become a major source of air pollution, while emissions of nitrous oxide form a potent greenhouse gas.

These and other negative environmental impacts have led some researchers and policymakers to call for reductions in the use of synthetic fertilizers. But in a report published in the June 19 issue of the journal Science, an international team of ecologists and agricultural experts warns against a "one-size-fits-all" approach to managing global food production.

"Most agricultural systems follow a trajectory from too little in the way of added nutrients to too much, and both extremes have substantial human and environmental costs," said lead author Peter Vitousek, a professor of biology at Stanford University and senior fellow at Stanford's Woods Institute for the Environment.

"Some parts of the world, including much of China, use far too much fertilizer," Vitousek said. "But in sub-Saharan Africa, where 250 million people remain chronically malnourished, nitrogen, phosphorus and other nutrient inputs are inadequate to maintain soil fertility."

Other co-authors of the Science report include Woods Institute Senior Fellows Pamela Matson, dean of Stanford's School of Earth Sciences, and Rosamond L. Naylor, director of the Program on Food Security and the Environment.

China and Kenya

In the report, Vitousek and colleagues compared fertilizer use in three corn-growing regions of the world--north China, western Kenya and the upper Midwestern United States.

In China, where fertilizer manufacturing is government subsidized, the average grain yield per acre grew 98 percent between 1977 and 2005, while nitrogen fertilizer use increased a dramatic 271 percent, according to government statistics. "Nutrient additions to many fields [in China] far exceed those in the United States and northern Europe--and much of the excess fertilizer is lost to the environment, degrading both air and water quality," the authors wrote.

Co-author F.S. Zhang of China Agriculture University and colleagues recently conducted a study in two intensive agricultural regions of north China in which fertilizer use is excessive. Their results showed that farmers in north China use about 525 pounds of nitrogen fertilizer per acre (588 kilograms per hectare) annually--releasing about 200 pounds of excess nitrogen per acre (227 kilograms per hectare) into the environment. Zhang and his co-workers also demonstrated that nitrogen fertilizer use could be cut in half without loss of yield or grain quality, in the process reducing nitrogen losses by more than 50 percent.

At the other extreme are the poorer countries of sub-Saharan Africa, such as Kenya and Malawi. In a 2004 study in west Kenya, co-author Pedro Sanchez and colleagues found that farmers used only about 6 pounds of nitrogen fertilizer per acre (7 kilograms per hectare)--little more than 1 percent of the total used by Chinese farmers. And unlike China, cultivated soil in Kenya suffered an annual net loss of 46 pounds of nitrogen per acre (52 kilograms per hectare) removed from the field by harvests.

"Africa is a totally different situation than China," said Sanchez, director of tropical agriculture at the Earth Institute at Columbia University. "Unlike most regions of the world, crop yields have not increased substantially in sub-Saharan Africa. Nitrogen inputs are inadequate to maintain soil fertility and to feed people. So it's not a matter of nutrient pollution but nutrient depletion."

The contrast between Kenya and China is dramatic and will require vastly different solutions, the authors said. However, large-scale change is possible, they said, noting that since the 1980s, increasingly stringent national and European Union regulations and policies have reduced nitrogen surpluses substantially in northern Europe.

In the Midwestern United States, over-fertilization was the norm from the 1970s until the mid-1990s. During that period, tons of excess nitrogen and phosphorus entered the Mississippi River Basin and drained into the Gulf of Mexico, where the large influx of nutrients has triggered huge algal blooms. The decaying algae use up vast quantities of dissolved oxygen, producing a seasonal low-oxygen dead zone in the Gulf that in some years is bigger than the state of Connecticut.

Since 1995, the imbalance of nutrients--particularly phosphorus--has decreased in the Midwestern United States, in part because better farming techniques have increased yields. Statistics show that from 2003 to 2005, annual corn yields in parts of the Midwestern United States and north China were almost the same, even though Chinese farmers used six times more nitrogen fertilizer than their American counterparts and generated nearly 23 times the amount of excess nitrogen.

"U.S. farmers are managing fertilizer more efficiently now," said co-author Rosamond Naylor, who is also a professor of environmental Earth system science and senior fellow at Stanford's Freeman Spogli Institute for International Studies. "The dead zone in the Gulf of Mexico persists due to continued fertilizer runoff and animal waste from increased livestock production."

Low nitrogen in Africa

In sub-Saharan Africa, the initial challenge is to increase productivity and improve soil fertility, the authors said. To meet that challenge, co-author Sanchez recommends that impoverished farmers be given subsidies to purchase fertilizer and good-quality seeds. "In 2005, Malawi was facing a serious food shortage," he recalled. "Then the government began subsidizing fertilizer and corn seeds. In just four years production tripled, and Malawi actually became an exporter of corn."

Food production is paramount, added co-author G. Philip Robertson, a professor of crop and soil sciences at Michigan State University. "Avoiding the misery of hunger is and should be a global human priority," Robertson said. "But we should also find ways to do this without sacrificing other key aspects of human welfare, among them a clean environment. It doesn't have to be an either/or choice."

For countries where over-fertilization is a problem, the authors cited a number of techniques to reduce environmental damage. "Some of these--such as better-targeted timing and placement of nutrient inputs, modifications to livestock diets and the preservation or restoration of riparian vegetation strips--can be implemented now," they wrote.

Designing sustainable solutions also will require a lot more scientific data, they added. "Our lack of effective policies can be attributed, in part, to a lack of good on-farm data about what's happening with nutrient input and loss over time," said co-author Alan Townsend, an associate professor of ecology and evolutionary biology at the University of Colorado-Boulder. "Both China and the European Union have supported agricultural research that yields policy-relevant information on nutrient balances. But the U.S. is particularly lacking in long-term data for a country with such a well-developed scientific enterprise."

Even in Europe, with its strong research programs on nutrient balances and stringent policies for reducing fertilizer runoff, nitrogen pollution remains substantial. "The problem of mitigation of excess nitrogen loss to waters is not easily resolved," said co-author Penny Johnes, director of the Aquatic Environments Research Centre at the University of Reading, U.K. "Society may have to face some difficult decisions about modifying food production practices if real and ecologically significant reductions in nitrogen loss to waters are to be achieved."

According to Vitousek, it is important in the long run to avoid following the same path to excess in sub-Saharan Africa that occurred in the United States, Europe and China. "The past can't be altered, but the future can be and should be," he said. "Agricultural systems are not fated to move from deficit to excess. More effort will be required to develop intensive systems that maintain their yields, while minimizing their environmental footprints."

Biofuels such as ethanol offer an alternative to petroleum for powering our cars, but growing energy crops to produce them can compete with food crops for farmland, and clearing forests to expand farmland will aggravate the climate change problem. How can we maximize our "miles per acre" from biomass?

Researchers writing in the May 7, 2009, edition of the journal Science say the best bet is to convert the biomass to electricity rather than ethanol. They calculate that, compared to ethanol used for internal combustion engines, bioelectricity used for battery-powered vehicles would deliver an average of 80 percent more miles of transportation per acre of crops, while also providing double the greenhouse gas offsets to mitigate climate change.
 
"It's a relatively obvious question once you ask it, but nobody had really asked it before," said study co-author Christopher B. Field, director of the Department of Global Ecology at the Carnegie Institution. "The kinds of motivations that have driven people to think about developing ethanol as a vehicle fuel have been somewhat different from those that have been motivating people to think about battery electric vehicles, but the overlap is in the area of maximizing efficiency and minimizing adverse impacts on climate."

Under the aegis of the Forum on Contemporary Europe, Ambassador Jan Eliasson, former U.N. Special Envoy to Darfur, visited Stanford and FSI to offer a new model for global crisis management of a wide range of issues, from piracy to global poverty.   As the former president of the U.N. General Assembly, Eliasson called for concerted action by NATO, the European Union, the U.N., and other actors on pressing security and humanitarian issues.  Arguing that current security and humanitarian challenges are greater than at any time in recent memory, Eliasson urged that world powers, along with international institutions, seek new leadership from the Obama administration grounded in recognition of the global impact of regional crises. 

To make his case for seeing the global in the regional, Eliasson raised the specter of the escalating sea piracy off the coast of Somalia.  Pirates in that region launch from the shores of a failed state – a polity that has degenerated into rival war-lord militias after combined forces of U.N. and Western powers lost their appetite for engagement, and turned their attention elsewhere.  While much of the world is refocused on the wars in Iraq and Afghanistan, multinational corporations are increasingly subject to and pay out multi-million dollar ransoms for the release of ship crews and cargoes that include the world’s commercial arms shipments.  The piracy has grown beyond instances of local plunder, into crime that threatens one of the most heavily trafficked shipping lanes between western and emerging markets.  Merchant marine as well as naval fleets have been forced to change course, altering global transportation and security routes.  Most recently, Eliasson’s call for international leadership would seem to have been heeded by nations attending the international summit in Brussels on the piracy crisis.  At the summit, the E.U. foreign policy chief, the U.N. Secretary General, and U.S. officials joined with more than sixty countries – including Iraq – to pledge over $200 million in aid to the Somali government for security and development.  This international cooperation, and attention to root causes, would seem to be the first sign of the kind of vision that Ambassador Eliasson urges for new and more comprehensive response.

Ambassador Eliasson completed his depiction of the most effective international policy responses with a focus on the world problem of poverty.  Drawing on his years of experience in the international and Swedish diplomatic corps, Eliasson explained that in the most impoverished areas of the world, the most effective investment in international aid is that which funds the education of girls and young women.  Teach a girl essential education, and she herself, along with her family, and her community, benefits in manifold ways. Raising his glass, Eliasson noted that great numbers of peoples still do not have access to cheap and clean water – an essential provision for health and development.  Water, and access to its diminishing supply, must be understood by the world’s new leaders as the high stake behind multiple border wars. 

The Forum hosted Ambassador Eliasson at FSI and Stanford for two days of talks to reach multiple audiences.  At a Stanford Speakers Bureau event, Ambassador Eliasson addressed an overflow crowd of students and offered  insights into the crisis in Darfur.  The Forum welcomed the opportunity to bring Ambassador Eliasson, so recently from his mission in Darfur, to spur student interest in the role of international (U.N.) and regional (European Union and African Union) peace keeping operations.  During the same visit to Stanford, the Forum on Contemporary Europe hosted Kerstin Eliasson, Board Member of the European Commission Joint Research Center, and former Assistant Undersecretary of the Swedish Ministry of Education and Science, to speak on research reforms in the European higher education system.  Kerstin Eliasson’s public address was co-hosted with the Forum by the faculty seminar series of the Stanford Institute for Higher Education Research.  The visit by Ambassador Eliasson, and Kerstin Eliasson, was a highlight of spring 2009 research and public dissemination of the Program on Sweden, Scandinavia, and the Baltic Region at the Forum on Contemporary Europe.

Joshua Cohen's Program on Global Justice (PGJ), which explores issues at the intersection of political norms and global political-economic realities, has joined CDDRL Center Director Larry Diamond has announced.  Cohen, a professor of political science, philosophy, and law, came to Stanford from the Massachusetts Institute of Technology (M.I.T.) in 2006 to launch a new program on global justice at FSI.

The aim of his program, Cohen said, "is to build dialogue and research that integrates political values - toleration, fairness, and the common good - into discussions about human rights, global governance, and access to such basic goods as food and clean water."  "These issues of global politics are all ethically consequential," Cohen points out, "and addressing them well requires a mix of philosophical thought with the best current social-scientific research."

CDDRL Director Diamond and Associate Director for research Kathryn Stoner joined in saying "We are delighted to welcome Josh Cohen to our team.  His path-breaking work bridges the normative, empirical, and policy dimensions of our Center's ongoing concerns for democracy, equitable economic development, and the rule of law."

Under Cohen, the Global Justice Program's largest effort has focused on the Just Supply Chains project. As globalization of production creates a need for new models of fair treatment for workers in global supply chains, fresh thinking is also needed on the role of unions, the rights of workers to associate, and the role of trade agreement in promoting just working conditions.

Cohen, Diamond, and Terry Winograd, Stanford professor of computer science, have also initiated a the new Program on Liberation Technology which brings together Stanford colleagues from computer science and applied technology with social scientists to explore ways that new information technologies can improve economic, political, and social conditions in low income countries, and materially improve human lives. As Cohen and Diamond note, Liberation Technology "seeks to understand how information technology can be used to defend human rights, improve governance, empower the poor, promote economic development, and pursue of variety of other social goods."  

A prolific author, Cohen has written extensively on issues of democratic theory, especially the theory of deliberative democracy, and implications of that idea for personal liberty. He is the author with Joel Rogers of On Democracy (1983), Rules of the Game (1986), and Associations and Democracy (1995). A volume of his selected papers, Philosophy, Politics, Democracy is forthcoming from Harvard University Press, and his Rousseau: A Free Community of Equals, is forthcoming from Oxford University press.  

Cohen is also the editor of Boston Review, a bi-monthly magazine of political, cultural, and literary ideas, and has edited 18 books that grew out of forums that appeared in the Review. He moderated the Global Poverty and Development Course offered by Google.org in 2007 for google.com employees. The ten week-course addressed issues ranging from growth and globalization to education and urbanization, and can still be watched on YouTube.

Diamond, Stoner-Weiss, and Cohen are part of the distinguished Stanford faculty group who lead the Just Supply Chains each summer.  This highly competitive program each year selects from 600-800 applicants some 30 rising leaders from major transitioning countries such as Russia, Iran, Iraq, Pakistan, Afghanistan, Nigeria, Kenya, and Zimbabwe and brings them to Stanford to examine and foster linkages among democracy, sustainable economic development, and good governance. As Diamond and Cohen point out, in today's challenging environment, putting new information technologies to socially, politically, and economic constructive uses is a powerful tool and of growing interest to many of these rising leaders from transitioning countries.
