Security

FSI scholars produce research aimed at creating a safer world and examing the consequences of security policies on institutions and society. They look at longstanding issues including nuclear nonproliferation and the conflicts between countries like North and South Korea. But their research also examines new and emerging areas that transcend traditional borders – the drug war in Mexico and expanding terrorism networks. FSI researchers look at the changing methods of warfare with a focus on biosecurity and nuclear risk. They tackle cybersecurity with an eye toward privacy concerns and explore the implications of new actors like hackers.

Along with the changing face of conflict, terrorism and crime, FSI researchers study food security. They tackle the global problems of hunger, poverty and environmental degradation by generating knowledge and policy-relevant solutions.

On April 13, Kenneth Roth, Executive Director of Human Rights Watch discussed Obama's human rights record to an audience of over 125 students and faculty, marking Roth's first speaking engagement at Stanford University. This event was hosted by the Program on Human Rights at the Center on Democracy, Development, and the Rule of Law, and was the final installment of the Sanela Diana Jenkins International Human Rights Speaker Series.

David Abernethy, Professor Emeritus of Political Science at Stanford University, introduced Roth and provided a detailed overview of his professional background and the stunning growth and impact Human Rights Watch has witnessed since Roth took the helm in 1993. Under Roth's leadership and strategic direction, Human Rights Watch tripled in size, expanding its reach to over 90 countries worldwide. 

"Human rights Watch does a remarkable job in combining carefully documented facts with advocacy for a better world, including naming and shaming egregious violators of universally accepted norms," said Abernethy, in emphasizing the courageous work Human Rights Watch pioneers on a global scale.

Abernethy noted that Human Rights Watch is a "is a north, south, east, west NGO, directed towards all points on the compass and operating from all those points, as a truly globalized institution."

At the outset of his comments, Roth framed President Obama's human rights record as a desire to abandon the principles of the George W. Bush administration and embrace an approach that is in stark contrast to the Bush years of unilateral diplomacy.

Obama has evolved -- it has been a journey from being not George Bush to being himself.
- Kenneth Roth

Since assuming office in 2009, Roth noted, "Obama has evolved -- it has been a journey from being not George Bush to being himself."

Roth highlighted the differences between both presidents, emphasizing the fact that, "most significantly in terms of contrast, Obama was going to lead by example," Roth said. "He was going to have a domestic policy that he and we could be proud of and that would persuade others just by virtue of what the US did itself."

In reflecting on the evolution of Obama's approach to human rights since assuming office, Roth saw Obama moving from rhetoric to practice. Roth cited a number of examples where the Obama administration delivered substantially on their commitment to defend these principles and others where they had fallen short.

In terms of multilateral promotion of human rights, Roth discussed how the Obama administration supported the efforts of the United Nation's Human Rights Council by successfully lobbying for the U.S. to become a member and helping to revive the Council into a more effective body in holding governments accountable. 

According to Roth, "the Council has introduced tough resolutions on Libya, the Ivory Coast, Iran, and revived this tool and the ability of a group of a government's peers to condemn it."

Roth also mentioned how the Obama administration has been a key player in supporting the International Criminal Court (ICC) by voting in favor of referring Libya to the ICC, arresting the leader of the Lord's Resistance Army in the Congo, and exerting pressure on Sudan to surrender President Bashir.

These actions, Roth maintained, "strengthened a key international institution designed to stop the impunity that lies behind so many of the world's worst atrocities."

While, Roth thought Obama had certainly struck a much more modest tone on the world stage than Bush, he did stress that Obama had retained the option of humanitarian intervention and is not afraid to use military force when necessary, highlighting the recent examples of Libya and Cote d'Ivoire.

Roth believed that Obama's biggest shift was towards China's human rights record. In 2009, Obama was hesitant to exert pressure on the Chinese concerning their human rights practice, which proved to be an ineffective strategy in advancing US interests. Since the January 2011 China summit in Washington, Obama dramatically reasserted himself, calling on China to expand human rights protections and realized "human rights is not a dangerous topic."

In surveying the Obama administration's policy in the Middle East and North Africa, Roth judged it as "inconsistent" toward the recent pro-democracy movements where strategic concerns have sometimes outweighed more ideological ones.

In Egypt, Roth believed the administration took too long to take an active stand against Mubarak in support of the protesters, but eventually came around to prove they were "better late than never."

Similarly in Yemen, Roth described the administration as hesitant to initially oppose President Saleh because it jeopardized their relationship with an important counter-terrorism ally.

In Bahrain, Roth explained that the administration refuses to take an active stance and continues to discuss the possibility of reconciliation in light of the flagrant human rights abuses committed at the hands of the Bahraini regime. Roth claimed that Obama is acting in the best interest of the US's Saudi partners who are "terrified" at the prospect of a Shiite revolution in Bahrain. 

Roth characterized the administration's position towards Israel as a "predictable disappointment," in that the US vetoed a UN Security Council resolution classifying the settlements as a violation of international law and rejected the Goldstone report, refusing to recognize the positive aspects of this comprehensive investigation of the war in Gaza.

On domestic policies, Roth commended Obama's immediate effort to end the Bush policy of torture and shutter the CIA secret detention facilities, but was disappointed that Obama refused to prosecute the Bush torturers and investigate where the torture took place. 

Roth described the issue of long-term detention without trial as a work in progress, believing that Obama's hesitation to release a core group of 48 prisoners in Guantanamo stemmed from his concerns about potential future acts of terrorism. 

In closing, Roth was optimistic about Obama's evolution over the past two years, noting the great strides he has taken to actively implement his values in US human rights policy. However, he was cautious in highlighting the tensions that exist between US interests and human rights, claiming that Obama still has a ways to go in striking a better balance between the two.

This event was a rare opportunity for the CDDRL community to hear from a leading investigator and critic of human rights abuses, committed to reducing human suffering on a global scale.

The challenges of reducing global hunger and poverty are different today than they were 30 years ago. Current challenges include price volatility associated with increased integration of food, energy, and finance markets; the steady progression of climate change; poorly defined land institutions; and a failure to break vicious cycles of malnutrition and infectious disease. Farmland speculation is occurring globally—often at odds with rural poverty alleviation—and food insecurity remains a pressing issue with the estimated number of chronically malnourished people hovering around one billion. Given these patterns, food and agriculture are becoming increasingly ingrained in international security and policy discussions. This paper explores several ways in which the traditional field of agricultural development needs to expand to address the broader issues of international security and human welfare. It focuses on five key interrelated issues: the macroeconomic and energy contexts of agricultural development; climate change; deforestation, land access, and land markets; farming systems and technology for the ultra-poor; and food-health linkages with a specific focus on infectious disease. Recommendations for investments in capacity building, revised curricula, and development projects are made on the basis of evidence presented for each issue. It is clear that academic programs, government agencies, development and aid organizations, and foundations need to dismantle the walls between disciplinary and programmatic fields, and to find new, innovative ways to reach real-world solutions.

On April 11, the Center on Democracy, Development, and the Rule of Law (CDDRL) hosted an event to celebrate the release of Francis Fukuyama's latest book, The Origins of Political Order: From Prehuman Times to the French Revolution. The occasion drew an audience of over 100 faculty, students, and members of the community, who were eager to hear Fukuyama introduce the first volume of this "magnum opus," which traces the history of the development of political institutions through the eighteenth century. Fukuyama was joined by two Stanford faculty members to provide commentary on the book; Ian Morris, Professor of Classics and History, and Barry Weingast, Senior Fellow at the Hoover Institute.



The Origins of Political Order: From Prehuman Times to the French Revolution
Francis Fukuyama
Farrar, Strauss, and Giroux, 2011
608 pages

Fukuyama is the Olivier Nomellini Senior Fellow at the Freeman Spogli Institute and in residence at CDDRL since July 2011, coming to Stanford from the Johns Hopkins School of Advanced International Studies (SAIS). CDDRL Director, Larry Diamond opened the event by commenting on how CDDRL is the ideal intellectual home for the Origins of Political Order, which examines democracy, development, and the rule of law from an evolutionary perspective. Diamond discussed the richness and breadth of Fukuyama's scholarship, which is not confined to one region or discipline but is truly global and interdisciplinary in nature, underpinning the philosophy and approach of CDDRL's research agenda.

Fukuyama provided the audience with an overview of how he conceived of writing such a sweeping account of political development, which began when his former teacher and mentor, the late Samuel Huntington asked him to write the forward to a new version of the 1968 classic, Political Order in Changing Societies. It occurred to him that there was little scholarship available that focused on where institutions first originated and how they evolved throughout human history. Fukuyama stressed the practical importance of this empirical question and its application to the present day, as Arab states struggle to create viable political institutions in the wake of revolution. 

Fukuyama described modern political order as consisting of three characteristics that are the foundational analysis of his book--the state, rule of law, and accountability. In discussing the evolution of the state, Fukuyama characterized it as the "long term historical struggle against a family."

Examining history through an anthropological lens, Fukuyama described early societies as orderly, with specific rules based on biologically grounded mechanisms, favoritism towards kin, and reciprocal altruism. Cooperation among relatives and friends is something that "every human society defaults to in the absence of institutions that provide different incentives," said Fukuyama.

These early social orders evolved into modern states once patrimonialism was replaced by a more impersonal form of politics, and citizens were no longer favored based on their ties to the ruler. Fukuyama traces the first modern state to ancient China during the time of the Qin dynasty in the third century BC, which created an impersonal, rational, and centralized bureaucracy that diverged from the patrimonial systems of the past. Similarly, in the Muslim world a system of military slavery was adopted by the Ottoman empire to break young men's allegiance to their family and generate loyalty to the Sultan.  

While state institutions were constructed in the Arab, Hindu, and Chinese worlds, underneath these systems, Fukuyama stressed, are strong kinship groups that continued to influence the formation of the modern state. By contrast, he claimed, "Europe is the only world civilization that gets beyond kinship on a social but not a political level."

Examining the development of rule of law, Fukuyama described it as, "an outgrowth of religious law administered by a hierarchy residing outside the state that puts limits on the executive." In order to institutionalize law, a cadre of legal specialists were trained and law was made coherent through codification.

Something that I find striking about the rise of democracy or accountable government in Europe is how accidental and contingent it is.
- Francis Fukuyama

Fukuyama discussed how the sequence in the development of institutions can often be an accident of history that will ultimately determine its type of governance. "Something that I find striking about the rise of democracy or accountable government in Europe is how accidental and contingent it is," Fukuyama continued, "you would not have democratic institutions in the west were it not for the survival of certain feudal institutions into the modern period."

European monarchical authority was limited by feudal institutions called estates, parliaments, sovereign courts, and the like, consisting of the upper nobility, gentry, and bourgeoisie, which served as a balance of power against the central state. Fukuyama argued that this ultimately led to constitutional governance in England, but not in France, Spain, Russia, or Hungary, were parliaments were weak and divided.

Stanford historian and classicist Ian Morris, author of Why the West Rules for Now, lent an historical account of Fukuyama's book, commenting on the breadth of the scholarship and soundness of his historical judgment, which he views as a rarity in academia. On the whole Morris agreed with Fukuyama's argument, particularly the way he stressed the evolutionary basis of social and political change.

However, he disagreed with a specific detail of Fukuyama's analysis, where he classified the Qin dynasty as the first modern state. Instead, Morris views the Qin as part of a broader package of shifts occurring during the 1st millennium BCE, from China to the Mediterranean basin where patrimonial states evolved toward more "high-end type states," which separate political power from kinship networks.

On a deeper level, Morris believes there are more similarities than differences in patterns of human development. The biggest divergences did not occur until the last 500 years when according to Morris, "geographical forces have driven the rule of law, accountable government, and all that's happened since the French Revolution."

Barry Weingast, Professor of Political Science at Stanford and Senior Fellow at the Hoover Institution, provided a theoretical examination of The Origins of Political Order, discussing the important gap Fukuyama's book fills in defining political development since Huntington's seminal 1968 piece.

Weingast highlighted two areas of the book--the role of ideas and the issue of violence. According to Weingast, the role of ideas is a causal feature of Fukuyama's analysis but he does include ancient Greece and Rome, telling the story of republics and how ideas defined their political development. Weingast discusses the dilemma that lies at the heart of governance from the time of the Romans to the early American republic, which is characterized as a 2,000-year struggle of how to scale-up into larger societies, capable of defending themselves from other larger societies.

Examining the concept of violence, Weingast argues that Fukuyama does not give enough attention to the theoretical element of violence and challenges the way he conceptualizes it through Max Weber's definition of a modern state, which "has a monopoly on the legitimate uses of violence."

The debut of Fukuyama's treatise on political development left everyone in the room with a fresh perspective on where modern institutions evolved from to more fully understand their characteristics and complexities today. We look forward to the second volume of this book, which will bring the story up to the present day.

Former President Gerhard Casper launched the Asia-Pacific Scholars Program (AP Scholars Program) in 1997 to strengthen and expand Stanford University's ties with Asia. The program was loosely modeled on Oxford University's Rhodes Scholarship. Led by renowned China scholar Michel Oksenberg of the Asia/Pacific Research Center (the predecessor organization of the Walter H. Shorenstein Asia-Pacific Research Center), the first program brought together a highly diverse class of nineteen graduate students from the United Kingdom, the United States, and numerous countries in Asia. The AP Scholars Program thrived under Oksenberg's direction, but fell dormant for nearly a decade following his death in 2001.

Thomas Fingar, the Oksenberg/Rohlen Distinguished Fellow at the Freeman Spogli Institute for International Studies and a former chairman of the National Intelligence Council, re-launched the AP Scholars Program in September 2010. "I am delighted to have been asked to revive it," states Fingar.


The film Pacific Vision: The Asia-Pacific Scholars Program at Stanford University was released to commemorate the program's inaugural year. A clip from Pacific Vision, featuring interviews with Casper and Oksenberg, is available here courtesy the Stanford University Archives.

Full video of the symposium is now available - Why Has Africa Been Slow in Developing its Agriculture?

A poor African farmer produces a little more corn than last year. He sells the surplus in a nearby urban market, and uses the money to purchase a shirt stitched by a local seamstress. With the bumper crop of corn, more and more farmers are interested in the seamstress' wares. The extra income allows her to buy better materials and a new sewing machine. Her business grows, and she begins to sell her work in bigger markets, further from her small village.

Years later, a poor farmer responds to an announcement for a job in a local clothing factory. The monthly wage is more than he currently makes in a year.

This is the vision that Dr. Ousmane Badiane, Africa Director for the International Food Policy Research Institute, presented to an audience of Stanford students and faculty on April 7. In a two-hour symposium entitled "Why Has Africa Been Slow in Developing its Agriculture?," Badiane outlined the steps he believes African nations must take to sustain economic growth and encourage high-value industrial development. Public investment in agriculture formed the backbone of his proposal.

Badiane said that although African nations have experienced unprecedented economic growth in the last 15 years, they still lag behind the developed world in economic sophistication. When workers leave agriculture for other sectors, he explained, the transition usually signifies economic progress.

But in Africa, too many farmers have abandoned their fields to peddle trinkets on the streets as part of a low-productivity service sector. They have left behind an underdeveloped and understaffed agricultural industry.

Agriculture has just plummeted too fast and too quickly in these countries," Badiane said. "Agriculture is not claiming the share of GDP and employment that it should."

When agriculture thrives, Badiane explained, economies grow and diversify. A wealthier rural population purchases products manufactured by urban entrepreneurs. Productive local farms buffer fluctuations in global crop output and food prices, improving security for urban industrial workers and reducing wage pressure on industrial employers.

"What agriculture needs is what industry needs," Badiane said, emphasizing that investment in one need not mean neglect of the other. "There are a lot of things you can do right by all the sectors at the same time."

In fact, according to Badiane, every $100 increase in agricultural output could result in up to a $130 increase in output from industry.

Badiane described one step that African governments have already taken to set the positive agriculture-industry feedback in motion. The Comprehensive Africa Agriculture Development Program is a cooperative effort by the African Union's 53 member nations to achieve ambitious goals for economic development and investment in agriculture by 2015.

Badiane commended the Program's unprecedented commitment to agricultural growth and its high standards for accountability, policy research, and performance review. He also praised the political momentum and unity that the initiative has generated within Africa, and the respect that it has earned in the international community.

However, Badiane admitted that agricultural growth in Africa cannot always proceed in harmony with other objectives. The need to finance agricultural research and development will put pressure on budgets for broader public welfare programs that Dr. Joel Samoff, a Stanford professor of African Studies, says most African nations simply cannot afford to de-fund.

"Most countries in Africa spend around $10 per person per year on health," says Samoff. "How do you reduce that?"

But Badiane suggested that governments may be able to address both agriculture and welfare simultaneously.

They will have to see how they can use social service budgets to sustain growth in agriculture," he said. "Look at health and education not as an entitlement, but as a tool to raise labor productivity."

Addressing the audience during a question-and-answer session following Badiane's talk, Harvard Development Professor, Emeritus, Peter Timmer drew attention to the scope of Badiane's objectives.

"You're talking about getting industry moving at the same time as you're getting agriculture moving," he noted, "and this is a very ambitious undertaking."

However, Timmer also indicated that he saw the seeds of success in Badiane's ideas. "I think we've just heard a quite profound analysis of Africa's agricultural problems, and its structural history," he said. "And a possible way forward."

Sugarcane - a principal crop for biofuel - reduces the local air temperature compared to pasturelands or fields growing soybeans or maize, according to a new study from researchers at Stanford University and the Carnegie Institution for Science. But sugarcane's effect on temperature is a "double-edged machete," as it increases ambient temperatures compared with natural vegetation.

These small local changes should be taken into consideration in studies of global climate change, the researchers said.

The researchers looked at changes in vegetation in the Brazilian Cerrado - a vast tropical savanna lying south of the Amazon basin - large areas of which have been converted from natural vegetation to agriculture in recent decades.

Increasingly, these existing agricultural areas are now being converted to sugarcane for use in biofuel production. Brazil is now second only to the United States in ethanol production, much of which is used domestically.

What the effect on global climate would be if sugarcane farming were to expand significantly is not yet clear, said David Lobell, an assistant professor in environmental Earth system science at Stanford and center fellow at the Program on Food Security and the Environment.

"The temperature changes are happening locally, where the land-use change is happening," Lobell said. "It does not seem to spill over into other countries, for example, at least as far as we can tell right now."

But Lobell said sugarcane growing in the Cerrado is definitely expanding and given that the region encompasses approximately 1.9 million square kilometers (733,000 square miles) - an area larger than Alaska - the potential exists for a globally significant effect.

Using maps and data from hundreds of satellite images, the researchers calculated the temperature, the amount of water given off and how much light was reflected rather than absorbed for each of the different types of vegetation. They found that compared to land cultivated with other annual crops, sugarcane reduced the local air temperature by an average of 0.93 degrees Celsius (1.67 F).

But compared to the natural vegetation of the Cerrado - mainly grass and shrubs - the sugarcane fields warmed the ambient air by 1.55 C (2.79 F).

Lobell said the bulk of the temperature difference is due to evapotranspiration - the moisture released to the air through the leaves of the plants and the soil. Most of the land put into sugarcane had previously been converted from natural vegetation to pastureland, said Scott Loarie, a postdoctoral researcher at Carnegie. "If someone has a farm that once was natural vegetation, that transition to pasture and annual crops caused local warming," he said. "So now as the farm is going to sugarcane, by comparison it is cooling temperatures locally."

Their research, Direct Impacts on Local Climate of Sugarcane Expansion in Brazil, is described in the current issue of Nature Climate Change.

This local cooling does not necessarily mean that the global climate is cooling as a result. It depends in part on what happens with the agriculture that was displaced by the sugarcane, Loarie said. For example, if cattle used to graze on a tract of land and some Amazon forest is cut down to provide new pasture for them, net carbon emissions will actually increase.

"You might not make any difference as far as cooling the world globally at all; in fact, you might make the world marginally warmer," he said.

"The global implications of these local effects were not a part of this study, and any discussion of mitigating global climate should consider the potential for these land use cascades."

One of the important aspects of the study, Lobell said, is that it demonstrates how satellite data can be used in real time to understand the effects of environmental changes. Most research studying the impact of biofuel use on climate has been done with computer modeling.

"I think the coolest thing about this study is you actually can see these temperature effects happening already," Lobell said. "In terms of the more general point about bio energy, I think it is another good example of why looking only at greenhouse gases is not the full picture."

Another takeaway from the study, Loarie said, is that the temperature findings support the existing rule of thumb that biofuel crops are best located on land that is already used for agriculture. That general guideline stems from the fact that there is less carbon released to the atmosphere by converting land where the existing vegetation contains low amounts of carbon, such as pasture or crops, than by cutting down the dense, carbon-rich forests in the Amazon.

Loarie said that while the study clearly showed that planting sugarcane moves the temperature closer to what it would have been if the natural vegetation had not been removed from the land, that doesn't mean the land is any closer to its natural state in other respects.

"Converting pasture to sugarcane is definitely not ecological restoration," said Chris Field, a professor of biology and of environmental Earth system science, who was involved in the research.

"Still, the direct effect on climate is potentially important enough to play a role in future decisions about land use and land management in large parts of the tropics," he said.

The study was funded by the Stanford University Global Climate and Energy Project.

Greg Asner, a professor, by courtesy, of environmental Earth system science, is a coauthor of the paper. Lobell is also a center fellow at both the Freeman Spogli Institute for International Studies and the Woods Institute for the Environment. Field is also a senior fellow at the Precourt Institute for Energy and at the Woods Institute, and director of the Department of Global Ecology at the Carnegie Institution.
