This past autumn the Freeman Spogli Institute for International Studies (FSI) in conjunction with the Woods Institute for the Environment launched a program on Food Security and the Environment (FSE) to address the deficit in academia and, on a larger scale, the global dialogue surrounding the critical issues of food security, poverty, and environmental degradation.

"Hunger is the silent killer and moral outrage of our time; however, there are few university programs in the United States designed to study and solve the problem of global food insecurity," states program director Rosamond L. Naylor. "FSE's dual affiliation with FSI and the new Stanford Institute for the Environment position it well to make significant steps in this area."

Through a focused research portfolio and an interdisciplinary team of scholars led by Naylor and CESP (Center for Environmental Science and Policy) co-director Walter P. Falcon, FSE aims to design new approaches to solve these persistent and under-prioritized problems, expand higher education on food security and the environment at Stanford, and provide direct policy outreach.

Productive food systems and their environmental consequences are at the core of the program. While many of these systems are global in character, but they are influenced significantly by differing food objectives, income level, and instruments among nations. The program thus seeks to understand the food security issues that are of paramount interest to poor countries, the food diversification challenges that are a focus of middle-income nations, and the food safety and subsidy concerns prominent in richer nations.

Chronic hunger in a time of prosperity

Although the world's supply of basic foods has doubled over the past century, roughly 850 million people (12 percent of the world's population) suffer from chronic hunger. Food insecurity deaths during the past 20 years outnumber war deaths by a factor of at least 5 to 1. Food insecurity is particularly widespread in agricultural regions where resource scarcity and environmental degradation constrain productivity and income growth.

FSE is currently assessing the impacts of climate variability on food security in Asian rice economies. This ongoing project combines the expertise of atmospheric scientists, agricultural economists, and policy analysts to understand and mitigate the adverse effects of El Niño-related climate variability on rice production and food security under current and future global warming conditions. As a consequence of Falcon and Naylor's long-standing roles as policy advisors in Indonesia, models developed through this project have already been embedded into analytical units within Indonesia's Ministry of Agriculture, the Planning Ministry, and the Ministry of Finance.

"With such forecasts in hand, the relevant government agencies are much better equipped to mitigate the negative consequences of El Niño events on incomes and food security in the Indonesian countryside," explain Falcon and Naylor.

Food diversification and intensification

With rapid income growth, urbanization, and population growth in developing economies, priorities shift from food security to the diversification of agricultural production and consumption. "Meat production is projected to double by 2020" states Harold A. Mooney, CESP senior fellow and an author of the Millennium Ecosystem Assessment. "In China alone, meat consumption has more than doubled in the past generation." As a result, land once used to provide grains for humans now provides feed for hogs and poultry.

These trends will have major consequences on the global environment-affecting the quality of the atmosphere, water, and soil due to nutrient overloads; impacting marine fisheries both locally and globally through fish meal use; and threatening human health, as, for example, through excessive use of antibiotics.

An FSE project is looking at these trends as it relates to intensive livestock production and assessing the environmental impacts to gain a better understanding of the true costs of this resource-intensive system. A product of this work recently appeared as a Policy Forum piece in the December 9, 2005, issue of Science titled "Losing the Links Between Livestock and Land".

Numerous factors have contributed to the global growth of livestock systems, lead author Naylor notes, including declining feed-grain prices, relatively inexpensive transportation costs, and trade liberalization. "But many of the true costs remain largely unaccounted for," she says. Those costs include destruction of forests and grasslands to provide farmland for corn, soybeans, and other feed crops destined not directly for humans but for livestock; utilization of large quantities of freshwater; and nitrogen losses from croplands and animal manure.

Naylor and her research team are seeking better ways to track all costs of livestock production, especially the hidden ones related to ecosystem degradation and destruction. "What is needed is a re-coupling of crop and livestock systems," Naylor says. "If not physically, then through pricing and other policy mechanisms that reflect social costs of resource use and ecological abuse."

Such policies "should not significantly compromise the improving diets of developing countries, nor should they prohibit trade," Naylor adds. Instead, they should "focus on regulatory and incentive-based tools to encourage livestock and feed producers to internalize pollution costs, minimize nutrient run-off, and pay the true price of water."

Looking ahead

The future of the program on Food Security and the Environment looks bright, busy, and expansive. While a varied portfolio of projects is in line for the upcoming year, a strong emphasis remains in the area of food security. Building on existing research at Stanford, researchers are identifying avenues for enhancing orphan crop production in the world's least developed countries-crops with little international trade and investment, but with high local value in terms of food and nutrition security. The work seeks to identify advanced genetic and genomic strategies, along with natural resource management strategies, to improve orphan crop yields and stability, enhance crop diversity, and increase rural incomes through orphan crop production.

Another priority area of research centers on the development of biofuels. Biofuels are becoming increasingly a part of the policy set for world food and agriculture. As countries such as the United States seek energy self-reliance and look for alternatives to food and feed subsidies under WTO (World Trade Organization) rules, the conversion of corn, sugar, and soybeans to ethanol and other energy sources becomes more attractive. New extraction methods are making the technology more efficient, and crude oil prices at $60 per barrel are fundamentally changing the economics of biomass energy conversion. A large switch by key export food and feed suppliers, such as the United States and Brazil, to biofuels could fundamentally alter export prices, and hence the world food and feed situation. A team of FSE researchers will assess the true costs of these conversions.

The FSE program recently received a grant through the Presidential Fund for Innovation in International Studies to initiate new interdisciplinary research activities. One such project links ongoing research at Stanford on the environmental and resource costs of industrial livestock production and trade to assess the extent and rate of Brazil's rainforest destruction for soybean production. "Tens of millions of hectares of native grassland and rainforest are currently being cleared for soybean production to supply the global industrial livestock sector," says Naylor. A significant share of Brazil's soybeans is being shipped to China, where rapid income growth is fueling tremendous increases in meat consumption."

A team of remote-sensing experts, ecologists, agronomists, and economists will be looking at the ecological effects on the landscape through biogeochemical changes and biodiversity loss, the impacts of land clearing on the regional hydrologic cycle and climate change, the economic patterns of trade, and the role of policies to achieve an appropriate balance between agricultural commodity trade, production practices, and conservation in Brazil's rainforest states.

"I'm extremely pleased to see the rapid growth of FSE and am encouraged by the recent support provided through the Presidential Fund for Innovation in International Studies," states Naylor. "It enables the program to engage faculty members from economics, political science, biology, civil and environmental engineering, earth sciences, and medicine-as well as graduate students throughout the university-in a set of collaborative research activities that could significantly improve human well-being and the quality of the environment."

Multinational corporations (MNCs) have increasingly located research and development (R&D) in developing countries such as China and India since the 1990s. On the one hand, governments in developing countries are eager to attract R&D to their local economies; on the other hand, developed countries are concerned about losing their competitive advantage due to R&D offshoring. At the same time, intellectual property protection is a growing concern.

What are the MNC R&D labs actually doing in China? Quan noted that her 2004 survey of MNC R&D labs in information technology industries in Beijing found that these MNC R&D labs are not just providing technical support, product localization, or product development for the local market; rather, they are developing products for the global market. Her study documents an emerging spatial division of labor in R&D based on the increasing specialization of R&D activities.

Ensuring returns appropriation

Appropriating returns is essential to continuous R&D investment. However, returns appropriation is not necessarily realized through formal IP protection institutions such as the patent system. As the growing trend of globalization of R&D has evolved to this new stage characterized by MNCs locating R&D labs in developing countries, it provides a good test bed to further explore more theoretical mechanisms of IP protection. Considering the weak intellectual property rights regimes these developing countries typically have, it is crucial for MNCs to find an effective way to protect their valuable technologies thus facilitating returns appropriation from their R&D activities in host developing regions. It is in fact the effective means of IP protection that can greatly assist MNCs' location of R&D offshore, in addition to other well-known incentives such as low cost R&D labor and market attraction.

R&D specialization essential

Using evidence from MNC R&D labs in Beijing and Shanghai, Quan's study proposes that R&D is further specialized within MNCs' global R&D network. Furthermore, IP protection and returns appropriation can be realized through such R&D specialization. The key proposition is formulated as below: 'Hierarchical modular R&D structure can be an effective way for MNC R&D labs to protect their intellectual property and thus facilitate returns appropriation in weak IPR regime developing countries'. This 'hierarchy' includes 'core R&D' and 'peripheral R&D', based on two dimensions--technology value-added, desire and ease of IP protection. While 'core R&D' is mostly done in developed countries, 'peripheral R&D' is conducted in developing countries. Dr. Quan's study suggests that this hierarchical modular R&D structure facilitates the global configuration of MNC R&D labs.

SELECT: What is the current size of the outsourcing market? What percent of U.S. software development, call centers, etc., have already moved to developing nations? Is the amount of outsourcing still increasing?

Dossani: To provide some perspective, although the off-shoring of services has been going on for mans Nears, technology led by the widespread use of the Internet has changed things. The resulting new twist in the provision of services is that the required interaction between the seller and the consumer has been substantially limited. The advances in information technology made possible the parsing of the provision of certain services into components requiring different levels of skill and interactivity As a result, certain portions of the serviced activity that might or might not be skill-intensive, but required low levels of face-to-face interaction could be relocated offshore. The sequence of events that enabled this process is the following:

First, the digital age allowed (or, at least, revolutionized) the conversion of service flows into stocks of information, making it possible to store a service. For example, a legal opinion that earlier had to be delivered to the client in person could now be prepared as a computer document and transmitted to the client via e-mail or, better yet, encoded into software. Easy storage and transmission allowed for the physical separation of the client and vendor as well as their separation in time. It also induced the separation of services into components that were standardized and could be prepared in advance (such as a template for a legal opinion) and other components that were customized for the client (such as the opinion itself) or remained non-storable. Taking advantage of the possibility of subdividing tasks and the economies that come with the division of labor, this reduced costs by offering the possibility of preparing the standardized components with lower-cost

labor and, possibly at another location.

The second fundamental impact of digitization was the conversion of non-information service flows into information service flows. For example, the sampling of tangible goods by a buyer through visiting a showroom is increasingly being replaced by virtual samples delivered over the Internet. Once converted to an information flow, the service may also he converted into a stock of information and subjected to the above mentioned forces of cost reduction through standardization of components and remote production.

Third, the low-cost transmission of the digitized material accelerated the off-shoring of services. Services such as writing software programs which were off-shored to India in the early 1970s were enabled by digitized storage and, in the 1980s, by the standardization of programming languages. Still later, as digital transmission costs fell in

the 1990s (just as digital storage costs had fallen earlier), even nonstorable

services, such as customer care, could he handled offshore.

The offshore services outsourcing market (excluding software development) is still small and will probably be approximately $10 billion for 2005. It employs about 500,000 people, two thirds of whom are located in India. The rest are widely distributed, with developing Asia and Ireland accounting for most of the remaining employment. About 60% of the employment is in call centers. The U.S. and U.K. call-center industry together employ about five million people, so the percentage of offshore jobs is still small. It is even smaller for other services.

Offshore software development employs approximately another 500,000 people. This compares with U.S. employment of about two million. This is a larger percentage of the total software development labor market. although most of the outsourced work is programming, while work such as systems integration and design continue to be done in the U.S.

The growth rate is still high and there are concerns about whether or not this rapid growth rate will hurt the quality of work done. However. this rate will still likely he in excess of 30% in 2005 and 2006. The reason for this is the massive wage differential.

Clearly there have been massive failures as well as outstanding successes in outsourcing. What are the critical success factors for making outsourcing work?

The infrastructure (telecom. finance, power) has all been standardized, although the solutions might not he the same as in developed countries. The critical success factors are two: the quality of labor and supervision; and managing growth. Unbelievable there is a growing shortage of labor. The result is that the quality of work is declining. Project supervisory skills are also in short supply. Managing growth, especially keeping attrition

under control, training, developing new vertical skills, moving into back-office work, and offering the client turnkey packages are some of the critical managerial factors for success.

Short of being willing to work for $15,000/year, what can western IT professionals do to provide sufficient value to prevent their functions from being outsourced?

The U.S. educational system still turns out a good product. It is sufficiently ahead of the comparable Indian product so that a recent computer science/computer engineering graduate from the average U.S. university can earn a premium of at least 100% over his Indian counterpart from a good university such as the IlTs, with substantially higher premiums for graduates from schools such as MIT and Stanford. The problem occurs more with mid-career professionals. Those with older skills are unable to compete with freshly trained graduates from India. Therefore, they need to update those skills regularly and take advantage of opportunities to globalize and convert them into managerial skills. This may have to he mandated at some point, as has happened in the financial sector, where stockbrokers need to regularly sit for exams to renew their licenses.

That said, most of the offshore jobs are relatively low-skilled. For example, the single largest category of offshore services is outbound calling for the financial services industry for selling mortgages or collecting overdue receivables. The work is routine, based on scripts that pop-up on the computer screen in response to prompts.

Do these findings suggest that developed countries are likely to be only marginally threatened by the globalization of services? Even if high-end work is stays within developed countries, as has happened in the software industry, the problem is that not everyone in developed countries can readily shift to high-end work. Since the 1960s, the shift in the economies of developed nations towards service-based economies certainly increased the number of highly-skilled service workers, but there was an even greater swelling in the number of other less-skilled service workers. This is partly a consequence of the nature of many services as linked, inseparable sets of activities with different

skill levels, combined with a pyramid of labor requirements, i.e., there is more demand for lower-level work than for high-end work. In manufacturing. the unemployment created by the reduction in demand for blue collar labor in developed countries was offset by the absorption of much of the surplus labor into service industries, often with minimal training. But the shift of low-end service workers to high-end workers will require a longer period of re-education and may have significant interim consequences on unemployment rates.

The threat to developed countries is increased by the fact that, apart from software, the largest growth in off-shoring is happening in business services. These are also the sectors with the largest growth in U.S. employment.

Further, there is evidence that even higher skilled functions can be moved offshore or might evolve on their own. For example, interviews with people at a firm earlier this year revealed that they had initially been contracted by an American firm to call its clients with overdue credit card payments. The offshore company eventually purchased the receivables from its client and assumed the collection risk itself. Another firm, Wipro Spectramind, managed the radiology services of Massachusetts General Hospital for its second and third shifts. Thus, American radiologists, who earn an average of $315,000 a year were replaced by Indian radiologists, who earn $20,000 a year on average.

I understand that there is a whole subculture in Pakistan and India of people who go to work in the late afternoon or evening and then work a full day on U.S. time. What effect has outsourcing had on the cultures of the countries that are recipients of much of the outsourced work? Have labor rates dramatically increased? Is it difficult for local companies in India and Pakistan to get quality IT talent?

Indeed such a subculture now exists. It is viewed as very stressful work and not suitable for a long-term career. Companies that do such work try to ameliorate the stress by hiring psychiatric counselors to provide free counseling to stressed-out employees. They also provide free meals and transportation, sports facilities, etc.

However, labor rates have increased only, a little. This is more than offset by

the rise in productivity of this labor over time.

Outsourcing is clearly a temporary solution. As labor rates equalize, the benefit of outsourcing decreases. In Pakistan and China, there are still huge differences in labor costs, but in Turkey, rates are closer to what they are in the 11.5. and other Western states. Realistically, how long can we gain a significant benefit form outsourcing?

India and China, and to some extent, Pakistan, have large labor pools. That is why, in manufacturing, Chinese wage rates have not changed despite massive employment growth over the past three decades. I think that wage rates in India will actually fall because of increasing supply, which is being drawn into outsourcing. This would mean several more decades of benefit from outsourcing.

One way in which developed countries may retain value is if their firms control the work done, either through providing the risk capital or through subsidiaries. While it is difficult to predict which organizational types will dominate, a number of firm-specific factors that influence the liability of off-shoring and organization structure are summarized here:

The knowledge component of the activity. A higher knowledge component makes the firm more concerned about whether the quality of the service will change due to a location change or the transfer process.

The interactive components of the process.

The ability to modularize the process

Savings from concentrating an activity in one location, leading to

benefits of scale and scope.

Reengineering as part of the transfer process. To transfer a business process, it is necessary to study it intensively and script the transfer. In the process of study, often there will he aspects of the current methodology for discharging the process that do not add value. Very often these aspects are legacies of earlier methodologies that were not eliminated as the production process evolved. During the act of transfer these are easier to abandon than at an existing facility' where they have become a "natural' part of the daily routine. Our interviews identified other unexpected benefits that go beyond the efficiency effects. Simply examining the business processes may reveal previously undetected inefficiencies. During the transfer process, these inefficiencies can be addressed without disrupting work patterns. Workers in the new location then use the reengineered process which is usually more efficient.

The time-sensitive nature of the work.

What is South Korea's strategic posture in East Asia?

After the Korean War ended in 1953, South Korea and the United States established a political and security alliance that has lasted more than half a century. "For a number of decades, South Korea primarily defined itself as a U.S. ally, with the enemy to the north," says Donald Gregg, president of the Korea Society and a former U.S. ambassador to Korea. However, South Korea is now trying to create a new role for itself in Asia. Seoul is exploring a growing economic relationship with China--which passed the United States in 2003 to become South Korea's largest trading partner--and its policy of engagement and growing cooperation with North Korea is pulling it away from the United States. "All we know for sure is that South Korea's role is no longer junior partner to the U.S.," says David Kang, a visiting professor of Asian studies at Stanford University. "The days when they would just unquestioningly follow the U.S. are over."

Kang and other experts say Seoul is beginning to shift its focus towards increasing regional ties with its Asian neighbors. The U.S.-South Korea relationship, while still strong, is not as exclusive as it has been in the past. "South Korea is still an ally of the United States ... nevertheless, it has been the most active country in promoting East Asian cooperation and integration, and will probably continue to do so," says Charles Armstrong, professor of history and director of the Center for Korean Studies at Columbia University.

What are South Korea's biggest foreign policy challenges?

Dealing with North Korea while preserving its relationship with the United States, maintaining relations with Japan, and addressing potential long-term military or economic threats from China, experts say. But "the major issue for Seoul is overwhelmingly North Korea, and everything else gets filtered through that lens," Kang says. South Korea looks to its northern neighbor with the goal of eventual reunification, and therefore seeks economic cooperation and political engagement to smooth relations and slowly move down that path. The United States, on the other hand, is primarily seeking to prevent North Korea from gaining nuclear weapons, and has refused to engage with Pyongyang until that issue is resolved.

Other experts see a disconnect between how South Korea views its role in the region and how other nations see it. South Korean officials talk of playing a "balancing" or mediating role in regional disputes, including tensions between China and Japan and the nuclear standoff between the United States and North Korea. But South Korea's "actual ability to mediate and balance is limited," says Armstrong. And while South Korean President Roh Moo-Hyun has expressed hopes of building Seoul into a logistics and business hub for the region, existing tensions on the peninsula--including international fears that North Korea is amassing a nuclear arsenal--cloud any long-term economic plans. As things stand, South Korea has the world's 11th largest economy, but not a corresponding level of political clout.

How is South Korea dealing with North Korea?

Through a policy of active engagement. In 1998, Former President Kim Dae-Jung introduced the "Sunshine Policy" aimed at improving ties with North Korea while assuring Pyongyang that Seoul is not trying to absorb it. Since then, "the degree of economic interaction between south and north has substantially increased," Armstrong says. Kim and North Korean President Kim Jung-Il met at a historic summit in 2000, and increasing progress has been made on a range of issues, from economic--increased rail links and joint projects like the Gaesung industrial complex--to social and symbolic, including cross-border family visits and Korean athletes marching together under a single flag at the Olympics. Trade between the two countries reached $697 million in 2004, and South Korea is now Pyongyang's second-largest trading partner after China.

South Korea sees engagement with North Korea as yielding far more benefits than confrontation. "South Korea is reorienting itself toward reconciliation and eventual reunification of the peninsula," Gregg says. South Korean officials say reunification would reduce the burden on each side of maintaining huge armies, help improve living standards, draw international investment, create employment, and help avert the worst possibility: open war on the Korean peninsula.

What is South Korea's relationship with China?

South Korea is developing increasingly warm relations with its giant western neighbor. "There is a real fascination with China in South Korea, and the flow of investment, exports, students, tourists, and businessmen going to China from South Korea has exploded in the last several years," Armstrong says. Bilateral trade between Seoul and Beijing reached $90 billion in 2004, a 42 percent increase from 2003. The two countries also agree politically on issues ranging from opposition to Japanese Prime Minister Junichiro Koizumi's visits to the Yasukuni war shrine, to accord on how to deal with North Korea's nuclear ambitions. China is also choosing the path of engagement with North Korea, and helping Pyongyang find a "Chinese way" to develop: that is, increasing economic openness without sacrificing political control. "On the whole, [South Korea and China] see pretty much eye to eye on the major geopolitical issues," Kang says.

Beijing, like Seoul, is investing in North Korea, which has ample natural resources--including coal, iron, and gold--and a low-cost labor force. In 2003, Chinese investment in North Korea was $1.1 million; in 2004, it ballooned to $50 million; and in 2005, it was expected to reach $85-90 million. The volume of trade between China and North Korea reached $1.5 billion in 2005, making Beijing Pyongyang's largest foreign trading partner. North Korean leader Kim Jung-Il, who rarely travels, emphasized Beijing's importance to his country by visiting China in January.

South Korea is positioning itself to be closer to an ascendant China, but trying to do it without jeopardizing existing ties with the United States. South Korea's biggest worry, experts say, is being pulled into a conflict between the United States and China over Taiwan.

What's the relationship like between South Korea and Japan?

"Very bad at the moment in terms of public diplomacy and popular opinion," Columbia University's Armstrong says. South Korean wariness of Japan dates back at least to 1910, when imperial Japan invaded Korea and ruled it as a colony for thirty-five years. During the occupation, Japanese efforts to suppress Korean language and culture earned Korean enmity. During World War II, the Japanese practice of using "comfort women"--women from occupied countries, mostly Korea, who were forced to serve as prostitutes for the Japanese army--increased the anti-Japanese feeling.

South Koreans, and others across the region, are also infuriated by Koizumi's annual visit to the Yasukuni shrine. The site honors more than two million Japanese war dead, but includes the remains of more than a dozen convicted war criminals. South Korea also has disputes with Japan over territory. Both countries claim a group of islands--and the fishing and mineral rights around them--in the Sea of Japan that the Koreans call Dokdo and the Japanese call Takeshima. And many critics in South Korea and across Asia accuse Japan of whitewashing its wartime atrocities in its grade-school textbooks.

But much of the South Korean conflict with Japan may be for domestic political consumption, some experts say. "Under the surface, I would say the degree of interaction [between Seoul and Tokyo] remains high and, in the economic realm, is rather good," Armstrong says.

How is South Korea dealing with the United States?

While experts say most South Koreans still consider the U.S.-Korean alliance the backbone of their security relationship, time has passed and attitudes are shifting. A new generation of South Koreans, assertive and nationalistic, are less mindful of the Korean War--and less grateful for American intervention in the conflict that left nearly three million Koreans dead or wounded--and more resistant to what they see as a U.S. attempt to impose its values and Washington's singular focus on terrorism. The United States has opposed South Korean engagement efforts with North Korea, and has also moved to increase its ties with Japan. The Bush administration's foreign policy, including the war on terror, its punitive stance toward North Korean nuclear weapons, and particularly the invasion of Iraq, is highly unpopular in South Korea, according to opinion surveys there.

South Koreans are also increasingly demanding more control over their country's military and political affairs. In 2004, the United States returned several military bases to Korean control, and agreed to withdraw 12,500 of the 37,500 U.S. troops currently stationed in Korea by 2008. U.S. officials, including Defense Secretary Donald Rumsfeld, had been pushing for South Korea to take more of a role in the defense of the Korean peninsula, to free up U.S. forces for deployment elsewhere. But, all differences aside, Seoul is still eager to cooperate with the United States. South Korea, with some 3,000 troops in Iraq, is the third-largest member of the U.S.-led coalition there, behind the United States and Britain.

What is the recent history of the region?

Poised between China and Japan, fought over by the United States and Russia, the Korean peninsula long has played a central role in Asia's geopolitical affairs. After World War II, Japanese colonial rule gave way to U.S. and Soviet trusteeship over the southern and northern halves of Korea, respectively. The peninsula was divided at the 38th Parallel. In 1948, the southern Republic of Korea and the northern Democratic People's Republic of Korea, under Kim Il-Sung, were established.

In 1950, North Korean forces invaded South Korea, starting a conflict that brought in China on the North Korean side and a U.S.-led UN coalition on the South Korean side. While an armistice was agreed to in 1953, a formal peace treaty was never signed. In 1954, the United States agreed to help South Korea defend itself against external aggression in a mutual defense treaty. U.S. troops have been stationed in Korea since then. In addition to this important security relationship, shared interests in the last fifty years have included fighting communism and, since the 1980s, establishing a strong democracy and fostering economic development. However, in recent years strain has emerged on a range of issues, none more important than how to handle Pyongyang.
