Agricultural productivity in sub-Saharan Africa remains significantly less than the rest of the world, and 25 percent of people in the region still suffer from an insufficient dietary intake of calories. Yet sub-Saharan Africa has more arable land than Asia or Latin America, and a more diverse set of cereal grains. Agriculture also accounts for 20-25 percent of GDP for the region compared with only five percent for the rest of the world.

So why is productivity in sub-Saharan Africa so low when agriculture is such a big part of the economy, asked Rosamond L. Naylor, director of the Center on Food Security Environment at last week’s Connecting the Dots conference. Lack of irrigation is part of the problem. 95 percent of farms in sub-Saharan Africa are rainfed and rely on water from a short, 4-5 month rainy season. 

“During the rainy season kids are fed pretty well,” explained Naylor. “But during the peak of the dry season up to one-third of children are severely malnourished in parts of West Africa where we have been working.”

Sub-Saharan Africa has largely missed out on the benefits of the Green Revolution that increased crop production in Asia two to three fold. Asia’s heavily irrigated agriculture took advantage of new crop varieties that were bred to take up nutrients with sufficient water availability. Groundwater sources in sub-Saharan Africa, on the other hand, are more fractured and not well understood, and surface water isn’t necessarily close to where the people are.

“But Africa has water” said Naylor. “Groundwater resources have not been sufficiently explored and rivers such as the Nile and Niger remain underutilized due to a mindset that irrigation systems must be large scale.”

This requires big investments and institutional involvement that have thus far not resulted in great payoffs. Corruption in some areas coupled with institutional and tribal issues have also contributed to failed investments.

“We need to change our investment strategies from large-scale to small-scale irrigation systems,” suggested Naylor. “Evaluate the returns from treadle, solar-power, and diesel pumps to see what works where, so that we stop investments that aren’t working and support investments where they are.”

Treadle pumps can work well if they are close to surface water, but require a lot of labor, explained Naylor. There is a huge energetic cost and an opportunity cost for someone to work the treadle pump, so it is necessary to ‘get the right technology to suit the water and labor conditions’.

Irrigation is not just about access (drawing water). It is also necessary to think about how to best distribute that water to crops (e.g. drip irrigation) and what you use them on. Production of leafy greens, for example, leads to higher income and nutritional returns.

FSE’s solar market garden project in Benin is a good example of where appropriate technologies are being applied in a cost-effective manner. Solar-powered, drip irrigation pumps have improved incomes and nutrition for participating farming groups through the year-round production of high-value crops. Proven to be a viable and profitable investment, the project is now scaling up in other villages in Benin and West Africa.

“According to the World Bank, investment in agriculture is the best bang for your buck than any other investment,” said panel moderator Jenna Davis, assistant professor in the department of civil and environmental engineering and affiliated FSE fellow.

Fortunately, the World Bank is beginning to recognize the viability and efficiency of investments in small-scale irrigation projects. NGOs and academia also have a role to play in facilitating these projects. Through these partnerships and shifts in investment strategies, the development community has a better chance of improving access to freshwater resources for some of the world’s most vulnerable and effectively addressing sub-Saharan Africa's water and food security crisis.

In the first decade of the 21^st century, global production of ethanol and biodiesel increased nearly tenfold. If that trend continues, says Rosamond L. Naylor, director of Stanford University’s Center on Food Security and the Environment, national biofuels policies will have an increasingly powerful impact on food prices, food security, energy security, and rural incomes in the developing world.

During a two-hour symposium held on the Stanford campus last Wednesday, Naylor addressed the role of biofuels in global food price volatility and the implications of biofuels development in rural Africa and Asia. Although she acknowledged that global income and population growth have contributed to increased demand for biofuels, she also emphasized “the unbelievable dominance of policy” in driving current trends.

“The main part of this that I think is so significant is the use of mandates,” Naylor said. “Policies such as the United States’ Renewable Fuels Standard (RFS), which sets a national target of using 15 billion gallons of corn-based ethanol per year by 2015, have reshaped price and supply dynamics in both food and fuel markets. “

“When you think about the fact that the US provides half of the world’s corn…the fact that we’re using so much in our gas tanks, biofuels really is changing the nature of global markets,” Naylor said. Policies that fix demand for corn from the ethanol market, she explained, have a destabilizing effect on corn prices, especially in the face of supply shortages.

“When you have mandates you have a quantity that you’re absolutely insisting you use, regardless of the price,” she said. “That inelastic demand leads to more volatile prices with supply shocks.”

Because of the substitutability of basic food commodities, Naylor said, price volatility in the corn market has far-reaching consequences. “Prices of corn ripple through all of the world food economy markets…it affects the demand and supply of wheat and rice and soy, and other things,” she explained. And for poor households in the developing world, she said, “it has big income effects…when you’re spending 70 to 80 percent of your budget on food, you’re going to be hurt the most.”

However, Naylor also noted that biofuel mandates in the developed world could provide valuable market opportunities for developing-country farmers.

In rural Africa and Asia, she said, farmers “see the US having a big mandate, EU having a big mandate, and they think, can they supply into that mandated need?”

For now, it seems, the answer is “maybe.” In Africa, for example, efforts are underway to increase the use of jatropha – an inedible, drought-resistant shrub – as a biofuel feedstock. But Naylor said that low yields and high labor costs are likely to severely limit the economic returns from jatropha-based biofuels.

And in marginal growing conditions, the use of more conventional feedstocks is often restricted by resource availability. In India, for example, where almost all sugarcane is grown under irrigated conditions, expansion of sugarcane area to supply the ethanol market could lead to water shortages. Even if these countries can make large-scale biofuel production economically viable, the benefits to poor farmers could vary widely depending on the structure of the market.

“The implications of biofuel development are going to be quite different,” Naylor said, “depending on the organization of the value chain.”

Dr. Siwa Msangi, a Senior Research Fellow with the International Food Policy Research Institute, agreed. In comments following Naylor’s presentation, Msangi said biofuel development contributes most effectively to rural income growth “when you can have vertical integration…people all along the value chain have to be making money.”

Msangi also noted that commodity price increases, including those driven by ethanol mandates, could benefit small farmers if they are controlled and predictable. “Sharp, fast, sudden price rises – those are the ones that are bad for consumers,” he explained. But prices rises “can be positive…especially if those price rises can be gradual and sustained over time, because that gives people the opportunity to mobilize resources to make use of higher returns.” For example, small farmers at the local or national level can increase their production of crops in high demand for biofuel production.

The emerging connections between agriculture and energy markets are complex, Msangi said, but can be advantageous if handled carefully. “If there are good opportunities for agribusiness, I think there’s a case for taking them,” he said, “but also for being aware of the context and all the issues.”

This was the eighth talk in FSE’s Global Food Policy and Food Security Symposium Series. 

Philanthropist and software giant Bill Gates spoke to a Stanford audience last week about the importance of foreign aid and product innovation in the fight against chronic hunger, poverty and disease in the developing world.

His message goes hand-in-hand with the ongoing work of researchers at Stanford’s Freeman Spogli Institute for International Studies. Much of that work is supported by FSI’s Global Underdevelopment Action Fund, which provides seed grants to help faculty members design research experiments and conduct fieldwork in some of the world’s poorest places.

Four FSI senior fellows – Larry Diamond, Jeremy Weinstein, Paul Wise and Walter Falcon – respond to some of the points made by Gates and share insight into their own research and ideas about how to advance and secure the most fragile nations.

Without first improving people’s health, Gates says it’s harder to build good governance and reliable infrastructure in a developing country. Is that the best way to prioritize when thinking about foreign aid?

Larry Diamond: I have immense admiration for what Bill Gates is doing to reduce childhood and maternal fatality and improve the quality of life in poor countries.  He is literally saving millions of lives.  But in two respects (at least), it's misguided to think that public health should come "before" improvements in governance.  

First, there is no reason why we need to choose, or why the two types of interventions should be in conflict.  People need vaccines against endemic and preventable diseases – and they need institutional reforms to strengthen societal resistance to corruption, a sociopolitical disease that drains society of the energy and resources to fight poverty, ignorance, and disease.  

Second, good governance is a vital facilitator of improved public health.  When corruption is controlled, public resources are used efficiently and justly to build modern sanitation and transportation systems, and to train and operate modern health care systems.  With good, accountable governance, public health and life expectancy improve much more dramatically.  When corruption is endemic, life-saving vaccines, drugs, and treatments too often fall beyond the reach of poor people who cannot make under-the-table payments. 

Foreign aid has come under criticism for not being effective, and most countries have very small foreign aid budgets. How do you make the case that foreign aid is a worthy investment?

Jeremy M. Weinstein: While foreign aid may be a small part of most countries’ national budgets, global development assistance has increased markedly in the past 50 years. Between 2000 and 2010, global aid increased from $78 billion to nearly $130 billion – and the U.S. continues to be the world’s leading donor.

The challenge in the next decade will be to sustain high aid volumes given the economic challenges that now confront developed countries. I am confident that we can and will sustain these volumes for three reasons.

First, a strong core of leading voices in both parties recognizes that promoting development serves our national interest. In this interconnected world, our security and prosperity depend in important ways on the security and prosperity of those who live beyond our borders.

Second, providing assistance is a reflection of our values – it is these humanitarian motives that drove the unprecedented U.S. commitment to fighting HIV/AIDS during the Bush Administration.

Perhaps most importantly, especially in tight budget times, development agencies are learning a great deal about what works in foreign assistance, and are putting taxpayers’ dollars to better use to reduce poverty, fight disease, increase productivity, and strengthen governance – with increasing evidence to show for it.

Some of the most dire situations in the developing world are found in conflict zones. How can philanthropists and nongovernmental organizations best work in places with unstable governments and public health crises? Is there a role for larger groups like the Gates Foundation to play in war-torn areas?

Paul H. Wise: As a pediatrician, the central challenge is this: The majority of preventable child deaths in Sub-Saharan Africa and in much of the world occur in areas of political instability and poor governance. 

This means that if we are to make real progress in improving child health we must be able to enhance the provision of critical, highly efficacious health interventions in areas that are characterized by complex political environments – often where corruption, civil conflict, and poor public management are the rule. 

Currently, most of the major global health funders tend to avoid working in such areas, as they would rather invest their efforts and resources in supportive, well-functioning locations.  This is understandable. However, given where the preventable deaths are occurring, it is not acceptable. 

Our efforts are directed at creating new strategies capable of bringing essential services to unstable regions of the world.  This will require new collaborations between health professionals, global security experts, political scientists, and management specialists in order to craft integrated child health strategies that respect both the technical requirements of critical health services and the political and management innovations that will ensure that these life-saving interventions reach all children in need.

Gates says innovation is essential to improving agricultural production for small farmers in the poorest places. What is the most-needed invention or idea that needs to be put into place to fight global hunger?

Walter P. Falcon: No single innovation will end hunger, but widespread use of cell phone technology could help.

Most poor agricultural communities receive few benefits from agricultural extension services, many of which were decimated during earlier periods of structural reform. But small farmers often have cell phones or live in villages where phones are present.

My priority innovation is for a  $10 smart phone, to be complemented with a series of very specific applications designed for transferring knowledge about new agricultural technologies to particular regions.  Using the wiki-like potential of these applications, it would also be possible for farmers from different villages to teach each other, share critical local knowledge, and also interact with crop and livestock specialists.

Language and visual qualities of the applications would be key, and literacy problems would be constraining.  But the potential payoff seems enormous.

Rosamond L. Naylor, director of the Center on Food Security and the Environment, will join demographers, authors, activists, economists, and scientists for a daylong symposium on population at the Moving Mountains Symposium in Telluride May 25. During the daylong symposium speakers will touch on subjects like water tables, food security, women's education, immigration, and human longevity in the context of population growth.

Clip from Telluride Daily Planet:

FSE director Roz Naylor will address the challenges of feeding the growing world. According to Naylor, humans are already pushing against the limits of high yield agriculture, fisheries and habitat displacement for farming to feed a population that is trending toward a more carnivorous, and therefore higher impact, diet.

“Part of the focus is: How do we meet future demands of so many people on the planet? Another important question is, if we are successful, does it just promote and enable population growth?” she said, or does it set the stage for a population to level out.

Feeding the world goes back to agriculture and food production but also biofuels, and it will require new technologies and interdisciplinary collaboration, Naylor said.

Other participants include Stanford's Paul Ehrlich, author of “The Population Bomb” and long-time leading voice on the population issue, who will talk about what will happen when the population bomb explodes. 

Stanford opened a research and education center at China’s Peking University, strengthening an already close academic bond and building a stronger tie to one of the world’s fastest-growing countries.

“Globalization is the defining characteristic of the 21^st Century,” Stanford President John Hennessy said during an opening ceremony on March 21 that drew hundreds of academics, donors and government officials to the opening of the Stanford Center at Peking University.

“It is increasingly important for our students to understand what it means to be citizens of the world, to bring a more international perspective, to be able to communicate with others from different backgrounds or with different expertise,” he said. “Both Peking University and Stanford are stepping up to that challenge and moving to become more global institutions to address the challenges of this century. This new center exemplifies that.”

Designed as a resource for the entire Stanford community and administered by the university’s Freeman Spogli Institute for International Studies, 10 programs and departments – including the School of Medicine’s Asian Liver Center, the Bing Overseas Studies Program and the Rural Education Action Project – will locate operations at SCPKU.

FSI faculty already doing research in China showcased their work during conferences held in conjunction with the opening of the center.

The new building is available to the several hundred Stanford scholars studying, researching and conducting university activities in China each year. It also offers the opportunity for Stanford faculty to work with academics from Peking University and other universities throughout China.

“Stanford is one of the most valued partners of Peking University,” PKU President Zhou Qifeng said. “The center will create more opportunities through collaborative research, student and faculty exchange programs, joint teaching and other activities.”

The center makes Stanford the first American university to construct a building for its use on a major Chinese university campus. SCPKU will allow current educational programs to expand, but will not grant Stanford degrees.

The center’s distinctiveness is reflected in the building that houses it – a 36,000-square-foot structure that combines Chinese and Western architecture. The courtyard building was constructed with interlocking mortise-and-tenon joinery – a classic Chinese technique that eliminates the need for nails or glue.

Hand-painted scenes depicting typical Chinese landscapes and views from Stanford’s campus are featured on the building beams. At the point where beams and columns meet, artists added Chinese symbols for teaching, learning and scholarship.

State-of-the-art classrooms, conference rooms and meeting spaces fill out the two floors below the courtyard. Skylights, interior gardens and a reflecting pool invoke a natural setting.

The melding of styles brings as much substance as symbolism.

SCPKU “marks a new era of collaboration between two outstanding universities,” Gary Locke, the U.S. ambassador to China, said during the opening ceremony. “It also represents a new bridge of understanding between our nations – and most importantly – our peoples.

“There are virtually no problems in the world today that cannot be solved if the people – the scientists and engineers, and the business people – of the United States and China join together,” Locke said. “And this center will help make that happen.”

Stanford’s relationship with China dates to the late 1970s, when the university began accepting Chinese graduate students. Students from China have accounted for the largest number of Stanford’s foreign graduate students for the past decade, with about 600 enrolled last year.

Those scholars are part of the 160,000 Chinese students studying in American colleges and universities every year, a number that eclipses the 16,000 American students taking classes in China, Locke said.

“We have to know much more about each other’s cultures, customs, traditions, values and languages so we can build a mutual trust and understanding that will allow us to face all of the challenges we face,” he said. “The way to build that trust starts with building people-to-people interactions. It starts with more student exchanges…and it most certainly starts with the Stanford center here at Peking University.”

Over the last 30 years, Stanford’s bond with Peking University has grown from an initial collaboration between the schools’ Asian language departments to a wide range of joint research and academic exchanges.

In 2004, Stanford’s undergraduate study abroad and internship programs began at Peking University. The study abroad program continues to be managed by the Bing Overseas Studies Program, which hosts roughly 60 undergraduates every year on the Peking University campus.  The internship programs are coordinated by the International, Comparative, and Area Studies Program.

The overseas studies program offers a broad curriculum taught by a Stanford faculty-in-residence who spends a 10-week quarter with the students in Beijing.  A range of topical and language courses are taught by Peking University faculty.

“The new center at PKU allows us to continue this dynamic program in a new environment designed to encourage interaction across disciplines and with graduate students and faculty from both universities,” said Irene Kennedy, the program’s executive director. “We also plan to continue supporting and developing interactions between Stanford and PKU students through language partnering and by including Chinese students in classes taught by Stanford faculty and associated field trips.”

Jean Oi and Andrew Walder – both senior fellows at the Freeman Spogli Institute – began building on that relationship in 2006 by envisioning a way to bolster Stanford research, teaching, training and outreach activities in China. Their ideas led to the creation of SCPKU and several new academic programs, including a law school exchange program.

The $7 million project is funded entirely from gifts made to the Stanford International Initiative. The lead donor was the charitable foundation of the family of Chien Lee, a Hong Kong-based private investor and Stanford emeritus trustee who received his bachelor's and master's degrees from the university in 1975 and his MBA from the Graduate School of Business four years later.

The SCPKU building is named for his father, the late Lee Jung Sen, who attended Peking University in the mid-1930s when it was Yenching University. Lee’s mother, Leatrice Lowe Lee, graduated from Stanford in 1945.

A bust of Lee Jung Sen sits in SCPKU’s courtyard, one level above the modern facility and surrounded by the more familiar, traditional Chinese architecture.
