This past autumn, the Freeman Spogli Institute ( 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 Stanford’s new Woods 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 Center for Environmental Science and Policy (CESP) co-director Walter P. Falcon, FSE aims to design new approaches to solve these persistent problems, expand higher education on food security and the environment at Stanford, and provide direct policy outreach.

Productive food systems and their environmental consequences form the core of the program. Fundamentally, the FSE program 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. 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 Ministries of Agriculture, Planning, and 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 Mooney, CESP senior fellow and an author of the Millennium Ecosystem Assessment. As a result, land once used to provide grains for humans now provides feed for hogs and poultry.

These trends will have major consequences for 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 analyzing the impact of intensive livestock production and assessing the environmental effects 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."

Factors contributing to the global growth of livestock systems, lead author Naylor notes, are declining feed-grain prices, relatively inexpensive transportation costs, and trade liberalization. “But many of the true costs remain largely unaccounted for,” she says, including destruction of forests and grasslands to provide farmland for feed crops destined not 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 hidden costs of 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 and expansive. Building on existing research at Stanford, researchers are identifying avenues in the world’s least developed countries to enhance orphan crop production— crops with little international trade and investment, but high local value for food and nutrition security. This work seeks to identify advanced genetic and genomic strategies, and natural resource management initiatives, to improve orphan crop yields, enhance crop diversity, and increase rural incomes through orphan crop production.

Another priority research area is development of biofuels. As countries seek energy self-reliance and look for alternatives to food and feed subsidies under World Trade Organization (WTO) 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 high crude oil prices 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 research activities. One project links ongoing research at Stanford on the environmental and resource costs of industrial livestock production and trade to assess the extent 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. An interdisciplinary team will examine strategies 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 new Presidential Fund,” 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.”

The Bill & Melinda Gates Foundation’s Agricultural Development Program has awarded Stanford University’s Program on Food Security and the Environment (FSE) and a team of collaborators $3.8 million over three years to conduct a quantitative assessment of the effect of biofuels expansion on food security in the developing world. This work will determine how different scenarios of expanded biofuels production in rich and poor countries will affect global and regional food prices, farmer incomes, and food consumption of the poor. In three case-study countries (India, Mozambique, Senegal), it will make a more detailed assessment of the opportunities and pitfalls associated with an array of possible biofuels development scenarios (e.g., using different crops for biofuels production, using marginal land versus highly productive land, etc.). We expect the work will represent the first systematic, detailed effort to address the effects of biofuels expansion on welfare in poor countries and the first available analytic tool for assessing possible biofuels investments in individual developing countries. Project collaborators include FSE, the International Food Policy Research Institute, the Center on Chinese Agricultural Policy, and the University of Nebraska.

Through this grant, the Bill & Melinda Gates Foundation aims to assess how biofuels may affect smallholder farmers in the developing world. This includes assessing both the risks, such as increasing food prices, and the potential opportunities for smallholder farmers to leverage biofuels to boost their productivity, increase their incomes, and build better lives for themselves and their families. The foundation and Stanford University will disseminate the findings widely to inform a broad audience, including policymakers.

FSE is also very pleased to announce a private gift from Lawrence Kemp for further work in the biofuels area. The Kemp gift will be devoted to building a team of faculty and students on campus who will analyze the transmission of global price effects to local markets, provide policy advice and communication on biofuels, and expand the field-level coverage of Stanford’s biofuels work.

In the November 2007 issue of Environment, project collaborators Rosamond L. Naylor (FSE), Adam Liska, Marshall Burke (FSE), Walter P. Falcon (FSE), Joanne Gaskell, Scott Rozelle (FSE), and Kenneth Cassman demonstrate how high energy prices and biofuelspromoting agricultural policy result in higher food prices generally and then examine in detail the potential global effects of biofuels expansion in four countries for four crops—corn in the United States, cassava in China, sugarcane and soy in Brazil, and palm oil in Indonesia. They argue that in each case, the threats to global food security from biofuels expansion likely outweigh the benefits, especially in the short run. This is because in many poor countries these crops play an important role in the diets of the poor and because the poorest in the world typically spend more money on food than they earn in income through farming. They also note that “second generation” technologies such as cellulosic biofuels will likely not play a significant role in biofuels production over the next decade or longer—and thus in the near-term are very unlikely to be the win-win that their proponents suggest. “The ripple effect: biofuels, food security, and the environment” excerpted from Environment, November 2007

The integration of the agricultural and energy sectors caused by rapid growth in the biofuels market signals a new era in food policy and sustainable development. For the first time in decades, agricultural commodity markets could experience a sustained increase in prices, breaking the long-term price decline that has benefited food consumers worldwide. Whether this transition occurs—and how it will affect global hunger and poverty—remain to be seen. Will food markets begin to track the volatile energy market in terms of price and availability? Will changes in agricultural commodity markets benefit net food producers and raise farm income in poor countries? How will biofuels-induced changes in agricultural commodity markets affect net consumers of food? At risk are more than 800 million food-insecure people—mostly in rural areas and dependent to some extent on agriculture for incomes— who live on less than $1 per day and spend the majority of their incomes on food. An additional 2–2.5 billion people living on $1 to $2 per day are also at risk, as rising commodity prices could pull them swiftly into a food-insecure state.

The potential impact of a large global expansion of biofuels production capacity on net food producers and consumers in low-income countries presents challenges for food policy planners and raises the question of whether sustainable development targets at a more general level can be reached. Achieving the 2015 Millennium Development Goals adopted by the United Nations General Assembly in 2000, which include halving the world’s undernourished and impoverished, lies at the core of global initiatives to improve human well-being and equity, yet today virtually no progress has been made toward achieving the dual goals of alleviating global hunger and poverty. The record varies on a regional basis: Gains have been made in many Asia-Pacific and Latin American-Caribbean countries, but progress has been mixed in South Asia and setbacks have occurred in numerous sub-Saharan African countries. Whether the biofuels boom will move extremely poor countries closer to or further from the Millennium Development Goals remains uncertain.

Biofuels growth also will influence efforts to meet two sets of longer-run development targets. The first encompasses the goals of a “sustainability transition,” articulated by the Board on Sustainable Development of the U.S. National Academy of Sciences, which seeks to provide energy, materials, and information to meet the needs of a global population of 8–10 billion by 2050, while reducing hunger and poverty and preserving the planet’s environmental life-support systems. The second is the Great Transition of the Global Scenario Group, convened by the Stockholm Environment Institute, which focuses specifically on reductions in hunger and greenhouse gas (GHG) emissions beyond 2050. As additional demands are placed on the agricultural resource base for fuel production, will ecosystem services (such as hydrologic balances, biodiversity, and soil quality) that support agricultural activities be eroded? Will biofuels development require a large expansion of crop area, which would involve conversion of marginal land, rainforest, and wetlands to arable land? And what will be the net effect of biofuels expansion on global climate change?

Although the questions outnumber the answers at this stage, two trends seem clear: Total energy use will continue to escalate as incomes rise in both industrial and developing countries, and biofuels will remain a critical energy development target in many parts of the world if petroleum prices exceed $55–$60 per barrel. Even if petroleum prices dip, policy support for biofuels as a means of boosting rural incomes in several key countries will likely generate continued expansion of biofuels production capacity. These trends will have widespread ripple effects on food security—defined here as the ability of all people at all times to have access to affordable food and nutrition for a healthy lifestyle—and on the environment at local, regional, and global scales. The ripple effects will be either positive or negative depending on the country in question and the policies in play.

FSE is excited to welcome Peter Timmer as FSE Visiting Professor. Prior to joining FSE, Timmer was a resident fellow at the Center for Global Development in Washington, and prior to that, Dean of the Graduate School of International Relations and Pacific Studies at UC San Diego. Timmer has also held professorships at Harvard, Cornell, and Stanford. In 1992, he received the Bintang Jasa Utama (Highest Merit Star) from the Republic of Indonesia for his contributions to food security. He served as the chief outside advisor to USAID in developing their strategy on growth and agriculture for the Natsios Report (Foreign Assistance in the National Interest), and was one of the key advisors for the World Development Report 2008: Agriculture for Development. Timmer's work focuses on three broad topics: the nature of "pro-poor growth" and its application in Indonesia and other countries in Asia; the supermarket revolution in developing countries and its impact on the poor (both producers and consumers); and the structural transformation in historical perspective as a framework for understanding the political economy of agricultural policy.

A new study published May 8th in the Proceedings of the National Academy of Sciences (PNAS) finds that Indonesian rice agriculture is greatly affected by short-run climate variability, and could be significantly harmed by long-run climate change. Indonesia is the fourth most populous country in the world, one of the world's largest producers and consumers of rice, and is characterized by a population of rural poor who depend on rice agriculture for their livelihood.

"Agriculture is central to human survival, and is probably the human enterprise most vulnerable to changes in climate", notes lead author Rosamond Naylor, Director of the Program on Food Security and the Environment at Stanford. "This is particularly true in countries such as Indonesia, with large populations of rural poor. Understanding the current and future effects of changes in climate on Indonesian rice agriculture will be crucial for improving the welfare of the country's poor".

Rice growers facing shortened rainy season

The PNAS study, entitled 'Assessing the risks of climate variability and climate change for Indonesian rice agriculture', was a joint effort among a team of scientists at Stanford University, the University of Washington, and the University of Wisconsin. The study finds that rice production in Indonesia is greatly affected by year-to-year climate variability -- in particular the variability caused by El Nino/Southern Oscillation (ENSO) events in the Pacific Ocean. During a warm ENSO event (or 'El Nino'), the arrival of the monsoon rains is delayed, disrupting the planting of the main rice crop and prolonging the 'hungry season' in Indonesia. "During a bad El Nino event, farmers literally wait months before they can plant their crop, resulting in a harvest that is months late and often much smaller in size", says Naylor.

The authors then analyzed how climate change could effect rainfall and agriculture in Indonesia. Using output from 20 global climate models (GCMs), running two emissions scenarios, and tailoring the GCM projections to the complex local topography of the Indonesian archipelago, the authors found that the probability of experiencing a harmful delay in monsoon rains could more than double in some of the most important rice growing regions in Indonesia.

"Most models predict that the rains will come later in Indonesia, it will rain a little harder once the monsoon begins, and then it will really dry up during the summer months," says David Battisti, co-author and atmospheric scientist at the University of Washington. "So Indonesia could be looking at a much shorter rainy season, with an almost rainless dry season in some areas, squeezing rice farmers on both ends".

While the study cannot directly address changes in the frequency or intensity of ENSO events under future climate change -- still an area of active research -- the authors conclude that even if there were no changes in the basic pattern of ENSO, Indonesian rice growers will be facing a significantly shortened rainy season. In the absence of adaptive measures, these growers could suffer greatly.

Adapting for change

What adaptive measures could be taken in the face of harmful short-run variability and long-run change in climate? In the short run, the science of ENSO prediction has advanced to the point that reasonably high-confidence ENSO forecasts are available at least two seasons in advance. A forecasting model developed by the authors is now being used to by the Indonesian Agricultural Ministry to anticipate and plan for ENSO events and their effects on agriculture. The authors are also working with Indonesian officials to develop longer-run strategies which address the anticipated effects of climate change on agriculture in the country. Such strategies could include investments in water storage, development of drought-tolerant crops, and crop diversification for those farmers at greatest risk.

Along with its important findings for Indonesian policy-makers, the study design itself is a novel contribution to the literature. "To our knowledge, our study is the first climate-agriculture study that uses projections from all available GCMs to look at climate effects in a specific region", explains Battisti. "Thus more than past efforts, our study captures the range of uncertainty across different projections of future climate, knowledge which will be crucial for long-run thinking about how to respond."

Battisti also notes that the use of empirical downscaling models in the study, which translate GCM output into useable regional forecasts of changes in climate, is a technique missing from most other studies of climate and agriculture in the tropics, an omission that could render their regional climate projections untrustworthy. Naylor adds: "From a scientific perspective, its imperative that we now replicate this kind of study elsewhere, in order to start building a more complete picture of the effects of climate change on agriculture." The team has begun a similar study in China this spring.
