Crude oil prices hit $120 a barrel this month, translating into gas pump prices above $4 a gallon in parts of the United States. As a result, the rallying cry of energy self-sufficiency is gaining strength, reinforcing the U.S. policy of promoting renewable fuels, particularly corn-based ethanol, to reduce dependence on imported oil.

But a different rallying cry—food self-sufficiency—is becoming louder in many developing countries where rice, wheat and other staples are in such short supply that food riots have erupted. China, India, Argentina and several other countries have raised export restrictions on key crops to ensure food supplies for their consumers. That move has further increased world prices.

It is important to remember two key lessons from similar chaos in world food markets in 1973-74. First, attempts to gain domestic price stability create global price instability. And second, once policies are established to protect food markets, they are not easily dismantled. It took two decades for rice trade to expand in Asia, and even then, it remained limited.

The United States must take a lead in confronting the world food crisis. But to do so will require a genuine commitment to improving the well-being of people around the world—and recognizing that energy self-sufficiency at home can mean widespread starvation abroad.

In its starkest form, the global food crisis is about rising agricultural commodity prices that place hundreds of millions of poor people at greater risk of malnutrition. Most of the 800 million people globally who survive on a dollar a day or less live in rural areas and work on farms.

The two- to fourfold jump in prices during the past 18 months for internationally traded commodities, such as rice, wheat, corn, soy and vegetable oils, has resulted in fewer and smaller meals for the poor. The rise in the number of malnourished people globally is only beginning to be tallied.

High food prices have been associated with high petroleum prices. The cost of crop production is up, the value of the dollar is down, and biofuels are an attractive alternative to fossil fuels for transportation. Diverting one-fifth of the U.S. corn crop to corn-ethanol production and setting a renewable fuels mandate of 20 percent of U.S. motor fuel consumption by 2022— a fourfold increase in 15 years—has driven up prices for corn and substitute crops, especially soybeans.

Demand for corn, soy and other livestock feeds already had been rising due to increased meat consumption by China and other emerging economies. Add some major weather, pest and disease shocks, and the market for staple agricultural commodities tightened dramatically in 2006 and 2007.

Moreover, a surge in speculative activity has exacerbated market volatility.

How should the three presidential candidates, in particular, address this crisis?

For starters, the United States should retreat from its heavy promotion of corn-based ethanol and allow the markets to settle. Although the 2008 U.S. Farm Bill, passed by the House and Senate last week, includes a reduction in the ethanol blending credit from 51 cents to 45 cents per gallon, the subsidy remains high and is offset by other biofuels production incentives.

President Bush plans to veto the bill, but both the House and the Senate passed it with more than the two-thirds majority needed to overturn a veto. The presidential candidates, Sens. John McCain, Barack Obama and Hillary Rodham Clinton, were all absent for the vote.

The bill increases the Food Stamp Program by $10 billion to help poor Americans buy food at higher prices, but there are no measures that will assure developing countries and international markets that global food supplies will be adequate and that prices will come down. Congress needs to endorse the World Food Program's new strategy of providing food aid in the form of cash instead of surplus grain shipments, a strategy that would allow food-deficit countries to purchase their calories regionally and thereby promote agriculture closer to home.

It also would be wise for the U.S. Agency for International Development to expand, not abolish, investments in agricultural research for low-income countries.

The world can produce plenty of crops at reasonable prices for food and feed, if appropriate agricultural investments are made. But it cannot produce enough crops for food, feed and fuel at prices affordable to half of the world's population.

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."
