THE CULTURE WAR OVER FOOD AND FARMING: WHO IS WINNING?
Robert [email protected]
University of WisconsinApril 20, 2012
FUNDAMENTAL DISAGREEMENTS
• Over what farms should look like
• Over the most important challenge to farming
• Over farming’s proper relationship to nature
• Over who should make decisions about food and agriculture
ADVOCATES FOR CONVENTIONAL AGRICULTURE
ADVOCATES FOR ALTERNATIVE AGRICULTURE
Large, specialized farms are OK.
Large, specialized farms are not OK.
WHAT FARMS SHOULD LOOK LIKE
ADVOCATES FOR CONVENTIONAL AGRICULTURE
ADVOCATES FOR ALTERNATIVE AGRICULTURE
Produce much more food by 2050
Preserve traditional rural livelihoods, protect biodiversity, and provide ecosystem services.
THE MOST IMPORTANT CHALLENGE TO FARMING
ADVOCATES FOR CONVENTIONAL AGRICULTURE
ADVOCATES FOR ALTERNATIVE AGRICULTURE
Protect nature by generating high yields, to reduce the area being cropped.
The best systems are those that imitate nature.
FARMING’S PROPER RELATIONSHIP TO NATURE
ADVOCATES FOR CONVENTIONAL AGRICULTURE
ADVOCATES FOR ALTERNATIVE AGRICULTURE
Governments, technical experts, and the market.
Governments, experts, and markets are not to be trusted.
WHO SHOULD MAKE DECISIONS ABOUT AGRICULTURE?
THE CAMP SYMPATHETIC TO CONVENTIONAL AGRICULTURE
THE CAMP SYMPATHETIC TO ALTERNATIVE AGRICULTURE
•Commercial Farmers•Agribusiness Companies•Ag Committees of Cong.•Scientists•Economists
• Environmental advocates• Social justice advocates• Anti-corporate activists• Anti-globalization activists• Cultural elites
THE OPPOSING CAMPS
ALTERNATIVE AGRICULTURE DOMINATES THE CULTURAL MARKETPLACE:
LOCAL FOOD: OUTCOMES IN COMMERCIAL MARKETPLACE
• Number of farmers markets in US has doubled since 1998
• Number of CSA’s has risen from 400 in 2001 to at least 4000 today
• Even so, food sales through farmers markets and CSA’s make up only 4/10 of 1% of all agricultural sales in the United States
ORGANIC FOOD: OUTCOMES IN COMMERCIAL MARKETPLACE
• In 2010, only 4% of food sales organic
• Only 7% of these organic food sales took place at farmers’ markets
• 45% of organic production in just two states, with large, specialized farms
Harvested Organic Cropland in 2008 was 0.51% of the US Total Cropland

SUSTAINABILITY GAINS FROM MODERN FARMING IN OECD COUNTRIES, 1990-2004
POST-1980 EMERGENCE OF “PRECISION” CROP FARMING
• More precise irrigation techniques
• More precise fertilizer use
• Reduced pesticide use
• Reduced tillage, saving diesel fuel

REDUCING PESTICIDE USE
• Since 1972, U.S. ban on organochlorine insecticides
• Since 1990s, variable rate application
• Since 1996 introduction of Bt corn and Bt cotton (reducing insecticide use)
• Since 1996 introduction of glyphosate-resistant soybeans (replacing herbicides that are more toxic to animals)
Bt Corn: Protection Against Corn Borer
2010 REPORT FROM EU COMMISSION DIRECTORATE-GENERAL FOR RESEARCH:
"The main conclusion to be drawn from the efforts of more than 130 research projects, covering a period of more than 25 years of research, and involving more than 500 independent research groups, is that biotechnology, and in particular GMOs, are not per se more risky than, for example, conventional plant breeding technologies."
REDUCED TILLAGE AND CULTIVATION TO SAVE SOIL AND DIESEL FUEL
• 1980s: Machines that seed unplowed fields
• 1990s: Glyphosate-resistant crops that allow reduced mechanical cultivation

LIVESTOCK FARMING:A SEPARATE ISSUE?
CAFOS
LIVESTOCK FARMING
CAFOs work well for:• Reducing costs to consumers• Reducing the frequency of food contamination
CAFOs work less well for:• Waste disposal• Dependence on antibiotics• Animal welfare
LEGAL, POLITICAL, AND COMMERCIAL ENVIRONMENT INCREASINGLY HOSTILE TO CAFOs
• Court and FDA actions against growth promotion use of antibiotics
• State level bans on gestation crates and small cage space for hens
• Voluntary phase-outs of pork from sow crates by Hormel, Smithfield Foods, Whole Foods, Chipolte, McDonald’s
• Alternative agriculture has recently become dominant in the elite cultural marketplace.
• Conventional crop farming has given up none of its dominance in the commercial marketplace.
• Conventional livestock farming is being forced to accept new restraints from the commercial and political marketplace.
CONCLUSION:WHO IS WINNING?
