Should the Labeling of Genetically Modified Foods be Harmonized? A Focus on Transgenic WheatG.Gruère & C. CarterUniversity of California, DavisINEA seminar, Roma, June 20, 2003
Transgenics: Fast Growing Adoption • In 6 years, growth in biotech crop acres has been double-digit & now over 150 m. ac. > 20% of global soybeans, corn, cotton & canola acres are biotech. • US, Argentina, Canada & China are leading growers of biotech crops. • Mostly herbicide tolerant (75%) & insect resistant (17%) crops.
Importance in Developing Countries: e.g., China • > 50% of China's cotton now biotech. • Bollworm resistance to pesticides was a big problem in China before Bt. • Cotton fields were sprayed up to 40 times. • With Bt cotton, China’s farmers have saved 20% in production costs. • China’s pesticide use has fallen sharply with Bt cotton (C. Pray). • Bt cotton has potential to eliminate the need for 40% of global pesticide use (Clive James, ISAAA).
GM Wheat: Rich Country Reaction • “Hovis to stop N. America imports if GM wheat planted.” (World-Grain.com, June 5, 2003). • “E.U., U.S. millers warn against GM wheat at meeting.” (World-Grain.com, August 12, 2002) • “GM wheat 'devastating' for farmers, CWB warns” The Star Phoenix (Saskatoon), May 28, 2003. • CWB is now threatening a lawsuit against Monsanto.
Is Transgenic Wheat Different from other GMOs? • EU opposition has caught attention of US and other trading nations. • Wheat is a food grain, whereas corn, and soybeans are mainly used for feed. • Soybean, corn, & canola oil largely exempt from labeling regulations in the EU & elsewhere. • Plenty of GM food now eaten in EU, Japan, & China.
EU versus GM Technology • In WTO case, US alleges violation of Sanitary & Phytosanitary (SPS) Agreement. • Since Oct. ’98 no new GMOs have been authorized in the EU. • EU response to WTO case: “lack of consumer demand accounts for low sales of GMOs in the EU” (EU trade directorate). • EU is finalizing rules on labeling & traceability. EU trade directorate says the EU system is “science based” & not driven by economic considerations.
EU’s Parliament Environ. Committee • Labeling at 0.9% tolerance. • EU influences other countries (Isaac; Paarlberg) e.g.: Zambia, Zimbabwe, Russia & China • Lowering of adventious presence to 0.5% from 0.9%? Including soy & corn oil (whether or not detectable). • Zero tolerance level for non-authorized GMOs. • EU Parliament will consider these changes in July.
International Rules • UN food code (Codex Alimentarius) unable to reach an agreement on GM labeling. • Cartagena Biosafety Protocol: uses a "precautionary approach“& allows importers to block GM imports if they are not satisfied with information supplied by exporters. • Protocol promotes idea of letting each country decide on its own labeling policy. • US has opposed the Protocol.
Labeling • Mandatory labeling encourages food processors to switch away from GM ingredients & avoid labels, especially for highly processed products. • In the EU, Tolerant consumers suffer economic loss due to lack of choice at the retail level.
Decision to Process GM vs Non-GM Food: Mandatory vs Voluntary Labeling Non-GM to GM Profit Isoprofit Non-GM GM EU US X - • • 1.0 Y • • V Expected GM Market Share Z 0 1.0 0.5
Harmonization of Labeling Policies • Kirchoff & Zago (2001) & Jackson (2002) find that harmonization is not a good idea for the US & EU. • Labeling policies may not have a large effect on soybeans & corn (Gruère & Carter); animal feed & soy oil is (currently) exempt from labeling. • Transgenic food crops (wheat & rice) is a different story & labeling will have significant economic effect.

Wheat Studies Foster (ABARE, 2001) • AGLINK model; 10% yield boost; 1% cost increase; 10% IP cost; 60% adoption in US; world price falls by 0.4%; world consumer benefits of $2.1 B. Furtan, Gray & Holzman (UofS / USDA,’02) • Segretation infeasible; GM acceptance in US/Canada only; TUA $5/$6; if both countries license prices fall by over 75¢/bu; US farmers lose $345M & Canadians farmers lose $314M annually • Including consumers & biotech firms, net gain in US $271M but loss of $47M in Canada.
Wheat Studies Taylor, deVuyst, Koo (NDSU, 2003) • Model HRS, CWRS & HRW; TUA $4/ac; 10% yield boost; 2% cost saving; IP costs 6¢/bu; Adoption in US & Canada; EU, Japan & S. Korea buy non-GM; Canadian farmers gain $75M/yr; US farmers lose $7M (due to winter wheat losses). Wisner (Iowa State U, 2003) • US will lose 30-50% of HRS market & larger share of durum. • With dual marketing, foreign buyers would go elsewhere to avoid paying non-GM premium & alternative supplies would be readily available. Segregation costs ~45 ¢/bu.
Simulation World Wheat Model • 3 Regions (A& B are rich & C is poor). • Precautionary consumers: 20%(A); 90% (B); 5%(C). • Segregation costs 10%. • Regions linked by trade. • Model calibrated to current Supply & Demand. • Produce 75% GM in region A & 50% in region C. • Does Harmonization make sense?

Conclusions • In the case of corn or soybeans, harmonization of labeling policies may not be so important. • However, in the case of food crops, large country labeling policies have significant market impacts. • Current labeling regulations are not a first-best policy & there are benefits from harmonization. • Large gains in developing countries.
