Transgenics fast growing adoption

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

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

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

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

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

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

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

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.

Harmonization of labeling policies

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

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

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

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.
