Five major conclusions about the experience with
GM cropsFour guesses about the future
directions and issues regarding GM crops
3
Conclusion 1
Both proponents and opponents of Gm crops tend to
want to portray all of them as being
fundamentally of the same type or class. But GM
crops (as commonly understood, i.e., as crop
varieties that involve single-transgene input
traits) are not all of a piece, and their
socioeconomic implications are highly
crop-specific and are often location-specific in
their environmental and social implications a
well. Biotechnology ought not to be evaluated as
good or bad as a class, but rather on a
technology-by-technology basic (often taking into
account interactions with social and natural
environment).

GM crops are a very particular technology
  • Single-gene traits
  • Two input traits Bt (insect resistance) and HR
    (herbicide resistance/tolerance)
  • Transgenic
  • A very few crops soybeans, corn, cotton, and
    canola
  • Some failures Bt potatoes, FLAVR-SAVR Tomato
  • Eventually wheat?

5
Advanced or modern biology includes GM crop
technologies, but is a much larger and
heterogeneous set of tools. Genomics, bioinform
atics, and computational molecular biology
For example, Susan McCouch, Professor of Plant B
reeding, Cornell University, and rice genomics

Genes That Greatly Boost Rice Yields Are
Identified by Cornell Researchers
Thanks to a technique known as genetic mapping,
Cornell University scientists have, for the first
time, located genetic factors that allow
significant increases in yields of rice grown by
poor farmers trying to produce crops in
hardscrabble conditions. The researchers' brea
kthrough has been to use genetic maps to identify
regions of chromosomes containing genes that
control traits such as grains per plant, disease
resistance, and earliness. These genes are
identified in a wild ancestor of rice and then
introgressed, or "spliced," into domesticated,
popular varieties of rice. In this case, the
genes were introduced into a variety of upland
rice, widely grown in unfavorable conditions such
as on mountain slopes. As a result, the yield of
the domesticated rice has been increased.
7
"The ability to use modern molecular techniques
to improve yield and disease resistance of
varieties grown by poor farmers under adverse
conditions is as important as using this
technology in the high-production areas of the
world," says Susan R. McCouch, Cornell assistant
professor of plant breeding. McCouch presented
the results of this plant-breeding achievement at
the annual meeting of the American Association
for the Advancement of Science. Her talk,
"Molecular Breeding and Genetic Resources," was
part of a panel discussion on "Accelerating Crop
Evolution for Greater Production and Better
Biodiversity Conservation." For more

Conclusion 2
The tendency is for GM crops to be adopted by
farmers in spite of, rather than because of,
their profitability performance.
For most crops and most farmers, GM varieties te
nd to be somewhat better than a break-even
proposition (with nearly half of adopters
reporting that they either lead to no increase,
or even a decrease, in net profiteers per acre).
But these crops are still attractive to many
farmers. Why?

13
Conclusion 3
The major attraction of GM crops, especially the
most successful ones (HR soybeans and Bt cotton),
is that they substitute for management and make
management decision-making more routine.
14
Conclusion 4
In the US context at least, GM crops have tended
to be somewhat more widely adopted by larger
farmers than by smaller ones, but the
scale-bias of GM crops is much less than for
may new technologies such as rBST or precision
farming). One of the ironies of the adoption a
nd diffusion of GM crops is that, at a food
system or food supply levels, foods with GM
ingredients have diffused rapidly, whereas at the
farm level and from a geographical perspective
there is very little use of GM crops across the
world.
15
Conclusion 4 (continued)
GM opponents are alarmed at the spread of GM
ingredients in so many foods at the retail level.
GM proponents views are less singular, or are
contradictory in some fora the rapid spread of
GM crops is trumpeted, while in other for a
concern is expressed that regulatory roadblocks
and inappropriate public attitudes are needlessly
getting in the way of needed improvements in crop
production.

Conclusion 5
Outside of the US, Canada and Argentina, there is
relatively little GM crop acreage in the world.
About 65 percent of the total GM crop acreage in
2001 was accounted for by one technology (HR
soybeans) in one country (the US). Yet, much of
the rhetoric, and a good share of the activity,
associated with GM crops is now focused on the
developing countries. Why?

Prediction/Guess 1
  • The US and European Union (plus East Asia and
    Oceania) are probably at a stalemate over
    approval and regulation of GM crops.
  • As the US has become increasingly convinced that
    the Europeans are hopeless, and as the
    Europeans have become increasingly convinced that
    the Americans are hopeless, each of the two
    major sides to the GM crop controversy has
    shifted its attention to the developing world.

22
Prediction/Guess 1
  • Both Europe and the US are increasing their
    efforts to influence developing county leaders,
    scientists, and farmers to adopt their views on
    GM crops.
  • Ultimately what is most at stake is the integrity
    of opposing regulatory institutions and cultures
    (the precautionary principle in the EU, and
    substantial equivalence and cost-benefit-type
    risk assessment in the US).

23
Prediction/Guess 2
  • Do not be surprised if Transatlantic and other
    global conflicts over GM crops, and over
    agricultural policy, lead to a rollback of some
    of the provisions of the mid-1990s World Trade
    Organization agreement. The implications of this
    are not at all clear, however.

24
Prediction/Guess 3
Do not be surprised if the GM issue dies down
considerably as scientists find non-transgene
approaches (e.g., marker assisted selection) to
incorporating molecular-biological knowledge into
crop improvement and as scientists and
biotechnology firms alter their research
priorities. Sophisticated NGOs are not much
opposed to virus-resistant crops and to crops
developed through marker-assisted breeding.
25
Prediction/Guess 4
  • Most consumers (in the US) tend not to be
    persuaded at all that biotechnology is good or
    ought to be pursued because it increases
    productivity or reduces agricultural product or
    food prices.
  • Look for changes in biotechnology research goals,
    and in discourses about why biotechnology is
    valuable.

26
Where is the GM Issue Heading?
My Guess Three possible complementary
scenarios
  • Continued US/Europe-Japan stalemate
  • GM crops become obsolete because of insect and
    weed resistance, and there are no significant new
    single-gene traits in the pipeline.
  • Advances in the genomics and computational
    biology make possible intraspecific (as opposed
    to interspecific or transgenic) breeding of
    crops, so that there is no longer a rationale for
    researchers and corporations to butt up against
    public resistance to GM/transgenic crops.
