The Rockefeller Foundation (RF) is a US philanthropic institution that was instrumental in shaping the Green Revolution. In 1998, the Foundation adopted a new programme strategy especially to target poor and marginalized people throughout the world. The Monitor spoke to the president, Gordon Conway, and the director of the food security programme, Gary Toenniessen, on the implications of this new course for agricultural research and biotechnology.
Monitor:
Mr. Conway, your
recent book calls for a doubly Green Revolution. What does this idea entail?
Conway:
The idea of a
doubly Green Revolution came about because we know we need to enhance food
production over the next 30 years just as we did in previous decades to keep up
with population increase. We also know that we are running out of land on which
we can expand agriculture, so food production has to be expanded by increased
yields. Essentially we need another Green Revolution. But we also know that the
new Green Revolution has to be more environmentally sustainable. We have to
avoid the problems of pesticides and the overuse of fertilizers. And we have to
have a greater diversity of cropping systems. However, equally important is
that a second Green Revolution should reach the poor. The previous Green
Revolution did benefit the poor, in part, because prices for food were lowered,
but it did not bring universal improvement. That is why we have 800 million
people chronically undernourished now. The people by-passed, for instance, are
those living in urban areas, poor people in the Green Revolution lands, and
those groups who live on marginal lands. Therefore, the new Green Revolution is
going to aim at these groups as well.
Monitor:
Does this mean
that your programme will no longer target farmers who have already profited
from the first Green Revolution? Or just that it will no longer exclude
marginalized farmers?
Toenniessen:
There has been a
shift away from tackling both groups of farmers. For instance, a lot of our
rice biotechnology programme was concerned with further improvements for
farmers on the Green Revolution lands. With Mr. Conway’s arrival in 1998, we
have focused more on those farmers who have benefited very little so far from the
Green Revolution.
Conway:
Presently our
priority is to tackle the big problems that poor farmers face, such as drought,
salinity, or Striga weed in Africa.
Monitor:
In dealing with
these problems, what will be the role of biotechnology for the Foundation?
Conway:
We have to
distinguish between the different kinds of biotechnology, of which at least
three are important. The first one is tissue culture to cross species
that would only very rarely cross in nature. For instance, there are two
different species of Oryza, the African and the Asian rice. The African
rice grows vigorously in dry conditions and smothers weeds. By crossing two
species the rice starts out as African rice and then becomes like Asian rice
with high yields. The second is marker-aided selection. This technique
helps to identify a gene in normal crossbreeding. For example breeding against
rice blast, a rice disease common in Asia, would traditionally involve growing
the plant and then infecting it with blast to see whether it is resistant.
Using molecular markers the whole procedure is accelerated because this process
detects whether the resistance gene is present in a new cross without actually
going through the whole plant cycle. The third is genetic engineering,
which is used if it is not possible to transfer certain genes by traditional
means. This is the case with the beta-carotene enhanced or so-called Golden
Rice. Pro-vitamin A or beta-carotene occurs in the entire rice plant except in
the grain. However, it was not possible to enhance it in the rice grain using
traditional means.
Monitor:
Golden Rice has
attracted a lot of attention. Critics contend that lack of vitamin A and
micronutrient deficiency is a complex phenomenon, which is, to a large extent,
caused by the decline in the diversity of food. In this view, vitamin-enhanced
rice is just a technical fix.
Conway:
I always want to
reply to that by asking about HIV/AIDS. Are critics going to say we should not
be producing a vaccine, because we could solve the whole AIDS problem by changing
people’s sexual habits? Vaccines are not a magic bullet, and neither is Vitamin
A enhanced rice. The argument about the range of crops of course is true.
People in affluent societies do not suffer from vitamin A deficiency because
they have a range of foods. This is not the case for many people living in
urban settings in developing countries. For example, one of the problems is
that mothers often take their babies off breast milk very early and wean them
with rice gruel instead. And that is when the vitamin A deficiency starts to
kick in. Furthermore, a great many developing countries are in semi-arid areas
with little to grow in the dry season. People could have gardens around their
houses if they dug wells and maybe this is the answer. However, this approach
might take longer than providing rice that is storable in the dry season.
Monitor:
Who is more in
need of beta-carotene enhanced rice, poor people in developing countries or
agrobiotechnology companies?
Toenniessen:
Both need it,
but vitamin A-deficient rice consumers clearly need it most. The companies are
using it for public relations purposes even though they had nothing to do with
its development. style="mso-spacerun: yes"> The result is too much
publicity and controversy about a research product that is still in the
development phase. Yet it would be a tragedy if the controversy thwarted the
further development and distribution of Golden Rice by public sector
institutions.
Monitor:
At any rate,
this new rice will not be at hand tomorrow.
Conway:
True. In the
meantime we are also supporting Vitamin A supplementation in schools, for
example in Ghana. But the problem with that approach is that one has to make
sure everybody goes to school. And of course we know that in poor areas
children do not always go to school.
Monitor:
These issues
touch on the complexity of food systems and livelihood, as they combine
agro-ecosystems, social, economic, and ecological considerations. Are you
concerned that the hierarchy of ‘hard’ and ‘soft’ sciences is likely to be
reinforced with the growing importance of genetic engineering?
Conway:
I have nothing
against hard science. As a matter of fact it can help soft science. What I am
concerned about is hard science driving the agenda. For the Foundation’s
application of genetic engineering and other biotechnologies, it is not the
hard science that is driving the agenda, but the problems. After identification
of the problems one has to look for the solutions; sometimes the solution to
the problem may be genetic engineering, sometimes not.
Monitor:
How can farmers
take part in shaping technology, especially in the case of genetic engineering?
Farmers might participate in selecting varieties, but in the end they will
always depend on receiving technologies they cannot develop themselves.
Toenniessen:
Farmers know
very well which characteristics they prefer, so they do participate in the
evaluation and the selection, and may even participate in making crosses. As
far as genetic engineering is concerned, we need a feedback system that gathers
information from the farmers and from the field researchers. For example, the
farmers identified the need for a Striga-resistant maize. Such
information goes back to an International Agricultural Research Centre
(IARC) or it comes back to us and then we can identify an appropriate advanced
laboratory. It may also be a company that is willing to make a commitment to
try to use the most advanced science to generate the product that the farmers
have indicated they need.
Monitor:
Was that also
the procedure that led to the development of beta-carotene enhanced rice?
Toenniessen:
No, it did not
start within a programme that was designed to solve Vitamin A deficiency.
Beta-carotene enhanced rice goes back to the beginning of the Foundation’s rice
biotechnology programme, when the objectives were different. Back then, the
Foundation was concerned that new biotechnologies that could contribute to crop
genetic improvement were not being applied to any of the crops or any of the
traits that were important in developing countries. In both the private sector
and the public sector in industrialized countries, these technologies were
being employed for crops important in their own countries that were financially
more attractive. Therefore, we started a programme to build capacity in Asia to
use these new biotechnologies and, while we were doing so, we asked what were
the most important traits that we could introduce into rice? One of the traits
that were identified, by talking to breeders, sociologists and economists, was
beta-carotene enhanced, yellow endosperm. It became one of two dozen traits for
our programme, targeting particularly poor farmers and poor consumers.
Monitor:
Which of your
biotechnology projects do you expect to make the biggest difference within the
next five or ten years?
Toenniessen:
Probably drought
tolerance. We are making a major effort to use marker-assisted selection to
produce drought tolerant rice and maize. And if this is possible for rice and
maize, it will probably be feasible for all the cereals because of the
similarities that exist between the grasses. This could have the biggest impact
on those who were bypassed by the Green Revolution because they did not have
access to irrigation.
Monitor:
Would that be a
combination of all the three biotechnologies you mentioned earlier?
Toenniessen:
Marker-assisted
breeding will be of primary importance. We are talking about multiple traits,
each of which is governed by multiple genes. Transferring a single gene is not
going to contribute much to drought-tolerance. In general, we think that
marker-aided selection is going to have a lot more positive impact on the
traits and on the people we are interested in than genetic engineering.
Conway:
Another
important trait would be Striga weed resistance. According to the United
Nations’ Food and Agriculture Organization (FAO), by 2000 Striga had
caused damage worth US$ 7 billion. That is an extraordinary figure, especially
since it hits basically poor farmers. The answer is going to be an integrated
answer, which includes cultivation, use of legumes and some form of
biotechnology, which may or may not be genetic engineering.
Monitor:
Mr. Conway, you
were engaged in the public discussion regarding the so-called terminator
technologies that render seeds sterile. Companies such as Monsanto (USA)
and AstraZeneca (Sweden/UK) have officially declared that they will not
commercialize such technologies. On the other hand, we see that the United
States Department of Agriculture (USDA), as well as other corporations
continues with the development. What do you expect for the future?
Conway:
Our concern in
the Foundation has been to ensure that new varieties are freely available to
poor farmers. And in particular that poor farmers can keep varieties from year
to year, and swap them with other farmers, because that was how new varieties
were distributed during the Green Revolution. We are not interested in
discussing whether such genes are good or bad for industrialized countries.
However, I think the fact that Monsanto and AstraZeneca have forsworn them is a
major step. It would be very difficult for a major biotechnology company to put
seed sterility genes into a crop in a developing country now. The opposition
would be too great.
Monitor:
The ‘terminator’
genes are only the technical solution to the broader issue of Intellectual
Property Rights (IPR). Is this a necessity or an evil that you have to deal
with?
Conway:
We are in favour
of the old Plant Variety Protection System as opposed to patents. This means
that plant breeders could market their seed, but another plant breeder could
work with it and then market a new variety himself. But I think we have to be
realistic, it is very difficult to go back to that old system. What we are
interested in is a step forward towards public-private partnerships to make
advanced techniques available to our target group.
Monitor:
The development
of beta-carotene enhanced rice is accompanied by complicated IPR issues. Did
the Rockefeller Foundation, therefore, suggest that the inventors at the Swiss
Federal Institute of Technology should enter a partnership for
commercialization with AstraZeneca, a private company?
Toenniessen:
No, the
partnership was achieved without us, but we advised that it would be a good
arrangement as far as intellectual property was concerned and also to
facilitate the biosafety and nutritional testing. We are continuing to fund the
inventors. If we did not like the agreement we could have terminated the
funding.
Conway:
We think that
the cooperation can make this rice freely available to farmers in developing
countries. In the end we achieve what we want, and probably more quickly and
easily than through the public system.
Monitor:
Philanthropic
organizations are very specific actors. Like governments from industrialized
countries, they provide financial resources. On the other hand, they are not
democratically endowed. What will be the future role of the Rockefeller
Foundation?
Conway:
If you think of
modern society as a three-legged stool, with government, the private sector,
and the not-for-profit sector as the three equal legs of a modern society, we
have a facilitating role in bringing them together at all levels. We do it by
linking up United Nations bodies such as the World Health Organization
with pharmaceutical companies and we also do it at the village or town level.
However, because of our size and history it remains a peculiarly American
philanthropic role.
Monitor:
New
philanthropies, such as the Gates Foundation (USA), have more money to
spend. Will this lead to competition?
Conway:
No, rather
cooperation. They might have greater financial resources, but they do not
necessarily have the infrastructure. For instance, our organization is already
established in Africa, and when we created the International AIDS Vaccination
Initiative (IAVI), which is now an independent NGO, the Gates Foundation
also contributed.
Monitor:
What is the
rationale behind the IAVI?
Conway:
The basic
premise is that although some of the big pharmaceutical companies were
interested in vaccines, they neglected vaccines for the African or the Asian
market, where the HIV strains are different. We believed that with a certain
financial inducement we could get pharmaceutical companies, in particular small
biotech companies, to work on producing new vaccines. At present IAVI has four
vaccines in the works at very early stages, for which the first safety trials
are now being conducted in Kenya. This initiative is a good example of what is
now called venture philanthropy.
Monitor:
Do you think
this could become an example for the agricultural sector as well?
Conway:
It is possible,
although in a way we have already got that with the institutes of the Consultative
Group on International Agricultural Research (CGIAR).
Toenniessen:
Within the
agricultural area we do not yet have a mechanism for linking the private and
public sectors together in a common task, like developing a vaccine.
Furthermore, there is one important difference. In the health area we are
dependent upon the private sector to develop the final product. There is no
public sector capacity to do all the clinical trials and actually produce and
deliver a vaccine at the end. In agriculture we still have public sector
institutions that are able to breed and to produce a final variety and to
distribute the seeds to the farmers. We do not want to lose this capacity,
especially not in developing countries, because it is the best way to deliver
the product to poor farmers at minimal costs.
