Biotechnology in the Rockefeller Foundation’s new course of action
Interview with Gordon Conway and Gary Toenniessen
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.
