Bio: Norman Uphoff is a professor of Government and International Agriculture at Cornell University and former director of the Cornell International Institute for Food, Agriculture, and Development, 1990 to 2005. His work has focused on development administration, irrigation management, local participation, and strategies for broad-based rural development. His current development interests have expanded beyond the social sciences to include agro-ecology, particularly the System of Rice Intensification (SRI) and its extrapolation to other crops beyond rice.

On Nourishing the Planet: Nourishing the Planet is looking ahead at ways that we can, first, avert the most dire outcomes that will be the likely consequence of our present practices, and, second, reverse the present adverse trends by capitalizing on new opportunities. Both are necessary. Not enough people realize that we are ‘in a hole,’ and that continuing to ‘dig deeper’ will not get us out.
Our food production methods need to be reformulated and reoriented to approximate more closely the natural processes that have supported vegetation growth on the planet’s surface for some 400 million years. All herbivores, carnivores and omnivores (including us) are supported by these photosynthetically-driven processes and their associated soil system dynamics. Nourishing the planet in the decades ahead will depend on a profound understanding of ecological opportunities and limits.
The December 2009 issue of Farming Matters calls you “one of the most energetic and persistent promoters of SRI.” Can you describe your evolution from being a skeptic of the technique to becoming one its biggest supporters? When I first learned about ‘SRI’ from the Malagasy NGO Association Teffy Saina in December 1993 it sounded fantastical. How could farmers, who had very poor soils, significantly improve their yields—by 5, 10, even 15 tons per hectare—without the use of new, improved rice varieties, and without the use of chemical fertilizer (just compost made from any available biomass), and with less water? This was not believable. Even though I was a social scientist, not an agronomist, I knew this was not possible.
But the Teffy Saina officers who offered to work with us were quite confident, and the Malagasy professional managing the project vouched for their character, so we signed the subcontracts with Tefy Saina to introduce SRI in the peripheral zone of the USAID-funded conservation and development projects intended to save the rainforest ecosystems around Ranomafana. After the farmers used SRI methods for three years, they averaged eight tons per hectare, and some reached 12, 14, and 16 tons per hectare in one case. I decided that I had better learn enough agronomics to figure out what was going on, and enough French so that I could understand the papers for the originator of SRI, Fr. Henri De Laulanié, S.J. He has spent 34 years of his life trying to help poor farmers in Madagascar raise their rice yields without depending on purchased inputs. To my everlasting regret, I never met him before he died in 1995, and because I was still to skeptical about SRI to realize what a remarkable innovator he was, in the tradition of Gregor Mendel.
The same story in Farming Matters emphasizes the importance of involving farmers’ needs and opinions when developing innovations. How does your research and outreach integrate the feedback of farmers using SRI on the ground? In part because most agricultural scientists have been so skeptical, even dismissive of SRI, our work has usually begun with NGO’s and the farmers they assist. There have been a few agricultural researchers who have had open minds and have taken an interest in SRI from the outset, but mostly we have developed our understanding of SR and have made adaptations in close association with farmers. Now the scientific community is becoming more interested.
Because SRI is ‘not a technology,’ nothing fixed or rigid, but rather a distillation of the insights and methods that Fr. Laulanié put together from his own experience and from working with Malagasy farmers, we try to explain to farmers the reasons for changing their age-old management methods for plants, soil, water, and nutrients, rather than telling them how they should change. We want farmers to understand the rational, and to make adaptation to their own local conditions: how young seedlings should be for their soils and temperatures, how far apart is the optimum spacing, how much they should let their paddy soils dry out before re-wetting them, etc. Some farmers have quickly grasped the principles and techniques, and become leaders in their own communities, and beyond. We start with those who are most curious and innovative and try to spread them from there.
What are the qualifications you look for in a successful innovation and how do suggest information about the innovation can most effectively be shared? That not all farmers adopt something immediately does not mean the innovation has no merit, or will not spread once its productivity is demonstrated and once appropriate adaptations have been made for local conditions. SRI was developed for irrigated rice production, for example, with transplanting as the method of crop establishment. But we have seen the ideas successfully extrapolated to rain-fed (non-irrigated) rice production, using only rainfall, and also extended to other crops. When farmers take ownership of an innovation this way, maybe only a few at first, this is a mark of success. Farmers in many countries have taken it upon themselves to spread the innovation to other farmers. That was very persuasive to me.
What kinds of policy changes would you like to see implemented immediately to address the needs of small scale farmers? This is too broad a question for a quick answer. To support SRI extension, perhaps the first thing would be to improve the physical infrastructure and (especially) the management of irrigation systems so that more water can be provided reliably to farmers wanting to get more yield with less water. Also, because SRI paddy (unmilled) rice gives about 15 percent more milled rice per bag or per bushel, because there is less chaff (fewer unfilled grains) and less breakage of grains during milling, millers should pay 10 percent more per bag or per bushel for SRI paddy, to give the benefit of the higher quality rice to its producers (rather than pocket this windfall themselves). That would be a big boost to getting farmers to shift their production methods since this is on top of a higher paddy yield.
Can you discuss the relationship between consumers in the United States and small scale farmers in Africa? I think that fair trade should be promoted more widely, and subsidies to U.S. farmers that tilt the playing field against African small-scale farmers should be revised and probably ended. If the U.S. wants to promote free trade, it should itself be practicing fair trade, i.e. unsubsidized production.
Why should food consumers in the United States care about the state of agriculture in other countries? In the case of SRI, reduced requirements for water (more crop per drop) do not directly affect U.S. consumers, but the whole world benefits from movement toward more water—economizing food production. In the case of SRI, the reduced requirements for water (more crop per drop) do not directly affect U.S. consumers, but the whole world benefits from movement toward more water-economizing food production. Also from less use of synthetic fertilizers and agrochemicals. We have been working with a U.S. rice-importing company in San Francisco, Lotus Foods, to help them import very high-quality indigenous rice varieties, organically-grown by small farmers with higher income for their produce, which helps conserve rice biodiversity and benefit farmers and the environment.
Few U.S. consumers realize the richness of rice biodiversity (oryza sativa), with thousands of varieties having desirable qualities of taste, texture, color, aroma, etc. and often higher nutritional quality. I think that with the increase productivity of SRI methods, also for traditional varieties as well as improved varieties, lowering the prices of rice for consumers while still giving farmers a better income, we are going to see rice becoming a much more popular and widely-consumed food in the 21st century. Rice is much more and much better than the ‘white stuff’ that used to be consumed just for its calories. Rices are good for soups, salads, desserts, casseroles, poultry stuffing, etc. Few Americans know what a wonderful grain the many kinds of rice can be; but now that SRI methods are being used for wheat, millet, sorghum, teff, and other grains, I have to avoid becoming a complete partisan for rice.
