Food politics: Marion Nestle's "Why Calories Count"

I haven't actually read Marion Nestle's Why Calories Count yet, but I am getting the gist of it through her great blog, Food Politics. Now I'm sure you already know about my fascination with the history of calories and food politics, as I previously wrote about. So I can't wait to get her book!

In a recent post, Nestle writes,

If you want to understand calories, you need to know the difference between calories measured and estimated. Most studies of diet, health, and calorie balance depend on self reports of dietary intake and physical activity or educated guesses about the number of calories involved. Most diet studies rely on estimates. When it comes to anything about calories in food or in the body, you have to get used to working with imprecise numbers. That is why it works better to eat smaller portions than to try to count calories in food. Even small differences in the weight of food will throw calorie estimations off. [emphasis added]

This struck a chord with a recent class discussion. We were discussing democratizing science, and our instructor referenced a concept developed by Donald Mackenzie in his book, Inventing Accuracy, which is the "certainty trough." People extremely close to an issue, likely scientists, perceive the exact uncertainties of the issue. A great analog here is climate scientists, who are very careful to not underestimate the uncertainty associated with climate change. But others involved in the climate regime, such as practitioners and activists, perceive a lower uncertainty- they are in the "certainty trough." To outsiders, uncertainty is perceived as even higher- for example, climate might be seen as an "act of God" or a random event like weather. Also, there are actors manufacturing and exploiting uncertainty, as Naomi Oreskes and Erik Conway show in their book, Merchants of Doubt.

So as Nestle says, for food practitioners, i.e. anyone who eats, "you have to get used to working with imprecise numbers." No matter how much nutritional scientists narrow down the science of metabolism, it is still highly dependent on biological factors unique to our own bodies. Food and diet are a series of constant experiments where we must embrace uncertainty.

This concept of embracing uncertainty applies to more than just food consumption, but also to other parts of the food system. I've been working on publishing a factsheet on greenhouse gas emissions from food systems, and the truth is, there is a high degree of uncertainty within the system, making it very difficult to get an exact measurement of the "food miles" or "carbon footprint" of any one food. But this shouldn't paralyze us from making common sense changes, be it in our diet (eat less meat, buy less packaged/processed food, buy only what you will eat) or in our agricultural and commercial processes. As Nestle suggests, "get organized; get motivated... eat less, move more, eat better and get political."

Seed banking, 1979–1994

Seed banks, such as the so-called "Doomsday Seed Vault" have been in the news recently, and I think will play a big role in crop adaptation to climate change. As part of the Embryo Project at ASU, I've been researching the history of seed banks. I posted about Seed Collection, 1990–1979 last week.

In the early twentieth century, scientists and agriculturalists collected plants in greenhouses, botanical gardens, and fields. When scientists became concerned over the loss of plant genetic diversity due to the expansion of a few agricultural crops around the mid-century, countries and organizations created seed banks for long-term seed storage. Beginning around 1979, environmental groups objected to the limited access to seed banks and questioned the propriety of the intellectual property of living organisms. Because many of the seed banks were located in the global North yet plants were collected largely from countries in the global South, this caused prolonged controversy over the uneven flow of genetic resources. This movement of the so-called “seed wars” and the movement for biodiversity conservation intersected in ways that shaped debates over plant genetic material and seed banking. Several significant shifts in governance occurred in 1994, leading to the creation of the International Plant Genetic Resources Institute and a change in the governance of several important international seed banks. 

The International Board for Plant Genetic Resources (IBPGR), headquartered in Rome, Italy, oversaw many, but not all, seed banks around the world. Through the efforts of the IBPGR and different countries, plant germplasm collection exploded in the 1970s and 1980s around the world. Plant germplasm is the genetic material required for plants to reproduce, mainly seeds, but also including clones, or cuttings. As of 1993, the IBPGR had conducted more than 400 collecting missions in over 100 countries. Seed banks also proliferated during thus time. As of 1979, twenty-five seed banks for long-term storage existed in the world. By 1995, 129 countries held a total of 1061 germplasm collections.

A 1979 book by Pat Roy Mooney, Seeds of the Earth: Private or Public Resource?, set off a movement of protest against seed banking. Beginning at a 1979 Food and Agriculture Organization (FAO) conference, representatives from developing countries expressed discontent with the seed banking regime, citing Mooney’s arguments that genes discovered in the global South would be patented in the North, and consequently, that the plant genetic material would no longer be available to farmers in the South. Mooney and others have made the distinction between “gene rich” countries in the global South and “gene poor” countries in the global South, which nonetheless possess more resources for seed collection and storage. Erna Bennet, a scientist and FAO employee, sympathized with these concerns and advocated of farmers’ access to germplasm from her earlier work with the FAO. As a proposed solution, Bennet spearheaded a campaign for the FAO, rather than the IBPGR, to gain jurisdiction of the global seed banks. Bennet resigned from the FAO in 1983 because of unresolved conflicts.

By 1981 the issue of seed banking, and the connection between intellectual property rights and conservation, became a global issue. Developing countries feared that germplasm collected in their countries would be stored in developed countries, such as the US, and that they would be denied access to the genetic material, prompting the phrase germplasm embargo. These countries called for the principle of free exchange of plant germplasm. In 1983 the FAO held a meeting that established the International Undertaking on Plant Genetic Resources, a voluntary, non-binding agreement, as well as an FAO Commission on Plant Genetic Resources. The International Undertaking would establish standards for the international collection and storage of plant genetic resources. The FAO believed that jurisdiction of international seed banks should be in the hands of a publicly accountable intergovernmental organization. The FAO was accountable to the United Nations, but the IBPGR and their institutional host, the Consultative Group for International Agricultural Research (CGIAR) were accountable to their donors, including the World Bank. Thus the FAO attempted to establish a Global System on Plant Genetic Resources for food and agriculture that would ostensibly replace the IBPGR. The Global System would include not just seed banks, but also on-farm conservation efforts.

The collaboration between the CGIAR and FAO revealed tensions between the organizations’ missions. Tensions between the FAO and IBPGR, both still located in Rome, Italy, continued into the early 1990s. In 1991, the IBPGR became the International Plant Genetic Resources Institute (IPGRI), officially ratified by the Italian government in 1994, and part of the CGIAR network. Jurisdiction over the global system of seed banks was still unclear until the United Nations Convention for Biological Diversity in 1992 in Rio de Janeiro, Brazil. In 1994, jurisdiction of the CGIAR’s twelve gene banks was transferred to the FAO.

The decisions of the UN Convention on Biological Diversity (CBD) in 1992 had consequences for plant genetic resource conservation. The CBD framework allowed legal rights over natural resources to their countries of origin. The CBD did not extend to existing seed banks, which were at the time under the auspices of the CGIAR network, but it set a precedent for international governance of genetic material, and left a gap for governance of seed banks. The Trade-Related Aspects of Intellectual Property Rights (TRIPs) in 1994 further established international standards for trade of plant genetic materials. Over the next decade, the FAO developed an International Treaty for Plant Genetic Resources for Food and Agriculture, widely adopted in 2002.

Seed banking allows long-term storage of plant germplasm, usually used for plant breeding experiments. To preserve germplasm, seed banks are kept at low temperatures and low moisture, which keeps the seed dry and stops samples from growing quickly. For long-term storage, seeds are stored in airtight vials at temperatures around -20 degrees C, and around 0 to -5 degrees C for medium-term storage. Thousands of seeds are stored for each plant variety. Samples can degrade over time, and especially in developing countries, the facilities may not be equipped for long-term storage. Most plants are stored as seed, but asexual or polyploidy crops such as potato, cassava and banana require different techniques for reproduction and storage. In the 1980s, seed banks experimented with techniques for storing these plants as tissue cultures, or “artificial seeds.” These varieties can also be propagated in test tubes for shorter-term storage. Cryopreservation, freezing seed in liquid nitrogen at extremely low temperatures, is another technique for long-term storage of plant material, but is not as widely used as it is in animal breeding and conservation.

Scientists often use the terms seed bank, gene bank, and germplasm collection interchangeably, although there are different techniques associated with storage of different plants and types of storage. Germplasm is all plant genetic material, which is limited to more than just seeds. Scholars Pistorius and Wijk assert that, in the 1980s, scientists began conceptualizing plant genetic diversity in term of individual genes rather than particular plants. The dominance of the term “gene bank” in scientific literature reflects this shift.

Seed collection and plant genetic diversity, 1900–1979

Seed banks, such as the so-called "Doomsday Seed Vault" have been in the news recently, and I think will play a big role in crop adaptation to climate change. As part of the Embryo Project at ASU, I've been researching the history of seed banks this is Part I: from 1990–1979. See my new post for Part II: Seed Banks, 1979–1994.

Although scientists lacked formal theories about genetics until the early 1900s, agriculturalists have long relied on genetic diversity to breed new crops. In the early 1900s, scientists began to recognize the importance of plant genetic diversity for agriculture. Scientists realized that crops could be systematically bred with their wild relatives to incorporate specific genetic traits or produce hybrids. In 1967, plant scientists led an international movement for conservation of plant genetic resources through the Food and Agricultural Organization, and later the Consultative Group for International Agricultural Research. Necessary to the conservation of plant genetic resources are the collection and storage of plant germplasm—the genetic material required to propagate a plant—usually in the form of a seed.

Throughout history, farmers, scientists, explorers, botanists, and agriculturalists collected exotic plants and tested the seeds in new environments, hoping to find new agriculturally important crops. Agricultural experimenters and collectors such as Thomas Jefferson stored germplasm in fields, greenhouses, and botanical gardens. The US government became involved in 1819 the US Patent Office and Navy began the official collection of germplasm from foreign consuls. This continued until the Civil War and the formation of the US Department of Agriculture (USDA) in 1862. The USDA distributed foreign seeds to farmers and agricultural experiment stations for testing, and created the Section of Foreign Seed and Plant Introduction, located in Beltsville, Maryland, in 1898.

The rise of genetic theories and the professionalization of plant breeding in the early 20th century contributed to early understandings of plant genetic diversity. Scientists such as Liberty Hyde Bailey, Rowland Harry Biffen, Hugo de Vries, and William Bateson popularized Darwinian and Mendelian concepts of natural selection and genetic laws, and their application to plant breeding. Based on de Vries’ mutation theory, scientists realized the importance of genetic variation to plant breeding. Bailey in particular strove to break the conceptual divide between crops in the field and plants in the wild, a theme that would influence plant breeding and seed storage throughout the century.

Governments in the US, Europe, the Soviet Union, Australia, and New Zealand supported early efforts at plant germplasm collection. In the early 1900s, the US commissioned famous plant explorer Frank N. Meyer, who the Meyer lemon is named after, to collect plant germplasm from exotic locations in Asia, Russia, and Europe. A Soviet botanist and plant explorer, Nikolai Ivanovich Vavilov (1887–1943), is considered a founder of theories of plant diversity, origin, and evolution. Vavilov studied plant genetics under Biffen and later Bateson in England. In the 1920s and 1930s, Vavilov raised awareness of the loss of plant genetic diversity due to the dominance of a small number of genetically similar crops, an argument that would form the basis of the movement for the conservation of plant genetic resources.

Vavilov proposed the influential theory of Centers of Origin, which were nine areas of the world where food crops originated from, such as the potato’s origin in Latin America. These areas were thought to contain the most diverse wild relatives of the crops due to evolution and genetic variation. Despite repression of Vavilov’s Darwinian ideas under Soviet Lysenckoism and Stalin, his theories spread throughout the world. Vavilov’s work inspired the botanists, plant breeders, and explorers who led the movement for conservation of plant genetic resources, including Erna Bennett (1925–2012), Otto H. Frankel (1900–1998), Jack R. Harlan (1917–1998), and John G. Hawkes (1915–2007) . The discovery of Centers of Origin increased the importance of crop wild relatives for plant germplasm collection and plant breeding. His Centers of Origin theory is now thought of as centers of diversity, because there is not always a clear genetic origin of plant varieties.

Beginning a movement for international development of seed collections, the Rockefeller Foundation [contributedTo] funded an effort to collect plant germplasm in Mexico in the 1940s. The Rockefeller Foundation launched the Mexican Agricultural Project (MAP) in 1943, which many consider the start of the Green Revolution. The MAP signaled the beginning of an era of systematic collection, evaluation, and storage of plant germplasm, in this case, maize, wheat, and potato germplasm. The MAP preceded formation of the first long-term seed storage facility, the National Seed Storage Laboratory in Fort Collins, Colorado in 1958. Prior to existing germplasm collections only provided short-term storage. After World War II, many countries, including India, Brazil, and Japan, had established “seed banks” for long-term storage of plant germplasm.

The Food and Agricultural Organization (FAO), an international organization located in Rome, Italy, became concerned about the loss of plant genetic diversity in the 1960s. During the late 1960s and early 1970s, concerns over the loss of plant genetic resources, which include everything from wild to domesticated relatives of food crops, became a high priority for the FAO. The FAO acted as a “clearing house” for plant exploration since 1948 by cataloging plant varieties and participating plant breeders and countries. The FAO also oversaw plant germplasm collections in countries around the world. In 1967 the FAO created a department of Crop Ecology and Genetic Resources, led by Bennett and R. J. Pichel.

In 1967 the Food and Agricultural Organization and International Biological Programme, of England, organized the 1967 Technical Conference on the Exploration, Utilization and Conservation of Plant Genetic Resources in Rome, Italy. This was a turning point in the movement for conservation of plant diversity. The conference popularized the term “genetic resources” and established a set of standards and plans for storage of plant genetic material outside of natural habitats and in seed banks. Two key scientists involved in the conferences, Bennett and Frankel, differed over this decision. Bennett advocated for farmer’s participation through conservation in the field, while Frankel advocated the seed banking approach. Frankel and the FAO favored the seed banking approach to conservation because it allowed plant breeders to selectively draw from stored genetic material.

Participants at the 1967 FAO conference also coined the term “genetic erosion,” meaning the loss of plant genetic diversity due to agricultural expansion. Genetic erosion became a pressing international concern after a major corn blight in 1970 in the US and the spread of coffee rust in Brazil. Echoing Vavilov, scientists highlighted the downfalls of a genetically homogenous crop population. In 1972 the US National Research Council authored an influential report, Genetic Vulnerability of Major Crops, stating a similar case.

The FAO advocated long-term conservation as a solution to genetic erosion. Yet the FAO was not a research organization, and lacked flexible funding and the ability to enact conservation methods. The FAO could not overlook the rise of international agricultural research centers in the 1960s, such as the International Rice Research Institute in Los Banos, the Philippines. These international agricultural research centers formally joined in 1971 as the Consultative Group for International Agricultural Research (CGIAR), under direction of the World Bank. The CGIAR proved fertile ground for the FAO’s goal of long-term germplasm conservation.

The FAO’s Panel of Experts approached the CGIAR in 1971 with the idea of integrating conservation of plant genetic resources into their existing agenda of international agricultural research. A meeting in 1972 between the CGIAR and FAO in Beltsville, Maryland, began talks about a global system for plant genetic conservation. The CGIAR relied on plant genetic resources for plant breeding, and already had some collections of germplasm. In 1974 the CGIAR and FAO formed the International Board for Plant Genetic Resources (IBPGR).

Under the direction of the FAO’s Pichel, the IBPGR, based in Rome, Italy, coordinated the collection, experimentation, and information dissemination of plant genetic conservation projects around the world. The IBPGR partnered with the CGIAR’s other international centers and national agricultural research centers to fund and create seed banks. These seed banks had multiple goals: long-term conservation, medium-term experimentation and propagation of germplasm for agricultural research, and short-term field experiments leading to new crop varieties.

In 1975, only eight seed banks existed in the world. This number would drastically increase under direction of the CGIAR and FAO, but not without controversy both within and outside of the IBPGR. The IBPRG changed leadership in 1979, when Trevor Williams replaced R. J. Pichel as executive secretary of the IBPGR. Publication of Pat Roy Mooney’s Seeds of the Earth: Private or Public Resource? sparked public controversy over access to seed banks.

Innovation in America: Debate between Kakaes and Sarewitz

As I mentioned earlier this week, Slate is hosting a conversation between Konstantin Kakaes and Dan Sarewitz on science and innovation. While I should be doing about 10 other things for school right now, I couldn't pass up the opportunity to commentate.

Kakaes, who is a journalist and a fellow at the New America Foundation, begins by questioning the pace of current innovation; claims that innovation is happening faster than ever and that the need for innovation is greater than ever. Second, he deconstructs the idea of measuring innovation, through patents and publications, as both of these metrics can't actually tell us the usefulness of their affiliated innovations. Finally, he ties this into an argument that because we can't measure innovation, we can't guide scientists to work towards positive societal outcomes. Kakaes refers to some of Sarewitz's previous popular publications, calling him out on perceived inconsistencies on his call for innovation for social goods.

Sarewitz, a professor of science and society at Arizona State University and co-director of the Consortium for Science, Policy, and Outcomes [full disclosure: he is also on my PhD committee], responds to Kakaes by summarizing his argument and pointing out that Kakaes is following the "serendipitous discovery" rhetoric. A closer examination of the history of technology shows that this narrative only plays well in political advocacy, as the strength of industry innovation during the 19th and 20th centuries show. Sarewitz argues that while allowing scientists a space for intellectual curiosity is important, the institutional structure of innovation can help shape the outcomes. Just giving money to brilliant scientists isn't enough. His favorite comparison is the Department of Defense, which invests in high-risk high-payout projects but also procures from multiple contractors and is ultimately the end-user of the technologies, and the NIH (or Department of Energy), which  invests in incremental basic research in biomedicine and has largely disappointed the advocates of diseases such as cancer.

Kakaes next responds stating that, "Talking about the 'pace of technological change' is only the tip of the spear of MBA-speak that is stabbing the academy." He argues that the attempt to quantify technological outcomes buries deeper truths about their social context. He argues that the constant need to justify science to politicians actually causes the rat-race of incremental advances. Kakaes dwells on the gap between scientific research and social prescriptions for this research, from biomedicine to cigarettes to climate change, citing that Francis Collins' "Translational Medicine" concept for the NIH also falls short of reconciling this gap. He ultimately argues that politics, rather than science is the "limiting factor" in delivering public goods.

Sarewitz carefully takes down every point Kakaes brought up, both turning the examples of the DoD, earthquake research, the NIH, and mouse models against each other. He again argues that the institutional context of research matters; that scientists aren't pursuing mouse models because of political pressure, but because that is the way field of biomedicine has institutionalized.

I'm looking forward to subsequent posts, and it's difficult for me to take an unbiased view on this, but I mostly agree with Sarewitz. Kakaes is championing a "Republic of Science" vision of unfettered scientific research; i.e. the golden age of physics. In response, Sarewitz writes, "the lessons of real-world, everyday science are quite clear: scientific creativity and real-world problem-solving are both at their best when they can feed off of each other." This is a statement I thoroughly support.

Food and climate; innovation; science; and authority

As always, sorry about the long blog break! I just spent the weekend in Washington, DC for the STGlobal annual conference for grad students. I helped plan the event and it went great! We had four presenters from ASU and three folks on the planning committee, so I was happy to see us well-represented amongst the East Coast schools.

I have sadly few deeper thoughts to contribute, and likely will be pretty busy as the semester comes to an end this month. For now, here are my favorite recent science policy links.

Last week some of my colleagues attended the Planet Under Pressure conference in London. Some of the discussion on agriculture is synthesized here:

• A Clarion Call on the Food Supply (quick read; h/t Arijit)
• Achieving Food Security in the Face of Climate Change (long read)
Who has Authority in Political Debates Involving Science?: Roger Pielke Jr. on the science and politics of Planet Under Pressure

On climate security and the role of the military, What to Do? The Climate Security Policy Conundrum at the Duck of Minerva.

WTF is pink slime and why does it matter? Marion Nestle, as always, sorts through the politics of food. Nestle argues, "even if technological processes like this are safe, they are not necessarily acceptable—especially if they are not labeled and do not give consumers a choice."

What Beer Can Teach Us About Emerging Technologies by an ASU/CSPO professor, Dave Conz.
In cancer science, many "discoveries" don't hold up. Yet another reason the NIH has some 'splainin' to do.

Is Science Really Moving Faster Than Ever? and a retort by Sarewitz tomorrow at Slate.

Finally, because I love food politics and MBF loves science fiction, The Hunger Games and the Politics of Food.
