Agricultural biodiversity where you least expect it

Continuing our in-depth treatment of The Economist’s (unwitting?) coverage of agricultural biodiversity, two items in the most recent issue. First, consider this photo:

It’s from an article on the BBC World Service, and clearly shows the value of a radio in Africa. But what’s that the listener is holding? Could it be a cavy? I rather think it could, and of course one wouldn’t expect The Economist to mention its origins in the Andes. We, however, still want to know when they arrived, how they got there, and whether they are proving the “indispensable” option they were thought to be.

Then there’s this little table, from an article on price fixing and cartels.

See those innocuous little entries for F. Hoffman-La Roche, labelled Vitamins? Those reflect decisions more than a decade ago by the US and the EU to fine not just Hoffman but a bunch of other pharmaceutical companies for fixing the price of vitamin A supplements, proof enough of the economic value of treating vitamin A deficiency as a simple medical problem requiring a simple (and expensive) medical fix. And most of the time, synthetic supplements aren’t even that useful to the children who get them. How else might you improve vitamin A levels? Well, you could try promoting a more diverse diet. But where’s the profit in that?

p.s. I was slightly saddened to see that while Hoffman remains joint number 1 in the EU, it has slipped to a poor 5th in the US. So I ran the numbers through an inflation indexer, which brings the $500 million up to $705 million in today’s dollars, which at least bumps them up a place.

So how many crops feed the world anyway?

I am conscious of the fact that in my recent short post on the paper “Increasing homogeneity in global food supplies and the implications for food security” I did not actually provide the answer to the question that the lead author, Colin Khoury, asked four years back on this blog, when he began thinking about doing the study. And that is: How many plants feed the world?

Well, of course, almost 25 years ago Prescott-Allen and Prescott-Allen (1990) said that “85 species commodities and 28 general commodities contribute 90% of national per capita supplies of food plants.” Because of changes in the way agricultural statistics are recorded, it’s difficult to make exact comparisons, but here’s the money quote summarising the changes:

The total number of important crop species we identified remained relatively consistent in comparison with a previous point estimate based on national-level data from 1979 to 1981 (Prescott-Allen and Prescott-Allen, 1990), but the spread and abundance values of these crops have changed measurably. The rate of movement toward homogeneity in food supply compositions globally continues with no indication of slowing. This trend implies a likely deterioration in importance of unreported minor and geographically restricted food plants, along with the measured cereal, oil, starchy root, and other crops that displayed significant declines in abundance in national food supplies. Thus, even as the number of measured crops available to the consumer in a given country has increased over the past half-century as a global trend, the total diversity of crops contributing significantly worldwide has narrowed.

So, if you must know, it’s about 94 plant species that largely feed the world. To be more precise, according to the analysis of Colin and his colleagues, we can now say that 50 crops, or 94 species, contribute to 90% of food supplies at national level. If you want to know what they are, you’ll need Table S1 in the paper. Because FAOStat, which is the dataset which both Prescott-Allen and Prescott-Allen (1990) and this paper uses (and for which, therefore, despite all its faults, we should all be grateful) records only a particular set of (52) relatively big crops, it’s not easy to know what’s happening with consumption of other, more local crops. We do know from many local studies that a lot of them are declining in both cultivation and consumption. But also that something can be done about it. Look at quinoa. History is not destiny. So maybe 95 species feed you if you’re Bolivian or a hipster. And Henry Hargreaves and Caitlin Levin need to re-think their food maps.

Quinoa misconceptions unmasked

Sure, the International Year of Quinoa is done, and our last substantial post on that iconic Andean pseudocereal was six months back, but the controversy over the environmental and socioeconomic impacts of its increased cultivation rumbles on, albeit at an intensity markedly less feverish than formerly. The latest salvo is a piece by Charlotte Ambrozek and Martin Zorrilla of the Department of International Agriculture and Rural Development, Cornell University, in collaboration with Bioversity International. Apparently the full article and references are available on request from Bioversity International’s economist, Dr Adam Drucker. We take the liberty of reproducing the article here (and adding a few links) because the only online version we can be sure to find, once it disappears from the page presenting whatever happens to be the latest issue of the SAVE Newsletter, will be a rather clunky PDF. We hope nobody is offended by any of that. We just want the piece to be as easily accessed as possible by as many readers as possible.

Agricultural biodiversity is a strategic asset, particularly for rural people. Agricultural biodiversity has a role in increasing agricultural sustainability, maintaining resilience at the landscape level, facilitating the ability of communities to adapt to a changing climate, improving their diets and nutritional outcomes, and increasing their food security. Diverse traditional crop species can have higher nutritional values than some major crops, as well as having multiple uses for the household. Considering that in 2010-2012 there were 870 million people who went hungry, 840 million who were obese and 2 billion who suffered from at least one micronutrient deficiency, as many tools as possible to tackle this triple malnutrition challenge of hunger, obesity and nutrient deficiencies are needed.

Agrobiodiversity conservation represents a strategic opportunity to address the malnutrition challenge. Bioversity International’s Payments for Agrobiodiversity Conservation Services scheme on quinoa in the Andes is an example of one such mechanism to conserve agricultural biodiversity and improve food security outcomes.

The scheme focused on quinoa as a case study example as increasing demand for a few varieties of the Andean staple is leading to the displacement of many other varieties and the loss of crop diversity. Its high nutritional status as a “superfood” even led NASA to decree it ideal for missions in space. Quinoa is now so popular that the United Nations named 2013 the International Year of Quinoa. Yet some impacts of quinoa’s popularity have become controversial in the popular press. A recent maelstrom of press articles on the The Quinoa Controversy was ignited by a provocative piece in The Guardian entitled “Can Vegans Stomach the Unpalatable Truth About Quinoa”.

The articles essentially argue that increased production of quinoa in Bolivia and Peru, the ancestral homeland of this Andean grain, has had negative social and environmental impacts on small farmers. This conclusion is based on alleged Bolivian government reports that showed that domestic quinoa consumption has decreased in recent years. Most authors attributed this drop to the price of quinoa, which has tripled in the past six years. Similarly, increased production and mechanization has been linked to ecosystem degradation and social conflict, particularly related to land access.

The “quinoa quandary” story was soon being carried by a dozen or so major news sites, and countless independent bloggers. We examined 42 such stories written between 2011-2013 in order to understand how the Western world interpreted this complex issue involving malnutrition, commodity markets, land degradation, and globalization.

Not only has the decreased-domestic-quinoa-consumption claim by the New York Times in 2011, been contradicted by later data suggesting that domestic consumption over the past four years has in fact tripled, but further misconceptions exist. The most common is that high price of quinoa was responsible for malnutrition and poverty in the Andes. High prices of quinoa increased incomes for farmers, and actually inspired a generation of rural poor who had moved to the city to return to farming. Less sensationalist press stories revealed that while malnutrition was occurring among some families, it was more likely due to cultural reasons. Quinoa in the Andes has traditionally been a poor person’s food; as farmer incomes increased so did their tendency to replace quinoa with more western processed foods.

Another element missing from almost every press report was the opinion of Bolivian and Peruvian journalists and academics. Interestingly, our survey of Andean press sources found a very different take on the controversy. One thing became particularly clear: Bolivians and Peruvians are not begging Americans to stop eating quinoa. Many do not see high quinoa prices as a serious threat, given the economic benefits to farmers and the country as a whole. Rather Andean critics were often incredulous, with some expressing suspicion at the attention that the issue has received in the United States. One Bolivian news source suggested some US sources were calling for increased North American quinoa production merely in order to stimulate United States domestic quinoa production for their own market. Of the Bolivian news sources that have called attention to high rates of malnutrition among farmers, many point out that domestic quinoa consumption was historically low, prior to its rise in popularity in the West (in part as a result of practices during the colonial period).

However, the most striking difference between Andean and Western perspectives on the controversy lies in the proposed solutions. American journalists and bloggers almost universally emphasize consumer choice and how it should change, distilling the complex problem to a binary choice: eat quinoa or don’t eat quinoa. Andean sources instead recommend solutions to be achieved through policy changes and collective action. Articles often call for the government to prioritize domestic consumption, attempt to popularize quinoa consumption and subsidize its consumption in school lunch programs. To many Bolivians and Peruvians, increased quinoa demand is unquestionably a positive outcome, while negative side-effects are the result of poor agricultural policy and a lack of market regulation.

Whether in Bolivia or the United States, the increased price and production of quinoa has generated a strong reaction. The bubbling controversy reveals much in terms of how we view our food system and the global economy. It tells us that we, as Westerners, understand remarkably little about how our choices as consumers actually affect producers in other countries. It plays into a Global North vs. Global South view on those choices, and how people see avenues for change. Yet ultimately it tells us that people care, they care about the food they eat, and they care about the people who don’t get enough food to eat. The real question is how to turn that concern into increased food security for developing country farmers based on sustainable agricultural practices.

More on TePuke rice in New Zealand

Attentive readers may remember a post from some years back about the return of TePuke rice from IRRI’s genebank to New Zealand. Via our friends at IRRI, here’s photographic proof from Tony Olsen, a local farmer, that he actually planted that variety at what would be a world record southern latitude for the crop (even further S than Rocha, in Uruguay)…

5 Planting Rice 012[7]

…and that it actually grew, despite a not very sunny summer.

7 Maturing[22]

We wait to see whether there’s a decent harvest.

Incidentally, although IRRI was able to send Tony some seeds of TePuke, he says that:

A friend of mine helped me track down some TePuke Gold Rice seeds from the widow of the gentleman who supplied them to the NZ authorities that forwarded them to your institute in the 1970’s.

Which just goes to confirm that people really like holding on to their seeds.

Anyway, what with dire predictions about what will happen to rice yields in its Asian heartland, it might well be that places like New Zealand and Uruguay, now on the edge of the crop’s range, are going to feature much more prominently in the future. Maybe even parts of Japan, which has a young breed of farmers coming through who I’m sure are just itching to take on such upstarts.
