Alcademics has a couple of cool Peruvian booze stories. And Time has a photo essay on yerba mate. Amazing the diversity of drinks you can make from agrobiodiversity.
Adapting in the Pacific
The New Agriculturist is out, and, among many other things, it features an interview with my old boss at the Secretariat of the Pacific Community (SPC), Aleki Sisifa. Aleki has some very sensible things to say about adapting to climate change. Here’s an example, but read the whole thing.
We need to help farmers stay ahead of climate change, and genetic resources are going to be crucial for that. At SPC we hold the genetic resources for the Pacific region, and as part of our climate change work we are collecting varieties that can withstand conditions such as drought, salinity and water-logging.
We are working to ensure fair use and ready access of these resources and, in June 2009, our collection was placed in the Multilateral System of the International Treaty on Plant Genetic Resources for Food and Agriculture. Around the same time, agreement was made with the Global Crop Diversity Trust to safeguard our collection of taro and yam, two of our most important food crops in this region.
GURT big mess
When are the knee-jerk opponents of genetically modified crops going to realize that genetic use restriction technologies (GURTs) are their friends? 1
The latest gusher of drivel comes from the International Institute for Environment and Development, which really ought to know better. In a press release designed to ride the intense interest swirling aound the World Seed Conference, which opened at FAO yesterday, IIED “researchers” point out that:
in order to continue conserving and adapting their varieties, farmers also need to be allowed to freely save, use, exchange and sell farm-saved seeds. Technologies which restrict these customary rights — namely Genetic Use Restriction Technologies (GURTS) — pose a very serious threat to genetic diversity, seed quality and the livelihoods of poor farmers.
New readers (and IIED researchers) should start here. GURTs (there are a couple of different kinds) are bits of DNA that are intended to prevent any seed that contains them from germinating and growing.
Why?
So that farmers cannot save their own seeds.
Which farmers?
Farmers who choose to buy the seeds that contained the GURTs because they think that those seeds offer them valuable advantages over other seeds.
Why?
Because a company invested a sackload of money in developing a variety. So the company is going to do two things to recoup its investment, and more. It must persuade farmers to buy the seed. And it must stop everyone else from making use of the investment without paying for it.
So far, note, this is nothing to do with GURTs, which in any case are not currently permitted in seed anywhere. It is one good reason why seed companies like to produce F1 hybrids. The seeds of an F1 hybrid are no good to the farmer who wants the same performance from the seeds she saved as from the seeds she paid for. In that sense, GURTs are a logical extension of the desire of seed breeding companies to protect their investment. You can save the seeds of an F1, but those F2 seeds are not a replica of the F1. The company wins, although canny breeders can easily dehybridize the hybrids, and even farmers can benefit from the flow of interesting genes into their crops.
Now, whereas F1 hybrids produce pollen that can indeed pollute the seeds of a neighbouring farmer exercising her right to freely save, use, exchange and sell farm-saved seed, GURTs actually prevent this kind of pollution. Any seed fertilized by pollen from a GURTed plant is effectively dead.
GURTs thus stop any characters bred into a GMO from being transferred into another variety of the same crop and into the crop’s wild relatives.
So, IIED, remind me, please: why is that a bad thing?
Does it stop the farmer saving seeds? On the contrary, it makes life easier, because the farmer does not have to worry about genetic pollution. She can, of course, still take advantage of good pollution, or introgression, if she wants to.
Does it stop her using farm-saved seed? No, how could it, when any polluted seeds are going to fail to grow. It makes using the farm-saved seed more secure.
Can she still exchange and sell farm-saved seed? You bet, and not only that, but her customers and swap-partners will be grateful that her seeds cannot possibly be polluted.
Opponents of GURTs seem to think that massive influxes of foreign pollen are the norm. They’re not. And I certainly wouldn’t want to accept, even as a gift, seed from someone who knew so little about farming and seed saving that they couldn’t even maintain their own varieties. Cross pollination from a different field is a fascinating and rare source of diversity in farmers’ fields, not the norm. GURTs pose absolutely no threat to farm-saved seed. In fact, I believe that they can enhance genetic diversity (by maintaining the separation between varieties), improve seed quality (for the same reasons) and have no impact at all on the livelihoods of poor farmers.
I hold no brief for or against GMOs, though I do think they have yet to prove themselves in the areas where they make the loudest claims. This is not about GMOs. It is about honesty. Any opponent of GMOs, however good the rest of their arguments might be, immediately loses my respect if they are also against GURTs.
Development and entrepreneurship in Africa
The company is just one part of Wade’s “comprehensive plan for Africa,” an anti-aid alternative to the Jeffrey Sachs vision.
A fascinating quote from a fascinating article on the Freakonomics blog, about three entrepreneurs in Africa. The woman whose quote I extracted above is Magatte Wade, and she’s the reason the story deserves a mention here. Her company — Adina for Life — came into being when she returned home to Senegal “and was disappointed to find that the traditional hibiscus drink of her childhood had been usurped by Western soft drinks”.
Hibiscus drinks are indeed a constant in many parts of sub-Saharan Africa, and hibiscus has been the focus of efforts to improve livelihoods by capitalizing on its popularity. Adina seems to be in a state of turmoil at the moment — with its US outlets suffering a crisis of identity and Wade apparently no longer associated with the company, at least in the US. But the larger point, that it is possible for Africans to make better use of their own natural resources remains valuable, and the other two stories in the Freakonomics story amplify that.
I wonder, though. Adina plunged into the cut-throat soft drinks market of the US. Why, when the stated goal was to replace sticky soft drinks in the home market? Wouldn’t that be enough?
Goats gnaw on geographic given
We’re used to thinking — or at least assuming — in agrobiodiversity conservation that genetic distance is a monotonically increasing function of geographic distance. It is, after all, a reflection of the great Waldo Tobler’s First Law of Geography: “Everything is related to everything else, but near things are more related than distant things.” And yet. Why should that necessarily be so for crops and livestock, so willfully and incessantly moved to and fro by people in all kinds of unpredictable ways?
A paper just out in Molecular Ecology in effect tests the First Law of Geography with goat genetic diversity data, microsatellites in fact. 2. Goat populations were sampled in 3-8 villages in each of 2-5 communes in each of 10 districts in the remote, mountainous, ethnically mixed Vietnamese province of Hang Giang, for a total of 492 animals. The genetic relationships among the animals were then analyzed.
To the surprise of the authors, the spatial structure of the overall population was poorly explained by simple geographic distance. The ethnicity of their keepers and the husbandry practices to which they were subjected did a much better job of predicting the genetic distance between goats. The most dissimilar goats were not necessarily the ones which lived furthest apart, but rather the ones which were kept in different ways by people of different ethnic groups.
So, if you wanted to maximise the diversity in a Vietnamese goat conservation programme, or your chances of hybrid vigour, you’d pick animals from different ethnic groups or production systems, and not necessarily from different ends of the country. Which is something that I remember sort of almost subconsciously doing when I was collecting crops, but it is nice to see it validated like this. I can’t remember offhand similar work on crops, but no doubt Jacob will set me straight soon enough. In the meantime, I revel in a rule proven.
