Serious amateur breeding

Plant breeding need not be the high-tech, white-coated affair many people think it is. After all, for most of the history of agriculture, it wasn’t. Serious amateurs, in the true sense of the word, can make huge contributions.

We’ve written before about Rebsie Fairholm‘s pea breeding. Two others doing fine work are Rhizowen and Tom Wagner, and there are new accounts of both of their endeavours. Rhizowen modestly claims to have “the largest collection of oca germplasm in the whole county of Cornwall” as he brings us up to date with his efforts to breed a better Andean tuber. Tom Wagner’s speciality is the Solanaceae; we have him to thank for Green Zebra tomato, and many others. A current project is to breed a potato more resistant to late blight disease. The high-tech, white-coated gene jockeys are attempting the same trick, and Patrick at Bifurcated Carrots compares and contrasts the two approaches. While I don’t agree with everything he says, I do agree that a coordinated and widespread effort by amateur growers to assess Tom Wagner’s crosses is a fine idea. Patrick says that the UK trials of GM blight-resistant potatoes have a security fence that cost GBP20,000 and a 24 hour security guard. “If we had the money invested in the UK security fence alone, we could dramatically expand our trials not to mention offset some of our expenses,” he points out.

Where are the participatory plant breeding wallahs when you need them?

Rice, baby, rice!

Another contribution from Don Strong of UC Davis.

A fascinating video has appeared on Vimeo, “Filipino Rice Policy.” The topic of agricultural biodiversity is just below the surface of the narrative. The commentators are sophisticated economists and bureaucrats who tell an intriguing story of what amounts to a cult of rice in the Philippines. The crop and the commodity are sacrosanct politically, with secretive and lucrative importation monopolies. The commentary highlights the fact that even with a long history of premier educational and research institutions in tropical agriculture as well as high yields of rice, in few of the last 100 years has Philippine production been sufficient to meet domestic demand. The popular image of rice as the mainstay to the economy and the officially encouraged yearning for rice self-sufficiency are misleading, according to the narrative. First, the country simply lacks the physical land for rice self-sufficiency. It cannot compete in volume with the vast rice-growing areas in mainland Asia (many of which Philippine institutions fostered during the heady days of the early Green Revolution). Also, rice is just one among many crops and commodities in the diverse agricultural economy of the Philippines.

The main theme is that the government importation monopoly for rice is part and parcel of high level corruption that actually threatens food security. It is claimed that some 40% of monies dedicated to importation end up in the pockets of privileged insiders — “cronies” — rather than in the rice bowls of the poor; though the the poor are the prima facie rationale for the importation monopoly. The argument is made that were rice importation opened up, the diversity of agricultural production would increase as farmers made market-based decisions rather than monopoly-based ones; other crops and animals produce more income as well as a richer life for rural agriculturalists. This video is a professional product, well edited, and lively. The dialogue is nuanced and often waxes into advanced political economics. It would be a great supplement to graduate courses in agricultural economics, development, and environmental science. A highlight is disagreement with the theme by one commentator who fears that an end to the monopoly could bring collapse to the rice market, disaster to the country, and the downfall of the politicians who broke the monopoly. While breaking the monopoly would certainly be politically perilous, the Philippines is not among the largest global players in rice. It seems unlikely that their monopoly could be much of a factor in the global rice market.

An important sub theme of the video is how the pro-natalist policies of the Philippines have made food security an increasingly difficult goal. These populations are now much larger, still growing, and a much greater challenge to both poverty reduction and future food security than they were in 1960 when the Green Revolution widely lowered death rates and led to rapid population growth. Persistent poverty of a segment of the agricultural sector is a feature shared by many of the rice economies.

In larger perspective, the Philippines are not alone with such myths. The quixotic propaganda of rice self-sufficiency for the Philippines is analogous to that of oil self sufficiency for the US so prominent in slogans such as “Drill Baby Drill.”

IPBES — IPCC for biodiversity — agreed

I suppose this is a big deal. After a couple of years of negotiations, countries agreed in Korea yesterday to go ahead with the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services — IPBES. You can read about it at Nature and the Guardian. Neither says anything about agriculture or wild relatives, although Professor Bob Watson, vice-chair of IPBES, says it will focus on “poverty alleviation, human well-being and sustainable development”. So far, so unsurprising. According to Nature, one of the problems for countries to agree to create IPBES was its scope, and it has been limited to “new topics” in biodiversity and ecosystem science.

That means we probably can’t look forward to an authoritative estimate of the extent of genetic erosion. Darn.

A plan to keep cacao alive in Ivory Coast, but for how long?

A long article in the Financial Times a few days ago described the woes of the Ivorian cacao industry. Fundamentally, it’s down to old, and therefore increasingly sick and unproductive, trees. And the quantity squeeze is forcing farmers to compromise on quality.

All this is important because Ivory Coast accounts for 39% of the world’s cacao production. A “chocolate crisis” is looming. And companies like Nestlé are worried. They employ a small army of agronomists, breeders and extensionists just to guarantee their supply of raw materials.

Hence their “Cocoa Plan” to replant 12 million trees (out of a total of 2 billion in the country) over the next decade at a cost of almost $100 million. A monumental task for a crop grown by hundreds of thousands of smallholders. The article does not go into detail on the varieties that are being used in the replanting, beyond saying that they are not GMOs and that the plantlets

…have already been nicknamed “Mercedes” for their supposedly upmarket quality. “They grow very, very quickly,” says Jebouet Kouassi, a 43-year-old who runs one of Nestlé’s nurseries in Ivory Coast.

Neither, alas, does the Cocoa Plan’s website. Elsewhere I found this:

The seedlings will be produced from high-yield and resistant varieties by somatic embryogenesis, which produce replicas of high performance cocoa trees, with high yield and high resistance to disease.

I hope that the narrowing of genetic diversity that this approach seems to imply will not store up problems for the future.
