India clones the buffalo, solves the milk problem

There was a wonderfully informative article on buffalo cloning in Northern Voices Online — tag line: “Connecting Indians Globally” — a few days back. Here’s a few of the interesting tidbits that it serves up (though I haven’t yet verified the information, I should add). A buffalo has been cloned in India for the second time, this one by the name of Garima. The first survived only a few days. India is the world’s largest milk producer (15% of total global production); 55% of that is contributed by buffalo. India’s first cross-bred cow, named Jill, was produced in 1909 at the Imperial Institute of Animal Husbandry Bangalore, by crossing an Ayrshire with the local Haryana breed. And so on.

Now, in such a well-informed and data-laden article, it is surprising not to hear the other side of the story as well. Why not say something about the importance of conserving, continuing to use, and improving local breeds, while all this cross-breeding and cloning is going on? Why not mention the work of the National Bureau of Animal Genetic Resources? After all, it will be a long time before cloned elite buffaloes are contributing to that 55%.

Shifting baselines and genetic erosion

A posting from the good people at Bioplan ((A mailing list on biodiversity policy issues set up and maintained by the UNDP and UNEP.)) forwarded to me by my friend Mary Taylor has just alerted me to an article over at Mongabay which would probably have eluded me as I’m on the road at the moment and not checking the feedreader very systematically. So thanks, Mary.

The post is about the “shifting baselines” theory, apparently an influential concept in conservation thinking during the past decade and more but one that alas I hadn’t come across. It proposes that…

…due to short life-spans and faulty memories, humans have a poor conception of how much of the natural world has been degraded by our actions, because our ‘baseline’ shifts with every generation, and sometimes even in an individual. In essence, what we see as pristine nature would be seen by our ancestors as hopelessly degraded, and what we see as degraded our children will view as ‘natural’.

And if people can’t register the loss, how can conservation be made important to them?

I’ll leave you to read the details of the paper at Mongabay. It’s about the perception of changes in the local bird fauna among 50 rural Yorkshire villagers, compared to the “reality” revealed by the results of regular ornithological surveys. Suffice it to say that the authors found evidence of both “generational amnesia” (when people fail to pass knowledge down from generation to generation) and “personal amnesia” (when people forget how things used to be earlier in their lives).

Is this relevant for studies of genetic erosion in crops? For plants, including crops, there is a pretty good way of documenting changes in distribution, abundance and even genetic diversity, and that’s by comparison of the present situation with herbarium specimens and genebank samples. And old seed catalogues have also been scoured for evidence of loss of varieties of fruits and vegetables in Europe and the United States. I’ve suggested myself in the past that these are all valid, complementary approaches to the estimation of genetic erosion, though they all have their shortcomings. But I can’t think off the top of my head of a study which has combined making historical comparisons with asking people about how many varieties of a particular crop they used to grow, to gauge the accuracy of their recollections, though my own recollection of the literature may be faulty too! It seems to me that farmers are more likely to accurately recollect the crop varieties they used to grow than almost anything else, including the birds that fly around them, especially if you get a group of them together to discuss the issue, but it would be an interesting thing to test.

One of the authors of the paper does mention specimens in passing in his Mongabay interview.

“If the issue is with personal amnesia, just talking to people and triggering their memories about how things were, perhaps with the aid of props like photos or old specimens, will help them to ensure that their perceptions of change are accurate,” Milner-Gulland says.

That’s as part of a discussion of the “increasingly creative” ways of “finding data regarding past conditions that may no longer be remembered” that certainly has relevance for crops.

“One author (Julian Caldecott) used school meal records from remote village schools to reconstruct wild pig migrations in Borneo. There are many authors now using historical records and archeological remains, for example in charting the changes in fish stock compositions in the North Sea over thousands of years. Other people use contemporary accounts from eye-witnesses, while still others use scientific methods like pollen analysis, which can go back far beyond written accounts.” Milner-Gulland says, adding that “the important issues involve recognizing and accounting for sources of bias in the records that you use.”

And that goes for the knowledge of farmers too.

Pawnee corn pix

Our friend Karen Williams at the USDA writes:

The story of the Pawnee maize is fascinating! You have probably seen the display cases in Beltsville of the collection of maize varieties. Years ago, David and I were involved in getting all the samples photographed. Attached are photos of the 3 samples identified as Pawnee varieties. You are welcome to post these to your blog, if you think they are of interest.

[nggallery id=3]

Unfortunately, the display cases are so old (1930s or earlier) that no documentation on their history exists. We don’t even know who collected them. They predate the NPGS so there are no corresponding germplasm samples.

So lets really push our luck here, and ask whether anyone out there has any information about the USDA’s display case collections?

More on the rescuing of Pawnee corn

Tom Hoegemeyer very kindly replied to my query about rescuing Pawnee corn, and agreed to have his email published here. Thanks, Tom, and very best wishes with your work with the Pawnee.

I was out at the Pawnee homecoming and have been attempting to help them grow some of their old varieties (some had been in storage in homes for years and has low germination and vigor). We have been successful with some varieties, but others appear to be dead. I have also visited with several of the Pawnee “corn keepers” concerning the varieties, their culture and history. Some of the Pawnee varieties may be listed under other names as well—the Arikara are blood relatives, having separated from the Pawnee, moved north and settled on the Elkhorn and Missouri Rivers. Also, their history of inter-tribal warfare lead to the “theft” of some of their varieties by other neighboring tribes—Oto-Missouria , several Sioux groups, and Omaha in particular. I would not be surprised if the same, or nearly so, varieties may have been collected from other areas. One way to test this would be by DNA, as I have been given samples of a couple of varieties we have had no luck in growing, even with seed treatment, surface sterilization, ATP supplementation, embryo rescue, etc.

Some history as to why I am involved: One of my technicians has an uncle who is a photographer and writer for “Nebraskaland” magazine, and he asked his nephew and me if we would help them recover varieties.

I had done some looking in GRIN, but there seems to be little information, sourcing for Pawnee varieties. The issue is not the fault of GRIN, but the fact that the Pawnee were moved to Oklahoma around 1877. The white settlers brought their seed with them from the east (e.g. Illinois) and the Pawnee varieties were not kept locally. And apparently, they had difficulty growing them in Oklahoma. So other than a few plants/ears from their home gardens, there is no direct seed source. As soon as I have time, I intend to do some searching in GRIN for varieties that may be related to these recalcitrant Pawnee varieties. I would be very open to help, advice, etc. Some of the varieties that have been regrown trace to only a few plants, so there is a sampling/inbreeding issue. Even for these it may be helpful to see if other related sources exist in GRIN.

The Pawnee have a serious issue with obesity and Type II diabetes. They feel that if they could return to their original diet, perhaps there would be fewer health issues. (I suspect that the gardening and hiking to hunt large and small animals would be more important.) There is also a cultural/emotional/religious aspect to their desire to recover these varieties, so I have found it interesting to try to help!

Scientifically, I think it would be interesting to do a small study of these native varieties to analyze their relationships, and the relationship of them to the “Corn-belt Dents”, which as I understand were mostly developed east of the Mississippi. I suspect that there may also be interesting alleles in these.

The Pawnee trace their heritage to the proto-Aztecs, and there is some linguistic evidence for that. Apparently a group moved northeast to present day East Texas and Louisiana, and are known as the Caddo. Some of the Caddo moved north to Kansas/Nebraska and became the four tribal groups of the Pawnee, and the linguistic evidence for their Caddo connection is VERY strong.

Before this situation came up, I had never thought of using genebanks for this sort of cultural purpose. I found several of the Pawnee very interesting. They sincerely feel a connection to the land, fauna and flora. Several of the corn varieties are associated with rituals, and all of them are involved in “sacred bundles”. They stored artifacts, momentos, historical items and specific corn varieties in the bundles. They kept about a dozen varieties each of corn, beans, and squash/pumpkin, and always planted each corn variety at distances of about 500 paces—near the modern seed certification isolation distance! When the stars were in the correct position each spring, the corn was planted with a ceremony. After it reached about knee high, they hoed it to control weeds, followed by a ceremony, after which they would leave for the summer buffalo hunt. Late summer/early fall they would return to their permanent log and earthen houses and start the crop harvest and storage. After harvesting (and more ceremonies) they would go out on the fall hunt, then return to their homes for winter.

Different corns were used for different foods, including a popcorn. I have found the whole experience—reading and meeting the “corn sisters”, and learning a bit about the culture fascinating.

We are what we crop?

The first installment of a promised two-part coffee-table conversation from Jacob van Etten.

Some time ago, I promised to write something about if and how crops shape societies. ‘Environmental determinism’ and ‘technological determinism’ are not popular theories in the social sciences these days. ‘Crop determinism’ is in a way both these types of determinism in one, so doubly despicable, I guess.

But I like deterministic theories. For one thing, they make for good talk around the coffee table. Ellen Semple’s environmental determinism is classic and moreover produces grand prose:

Man is a product of the earth’s surface. This means not merely that he is a child of the earth, dust of her dust; but that the earth has mothered him, fed him, set him tasks, directed his thoughts, confronted him with difficulties that have strengthened his body and sharpened his wits, given him his problems of navigation or irrigation, and at the same time whispered hints for their solution. She has entered into his bone and tissue, into his mind and soul. On the mountains she has given him leg muscles of iron to climb the slope; along the coast she has left these weak and flabby, but given him instead vigorous development of chest and arm to handle his paddle or oar. In the river valley she attaches him to the fertile soil, circumscribes his ideas and ambitions by a dull round of calm, exacting duties, narrows his outlook to the cramped horizon of his farm.

That’s by way of prelude to her famous thesis that monotheism is the product of desert landscapes.

Up on the wind-swept plateaus, in the boundless stretch of the grasslands and the waterless tracts of the desert, where he roams with his flocks from pasture to pasture and oasis to oasis, where life knows much hardship but escapes the grind of drudgery, where the watching of grazing herd gives him leisure for contemplation, and the wide-ranging life a big horizon, his ideas take on a certain gigantic simplicity; religion becomes monotheism, God becomes one, unrivalled like the sand of the desert and the grass of the steppe, stretching on and on without break or change. Chewing over and over the cud of his simple belief as the one food of his unfed mind, his faith becomes fanaticism; his big spacial ideas, born of that ceaseless regular wandering, outgrow the land that bred them and bear their legitimate fruit in wide imperial conquests.

Ellen Semple was a geographer who worked in the first half of the 20th century. Now, for much of the rest of that century geographers have been busy rebuking such coffee-table theorizing. Carl Sauer, one of the founding fathers of modern geography, who wrote a great deal about agriculture, said that cultures and environments influence each other. It is all about how we learn about our environment and acquire the skills to make the earth a suitable habitat for ourselves. Different cultures do that in different ways, independent of the environment they live in.

That is a good point, of course, but there may be certain general tendencies in human adaptation to the environment — parallel evolution, so to say. At least, one-cause theories open our eyes to certain patterns we hadn’t noticed before and which demand an explanation. Personally, I don’t believe that monotheism has much to do with deserts or horizons. But another of my favourite theories in this category is perhaps more plausible.

Slicher van Bath, a Dutch historian, argued that democracy has to do with wet soils. ((B.H. Slicher van Bath. 1948. Boerenvrijheid (Groningen/Batavia), inaugural lecture at the University of Groningen.)) The argument goes like this. On wet soils in Europe (peat soils in the Netherlands, the UK and elsewhere, Swiss valleys), there are few agricultural alternatives to livestock. In times of need, livestock farmers sell a cow or a sheep. The following year, new animals are born, so they can recover from the loss. In this way, farmers retain their independence and remain on an equal footing. But if you are a crop farmer, you may, by contrast, be forced to sell some land. Land, unlike livestock, doesn’t reproduce. Some farmers will accumulate a lot of land and start to dominate. A less democratic society is born.

Livestock countries in Europe are among the most democratic ones, so this makes sense, it seems to me. Perhaps some jobless mapper could further test it by doing a nice overlay map of soil wetness and democracy indices.

Mountain valleys also shape very particular kinds of societies. Another of my favourites is an article by Robert Rhoades and Stephen Thompson about the remarkable parallels between ‘adaptive strategies’ in mountains. ((R.E. Rhoades & S.I. Thompson. 1975. Adaptive strategies in alpine environments: beyond ecological particularism. American Ethnologist X, 535-551.)) Strong communal decision-making and fragmented landholdings are found in the Andes, the Himalayas, as well as in the Alps. Also, both the Himalayas and the Alps have traditionally drained off their ‘surplus’ males as mercenaries. I wonder: what is the Andean variant of the fierce Gurkhas and the quaint Swiss guards?

And what about crops then, you ask? Stay tuned for Part Two…
