Farmers’ market fails to market diversity

Wandering around London on Friday, we came across the Pimlico Road Farmers’ Market. A couple of dozen stall selling everything from fruits and vegetables to cheese to all kinds of meat products, mostly sourced locally, meaning within 100 miles of the M25, the motorway that goes all the way around London. Friendly people. Beautiful produce, beautifully displayed. All impeccably organically certified — signs to that effect were everywhere. Made artisanally, naturally, according to traditions which no doubt trace their origins back to the mist-shrouded times of, well, the last Tory government, probably. And yet, and yet…

Apart from one stall selling tomatoes

and another one selling apples and apple products

there was really no indication that agrobiodiversity was in any way valued, either by the sellers or buyers.

None of the stalls had more than one or two varieties of any of the fruits and vegetables on display. Ok, I thought, fair enough, we’re not dealing with a huge catchment area. But there was not even any mention of variety names on the labels. Maybe they’re all rather boring commercial cultivars and breeds, and the stall owners don’t want to draw attention to that fact. The European Union doesn’t make it particularly easy to grow heirlooms, as we’ve pointed out here before. And indeed a brief chat with a couple of stall holders did in fact reveal that none of the veggies on display were particularly noteworthy local varieties. Pity. It seems that the fact that produce is organically grown is an immeasurably more important selling point than its status as an ancient landrace, at least in this market in an affluent part of London, which I found surprising. I wonder if some enterprising student is making a study of all such markets across London.

Excellent pork pies though.

The end of the line for Egypt Baladi?

The controversy over the Egyptian pig cull is turning very nasty.

There are estimated to be more than 300,000 pigs in Egypt, but the World Health Organisation says there is no evidence there of the animals transmitting swine flu to humans.

Pig-farming and consumption is concentrated in Egypt’s Coptic Christian minority, estimated at 10% of the population.

Many are reared in slum areas by rubbish collectors who use the pigs to dispose of organic waste. They say the cull will harm their businesses and has renewed tensions with Egypt’s Muslim majority.

The Domestic Animal Diversity Information System hosted by FAO records only one pig landrace in Egypt, called Egypt Baladi, from بلاد which just means land or soil. “Baladi” means something like “of this land”. The pig has a long history in Egypt, but I can’t find any information on its genetic affinities. If the total cull goes ahead, will a unique, ancient landrace be lost forever?

Organic farms mapped

There are 10,159 organic farms in the US 1 and, unlike farms in general, they are distributed around the country in a series of distinct hotspots. I know this because the NY Times did its usual wondeful graphics number on the USDA’s numbers. I wonder what Paul Krugman would have to say about these particular business clusters.

LATER: Oops, too fast on the old “Publish” button. If I’d waited to go live with the above until after browsing through my feed reader, I could have added that Food & Water Watch have a complementary map of factory farms in the US. Which I found out about via a story in the Atlantic Food Channel that was actually about something different, the global provenance of food.

LATER STILL: Alas, the map of organic farm distribution bears more than a passing resemblance to that for greed. Kinda.

Botanical garden database heaven

An email alert from the good folks at Botanical Gardens Conservation International (BCGI) tells me they have spruced up their website. And the website in turns reminds me that May 18th is Plant Conservation Day, and we should probably do something about that here.

But the main reason for the alert is to draw our attention to two online databases: PlantSearch and GardenSearch.

PlantSearch enables users to locate rare or threatened plant species in cultivation around the world. This database is compiled from lists of living collections submitted to BGCI by the world’s botanic gardens. The database presently includes over 575,000 records representing almost 180,000 taxa from 692 gardens.

And you can find a garden anywhere in the world using GardenSearch, with over 2658 records. We’re working on an interactive botanic garden mapping tool too…

There’s a filter for crop wild relatives. Seems to me the botanical gardens community may be a bit further down the road out of database hell than the world’s genebanks.

“A man is related to all nature”

Mark Easton, the BBC’s home editor, starts a blog post today with this quotation from Ralph Waldo Emerson as an introduction to making the point that the protected area of Wicken Fen in Lincolnshire is… 2

…the product of complex interaction between plants, birds and animals. And fundamental to its existence were the apparently destructive activities of one animal in particular: man.

Well, that could be said of a lot of landscapes around the world. Even, possibly, as is increasingly argued, places like the Amazon, which until recently was generally regarded as nature in its most pristine state.

But to go back to Wicken Fen, which, incidentally, I remember very fondly, having done a certain amount of fieldwork there as an undergraduate. It seems “the [UK] government, anxious to protect another fragile habitat, the peat bog, wants 90% of composts and soil improvers to be peat-free by next year.” So peat digging was banned at Wicken Fen. Good, you say? Well, not so much. This change in a practice that has been going on for centuries has contributed to the local extinction of the rare fen orchid. And not only that, the fen violet too, probably:

The rural culture – which had cut the sedge for roofing and animal bedding – disappeared and the fen violet along with it. Its seeds may still survive in the peaty soil and occasionally a rare plant will push through the surface if the land has been disturbed, but the violet has not been seen at Wicken for more than a decade.

And the swallowtail butterfly and Montagu’s harrier as well, due to past changes in management practices.

So what to do. As Mark Easton says, nowadays “conservationists ape the principles of the ancient harvesters to protect what is left of the fen.” But not all agree. “Instead of trying to counteract nature, man should work with it.”

This is a much less predictable approach to conservation but, it seems to me, it is a philosophy more in tune with an acceptance that man is not god. We are part of nature too.

Fair enough, but what if you are managing a protected area specifically for a particular species of value? Say an important crop wild relative. I can imagine a situation where you might want to be a bit more intensive in your intervention, and a bit more predictable. Which is one of the reasons why I don’t think that “conventional” protected areas such as your average national park will ever be much use for CWR conservation, except by chance.

Incidentally, there’s a couple of CWRs at Wicken Fen, according to the great mapping facility on its website. Here’s where you can find Asparagus officinalis, for example: it’s that red square right at the top.
