Eden makes a comeback of sorts

It was over two years ago that we blogged about attempts to bring back Iraq’s southern marshes, and the agriculture they supported. Now, via Wired, there’s evidence from NASA of at least partial success.

A United Nations Environment Program assessment of the Iraq marsh restoration in 2006 concluded that roughly 58 percent of the marsh area present in the mid-1970s had been restored in the sense that standing water was seasonally present and vegetation was reasonably dense.

Here’s what this (partial) reclaiming of the marshes looks like from space:

But serious concerns remain: the water used for reflooding may not be sustainable as the population recovers and expands its agricultural efforts, and the region may have already suffered an irreversible loss of species diversity.

Would be nice to know to what extent traditional agriculture is also coming back. Maybe this could be discerned from the aerial images? What has happened to local landraces in the meantime?

The Welsh pony story gets a happy ending, maybe

I mentioned earlier that DAD-Net is holding an e-consultation on threats to livestock diversity. There was a bit of discussion on the nature of the threats last week. One of the more interesting contributions came from Dafydd Pilling of the animal genetic resources group at FAO. He offered “an example in which the threat does not correspond exactly to any of the categories listed in the background document.”

The threat in question is the financial burden imposed on the owners of mountain ponies by the EU “horse passport” scheme. The story can be traced by visiting each of the following web pages in turn:

Passport threat to wild ponies

Time running out for wild ponies

Ponies saved from passport threat

Our little ponies facing extinction

Carneddau wild ponies

The problem goes back to 2004, and we noted it two years ago, but not the dénouement.

Three years ago the European Union passed a law that all such animals had to have a passport and be tagged. This costs £50 per animal, and at that time the ponies were only worth around £15 each so it just wasn’t going to be financially viable for us to keep protecting them.

Then seven local farmers got together, managed to secure Objective One funding and set up the Carneddau Ponies Association to fund and carry out this work.

…

We also want them classed as a rare breed, which would allow us to sell a group on one passport instead of individually.

Looks like livestock diversity is no less at risk from some EU regulation than the crop kind. Although Dr Pilling does add that “EU rules on ear tagging of cattle had been amended” when they were found to pose “a threat to extensive livestock management practices” in Europe. I’ll try to find out more about that one.

Russian agriculture as it was in living colour

English Russia is an “entertaiment blog devoted to the events happening in Russian speaking countries.” Quite often fun but not, you would have thought, likely to feature much of agrobiodiversity interest. And you’d be right. For 99% of the time at any rate. Because there was a post a few days ago with truly amazing colour photographs of the Russian Empire from a hundred years ago, and many show farming products and activities. They’re by Sergei Mikhailovich Prokudin-Gorskii, according to one of the comments, and he had a Library of Congress exhibition devoted to him in 2003, whose website is where it seems most of the images in the English Russia post originated. Well worth exploring. I wonder if some of these images could be used to compare with the present. For example, are these melons still to be found in Samarkand?
