Wikiseedia: what is it?

Seedpod There’s a long and detailed message from the folks at WorldChanging about something they call SeedPOD. It isn’t clear exactly what this resource will be. A sort of information exchange, but also a network for exchanging seeds and maybe too a platform for sharing experiments and results in more sustainable agriculture. As they describe it:

an imagined toolkit to keep seeds moving, farmers thriving and communities fed in the face of massive environmental change. Perhaps it will trigger some interesting thinking out there: at very least, we hope you find it briefly diverting.

All this seems to be organized through something called the Wikiseedia, but as far as I can see there is no link to this fabulous beast. Go to www.wikiseedia.com, however, and you see a bare bones installation of a wiki (a special kind of web site that anyone can contribute to and edit) that contains no content (yet?) and that has not been changed since 5 March 2007. WorldChanging’s post is dated 27 April.

There’s something happening out there. What it is ain’t exactly clear. But it will bear watching. At least, I hope it will, because it sounds really exciting.

Perk up people, it’s about your survival

Someone called Bradford Plumer, whom I had not previously come across, has a longish post asking why people don’t seem to care about the ongoing mass extinction and wishing that more writers on the subject “would really hammer home why humans should care about the loss of biodiversity”. Funnily enough, he couches his entire argument in terms of natural processes and ecosystems and what their collapse might mean. And he quotes agriculture, and especially monoculture, exclusively as problem, not solution. But the only example he gives of the sort of example that might might “get people to perk up” is the possibly looming pollination crisis caused by a shortage of bees.

Until there is a wider understanding that agriculture is part of nature, and not separate from it, and that we humans are far more dependent on the food providing services of agriculture than on any other ecological service, I doubt that there’s going to be much perking up anywhere.

There’s not a lot of understanding of that in Brad’s posts or the comments on it, but I live in hope.

Welsh pony in trouble?

A long article in icWales, the self-described “national website of Wales,” details the predicament of the local pony breed. Once an important part of everyday rural life – and indeed industrial life, due to their use in coal mines – more recently a children’s trekking pony, there is now limited demand for the breed. Wild herds have thus declined dramatically, no doubt resulting in genetic erosion. Does it matter? A resounding yes echoes around the hills.

Indian potato chips

Indian potato growers are turning to a new, low-sugar variety of potato because it is better for making chips (crisps if you’re British), for which there is rapidly increasing demand. Would be interesting to monitor the effect on “local” varieties, no?

Magnolias in trouble

The Global Trees Campaign says that 131 of 245 wild Magnoliaceae are threatened worldwide. According to this press release from BGCI:

The significance of this potentially catastrophic loss lies not only in the threat to the genetic diversity of the family, but also because they are a highly sensitive indicator of the well-being of the forests in which they are found. Magnolias are among the most ancient groups of flowering plants and have long been cultivated by mankind.

You can download a PDF of the new Magnoliaceae Red List. The publication of the red list has been widely covered by the press, including New Scientist. Many species have medicinal uses and some are used for food.

Predictably, protected areas are highlighted as an important approach to the conservation of these species, particularly in their hotspot in southern China. A separate new study

concludes that protected areas are necessary for preventing the loss of species due to climate change – provided that shifts in species’ ranges are factored into early analysis of whether to expand current protected areas or create new ones.

The new red list includes distribution maps of all magnolias, clearly an important first step.
