Brainfood: Striga, Rice, Fish, Biofortification, Ecosystem functioning, Intercrops

OK, so we’re trying an experiment, siphoning off Nibbles about research, often in peer-reviewed journals, into their own hi-falutin’ cookie jar. We’ll probably publish once a week. And being here doesn’t mean we won’t revisit them later.

So what do you reckon? Is this worthwhile?

Heirloom seeds exposed

The New York Times carried a long article on heirloom seeds on Wednesday. It is both balanced and iconoclastic, but anyone reading in Europe, might, like me, have raised a metaphorical eyebrow at this paragraph:

But the “universities have basically shut down all their programs for home gardeners,” Mr. Gettle said. “Most plant breeders are owned by a few large seed companies. I wish they would develop more things for the home garden.”

You don’t get to be a large seed company by paying any attention to home gardeners who, in any case, say they want to be able to save their own seeds from year to year. Nevertheless, the NYT went on to talk about some of the backyard breeders and small, regional seed companies that are doing precisely that, developing varieties for home gardeners and smaller commercial growers. In the US, and many other places, the market determines what people can get. If the marketing claims made for heirlooms are sketchy, the New York Times will find people to say so. And if large seed companies are failing to satisfy some market segments, other suppliers can try to do better.

European growers and breeders still don’t have that luxury. Directives on conservation varieties do nothing to encourage future breeding efforts, they merely permit old varieties to be marketed under certain conditions. In England and Wales, at any rate, new varieties will still need to be formally listed on the Common Catalogue. As far as I know, the conservation directives so far have been implemented only in Ireland, ((Please correct me.)) and a report assessing the value of the directives, due in late 2010 or early 2011, has not surfaced either.

Anyone in Europe wishing to grow unregistered varieties — whatever their motivation, and no matter how misguided they may be — has to find other channels. Of which, I’m glad to say, there seems to be an increasing number.

Training manual for GIS analysis of agrobiodiversity data

Great to see “Training Manual on Spatial Analysis of Plant Diversity and Distribution” finally out, courtesy of Bioversity International. Well worth the wait, and not just because I get called a pioneer in it. Congratulations to Xavier Scheldeman and Maarten van Zonneveld for addressing a very important need.

This manual has been published as a result of the increasing number of requests received by Bioversity International for capacity building on the spatial analysis of biodiversity data. The authors have developed a set of step-by-step instructions, accompanied by a series of analyses, based on free and publically available software: DIVA-GIS, a GIS programme specifically designed to undertake spatial diversity analysis; and Maxent, a species distribution modelling programme. The manual does not aim to illustrate the use of each individual DIVA-GIS and Maxent command/option, but focuses on using GIS tools to help answer common questions relating to the spatial analysis of biodiversity data. Throughout the manual, the importance of proper sampling is stressed; however, it is beyond the scope of the document to elaborate on sampling theories. The manual also does not discuss the statistical analysis of diversity data in detail; instead, when statistical methods and programmes are mentioned in the text, the reader is referred to alternative reference materials for further information.

Promote better nutrition and self-sufficiency with a few clicks

The Cooperative Society in the UK recently launched a scheme called Join the Revolution. People submit projects and other people vote for them. Winners get money — GBP 5000 — towards their project.

A project I already knew about alerted me and asked me to vote, which I have done even though, to be perfectly honest, the proposal didn’t exactly set the heart aflutter. There’s another project in similar vein that is currently doing better, so I won’t link to that, but it isn’t hard to scan all the submissions and pick the revolution you would most like to foment. In fact, you’re allowed to vote for as many as you want, which seems a little odd. On the other hand, having clicked the few times needed to register on the site, it seems wasteful not to vote often.

There are some videos about projects which, I think, were funded in an earlier round. Here’s one I could relate to.

Are there any other Coop-funded revolutions we should promote? Other competitions?
