Organic farming: what is it good for?

Organic produce and meat typically is no better for you than conventional food when it comes to vitamin and nutrient content, although it does generally reduce exposure to pesticides and antibiotic-resistant bacteria, according to a US study.

Organic farming is generally good for wildlife but does not necessarily have lower overall environmental impacts than conventional farming, a new analysis led by Oxford University scientists has shown.

Time for a meta-meta-analysis?

Urban agriculture gets its 15 minutes

The World Urban Forum is taking place down in my home town this week. That I suppose was what provided at least part of the impetus for the United Nations Standing Committee on Nutrition (UNSCN) to issue a statement on the Nutrition Security of Urban Populations. Not to be outdone, FAO has a publication out too, Growing Greener Cities in Africa, touted as the “first status report on urban and peri-urban horticulture in Africa.” A cursory glance doesn’t reveal much on diversity in these documents, but this is an issue that’s always intrigued me. Could cities act as magnets for crop inter- and intraspecific diversity? After all, they have lots of micro-niches, and have been attracting people from all over for decades, who could have come with their seeds. Is it possible that varieties could still be grown in cities after they’ve disappeared in their native areas? Or at any rate that crop diversity in a city is higher than in the surrounding countryside? Sometime ago we did a small survey of sweet potato diversity in Nairobi roadside verges that seemed to suggest that the menu of varieties was at least somewhat different from what was available in nearby rural areas. Should write that up one day. Anybody know of similar studies?

What I read on my summer holidays

Yeah, summer is over and I’m back at work. Maybe you noticed I haven’t contributed much here in the past month or so. Or maybe you didn’t. Jeremy kept up a steady stream of agrobiodiversity nuggets pretty much all through August. But my lack of activity on the blog doesn’t mean I haven’t tried to keep up, as you would know if you followed us on Facebook, Twitter or Scoop.it. Anyway, for those that don’t, and would like to catch up on my summer reading, here is, in nibble form, what caught my eye during the past month or so:

Sovereign rights raises its ugly head

Where’s my guide to the netherworld of genebank databases when I need him?

I need him to make a somewhat snarky point. A recent commenter objects to the characterisation of Kasalath, the “wild” rice that’s been in the news lately, as Indian.

Kasalat is actually a Bangladeshi variety not Indian. In Bangla it means Kacha Lota or green shoot. From time immemorial it has been grown in the eastern district of Sylhet of Bangladesh from where it might have gone to India…. [I]t is just plain wrong to describe it as an Indian variety.

But as Wikipedia tells us,

The history of Bangladesh as a nation state began in 1971, when it seceded from Pakistan. Prior to the creation of Pakistan in 1947, modern-day Bangladesh was part of ancient, classical, medieval and colonial India.

So when was Kasalath collected? Or, to put it another way, what was the name of the nation state in which the place that Kasalath has grown from time immemorial found itself at the time someone collected it?

That’s what databases are for, right? IRIS, The International Rice Information System, has 12 entries for entities called Kasalath, three of them at IRRI and one in India. I couldn’t find anything as dull as an accession date for any of them. IRIS is a bit unfriendly, 1 although thanks to it I did also discover that Kasalath is one of about 400 varieties selected to form a Rice Diversity Panel. Until Beatrice returns from his travels, or logs on, that’s the best I can do.

And the point, of course, is to suggest that the very idea of a variety grown since time immemorial belonging to any Johnny-come-lately nation state is, alas, a cruel joke.
