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?

Cheers

I can’t believe I forgot to include news of the President’s homebrew in the list of my favourite agrobiodiversity stories of the past few weeks. I suppose it was all done by the Obama campaign as part of a complicated social media strategy to deflect attention from the Republican convention, but I don’t care. I like that the hop varieties involved, Kent Goldings and Fuggles, have venerable, and not uninteresting, histories.

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:

Where Kasalath rice landrace really comes from

The conversation about Kasalath rice continues, with some actual information about the accession in question. The back story has kinda sorta made its way into the mainstream media too. Reuters published the picture below yesterday (30 August).

A scientist locates the rice variety kasalath inside the gene bank at the International Rice Research Institute in Los Banos, Laguna

“A scientist locates the rice variety kasalath inside the gene bank at the International Rice Research Institute (IRRI) in Los Banos, Laguna, south of Manila August 30, 2012. A team of scientists from the IRRI, led by Sigrid Heuer, say that they have discovered a gene called PSTOL1, or Phosphorous Starvation Tolerance, which increases grain production by 20 percent by enabling rice plants to grow stronger root systems for better intake of phosphorus, an important but limited plant nutrient. The discovery will help poor rice farmers grow more rice for sale, even while working on phosphorus-deficient land, according to Heuer.”

I guess we’ll just have to take Reuters’ word that the scientist is indeed locating Kasalath and not some other sample.
