Mapping aid

Thanks to CIAT’s Meike for news that

InterAction has just launched an interactive US Food Security Aid Map that provides detailed project-level information on food security and agriculture work being done by their member NGOs. The site can be browsed by location, sector, organization or project.

Here’s the map of agriculture projects: 1

As coincidence would have it, one of the projects is the orange-fleshed sweet potato work we mentioned in a recent post.

Searching on “agrobiodiversity” yielded nothing, but there were a few hits with “diversification.” Well worth exploring in a bit more detail. If only to identify places where some pre-emptive germplasm collecting might be in order.

More on the orange sweet potato story

The author of the orange-fleshed sweet potato paper I talked about a couple of days ago has kindly informed me that the answer to the question I posed is that the impact of the dissemination of these new varieties in Uganda has indeed been measured, but just hasn’t been published yet. There was apparently a big multidisciplinary study in 2007-2009 both in Uganda and Mozambique, and the results are due to come out in the near future. Good to hear, and many thanks, Robert. In the meantime, we have the following snippet from an IFPRI publication to whet our collective, er, appetite.

That elusive nutritional impact

Maybe it’s all the nutrition stuff going on here and at Vaviblog lately, but when I finally tried to catch up with a couple of papers from the recent special issue of the International Journal of Agricultural Sustainability on “Sustainable intensification: increasing productivity in African food and agricultural systems,” one thing struck above all else. And that was that both in the case of orange-fleshed sweet potatoes in Uganda and indigenous African vegetables in East Africa, there is still no evidence of a nutritional or health impact of adoption of that particular agrobiodiversity.

Ex ante predictions, sure. Economic impacts, plenty. Even in some cases nutritional impact of the same intervention (those orange sweet potatoes) in another place (South Africa). Maybe the impact on health and nutrition is there and just hasn’t been measured, or it has been measured but hasn’t been published yet. Or maybe it’s just too early for such an impact to have manifested itself. But when it comes to the specific agrobiodiversity cases of sweet potatoes in Uganda and traditional greens in East Africa, it seems to me that the biggest documented impact of so far has been on income.

Will someone out there set me straight? Please!

Oh, and since I’m at it, there’s a paper out by an old friend from the Pacific on a quick method of measuring some nutritional variables in sweet potatoes.

Nutritionist tells researchers what to eat shock

According to a report over at the Vaviblog, Bioversity’s nutritionist Jessica Fanzo was beset by questioners after her talk at the Vavilov Institute mentioned both the bad nutritional status of most Russians and the high nutritional value of some fruits and berries at the threatened Pavlovsk Experiment Station. She was bombarded with requests for advice. The Vaviblog’s correspondent reports:

One response stuck in my mind. Jessica was asked whether one couldn’t get all the vitamins and minerals one needs from pills. She said yes, but you have to get everything else from food, so why not the vitamins as well, by choosing your food better?

Especially if you like your potatoes processed and potable.
