Featured: Feed databases

Alan Duncan of ILRI responds to Luigi’s “could do better” on a database of forage in sub-Saharan Africa.

There are various “nifty ILRI tools” in development and I’m not sure that the SSA feeds database is the right one for what you’re suggesting. … The key issue is choosing technologies that deal with the major constraints: feed scarcity, feed quality and feed seasonality. And it’s also about much more than nutritive value – there are many other characteristics of feed technologies which will affect their suitability in different contexts. We do envisage a suit of tools to deal with some of these issues and will keep posting progress on the fodder adoption blog.

Good to know.

Sorghum and ethnicity in Africa

Ever since I contributed to A methodological model for ecogeographic surveys of crops, and suggested that collectors should do this, I’ve been waiting for the time when it would be easy — or even possible — to map the distribution of conserved germplasm on top of cultural, ethnic or language boundaries. The problem has been that maps of such boundaries, 1 though available in various printed formats, have not been much digitized. Or at least I hadn’t come across them. Until I happened on a blog post about the Center for Geographic Analysis’ (Harvard University) WorldMap, an open source web mapping system. The layers provided include one called Ethnicity Felix 2001, which “consist of polygons and labels depicting ethnicity information based on the ‘People’s Atlas of Africa’ by Marc Felix and Charles Meur, Copyright 2001.” Perfect, I thought.

Sorghum accessions (Genesys) and ethnic groups in Uganda.
Well, not so fast. It was not altogether easy to download a shapefile of conserved African sorghum landraces from Genesys that would upload into WorldMap, plonk it on top of Ethnicity Felix 2001 and produce a shareable map. Not easy, but possible. It took some time and some divine intervention from Robert, but I do now have a map of African ethnic groups and sorghum collections that other people can have a look at. At left you have a snippet showing Uganda to whet your appetite. So now, in addition to things like ecogeographic gaps in collections, made possible by global climate surfaces, we can also begin to investigate cultural gaps.

Don’t forget the open Mendeley group for the papers we link to here. Even if you don’t use Mendeley, you can subscribe to the RSS feed from the group and get stuff that way.
