Featured: Livestock data jungle

Tim Robinson updates us on livestock data at FAO:

…We had, of course, been working on the collection of the underlying livestock statistics, and the spatial modelling to produce the maps, for many years prior to them being published on the FAO website … but that is all quickly forgotten when they are re-distributed by a third party.

For your information, we have been beavering away since then, collecting more recent and detailed sub-national livestock statistics and disaggregating these using a slightly modified modelling approach, and 1 km multi-temporal, Fourier-processed MODIS imagery from the University of Oxford…

Global datasets coming soon, apparently. We’ll keep you posted.

Featured: Old Tanzanian sorghum

Mark Nesbitt knows who the Director of Agriculture is Tanzania was in 1934:

The sorghum collection – all 956 accessions – was acquired by J.D. Snowden while working on his 1936 book (still in print!) “Cultivated Races of Sorghum”. It’s a perfect example of a collection that 20 years ago would have seemed useless (old seeds, mostly dead) but thanks to new techniques (DNA analysis) suddenly looks very interesting as a record of landrace distribution before the Green Revolution.

So, any gene jockeys out there interested in extracting DNA from old seeds? Just for information, there are 1058 sorghum accessions from Tanzania in Genesys. How much can it cost to run a bunch of microsatellites on 2,000 samples?

Featured: Organic breeding

On the lack of varieties selected to perform well under organic agriculture, David Tribe (aka GMO Pundit) asks:

Why not use the seed industry varieties already on the market? There plenty of money invested there. Why do you need to reinvent the wheel?

He clearly has other things on his mind.
