Gaps in cassava collection in Africa highlighted

A request from MapSpaM for people to help them in mapping the distribution of cassava cultivation in Africa ((You may remember us mentioning MapSpaM before as part of an ongoing discussion of crop distribution data.)) forced me into some more playing with Google Earth. I just took MapSpaM’s draft cassava map…

…and plonked on top of it the germplasm provenance data from Genesys. Here’s the result (right click to save the kmz file):

Which highlights — not for the first time, but very powerfully — the lack of material from eastern and southern Africa in the international genebanks. It is definitely important to think about safety duplicating national collections from those countries.

Here’s a close-up for West Africa:

Pretty good representation overall, but even here there are some definite gaps. Time to get collecting again in Africa too. Though of course a geographic gap is not necessarily a genetic gap…

More lessons from Egypt

For no other reason than that I like playing with Google Earth, here’s a map of Egyptian germplasm in the Millennium Seed Bank (red dots), which are duplicates of some of the material at the recently looted Deserts Gene Bank, and in Genesys (which covers the CG Centre genebanks contributing to SINGER, the European genebanks contributing to EURISCO, and the genebanks of the USDA system). The red markers are wild material, the green cultivated.

Now, do you see that row of green markers in the middle of the desert in the south of the country?

Those turn out to be various vegetables from three different genebanks in the USA and Europe. Which nicely illustrates the usefulness of bringing datasets together. And playing with Google Earth.
