African cereal systems mapped

It’s over a year old, but I’ve only just learned about the ILRI publication “A production system map for Africa.” Looks interesting. I’ll just reproduce here the map showing the extent of different cereal-based system, with the main species involved. Looks like Angola is the most cereal-diverse country in sub-Saharan Africa. As with all such maps, one (or at least I) longs to plonk the locality of germplasm accessions on top of it. And to know how they relate to other crop maps produced by the CGIAR system.

Climate change winners and losers in Europe: the story so far

A recent paper in Agricultural Systems looks at what’s happened to the potential yields of eight crops (winter wheat, spring barley, maize, winter rapeseed, potato, sugar beet, pulses and sunflower) in Europe from 1976 to 2005. Italy and central and eastern Europe have been the big losers (left), probably due to higher temperature increases, sometimes in combination with lower radiation values.

And the British Islands have been the big winners (right), due to to longer period during which temperature is optimum for CO2 assimilation, sometimes in combination with higher radiation levels. That, of course, cannot last forever, though.
