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.

The geography of black rice

Sometimes it pays to spend some time in Genebank Database Hell, if you can fight through the pain.

You may remember a piece recently about the antioxidant properties of black rice. But where does black rice come from? Well, hanging around with the Genesys and GRIN-Global crowd in the past couple of days has allowed me to come up with this map in answer to that deceptively simple question.

In yellow are all the rice accessions from Asia which have coordinates, as recorded in the IRRI database, EURISCO and GRIN. In red are the black rice accessions.

You’d have thought such a map would be pretty easy to make. But you’d be wrong. I had to get an Excel spreadsheet from IRRI with the characterization data, ((For which many thanks!)) and mash it up with the passport data in Genesys for the same accessions, and then export two separate kmz files and fiddle around in Google Earth. ((Thanks to Google for the Pro license!)) Well, they don’t call it Genebank Database Hell for nothing. But it is getting better, slowly but surely.
