Okay, I hadn’t previously looked very closely at the 12 tightly packed graphs on page 23 of the Copenhagen Synthesis Report, indicating anticipated changes in food production across the world.
But now that I have — that pink bar indicating the likely range of decline for maize production in Southern Africa is one of the most conspicuous. (Another is in East Africa, where they are likely to see a 30% INCREASE in barley yields. But that dramatic shift is indicated as being less important for hunger.)
The colours, by the way, indicate the importance of the change for hunger, with pink indicating greater importance.
In other words, according to the latest science, we in Southern Africa can expect a 30% decline in maize yields over the next 20 years. And wheat – down 15%. Seen that in any headlines?
