Widespread hunger and poverty are predicted unless strategies are developed to cope with the drop in crop yields climate change will cause.
LONDON, 22 December, 2014 – New research predicts that climate change will transform agriculture, with a drop in yields of up to 18% by 2050 in terms of calories harvested. By then, the global population will have risen by more than 18%, so the consequences could be calamitous.
That’s the worst projected outcome. By the same date, the researchers say, yields in terms of calories could have risen by 3%, but that would still mean widespread hunger and poverty. >>
Demand for irrigation may grow by up to 25% as temperatures rise.
