Man-made climate change has reduced global agricultural productivity by about 21 per cent since 1961, a slowdown that is equivalent to losing the last seven years of productivity growth, according to international research. In Australia, the researchers estimated we have seen a 20 to 25 per cent reduction. The study also found that global agriculture has grown more vulnerable to ongoing climate change.
