USE WATER BETTER TO AVOID CLIMATE CHANGE IMPACT ON WORLD FOOD
February 23, 2016 / Glen Reynolds
Although growing human numbers, climate change and other crises threaten the world’s ability to feed itself, researchers believe that if we used water more sensibly that would go a long way towards closing the global food gap.
Politicians and experts have simply underestimated what better water use can do to save millions of people from starvation, they say.
For the first time, scientists have assessed the global potential for growing more food with the same amount of water. They found that production could rise by 40%, simply by optimising rain use and careful irrigation. That is half the increase the UN says is needed to eradicate world hunger by mid-century.
