Can 'nexus thinking' alleviate global water, food and energy pressures?

As an introduction to their  'Water, food and energy nexus debates - live broadcast', happening on the 6th February; the Guardian are publishing a range of articles to support the debates.

Our very own Declan Conway has been quoted in the article Can 'nexus thinking' alleviate global water, food and energy pressures? about his research on water and energy use in China. Below is his contribution to the article:

"Many of the pressures we're talking about globally are all occurring within China," Conway says.

"It is the world's second largest irrigator, using a huge quantity of water for growing of crops, much of which is pumped from underground – and that requires a lot of energy. We recently found that 0.5% of China's total emissions come simply from the pumping of groundwater for irrigation."

Potential responses to these issues are still in their infancy, but China's next five year plan includes planning goals for energy efficiency and emissions, food production and water use, including "how much water goes into growing a particular crop," says Conway. "A lot of effort has gone into softening the blow on agriculture while incentivising much more efficient use of water."
