One hundred and thirty five litres of water go into the production of a single egg. For a kilogram of wheat, it’s 1,300. Over the course of its lifetime, a typical cow consumes more than 3 million litres – that’s 2,400 to each hamburger. The figures (all global averages) are startling. And, according Dutch academic and creator of the “<\/span>water footprint<\/a>” concept Arjen Hoekstra, present a compelling case for greater transparency in the food industry.<\/p>\n

Speaking at the Compassion in World Farming<\/a>’s annual Peter Roberts Memorial lecture in London on Monday night, Hoekstra said that a product’s water footprint – in other words the amount of freshwater used over the various stages of the production chain – can be significantly reduced if farmers, governments and consumers take action.<\/span><\/p>\n

For the agriculture industry, this means adopting precision irrigation (taking water directly to the plant’s roots, rather than spraying it widely which can save up to 50% of water); for governments, allowing water footprinting to influence other policy areas, such as trade and foreign policy; and for the public, demanding better labelling of products, Hoekstra said.<\/span><\/p>\n

Whether greater consumer awareness leads to better choices, however, is subject to debate. Growing understanding of the links between <\/span>meat and climate change<\/a> have, after all, tallied with huge rises in meat consumption – which is expected to double again by 2050.<\/p>\n
