Prof. Arjen Hoekstra on Virtual Water: The Water Footprint of Modern Society

In his address, Prof. Hoekstra discussed the concept of the 'water footprint', which he developed. Like a carbon footprint, the water footprint measures the amount of water used either directly or embodied indirectly in the goods we consume. Many countries and businesses have externalised their water footprint, importing water-intensive goods from elsewhere. As climate change and population growth place increasing pressure on water resources, Prof. Hoekstra outlined ways for businesses and governments to cut direct water consumption and supply chain consumption to sustainable levels.
