The cost of 'virtual water'

A presentation by Arjen Y. Hoekstra of the Water Footprint Network was one of the most interesting I heard at the World Water Forum this spring, prompting all sorts of questions about water footprints vs. carbon footprints and when it might not be best to produce goods locally -- subjects that I could barely give a glancing look in a short news piece for the latest issue of Sierra. Working on it certainly piqued my interest in the topic further; hope it does the same for readers.

Read my article on water footprints, "Fluid Measures," in the July/August 2009 issue of Sierra magazine.
