Cambridge, US: Students at the Harvard Graduate School of Design, Cambridge, US, developed an online map that takes a look at the “water footprint” of countries around the world. The interactive map is accessible at https://www.josephbergen.com/viz/water/. It allows users to compare water supply and consumption between nations, among other stats. The data visualisation compiles data on water consumption as well as the hidden water content in consumer goods in order to determine the differing amount of water consumed per person as well as the water supply.
The map also includes a tool to display the embodied water in a number of different products, which can also be compared to one another (or to a country’s per capita water use).The site takes into account the amount of water it takes to produce consumer goods such as beverages, fast food, clothing, and footwear as well as the agricultural requirements of different agricultural crops and livestock.
Data for the visualisation comes largely from reports produced by the Pacific Institute, which has a long history of looking at the world’s water issues, including their biennial series of reports on The World’s Water.
