World Rivers Day is coming up in late September, so we're thinking about water around The Big Wild offices. As that cliche goes, "the next war won't be fought over oil, it'll be fought over water".
So where exactly are the world's water resources? Who has too much, and who doesn't have enough? To answer these questions, we turned to the excellent University of Sheffield resource
Worldmapper. They revisualize maps of the Earth based on a particular factor, and create some great educational resources.
We explored the site, and found a handful of great maps for water resources. In each case you can click the map to view a larger version of it.
