My first look at Aqueduct Water Risk Atlas was one of those moments. Aqueduct is a project that measures, maps, and increases understanding of water risks around the globe. The World Economic Forum identified water supply crises as one of the highest impact and most likely risks facing the planet. Recognizing and understanding what type of risks and where risks exist is the first step to averting dire consequences.
The non-profit World Resources Institute spent three years working with a myriad of partners to create an interactive maps of the world and water risks with data cumulated from peer-reviewed research. These maps, data, and databases are open to everyone free of charge. Check the World Risk Atlas out here. It's definitely worth a look and taking the time to play around a little on it. So far I've found it fairly intutive and easy to use, but I'm sure there's a lot of tools I haven't even found.
