Climate change is going to mean many changes for humanity, one of which is how we use our water. There will, in all likelihood, be less of it to go around for areas that don’t typically experience drought which begs another question. Are desert cities soon to be on their way out? Well it turns out that hot urban areas are already ahead of the water curve and could teach the rest of the world a thing or two.

Cities in very hot places like Arizona have been dealing with less water since their inception. They’re in deserts after all, temperatures regularly soar in the summer and don’t get drop all that much for the winter. These cities have already tackled many issues that more temperate urban areas are just beginning to grapple with.

Urban planning around water conservation and use has allowed these places to prosper and in the coming years, areas where it’s due to get hotter and drier should look to the places that have been dealing with this since forever for a guide on how to handle the coming heat.
