The ancient city of Petra, located at the crossroads of caravan routes in the desert of southern Jordan, is one of the most iconic treasures of the ancient world. Today the site is being impacted by catastrophic flooding due to climate change. However, local archeologists think they may have uncovered a solution buried in the desert: The ancient city itself. The site is filled with hidden systems of channels, dams, reservoirs, and cisterns that were carefully designed to collect and control water. If we can rebuild these, perhaps we can save Petra.
