NEWS NOTES ON SUSTAINABLE WATER RESOURCES  Nabatean Water Technology  https://www.ancient-origins.net/ancient-technology/sophisticated-water-technologies-ancient-nabataeans-002193 ; The Nabataeans were an ancient Semitic people dating back to 586 BC, who inhabited northern Arabia and the Southern Levant. The desert climate created agricultural difficulties for the Nabataeans, but they rose to the challenge, creating a sophisticated water collection system, which allowed them to build an impressive trade empire in the heart of Arabia.The first records of the Nabataeans show that they lived in Edomite territory, although there is some dispute as to how and when the Nabataeans arrived there – some believe that they lived alongside the Edomites for hundreds of years, while others maintain that the Nabataeans migrated to the Edomite territory after the Edomites moved north. They eventually chose the site of Petra to build their city.The biggest challenge for the Nabataeans was the dry, arid climate of the canyon in which Petra was located. This made agriculture challenging, as they had to work towards ways to ensure that there would be an adequate water supply for the inhabitants and to support whatever they planted. One method for gathering water was to plant a single fruit tree in the middle of an area that had been contoured into a shallow funnel.  When it rained, all water would flow down into the center of the funnel, and would be sealed in by the silt-sized sediment called loess, and the water would be preserved. But their impressive water channeling technology included many other processes, including the construction of aqueducts, terraces, dams, cisterns, and reservoirs, as well as methods for harvesting rainwater, flood water, groundwater, and natural springs.  This article is not the usual technical product of research, but it still contains interesting facts about how sustainability was achieved long ago with primitive systems in an arid environment. Programs related to this work have aired on several TV channels.  Tim SmithSustainable Water Resources CoordinatorGovernment Web Site, https://acwi.gov/Sustainable Water Resources Site, https://sites.google.com/site/sustainablewaterresources/ ;
