In the deserts north of the Dead Sea, (and in many other parts of the world), growing crops is challenging. These locations get little to no rainwater, so every drop of water counts for survival of people and their food.
New research by engineers in Isreal have come up with a way to use the salty water that is abundant in aquifers far below the surface of the desert. Previously, one obvious problem has been desalinating the water so it can be used on crops. These researchers have developed a filter that uses much less energy than current standard technology, making it able to be run from small solar arrays. At the same time, they are experimenting with crops that actually like the saline wastewater which is a by-product of the desalination. In this way they are hoping to be able to provide low cost, off the grid solutions to countries in the Middle East and Africa that "are losing ground to desertification." Thanks to these engineers, what was previously a difficult venture could soon become a new mode of sustainable agriculture.
