With water scarcity a growing problem worldwide, University of California, Berkeley, researchers are close to producing a microwave-sized water harvester that will allow you to pull all the water you need directly from the air — even in the hot, dry desert.
You might expect that plants hoping to thrive in California’s boom-or-bust rain cycle would choose to set down roots in a place that can store lots of water underground to last through drought years. But some of the most successful plant communities in the state — and probably in Mediterranean climates worldwide — that are characterized by wet winters and dry summers have taken a different approach. They’ve learned to thrive in areas with a below-ground water storage capacity barely large enough to hold the water that falls even in lean years.
A century of water management in the western United States is on the verge of being restructured and two UC Berkeley water experts approve. Under a plan recently passed by Congress, the U.S. Secretary of the Interior is charged with implementing an agreement among seven states — Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming — in which each agrees to take less water from the Colorado River. The plan, more than two years in the making, now is headed to the desk of President Donald Trump for his signature.
