We spend billions of dollars on irrigation, dams, sanitation plants, and other feats of engineering to control water for our own prosperity. What if the answer was not control, but replenishment? Sandra Postel takes readers around the world to explore water projects that work with, rather than against, nature's rhythms. Forest rehabilitation is safeguarding drinking water, farmers are planting cover crops to reduce polluted runoff, and "sponge cities" are capturing rainwater to curb urban flooding. Postel argues that efforts like these will be essential as we adjust to a hotter, wilder climate. Will we continue to fight the water cycle, endangering ourselves and the planet, or recognize our place in it and take advantage of the inherent services nature offers?

Sandra Postel is director of the Global Water Policy Project and co-creator of Change the Course, the national water stewardship initiative awarded the 2017 US Water Prize for restoring billions of gallons of water to depleted rivers and wetlands. From 2009-2015, she served as Freshwater Fellow of the National Geographic Society. Postel is author of Pillar of Sand: Can the Irrigation Miracle Last? and Last Oasis: Facing Water Scarcity, the basis for a PBS documentary. Her work has appeared in Science, Natural History, and Best American Science and Nature Writing.

"In Replenish, Sandra Postel travels the world to reveal both our biggest water challenges and the new, smart solutions needed for the 21st century. Replenish is not just restorative as its title implies; it is also wonderfully refreshing and deeply satisfying."--Brad Udall, Senior Water and Climate Scientist/Scholar, Colorado Water Institute, Colorado State University
