"Nothing is more important to life than water, and no one knows water better than Sandra Postel. Replenish is a wise, sobering, but ultimately hopeful book." —Elizabeth Kolbert
"Remarkable." —New York Times Book Review
"Clear-eyed treatise...Postel makes her case eloquently." —Booklist, starred review
"An informative, purposeful argument." —Kirkus
We have disrupted the natural water cycle for centuries in an effort to control water for our own prosperity. Yet every year, recovery from droughts and floods costs billions of dollars, and we spend billions more on dams, diversions, levees, and other feats of engineering. These massive projects not only are risky financially and environmentally, they often threaten social and political stability. What if the answer was not further control of the water cycle, but repair and replenishment?
Sandra Postel takes readers around the world to explore water projects that work with, rather than against, nature’s rhythms. In New Mexico, forest rehabilitation is safeguarding drinking water; along the Mississippi River, farmers are planting cover crops to reduce polluted runoff; and in China, “sponge cities” are capturing rainwater to curb urban flooding.
Efforts like these will be essential as climate change disrupts both weather patterns and the models on which we base our infrastructure. We will be forced to adapt. The question is whether we will continue to fight the water cycle or recognize our place in it and take advantage of the inherent services nature offers. Water, Postel writes, is a gift, the source of life itself. How will we use this greatest of gifts?
