WATER

A tour de force world history focused on water and how we use it.

Climate scientist Boccaletti, chief strategy office of the Nature Conservancy, begins with an emphatic denial that “water is an inert backdrop on the stage of human events.” To prove his thesis, he delivers an expert water-centered history of human progress from the time we became sedentary 10,000 years ago. “The story of water,” writes the author, “is not technological, but political.” Agriculture produces far more food than hunting and gathering but requires massive amounts of water. Depending on rain is unreliable, so centuries ago, farmers began to harness the power of wells, local rivers, canals, and irrigation projects, which preoccupied early governments as much as warfare. Ambitious cultures paid attention to transportation by water, which is 10 times more efficient than by land. In Boccaletti’s view, an essential feature of the rise of the nation-state in the 17th century was increased security of property, which produced an explosion of investment in water infrastructure. By the end of the 19th century, he writes, the “great American rivers…would become the basis for the rise of the American republic as the dominant economy of the twentieth,” the “hydraulic century.” Hydropower, not hydrocarbons, powered the electrification of America. Opening with the spectacular Panama Canal in 1904, the U.S. spent much of the 20th-century attempting to repeat the success of the Tennessee Valley Authority and Hoover Dam around the world, with spotty success. These efforts peaked during the 1970s, after which water-led development seemed to fall out of fashion—until, out of the blue, China appeared on the scene, built the Three Gorges Dam (“the largest single piece of infrastructure in the world”), and took the lead in spreading its technology around the world. “It may still be that if the twentieth was the American Century,” writes Boccaletti in this astute global study, “the twenty-first will be the Chinese one.”

An ingenious lesson in geopolitics.
