peak water
On Significant Figures, Peter Gleick explains that growing populations worldwide have exerted peak pressures on water supplies, leaving entire regions more vulnerable to natural variations in rainfall. In turn, global warming has made these natural variations more extreme. One such variation is El Niño, when "droughts are typically more widespread and severe." Dr. Gleick reports on the challenges faced around the world in 2016, as several historic droughts grow worse. Meanwhile, in honor of Earth Day, Ethan Siegel suggests we count our blessings: "there’s still no planet as friendly to life…
Populations around the world face many severe water challenges, from scarcity to contamination, from political or violent conflict to economic disruption. As populations and economies grow, peak water pressures on existing renewable water resources also tend to grow up to the point that natural scarcity begins to constrain the options of water planners and managers. At this point, the effects of natural fluctuations in water availability in the form of extreme weather events become even more potentially disruptive than normal. In particular, droughts begin to bite deeply into human well-being…

It is no surprise, of course, that the western United States is dry. The entire history of the West can be told (and has been, in great books like Cadillac Desert [Reisner] and Rivers of Empire [Worster] and The Great Thirst [Hundley]) in large part through the story of the hydrology of the West, the role of the federal and state governments in developing water infrastructure, the evidence of droughts and floods on the land, and the politics of water allocations and use.
But the story of water in the West…
OK, put away your guns. We’re not talking shooting wars, at least not yet, at least not in the U.S. We’re talking politicians shooting off their mouths, political wars, and court battles. But water is serious business.
But it is a different story around the world, where there is a long and sad history of violent conflict over water. At the Pacific Institute we maintain the Water Conflict Chronology, documenting examples going back literally 5,000 years.
As others have pointed out, water can be – and often is – a source of cooperation rather than conflict. But conflicts over water are real.…
