caption_attribution_description: English: Potential peak water curve for production of groundwater from an aquifer. This graph shows a peak oil type production curve for water after production rates surpass the natural recharge rate.
context_page_description: Peak water is a concept that underlines the growing constraints on the availability, quality, and use of freshwater resources.
  Peak water was defined in a 2010 peer-reviewed article in the Proceedings of the National Academy of Sciences by Peter Gleick and Meena Palaniappan. They distinguish between peak renewable, peak non-renewable, and peak ecological water in order to demonstrate the fact that although there is a vast amount of water on the planet, sustainably managed water is becoming scarce.
  Lester R. Brown, president of the Earth Policy Institute, wrote in 2013 that although there was extensive literature on peak oil, it was peak water that is "the real threat to our future". An assessment was published in August 2011 in the Stockholm International Water Institute's journal. Much of the world's water in underground aquifers and in lakes can be depleted and thus resembles a finite resource. The phrase peak water sparks debates similar to those about peak oil. In 2010, New York Times chose "peak water" as one of its 33 "Words of the Year".
  There are concerns about impending peak water in several areas around the world:

  There are concerns about impending peak water in several areas around the world:
  Peak renewable water, where entire renewable flows are being consumed for human use
  Peak non-renewable water, where groundwater aquifers are being overpumped (or contaminated) faster than nature recharges them (this example is most like the peak oil debate)
  Peak ecological water, where ecological and environmental constraints are overwhelming the economic benefits provided by water use
  If present trends continue, 1.8 billion people will be living with absolute water scarcity by 2025, and two-thirds of the world could be subject to water stress. Ultimately, peak water is not about running out of freshwater, but about reaching physical, economic, and environmental limits on meeting human demands for water and the subsequent decline of water availability and use.
