Managing the Earth from Space: Satellite and Sensing Technology in Water Management

WRI experts Betsy Otto, Charles Iceland, Tien Shiao, and Paul Reig will attend World Water Week in Stockholm next week. Among other activities, they’ll co-host a session on using satellite data to map global water risks. Here, Andrew Maddocks explores the role that satellite data can play in improving water management. Learn more about WRI’s World Water Week Activities.

New Study Raises Question: What Don’t We Know About Water Scarcity?

A new study from the United States Geological Survey (USGS) reveals troubling news: The aquifers that millions of Americans rely on for freshwater are being depleted at an accelerating rate. In fact, aquifer depletion in the years between 2004 and 2008 was nearly triple the historical average.

Population growth and increasing demand—in particular for irrigating crops—are straining these underground freshwater sources. In many cases, aquifers have accumulated over the course of millions of years.

There are two lessons we take away from this USGS study:

  1. Growing demand is increasingly coming into conflict with our finite global water supply. Even in places that are historically water-abundant, growth in water demand is outstripping available supply. (That’s why WRI’s Aqueduct project focuses on water stress – the ratio of water supply and demand – more than measures of water quantity.)
