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.

Majority of China’s Proposed Coal-Fired Power Plants Located in Water-Stressed Regions

To maintain its economic growth and provide for its massive population, China must reconcile two powerful, converging trends: energy demand and resource scarcity. One prime example of this tension is the country’s coal use and water supply.

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.)

Step-by-Step Guidance on Corporate Water Disclosure

Investors need to understand a wide variety of business and market risks facing the companies in which they invest. In the 21st century, that includes water risks.

An increasing number of companies are experiencing detrimental water-related business impacts, including operational or supply chain disruptions and property damage from flooding, to name a few. These impacts can be costly--in 2011 they cost some companies up to $200 million--and have caught the attention of investors around the world.

As a result, the movement toward increased Corporate Water Disclosure is gaining speed. The deadline for companies to respond to the CDP 2013 Water Disclosure Questionnaire is six weeks away. To make the reporting process easier, WRI has aligned our Aqueduct Water Risk Atlas with CDP’s water questionnaire. Together, we are providing step-by-step guidance on how to measure and report exposure to water-related risks.
