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.

Nearly Half of U.S. Fracking Sites Overlap with Water-Stressed Regions

A new report from CERES draws a connection between water risk and hydraulic fracturing in the United States. The report adds an important dimension to the conversation about how energy use and water stress will play out in the years ahead.

The report, Hydraulic Fracturing & Water Stress: Growing Competitive Pressures for Water, brings together Aqueduct’s high-resolution water stress maps with FracFocus.org data on the location and water use of U.S. shale oil and gas wells. The complete map (see below) shows where potentially water-intense hydraulic fracturing is happening in water-stressed areas.

The results of the study are eye-opening: Almost half of the more than 25,000 oil and gas wells mapped by Ceres are in water basins with either high or extremely high water stress.

Food and Fuel: 2 Grand Challenges Facing Us this Earth Day

Since the very first Earth Day more than four decades ago, the environmental movement has tackled a wide range of problems, including air pollution, contaminated water, deforestation, biodiversity loss, and more. But this Earth Day, I propose that there are two fundamental issues the movement must address over the coming decade if it is ever to defuse the tension between development and the environment. In fact, these two issues underlie many, if not most, of the world’s environmental challenges.

I’m referring here to the human quest for food and the human quest for fuel.

Unsustainable Food Production

Food production has significant―but often underestimated―impacts on the environment. Take climate, for instance: About one-quarter of the world’s annual greenhouse gas emissions are agriculture-related. In particular, nearly 13 percent of global emissions comes from livestock, fertilizer use, and farm-related energy consumption, while another 11 percent results from the clearing of forests and other ecosystems, primarily for agriculture.
