High Water Stress Jeopardizes One-Third of World’s Corn Crop

According to a new report, the $65 billion U.S. corn industry faces a range of water-related risks that could disrupt production. Other countries face similar threats. In fact, one-third of the world’s corn production occurs in highly or extremely highly water-stressed regions.

Identifying the Global Coal Industry’s Water Risks

Regional water concerns are creating significant financial risks due to advanced global commodity trading and energy industries’ high dependence on water.

Our Aqueduct project explores how water risks are already impacting the world’s coal industry, and how risks will change over time.

Water Stress Magnifies Drought’s Negative Impacts throughout the United States

Years of Living Dangerously, a new Showtime series about climate change, turned its lens on how drought devastated the small town of Plainview, Texas in its first episode. In Plainview—and every other drought-stricken place across the United States—a precipitous drop in rainfall is only part of a much broader story. Underlying water stress is one important piece of that complicated puzzle. When drought strikes where baseline water stress is high, it exacerbates regions’ water woes.

Drought Is Only One Explanation for California’s Water Crisis

As California lawmakers move forward with potential solutions to the state’s current water shortage, it’s important to consider the full context of underlying reasons for California’s water vulnerability.

Our research shows that about 66 percent of the state’s irrigated agriculture—its biggest water user—faces extremely high levels of baseline water stress. This means that more than 80 percent of the available water supply is already being used by farms, homes, businesses, and energy producers. It’s clear that even without drought, the state would be in trouble.

Water Stress by Most Populous River Basins

This map shows the average exposure of water users in each river basin to water stress, the ratio of total withdrawals to total renewable supply in a given area. A higher percentage means more water users are competing for limited supplies.

World’s 18 Most Water-Stressed Rivers

WRI’s Aqueduct project recently evaluated, mapped, and scored stresses on water supplies in the 100 river basins with the highest populations, 100 largest river basins, and 180 nations. We found that 18 river basins—flowing through countries with a collective $US 27 trillion in GDP—face “extremely high” levels of baseline water stress. This means that more than 80 percent of the water naturally available to agricultural, domestic, and industrial users is withdrawn annually—leaving businesses, farms, and communities vulnerable to scarcity.

Multinationals Need to Take Notice and Take Action on Water Risk Data

New research from the World Resources Institute scores water-related risks facing 180 countries and 100 river basins. This is the first national-level data of its kind, evaluating competition for available water supplies, annual and seasonal supply variability, flood occurrence, and drought severity.

The data paints a country-level picture of water risks, information that is clearly relevant for national policymakers. But this research also holds huge implications for the private sector—particularly for shareholders and investors, corporate operations, and corporate supply chains. Multinational businesses should take notice—and take action.

5 Things We Learned in 2013 that Could Move the Needle on Sustainability

Two and a half millennia ago, Plato announced that “Human behavior flows from three things: desire, emotion, and knowledge.” Unfortunately, our human and corporate behavior on climate change is not even close to where it needs to be. But if the great philosopher was right (and he usually was), 2013 may have been a game changer.

The big news from 2013 came from gains in knowledge. New tools and research are opening our understanding much wider than before. But will we act on this? Knowledge can spur action, but this path is not guaranteed.

WRI’s Top Outcomes of 2013

As 2013 comes to a close, it’s a good time to look back on the impact we’ve made in the world this year.

We made progress on tackling key sustainability challenges, including addressing climate change, promoting clean energy, ensuring food security and stable water supplies, reducing forest degradation, and creating sustainable cities. Take a look at our nine top outcomes:
