In South Africa—one of the world’s most water-stressed countries and one of the largest producers and consumers of coal—the water-energy nexus is a topic of great concern.
The shale gas revolution, which began nearly 10 years ago in the United States, is poised to spread across the globe. For many countries, shale gas could strengthen energy security while cutting emissions.
But unlocking this massive resource comes with a significant environmental risk: access to freshwater for drinking, agriculture, and industrial use.
Learn how securing water and shale gas could strengthen energy security while cutting emissions.
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.
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.
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.
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.
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.
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.
