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.
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means that more than 80 percent of the water naturally available to agricultural, domestic, and industrial users is withdrawn annually—leaving businesses, farms, and communities vulnerable to scarcity.
This issue brief identifies the major types of uncertainties in water quality trading markets and summarizes the various mechanisms that could be used to address them.
Governments, businesses, development agencies, and NGOs are increasingly turning to economic valuation as a way to protect coral reefs and mangroves. This process makes the economic case for protection and sustainable use of natural resources by showing the monetary, employment, and infrastructure benefits ecosystems provide—metrics that are easily understood by decision-makers.
But not all economic valuations are created equal. WRI's new guidebook shows how NGOs and other stakeholders can conduct economic valuations in ways that lead to real change on the ground.
This guidebook details the steps in conducting a coastal ecosystem valuation to inform decision making in the Caribbean. It guides valuation practitioners—both economists and non-economists—through the three phases of a valuation effort (scoping, analysis and outreach), with an emphasis on...
