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means that more than 80 percent of the water naturally available to agricultural, domestic, and industrial users is withdrawn annually—leaving businesses, farms, and communities vulnerable to scarcity.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...
Experts recently said that 20 million people in Africa's Sahel will face hunger this year, requiring $2 billion in food aid. The question is: Can the Sahel cost-effectively and sustainably increase food production?
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.
Many countries in Africa are rich with trees, wildlife, minerals, and other natural resources. But as new WRI research and an interactive map show, few national laws provide communities with strong, secure rights to the resources on their land.
WRI conducted a systematic review of the national framework laws for five natural resources—water, trees, wildlife, minerals, and petroleum—in 49 sub-Saharan African countries. The results are presented in our new Rights to Resources map.
