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means that more than 80 percent of the water naturally available to agricultural, domestic, and industrial users is withdrawn annually—leaving businesses, farms, and communities vulnerable to scarcity.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.

India’s Watershed Development Boosts Food Security, Improves Livelihoods

India struggles with water scarcity, a problem that poses especially huge implications for the country’s food security and rural livelihoods. The country has long-battled its scarcity issues through Watershed Development, a participatory approach to improve water management through afforestation and reforestation, sustainable land management, soil and water conservation, water-harvesting infrastructure, and social interventions. But while watershed development has been employed in communities throughout India, its potential long-term costs and benefits have not been well-understood or studied--until now.

A new working paper from WRI and WOTR finds that watershed development has provided more than $9 million dollars’ worth of food security and water management benefits to the water-stressed community, Kumbharwadi.

Watershed Development in India

Economic Valuation and Adaptation Considerations

Watershed development, an ecosystem-based approach for development of rain-fed regions in India, is gaining traction and political support, but how is it contributing to poverty reduction, food security, and climate change adaptation? This paper examines how economic valuation can improve our...

World’s 36 Most Water-Stressed Countries

WRI’s Aqueduct project recently evaluated, mapped, and scored water risks like these in 100 river basins, ranked by area and population, and 180 nations—the first such country-level water assessment of its kind. We found that 36 countries face “extremely high” levels of baseline water stress (see list at bottom). This means that more than 80 percent of the water available to agricultural, domestic, and industrial users is withdrawn annually—leaving businesses, farms, and communities vulnerable to scarcity.

Aqueduct Country and River Basin Rankings

A Weighted Aggregation of Spatially Distinct Hydrological Indicators

More and more countries around the world face high levels of water stress, but measuring and communicating that stress consistently is challenging. This paper ranks countries and river basins worldwide based on their exposure water-related risks. Specifically, it provides national and basin-...
